Abstract
The utility model relates to a junction box, in particular to a special-shaped junction box for a subway, which is used for branching wires under metro vehicles and comprises a box body, a wiring board, a wire inlet binding rod and a wire outlet binding rod. The box body is in an special-shaped structure, one end of the box body is a big open end, the other end of the box body is a small closed end with a protrusion, the wiring board with a terminal strip and the wire inlet binding rod are arranged at the bottom of the box body, the wire outlet binding rod is arranged at the bottom and the lateral wall of the box body, a wire inlet and a wire outlet are arranged on two side walls of the box body respectively. The junction box is simple and reasonable in structure, flange holes can be evenly stressed so as to reach water-proof grade, and the junction box is convenient in assembly and maintenance, and the like.
Description
Technical field
The utility model relates to a kind of junction box, a kind of specifically special-shaped junction box who is used for separated time use under the railcar car.
Background technology
At present, along with the progress and the expanding economy of society, all there has been subway in many cities of China, and subway comfortable, quick and convenient becomes the important vehicles of people's trip, and subway has become the important component part of many urban transportations.Along with the function of subway train is more and more, element in the car and equipment also increase thereupon, thereby some shortcoming and defect of interior element of existing car and equipment also embody thereupon.
Past vehicle junction box generally all makes square for easy to process, but difficulty relatively when the square junction box installs flexible pipe under car, and can cause place, box flange hole because of distortion appears in discontinuity, finally cause casing can not reach classification of waterproof.Therefore the actual requirement for the junction box needs casing is carried out certain improvement.
Summary of the invention
The purpose of this utility model is to provide a kind of simple and reasonable, thereby can make the stressed junction box of being convenient to installation and maintenance who evenly reaches classification of waterproof of flange hole according to vehicle physical cabling situation is improved.
The purpose of this utility model is to realize like this, this junction box comprises casing, terminal block, inlet wire tie pole, outlet tie pole, described casing adopts abnormally-structured, one end of casing is that big opening end, the other end is the little blind end that has projection, have the terminal block of terminal board and the bottom that the inlet wire tie pole is arranged on casing, the outlet tie pole is arranged on the bottom and sidewall of casing, has entrance hole and wire hole respectively in the two side of casing.
The utlity model has following advantage:
1, the utility model has improved the maintainability and the operability of product, has improved whole reliability.
2, the utility model is arranged on the position of entrance hole tiltedly on the lower side, is because the position that the flexible pipe of general vehicle end of incoming cables is fixed is on the low side, so just can make the installation of flexible pipe more convenient, and casing is stressed more even.
3, the utility model is used for the fixing inlet wire tie pole of casing wiring and the outlet tie pole is set to short tie pole, can accomplish that wire harness is clearly demarcated, examination and maintenance are more convenient, in addition because the intensity of short tie pole is better than the intensity of long tie pole, concussion in the vehicle operating process just can not cause harmful effect to wire harness, has guaranteed the reliability of wiring on the terminal board.
Description of drawings
Fig. 1 is the overall structure schematic diagram of subway with special-shaped junction box.
Fig. 2 is that the A of Fig. 1 is to the projection structure schematic diagram.
Fig. 3 is that the B of Fig. 2 is to the projection structure schematic diagram.
Embodiment
Have a rectangular recess 11 below described casing 1 corresponding opening end 5 one sides, blind end has a wedge angle groove 10 on the 6 one side sides.
Described entrance hole 8 is arranged on the sloped sidewall of casing 1 one side wedge angle grooves 10, and wire hole 9 is arranged on the vertical sidewall of a corresponding side.
Described at least one outlet tie pole 4 is arranged in the rectangular recess 11 and on the sidewall of wire hole 9 one ends, at least one inlet wire tie pole 3 is arranged on casing 1 bottom near entrance hole 8 one sides.
During use line is penetrated from entrance hole 8, make it fixing, line is received on the separated time terminal board 7 again with casing 1 with inlet wire tie pole 3; Line is penetrated from wire hole 9, make it fixing with casing 1 with outlet tie pole 4, line is received on the separated time terminal board 7, the line that the line that enters from entrance hole 8 and wire hole 9 are entered is connected.Wherein terminal board 7, inlet wire tie pole 3 and quantity that tie pole 4 occurs can make this junction box have higher maintainability and operability according to the actual requirement setting of vehicle.
