Abstract

The utility model relates to a radio frequency coaxial connector, including swivel nut, casing, insulator and inner conductor, casing part nested in in the swivel nut, both connect through the snap ring, the inner conductor is the cable inner core, the insulator is the cable insulation body. The utility model discloses saved radio frequency coaxial connector insulator and inner conductor, with the insulator of cable and inner core insulator and the inner conductor as the connector, the cable insulation body can not project under the high temperature circumstances, and the location is stable, and the electric property is reliable, reduce cost simultaneously, and the assembly is simple, is fit for batch production.

Description

A kind of radio frequency (RF) coaxial connector

Technical field

The utility model relates to a kind of radio frequency (RF) coaxial connector.

Background technology

Radio frequency (RF) coaxial connector generally comprises three parts: housing, insulator and inner wire.The connection of connector and cable, generally first welds inner wire with cable inner core (or crimping), then puts in housing, is positioned by the insulator of enclosure interior, finally housing and cable outer conductor is carried out welding (or crimping).There are some places had much room for improvement in this attaching mode (as shown in Figure 1): 1, and the insulator of enclosure interior can protrude in the case of a high temperature, affects electrical property; 2, when installing cables, distortion known from experience by cable insulation; 3, cost is high, and wire stripping difficulty controls, and the easy rosin joint of inner wire, affects electrical property.

Utility model content

Goal of the invention of the present utility model is: for overcome the above problems provide one in the case of a high temperature cable insulation can not protrude, positioning stablity, the reliable radio frequency (RF) coaxial connector of electric property.

The technical scheme that the utility model adopts is such:

A kind of radio frequency (RF) coaxial connector, comprise swivel nut, housing, insulator and inner wire, described housing parts is nested in described swivel nut, and both are connected by snap ring, and described inner wire is cable inner core, and described insulator is cable insulation.

Further, described housing Inner Front End is provided with cable positioning step, axial location when installing for cable and spacing.

In sum, be technical scheme owing to adopting above-mentioned, the beneficial effects of the utility model are:

The utility model adopts a kind of brand new, directly cable is positioned by the small stair of enclosure interior, the inner core of cable is as the inner wire of connector, the insulator of cable is as the insulator of connector, this new construction possesses following advantage: 1, cable insulation can not protrude in the case of a high temperature, positioning stablity, and electric property is reliable; 2, eliminate the inner wire of connector, insulator, replace inner wire and the insulator of connector with cable inner conductor and insulator, improve the quality of products, reduce costs; 3, assembling is simple, is applicable to batch production.

Accompanying drawing explanation

Fig. 1 is prior art structural representation;

Fig. 2 is structural representation of the present utility model.

Mark in figure: 1, swivel nut; 2, housing; 3, inner wire; 4, insulator; 5, snap ring; 6, cable positioning step.

Embodiment

Below in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 2, a kind of radio frequency (RF) coaxial connector, comprises swivel nut 1, housing 2, insulator 4 and inner wire 3, described housing 2 part is nested in described swivel nut 1, both are connected by snap ring 5, and described inner wire 3 is cable inner core, and described insulator 4 is cable insulation.During installation, the cable stripping line is stretched into connector shell 2, top puts in place.

Described housing 2 Inner Front End is provided with cable positioning step 6, axial location when installing for cable and spacing, prevents displacement from causing product result of use not good.

The utility model eliminates insulator 4 and inner wire 3, and with the insulator of cable and inner core as the insulator 4 of connector and inner wire 3, cable insulation can not protrude in the case of a high temperature, positioning stablity, electric property is reliable, reduces costs simultaneously, assembling is simple, is applicable to batch production.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
