Description

Technical Field

[0001] The invention relates to the technical field of wire harnesses, in particular to a wire harness composed of multiple wire harnesses. Background Art

[0002] The wiring harness is the main network of the automobile circuit. Without the wiring harness, there would be no automobile circuit. The wiring harness refers to the contact terminal made of copper material, which is crimped with the wires and cables, and then the insulator is plastic-pressed on the outside or a metal shell is added. The wiring harness industry chain includes wires and cables, connectors, processing equipment, wiring harness manufacturing and downstream application industries. The wiring harness is widely used and can be used in automobiles, household appliances, computers and communication equipment, various electronic instruments and meters, etc. The body wiring harness connects the entire body and is generally H-shaped.

[0003] After the existing automobile wiring harness is connected, it is traditionally necessary to wrap cloth-based tape around the outside of the wiring harness. When the wiring harness needs to be troubleshooted, the cloth-based tape needs to be completely removed, and each wire in the wiring harness needs to be checked and tested one by one to find the specific part causing the problem. Then, when in use, the cloth-based tape is used to wrap the combined wiring harness bodies together. Since the cloth-based tape cannot be used again after being removed, the wiring harness is less convenient to repair. Therefore, a wiring harness with multiple wiring harnesses is proposed. Summary of the invention

[0004] The object of the present invention is to provide a wiring harness composed of multiple wiring harnesses to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a wire harness of a multi-wire harness combination, comprising a corrugated tube, both ends of the corrugated tube are bonded with rubber rings, a placement cavity is provided inside the corrugated tube, a plurality of wire harness bodies are provided inside the placement cavity, male terminals and female terminals are electrically connected to the ends of the plurality of wire harness bodies, a connection component is provided on one side of the corrugated tube, and a sealing component is provided on one side of the connection component;

[0006] The connecting assembly comprises a fixing frame and a limiting plate, a locking groove is provided on one side of the limiting plate, a limiting groove is provided on one side of the fixing frame, and a first sliding groove and a second sliding groove are respectively provided inside the fixing frame.

[0007] Preferably, a locking rod inserted into the inner side of the locking groove is slidably connected to the inner side of the second sliding groove, and a pulling plate is fixed to one end of the locking rod.

[0008] Preferably, a first slide plate fixed to one side of the locking rod is slidably connected to the inner side of the first slide groove, and a second spring is connected between one side of the first slide plate and the inner side of the first slide groove.

[0009] Preferably, the outer side of the limiting plate is inserted into the inner side of the limiting groove, the inner side of the limiting groove is slidably connected with a push plate, and a first spring is connected between one side of the push plate and the inner side of the limiting groove.

[0010] Preferably, the sealing assembly comprises four second slide plates, a second sealing ring is bonded to one side of the second slide plate, and the second sealing ring is attached to the outer side of the male terminal at a side away from the second slide plate.

[0011] Preferably, a mounting groove is provided on one side of the male terminal, the mounting groove is in a U-shape, and a first sealing ring is bonded to the inner side of the mounting groove.

[0012] Preferably, four third slide grooves are provided inside the female terminal, the outer side of the second slide plate is slidably connected to the inner side of the third slide groove, and a third spring is connected between one side of the second slide plate and the inner side of the third slide groove.

[0013] Preferably, the outer side of the first sealing ring is attached to one end of the female terminal, and the outer side of the male terminal is adapted to the inner side of the female terminal.

[0014] Preferably, one side of the fixing frame and the limiting plate are integrally formed on one side of the corrugated pipe, and the limiting plate is in the shape of a cuboid.

[0015] Compared with the prior art, the present invention adopts the above technical solution and has the following technical effects:

[0016] 1. When the male terminal and the female terminal are plugged in, first, the first sealing ring on the inner side of the mounting groove on one side of the male terminal is fitted onto one end of the female terminal. When the male terminal is inserted into the inner side of the female terminal, the male terminal slides over the inner side of the second sealing ring. Under the elastic force of the third spring, the second sealing ring is sealed and slides on the outer side of the male terminal. The first sealing ring and the second sealing ring are used to double seal the gap between the male terminal and the female terminal, which can effectively prevent water, moisture and other liquids from penetrating into the gap of the connector, thereby preventing short circuits, corrosion and damage that may be caused by the wires being exposed to a humid environment, and improving the reliability of the male and female terminals during connection.

[0017] Second, by pulling the pull plate to one side, the pull plate drives the locking rod to slide inside the second slide groove, and the locking rod drives the first slide plate to compress the second spring. At this time, the locking rod leaves the inside of the lock groove, and the corrugated tube wrapped around the outside of multiple wiring harness bodies can be easily removed. The operation is simple and convenient, and it is avoided that after using cloth-based tape to wrap multiple wiring harness bodies, when it is necessary to troubleshoot the wiring harness bodies, it is necessary to remove all the cloth-based tapes, check and test each wire in the wiring harness body one by one, find the specific part causing the problem, and then use the cloth-based tape to wrap the combined wiring harness bodies together, and use the connecting assembly to connect the corrugated tube, so that the wiring harness body can be easily removed from the outside of the wiring harness body when troubleshooting, which improves the convenience of the wiring harness body during maintenance. At the same time, the corrugated tube can be reused many times, reducing the maintenance cost of the wiring harness body during maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
