Abstract

A kind of bearing that is used to install the electric component of switch for example or socket, this bearing has that to be fixed in for example be mechanism in the perforate on the mounting plane of partition wall, bearing has individual bottom surface, sidewall 4 and two lugs 2, lug slips in an opening of sidewall and therefrom stretches out, and has an elastic part 8 (a) that lug is pulled to the bearing bottom surface and (b) lug pulled out from opening.When for example socket was screwed on the assembly 7 that is connected with lug 2 with screw with electric component, lug was from the bottom surface pull-up, and at this moment lug is pressed on the installed surface back, and electric component presses the front of installed surface, and this bearing box is fixed.

Description

Holder for an electrical component

The invention relates to a kind of bearing of the electric component installation such as switch or the socket.

This bearing makes box-shaped usually, for example is installed on the wall, and various electric components are arranged in it, passes through, feeds in the box outside box and its sidewall or bottom have perforate to accept lead.These bearings can be installed with the ground, surperficial isoplanar of wall or partition wall, and these bearings often are to make the form that is called dried lining box.

The known ever-present installation question of dried lining box is, when box inserts in the hole of wall or partition wall, often is difficult for guaranteeing to make being tightened in wall or the partition wall back waltzs through this wall or partition wall so that box is fixed in the fixing of position with lug.

According to the invention provides a kind of Holder for an electrical component.Bearing has the mechanism in the perforate that is fixed in the mounting plane of partition wall for example.Bearing comprises a bottom, and 2 from the relative sidewall of this bottom extension and a flange outside each sidewall edge.Said mechanism has comprised two lugs, it is arranged in respectively in the opening on the corresponding a pair of opposing sidewalls, can slip into and therefrom stretch out, flexible part pulls to the bottom with this lug, each lug is connected with the interior corresponding assembly of sidewall, available screw is fixed an electric component on the assembly, because element is tightened on the said modules, cause element to press close to the front or the above-mentioned installation surface of above-mentioned flange, and above-mentioned bead ear is tightened up in the back of for example partition wall, thereby bearing is fixed on the position of above-mentioned perforate.

Elastic part can be a flat spring, is bonded between two lugs and by below at the bottom of the bearing.

Another elastic part is to adorn a spring clip at each sidewall, be located between the inside and outside wall of one of them sidewall, and make its bottom that leans against the base of this sidewall, and, shift to the bottom with its lug thereby order about this assembly to pressing down connected assembly.

Two lugs are loaded onto into the following side of gradient respectively, thereby when bearing is pushed perforate, and lug is pushed in the bearing and leaves original position, when lug smoothly by behind the partition wall, elastic device sets back it.

Preferably make bearing make the box shape, open front, and make by thermoplastic.

In order to understand the present invention better and to show how it works, below with way of example with accompanying drawing reference number in addition, wherein:

Fig. 1 is the perspective view that Holder for an electrical component is partly cut open;

Fig. 2 is the cutaway view of part bearing among Fig. 1, and its characteristics are described;

Fig. 3 shows the another kind of example similar to Fig. 2.

Fig. 1 and Fig. 2 show a bearing, and its form is so-called dried lining box 1, is used for electric component such as switch or socket (not shown).Electrical box 1 has the isoplanar mechanism of mounting plane that is fixed in basic and for example wall, ceiling, partition wall.This mechanism comprises two lugs 2, slips in its respective openings 3 on the opposing sidewalls 4 of electrical box 1 and stretches out.In a single day opening 3 be a cross substantially, and each lug all can be by the inside of electrical box 1 opening 3 of packing into suitably, and packs into wherein, it just can slip into.Each lug 2 is connected with the interior corresponding assembly 5 of electrical box, and assembly 5 has a part 5A to fit between the pair of posts 6, and pillar 6 plays guide effect for the slip of lug 2.Other of assembly 5 partly are slide blocks, and its top is screwed hole 7.

Lug 2 can pass through wall or next door smoothly when guaranteeing perforate that electrical box 1 inserts wall or partition wall, to be in extended state as a flat spring 8 of elastic part, walk around the bottom surface of two lugs 2 and electrical box 1, so flat spring 8 is straining at lug towards cartridge bottom.

Be represented by dotted lines each assembly 5 and its lug 2 among Fig. 2 and swing situation into the position through opening 3.In case after going into the position, flat spring 8 is fitted round lug 2 heads, is straining at bottom surface and another lug 2 of walking around electrical box 1.The bottom of electrical box 1 is close in the bottom of each assembly 5, has limited moving down of lug 2 like this.5A partly is tightened up by fexible bias pressure and is affixed to sidewall 4, has guaranteed that therefore the lug 2 that makes up often normally is in position as shown in the figure.

We can see that the downside of each lug 2 is made oblique, and when bearing was pushed into the perforate of a wall or partition wall, the limit of perforate was run on the inclined-plane of lug 2, and lug 2 is pushed to bearing inside, is resisting fexible bias pressure.When lug 2 smoothly when the wall by thereafter or partition wall, they automatically are drawn back into illustrated position.

Then, an electric component can utilize screwed hole 7 usefulness screws to be fixed on above the assembly 5, cause element to be close to the front of flange 1A of electrical box 1 or the installed surface of wall or partition wall, and make lug 2 be drawn the back side of pasting wall or partition wall, like this electrical box 1 is fixed on the position in the perforate.In other words, when element was screwed on the assembly 5, they were up drawn as shown, and lug 2 and flange 1A are pulled simultaneously, therefore will clamp on wall in the middle of them or partition wall.

According to common operating position, perforate or wash the suitable position that the position can suitably be configured in electrical box 1 open is so that the turnover of lead.

In form shown in Figure 3, the elastic part that lug 2 is pulled to electrical box 1 bottom is the form of a spring clip 9.Spring clip 9 is elongated, and 2 free ends 10 are arranged, and every end has a crooked position 11, and it is extended down to down the section of stretching 12, and is parallel each other, and is pressing the relative section of assembly 5.The section of stretching 12 passes electrical box 1 by the perforate 13 and sidewall 4 lower sides of bottom under two of spring clip 9, the upwards curved then outer wall that makes it to hug sidewall 4.The outer wall of sidewall 4 is a projection 14 near its bottom.On its each side two by spring clip 9 on 15, two of the sections of stretching the section of stretching 15 collided by bending and be interconnected in position 16.Form a support that connects projection 14.

Similar first kind of example, lug 2 and assembly 5 can tilt in box, but on this occasion down, such inclination is to take place under the fexible bias pressure of antagonistic spring clip 9, and spring clip is the position of ordering about lug 2 and assembly 5 to Fig. 3.In addition, the part 11 of spring clip 9 can pressed the bottom angled of assembly 5 to box 1, so lug 2 also is pressed towards the bottom of electrical box 1.

When an electric component was fixed on above the assembly 5 by a chain for binding criminals hole 7 usefulness screws, assembly 5 and their lug 2 were also up drawn, and therefore overcame the fexible bias pressure of clip 9 and pushed position 10 and 11 to one side.

In two disclosed examples, can as long as electric component is backed out,, cause lug 2 antagonistic spring bias voltages to pull in the box easily with the within the walls taking-up of electrical box 1 from its installation with assembly 5 pullings, lug 2 can be smoothly by the perforate on the wall like this.
