专利汇可以提供Terminal structure for watt-hour meter专利检索,专利查询,专利分析的服务。并且PURPOSE: To replace a watt-hour meter easily by separating a terminal block from a watt-hour meter body and forming a switch enable to switch interruption, connection and short-circuiting on the terminal block.
CONSTITUTION: The terminal block 20 is separated from the watt-hour meter body 10 and pin terminals 11W13 to be electrically connected to the block 20 and a testing short-circuit chip 14 are formed on the body 10. On the other hand, watt-hour meter connecting terminals 21W23 to be connected to the termi nal pins 11W13 of the body 10, power supply line connecting terminals 25, 26, load line connecting terminals 27, 28, and a change-over switch 24 are formed on the block 20. The switch 24 is constituted so as to switch three states; inter ruption, connection and short-circuit. To replace the body 10, the switch 24 is turned to the short-circuit position, electric power supplied through the power supply lines is directly supplied to the load lines without passing the body 10 and then the body 10 is separated from the block 20. Then, a new body 10 is fitted again and the switch 24 is turned on, so that the replacement of the body 10 can be completed without interrupting power supply.
