Abstract
The utility model relates to a junction box for a synchronous motor. The junction box comprises a box body and a box cover. The front side of the box body is opening, and the box cover is installed at the front side of the box body. The installation plate is provided with a stepped threaded hole, and the rear side surface of the installation plate is provided with an arc-shaped groove surface. A side part of the box body is provided with a heat dissipation plate, and an inner side of the heat dissipation plate is provided with a plurality of V-shaped grooves. Correspondingly, an outer side of the heat dissipation plate is provided with a plurality of trapezoid grooves. The left end of the box cover is hinged to the left side part of the box body. Correspondingly, the interior of the right side part of the box body is provided with a limiting block. The right end of the box cover blocks the outer side of the limiting block. The front end of the right side part of the box body is provided with a fixing screw, and the head part of the fixing screw partly blocks the outer side of the right end of the box cover. Through the arrangement of the arc-shaped groove, the junction box is in favor of directly installing the box body at the exterior of a motor base. The junction box is in favor of the heat dissipation of a wire in the box body and the heat dissipation of an electrical element through the arrangement of the heat dissipation plate with the V-shaped grooves and the grooves, thereby prolonging the service life.
Description
Technical field
The utility model relates to technical field of motors, relates in particular to a kind of for the terminal box on synchronous machine.
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.Yet, existing connection box for motor can not meet the outside that box body is directly installed on electric machine stand, this brings great inconvenience to installation personnel, the connection box for motor heat abstractor radiating effect also having is not obvious, in the life-span that is unfavorable for extending the interior electric wire of box body and electric component, can not meet real Production requirement.
Utility model content
Goal of the invention of the present utility model is in order to overcome the deficiencies in the prior art, provides a kind of for synchronous machine, simple installation, good heat dissipation, the terminal box of long service life.
In order to realize foregoing invention object, the utility model is to be achieved through the following technical solutions:
For the terminal box on synchronous machine, comprise box body and lid, described box body front openings, lid is arranged on box body front side, and the rear side of described box body is provided with mounting panel, and described mounting panel is provided with ladder screwed hole, and mounting panel trailing flank is arc groove face; Box body sidepiece is provided with heating panel, and described heating panel inner side is provided with a plurality of V-shaped grooves, and corresponding heating panel outside is provided with a plurality of trapezoidal grooves; The left end of described lid is hinged on the left side of box body, in corresponding box portion right sidepiece, guide vane end stop is installed, and lid right-hand member gear is in guide vane end stop outside; Described box portion right sidepiece front end is equipped with hold-down screw, and the local gear of head of hold-down screw is in lid right-hand member outside.
As preferably, in the middle part of described lid, be consolidated with observation window, the right-hand member of lid is also consolidated with handle.
As preferably, the lower end of described box body is provided with two wiring inlets.
As preferably, described ladder screwed hole has two at least, and is symmetrically distributed in mounting panel both sides.
During on-the-spot use, operating personnel connect the utility model on electric machine stand by box body by ladder screwed hole, simple installation.
Compared with prior art, the beneficial effects of the utility model are: the utility model contributes to box body to be directly installed on by arc groove face is set the outside of electric machine stand, by being provided with the heating panel of V-shaped groove and trapezoidal groove, contribute to the heat radiation of box body internal wire and electric component, the useful life of extending wire and electric component.
Accompanying drawing explanation
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
