[0030] The embodiments of the present utility model will be described in detail below. The embodiments described with reference to the drawings are exemplary. Below, reference is made to Figures 1 - 5 Describe a protective sleeve 100 for a wire harness 50 according to an embodiment of the present utility model. The protective sleeve 100 for the wire harness 50 includes: a first connecting member 10 and a second connecting member 20.

[0031] Specifically, as Figure 1 and Figure 2 shown, a mating groove 21 is provided on one of the first connecting member 10 and the second connecting member 20, and a mating portion 11 is provided on the other of the first connecting member 10 and the second connecting member 20. The mating groove 21 and the mating portion 11 are detachably engaged along the axial direction of the protective sleeve 100.

[0032] In this embodiment, the protective sleeve 100 for the wire harness 50 includes a first connecting member 10 and a second connecting member 20 arranged along the length direction of the protective sleeve 100. The first connecting member 10 and the second connecting member 20 form the protective sleeve 100 for protecting the wire harness 50. One end of the first connecting member 10 and one end of the second connecting member 20 are arranged adjacent to each other along the length direction of the protective sleeve 100, and the other end of the first connecting member 10 and the other end of the second connecting member 20 extend away from each other along the length direction of the protective sleeve 100 respectively. The mating groove 21 is provided on one of the first connecting member 10 and the second connecting member, and the mating portion 11 is provided on the other of the first connecting member 10 and the second connecting member 20. Moreover, the mating groove 21 and the mating portion 11 are respectively provided at the adjacent ends of the first connecting member 10 and the second connecting member 20. The mating groove 21 and the mating portion 11 can be directly connected and mated along the length direction of the protective sleeve 100 and towards each other, or separated in the direction away from each other. For example, the mating portion 11 is axially arranged at the said one end of the first connecting member 10 along the protective sleeve 100, and the mating groove 21 is axially arranged at the said one end of the second connecting member 20 along the protective sleeve 100.

[0033] For the protective sleeve 100 for the wire harness 50 according to the embodiment of the present invention, by making the mating groove 21 and the mating portion 11 detachably engage along the length direction of the protective sleeve 100, the first connecting member 10 and the second connecting member 20 are detachably assembled, which simplifies the installation steps of the protective sleeve 100, improves the installation efficiency of the protective sleeve 100, effectively protects the wire harness 50 inside the first connecting member 10 and the second connecting member 20, and plays a role in fixing the wire harness 50.

[0034] According to some embodiments of the present invention, as Figure 2 shown, the mating portion 11 includes: a first mating portion 111 and a second mating portion 112. One end of the first mating portion 111 is connected to the first connecting member 10; one end of the second mating portion 112 is connected to the other end of the first mating portion 111, and the other end of the second mating portion 112 extends axially towards the first connecting member 10 along the protective sleeve 100 and is inclined in the direction away from the center line of the protective sleeve 100.

[0035] That is, the first engaging portion 111 extends along the length direction of the protective sleeve 100. One end of the first engaging portion 111 is connected to one end of the first connecting member 10 adjacent to the second connecting member 20. The other end of the first engaging portion 111 away from the first connecting member 10 is connected to the second engaging portion 112. The other end of the second engaging portion 112 extends obliquely in the direction of the center line of the protective sleeve 100, that is, in the axial direction of the protective sleeve 100 from the second connecting member 20 to the first connecting member 10 and gradually away from the first engaging portion 111. In this embodiment, along the axial direction of the protective sleeve 100 from the second connecting member 20 to the first connecting member 10, the cross-sectional area of the engaging portion 11 gradually increases. Thus, one end of the first engaging portion 111 is connected to the first connecting member 10, one end of the second engaging portion 112 is connected to the other end of the first engaging portion 111, and the first engaging portion 111 and the second engaging portion 112 together form the engaging portion 11. The obliquely arranged second engaging portion 112 provides a guiding function for the engagement between the engaging portion 11 and the engaging groove 21, facilitating the connection between the first connecting member 10 and the second connecting member 20, increasing the tightness of the connection between the engaging portion 11 and the engaging groove 21, and preventing the engaging portion 11 from disengaging from the engaging groove 21.

[0036] According to some embodiments of the present invention, at least one of the first engaging portion 111 and the second engaging portion 112 is an elastic member.

[0037] That is, the first engaging portion 111 is an elastic member, or the second engaging portion 112 is an elastic member, or both the first engaging portion 111 and the second engaging portion 112 are elastic members. In this embodiment, both the first engaging portion 111 and the second engaging portion 112 are elastic members. The elastic member is made of PVC material. PVC is also known as Polyvinyl chloride and is widely used. There are two types of PVC, rigid and soft. In this embodiment, the second engaging portion 112 is made of soft PVC. Soft PVC has the characteristics of high toughness, wear resistance, corrosion resistance, strong tear resistance, strong weldability, antistatic property, and easy processing.

[0038] Thus, at least one of the first engaging portion 111 and the second engaging portion 112 being an elastic member can facilitate the connection and disconnection between the engaging portion 11 formed by the first engaging portion 111 and the second engaging portion 112 and the engaging groove 21 on the second connecting member 20, prevent the second engaging portion 112 from breaking due to too low structural strength, prevent the second engaging portion 112 from being worn after the protective sleeve 100 is used multiple times, extend the service life of the protective sleeve 100, and the second engaging portion 112 is easy to process, which can reduce the processing precision of the engaging portion 11 and the engaging groove 21, thereby improving the production efficiency of the protective sleeve 100. At the same time, it can block the release of static electricity generated by the wire harness 50 inside the protective sleeve 100 and improve safety.

[0039] According to some embodiments of the present invention, such asFigure 4 As shown, a limiting member 211 is provided in the fitting groove 21. The limiting member 211 is arranged on one side of the fitting groove 21 along the radial direction of the protective sleeve 100 away from the center of the protective sleeve 100, and the fitting portion 11 and the limiting member 211 are detachably fitted.

[0040] The limiting member 211 extends along the length direction of the protective sleeve 100 and is arranged on the side wall of the fitting groove 21 away from the center of the protective sleeve 100. When the second fitting portion 112 is inserted into the fitting groove 21, the size of the second fitting portion 112 is larger than that of the fitting groove 21. Therefore, the second fitting portion 112 and the fitting groove 21 are mutually extruded, and the extrusion force pushes the front end of the second fitting portion 112 to contract into the fitting groove 21, so that after the first fitting portion 111 and the second fitting portion 112 jointly enter the fitting groove 21, the second fitting portion 112 deforms along the radial direction of the protective sleeve 100 toward the direction away from the first fitting portion 111 and abuts against the limiting member 211, which can effectively prevent the fitting portion 11 from disengaging from the fitting groove 21.

[0041] Thus, a limiting member 211 is provided in the fitting groove 21. After the fitting portion 11 is inserted into the fitting groove 21, the limiting member 211 and the second fitting portion 112 interact with each other. The limiting member 211 can limit the second fitting portion 112 to prevent the second fitting portion 112 from continuing to move or falling off from the fitting groove 21, thereby making the connection between the first connecting member 10 and the second connecting member 20 more firm and improving the reliability of the protective sleeve 100.

[0042] According to some embodiments of the present invention, as Figure 3 and Figure 4 shown, the second connecting member 20 is formed with a communication hole. The communication hole is arranged on the outer peripheral wall of the second connecting member 20 and is communicated with the fitting groove 21; the protective sleeve 100 for the wire harness 50 further includes: a pressing assembly 30. The pressing assembly 30 is movably arranged at the communication hole, and the pressing assembly 30 contacts the fitting portion 11 to separate the first connecting member 10 and the second connecting member 20.

[0043] That is, the communication hole is arranged on the second connecting member 20 and is communicated with the fitting groove 21 along the radial direction of the protective sleeve 100. When the fitting portion 11 is fitted with the fitting groove 21, the second fitting portion 112 included in the fitting portion 11 is opposite to the communication hole. The pressing assembly 30 is fitted at the communication hole and moves along the radial direction of the protective sleeve 100. For example, when the pressing assembly 30 is acted on by an external force and moves along the radial direction of the protective sleeve 100 toward the second fitting portion 112, the second fitting portion 112 is extruded, and the fitting portion 11 can be adapted to disengage from the fitting groove 21 to realize the separation of the first connecting member 10 and the second connecting member 20. When the pressing assembly 30 is not acted on by an external force, the fitting portion 11 is fitted with the fitting groove 21, and the fitting portion 11 extrudes the pressing assembly 30 to abut against the limiting member 211 to complete the fitting of the first connecting member 10 and the second connecting member 20.

[0044] Thus, when the protective cover 100 needs to be disassembled, the pressing assembly 30 can squeeze the second engaging portion 112 in the engaging groove 21, causing the second engaging portion 112 to contract and separate from the limiting member 211. Thereby, the first connecting member 10 can be pulled outwards, that is, the first connecting member 10 and the second connecting member 20 are separated along the length direction of the protective cover 100. The disassembly of the protective cover 100 can be completed without the aid of external tools, and the disassembly process is simple, effectively improving the working efficiency of the protective cover 100.

[0045] According to some embodiments of the present invention, such as Figure 4 As shown, the pressing assembly 30 includes: a pressing link 31 and a limiting ring 32. One end of the pressing link 31 is located in the engaging groove 21; the limiting ring 32 is provided at one end of the pressing link 31, and the limiting ring 32 cooperates with the pressing link 31.

[0046] That is, the limiting ring 32 is provided in the engaging groove 21 and is located on the side wall of the engaging groove 21 along the radial direction of the protective cover 100 away from the center of the protective cover 100. The limiting ring 32 and the end of the pressing link 31 located in the engaging groove 21 form a fixed fit. The other end of the pressing link 31, that is, the other end away from the engaging portion 11, extends along the radial direction of the protective cover 100 and towards the direction away from the protective cover 100 to the outside of the protective cover 100. Thus, one end of the pressing link 31 is located in the engaging groove 21, which facilitates the pressing link 31 to squeeze the second engaging portion 112 when the protective cover 100 needs to be disassembled; the cooperation between the limiting ring 32 and the pressing link 31 can limit the pressing link 31 along the length direction of the protective cover 100, preventing the pressing link 31 from falling off from the limiting groove, and improving the firmness and reliability of the connection between the pressing assembly 30 and the engaging groove 21.

[0047] According to some embodiments of the present invention, such as Figure 2 As shown, there are multiple engaging portions 11, and the multiple engaging portions 11 are arranged at intervals along the circumferential direction of the protective cover 100; there are multiple engaging grooves 21, and the multiple engaging grooves 21 are arranged at intervals along the circumferential direction of the protective cover 100, and the multiple engaging grooves 21 respectively correspond to the multiple engaging portions 11.

[0048] In this embodiment, there are multiple engaging grooves 21 and multiple engaging portions 11. The multiple engaging grooves 21 are arranged at intervals along the circumferential direction of the second connecting member 20, the multiple engaging portions 11 are arranged at intervals along the circumferential direction of the first connecting member 10, the multiple engaging portions 11 and the multiple engaging grooves 21 correspond to each other one by one along the axial direction of the protective cover 100, and are respectively detachably engaged.

[0049] Therefore, there are multiple first engaging portions 111, multiple second engaging portions 112, and multiple engaging grooves 21. The multiple engaging grooves 21 respectively correspond to the multiple engaging portions 11. When the first connector 10 is connected to the second connector 20, the stress received at the connection between the first connector 10 and the second connector 20 can be dispersed, avoiding stress concentration, and improving the structural strength of the first connector 10 and the second connector 20. At the same time, it is convenient for the multiple engaging portions 11 to deform simultaneously, and it is convenient for the engaging portions 11 to be disengaged from the engaging grooves 21 under the action of an external force.

[0050] According to some embodiments of the present invention, as Figure 1 and Figure 5 shown, the protective sleeve 100 for the wire harness 50 further includes: a cutting device 40. The cutting device 40 is sleeved on the outer peripheral side of the protective sleeve 100. The cutting device 40 includes: a mounting bracket 41 and a cutting assembly 42; the cutting assembly 42 is disposed on the mounting bracket 41, and the cutting assembly 42 is movable along the radial direction of the protective sleeve 100 to cut the protective sleeve 100.

[0051] That is, the mounting bracket 41 is sleeved on the outer peripheral side of the protective sleeve 100 and is connected to the protective sleeve 100. One end of the cutting assembly 42 is connected to the mounting bracket 41, and the other end of the cutting assembly 42 is disposed between the mounting bracket 41 and the protective sleeve 100, and is movable relative to the protective sleeve 100 along the radial direction of the protective sleeve 100 to cut the protective sleeve 100.

[0052] Therefore, the cutting assembly 42 is disposed on the mounting bracket 41, and the cutting assembly 42 can be fixed by the mounting bracket 41, saving the occupied space of the cutting device 40 and improving the space utilization rate of the protective sleeve 100; when the protective sleeve 100 is damaged, the damaged protective sleeve 100 can be cut off by moving the cutting assembly 42 along the radial direction of the protective sleeve 100, which can simplify the steps of dealing with the damaged protective sleeve 100, improve the working efficiency of the cutting device 40, and improve the practicability of the protective sleeve 100.

[0053] According to some embodiments of the present invention, as Figure 5 shown, the cutting assembly 42 includes: a moving rod 421 and a cutting member 422. The moving rod 421 is movably disposed on the mounting bracket 41 along the radial direction of the protective sleeve 100; the moving rod 421 passes through the mounting bracket 41 and is connected to the cutting member 422.

[0054] That is, the moving rod 421 is arranged along the radial direction of the protective sleeve 100 and is movable relative to the mounting bracket 41. One end of the moving rod 421 extends outward from the mounting bracket 41 away from the protective sleeve 100, and the other end penetrates through the mounting bracket 41 and is provided with a cutting member 422. The cutting member 422 is arranged at an interval from the protective sleeve 100 along the radial direction of the protective sleeve 100. The cutting member 422 is connected to the moving rod 421. When it is necessary to cut a part of the protective sleeve 100, the force acting on the moving rod 421 can drive the cutting member 422 to cut the protective sleeve 100. Thus, the moving rod 421 is movably arranged on the mounting bracket 41 along the radial direction of the protective sleeve 100, and the moving rod 421 passes through the mounting bracket 41 and is connected to the cutting member 422, which is convenient for fixing the cutting member 422 and for the cutting member 422 to cut and repair the damaged protective sleeve 100.

[0055] According to some embodiments of the present invention, as Figure 5 shown, the cutting assembly 42 further includes: an elastic connecting member 423, the elastic connecting member 423 is arranged between the cutting member 422 and the mounting bracket 41, one end of the elastic connecting member 423 is connected to the cutting member 422, and the other end of the elastic connecting member 423 is connected to the mounting bracket 41.

[0056] In this embodiment, there are multiple elastic connecting members 423. Two elastic connecting members 423 are provided on each cutting member 422 and the moving rod 421. The elastic connecting members 423 are arranged at intervals on the cutting member 422 along the circumferential direction of the protective sleeve 100, and are arranged along the radial direction of the protective sleeve 100 between the cutting member 422 and the mounting bracket 41. The two ends of the elastic connecting member 423 are respectively elastically connected to the mounting bracket 41 and the cutting member 422.

[0057] Thus, one end of the elastic connecting member 423 is connected to the cutting member 422, and the other end of the elastic connecting member 423 is connected to the mounting bracket 41, which is convenient for the relative movement of the cutting member 422 along the radial direction of the protective sleeve 100 with respect to the mounting bracket 41 and for limiting the cutting member 422, restricting the thickness of the protective sleeve 100 cut by the cutting member 422, and preventing the cutting member 422 from damaging the wire harness 50 inside the protective sleeve 100. When it is necessary to cut the protective sleeve 100, an external force acts on the moving rod 421 to drive the cutting member 422 to overcome the action of the elastic connecting member 423 to form a cut on the protective sleeve 100; when the external force is removed, the elastic connecting member 423 drives the cutting member 422 to reset, so that the cutting member 422 quickly returns to its original position and buffers the acting force between the cutting member 422 and the mounting bracket 41, avoiding damage to the mounting bracket 41 or the cutting member 422.

[0058] According to some embodiments of the present invention, as Figure 5As shown, the mounting bracket 41 includes: a first bracket 411 and a second bracket 412; the second bracket 412 is provided on the radially inner side of the first bracket 411 along the protective sleeve 100, the cutting member 422 is provided between the first bracket 411 and the second bracket 412, a through hole is formed on the second bracket 412, and the cutting member 422 is movable radially along the protective sleeve 100 at the through hole.

[0059] That is, the first bracket 411 and the second bracket 412 are arranged at intervals along the radial direction of the protective sleeve 100. The second bracket 412 is provided between the first bracket 411 and the protective sleeve 100, and the second bracket 412 is sleeved on the outer peripheral side of the protective sleeve 100. A through hole is formed on the second bracket 412 along the circumferential direction of the protective sleeve 100, and the cutting member 422 can be moved relative to the protective sleeve 100 radially at the through hole. In this embodiment, there may be multiple cutting members 422, and the multiple cutting members 422 are arranged at intervals along the circumferential direction of the protective sleeve 100. An installation space is formed between the first bracket 411 and the second bracket 412 for the installation and movement of the cutting member 422. When it is necessary to cut the protective sleeve 100, the cutting member 422 moves radially towards the second bracket 412 along the protective sleeve 100, and passes through the through hole provided on the second bracket 412 to contact the protective sleeve 100 to realize the cutting of the protective sleeve 100.

[0060] Thus, the second bracket 412 is provided on the radially inner side of the first bracket 411 along the protective sleeve 100, which facilitates the movement and rotation of the mounting bracket 41 on the protective sleeve 100, facilitates quickly moving the cutting device 40 to the damaged part of the protective sleeve 100, and improves the working efficiency of the cutting device 40; a through hole is formed on the second bracket 412, which provides a guiding function when the cutting member 422 cuts the protective sleeve 100. The cutting member 422 is movable radially along the protective sleeve 100 at the through hole. By pressing and rotating the moving rod 421, the cutting member 422 can pass through the through hole and cut the damaged protective sleeve 100 along the circumferential direction of the protective sleeve 100.

[0061] According to some embodiments of the present invention, as Figure 5 shown, the protective sleeve 100 for the wire harness 50 further includes: a third bracket 413, the third bracket 413 is provided between the first bracket 411 and the second bracket 412, and both ends of the third bracket 413 are respectively connected to the first bracket 411 and the second bracket 412.

[0062] In this embodiment, there are multiple third brackets 413. The multiple third brackets 413 are divided into two groups. The two groups of third brackets 413 are arranged at intervals along the length direction of the protective sleeve 100. One end of the third bracket 413 is connected to the first bracket 411, and the other end is connected to the second bracket 412. Moreover, the multiple third brackets 413 are respectively arranged circumferentially along the protective sleeve 100 between two adjacent cutting members 422. That is to say, there are two second brackets 412. The two second brackets 412 are arranged at intervals along the axial direction of the protective sleeve 100 to define a through hole. The two groups of third brackets 413 are respectively arranged between the two second brackets 412 and the first bracket 411.

[0063] Thus, the multiple third brackets 413 are arranged between the first bracket 411 and the second bracket 412, which is convenient for connecting the first bracket 411 and the second bracket 412.
