[0002] Cars are very common in modern life. There are many wiring harnesses inside the car for transmitting signals and energy. The wiring harnesses are connected to each other through wiring harness interfaces. In the prior art, two wiring harness interfaces are connected to each other through internal and external threads.

[0003] For example, the publication number CN218549480U discloses an automotive wiring harness connection interface, including a first interface and a second interface, wherein the axial side wall of one end of the first interface close to the second interface is fixedly connected with a connecting rod, and the radial side wall of the connecting rod at one end away from the second interface is provided with a groove, and the radial side wall of the second interface is provided with a first chamber, and a positioning ring is slidably installed on the inner wall of the first chamber, and the radial outer wall of the positioning ring is provided with an oblique groove. The utility model fixes the connecting rod and the first interface and the second interface at the same time by setting a positioning ring, and the protruding part of the oblique groove in the positioning ring cooperates with the inner wall of the groove to fix the connecting rod, thereby solving the technical problem that the two wiring harness interfaces in the prior art are connected to each other by internal and external threads, and it is particularly inconvenient for maintenance personnel to disassemble and install the wiring harness interfaces connected by threads, so that the wiring harness interface can be quickly fixed, effectively saving the time of disassembling the wiring harness interface during automobile line maintenance.

[0004] However, in the prior art, conventional wiring harness interfaces do not use effective sealing components to seal the gaps at the interfaces, and external water and water vapor from inside the car may enter the gaps at the interfaces, causing a short circuit, and the safety of the device is limited to a certain extent. Utility Model Content

[0005] The utility model aims to solve the problem that the conventional wiring harness interface in the prior art does not adopt an effective sealing component to seal the gap at the interface, which easily causes a short circuit.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a signal transmission harness interface, comprising a first interface and a second interface, the inner side of the first interface is symmetrically fixedly connected with a first connector, the inner side of the second interface is symmetrically fixedly connected with a second connector, the first connector and the second connector are fixedly connected via a sealing assembly, the upper surfaces of the first connector and the second connector are both provided with threaded holes, the sealing assembly comprises a mounting block, both sides of the mounting block are respectively provided with mounting holes for plugging with the first connector and the second connector, through holes are symmetrically provided on both sides of the upper surface of the mounting block, a threaded rod A is plugged in the middle of the through hole, a threaded rod B is threadedly connected at the axis of the mounting block, and a sealing ring is fixedly connected to one end of the threaded rod B.

[0007] As a preferred embodiment, a first joint is fixedly connected to the axis center of the inner side of the first interface, a second joint is fixedly connected to the axis center of the inner side of the second interface, and the first joint is sleeved with the second joint.

[0008] As a preferred embodiment, a first connecting rod is symmetrically fixedly connected to one side of the inner side of the first interface close to the first connecting member, and a second connecting rod is symmetrically fixedly connected to one side of the inner side of the second interface close to the first connecting member.

[0009] As a preferred implementation, the first connecting rod and the second connecting rod are fixedly connected via a fastening assembly, and the fastening assembly includes a positioning rod.

[0010] As a preferred implementation, openings are provided on both sides of the positioning rod, and threads are provided on surfaces of the openings.

[0011] As a preferred embodiment, a nut is threadedly connected to the surface of the thread.

[0012] As a preferred implementation, a sealing ring is symmetrically fixedly connected to the lower surface of the sealing ring.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. The utility model adopts a sealing component to seal the gap at the interface of the wiring harness to prevent the entry of external moisture and water vapor. When the first interface and the second interface are assembled, the first connector and the second connector are inserted into both sides of the mounting block, and the first connector, the second connector and the mounting block are fixed by a threaded rod A. At the same time, the distance between the first interface and the second interface can be limited. The threaded rod B is twisted, and the threaded rod B drives the sealing ring to move downward. The two sealing rings seal the gap at the interface, thereby improving the safety of the device.

[0015] 2. The utility model adopts a fastening component to avoid looseness at the interface connection. When the first interface and the first interface are assembled, the second connecting piece and the first connecting rod are inserted into the two ends of the positioning rod, and the two sets of nuts are rotated from the inside to the outside on the surface of the thread, so as to fix the distance between the first interface and the second interface, making the connection between the first interface and the second interface more stable.
