External diameter.
As the most preferably, described insulator is for being molded.
As the most preferably, described column insulator both ends of the surface beat the blind hole that quantity is identical respectively.
As the most preferably, the blind hole in described both ends of the surface is spaced apart.
As the most preferably, the degree of depth of the blind hole in described both ends of the surface is the most identical.
As the most preferably, the quantity of the blind hole in described both ends of the surface is 3.
The embodiment of the present invention at least has the advantages that
1, the position avoiding deep hole in the middle part of the center conductor face of cylinder arranges a substantially rectangular groove in cross section, has electrically
Compensating action, can make standing wave signal reduce, and improves signal of telecommunication transmission quality.
2, the center conductor face of cylinder is provided with micro-shallow groove, and center conductor face of cylinder rear end face is provided with agnail.Micro-shallow
Groove and agnail two point stationary positioned, have the effect of firm connection, and be capable of preferably realizing electrical compensation with slot fit.
3, a convex edge is set in center conductor rear end, there is location, realize electric with outer conductor mating reaction simultaneously
The compensation of electrical property, and have the effect of stable connection.
4, center conductor deep hole arrival end inwall is processed as a point flap, remains contraction when processing and install, and inserts cable
During center conductor softened.Close contact by the elastic reinforcement connector center conductor of lobe Yu cable center conductor.
5, connector center conductor deep hole bottom diameter of bore is processed into the external diameter more than cable center conductor.Protect during installation
The end face of card cable center conductor does not contacts with connector center conductor deep hole bottom.During vibration, contact surface keeps constant, deep hole
Bottom does not contacts with cable center conductor, it is ensured that stablizing of signal of communication.
6, insulator is for being molded, and makes processing and installation the most more hold on the premise of not affecting communication signal transmissions
Easily, and make insulator more firm with the connection of connector center conductor, and cost is lower, turning can also be used simultaneously
The method of machining makes.
7, beating blind hole on insulator, blind hole is spaced apart and the degree of depth is identical.Before and after making insulator be not required to when installing distinguish, peace
Dress is convenient；Insulator is symmetrical, and communication signal transmissions is effective.
Owing to not affecting prior art standard, therefore the cable connector of the embodiment of the present invention can and prior art
In various constructed standard female joint connect, there is good versatility.
