Description

Plug for terminal connection of electrical installation and wire module comprising the same The present invention relates to a plug and a wire module including the same. More specifically, the present invention relates to a plug for connecting terminals of an electrical installation and a wire module including the same. When testing electrical equipment, such as substations, a tester must be connected to the substation. In this case, the tester is connected to the substation by gripping the substation's terminals with the clips located at the ends of the tester's connecting wires. In other words, the tester is connected to the substation by gripping the substation's terminals with alligator clip-shaped clips. FIG. 7 schematically illustrates the state of connecting a clamp (C) according to the prior art to a terminal (T) of an electrical installation (E). As shown in FIG. 7, the clamp (C) can be electrically connected by clamping it to the terminal (T). However, since this connection is not secure, the clamp may come loose and come into contact with other wires, causing contact. In addition, in the event of contact in an open circuit, there is a risk of power outage due to the opening of the circuit breaker. FIG. 1 is a schematic diagram of the usage state of a wire module according to one embodiment of the present invention. Figure 2 is a schematic front-side exploded perspective view of the wire module of Figure 1. Figure 3 is a schematic cross-sectional view of an adapter unit cut along line III-III of Figure 2. Figure 4 is a schematic rear exploded perspective view of the wire module of Figure 1. Figure 5 is a schematic partial connection diagram of the wire module of Figure 2. Figure 6 is a schematic diagram of the combined state of the wire module of Figure 5. FIG. 7 is a schematic diagram of a state in which a clamp according to the prior art is connected to a terminal of an electrical facility.
