Description

Structure for reducing shielding part number by cable tension

Technical Field

The utility model relates to a cable equipment field specifically is a structure that utilizes cable tension to reduce shielding part quantity.

Background

The existing shielding structure is mostly in spring plate type contact, or the shielding ring is in contact with the spring plate of the shielding cover after being pressed and connected, and the shielding cover is in contact with the metal shell; or the shell is contacted with the elastic sheet of the shielding cover to achieve the shielding effect. The shielding structure adopts the mode that the shielding ring is pressed and then is contacted with the elastic sheet of the shielding cover, one more part is added in the contact mode, the cost is higher, and an assembly process is added; and the shielding mode that the shielding cover is directly adopted to press the shielding cable and then the elastic sheet of the shielding cover is contacted with the shell is adopted, the space of the shielding cover is larger (the space of a pressing area and the area of the elastic sheet is limited), the contact quantity of the elastic sheet is limited, and the shielding effect is low.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model discloses an utilize cable tension to reduce structure of shielding part quantity.

The technical scheme of the utility model is that: the utility model provides an utilize cable tension to reduce structure of shielding part quantity, the cable comprises a cable, the cable top is equipped with plug shell subassembly, plug shell subassembly is including the gluey core that is located cable one end, it is equipped with the plug shell to glue the core outward, the plug shell is located to glue the core and is equipped with the screw thread outside the part that is close to the cable, the outer one side of cable is equipped with the body of wire sealing, the cable is equipped with the tail-hood outward with the body of wire sealing, the cable is equipped with the tail pipe outward, the cable is equipped with the shield ring outward in the tail pipe, the terminal surface of shield ring and tail pipe is equipped with the interval in the lax condition of cable, tail pipe one end is located between the body of wire.

Furthermore, the shielding ring is in crimping connection on the outer surface of the cable, an outward convex ring is arranged on one side, close to the wire sealing body, of the shielding ring, the distance from the convex ring to the end face of the cable is larger than the distance from the convex ring to the end face of the rubber core, and the side faces of the end faces in the convex ring and the tail pipe are in contact under the condition that the cable is under tension. (

Further, the wire sealing body is located between the end face of the tail pipe and the tail cover.

Furthermore, the middle parts of the shielding ring and the rubber core in the tail pipe are provided with O-shaped rings.

The utility model discloses an useful part: after the shielding ring and the shielding cable are in compression joint, the end face of the shielding ring is in contact with the end face of the shell by using the tension of the cable after the cable is assembled on the plug shell.

Drawings

Fig. 1 is a schematic structural view of the cable in a tensioned state according to the present invention;

fig. 2 is a schematic structural view of the cable in a loose state according to the present invention;

wherein: 1. the cable comprises a cable body, 2, a rubber core, 3, a plug shell, 4, threads, 5, a wire sealing body, 6, a tail cover, 7, a tail pipe, 8, an end face, 9, a shielding ring, 91, a convex ring, 10 and an O-shaped ring.

Detailed Description

In order to deepen the understanding of the present invention, the following detailed description is given with reference to the accompanying drawings, which are only used for explaining the present invention and do not constitute a limitation to the protection scope of the present invention.

As shown in fig. 1-2, a structure for reducing the number of shielding members by using cable tension comprises a cable 1, a plug housing assembly is arranged at the top end of the cable 1, the plug housing assembly comprises a rubber core 2 positioned at one end of the cable, a plug housing 3 is arranged outside the rubber core 2, threads 4 are arranged outside the part of the plug housing 3 positioned at the rubber core 2 close to the cable 1, a wire sealing body 5 is arranged at one side outside the cable 1, tail covers 6 are arranged outside the cable 1 and the wire sealing body 5, the wire sealing body 5 is positioned between an end face 8 of the tail pipe 7 and the tail cover 6, a tail pipe 7 is arranged outside the cable 1, a shielding ring 9 is arranged outside the cable 1 in the tail pipe 7, the shielding ring 9 is pressed on the outer surface of the cable 1, a distance is arranged between the shielding ring 9 and the end face of the tail pipe 7 when the cable 1 is loose, an outward convex ring 91 is arranged at one side of the shielding ring 9 close to the, therefore, when the tail pipe is screwed, the cable is bent, since tension is generated, the convex ring 91 is contacted with the side surface of the end surface 8 in the tail pipe 7 under the condition that the cable is under tension, one end of the tail pipe 7 is positioned between the wire sealing body 5 and the tail cover 6, the other end of the tail pipe 7 is positioned between the plug shell 3 and the cable 1, the tail pipe 7 is provided with threads matched with the plug shell 3, and the shielding ring 9 in the tail pipe 7 and the middle part of the rubber core 2 are provided with O-shaped rings 10.

The tail pipe and the shell are screwed tightly, so that the cable is compressed, the cable is bent due to compression to generate tension, and the tension forces the shielding ring to be in close contact with the end face, so that reliable electric connection is realized.
