[Prior art]

 In general, in a cable television system, a wireless television system, and a joint antenna television system, one main line is connected to a distributor, and each of the main lines is output to a sub-main line from the distributor and connected to a customer end. The transmitted signal is received. The main trunk connects a coaxial connector to the end of a coaxial cable, and is attached to the distributor by the coaxial connector. FIG. 1 shows a coaxial connector currently used. The main function of this coaxial connector is to transmit an electric signal through a good connection between the coaxial shield and the connector body. The coaxial connector 100 includes one connector main body 101, a first joint sleeve 102 is coupled to one end of the connector main body 101, and a second joint sleeve 103 is coupled to one end of the first joint sleeve 102. . The connector main body 101 has one annular shaft ring 104, one holding means 105 is coaxially arranged in the shaft ring 104, and one seal body 106 is provided between the inner surface of the main body 101 and the end of the shaft ring 104. It is located at One fixing means 107 is coaxially arranged in the second joining sleeve 103, and one contact means 108 is coaxially arranged in the fixing means 107. One columnar means 116 is mutually adjacent to the clamping means 105.

As shown in FIG. 2, the holding means 105 is a foil-shaped annular body, which includes a single tubular body 110 and a plurality of protruding engaging portions 111 formed at both end portions thereof. The engaging portion 111 can be engaged with the protruding wall 119 of the shaft ring 104, and the holding means 105 is fixed in the shaft ring 104. As shown in FIG. 3, one contact means 108 is coaxially disposed within the second joining sleeve 103, and one end of the contact means 108 is a contact end 112 and is combined with the distributor to form an electrical connection. The other end is a holding end 113, the holding end 113 has a female screw 114, and the support end 113 has a plurality of grooves 115.

Therefore, before the coaxial connector 100 and the cable 200 are combined, first, the free end of the cable is peeled and prepared. As a result, the aluminum shield 116 and the core wire 117 are exposed from the outer cover 118. Second, the prepared cable 200 is inserted into the connector main body 101. Third, the connector main body 101 and the first joining sleeve 102 are mutually connected and integrated. The inside of the holding means 105 is covered with the outside of the aluminum shielding body 116 and held tight. Fourth, the connector body 101 into which the cable 200 has been inserted and the second joining sleeve 102 are joined to be integrated. Finally, the core wire 117 of the cable is inserted into the female screw 114 of the contact means 108 by coupling. With the above combination, the core wire 117 is forcibly fixed to the contact means 108 to form an electrical connection.

[0005] As can be seen from the above-mentioned combination process, the combination process of the conventional coaxial connector is considerably complicated, and the disadvantage is that the work efficiency of the operator is reduced. In addition, the inside of the holding means 105 is tightly covered with the outside of the aluminum shield 116 (that is, rigid-to-rigid contact), that is, due to environmental factors or other factors, such as thermal expansion and contraction of air, and wind. Due to vibration or the fatigue of the material itself, the clamping force between the clamping means 105 and the aluminum shielding pair 116 is loosened. As a result, good coupling between the coaxial shielding pair and the connector body cannot be maintained, and the electric signal transmission performance is reduced. The impact was particularly severe in the case of digital transmission. In order to prevent such a situation from occurring, the worker re-tightens the connector body 101 and the first joining sleeve 102 every year, but such a solution requires additional cost and time, and therefore needs to be considered. Was.

[0006] As described above, the well-known technology needs to be improved, and there has been a demand for providing a coaxial connector having an even higher clamping force.
