The detection circuit is a detection circuit in which the electronic components are connected in series, and the detection circuit is connected to the two connection bodies to form a series closed circuit. The connection between the two connecting bodies may be a connection between different conductors or a connection between the same conductors, and is not specifically described here.
The first connection terminal is connected with the first connection body in a connection mode which can be connected according to the type of the connection terminal, for example: when binding post was the alligator clip, can press from both sides the alligator clip on first connector, the connector probably parcel has protective colloid, presss from both sides the mouth sharpness because of the alligator clip, can press from both sides the protective colloid of broken first connector for the alligator clip is connected with first connector electrical connection.

The grounding down lead is a metal conductor for connecting the electrical equipment and the grounding body, is made of galvanized steel, is coated with thicker insulating paint on the surface, and has no depression, no convex edge, no corrosion, uniform color and uniform thickness.

The implementation of the calculation may also be in other forms and will not be described in detail here.
RxThe resistor consists of two parts, namely a contact resistor and a lead resistor. Contact resistance refers to the ratio of the potential difference across the contact surface to the current through the contact surface. The wire at the junction of the two connectors is very short and the wire resistance is much smaller than the contact resistance, so the wire resistance is negligible. Namely RxMay be approximately equal to the contact resistance. The contact resistance can indirectly reflect the contact condition between the two connectors, and the larger the contact area between the two connectors is, the less the surface impurities are, the smaller the contact resistance is, and the contact condition between the two connectors can be reflectedThe better the conductivity. The resistance value of the contact resistance is generally less than 10m omega, the contact resistance between the two connectors only needs to be detected at regular time in the process of maintaining the circuit, the firmness and the reliability of the connection between the two connectors can be known according to the detected resistance value of the contact resistance, and whether the open circuit exists between the two connectors can be judged through the contact resistance.
