Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch VC for a power distribution board in which a display panel face plate is detachably attached to a base member.

The display panel face plate is attached to the base member and can be detached.In 7, for example, there is a mosaic panel type switchboard.The switchboard is formed by arranging multiple mosaic panel units vertically and horizontally. Since the power distribution pattern can be changed arbitrarily, there is a large degree of freedom in design, and it is convenient because design changes can be easily made.

In a conventional mosaic panel unit, the switch is provided in a built-in socket into which an indicator light can also be attached, and its structure is as shown in FIGS. 1 and 2.

That is, one unit (A) consists of a base part (B) and a cover part 0 that is detachably attached to the open end of this pace part a3), and the pace part (B) is partitioned by a partition wall. A case with holes drilled vertically and horizontally in the bottom (B1)
The socket (B2) fixed to the bottom of this case (B1)
), and the socket (B2) has a bamboo shoot spring (a movable contact supported by the brain (B4) and a movable contact (B4) that can come into contact with the bottom end of the movable contact (B4)) corresponding to the through hole. A contact mechanism section consisting of a fixed contact piece CB5) is formed, and an indicator light (
B6) is held so that it can conduct electricity by bringing the movable contact (B4) and fixed contact piece (B7) into contact. 1. Bright part (C21, (C2)) Card insertion part (0)
, a push button (C4), etc. are provided, and the push button (C4) pushes the movable contact (B4) via the actuating rod (C5I).
b is enabled, and when the pushbutton (C4) is pressed, the movable contact (B4) and the polished contact piece (B5) use a switch mechanism. This is a device for bundling electric wires connected to the section.

However, in the case of a switch for a distribution or electrical panel formed of such conventional contact mechanism sections, a large number of contact mechanism sections are fixedly provided, so contact mechanisms other than those used are unnecessary. However, since the expensive contact mechanism part becomes idle, it is expensive and it is not possible to reduce the cost. In order to provide the contact mechanism only at key points, the socket (B2) would have to be removed, which would have been impossible due to assembly costs.

The present invention focuses on these conventional problems and makes it possible to install the switch independently without going through the socket ζB2 (because it is a book written with -), and moreover, it is a rotary operation switch that allows multi-stage operation. The purpose is to resolve the 1st amount point of the superior officer.

In order to achieve this purpose, in the present invention, a switch is attached to the base member.2. ,? 1. The switch body has a force attached to the display face plate, and the switch body has an operating section that can be attached to the switch body. A retaining part that can be engaged with and detached from the operating part and a cam part having a circumferentially disposed cam surface that undulates in the radial direction ζC are provided on the head of the rotary operating part, and the bearing A brake element that slides elastically on the cam surface is fixedly attached to the cam surface so that it operates smoothly as a multi-stage rotary operation switch and can be installed independently.

), and the lower end of the operation shaft (71) is provided with a secured part (73) split into two parts that mesh with the engaging part (41) of the switch body (4), A knob (74) is attached to the upper end through serrations (71a), and a positioning pin (74a) is pivotally supported on the knob (74) by being heated by an urging pin (74b), and the positioning pin (74, A switch display board (75) formed with a positioning notch (75a) that engages with the switch display board (75) is fixed to the display panel face plate (2) with screws (75b), and a switch display board (75) is formed in the engagement hole (38) of the base member (3). 1 part (53) of the main body (4) to be locked
are fitted and locked, and the engaged part (7) of the h11 part (7)
73) and the engaging portion (41) of the switch body (4) can be freely attached to and detached from the base member (3) of the display panel face plate (2).

Figure 46 shows another embodiment of the operation section, in which a lock rotation section θ6) operated by a key is provided at the operation @ (7a) in place of the knob (74) of the previous embodiment. .

Figure 47 shows an example of the switch main body.
A plurality of contact portions (65) are arranged in the radial direction of the switch body (4a).
a), (65b>, r65c) are arranged, and the movable contact piece r65dl and the response piece r65e), (65f
), and the operation by the operating member (61d) is made into a multiple switch that can be operated by receiving each contact part r65bl, (65cl K). Along with this, the fixed part (66
) is also multilayered with many edges below 1' -fmg),
mg), ... are protrudingly provided h, and there is one fitting piece (64c), but the locking tube (56)
It is also wide. Other configurations include the switch body (
This is the same as 4).

Therefore, the unit (1) consisting of the display panel face plate (2) and the pace section (3) can be combined in large numbers to achieve miosis, and any switchboard surface and power distribution pattern can be set. . That is, the side wall r32a of the base member (3)
) and (32b) have symmetrical unevenness, so when N number of base members (3) are placed adjacent to each other, they are mutually IC-fitted and connected. Knead, 1111 wall 1.33), C
The same applies to 141. Each base member (3) has a leg (3
5) is inserted into the space between the crimp frames 0, and the claws (35a) are fitted into the fitting holes (Dl) to be fixed. The display panel face plate (2) has a power distribution pattern e'l according to its position.
), and if necessary, a bright part (24a) and a switch are provided. In addition, if necessary, use a partition plate (double the partitioning force) to divide it into appropriate categories.

In the switch (4), the operating part (61d/) is rotated by the rotation of the rotary operating part (61d/), and the actuated part (63f) inserted into the forked part (61h) is thereby rotated.
is pressed, and the contacts (
63d) and (63e) come into contact to turn on the switch, and perform a stepwise switching action according to the cam surface (61f). The locked part (53) of this switch body (4)
