Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to wiring devices such as the f3AVi switch and v switch.

In conventional switches that display the load status using a display element, a display element such as a neo-shirashi tree or a light-emitting diode is provided in a movable hashidle made of cedar wood.

Therefore, when the handle is operated to open and close the contacts, the leads of the display element also move each time the handle moves, and there is a danger that the display element itself may be damaged. After installing the display element in the mano-hasidor, the display element is not electrically insulated because the hashidle itself is located above the switch mechanism where current flows and arcs fly when the contacts open and close. It is easily affected by secondary arcs, etc., and is prone to failure. Furthermore, there was a problem with the Hasidor itself, which was difficult to assemble, such as the opening IwJ part, and the display element moving.

The present invention has been proposed in view of the above-mentioned points, and an object of the present invention is to provide a mounting device that is easy to assemble K1 without causing failures or accidents.

Embodiments of the present invention will be described in detail below with reference to the drawings. (1) in the diagram

In the direction, the opening S□□□ has a compensation dimension of the mounting frame (1) of 1
Assuming that the ribbon dimension is b, the horizontal dimension of the opening S (to) is a dimension C larger than 1, and the vertical dimension #'i is a dimension d smaller than b. The mounting frame t is attached to the abutting part □□□ of the lower frame j above.
A protrusion (26a) that fits into the hole (4) of No. 11 is formed,
The attachment frame tll and the lower frame (241) are positioned at regular positions due to the structure of the projection (26a) and the hole (4).

2η is a second long groove formed on the periphery of the opening (c) of the lower frame □□□, and provided with a next rib and □□□. The abutment part of the lower frame corresponding to the mounting hole (3) of the mounting frame m has a notch 4 which loosely fits with the screw (2) when the lower frame is brought into contact with the construction surface W. is formed. In addition, the lower frame (241 is made of glass fiber, for example, PB)
It is formed by plastic molding of thermoplastic resin such as T resin, Noryl resin, and ABS resin, and has both elasticity and hardness.

Seki is a rectangular frame-shaped plate body, has a bottom surface (30 m) that is approximately the same size as the bottom frame, and has a lip that fits with the bottom frame (241 norizuso), and a long groove (c). It is integrally formed with a positioning protrusion Q that fits into the lower frame (

A display terminal consisting of a resistor and a neon lamp arranged on the board '81 is inserted into both contact terminals. The field is a lamp cover, and both sides of this lamp cover field are
The substrate η is held therein, and a transparent body 4 protruding from the upper surface of the rash cover is positioned above the display element 4 to display blinking of the display element. This transparent button and the display element □□□ are placed directly in one hole on the side of the entrance part 7) of the cover madder, and then inserted into two 17 insertion holes respectively, and the end of the cover is inserted into the irises. They will be displayed by blinking each time. The terminals are display pieces, and are placed in a dormant manner at the slot board mouth and the fixed terminal machine fAI621, respectively. Below the Aya display kite E1231, a board 6η and a variable current truss (2) are arranged, and the movable contact plates 14 to 14 and the fixed clapper board (6) are located on the side of the variable current truss (ω). The display piece (74 is the 1st hole of the Suprishiji vehicle is elastically contacted with the lower part of the 13 bar and is urged downward, and its lower part protrudes from the lower part of the body.This display piece αmari is external) When inserting and connecting the electric wire to each Naruko Itaduru 1 Kei, it is connected repeatedly and indicates the next one, and when the il- is inserted, its tip hits the protrusion of the display piece σ4 and the display piece - is moved upward. Therefore, when In is connected to each pane member i[JE, it is retracted into the @sFi body under the display piece and becomes invisible. σQ connects the turtle to pressure m. V is a locking spring made of insulating material, and V is a release button made of insulating material. The above-mentioned switch mechanism is housed in the jf5' side, and the cover is screwed in and installed with the assembly screws (9). Assembly and installation of the switch body (7) is completed by screwing into the screw hole (8) of the frame 11).

Therefore, when installing the switch body (7) on the construction surface W, first, as shown in Fig.
) to the mounting frame il+ and apply alli-, insert the mounting frame (1) into the pocket X and the construction surface WVc screws (2)
Therefore, it becomes hard. Next, attach a decorative material Y such as a ribbon to the construction surface W, cut out the decorative material Y along the mounting frame (1) K, and use it for regular use.
), then attach the lower frame example to the lower surface of the mounting frame (1).

In this case, first, the notch (2a) is fitted to the screw (2), and the mounting frame (1) is positioned on the lower frame by passing through the entire opening i2!5. Therefore, the lower frame example can be mounted below the mounting frame il+ without removing the mounting frame fi+. Set the mounting frame (1) to the abutment part [present] of the lower frame example.
At the same time, fit the hole (4) of the mounting frame fil into the protrusion (26m) of the lower frame (end) and tighten the screw (2). Therefore, even if the decorative material Y is thick, by tightening the screws (2), the entire decorative material Y that is in contact with the lower frame example is pressed against the construction l1IIW side. Next, fix the plate main body to the mounting frame (1) with the fixing screws 141, and then fit the front plate (6) into the window hole (b) and expose it to the concave chamber α4 of the middle handle 1107. 1 Push in the circle (material) lug Uυ of the plate (6) to hold the protrusion (g) of the cylindrical lip in the locking piece of the identification spring box, and then attach the switch body (7).
is attached. Therefore, there is no need to worry about dirt on the inner frame (101) due to the mounting material Y of the rear.In this case, the inner frame L is fixed to the mounting frame 11+ and By forming the switch body (7)
The operating body is used to position the front plate (6), and even when the front plate (6) is larger than a medium-sized handle (10J), the reversal angle can be maintained at a known position.

Figure 6 shows another embodiment, in which a single sui-shichi main body (7
), and the top has a movable hashidor+l
fJ is loosely fitted, and the switch is below this hasidor (lO).
The city mechanism is housed. and Hasidor (l)
On the sides of O) are two display elements d that display the load status.
This display element (support) is separated from the main structure and electrically insulated.As mentioned above, the present invention is possible! 1Ii2IO■ The display element is fixed in a recess in the switch body which is located in a different position from the switch mechanism which is located below the switch mechanism. Since the display element is not placed above the switch, the display element is electrically insulated from the switching mechanism, and there is no risk of damage to the display system due to arcing when the contacts open or close, or electrical short circuits that could cause subsequent damage. Yes, the display element itself does not move like a hashidor, so there is no #-, and there is no display element in the hashidor that moves, so it is necessary to set the display element and the hashidor [#4] at the same time. It is easy to assemble without any hassle.
