Abstract
The utility model discloses a simple grounding screw which comprises a screw bolt and a compressing nut. The screw bolt passes through a power board. An in-vehicle grounding soldering flake and an outer-vehicle grounding soldering flake are respectively sleeved on the screw bolt. The in-vehicle grounding soldering flake is fixedly connected with the inside of the power board through a fastener. The outer-vehicle grounding soldering flake is fixedly connected with the outside of the power board through the compressing nut. The screw bolt is a double-end stud which is provided with a flange at the middle part and is provided with screws at both ends. The compressing nut is a wing nut. The simple grounding screw has the following advantages: simple structure, convenient operation and use. At the outside of the vehicle, the screw bolt is fixedly connected with the power board through the flange at the middle part. The connection is reliable and the cost is saved. The wing nut is adopted so that the soldering flake of the outer-vehicle grounding wire can be detached without a specialized tool. The operation efficiency is increased. Silver is coated on the surface of each component. Not only is cost saved for protecting each component from corrosion, but also the conductivity of the grounding wire is improved.
Description
Technical field
The utility model relates to the earthing screw that uses on a kind of vehicle wall box, especially a kind ofly conducts electricity very well, earthing screw easy to use, belongs to vehicle electric accessory technical field.
Background technique
In order to prevent the damage that gets shocked of equipment and circuit, the normal operation of support equipment, the shell of some electrical equipments has grounding requirement usually, for example on the wall box panel of vehicle earthing screw is housed.Existing earthing screw adopts zinc-plating material to make mostly, and electric conductivity and antiseptic property are relatively poor, and the ground connection effect of vehicle is had certain influence, in addition, the weld tabs of the external ground wire of car adopts common hexagon nut to compress, and special tools such as needs use spanner carry out dismounting, operate very inconvenient.
The model utility content
The purpose of this utility model provides a kind of simple in structure, conduction and antiseptic property simple and easy earthing screw good, easy and simple to handle.
The utility model is achieved by the following technical programs:
A kind of simple and easy earthing screw, comprise screw rod, gland nut, described screw rod passes power panel, ground connection weld tabs, car external ground weld tabs are set on the described screw rod in the car, the ground connection weld tabs is fixedlyed connected with the power panel inboard by fastening piece in the car, car external ground weld tabs is fixedlyed connected by described gland nut and the power panel outside, and described screw rod is provided with the stud that flange, two ends are provided with screw thread for the centre, and described gland nut is a wing nut.
The purpose of this utility model can also further realize by following technical measures.
Aforesaid simple and easy earthing screw, the surface of wherein said screw rod, gland nut, fastening piece is all silver-plated.
The utility model is simple in structure, and is easy for operation.In the car outside, screw rod is fixedlyed connected with power panel by spacer flanger, can reduce the quantity of pad, connects reliably, saves cost; After adopting wing nut, need not to use the special tool weld tabs of the external ground wire of dismounting vehicle easily, improved working efficiency; Each component surface is all carried out silver-plated processing, and is not perishable, both saved cost, improved the electric conductivity of ground wire again.
Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiments only provide as an example with reference to accompanying drawing.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model screw rod.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1 and Figure 2, the utility model comprises screw rod 1, gland nut 2, and screw rod 1 is shaped on the stud that flange 11, two ends are shaped on screw thread 12 for middle, and the both sides of flange 11 are provided with tool withdrawal groove 13, and gland nut 2 adopts wing nuts; Screw rod 1 passes the mounting hole on the power panel 3, screw rod 1 both sides are set with ground connection weld tabs 4, car external ground weld tabs 5 in the car, ground connection weld tabs 4 is fixedlyed connected with the inboard of power panel 3 by hexagon nut 6, plain washer 7, elastic washer 8 in the car, the spacer flanger 11 of screw rod 1 is positioned at outside the power panel 3 simultaneously, by gland nut 2 car external ground weld tabs 5 is pressed against spacer flanger 11 outsides, because gland nut 2 is a wing nut, need not to use special tool dismounting vehicle external ground weld tabs 5 easily.The surface of screw rod 1, gland nut 2, hexagon nut 6, plain washer 7, elastic washer 8 is all silver-plated, not only saves cost, improves the antiseptic property of each member simultaneously, has prolonged working life, has also improved the electric conductivity of ground wire.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
Claims (2)
1. simple and easy earthing screw, comprise screw rod, gland nut, described screw rod passes power panel, ground connection weld tabs, car external ground weld tabs are set on the described screw rod in the car, it is characterized in that: the ground connection weld tabs is fixedlyed connected with the power panel inboard by fastening piece in the described car, and car external ground weld tabs is fixedlyed connected with the power panel outside by described gland nut; Described screw rod is provided with the stud that flange, two ends are provided with screw thread for middle, and described gland nut is a wing nut.
