Problems solved by technology

The existing wire lead terminal for connecting the wire to the printed board has the following problems: the use range of the wire lead terminal is relatively narrow, and it cannot be applied to the wire with the shielding layer, because the wire lead terminal cannot protect the shielding layer. In addition, the existing wire lead terminal only relies on the conductive pin to bear the pulling force, so that the position of the conductive pin is easy to loose and cause signal transmission failure

Embodiment Construction

[0030] Examples of connecting components used to connect wires to printed boards are Figure 1~13 As shown: it includes a wire lead terminal 9 with a conductive pin 11 at the front end, and a wire hole for connecting with a wire at the rear end of the wire lead terminal. The connection assembly also includes a fixed sleeve 7. The fixed sleeve includes a sleeve-shaped body made of metal material whose axis extends along the front-to-back direction. It constitutes the shielding layer limiting surface with the blocking direction facing forward, and the front end of the sleeve-shaped body is arranged with four reinforced grounding pins 10 for welding with the printed board at intervals around the circumference. The inner hole of the sleeve-shaped body is guided from front to back with a shielding layer connection structure and an insulator 8. There are two wire lead terminals 9, and the wires 1 corresponding to the two wire lead terminals 9 are twisted pairs. The insulator is prov...

Abstract

The invention relates to a connection assembly for connecting a lead with a printed board and a fixing sleeve of the connection assembly. The connection assembly comprises lead terminals and the fixing sleeve, the front ends of the conductive pins include conductive pins respectively, the fixing sleeve comprises a sleeve-shaped body made of a metal material and extending along the front-and-back direction, the lead terminals are arranged in inner holes of the sleeve-shaped body respectively via an insulator, the inner hole of the sleeve-shaped body is provided with a shielding layer connecting structure which is fixedly connected with a shielding layer of the corresponding lead, and the front end of the sleeve-shaped body is provided with at least one reinforced grounding pin which is fixedly welded to the printed board. The connection assembly and the fixing sleeve thereof can process shielding wires and prevent the pins from bearing a force independently.

Description

technical field [0001] The invention relates to a connecting assembly and a fixing sleeve for connecting wires and printed boards. Background technique [0002] In the era of information systems, miniaturization and integration have become a trend. Almost all system chips and boards are integrated into printed boards, and then placed inside the chassis equipment, and not all external interfaces can be accessed from printed boards. To lead directly out of the equipment, it is often necessary to install a wired socket on the equipment panel, and then guide the wires to the printed board. The connection structure between the wire and the printed board in the prior art is "a wire lead terminal" disclosed in the Chinese patent CN203562549U. When in use, the wire is fixed in the wire barrel, and the conductive soldering foot is welded on the printed board to realize the connection between the wire and the printed board. The existing wire lead terminal for connecting the wire to ...
