Shenzhen connector manufacturers will explain to you what are the requirements for the terminal form of the connector contact 1. The design requirements for the contact end are non-standard contacts. Design according to the cable requirements of the whole machine. First determine the size of the mating end and product installation Form, appearance and cable specifications. When the cable cannot be determined, the principle is to design the wiring hole according to the contact part number. The wiring hole should be able to meet the requirements of the large wire gauge wire. The ratio of the diameter of the wire core to the inner diameter of the welding cup is generally 0.5-0.7; When connecting a wire, the design principle is to match the diameter of the cable core and the connection hole of the contact, and the ratio of the diameter of the wire core to the inner diameter of the welding hole is generally 0.6-0.8. 2. Contact end form
In the connector, the contact is an important part of the connector, which is mainly responsible for signal transmission. In the connector design, the contact is composed of two parts: the mating end and the tail end. The mating end is generally composed of elastic parts and rigid parts to ensure the reliability of the contact between the connector plug and the socket; the end of the contact is to realize the cable connection between the equipment, the interconnection between the printed boards or the cable and the board The interconnection between the connectors is used for cable connection. The terminal end of the connector has a welding wire type, a crimping wire type, and an insulation piercing type (IDC, solderless winding type, used on the printed board, the contact end The connection forms include straight welding, bending welding, surface mount and welding-free press-in type.
