Abstract
The utility model discloses a bidirectional anti-rotation gasket applied to an electromagnetic switch. The bidirectional anti-rotation gasket comprises a gasket body (1), wherein the gasket body (1) is provided with a center hole (2) allowing a bolt to pass through, the gasket body (1) is further provided with a plurality of limit claws (3) for limiting the position of a wire harness, the limit claw (3) is L-shaped, one side of the L-shaped limit claw (3) is located at the same plane with the gasket body (1), and the limit claw (3) and the gasket body (1) are of an integral structure. The bidirectional anti-rotation gasket applied to the electromagnetic switch with the structure disclosed by the utility model restricts clockwise and anticlockwise displacement of the wire harness through fixing the wire harness between two bent limit claws, and ensures normal operation of a motor.
Description
Technical field
The utility model relates to a kind of two-way anti-rotation pad for electromagnetic switch.
Background technology
Electromagnetic switch is called control device in starter (DC motor, transmission engaging structure, control device) three large building blocks, its effect be control driven wheel with the engagement of engine flywheel gear ring with separated, and control connection and the cut-out of motor circuit.
Electromagnetic switch is mainly comprised of sucking coil, hold-in winding, movable core, back-moving spring, contact bolt, contact chip etc.Its groundwork process is: as shown in Figure of description 1, after ignitor switch closure, the electric current of hold-in winding flows into direct bonding after coil through the first terminal, the electric current of sucking coil also flows into through the first terminal, but direct bonding after coil, but bonding again after the magnet exciting coil of inflow motor and armature (flowing directly into armature for permanent magnet motor).After two coil electricities, produce stronger electromagnetic force, overcoming back-moving spring power moves movable core, by shift fork, driven wheel is transferred to flywheel ring gear and meshed on the one hand, promote on the other hand contact chip and shift to the contact of the second terminal and motor terminal, after driven wheel and flywheel ring gear engagement, contact chip, by two contactings, makes motor energising running.Before driven wheel enters engagement, owing to having passed through motor through the electric current of sucking coil, so motor can be under the effect of this electric current slow circumvolve so that the engagement of driven wheel and flywheel.After two binding post contactings, the electric current of storage battery directly enters motor by main contacts and contact chip, is that motor enters normal operation, now passes through the circuit of sucking coil by short circuit.Therefore, in sucking coil, no current passes through, and the on-position of main contacts maintains by hold-in winding.After engine start, cut off start-up circuit, hold-in winding power-off, under the effect of back-moving spring, movable core reposition, has cut off the circuit of motor, also makes driven wheel depart from and mesh with flywheel ring gear simultaneously.
The first terminal is connected with additional power source with wire harness by binding post respectively with the second terminal, motor terminal is connected with motor with brush holder brush pigtail by binding post, at wire harness terminals, be enclosed within on binding post with in the process of nut check, wire harness is easily along with the direction rotation of nut check, or cause the fixing of wire harness position because of extraneous reason, thereby cause motor short circuit, affect the normal operation of motor.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of two-way anti-rotation pad for electromagnetic switch for problems of the prior art, its objective is by wire harness being fixed between two position-limited claws of folding up, clockwise and the counterclockwise displacement of restriction wire harness, guarantees the normal operation of motor.
To be this kind comprise shim body for the two-way anti-rotation pad of electromagnetic switch to the technical solution of the utility model, and described shim body is provided with holds the centre bore that bolt passes, and is also provided with the position-limited claw of several restriction wire harness positions in described shim body.
Described position-limited claw is L-type, and wherein limit and the shim body of L-type position-limited claw are positioned at same level.
Described position-limited claw and the shim body structure that is formed in one.
Relation between position-limited claw and shim body can also be, described position-limited claw and shim body are identical material, and described position-limited claw and shim body are welded as a whole.
This kind with said structure for the two-way anti-rotation pad of electromagnetic switch by wire harness being fixed between two position-limited claws of folding up, the clockwise and counterclockwise displacement of restriction wire harness, the normal operation of assurance motor.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is electrical schematic diagram of the present utility model.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is use state diagram of the present utility model.
In Fig. 1-3,1: shim body; 2: centre bore; 3: position-limited claw; 4: the first terminal; 5: the second terminals.
Embodiment
Fig. 1 is electrical schematic diagram of the present utility model, the first terminal 4 is connected with additional power source with wire harness by binding post respectively with the second terminal 5, motor terminal is connected with motor with brush holder brush pigtail by binding post, at wire harness terminals, be enclosed within on binding post with in the process of nut check, wire harness is easily along with the direction rotation of nut check, or because extraneous reason causes the unfixing of wire harness position, thereby cause motor short circuit, affect the normal operation of motor.
Fig. 2 be the utility model for the structural representation of the two-way anti-rotation pad of electromagnetic switch, Fig. 3 is use state diagram of the present utility model.From structure shown in Fig. 2 and Fig. 3 in conjunction with, this kind comprises shim body 1 for the two-way anti-rotation pad of electromagnetic switch, described shim body 1 is provided with holds the centre bore 2 that bolt passes, in described shim body 1, be also provided with the position-limited claw 3 of several restriction wire harness positions, position-limited claw, 3 is L-type, and wherein limit and the shim body 1 of L-type position-limited claw 3 are positioned at same level.
Position-limited claw 3 and shim body 1 structure that is formed in one.Relation between position-limited claw 3 and shim body 1 can also be that position-limited claw 3 is identical material with shim body 1, and described position-limited claw 3 is welded as a whole with shim body 1.
This kind with said structure for the two-way anti-rotation pad of electromagnetic switch by wire harness being fixed between two position-limited claws of folding up, the clockwise and counterclockwise displacement of restriction wire harness, the normal operation of assurance motor.
