The release button 6 is made of an insulating material, and is pressed by a jig such as a driver inserted from the outside to press the lock spring 5 in a direction opposite to the pressure contact direction of the conductor, so that the conductor and the terminal board 4 come into contact with each other. Is to be released.

An insertion opening 8 for inserting a conductor of an electric wire is formed on the upper surface of the body 2 so as to correspond to the terminal board 4, and a release opening 9 for inserting a driver beside the insertion opening 8 corresponds to the release button 6. Is formed. A hole 11 for inserting the connecting piece 7 of the terminal board 4 is formed in the middle cover 10 that closes the lower surface of the opening of the body 2.
Has been drilled. Further, engaging holes 13 into which engaging protrusions 12 provided on both sides of the middle cover 10 are inserted are formed on the side portions of the body 2.

The cover 3 for closing the upper surface of the body 2 includes
The insertion opening 1 corresponds to the insertion opening 8 and the release opening 9 of the body 2.
4 and a release port 15 are formed respectively. Also, cover 2
Elastic locking pieces 20 are formed on both sides of the locking hole 19 to engage with the protrusions 18 of the body 2. Further, substantially U-shaped elastic pieces 21 are formed at the four corners of the cover 3.

The cover 3 is attached to the opening 23 of the panel 22. The cover 3 is inserted from the front surface of the panel 22, and the tip of the elastic piece 21 that has returned is the panel 22.
The cover 3 is adapted to be attached to the panel 22 by abutting on the back surface of the. Then, the body 2 having the printed circuit board 16 attached to the back side is mounted from the back side of the panel 22 and is joined.

Then, the conductor of the electric wire from the outside is inserted into the housing mounted on the panel 22 from the front side of the panel 22 through the insertion ports 14 and 8, and the conductor of the electric wire is inserted into the terminal board 4. By inserting it between the inner surface of and the lock spring 5,
The conductor is pressed by a lock spring so that the terminal plate 4 and the conductor are contacted and connected.
