Description

Technical Field

[0001] This utility model belongs to the field of braided wire mesh production technology, specifically relating to a telescopic wire-wrapped flexible tube for automotive wiring harness protection. Background Technology

[0002] Braided wire harnesses are made of three strands of PET (polyethylene terephthalate) filaments, with a single filament diameter typically between 0.2 and 0.3 mm. They are formed into a mesh structure through precision mechanical weaving. They have good elasticity, flame retardancy, and wear resistance, and are often used for wire harness protection in electronic equipment, the automotive industry, and the aerospace field.

[0003] Currently, braided mesh tubes are generally directly braided into a tubular structure, which is then fitted around the wire harness to form protection for the wire harness. However, due to their non-removable nature, this type of tubular mesh tube causes inconvenience for the later maintenance of the wire harness.

[0004] There are now improvements on the market to address the non-removable nature of this tubular structure. For example, Velcro can be used to form a ring-like bond between the two sides of the woven mesh. However, with long-term use, the Velcro's adhesiveness will decrease, and when wrapping multi-strand or thicker wire harnesses, the bond is not strong and is easily loosened by external forces, such as engine vibration.

[0005] In view of this, the present invention provides a retractable wire harness for automotive wiring harness protection, which achieves the detachability of the braided mesh while ensuring its secure coverage. Utility Model Content

[0006] To achieve the above objectives, the present invention provides the following technical solution: a retractable wire harness for automotive wiring harness protection, comprising a braided mesh (1), a first connector (2) connected to one side of the braided mesh (1), and a second connector (3) connected to the other side of the braided mesh (1) relative to the first connector (2);

[0007] The first connector (2) has a notch (22) on the side away from the woven mesh (1), and the second connector (3) has a protrusion (32) on the side away from the woven mesh (1) that matches the notch (22);

[0008] The surface of the first connector (2) is provided with a through threaded hole (4) perpendicular to the length direction of the recess (22), and the surface of the protrusion (32) is provided with a through hole (5) corresponding to the threaded hole (4) perpendicular to the length direction of the protrusion (32).

[0009] After the protrusion (32) is inserted and connected to the notch (22), the threaded hole (4) and the through hole (5) are axially connected by fasteners so that the braided mesh (1) forms a tubular wrapped wire bundle.

[0010] As a preferred embodiment of the retractable flexible wire harness for automotive wiring harness protection according to this utility model, the first connector (2) has a first connection port (21) on the other side of the notch (22) for connecting with the braided mesh (1).

[0011] As a preferred embodiment of the retractable flexible wire harness for automotive wiring harness protection according to this utility model, the second connector (3) has a second connection port (31) on the other side of the protrusion (32) for connecting with the braided mesh (1).

[0012] As a preferred embodiment of the retractable wire harness for automotive wiring harness protection according to this utility model, the inner side of one end of the braided mesh (1) is provided with a first adhesive member (6), and the outer side of the other end of the braided mesh (1) is provided with a second adhesive member (7) that can be adhered to the first adhesive member (6).

[0013] As a preferred embodiment of the telescopic flexible wire harness for automotive wiring harness protection according to this utility model, the first adhesive member (6) is a magic female adhesive and the second adhesive member (7) is a magic female adhesive.

[0014] As a preferred embodiment of the retractable wire harness hose for automotive wiring harness protection according to this utility model, the braided mesh (1) is made of PET material.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model achieves a firm connection between the first connector (2) and the second connector (3) through the insertion between the notch (22) and the protrusion (32) and the axial connection between the threaded hole (4) and the through hole (5) by fasteners, while also being detachable, thereby effectively ensuring the firmness of the wire harness wrapping.

[0017] This utility model utilizes the adhesiveness between the first adhesive member (6) and the second adhesive member (7) to facilitate the connection between the formed tubular braided mesh (1) and also to provide segmented protection for longer wire harnesses. When it is necessary to inspect a certain section of the wire harness, it is only necessary to remove the braided mesh covering that section of the wire harness, which facilitates subsequent inspection and maintenance operations.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model relates to a retractable flexible wire harness for protecting automotive wiring harnesses, such as... Figures 1-2 As shown, it includes a woven mesh 1, a first connector 2 connected to one side of the woven mesh 1, and a second connector 3 connected to the other side of the woven mesh 1 relative to the first connector 2. The first connector 2 and the second connector 3 are detachably connected by fasteners.

[0027] Specifically, the first connector 2 has a notch 22 extending along the length of the first connector 2 on the side away from the braided mesh 1. The notch 22 divides the first connector 2 into a first sidewall 23 and a second sidewall 24. The second connector 3 has a protrusion 32 that matches the notch 22 on the side away from the braided mesh 1. When the second connector 3 is pulled so that the protrusion 32 on the second connector 3 is inserted into the notch 22 on the first connector 2, the braided mesh 1 can form a tubular structure to facilitate the wrapping of the wire harness 8.

[0028] Furthermore, the first connector 2 has a first connection port 21 for connecting with the woven mesh 1 on the other side of the recess 22; the second connector 3 has a second connection port 31 for connecting with the woven mesh 1 on the other side of the protrusion 32. By inserting both sides of the woven mesh 1 into the first connection port 21 and the second connection port 31 respectively, and then bonding them with glue, the connection between the woven mesh 1 and the first connector 2 and the second connector 3 can be realized.

[0029] Furthermore, in order to achieve a firm connection between the recess 22 and the protrusion 32, as well as detachability, a through threaded hole 4 is provided on the surface of the first connector 2 and perpendicular to the length direction of the recess 22. The threaded hole 4 is located on the first side wall 23 and its end is connected to the recess 22. When it is threadedly connected with a fastener bolt, the end of the fastener can be inserted into the recess 22. A through hole 5 corresponding to the threaded hole 4 is provided on the surface of the protrusion 32 perpendicular to the length direction of the protrusion 32.

[0030] After the protrusion 32 is inserted into the recess 22, the end of the fastener can be inserted into the through hole 5 on the surface of the protrusion 32 by using the threaded connection of the fastener to the threaded hole 4, thereby locking and fixing the protrusion 32. In addition, disassembly can be performed simply by unscrewing the fastener.

[0031] It should be noted that in this embodiment, three sets of threaded holes 4 are evenly spaced, located at both ends and the middle of the first connector 2, respectively, to ensure the uniformity of force distribution after the protrusion 32 and the recess 22 are connected. In particular, the number of threaded holes 4 can also be adapted to the actual length of the woven mesh 1.

[0032] Figures 3-5 The second embodiment of the present invention is shown, which differs from the above embodiment in that: a first adhesive member 6 is provided on the inner side of one end of the woven mesh 1, and a second adhesive member 7 is provided on the outer side of the other end of the woven mesh 1, which can be adhered to the first adhesive member 6, so as to achieve a tight multi-segment connection between the woven meshes 1.

[0033] Preferably, in this embodiment, the first adhesive 6 is a magic thread adhesive and the second adhesive 7 is a magic thread adhesive.

[0034] In use, the first section of braided mesh 1 is wrapped around the outside of the wire harness 8. During this process, the second adhesive 7 located on the outside of the braided mesh 1 will form a ring structure on the outside of the braided mesh 1. Then, the second section of braided mesh 1 is wrapped around the outside of the wire harness 8. During this process, the first adhesive 6 located on the inside of the second section of braided mesh 1, which forms a ring structure, needs to wrap and adhere the first section of the second adhesive 7 located on the outside of the braided mesh 1. In the same way, multiple sections of braided mesh 1 are connected sequentially according to the length of the wire harness 8 to form a multi-segment wrapping of a longer wire harness 8. When a certain section of the wire harness 8 needs to be repaired, it is only necessary to remove the braided mesh 1 wrapped around that section of the wire harness 8.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
