DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to FIGS. It should be noted that components having the same functions as those of the conventional example shown in FIGS.

The outer case 9 of the plug 3 is a case body 9
a and a lid 9c integrally connected to the case body 9a by a connecting portion 9b and formed by resin molding. The case body 9a is connected with a first connection terminal 7 to which the central conductor 2c of the coaxial cable 3 is connected, a second connection terminal 4 to which the outer conductor 2a of the coaxial cable 3 is connected, and a 300 ohm balanced antenna cable. The connection terminal 10 is installed.

As shown in FIGS. 4 and 5, the lid 9c has a claw 12a which is elastically deformed and engages with the stepped portion 11 of the case body 9a when it is bent at the connecting portion 9b to cover the case body 9a.
12b is formed. An annular outer electrode portion 14 is attached to the second connection terminal 4 so as to surround the center electrode portion 13 of the first connection terminal 7 drawn out from the case body 9a.

Although not entirely visible in FIG. 1 hidden under the second connection terminal 4, the connection terminal 10 for the 300 ohm balanced antenna cable and the first and second connection terminals 7 and 4 are not shown. A matching box 15 is installed between the
Reference numerals a, 15b, 15c and 15d are matching windings of the matching device.

The second connecting terminal 4 is integrally formed with engaging portions 16a, 16b, 16c and 16d as shown in detail in FIGS. At both ends 4a, 4b of the opening 5 of the second connection terminal 4 having a substantially U-shaped cross section in the radial direction of the coaxial cable 3, both ends of the coaxial cable 3 in the length direction [the direction of arrow A] are lengthwise. Engagement portions 16a and 16c are integrally formed on the inlet side B, and engagement portions 16b and 16d are integrally formed on the outlet side C. Specifically, the engaging portions 16a to 16a are formed by sheet metal processing in which a piece integrally formed with the second connection terminal 4 is bent outward.
16d is formed integrally with the second connection terminal 4.

In this way, the engaging portion 16a is attached to the second connecting terminal 4.
The coaxial cable 2 is connected to the plug 3 formed with ˜16d as follows. Since the connection between the central conductor 2c of the coaxial cable 3 and the first connection terminal 7 of the plug 3 is the same as the conventional one, here, the second connection terminal 4 holds the coaxial cable 2 and the outer conductor 2a and 2 connection terminals 4
The electrical connection with and will be described. As shown in FIG. 3, the terminal-treated coaxial cable 3 is placed on the second connection terminal 4, and one coin 17a is placed in the engaging portions 16a, 16b located on one side with the coaxial cable 3 as the center. The coin 17b is placed and engaged, and the other coin 17b is placed and engaged with the engaging portions 16c and 16d located on the other side. Next, coin 17a,
17b is picked up with a finger and forces F ₁ and F ₂ are applied as indicated by the arrows so that both ends 4a and 4b of the opening 5 of the second connection terminal 4 are deformed to imaginary line positions so as to approach each other. The coaxial cable 2 is sandwiched between the connection terminals 4 of 2 to complete the connection.

When the connection is completed, the coins 17a and 17b are removed, the lid 9c is closed, and the work is completed. In this state, the shield cover 18 attached to the inside of the lid 9c covers the upper portion of the first connecting terminal 7 and
The tongue pieces 18a and 18b of 18 are the tongue pieces 4c and 4 of the second connection terminal 7.
The necessary shield effect is satisfied by contacting d.

In this way, two coins 17 that are familiar to us
A and 17b can be used to make a correct connection without using pliers. In the above embodiment, the engaging portions 16a to 16d are formed on the inlet side B of the second connecting terminal 4 by sheet metal processing in which a piece integrally formed with the second connecting terminal 4 is bent outward.
Since it is provided on the outlet side C, the coin 17a can be placed and supported stably on the engaging portions 16a and 16b, and the coin 17b can be placed on the engaging portions 16c and 16d. It can be stably supported and can be processed in a stable state.

[0016]

As described above, according to the present invention, in the coaxial cable plug for sandwiching the coaxial cable by deforming both ends of the opening of the second connection terminal so as to approach each other, the second connection terminal Since the engaging portion with which the coin can be engaged is formed integrally, the terminal-treated coaxial cable is placed on the second connecting terminal, and the coin is engaged with the engaging portion integrally formed with the second connecting terminal. By engaging and gripping, the second connection terminal can be deformed and correct connection processing can be performed without using a tool such as pliers.
