Abstract

The invention discloses a cantilever needle module for testing a small-spacing connector, which comprises a mounting seat, a plurality of cantilever needles, a matching seat, a probe fixing assembly, a limiting nail and a spring, and is characterized in that the matching seat is provided with a top protection groove, and each cantilever needle comprises a first connection section, a middle connection section and a second connection section used for being in contact test with a connector contact; the two ends of the middle connecting section are connected with the first connecting section and the second connecting section respectively; the first connecting sections of the cantilever needles are fixed to the probe fixing assembly, the second connecting sections are located above the top protection groove or in the top protection groove, the limiting nail penetrates through the mounting base, and the spring is located on the lower side of the mounting base. The mode that the second connecting section of the cantilever needle is in contact with the connector contact for testing is adopted, contact conduction is achieved, meanwhile, two probes can be in contact with one contact of the connector, and the problems that the test reject ratio is high, and frequent maintenance is needed are solved. In an actual test, the connector can be pressed down along the upper part of the matching seat.

Description

technical field [0001] The invention relates to the field of connector testing, in particular to a cantilever needle module for testing micro-spacing connectors. Background technique [0002] At present, after the connector is soldered to the FPC, it is necessary to perform a 4-wire accurate resistance test. Two probes need to be placed on the top of the connector, and two probes are placed on the PAD at the other end, forming a 4-wire loop. Test the connector to The precision resistance of PAD determines whether the soldering condition of the connector is good. [0003] However, existing connector tests suffer from the following flaws: [0004] Since the existing technology cannot place two probes on the top of the connector, one probe is placed on the top and one is placed on the solder leg. Since there is solder and flux on the solder feet, the probe on the solder feet adheres to the flux, and the contact is poor, and the flux and solder will block the probe hole, so th...
