As preferably, the described center conductor face of cylinder is provided with little shallow groove, and center conductor face of cylinder rear end face is provided with hangnail.

As preferably, the deep hole outer end on the described center conductor rear end face is provided with outside convex edge.

As further preferred, the deep hole arrival end inwall on the described center conductor rear end face has some grooves, makes inwall be a minute flap.

As further preferred, one section internal diameter of the close bottom of described center conductor deep hole is greater than the external diameter of cable center conductor.

As further preferred, described insulator is injection molded.

As further preferred, beat respectively the identical blind hole of quantity on the described column insulator both ends of the surface.

As further preferred, the blind hole on the described both ends of the surface is spaced apart.

As further preferred, the degree of depth of the blind hole on the described both ends of the surface is all identical.

As further preferred, the quantity of the blind hole on the described both ends of the surface is 3.

The embodiment of the invention has following beneficial effect at least:

1, the position of avoiding deep hole, center conductor face of cylinder middle part arranges the groove that a cross section is roughly rectangle, has the electrical compensation effect, and standing wave signal is reduced, and improves the electric signal transmission quality.

2, the center conductor face of cylinder is provided with little shallow groove, and center conductor face of cylinder rear end face is provided with hangnail.Little shallow groove and hangnail two point stationary positioned have the effect of firm connection, and cooperate with groove and can realize better realizing electrical compensation.

3, a convex edge is set in the center conductor rear end, has the location, realize simultaneously the compensation of electric electrical property with the outer conductor mating reaction, and the effect of stable connection is arranged.

4, center conductor deep hole arrival end inwall is processed as a minute flap, remains contraction when processing and installation, is strutted when inserting cable center's wire.By the elastic reinforcement connector center conductor of lobe and the close contact of cable center conductor.

5, connector center conductor deep hole bottom diameter of bore is processed into the external diameter greater than cable center conductor.The end face that guarantees cable center conductor during installation does not contact with the connector center conductor deep hole bottom.Contact-making surface remains unchanged during vibration, and deep hole bottom does not contact with cable center conductor, guarantees the stable of signal of communication.

6, insulator is injection molded, do not affecting under the prerequisite of signal of communication transmission so that processing and installing all is more prone to, and so that insulator is more firm with being connected of connector center conductor, and cost is lower, also can use the method for the machining of turning to make simultaneously.

7, beat blind hole on the insulator, blind hole is spaced apart and the degree of depth is identical.So that before and after insulator need not distinguish when installing, easy for installation; Insulator is symmetrical, and the signal of communication laser propagation effect is good.

Owing to not affecting the prior art standard, thus the cable connector of the embodiment of the invention can be connected the female joint of various constructed standards and connect, have good versatility.
