Abstract

An apparatus having at least one spring clip (12) disposed on a connector adapter housing (52, 52') for releasably mating with an opening in an enclosure, the housing having fiber optic cables connected to opposed ends of the housing. When connected through an opening in an enclosure, the connector adapter housing maintains alignment of the opposed fiber optic cables for optical communication. The spring clip includes at least one clip member (18, 28) disposed upwardly from the surface of the spring clip. The spring clip is slidably inserted through a groove (62, 64) on at least one surface of the aligned connector housings. For release of the aligned connector housings, the spring clip is manipulated to slide along the groove, to compress the at least one clip member, allowing the housing to be removed from the enclosure opening for separation of the fiber optic cables from optical communication.

Description

TITLE OF INVENTION Spring Clip Assembly For Fiber Optic Adapter

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0001] Not Applicable BACKGROUND OF THE INVENTION [0002] This invention relates to a fiber optic cable adapter. More specifically, the present invention relates to a quick disconnect spring clip assembly for fiber optic cable connection adapters. [0003] Fiber optic cables are commonly used for signal transmission. In order to facilitate the use of fiber optic cables, various connectors are employed to temporarily connect and align fiber optic cables at a control panel or housing. Such connections typically include a component which is mounted in a panel opening or a wall opening, and which has a split sleeve for receiving and supporting the ends of two cables. The connection typically includes cable connectors which mate with the first panel adapter. The cables have a ferrule and utilizes the other end of the split sleeve for receiving and supporting the end of the second cable in alignment with the end of the first cable. The adapter component generally is provided with some means for releasably securing the adapter connector component in the panel opening or wall opening. A typical panel-mounted connector adapter utilizes a pair of retaining clips which expand against an interior surface of the panel once the component has been inserted into the panel opening. The expanded retaining clips prohibit the connector adapter component from being removed from the opening unless selective compression is applied on the clips from within the interior of the panel, therefore requiring an operator to attain access to the interior of the panel. [0004] It has been recognized that where panel-mounted connectors are used, it is important that the cable ends, and ferrule end connections, be clean and smooth to insure efficient signal transmission. Accordingly, frequent disassembly and cleaning of the connectors and cable ends is desirable. Where panel-mounted connectors with retaining clips are used, the connectors must be removed for cleaning periodically with minimal access into the interior of the housing in which the connector components are mounted. Therefore, there is a need for a clip fastener attachable to a housing connector adapter, having a fiber optic cable attached thereto, to provide ease of disassembly of the housing connector adapter and fiber optic cable from the exterior side of a panel or housing. BRIEF SUMMARY OF THE INVENTION [0005] In accordance with the present invention, there is provided an apparatus for releasably mating a connector system to an enclosure or panel, with the connector system having one or more fiber optic cables connected thereto. The apparatus includes a spring clip having a first clip member and a connector housing having a first distal end and a second distal end connectable together in an aligned configuration for insertion of the second distal end into an opening in the enclosure. The spring clip is in slidable communication with the first and second distal ends of the mating adapter housing. A retaining clip is attached to the second distal end of the connector housing for selectively compressing the first clip member of the spring clip when the spring clip is manipulated by an operator. Upon compressing of the first clip member against the retaining clip, the spring clip is moved toward the second distal end by the operator for removal from the opening of the connector housing. [0006] One embodiment includes a first and a second connector housing of like configuration, with the connector housings connected in aligned orientation for insertion into an opening in an enclosure. Each connector housing includes a pair of connector grooves aligned on opposed sides of each connector housing. When the connector housings are aligned end-to-end, each spring clip is insertable into respective connector grooves for releasably mating the connector housings into the opening of the enclosure. [0007] Each spring clip includes a first insertion end and a second end, and at least one clip member on each spring clip. The first insertion end is insertable into one connector groove of one connector housing, and is insertable through an opening through a flange on the proximal end of the first connector housing, for extension into an aligned connector groove of the second housing when the housings are aligned end-to-end. Extending from a first surface of each spring clip is at least two clip members including a first clip member and a second clip member disposed in opposing relationship on the first surface of the spring clip. The first and second clip members each have a free end extended out of the horizontal plane of the spring clip. [0008] To release the connector housings from the opening in the enclosure, the operator manipulates the second clip member of each spring clip and compresses the second clip member toward the horizontal plane of the spring clip, thereby allowing each spring clip to slide inwardly toward the second connector housing positioned interior of the enclosure along each respective connector groove. Upon movement of each spring clip along the length of each groove, the first clip member is biased against a retainer clip on an interior end of the second connector housing, therefore compressing the first clip member to bend toward the horizontal plane of the spring clip, allowing the first and second connector housings to be removed from the opening in the enclosure. The respective optic fiber cables are then inspected and disconnected from each connector housing without removal of the enclosure, thereby facilitating cleaning and repositioning respective fiber optic cables in alignment for optical communication.

109 DETAILED DESCRIPTION OF THE INVENTION

110 [0022] A connector adapter assembly 10 including a spring clip 12 and a

111 connector adapter housing 52 of the present invention as illustrated generally in

112 Figure 1, for releasably mating with a second housing adapter connector 52' of

113 like configuration. The spring clip 12 and the connector housing 52 provide a

114 system for releasably connecting and aligning a pair of fiber optic cables

115 positioned on opposed sides of an enclosure or panel 84. As illustrated in Figure

116 1, the connector assembly 10 is configured to allow insertion and removal of

117 spring clips 12, 12' from respective connector grooves 62, 64 positioned on each

118 like configured connector housing 52, 52', without requiring an operator to

119 access the interior of an enclosure 84 to which the connector assembly 10 is

120 releasably mated thereto.

121 [0023] Figure 1 and 4a illustrate one embodiment of the connector

122 assembly 10 that includes a plurality of components, including at least two

123 spring clips 12, 12', each having generally planar upper and lower surfaces.

124 Each spring clip 12, 12' is slidably connectable to opposed sides of respective

125 connector housings 52, 52'. The spring clip 12 may be composed of a material

126 such as spring steel having a thickness of about one rnillimeter to about three

127 millimeters. Each spring clip 12, 12' includes at least two clip members 18, 28

128 disposed in aligned and opposing relationship on the same surface of the spring

129 clip 12 (see Fig. 2). The spring clip 12 includes a first insertion end 14, a second

130 end 16, and a mid-portion 26 at about the middle of the linear length of each

131 spring clip 12, 12'. 132 [0024] The first clip member 18 is extended outwardly from the generally

133 planar first surface of the mid-portion 26 of the spring clip 12, and includes an

134 origination end 22 connected to the spring clip 12 proximal to the insertion end

135 14. The first clip member 18 includes a free end 20 that is positioned proximal

136 to the mid-portion 26 of the spring clip 12 in an unbent position (see Fig. 1 and

137 2) above the generally planar first surface of the mid-portion 26. The height of

138 the free end 20 above the spring clip 22 is determined by the angle of the first

139 clip member 18 relative to the surface of the mid-portion 26 of the spring clip 12.

140 [0025] One embodiment of the spring clip 12 includes a length 24 of the

141 first clip member 18 extending a pre-selected distance from the origination end

142 22 to the free end 20 of the clip member 18. The angle of the first clip member

143 18 allows the free end 20 to be positioned at a height of about one millimeter

144 above the horizontal plane of the spring clip 12. The free end 20 is bendable to a

145 second position (not shown) toward the horizontal plane of a first surface of the

146 spring clip 12 by direct manipulation by an operator, if the operator is provided

147 access to the insertion end 14 when installed on a connector housing 52. Upon

148 insertion of spring clip 12 on at least one side of connector housing 52 (see Fig. 1

149 and 3), the free end 20 is bent upon passage of the insertion end 14 through an

150 opening 68 in connector housing 52. The free end 20 returns to the unbent

151 position after passage through the opening 68, with the insertion end 14

152 positioned on the distal side of first connector seating flange 76.

153 [0026] Referring to Figure 2, the second clip member 28 includes an

154 origination end 32 connected in bent configuration proximate to the spring

155 member second end 16. The second clip member 28 includes a free end 30 that

156 is positioned proximal to the mid-portion 26 of the spring clip 12 in a first,

157 neutral position (see Fig. 2) above the horizontal plane of the linear length of the

158 spring clip 12. The origination end 32 includes at least two bendable portions,

159 including a first bend proximate to the origination end 32 of the second end 16,

160 and a second bend 34 spaced apart from the first bend along the length of the

161 second clip member 28. The second bend 34 is angled at a selected angle to

162 position the length 36 of the second clip member 28 in a generally parallel,

163 spaced-apart orientation with the first surface of the spring clip 12. In one

164 embodiment, the free end 30 is maintained at a height of one millimeter to two

165 millimeters above the planar first surface of the spring clip 12 when the second

166 clip member 28 is in an unbiased configuration. The free end 30 is resiliently 167 bendable to a second position (not shown) toward the first surface of the spring

168 clip 12 by manipulation by an operator of a spring member 40 attached to the

169 second end 16 of the spring clip 12.

170 [0027] Referring to Figures 1, 2, and 4a, the spring member 40 is formed

171 as an articulated arm assembly extension of the spring clip second end 16. The

172 spring member 40 is composed of a material such as spring steel or another

173 resilient material that is flexible and repetitively returns to an original position

174 after manipulation. The spring member 40 includes a cantilevered end 42 biased

175 in a position proximate an upper surface of the second clip member 28 at about

176 the second bend 34 portion. The cantilevered end 42 is biased against the upper

177 surface of the second clip member 28 by pressure applied against an actuator

178 side 44 and/or an end of the spring member 40 proximate to second end 16.

179 The spring clip 12, clip members 18, 28, and spring member 40 are composed of

180 resilient material such as a lightweight metal. The various components of the

181 spring clip 12 may be formed by selectively bending a portion of material to

182 obtain the configuration illustrated in Figure 2. The lightweight metal may

183 include spring steel or a similar composite material that is bendable and

184 resiliently returns to an original shape after repetitive manipulations.

185 [0028] Referring to Figures 1 and 4a, at least two spring clips 12 are

186 connectable to a first connector housing 52 having a pair of connector grooves

187 62, 64 on opposed exterior sides of the housing 52. A first distal end 54 of the

188 housing 52 encloses a central opening 56 for insertion of an optic fiber cable end

189 80 (see Fig. 5). A first connector groove 62 is extended along a first side of the

190 housing 52 to a second end 58 of the housing. The first connector groove 62 is

191 aligned with the length axis of the housing 52. A second connector groove 64 is

192 extended along a second side of the housing 52 opposed from the first side, to

193 the second end 58 of the housing . The second connector groove 64 is aligned

194 with the length axis of the connector housing 52. Each groove 62, 64 extends

195 respectively through a generally rectangular opening 68 through respective first

196 connector seating flange 76 and second connector seating flange 78 proximate

197 the second end 58 of the housing 52. The second end 58 encloses a second

198 central opening 60 through which an interior conduit 66 (see Fig. 3) may be

199 positioned for extension from the first distal end 54 to the second end 58 of each

200 housing 52, 52'. The first connector seating flange 76 and the second connector

201 seating flange 78 are each extended from the second end 58 in perpendicular 202 configuration from respective first and second opposed sides of the exterior

203 surface of each housing 52, 52'.

204 [0029] In one embodiment illustrated in Figure 1, first and second like

205 configured housings 52, 52' are releasably mounted together with second end 58

206 of the first housing positioned against second end 58' of second housing. In an

207 alternative embodiment illustrated in Figure 4a, first and second like configured

208 connector housings 52, 52' are fused together at the proximal or second ends 58,

209 58' to form a rigid length of connector housing 52, 52', to which the respective

210 spring clips 12, 12' are attached.

211 [0030] On the distal end 54' of connector housing 52' (see Fig. 5 and 7), a

212 restraining means is positioned, such as a restraining clip 46 positioned around

213 at least two sides of the distal end 54'. As illustrated in Figure 4b, the

214 restraining clip 46 includes a U-shaped configuration having a central restraint

215 segment 48 that connects two opposed segments 50, 50' which fit around the

216 first distal end 54 of the connector housing 52. When the central restraint

217 segment 48 is positioned on the second distal end 54', the segment 48 provides

218 pressure against the first clip member 18, when the spring clip 12 is

219 manipulated by the operator to slide along groove 62 toward the second distal

220 end 54', thereby bending first clip member 18 toward the plane of the surface of

221 the mid-portion 26 (see Fig. 7 and 8a).

222 [0031] To facilitate proper aligning of optic fiber cable ends 80, 82 (see Fig.

223 7) connected in each opposed distal ends 54, 54', and to provide for quick-

224 disconnect for connector housing 52, 52' from an enclosure 84, a method of

225 releasably connecting the connector assembly 10 is disclosed. The method

226 includes removably inserting a pair of spring clips 12, 12' into respective grooves

227 62, 64 on each housing (see Fig. 1, 4a, and 7). The step of inserting each spring

228 clip 12, 12' includes inserting along each respective groove 62, 64 so that

229 insertion end 14 is extended through openings 68, 68' by depressing first clip

230 member 18 and extending through openings 68, 68'. Upon passage through

231 openings 68, 68', each free end 20 of first clip member 18 resumes a height of

232 about one millimeter to about two millimeters above the horizontal plane of the

233 first surface of each spring clip 12, 12', therefore locking each first clip member

234 18 on an interior side of first connector seating flanges 76, 76' and second

235 connector seating flanges 78, 78' (see Fig. 4a and 7). Upon insertion of each 236 spring clip 12 along each respective groove 62, 64, the first clip member 18 and

237 second clip member 28 are maintained in an extended configuration above the

238 plane of the first surface of each spring clip 12, 12', therefore limiting movement

239 of each spring clip 12 along each respective groove 62, 64.

240 [0032] The step of disconnection for the connector housing 52, 52' from an

241 opening in an enclosure 84 includes manipulation of actuator member 44 of

242 spring member 40 (see Fig. 8a), to compress the second clip member 28, with

243 allows second clip member 28 and spring clip 12 to slide through openings 68,

244 68' of first and second connector seating flanges 76, 76,' (see Figs. 8b and 8c).

245 By sliding spring clip 12 toward second housing 52', the insertion end 14 moves

246 along connector groove 62, which forces first clip member 18 against restraint

247 segment 48 of restraining clip 46. When first clip member 18 is forced under

248 restraint segment 48 on second housing 52', the pressure applied by restraint

249 segment 48 compresses first clip member 18 into a bent position toward the first

250 surface of the spring clip 12. With first clip member 18 maintained in a bent

251 position under restraint segment 48, the second housing 52' is slidably

252 removable with the first housing 52 from the opening in enclosure 84 (see Fig.

253 8c). Detachment of each spring clip 12, 12' from first housing 52 is possible but

254 not required for an operator to remove first housing 52 and second housing 52'

255 from enclosure 84. For detachment of each spring clip 12, 12' from housing 52

256 for maintenance or replacement of a spring clip 12, the operator maintains

257 compression on each actuator member 44, maintaining each clip member 28 in a

258 bent position for passage of first insertion end 14 through opening 68. When

259 housings 52, 52' are disconnected from enclosure 84, each fiber optic cable 80

260 and/or 82 are available for maintenance by the operator without requiring access

261 by the operator to the interior portion of enclosure 84. Each one of the pair of

262 spring clips 12, 12' may be reinserted into respective connector groove 62, 64 for

263 releasably mating the housings 52, 52' together and for reinsertion through a

264 similar configured opening of an enclosure 84.

265 [0033] The preferred embodiment includes a first fiber optic cable end 80

266 connectable into the first distal end 54 of a first housing 52, and a second fiber

267 optic cable 82 connectable into the first distal end 54' of a second housing 52', to

268 allow transmission of optically transmitted information along the interior conduit

269 66 within the first housing 52 and the second housing 52' (see Fig. 7). It will be

270 understood by those skilled in the art that the interior conduit 66 or a similar 271 configured ferrule may be utilized for support of the end of a second fiber optic

272 cable 82 (Fig. 7) for alignment with the end of the first fiber optic cable 80 such

273 that optical fiber communication is established and maintained between the two

274 cables 80, 82.

275 [0034] An alternative embodiment of the spring member 140 is illustrated

276 in Figure 4c. Spring member 140 is formed as an articulated triangular arm

277 assembly extension of the spring member second end 16 (see Fig. 4c). The spring

278 member 140 may be composed of a material such as spring steel or another

279 resilient material that is flexible and repetitively returns to an original position

280 after manipulation. The spring member 140 includes a cantilevered end 142

281 biased in a position proximate an upper surface of the second clip member 28 at

282 about the second bend 34 portion. The cantilevered end 142 is biased against

283 the upper surface of the second clip member 28 by applied pressure against an

284 actuator side 144 and/or an end of the spring member 140.

285 [0035] From the foregoing description, it will be recognized by those skilled

286 in the art that a spring clip and connector housing is provided offering

287 advantages over the prior art (see Fig. 6), for releasably mating a pair of

288 connector housing components with an opening through an enclosure to which

289 an operator seeks to connect at least one fiber optic cable thereto. Specifically,

290 the spring clip 12 and connector housing 52 provides an efficient mechanism for

291 connecting one or more housings together, and connecting one housing into an

292 opening in an enclosure without having to access the interior of the enclosure in

293 which the connector housings are mounted. Accordingly, the spring clip and

294 associated connector housing provides for expedient removal of the housing

295 having a fiber optic cable connected thereto, for repair, cleaning, and/or

296 changing of the fiber optic cable ends connected to the housing. Moreover, it will

297 be recognized that the integral construction of the spring clip 12 having at least

298 two clip members 18, 28 and a spring member 40 formed thereon, simplifies

299 manufacturing and reduces manufacturing costs of the spring clip 12.

300 [0036] While numerous embodiments are illustrated and described, it will

301 be recognized that alternative embodiments of the disclosed invention may be

302 employed without departing from the spirit and the scope of the invention as set

303 forth in the appended claims. Further, the disclosed invention is intended to 304 cover all modifications and alternate methods falling within the spirit and the

305 scope of the invention as set forth in the appended claims.
