Floating type DB serial port socket connector

Abstract

The invention discloses a floating type DB serial port socket connector which comprises a shell, a base and a contact piece; wherein the shell comprises an upper shell and a lower shell; the base comprises an upper base and a lower base; a plurality of inserting holes are formed in the upper base, and a plurality of contact piece mounting holes which are communicated with the inserting holes in one-to-one correspondence are formed in the lower base; the upper base is fixedly connected with the upper shell, the lower shell is clamped and connected with the periphery of one end of the lower base; the upper shell and the lower shell are in butt joint and fixedly connected to form a base accommodating portion, so that the contact piece mounting holes in the upper base and the lower base can becommunicated with each other, and the lower base and the lower shell can move relative to each other; the contact piece comprises a first contact part which is fixed in the inserting holes of the upper base, and a second contact part which is fixed in the contact piece mounting holes of the lower base. The first contact part and the second contact part are electrically connected through an elastic arm. The floating of a floating electric connector can be realized, and the problem of unreliable contact caused by insufficient installation accuracy of electronic components can be avoided.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to a floating DB serial socket connector. Background technique [0002] With the development of electronic component technology, the size of electronic components tends to be more and more miniaturized and modularized, which puts forward higher requirements for the reliable installation of connectors. For signal transmission electrical connectors, the density is often higher, which can save space and concentrate on signal transmission. In addition, modular signal transmission electronic components transmit signals from the outside to designated modules. Due to the difficulty of precise installation and use due to the installation space and dimensional accuracy between modules, they often need to be designed as electrical connectors with floating functions to achieve tolerance installation. Require. [0003] Existing conventional signal transmission connectors, in ord...

AI Technical Summary

Problems solved by technology

[0003] Existing conventional signal transmission connectors, in order to achieve high-density transmission and meet electrical performance requirements at the same time, are often installed in a large size and occupy a large space, especially in an environment where the space is small and the installation location is limited; on the other hand, for To ensure reliable connection and transmission of signals, electrical connectors and their contacts are often relatively fixed, unable to float, and floating cannot be realized. The impact on modular signal transmission components that cannot be precisely installed is more obvious
