Description of the Invention: [Technical Field] The present invention relates to a connector for connecting a coaxial cable to an end connector. [Prior Art] The existing connector is used to connect a coaxial cable to the end connector for use in cable signal transmission and data transmission lines, etc., and the coaxial cable includes a core conductor, - covering the center, and the conductor. The insulator, the box covering the outside of the insulator, at least one layer of the braided conductor covering the outside of the box, and one covering the outer sheath of the braided conductor. Since the specifications of the coaxial cable can be divided into 阢6, 阢7, RG11, RG59, etc., and the size of each type of coaxial cable needs to be installed in the corresponding connector, this connection method will cause the technician to install the coaxial cable. The connector has a line rate that does not match the line, and the manufacturer has to manufacture connectors of various specifications for use with a variety of coaxial cables, resulting in increased manufacturing costs. The above-mentioned reference to the coaxial cable is mounted on the connector, which is inherently limited. For example, whether the specification of Wei and the connector is a very difficult technique is to look at the experience of the technician. At this stage, it is necessary to provide a connector structure suitable for: a specification of an electric gauge and to eliminate the possibility of installation errors. When the coaxial electrical connector is installed with a coaxial electric cymbal, the end of the electrical environment is first processed & operative to be engaged with the connector. . The connector is then applied to the end of the coaxial cable in a human 1 manner until the outer sheath of the coaxial cable and the braided conductor are isolated from the insulator 5 I33S422 ·· . The same car i cable continues to be pushed into the connector by hand until the desired insertion depth is obtained. Finally, a compressive force is applied to the connector by a hex crimping tool to force the connector to tightly bond with the coaxial electric. Due to various variations in the size of the coaxial cable, three different sizes of hexagonal crimping tools are required to ensure sufficient compressive force can be applied to the connector, thus requiring additional cost and multiple crimping tools and carrying additional The inconvenience of the tool must be considered.
