Examples

As shown in fig. 1, the embodiment discloses an aging-resistant environment-friendly photovoltaic cable, which includes a cable body 1; the two ends of the cable body 1 are respectively provided with a protective device 2. The protective device 2 is used for protecting the end of the cable body 1 from being corroded by external water vapor.

Specifically, as shown in fig. 2 and 3, the protector 2 includes a protecting member, two arc-shaped clamping pieces 9 and a locking ring 8. One end of the two arc-shaped clamping pieces 9 is connected to the protective part, and the two arc-shaped clamping pieces 9 are distributed up and down, so that a clamping space is formed between the two. In addition, one ends of the two arc-shaped clamping sheets 9, which are far away from the protective part, are inclined to one side far away from each other, so that the two arc-shaped clamping sheets 9 are horn-shaped integrally; moreover, the thickness of the arc-shaped clamping pieces 9 is gradually increased from one side close to the protection part to the other side, so that a tapered hole is formed between the two arc-shaped clamping pieces 9 after the two arc-shaped clamping pieces are squeezed and contracted. When the two arc-shaped clamping pieces 9 are subjected to extrusion force, the clamping space contracts, and then the two arc-shaped clamping pieces 9 can clamp the end of the cable body 1. This 8 covers of locking ring are established on the protective member to can remove, be provided with the internal thread on the locking ring 8, then be provided with the external screw thread on the outer wall of two arc centre gripping pieces 9, enable this locking ring 8 to remove to two arc centre gripping pieces 9 during rotatory locking ring 8 on, thereby extrude two arc centre gripping pieces 9, make two arc centre gripping pieces 9 can press from both sides the end of tight cable body 1.

When the cable body 2 is arranged, the end of the cable body 1 penetrates through the two arc-shaped clamping pieces 9 and then extends into the protection part, and then the cable body 1 is clamped tightly through the two arc-shaped clamping pieces 9, so that the whole protection device 2 is fixed at the end of the cable body 1.

In addition, the clamping surfaces of the two arc-shaped clamping pieces 9 are respectively provided with an arc-shaped clamping sealing gasket 10. When the two arc clamping pieces 9 clamp the cable body 1 tightly, the arc clamping sealing gasket 10 can seal the gap between the arc clamping pieces 9 and the cable body 1, so that the protection device is internally provided with a closed space, and the protection effect is improved.

The shielding member comprises a connecting sleeve 3 and an end cap 7. The end cap 7 is screwed with one end of the connecting sleeve 3, and two arc-shaped clamping pieces 9 are arranged at the other end of the connecting sleeve 3. A sealing gasket is arranged between the end cover 7 and the connecting sleeve 3, so that the sealing performance between the end cover and the connecting sleeve can be improved.

As shown in fig. 3, the coupling sleeve 3 is provided with a locking ring mounting part 12, the locking ring mounting part 12 is an annular recessed table formed at an outer surface of the coupling sleeve 3, the locking ring 8 is mounted on the locking ring mounting part 12, and the locking ring 8 is in a clearance fit with the locking ring mounting part 12, so that the locking ring 8 can move on the locking ring mounting part 12 and can be screwed to the two arc-shaped clamping pieces 9 when the locking ring 8 is rotated. By providing the locking ring mounting portion 12, the locking ring 8 does not come off the connecting sleeve 3. When the locking ring 8 needs to be installed in the production process, the two arc-shaped clamping pieces 9 are extruded through external force to shrink, and then the locking ring 8 is screwed in.

In addition, an installation cavity 4 is formed between the end cover 7 and the connecting sleeve 3, and a plugging structure is arranged in the installation cavity 4. Specifically, as shown in fig. 2 and 3, the blocking structure comprises a blocking head 5 and a spring 6. One end of the spring 6 is connected with the blocking head 5, the other end of the spring is connected with the bottom of the end cover 7, the end section of the cable body 1 props against the blocking head 5, and the blocking head 5 can be attached to the end section of the cable body 1 more tightly through the restoring force of the spring 6.

In order to improve the sealing effect, the sealing head 5 is provided with a sealing gasket 11, and the cross section of the end head of the cable body 1 abuts against the sealing gasket 11. This shutoff gasket 11 is rubber materials, consequently can be better with the end cross-section laminating of cable body 1, prevents that the cable core of cable body 1 from exposing outward.

During implementation, the end of the cable body 1 extends into the connecting sleeve 3 from between the two arc-shaped clamping pieces 9, the cross section of the end of the cable body 1 is made to press the plugging gasket 11 on the plugging head 5, then the locking ring 8 is screwed, the locking ring 8 extrudes the two arc-shaped clamping pieces 9, and the two arc-shaped clamping pieces 9 clamp the cable body 1, as shown in fig. 4.
