Description

Technical Field

[0001] The present application belongs to the technical field of combiners, and specifically relates to a communication vehicle combiner and a combiner connection assembly. Background Art

[0002] A combiner is a device used to combine multiple signals or paths into one signal or path. In a communication vehicle, the main function of the combiner is to combine signals from multiple radio frequency sources into one signal, which can reduce the number of antennas, optimize system performance, and simplify system design.

[0003] Combiner connection components are used to connect the combiner to other RF devices (such as transmitters, receivers and antennas). These components ensure smooth signal transmission and provide the necessary electrical and mechanical interfaces. They mainly include RF coaxial cables, connectors, cable adapters and feeders.

[0004] For example, the announcement number CN217656050U is a combiner for wireless communications, comprising a combiner body, reinforced connection structures at both ends of the combiner body, and a shock-absorbing heat dissipation structure at the lower end of the combiner body, characterized in that the reinforced connection structure comprises: four threaded sleeves, four operating nuts, four connecting cables, four connecting sleeves and a plurality of connecting bolts; the utility model relates to the technical field of combiners, and the beneficial effects of this case are: the reinforced connection structure adopted in this case reinforces the connection position between the line and the combiner, avoiding separation of the line and the combiner due to shaking or pulling, and ensuring that the combiner can be used normally; at the same time, the adopted shock-absorbing heat dissipation structure reduces the vibration received by the combiner through the provided buffer plate, and dissipates heat from the lower end of the combiner body through the provided heat dissipation component, avoiding the generation of high temperature in the combiner body, etc.

[0005] However, in actual use, it was found that: the device ensures the stability of the connecting cable by tightening the connecting bolts, thereby preventing the cable from being damaged or falling off under pulling;

[0006] However, when the connecting bolts are tightened too much, excessive squeezing force will be applied to the cables, thereby affecting the cables. If the bolts are tightened too loosely, the connection will still be affected when the cables are pulled. Therefore, a communication vehicle combiner and a combiner connection assembly are provided. Utility Model Content

[0007] The purpose of this application is to provide a communication vehicle combiner and a combiner connection assembly in order to solve the above-mentioned problems.

[0008] The technical solution adopted in this application is as follows: a communication vehicle combiner and a combiner connection assembly, including a combiner body, a cable connector fixedly installed on the front side of the combiner body, and connection fixing plates fixedly installed on the left and right sides of the combiner body by set screws respectively, a U-shaped mounting plate fixedly installed on one side of the connection fixing plate, a circular wire threading hole opened on the front side of the U-shaped mounting plate, a fixing bolt threadedly connected to the top surface of the U-shaped mounting plate, the bottom end of the fixing bolt extends to the inside of the circular wire threading hole, and a circular rubber pad is fixedly installed on the bottom end of the fixing bolt.

[0009] In a preferred embodiment, a rectangular frame is fixedly installed on the bottom surface of the combiner body, and a plurality of heat dissipation fins are installed in an evenly spaced array inside the rectangular frame on the bottom surface of the combiner body. A plurality of ventilation holes are respectively provided on the front and rear sides of the rectangular frame.

[0010] In a preferred embodiment, fixing plates are fixedly installed on the left and right sides of the rectangular frame respectively, and mounting holes are opened on the top surfaces of the fixing plates.

[0011] In a preferred embodiment, a second power cable connector is fixedly mounted on the rear side of the combiner body.

[0012] In a preferred embodiment, an arc-shaped bottom plate is fixedly installed near the inner wall surface of the bottom of the circular threading hole.

[0013] In a preferred embodiment, a rotating end is fixedly mounted on the top end of the fixing bolt.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0015] 1. In the present application, due to the adoption of the above-mentioned solution, the operator pulls the cable toward the cable connector so that its end forms an arc. Then, the rotating end drives the fixing bolt to rotate, thereby moving the circular rubber pad downward and tightening the cable. This can effectively fix the cable, and in subsequent use, when the cable is subjected to pulling force, the arc-shaped connector will expand to buffer the pulling force and reduce the risk of detachment or damage. The device can quickly and effectively fix the cable and protect the cable from pulling damage. BRIEF DESCRIPTION OF THE DRAWINGS
