Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-voltage wire harness technology, and in particular to a high-voltage wire harness with an interlocking wire assembly sheath. Background Technology
[0002] In fields such as new energy vehicles and industrial equipment, high-voltage wiring harnesses are core components for realizing power transmission and signal interaction. Especially in new energy vehicles, high-voltage wiring harnesses need to simultaneously undertake the dual functions of high-voltage power transmission and interlocked signal transmission. They are the key carriers for ensuring the stable operation of the vehicle's power system and safety system. Among them, the interlock structure, as the core of the safety protection of the high-voltage system, can monitor the wiring harness connection status in real time. Once a loose connection or abnormality occurs, it can quickly cut off the high-voltage circuit to avoid safety risks such as electric shock and short circuit.
[0003] For example, patent application CN217427244U in the prior art includes a high-voltage sheath, with connecting terminals internally connected to the sheath and hooks attached to the surface of the connecting terminals. A first connecting wire and a second connecting wire are connected to one side of the high-voltage sheath. A first heat-shrink tubing is attached to the surface of the first connecting wire, and a second heat-shrink tubing is attached to the surface of the second connecting wire. A circular terminal is attached to one end of the second connecting wire. An interlocking wire body is connected to one side of the high-voltage sheath, and an interlocking sleeve is attached to the surface of the interlocking wire body. The first and second connecting wires are connected to the surfaces of the connecting terminals. In this invention, by assembling an interlocking sleeve at the tail end of the interlocking wire body, it can be inserted into a connector on the circuit board to form an interlocking circuit. This not only saves operation time and facilitates operation but also improves product reliability.
[0004] However, this type of high-voltage harness has obvious defects in practical applications: the material of the interlocking wire body and the connecting wire is mainly conductive core wire, which has weak tensile strength. During vehicle driving, equipment handling, or harness installation and debugging, if subjected to external force, the interlocking wire body and the connecting wire are prone to core wire breakage or joint detachment. This can not only lead to interlocking circuit failure and false triggering of high-voltage system protection, but also interrupt power transmission, affect the normal operation of equipment, and even cause safety hazards.
[0005] Therefore, it is necessary to provide a high-voltage wire harness with an interlocking wire assembly sheath to solve the above-mentioned technical problems. Utility Model Content
[0006] This utility model provides a high-voltage wire harness with an interlocking wire assembly sheath, which solves the problem that the existing high-voltage wire harnesses have weak tensile strength of the interlocking wire body and connecting wire, and are prone to core wire breakage or connector detachment due to external force pulling, which in turn leads to interlock failure and power transmission interruption.
[0007] To solve the above-mentioned technical problems, this utility model provides a high-voltage wire harness with an interlocking wire assembly sheath, comprising: High-voltage sheath; An interlocking assembly is disposed at one end of the high-voltage sheath; Two connecting components are provided, each located at one end of the high-voltage sheath and on both sides of the interlocking component; Two reinforcing wires are fixedly installed at one end of the high-voltage sheath and located on both sides of the interlocking assembly; Multiple wire harness spacing components are respectively disposed on the outer surfaces of the interlocking component, the two connecting components, and the two reinforcing wires.
[0008] Preferably, the interlocking assembly includes an interlocking wire body, which is fixedly installed at one end of the high-voltage sheath. A terminal is fixedly installed at one end of the interlocking wire body, and an interlocking sheath is inserted into one end of the terminal.
[0009] Preferably, both of the connecting components include a connecting wire, which is fixedly installed at one end of the high-voltage sheath, and a circular terminal is fixedly installed at one end of the connecting wire.
[0010] Preferably, one end of each of the two reinforcing wires is fixedly installed on the other end of the terminal.
[0011] Preferably, the lengths of the two reinforcing wires are less than the lengths of the interlocking wire body and the two connecting wires.
[0012] Preferably, the wire harness spacing assembly includes a first clamping plate, a second clamping plate is provided on the top of the first clamping plate, through grooves are provided in the interior of both ends of the first clamping plate, elastic plates are fixedly installed at both ends of the bottom of the second clamping plate, and snap-fit blocks are fixedly installed on the bottom of the opposite side of the two elastic plates.
[0013] Preferably, the snap-fit block snaps onto the bottom of the first clamping plate.
[0014] Compared with related technologies, the high-voltage wire harness with interlocking wire assembly sheath provided by this utility model has the following beneficial effects: This utility model provides a high-voltage wiring harness with an interlocking wire assembly sheath. By setting up reinforcing wires, when the high-voltage wiring harness is subjected to external force during use, the reinforcing wires located on both sides of the interlocking assembly will bear the tension first. Since one end of the reinforcing wire is fixed to the terminal and the other end is connected to the high-voltage sheath, the tension can be directly transmitted through the reinforcing wires, avoiding stress on the interlocking wire body and the connecting wire, which are two components with weak tensile strength. In this way, the problem of core wire breakage or connector detachment caused by external force pulling is avoided, which would lead to interlock failure and power transmission interruption. This ensures the normal operation of the equipment and avoids safety hazards. Attached Figure Description

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] First Embodiment
[0019] Please refer to the following: Figure 1 , Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a high-voltage wire harness with an interlocking wire assembly sheath provided by this utility model; Figure 2 for Figure 1 The diagram shows another perspective of the structure.
[0020] A high-voltage wire harness with an interlocking wire assembly sheath includes: a high-voltage sheath 1; Interlock component 2, wherein the interlock component 2 is disposed at one end of the high-voltage sheath 1; Two connecting components 3 are provided at one end of the high-voltage sheath 1 and are located on both sides of the interlocking component 2; The two reinforcing wires 4 are both fixedly installed at one end of the high-voltage sheath 1 and located on both sides of the interlocking assembly 2; Multiple wire harness spacing components 5 are respectively disposed on the outer surfaces of the interlocking component 2, the two connecting components 3 and the two reinforcing wires 4.
[0021] Multiple wire harness spacing components 5 separate and fix the interlocking wire body 21, connecting wire 31 and reinforcing wire 4, to prevent the wire harnesses from tangling and rubbing against each other during installation or use, reduce the risk of insulation layer wear, and at the same time make the overall layout of the wire harness neat and adaptable to the narrow installation space inside the equipment.
[0022] The interlocking assembly 2 includes an interlocking line body 21, which is fixedly installed at one end of the high-voltage sheath 1. A terminal 22 is fixedly installed at one end of the interlocking line body 21, and an interlocking sheath 23 is inserted into one end of the terminal 22.
[0023] The interlock sleeve 23 is directly soldered onto the circuit board. After the interlock sleeve 23 is inserted into the interlock sleeve 23, it contacts the terminal 22 inside the interlock sleeve 23 to form an interlock circuit.
[0024] Both of the connecting components 3 include a connecting wire 31, which is fixedly installed at one end of the high-voltage sheath 1, and a circular terminal 32 is fixedly installed at one end of the connecting wire 31.
[0025] One end of each of the two reinforcing wires 4 is fixedly installed at the other end of the terminal 22.
[0026] The lengths of the two reinforcing wires 4 are less than those of the interlocking wire body 21 and the two connecting wires 31.
[0027] The working principle of the high-voltage wire harness with interlocking wire assembly sheath provided by this utility model is as follows: When high-voltage wiring harnesses are installed in new energy vehicles or industrial equipment, the conductors inside the high-voltage sheath 1 carry high-voltage power transmission. The interlocking wire body 21 of the interlocking assembly 2 is connected to the interlocking sheath 23 through the terminal 22 to form an interlocking circuit and monitor the wiring harness connection status in real time. The connecting wires 31 of the two connecting assemblies 3 are connected to the high-voltage interface of the external equipment through the circular terminal 32 to assist in power transmission or signal interaction. When the wiring harness is pulled by an external force, the reinforcing wires 4 located on both sides of the interlocking assembly 2 bear the tension first. Since one end of the reinforcing wire 4 is fixed to the terminal 22 and the other end is fixed to the high-voltage sheath 1, the tension is transmitted through the reinforcing wire 4, avoiding the interlocking wire body 21 and the connecting wire 31 from being stressed. At the same time, the length of the reinforcing wire 4 is shorter than that of the interlocking wire body 21 and the connecting wire 31, ensuring that the reinforcing wire is in a slack state under normal docking conditions, and does not affect the docking accuracy of the terminal 22 with the interlocking sheath 23 and the circular terminal 32; it only tightens when under stress, playing a tensile resistance role and protecting the conductive core wire from damage.
[0028] Compared with related technologies, the high-voltage wire harness with interlocking wire assembly sheath provided by this utility model has the following beneficial effects: By setting up the reinforcing wire 4, when the high-voltage harness is subjected to external force during use, the reinforcing wire 4 located on both sides of the interlocking assembly 2 will bear the tension first. Since one end of the reinforcing wire 4 is fixed to the terminal 22 and the other end is connected to the high-voltage sheath 1, the tension can be directly transmitted through the reinforcing wire 4, avoiding the interlocking wire body 21 and the connecting wire 31, which are two components with weak tensile strength, from being subjected to force. In this way, the problem of core wire breakage or connector detachment caused by external force pulling is avoided, which would lead to interlock failure and power transmission interruption, thereby ensuring the normal operation of the equipment and avoiding safety hazards.
[0029] Second Embodiment
[0030] Please refer to the following: Figure 3 and Figure 4 Based on the first embodiment of this application providing a high-voltage wiring harness with an interlocking wire assembly sheath, the second embodiment of this application proposes another high-voltage wiring harness with an interlocking wire assembly sheath. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.
[0031] Specifically, the second embodiment of this application provides a high-voltage wire harness with an interlocking wire assembly sheath, which differs in that the wire harness spacing assembly 5 includes a first clamping plate 51, a second clamping plate 52 is provided on the top of the first clamping plate 51, through grooves 53 are provided inside both ends of the first clamping plate 51, elastic plates 54 are fixedly installed at both ends of the bottom of the second clamping plate 52, and snap-fit blocks 55 are fixedly installed on the bottom of the opposite side of the two elastic plates 54.
[0032] The snap-fit block 55 snaps into the bottom of the first clamping plate 51.
[0033] The through slot 53, the elastic plate 54 and the snap-fit block 55 work together to make the elastic snap-fit structure easy to operate during use. Installation and disassembly can be completed without tools, which is suitable for wire harness debugging or maintenance needs. Both the first clamping plate 51 and the second clamping plate 52 are made of flame-retardant plastic material, which improves the fire resistance of the wire harness and further ensures the safety of the high-voltage system.
[0034] The working principle of the high-voltage wire harness with interlocking wire assembly sheath provided by this utility model is as follows: When installing the wire harness spacing assembly 5, place the interlocking wire body 21, connecting wire 31 and reinforcing wire 4 into the preset slots of the first clamping plate 51 respectively, ensuring that each wire harness is parallel to each other and does not contact each other. Cover the top of the first clamping plate 51 with the second clamping plate 52, so that the elastic plate 54 at the bottom of the second clamping plate 52 is aligned with the through slot 53 of the first clamping plate 51. Press the second clamping plate 52 down, and the elastic plate 54 will deform under the force and pass through the through slot 53 until the snap-fit block 55 at the bottom of the elastic plate 54 snaps into the bottom of the first clamping plate 51, thus completing the fixation of the first clamping plate 51 and the second clamping plate 52.
[0035] Compared with related technologies, the high-voltage wire harness with interlocking wire assembly sheath provided by this utility model has the following beneficial effects: By setting the wire harness spacing component 5, the wire harnesses can be physically separated during use, thus keeping them neat, avoiding mutual friction, reducing the risk of insulation damage, and extending the service life of the wire harnesses.
