Description

A kind of solid connector inner conductor

technical field

The invention relates to the technical field of electrical connectors, in particular to inner conductors of electrical connectors.

Background technique

Existing connectors include an inner conductor and an outer conductor, and the inner conductor is the core of the connector. A reliable connector must have a perfect inner core. The existing inner conductors generally have jacks, and the outer ones have jacks. The conductive connection can be realized as long as the pin is inserted into the socket. Although the existing connector can meet the requirement of the conductive connection, the reliability of the connection is poor.

Contents of the invention

The purpose of the present invention is to provide a stable inner conductor of the connector, which can realize two-way limit and further improve the stability and reliability of the connection.

The object of the present invention is achieved in this way: a stable connector inner conductor, including a main socket with a rotary body structure and a main socket, and a reinforced connection sleeve and a limit sleeve with a circular sleeve structure. The reinforcing connection sleeve includes a middle base part of a circular sleeve structure, and two radially shrinkable expansion sleeve parts respectively located at the two axial ends of the middle base part. The notch where the reinforcement connecting sleeve fits in the axial direction; when assembled, one of the expansion sleeve parts is in the position of the main socket hole and is tightly fitted with the inner wall of the main socket hole, and the other expansion sleeve part is in the limit sleeve Position and tight fit with the inner wall of the limit sleeve;

The main connecting socket, the reinforcing connecting sleeve and the limiting sleeve are arranged coaxially.

Compared with the prior art, the beneficial effect of the present invention is that: it can realize two-way limit, which further improves the stability and reliability of the connection; since two expansion sleeves are provided, one of the expansion sleeves is inserted into the The main socket, the other expansion sleeve is inserted into the limit sleeve, so that the two expansion sleeves are compressed and shrink radially inward to hug the incoming wires, so as to realize two-way limit and completely lock. Hold the position of the incoming wire to prevent loosening.

As a further improvement of the present invention, the expansion sleeve part is provided with a locking fitting surface of a cylindrical surface structure that closely matches the inner wall of the limiting sleeve, and the loading end of the locking fitting surface is provided with an assembly chamfer. It is convenient to set the assembly benchmark, and the matching area between the expansion sleeve and the limit sleeve is increased to enhance the strength of the connection.

As a further improvement of the present invention, the two axial ends of the intermediate base part are respectively facing and abutting against the end of the main socket and the end of the limit sleeve when assembled. It is convenient to set the assembly benchmark.

Detailed ways

As shown in Figure 1-3, a stable connector inner conductor includes a main socket 1 with a rotary body structure and a main socket hole 1a, and a reinforced connection sleeve 2 with a circular sleeve structure and a limit sleeve. 3. The reinforcement connecting sleeve 2 includes a middle base part 201 with a circular sleeve structure, and two radially shrinkable expansion sleeve parts 202 respectively at the two axial ends of the middle base part 201. The expansion sleeve parts 202 are provided with a plurality of circumferentially uniform , the notch 203 whose extension direction is adapted to the axial direction of the reinforced connection sleeve 2; when assembled, one of the expansion sleeve parts 202 is located in the main socket hole 1a and tightly fits with the inner wall of the main socket hole 1a, and the other expands The sleeve part 202 is located inside the limiting sleeve 3 and closely fits with the inner wall of the limiting sleeve 3; the main socket hole 1a, the reinforced connecting sleeve 2, and the limiting sleeve 3 are arranged coaxially.

During assembly, one of the expansion sleeve parts 202 is inserted into the main socket hole 1a, and the other expansion sleeve part 202 is inserted into the limit sleeve 3, so that the two expansion sleeve parts 202 are compressed and shrink radially inward, To hold the incoming wires tightly, so as to realize two-way limit and completely lock the position of the incoming wires.

The expansion sleeve portion 202 is provided with a locking fitting surface 205 of a cylindrical surface structure closely matched with the inner wall of the limiting sleeve 3 , and an assembly chamfer 204 is provided at the loading end of the locking fitting surface 205 . to increase the strength of the connection.

The two axial ends of the above-mentioned intermediate base part 201 are respectively facing and abutting against the end of the main socket 1 and the end of the limit sleeve 3 during assembly. It is convenient to set the assembly benchmark.

The present invention is not limited to the above-mentioned embodiments. On the basis of the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and modifications to some of the technical features according to the disclosed technical content without creative work. Deformation, these replacements and deformations are all within the protection scope of the present invention.
