High current connector shrapnel micro pin module has obvious advantages
BTB connector is used for the two PCBs of the connector to realize mechanical and electrical connection. It is characterized by the matching use of female connector, so the plastic body and terminal of the connector have strict matching requirements.
As the largest connector Market in the world, BTB connectors are widely used in the field of mobile phones, mainly for the testing of mobile phone LCD, OLED screen, 3C lithium battery and camera.
At present, various consumer electronic products using connectors have integrated miniaturization, thinness and high performance. The corresponding connectors are becoming shorter and the connecting parts are becoming narrower.
According to the characteristics of small spacing and large current of BTB connectors, some manufacturers have developed them large current The shrapnel micro needle module adopts high-precision mold opening and standardized test module, which subverts the multi-component structure of the traditional probe module and adopts the integrated shrapnel structure. The minimum pitch value that can be adapted in the small pitch field can reach 0.15mm, with stable performance and outstanding performance.
large current The shrapnel microneedle module is made of nickel alloy / beryllium copper, with high precision, wear resistance and wear resistance. For high current BTB test items, the rated current is 3a, and the maximum constant current test can withstand 50A. During the test, the current is concentrated in the same material, the resistance is constant, the electrical property is stable, and there is almost no current attenuation.
large current The shrapnel microneedle module is not only outstanding in the test of high current and small spacing, but also has a unique response to the test of the mother seat of BTB connector. During the test, the male and female seats of BTB connector are tested with shrapnel of different head types. The sawtooth type is used for BTB male seat test, and the tip type is used for BTB female seat test.
BTB seat test: the sawtooth shrapnel contacts the shrapnel on the top of BTB connector. During the test, the shrapnel of microneedle module contacts the shrapnel on the top of BTB connector at multiple points to ensure contact stability. During the mother seat test: the sharp tip spring piece head is inserted between the spring piece openings in the BTB connector, resulting in a certain opening amount for the BTB connector spring piece, and the contact surface of the micro pin module spring piece is always in contact with both sides of the BTB connector spring piece.
large current The head of the shrapnel microneedle module is designed to be self-cleaning without manual maintenance, which can ensure the long-term stability of the test and reduce the test cost. The integrated shrapnel structure has the characteristics of low processing difficulty coefficient, short production cycle and fast delivery time, which greatly improves the test efficiency of BTB connector. Should large current The shrapnel micro pin module is generated to adapt to the BTB connector. It has a stable connection function and has been perfectly handled in the tests of small pitch, high current and male and female seats.
