The connector comprises contact fingers (1), contact pins (2), insulators (3), an outer shell (4) or the like, wherein the contact fingers (1) are fixed in the outer shell (4), contact pins (2) are arranged in the insulators (3), one end of it is located in the contact fingers (1), contact pins (2) are insulate with the contact fingers (1), the connecting sleeve (8) is arranged on the outer shell (4), one end of the outer shell (4) projects out of the connecting sleeve (8), a spring (6) is packed on the outer shell (4), a compression ring (5) is arranged on the outer shell (4) and it's connected with one end of the spring (6), another end of the outer shell (4) without spring (6) is located on the connecting sleeve (8), and a steel ball (9) is arranged on the side walls, an arc groove is fabricated on either side adjacent to the steel ball on the inner wall of the connecting sleeve. The utility mode has the advantages that the mechanical strength is high and the self-locking and unlocking is stable and reliable.

Description

RF coaxial pole connector

Technical field

The utility model relates to a kind of telecommunication apparatus and radio instrument radio frequency (RF) coaxial connector, especially a kind of contact pin type connector, specifically a kind of RF coaxial pole connector.

Background technology

At present, the self-locking of RF coaxial pole connector commonly used and release mechanism all are to adopt reed mechanism to achieve the goal, but because reed is thinner, generally in 0.3 millimeter, it is yielding, and precision be cannot say for sure to demonstrate,prove, cause locking mechanical strength deficiency, often cause self-locking and release to lose efficacy, directly influence the normal performance of its function, very easily when being subjected to the excess load vibration or stretching, cause signal interruption.

Summary of the invention

The purpose of this utility model is self-locking and the release mechanism mechanical strength deficiency that exists at existing contact pin connector, easily causes to pull and cause the problem of signal interruption, and the intensity that designs a mechanism is big, the reliable RF coaxial pole connector of self-locking release.

The technical solution of the utility model is:

A kind of RF coaxial pole connector, comprise contact head 1, contact pin 2, insulator 3, shell 4, pressure ring 5, spring 6, adapter sleeve 8, contact head 1 is fixedly mounted in the shell 4, contact pin 2 is installed in the insulator 3, the one end is arranged in contact head 1, contact pin 2 passes through insulator 3 and mutually insulated with contact head 1, insulator 3 also is fixedly mounted in the shell 4, adapter sleeve 8 is installed on the shell 4, one end of shell 4 stretches out outside the adapter sleeve 8, spring 6 is sleeved on the shell 4 and between shell 4 and adapter sleeve 8, pressure ring 5 is fitted on the shell 4 and offsets with an end of spring 6, it is characterized in that not being equipped with on the perisporium of an end in adapter sleeve 8 of mounting spring 6 and make the steel ball 9 that keeps setting the gap between adapter sleeve 8 and the shell 4, on the inwall of adapter sleeve 8, respectively be processed with an arc groove 10 near both sides, steel ball position at shell 4,11.

The quantity of described steel ball 9 is three, and they are evenly arranged on the shell wall of shell 4.

In the outside of pressure ring 5 gland 7 is installed.

The utlity model has following advantage:

1, self-locking property of the present utility model is more natural, stable, long service life.

2, volume is little, precision is high, connection reliability is strong, and can prevent because of the vibration of unexpected excess load or pull the advantage that causes signal interruption.

3, the utility model has been cancelled reed self-locking mechanism commonly used, adopts steel ball to realize self-locking and release, and its mechanical structure is reliable, and enough mechanical strengths are arranged, and self-locking and release are quick, light.

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 RF coaxial pole connector, it is mainly by contact head 1, contact pin 2, insulator 3, shell 4, pressure ring 5, spring 6, adapter sleeve 8 is formed, wherein contact head 1 is fixedly mounted in the shell 4 by pressing, contact pin 2 is installed in the insulator 3, the one end is arranged in contact head 1, contact pin 2 passes through insulator 3 and mutually insulated with contact head 1, insulator 3 also is fixedly mounted in the shell 4, adapter sleeve 8 is installed on the shell 4, one end of shell 4 stretches out outside the adapter sleeve 8, spring 6 is sleeved on the shell 4 and between shell 4 and adapter sleeve 8, pressure ring 5 is fitted on the shell 4 and offsets with an end of spring 6, be not equipped with on the perisporium of an end in adapter sleeve 8 of mounting spring 6 at shell 4 and make three steel balls 9 that keep setting the gap between adapter sleeve 8 and the shell 4, three steel balls 9 are evenly arranged on the shell wall of shell 4, the quantity of steel ball 9 also can be more than two or three during concrete enforcement, respectively is processed with an arc groove 10 that steel ball 9 is slipped near both sides, steel ball position on the inwall of adapter sleeve 8,11.In the outside of pressure ring 5 gland 7 is installed.

In addition, when specifically implementing, the quantity of spring 6 can adopt one, also can adopt two, when adopting two springs 6, the boss ring that spring is cut apart in an installation can be set at the inwall of adapter sleeve 8.As shown in Figure 1.

When pressing gland 7 left with hand, then can make shell 4 overcome the active force of spring 6, and steel ball 9 is pushed in the arc groove 10 on the left side on adapter sleeve 8 inwalls, otherwise when the end that stretches out with hand propelled shell 4 outside the adapter sleeve 8, steel ball 9 can be pushed in the arc groove 11 on the right on adapter sleeve 8 inwalls, just shell 4 can be made a certain amount of move left and right and makes and certain stroke is arranged between the connected piece and can not pull in adapter sleeve 8, and realizes corresponding self-locking and unlocking function.

Assembling process of the present utility model is:

Tight fit presses contact head 1 and shell 4 earlier, to make the spacing that keeps 0.1～1mm between adapter sleeve 8 and the shell 4 do supported at three point with three steel balls 3 between adapter sleeve 8 and the shell 4, so that relatively move, again pressure ring 5 and shell 4 are made tight fit, load onto after contact head 1 and shell 4 tight fits that spring 6 refills upper joint sleeve 8 and compress and get final product with pressure ring 5.
