Description

Cable connector

[technical field]

The utility model relates to a kind of cable connector, refers to a kind of cable connector that also can keep the good electrical transmission performance in communication equipment and the wireless instruments in order to transmitting radio frequency signal that is applied in especially.

[background technology]

In the loop of rf of communication equipment and wireless instruments, in electronic installations such as notebook computer, coaxial cable transmitting radio frequency signal commonly used, cable connector is made up of coaxial cable and end fitting usually.Described coaxial cable generally is made up of the center conductor of arranging ringwise, insulator, knitted body and insulation sheath, end fitting then is made up of columnar member, blowout patche and fit assembly, described fit assembly is nested with on coaxial cable, and the two inserts in the columnar member jointly.Fit assembly commonly used comprises first and second sleeve pipes of coaxial setting, it is nested with respectively successively on center conductor and knitted body, characteristic impedance for balanced coaxial cable, need to excise separately the insulator between center conductor and the knitted body, the outside turnup of knitted body is coated to the outer surface of second sleeve pipe, but the operation of the insulator that excises knitted body separately and coated, coaxial cable for thin type softness, particularly difficult, and very easily damage very thin center conductor in the wire stripping process again, thereby have a strong impact on the quality that electrically contacts in the anabolic process, can't guarantee good electric property.The length of columnar member commonly used in addition is shorter, causes and assembly that it connects and the distance between the circuit part fall short of, and the EMI effect is bigger.And on the columnar member with the plug mating part, all adopt and near the identical right-handed thread of other connector the damage that very easily causes circuit or components and parts short circuit like this because of error.

[summary of the invention]

The purpose of this utility model is to provide a kind of and improves the clamp mode, improves the cable connector that wire stripping efficient guarantees the good electrical performance and can effectively prevent error.

The purpose of this utility model is achieved in that the utility model comprises connector body, coaxial cable and is nested with on coaxial cable and is contained in fit assembly in the connector body.The coaxial double-screw bolt that is provided with of wherein said connector body, its outer surface are provided with the left hand thread that can prevent the mistake assembling, and the length of connector body is longer than cable connector main body commonly used.Establish center conductor in the coaxial cable, and from inside to outside radially be coated with insulating barrier, braid and the insulation sheath of annular successively.The fit assembly is arranged ringwise, has coaxially to each other first sleeve pipe, second sleeve pipe and the 3rd sleeve pipe, and they are nested with on braid, insulating barrier and the center conductor at coaxial cable successively.In the anabolic process, first sleeve pipe is nested with in the braid periphery, and the outside turnup of braid is coated on the outer surface of first sleeve pipe, and second casing pipe sleeve places the periphery of insulating barrier exposed part, plays the uniform properties impedance.

Compared with prior art, advantage of the present utility model is: the utility model cable connector need not to divest separately the insulating barrier that is positioned at coax cable center conductor and braided wire interlayer, in the wire stripping process, can not damage very thin center conductor yet, and can improve wire stripping efficient and keep good electric property.In addition, the length of connector body is longer than cable connector commonly used, makes the assembly that cooperates with it away from circuit part like this, reduces the effect of EMI, and connector body is provided with and other left hand thread of right-handed thread phase region commonly used, can prevent to misplug with this.
