ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to an electrical contact, and more particularly to an electrical contact having two spring arms for respectively and electrically connecting two elements. The displacements of the spring arms are orthogonal to each other.
DESCRIPTION OF THE PRIOR ART
There are a variety of electrical contacts for use with a variety of electrical connectors for different field applications. In general, an electrical contact includes a body portion, a spring arm, and a solder tail. The body portion is usually and securely embedded in a housing of the connector thereby attaching the electrical contact to the housing. The spring arm generally extends into a passageway for electrically connecting with a complementary contact of a mated connector. The solder tail is either soldered to a printed circuit board or a conductive wire of a cable. This electrical contact can be referred to as a single-beam contact. Some of the electrical contacts are formed with dual-beam in which a complimentary contact is sandwiched between the dual-beam type spring arms. Among the single-beam and the dual-beam contacts, both the spring arms, body portion and the solder tail are located in a same plane.
U.S. Pat. Nos. 4,770,180 and 5,102,353 disclose a dual-beam type contact and which extend from a body portion thereof. The spring arms extend upward and downward respectively to defining a space therebetween for receiving a complementary contact. Even the spring arms are offset from each other, the spring arms extend from the same side of the contact.
SUMMARY OF THE INVENTION
An objective of this invention is to provide an electrical contact having two spring arms for respectively and electrically connecting two elements which are located in two planes which are orthogonal to each other. The displacements of the spring arms are orthogonal to each other.
Another objective of this invention is to provide an electrical contact with two springs of different Young's modulus.
In order to achieve the objectives set forth, an electrical contact for bridging a first device to a second device which is movably positioned respect to the first device, comprises a body portion for securely mounting to a supporting frame. A first spring arm extends from an end of the body portion for selectively and electrically contacting the first device. The first spring arm forms a first contacting end. A second spring arm extends from the other end of the body portion for permanently and electrically contacting the second device. The second spring arm forms a second contacting end. When the second device is positioned at a first position, the first and second devices are electrically disconnected, and when the second device is positioned at a second position, the first and second devices are electrically connected.
These and additional objects, features, and advantages of the present invention will become apparent after reading the following detailed description of the preferred embodiment of the invention taken in conjunction with the appended drawings.
