Abstract
The utility model relates to a grounding terminal board for a vehicle, which employs a centralized grounding terminal board structure, wherein the grounding terminal board is a special grounding terminal, the grounding wires of the special devices on the vehicle are together connected with the grounding terminal board, and the grounding terminal board is integrally grounded together with the vehicle body, thereby effectively reducing the welding workload for mounting a grounding block on the vehicle, being convenient in construction, troubleshooting, mounting and dismounting, and simultaneously and correspondingly reducing the manufacture cost of the vehicle. The grounding terminal board for a vehicle comprises a grounding terminal mounted on a guide rail, the grounding wires of the devices on the vehicle are connected with the grounding terminal, and the rear portion of the guide rail is mounted and fixed in a slot.
Description
Technical field
The utility model relates to a kind of terminal board that the railway vehicle device earth connection is installed concentratedly that is used for, and belongs to mechanical manufacturing field.
Background technology
Based on the lifting and the improvement of taking environment of travel speed, on such as rail vehicles such as domestic motor train unit train, subway and urban light rails, used a large amount of mobile units, formed comparatively complicated electric control system.
Be to improve equipment uses on the car stability and fail safe, need the earth connection of electric equipment is connected down to car, be about to earth connection respectively through bogie, wheel to downward connection to carry out ground connection processing.
Usually be required to be equipment configuration ground connection piece on the existing car, earth connection connects the ground connection piece in advance, and the ground connection piece connects down to car again.Because equipment is more on the car, this type of ground connection piece just need be provided with a plurality of dispersedly, has not only increased the workload of car body welding ground connection piece.And ground connection handles and to disperse, to be unfavorable for improving on-the-spot installation, debugging and overhaul efficiency, also is difficult to search in time the fault point.
In view of this special present patent application that proposes.
The utility model content
The described vehicle grounding terminal block of the utility model, it is special-purpose grounding terminals that its purpose of design is to address the above problem and adopt centralized grounding terminal block structure, grounding terminal block; The earth connection concentrated area of particular device is connected in grounding terminal block on the car, and grounding terminal block is whole again with car body ground connection, thereby reduces the welding job amount that ground connection piece on the car is installed effectively; Convenient construction; Maintenance, dismounting correspondingly reduces the vehicle manufacturing cost simultaneously.
Another purpose of design is, takes the processing of centralized ground connection, can improve the earth connection efficiency of construction, and the operating efficiency of later stage debugging, maintenance is higher, also can find out the fault point in time.
For realizing above-mentioned purpose of design, said vehicle grounding terminal block mainly includes:
Be installed on the earth terminal on the guide rail, the earth connection of vehicle arrangement is connected in earth terminal, and the rear portion of guide rail is mounted on wire casing.
Like above-mentioned basic scheme characteristic; Earth terminal can be fixed in wire casing easily through guide rail; Earth terminal carries out ground connection processing to following connection of car uniformly; Thereby earth terminal equipment on car provides a centralized grounding terminals, and the earth connection of equipment all can be directly connected in earth terminal on most of cars, and need not to consider to carry out the problem that ground connection is handled again.
For improving the earth terminal mounting stability, the improvement project that can take is that the claw of guide rail is plugged in the draw-in groove at earth terminal rear portion.Be that earth terminal adopts the buckle connected mode, installation and removal are changed all comparatively simple.
The earth connection that earth terminal connected has the plurality of specifications size, is 4mm like sectional area
2, 10mm
2, 16mm
2Deng, can the plurality of specifications and the terminal of profile be integrated into one to this and sentence the convenience that raising ground connection is connected, the extremal subset that promptly described earth terminal has different cables cross section specification is formed in the monolithic construction on the same guide rail.
As above content, advantage and beneficial effect that the utility model vehicle grounding terminal block has are:
1, can carry out the processing of centralized ground ground connection as required onboard, the position of special-purpose grounding terminals can be chosen wantonly, helps the installation that is provided with of car inner part.
2, take the earth connection concentrated area to be connected in grounding terminal block, can reduce the quantity and the workload of ground connection piece effectively.
3, can improve the efficient of earth connection construction, debugging and maintenance, find out the fault point in time.
Description of drawings
The following accompanying drawing of existing combination is done explanation further to the utility model.
Fig. 1 is the structural representation of said grounding terminal block;
Fig. 2 is the vertical profile sectional view of Fig. 1;
As depicted in figs. 1 and 2, guide rail 1, earth terminal 2, earth connection 3, wire casing 4, claw 5, draw-in groove 6.
Embodiment
The rear portion of guide rail 1 is mounted on wire casing 4, and the earth connection 3 of vehicle arrangement is connected in earth terminal 2.
The claw 5 of guide rail 1 is plugged in the draw-in groove 6 at earth terminal 2 rear portions, to install and fix earth terminal 2.
Earth terminal 2 has cable cross section 4mm
2, 10mm
2, 16mm
2The terminal of three kinds of specifications, these terminals all are integrated into monolithic construction, and earth terminal 2 integrally is installed on the same guide rail 1.
Claims (3)
1. vehicle grounding terminal block, it is characterized in that: comprise the earth terminal (2) that is installed on the guide rail (1), the earth connection of vehicle arrangement (3) is connected in earth terminal (2);
