Problems solved by technology

[0003] At present, the commonly used joint junction box generally connects the secondary line or the wire of the electric energy meter into the joint junction box through the wiring through hole arranged on the side wall of the box body, and does not set any protective device and compression at the wiring through hole. According to the investigation of the inventor, it is found that this kind of joint junction box is very easy to steal electricity through the wiring through hole, resulting in less electricity, and causing a lot of economic losses to the power supply company.
Moreover, the wire is directly connected to the terminal of the joint junction box. When the wire is pulled or the position of the wire is changed, because the stress point of the wire is located at the connection between the wire and the terminal, it is easy to cause the wire to fall off, so that the wire and the terminal connection is very unstable

Abstract

The present invention provides a joint junction box and an electric energy metering box and belongs to the electrical equipment field. The joint junction box is installed in the electric energy metering box; the joint junction box comprises a box body, a cover body, a wiring device and a locking device; in a wiring process, secondary wires or conductors are connected onto wiring blocks through wiring holes; the secondary wires or conductors are pressed by pressing blocks, and at the same time, the wiring holes are blocked through the pressing blocks; and the cover body is locked on the box body through the locking device. Since the wiring holes are blocked, and the cover body is locked on the box body through the locking device, and therefore, the interior of the joint junction box can be isolated from outside space, and electricity stealing behaviors can be effectively prevented; protruding blocks on the pressing blocks extend into the wiring holes, so that the secondary wires or the conductors can be pressed, when the secondary wires or the conductors are pulled and shaken due to the effect of an external force, force bearing points are located in the wiring holes, and therefore, the anti-pulling capability of the secondary wires or the conductors can be enhanced, and the stability of wiring can be improved.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a joint junction box and an electric energy metering box. Background technique [0002] The joint junction box is an important wiring device in the circuit connection. It is a special junction box for electric energy measurement. It is widely used in the power industry. The joint junction box is used to connect the meter or instrument to the secondary circuit in operation. Complete the test or verification of different projects. At present, the function of the combined junction box in the circuit connection is also mainly to connect the secondary wires drawn from the transformer to the terminals of the electric energy meter after being connected in series and parallel through the connecting terminals of the combined junction box. [0003] At present, the commonly used joint junction box generally connects the secondary line or the wire of the electric energy meter into the jo...
