Drawings

Fig. 1 is a schematic view of the overall three-dimensional structure of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

In the description of the present invention, it should be understood that the directions or positional relationships indicated by "front", "back", "left", "right", "up", "down", etc. in the terms are based on the directions or positional relationships shown in the drawings, and it is only for convenience of description that the present invention and simplified description, rather than indicating or suggesting that the indicated device or element must have a specific direction, and constructing and operating in a specific direction, and therefore cannot be understood as a limitation of the present invention, the technical solutions of the embodiments of the present invention may be combined, and the technical features of the embodiments may also be combined to form a new technical solution.

Please refer to fig. 1:

the fixed plug bush 2 of 1 both ends spiro union of a grafting section of thick bamboo, fixed plug bush 2 surface is provided with the support bar 3 of two circumference arrays, and 3 inner walls of support bar are fixed and are provided with three fixture block 4, and relative fixture block 4 phase-matches on two support bars 3, and 4 terminal surfaces of fixture block are provided with rubber stationary blade 5, and 5 terminal surfaces of rubber stationary blade are convex, and the cover is equipped with ribbon 6 on 3 outer walls of two support bars.

The utility model discloses a working process and principle:

1. the method comprises the following steps of sleeving a photovoltaic cable with a fixed plug bush 2 and a plug barrel 1, and connecting two photovoltaic cables, namely, screwing the plug bush at two ends of the plug barrel 1, wherein the connection mode is a common connection mode in the prior art;

2. the photovoltaic cable outside the fixing plug bush 2 is straight, the photovoltaic cable passes through the rubber fixing pieces 5 on the clamping blocks 4 and is wound on the outer sides of the supporting bars 3 through the binding belts 6 to be tightened, the supporting bars 3 deform towards the inner side in the tightening process of the binding belts 6, the rubber fixing pieces 5 tightly cling to the photovoltaic cable, the clamping blocks 4 prevent the photovoltaic cable from shifting left and right, and after the binding belts 6 are tightened, the photovoltaic cable is linear, so that even if the supporting bars 3 are locally bent due to the distribution problem of the photovoltaic cable, the bending state of terminals is reduced, and the circuits are not easily broken in the operation process;

3. according to the diameter of photovoltaic cable, can be suitable increase or reduce the quantity of fixture block 4, ribbon 6, support bar 3, for example when the diameter is great, the quantity of support bar 3 can be three or even four and be the circumference array, fixture block 4 is 5, 6 etc. ribbon 6 generally adopts more than two can more firm.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
