Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coaxial connector,
In particular, it relates to a coaxial connector for fixing a center contact.

[0002]

2. Description of the Related Art In a conventional coaxial connector, as shown in FIG.
5 is soldered or crimped and fixed, penetrates through the dielectric insulator 16 of the connector, and the coaxial cable jacket 17 is crimped and fixed to the ferrule 19 mechanically connected to the connector body 18. The outer conductor 20 of the coaxial cable 13 is held by the ferrule 19 so as to make electrical contact with the connector body 18.

[0003]

The conventional coaxial connector has a structure in which only the coaxial cable jacket is fixed to the connector main body or the one integrated with the main body. dielectric insulator and the cover fabric and the outer conductor and the center contact of the resulting coaxial connctor lag behind the protrusion or including the conductive, there issues that depression is.

[0004]

The coaxial connector of the present invention suppresses the movement in the opposite direction of the mating surface pressed into the dielectric insulator of the entire inner shell for soldering and fixing the center conductor of the coaxial cable. Central contact with a brim,
The inner shell and the rear shell that fix the coaxial cable jacket are provided.The inner shell and the rear shell are combined with the connector body to form an integral body. Be transformed into

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings.

FIG. 1 is an exploded half sectional view of a coaxial connector having a fixed center conductor portion according to an embodiment of the present invention. In the figure, a dielectric insulator 2 into which a center contact 1 with a collar for preventing depression is press-fitted from a mating surface of a connector is caulked and fixed to a front portion of an inner shell 3. The coaxial cable 4 having been subjected to terminal treatment from the coaxial cable insertion side of the inner shell 3 is inserted until the dielectric insulator 5 and the internal stopper 11 of the inner shell 3 are completely abutted. 6 and solder.

After assembling the inner shell 3 into the connector body 8 and tightening the rear shell 9, the cushioning material 1 is
The outer conductor 7 of the jacket 12 of the coaxial cable 4 is connected and fixed to the outer surface of the inner shell 3 by soldering via the wire 0.

[0008]

As described above, according to the present invention, the center conductor of the coaxial cable, the center contact of the connector to be soldered and fixed, and the center conductor of the coaxial cable are covered with each other and the dielectric insulator having a large frictional force is mutually connected. Since the coaxial cable is fixed, the problem that the center contact of the coaxial connector is protruded or depressed due to bending and extension of the coaxial cable can be avoided.

Claims (1)

(57) [Claims] 1. A center connector having a flange press-fitted into a dielectric insulator at a front portion of an inner shell for soldering and fixing a center conductor of a coaxial cable, and having a collar for restricting movement in a reverse direction of the mating surface. It has a stopper inside the inner shell that restricts the dielectric insulator from moving in the forward direction of the mating surface, and a rear shell that fixes the coaxial cable jacket. Coaxial connector characterized by the above-mentioned.
