Specific embodiment

The utility model is described in further detail below in conjunction with attached drawing.

Embodiment 1: a kind of cable connector, as shown in Figure 1, including shell 1, the outer conductor 2 being arranged in shell 1, setting Set the inner conductor component 3 in the middle part of in shell 1, the insulator 4 being arranged between outer conductor 2 and inner conductor component 3, setting outside The ring flange 5 of 1 one end of shell, is arranged in inner conductor component 3 close to ring flange 5 one gland nut 6 that 1 other end of shell is arranged in Sealing ring 7 between end and shell 1, one end of inner conductor component 3 protrudes from ring flange 5.

As depicted in figs. 1 and 2, it is removably connected with covering inner conductor component 3 on ring flange 5 and protrudes from 5 part of ring flange Protection cap 8, protection cap 8 is made of plastic material, is provided with fixation kit between protection cap 8 and ring flange 5.Ring flange 5 On offer symmetrical first through hole 51 and the second through-hole 52, offered in protection cap 8 corresponding with first through hole 51 Third through-hole 81, fourth hole 82 corresponding with the second through-hole 52.Fixation kit includes being arranged in first through hole 51 and third Pin 101 between through-hole 81, across the second through-hole 52 and fourth hole 82 fixing bolt 102, be threaded in fixed spiral shell Bolt 102 passes through the fixture nut 103 on 82 one end of fourth hole.

As depicted in figs. 1 and 2, while in ring flange 5 multiple circumferentially arrays point are offered on the end face of protection cap 8 The limiting slot 53 of cloth is wholely set multiple limited posts 83 being respectively embedded in different limiting slots 53, protection cap in protection cap 8 8 side is provided with skid resistance strip 84.The inside of protection cap 8, which is adhesively fixed, cushion 86, and cushion 86 uses rubber material It is made, end face of the cushion 86 close to inner conductor component 3 far from gland nut 6.

As depicted in figs. 1 and 2, the first annular groove 11 is offered on the end face of protection cap 8 in shell 1, protection cap 8 is close The end face of shell 1 offers the second annular groove 85 of corresponding first annular groove 11, be provided in the first annular groove 11 and the second annular groove 85 to The tightly elastic washer 9 between 85 inner wall of 11 inner wall of the first annular groove and the second annular groove, elastic washer 9 be made of rubber material and Circular in cross-section.

Implementation principle: protection cap 8 is installed on ring flange 5 by fixation kit and realizes covering inner conductor component 3, thus right Inner conductor component 3 is protected, so that cable connector is during transportation, inner conductor component 3 is not susceptible to collide with, while Elastic washer 9 is set in first annular groove 11 of shell 1, so that when through fixation kit connection, pressure that protection cap 8 will not be excessive Tight ring flange 5, thus the problem of surface for reducing ring flange 5 is worn；

Ring flange 5 usually realizes connection by pin 101 and bolt, at this time when on the shell for be mounted on external equipment In order to take the connection of ring flange 5 and protection cap 8, the connection of ring flange 5 and external equipment into account, fixation kit uses pin 101, consolidates Determining bolt 102 cooperates 103 two ways of fixture nut to be attached, thus on the shell that ring flange 5 is mounted on external equipment When, pin 101 and fixing bolt 102 can be used for installation of the ring flange 5 on the shell of external equipment.

It is embedded in the limiting slot 53 on ring flange 5 in the limited post 83 in protection cap 8, it can be achieved that being carried out to protection cap 8 It positions, so that the third through-hole 81 in the first through hole 51 and protection cap 8 on ring flange 5 is aligned, second on ring flange 5 Fourth hole 82 on through-hole 52 and protection cap 8 is aligned.

Alignment is realized because the limited post 83 in protection cap 8 is embedded in the limiting slot 53 on ring flange 5, at this time because of limited post Frictional force between 83 and limiting slot 53 causes protection cap 8 to be not easy to remove, so that skid resistance strip 84 be arranged in protection cap 8, increases Add frictional force when holding protection cap 8, final realize conveniently removes protection cap 8.

The second annular groove 85 of corresponding first annular groove 11 is offered in protection cap 8, rubber washer protrudes from the first ring at this time The part of slot 11 is embeddable in the second annular groove 85, to reduce during protection cap 8 is fastened on ring flange 5, rubber washer The case where deviating from from the first annular groove 11.

Protection cap 8 adopt it is made of plastic reduce cost, if but when 8 deformation of protection cap at this time be easy to bump to inner conductor Component 3, the cushion 86 in 8 inside of protection cap can be realized buffering at this time, reduce the gouge of inner conductor component 3.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
