A short piece 5a and a long piece 5b are attached from both ends of the U-shaped portion 6 of the sound spring 5.
The short piece 5a is located on the top surface of the terminal frame 2 on the side of the terminal piece 2a, and the long piece 5b extends in the opposite direction to the short piece 5a and is located on the top surface of the terminal frame 2. . The long piece 5b has an upward biasing force, and its tip 5C is attached to the base 1.
It is secured to the lower surface of a stepped portion 7 formed on the ceiling surface inside.

Note that this stepped portion 7 may be formed into four parts integrally formed with the base 1 which is a molded product, and metal may be placed in the recessed portion. The step g7 may also be formed by adding the steps.

A release button 8 is arranged above the lock spring 3, and the upper part of the release button 8 is inserted into an insertion hole 9 drilled in the base 1, so that the upper part of the release button 8 is exposed on the upper surface of the base 1. . A slit 10 into which the tip of a screwdriver is inserted is formed on the upper surface of the release button 8 made of an insulating material, and the lower part of the release button 8 is bifurcated to form a lock that presses one side of the upper part of the lock spring 3 inside the terminal frame 2. Part pressing piece 1
1 is formed. Furthermore, spring pressing pieces 12 are integrally provided to protrude from the side surface of the release button 8, respectively. Among them, the release button 8 is disposed within the base 1, and the upper surface of the spring pressing piece 12 abuts against the ceiling surface of the base 1 to restrict its positioning. Spring pressing piece 12
As will be described later, this is formed for returning the long piece 5b of the sound spring 5. An insertion hole 14 into which the electric wire 13 is inserted is bored at one end of the base 1, and a terminal piece 2a of the terminal frame 2 protrudes from the other end of the base 1. In FIG. 1, the conductor 13a indicated by the dashed line is the position where the electric wire 4Q13 is inserted.

However, before the cable #113 is inserted and connected, the
), the tip end 5c of the long piece 5b of the sound spring 5 is engaged with the stepped portion 7 of the base 1. Further, the release button 8 is attached above by the lock spring 3. Next, wire 1

When fully inserted, the tip of conductor 13n is at f53.
As shown in Figure (b), the U-shaped portion 6 of the sound spring 5 is pressed. When the U-shaped portion 6 is pressed by the conductor 13a,
The long piece 5b of the sound spring 5 retreats, and the tip 5C of the long piece 5b
comes off from the stepped portion 7, and when this tip portion 5C comes off from the stepped portion 7, it emits a tactile sound that bounces upward.

Therefore, this sound allows confirmation of complete insertion of the conductor 13a. Further, when removing the conductor 13a, proceed as follows. That is, when the release button 8 is pressed downward,
While pressing the locking spring 3 with the locking part pressing piece 11,
The spring pressing piece 12 presses down the long piece 5b of the sound spring 5, locks the tip 5C to the stepped portion 7, and returns to its original position.

FIG. 6 shows an embodiment in which the sound spring 5 and the terminal frame 2 are integrally formed. In this case, the terminal frame 2 is made of an elastic material.

Figures f57 to 9 show the tip 5 of the long piece 5b of the sound spring 5.
This shows an embodiment in which the terminal frame 2 is provided with a stepped portion 7 to which the terminal frame 2 is engaged. That is, an L-shaped step 7 protruding from the upper surface is formed at the end of the terminal frame 2, and the tip 5C of the sound spring 5 is locked to the step 7 when the conductor 13a of the electric wire 13 is not connected. This is what I did. Also, bend the short piece 5a of the sound spring 5 into an L shape, and attach the tip of the short piece 5a to the terminal frame 2.
It is designed to be inserted and locked into a hole 15 drilled in the hole 15.

The ponne pressing piece 12 of the release button 8 is formed larger than in the above case, but 8! Noh is the same. It should be noted that the other operations for planting and attaching/detaching the electric wire tQ13 are the same as in the previous embodiment, and will therefore be omitted.
