Description

The motor terminal box

Technical field

The utility model relates to a kind of terminal box, relate in particular to a kind of motor terminal box, it has a middle ring that is installed on the terminal box base, and described middle ring can be adjusted the relative position of outlet screw and base by a pipe joint, thereby changes the outlet direction of motor easily; Ring can be installed a rectifier simultaneously easily in described.

Background technology

Motor is widely used in all industries, is the source of power.In the design of general motor, the electric terminal of outside connection can be set in the shell body appropriate location, these terminals can be taken in protection with box body, and this box body is commonly referred to as terminal box.The motor terminal box of prior art comprises the end box that can be installed on motor body shown in No. 347166,513009, TaiWan, China patent announcement, and the loam cake that combines with this end box, each other with the assembling that mutually combines of the mode of screw or buckle.In use, electric terminal is to be provided with or to be installed in the end box usually, and the appropriate location of end box is established a wire hole again, so that external distribution is inserted and be connected in this electric terminal.Above-mentioned this motor terminal box, the following problem of normal generation in practical operation:

One, the installation site of motor is often because of the restriction of environment space, and can't outwards connect distribution by its default wire hole very smoothly.The method of improving also can be dismantled end box adjusting its wire hole direction except that the crooked distribution of trying one's best, but because end box is defined with respect to the installation site of motor, becomes down or a left side becomes the reverse adjustment on the right side so only can do.

Two, when the outlet direction adjustment of carrying out as above, must dismantle loam cake and end box, just end box can be turned to, to adjust its outlet direction; And after adjusting must according to the dismounting mode with screw one by one screw lock, with loam cake and the combination of end box so expend time in especially so that end box is installed on motor.

Three, the end box of prior art is an integral type, so carry out in the space that distribution is only limited in this end box, when running into complicated or bulky distribution, must change big box body but box Cheng Na space, the end is often not enough; But the setting of the installation site of box on motor, the aforesaid end, this box body is changed may not be feasible.

Four, the outer pipe joint with the arrangement distribution that is connected of the end box wire hole of prior art after the one male end is passed wire hole, with nut and external thread spiro fastening, and is fixed in this pipe joint on the end box; But so design when protruding distribution, must make up through screw dismounting repeatedly equally, and screw is very easily lost in this process.

Five, the rectifier fixed base plate of prior art need extend the waterproof film that a thin slice enters the terminal box bottom surface, so will make the face of waterproof film press unequal and cause leaking, and then reduce classification of waterproof, even can cause whole motor short circuit and burn.And this fixed form must will just can re-assembly rectifier and terminal box after the whole terminal box dismounting.

The utility model content

For solving many shortcomings of above motor terminal box, so the utility model provides another kind of motor terminal box, it has one can be installed on the base of motor body, and the loam cake that combines with described base, and the seat board upper surface of wherein said base forms the wedge wall with a height; One has the middle ring of height anchor ring, can be nested with the wedge wall periphery at above-mentioned base, and at least one outlet screw is set on the anchor ring; At least one pipe joint in being screwed into the external screw thread of one end in the outlet screw of ring, and is replaced the wedge wall outer surface of base with the male end face, thereby middle ring is combined with base.

The motor terminal box of said structure of the present utility model is compared with existing motor terminal box, has following advantage at least, thereby can solve the shortcoming corresponding with it:

(1) middle ring of the present utility model can place the appropriate location along the wedge wall outer race of base, and finds out best outlet direction.Therefore, can solve existing motor terminal box wire hole and limit, and can't outwards connect the problem of distribution smoothly because of environment space.

(2) the utility model only need be transferred loose pipe joint, can pass through to adjust the outlet screw of described middle ring and the relative position of base, and the outlet direction of easy change motor.Therefore, can solve existing motor terminal box box at the bottom of the removal repeatedly, just can carry out the problem that outlet direction is adjusted.

(3) ring can be according to the demand in distribution space in of the present utility model, thus easily from the described base removal enlarge its distribution space.Therefore, the problem of the distribution insufficient space that box produced at the bottom of the integral type of not existing motor terminal box.

(4) pipe joint of the present utility model is that direct spiral shell is in the outlet screw of middle ring, so when carrying out outlet direction adjustment or protruding distribution, all only need the removal that screws togather of this pipe joint of control to get final product, do not have the problem of the nut repeated disassembled and assembled of terminal box now, so can reduce the possibility that part is lost yet.

(5) ring does not set out the installed surface that can be provided as a rectifier on arbitrary anchor ring of line screw in of the present utility model, and its mounting means can not destroy this anchor ring, promptly do not influence the classification of waterproof of terminal box, the stator that can solve existing rectifier extends into that terminal box causes leaks and the shortcoming of motor short circuit.
