DETAILED DESCRIPTION

[0019] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] In this article, the terms "upper, lower, inside, outside" and the like are established based on the positional relationships shown in the drawings. The corresponding positional relationships may also change depending on the drawings, and therefore cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" and the like are merely used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0021] Example

[0022] like Figure 1-4 As shown, a wire harness fixing seat for facilitating wire fixing includes a base 2, a cover plate 1 detachably arranged on the base 2, and a sleeve 14 is arranged between the base 2 and the cover plate 1; wherein, self-locking components are arranged on both sides of the sleeve 14, and the self-locking components include first elastic pieces 7 arranged on the sleeve 14 at intervals along the circumferential direction, one end of the first elastic piece 7 is installed on the sleeve 14, and the other end of the first elastic piece 7 is provided with a first wire fixing surface.

[0023] Specifically, the base 2 is connected to the external component, and an installation space for the sleeve 14 is formed between the base 2 and the cover plate 1. Preferably, the installation space formed between the base 2 and the cover plate 1 is an interference fit with the sleeve 14, and the wiring harness passes through the sleeve 14 and is fixed by a first spring piece 7 arranged at intervals along the circumferential direction. The first spring piece 7 uses its own elastic force to press the first wire fixing surface tightly against the wiring harness to fix the wiring harness. No additional operation is required, and when the specifications and quantity of the wiring harness do not change greatly, the range of variation of the elastic force is small, and it is not easy for the force acting on the wiring harness to be too large or too small.

[0024] Furthermore, the cover plate 1 is movably provided with a push rod 5, one end of the push rod 5 is connected to a connecting plate 10, and both sides of the connecting plate 10 are connected to connecting rods 11 by rotating shafts;

[0025] An opening groove is provided on one side of the sleeve 14 close to the cover plate 1. Two expansion tubes 12 are movably provided in the sleeve 14. The connecting rod 11 is hinged to the expansion tube 12. The cover plate 1 has a guiding effect on the push rod 5. The push rod 5 is pushed, and the push rod 5 drives the connecting rod 11 to deflect, thereby driving the expansion tube 12 to open the first elastic sheet 7, which is convenient for the entry of the wiring harness.

[0026] Furthermore, a first limit seat 15 is provided on the outer side of the cover plate 1, and a second limit seat 9 is provided on the inner side of the cover plate 1. The first limit seat 15 is used to limit the stroke of the push rod 5. When the push rod 5 abuts against the cover plate 1, the connecting rod 11 is in a horizontal state. At this time, the connecting rod 11 is in a horizontal dead point state, and the force received by the push rod 5 is greatly reduced, which is convenient for control. The second limit seat 9 is used to limit the connecting plate 10 to prevent the connecting rod 11 from forming a vertical dead point.

[0027] Furthermore, an elastic member 6 is provided between the first limiting seat 15 and the push rod 5. The elastic member 6 facilitates the reset of the push rod 5.

[0028] Furthermore, stepped grooves are provided on both sides of the sleeve 14, and the stepped grooves include a first step surface and a second step surface. The first spring clip 7 is provided on the first step surface, and the second spring clip 8 is provided on the second step surface at intervals along the circumferential direction. One end of the second spring clip 8 is installed on the second step surface, and the other end of the second spring clip 8 is provided with a second fixing line surface. The second spring clip 8 is used to increase the stability of the fixing line.

[0029] Furthermore, the first wire fixing surface and / or the second wire fixing surface are provided with a wire fixing groove 13, and the cross-sectional shape of the wire fixing groove 13 is any one of a triangle, a trapezoid, and an arc. The wire fixing groove 13 is used to increase the contact surface between the first wire fixing surface and / or the second wire fixing surface and the wire harness, increase the force between the first wire fixing surface and / or the second wire fixing surface and the wire harness, and thus increase the stability of the fixing wire.

[0030] Further, the base 2 is provided with a mounting hole 3, and a fastener 4 is provided between the base 2 and the cover plate 1, and the base 2 and the cover plate 1 are connected by the fastener 4. The mounting hole 3 is used to mount the base 2 on an external component, and the fastener 4 is preferably a bolt.

[0031] The above-mentioned technical features can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
