The pull-switch with two phase socket of the utility model is especially suitable for being used in the countryside of China.

Description

Pull-switch with two phase socket

The utility model belongs to the electric switch field, particularly belongs to the pulling switch field that has the two-phase socket.

Existing pulling switch has only single switching function, can not be used as socket and use.(for example air blast etc.) has to reinstall socket when people will increase electrical appliance temporarily, uses very inconvenient; If mounting receptacle is not made contact and meet an urgent need temporarily, be absolutely unsafe again; Particularly, be sought after a kind of pulling switch that has socket in the present rural area of China.In case need the interim electrical appliance that increases, only need the plug of electrical appliance can be solved interim emergency requirement once inserting on the pulling switch box.

Each parts of the pulling switch of current trend all are mounted on the upper surface of switch enclosure base.Has only several holes (see figure 1) below the base.Still the space of leaving about half except that these holes below base does not add utilization, and the sidewall of base does not play one's part to the full yet, and remains further to be developed.

The purpose of this utility model is the structure of existing pulling switch is improved, and makes full use of the free space of existing pulling switch base, and a kind of pulling switch that has the two-phase socket is provided.

Existing pulling switch comprises lid, base and is fixed on the disk of cranking arm, transfer, stage clip, first contact and second contact on the base upper surface, realizes the break-make of two contacts when backguy drives when cranking arm swing by switching disk and stage clip.This pulling switch is known, therefore needn't be described in detail its structure here.

Improvement of the present utility model is to be provided with two parallel slits on the sidewall of base, their length and width size and spacing will be suitable for the insertion of the inserted sheet of two-pin plug, and on the bottom surface and two positions slit correspondence, fix two metal intermediate plates respectively, the position of intermediate plate and shape will be suitable for electrically contacting with realization with the engagement of two-pin plug inserted sheet, intermediate plate and exit contact are communicated with, promptly be connected on the phase line of electrical network, another phase line of another intermediate plate and electrical network links to each other.

For simplicity, a said intermediate plate directly is fixed on the fixed screw of said exit contact.

Describe embodiment of the present utility model with reference to the accompanying drawings in detail.Wherein:

Fig. 1 is the bottom view of the utility model pulling switch.

The implication of each label is as follows among Fig. 1:

1,2---fixing hole;

3,4---advance wire hole;

5---the backguy hole;

6,7---the contact fixed screw;

8,9---intermediate plate;

10,11---slit;

15---sidewall.

Fig. 1 is the schematic bottom view of the utility model pulling switch base.As shown in Figure 1, the base of pulling switch is the oblate cylindricality of hollow of end sealing basically.Be provided with fixing hole 1,2 in the bottom of cylinder, be used for switch pedestal is fixed on wall; Also be provided with switch into and out of line hole 3,4, be used to draw that switch and phase line of electrical network join into and out of lead-in wire; Also be provided with backguy fairlead 5, reach the fixedly screw hole 6,7 of the screw of two contacts of pulling switch.Around the 1-7 of hole, leave more free space.

Pulling switch of the present utility model has been to make full use of these free spaces on the base to the improvement of existing pulling switch.Two isometric wide slits 10 and 11 that are parallel to each other promptly are set on the wall 15 of cylindrical base, length and width that slit 10 and 11 length and width are larger than plug slice, the distance between two slits 10 and 11 are substantially equal to the distance between two inserted sheets of plug.With two clear positions of two slits, 10,11 corresponding switch base bottom surfaces on fix two upright spring metal intermediate plates 8,9 respectively so that can and realize that from the plug that slit 10,11 inserts electrical equipment connects.Lead-out wire 9 electrical communication of intermediate plate 8 and pulling switch, promptly a phase line with electrical network is communicated with, and for example intermediate plate 8 can directly be fixed on the pulling switch lead-out wire contact screw; 9 of another intermediate plates link to each other with another phase line of electrical network, thus the on off operating mode that can utilize pulling switch control socket (8,9) to power on.Sentence is talked about, and is the function that pulling switch has increased socket.

As for the other parts of pulling switch, then identical with existing pulling switch.Improvement of the present invention concentrates on the configuration aspects of pulling switch base.Therefore, the other parts for pulling switch are not explained in detail here.

Pulling switch of the present utility model can utilize the ready-made finished product transformation of the way, also die sinking tool production and processing again.

This pulling switch that has socket has increased great convenience for the user, is particularly suitable for the present rural area situation of China.If increase electrical appliance temporarily, air blast for example, as long as simply the plug of electrical appliance is inserted on the pulling switch base, not only easy but also safety.

Claims (2)

1, a kind of pulling switch that has the two-phase socket, comprise switch enclosure cover, base and be fixed on the disk of cranking arm, transfer, stage clip, first contact and second contact on the base upper surface, when swing is cranked arm in the backguy drive, realize the switching of two contacts by switching disk and stage clip, it is characterized in that being provided with on the sidewall of said base two parallel slits, the length and width size of two slits and the distance between them will be suitable for the insertion of the inserted sheet of two-pin plug; And fixing two metal intermediate plates respectively on the base end face He on corresponding two positions of said two slits, the position of said intermediate plate and shape will be suitable for electrically contacting with realization with the engagement of two-pin plug inserted sheet.A said intermediate plate and said exit contact are connected, and promptly are connected on the phase line of electrical network, and another phase line of another intermediate plate and electrical network links to each other.

2, pulling switch as claimed in claim 1 is characterized in that a said intermediate plate directly is fixed on the fixed screw of said exit contact.
