Abstract

A connector (10) for connecting an electrical conductor to an electrical terminal in which two integrally formed shank portions (12, 14) extend at an angle to each other. One shank portion (12) is adapted to extend in a terminal and the other shank portion (14) is adapted for connection to a conductor and extends downwardly from the first shank portion to minimize stress on the latter connection. A notch (16) is formed in the one shank portion to secure the connector in the terminal.

Description

ELECTRICA PIN WITH BEND
Background of the Invention
This invention relates to an electrical connector, and more particularly to a pin-type connector for making an electrical connection between a conductor attached to the connector and a corresponding electrical terminal.
The terminals on many electronic components use a spring-loaded clip, or clasp, which, when pushed, exposes an opening for receiving an electrical conductor. Upon release the spring-loaded clasp engages the conductor to establish an electrical connection between the conductor and the ter¬ minal. Pin connectors are often crimped or soldered to the conductor in order to facilitate the connection between the conductor and the terminal. However, the connection is such that the pin extends substantially horizontally and the
weight of the conductor thus creates a lever arm which puts stress on the crimped or soldered connection and thus compromises the integrity of the connection. Also, the outer coating of the pin is usually of gold, copper, brass, or other material having a relatively low coefficient of friction which can cause the pin to slip out of the spring- loaded terminal. -
Summary of the Invention
It is therefore an object of the present invention to provide a connector pin for attachment to an electrical con¬ ductor for establishing an electrical connection between the conductor and a spring-loaded terminal.
It is a further object of the present invention to pro¬ vide a pin of the above type which is designed to minimize stress on the connection between the conductor and the pin.
It is still further object of the present invention to provide a" pin of the above type in which slippage of the pin relative to the spring loaded terminal is eliminated.
Toward the fulfillment of these and other objects, the pin connector of the present invention includes a first shank portion adapted to extend in a sDring-loaded terminal
and a second shank portion extending from said first shank portion and at an angle to said first shank portion. The free end of the second shank portion is adapted for connec¬ tion to a conductor.
Brief Description of the Drawings
The above brief description as well as further objects, features and advantages of the present invention will be more fully appreciated by reference to the following detailed description of presently preferred but nonetheless illustrative embodiments in accordance with the present invention when taken in conjunction with the accompanying drawings wherein:
FIG. 1 is an enlarged perspective view of the connector pin of the present invention;
FIG. 2 is a front elevational view of the pin of FIG. 1;
FIG.' 3 is a sectional view taken along the lines 3-3 of FIG. 2; and
FIG. 4 is a partial side elevational view of the pin of FIG. 2.
Description of the Preferred Embodiment Referring to the drawings, the reference numeral 10 refers, in general, to the pin connector of the present invention. The connector 10 is formed by two shank portions 12 and 14 extending integrally to each other and fabricated of an electrical current conducting material, such as copper, brass, or copper or brass-plated metal. As shown in FIG. 2, the shank portion 12 extends substantially horizon¬ tally in use, as will be described, and the shank portion 14 extends downwardly at an angle A to the shank portion 12. According to a preferred embodiment the angle A is approxi¬ mately 60°.
Each shank portion 12 and 14 has a sguare cross section and a notch 16 is formed around the outer perimeter of the shank"portion 12 near its free end for reasons that will be described.
A crimping barrel, or sleeve, 18 extends over the free end portion of the shank portion 14 and is attached thereto in any conventional manner such as by soldering, or the like.
The sleeve 18 is formed by a strip of material, pre¬ ferably of the same type as the shank portions 12 and 14, which is bent into a circular configuration with the corresponding edge portions of the strip nearly in abut¬ ment. The edge portions have serrations 20 formed thereon to engage the conductor during crimping.
Prior to use, the conductor (not shown) is stripped of insulation at one end portion and the latter placed in the sleeve 18. The sleeve 18 is then crimped over the stripped conductor portion by a pair of pliers, or the like, to secure the conductor in the sleeve 18.
The connector 10 of the present invention is especially adapted for use with a terminal (not shown) of the type having an opening for receiving a conductor, or a pin type connector which is connected to the conductor. . This type of terminal includes a spring-loaded button which is pushed to move a plate to expose the opening. The connector 10 of the present invention can be used with this tyoe of terminal by simply inserting the shank portion 12 into the above- mentioned opening and releasing the spring-loaded push but-
ton so that the plate extends in the notch 16 to insure that the connector 10 will not slip out of the terminal.
The angular disposition of the shank portion 14 relative to the shank portion 12 enables the latter to extend hori¬ zontally into the spring-loaded terminal and the former to extend downwardly at an angle to the horizontal as shown in FIG. 2. This eliminates the lever arm which would otherwise be created if a straight pin was used and thus minimizes the stress on the connection between the conductor and the sleeve 18.
Thus the connector 10 of the present invention provides an electrical connection between a conductor and a terminal in a simple, quick and efficient manner.
It is understood that variations may be made in the foregoing without departing from the scope of the invention. For example, the sleeve 18 can be eliminated and the stripped conductor can be soldered directly to the end of the shank portion 14. Also, the pin connector of the pre¬ sent invention can be used with other types of terminals such as, for example, a terminal formed by a binding post having an opening therethrough for receiving the pin, and a
nut in threaded engagement with the post for securing the connection. Further, the angle A can be varied without departing from the scope of the invention.
Other modifications, changes and substitutions are intended in the foregoing disclosure and, in some instances, some features of the invention can be employed without a corresponding use of other features. Accordingly, it is appropriate that the appended claims be construed broadly and in a manner consistent with the scope of the invention therein.
