Abstract
This terminal block for three-phase electric energy meter disclosed in the utility model, comprises terminal block body, the manganese copper diverter of belt current terminal, the voltage terminal of band cable.Have preformed groove in terminal block body, the assembly parts of current terminal and manganese copper diverter and voltage terminal are individually fixed in corresponding preformed groove.Cable is welded in one end of voltage terminal, makes voltage terminal and cable form integral structure improve efficiency of assembling by the heat-shrinkable T bush that the welding end of voltage terminal is fixed in one end, the other end entangles cable.The assembly parts of current terminal and manganese copper diverter and voltage terminal are all hidden in terminal block body, the volume of terminal block is reduced, its taking up room in electric energy meter is reduced, improves the space availability ratio of electric energy meter and the volume of whole table can be reduced, cost-saving.Voltage terminal is hidden in terminal block body the proof voltage problem also solved between PCBA and voltage terminal, and current terminal is hidden in terminal block body can also be connected to copper material.
Description
Technical field
The utility model relates to a kind of three-phase electric energy meter, is specifically related to a kind of terminal block structure of three-phase electric energy meter.
Background technology
At present, the terminal block of three-phase electric energy meter, because of voltage terminal projecting terminal row body, between PCBA and voltage terminal, proof voltage existing problems, generally increase Plastic securing panel, PCBA and voltage terminal are separated, simultaneously for avoiding voltage terminal, current terminal also can cut greatly by projecting terminal row body one, and very waste copper material, the cost of whole table is very high.
Utility model content
The purpose of this utility model is to provide a kind of terminal block that is little, that reduce costs that takes up room.
This terminal block for three-phase electric energy meter disclosed in the utility model, comprises terminal block body, the manganese copper diverter of belt current terminal, the voltage terminal of band cable.Have preformed groove in terminal block body, the assembly parts of current terminal and manganese copper diverter and voltage terminal are individually fixed in corresponding preformed groove.
Described cable is welded in one end of described voltage terminal, makes voltage terminal and cable form integral structure by the heat-shrinkable T bush that the welding end of voltage terminal is fixed in one end, the other end entangles cable.
The utility model by arranging preformed groove in terminal block body, the assembly parts of current terminal and manganese copper diverter and voltage terminal are all hidden in terminal block body, the volume of terminal block is reduced, its taking up room in electric energy meter is reduced, improve the space availability ratio of electric energy meter and the volume of whole table can be reduced, cost-saving.
Voltage terminal is hidden in terminal block body the proof voltage problem also solved between PCBA and voltage terminal, and current terminal is hidden in terminal block body can also save copper material.
Integral structure between cable and voltage terminal can improve efficiency of assembling.
In sum, the utility model by simplifying structure, save take up room, material, decrease assembly process, thus realize the object that reduces costs.
Accompanying drawing explanation
Fig. 1 is the assembly structure schematic diagram of box at the bottom of the utility model and three railway carriage or compartment electric energy meters.
Fig. 2 is the assembly structure schematic diagram of voltage terminal, cable and heat-shrinkable T bush.
Embodiment
As shown in Figure 1 and Figure 2, this terminal block for three-phase electric energy meter disclosed in the utility model, comprises terminal block body 1, the manganese copper diverter 2 of belt current terminal 21, the voltage terminal 3 of band cable 31.Cable 31 is welded in one end of voltage terminal 3, makes voltage terminal 3 and cable 31 form integral structure by the heat-shrinkable T bush 32 that the welding end of voltage terminal 3 is fixed in one end, the other end entangles cable 31.
Have preformed groove in terminal block body 1, manganese copper diverter 2 and the voltage terminal 3 of belt current terminal 21 are individually fixed in corresponding preformed groove.During assembling, the voltage terminal 3 of first mounting strap cable 31, then the manganese copper diverter 2 of mounting strap current terminal 21, voltage terminal 3, current terminal 21 and manganese copper diverter 2 are all hidden in terminal block body 1, and voltage terminal 3 is drawn by cable 31, current terminal 21 is drawn by the lead-in wire of manganese copper diverter 2 and is connected with the PCBA of electric energy meter.
Carry out the timing of electric energy meter integral installation, terminal is arranged the relevant position be assembled on end box, then PCBA is assembled, refill and mix box and end cap.
