How to quickly select the J30J micro rectangular electrical connector

1. First of all, first understand the product itself, high-density, high reliability, small-sized products, the use of stranded flexible pin (twisted pin), wire cross-section suitable for 0.1mm2 ~ 0.15mm2, the minimum 0.07mm2 line. Meet the requirements of GJB2446, equivalent to the U.S. military standard MIL-DT-83513. 9 core-15 core-21 core-25 core-31 core-37 core-51 core-66 core-74 core-100 core micro-rectangular electrical connector specifications. Step to consider the product use environment, consider what material to choose, there are aluminum alloy, copper, stainless steel materials. Generally aluminum alloy nickel-plated, lightweight and bright.J30J-TJ/ZK fixed supporting the use of commonly used basic type.2. No problem with the material, consider the form of termination, is to use crimp or weld according to their own preferences, welding is a bit of a problem, welding technology to be skilled. Crimping is convenient and quick, to have crimping tools. Crimp type need not be expressed in letters, welding with S, in which to consider the printed board welding, there are two kinds, straight welding with N, W said 90 ° bent pin welding. Secondly, consider the connection between the cable and the cable, wire welding or crimping after the provisions of the length of the line, testing, marking to complete a complete set of assembly line. In order to prevent the welded wire is loose, you can consider the tail section with clamp line, there are straight and curved type, with A, belonging to the fast lock type, divided into A1,A2,A3 wire clamp. The direction of dumping the wire to increase the curved type wire clamp, equipped with a metal anti-wave sleeve, the same side of a wire outlet, the clamp plate and the shell with screws between the fixed. Indicated by the letters C and C1. Socket and plug on the plug, to prevent loosening, poor contact, the two sides also need to be screwed together, the socket is indicated by the P, the plug is indicated by the L, a variety of models, the size of the different sizes, (P1,P2,P25 ...) (P1, P2, P25... and L1, L7, L14...). Customers do not need to consider this aspect of the selection, as long as the size of the clear, the manufacturer will be supporting good. The size of the socket is not fixed, in addition to the basic type, exaggerated type J, there are special types of sockets 9.6, plug 11.6, with Q letters. After the shell and shell butt plug, to prevent screw rotation, in the shell flange mounting holes in the groove, indicated by the letter D. The last is the special socket requires sealing, the use of glass sintering process, good sealing performance, order with M said. The cost is high and the price is not low. Recently developed to adapt to the market some high-current hybrid electrical connectors, wire core cross-sectional area of 2.0mm2 ~ 3.0mm2 line of high-current, the development of the product has a 2-core ~ 9-core, each core of the large 20A, high-current jack S, high-current pin P said.
