Description

Connector insulating housing

Technical Field

The utility model relates to the technical field of connector insulating shells, in particular to a connector insulating shell.

Background

N-type and L16-type connectors are widely used in radio frequency and microwave transmission systems. The cable assembly of the N-type or L16-type connector and the coaxial cable is necessary for connecting a microwave source and transmitting signals (power). Usually, the diameters of the N-type and L16-type male screw sleeves are about 20mm, and in practical application, the male screw sleeves are difficult to directly screw by hands, and are inconvenient to use by means of an outer hexagonal wrench. By installing the insulating housing according to the present invention, a close fit between the male end of an N-type or L16-type connector and the source of the device can be achieved by hand. The screw sleeves of the N-type and L16-type connectors are made of metal and are directly communicated with the radio frequency microwave system, and by installing the insulating shell related to the invention, operators can be prevented from being shocked and damage to system equipment caused by environmental static electricity can be avoided. The N-type and L16-type connector insulating housings can be applied to almost all scenarios using N-type and L16-type connectors.

The existing N-type and L16-type connector male heads are used by only installing a simple silica gel ring or not installing an insulating shell. This case has the following disadvantages:

The male screw sleeve of the N-type and L16-type connectors is only about 20mm in size, and when the cable assembly is connected with equipment, the tightening and the loosening are labor-consuming, and the assembly and disassembly processes are labor-consuming and low in efficiency.

2. When a cable assembly provided with an N-type or L16-type male connector is installed for equipment by hand, the cable assembly is often not installed in place, and the tight fit effect between the cable assembly and the equipment is not achieved.

3. The connection part of the coaxial cable and the tail part of the N-type or L16-type connector is easy to be pulled and extruded by external force to damage the structure of the coaxial cable, so that the cable transmission effect is poor.

4. When the output power of the device is high or the device is used for a long time, the temperature of the N-type or L16-type connector is increased, and the device is in risk of scalding during disassembly.

The N-type and L16-type connector threaded sleeves are made of metal, are directly communicated with the radio frequency microwave system, and when the cable assembly is installed by hands, the risk that an operator is injured accidentally exists, and the risk that equipment devices are damaged due to the environment static electricity introducing system exists. Therefore, a new solution is needed.
