Abstract
The invention discloses a waterproof sealing device for a motor casing outlet. The waterproof sealing device for the motor casing outlet comprises a shell, a screwed joint, a nut and a seal ring, wherein the shell is provided with a threaded hole; one end of the screwed joint is provided with a thread which is matched with the threaded hole; the nut is matched with the other end of the screwed joint; the seal ring is arranged at one side of the screwed joint matched with the threaded hole; both of the screwed joint and the nut are provided with a through hole; a motor lead can penetrate through the through hole and protrude; the shell is provided with the threaded hole, and the screwed joint is matched with the shell through a thread; the other end of the screwed joint is screwed up by the nut, and the seal ring is arranged at one end of the screwed joint contacted with the shell. Therefore, the tightness of the screwed joint and the threaded hole can be guaranteed, the motor lead can be conveniently led out, the structure is simple, and the waterproof sealing effect is good, so that water can be prevented from entering a motor, thus the service life of the motor and the vehicle performance reliability can be improved.
Description
Technical field
The invention belongs to the building block of a kind of plastic packaging motor, especially relate to a kind of motor case and go out
Line mouth waterproof seal.
Background technology
Conventional electric vehicle motor lead-out wire seals at casing line outlet position, mainly by lead-out wire
Rubber injection mold head and the compression fit of motor case line outlet, and then reach the waterproof sealing work at this position
With.This sealing means has in practice been verified that, owing to motor is in vanning transport and car load assembling process,
Motor lead-out wire is easily considered dilatory and causes rubber injection mold head to deform, injecting head and casing wire hole knot
Closing position can get loose, waterproof effect will lose efficacy, and leverages service life of motor and car load
Performance.
Summary of the invention
It is an object of the invention to provide a kind of motor case line outlet waterproof seal, it is possible to solve
At least one in the problems referred to above.
According to an aspect of the invention, it is provided a kind of motor case line outlet waterproof seal,
Including housing, nipple, nut and sealing ring, housing is provided with screwed hole, one end of nipple
Being provided with screw thread, close with corresponding threaded holes, nut matches with the other end of nipple, and sealing ring sets
In the side that nipple coordinates with screwed hole, nipple and nut are equipped with through hole.
The invention has the beneficial effects as follows: nipple and nut are equipped with through hole, thus, motor down-lead
Can stretch out through this through hole；Being provided with screwed hole on housing, nipple is joined by screw thread with housing
Closing, the other end of nipple tightened by nut, and nipple one end with housing contact position
It is provided with sealing ring.Thus, it is possible to ensure the sealing of nipple and screwed hole, and motor is facilitated to draw
The extraction of line, simple in construction, waterproof sealing effect is good, thus prevents water to enter into motor, and then
Improve the service life of motor and the performance reliability of car load.
In some embodiments, motor case line outlet waterproof seal also includes sealant layer,
Sealant layer is located between screwed hole and nipple.Thus, it is provided with sealant layer, can be further
Improve nipple and coordinate the sealing at place with screwed hole.
In some embodiments, the other end of nipple is tapered, nipple other end end face
External diameter minimum.Thus, it is possible to improve the compactness that nipple coordinates with nut.
In some embodiments, nut coordinates place tapered with nipple.Thus, taper is passed through
Structural lock tight fit, improves the compactness of the cooperation of nut and nipple, and ensure will lead-in wire simultaneously
It is fixed.
In some embodiments, one end of nipple is beyond the inwall of housing.Thus, it is possible to increase
Add the length of fit of nipple and screwed hole, improve waterproof sealing performance further, lead-in wire is fixed.
Accompanying drawing explanation
Fig. 1 is the structural representation of the motor case line outlet waterproof seal of the present invention；
Fig. 2 is the structure for amplifying schematic diagram of part A in Fig. 1.
Detailed description of the invention
The present invention is further detailed explanation below in conjunction with the accompanying drawings.
See figures.1.and.2: motor case line outlet waterproof seal, connect including housing 1, screw thread
2, nut 3 and sealing ring 4, the outer surface of housing 1 offers screwed hole, the one of nipple 2
End is provided with screw thread, closes with corresponding threaded holes, and nut 3 matches with the other end of nipple 2, close
Seal 4 is located at the side that nipple 2 coordinates with screwed hole, nipple 2 and nut 3 and is equipped with
Through hole 5.In use, it is internal that motor 20 is arranged on housing 1, and motor down-lead 10 is through screw thread
The through hole 5 of joint 2 and nut 3 passes, and is gone between with the realization that coordinates of screwed hole by nipple 2
The sealing of 10 line outlets.
One end of nipple 2 and screwed hole threaded engagement, and the end face of nipple 2 one end stretches into
And beyond the inwall of housing 1 so that the length of fit of nipple 2 and screwed hole and the length of screwed hole
Spend equal, it is ensured that sealing, good water-proof effect.
In order to be further ensured that waterproof sealing performance, nipple 2 is provided with protruding 21, protruding 21 and is positioned at
The outside that nipple 2 closes with corresponding threaded holes, and the end face of protruding 21 abuts against with housing 1, close
Seal 4, between protruding 21 and housing 1, prevents water from the abutting end of nipple 2 with screwed hole
Surface current enters, it is ensured that sealing.
The motor case line outlet waterproof seal of the present invention also includes sealant layer 6, sealant layer 6
It is located between screwed hole and nipple 2.Nipple 2 in an assembling process, is screwed into by this device
To screwed hole, at both cooperations, inject fluid sealant, form sealant layer 6 after condensation, prevent water
Entered with the screwed hole place of cooperation from nipple 2.
The other end of nipple 2 is tapered, and the external diameter of nipple 2 other end end face is minimum；Spiral shell
Cap 3 coordinates place tapered with nipple 2.Nipple 2 uses pyramidal structure with both nuts 3
Locking coordinates so that during lead-in wire 10 passes, the internal diameter of through hole 5 is gradually reduced, and then realizes logical
The hole 5 fixation to lead-in wire 10.
Use the motor case line outlet waterproof seal of the present invention, can be by through hole 5 by motor
Lead-in wire 10 fix, and connect by 5 outlets that realize going between of the structures such as nipple 2 and sealant layer 6
The waterproof seal of mouth, simple in construction, low cost of manufacture, install easy to operate；Good water-proof effect,
Substantially increase service life and the reliability of vehicle performance of motor 20 in housing 1.
Above-described is only the preferred embodiment of the present invention, it is noted that general for this area
For logical technical staff, without departing from the concept of the premise of the invention, it is also possible to make some changes
Shape and improvement, these broadly fall into protection scope of the present invention.
