Description

Technical Field

[0001] The utility model relates to a guide rail type electric energy meter, in particular to a leakage-proof three-phase guide rail type electric energy meter, belonging to the technical field of electric energy meters. Background Art

[0002] An energy meter is an instrument used to measure electrical energy. It is also called an electric meter, a fire meter, or a kilowatt-hour meter. It refers to an instrument that measures various electrical quantities. When using an energy meter, please note that in the case of low voltage (no more than 500 volts) and small current (tens of amperes), the energy meter can be directly connected to the circuit for measurement. In the case of high voltage or high current, the energy meter cannot be directly connected to the circuit and must be used in conjunction with a voltage transformer or a current transformer.

[0003] After the wiring terminals of the existing three-phase rail-type electricity meters are connected to the external power grid, the connection of the wiring terminals is exposed to the outside world without wrapping. If the air is humid and there are some induced leakage factors, there will be leakage hazards at the connection of the wiring terminals. At the same time, when the terminals and the wiring heads are not completely tightened, the wiring heads may loosen and slip, causing leakage accidents. Therefore, we need to upgrade and transform on the basis of existing technologies. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a three-phase rail-type electric energy meter with leakage protection. The device can protect the wiring terminals and clamp and tighten the connected wiring heads, which solves the technical problem that the connection parts of the wiring terminals in the prior art are exposed to the outside world without being wrapped. If the air is humid and some induced leakage factors are added, the connection parts of the wiring terminals will have leakage hazards. At the same time, if the terminals and the wiring heads are not sufficiently tightened, the wiring heads will loosen and slip, causing leakage accidents.

[0005] In order to solve the above problems, the following technical solutions are provided:

[0006] A leakage-proof three-phase rail-type electric energy meter is designed, comprising a meter body, wherein wiring terminals are fixedly connected at the upper and lower ends of the meter body, a terminal slot is arranged inside the wiring terminal, a fixed slot is arranged at the bottom of the terminal slot, a clamping block is slidably connected inside the fixed slot, a side plate is fixedly connected to the outer side of the wiring terminal, a baffle slot is arranged inside the side plate, the baffle slot passes through the top end of the wiring terminal, a slide rod is slidably connected inside the baffle slot, a slide slot is arranged on the back side of the meter body, and a slide rail is slidably connected inside the slide slot.

[0007] Furthermore, a conductive terminal is fixedly connected inside the terminal slot, a top of the conductive terminal is fixed to an inner top of the wiring terminal, and a fixing nut is rotatably connected to the front of the conductive terminal.

[0008] Through the above technical solution, the circuit is connected by connecting the wiring head in the power line to the conductive terminal and clamping and fixing it with a fixing nut.

[0009] Furthermore, a wire hole is provided inside the clamping block, and a tightening groove is provided on the top of the wire hole.

[0010] Through the above technical solution, the power line to be connected is clamped into the wire hole, and the clamping block is clamped in the fixed notch, so as to achieve fixed clamping of the connected power line.

[0011] Furthermore, an isolation baffle is fixedly connected to one end of the slide rod, and the isolation baffle fits exactly inside the side plate. A clamping block is fixedly connected to one side of the side plate.

[0012] Through the above technical solution, the isolation baffle can be attached to the surface of the terminal through the card block. At the same time, due to the limitation of the card block, the isolation baffle cannot be separated from the surface of the terminal without a large external force, thereby protecting the internal terminals of the terminal.

[0013] Furthermore, a display panel is fixedly provided on the front of the meter body, and a control button is provided at one end of the front of the meter body.

[0014] Through the above technical solution, the display panel facilitates the real-time observation of the internal information of the electric energy meter, and the control button can realize the internal circuit control of the electric energy meter.

[0015] Furthermore, a spring buckle is fixedly connected to the side of the meter body, a spring lock tongue is slidably connected inside the spring buckle, one end of the bottom of the spring lock tongue is fitted at the top of the slide rail, and an anti-slip rubber pad is provided at the bottom of the spring lock tongue.

[0016] Through the above technical solution, the spring buckle is pressed so that the internal locking tongue fits tightly against the top of the slide rail, thereby fixing the electric energy meter on the slide rail.

[0017] Furthermore, the clamping block and the isolation baffle are made of insulating materials, and the conductive terminal and the fixing nut are made of copper material with good conductive properties.

[0018] Through the above technical solution, the insulating plate effectively blocks leakage between the terminal and the line joint, and the copper material of the conductive terminal achieves better current transmission.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] 1. In the utility model, after the meter body is slid into the slide rail along the slide groove, the spring buckle is pressed to fix it at one end of the slide rail, the isolation baffle is moved to separate it from the surface of the terminal, and then the isolation baffle is rotated along one end of the slide rod to push the isolation baffle into the baffle groove, and then the clamping block is taken out from the fixed notch, the power line to be connected is clamped into the wire hole, and the power connector is connected to the conductive terminal, and then the clamping block is pushed into the fixed notch, and then the isolation baffle is pulled out to be clamped in the clamping block and fit on the surface of the terminal again to complete the line connection installation. The above-mentioned isolation baffle can realize the isolation and protection of the lines and conductive terminals connected inside the baffle groove, and avoid leakage accidents under certain circumstances;

[0021] 2. In the utility model, the clamping block can clamp and fix the power line at the connection, so as to prevent the power line connector from loosening at the connection with the fixing nut, and from falling off and causing leakage;

[0022] With reference to the following description and drawings, specific embodiments of the present invention are disclosed in detail, indicating the manner in which the principles of the present invention can be adopted. It should be understood that the embodiments of the present invention are not limited in scope.
