Dual-thread seal high-strength F type coaxial cable connector

Abstract

The invention relates to a dual-thread seal high-strength F type coaxial cable connector which is used for connecting a coaxial cable to an equipment interface. The coaxial cable connector comprises a connecting nut, a connector body and an elastic connecting body, wherein the connector body is provided with rear-section threads and front-section taper threads; the rear-section threads are matched and connected with a cable insulator; the front-section taper threads are used for being spirally connected with a cable sheath layer which is hermetically matched and connected with a cable sheath; the rear-section threads are used for being spirally connected with the cable insulator, so that the cable insulator is hermetically matched and connected with the connector body; a rear inner taper section and a front inner taper section are arranged between the rear-section threads and the front-section taper threads; the rear inner taper section is used for accommodating the outer conductor of the cable and closely connecting the outer conductor with the connector body so as to form good electric contact; and the front inner taper section is used for accommodating the cable sheath layer screwed in by the front-section taper threads, so that the cable sheath is closely connected with the body and hermetically matched and connected with the cable sheath. The coaxial cable connector has the advantages of compact structure, convenient insertion, simple operation, stable mechanical performance and electric performance, and the like and is very suitable for connection of wired cable.

Description

technical field [0001] The invention relates to a high-strength F-type coaxial cable connector with double-thread sealing, which is used for connecting the coaxial cable to the interface of equipment. Background technique [0002] Chinese patent CN1200480 discloses a coaxial cable connector. Its structure and connection principle are as follows: it includes a nut, a tube shaft, a body and a compression sleeve; when the end of the coaxial cable is inserted into the connector nut When the leading end of the tube shaft is pushed through the guide hole of the main body, the tube shaft will separate the outer protective layer and conductive mesh layer of the coaxial cable from the insulating layer, so that the barb part of the tube shaft is inserted between the two; when pressed together When the sleeve is advanced on the grooved body, it can press the outer layer of the coaxial cable and the conductive mesh layer in two places. This structure has the following disadvantages: ①....

Problems solved by technology

This structure has the following disadvantages: ①. Since the tube shaft needs to be inserted upside down into the outer conductor layer between the outer sheath layer and the insulating layer, since the coaxial outer conductor is mostly a braided aluminum foil or copper foil structure, the aluminum foil or copper foil is Aluminum-plastic composite or copper-plastic composite, and the plastic film layer is close to the insulating layer, so the tube shaft is easily inserted between the plastic film and the insulation during assembly, resulting in poor contact between the cable and the connector; ②, this type of connector and Insufficient connection force of the coaxial cable
