Description
Technical field
The present invention relates to a kind of low-voltage switches box, particularly a kind of airtight low-voltage switches box with explosion prevention function.
Background technology
For low-voltage switches, the general employing mode such as pulled, spurred or press and operate, and makes the contact break-make in the circuit, reaches the purpose that is switched on or switched off power supply.These switches not only simply but also practical but are restricted when using in the down-hole that requirement of explosion proof is arranged.The mains switch that utilizes the characteristic of magnetic and design also has at present, as Chinese patent application number be 88204746 " magnetic force insurance mains switch ", Chinese patent application number is 892057028 " mains switch ", and Chinese patent application number is 902063686 " magnetic control compresses switch ", the method that these several magnetic switches all adopt electromagnet and permanent magnet to combine, be not suitable for using in the down-hole that requirement of explosion proof is arranged, also have complex structure in addition, the problem that manufacturing cost is high.
Summary of the invention
A kind of magnetic provided by the invention moves the power switch box, has solved existing magnetic switch and has been not suitable for using and the high technical problem of complex structure manufacturing cost in the down-hole that requirement of explosion proof is arranged.
The present invention overcomes the above problems by the following technical programs:
A kind of magnetic moves the power switch box, comprise airtight rectangular switch box body, be respectively arranged with left binding post and right binding post in the bottom of switch box body, base plate in the switch box body is provided with the slideway of vertical direction up and down, be movably set with slide at slideway, be set with the inner magnet piece at the middle part of slide, upper end at slide is provided with plug, plug is provided with insulation cushion, be respectively arranged with left power source connecting and right power source connecting at the two ends, the left and right sides of plug, left side power source connecting is electrically connected with left binding post by lead, right power source connecting is electrically connected with right binding post by lead, the top of the slideway in the switch box body is provided with connection circuit socket sheet, is movably set with the outer magnet piece in the top board outside of switch box body, and the corresponding adhesive with the inner magnet piece of outer magnet piece arranges.
Connection circuit socket sheet is provided with elastic bayonet lock.
The present invention comes mobile inner magnet piece by means of the power of attracting each other of magnet itself, makes connecting and disconnecting of the circuit, has conveniently, advantage safe, attractive in appearance, and has the characteristics simple and with low cost of making.Because switch enclosure seals fully, thereby not fire hazardous and blast, particularly suitable is under mine and have the place of dust to use.

Embodiment
A kind of magnetic moves the power switch box, comprise airtight rectangular switch box body 6, be respectively arranged with left binding post 12 and right binding post 13 in the bottom of switch box body 6, base plate in the switch box body 6 is provided with the slideway 8 of vertical direction up and down, be movably set with slide 9 at slideway 8, be set with inner magnet piece 2 at the middle part of slide 9, be provided with plug 3 in the upper end of slide 9, plug 3 is provided with insulation cushion 11, be respectively arranged with left power source connecting 10 and right power source connecting 4 at the two ends, the left and right sides of plug 3, left side power source connecting 10 is electrically connected with left binding post 12 by lead, right power source connecting 4 is electrically connected with right binding post 13 by lead 1, the top of the slideway 8 in switch box body 6 is provided with connection circuit socket sheet 14, the top board outside at switch box body 6 is movably set with outer magnet piece 7, and outer magnet piece 7 arranges with the 2 corresponding adhesives of inner magnet piece.
Connection circuit socket sheet 14 is provided with elastic bayonet lock 5.
The outer magnet piece 7 of a permanent magnetism is set outside the switch box body 6 of sealing, about about 1000 Gausses of magnetic field intensity, the outer magnet piece 7 that mobile box is outer, inner magnet piece 2 in the box will movement therewith, drive upwards operation of slide 9, and with the slideway 8 that is fixed on switch box body 6 tops on connection circuit socket sheet 14 on elastic bayonet lock 5 clampings that arrange, thereby the circuit that is connected respectively on left binding post 12 and the right binding post 13 is connected, realize the purpose of switch closure; When outer magnet piece 7 moves down, drive slide 9 and move downwards, plug 3 breaks away from the elastic bayonet lock 5 that arranges on the connection circuit socket sheet 14, and circuit is disconnected, and realizes the purpose of switch opens.
Housing of the present invention can be used plastic production, and inner magnet piece 2 and outer magnet piece 7 can adopt ferrite or neodymium iron boron, and the metallic conduction sheet is selected copper sheet for use, and insulating barrier can be used plastics.
