A groove is formed between the operation piece 31 and the fulcrum projection 33.

The cover 12 is formed with a plug blade insertion hole 17 into which a plug blade is inserted at a position corresponding to the blade receiving part 21 of the blade receiving spring 2, and a recess is formed at a position corresponding to the operating piece 31 of the release 1a30. 18 is formed, and an exposure window 19 is formed at the bottom of the recess 18 to expose the operation piece 31 to the front side of the cover 12. Furthermore, notches 20 are formed at both ends of the cover 12 in the longitudinal direction at positions corresponding to the body first grooves 15. As shown in FIG. 2, the front surface of the piece 31 is recessed from the front surface of the cover 12. Therefore, since the release button 30 is recessed from the front surface of the cover 12, the release button 30 may be accidentally pressed. The pressing protrusion 32 of the release button 30 comes into contact with the lock piece 24 of the lock spring 23. Therefore, the operation piece 31 of release #30
When the front surface of the operating surface is pressed with a finger, the release button 30 rotates around the support point projection 33 and presses the locking piece 24 of the locking spring 23. As a result, the lock piece 24 is held between the terminal frame 22 of the blade holder spring 2, and the blade holder spring 2
This allows you to easily remove external wires connected to the That is, the external electric wire can be removed simply by manually pressing the release button 30 while the container body 1 is attached to a mounting surface such as a wall surface.

(Embodiment 2) In this embodiment, the cover 12 is moved between the operation position where the pressing protrusion 32 of the release #30 can come into contact with the lock piece 24 of the lock spring 23 and the standby position where it cannot come into contact with the lock piece 24. An example is shown in which it is slidably arranged along the front.

As shown in FIG. 3, the locking recess 34 formed in the inner peripheral surface of the cover 12 is formed wider than the fulcrum projection 33 in the longitudinal direction of the cover 12. As shown in FIG. Therefore, lock @30
The cover 12 can be slid freely in the longitudinal direction within a range where there is play between the fulcrum projection 33 and the locking recess 34. In this sliding range, the release button 30 is
When the release button 30 is located at the operating position near the center of the cover 12, the pressing protrusion 32 comes into contact with the lock piece 24 of the lock spring 23, and when the release button 30 is located at the standby position near the outside of the cover 12, The pressing protrusion 32 is set so as to be separated from the locking piece 24 of the locking spring 23. Further, the release button 30 is made of a flexible material such as thermoplastic synthetic resin, and is integrally formed with a spring piece 36 that serves as a return spring that urges the release button 30 to the standby position. In other words, release button 3
When no external force is applied to the release button 30, the release button 30 is pressed by the spring piece 36 and is located at the standby position. A step 37 is formed on the inner peripheral edge of the exposure hole 19 of the cover 12, and the operation piece 31 is locked to the step 37 when the release button 30 is in the standby position. There is. Therefore, in order to press the locking piece 24 with the release button 30, it is first necessary to move the release button 30 to the operating position against the spring force of the spring piece 36, which may cause the user to accidentally press the locking button 30. This has the advantage that accidents such as external electric wires falling off due to this can be prevented and safety is high.
