Abstract
Provided is a positive pressure explosion-proof junction box structure, comprising a box. A surface of the box is a fitting surface with a motor. A lead hole is disposed on the fitting surface. Lead wires in the motor enter the box through the lead hole. The lead hole is disposed on the fitting surface of the junction box and the motor, so lead wires in the motor enter directly into the junction box through the lead hole, so not only tightness of the junction box is improved and space is saved, but also additional protection requirements on the lead wires are reduced. Two groups of wiring boards are arranged in a stair-step shaped at different heights, so not only space on a junction box length direction is saved, but also electric clearances and creep age distances of connecting terminals are increased. Four edges of an open end of the box have flanges, so not only rain permeation is effectively prevented and tightness of the box is improved, but also space on a junction box width direction is saved, thereby contributing to reducing the size of the box.
Description
Technical field
The utility model belongs to motor anti-explosion terminal box technical field, relates to a kind of positive-pressure explosion-proof junction box structure.
Background technology
Connection box for motor, the UNICOM that is mainly used to realize motor internal and external power source, and effective exchange of motor internal signal and external signal.
The connecting line of existing positive-pressure explosion-proof terminal box and motor adopts the mode of outside inlet wire, therefore, not only needs connecting line is taked effective protection measure, and requires incoming line that higher sealing is arranged, thereby cause complex structure, and difficulty of processing is big.Existing terminal box back panel wiring plate is in sustained height, and for guaranteeing effective electric clearance and creepage distance, terminal block takes up space bigger, thereby makes that whole terminal box box body is bigger; For preventing that rainwater from infiltrating from the lid seam crossing, existing terminal box adopts the frame mode that adds overhanging edge on the box body, has increased the bulk of terminal box Width; On the existing terminal box lid fixed handle is set, also can occupies certain space at the terminal box Width.
Summary of the invention
The purpose of this utility model provides a kind of positive-pressure explosion-proof junction box structure, solves existing positive-pressure explosion-proof junction box structure complicated problems.
The purpose of this utility model is achieved in that the positive-pressure explosion-proof junction box structure, comprises box body, and the one side of box body is and the mating surface of motor, and mating surface is provided with fairlead, and the lead wire in the motor enters in the box body by fairlead.
Characteristics of the present utility model also are:
Be provided with two groups of terminal blocks in the above-mentioned box body, two groups of terminal blocks are stepped arranges and connects by copper busbar, and one group of terminal block is connected with lead wire, and another is organized terminal block and is connected with external cable.
The openend of above-mentioned box body is flange, and openend is provided with lid.
Above-mentioned lid is provided with folding handles.
The utlity model has following beneficial effect:
1, the utility model arranges fairlead at the mating surface of terminal box and motor, make the lead wire in the motor directly enter in the terminal box by fairlead, not only improve the sealing of terminal box, saved working space, and reduced the requirement of shelter extra to lead wire.
2, two groups of terminal blocks of the utility model adopt stepped arranging, height is different, not only can save the dimensional space of terminal box length direction, and under the prerequisite that guarantees rational electric clearance and creepage distance, can make the space utilization of Width more abundant rationally.
3, the utility model box body four limit flange not only can effectively prevent the infiltration of rainwater, have improved the sealing of box body, and have saved the space of terminal box Width, help to reduce the box body volume.
4, the utility model lid adopts collapsible handle, usually can handle is folding, reduced taking up room.
Description of drawings
Fig. 1 is the terminal box cut-away drawing;
Fig. 2 is terminal box lid handle figure;
Among the figure, 1. lead wire, 2. terminal block I, 3. copper busbar, 4. terminal block II, 5. lid, 6. folding handles.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Referring to Fig. 1, the positive-pressure explosion-proof junction box structure comprises box body, and the one side of box body is and the mating surface of motor, and mating surface is provided with fairlead, and the lead wire 1 in the motor enters in the box body by fairlead; Be provided with terminal block I 2 and terminal block II 4 in the box body, terminal block I 2 and terminal block II 4 be stepped arranges and is connected by copper busbar 3, and terminal block I 2 is connected with lead wire 1, and terminal block II 4 is connected with external cable.Openend four limits of box body are flange, and openend is provided with lid 5.Referring to Fig. 2, lid 5 is provided with folding handles 6.
In the lead wire 1 direct thereto in the utility model motor, avoided increasing the outside it has been carried out necessary safeguard measure, reduced the perforate quantity of terminal box bottom, improved sealing; The utility model adopts stair-stepping two groups of terminal blocks, can satisfy electric mechanical performance requirement, has reduced the bulk of terminal box length direction again, more reasonable use the space; The terminal box box body adopts turnup structure, has not only reduced the size of box body thickness direction, equally also can realize the function of rainproof waterproof.The utility model adopts folding handles, has avoided making space layout more rationally compact to interference and the obstruction of staff and other article on every side.
