Description
Technical field
The utility model relates to a kind of electric machine structures, improve more specifically to a kind of junction box part of motor
Junction box structure of electrical machine.
Background technique
Motor refers to a kind of calutron that electric energy conversion or transmitting are realized according to the law of electromagnetic induction, its main function
It is to generate driving torque, as electrical appliance or the power source of various machinery.
In the structure of motor, terminal box and encoder are usually mounted on shell.There is multiple be used in terminal box
Connect the connector lug of high-voltage electricity (380V).There are two interfaces for encoder tool, and what two interfaces connected is low tension (7 volts).For
The electric current of both terminal box and encoder is avoided to interfere with each other, the two is separated by large distances: such as electric machine casing includes
Electric machine casing main body, drive end bearing bracket, rear end cap, terminal box are mounted on rear end cap, and encoder is then mounted on electric machine casing main body
On, and encoder is far from terminal box.
But this structure design, the volume of motor can be greatly increased, so that motor needs to occupy biggish space, greatly
The big cost for increasing the producer.Moreover, because terminal box is a component, it is installed on electric machine casing by connector, because
This its leakproofness is difficult to ensure, can generate adverse effect to motor performance.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of junction box structure of electrical machine, this connection box for motor knot
Structure can efficiently reduce the volume of motor.The technical solution adopted is as follows:
A kind of junction box structure of electrical machine, including electric machine casing main body, drive end bearing bracket, rear end cap, electric machine casing body front end tool
There is front opening, electric machine casing body rear has front end deutostoma, and drive end bearing bracket is mounted on the front opening of electric machine casing main body,
Rear end cap is mounted in the open rearward end of electric machine casing main body, it is characterised in that: the junction box structure of electrical machine further includes wiring
Box, encoder, the terminal box have multiple connector lugs for being used to connect high-voltage electricity, and terminal box is arranged on rear end cap, coding
There are two the interface of connection low tension, encoders to be mounted in terminal box for utensil, and straight line where each connector lug is parallel to each other, and respectively connects
Straight line where mouthful is parallel to each other, and straight line intersection where straight line where any connector lug and any interface, and any wiring
The angular range of straight line is 80-100 degree where straight line where head and any interface.In this way, when these connector lugs connect high-voltage electricity,
And when two interfaces connection low tension, interfered between each other by the high-voltage electricity of connector lug with the low tension for passing through interface it is smaller,
It will not influence the normal work of motor, therefore encoder, terminal box be combined into one to reach section space-efficient purpose, this knot
Structure, which improves, has practicability.
More optimal solution, the angular range of straight line is 85-95 degree where straight line where any connector lug and any interface.
Preferred scheme, line orthogonal where straight line where any connector lug and any interface.That is, any wiring
The angle of straight line is 90 degree where straight line where head and any interface.
Preferably scheme, the terminal box are made into integration with rear end cap.In this way, the leakproofness of terminal box is substantially improved,
Improve the performance of motor.
Preferably scheme, the terminal box top are equipped with opening, and the sealing cover unloaded can be opened by being equipped in opening.So just
In installation and maintenance.
Preferably scheme, the number of the connector lug are three.
Preferably scheme, the electric machine casing body top have at least one hanged hook.
Compared with the prior art, the utility model has the beneficial effect that due to being arranged encoder into terminal box, energy
Enough greatly reduce the volume of motor, and the angular range of straight line is 80-100 where straight line where any connector lug and any interface
Degree will not influence motor just so that interfering between each other by the high-voltage electricity of connector lug with the low tension for passing through interface smaller
Often work, so that encoder, terminal box, which are combined into one this structure and improve, has practicability and feasibility；The terminal box
It is made into integration with rear end cap, then substantially improves the leakproofness of terminal box, improve the performance of motor.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment 1；
Fig. 2 is the left view of embodiment illustrated in fig. 11；
Fig. 3 is that Fig. 2 removes the structural schematic diagram after sealing cover.
