TESTING APPARATUS FOR TESTING ELECTRICAL CIRCUIT BOARD HAVING ELECTRICAL CONNECTORS THEREON

摘要

A testing apparatus for testing a circuit board is disclosed, which includes an upper plate, a lower plate, and an adaptor circuit board. A plurality of positioning units is received in the lower plate. Each positioning unit has a plurality of length-variable test probes secured therein. Each test probe has a shell and upper and lower probe ends at opposite ends of the shell. In test, the circuit board is put on the lower plate and the upper plate is lowered to push the circuit board and the lower plate toward the adaptor circuit board. The upper ends of the test probes engage with electrical connectors of the circuit board and the lower ends thereof engage with the adaptor circuit board whereby test of the circuit board can be automatically performed by the testing apparatus.

主权项

1. A testing apparatus for testing an electrical circuit board having at least one electrical connector thereon, comprising:
an adaptor circuit board configured to transmit electrical signals between the testing apparatus and the electrical circuit board; a lower plate defining a plurality of voids therethrough; a plurality of positioning units each having at least one test probe fixed therein received in a corresponding void of the lower plate; and an upper plate vertically movable relative to the lower plate; wherein when the electrical circuit board is mounted on the lower plate, the upper plate moves downwardly to press the electrical circuit board and the lower plate toward the adaptor circuit board to cause the at least one test probe to electrically engage the adaptor circuit board and the at least one electrical connector.
