J30J series micro rectangular electrical connectorDetailed product description：

The J30J series micro rectangular electrical connector complies with GJB2446 "General Specification for Shell Positioning Ultra small Rectangular Electrical Connectors" (equivalent to the US military standard MIL-C-83513), and can be interchanged with MDM series products in the United States and similar products in China. On the basis of the J30 series products, aluminum alloy shells and various aluminum alloy tail clips have been added; The twisted wire contact pin (commonly known as Fried Dough Twists pin) is adopted, and there are seven contact points of a single contact, which improves the contact reliability of the product; Adopting a 1.27mm grid, the contact density is high, the volume is small, and the weight is light; There are ten types of spectra available for selection, including 9, 15, 21, 25, 31, 37, 51, 66, 74, and 100 cores; The applicable cross-sectional area of the wire core is 0.07-0.15mm2, and the tail end can be wired according to user requirements; The locking components of this product are provided together with the product assembly. If the locking components are not required, please specify in the contract; This series of products meets the requirements of GJB2446 "General Specification for Shell Positioning Ultra small Rectangular Electrical Connectors"; The execution standards for this series of products are as follows: Q/ZHDZ GC-18 "Detailed Specification for J30J Series Micro Rectangular Electrical Connectors".
