動するように位置されることになる。 Since the present invention is constructed as described above, the movable contact piece 12 of the coil spring is connected to the lower part of the coil part 21 and the terminal leg 1 in the low step groove 23 recessed around the pin part 22.
0, the terminal leg 10 is fitted to the outside of the device, and the coil part 21 is fitted to the pin part 22.
is installed in the upper opening of the plug insertion hole 4 in the form of a stepped protrusion, and the U-shaped ground terminal 17 is inserted in the slit 8 from the rear wall 3 side toward the front, facing both sides. By simply inserting both sides of the flat plate part 13 into the pocket grooves 7, 7' of the terminal 17, the locking protrusion 15 on one side of the flat plate part 13 of the terminal 17 locks into the locking window hole 9. , the terminal leg 16 bent downward
By contacting the rear wall 3, the terminal 17 communicates with the lower part of the plug insertion hole 4 and is securely fitted and fixed.
4' is positioned so as to open and spring within each pocket groove 7, 7' in a state in which the inner portion of the front end protrudes from inside the pocket grooves 7, 7' on both sides of the slit 8 into the insertion hole 4. That will happen.

孔4の上下個所で確実なプラグ接触となる。 As a result, in the case body 6, the U-shaped ground terminal 17 is fitted into the plug insertion hole 4 which forms a deep groove with respect to the shallow step cavity 5, and the U-shaped ground terminal 17 is fitted into the cavity 5.
Therefore, the plug abutting portion 11 of the movable contact piece 12 is protruded into the upper opening of the insertion hole 4 and is disposed in a stepped manner in an upper overlapping manner. Since the contact portions of the movable and grounding members that come into contact with the springs are arranged in a vertically different manner, the space for the arrangement mechanism is reduced accordingly, and as a result, the case body 6 can be made more compact. Then, the space 5 of the movable contact piece 12
Not only is it easy to install the ground terminal 17 inside the slot 8, but also the ground terminal 17 can be installed by simply press-fitting it into the slit 8, so the mechanism is simple and the assembly work efficiency is very high. By drilling the plug insertion hole 4 that communicates with the slit 8 and configuring the cover, it can be easily manufactured at low cost and in an ultra-small size. Therefore, when a laminated insertion plug P with electrode layers 20 on top and bottom is inserted into the insertion hole 4 from its front entrance, the plug P is inserted into the insertion hole 4 through the pocket grooves 7 and 7' of the slit 8. The lower electrode portion touches and enters between the fork-like legs 14, 14' of the lower U-shaped ground terminal 17 protruding into the hole 4, and pushes the legs 14, 14' at the concave tip. Since it is spread out, the tips of the leg pieces 14, 14' at the lower end come into pressure contact with the lower electrode part with a spring, and the upper movable contact piece 12 whose upper electrode part protrudes into the insertion hole 4 The plug abutting portion 11 of the plug is pressed to make pressure contact.
Both the movable contact piece 12 and the ground terminal 17 make reliable plug contact at the upper and lower portions of the insertion hole 4.

る。 Therefore, the spring legs of the fork-like legs 14, 14' of the flat ground terminal 17 are opened by the plug.
As the leg pieces 14, 14' are fitted into the pocket grooves 7, 7' and guided, the leg pieces 14, 14' are not bent or damaged at all, and therefore the legs of the flat leg can be opened easily. The spring force is constant, strong and durable, and together with the spring contact between the legs, there are no accidents of poor contact with the plug, ensuring reliable and stable contact performance during long-term use. The movable contact piece 12 and the ground terminal 1 are connected to the insertion hole 4.
Due to the overlapping arrangement configuration of the upper and lower steps with respect to 7, it is possible to use a laminated plug in which the electrode layers 20 are laminated on top and bottom.
The laminated plug has a very simple structure and can easily be manufactured into an ultra-small plug, which is very economically advantageous. This makes it very convenient to arrange multiple U-shaped ground terminals 17 in different levels, and the laminated multi-pole plug can be made very small by simply sandwiching the insulating layer 19 with electrodes. Since it can be manufactured in a small size, the target plug used can be made ultra-small and economical, and in conjunction with this, as mentioned above, the ultra-small body and high assembly efficiency make it economical and have excellent contact performance. It has the advantage of being able to mass-produce stable ultra-compact jacks.
