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

The reliable coaxial cable connector of a kind of clamping

Technical field

The present invention relates to a kind of cable connecting arrangement, especially relate to the reliable coaxial cable connector of a kind of clamping.

Background technology

As everyone knows, the connection between coaxial cable is connected on the termination of coaxial cable by coaxial cable connector conventionally, cable can be connected on various electronic equipments like this to for example broadcast receiver, television set etc.The center of coaxial cable is provided with cored wire conductor, and the periphery of cored wire conductor is coated with insulating barrier, screen and rubber cover from inside to outside successively.Current coaxial cable connector comprises conical pipe, attaching nut, connector and lining core pipe, one end of lining core pipe is conical head, the other end is provided with outward flange, attaching nut is threaded connection outside connector, the end of the connector of conical pipe clamping, the center of coaxial cable is provided with cored wire conductor, the periphery of cored wire conductor is coated with insulating barrier from inside to outside successively, screen and rubber cover, cored wire conductor, insulating barrier inserts in lining core pipe from the taper head end of lining core pipe together with screen, cored wire conductor stretches out from attaching nut's center, rubber cover is enclosed within outside lining core pipe, C type clip is stuck in outside rubber cover, by specific purpose tool, rear locking is tightened up in the open end of C type clip, thereby rubber cover is fastened on the outer wall of lining core pipe, after this, can this coaxial cable be connected with the radio-frequency terminals of other coaxial cables or electric equipment by attaching nut.This coaxial cable connector, tightens up in a side of C type clip, makes the outer tube distortion that is squeezed, annular gap between outer tube and lining core pipe becomes inhomogeneous, within unwarrantable one week, all can contact well with lining core pipe, cause shielding bad, loss of signal is large, transmits unstablely, is easily disturbed; In addition, the contact area between C type clip and rubber cover is less, blocks to such an extent that tension easily damages rubber cover, blocks too loosely easily to come off, and it is unreliable to make to connect.

Summary of the invention

The invention provides the reliable coaxial cable connector of a kind of clamping, unreliable to solve the connection of prior art standard coaxial cable, shield bad problem, coaxial cable is connected reliable, shielding is good.

For solving above technical problem, technical scheme of the present invention is, provide a kind of clamping reliable coaxial cable connector, comprise conical pipe, attaching nut, connector and lining core pipe, one end of lining core pipe is conical head, the other end is provided with outward flange, attaching nut is threaded connection outside connector, the end of the connector of conical pipe clamping, the center of coaxial cable is provided with cored wire conductor, the periphery of cored wire conductor is coated with insulating barrier from inside to outside successively, screen and rubber cover, cored wire conductor, insulating barrier inserts in lining core pipe from the taper head end of lining core pipe together with screen, cored wire conductor stretches out from attaching nut's center, rubber cover is enclosed within outside lining core pipe, it is characterized in that, the outside of lining core pipe is provided with outer tube, the afterbody of outer tube is socketed with tail cover, the outer wall of tail cover and the inwall of outer tube are suitable, the inwall of tail cover is provided with type conical bench, type conical bench is pressed on rubber cover on the outer wall of lining core pipe.

Adopt above structure, lining core pipe pushes from left to right in rubber cover, and tail cover is pressed on rubber cover on lining core pipe in circle direction from right to left equably, and connection is reliable and shielding is good.

As a further improvement on the present invention, connector and outer tube between end face, be provided with in opposite directions sealing ring.Arrange after sealing ring, this coaxial cable connector has water resistance.

Accompanying drawing explanation

Fig. 1 is the structural representation before coaxial cable of the present invention inserts;

Fig. 2 is the structural representation after coaxial cable of the present invention inserts;

In figure: 1 conical pipe, 2 attaching nuts, 3 connectors, 4 sealing rings, 5 lining core pipes, 6 outer tubes, 7 tail covers, 8 cored wire conductors, 9 insulating barriers, 10 screens, 11 rubber covers.

Embodiment

As shown in Figure 1, the reliable coaxial cable connector of clamping of the present invention, comprise conical pipe 1, attaching nut 2, connector 3 and lining core pipe 5, one end of lining core pipe 5 is conical head, the other end is provided with outward flange, attaching nut 2 is threaded connection outside connector 3, the end of the connector 3 of conical pipe 1 clamping, the outside of lining core pipe 5 is provided with outer tube 6, connector 3 and outer tube 6 between end face, be provided with in opposite directions sealing ring 4, the afterbody of outer tube 6 is socketed with tail cover 7, and the outer wall of tail cover 7 and the inwall of outer tube 6 are suitable, and the inwall of tail cover 7 is provided with type conical bench.

As shown in Figure 2, the center of coaxial cable is provided with cored wire conductor 8, and the periphery of cored wire conductor 8 is coated with insulating barrier 9, screen 10 and rubber cover 11 from inside to outside successively.When connection; the rubber cover of coaxial cable 11, screen 10 and insulating barrier 9 are clipped to a part in succession; expose cored wire conductor 8; make the termination of coaxial cable be from inside to outside stairstepping distribution; cored wire conductor 8, insulating barrier 9 insert in lining core pipe 5 from the taper head end of lining core pipe 5 together with screen 10; cored wire conductor 8 stretches out from attaching nut 2 center, in the annular chamber of rubber cover 11 between lining core pipe 5 and outer tube 6.
