Abstract

The utility model discloses a signal wire junction, which is characterized in that the utility model consists of a core body, a through hole got through a signal wire core wire is arranged inside the core body, a plurality of tapered saliencies are arranged at the tail end of the core body, a rubber seat and a fixed sleeve which can movably moved along the core body are suited at the front end of the core body; the front end of the fixed sleeve is fixed at the tail end of the rubber seat, annular convex tables are arranged on the inner side of the tail end of the fixed sleeve, the tapered saliencies at the tail end of the core body are mutually matched with the annular convex tables to be fixed a signal wire; wherein a connecting nut mutually connected with the outside is also fixed at the front end of the rubber seat. The utility model has the advantages that firstly, the installation is simple, any pair of tool pliers is not required when the junction is arranged, thus the installation time is saved; secondly, the structure is fastened, when the signal wire is arranged, the signal wire is not torn out of the junction because of too much force; thirdly, the structure is simple, therefore being convenient for manufacturing and processing.

Description

A kind of signal wire joint

[technical field]

The utility model relates to a kind of signal wire joint.

[background technology]

Along with the continuous development of electronic product, the holding wire that is used for the signal transmission is applied in electronic product widely.Existing holding wire end generally all is provided with joint, described joint is made up of sleeve pipe, attaching nut, and attaching nut's activity is fixed on an end of sleeve pipe, after the heart yearn of described holding wire passes sleeve pipe, by the instrument pincers that casing tong is tight, joint and holding wire are fixed together.This joint when mounted, must tool using pincers, otherwise can't joint and holding wire be fixed together, cause the staff very inconvenient when erection joint.And fixing also insecure, usually can holding wire be pulled out in joint because of pullling energetically.

Therefore, the utility model is further improved signal wire joint.

[summary of the invention]

The purpose of this utility model provides a kind of signal wire joint, does not need the instrument pincers when making joint and holding wire fixedly, install easily, and also fixing very firm, can holding wire be come off in joint because of pullling energetically.

For achieving the above object, the utility model adopts following scheme:

A kind of signal wire joint is characterized in that including core body, and the inside of described core body is provided with the through hole that passes the holding wire heart yearn, and the tail end of described core body is provided with a plurality of tapered protrusion, and being with at the front end of core body can be along movable rubber base and the fixed sleeving that moves of core body; The front end of described fixed sleeving is fixed on the tail end of rubber base, is provided with annular boss in the tail end inboard of fixed sleeving, the tapered protrusion of described core body tail end and the annular boss fixed signal line that cooperatively interacts; The front end of wherein said rubber base also is fixed with the attaching nut who links to each other with the external world.

Aforesaid a kind of signal wire joint is characterized in that movable mobile being limited between the projection set on the core body of described rubber base.

Aforesaid a kind of signal wire joint is characterized in that described attaching nut is provided with internal thread, and described attaching nut's tail end inboard is provided with in the groove that boss is stuck in rubber base.

Aforesaid a kind of signal wire joint is characterized in that the front end of described fixed sleeving is provided with the prolongation limit of inner bevel, and described prolongation limit is buckled on the boss of rubber base.

Aforesaid a kind of signal wire joint, the tapered protrusion hangnail that it is characterized in that described core body is at epidermis medial surface that holding wire coated.

The beneficial effects of the utility model are: 1, installation is simple and easy, clamps without any need for instrument during erection joint, has saved the time of installing; 2, structure is fastening; During holding wire, can in joint, not pull when mounted because of the senior general's holding wire of exerting oneself; 3, simple in structure, be convenient to make processing.

[description of drawings]

Below in conjunction with accompanying drawing and embodiment the utility model is elaborated:

Fig. 1 is the utility model stereogram;

Fig. 2 is the utility model structural representation;

Fig. 3 is fixed on schematic diagram on the joint for the utility model holding wire;

Fig. 4 is fixed on the joint by the schematic diagram after pullling for the utility model holding wire;

Fig. 5 is the utility model user mode schematic diagram.

[embodiment]

Shown in Fig. 1～5, a kind of signal wire joint, include core body 1, the inside of described core body 1 is provided with the through hole 3 that passes holding wire 2 heart yearns 20, the tail end of described core body 1 is provided with a plurality of tapered protrusion 4, described tapered protrusion 4 one ends are the rear flank in the epidermis that insertion holding wire 2 is coated, and hangnail comes thereby be difficult for being pulled out at the epidermis medial surface of holding wire 2.Being with at the front end of core body 1 can be along core body 1 movable rubber base 5 and the fixed sleeving 6 that moves, and the front end of described fixed sleeving 6 is fixed on the tail end of rubber base 5.Tail end inboard at fixed sleeving 6 is provided with annular boss 7, the tapered protrusion 4 of described core body 1 tail end and the annular boss 7 fixed signal line 2 that cooperatively interacts, holding wire 2 is clipped between tapered protrusion 4 and the annular boss 7, thereby makes holding wire 2 more firm with being connected of joint; The front end of wherein said rubber base 5 also is fixed with the attaching nut 8 who links to each other with the external world.

In the present embodiment, described rubber base 5 movable mobile being limited between the projection set on the core body 19.Described attaching nut 8 is provided with internal thread 10, and described attaching nut's 8 tail end inboard is provided with in the groove 12 that boss 11 is stuck in rubber base 5.The front end of described fixed sleeving 6 is provided with the prolongation limit 13 of inner bevel, and described prolongation limit 13 is buckled on the boss 14 of rubber base 6.

The utility model is on holding wire during erection joint, clamp without any need for instrument, only need 1 tail end of the core body in the joint is inserted into the epidermis inboard that holding wire 2 ends are coated, tapered protrusion 8 on the core body 1 is propped up into the epidermis of holding wire 2 projection of a plurality of outside protrusions, again with holding wire 2 past post-tensionings, the tail end that drives core body 1 past fixed sleeving 6 moves, when tapered protrusion 4 is pulled in the annular boss 10 of fixed sleeving 3, described holding wire 2 is sandwiched between between tapered protrusion 4 and the annular boss 10, thereby make holding wire 2 fastened, be difficult in joint, coming off.
