Problems solved by technology

It needs to be further improved: first, because there is no O-ring seal between the inner parts and the main body, it is easy to cause dust or water to enter the box, resulting in unreachable product performance; second, there is a certain threading angle of the shielding ring from top to bottom , when the cable passes through the shielded joint, it can pass through smoothly, but if the cable penetration length is too long, the cable cannot be retracted to a suitable length, and when the cable needs to pass upwards under the anti-shielded cable fixing head, the shielding ring is a reverse angle, the cable cannot pass through normally

Embodiment 1

[0024] Embodiment 1: with reference to attached Figure 1-16 . An anti-shielding metal cable fixing head, comprising a hex nut 8, a first O-ring 7, a main body 6, an inner part 3, a waterproof ring 2 and a tight nut 1, and one side of the mouth of the waterproof ring 2 is provided with a layer of sealing The film 22 of the waterproof ring is designed as an annular groove structure 21 and cooperates with the boss 33 on the inner part; the inside of the main body 6 is equipped with a triangular spring 5; the arc boss 31 on the inner part 3 and the main body 6 The inner arc groove 61 fits; the second O-ring 4 is added between the inner fitting 3 and the main body 6. The bottom 2 of the waterproof ring is made into a bevel 23 and matches the bevel in the interior part 3. Both sides 51 of the triangular spring 5 are inclined planes and the contact position between the triangular spring and the cable is designed as an arc shape 52 . A boss 32 is provided axially on the inner fitt...

Embodiment 2

[0025]Embodiment 2: On the basis of Embodiment 1, an assembly, shielding and sealing method of an anti-shielding metal cable gland includes a hexagonal nut 8, a first O-ring 7, a main body 6, an inner fitting 3, a waterproof ring 2 and a forced Tighten the nut 1, and make a groove 21 on the outside of the waterproof ring 2 to cooperate with the ring-opening discontinuous boss 33 on the inner part 3. When assembling, the annular discontinuous boss 33 on the inner part 3 snaps into the groove 21 on the waterproof ring , to prevent the cable from being pushed out of the main body when the cable passes through the waterproof ring; the annular arc boss 31 on the inner fitting 3 cooperates with the inner arc groove 61 of the main body. When the inner fitting is installed in the main body, the inner fitting 3 The cooperation between the annular arc boss 31 and the inner arc groove 61 of the main body can prevent the inner fittings from falling off and reduce repeated installation duri...

Abstract

The invention relates to an anti-shielding metal cable fixing head and an assembly shielding sealing method. By the anti-shielding metal cable fixing head and the assembly shielding sealing method, a cable can be fixed with a case effectively, the cable and the case can be sealed effectively, simply and conveniently, the time and the labor are saved, a dustproof and waterproof effect can be achieved directly, an in-built piece can be prevented from being separated from a main body, an O-shaped ring between the in-built piece and the main body can be prevented from sliding downwards, and a cable wire can be shielded and guided. The anti-shielding metal cable fixing head comprises a hexagon nut, the O-shaped ring, the main body, the in-built piece, a waterproof ring and a tightening nut, and is characterized in that a closed film is arranged on a surface of an opening of the waterproof ring; an annular groove is formed in the outside of the waterproof ring and is matched with a lug boss on the in-built piece; a triangular spring is arranged in the main body; an arc lug boss on the in-built piece is matched with an arc groove in the main body; and the O-shaped ring is arranged between the in-built ring and the main body.

Description

technical field [0001] The invention relates to a device that can effectively fix the cable and the box body together, ensure an effective seal between the cable and the box body, is easy to operate, saves time and labor, and can directly play the role of dustproof and waterproof and prevent the inner parts from being separated from the box. The falling off between the main bodies prevents the O-ring products between the inner parts and the main body from sliding down. At the same time, it has shielded cables and an anti-shielding metal cable fixing head with a guiding effect on the cables and an assembly shielding sealing method. It is a metal cable. Stationary head manufacturing field. Background technique [0002] CN104362576A, name "An anti-shielding metal cable gland", an anti-shielding metal cable gland, including a tightening nut, a sealing ring, a shielding ring and a main body, characterized in that the sealing ring is in a tubular shape as a whole, and the The sea...
