Abstract
The utility model relates to a self locking contactor for saving electric power, which is composed of a dynamic and a static contact heads, a dynamic and a static iron cores, an attracting coil, a spring and a self locking apparatus. The self locking apparatus is composed of a housing, a frame, a sliding sleeve, an upper ratchet wheel, a lower ratchet wheel, a sliding mandrel, etc. Via the self locking apparatus, the breaking and the closing of the dynamic and the static contact heads are achieved to control an electric appliance to work. Because the contactor with novel structure is added with the self locking apparatus, the problem of long time power supply by the attracting coil is solved, the electric power is saved, and the problem of mutual crash of the dynamic and the static contact heads is reduced. The utility model is a novel electric power saving contactor.
Description
The utility model belongs to Electric Traction, and the electric equipment of distribution specifically is a kind of self locking type electricity saving contactor.
In the prior art, contactor generally has straight moving double break dot structure or lever interlock double-breakpoint structure.Straight moving double break dot structure is made up of moving contact, fixed contact, moving iron core, spring, sucking coil, fixed core.When adding rated voltage for the sucking coil be contained on the fixed core, promptly produce electromagnetic force, the reaction force that electromagnetic force overcomes moving upper spring unshakable in one's determination will move adhesive unshakable in one's determination, and the moving moving contact that drives unshakable in one's determination makes it and fixed contact closure.Only when sucking coil cut off the power supply, electromagnetic force disappeared, and moving iron core is got back to original position under the reaction force of spring, and dynamic/static contact separately.This kind structure is because sucking coil is powered the waste much electricity for a long time.Lever interlock double-breakpoint structure is that iron core will move rotation unshakable in one's determination by the effect of lever and become the straight moving of moving contact, and structure is comparatively complicated.
The purpose of this utility model solves the existing in prior technology problem with regard to being, and a kind of novel structure that provides is saved electric energy, and can alleviate the self locking type electricity saving contactor that dynamic/static contact collides mutually.
Below in conjunction with accompanying drawing structure of the present utility model and operation principle are described in detail.

Label declaration:
1, moving contact 2, fixed contact 3, sliding sleeve 4, pawl seat 5, last ratchet 6, bottom ratchet wheel 7, link mandrel 8, spring 9, screw 10, frame 11, moving iron core 12, spring 13, sucking coil 14, fixed core 15,16, pin 17, spline 18, lever
Such as Fig. 1-shown in Figure 5, the straight moving Double-breakpoint contactor of the utility model band self-locking device is by moving contact 1, static contact 2, moving unshakable in one's determination 11, fixed core 14, sucking coil 13, spring 12 and self-locking device form, this self-locking device is by shell, pawl seat (4), frame (10), sliding sleeve (3), upper ratchet (5), bottom ratchet wheel (6), link mandrel (7), spring (8), screw (9), spline (17) forms, the upper cover of link mandrel (7) has pawl seat (4) and upper ratchet (5), bottom ratchet wheel (6), upper ratchet (5) is meshed with bottom ratchet wheel (6), the upper cover of pawl seat (4) has sliding sleeve (3), sliding sleeve (3) is contained on the frame (10), the bottom of sliding sleeve (3) is fixedly connected with moving (11) unshakable in one's determination by pin (15), be provided with spring (12) and sucking coil (13) between moving (11) unshakable in one's determination and the fixed core (14), fixed core (14) links to each other with shell, pawl seat (4), frame (10) is fixedly connected with by screw (9), be provided with spring (8) between link mandrel (7) and the screw (9), also be connected with spline (17) on the pawl seat (4).
Its operation principle is as follows: when adding a pulse voltage for the sucking coil 13 that is contained on the fixed core 14, the electromagnetic force that produces overcomes spring 12,8 active force, adhesive moving unshakable in one's determination 11 drives sliding sleeve 3 makes ratchet 5 promotion bottom ratchet wheels 6 move down certain distance, and rotates an angle. After the pulse, moving unshakable in one's determination 11 drive sliding sleeve 3 resets, because the effect of spring 8 moves upward link mandrel 7 and upper ratchet 5, bottom ratchet wheel 6, link mandrel 7 also moves down with moving contact 1 simultaneously, makes moving contact 1 and static contact 2 closures. After the dead electricity, because bottom ratchet wheel 6 has turned over an angle, spline on the pawl seat 4 17 no longer meshes with spline on the bottom ratchet wheel 6, thereby stops resetting of bottom ratchet wheel 6, and link mandrel 7 can not reset, Thereby guarantee dynamic/static contact 1,2 closure. If make dynamic/static contact 1,2 minutes when opening, add a pulse voltage for again sucking coil 13, make bottom ratchet wheel 6 rotate an angle, at this moment, spline engagement on spline 17 and the bottom ratchet wheel 6, bottom ratchet wheel 6 is return original position under the effect of spring 8 and link mandrel 7, dynamic/static contact 1, opened in 2 minutes.
Fig. 6 is the lever coordinated type contactor construction schematic diagram of the utility model band self-locking device.Different with the straight moving double break point type contactor of band self-locking device is, the bottom of sliding sleeve 3 also can link to each other with an end of lever 18 by pin 15, the other end of lever 18 links to each other with moving unshakable in one's determination 11 by pin, be provided with sucking coil 13 between moving iron core 11 and the fixed core 14, also be connected with spring 12 on the other end of lever 18, the other end of spring 12 links to each other with shell.
This contactor by the effect of moving iron core 11 and transmission levers 18, makes self-locking device produce disjunction and closures to moving contact 1 and fixed contact 2 by to 13 1 pulse voltages of sucking coil, comes control apparatus work.
The utility model novel structure owing to increased self-locking device, has solved the problem of the long-time power supply of sucking coil, and save electric energy greatly, and can alleviate the problem that dynamic/static contact collides mutually, be a kind of novel power saving contactor.
