ATTORNEY United States Patent 3,164,433 WIRING CONNECTOR Lester E. Adams, Oak Creek, Wis., assignor to General Motors Corporation, Detroit, Mich, a corporation of Delaware Filed Mar. 12, 1962, Ser. No. 179,071 6 Claims. (Cl. 339-258) This invention relates to spring wire connecting clips, and more particularly to a clip for electrically connecting an electrical conductor to an electric terminal post.
In the design, manufacture and use of many electrical components it is often necessary to temporarily connect an electrical conductor to an element. Under such circumstances it is desirable to have a connecting fastener which is simple to operate and inexpensive to obtain. For example, a typical element is provided with terminal posts, and it may be necessary to use such an element in a laboratory or other installation or to test the element under some conditions. It would be desirable to temporarily connect an electrical conduit to one of the terminal posts. In so doing it is most eflicient if the fastening device permits a quick connect and disconnect of the conductor with respect to the post but wh ch is positive in its retention and will conduct electricity properly.
There are many devices available permitting the quick connect and disconnect of conductors to terminal posts, most of which are extremely complicated and require a complicated means for securing the fastener to the terminal post. This wastes time and etfort of the operator and such fasteners are relatively expensive.
The device in which this invention is embodied comprises, generally, a connector clip having an extremity receivable over the terminal post and a bow portion which extends over the terminal post and is reversely bent to engage the terminal post and clamp the terminal post between the bow portion and the terminal post engaging extremity. The clip is resilient to permit the bow portion to bend at a point spaced from the terminal post so that such movement causes the locking member to move in an are out of engagement with the terminal post. Furthermore, the construction is such that the conductor cannot disengage the clip from the terminal post under ordinary conditions. The clip is extremely simple to operate and provides a fast connect and disconnect from the terminal post when desired. The connector clip is inexpensive to manufacture and provides a positive and efficient connector between a conductor and a terminal ost. P These and other advantages will become more apparent from the following description and drawing, in which:
FIGURE 1 is a view of an installation showing an electrical element with the connector clip secured in place;
FIGURE 2 is an enlarged view of a portion of the installation of FIGURE 1, illustrating more clearly the connection of the connector clip to the terminal post;
FIGURE 3 is an enlarged end view of a portion of the installation of FIGURE 1, illustrating the connection of the connector clip to the terminal post; and
FIGURE 4 is an isometric view of the connector clip illustrated in FIGURES 1-3.
Referring more particularly to the drawing, an electrical conductor is shown connected to an electrical element 12 by means of a spring wire connector clip, illustrated generally by the numeral 14. Element 12 is shown to include a pair of terminal posts 16 and 18 having enlarged flattened portions 20 and 22, respectively. Flattened portions 20 and 22 may be provided with some sort of wire engaging means, the preferable form being apertures 24 and 26, respectively. However, such means may be eliminated and the wires to be .connected thereto may be soldered. For illustration purposes, apertures 24 and 26 are shown.
Electrical conductor 10 is shown to include an electrically conducting wire 28 surrounded by suitable insulating material 36). Adjacent the connector clip 14 the insulation material 30 isstripped from the wire 28 to portion 21) of terminal post 16. This permits proper location of the connector clip 14 relative to the terminal post, as will become hereinafter more apparent. Following the U-shaped portion 38 a final reversely bent section 40 paralleling reversely bent portion 36 completes the extremity of shank 34.
Extending from the opposite end of shank 34, that is, the right-hand end as viewed in FIGURE 1, is a bow portion 42 extending over the shank 34 and arcuately downwardly toward the terminal post 16. Bow portion 42 terminates in a reversely bent section 44 which provides a lock arm adapted to engage the flattened portion 20 to seat in the aperture 24 if such aperture is provided.
It may be noted from viewing FIGURE 1 that bow portion 42 is bendable about the end of shank 34. It is also noted that the pivot or bend point is located in a plane above the plane containing the lock arm 44. As the bow portion 42 is lifted upwardly the lock arm 44 will travel in an arcuate direction, with the center of the are being at the pivot or bend juncture of the bow portion 42 and shank 34. This causes the lock arm 44 to move away from terminal post 24, that is, toward the left and upwardly as viewed in FIGURE 1, upon disengagement of the connector clip 14 from the transistor 12. Upon connection it is seen that the opposite result takes place and that the lock arm 44 travels downwardly and inwardly to snap into place in fitting engagement against the enlarged portion 20 or in aperture 24 if such is provided.
It mayalso be noted that a pull on the shank portion 34, as by the wire 28, will not disengage lock arm 44 from the terminal post 16. Such a pull will be translated directly tothe terminal post through the shank 34 and will not unseat the lock arm 44. An upward pull on shank 34 will cause the bow portion to are inwardly, more firmly seating the lock arm 44 in aperture 24, because of the engagement of lock arm 44 with the terminal post. Thus, it is necessary only to handle the bow portion 42 of the connector clip 14 for engagement or disengagement with the terminal post 16. The terminal post is clamped between the U-shaped portion 38 of the shank 34 and the lock arm 44 of the bow portion 42, providing the proper electrical connection and securely retaining the connector clip 14 on the terminal post 16. This creates an efiicient, quick connecting and disconnecting installation for use with terminal posts extending from electrical elements.
It is, of course, understood that the material of which the connector clip 14 is manufactured is a proper electrical conductor to convey electrical current from the wire 28 to the terminal post 16. Furthermore, if some insulation means is required, any portion of clip 14 may be suitably covered except for those sections engaging wire 28 and the terminal post 16.
