POGO PIN connector is mainly composed of 6 parts, namely needle shaft, spring, ceramic bead, needle tube, plastic, cap (basic customer's installation requirements can be equipped with plastic CAP to protect the needle shaft). Let's take a look at the form requirements of the contact terminal of the POGO PIN connector.
1. Design requirements for the end of the contact:
is a non-standard type of contact, designed according to the cable requirements of the complete machine, first confirm the size of the plug-in end, the product installation form, the appearance mode and the cable specification. When the cable cannot be determined, the principle to follow is to design the wiring hole according to the contact part number. The wiring hole can meet the requirements of large wire gauge wires. The ratio of the diameter of the core wire of the wire to the inner diameter of the welding cup is usually 0.5-0.7 ; When connecting a wire, the design principle is that the diameter of the cable core and the connection hole of the contact is appropriate, and the ratio of the diameter of the wire core to the inner diameter of the welding hole is usually 0.6-0.8.
2. Requirements for the form of the end of the contact:
In the POGO PIN connector, the contact is an important part of the connector, which mainly carries the signal transmission. In the design of the connector, the contact is composed of the mating end and the tail end. The mating end is usually composed of elastic parts and rigid parts to ensure the reliability of the contact between the connector plug and the socket; the tail end of the contact is to realize the cable connection between the equipment, the interconnection between the printed boards or the cable and The interconnection between boards is used for cable connection. The terminal end of the connector has welding wire type, crimping wire type, and insulation piercing type (IDC, solderless winding type, used for printed boards, contacts Termination forms include straight welding, bending welding, surface mount and welding-free press-in type.
