Abstract

The utility model discloses a pin connector, which comprises a pin (1), insulators (2, 3), shells (4, 5) and a pressing sleeve (6); wherein, the insulators (2, 3) are respectively tightly installed on both ends of the pin (1); the insulator (2) is tightly installed in the shell (5); the pressing sleeve (6) is tightly sleeved on the shell (4); the middle part of the pin (1) is provided with an annular step (11), both sides of which respectively are against the sunken bottom (21) of the insulator (2) and the end surface (31) of the insulator (3); and the shell (4) is tightly installed between the inner hole of the shell (5) and the outer circumference of the insulator (3). The structure axially positions the pin (1), thus fundamentally preventing the pin (1) from falling off a terminal, and ensuring that the pin connector can be more firmly and stably installed on a communication device.

Description

A kind of contact pin connector

Technical field

The utility model relates to a kind of communication accessory, and especially a kind of contact pin connector that is used in the communication apparatus belongs to the communication equipment technical field.

Background technology

At present, in communications industry,, need use contact pin connector in order to guarantee the stable connection of communication device.And the common employing of the contact pin of existing contact pin connector directly is pressed into, this structure only depends on the frictional force between the inwall of the appearance of contact pin and insulator to come clamping cables, clamping force is limited, during work under the effect of the extraneous power or the temperature difference, contact pin takes place loosening easily or comes off from joint, influence its normal service behaviour, in addition, existing contact pin connector assembling is also inconvenient.

Summary of the invention

The purpose of this utility model is at the contact pin of existing contact pin connector and joint easily come off loosening and problem easy for installation, proposes a kind of communication device contact pin connector of split-type structural.

The technical solution of the utility model is:

A kind of contact pin connector, comprise contact pin 1,

insulator

2,3,

shell

4,5, gland 6, described

insulator

2,3 is fitted in the two ends of contact pin 1 respectively, described insulator 2 is fitted in the shell 5, described gland 6 glands are on shell 4, the middle part of described contact pin 1 is provided with ring-shaped step 11, and the two sides of described ring-shaped step 11 are resisted against respectively on the end face 31 of the counterbore bottom surface 21 of insulator 2 and insulator 3; Described shell 4 is fitted between the outer peripheral face of the endoporus of shell 5 and insulator 3.

Described shell 4 is the cylindrical body that first end has radially overhanging step 41, and its endoporus is the step through hole, and the end face 32 of described insulator 3 is on endoporus step 42, and described radially overhanging step 41 is resisted against on the end face of shell 5.

The inner end of described insulator 2 has radially overhanging step 22, and the axial both ends of the surface of described step 22 are resisted against respectively on the counterbore step of second end of shell 4 and shell 5.

The utlity model has following advantage:

Because contact pin of the present utility model 1 middle part is provided with ring-shaped step 11, the two sides of this ring-shaped step 11 are resisted against respectively on the end face 31 of the counterbore bottom surface 21 of insulator 2 and insulator 3, such structure makes contact pin 1 be subjected to insulator 2 and insulator 3 axial limitings and can not go here and there, equally, the axial limiting that two axial end faces of insulator 3 are subjected to insulator 2 and shell 4 respectively can not be gone here and there, and the inner end of insulator 2 has radially overhanging step 21 and is subjected to second end of shell 4 and the counterbore step axial limiting of shell 5 respectively.The utility model has fundamentally limited contact pin 1 and has come off with joint, has guaranteed the performance of product, also can make that the utility model is installed more firmly on communication device, stability is better simultaneously.

Description of drawings

Fig. 1 is a structural representation of the present utility model

Embodiment

Following structure drawings and Examples are further described the utility model.

As shown in Figure 1, a kind of contact pin connector, comprise contact pin 1,

insulator

2,3,

shell

4,5, gland 6,

insulator

2,3 is fitted in the two ends of contact pin 1 respectively, insulator 2 is fitted in the shell 5, gland 6 is enclosed within on the shell 4, and the middle part of contact pin 1 is provided with ring-shaped step 11, and the two sides of ring-shaped step 11 are resisted against respectively on the end face 31 of the counterbore bottom surface 21 of insulator 2 and insulator 3; Shell 4 is fitted between the outer peripheral face of the endoporus of shell 5 and insulator 3.

Shell 4 is the cylindrical body that axial first end has radially overhanging step 41, and its endoporus is the step through hole, and the end face 32 of insulator 3 is on endoporus step 42, and radially overhanging step 41 is resisted against on the end face of shell 5.The inner end of insulator 2 has radially overhanging step 21, and the axial both ends of the surface of step 21 are resisted against respectively on the counterbore step of axial second end of shell 4 and shell 5.

Assembling process of the present utility model is as follows:

Insulator

2,3 is a positioning reference with the ring-shaped step 11 at contact pin 1 middle part, is fitted in the two ends of contact pin 1 respectively; Again insulator 2 is pressed into shell 5, then shell 4 is fitted between the outer peripheral face of the endoporus of shell 5 and insulator 3, at last gland 6 is fitted on the axial outer end of shell 4.

In addition to the implementation, the present invention can also have other execution modes, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection range of requirement of the present invention.
