[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] The present invention provides the following embodiments to describe the present invention in detail:

[0023] Example

[0024] refer to Figure 1-5 As shown, a plastic bracket for automobile wiring harness includes:

[0025] like Figure 1 As shown, the bracket body 1 is made of plastic, and a through cavity 11 is arranged along its axis. Two first through holes 12 are symmetrically arranged on the outer wall of one end of the bracket body 1, and the two first through holes 12 are connected to the cavity 11. Figure 3 As shown, two card slots 13 are symmetrically arranged on the inner side wall of the other end of the bracket body 1, and the two card slots 13 constitute a part of the cavity 11. Preferably, the card slots 13 can be set as Figure 3 T-groove as shown;

[0026] like Figure 1 As shown, the bayonet 2 is also made of plastic and is located in the cavity 11. A second through hole 21 is provided at one end of the bayonet 2. The second through hole 21 penetrates the bayonet 2. Two first spring pieces 22 are provided below the second through hole 21. The outer sides of the two first spring pieces 22 are provided with first protrusions 23. The two first protrusions 23 are adapted to the two slots 13. Two second spring pieces 24 are provided below the two first spring pieces 22. The outer sides of the two second spring pieces 24 are provided with second protrusions 25. The two second protrusions 25 are adapted to the mounting grooves on the ribs of the automobile. It should be noted that the first spring piece 22 and the second spring piece 24 both have a certain elasticity and can be restored after deformation.

[0027] The cable tie 3 is used to cooperate with the bracket body 1 and the bayonet 2 to fix the automobile wiring harness.

[0028] Specifically, Figure 4 As shown, when the bayonet 2 is located in the cavity 11, the cable tie 3 can pass through one of the first through holes 12 and the second through holes 21 in sequence, and then pass through another first through hole 12 to form a limiting space I for fixing the wiring harness.

[0029] In the above structure, the orthographic projection of the line between the two first through holes 12 on the horizontal plane intersects with the orthographic projection of the line between the two first spring sheets 22 on the water surface, and the orthographic projection of the line between the two first through holes 12 on the horizontal plane can be orthogonal to the orthographic projection of the line between the two second spring sheets 24 on the water surface. During installation, first fix the bayonet 2 in the mounting groove on the automobile rib plate through the two second protrusions 25, and then insert the bracket body 1 from the upper end of the bayonet 2 and press the bracket body 1 downward so that the second through hole 21 is located in the cavity 11. It should be noted that at this time, the first protrusion 23 on the two first spring sheets 22 cannot be engaged with the slot 13. When the second through hole 21 and the two first through holes 12 are located in the same horizontal plane, rotate the bracket body 1 so that the cable tie 3 can pass through the second through hole 21 and the two first through holes 12. After the cable tie 3 is put on, pull the bracket body 1 upward until the first protrusion 23 is engaged with the slot 13, place the wiring harness in the cable tie 3 and tighten it to form a Figure 4 The limited space Ⅰ.

[0030] In order to meet the needs of wire harnesses of different diameters, two third through holes 14 are symmetrically arranged on the outer wall of the bracket body 1. The two third through holes 14 are located below the two first through holes 12 and are both connected to the cavity 11. When the pin 2 is located in the cavity 11, the cable tie 3 can pass through one of the third through holes 14 and the second through hole 21 in sequence, and then pass through the other third through hole 14 to form a limiting space II for fixing the wire harness.

[0031] Specifically, the orthographic projection of the line between the two third through holes 14 on the horizontal plane intersects with the orthographic projection of the line between the two first spring plates 22 on the water surface, and the orthographic projection of the line between the two third through holes 14 on the horizontal plane may be orthogonal to the orthographic projection of the line between the two second spring plates 24 on the water surface. When used specifically, the operation method is the same as the method for forming the limit space I, and will not be repeated.

[0032] In order to improve the service life, the outer sides of the two first spring pieces 22 are provided with first reinforcing ribs 26, and the other ends of the two first reinforcing ribs 26 are fixed to the first protrusion 23; the outer sides of the two second spring pieces 24 are provided with second reinforcing ribs 27, and the other ends of the two second reinforcing ribs 27 are fixed to the second protrusion 25.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
