In the above embodiment, as the flipping handle 200 is rotated, different outer circumferential surfaces of the cam 220 are brought into contact with the driving pin 310. When the conductor 221 and the driving pin 310 are brought into contact, the conductor 221 and the driving pin 310 are electrically connected to each other. When the conductor 221 is disengaged from the driving pin 310, the conductor 221 and the driving pin 310 are disengaged from each other. In the actual use process, the electric meter and the external circuit can be respectively connected with the transmission pin 310 and the conductor 221, i.e. the electric meter is controlled to be disconnected or connected by rotating the turning handle 200.
Based on the above embodiments, in some preferred embodiments, the outer surface of the conductor 221 is arc-shaped, and the end of the driving pin 310 near the cam 220 has an arc surface, so that the driving pin 310 fits the conductor 221. Since the conductor 221 and the driving pin 310 are attached to each other, the contact area between the driving pin 310 and the conductor 221 is increased, and thus the over-current area between the conductor 221 and the driving pin 310 is increased.

The spring 321 urges the drive pin 310 against the cam 220 such that the drive pin 310 compresses the drive pin 310.
In some preferred embodiments, the mounting base 100 is provided with a plug hole 130, and the plug hole 130 communicates with the transmission hole 120. Wires of an external circuit are led into the mount 100 through the jack 130 so as to perform a wiring operation on the wires and the ammeter wiring seat.
In some preferred embodiments, the electricity meter wiring seat further includes a protective sleeve 400, the protective sleeve 400 includes a plug portion 410 and a clamping portion 420, the plug portion 410 is inserted through the plug hole 130, the clamping portion 420 abuts against the mounting seat 100 to limit the plug portion 410 to completely pass through the plug hole 130, and the protective sleeve 400 further has a threading hole 430 passing through the plug portion 410 and the clamping portion 420.
In the above embodiment, the wire is first threaded into the threading hole 430, so that the protection sleeve 400 is sleeved over the wire. The plugging portion 410 can be inserted into the plugging hole 130, and the wires can be inserted into the plugging hole 130. By utilizing the electricity larceny prevention protection structure provided by the utility model, the gap between the lead and the inner wall of the plug hole 130 can be blocked by utilizing the protective sleeve 400, so that illegal molecules can be prevented from carrying out electricity larceny operation through the gap.
The plugging portion 410 includes a plurality of claws 411, and the plurality of claws 411 encircle the threading hole 430. When the plugging portion 410 is separated from the plugging hole 130, the wire is threaded through the threading hole 430, and the wire can be moved relative to the plugging portion 410, so as to adjust the length of the wire threaded through the threading hole 430. When the plugging portion 410 is inserted into the plugging hole 130, the claw 411 deforms along the radial direction of the plugging hole 130, and the wire is clamped by the claw 411, so as to limit the wire to slide relative to the protective sleeve 400.
Based on the above embodiments, in some preferred embodiments, the inner wall of the claw 411 has an arc surface so that the inner wall of the claw 411 fits the wire. Because the inner wall of the clamping jaw 411 is an arc surface, the inner wall of the clamping jaw 411 is attached to the outside of the wire, so that the contact area between the clamping jaw 411 and the wire can be increased, and the wire can be more effectively limited to slide relative to the clamping jaw 411.
In some preferred embodiments, the inner wall of the threading hole 430 has a plurality of limiting portions 440, and the limiting portions 440 allow the core of the wire to pass through and block the insulation sheath of the wire from passing through. In the above embodiment, the limiting portion 440 is used to reduce the inner diameter of a portion of the threading hole 430, so that the inner diameter of the portion only allows the core of the wire to pass therethrough, but the insulating sheath of the wire is blocked from passing therethrough, so that the end of the insulating sheath only needs to be pressed against the limiting portion 440, so as to determine the length of the core passing through the threading hole 430.
In addition, the embodiment of the utility model also provides an ammeter box, which is provided with the ammeter wiring seat.
Under the action of the elastic member 320, the driving pin 310 presses the cam 220, and the first mounting key (not shown) is rotatably inserted into the first rotating section 112 from the first introducing section 111, or the second mounting key 210 is rotatably inserted into the second rotating section (not shown) from the second introducing section (not shown) and rotatably inserted into the second rotating section (not shown). Further, the toggle handle 200 may be rotated such that the rotating cam 220 pushes the driving pin 310 to slide. By utilizing the ammeter wiring seat provided by the utility model, the turnover handle 200 can be rotatably arranged on the mounting seat 100 through the mutual matching of the first mounting key (not marked in the figure) and the second mounting groove (not marked in the figure) or the mutual matching of the second mounting key 210 and the first mounting groove 110, so that the rotary handle is not required to be arranged by means of a metal rotary shaft. And then increases the electric clearance of twist grip, has reduced the creepage risk of twist grip department.
The above-described embodiments of the present utility model do not limit the scope of the present utility model. Any of various other corresponding changes and modifications made according to the technical idea of the present utility model should be included in the scope of the claims of the present utility model.
