Embodiment
The utility model comprises the housing 8 that embeds four terminal bolts 5, contact block 14 and loam cake 9 that can the turn certain angle, and housing 8 tops are provided with loam cake 9, and are as shown in the figure, and the structural feature of the utility model is following:
Housing 8 is main bodys of structure, and it forms by Reinforced Nylon is plastic injection-moulded, is a reliable insulator.Embed two pairs of terminal bolts 5 that brass is processed on the baseplane of housing 8, the threaded portion of terminal bolt 5 stretches out the control circuit that housing 8 outsides are used to connect switch external.Terminal bolt 5 apical head planes are concordant with housing 8 baseplanes.Described brass terminal bolt 5 is provided with safety guard 3.Can be to being used for direct current drive goat safety switch only with pair of terminal bolt 5; Safety switch for exchanging the three-phase electric point machine then must have two pairs of terminal bolts 5 at least; Contact A and contact B are a pair of; Contact C and contact D are a pair of, and at least two line power circuits to guarantee to cut off three-way AC power can not rotate three phase alternating current motor.
Contact block 14 is injection molded by Reinforced Nylon; There are four cylindrical holes 13 on its top; Respectively packing in the cylindrical hole 13 one is embedded with the copper contact 10 of Agcdo contact, and copper contact 10 is provided with spring 12 in the cylindrical hole 13, and the copper contact 10 of Agcdo contact ejects cylindrical hole 13 by compression spring 12; And brass terminal bolt 5 tops that on housing 8, embed with the pressure roof pressure more than 0.4 kilogram, thereby form the reliable connection of shell outer control circuit.The tail end of contact A and contact B is connected with the line 11 that is flexible coupling, and the tail end of contact C and contact D also is connected with the line 11 that is flexible coupling, so is linked to be a conductor between contact A and contact B, contact C and the contact D.They are connected terminal bolt 5 circuit of correspondence respectively.Every pair of contact 10 is provided with connecting plate 4.When contact block 14 aligned the terminal bolt 5 of 4 housing bottoms, then two pairs of terminal bolt 5 corresponding electrical circuits were connected respectively.Contact block 14 dextrorotations are when terminal bolt 5, and then two pairs of terminal bolt 5 corresponding electrical circuits are disconnected.The contact block 14 1 side centers of being designed to are the hollow shaft 6 of square hole 7, and the two ends of axle 6 are inserted in the hole of housing 8 bottoms and the hole on the loam cake 9 respectively.The square hole 7 of axle 6 cores is used to connect the axle of goat blind patch group; Thus; When hand crank is inserted in goat maintenance, blind patch group axle 14 degree that the maintenance personal stirs under, turn clockwise, 2 or 4 contacts 10 are under contact block 14 drives; Head with terminal bolt 5 disengages respectively, thereby has cut off a pair of or two pairs of control circuits that terminal bolt 5 connects.
Loam cake 9 is used for housing 8 sealing, and contact block 14 is fixed on the position of design, so that contact block 14 flexibility and reliability ground rotary work.
A locking bar 1 that stretches out housing 8 right-hand member sidewalls is housed on the contact block 14; Rectangular recess 2 is arranged on the locking bar 1; Locking bar 1 one ends are provided with extension spring 15; This locking bar 1 groove 2 falls into housing 8 sidewalls in the effect of extension spring 15 after contact block 14 turns clockwise 14 degree, thereby contact block 14 is locked on the position after the rotation.After the maintenance personal works completion; In the time of must goat being returned to the circuit state of a control; The maintenance personal just can lift locking bar 1 and the goat blind patch is lifted 14 degree and just can make safety switch recover normal condition, i.e. lockable goat blind patch, and goat just can recover normal operating conditions.
Because housing 8 is connected whole switch with loam cake 9 and is sealed into one, and contact material employing silver cadmium oxide contact material, contact performance is reliable; The arc extinguishing effect is arranged during charged cut-out switch; The contact contact pressure produces constant pressure, working stability by contact pressure spring 12; Safe and reliable, almost can be non-maintaining.
