Abstract

The utility model discloses a push switch type socket, which comprises a socket body, jacks and switches. The utility model is characterized in that the switch is a push type switch, and the jacks are divided into a plurality of groups. Each of jacks of each group is corresponding to one switch which is connected in series to a circuit of the jack. The utility model breaks through a traditional socket and is a novel push type switch. The utility model has a large board button, can be touched and pressed conveniently and is free from an indicator light, and the on-off state of the utility model is obvious.

Description

Push switch formula wiring board

The utility model relates to a kind of push switch formula wiring board.

Wiring board (claiming socket, row Soviet Union, floor mop Soviet Union etc. again) at electrical appliances that is absolutely necessary such as family, office, factories, is ubiquitous in the world today.But the design of existing wiring board is also not fully up to expectations.Do not have switch on the wiring board that has, what have does not then have an indicator light; Though what have has switch or an indicator light, the two has only one.Even the existing switch of the wiring board that has has indicator light again, but do not accomplish that every group of jack all has a switch and an indicator light, so, the electrical equipment that is inserted on the same wiring board can only be (will open if an electrical equipment is arranged with opening with closing, other will close, then need the plug of other electrical equipment is extracted from wiring board), very inconvenient.

On the other hand, set switch on the present wiring board all is a dial type, and it is to close that the one end is pressed, the other end by next for opening.Because shift knob is little, stirs the position again exactly, it is extremely inconvenient to operate, more inconvenient when especially using for old man, child or night.

The purpose of this utility model is exactly to provide a kind of push switch formula wiring board in order to overcome the above problems, and uses more conveniently, operates simpler.

The utility model realizes that the scheme of above-mentioned purpose is: a kind of push switch formula wiring board, comprise wiring board main body, jack, switch, and it is characterized in that: described switch is a push switch; Described jack has many groups, and corresponding every group of jack has a switch, is series on the circuit of this jack.

Adopt the beneficial effect of above scheme: the utility model uses push switch, when wanting to open or close, only need press the button, and unclamps then to get final product, and does not need switch is accurately toggled it to certain position, uses easy to operate.Every group of jack all has independent switch control, and switch control is followed one's bent, and is inserted in the electrical equipment on this wiring board even have only one will open, and also need not pull up other plugs.

Also in conjunction with the accompanying drawings the utility model is described in further detail below by specific embodiment.

Embodiment one: see Fig. 2 a, 2b, shown in push switch formula wiring board, comprise wiring board main body 100, jack 200, switch 300, it is characterized in that: described switch 300 is push switch; Described jack 200 has many groups, and corresponding every group of jack 200 has a switch 300, is series on the circuit of this jack 200.

In order to indicate the open and close state of every group of jack, the indicator light 301 of on each switch 200, all connecting (rather than only establishing a master pilot lamp), its state can come into plain view like this.

Fig. 1 shows a kind of structure of push switch.Among Fig. 1, described push switch 300 comprises shift knob 1, switch frame 3, changes top 4, first contact chip 5, second contact chip 11, switch sheet metal 6, face 7 and switch spring 9, wherein shift knob 1, switch frame 3, commentaries on classics top 4, a face 7 and switch spring 9 are arranged in order from top to bottom, changeing column-shaped projection 41 on the top 4 extend in the cavity in the switch frame 3, the column-shaped projection 71 that props up face 7 tops extend in the cavity that changes in the top 4, and the column-shaped projection 72 of below extend into switch spring 9 inside; Described face 7 can rotate under the restriction on switch spring 9, commentaries on classics top 4, and the angle of rotation is unrestricted; Prop up the square that there are four settings face 7 tops, each square upper surface is the inclined-plane, below 4 outer surfaces of commentaries on classics top with below switch frame 3 inner surfaces four corresponding inclined-planes is being arranged also, and they and the mutual stressed result in inclined-plane who props up on the face 7 can make a face 7 rotations; Be fixed with switch sheet metal 6 on a face 7, its two ends respectively have the position of 61, two contacts 61, a contact corresponding with the contact 51,111 on first and second contact chip 5,11.Switch spring 9 lower ends are supported on the base 8.

Also have spring 12 above switch frame 3, the height when it freely extends is higher than the height of switch frame, can withstand on shift knob 1 below, is used for making when release button shift knob 1 free return, and keeps a suitable free travel when pushing.

The operation principle of above-mentioned push switch is as follows:

The supposition switch is in " disconnection " state (see figure 3) earlier, this moment the first contact chip (sheet metal, as copper sheet etc.) angle of the straight line that two contacts (slider material can be copper, silver etc., so can be described as " silver nail " again), 51,111 straight lines that constitute and two contacts on the switch sheet metal 6 61 constitute on 5 and second contact chip (sheet metal) 11 is 90 to spend.

When pressing shift knob 1 (referring to Fig. 5), commentaries on classics top 4 moves down, and it is together downward to promote a face 7, owing to prop up face 7 and change the inclined-plane pressure on 4 on top, makes a face 7 rotate 45 together with switch sheet metal 6 and spends.

Trip switch button 1 back (referring to Fig. 6), under the elastic force effect of switch spring 9, pull switch sheet metal 6 parts such as grade move up, simultaneously because the pressure between a face 7 and switch frame 3 inclined-planes, drive a face 7 and continue rotation 45 degree with switch copper sheet 6, make on the switch sheet metal 6 the silver nail just in time with first contact chip 5 and second contact chip 11 on two contacts 51,111 contact and the (see figure 4) of switching on.Simultaneously, indicator light is shinny.

The process of turn-offing is then opposite.

In order to be convenient to operation more, the utility model or designed big plate button, specifically, the width of described shift knob 1 is more than or equal to the lateral separation between inner two jacks of every group of jack, and like this, its size is much larger than conventional push button, is easy to touch obtain.But its size can not exceed between each button in the phase mutual interference.
