Abstract
The invention discloses a wire-outlet box for a motor. The wire-outlet box comprises a box seat and a box cover, wherein the box seat and the box cover are both made of metal sheet; two flangings turned outwards, namely a first flanging and a second flanging, are formed in the opening of the jointing surface of the box seat; one end of the first flanging is connected with the jointing surface; the second flanging is connected with the other end of the first flanging and is parallel with the jointing surface; and another flanging is formed at the periphery of the box cover. The wire-outlet box provided by the invention can prevent water current ejected in multiple directions, so as to be good at both waterproofing and dustproofing. The wire-outlet box can eliminate the impact that is imposed by the performance of a sealing washer on the waterproof performance of the wire-outlet box, while guaranteeing the waterproof performance of the wire-outlet box for the motor in multiple directions.
Description
Technical field
The present invention relates to the outlet box of motor appurtenances technical field, especially motor.
Background technology
The motor outlet box is a kind of motor auxiliary device that is connected on the motor housing, is mainly used in the high-tension cable that connects direct drive motors work, thereby requires to have higher waterproof and dustproof performance.Because in some scenarios, motor needs reverse even stands upside down and install, thereby requires outlet box on a plurality of directions, to guarantee favorable waterproof property.Present outlet box installs washer sealing additional at the joint of cassette holder and lid usually; But such outlet box sealing property depends on the performance of seal washer fully; In case packing ring is because high temperature or cold and heat succeed each other and wear out; Water resistance will reduce greatly, even can not waterproof, and the safe operation of motor has been caused threat.
Summary of the invention
The applicant is to the existing insecure problem of motor outlet box composition surface water resistance; Study improvement; Another kind of motor outlet box is provided, eliminates of the influence of the performance of seal washer, guarantee the water resistance of motor outlet box on a plurality of directions simultaneously the outlet box water resistance.
Technical scheme of the present invention is following.
A kind of motor outlet box comprises the cassette holder and the lid of sheet metal structural, and the opening part on the composition surface of said cassette holder has the flange that twice are turned up, and is respectively first flange and second flange, and an end of first flange is connected with said composition surface; Second flange connects with the other end of first flange and is parallel with said composition surface; The periphery of said lid has flange.
Its further technical scheme is:
Have screwed hole on second flange, correspondence offers through hole on the lid; Through the bolt in the said through hole lid is screwed onto on the cassette holder;
The outer rim of the flange on the said lid is alignd with the outer wall of cassette holder.
Beneficial effect of the present invention is following.
The present invention does not need packing ring can play good waterproof and dustproof effect, has eliminated the influence of seal washer performance to the outlet box sealing property; The present invention can also stop the current of penetrating from a plurality of directions; Have favorable waterproof property: the current that are mapped on the lid can flow down from the flange of lid, get into from the side in the groove that the current in flange and the gap between the cassette holder of lid can surround through composition surface and twice flange to flow out.
Description of drawings
Fig. 1 is that master of the present invention looks cutaway view.
Fig. 2 is the partial enlarged drawing at A place among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present invention is described.
As shown in Figure 2, the present invention includes the cassette holder 1 and lid 4 of sheet metal structural, the opening part on the composition surface 2 of cassette holder 1 has the flange that twice are turned up continuously, is followed successively by first flange 3 and second flange, 6, the second flange 6 are parallel with composition surface 2; The periphery of 4 lids has right angle flange 7, and the outer rim of flange 7 is alignd with the outer wall of cassette holder 1.Have screwed hole on second flange 6, correspondence offers through hole on the lid 4; Cassette holder 1 is fastening through the bolt 5 in the said through hole with lid 4.
Gap between the edge of flange 7 and the composition surface 2 should be at 2 ~ 5mm, and this gap is not a fit clearance, and is not high to the morpheme error requirements, thereby also can reduce production cost of the present invention.
As shown in Figure 1, during use, inside of the present invention also need connect insulator 13 on inwall, and an end of insulator 13 is equipped with lead row 12, in order to winding displacement be connected the outlet cable; In one side of cassette holder 1 gland head 11 is installed, is used for the feed cable that box is outer and introduces outlet box, use favorable waterproof property; Elastic tape cable joint-box 10 is installed in the downside of cassette holder 1, is used for outlet box is introduced in the wiring of motor, certain water resistance is arranged; The downside of cassette holder 1 also is connected with studs 9, and double-screw bolt 9 one ends are connected on the motor housing, and the other end is fastened on the cassette holder 1 through nut 8.
Electric component in the outlet box belongs to prior art, not in claim scope of the present invention; It is a kind of in numerous types of attachment that lid described in the present embodiment is connected with the bolt of cassette holder, is characterized in simple in structure, easy accessibility; Can certainly be other type of attachment, like spring leaf connection, the connection of snap ring buckle etc.
More than describing is to explanation of the present invention, is not limitation of the present invention, and institute of the present invention restricted portion is referring to claim.Under the situation of basic structure of the present invention, the present invention can do any type of modification.
