Abstract
The utility model relates to a rolling ball contact switch which is composed of a support frame, a contact piece, a conduction rolling ball, a wiring terminal and a conducting wire. The utility model has the advantages of simple structure, high safety, long service life, low cost, wide operating range, etc. The utility model is suitable for instruments and domestic appliances which need tilting prevention.
Description
The utility model relates to a kind of contact switch, particularly relates to a kind of spin contact switch.
Employed contact switch in existing instrument, instrument and the household electrical appliance, its connecting point position is fixed mostly, and the break-make of switch can not reflect the residing location status of switch.Can reflect the mercoid switch of its location status by the break-make of switch, the scope of its change in location is very little, and mercoid switch mercury frangible, that overflow is poisonous, cost is higher.
The purpose of this utility model provides a kind of spin contact switch, and the break-make of this spin contact switch can reflect in a big way that switch departs from the state of horizontal level.
The utility model is to realize by following technical scheme.In the bottom of cylindrical shell shape insulating support (11) supporting bracket (17) is arranged, have for the hole (14) that usefulness is installed in the bottom of cylindrical shell shape insulating support (11), (19), central authorities in supporting bracket (17) have hole (8), the periphery of going up in the hole (8) in supporting bracket (17) has the installing hole (12) that conduction garden awl part (5) is installed, (16), hole (12), (16) in same garden on week, go up in the hole (12) in supporting bracket (17), (16) periphery has the garden connected in star (13) that conduction garden tube (3) is installed, and goes up in supporting bracket (17) and has hole (18) in the periphery of garden connected in star (13).Between the top of the top of hole (12), (16) and hole (8) the garden conical surface (6) is arranged, the bus of the garden conical surface (6) and the angle between the axis are α.The conduction garden awl part (5) that tapering is identical with the garden conical surface (6) is installed on the garden conical surface (6) of supporting bracket (17), and during installation, the pin of awl part (5) garden, conduction garden on week is with mode patchhole (12), (16) of interference fit.Conduction garden awl part (5) is gone up and is placed conduction spin (7).Insulating lid (4) is installed in the upper end of cylindrical shell shape insulating support (11) by bonding method, also can install with screw.The inboard of insulating lid (4) has garden connected in star (2) coaxial with garden connected in star (13) and that radius equates, goes up the periphery of garden connected in star (2) at insulating lid (4) separated conductive connector (1), (9) are installed.The top and bottom of conduction garden tube (3) embed respectively in the garden connected in star (2) and the garden connected in star (13) on the supporting bracket (17) on the insulating lid (4), and lid (4) just in time will conduct electricity garden tube (3) and be pressed on the supporting bracket (17).Lead (10) connects conductive connector (9) and conduction garden tube (3), and lead (15) passes hole (18) and connects conductive connector (1) and conduction garden awl part (5).
When the spin contact switch was horizontal, conduction spin (7) was because deadweight is in the central authorities of conduction garden awl part (5), and the spin contact switch is off-state.When the spin contact switch surpass at the angle φ that any direction of horizontal plane tilts (90 °-α) time, conduction spin (7) will contact along the incline direction rolling and with conduction garden tube (3), as long as the diameter of spin (7) is greater than the garden week radius and the radius of conduction garden tube (3) poor of conduction garden awl part (5), the spin contact switch just is on-state.When the spin contact switch returned to horizontal level, conduction spin (7) was got back to the central authorities of conduction garden awl part (5) again, and the spin contact switch recovers off-state.So the break-make of spin contact switch can reflect that it departs from the state of horizontal level.Because the α angle can be greater than 0 °, less than selecting arbitrarily in 90 ° of scopes, so the spin contact switch has the very wide scope of application, the α angle is big more, and it is sensitive more that the spin contact switch departs from the level reaction to it.
The utility model is simple in structure, and is safe and reliable, and the life-span is long, and cost is low, and service area is in a big way arranged.
Fig. 1 is the structural representation of spin contact switch.
The cylindrical shell of the cylindrical shell shape insulating support (11) of spin contact switch is a garden shape, also can be square or polygonal.Insulating support (11) and insulating lid (4) are used the ambroin injection mo(u)lding, also can make with other insulating material.The spin contact switch is installed on the instrument and equipment by hole (14), (19), also can adopt bonding method to be installed on the instrument and equipment.The perforate (8) of supporting bracket (17) central authorities is of moderate size, and bores being connected of part (5) to make things convenient for lead (15) with the conduction garden.Conduction garden awl part (5) is installed on the supporting bracket (17) by the mode that two pins of its garden on week are pressed into hole (12), (16), also can when insulating support (11) injection mo(u)lding conduction garden awl part (5) be fixed on the supporting bracket (17).Conductive connector (1), (9) are installed on the insulating lid (4) with interference fit, also can be with binding post (1) when insulating lid (4) injection mo(u)lding, and (9) are fixed on the lid (4).Lead (10), (15) and conductive connector (1), (9), conduction garden awl part (5), welding is adopted in the connection of conduction garden tube (3), also can adopt riveted joint or other connected mode.Conductive connector (1), (9), conduction garden tube (3), conduction garden awl part (5), conduction spin (7) is made with brass, and is silver-plated again, also can make with other electric conducting material.
Go up in the inboard of insulating lid (4) and supporting bracket (17) on the position of conduction garden awl part (5) symmetry another conduction garden awl part is installed, this just can make the spin contact switch still be in on-state during greater than 90 ° in inclination angle phi.
