Abstract
The invention discloses a waterproof junction box which comprises a junction box base and asymmetrical flange sides; one end of the junction box is set as an inner cavity with a bottom; the asymmetrical flange sides are arranged on the outer ring of an opening for assembling a wiring terminal, and are provided with through holes. The scheme that the junction box base is integrated with a junction box cover is adopted to eliminate a butting surface between the junction box cover and the junction box base, thereby absolutely solving the sealing problem and prolonging the service life of the motor.
Description
Technical field: the present invention relates to a kind of waterproof junction box.Be applicable to the use of connection box for motor under the high humidity environment.
Background technology: the maximum relative humidity of the surrounding air that threephase asynchronous is suitable for is no more than 95% (temperature is 25 ℃), after motor makes moist, can reduce the insulation degree, causes insulation breakdown; The ring motor is burnt in heating easily.Motor makes moist generally and to infilter from the composition surface of composition surface, connector cover and the junction box seat of gap, junction box seat and support between end cap and support joint, end cap and the rotating shaft.The waterproof problem on the composition surface of gap, junction box seat and support between end cap and support joint, end cap and the rotating shaft can solve through fluid sealant and outside framework oil seal; And the never good solution of the composition surface waterproof problem of connector cover and junction box seat reduces motor useful life.
Summary of the invention: the object of the invention will provide a kind of waterproof junction box exactly, and it can solve the composition surface of present connector cover and junction box seat can not waterproof problem.The objective of the invention is to realize like this; A kind of waterproof junction box comprises that junction box seat, asymmetric flange form, and it is characterized in that: an end is arranged to the inner chamber at the end; The outer ring that is used to assemble the opening part of binding post is provided with asymmetric flange, and is provided with through hole above that.
The scheme that the present invention has adopted junction box seat and connector cover to be integrated, the composition surface of having eliminated connector cover and junction box seat, thus thoroughly solved sealing problem, prolonged the useful life of motor.
Description of drawings:
Fig. 1 uses terminal box for the motor general environment;
Fig. 2 is a structural representation of the present invention;
1, junction box seat, 2, binding post, 3, connector cover, 4, asymmetric flange, 5. through hole.
Embodiment: the present invention is described further below in conjunction with accompanying drawing;
A kind of waterproof junction box comprises junction box seat 1,4 compositions of asymmetric flange, and it is characterized in that: an end is arranged to the inner chamber at the end, and the opening part outer ring that is used to assemble binding post is provided with asymmetric flange 4, and is provided with through hole 5 above that.During practical implementation,,, junction box seat and connector cover are fused into one, thoroughly solved sealing problem with the insulating material cast according to the drawing designing mould.
