Abstract

The utility model discloses a motor outlet box which comprises a box base with a sheet metal structure and a box cover. The opening position of the bonding face of the box base is provided with two outward flanging edges which are respectively a first flanging edge and a second flanging edge, and one end of the first flanging edge is connected with the bonding face. The second flanging edge is connected with the other end of the first flanging edge and parallel to the bonding face. The periphery of the box cover is provided with a flanging edge. The motor outlet box can block water shot from multiple directions, has good waterproof performance, and can play good dustproof effect. The influence of the performance of a sealing washer on the waterproof performance of the motor outlet box can be eliminated, and waterproof performance of the motor outlet box in the multiple directions is guaranteed.

Description

A kind of motor wire outlet box

Technical field

The utility model relates to the outlet box of motor appurtenances technical field, especially motor.

Background technology

Motor wire outlet box is a kind of motor auxiliary device that is connected on the motor housing, is mainly used in connecting the high-tension cable of direct-driving motor work, thereby requires to have higher waterproof and dustproof performance.Because in some scenarios, motor needs oppositely even stands upside down and install, thereby requires outlet box to guarantee good water resistance in a plurality of directions.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, the safe operation of motor has been caused threat.

The utility model content

The applicant is for the insecure problem of existing motor wire outlet box composition surface water resistance, carry out Improvement, another kind of motor wire outlet box is provided, eliminates the performance of seal washer to the impact of outlet box water resistance, guarantee simultaneously the water resistance of motor wire outlet box on a plurality of directions.

The technical solution of the utility model is as follows.

A kind of motor wire outlet box comprises cassette holder and the lid of sheet metal structural, and the flange that the opening part on the composition surface of described cassette holder turns up with twice is respectively the first flange and the second flange, and an end of the first flange is connected with described composition surface; The second flange connects with the other end of the first flange and is parallel with described composition surface; The periphery of described lid is with flange.

Its further technical scheme is:

Have screwed hole on the second flange, correspondence offers through hole on the lid; By the bolt in the described through hole lid is screwed onto on the cassette holder;

The outer rim of the flange on the described lid is alignd with the outer wall of cassette holder.

The beneficial effects of the utility model are as follows.

The utility model does not need packing ring can play good waterproof and dustproof effect, has eliminated the impact of seal washer performance on the outlet box sealing property; The utility model can also stop from a plurality of directions penetrates next current, have good water resistance: the current that are mapped on the lid can flow down from the flange of lid, enter from the side in the groove that the current in the flange of lid and the gap between the cassette holder can surround by composition surface and twice flange to flow out.

Description of drawings

Fig. 1 is that master of the present utility model 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 utility model is described.

As shown in Figure 2, the utility model comprises the cassette holder 1 and lid 4 of sheet metal structural, and the flange that the opening part on the composition surface 2 of cassette holder 1 turns up continuously with twice is followed successively by the first flange 3 and the second flange 6, the second flange 6 are parallel with composition surface 2; The periphery of 4 lids is with 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 the second flange 6, correspondence offers through hole on the lid 4; Cassette holder 1 and lid 4 are fastening by the bolt 5 in the described through hole.

Gap between the edge of flange 7 and the composition surface 2 should be at 2 ~ 5mm, and this gap is not fit clearance, and is not high to the morpheme error requirements, thereby also can reduce production cost of the present utility model.

As shown in Figure 1, during use, the utility model inside also need to be on inwall connecting insulator 13, an end of insulator 13 is equipped with line conductor 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, with good water resistance; 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 by nut 8.

Electric component in the outlet box belongs to prior art, not in claim scope of the present utility model; 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, such as spring leaf connection, the connection of snap ring buckle etc.

More than describing is to explanation of the present utility model, is not to restriction of the present utility model, and the utility model limited range is referring to claim.In the situation of the utility model basic structure, the utility model can be done any type of modification.
