Description

Technical Field

[0001] This utility model relates to the field of wiring connection technology, specifically to a quick-detachable automotive wiring harness assembly. Background Technology

[0002] Automotive wiring harnesses are the core connection units of automotive circuits, equivalent to the "neural network" of a car. By integrating wires, connectors, protective components, and fasteners, they enable current transmission and signal interaction between various electronic systems of the car (such as the engine, chassis, body, smart cockpit, and autonomous driving system), ensuring the stable operation of the vehicle's electrical functions.

[0003] Traditional wire harnesses use tape to wrap the wires in and out, and then insert the wrapped wires into a corrugated tube. This type of wire harness structure is very troublesome when maintaining or disassembling a single line. It requires removing all the lines before it can be removed from the corrugated tube, or the corrugated tube must be broken to maintain or replace the lines. However, after maintenance, the corrugated tube can no longer provide a seal, and the tape that penetrates the tube cannot be used after removal. This increases the cost of disassembling the wire harness assembly and makes wire harness maintenance inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a quick-detachable automotive wiring harness assembly. A strip of plastic wraps around the connecting wire assembly, automatically adjusting to the size of the wiring harness. The plastic wrap is connected to a thickened base via caps on both sides using a connecting assembly. This not only provides a seal but also allows for quick removal from the outside of the connecting wire assembly during disassembly. Furthermore, the plastic wrap is reusable, facilitating disassembly and maintenance of the automotive wiring harness and addressing the problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick-detachable automotive wiring harness assembly, comprising:

[0006] Multi-strand connector assembly and a sealed protective structure for wrapping the connector assembly;

[0007] The sealing and protective structure includes a strip of plastic that is wrapped around the outside of the connecting wire assembly. A cap plate extends outward from one side of the plastic that is wrapped around the outside of the connecting wire assembly. A thickened seat is provided on the other side of the plastic that is wrapped around the cap plate. A connecting assembly is provided between the cap plate and the thickened seat.

[0008] Preferably, the connecting assembly includes two sets of slots on the outer side of the thickened seat, and a locking strip is provided on the inner side of the cap plate, the locking strip being engaged in the slots.

[0009] Preferably, the outer side of the plastic part is further recessed inward with multiple sets of grooves, and the inner wall of the grooves is provided with multiple sets of crack-prone lines.

[0010] Preferably, the connecting wire assembly includes a variety of enameled wires, and connectors are connected to both ends of the enameled wires.

[0011] Preferably, the connector includes a plug and a socket, wherein the interior of the plug and the socket are crimped to the wires inside the enameled wire via conductive terminals.

[0012] Preferably, each set of card slots has two sets of card strips engaged, the card strips including a raised curved surface and a smooth flat surface, the curved surface being in contact with the inner wall of the card slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model uses a strip of plastic material wrapped around the outside of the connecting wire assembly. Then, the cap plate and the thickened seat are connected by the connecting assembly to complete the splicing of both sides of the plastic material, so that the plastic material is assembled into a tubular structure, which facilitates the binding of the connecting wire assembly. At the same time, the plastic material is elastic and can be adjusted according to the size of the wire harness, avoiding the difficulty of inserting the wire harness into the traditional corrugated tube. In addition, the plastic material can be reused after being spirally removed, avoiding the inability to continue using the traditional corrugated tube after it breaks. This not only reduces the cost of wire harness maintenance, but also facilitates the maintenance of the wire harness.

[0015] 2. This utility model has a groove on the outside of the plastic part, which makes it convenient to pass through the plastic part in the groove, to split the wire harness, and to facilitate sealing. Attached Figure Description

[0022] 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.

[0023] This utility model provides, for example Figures 1-5 The illustrated quick-detachable automotive wiring harness assembly includes:

[0024] Multi-strand connecting wire assembly 1 and a sealed protective structure 2 that wraps the connecting wire assembly 1;

[0025] The sealing and protective structure 2 includes a strip-shaped plastic part 3, which is wrapped around the outside of the connecting wire assembly 1. A cap plate 4 extends outward from one side of the plastic part 3, and a thickened seat 5 is provided on the other side of the plastic part 3. A connecting assembly 6 is provided between the cap plate 4 and the thickened seat 5.

[0026] Plastic part 3 is made of thermotropic shape memory plastic, such as shape memory polyurethane (SMPU), shape memory polyethylene (SMPE), and shape memory epoxy resin. The processing method is as follows: The shape memory plastic sheet is heated to its specific "transition temperature" (such as about 60-120℃ for SMPU, depending on the material). At this time, the activity of the plastic molecular chain increases and enters the "high elasticity state". While maintaining the heating state, the plastic sheet is fixed in the target "memory shape" (such as the flat shape you want it to eventually return to, or a specific curvature), and then slowly cooled to room temperature in this state. After cooling, the plastic molecular chain structure is fixed and the "memory shape" is permanently recorded.

[0027] The strip-shaped plastic part 3 is wrapped around the outside of the connecting wire assembly 1. Then, the cap plate 4 and the thickened seat 5 are connected by the connecting component 6 to complete the splicing of both sides of the plastic part 3, so that the plastic part 3 is assembled into a tubular structure, which makes it easy to bind the connecting wire assembly 1. At the same time, the plastic part 3 is elastic and can be adjusted according to the size of the wire harness, avoiding the difficulty of inserting the wire harness into the traditional corrugated tube. In addition, the plastic part 3 can be reused after being spirally removed, avoiding the inability to continue using the traditional corrugated tube after it breaks. This not only reduces the cost of wire harness maintenance, but also facilitates the maintenance of the wire harness.

[0028] Among them, such as Figure 2 As shown:

[0029] The connecting component 6 includes two sets of slots 61 on the outer side of the thickened base 5, and a clip 62 on the inner side of the cap plate 4. The clip 62 is engaged in the slots 61. Through the cooperation of the clip 62 and the slots 61, the cap plate 4 and the thickened base 5 can be easily attached to complete the splicing of the two sides of the plastic part 3, so that the plastic part 3 forms a tubular structure to wrap the wire harness. This not only binds the wire harness, but also isolates moisture and prevents the wire harness from being in a humid environment.

[0030] Furthermore, such as Figure 4 As shown:

[0031] The outer side of the plastic part 3 is also recessed inward with multiple sets of grooves 7. Multiple sets of easily cracked lines are provided on the inner wall of the grooves 7. By providing grooves 7 on the outer side of the plastic part 3, it is convenient to pass through the plastic part 3 at the grooves 7 to divert the wire bundle, and it is also convenient to perform sealing treatment. At the easily cracked lines, it is easy to tear to form a through opening.

[0032] Preferred, such as Figure 3 As shown:

[0033] The connecting wire assembly 1 includes various enameled wires 101, with connectors 102 connected to both ends of the enameled wires 101. By installing connectors 102 at both ends of the enameled wires 101, it is convenient to quickly assemble and disassemble the enameled wires 101, complete the disassembly and assembly of partial wiring harnesses, avoid disassembling the entire vehicle wiring, and make maintenance and disassembly more convenient.

[0034] It is worth noting that, such as Figure 3 As shown:

[0035] The connector 102 includes a plug and a socket. The plug and socket are crimped with the wires inside the enameled wire 101 through conductive terminals. By setting the structure of the connector 102, it is convenient to select the appropriate plug and socket according to the function of different connecting wires and connect them to the corresponding devices.

[0036] In a further preferred embodiment, such as Figure 5 As shown:

[0037] Each set of slots 61 contains two sets of clips 62. Each clip 62 includes a raised curved surface 621 and a smooth flat surface 622. The curved surface 621 fits against the inner wall of the slot 61. By defining the structure of the clip 62, the curved surface 621 fits against the inner wall of the slot 61, ensuring the stability of the connection and providing a sealing and isolation function to ensure that the connecting wire is in a dry environment.

[0038] In practical use, the plug and socket are installed at both ends of the enameled wire 101. Multiple sets of enameled wire 101 are then gathered together. The plastic part 3 is then wrapped around the outside of the enameled wire 101 bundle, and the cap plate 4 is secured to the outside of the thickened base 5. Simultaneously, the retaining strip 62 is pressed into the retaining groove 61, ensuring the retaining strip 62 engages within the groove 61. This allows the cap plate 4 to fit snugly against the thickened base 5. The plastic part 3 is then wrapped around the outside of the bundle in sequence to form a tubular structure, thus wrapping and binding the bundle. When one set of bundles needs to be inserted... When reversing the direction of the wire harness, puncture the easily cracked wire in the groove 7 nearby to open the groove 7. Then, pass the wire harness that needs to be reversed through the groove 7 and wrap it with a separate plastic part 3. When the wire harness needs to be disassembled, simply remove the connectors 102 at both ends of the enameled wire 101 quickly, then rotate the plastic part 3 in the opposite direction on the outside of the wire harness to contact the wire harness restraint, and replace the enameled wire 101 that needs maintenance. After completion, wrap the plastic part 3 back around the outside of the wire harness.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
