Wireless double-end probe function tester

Abstract

The invention discloses a wireless double-end probe function tester comprising a base, a support, a TP screen body for testing and a group of double-end probes electrically connected and matched with an FPC to be tested. The base comprises a top plate and a bottom plate, wherein the top plate and the bottom plate are in positioning fixation connection through a plurality of supporting pillars. With the usage direction being as the reference, one end of the support is fixedly arranged on the upper surface of the top plate; the side portion at other end is fixedly connected with a first positioning mechanism, wherein the first positioning mechanism is capable of positioning and breaking away from the FPC to be tested on the upper surface of the top plate; the top plate is further provided with a second positioning mechanism, wherein the second positioning mechanism is capable of positioning and breaking away from the TP screen body for testing on the lower surface of the top plate; the probes are positioned and fixed on the top plate; and one end of each probe is electrical connected with the FPC to be tested, and the other end of each probe is electrical connected with the TP screen body for testing. The wireless double-end probe function tester has the advantages of being simple in structure, being convenient to operate, and being capable of saving resources and preventing the electromagnetic interference among wires from influencing test results and the like.

Description

technical field [0001] The invention relates to a function tester, in particular to a wireless double-headed probe function tester. Background technique [0002] With the continuous development and innovation of science and technology, flexible circuit boards, referred to as soft boards or FPCs, have been greatly developed in the field of electronic products due to their advantages of light weight, ultra-thinness and flexibility. After FPC products are made , electrical performance testing is required, and TP screens are usually used to test the electrical performance of FPC products. The functional test fixture for testing FPCs usually includes a base, a bracket, a positioning mechanism for the FPC to be tested, and a connection between the FPC and the TP screen for testing. Probes, however, the commonly used probes are single-headed probes. When connecting the FPC and the TP screen for testing, the probe is fixed on the base, one end of the probe is electrically connected ...

[0002] With the continuous development and innovation of science and technology, flexible circuit boards, referred to as soft boards or FPCs, have been greatly developed in the field of electronic products due to their advantages of light weight, ultra-thinness and flexibility. After FPC products are made , electrical performance testing is required, and TP screens are usually used to test the electrical performance of FPC products. The functional test fixture for testing FPCs usually includes a base, a bracket, a positioning mechanism for the FPC to be tested, and a connection between the FPC and the TP screen for testing. Probes, however, the commonly used probes are single-headed probes. When connecting the FPC and the TP screen for testing, the probe is fixed on the base, one end of the probe is electrically connected to the FPC to be tested, and the other end of the probe is Connect one end of the wire, the other end of the wire is connected to another probe, and then the probe of the other probe is electrically connected to the TP screen for testing. This filtering connection method increases the production cost and wastes a lot of wires. Moreover, due to the introduction of multiple wires during the test, electromagnetic interference is easily formed between the wires, which affects and interferes with the test results.
