Description

Technical Field

[0001] The utility model relates to the technical field of connector insulating shells, and more specifically to a connector insulating shell. Background Art

[0002] N-type and L16-type connectors are widely used in radio frequency and microwave transmission systems. The cable assembly in which the N-type or L16-type connector is assembled with the coaxial cable is a necessary component for connecting the microwave source and transmitting signals (power). Usually, the diameter of the N-type and L16-type male screw sleeves is about 20 mm. In practical applications, it is difficult to tighten them directly by hand, and using an external hexagonal wrench is not convenient enough. By installing the insulating shell involved in the present invention, the tight fit between the N-type or L16-type connector male and the equipment source can be achieved by hand. The N-type and L16-type connector screw sleeves are made of metal and are directly connected to the radio frequency microwave system. By installing the insulating shell involved in the present invention, the operator can be protected from electric shock and damage to the system equipment caused by environmental static electricity can be avoided. The N-type and L16-type connector insulating shells can be applied to almost all scenarios where N-type and L16-type connectors are used.

[0003] Currently, the male connectors of N-type and L16-type connectors are not installed with insulating shells or are only installed with simple silicone rings. This has the following disadvantages:

[0004] 1. The male screw sleeve of N-type and L16-type connectors is only about 20mm in size. When the cable assembly is connected to the equipment, it is very difficult to tighten it by hand, and the loading and unloading process is laborious and inefficient.

[0005] 2. When manually installing a cable assembly with an N-type or L16 male connector on a device, it is often not installed properly, and the tight fit between the cable assembly and the device cannot be achieved.

[0006] 3. The part where the coaxial cable is connected to the tail of the N-type or L16 connector is easily pulled or squeezed by external force, which may damage the structure of the coaxial cable and cause the cable transmission effect to deteriorate.

[0007] 4. When the device has a high output power or has been used for a long time, the temperature of the N-type or L16-type connector rises, and there is a risk of burns when removing it.

[0008] 5. The N-type and L16-type connector screw sleeves are made of metal and are directly connected to the RF microwave system. When installing the cable assembly by hand, there is a risk of accidental injury to the operator and a risk of damage to the equipment components due to the introduction of environmental static electricity into the system. Therefore, a new technical solution is needed to solve this problem. Utility Model Content
