Description

Circuit board and guide rail ammeter Technical Field The application relates to the technical field of electrical equipment, in particular to a circuit board and a guide rail ammeter. Background The guide rail ammeter is generally an electric energy metering device arranged on an electric guide rail and is mainly used in an industrial, commercial or residential power distribution system, and has the characteristics of convenience in installation and space saving. Rail meters are generally divided into two types of connections, direct and indirect. When the direct connection mode is selected, the guide rail ammeter is directly connected to the tested circuit. When the indirect connection mode is selected, the guide rail ammeter is connected into the tested circuit through a current transformer or a voltage transformer. In the prior art, when the guide rail ammeter adopts a direct connection mode, the problem that an internal circuit is damaged easily occurs, and thus the use reliability of the guide rail ammeter is lower. Disclosure of utility model The application provides a circuit board and an ammeter, which can improve the use reliability of a guide rail ammeter. In a first aspect, the present application provides a circuit board applied to a rail ammeter. The guideway ammeter comprises a base. The circuit board comprises a body and a wire arrangement structure. The body sets up in the base, and the body includes the relative first face of position and second face, and the diapire of base is dorsad to the first face, and the second face is equipped with welded structure on the first face towards the diapire of base. The reason line structure sets up on the body, and reason line structure locates the welding structure and is close to one side of body border, and reason line structure can communicate first face and second face, and reason line structure can provide the space of wearing for the voltage line for the one end of voltage line is connected to the base, and the other end is connected to welding structure. Through the scheme, the wire arrangement structure is arranged on the body, and the first surface and the second surface of the body can be communicated by using the wire arrangement structure, so that the second end of the voltage wire can penetrate through the body and be welded with the welding structure arranged on the first surface. Compared with the mode that the voltage line is connected with the second surface in the prior art, the voltage line penetrates through the body and is connected with the first surface, so that the voltage line can be straightened, and the probability of stacking problems between the second surface and the base caused by overlong voltage lines is reduced. After the voltage line is straightened, the possibility that the voltage line was stacked between second face and base is less, can reduce the extrusion intensity of the insulating layer of electronic component to the voltage line that sets up between second face and the base of circuit board to reduce the insulating layer of voltage line and receive the probability that the problem of damage takes place because of the extrusion, and then can reduce the voltage line and appear the probability that the short circuit problem takes place because of the damage, improve the reliability of use of guide rail ammeter. In one possible design, the wire arrangement structure is a through hole penetrating through the body along a first direction, and the first direction is an arrangement direction of the first surface and the second surface. Through the scheme, the through hole penetrates through the body along the first direction, the first surface is communicated with the second surface, and when the first surface is communicated with the second surface, the second end of the voltage line can penetrate through the through hole to be connected with the welding structure arranged on the first surface. In one possible design, the aperture of the via is larger than the diameter of the voltage line. Through the scheme, the diameter of the through hole can be larger than that of the voltage line, the voltage line can move in the through hole along the first direction after passing through the through hole, so that the difficulty in stretching the voltage line to the welding structure after passing through the through hole can be reduced, the welding connection between the second end of the voltage line and the welding structure is more convenient, and the cost of the voltage line during connection can be reduced.
