[0033] like Figure 1-5 As shown, this embodiment provides a two-pin female plug 100 with the function of switching on and off a wire 3, including a shell 1, the shell 1 is a plastic shell 1, two metal springs 2 are symmetrically arranged inside the shell 1, and the movable ends of the two metal springs 2 are arranged against each other. One end of the shell 1 is provided with a wire inlet 11, a section of the wire 3 of the external circuit is cut off, and then passed through the wire inlet 11, one end of the two wires 3 is connected to the two metal springs 2 respectively, and one end of the shell 1 is provided with two sockets 12 for connecting to a male plug 200. During use, the female plug 100 in the present application can be connected to the circuit by stripping a wire 3 in the circuit, and the two broken ends of the wire 3 are respectively passed through the wire inlet 11 and connected to the metal spring 2. When the male plug 200 is not inserted, the two metal springs 2 are in contact with each other to achieve conduction. At this time, the female plug 100 is equivalent to a wire 3; when the male plug 200 is inserted through the jack 12, the male plug 200 separates the two metal springs 2. At this time, the female plug 100 is in a disconnected state, and the male plug 200 can be connected to a switch 300 for use, and the on and off are controlled by the switch 300 to achieve the control function.

[0034] Specifically, the metal spring 2 includes a straight arm 21, a transition section 22, an oblique arm 23, a support arm 24 and a wiring terminal 27. The transition section 22 is an arc-shaped structure. The straight arm 21 and the oblique arm 23 are respectively integrally formed at the two ends of the transition section 22. The support arm 24 is integrally formed at one end of the oblique arm 23 away from the transition section 22. The wiring terminal 27 is integrally formed at one end of the support arm 24 away from the oblique arm. The end of the straight arm 21 will not move. The transition section 22 and the oblique arm 23 are used to maintain good resilience of the metal spring 2. The support arm 24 is used to maintain good fit between the two metal springs 2 in a free state, increase the fit area, and ensure good conduction performance. The wiring terminal 27 is used to anchor the wire 3 to fix the wire 3.

[0035] Furthermore, the side of the oblique arm 23 is integrally formed with an oblique protrusion 25. A V-shaped groove is formed between the oblique protrusion 25 and the oblique arm 23, and the metal foot of the male plug 200 is inserted into the V-shaped groove, which plays a role in stabilizing the metal foot and enhancing the conductivity between the metal foot of the male plug 200.

[0036] Furthermore, a limiting block 26 is provided on one side of the abutting arm 24 close to the straight arm 21 , and the limiting block 26 is used to prevent the metal spring sheet 2 from being excessively deformed.

[0037] The housing 1 is provided with a spring slot 4 inside, the metal spring 2 is embedded in the inner side of the spring slot 4, the inner side of the spring slot 4 is fixedly connected to a limiting column 41, and the transition section 22 is provided between the spring slot 4 and the limiting column 41. The spring slot 4 is used to install the metal spring 2, which can limit the position of the metal spring 2, and when the oblique arm 23 is squeezed, the straight arm 21 is blocked by the inner wall of the spring slot 4, limiting its movement, and preventing the metal spring 2 from shifting as a whole.

[0038] In this embodiment, a reinforcing mechanism 5 is disposed on the housing 1 between the straight arm 21 and the abutting arm 24 .

[0039] like Figure 4 As shown, the reinforcing mechanism 5 includes a reinforcing wall 51 disposed between the straight arm 21 and the abutting arm 24, the reinforcing wall 51 is integrally formed with the housing 1, and a reinforcing spring piece 52 is disposed between the reinforcing wall 51 and the abutting arm 24, the reinforcing spring piece 52 is a "V"-shaped structure, and the two ends of the reinforcing spring piece 52 are respectively connected to the reinforcing wall 51 and the abutting arm 24. Through the elastic force of the reinforcing spring piece 52, the two abutting arms 24 are pushed to fit each other, thereby enhancing the fitting effect and ensuring conductivity.

[0040] In the present embodiment, a wire fixing mechanism 6 is also included, which includes a threaded column 61 fixedly connected to the inside of the shell 1, and the shell 1 is located on both sides of the threaded column 61 and fixedly connected with threading columns 62, and the bottom of the threading column 62 is provided with a wire passing hole 621, and the wire passing hole 621 is used to pass the wire 3 and then connect with the straight arm 21, the inner side of the threaded column 61 is provided with an internal thread, and the bottom of the threaded column 61 is provided with a reset spring 63, and the upper part of the reset spring 63 is provided with a pressure arm 64, and the two sides of the threaded column 61 are provided with a first adjustment groove allowing the pressure arm 64 to move, and the threading column 62 is provided with a second adjustment groove on one side close to the pressure arm 64, and the two ends of the pressure arm 64 pass through the first adjustment groove and the second adjustment groove and are arranged inside the two threading columns 62, and the top of the threaded column 61 is threadedly connected with a fixing bolt 65, and the two wires 3 pass through the wire passing holes 621 respectively and are connected with the metal spring sheet 2. The two wires 3 are respectively passed through the wire holes 621 on the two threading columns 62, and then connected to the two straight arms 21 by bolts. After the wires 3 pass through the wire holes 621, the fixing bolts 65 are tightened. During the downward movement of the fixing bolts 65, the pressure arm 64 is squeezed to move the pressure arm 64 downward. The two ends of the pressure arm 64 press the wires 3 to prevent them from loosening, thereby fixing the wires 3. When disassembling, by unscrewing the fixing bolts 65, the reset spring 63 pushes the pressure arm 64 to move upward, releasing the pressure on the wires 3, so that the wires 3 can be replaced.

[0041] Furthermore, the wire inlet 11 is provided with a threading rubber ring 111, and the jack 12 is provided with a rubber sleeve 121. The threading rubber ring 111 is used to fix the wire 3, and the rubber sleeve 121 is a wear-resistant rubber sleeve. The rubber sleeve 121 is used to fix the metal sheet of the male plug 200 to improve the stability of the metal sheet after insertion. Both ends of the jack 12 are beveled to facilitate plugging and unplugging.

[0042] Example 2

[0043] like Figure 6 As shown, the difference between this embodiment and embodiment 1 is that the reinforcing mechanism 5 includes a reinforcing wall 51 disposed between the straight arm 21 and the abutting arm 24, a reinforcing spring 53 is disposed between the reinforcing wall 51 and the abutting arm 24, and the two ends of the reinforcing spring 53 are respectively connected to the reinforcing wall 51 and the abutting arm 24. In this embodiment, the elastic force of the reinforcing spring 53 is used to make the two abutting arms 24 fit more closely, the elastic force of the reinforcing spring 53 is stronger, and the fitting effect is better.
