Live wire terminals 11 are provided at both ends of the live wire housing 10, and neutral wire terminals 21 are provided at both ends of the neutral wire housing 20. A control mechanism is included in the live wire housing 10, and the control mechanism is used to control the two live wire terminals 11 to disconnect. A socket 50 for connecting electricity is provided on the control mechanism, and the live wire socket of the socket 50 is connected to a live wire terminal 11 through the first elastic member 30; the live wire housing 10 and the neutral wire housing 20 are connected side by side, and a power inlet 12 is provided on the side of the live wire housing 10 facing the neutral wire housing 20, and a power outlet 22 is provided on the side of the neutral wire housing 20 facing the live wire housing 10. One end of the second elastic member 40 is connected to the neutral wire socket of the socket 50, and the other end passes through the power inlet 12 and the power outlet 22 to be connected to a neutral wire terminal 21. The control mechanism of the present application uses a socket 50, a first elastic member 30 and a second elastic member 40 to obtain power from the live terminal 11 and the neutral terminal 21 respectively. When producing, as long as the components are assembled on the housing, the function of obtaining power for the control mechanism can be realized. The control structure is a structure for judging circuit overload, short circuit or leakage, and has the function of automatically disconnecting the circuit, which is a prior art.
[0022] The first elastic member 30 includes a first insertion section 31, a first connection section 32 and a first elastic section 33. The first insertion section 31 is inserted into the neutral line socket of the socket strip 50. One end of the first connection end is connected to the first insertion section 31, and the other end is connected to the first elastic section 33. The first elastic section 33 is used to contact the live wire terminal 11. The socket strip 50 is disposed in the live wire housing 10, and it can be connected to the live wire terminal 11 through the first elastic member 30, or the control mechanism can be directly connected to the live wire terminal 11.

The first elastic member 30 is made of conductive material as a whole, and the first connecting section 32 and the first elastic section 33 are flat. When the first elastic section 33 contacts the live terminal 11 and the angle between the first elastic section 33 and the first connecting section 32 becomes smaller, the first elastic section 33 will generate elastic force to contact the live terminal 11, thereby contacting the live terminal 11 more closely.

The second insertion section 43 is connected to the live wire jack of the socket strip 50 through the power input port 12, and the second elastic section 45 extends into the neutral wire housing 20 through the power extraction port 22 and abuts against the neutral wire terminal 21. When taking power at the live wire terminal 11 and the neutral wire terminal 21 on the same side, the power input port 12 is opened at the first-end live wire terminal 11 of the live wire housing, and the power extraction port 22 is opened at the first-end neutral wire terminal 21 of the neutral wire terminal 21, so that the power extraction ports 22 are opened face to face. The socket strip 50 can be directly connected to the neutral wire terminal 21 in abutment through the second elastic member 40. The second elastic section 45 of the second elastic member 40 can abut against the neutral wire terminal 21 and generate a certain force on the neutral wire terminal 21, so as to be in closer contact with the neutral wire terminal 21. Specifically, the second elastic member 40 is made of a conductive material as a whole, and the second elastic section 45 is spiraled into a spring shape, so as to have a certain elastic force.
[0025] Embodiment 2: As Figure 12 shown in the figure, the power input port 12 is opened on the side of the live wire housing 10 near the first-end live wire terminal 11, and the power extraction port 22 is opened on the side of the neutral wire housing 20 near the second-end neutral wire terminal 21. A power extraction groove 23 is also opened on the neutral wire housing 20. One end of the power extraction groove 23 is connected to the power extraction port 22, and the other end extends to the power input port 12; the second elastic member 40 is a long elastic member 42, and the long elastic member 42 includes a second insertion section 43, a second extension section 44 and a second elastic section 45 which are connected in sequence.

The second elastic member 40 is made of a conductive material as a whole. One end of the second elastic member 40 is the second insertion section 43 directly inserted into the socket strip 50, and the other end is the second elastic section 45 abutting against the neutral wire terminal 21. The second elastic section 45 is spiraled into a spring shape, so that it can abut against the neutral wire terminal 21 and apply a force to the neutral wire terminal 21, so as to ensure close contact with the neutral wire terminal 21.
[0026] The methods of Embodiment 1 and Embodiment 2 can be adopted simultaneously.
[0027] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model.
