Abstract

The utility model discloses a waterproof coaxial connector, which comprises a threaded sleeve, an outer shell body, an insulating supporting body, an inner conductor, an end caging body, and a pressure tube, and also comprises a waterproof gum cover. At least a concave annular groove is formed on the front part of the outer shell body along the circumferential direction; an annular lug boss corresponding to the concave annular groove of the outer shell body is formed on an inner hole of the waterproof gum cover along the circumferential direction; the waterproof gum cover is contained outside the coaxial connector along the circumferential direction; the inner hole of the waterproof gum cover forms the interference fit with the periphery of the coaxial connector and forms the interference fit with the periphery of a cable, thereby being hard to be fallen off from the coaxial connector. When the waterproof coaxial connector is used outdoors, rainwater cannot sink into the coaxial connector and the cable, thereby ensuring the normal working of the connected equipment.

Description

The waterproof coaxial connector

Technical field

The utility model relates to a kind of coaxial connector, particularly a kind of coaxial connector of energy waterproof.

Background technology

Coaxial connector is generally used for connecting coaxial cable as the input/output terminal of communication apparatus.Use the occasion of communication apparatus at some, for example, the coaxial connector that uses between the base station indoor equipment of 3G (Third Generation) Moblie TD-SCDMA system and far-end subsystem, often need to use out of doors, existing common coaxial connector runs into the wind and rain invasion and attack when outdoor application, the short circuit of will leaking, influence the equipment operate as normal, need not be how long, this coaxial connector will lose efficacy in corrosion.

Summary of the invention

In order to overcome the shortcoming of prior art, the utility model provides a kind of coaxial connector of energy waterproof, and this coaxial connector can be in outdoor long-term use, the problem that the short circuit of can not leaking, corrosion were lost efficacy.

The utility model is achieved by the following technical programs.

A kind of waterproof coaxial connector comprises swivel nut, shell body, insulation support body, inner wire, pressure urosome, pressure pipe; The rear portion of described shell body is connected with swivel nut by snap ring; Described pressure urosome is a tubular body, there is through hole at its center, press the bigger head of urosome diameter to be housed in the front portion of shell body, press the less afterbody of urosome diameter to be housed in the pressure pipe, the centre bore of pressure urosome is accommodated the head of cable, and cable shield is clipped in the pressure pipe endoporus and presses between the urosome periphery, and inner wire is housed in the centre bore of insulation support body, the cable inner core inserts in the inner wire hole, and described shell body is fixedlyed connected vertically with pressure pipe and is integral; Also comprise water-proof rubber sleeve.Described water-proof rubber sleeve is along circumferentially being included in outside the coaxial connector.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid waterproof coaxial connector, the front portion of wherein said shell body circumferentially are shaped on the recessed cannelure at least one place.

Aforesaid waterproof coaxial connector, the endoporus of wherein said water-proof rubber sleeve circumferentially are shaped on the cannelure corresponding annular boss recessed with described shell body, and the periphery interference fit of this water-proof rubber sleeve endoporus and coaxial connector is with the cable periphery interference fit that is connected.

The beneficial effects of the utility model are, when using the waterproof coaxial connector out of doors, because water-proof rubber sleeve is along circumferentially closely wrapping in outside coaxial connector and the cable that is connected, rainwater can not infiltrate in coaxial connector and the cable, thereby has guaranteed the equipment operate as normal that connected.Owing to cooperating of at least one place annular boss and hollow toroid groove arranged between water-proof rubber sleeve and the shell body, makes that water-proof rubber sleeve is not easy to come off from coaxial connector.

Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.

Embodiment

As shown in Figure 1, waterproof coaxial connector of the present utility model comprises swivel nut 1, shell body 2, insulation support body 3, inner wire 4, presses urosome 5, pressure pipe 6; The rear portion of described shell body 2 is connected with swivel nut 1 by screw thread; Described pressure urosome 5 is a tubular body, there is through hole at its center, press the bigger head 51 of urosome 5 diameters to be housed in the front portion of shell body 2, press the less afterbody 52 of urosome 5 diameters to be housed in the pressure pipe 6, the centre bore of pressure urosome 5 is accommodated the head of cable, after cutting open, cable shield is clipped between pressure pipe endoporus and the pressure urosome periphery, inner wire 4 is housed in the centre bore 31 of insulation support body 3, inner wire 4 is included in outside the cable inner core, directly pegging graft in cable inner core and inner wire hole, in the present embodiment, uses specific purpose tool that described pressure pipe 6 is pressed into hexagon, make the cable shield hard-pressed bale firmly press tail 5, the cable 8 in the pressure pipe of packing into 6 also firmly is pressed in the ground pressure pipe 6.The front portion of shell body 2 circumferentially is shaped on the recessed cannelure at least one place 21.

As shown in Figure 2, the endoporus of water-proof rubber sleeve 7 circumferentially is shaped on the cannelure 21 corresponding annular boss 71 recessed with described shell body 2.

As shown in Figure 3, water-proof rubber sleeve 7 is along circumferentially being included in outside the coaxial connector, and the endoporus of described water-proof rubber sleeve 7 and coaxial connector periphery interference fit are with the cable periphery interference fit that is connected.Rainwater can not infiltrate in coaxial connector and the cable, thereby guaranteed the equipment operate as normal that connected, owing to cooperating of at least one place annular boss 71 and hollow toroid groove 21 arranged between water-proof rubber sleeve 7 and the shell body 2, makes water-proof rubber sleeve 7 be not easy to come off from coaxial connector.

In addition to the implementation, the utility model 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 the utility model requirement.
