Abstract

The utility model discloses an electromagnetic switch, which is composed of a coil, an attract sheet, a linkage sheet, a linkage rod, a sheet placing box, a connecting sheet, etc. The attract sheet of the coil moves to make the attract sheet and the linkage sheet drive the linkage rob positioned in the sheet placing box to do impelling movement from front to back, playing the on-off action between a power supply fixed on the upper connecting sheet and an electrical appliance. The electromagnetic switch can be simultaneously connected a plurality of groups of polyphase power supplies, dispensing with using a relay. The utility model has the advantages of simple structure, small size.

Description

Electromagnet switch

The utility model relates to a kind of electromagnetic switch, and particularly a kind of polyphase source that can connect array simultaneously need not the electromagnetic switch that is applicable to production in enormous quantities of other distribution.

General industry distribution of the prior art, need because of operating mode, usually need one to the homophase of array or heterogeneous power supply for use, so need to adopt a switch that power pack is linked up, it is moved simultaneously, and the general switch employing of using has a starting switch and a shutdown switch, and cooperation is formed with several relays, finish connection with wiring mode between this three, so that when switch closure startup work, allow power pack move simultaneously.But there are many shortcomings in this set.For example owing to starting switch, when shutdown switch is combined with multi-group power again, promptly need use a plurality of relays, and all adopt the wiring mode connection therebetween, so not only the high volume of cost is also quite huge.Wiring mode adopts and pegs graft or welding in addition, often causes wiring error, particularly under the situation of many assembly electricity, all brings puzzlement for assembling and maintenance.And general start and stop switch all adopts the press-contacting type switch, and the cost of this type of switch is also more than general switch costliness, to whole cost is improved.Also have switching device of the prior art, no matter adopt welding manner or inserting mode, must carry out with manual type, and can't reduce the complexity of circuit, so can't realize producing in enormous quantities.

The purpose of this utility model promptly is to overcome above-mentioned deficiency of the prior art, provides to connect the different power supply of array simultaneously, and only needs to use the power line of power supply to weld promptly to finish distribution on contact pin, and need not to re-use relay.Overall volume is little, and each assembly all can be one-body molded, is fit to a kind of electromagentic switching apparatus that mass-produced cost is low and have good result of use.

The foregoing invention purpose is achieved through the following technical solutions.This electromagnetic switch is by coil, adhesive sheet, double-action plate and put film magazine etc. and partly form, and it is characterized in that describedly putting that device has trace and contact pin in the film magazine.

Just design of the present invention is further described below with reference to accompanying drawing according to a most preferred embodiment of the present utility model.

Fig. 4 is the three-dimensional cutaway view of trace in Fig. 2 device.

Fig. 5 is in schematic diagram on the open position for Fig. 2 device.

The schematic diagram that Fig. 6 is in the close position for Fig. 2 device.

Fig. 7 is the assembling schematic diagram of Fig. 2 device.

A kind of electromagentic switching apparatus mainly includes coil 10, adhesive sheet 13,14, and double-action plate 21 is put film magazine 22, trace 25 and upper splicing 28.Have isolated sheet 12 on the coil, upward isolated sheet 12 tops are provided with joint fastener 15 and slot 16, and joint fastener 15 can engage with the prominent contact 17 of coil 10 tops and be communicated with.Slot can plug a double-action plate 21, and the side of adhesive sheet 13 is provided with groove 19 and spring 18.Coil 10 is loaded on the base 11.The outside of the long flanging of base 11 is provided with a spring 20, and the upper end is provided with groove 19, can engage with the groove 19 of adhesive sheet 13 whereby, and installing spring 18 on spring 20 can make and do adhesive and the action that separates again.Putting film magazine 22 is the box body of a hollow, and its inside can be provided with a plurality of shims 26 and inserted slot 27, but plug-in mounting upper splicing 28 and trace 25 whereby.Upper splicing 28 can be the sheet metal of strip, and the one side end is provided with to insert puts 30 and block point 32 admittedly, can be fixed when insertion inserted slot 27.Trace 25 is illustrated in figure 4 as a rectangular body of rod, and its top and both sides offer several holes, and the inboard is provided with puts spring groove 38 with device spring 36.The front end of spring 36 along laterally being equiped with low splicing 29, can make concavo-convexly respectively on the two sides of this low splicing 29, can make it place the top of spring groove whereby and catch on both sides, and stay contact pin and make its promotion before and after doing together with the spring clamping.The top end of low splicing 29 also is provided with little lug, can engage fully with the prominent contact 31 of upper splicing 28 whereby.The periphery of putting film magazine 22 is provided with screwed hole 35, can be fashionable with screw 34 lockings with the lid cover.Putting film magazine 22 can the screw mode fix with base 11.Put between film magazine 22 and the coil 10 double-action plate 21 be housed, its front end be provided with breach 23 can with the folder on trace 25 tops because of put 37 collude close fixing.

After the entire combination, as shown in Figure 5, when adhesive sheet 13,14 up and down not (pressing stop button 42) during adhesive, owing to acting on, tightening of spring 18 make the adhesive sheet up move, and make the double-action plate 21 that is sheathed in the slot 16 toward rising, to making the double-action plate bar that makes A point left side because of leverage, make trace also make low splicing 29 move to the arrow B place and be not on-state thereupon descending toward descending.When pressing startup button 40, last adhesive sheet 13 produces the adhesive action because of the power that presses down with following adhesive sheet 14, the magnetic force that is promptly produced because of coil 10 after the adhesive is adsorbed in down on the adhesive sheet adhesive sheet always, 21 of double-action plates rise the situation that the right side falls because of this adhesive action forms a left side like this, so that low splicing 29 moves on to the arrow C place and engages, make to be welded in the power supply of putting the outer contact pin 28 of film magazine 22 and to connect fully, as shown in Figure 6.If press stop button 42 again, then be returned to the state of Fig. 5.When the power pack of using as need increases, then can and connect, main power line just be welded together to use more multi-group power again it.During assembling, then directly be placed in the outer box 46, row press-fits on the fixed frame 47 again, promptly finishes assembly work as shown in Figure 7.And startup button and stop button can adopt general common switch, to reduce whole cost.

When this electromagentic switching apparatus uses, can be for connecting the different power supply of array simultaneously.The contact pin 28 that in the time of need only assembling the power line of required power supply is welded in the left and right sides respectively gets final product, and need not to re-use relay, and is so volume is little, simple in structure.Each spare part all is formed in one, so be beneficial to a large amount of productions to reduce cost.
