Three anti-connectors
Technical field
The utility model relates to a kind of three anti-connectors.
Background technology
So-called three anti-connectors refer to a kind of energy waterproof, anticorrosion and radiation-resistant connector.Three anti-tail portion of connector shells of prior art and the sealing of cable generally adopt silicon rubber crush seal or normal temperature casting glue to seal, due to silicon rubber aging after to follow the string and sealing is easily ftractureed and come off in the environment of long-time high temperature, particularly when serviceability temperature is more than 200 DEG C, the useful life of three anti-connectors of prior art is only generally 10 years, therefore three of the prior art problems that anti-connector ubiquity sealing effectiveness is poor, useful life is short.
Utility model content
The technical problems to be solved in the utility model is three defects that anti-connector sealing effectiveness is poor, physical life is short in order to overcome prior art, provides a kind of three anti-connectors.
The utility model solves above-mentioned technical problem by following technical proposals:
A kind of three anti-connectors, comprise contact, mesh plate and shell, this mesh plate is arranged at a side of this contact, this shell for holding this contact and this mesh plate, and this inner surface of outer cover be connected with this contact and this mesh plate after outer surface agree with mutually;
This contact comprises integrated front insulating part and rear insulating part, this contact also comprises and axially runs through the many contacts inserting in this front insulating part, this rear insulating part is in axial direction provided with multiple through hole, the plurality of through hole respectively with these many contact one_to_one corresponding, there is a container cavity side of this rear insulating part, and this container cavity is for connecting this mesh plate;
This mesh plate is made up of polyetheretherketonematerials materials, and this mesh plate is in axial direction provided with through multiple cable jacks.
Preferably, this shell comprises plug front casing, plug connecting ring and plug rear casing, and this plug connecting ring is for connecting this plug front casing and this plug rear casing.
Preferably, the circumferential surface of this rear insulating part in axial direction has a groove, and this inner surface of outer cover has a projection, this groove and this protrusions.
Positive progressive effect of the present utility model is: the utility model adopts polyether-ether-ketone as the encapsulant of three anti-connectors, the heat resistance utilizing it high and toughness, improve the sealing effectiveness of three anti-connectors, waterproof, anticorrosion, radiation protection ability obviously strengthen.The utility model structure is simple, convenient for production and cost is low.

Embodiment
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
A kind of three anti-connectors, as Figure 1-3, comprising contact 1, being arranged at the mesh plate 2 of contact 1 one sides, for holding the shell 3 of contact 1 and mesh plate 2.Contact 1, as shown in Figure 3, comprise integrated front insulating part 11 and rear insulating part 12, contact 1 also comprises and axially runs through the many contacts 13 inserting in front insulating part 11, rear insulating part 12 is in axial direction provided with multiple through hole 121, multiple through hole 121 respectively with many contacts 13 one_to_one corresponding, there is a container cavity 122 side of rear insulating part 12, and this container cavity 122 is for connection network orifice plate 2.Mesh plate 2 is made up of polyetheretherketonematerials materials, and mesh plate 2 is in axial direction provided with through multiple cable jacks, for interspersed cable conductors 4, as shown in Figure 3.Shell 3 comprises plug front casing 31, plug connecting ring 32 and plug rear casing 33, and plug connecting ring 32 is for attachment plug front casing 31 and plug rear casing 33, and plug rear casing 33 is for the protection of cable conductors 4 and fixed cable.
During assembling, plug rear casing 33 is inserted in cable by the circular hole first along plug rear casing 33 afterbody, by cable conductors 4 one by one through mesh plate 2, the through hole 121 of insulating part 12 after cable conductors 4 through mesh plate 2 is inserted one by one, cable conductors 4 is connected with contact 13 and makes mesh plate 2 part be positioned, in the container cavity 122 of rear insulating part 12, to be connected with contact 1 to make mesh plate 2.Then plug connecting ring 32 is inserted in plug front casing 31, and contact 1 and mesh plate 2 are inserted plug front casing 31, mesh plate 2 one sides are flushed with the edge of plug front casing 31 near plug rear casing 33 side, at this moment plug front casing 31 inner surface be connected with contact 1 and mesh plate 2 after outer surface agree with mutually.Use the afterbody of press-connection machine crimp plug front casing 31, namely near the part of plug rear casing 33 side, seal with mesh plate 2, crimping between mesh plate 2 with cable conductors 4 to realize shell 3.Finally; plug rear casing 33 is contacted with plug front casing 31; outer surface and plug connecting ring 32 inner surface of plug rear casing 33 and plug front casing 31 have the screw thread matched; by rotary connector connecting ring 32; plug front casing 31 is fixedly connected with plug rear casing 33; plug rear casing 33 protects cable conductors 4 effectively, and plays the effect of good fixed cable.
In the present embodiment, the circumferential surface of rear insulating part 12 in axial direction has a groove 123, and this groove 123 and the protrusions of shell 3 inner surface, skid in shell 3 for preventing contact 1.
Although the foregoing describe embodiment of the present utility model, it will be understood by those of skill in the art that this only illustrates, protection range of the present utility model is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present utility model and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection range of the present utility model.
