Description

Integral protective cover of starter Technical Field The invention relates to the field of electrical equipment of internal combustion engines, in particular to an integral starter protective cover. Background The internal combustion engine needs to provide initial kinetic energy when the internal combustion engine is started through the starter, the electric energy of the storage battery drives the driving gear of the starter to produce mechanical motion, the internal mechanism of the starter drives the driving gear to be meshed into the flywheel gear ring to drive the internal combustion engine to work, after the internal combustion engine is started smoothly, the starter is automatically disconnected to complete a starting process, the starter is used as a key component for starting the internal combustion engine, the quality of the starter is crucial, but the starter wiring terminal needs to be connected with a power supply and cannot be completely sealed, so that special attention is paid to protection in the use process, and the starter is arranged at a lower position of the internal combustion engine and works in severe environments of greasy dirt, muddy water, dust and multiple impurities, the wiring terminal is exposed outside and is most prone to be corroded and oxidized by muddy water and greasy dirt, contact resistance is increased, starting is poor, foreign matter accumulation causes that the starter cannot effectively dissipate heat, the starter is burnt for a long time, and even safety accidents such as short circuit and fire are initiated under extreme conditions. Currently, most starters rely solely on simple rubber bushings or do not make any protection, which results in a high failure rate of the starter. Disclosure of Invention The invention aims to provide an integral starter protective cover so as to solve the problem that the existing starter is easily affected by the outside. In order to solve the problems, the invention adopts the following technical means: An integral starter protective cover is made of elastic insulating materials, a cavity is arranged in the starter protective cover body, and the shape of the cavity is matched with the outline of a starter; The cover body is provided with a binding post hole, the binding post hole comprises an S-terminal binding post hole and a B+ terminal binding post hole, and the hole positions of the binding post hole are aligned with the positions of the S-terminal binding post and the B+ terminal binding post of the starter respectively. Preferably, the elastic insulating material is nitrile rubber. Further, the cover body is integrally formed, and the cavity is of a continuous structure and is seamless. Furthermore, the cover body is provided with at least one mounting hole, and the mounting hole is of a sinking platform hole structure and is used for accommodating a fastener. Furthermore, the mounting hole is positioned on the side wall or the top of the cover body, and the hole position corresponds to a fixed point on the starter body. Furthermore, the bottom of the cover body is provided with a sealing edge with an annular flange structure, and the sealing edge extends along the edge of the cover body to form a continuous interface with the contact surface of the starter shell. Furthermore, the outer wall of the cover body is provided with annular reinforcing ribs, and the reinforcing ribs are raised stripes and are uniformly distributed on the surface of the cover body. Further, the reinforcing ribs vertically extend from top to bottom. The invention has the following beneficial effects in the using process: The nitrile rubber is integrally formed, the insulation performance, the oil resistance, the elasticity and the ageing resistance are particularly good, the structure is simple, the installation is convenient, the sealing is reliable and effective, and the scheme application range is wide. The integral protective cover can ensure that the starter is in a dry working environment, and reduce the fault phenomenon of ablation and short circuit of the starter. The integral protective cover can greatly reduce the failure rate of the starter and improve the reliability and safety.
