When connecting the coaxial cable 31 to the base box 1 using the connector with the above configuration, the coaxial cable 3
Peel off the tip of 1 in a well-known manner. Note that 32 represents an outer conductor, 33 represents an inner insulator, and 34 represents a center conductor. Next, insert the tip of the coaxial cable 31 into the insertion hole 13, and connect the outer conductor 32 to the stopper 14.
, and the center conductor 34 is passed through the insertion hole 18 so that the tip thereof protrudes beyond the main body. Next, the seventh
As shown in the figure, the stopper 14 is deformed using a tool 36 such as pliers, and the outer conductor 32 is fastened by the stopper 14. Next, the center conductor 34 protruding from the insertion hole 18 is bent along the groove 19, and its tip is attached to the attachment part 20. Next, the insert 11 is inserted into the recess 3. In this case, if the insert 11 is pushed toward the deep part of the recess 3, the guide surface 27
a, 28a causes the arm piece 25 to deform as shown by the broken line in FIG. , and the engaged state shown in FIG. 4 is achieved. In this state, as is clear from FIG. 3, the center conductor 34 is connected to the connector 4, and the contactor 17 is in contact with the connector 6, thereby establishing electrical continuity between them. Next, if necessary, the waterproof cap 35 is placed over the fitting portion 21 with its tip abutting the stopper 22, as shown in FIGS. 3 and 4. In this state, the distance G' between the inner surface of the arm piece 25 and the outer surface of the waterproof cap 35 is smaller than the dimension sufficient to disengage the engagers 27 and 28, so the knob 29 may be operated by mistake. Even if the arm piece 25 bends toward the main body 12, an accident in which the engaging elements 27 and 28 become disengaged is prevented.

Next, when you want to remove the insert 11 from the recess,
The waterproof cap 35 is removed, and then the knob 29 is operated to bend the arm pieces 25 toward the main body 12 against their elasticity. As a result, the engager 27 becomes the engager 28
Since the insert 11 can be removed from the recess 3, it can be removed from the recess 3.

Next, FIGS. 8 to 10 show other examples of the structure of the connector for the center conductor. The connector for the center conductor can be configured in various shapes as shown in these figures.

It should be noted that the same reference numerals as those in the previous figure are appended with an alphanumeric letter "e" for parts that are functionally the same or equivalent to those in the previous figure, and redundant explanations are omitted.

(Also, in the following figure, the same concept is used, and the redundant explanation is omitted by adding an alphanumeric letter f.) Next, Fig. 11 shows another example of a connector for an external conductor. This shows an example in which the portion 6f is formed into a shape that bulges inside the recessed portion 3f.

(Effect of the invention) As described above, in the present invention, when it is desired to connect a coaxial cable, the tip of the stripped coaxial cable is inserted into the main body 12 of the plug 11 as described above, and the outer conductor 32 is connected. The outer conductor 32 and the center conductor 34 of the coaxial cable 31 are attached to the stopper 14 and the center conductor 34 is attached to the attachment part 20, and in this state, the insert 11 is inserted into the recess 3 of the base box 1. can be connected to connectors 6 and 4 for the outer conductor and the center conductor provided in the base box 1, respectively.

Furthermore, even if the base box 1 and the plug 11 are integrated as described above, when it is desired to separate the coaxial cable from the base box 1 for repair or inspection reasons,
Since there is a gap G between each arm piece 25 and the main body 12, by pinching the knobs 29, 29 attached to each arm piece 25 and bringing them closer together, the engagement elements on both sides can be almost closed. You can easily remove the base box 1 by removing it at the same time.
There is an operational feature that allows the insert to be removed from the

Furthermore, the above-mentioned G also has the secondary effect of not interfering with the attachment of the waterproof cap 35 to the main body 12 if necessary.
