われる。 Next, the procedure for assembling the above configuration at the manufacturer will be explained. First, the external conductor 16 is placed on the base 1 with the holding frame 2 passing through the through hole 17 thereof. Next, the outer cylinder body 23 is inserted into the holding cylinder 12, the retaining claws 25 are made to protrude from the retaining hole 14, and the retaining claws 25 are bent slightly outward as shown in FIG. 6, and soldered to the connecting piece 18. Connect by any means. Next, the center conductor 30, to which screws 34 and nuts 35 have been attached in advance, is fixed to the base 1. Its attachment is
Move the center conductor 30 in the direction of arrow A from the position shown by the phantom line in FIG. 4, and insert the center pin 40 into the through hole 1.
3 and the through hole on the side of the recess 3 in the outer cylinder 23 and inserted into the inside of the outer cylinder 23, and with the fitting side plates 36, 36 facing the opening of the recess 3, as shown by the solid line in FIG. state. Next, the seat plate 32 is strongly pressed in the direction of arrow B, for example, with the thumb, and the fitting side plate 36 is pushed deep into the recess 3. Then, the fitting side plate 36 is pushed into the recess 3 while tilting in the direction of arrow C in FIG. 4, resulting in the state shown in FIGS. 2 and 3. In the above case, as the protrusion 39 moves downward along the guide slope 5 as shown in FIG. In this state, the protrusion 39 passes through the engaging portion 6 and reaches the recessed portion 7 . When the protrusion 39 reaches the missing part 7, the side plate 36 or the side wall 4 returns to its original state due to its elasticity, and the third
As shown in the figure, the protrusion 39 is engaged with the engaging portion 6. Therefore, in this state, the center conductor 30 moves forward with respect to the base 1 because the front edge 37 comes into contact with the front wall 8, and the center conductor 30 moves backward with respect to the base 1 because the rear edge 38 comes into contact with the front wall 8. By contacting the rear wall 9, the side plate 3 can move laterally.
6 comes into contact with the side wall 4, the protrusion 39 attempts to slip out upwards, and the protrusion 39 engages with the engaging portion 6, and the seat plate 32 attempts to sink downward. are prevented by contacting the upper surface of the front wall 8 and by the lower end of the side plate 36 contacting the bottom surface of the recess 3, respectively, and the center conductor 30 is
It will be securely fixed against. Further, in this state, the center pin 40 is located at the axial center position of the outer cylinder body 23. Next, the lid body 41 is attached to the base body 1 and shipped with it fixed with screws 42.

る。 Next, the user removes the screws 42, opens the lid 41, and connects the stripped coaxial cable 43 as shown in FIG. 6, as is well known. That is, the crimping piece 21 is crimped onto the outer sheath 44, and the core wire 45 is inserted between the seat plate 32 and the nut 35 through the cutout 9a of the rear wall 9, and sandwiched therebetween. After that, the lid 41 is fixed to the base 1 again using the screws 42.
Next, the outer cylindrical body 23 is placed over the outer conductor of a well-known connector seat from the opening at its tip, and the center pin 4
0 into the center conductor of the plug seat to make the connection to the plug seat. This makes it possible to establish an electrical connection between the coaxial cable and the connector seat.

In order to connect the core wire 45 of the coaxial cable 43, the seat plate 3 for fixing the core wire is formed to be strong
2 is pressed down with a finger, the force is applied from the core wire fixing seat plate 32 to the fitting side plates 36, 36, which are bent down on both sides, so that the seat plate 32 and the side plate 36 are connected to each other. This has the effect of being able to reliably push in the center pin 40 by applying a large push-down force without causing the center pin 40 to bend greatly. This has the effect of preventing the center pin 40 from being bent in advance and allowing the center pin 40 to be correctly positioned on the axis of the outer cylindrical body 23.
