Description

The how coaxial high density boundling of radio frequency connector

One, technical field:

The utility model relates to a kind of connector, especially relates to the how coaxial high density boundling of a kind of radio frequency connector.

Two, background technology:

In the background technology, more for a long time, not only install wastes time and energy traditional radio frequency (RF) coaxial connector at same panel connecting path, and it is big to take up room, and causes production cost to increase, and panel connector One's name is legion seems in disorder, thereby can not satisfy the existing market requirement.Traditional radio frequency (RF) coaxial connector is widely used in the signal transmission network, plays that transmission line is electrically connected, centrifugation.When connecting path is a lot, if adopt the scheme of traditional connector, the situation of densely covered connector on the panel will appear, give in disorder sensation.Moreover can cause to connect or to disconnect a path required time long, labour intensity is big.

Three, utility model content:

The utility model provides the how coaxial high density boundling of a kind of radio frequency connector in order to solve the weak point in the above-mentioned background technology, and its high density that realizes happy radio frequency (RF) coaxial connector is integrated, has higher Mechanical Reliability and good electric property.

For achieving the above object, the technical solution adopted in the utility model is:

The how coaxial high density boundling of a kind of radio frequency connector, it is characterized in that: comprise public plug and female, it is characterized in that: the outer conductor inwall front end of public plug is provided with three asymmetric protruding keys, the inwall center is evenly distributed with a plurality of coaxial transmission passages on same envelope circle, in equally distributed a plurality of coaxial transmission passages, be provided with the corresponding dielectric and the inner wire of public plug, the contact cylindrical of the outer conductor of female is provided with protruding key and carries out three adaptive asymmetric grooves, be provided with the inner wire of female in the coaxial channel of the outer conductor of female, dielectric and little shell, contact head is surrounded on little shell oral area cylindrical, the connection swivel nut of female is connected with the outer conductor of female by snap ring, is provided with sealing ring between public plug and the female.

Compared with prior art, the advantage and the effect that the utlity model has are as follows:

1, the utlity model has once to connect and just can realize that the action of a plurality of channel signals, overall volume are little, easy for installation, can realize the advantage that outdoor water-proof seals, connection reliability is high.Simultaneously, the end face way of contact of employing can be eliminated the deviation when docking, and can effectively improve the electric property and the reliability of product;

2, a plurality of paths are integrated in the connector in the utility model, have objectively significantly reduced number of connectors under the situation that guarantees connecting path, make panel become succinctly, and the connect hours that brings system is also wanted much less.

Among the figure, 1-public plug, 2-female, the inner wire of 3-public plug, the dielectric of 4-public plug, the outer conductor of 5-public plug, the inner wire of 6-female, the dielectric of 7-female, the contact head of 8-female, the little shell of 9-female, the outer conductor of 10-female, the sealing ring of 11-female, the swivel nut of 12-female.

Five, embodiment:

The utility model comprises public plug 1 and female 2, and both connect cable by rear port.Referring to Fig. 1 and Fig. 2,

Described public plug 1 comprise outer conductor 5 with a plurality of coaxial channels and be arranged in each passage inner wire 3 and around the dielectric 4 of inner wire 3.Inner wire 3 is cylindric, the tapered shape transition face of its front end has a segment distance behind the transition face, and the certain face of cylinder of diameter, be used for matching the requirement when this segment distance should satisfy the public type plug 1 of connector and parent form plug 2 and plugs together with the perforate of parent form plug central inner conductor front end.

Dielectric 4 is a sleeve-like, places between inner wire 3 and the outer conductor 5, is used for fixing inner wire 3; Outer conductor 5 is for having the outer conductor of a plurality of coaxial channels, the inwall front end has three asymmetric protruding keys and is evenly distributed on a plurality of coaxial transmission passages on the same envelope circle at the inwall center, and in reference surface center cylindrical boss is arranged, be press-fitted with the fixing employing of dielectric interference and realize.Referring to Fig. 3 and Fig. 4, female 2 comprises outer conductor 10 with a plurality of coaxial channels and the inner wire 6 in each passage and around the dielectric 7 of inner wire 6 and around the little shell 9 of dielectric 7, elastic contact head 8 is looped around little shell 9 head cylindricals, sealing ring 11 is enclosed within outer conductor 10 cylindrical step places, connects swivel nut 12 around outer conductor 10.Inner wire 6 is cylindric, adopts and opens lobe formula structure.Its front end has shrinkage pool, plugs together use with the inner wire 3 of public plug, and its shrinkage pool degree of depth must be greater than the inner wire 3 front end transition faces of public plug and the summation of the certain face of cylinder of diameter length; Requirement in the time of should satisfying connector public plug 1 and female 2 and plug together; Dielectric 7 is a sleeve-like, and centering inner wire 6 front ends play fixedly inner wire 6; The outer conductor 10 of female is a sleeve-like, and front end has splits groove.Inside has the barb that the requirement of certain inclined-plane is arranged, and this barb can be used with the annular recess of little shell 9 in order to fixedly contact head 8 and little shell 9, and realizes certain axial float function; The little shell 9 of female is a sleeve-like, and interface front end cylindrical has slick and sly transition, has an annular groove after arc transition, and its width should be greater than the width of contact head 8 inner barbs; The outer conductor 10 of female is for having the outer conductor of a plurality of coaxial channels, has three asymmetric grooves on the contact cylindrical and is evenly distributed on a plurality of coaxial transmission passages on the same envelope circle at the center, and in reference surface center cylindrical recess is arranged.Working to fix each coaxial channel connects; Sealing ring 11 is a sleeve-like, is surrounded on the face of cylinder root that outer conductor 10 front ends have projection, plays the dust and moisture effect; Swivel nut 12 is a sleeve-like, is surrounded on outer conductor 10 inside, has connecting thread and helps two connectors to connect;
