Abstract
A kind of permanent protective property connection box for motor, relates to technical field of motors, and solved is the technical problem improving motor integral protection performance.This rosette includes that box body, the lower end of described box body offer cable entries, and is provided with the wiring sealing gasket of the cable entries covering box body bottom on box body；Being formed with multiple downwardly projecting projection on described wiring sealing gasket, each projection offers the cable-through hole of a up/down perforation, described cable-through hole is the circular cone shape through hole of lower thick upper thin；The upper surface of wiring sealing gasket is formed with multiple notch toroidal cavity upward, and each toroidal cavity surrounds the aperture, upper end of each cable-through hole respectively.The rosette that the present invention provides, can prevent the fine granularity object in connection box for motor from entering motor cavity.
Description
Technical field
The present invention relates to technology, particularly relate to the technology of a kind of permanent protective property connection box for motor.
Background technology
Connection box for motor is typically provided with wiring sealing gasket with the joint portion of motor case, and the effect of wiring sealing gasket is to increase
Add the sealing of connection box for motor and motor case joint portion, to prevent the objects such as steam outside motor case, dust from entering
Motor cavity；And can prevent the fine granularity object in connection box for motor from entering motor cavity.Wiring sealing gasket offers
Some cable-through holes, penetrate connection box for motor for the cable within motor case, but the cable-through hole on existing wiring sealing gasket
Being columned through hole, after cable passes cable-through hole, can leave gap between cable and cable-through hole hole wall, this gives motor wiring
Fine granularity object in box enters motor cavity and provides route of entry, thus has influence on the integral protection performance of motor.
Summary of the invention
For defect present in above-mentioned prior art, the technical problem to be solved is to provide one and can prevent
Fine granularity object in connection box for motor enters motor cavity, it is thus possible to improve the permanent protective property electricity of motor integral protection performance
Machine rosette.
In order to solve above-mentioned technical problem, a kind of permanent protective property connection box for motor provided by the present invention, including box body, institute
The lower end stating box body offers cable entries, and the wiring being provided with the cable entries covering box body bottom on box body seals
Pad；It is characterized in that: be formed with multiple downwardly projecting projection on described wiring sealing gasket, each projection offers one
The cable-through hole of up/down perforation, described cable-through hole is the circular cone shape through hole of lower thick upper thin；The upper surface of wiring sealing gasket is formed
Multiple notches toroidal cavity upward, and each toroidal cavity surrounds the aperture, upper end of each cable-through hole respectively.
The permanent protective property connection box for motor that the present invention provides, is designed to circular cone shape by the cable-through hole on wiring sealing gasket,
The cable-through hole of this circular cone shape coordinates the toroidal cavity of wiring sealing gasket upper surface, can well wrap through line
Cable, and also will not increase threading difficulty, can prevent the fine granularity object in connection box for motor from entering motor cavity, it is thus possible to
Improve motor integral protection performance.

Fig. 2 is the top view of the wiring sealing gasket in the permanent protective property connection box for motor of the embodiment of the present invention；
After Fig. 3 is the line A-A cutting along Fig. 2 of the wiring sealing gasket in the permanent protective property connection box for motor of the embodiment of the present invention
Cross section view.
Detailed description of the invention
Illustrate embodiments of the invention are described in further detail below in conjunction with accompanying drawing, but the present embodiment is not used to limit
The present invention processed, the analog structure of every employing present invention and similar change thereof, protection scope of the present invention, the present invention all should be listed in
In pause mark all represent the relation of sum.
As shown in Figure 1-Figure 3, a kind of permanent protective property connection box for motor that the embodiment of the present invention is provided, including box body 1, institute
The lower end stating box body 1 offers cable entries, and the wiring being provided with the cable entries covering box body bottom on box body 1 is close
Packing 2；It is characterized in that: be formed with multiple downwardly projecting projection 22 on described wiring sealing gasket 2, each projection 22 is opened
Being provided with the cable-through hole 21 of a up/down perforation, described cable-through hole 21 is the circular cone shape through hole of lower thick upper thin；Wiring sealing gasket 2
Upper surface is formed with multiple notch toroidal cavity 23 upward, and each toroidal cavity 23 surrounds each cable-through hole 21 respectively
Aperture, upper end.
In the embodiment of the present invention, wiring sealing gasket 2 designs each projection 22, the degree of depth of cable-through hole can be increased, and
Design toroidal cavity 23 at wiring sealing gasket 2 upper surface, the dilatancy in aperture, cable-through hole upper end can be increased, in order to cable
Pass；The aperture, lower end (big mouth) of cable-through hole should be more than the external diameter of cable, and the aperture, upper end (osculum) of cable-through hole should be smaller
External diameter in cable so that after cable passes cable-through hole, the upper end of cable-through hole and cable interference fit so that the upper end of cable-through hole
Cable can be wrapped.
