Description

The step cycle relay

The utility model relates to a kind of relay, particularly a kind of have latch, handoff functionality, and can circulate and connect the step cycle relays of many groups contact, can be widely used in film, touch-switch and the electronic circuit selection of signal to various electrical equipment, instrument, range, function and to the speed of motor, the control of bulb brightness etc.

Now to connect many group contacts or carry out measurement range selection, electrical micro-machine to take turns to operate all to need to drive the relay or the switch that are connected and carry out its complex structure, cost height, use inconvenience with adding electronic circuit.

The purpose of this utility model is to provide a kind of step cycle relay, can be applied directly in the circuit that needs conversion, selects, and need not increase any stepping latch cicuit, its compact conformation, and cost is low, energy-conservation.

The utility model is achieved in that the step cycle relay is fixed on the base plate by the skeleton that has coil, iron core by yoke and the armature above the yoke constitutes magnetic circuit drive part and operating part form, and operating part pushes away the reset cradle that rolls and is connected with the armature that band is pawled by having, and with drive more than 2 groups and 2 groups, the dynamic and static reed composition of fixed contact.

Below in conjunction with accompanying drawing embodiment of the present utility model is further described.

Be wound with the skeleton (6) of coil (7), pass through hole riveted and fixed on skeleton (6), yoke (4), the base plate (16) on base plate (16) by iron core (5), by coil leading foot (19) draw and armature (10) to constitute the magnetic circuit drive part the same with prior art.

Static contact spring piece (15) is a strip, and there is fixed contact (14) upper end, and the lower end is leading foot (17), and 4 static contact spring pieces (15) are vertically fixed in base plate (16) elongated slot on one side.

Movable contact spring (12) is Shape, upper end have moving contact (13), and 4 movable contact springs in lower end (12) are that a horizontal brace and a leading foot (18) that links to each other is fixed on the base plate (16).

Reset cradle (11) upper end is an inclined-plane, and the ligule sheet on it is pushed down the afterbody of armature (10), the reset mode of holding armature (10), and the middle part is perpendicular to base plate (16), and riveted and fixed is on the ridge in yoke (4) outside.There is the flanging of 90 ° of turnovers both sides, and respectively there is through hole the flanging lower end.One detent (20) is at the inferoanterior of ratchet (2), and the upper end heads on ratchet (2) and prevents revolution, and the lower end is gone up fixing at base plate (16).The horizontal brace of movable contact spring (12) lower end is pushed down in the lower end of reset cradle (11).

Ratchet (2) is the peripheral inclined-plane tooth that 8 five equilibriums are arranged, and cam (1) is a cylinder, and there is the small column (21) of 4 groups of uniform 8 protrusions on the surface, and shape is arranged in the shape of a spiral.Two small columns (21) on the same group differ 180 ° on same periphery, two adjacent small columns differ 45 °.With axle ratchet (2), cam (1) being linked to be holistic pushing away rolls in the through hole that (22) be fixed on reset cradle (11) two flanging lower ends.

One side of armature (10) has a vertical armature arm, and respectively there is a breach relevant position, two edges, lower end, is installed on the top of yoke (4).

The front end of (3) of pawling cooperates with the inclined-plane tooth of ratchet (2), promotes ratchet (2) and rotates, and jagged and ligule sheet in the middle of the rear end is stuck in the breach on the armature arm of armature (10), and pawl (3) are fallen down.

During use, when feeding pulse voltage, coil (7) makes yoke (4), iron core (5) forms magnetic circuit adhesive armature (10) rapidly downwards, close to iron core (5) direction, armature arm on armature this moment (10) also is being with pawl (3) along with moving forward, (3) front end of pawling heads on ratchet (2) and rotates, the cam (1) coaxial with ratchet (2) also rotates as Fig. 2, a, shown in the b, this moment is moving, fixed contact (13), (14) be off-state, when turning to Fig. 2, c, position shown in the d, small column (21) on cam this moment (1) promotes movable contact spring (12) and moves forward, then moving, fixed contact (13), (14) be closure state, after coil (7) pulse voltage, stop power supply, at this moment armature (10) is owing to lose magnetic force, be subjected to the pressure of reset cradle (11) upper end ligule sheet again and reset, pawl simultaneously (3) also under the drive of armature arm, return to the origin-location, and this moment is moving, fixed contact (13), (14) still be closed and latch.When giving coil (7) energising next time, the pawled thrust of (3) of ratchet (2), be rotated further, make the small column (21) on the cam (1) cross the bending part of movable contact spring (12), its dynamic and static contact (13), (14) are disconnected, finished the course of action of 1 group of contact, ratchet (2) is rotated further, small column (21) on the cam (1) promotes movable contact spring (12) and moves forward, and then makes the 2nd group dynamic and static contact (13), (14) be closure state.As mentioned above, whenever give coil (7) energising once, it is logical that ratchet (2) stepping rotary contact just changes a winding, finish make and break process one time, 4 groups of contacts are connected in turn, get back to the 1st group of contacting again after treating that the 4th winding is logical and finishing, so constantly repetitive cycling work is connected in circulation.

The utility model compared with prior art, because this this body structure of relay has the mechanical latching function, institute Not need increasing any latch cicuit that went on foot, can save a lot of electronic components, its compact conformation, volume is little Cost is low, does not just need power supply, not power consumption of static state, very energy-conservation after relay contact latchs. The user Just, only need use various buttons, touch, thin film switch or electronic circuit driving just can work.
