Abstract
The utility model relates to a pulse self-locking relay. The side of a movable armature iron side is provided with a curved ratchet pawl, the ratchet pawl is movably arranged on a support frame, and the place between the ratchet pawl and the support frame is connected with a reset spring. The place between the ratchet pawl and a contact system is provided with a cam which is supported by the support frame. The cam and a reversing ratchet wheel is connected into a whole. The utility model has advantages that impact prevention and vibration prevention because of the self-lock by the cam, reliable working performance, momentary current supply of the coils of the relay, electrical energy saving, and memory function. The utility model can be widely applied to the automation control device and the control signal circuit.
Description
The utility model belongs to a kind of relay, particularly a kind of pulse machine self-locking electromagnetic intermediate relay.
Existing auxiliary relay is behind the contact system closing of circuit, and relay coil does not cut off the power supply, thereby consume electric power is many, because it does not have reliable latch-up structure, therefore is afraid of shock and vibration simultaneously, and the serviceability reliability is relatively poor.
The purpose of this utility model provides a kind of novel pulse self-locking auxiliary relay, and operating state is by mechanical caging, shock-resistant and vibration, and dependable performance, relay coil moment power supply can be saved a large amount of electric energy.
The purpose of this utility model is achieved in that on the mobile armature side and is provided with curved ratchet, the ratchet activity is assembled on the support, connect back-moving spring between the two, the cam by bracket supports is set between ratchet and contact system, cam and commutation ratchet combine as a whole.
The utility model has the advantages that: because moving contact is not afraid of shock and vibration, reliable working performance by the cam self-locking, the instantaneous power supply of relay coil, can save a large amount of electric energy, and possess memory function is arranged, can be widely used in automatic control device and the control signal circuit.
Below in conjunction with accompanying drawing the utility model embodiment is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
See Fig. 1,2, concrete structure of the present utility model is as follows: assembling magnetizing coil 10 on base 7, and a side of magnetizing coil 10 has the yoke 9 that can play magnetic conduction and supporting role, movable " " type mobile armature 8 that connects on it; Two moving contacts 4 and four fixed contacts 3 of assembling contact system on the base 7.Can increase the fixed contact 3 of moving contact 4 quantity and diploidy number amount as required.Affixed support 2 on the base 7, the curved ratchet 6 of movable assembling connects back-moving spring 1 between the two on the support 2.The upper end of support 2 is between contact system and curved ratchet 6, and connecting rotating cam 5 and turn to ratchet 11, two ends by axle is that cam 5, centre combine as a whole for ratchet 11.The working surface of end in contact cam 5 on the moving contact 4, ratchet 6 contacts turn on the gear teeth of ratchet 11, and ratchet 12 can only one-directional rotation.
Operation principle: after the magnetizing coil 10 of relay receives the pulse voltage of input, just producing magnetic flux makes mobile armature 8 be moved by magnetic attraction, promote the elasticity masterpiece mechanical movement that curved ratchet 6 overcomes back-moving spring 1, curved ratchet 6 promotes ratchet 11 and drives the cam rotation certain angle, moving contact 4 and fixed contact 3 on off operating mode generation conversion.10 outages of relay magnetizing coil, moving contact 4 is by cam 5 self-lockings.
