Therefore, each branch breaker 3 can be attached by hooking the locking protrusion 32 to the hooking piece 30 of the elastic hooking member 27 using the elasticity while hooking the receiving recess 33 on the hooking portion 14. When the breaker 3 is removed from the elastic hooking member 27, the end 38a is pushed by a driver or the like so that the hooking piece 30 is removed from the locking projection 32.
[0018]
The lid 6 is attached to the opening surface of the box 5 and is configured to be detachable. The lid 6 is formed with through holes 36 at positions on the conductive bars 2 a to 2 c and the branch breaker 3. The through hole 36 is formed in the auxiliary plate 54 that constitutes a part of the lid body that is mounted by the locking claw 53 inside the opening 6 a formed in the lid body 6. 55 is a through hole for the main breaker 1. The upper surface of each branch breaker 3 is formed substantially flush with the surface of the lid 6, and a slide groove 39 described later projects from the upper surface of the branch breaker 3. A cover 56 is rotatably connected to the lid 6 by a shaft 34 at one side edge of the opening 6a so as to close the breakers 1 and 3 and the insulating cover 4 so as to be opened and closed.
[0019]
The insulating cover 4 is provided on the box 5 and has a load name display unit 37 that covers the conductive bars 2a to 2c and displays the load name of each branch breaker 3 on the surface. The load name display unit 37 is a through hole 36. It faces. The load name display unit 37 includes a card 38 that displays a load name, and includes a slide groove 39 that slides the card 38 along the surface of the lid 6 at a position protruding from the surface of the lid 6. Thereby, even if the cover 6 is removed from the box 5, the load name display portion 37 is in the insulating cover 4 in the box 5, so that the lid 6 is opened or removed and each load is connected to each branch breaker 3. When performing the operation, it is possible to easily determine which load corresponds to the breaker, and the workability is improved. Further, the card 38 can be slidably attached / detached from the slide groove 39 without opening or removing the lid 6, thereby facilitating the work of attaching / detaching the card 38.
[0020]
The sliding direction of the card 38 is the extending direction of the conductive bars 2a to 2c, so that the branch breaker 3 does not get in the way when the card 38 is slidably attached and detached, and the work of attaching and detaching the card 38 is facilitated. .
[0021]
In the embodiment, the load name display unit 37 is a card holder that has a slide groove 39 and stores a card 38. This card holder is formed of a flat plate, and side walls 40 are formed on both sides, and the front end 40a is bent inward to form a slide groove 39 on the inside. Convex portions 41 that are concave are formed, and stepped portions 42 are formed on both sides thereof. The card 38 is composed of a display portion 43 and a transparent material 44 that covers the display portion 43, the center of which is placed on the convex portion 41, and both sides are engaged with the slide grooves 39 of the side wall 40. Further, the attachment portion 45 extends outward from both ends of the card holder, and attachment holes 46 are formed in the attachment portion 45.
[0022]
The insulating cover 4 includes a load name display portion 37 formed by a card holder , and a pair of cover members 47 that are detachably attached thereto and are respectively attached at positions corresponding to the branch breakers 3 at both ends. These cover members 47 are substantially inverted U-shaped, and are provided with protrusions 48 that are detachably locked to the mounting holes 46 inside, and elastic locking claws 49 at both ends. Accordingly, the card holder is attached between the pair of cover members 47, so that even if the number of branch breakers 3 increases, the insulating cover 4 can be handled by using the common cover member 47. Is easy to manufacture. Corresponding to the locking claw 49, the fixing base 8 is provided with a locking receiving portion 50 for elastically locking the locking claw 49, whereby the cover member 47 is locked to the fixing base 8. In this case, the card holder of the insulating cover 4 is disposed on the upper surface of the conductive bar 2c, the elastic hooking member 27 is disposed in the recess on the back side of the convex portion 41, and the stepped portion 42 is a locking projection as shown in FIG. It is arranged so as to come into contact with the upper surface of the hooking piece 30 for locking 32. Therefore, if the insulating cover 4 is provided, the elastic hooking member 27 is not deformed, and it is possible to prevent the locking protrusion 32 from being detached from the elastic hooking member 27.
