The present invention relates to a socket, and more particularly to a signal line socket adapted to a test circuit board.
Along with electronic industry development, the circuit design of electronic product becomes more complicated. For assuring the function of produced circuit has the same function as the original design one, it is important to have an accurate test fixture of circuit board to achieve the fast testing.
Generally, the testing method is as the following. First of all, plural test points of a tested circuit board are connected to a plural of signal lines, respectively. Subsequently, the signal lines are inserted into a signal line socket of a test circuit board for electrically connecting the signal lines to the test circuit board and transferring the signal from the tested circuit board to the test circuit board. Then, the test is performed to determine whether the tested circuit board is operated normally or not.

Certainly, the signal line socket 11 can achieve the electrical connection function between the signal line 13 and the test circuit board 12. However, the operator has to push the buttons 112 of the signal line socket 11 to relieve the signal lines 13 one by one after testing. It causes operation inconveniently, especially when the tested circuit board needs to be connected to more than one set signal lines for testing. Since it is time consumption, the yield is hard to be increased. In addition, the structure design of the buttons 112 and the receiving elements of the signal line socket 11 must appropriately cooperate each other for smoothly inserting and relieving the signal lines 13. It is not only complicated structure and difficult assembly but also higher cost.
