Description

Board for distributing appliance

Technical field

The present invention relates to the board for distributing appliance of use in a kind of embedding type distributor construction.

Background technology

In the past, provide a kind of a part has been enclosed in embedding type distributor in the embedding hole that forms on the construction surface as wall with embedding form.For this distributor is installed to the mode of construction surface, a kind of mode that distributor is installed in the frame shape holding member that is fixed on the construction surface was provided in the past.The installation dimension that makes distributor is with respect to the holding member standardization, common many uses can be in 1～3 scope the holding member of the distributor of installation unit size, can perhaps can in 1～3 scope, identical shaped distributor be installed on the holding member being installed on the holding member after the various distributor combinations such as switch, socket, telephone socket, TV socket.For example, switch and socket can be installed on 1 holding member, 2 switches perhaps are installed on holding member.

In addition, as holding member, provided to have the holding member that 3 parts of the decorative panel that exposes window of exposing distributor constitute when keeping the installing frame of distributor when being fixed on the construction surface, combine and cover the sheet frame that is formed at the embedding hole on the construction surface with installing frame and combining and cover installing frame or sheet frame with sheet frame in the past.This holding member is owing to need 3 parts, thereby part count is many slightly and take a lot of work during construction cost.

For this reason, proposed a kind of use, constituted the scheme (spy opens flat 11-243615 communique) of holding member by mounting panel and 2 parts of decorative panel installing frame and the incorporate mounting panel of sheet frame.In this communique, as shown in figure 25, show and be applicable to the holding member of seeing distributor (illustrated example is a switch) 1 from the front, on distributor 1, see in the length direction two sides of body 11 each outstanding setting-from the front mounting jaw 12 with the body 11 that forms rectangle.The front surface of mounting jaw 12 (Figure 25's is top) tilted rearward makes it the side away from body 11, and the rear surface of mounting jaw 12 is perpendicular to the side of body 11.

On the other hand, as Figure 23 and shown in Figure 24, mounting panel 2 formation that constitute holding member are rectangular box-like, in order at central portion distributor 1 to be installed, form the openning of offering to rectangle 21.At the outstanding backward stator 22 that is provided with along opening edge of a sidepiece of openning 21 Widths, in the outstanding backward operation strip 23 that is provided with along opening edge in the other side of openning 21 Widths.Clamping operation strip 23 and is formed 3 slit 24a～24c along operation strip 23 at the opposition side of openning 21, makes operation strip 23 have flexibility on openning 21 Widths.On stator 22 and operation strip 23, form and be arranged on 1 group of a pair of maintenance groove 22a that the mounting jaw 12 on the distributor 1 engages respectively, each 3 groups of 23a.That is to say, as be distributor 1 shown in Figure 25 that can be equipped with 3 on mounting panel 2, when 1 distributor 1 only was housed, 3 places can be selected in the position of installation on mounting panel 2.In other words, illustrated mounting panel 2 can be used as 3 uses.

At the both ends of mounting panel 2 length directions, be formed with and insert the fixedly box usefulness hole 32 of hold-down screw 7 (with reference to Figure 28) usefulness of tool of conduct.As shown in figure 28, in construction surface W, during embedding switch enclosure 5 (with reference to Figure 28), hold-down screw 7 is tightened onto on the switch enclosure 5.In addition, mounting panel 2 is fixed to after construction surface W goes up, decorative panel 3 is installed on the mounting panel 2.

In addition, in being installed to distributor 1 on the mounting panel 2, under the state that the mounting jaw 12 with distributor 1 one sides inserts among the maintenance groove 22a that is provided with on the stator 22, make the mounting jaw 12 pushing operation strip 23 of distributor 1 another side, simultaneously distributor 1 is pushed in the openning 21.By this operation, mounting jaw 12 and maintenance groove 22a, the 23a engaging, distributor 1 remains on the mounting panel 2.

As mentioned above, because in distributor 1 and the deflection that utilizes operation strip 23 when mounting panel 2 engages, thereby, the operation strip 23 in the mounting panel 2 is rearward given prominence to bigger size in order to make operation strip 23 easy deflections.That is, as shown in figure 26, operation strip 23 is also rearward more outstanding than the periphery of mounting panel 2.

If operation strip 23 is also rearward more outstanding than periphery on mounting panel 2, then when carrying or during the stock, as shown in figure 27, mounting panel 2 is needed bigger space when overlapping.This problem not only takes place in operation strip 23 occasion also more outstanding towards the rear than the periphery of mounting panel 2, and also can take place in the rearward outstanding occasion of stator 22.In addition, if stator 22 or operation strip 23 are also rearward more outstanding than the periphery of mounting panel 2, during then with mounting panel 2 overlapping conveyings etc. under the situation, because of ledge may damage other mounting panels 2.

In addition, as shown in figure 28, when using switch enclosure 5 to construct, because of there being the sleeve pipe 6 that imports electric wire in the switch enclosure 5, when distributor 1 biasing was provided with in switch enclosure 5, operation strip 23 or stator 22 were outstanding outside switch enclosure 5 sometimes, and mounting panel 2 can not be installed.

In order to address the above problem, consider operation strip 23 is designed to the scheme also rearward outstanding unlike the periphery of mounting panel 2.But, outstanding size as operation strip 23 reduces, then operation strip 23 just becomes and is difficult to deflection, thereby in order to ensure the deflection of operation strip 23, must strengthen the flexibility (being easy deflection) of operation strip 23, as a result, keep the power of distributor 1 to diminish, the problem that distributor 1 easily comes off from mounting panel 2 takes place.

Embodiment

Embodiment 1

The board for distributing appliance of present embodiment is fixed to the mounting panel 2 on the construction surface as wall when keeping distributor 1 and the decorative panel 3 that covers mounting panel 2 and the part of distributor 1 is exposed constitutes as shown in figure 23.The present invention has feature on the structure of mounting panel 2, so following explanation mounting panel 2.

As Fig. 2～shown in Figure 4, mounting panel 2 forms rectangular box-like by the synthetic resin with insulating properties, as shown in Figure 4 and Figure 5, keeping switch or the such distributor 1 (Fig. 4 shows socket as distributor 1) of socket on the rectangular aperture window 21 of central portion being arranged at.Mounting panel 2 has a pair of installing frame sheet 30 that is arranged on the openning 21 length direction two ends with linking into an integrated entity, and connects a pair of connection box sheet 20a between two installing frame sheets, 30 each end, 20b respectively.

As shown in Figure 1, at the back side of a connection box sheet 20a, along a lateral margin formation stator 22 of openning 21 Widths, at the back side of another connection box sheet 20b, along another lateral margin formation operation strip 23 of openning 21 Widths.Operation strip 23 forms on the Width of openning 21, makes it to be deflection.The concrete structure of operation strip 23 will be narrated in the back.To this, in structure in the past, also the side of supporting or opposing is outstanding than the periphery of mounting panel 2 for stator 22 and operation strip 23, but in the present embodiment, at connection box sheet 20a, in 20b and the installing frame sheet 30, the part (with reference to Fig. 9) of also giving prominence to towards back of the body side than the periphery of mounting panel 2 is not set.In addition, at each connection box sheet 20a, the back side of 20b, along the outer peripheral edges formation compressing tablet 26 of mounting panel 2, the back side of compressing tablet 26 flushes with the back side of installing frame sheet 30.

In stator 22 and operation strip 23, in the face of on the face of openning 21, being provided with respectively 1 group of engage with each a pair of mounting jaw 12 on body 11 two sides that are arranged on distributor 1 is a pair of maintenance groove 22a, respectively 3 groups of 23a.Thereby, keeping groove 22a by making the mounting jaw 12 on the body 11 that is arranged on distributor 1 with each, the 23a engaging can be exposed the part (handle of switch or the socket of socket) of distributor 1, and distributor 1 is installed on the mounting panel 2 from openning 21.Keep groove 22a on mounting panel 2, the corresponding position of 23a forms the inside and outside affirmation window 22e that connects respectively with each, 23e, and by confirming window 22e, 23e can confirm to keep groove 22a, and whether 23a engages with mounting jaw 12.

As shown in Figure 6, at the back side of connection box sheet 20a, connect position parallel and the dowel 27a between the compressing tablet 26,27b forming one on the compressing tablet 26 with stator 22.Dowel 27a, 27b can form (dowel 27a) or form (dowel 27b) with respect to stator 22 diagonal cross ground shown in Fig. 6 (a)～(f) perpendicular to stator 22 ground.By this dowel 27a is set, 27b can improve the intensity of mounting panel 2, and in external force when the thickness direction effect of mounting panel 2 or effect have the external force of reversing mounting panel 2, can suppress the warpage of mounting panel 2, prevent that distributor 1 from coming off from mounting panel 2.In addition, as the structure that realizes this purpose, shape the best of Fig. 6 (f).

Fig. 6 (a) by this structure, even external force acts on the mounting panel 2, also can suppress the distortion of mounting panel 2 for equally spaced to be provided with the figure of odd number perpendicular to the dowel 27a of stator 22 on the length direction of openning 21.In addition, shown in Fig. 7 (a), under the state that mounting panel 2 is fixed on the construction surface W, if effect pushes the power of distributor 1 direction, connection box sheet 20a then, the interior perimembranous of 20b is pushed among the embedding hole H, and deflections take place in mounting panel 2.This deflection has the mounting jaw 12 of removing distributor 1 and the tendency that keeps groove 22a to engage, thereby distributor 1 may come off from mounting panel 2.Particularly, in mounting panel 2 the position of easy deflection near the central portion of openning 21 length directions, pass through said structure, 1 dowel 27a is positioned at the central authorities of openning 21 length directions, thereby the external force on affacting distributor 1 can pass to deflection stator 22 by dowel 27a when having an effect.

In order to relax this problem, consider as Fig. 6 (b), make to be formed at dowel 27a and to become arcuation with bight between the stator 22, make it to connect sleekly, thus the stress of mitigation generation on dowel 27a and stator 22.Certainly, as mentioned above, when dowel 27a is positioned at openning 21 length directions central, because the deflection of mounting panel 2, coming off of distributor 1 may be taken place, thereby preferably shown in Fig. 6 (c), by being provided with even number dowel 27a, be not provided with dowel 27a in the central authorities of openning 21 length directions.As the structure adopting, shown in Fig. 7 (b), even owing to separate compressing tablet 26 and stator 22, the power that distributor 1 pushes among the embedding hole H is had an effect, connection box sheet 20a deflection, stator 22 also is difficult to open towards the outside, as a result, reduced the possibility that distributor 1 comes off.

On the other hand, the dowel 27a of the above-mentioned shape that uniformly-spaced is provided with by length direction at openning 21, it is little to suppress the effect that mounting panel 2 that external force causes reverses, therefore, consider shown in Fig. 6 (d), the dowel 27b with respect to compressing tablet 26 and stator 22 diagonal cross to be set.Adopt the dowel 27b of such shape, can suppress reversing of mounting panel 2.In addition, as Fig. 6 (e), merge, the dowel 27a perpendicular to compressing tablet 26 and stator 22 is set, then suppress the effect that mounting panel 2 reverses and uprise with the dowel 27b of diagonal cross.But, as Fig. 6 (e), if dowel 27a is positioned at the central authorities of openning 21 length directions, then for the above reasons, the possibility that distributor 1 comes off uprises slightly, thereby wish most as Fig. 6 (f), in the structure of Fig. 6 (e), omit the form of the dowel 27a that is positioned at openning 21 length direction central authorities.In addition, above-mentioned dowel 27a, the structure of 27b is an example, can suitably combine.

In addition, be provided with on the connection box sheet 20b of operation strip 23, along 3 slit 24a～24c of length direction formation of openning 21.Each slit 24a～24c is inside and outside connection box sheet 20b, and each a pair of 1 group maintenance groove 23a is corresponding with 1 slit 24a～24c.Between the slit 24a～24c of adjacency, be provided with and separate muscle 24d.The slit 24b that is positioned at openning 21 length direction central portions is the linearity along openning 21 peripheries, be positioned at each slit 24a of openning 21 length direction both sides, 24c has the straight line portion of arranging with slit 24b point-blank on the central portion side of openning 21 length directions, simultaneously, in the both end sides of openning 21 length directions, on the close direction of installing frame sheet 30, has crooked L shaped part.L shaped part has perpendicular to straight line portion and to vertical portion that installing frame sheet 30 prolongs and the transverse part that prolongs and tilt near the direction of installing frame sheet 30 in the lateral of mounting panel 2 length directions from connecting portion.In openning 21, with the corresponding corner parts in the both ends of operation strip 23, along being arranged on slit 24a, the transverse part on the 24c forms grooving 21a, forms deflection sheet 28 between grooving 21a and transverse part.That is, the two ends of operation strip 23 length directions are connected by deflection sheet 28 other positions with connection box sheet 20b, and in addition, the central portion of operation strip 23 separates muscle 24d by 2 and is connected with other positions of connection box sheet 20b.In addition, from above-mentioned slit 24a, the shape of 24c end as can be seen, at the Width of openning 21, deflection sheet 28 is narrower than the width of operation strip 23, thus at the Width of openning 21 than operation strip 23 easy deflections.In addition, for respect to an end that is connected with operation strip 23 in deflection sheet 28, the other end tilts to form with respect to the periphery of openning 21, makes it near the installing frame sheet.

In connection box sheet 20b, slit 24a～24c and a side opposite in clamping with operation strip 2, be provided with 2 and run through the inside and outside auxiliary slit 24e of connection box sheet 20b, 24f.At slit 24a～24c and auxiliary slit 24e, form along muscle 24g between openning 21 length directions between the 24f.An auxiliary slit 24e is at cross-over connection slit 24a, and the position of 24b is parallel to slit 24b and forms, and another auxiliary slit 24f is at cross-over connection slit 24b, and the position of 24c is parallel to slit 24b and forms.Promptly, when the external force of the central portion deflection of operation strip 23 is had an effect, by separating muscle 24d, with external force be delivered between slit 24a～24c and auxiliary slit 24e, the 24f between on the muscle 24g, between muscle 24g deflection, thereby can make the central portion deflection of operation strip 23.

At this, stator 22 and operation strip 23 are to leave formation with openning 21 all intermarginal, form utensil receiving portion 22b between the periphery of openning 21 and stator 22, in addition, and formation utensil receiving portion 23b between the periphery of openning 21 and operation strip 23.Form each utensil receiving portion 22b, 23b contacts the both sides of front surface length direction in the body 11 of distributor 1.Therefore, the part of distributor 1 is exposed from openning 21, with the mounting jaw 12 of distributor 1 with keep groove 22a, the 23a engaging, simultaneously, by with utensil receiving portion 22b, the 23b contact remains on distributor 1 on the mounting panel 2.

Under this state, to distributor 1 effect (for example, distributor 1 be a socket, the situation of unplugg etc.) when the external force in mounting panel 2 the place aheads, by distributor 1 and utensil receiving portion 22b, 23b contacts, and can prevent that distributor 1 from coming off from mounting panel 2.In addition, (for example, distributor 1 is a switch when the external force at mounting panel 2 rears to distributor 1 effect, when switching manipulation, make the situation of thrust etc.), by the mounting jaw 12 and maintenance groove 22a of distributor 1, the 22b engaging can prevent that distributor 1 from coming off from mounting panel 2.And, two ends in the operation strip 23 of mounting panel 2, be provided with on the Width of openning 21 narrow and deflection sheet 28 that tilt with respect to the periphery of openning 21 than the width of operation strip 23, and, the engaging position of mounting jaw 12 and maintenance groove 23a is in the rear end side of operation strip 23, thereby on distributor 1 rearward during the bigger external force of effect, 28 torsional deflections of deflection sheet, the rear portion of operation strip 23 becomes the shape of pouring openning 21 inboards into, mounting jaw 12 becomes darker with keeping engaging of groove 23a, can prevent coming off of distributor 1.

In addition, in the present embodiment, as mentioned above, near stator 22, in order to improve the intensity of mounting panel 2, form dowel 27a, 27b, thereby can suppress the external force of mounting panel 2 thickness directions or reverse the distortion of the mounting panel 2 that the external force of mounting panel 2 causes, prevent that mounting panel 2 warpages or distributor 1 from coming off from mounting panel 2.Near operation strip 23, the structure as improving mounting panel 2 intensity shown in Fig. 8 (a), is provided with dowel 29, and these dowel 29 one connect between the compressing tablet 26 and a muscle 24g that is arranged on mounting panel 2 peripheral parts.Dowel 29 is provided with a plurality of on the length direction of openning 21 with appropriate intervals.But 27a is same with dowel, and in order to improve the effect that prevents that distributor 1 from coming off, the central authorities that are preferably in openning 21 length directions are not provided with dowel 29.And, dowel 29 preferably is set, make it center symmetry with respect to openning 21 length directions.Same with the reason that dowel 29 is set, the width megarelief is muscle 24d at interval, can suppress the deflection of mounting panel 2, thereby for a muscle 24d, wishes that the width the earth forms as far as possible.In addition, example illustrates dowel 29 is not set in contrast in Fig. 8 (b), a narrower structure of muscle 24d width.

For the distributor 1 that will remain on the mounting panel 2 takes off, in stator 22, between each maintenance groove 22a of 1 group, form dismounting groove 22c, on mounting panel 2, form the inside and outside removal hole 22d that connects with the corresponding position of dismounting groove 22c.That is to say, as by removal hole 22d the instrument the manifold screwdriver being inserted the dismounting groove 22c from the front face side of mounting panel 2, then instrument can with the contacts side surfaces that remains on the distributor 1 on the mounting panel 2.Under this state, exert all one's strength on the instrument of affacting, make it to push the body 11 of distributor 1 to operation strip 23, according to lever principle, with less power with regard to deflection operation strip 23, can remove the fastening state of the mounting jaw 12 of the maintenance groove 22a of stator 22 and distributor 1, take off distributor 1 from mounting panel 2.At this, removal hole 22d and confirm that window 22e, 23e (that is, running through the inside and outside hole of mounting panel 2) opening is quadrangle, it is circular-arc that all bights are connected into, thereby reduce concentrating of stress.Simultaneously, by acting on the external force on the mounting panel 2, the also related effect that has inhibition distributor 1 to come off.
