Definitions
- one end of a member of U-shaped cross-section forms a trough receiving a contact unit and the opposite end is firmly connected to the handle, an intermediate portion being flexible and resilient.
- Means are provided for selective attachment of either type of tool bit to a common handle.
- This invention relates to a tool for use with electrical connectors and more particularly to a tool for insertion or withdrawal of fragile elongated contact units into or from passages in electrical connectors without damage to the contact units.
- the tool is relatively simple in construction and is rugged and durable while being easy to use.
- This invention was evolved with the general object of overcoming the disadvantages of prior art tools and of providing a tool with which contact units can be readily and easily inserted or withdrawn, without damage thereto.
- the invention is based in part upon the discovery that with prior types of tools, the difficulties in use and the damage to contact units has arisen because of the rigid support of the contact unit-engaging portion of tool bits from the handle. As a result, exact alignment has been required for insertion or withdrawal of the contact units and with any misalignment, bending or breaking of the contact units has resulted.
- flexible resilient means are provided in a tool bit in a manner such as to allow angulation of a handle while still obtaining the required alignment and while avoiding bending of the contact units.
- flexible resilient means are provided in the form of a member of elastomeric material which supports an end portion of an elongated member opposite to an end portion engaged with a contact unit.
- the member of elastomeric material is disposed within an opening in a support member and in surrounding relation to the elongated member.
- a ball bearing is disposed between an internal surface portion of the support member and a terminal end of the elongated member which preferably has an annular outward flare.
- the elongated member is a rigid tubular member and a sleeve of a relatively soft material is atfixed thereon to form a resilient stop.
- an elongated member has acontact-unit engaging portion at one end, an opposite end portion firmly supported and an intermediate portion which is flexible and resilient.
- the contact-engaging end portion may preferably have a generally U-shaped cross-sectional configuration to form a trough for receiving a contact unit.
- FIG. 1 is a side elevational view, partly in section, showing a tool constructed in accordance with the principles of this invention
- FIG. 2 is a cross-sectional view taken substantially along line II-II of FIG. 1;
- FIG. 3 is a cross-sectional view, on an enlarged scale, showing one form of tool bit, its connection to the tool handle and its use in withdrawal of a contact unit of an electrical connector;
- FIG. 4 is a side elevational view, partly in cross-section, illustrating a second form of tool bit
- FIG. 5 is a sectional view, on an enlarged scale, taken substantially along line VV of FIG. 4.
- the illustrated tool 10 comprises a handle 11 which includes a hollow body 12 of generally elliptical crosssection, with one end thereof being closed and with a portion 13 of a cap 14 being inserted into the opposite end.
- the portion 13 may preferably be formed with slots 15 to provide a certain degree of flexibility for frictional interengagement with the inside surface of the wall of the portion 12, while permitting withdrawal and reinsertion.
- the cap 14 further includes an enlarged central portion 16 and a cylindrical portion 17 which has a central portion to fixedly receive an externally threaded shank 18.
- the tool bit 20 includes a support member 21 which has an enlarged diameter portion 22 held against the end of the shank 18 by means of a nut 23 threaded on the shank 18 and having an inwardly facing shoulder engaging a shoulder defined by the outwardly facing annular surface of the enlarged diameter portion 22.
- the tool bit 20 further includes an elongated member 24 of tubular form having an end portion 25 adapted to receive a pin 26 of a contact unit 27 of an electrical connector.
- the illustrated contact unit 27 is a type of unit referred to as a filter pin and includes ferrule means of a ferrite material together with means defining capacitances, operative to filter out high frequency electrical components.
- the center of the central portion 28 is engaged by tines 29 of a ground plate 30 which is disposed between a pair of members 31 and 32 forming an insulating body of the electrical connector.
- a retaining sleeve 34 is provided which is slotted to define fingers 35 and 3 6 which resiliently engage a shoulder 37 of the unit 27.
- a seal member 38 is provided having an opening 39 through which the pin 26 projects.
- the member 24 is inserted onto the pin 26 and moved to the left as viewed in FIG. 3, the end portion 25 being preferably provided with a beveled terminal end 40 operative to spread the opening in the seal member 38.
- the unit 27 is moved to the left and the shoulder 37 is conically shaped to spread the fingers 35 and 36 by cam action.
- the beveled terminal end 40 operates to further spread the fingers 35 and 36 to allow movement of the contact unit 27 to the left. This operation is continued until a sleeve 44 on the member 24 engages the seal member 38, the member 44 thus forming a stop for limiting the movement of the contact unit.
- the unit 27 may be readily withdrawn by pulling it from the opposite side of the connector.
- the unit 27 particularly one of the filter pin type as illustrated, is fragile and can be readily damaged if subjected to bending, the ferrite and capacitance elements thereof being relatively brittle.
- the contact unit-engaging portion 25 is flexibly and resiliently supported from the handle 11.
- this flexible and resilient support is obtained by means of a member 45 of an elastomeric material such as soft rubber or preferably a synthetic material having elastomeric properties similar to those of soft rubber.
- the member 45 takes the form of a sleeve and is disposed in surrounding relation to an end portion 46 of the member 214 which is opposite the contact unit-engaging portion 25.
- Member 45 is disposed within an opening 47 in the support member 21. With the member 45, the member 24 can be readily aligned with the passages through the connector and the possibility of exerting bending forces on the unit 27 is minimized.
- a ball bearing 48 which is disposed between a terminal end 49 of the end portion 46 and an internal surface 50 of the support member 21.
- the terminal end 49 is of outwardly flared annular form and the surface 50 is of generally conical shape.
- FIG. 4 Another type of tool bit is shown in FIG. 4 and is designated by reference numeral 52.
- the tool bit 52 comprises an elongated member 53 having an end portion 54 for engaging a contact unit and having an opposite end portion 55 which is firmly supported within an opening 56 in a support member 57 and includes an enlarged diameter portion 60 similar to the portion 22 of the support member 21.
- the contact unit-engaging portion 54 preferably is of generally U-shaped cross-sectional configuration, as shown in FIG. 5, and provides a trough for supporting a contact unit for insertion into a passage of an electrical connector, the contact unit being disposed with the center of gravity thereof within the portion 54 to be held by gravity and by frictional engagement therein.
- an intermediate portion 61 of the member 53 is flexible and resilient.
- the member 53 and also the member 24 may be of stainless steel.
- the sleeve 58 and also the stop sleeve 44 may be of nylon or a similar material.
- Support members 21 and 57 may be of steel or other rigid material while the body 12, the cap 14 and the threaded shank 18 may be of a suitable relatively hard plastic.
- the tool bit 52 may be stored within the hollow body 12 when not in use and similarly the tool bit 20 may 'be stored therewithin when the tool 4 bit 52 is in use. When neither is being used, both may be stored within the hollow body 12.
