Description

A kind of time pulse relay

Relay is extensive use of at electronic technology field and automation field.Existing relay is provided with normal battle and normally closed point.When needs are often made war adhesive, need be in coil galvanization, and need to keep always.Such one is that the power consumption of coil is big, caloric value is big, and corresponding volume is also big.The 2nd, when circuit was interfered or occur being interrupted power failure, control can produce misoperation.

The present invention relates to a kind of time pulse relay.It comprises: coil, stator, slide plate, magnet, bar of magnetic material, diode etc.

The object of the present invention is to provide a kind of time pulse relay, its little power consumption has the state memorization function, is suitable for various control circuits.

Technical scheme of the present invention is: a kind of time pulse relay comprises: shell, movement.Movement is made up of coil, stator, slide plate, magnet, bar of magnetic material, diode etc.Slide plate is metal material and is placed in the middle of two coils, respectively draw a lead on the stator and connect the Be Controlled object, coil has two, and symmetry is placed on both sides, and it is by two signal input end, when adding a pulse control voltage a control input end, slide plate is to a side shifting, and moves to a position, and slide plate links to each other with two stators on being fixed on this coil end face, pulse voltage finishes, and its location status does not change.When adding a pulse control voltage from another input, slide plate moves to opposite side again, and moves to a position, and slide plate links to each other with two stators on being fixed on another coil end face, end-of-pulsing, and its location status does not change yet.

Further specify the utility model below by accompanying drawing and by executing example:

Fig. 1, time pulse relay fundamental diagram.

Fig. 2, slide vane structure schematic diagram.

Embodiment: as shown in Figure 1, coil is placed on both sides, bar of magnetic material E1, an E2 are respectively inserted in the coil axes centre, stator G1, G2, G3, G4 are the metallic conduction material, are fixed on the end face of coil symmetrically, and respectively draw a lead Q, Q ＇, P, P ＇, slide plate H also is the metallic conduction material, electromagnet M of its center panel, and be placed in the middle of two coils, and can slide.Two coils are respectively drawn two lead-in wires, and their different name end is connected, and at each point of contact, draw a lead and are connected a diode.The diode lead that the lead that point of contact Y draws is connected with point of contact X constitutes a pulse voltage input terminal A-A ＇, and the lead-in wire of the diode that the lead that tie point X draws is connected with point of contact Y constitutes another pulse voltage input terminal B-B ＇.When from pulse voltage of an input terminal (for example A-A ＇) input, two the direction of the winding current are opposite, and the magnetic direction that hub of a spool produces is also opposite.Because the magnet of slide plate upper mounting clamp simultaneously is the N utmost point, one side is the S utmost point, so the magnetic field that coil produces produces thrust to one of slide plate, one produces gravitation, but the direction unanimity of two power, promptly make slide plate to a side shifting jointly, if this moment, slide plate moves to coil L2 direction, when moving to coil L2, slide plate engages with two stator G3, G4, and P, P ＇ are communicated with, after pulse voltage finishes, because the magnet on the slide plate and the graviational interaction of the magnetic material in the coil, slide plate still engages securely with two stators, and promptly location status is constant, that is has memory function.In like manner, when from pulse voltage of B-B ＇ end adding, slide plate leaves coil L2 and moves to coil L1 direction, finally is fixed up at coil L1 place, and slide plate engages with two stator G1, G2, and Q, Q ＇ are communicated with, and stator G3, G4 disconnect at this moment.Two diodes are the senses of current of determining two inputs.
