Description

  The present invention relates to a coaxial connector, and more particularly to an L-shaped coaxial connector.

  Increasing demand for communications and improving industrial technology have spread the use of communications products. A coaxial connector is an indispensable part of communication products, and is connected to a coaxial cable to transmit a high-frequency signal. Since the volume of the coaxial connector is extremely small, it is not easy to assemble it manually. Coaxial connectors must therefore be assembled by machine.

  A conventional coaxial connector, for example, “L-type coaxial connector and terminal therefor” disclosed in Patent Document 1 published on Feb. 16, 2001, is an above-described coaxial including an outer conductor, an insulator, and a terminal. It is a connector. The outer conductor has a cylindrical portion, an outer lid portion, and an enclosing portion. The insulator has a main body and a shoulder. When assembling the coaxial connector, the central conductor of the coaxial cable is first contact-connected to the terminal, and then the terminal is positioned in the main body of the insulator, and then the insulator is installed in the outer conductor. Of these, the main body portion and the shoulder portion are accommodated in the cylindrical portion and the surrounding portion, and finally, the bent outer lid portion covers the insulator and fixes the coaxial cable.

  The conventional coaxial connector does not have a corresponding positioning structure between the insulator and the external conductor. Accordingly, since the insulator is accurately positioned in the outer conductor by a machine having extremely high accuracy, the production cost is greatly increased. If the higher-order insulator and the outer conductor are assembled by a machine with relatively low accuracy, the insulator cannot be positioned in the outer conductor due to factors such as easily deviating or rotating.

  Therefore, as can be seen from the above, the conventional coaxial connector has obvious disadvantages and disadvantages in practice and must be improved.

Therefore, in view of the above drawbacks, the inventor devoted himself to research on the application of science in order to improve it, and finally proposes the present invention capable of improving the above defects reasonably and effectively. became.

  The coaxial connector of the present invention is assembled and completed by the following steps. First, the central cable 40 of the coaxial cable 4 is passed from the positioning groove 123 of the conductive terminal 1 to the stopper portion 11 of the conductive terminal 1 and soldered at the connection portion 10 of the conductive terminal 1. Thus, the conductive terminal 1 is connected to the central conductor 40 of the coaxial cable 4.
