Technical field

This utility model relates to joint technique field, is specifically related to the jointing of a kind of improvement.

Background technology

Jointing is generally used for the fixing connection between various pipeline, and cable connector is a kind of jointing often used in power system, generally include one for connecting the connection seat of cable, and offer an axially extending bore connecting in seat, enable cable to be inserted in connection seat, or be directly sleeved on the outside connecting seat, thus reaching to connect the effect of cable, and cable connector need to possess certain water resistance, it is prevented that electric leakage. But existing cable connector can only be used for connecting single cable pipeline, and needs access other need to access flexible pipe, braiding webmaster time, owing to the restriction of structure installs also inconvenient, attachment structure is also firm not.

Utility model content

For the deficiencies in the prior art, the purpose of this utility model is in that to provide the jointing of a kind of improvement, it is possible to locking cable, and is easy to the access of other pipelines, and attachment structure is firm.

For achieving the above object, this utility model adopts the following technical scheme that

A kind of jointing of improvement, including connecting seat, one end of this connection seat is provided with thread segment, and the other end connecting seat is set with a metal sleeve, and the outer cover of metal sleeve is equipped with a fixing head, and fixing head is bolted on metal sleeve near the end of thread segment; This fixing head is installed with a shackle member away from the tip inside of thread segment, and shackle member includes ring body and multiple claw, and it is circumferentially distributed that multiple claws are fixedly arranged on ring body and along ring body; The outside of claw is provided with fixture block, and fixing head offers bayonet socket, and fixture block is connected in bayonet socket; A snap ring it is clamped with between metal sleeve and fixing head.

Preferably, connecting seat periphery projection one protuberance, protuberance outer peripheral edge is provided with flat position.

Preferably, fixing head is clamped with a packing ring near between the end and protuberance of thread segment.

Preferably, the inwall of fixing head is connected with sealing ring.

Preferably, shackle member is made up of plastic material.

The beneficial effects of the utility model are in that:

Compared to prior art, the jointing of improvement of the present utility model, it has a thread segment, it is possible to be directly bolted in the pipeline being threaded device, connects efficient and convenient; Connecting the metal sleeve of suit outside seat, it is possible to shielding electromagnetism, it is to avoid by Electromagnetic Interference after connection simultaneously; It addition, and metalwork be also associated with a fixing head, it is simple to the access of other pipelines, attachment structure is firm.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

Fig. 2 is cross-sectional view of the present utility model.

Wherein, 10, seat is connected; 11, protuberance; 12, flat position; 20, metal sleeve; 30, fixing head; 31, bayonet socket; 40, shackle member; 41, ring body; 42, claw; 43, fixture block; 50, packing ring; 60, sealing ring; 70, snap ring.

Detailed description of the invention

Below, in conjunction with accompanying drawing and detailed description of the invention, this utility model is described further:

The jointing of a kind of improvement as shown in Figure 1 and Figure 2, including connecting seat 10, thread segment is set in one end of this connection seat 10, the screw thread of concrete thread segment can be female thread, it can also be external screw thread, so this jointing can directly be bolted on the cable pipeline with installing plate or adapter, connects efficient and convenient, and attachment structure is firm.

And the other end connecting seat 10 is set with a metal sleeve 20, simultaneously in outside suit one fixing head 30 of metal sleeve 20, this fixing head 30 is made to be bolted on metal sleeve 20 near the end of thread segment, convenient installation. In this fixing head 30 fixed shackle member 40 of tip inside away from thread segment, and shackle member 40 includes ring body 41 and the multiple claws 42 being installed on ring body 41, card so can in this fixing head 30 other pipelines of cross-under (such as flexible pipe, the braiding flexible pipe such as webmaster), above-mentioned claw 42 can promptly in the outside of pipeline, playing the effect of locking, annexation is more firm. Certainly, circumferentially distributed along ring body 41 of above-mentioned multiple claws 42, attachment structure is more stable.

In addition, bayonet socket 31 can be offered in fixing head 30, be provided with fixture block 43 in the outside of claw 42 accordingly, make this fixture block 43 be connected in bayonet socket 31, so can realize shackle member 40 and be connected with the fixing of fixing head 30, easy accessibility. It addition, can be clamped with a snap ring 70 between metal sleeve 20 and fixing head 30, this snap ring 70 is for when other pipelines of cross-under, being fastened on outside pipeline, and forms primary Ioops between metal sleeve, it is ensured that the short-circuit safety of circuit, reduces the transfer impedance of electromagnetism; Improve the resistance to tension of shielding pipeline simultaneously.

On said structure basis, above-mentioned metal sleeve 20 is folded between connection seat 10 and fixing head 30, so can shield electromagnetism, it is to avoid cable pipeline is subject to Electromagnetic Interference after connecting.

Preferably, in the present embodiment, the periphery of above-mentioned connection seat 10 can projection one protuberance 11, simultaneously between the fixing head 30 end and protuberance 11 near thread segment, clamp a packing ring 50, so, fixing head 30 with when being connected the connection of seat 10 cable, can add and be solidly connected, simultaneously can also waterproof. It addition, be additionally provided with flat position 12 in protuberance 11 outer peripheral edge, other tool holder are facilitated to connect seat 10.

Preferably, the inwall of above-mentioned fixing head 30 is connected with sealing ring 60, improves the water resistance of this jointing. It addition, above-mentioned shackle member 40 also can be made up of plastic material, because plastic cement can produce certain deformation being squeezed, therefore whole joint can being made more tight with the laminating of pipeline after accessing pipeline, sealed waterproof effect is better.

It will be apparent to those skilled in the art that can technical scheme as described above and design, make other various corresponding changes and deformation, and all these change and deformation all should belong within this utility model scope of the claims.
