Abstract
The utility model relates to a motor conjunction box, which includes a box body and connection terminals. An arc seat is arranged on the upper end of the box body. Threaded holes are arranged in two sides of the box body. A plurality of heat dissipation holes are arranged in the bottom of the box body. An observation window is arranged on the lower end of the box body. The arc seat is provided with lugs, and installation holes are arranged in the lugs. The connection terminals are installed in the threaded holes via threads. Each connection terminal is provided with a through hole, and a bell mouth is arranged in the right end of the connection terminal. The connection terminals with the bell mouths and the through holes facilitate connecting wires to electrical components or connectors inside the box body. With the bell mouths, externally connected wires can bend for certain angles, so that the wires can better adapt to arrangement of the internal electrical components. Arrangement of the plurality of heat dissipation holes facilitates heat dissipation of the wires and the electrical components inside the box body, so that the service lives of the wires and the electrical components are extended. Besides, the conjunction box is economic and practical with a simple structure and easy operation.
Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of connection box for motor.
Background technology
Under the coal mine that connection box for motor is mainly used in containing gas or coal dust explosion hazard, connection box for motor is the intrinsic safety termination under coal mine, and connection box for motor is used for intrinsic safety circuit two cores of mine supervision system and two wiring, the separated times that pass to four-way of quad.But, existing connection box for motor lacks external cord curve transition device, this can cause electric wire due to bending excessively, cause electric wire shell to break prematurely, but also can not make electric wire better adapt to the layout of box body electric elements inside, the connection box for motor heat abstractor radiating effect also having is not obvious, is unfavorable for extending the life-span of the interior electric wire of box body and electric component, can not meet real Production requirement.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, and a kind of connection box for motor is provided.
The utility model is to be achieved through the following technical solutions:
A kind of connection box for motor, comprise box body and junction block, the upper end of described box body is provided with arc-shaped seat, the both sides of described box body are provided with screwed hole, the bottom of box body is provided with some row's louvres, described junction block is arranged on screwed hole by screw thread, and junction block is provided with through hole, and the right-hand member of junction block is provided with horn mouth.
As optimal technical scheme of the present utility model, described junction block has two, and symmetry is arranged on screwed hole.
As optimal technical scheme of the present utility model, the lower end of described box body is also provided with observation window, and described arc-shaped seat is provided with lug, and described lug is provided with installing hole.
As optimal technical scheme of the present utility model, described louvre has four rows at least, and is evenly distributed on the bottom of box body.
When on-the-spot use, operating personnel are arranged on the utility model on electric machine stand by installing hole on lug, then electric wire is connected with electric component in box body by the through hole on junction block.
Compared with prior art, the beneficial effects of the utility model are: the utility model contributes to electric wire to be connected to electric component or the joint in box body by the junction block of horn mouth and through hole, horn mouth contributes to the external cord can bending certain angle, make electric wire better adapt to the layout of box body electric elements inside, by being set, some row's louvres contribute to the heat radiation of box body internal wire and electric component, the useful life of extending wire and electric component, and simple in structure, easy to operate, economical and practical.
