Embodiment
[0046] This embodiment provides a hand-operated household contactor, which includes a housing 5, an electromagnetic mechanism, a contact support 3, a gear locking structure and a hand-operated power-off structure.
[0047] Housing 5, such as Figure 14 As shown, it has a long hole 19 on its top, and two buckle grooves 17 on one side of the long hole 19, and the two side walls in the width direction of the long hole 19 have buttons for allowing The notch 30 that the push button part 21 of 6 protrudes from the inside of the housing 5, and the step 31 that can abut against the push button part 21, the side plate 44 of the housing 5 has a stop formed on its inner surface Block 45. The casing 5 is provided with a first limiting block 13 , the first limiting block 13 is located on a side of the connecting rod 7 away from the first driving block 8 and abuts against the connecting rod 7 . When the button part 6 is assembled, the push button part 21 is first loaded into the gap 30, a...

The invention provides a hand-operated household contactor, and the contactor comprises an electromagnetic mechanism which comprises a coil, a static iron core, and a movable iron core which is in linkage with a contact support; the contact support moves in the Y-axis direction of the shell and can be directly driven by the button piece, and the contact support has a switching-off state and a switching-on state under the power-off state of the coil; the button piece moves in the X-axis direction of the shell, a reversing structure is arranged between the button piece and the contact support, the reversing structure is suitable for converting movement of the button piece in the X-axis direction into movement of the contact support in the Y-axis direction, and the button piece is provided with a first gear corresponding to an opening state and a second gear corresponding to a closing state when the coil is in a power-off state. As the button piece can directly drive the contact support to move, compared with the mode that the button piece needs a gear to drive the contact support to act in the prior art, only the button piece and the contact support are needed, the structure is simpler, the assembly efficiency is improved, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of low-voltage electrical appliances, in particular to a hand-operated household contactor. Background technique [0002] The contactor is widely used in the control circuit of the fire pump. When a fire occurs, the controller used to control the fire pump contactor can control the conduction of the loop where the coil is located, and the current flowing through the coil generates a magnetic field to make the static iron core attract the moving iron. The core, the moving iron core drives the contact to support the action, so that the main contact of the contactor is closed, so that the main circuit of the fire pump can be connected, so that the fire pump can work normally; however, because the fire is likely to cause the controller to fail The circuit where the coil is located cannot be turned on. When the coil is powered off, the moving iron core loses its power source, which causes the contactor to fail to...
