Problems solved by technology

One of the defects of this structure is that after PG components are assembled, there is a gap in the position of the slot, and the anti-vibration rubber ring has no fixed effect on the power line of the PG component. This installation method will make the gap between the power line and the plastic stator and end cover A gap is formed at the place where the gap is matched, so that external tiny organisms and sundries can enter the interior of the plastic-sealed stator through the gap, which is likely to cause quality problems such as motor jamming, which seriously affects the service life of the motor.

Embodiment 1

[0022] Such as Figure 1~4 As shown, a plastic-sealed motor with sealing performance includes a plastic-sealed motor body and shockproof rubber rings 3 installed at both ends of the plastic-sealed motor body. The plastic-sealed motor body includes a stator assembly and a plastic casing 1 around the stator assembly. The end surface of the plastic casing 1 A wire groove 11 is provided, and the power cord 41 of the PG component 4 is drawn out from the wire outlet on the plastic casing 1 and nested in the wire groove 11. A sealing ring 42 is set on the power wire 41, and the sealing ring 42 is set in the wire groove 11. The bottom of the shockproof rubber ring 3 is provided with a bump 32 that compresses the seal ring 42 in the wire groove 11, and the bump 32 at the bottom of the shockproof rubber ring 3 is pressed against the seal ring 42 located in the wire groove 11, so that the wire groove 11, The sealing ring 42 sleeved on the power cord 41 and the protrusion 32 are squeezed ...

Embodiment 2

[0028] refer to Figure 1~3 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that one side of the sealing ring 42 is provided with an opening, and the sealing ring 42 with one side opening can be locked at any time. Putting it on the power cord 41 is sufficient to reduce the time for the sealing ring 42 to be placed on the power cord 41 when the power cord 31 is too long, thereby optimizing the installation process.

Abstract

The invention relates to the technical field of plastic package motors, in particular to a plastic package motor with sealing property. A seal ring sleeves a power line and is arranged in a line slot;a bump for compressing the seal ring into the line slot is arranged at the bottom of a shock-proof rubber ring; the seal ring sleeves the power line and is located in the line slot; a bottom plate with the bump is arranged at the bottom of the shock-proof rubber ring; the bump at the bottom of the shock-proof rubber ring is compressed on the seal ring located in the line slot, so that the line slot, the seal ring sleeving the power line and the bump are mutually extruded, the spare space in the line slot is reduced and a gap in the line slot is reduced, thereby preventing external microorganisms and impurities from entering the inside of the plastic package motor and solving the problem that the gap is formed in the matched part among a traditional power line, a plastic package stator andan end cover and the external microorganisms and impurities can enter the inside of the plastic package stator from the gap to cause locking of the motor.

Description

Technical field: [0001] The invention relates to the technical field of plastic-sealed motors, in particular to a plastic-sealed motor with sealing performance. Background technique: [0002] In the prior art, the installation structure of PG components and the installation structure of shockproof rubber ring are as attached image 3 , 6 7. As shown in 7: Install the PG component on the plastic-sealed stator, then press and fix the PG component on the plastic-sealed stator through the end cover, and at the same time, the power line of the PG component passes through the wire slot provided on the plastic-sealed stator to go out of the plastic-sealed stator , The anti-vibration rubber ring is installed and fixed on the end cover. One of the defects of this structure is that after PG components are assembled, there is a gap in the position of the slot, and the anti-vibration rubber ring has no fixed effect on the power line of the PG component. This installation method will ma...
