Description

Solenoid case of starting motor having retainer integrally

The present invention relates to a solenoid case of a starting motor having a retainer integrally, and more particularly, to have a retainer capable of fixing a switch cover.

As shown in FIG. 1, a starting motor for a vehicle is a device for starting an engine, and is rotated by receiving power from a battery, and a connection pinion on a driver shaft and a ring gear fixed to an outer surface of a flywheel connected to a crankshaft are engaged. It transmits the rotational force of the starting motor to the crankshaft of the engine and serves to start the car.

Referring to the motor starting motor 30 as described above in more detail, the pinion at the end of the shaft 12 of the armature 11 having an armature 11 to provide a rotational force to the inside of the housing 10 (13) is formed.

The pinion 13 is delivered to the end of the drive shaft 17, and the connecting pinion 18 is provided on the drive shaft 17 to connect with the flywheel ring gear of the engine to start the engine.

The connection pinion 18 is slidably moved forward and backward of the drive shaft 17 by an operation lever 21 connected to an operation plunger 20 of an upper solenoid 19 to connect and release with a ring gear. will be.

The actuating plunger 20 of the solenoid 19 pulls the actuating lever 21 by pulling the actuating plunger 20 while the magnetic core is generated by the coil 33 by moving the key to the start position. Engage pinion (18) with ring gear.

The solenoid 19 has a spool 32, a coil 33, an operation plunger 20, a magnet core in a case 35 in which a housing 31 and a right side of the starting motor 30 are fastened with screws 31. A switch cover 37 having a back light and having terminals 36 and 36 'is coupled to the left side of the case 35.

In the related art, in order to fix the switch cover 2 coupled to the left side of the solenoid case 1 as shown in FIG. 4, the end of the switch cover 2 is inserted into the right end of the case 1, and then the case ( Pressing the end of 1) is bent inward to the bent portion 3 is configured to hold the switch cover (2) to secure.

In this case, the bending part 3 is not made in a uniform state in the process of bending the case 1 by pressing, and thus the end of the case 1 is eccentric because the concentricity cannot be maintained.

This affects each of the parts charged into the case (1), thereby providing a cause of deteriorating the solenoid operability, and thus has various problems in direct connection with the performance of the entire starting motor.

Therefore, in the present invention, it is designed to solve the above problems, and the retainer is integrally formed inside the case end of the solenoid so that the switch cover can be fixed without additional bending work.

Hereinafter, the configuration and operation of the present invention will be described with reference to the accompanying drawings.

1 is an overall cross-sectional view of a starting motor for explaining the technology of the present invention, FIG. 2 is an excerpt perspective view of a solenoid case to which the technology of the present invention is applied, and FIG. 3 is a cross-sectional view and a side view of FIG.

A drive shaft 17 having an armature 11 providing a rotational force in the inner side of the housing 10 and receiving a rotational force from a pinion 13 provided at an end of the shaft 12 of the armature 11;

A connection pinion (18) inserted into the driver shaft (17) to connect with the ring gear of the engine and to start the engine while slidingly moving in the axial direction;

The connection pinion 18 includes a spool 32, a coil 33, an actuating plunger 20, and a magnet in a case 35 in which the housing 10 and the right side of the starting motor 30 are fastened by screws 31. In the starting motor 30 to which the switch cover 37 which has a core etc. and which has the terminals 36 and 36 'is operated by the solenoid 19 which has a structure which is coupled to the left side of the case 35;

A plurality of retainers (41, 42) that can press-fit the switch cover 37 to be coupled to the inside of the case 35, the left opening 40 of the solenoid 19 is formed by forming a plurality of radially.

The retainers 41 and 42 press the surface of the case 35 so that one side is in a state connected with the case 35 and the other end so that the end portion 43 protrudes into the case 35. 41 and 42 are pressed to secure the switch cover 37 is coupled to the end 43 of the.

Looking at the working relationship of the present invention configured as described above in the process of assembling the starting motor 30 and the solenoid 19 spool 32, coil 33, the operation plunger 20, A component such as a magnet core is charged, and finally, a switch cover 37 having terminals 36 and 36 'is assembled.

At this time, when the end portion of the switch cover 37 is forcibly coupled to the case 35, the end portions 43 of the retainers 41 and 42 formed to protrude inwardly of the case 35 are expanded to return to their original states. By pressing the switch cover 37 by the force to go to be fixed to the switch cover 37.

As described above, the present invention can maintain the concentricity of the case uniformly because the retainer formed integrally with the case is fixed to the switch cover, thereby eliminating the need for an additional process such as bending of the case, thereby improving the function and performance of the solenoid at the same time. It has such an effect.
