Coaxial cable connector reliable in clamping operation

Abstract

The invention discloses a coaxial cable connector reliable in clamping operation and belongs to the technical field of cable connectors. The coaxial cable connector comprises a taper tube, a connecting nut, a joint and a lining tube. One end of the lining tube is a taper head and the other end of the lining tube is provided with an outer flange. The connecting nut is connected outside the joint through threads. The taper tube is clamped at the end of the joint. A core wire conductor is arranged in the center of the coaxial cable and coated with an insulating layer, a shielding layer and a rubber protective layer sequentially from inside to outside. The core wire conductor, the insulating layer and the shielding layer are inserted in the lining tube together from the taper head end of the lining tube. The core wire conductor extends out of the center of the connecting nut. The lining tube is sleeved with the rubber protective layer. An outer casing tube is arranged outside the lining tube. A sealing ring is arranged between the opposite end faces of the joint and the outer casing tube. The tail portion of the outer casing tube is provided with a tail sleeve in a sleeved mode. The outer wall of the tail sleeve is matched with the inner wall of the outer casing tube. The inner wall of the tail sleeve is provided with a taper step. The rubber protective layer is pressed onto the outer wall of the lining tube through the taper step. The lining tube is extruded into the rubber protective layer from left to right. The rubber protective layer is evenly pressed onto the lining tube in the whole circumferential direction from right to left through the tail sleeve. The coaxial cable connector reliable in clamping operation is reliable in connection and good in shielding effect.

Description

technical field [0001] The invention relates to a cable connection device, in particular to a coaxial cable connector with reliable clamping. Background technique [0002] As we all know, the connection between coaxial cables is usually connected to the ends of the coaxial cables through coaxial cable connectors, so that the cables can be connected to various electronic devices, such as radios, televisions and so on. The center of the coaxial cable is provided with a core wire conductor, and the outer periphery of the core wire conductor is covered with an insulating layer, a shielding layer and a rubber protective layer in sequence from the inside to the outside. The current coaxial cable connector includes a tapered tube, a connecting nut, a connecting head and a core tube. One end of the core tube is a tapered head, and the other end is provided with an outer flange. The connecting nut is threaded outside the connecting head. At the end of the connector where the tapered...
