Description

A kind of radio frequency (RF) coaxial connector

Technical field

The utility model relates to technical field of measurement and test, is specifically related to radio frequency (RF) coaxial connector.

Background technology

Radio frequency (RF) coaxial connector, produces widely, is applied to microwave communication, post and telecommunications engineering, and aerospace measurement system, in various precision measurements field.

Current powerful radio frequency (RF) coaxial connector, is connected between its swivel nut and housing, mainly relies on two kinds of modes to connect.It is a kind of is Snap ring structure, and this structure needs special assembly tooling, and many when expense and assembler, efficiency of assembling is not high; Another kind of, be that two housings excessively coordinate mutually, then clamp connection swivel nut, this kind of structure, during assembling, need use Pneumatic press, not so the bad control of pressing effect, in actual use procedure, often finds, due to the undesirable situation of pressing effect between two housings, thereby can make two housings separated, swivel nut comes off, and causes scrapping of whole product.

Existing radio frequency (RF) coaxial connector exists efficiency of assembling low, and structural stability is poor, and product reliability can be poor.

Utility model content

The utility model provides a kind of radio frequency (RF) coaxial connector, and the utility model has solved existing radio frequency (RF) coaxial connector and existed efficiency of assembling low, and structural stability is poor, the problem that product reliability can differ from.

For addressing the above problem, the utility model adopts following technical scheme: a kind of radio frequency (RF) coaxial connector, and an inner wire 7 is pressed in the hole of insulator from left to right, and both are for closely cooperating; Above-mentioned inner wire 7 is pressed in housing 5 with the integral body of insulator 6, and there is hangnail structure housing 5 inner hole walls and insulator cooperation place;

Housing 5 outer surfaces form the ledge structure that four joint diameters increase gradually from left to right, at second section ledge surface, have the along the circumferential direction groove 8 of annular;

The snap ring 3 of elastomeric material is arranged in the groove 8 of housing 5, and swivel nut 1 is placed on housing second section step from housing 5 left ends, and snap ring 3 is positioned at swivel nut 1;

Rubber ring 2 is positioned at swivel nut 1 and is placed on the root of the left end first segment step of housing 5.

Further, a kind of radio frequency (RF) coaxial connector of the present utility model also has following features: the height of the outer surface of snap ring 3 outstanding housings 5 is between 0.5-0.8mm, the stand out 0.1-0.2mm of the width of snap ring and enclosure slot.

The utility model radio frequency (RF) coaxial connector, discloses a kind of structure with snap ring, does not need special frock assembling, has saved processing cost, has also improved efficiency of assembling.Empirical tests, this Stability Analysis of Structures is reliable, more easily realizes the control of product reliability energy.

Symbol description in figure: swivel nut 1, rubber ring 2, snap ring 3, hangnail structure 4, housing 5, insulator 6, inner wire 7, groove 8.

Embodiment

With best embodiment, the utility model is described in detail below.

As shown in Figure 1, a kind of radio frequency (RF) coaxial connector, an inner wire 7 is pressed in the hole of insulator from left to right, and both are for closely cooperating; Above-mentioned inner wire 7 is pressed in housing 5 with the integral body of insulator 6, and there is hangnail structure housing 5 inner hole walls and insulator cooperation place, can prevent that insulator is toward rollback, and hangnail upper punch has the breach of 4-6 groove, can prevent from rotating between insulation and housing;

As shown in Figure 2, first swivel nut 1 is overlapped to upper shell second section steps from housing 5 left ends, and shift the root of second section step onto; And by the snap ring of an elastomeric material 3 left end cover upper shell the first external diameter step from housing 5, and by hand or tweezers snap ring 3 is shifted onto in the groove 8 of housing 5.

Finally again rubber ring 2 is overlapped to first external diameter step of left end of upper shells 5, and be pushed into the root of first step, so just formed the finished product of connector.

The height of the outer surface of the utility model snap ring 3 outstanding housings 5 is between 0.5-0.8mm, the stand out 0.1-0.2mm of the width of snap ring and enclosure slot.

The utility model adopts a snap ring, guarantees the tight double team between itself and housing, and meanwhile, the external diameter of snap ring exceeds the large external diameter 0.5-0.8mm of housing, snap ring width 1.0mm, radial thickness 1.3-1.5mm.This height can be stable block connection swivel nut, when screw thread screws, glue does not fall, thereby makes the electric property of whole connector may obtain stable control, and the assembling of snap ring is easy, does not need special tooling, saves man-hour.

The utility model with the advantage that the first prior art is compared is: reduced part production cost, Vehicle Processing is easy, has reduced assembly difficulty, thereby has improved efficiency of assembling. improved the competitiveness of product in market.

The utility model is compared with the second prior art, has increased the stability that connects swivel nut, can not cause scrapping of product because of the interference fit shakiness of two housings, has improved the first-time qualification rate of product, makes the unfailing performance of product better.

Finally it should be noted that: obviously, above-described embodiment is only for the utility model example is clearly described, and the not restriction to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without also giving all execution modes.And the apparent variation of being amplified out thus or change are still among protection range of the present utility model.
