Description

Technical Field

[0001] The present invention relates to the technical field of wire harness brackets, and specifically to a wire harness fixing bracket. Background Art

[0002] An automotive wire harness is the network main body of an automotive circuit. Without a wire harness, there would be no automotive circuit. Generally, an automotive wire harness refers to components formed by crimping contact terminals (connectors) made of copper material with wires and cables, and then molding an insulator outside or adding a metal housing, etc., and bundling the wire harness to form a component for connecting circuits.

[0003] Chinese Patent CN119009827A discloses a conveniently adjustable automotive wire harness bracket and its using method, including a bottom placement support plate, a bottom placement mounting block plate fixedly installed at the bottom of the bottom placement support plate, and bottom placement strip blocks fixedly installed at the top of the bottom placement support plate.

[0004] Although the wire harness bracket of the above patent can fix the automotive wire harness, when the automotive wire harness is installed and used inside an automobile, a large amount of heat is generated during the operation of internal components of the automobile. While the bracket fixes the wire harness, it is difficult to conduct and dissipate the heat of the wire harness. The accumulation of high-temperature heat may cause the insulating material on the surface of the wire harness to undergo thermal-oxidative aging, resulting in the breakage of its molecular chain, embrittlement and cracking of the material, and loss of insulating performance, reducing the service life of the automotive wire harness. Moreover, after the insulating layer of the wire harness is damaged, adjacent wires may come into direct contact, causing a short circuit or even an electric arc, and in extreme cases, the wire harness may melt, having an adverse impact on normal driving. Summary of the Invention

[0005] To solve the technical problems in the background art, the present invention proposes a wire harness fixing bracket.

[0006] A wire harness fixing bracket proposed by the present invention includes a base. Two oppositely arranged stoppers are installed on the upper end surface of the base to form a wire harness shuttle channel. A limiting plate is installed at the bottom of the inner side surface of the stopper. A partition plate, an upper pressing heat dissipation component, and a lower supporting heat dissipation component are arranged between the two limiting plates. The wire harness shuttle channel is divided into an upper channel and a lower channel by the partition plate. The upper pressing heat dissipation component presses and dissipates heat from the wire harness in the upper channel, and the lower supporting heat dissipation component supports and dissipates heat from the wire harness in the lower channel from below.

[0007] The stoppers are installed on the base, and the formed wire harness shuttle channel provides a placement space for the wire harness. The limiting plate is at the bottom of the inner side surface of the stopper, and is used to assist in fixing and positioning the partition plate, the upper pressing heat dissipation component, and the lower supporting heat dissipation component. The partition plate divides the channel into upper and lower layers, realizing hierarchical management of the wire harness, facilitating heat dissipation and fixing. The upper pressing heat dissipation component presses and covers the upper-layer wire harness from above, not only fixing the wire harness, but also dissipating heat using its own structure. The lower supporting heat dissipation component supports the lower-layer wire harness from below and dissipates heat.

[0008] The stopper located on the left side is fixedly installed on the upper left side of the base. The lower end of the stopper located on the right side is slidably assembled with the upper right side of the base, so as to adjust the distance between the two stoppers to adapt to wire harnesses of different quantities and specifications, facilitating actual wiring and maintenance operations. A connecting rod is installed on the stopper located on the right side. When the distance between the two stoppers gradually shortens, the free end of the connecting rod is inserted into and fixed to the stopper on the left side by bolts, thus completing the fastening work after wiring.

[0009] A cushion block is installed at the bottom of one end of the base. The other end of the base has an extension plate, which has a bending section and a horizontal section. The two ends of the bending section are respectively connected to the base and the horizontal section. The bottom of the horizontal section is flush with the lower end of the cushion block, and the horizontal section is fixed to the installation surface by screws. The lower part of the base is arched by the cushion block and the extension plate to form a lower-layer heat dissipation bin for the lower-support heat dissipation component to dissipate heat, enhancing the heat dissipation effect.

[0010] As a further optimized solution of the present invention, the upper-pressure heat dissipation component includes a pressing plate, a first heat dissipation fin, and a first heat conduction sheet. The pressing plate is arranged above the upper-layer channel and is detachably assembled with the stopper. The first heat dissipation fin is installed on the upper end surface of the pressing plate and extends upward. The first heat conduction sheet is installed on the lower end surface of the pressing plate and extends downward, dividing the upper-layer channel into several single-wire harness channels.

[0011] The detachable connection between the pressing plate and the stopper is convenient for installation and disassembly, facilitating the adjustment and maintenance of the wire harness. The first heat dissipation fin extends upward, increasing the contact area with the air, accelerating heat dissipation, and improving the heat dissipation efficiency. The first heat conduction sheet extends downward, dividing the upper-layer channel into multiple single-wire harness channels, arranging the wire harnesses separately to avoid mutual entanglement. At the same time, it can directly contact the wire harness, conduct the heat generated by the wire harness to the pressing plate, and then dissipate the heat through the first heat dissipation fin, effectively reducing the temperature of the upper-layer wire harness.

[0012] As a further optimized solution of the present invention, the number of the first heat conduction sheets is multiple, and the multiple first heat conduction sheets are equidistantly distributed along the length direction of the pressing plate to form multiple single-wire harness channels. The lower end of the first heat conduction sheet is inserted into and can conduct heat with the upper end of the partition plate.

[0013] The multiple first heat conduction sheets equidistantly distributed can more evenly divide the upper-layer channel, ensuring that the wire harnesses in each single-wire harness channel can be effectively fixed and dissipated heat. The lower end of the first heat conduction sheet is inserted into and can conduct heat with the upper end of the partition plate. On the one hand, it enhances the support and positioning effect on the upper-layer wire harness. On the other hand, the heat of the upper-layer wire harness can be conducted to the partition plate through the first heat conduction sheet and then transferred to the lower-support heat dissipation component by the partition plate, realizing the heat transfer between the upper and lower heat dissipation components and further improving the overall heat dissipation performance.

[0014] As a further optimized solution of the present invention, heat-conducting elastic pieces are installed on both sides of the first heat-conducting sheet. The heat-conducting elastic pieces are arc-shaped sheets, and the concave arc surface of the heat-conducting elastic piece is fitted to the surface of the wire harness in the adjacent single wire harness channel;

[0015] The arc design of the heat-conducting elastic piece enables it to better fit the surface of the wire harness, increasing the contact area with the wire harness and improving the heat-conducting effect. It can more effectively conduct the heat of the wire harness to the first heat-conducting sheet and then dissipate it through the first heat-dissipating fins, further enhancing the heat-dissipating capacity of the upper pressing heat-dissipating component for the upper-layer wire harness, ensuring that the wire harness maintains a lower temperature during operation, and reducing the damage to the insulating material caused by high temperature.

[0016] As a further optimized solution of the present invention, a guiding plate is installed on the upper end surface of the pressing plate. A guiding groove adapted to the guiding plate is opened at the bottom of the blocking block. The two blocking blocks are respectively assembled at both ends of the guiding plate and locked by fasteners; a pressing groove is opened on the lower end surface of the pressing plate. The number of pressing grooves is the same as and corresponds one by one to the number of single wire harness channels. The pressing groove is an arc-shaped groove and is adapted to the wire harness;

[0017] The cooperation of the guiding plate and the guiding groove plays a guiding role when installing the pressing plate, ensuring that the pressing plate is accurately installed between the two blocking blocks. After being locked by fasteners, the connection between the pressing plate and the blocking block is firm. The pressing grooves on the lower end surface of the pressing plate correspond one by one to the single wire harness channels and are arc-shaped, adapting to the shape of the wire harness, and can better press the wire harness to prevent the wire harness from shaking or shifting during vehicle driving, further improving the fixing effect on the wire harness.

[0018] As a further optimized solution of the present invention, the lower supporting heat-dissipating component includes a heat-conducting pad, a heat-conducting gasket, a heat-conducting plate, a second heat-conducting sheet and second heat-dissipating fins. The heat-conducting pad is installed at the bottom of the base and extends upward to the bottom of the lower layer channel and installs the heat-conducting gasket. The wire harness is supported by the heat-conducting gasket. The heat-conducting plate is detachably installed at the bottom of the base and is closely combined with the heat-conducting pad. The second heat-conducting sheet is installed on the upper end surface of the heat-conducting plate and penetrates through the heat-conducting pad and extends into the lower layer channel, dividing the lower layer channel into several single wire harness channels. The second heat-dissipating fins are installed on the lower end surface of the heat-conducting plate and extend downward;

[0019] An installation groove adapted to the heat-conducting plate is opened on the lower end surface of the base. The heat-conducting pad is installed on the top inner wall of the installation groove, and there is a gap between both ends of the heat-conducting pad and the inner walls on both sides of the installation groove to form a clamping groove. Upper parts at both ends of the heat-conducting plate have protrusions adapted to the clamping groove. A groove adapted to the heat-conducting pad is formed between the two protrusions, so as to closely fit between the heat-conducting plate and the heat-conducting pad. The heat-conducting plate is clamped and connected with the clamping groove and fixed by screws, realizing the quick assembly of the heat-conducting plate and the base;

[0020] The heat-conducting pad is installed at the bottom of the base, extends upward and installs a heat-conducting gasket. While providing support for the lower-layer wire harness, it can conduct the heat of the wire harness. The heat-conducting plate is tightly combined with the heat-conducting pad. Through the cooperation of the installation groove, the card slot and the protrusion, quick installation is achieved, ensuring the structural stability. The second heat-conducting sheet divides the lower-layer single wire harness channel, conducts heat while fixing the wire harness. The second heat-dissipating fin extends downward, increasing the heat-dissipating area, and dissipates the heat conducted by the heat-conducting plate into the surrounding environment, effectively reducing the temperature of the lower-layer wire harness.

[0021] As a further optimized solution of the present invention, the number of the second heat-conducting sheets is multiple, and the multiple second heat-conducting sheets are equidistantly distributed along the length direction of the heat-conducting plate to form multiple single wire harness channels, and a heat-conducting gasket is arranged at the bottom of each single wire harness channel to support the wire harness;

[0022] The multiple second heat-conducting sheets evenly divide the lower-layer channel, making the lower-layer wire harness arranged neatly and orderly, avoiding wire harness entanglement. The heat-conducting gasket at the bottom of each single wire harness channel not only supports the wire harness, but also conducts the heat of the wire harness to the second heat-conducting sheet and the heat-conducting pad, and then dissipates it through the heat-conducting plate and the second heat-dissipating fin, enhancing the heat dissipation and fixing effect on the lower-layer wire harness.

[0023] As a further optimized solution of the present invention, the second heat-conducting sheet includes a first part, a second part and a third part arranged in sequence from top to bottom. The widths of the first part, the second part and the third part increase in sequence. The upper end of the first part is inserted into the lower end of the partition board and can conduct heat. The two sides of the second part are concave arc surfaces and are attached to the surface of the wire harness in the adjacent single wire harness channel. The third part is inserted and assembled with the base and the heat-conducting pad;

[0024] The first part is inserted into the partition board and conducts heat, realizing the heat transfer between the upper and lower heat dissipation components, further improving the overall heat dissipation effect. The concave arc surface of the second part fits the surface of the wire harness, increasing the contact area with the wire harness, improving the heat conduction efficiency, and better conducting the heat of the wire harness. The third part is inserted and assembled with the base and the heat-conducting pad, enhancing the stability of the second heat-conducting sheet, ensuring that it will not displace during the process of fixing the wire harness and conducting heat, and also contributing to the heat conduction between components.

[0025] As a further optimized solution of the present invention, through holes adapted to the third part are provided on both the heat-conducting pad and the base. The through holes are arranged between two adjacent single wire harness channels, and the outer surface of the third part is slidably inserted into the inner wall of the through hole;

[0026] The setting of the through hole facilitates the installation of the third part with the heat-conducting pad and the base, making the installation more accurate. The way of sliding insertion can not only ensure the tight connection of the third part with other components, but also facilitate disassembly and replacement when needed.

[0027] As a further optimized solution of the present invention, stable grooves adapted to the wire harness are provided on both the upper and lower end faces of the partition plate. The number of stable grooves is multiple and they are evenly distributed along the length direction of the partition plate. A jack is provided on the partition plate between two adjacent stable grooves. The lower heat conduction part of the upper pressing heat dissipation component and the upper heat conduction part of the lower supporting heat dissipation component both extend into the jack and are in contact with each other;

[0028] The stable grooves play a role in limiting the wire harness, preventing the wire harness from moving horizontally in the upper and lower layer channels, further enhancing the fixing effect on the wire harness. The design of the jack enables the heat conduction parts of the upper pressing heat dissipation component and the lower supporting heat dissipation component to be in contact with each other, promoting the conduction of heat between the two components, achieving more efficient heat dissipation, ensuring that the overall temperature of the wire harness is effectively controlled, and extending the service life of the wire harness.

[0029] The wire harness fixing bracket proposed by the present invention has the following beneficial effects:

[0030] (1) By setting the upper pressing heat dissipation component and the lower supporting heat dissipation component, all-round heat dissipation of the wire harness in the upper and lower layer channels is realized. The first heat dissipation fins in the upper pressing heat dissipation component increase the heat dissipation area, the first heat conduction sheet conducts the heat of the wire harness out, and the heat conduction elastic sheet fits on the surface of the wire harness to enhance the heat conduction effect. The second heat dissipation fins of the lower supporting heat dissipation component dissipate heat, and the heat conduction pad, heat conduction gasket, heat conduction plate and second heat conduction sheet work together to conduct and dissipate the heat of the lower layer wire harness. Then, through the jacks at the upper and lower ends of the partition plate, the heat conduction parts of the upper pressing heat dissipation component and the lower supporting heat dissipation component are in contact with each other, further improving the overall heat dissipation efficiency, effectively reducing the temperature of the wire harness, slowing down the thermal oxygen aging of the insulating material, and extending the service life of the wire harness;

[0031] (2) The partition plate divides the wire harness shuttle channel into an upper layer channel and a lower layer channel. Cooperating with the upper pressing heat dissipation component and the lower supporting heat dissipation component, it provides a stable fixing environment for the wire harness. The pressing plate of the upper pressing heat dissipation component presses and fixes the upper layer wire harness through the pressing groove. The first heat conduction sheet divides the upper layer channel into multiple single wire harness channels, making the wire harness arranged neatly and orderly. The lower supporting heat dissipation component supports the wire harness through the heat conduction gasket, and the second heat conduction sheet divides the lower layer single wire harness channels to ensure the stability of the lower layer wire harness. The stable grooves on the upper and lower end faces of the partition plate further limit the wire harness, preventing the wire harness from shaking and shifting during vehicle driving, ensuring the stability of the wire harness connection, and reducing circuit failures caused by wire harness loosening;

[0032] (3) The heat conduction plate of the lower supporting heat dissipation component and the base are quickly assembled through the cooperation of the installation groove, card slot and protrusion. During installation, only need to align the protrusion of the heat conduction plate with the card slot and snap it, and then fix it with screws. The pressing plate of the upper pressing heat dissipation component and the block are cooperated through the guide plate and guide groove and locked with fasteners. The installation and disassembly are convenient. The overall structure design is reasonable, and the installation of each component is convenient, improving the assembly efficiency of the wire harness fixing bracket, reducing the installation difficulty, and being suitable for large-scale production and installation operations.

Examples of the embodiments are shown in the drawings, where the same or similar reference signs denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0042] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may mean that the first feature is directly above or obliquely above the second feature, or simply indicates that the first feature has a higher horizontal height than the second feature. The first feature being "under", "beneath" and "underneath" the second feature may mean that the first feature is directly below or obliquely below the second feature, or simply indicates that the first feature has a lower horizontal height than the second feature.

[0043] In the operation of devices such as modern automobiles, the stable fixation and effective heat dissipation of wire harnesses are crucial. The wire harness fixing bracket of the present invention is designed to address the deficiencies of existing brackets in terms of heat dissipation and fixation. Through its unique structure and the coordinated operation of various components, it achieves the efficient fixation and heat dissipation of wire harnesses. The specific implementation is as follows:

[0044] As Figure 1 shown, this wire harness fixing bracket uses the base 1 as the basic support component. On the upper end face of the base 1, two oppositely arranged stoppers 2 are installed, and a wire harness shuttle channel is formed between them, providing a placement space for the wire harness. The limiting plates 3 installed at the bottom of the inner side of the stoppers 2 play an auxiliary fixing and positioning role for the subsequent installation of the partition plate 4, the upper pressing heat dissipation component 5, and the lower supporting heat dissipation component 6;

[0045] The partition plate 4 is located between the two limiting plates 3, dividing the wire harness shuttle channel into an upper channel and a lower channel. This layered design helps to classify and manage the wire harnesses, and at the same time creates conditions for achieving layered heat dissipation;

[0046] In the upper channel, the upper pressing heat dissipation component 5 presses and dissipates heat from the wire harnesses therein; in the lower channel, the lower supporting heat dissipation component 6 supports and dissipates heat from the wire harnesses. In this way, all-round heat dissipation and stable fixation of wire harnesses at different levels are achieved.

[0047] As Figure 2 and Figure 3 shown, the upper pressing heat dissipation component 5 includes a pressing plate 51, a first heat dissipation fin 52, and a first heat conducting sheet 53. The pressing plate 51 is arranged above the upper channel and is detachably assembled with the stopper 2, which is convenient for operation when the wire harness needs to be adjusted or maintained. A guiding plate 55 is installed on the upper end face of the pressing plate 51, and a guiding groove 56 adapted to it is opened at the bottom of the stopper 2. When installing the pressing plate 51, the guiding plate 55 cooperates with the guiding groove 56 to play a guiding role, ensuring that the pressing plate 51 is accurately installed between the two stoppers 2, and then is locked by fasteners to make the connection between the pressing plate 51 and the stopper 2 firm.

[0048] As Figure 2As shown in the figure, the first heat dissipation fin 52 is installed on the upper end surface of the pressing plate 51 and extends upward. Its main function is to increase the contact area with air, accelerate heat dissipation, and thus improve the heat dissipation efficiency. A plurality of first heat conduction sheets 53 are equally spaced along the length direction of the pressing plate 51. These first heat conduction sheets 53 are installed on the lower end surface of the pressing plate 51 and extend downward, dividing the upper layer channel into several single wire harness channels. The lower end of each first heat conduction sheet 53 is inserted into the upper end of the partition plate 4 and can conduct heat, which not only enhances the support and positioning effect on the upper layer wire harness, but also transfers the heat of the upper layer wire harness to the first heat dissipation fin 52 for heat dissipation. At the same time, it can be conducted to the partition plate 4 through the first heat conduction sheet 53, and then transferred to the lower support heat dissipation assembly 6, realizing the heat transfer between the upper and lower layer heat dissipation assemblies and improving the overall heat dissipation performance.

[0049] As Figure 3 shown, heat conduction elastic sheets 54 are installed on both sides of the first heat conduction sheet 53. The heat conduction elastic sheets 54 are arc-shaped sheets, and their concave arc surfaces are in contact with the surface of the wire harness in the adjacent single wire harness channel. This design increases the contact area with the wire harness, can more effectively conduct the heat of the wire harness to the first heat conduction sheet 53, and then dissipate it through the first heat dissipation fin 52, further enhancing the heat dissipation ability of the upper pressing heat dissipation assembly 5 for the upper layer wire harness. At the same time, pressing grooves 57 are opened on the lower end surface of the pressing plate 51. The number of pressing grooves 57 is the same as and corresponds one by one to the number of single wire harness channels. The pressing grooves 57 are arc-shaped grooves, which are adapted to the shape of the wire harness, can better press the wire harness, prevent the wire harness from shaking or shifting during vehicle driving, and improve the fixing effect on the wire harness.

[0050] As Figure 2 and Figure 4 shown, the lower support heat dissipation assembly 6 is composed of a heat conduction pad 61, a heat conduction gasket 62, a heat conduction plate 63, a second heat conduction sheet 64 and a second heat dissipation fin 65. The heat conduction pad 61 is installed in the installation groove 8 at the bottom of the base 1, extends upward to the bottom of the lower layer channel, and a heat conduction gasket 62 is installed on its surface for supporting the wire harness. The heat conduction plate 63 is detachably installed at the bottom of the base 1 and is tightly combined with the heat conduction pad 61;

[0051] Specifically, as Figure 4 shown, an installation groove 8 is opened on the lower end surface of the base 1. The heat conduction pad 61 is installed on the top inner wall of the installation groove 8, and there are gaps between both ends of the heat conduction pad 61 and the two side inner walls of the installation groove 8 to form clamping grooves. The upper parts of both ends of the heat conduction plate 63 have protrusions adapted to the clamping grooves, and a groove adapted to the heat conduction pad 61 is formed between the two protrusions. Through the clamping of the protrusions and the clamping grooves and fixation with screws, the quick assembly of the heat conduction plate 63 and the base 1 is realized, ensuring the structural stability.

[0052] A plurality of second heat-conducting fins 64 are evenly distributed at equal intervals along the length direction of the heat-conducting plate 63. These second heat-conducting fins 64 are installed on the upper end surface of the heat-conducting plate 63, penetrate through the heat-conducting pad 61 and extend into the lower-layer channel, dividing the lower-layer channel into several single-wire harness channels. A heat-conducting gasket 62 is arranged at the bottom of each single-wire harness channel to support the wire harness.

[0053] As Figure 4 shown, the second heat-conducting fin 64 includes a first part 641, a second part 642, and a third part 643 arranged in sequence from top to bottom, and their widths increase in sequence.

[0054] The upper end of the first part 641 is inserted into and in thermal conduction with the lower end of the partition plate 4, realizing heat transfer between the upper and lower heat-dissipating components; the two sides of the second part 642 are concave arc surfaces and are in contact with the surface of the wire harness in the adjacent single-wire harness channel, increasing the contact area with the wire harness and improving the heat-conducting efficiency; the third part 643 is inserted and assembled with the base 1 and the heat-conducting pad 61, enhancing the stability of the second heat-conducting fin 64 and ensuring that it will not be displaced during the process of fixing the wire harness and conducting heat, and also contributing to the conduction of heat between various components.

[0055] In addition, through holes 9 adapted to the third part 643 are provided on both the heat-conducting pad 61 and the base 1. The through holes 9 are arranged between adjacent single-wire harness channels. The outer surface of the third part 643 is slidably inserted into the inner wall of the through hole 9, facilitating installation and disassembly. The second heat-radiating fin 65 is installed on the lower end surface of the heat-conducting plate 63 and extends downward, increasing the heat-radiating area and dissipating the heat conducted by the heat-conducting plate 63 into the surrounding environment, effectively reducing the temperature of the lower-layer wire harness.

[0056] As Figure 5 shown, a plurality of stable grooves 10 adapted to the wire harness are provided on both the upper and lower end surfaces of the partition plate 4. These stable grooves 10 are evenly distributed along the length direction of the partition plate 4, playing a role in limiting the wire harness and preventing the wire harness from moving horizontally in the upper and lower channels, further enhancing the fixing effect on the wire harness.

[0057] The partition plate 4 is also provided with insertion holes 11 located between adjacent two stable grooves 10. The lower heat-conducting part of the upper heat-dissipating component 5 and the upper heat-conducting part of the lower supporting heat-dissipating component 6 both extend into the insertion holes 11 and are in contact with each other, promoting the conduction of heat between the two components and realizing more efficient heat dissipation.

[0058] As Figure 1 、 Figure 3 and Figure 6As shown, in practical applications, in order to adapt to wire harnesses of different quantities and specifications, the lower end of the stopper 2 on the right side is slidably assembled with the upper right side of the base 1, facilitating the adjustment of the distance between the two stoppers 2. After the wire harness routing is completed, the free end of the connecting rod 7 installed on the right side stopper 2 is inserted into and fixed to the left side stopper 2 with bolts, thus completing the fastening work;

[0059] As Figure 1 shown, a cushion block 12 is installed at the bottom of one end of the base 1, and the other end has an extension plate 13. Both ends of the bent section of the extension plate 13 are connected to the base 1 and the horizontal section respectively. The bottom of the horizontal section is flush with the lower end of the cushion block 12, and the horizontal section is fixed to the installation surface with screws. The lower part of the base 1 is arched by the cushion block 12 and the extension plate 13 to form a lower-layer heat dissipation chamber, providing a better heat dissipation environment for the lower support heat dissipation component 6 and enhancing the heat dissipation effect.

[0060] In summary, through the collaborative work of various components, the wire harness fixing bracket of the present invention realizes the efficient fixing and heat dissipation of the wire harness, effectively solves the problems existing in the existing brackets, extends the service life of the wire harness, improves the stability of the wire harness connection, and the installation of each component is convenient, suitable for large-scale production and installation operations.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
