Problems solved by technology

Traditional modular connectors are mostly of pin welding type. In the process of soldering the connectors on the PCB board, due to objective factors such as the large number of connectors on the PCB board, the variety of types, and the number of cores, the design of the fixture used for welding more complicated
And the welding process, yield rate, etc. all directly affect the product cost
Due to the loss of the self-centering function of the contact body after soldering, the butt joint force of the product is large, and the yield of the product is considerably affected

Abstract

The invention discloses a tail elastic contact connector for PCBs (printed circuit boards). The tail elastic contact connector comprises an outer shell (1), a mounting support (2), an insulator (3), a sealing gasket (4), a contact body (5), a spring (6), a contact spring (7) and a contact body elastic contact end (8), the insulator (3) is fixedly connected in the outer shell (1) through the mounting support (2), the contact body (5) and the contact body elastic contact end (8) form an elastic contact body through the spring (6) and the contact spring (7), and the elastic contact body is mounted in the insulator (3). According to the tail elastic contact connector, tail elastic contact connector of the contact body replaces a traditional welding contact body, additional welding processes are omitted in the mounting process of the connector, and the connector has the advantages that the contact body reliably contacts with the PCB, so that the connector is mounted once without a fixture and high in reliability.

Description

technical field [0001] The invention relates to the technical field of structural design and application of connectors, and in particular provides a tail spring-contact connector for a PCB board. Background technique [0002] With the rapid development of electrical information integration, the electrical connection methods used in high-speed railways and intercity trains have developed from cable connection to PCB board integration. Traditional modular connectors are mostly of pin welding type. In the process of soldering the connectors on the PCB board, due to objective factors such as the large number of connectors on the PCB board, the variety of types, and the number of cores, the design of the fixture used for welding more complicated. Moreover, the welding process and yield rate directly affect the product cost. Due to the loss of the self-centering function of the contact body after soldering, the butt joint force of the product is large, and the yield of the produ...
