ELECTRICAL CONNECTORS This is a continuation of application Ser. No. 653,419, filed July 14, 1967.
This invention relates to electrical connectors and more particularly to electrical connectors for use in connection with panels such as, for example, printed circuit boards.
In U.S. Pat. No. 3,075,167, a printed circuit connector is disclosed which includes parallel legs extending outwardly from a web portion in a cantilever manner. The legs are disposed in a plane containing the web portion and the free ends of the legs are provided with inwardly-directed contact sections, also in the same plane as the legs and web portion. 'lhese contact sections are for engagement with conductive paths of a printed circuit board, but that they contain sharp edges which increases the wear on the conductive paths in addition to causing abrasion to the paths if they are plated with precious metals.
U.S. Pat. No. 2,926,328 discloses a printed circuit connector which comprises parallel leg members extending outwardly from one end of a body portion at one side as opposed requires a lot of metal to make and the legs are too flexible to provide positive contact. A similar connector is described in U.S. Pat. No. 2,853,689.
An object of the present invention is to provide an electrical connector with cantilever legs provided with large area contact sections at the free ends from thin-rolled stock.
Another object of the invention is the provision of an electrical connector having stabilizing means to maintain the contact sections in position in channels of a passageway of a housing.
A further object is to provide an electrical connector that has smooth contoured contact surfaces for positive contact with mating contact surfaces which reduces contact surface wear and increases contact life.
An additional object is the provision of an electrical connector having cantilevered fork contacts with beams providing equal distribution of contact forces and torquing of the cantilever beams permitting the contact areas to adjust to the surface configuration of the mating contact surfaces.
Other objects and attainments of the present invention will become apparent to those skilled in the art upon a reading of the following detailed description when taken in conjunction with the drawings in which there are shown and described illustrative embodiments of the invention; it is to be understood, however, that these embodiments are not intended to be exhaustive nor limiting of the invention but are given for purposes of illustration in order that others skilled in the art may fully understand the invention and the principles thereof and the manner of applying it in practical use so that they may modify it in various forms, each as may be best suited to the conditions of a particular use.
The invention is directed to an electrical connector which comprises a planar body section having cantilever legs extending outwardly therefrom and disposed in the same plane as the body section. Free ends of the legs have contacts disposed substantially at right angles with respect to the plane of the legs and body section. The contacts have contact surfaces at least three times the thickness of the legs and they are arcuateshaped in a fore-and-aft direction as well as in cross section.
In the drawings:
FIG. 1 is a perspective exploded, view of a dielectric housing I with a passageway in cross section and an electrical connector exploded therefrom;
FIG. 2 is a cross-sectional view through a passageway of the housing of FIG. 1 with an electrical connector in position therein;
FIG. 3 is a view taken along lines 3-3 of FIG. 2;
FIG. 4 is a view taken along lines 4-4 of FIG. 2 showing the configuration of the contact sections;
FIG. 5 is a side elevational view of an embodiment of the electrical connector;
FIG. 6 is atop plan view ofFIG. 5;
FIG. 7 is an exploded plan view of a ferrule member and a wire to be crirnped therein;
FIG. 8 is a view similar to FIG. 7 with the wire crirnped in position in the ferrule member;
FIG. 9 is a view taken along lines 9-9 of FIG. 8; and
FIG. 10 is a view taken along lines 10-10 of FIG. 9.
Turning now to the drawings and more particularly to FIGS. 1 through 4, a part of a dielectric housing H is illustrated which is provided with passageways 11 for receiving electrical connectors EC. Passageways l are in communication with channel 2 in whicha printed circuit board is to be received. Each of passageways 1 includes projections 3 in opposing surfaces and depressions 4 in other opposing surfaces.
Electrical connector EC comprises a contact section 5 and a ferrule section 6. Contact section 5 includes a body portion 7 provided with extensions 8 along opposing sides thereof. An arcuate stop 9 is struck out from body portion 7 in about the central portion thereof. Stop 9 is directed in the same direction as extensions 8. Extending outwardly from the front end of body portion 7 is a spring lance 10 which is bent back over body portion 7 in overlying relationship with respect to stop 9. Spring lance 10 has a wedge-shaped configuration as illustrated in FIG. 2. Body portion 7 and extensions 8 fit snugly within the rear section of passageway l with extensions 8 engaging projections 3 in passageway 1 to limit the movement of the electrical connector within the passageway and spring lance 10 seats in one of depressions 4 to limit movement of the electrical connector out of the passageway. Arcuate stop 9 prevents spring lance 10 from being permanently set so as not to be operable. With depressions 4 being disposed in opposing surfaces of passageway l, the electrical connector can be inserted in the passageway in more than one direction and still be operable.
Turning now to FIGS. 5 and 6, electrical connector ECa is illustrated which is an embodiment of electrical connector EC. Body portion 7 is provided with a projection to permit the electrical connector to be force-fitted into a passageway of a housing member with post 16 extending outwardly from the rear surface of the housing and the ends of body portion 7' adjacent post 16 engaging the inner end of the passageway to limit movement of the connector thereinto. Post 16 could be a ferrule section such as ferrule section 6. As can be discerned, cantilever legs 11' are provided with bent sections 17 along the area of contacts 12' so that contacts 12' are disposed centrally of cantilever legs 1 1 to distribute the loading of the contacts on the conductive paths of the printed circuit board about the center line of the electrical connector.
FIGS. 7 through 10 illustrate ferrule section 6 of electrical connector EC but of course this ferrule section can be used in conjunction with any other type of electrical connector in which electrical wire is to be crimped. Ferrule section 6 includes a wire-engaging portion 18 for crimpably engaging the conductive portion of wire 19 and an insulation-engaging portion 20 for engaging the insulation of wire 19 to provide strain relief therebetween. Wire-engaging portion 18 is U-shaped in cross section and has chevron-shaped depressions or serrations 21 formed therein. Serrations 21 permit the strands of wire or solid wire to be extruded thereinto upon crimping pressure being applied to wire-engaging portion 18 thereby providing staggered interruptions in the wire in an axial direction along wire-engaging portion 18 instead of in planes normal to the axis of the wire-engaging portion in accordance with conventional practice as illustrated in US. Pat. No. 2,800,638. The crimp performed by the chevron-shaped serrations does not therefore fatigue the metal and does increase the tensile to provide a more desirable and effective crimp; corrosion resistance is improved and conductivity in the connection is more stable.
It will, therefore, be appreciated that the aforementioned and other desirable objects have been achieved; however, it should be emphasized that the particular embodiments of the invention, which are shown and described herein, are intended as merely illustrative and not as restrictive of the invention.
