Embodiment Construction

[0026] FIG. 2 shows a schematic circuit diagram of the current overload warning socket according to the present invention. The socket includes a plug 40, which has two input terminals 40a, 40b and is electrically connected to two power lines 14d, 14c respectively; a reed relay 16; a warning device 17; and 3 sets of parallel female plug terminals (sockets) 42 , 44, 46. The feature of the present invention is that the reed relay 16 has a reed switch 24 and a conductive coil 16c wound on the reed switch 24, and the coil 16c is connected in series between the power line 14d and the plug terminals 42, 44, 46 to form a loop . The reeds 24 and 26 of the reed switch 24 are connected to the warning device 17 and the power line 14c to form another loop.

[0027] Electrical energy from the power source reaches the two power cords 14d, 14c via the two input terminals of the plug 40 . The coil 16c of the reed relay 16 is connected to the power line 14d. The number of turns of the coil ...

Abstract

A electrical socket that provides current overload warning function, includes at least one plug socket; a pair of input terminals, for supplying power to the plug socket after the connection; a magnetic reed relay, which comprises a conductive coil and a dry-reed tube. The said conductive coil is connected in series between one of the two input terminals and the plug socket, and the said dry-reed tube connects an warning apparatus, accordingly when the total consumed current size of one or more loads connected to the plug socket, and flowing through said conductive coil exceeds the operating current value that magnetic red relay sets, the magnetic contact of the dry-reed tube is drived to work and to start the warning apparatus, so as to send the warning immediately.

Description

technical field [0001] The invention relates to a socket with a current overload warning function, especially a socket with a special magnetic reed relay to activate the warning device to issue a warning. Background technique [0002] The prior art socket shown in Figure 1 comprises upper and lower housings 10a, 10b held together by screws 15a. The two socket copper sheets 11a are fixed on the lower casing 10b with screws 12a, and one end of each socket copper sheet 11a is directly connected to the end of the power line 14a with screws 13a. This kind of socket does not have an overload warning function, so users of this kind of socket use the socket without knowing whether the socket has been overloaded, and therefore this kind of socket is prone to danger when using it without knowing that it has been overloaded. For example, the socket is overheated and burned. [0003] Therefore, when the user uses the socket, it is desirable for the user to immediately know whether the...
