DETAILED DESCRIPTION

[0023] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example

[0025] like Figure 1 As shown, the utility model proposes a connector for an electric meter box, comprising a base 1, and a plurality of plug connectors 2 fixedly mounted on the base 1, the plug connectors being used to be plugged into the electric meter, and mounting holes 101 are provided on both sides of the base 1, and the mounting holes 101 are used to fix the base 1 in the electric meter box.

[0026] like Figure 2 and Figure 5-6 As shown, it also includes a power-off protection mechanism, which is installed on the base 1. The power-off detection mechanism detects whether it is connected to the electric meter and controls the on-off state of the power supply according to whether it is connected to the electric meter. An installation cavity 4 is provided in the base 1. The power-off protection mechanism includes a detection drive component and an execution component, and the execution component is located in the installation cavity 4. The detection drive component detects whether it is connected to the electric meter and provides power to the execution component. The execution component performs power on and off operations after being driven by the detection drive component.

[0027] Among them, the execution component includes multiple groups of connectors fixedly installed in the installation cavity 4, and the multiple groups of connectors correspond one-to-one to the multiple plug connectors. One group of connectors includes a telescopic rod 5 fixedly installed at the top and bottom of the installation cavity 4, an electrical connector 501 fixedly installed on the telescopic rod 5, and a first spring 502 fixedly installed on the electrical connector 501 and inside the installation cavity 4. The execution component also includes multiple connectors 503 slidably installed in the installation cavity 4 and a driving rod 504 fixedly installed on the multiple connectors 503. The multiple connectors 503 correspond one-to-one to the multiple groups of connectors. The two electrical connectors 501 on the same group of connecting heads do not contact each other, which is an open circuit state, and the electrical connectors are made of conductive material. When the connecting head 503 moves between the two electrical connectors 501, the connecting head 503 will contact the two electrical connectors 501, and the connecting head is made of conductive material, so that the circuit can be connected, and under the action of the first spring 502, the electrical connectors 501 on the upper and lower sides can apply pressure to the connecting head 503, so that the connecting head 503 and the two electrical connectors 501 are firmly fixed.

[0028] Among them, the detection drive assembly includes a detection rod 3 slidably installed on the base 1, a rubber head 301 fixedly installed on the detection rod 3, a support block 302 fixedly installed on the detection rod 3, a second spring 303 fixedly installed on the support block 302 and fixedly connected to the base 1, a triangular block 304 fixedly installed on the detection rod 3, a mounting seat 305 fixedly installed on the driving rod 504, and a roller 306 rotatably installed on the mounting seat 305, the roller 306 abuts against the triangular block 304, one end of the driving rod 504 is fixedly installed with a third spring 307, and the other end of the third spring 307 is fixedly connected to the inner wall of the mounting cavity 4. When not connected to the electric meter, the detection rod 3 is higher than the plug connector 2 under the action of the second spring 303. At this time, under the action of the third spring 307, the driving rod 504 drives the connecting head 503 to separate from the electrical connector 501. When connected to the electric meter, the rubber head 301 will abut against the bottom of the electric meter, thereby driving the detection rod 3 to move downward. At this time, the second spring 303 is compressed, and the downward movement of the detection rod 3 will drive the triangular block 304 to move downward. The triangular block 304 and the driving rod 504 are staggered. The downward movement of the triangular block 304 will not be affected by the driving rod 5 04 causes interference. When the triangular block 304 moves downward, the triangular block 304 will squeeze the roller 306 and apply a lateral force to the roller 306, thereby driving the roller 306 to move to the left, and then driving the driving rod 504 to move to the left. At this time, the third spring 307 is stretched, thereby driving the multiple connectors 503 to contact the electrical connector 501, thereby forming a closed loop. When the electric meter is unplugged, under the action of the second spring 303 and the third spring 307, the driving rod 504 and the detection rod 3 will be reset, thereby cutting off the power.

[0029] like Figure 4As shown, it also includes a locking mechanism for fixing the wires, the locking mechanism includes a plurality of wire holes 6 provided at the bottom of the base 1, a plurality of bolts 601 rotatably mounted on the base 1, the plurality of wire holes 6 correspond to the plurality of plug connectors 2 one by one, the plurality of bolts 601 correspond to the wire holes 6 one by one and are connected to the wire holes 6, a first wiring piece 602 is rotatably mounted on the bolts 601, a second wiring piece 603 is fixedly mounted in the wire holes 6, and both the first wiring piece 602 and the second wiring piece 603 are made of conductive materials. When wiring, the wire is placed between the first wiring piece 602 and the second wiring piece 603 through the wire holes 6, and then the bolts 601 are rotated to drive the first wiring piece 602 to move in the direction close to the second wiring piece 603, thereby pressing and fixing the wire, thereby completing the fixing of the wire.

[0030] like Figure 4 As shown, the plurality of second wiring pieces 603 are electrically connected to first wires 7, which correspond one-to-one to and are electrically connected to the plurality of telescopic rods 5 located at the lower side of the installation cavity 4. The plurality of plug connectors 2 are electrically connected to second wires 8, which correspond one-to-one to and are electrically connected to the plurality of telescopic rods 5 located at the upper side of the installation cavity 4. The current is transmitted to the plug connector 2 through the first wires 7 and the second wires 8.

[0031] Working principle: when not connected to the electric meter, the detection rod 3 is higher than the plug connector 2 under the action of the second spring 303. At this time, under the action of the third spring 307, the driving rod 504 drives the connector 503 to separate from the electrical connector 501. At this time, it is in a circuit-breaking state. When connected to the electric meter, the rubber head 301 will abut against the bottom of the electric meter, thereby driving the detection rod 3 to move downward. At this time, the second spring 303 is compressed, and the downward movement of the detection rod 3 will drive the triangular block 304 to move downward. The triangular block 304 will squeeze the roller 306 and apply a lateral force to the roller 306, thereby driving the roller 306 to the left. The third spring 307 is stretched at this time to move the connector 503 between the two electrical connectors 501. The connector 503 will contact the two electrical connectors 501, so that the circuit can be connected. Under the action of the first spring 502, the electrical connectors 501 on the upper and lower sides can apply pressure to the connector 503, so that the connector 503 and the two electrical connectors 501 are firmly fixed. When the electric meter is pulled out, the second spring 303 and the third spring 307 will reset the drive rod 504 and the detection rod 3, so as to cut off the power.
