Description
Technical field
The utility model is related to connection box for motor under connection box for motor technical field more particularly to a kind of wet environment to seal
Device.
Background technology
Blower motor in Central air-conditioning unit is chronically at the working environment of high humility, therefore it is required that motor is integrally close
Envelope is good, to ensure electrical insulation properties qualification.However, motor will open connector cover when doing regular servicing every year, weight
It will cause the original sealing rubber ring of terminal box that different degrees of damage occurs after answering repeatedly, lose sealing function, moisture and dust are such as
Into inside motor, the bad, decreasing insulating of coil heat dissipation can be made, burn-down of electrical machinery may be led to for a long time by going down.It is close to meet
Envelope requires, open every time connector cover again closing lid when be required for breaking fluid sealant, but influenced by machining accuracy, connection box for motor body
It is not complete plane with box cover contact surface, though there are a large amount of colloids when gluing, will appear after the extruding of box cover screw and beat
Glue surface colloid non-uniform phenomenon, influences sealing effect；In addition, because colloid action needs just pry open by tool when uncapping again
Connector cover, it is not only dangerous but also working efficiency can be influenced, and open need to scrape in old glue after lid it is totally again close to break virgin rubber
Envelope.
Utility model content
The purpose of this utility model is to provide connection box for motor sealing device under a kind of wet environment, can avoid every time
Gluing seals again after opening terminal box, while fully meeting the seal request of connection box for motor, improves maintenance of motor efficiency.
To achieve the above object, the technical solution adopted in the utility model is；
Connection box for motor sealing device under a kind of wet environment, including gasket and seal convexity, the gasket be
The framework of rectangular box structure, gasket and connection box for motor matches, and multiple screw positioning are circumferentially offered on gasket
Hole, the seal convexity are circumferentially disposed at the bottom of gasket, and the seal groove of seal convexity and connection box for motor matches.
The gasket and seal convexity is structure as a whole, and gasket and seal convexity are all made of silicon rubber and are made.
The section of the seal convexity is trapezoidal or semicircle.
The frame width of the gasket is bigger 2mm than the frame width of connection box for motor.
The utility model is padded according to the physical form and external structure of connection box for motor using the sealing of rectangular box shape
It is now fully bonded with box body and two mounting planes of box cover, using the seal convexity of gasket bottom is embedded in connection box for motor
Seal groove can increase fiting effect and because gap caused by gasket wrinkle.The sealing device of the utility model
The sealing problem for solving connection box for motor under wet environment, realizes ideal sealing effect, is effectively improved motor inner loop
Border prevents motor premature aging.

Fig. 3 is the sectional view of the seal convexity of trapezoid cross section；
Fig. 4 is the sectional view of the seal convexity of semi-circular cross-section.
Specific implementation mode
To make the technological means, creation characteristic, reached purpose and advantageous effect of the utility model be easy to understand, under
Face combines specific implementation mode, and the utility model is expanded on further.
As depicted in figs. 1 and 2, connection box for motor sealing device under a kind of wet environment described in the utility model, including
Gasket 1 and seal convexity 2, gasket 1 and seal convexity 2 are structure as a whole, using not only high temperature resistant but also cold-resistant, and also it is electrical
The silicon rubber of excellent insulating property is made.Gasket 1 is rectangular box structure, is matched with the framework shape of connection box for motor,
For the box body of sealed electric-motor terminal box and the faying face of box cover.In order to avoid poorly sealed, the frame width D ratios of gasket 1
The big 2mm of frame width of connection box for motor fully ensures that the faying face of connection box for motor is completely covered by gasket 1.Gasket 1
On circumferentially offer four screw location holes 3, using fastening screw gasket 1 can be fixed on connection box for motor box cover and
Between box body.Seal convexity 2 is circumferentially disposed at the bottom of gasket 1, the sealing groove shape of seal convexity 2 and connection box for motor
Match, by making seal convexity 2 be embedded in the seal groove of connection box for motor, sealing effect and sealing can be increased
It pads 1 wrinkle and generates gap.As shown in Figure 3 and Figure 4, the section of seal convexity 2 can be trapezoidal or semicircle.
When the utility model is used, first lying against gasket 1 on the box body of connection box for motor, make have seal convexity 2
One downwards, so that it is embedded in the seal groove of connection box for motor by pressing, the upper and lower surface of pad 1 to be sealed respectively with box body
After being fully bonded with two mounting planes of box cover, box cover is closed, the fastening screw for connecting box cover and box body passes through on gasket 1
Screw location hole 3 three is fixed.The utility model solves that connection box for motor gluing sealing effect under wet environment is poor, work
Make the big problem of difficulty, realize ideal sealing effect, is effectively improved motor internal environment, prevents motor premature aging, prolong
Long life.
The advantages of main feature, basic principle and the utility model of the utility model has been shown and described above.This
Field technology personnel it should be appreciated that the present utility model is not limited to the above embodiments, do not depart from the spirit of the present invention and
Under the premise of range, the utility model can also make various changes and modifications according to actual conditions, these changes and improvements are all fallen
Enter the requires of the utility model protection in the range of.
