1. Field of the Invention
The present invention relates to an electrical contact, and especially to an electrical contact used in an electrical connector for electrically connecting an integrated circuit (IC) to a printed circuit board (PCB).
2. Description of the Prior Art
The first arm 21 and the second arm 22 symmetrically extend transversely from the base 20, which makes the distance between any two adjacent electrical contacts along the metal strip (shown in
Hence an improved electrical contact is desired to overcome the disadvantage of the related prior art.
An object of the present invention is to provide an electrical contact in an unsymmetrical structure, so that the distance between two adjacent contacts along a metal strip decreases.
An electrical contact of an electrical connector in accordance with the present invention comprises a board-like base, a first arm extending from a side of the base, and a second arm extending from an opposite side of the base. The first arm winds forwardly and ends with a first contacting portion having a bottom face, while the second arm winds forwardly and ends with a second contacting portion having a top face, wherein when said electrical contact is unwrapped, said bottom face of the first contacting portion is no lower than said top face of the second contacting portion in a vertical direction.
Other objects, advantages and novel features of the present invention will become more apparent from the following detailed description of the present embodiment when taken in conjunction with the accompanying drawings.
Referring to
The semi-finished contact 4 has the same configuration as the semi-finished contact 3 and is disposed by the right side of the semi-finished contact 3. The semi-finished contact 4 comprises corresponding first arm 44 and the first arm 44 ends with a first end 441 defining a bottom face 4411. The bottom face 4411 of the first free end 441 of the semi-finished contact 4 is located above the top face 3511 of the second free end 351 of the adjacent semi-finished contact 3. The first free end 441 of the semi-finished contact 4 is disposed staggeringly with respect to the second free end 351 of the semi-finished contact 3.
When the semi-finished contact 3 is formed into the electrical contact 1, the first arm 34 and the second arm 35 are bent forwardly and circuitously. The first free end 341 and the second free end 351 are bent perpendicularly to the base 31 so that the first contacting portion 141 and the second contacting portion 151 are formed. The solder portion 33 is bent perpendicularly to the base 31 for later soldering the contact 1 to the PCB. When the semi-finished contact 3 is finally cut from the carrier strip 10, an electrical contact 1 is formed.
It is to be understood, however, further though numerous, characteristics and advantages of the present invention have been set fourth in the foregoing description, together with details of the structure and function of the invention, the disclosed is illustrative only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent identify by the broad general meaning of the terms in which the appended claims are expressed.
