Shading ring, the external shield ring has body section and crimp segment, and the crimp segment is set in outside inner shield ring and is pressed together on electricity
On cable outer wall, week is provided with spring inside the cable connector, when cable connector is sheathed on the periphery of cable, the spring pressing
In the body section of external shield ring.
Further, the inner shield ring is closely set on cable, and is directly contacted with the screen layer of cable, while institute
State screen layer and continuously extend and crimp and be fixed between the inner shield ring and the crimp segment of external shield ring.
Further, the body section of the external shield ring is tubular structure with cable connector.
Further, the outer surface of the cable connector is provided with screw thread, the screw thread be at least used to making cable connector with
Female part is fixedly connected.
Further, the cable connector, external shield ring and female part are coaxially disposed.
Further, the female part has the accommodating chamber for accommodating cable connector.
Further, the accommodating chamber and the external structure of cable connector match.
Further, the cable includes core, inner insulating layer, screen layer and the external insulation set gradually from inside to outside
Layer.
Compared with prior art, advantage of the present utility model includes：The shielded cable joint design that the utility model is provided,
By changing the length and structure of external shield ring, the contact area of screen layer and shell is increased, leading for interference signal is improved
Go out efficiency, greatly improve shield effectiveness.

Embodiment
In view of deficiency of the prior art, inventor is able to propose that this practicality is new through studying for a long period of time and largely putting into practice
The technical scheme of type.The technical scheme, its implementation process and principle etc. will be further explained as follows.
The utility model provides a kind of shielded cable joint design of improvement, including cable connector, the cable connector
The periphery of partial cables is set in, and is at least used to cable being fixedly connected on female part；The periphery of the cable is provided with outer
Shading ring, the external shield ring has body section and crimp segment, and the crimp segment is set in outside inner shield ring and is pressed together on electricity
On cable outer wall, week is provided with spring inside the cable connector, when cable connector is sheathed on the periphery of cable, the spring pressing
In the body section of external shield ring.
Referring to Fig. 1, in some specific embodiments, a kind of shielded cable joint design of improvement, including cable
1, core, inner insulating layer, screen layer and external insulation layer that the cable 1 is set gradually from inside to outside, and closely it is set in electricity
Inner shield ring 4 on cable, the inner shield ring 4 is directly contacted with the screen layer 5 of cable, while the screen layer 5 continuously extends
And crimping is fixed between the inner shield ring 4 and external shield ring crimp segment 7, it is preferred that make external screen by applying external pressure
Ring 3, inner shield ring 4 is covered to be in close contact with screen layer 5；
Further, the shell 2 is set in the periphery at cable connector, the shell 2 and is provided with spring 8, works as institute
When stating shell 1 and being set at cable connector, the spring 8 is set in external shield ring body section 6, forms a contact area 9；
In addition, the outside of shell 2 is provided with screw thread, cable can be fixedly connected with female part by the shell.
It is preferred that, body section and the cable connector of the external shield ring can be tubular structure.
