Description

Technical Field

[0001] The utility model relates to the technical field of connecting wire harnesses, in particular to a connecting wire harness based on vehicle-mounted navigation. Background Art

[0002] The automotive wiring harness is the network body of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the component that is formed by crimping the contact terminals made of copper materials with the wires and cables, and then plastic-pressing the insulators or adding metal shells on the outside to form a connecting circuit.

[0003] Publication No. CN213425225U discloses a connection harness based on vehicle navigation, including a harness head and an anti-entanglement device, wherein the harness head is electrically connected to the harness branch through the harness, grooves are provided on both sides of the top of the harness head, and the harness head is connected to the card cover through the grooves; the anti-entanglement device is used to prevent the anti-entanglement device from being connected to the harness. Although this type of connection harness places the harness through the placement groove inside the anti-entanglement device, and there is a distance gap between the placement grooves to effectively prevent the harness from being entangled, this type of connection harness can only adapt to harness branches of specific sizes and models, which results in the need to use a variety of different fixing devices when processing harnesses of different models or sizes. This limitation not only increases the cost of the equipment, but also reduces work efficiency, because the fixing device needs to be frequently replaced to adapt to different harness branches. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a connection harness based on vehicle navigation, comprising a harness head, a harness branch head is fixedly installed on the bottom surface of the harness head, a harness body is fixedly installed on the bottom end of the harness branch head, a clamping block A and a clamping block B are sleeved on the surface of the harness branch head, a placement groove is provided on the opposite sides of the clamping block A, a sliding rod is penetrated on the top surface of the clamping block A, a pressure block is fixedly installed on one end of the sliding rod, a top plate is fixedly installed on the other end of the sliding rod, and a tension spring is fixedly connected between the top plate and the clamping block A.

[0006] Preferably, a handle is fixedly mounted on the top surface of the top plate, and the handle is made of PC plastic. Here, the top plate can be pulled conveniently.

[0007] Preferably, the block A and the block B are rotationally connected, and the slide bar and the block A are slidingly connected.

[0008] Preferably, the placement grooves are arranged at equal distances on the surfaces of the card block A and the card block B, and fixing bolts are inserted into the top surfaces of the card block A and the card block B. Here, the card block A and the card block B can be firmly fixed.

[0009] Preferably, the card block A and the card block B are the same in size and shape.

[0010] Preferably, the top surface of the wiring harness head is provided with a protection mechanism, the protection mechanism includes a card cover, the card cover is provided on the top surface of the wiring harness head, a magnet is fixedly installed on the top surface of the wiring harness head, and a round handle is fixedly installed on the top surface of the card cover. Here, the wiring harness head can be protected.

[0011] Preferably, the material of the card cover is ferrite stainless steel, and the magnets are symmetrically distributed on the top surface of the wiring harness head. Here, the structural strength of the card cover can be improved.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the present utility model, when it is actually used and it is necessary to prevent the wiring harness branch from being entangled, it is only necessary to put the wiring harness branch into the placement groove between the card block A and the card block B, and then close the card block A and the card block B, and then screw the fixing bolt into the card block A and the card block B to lock the card block A and the card block B. At this time, the wiring harness branch can be fixed in the placement groove, and the wiring harness branch can be prevented from being entangled and knotted by the separation of the placement groove. At the same time, due to the tension of the tension spring, the tension spring can pull the top plate to move downward, and the top plate then drives the slide bar to move downward, and the slide bar then drives the pressure block to move until the pressure block presses the wiring harness branch. At this time, the wiring harness branch can be fixed more firmly, and it can adapt to wiring harnesses of different models and sizes. The utility model adopts a dynamic clamping mechanism composed of a tension spring, a top plate, a slide bar and a clamping block. The design can adapt to different models and sizes of wiring harness headers. This adaptive ability increases the versatility of the design and reduces the restrictions on specific wiring harness sizes, so that the same device can be used in a variety of different application scenarios. The clamping blocks A and B are locked by fixing bolts, and the wiring harness header is firmly pressed by the clamping block. This design ensures the stability of the wiring harness during vehicle operation. This fixing method can effectively prevent the loosening or displacement of the wiring harness due to vehicle vibration, thereby improving the reliability of the connection.

[0014] 2. In the present invention, in actual use, the harness head can be protected by the card cover. When using the card cover, you only need to align the card cover with the harness head and insert it until the card cover fits the magnet. At this time, the magnet can attract the card cover made of ferrite stainless steel. At this time, the card cover can be fixed on the harness head. When the card cover needs to be opened, you only need to pull the card cover outward through the round handle to remove the cover. The present invention makes the connection and separation between the card cover and the harness head simpler and faster through magnetic fixation. The user only needs to bring the two close together, and the magnetic force can automatically attract them to fit tightly together without manually aligning the grooves or using additional tools. This is especially useful for frequent installation and removal of harnesses, which greatly improves the convenience of operation. Compared with mechanical connection methods such as physical buckles, magnetic fixation reduces the wear of physical contact, extends the service life of the card cover and the harness head, and is highly practical.
