Description

Technical Field

[0001] The present application relates to the technical field related to wire harness protection, and in particular to a wire harness sleeve. Background Art

[0002] With the diversified development of new energy vehicles, the commonly used automotive wiring harnesses have also increased. As the pathway for electrical appliances, wiring harnesses transmit information and provide power like blood vessels. Therefore, in order to protect the smoothness and integrity of the entire line, the wiring harnesses need to be effectively protected.

[0003] At present, most of the existing automotive wiring harnesses use corrugated sleeves to protect the wiring harnesses. In order to facilitate the installation of the wiring harness, the corrugated sleeve is set along the axial opening. After the wiring harness is placed in the corrugated sleeve, the opening is generally closed by wrapping the corrugated sleeve with tape or tying the corrugated sleeve with a cable tie. However, the tape wrapping method is labor-intensive and tape-intensive, with high cost and poor heat dissipation; the method of tying the corrugated sleeve with cable ties at intervals is prone to openings in places where there is no cable tie, so that the exposed part of the wiring harness is prone to wear or scratches, and water and sand and stones are easy to enter the corrugated sleeve, resulting in line corrosion and sand and stone abrasion of the wiring harness, thereby causing circuit safety hazards. Utility Model Content

[0004] In view of this, it is necessary to provide a wiring harness sleeve that can solve the above technical problems.

[0005] In order to solve the above technical problems, this application provides the following technical solutions:

[0006] A wire harness sleeve, comprising a sleeve body, the sleeve body having a first free end and a second free end, the first free end being detachably connected to the second free end so that the sleeve body is closed and enclosed to form a receiving cavity, the receiving cavity being used to receive the wire harness;

[0007] The first free end is formed with a plurality of first bosses in sequence along the axial direction of the sleeve body, and the plurality of first bosses are connected to each other on the first free end. The second free end is formed with a plurality of second bosses in sequence along the axial direction of the sleeve body, and the plurality of first bosses correspond to the plurality of second bosses one by one, and the first bosses can be matched with the corresponding second bosses in a concave-convex manner to connect the first free end with the second free end.

[0008] It can be understood that when the sleeve body is applied to the wiring harness, the sleeve body can be opened and put on the wiring harness by utilizing the disconnection between the first free end and the second free end, and then the first free end and the second free end can be buckled together by utilizing the concave-convex fit between the multiple first bosses on the first free end and the multiple second bosses on the second free end, so that the wiring harness can be accommodated in the accommodating cavity formed by the closing and enclosing of the sleeve body. In this way, the sleeve body can be easily installed as a whole, preventing the wiring harness from being exposed outside the sleeve body, avoiding wear or abrasion of the wiring harness, and avoiding water corrosion and sand and stone wear on the wiring harness, thereby protecting the wiring harness; at the same time, the first bosses are connected to each other on the first free end, so that the first free end can form a whole connected to the second free end, so that the stability during connection can be improved and the overall force of the sleeve body can be better.

[0009] In one embodiment, the first boss has an abutment plane extending along the radial direction of the sleeve body, and the first boss can abut against the corresponding second boss through the abutment plane to limit the first boss from being disengaged from the corresponding second boss.

[0010] It can be understood that, by utilizing the abutment between the abutment plane on the first boss and the second boss, it is possible to limit the position of the first boss on the second boss and prevent the first boss from being detached from the second boss.

[0011] In one embodiment, the number of the abutment planes is two, and the two abutment planes are arranged at intervals along the axial direction of the sleeve body.

[0012] It can be understood that by utilizing the abutment between the two abutment planes on the first boss and the second boss, the stability of the connection between the first free end and the second free end can be improved.

[0013] In one embodiment, the width of the first boss gradually decreases toward the second free end;

[0014] And, the width of the second boss gradually decreases toward the first free end.

[0015] It is understandable that the structure in which the width of the first boss gradually decreases toward the second free end and the width of the second boss gradually decreases toward the first free end can facilitate the mutual engagement between the first boss and the second boss.

[0016] In one embodiment, the first free end partially protrudes outward along the radial direction of the sleeve body and forms the first boss;

[0017] And, the second free end partially protrudes outward along the radial direction of the sleeve body and forms the second boss.

[0018] It can be understood that, by using the first free end protruding outward to form a first boss and the second free end protruding outward to form a second boss, the sleeve body has a larger accommodating space when in use, so that the wiring harness sleeve can protect more wiring harnesses.

[0019] In one embodiment, the first boss is formed by extrusion of the first free end;

[0020] And, the second boss is formed by extrusion of the second free end.

[0021] It can be understood that the first boss is extruded from the first free end and the second boss is extruded from the second free end, so that the production and preparation of the sleeve body can be facilitated.

[0022] In one embodiment, the sleeve body is configured as a bellows structure.

[0023] In one embodiment, the sleeve body further comprises a sleeve body, and the first free end and the second free end are arranged on both sides of the sleeve body and are respectively connected to the sleeve body to form an integrated structure;

[0024] Among them, a plurality of bending protrusions are formed on the sleeve body, and the plurality of bending protrusions are arranged in sequence and at intervals along the circumferential direction of the sleeve body, and the plurality of bending protrusions are arranged in one-to-one correspondence with the plurality of first bosses and the plurality of second bosses.

[0025] It can be understood that the first free end, the second free end and the sleeve body are connected into an integral structure, so that the sleeve body can be prepared in one piece through a mold, thereby reducing the production cost; and along the circumferential direction of the sleeve body, a plurality of bending protrusions are formed on the sleeve body, so that the thickness of the sleeve body in the radial direction can be increased, thereby enhancing the structural strength of the sleeve body.

[0026] In one embodiment, a plurality of first extension protrusions are further formed on the first free end, the plurality of first extension protrusions correspond to the plurality of first bosses one by one, and the first extension protrusions are connected and communicated with the corresponding first bosses;

[0027] A plurality of second extending protrusions are also formed on the second free end, the plurality of second extending protrusions correspond to the plurality of second bosses one by one, and the second extending protrusions are connected and communicated with the corresponding second bosses;

[0028] Wherein, the second extending protrusion can be plug-fitted with the corresponding first extending protrusion.

[0029] It can be understood that the plug-in fit of the second extending protrusion with the corresponding first extending protrusion is helpful to improve the stability of the first boss and the second boss when they are mated and connected, and further prevent the first boss from being detached from the second boss.

[0030] In one embodiment, the sleeve body is made of nylon or polypropylene.

[0031] It is understandable that the material of the sleeve body is configured as nylon or polypropylene, so that the sleeve body can be integrally injection molded, thereby facilitating the production and preparation of the sleeve body.

[0044] The wire harness sleeve 100 for which protection is requested in the present application is not limited to use in new energy vehicles, but can also be used in wire harnesses that need protection in other places.

[0045] like Figures 1 to 3 As shown, a wiring harness sleeve 100 provided in an embodiment of the present application includes a sleeve body 10, the sleeve body 10 has a first free end 11 and a second free end 12, the first free end 11 can be detachably connected to the second free end 12, so that the sleeve body 10 is closed and enclosed to form a receiving cavity 101, and the receiving cavity 101 is used to accommodate the wiring harness 200; the first free end 11 is sequentially formed with a plurality of first bosses 111 along the axial direction of the sleeve body 10, and the plurality of first bosses 111 are connected to each other on the first free end 11, and the second free end 12 is sequentially formed with a plurality of second bosses 121 along the axial direction of the sleeve body 10, and the plurality of first bosses 111 correspond to the plurality of second bosses 121 one by one, and the first bosses 111 can be matched with the corresponding second bosses 121 in a concave-convex manner, so that the first free end 11 is connected to the second free end 12.

[0046] It can be understood that when the sleeve body 10 is applied to the wire harness 200, the sleeve body 10 can be opened and fitted onto the wire harness 200 by utilizing the disconnection between the first free end 11 and the second free end 12, and then the first free end 11 and the second free end 12 are buckled together by utilizing the concave-convex fit between the multiple first bosses 111 on the first free end 11 and the multiple second bosses 121 on the second free end 12, so that the wire harness 200 can be accommodated in the accommodating cavity 101 formed by closing and enclosing the sleeve body 10, so that , which can facilitate the overall installation of the sleeve body 10, prevent the wire harness from being exposed outside the sleeve body 10, avoid wear or abrasion of the wire harness 200, and avoid water corrosion and sand and stone wear of the wire harness 200, thereby protecting the wire harness 200; at the same time, the first boss 111 is connected to each other on the first free end 11, so that the first free end 11 can form a whole and be connected to the second free end 12, so that the stability during connection can be improved, and the overall force of the sleeve body 10 is better.

[0047] In one embodiment, the sleeve body 10 is made of nylon or polypropylene, that is, the sleeve body 10 can be integrally injection molded, thereby facilitating the production of the sleeve body 10 .

[0048] like Figure 2 , Figure 3 As shown, in one embodiment, the first free end 11 partially protrudes outward along the radial direction of the sleeve body 10 and forms a first boss 111; and the second free end 12 partially protrudes outward along the radial direction of the sleeve body 10 and forms a second boss 121. It can be understood that by protruding outward at the first free end 11 and forming the first boss 111 and the second free end 12 and forming the second boss 121, when the sleeve body 10 is in use, the sleeve body 10 has a larger accommodation space, so that the wire harness sleeve 100 can protect more wire harnesses 200.

[0049] like Figure 2 , Figure 3 As shown, in one embodiment, the first boss 111 is extruded from the first free end 11, and the second boss 121 is extruded from the second free end 12. In other words, the first boss 111 is extruded from the first free end 11 and the second boss 121 is extruded from the second free end 12, so that the production and preparation of the sleeve body 10 can be facilitated.

[0050] like Figure 2 , Figure 3 As shown, in one embodiment, the width of the first boss 111 gradually decreases toward the second free end 12; and the width of the second boss 121 gradually decreases toward the first free end 11. In this way, the first boss 111 and the second boss 121 are easily engaged with each other. Here, the width of the first boss 111 and the width of the second boss 121 refer to the width along the axial direction of the sleeve body 10.

In other words, by using the contact between the contact plane 1111 on the first boss 111 and the second boss 121, it is convenient to limit the first boss 111 on the second boss 121, so as to prevent the first boss 111 from being disengaged from the second boss 121.

[0052] In this embodiment, there are two abutment planes 1111, which are spaced apart along the axial direction of the sleeve body 10. That is, by abutting the two abutment planes 1111 on the first boss 111 with the second boss 121, the stability of the connection between the first free end 11 and the second free end 12 can be improved.

[0053] like Figure 2 , Figure 3 As shown, in one embodiment, a plurality of first extension protrusions 112 are formed on the first free end 11, and the plurality of first extension protrusions 112 correspond to the plurality of first bosses 111 one by one, and the first extension protrusions 112 are connected and communicated with the corresponding first bosses 111; a plurality of second extension protrusions 122 are formed on the second free end 12, and the plurality of second extension protrusions 122 correspond to the plurality of second bosses 121 one by one, and the second extension protrusions 122 are connected and communicated with the corresponding second bosses 121; wherein the second extension protrusions 122 can be plugged and matched with the corresponding first extension protrusions 112. In other words, by plugging and matching the second extension protrusions 122 with the corresponding first extension protrusions 112, it is beneficial to improve the stability of the first boss 111 and the second boss 121 when they are connected, and further prevent the first boss 111 from being detached from the second boss 121.

[0054] like Figures 1 to 3 As shown, in one embodiment, the sleeve body 10 is configured as a bellows structure.

[0055] like Figure 2 , Figure 3 As shown, in one embodiment, the sleeve body 10 further includes a sleeve body 13, and the first free end 11 and the second free end 12 are arranged on both sides of the sleeve body 13 and are respectively connected to the sleeve body 13 to form an integrated structure; wherein, a plurality of bending convex portions 131 are formed on the sleeve body 13, and the plurality of bending convex portions 131 are sequentially arranged at intervals along the circumferential direction of the sleeve body 10, and the plurality of bending convex portions 131 are arranged one by one corresponding to the plurality of first bosses 111 and the plurality of second bosses 121. That is to say, the first free end 11, the second free end 12 and the sleeve body 13 are connected to form an integrated structure, so that the sleeve body 10 can be prepared in one piece by a mold, thereby reducing the production cost; and along the circumferential direction of the sleeve body 10, a plurality of bending convex portions 131 are formed on the sleeve body 13, so that the thickness of the sleeve body 13 in the radial direction can be increased, thereby enhancing the structural strength of the sleeve body 10.

[0056] In summary, the wire harness sleeve 100 claimed for protection in the present application, when the sleeve body 10 is applied to the wire harness 200, the sleeve body 10 can be first opened and fitted onto the wire harness 200 by utilizing the disconnection between the first free end 11 and the second free end 12, and then the first free end 11 and the second free end 12 can be buckled together by utilizing the concave-convex fit between the multiple first bosses 111 on the first free end 11 and the multiple second bosses 121 on the second free end 12, so that the wire harness 200 can be accommodated in the accommodating cavity formed by closing and enclosing the sleeve body 10. 101, so that the sleeve body 10 can be easily installed as a whole, preventing the wiring harness from being exposed outside the sleeve body 10, avoiding the occurrence of wear or scratches on the wiring harness 200, and avoiding water corrosion on the wiring harness 200 and sand and stone wear on the wiring harness 200, thereby protecting the wiring harness 200; at the same time, the first boss 111 is connected to each other on the first free end 11, so that the first free end 11 can form a whole connected to the second free end 12, so that the stability during connection can be improved, and the overall force of the sleeve body 10 is better.

[0057] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.
