Detailed Description

Example 1

The press type power-off switch comprises a plastic box 1, wherein a spring piece hole 2 and two through holes 3 are formed in the bottom of the plastic box 1 respectively, spring pieces 4 are inserted into the spring piece hole 2 respectively, a bent section 5 is formed in the upper ends of the spring pieces 4, the inner sides of the bent sections 5 of the spring pieces 4 are in contact, the lower ends of the spring pieces 4 are connected with a PCB 6, and the bent sections 5 of the spring pieces 4 are connected with an upper cover 8 of an electric energy meter through separating blocks 7.

The separating block 7 and the upper cover 8 of the electric energy meter are integrally formed by injection molding.

The spring piece 4 is a copper sheet.

When in use, the specific working principle is as follows: during assembly, the PCB is fixed in the lower shell of the electric energy meter, the spring piece 4 at the lower end of the switch is inserted into the PCB, the PCB is provided with a corresponding circuit structure, the upper cover 8 of the electric energy meter is clamped on the lower shell of the electric energy meter, and the separating block 7 is inserted into the bending section 5 of the spring piece 4, so that the bending sections 5 of the two spring pieces 4 are separated, the two spring pieces 4 are not contacted, and a loop is not formed; when stealing the electricity or uncapping when overhauing, extract electric energy meter upper cover 8 to make the spacer block 7 extract, the curved segment 5 contact of two spring leaf 4, thereby make two spring leaf 4 contacts, form the return circuit, give PCB circuit board upper sensing device with the signal transmission, leave the record of uncapping, make things convenient for the later stage to look over, thereby realize detecting uncapping and the function of theftproof electricity.

The push type power-off switch of this embodiment, through the structure setting of separation block and spring leaf, the equipment is convenient, and can realize uncapping and detect and theftproof electricity.
