[0034] The embodiments of this utility model will be further described below with reference to the accompanying drawings:

[0035] like Figures 1-25 As shown, this embodiment provides a three-hole socket module, including a plug socket 1 and a terminal block 2. The plug socket 1 and the terminal block 2 are connected together by a snap-fit ​​mechanism. In addition to snap-fit, the plug socket 1 and the terminal block 2 can also be fixed by bolts or other conventional methods. There are many conventional fixing methods on the market. The bottom of the terminal block 2 is provided with multiple sets of terminals 21. Each terminal 21 is provided with a terminal hole 211 for inserting a wire 6. The inner side of the terminal 21 is provided with a self-locking spring plate seat 212. A self-locking spring plate 3 is installed in the self-locking spring plate seat 212. The end of the self-locking spring plate 3 near the terminal hole 211 is bent to form an elastic inclined surface 31. The other end of the self-locking spring plate 3 is bent into an S-shaped elastic contact end 32. The bending direction of the self-locking spring plate 3 is consistent with the direction in which the wire 6 is inserted into the terminal hole 211. The elastic inclined surface 31, under its own elasticity, locks the wire 6 to prevent the wire 6 from being pulled. The wiring hole 211 can be designed with a larger outer diameter and a smaller inner diameter to allow for quick insertion of the wire 6.

[0036] A copper component 4 is installed above the self-locking spring holder 212. One end of the copper component 4 is provided with a plug contact end 44, and the other end of the copper component 4 is provided with a wire contact surface 45. A self-locking spring limiting surface 46 is provided in the middle of the copper component 4. The self-locking spring limiting surface 46 restricts the movement of the self-locking spring 3 within the self-locking spring holder 212.

[0037] When the elastic inclined surface 31 locks the wire 6, the wire 6 comes into contact with the wire contact surface 45. The self-locking spring 3 is made of a conductive and elastic material.

[0038] The plug socket 1 has a plastic pressure plate 5 installed above the copper part 4. The plastic pressure plate 5 has a first socket hole 51, and the plug socket 1 has a second socket hole 11 at the corresponding position of the first socket hole 51.

[0039] In use, insert the wire 6 into the wiring hole 211. The wire 6 passes through the self-locking spring 3 and contacts the elastic bevel 31 of the wiring hole 211. The elastic bevel 31 then bends, allowing the wire 6 to continue to be inserted until it is fully inserted and contacts the elastic contact end 32. If the user pulls the wire 6 outward at this point, the elastic bevel 31 will firmly lock the wire 6 in place, thus allowing the wire 6 to be quickly connected without falling off on its own, avoiding the need for screws or other fixing methods.

[0040] In the field of wall switches, it is common for a single wire to connect to multiple wall switches simultaneously. To address this issue, preferably, each set of terminals 21 has two wiring holes 211. A push wire 7 is installed in the middle of the self-locking spring holder 212, and self-locking springs 3 are installed on both sides of the push wire 7. This allows two wires 6 to be connected to the two wiring holes 211, achieving one inlet and one outlet, with the outlet wire leading to other locations.

[0041] To facilitate the installation and fixing of the self-locking spring 3, preferably, each set of terminals 21 is provided with a positioning groove 213 between the two wiring holes 211, and the pusher 7 is provided with a positioning boss 71 near the positioning groove 213. The positioning boss 71 matches the positioning groove 213, and the pusher 7 separates the two self-locking springs 3 in the self-locking spring holder 212 on both sides.

[0042] Preferably, the pusher 7 has self-locking spring limiting bosses 72 on both sides, which restrict the movement of the elastic inclined surface 31 of the self-locking spring 3 towards the wiring hole 211. This prevents the elastic inclined surface 31 of the self-locking spring 3 from overshooting when no wire 6 is inserted.

[0043] In addition, since the self-locking spring limiting boss 72 of the pusher 7 rests on the elastic inclined surface 31 when the wire 6 is not inserted, the elastic inclined surface 31 will move away from the self-locking spring limiting boss 72 when the wire 6 is inserted. If it is necessary to quickly remove the wire, simply push the positioning boss 71 inward through the positioning groove 213 so that the self-locking spring limiting boss 72 contacts the elastic inclined surface 31, and finally make the elastic inclined surface 31 leave the wire 6. At this time, the wire 6 can be easily pulled out.

[0044] To facilitate the linear movement of the pusher 7, preferably, the wire contact surface 45 of the copper part 4 is provided with a notch 47 in the middle, and the notch 47 matches the pusher 7, so that the pusher 7 will not run around when the positioning boss 71 is pressed inward.

[0045] Since plugs generally have two or three holes, preferably, the number of the second socket hole 11, the terminal 21, the copper piece 4, and the first socket hole 51 are all two. The two copper pieces 4 are a first copper piece 41 and a second copper piece 42. Both the first copper piece 41 and the second copper piece 42 are provided with a plug contact end 44, a wire contact surface 45, and a self-locking spring limiting surface 46. The structures of the first copper piece 41 and the second copper piece 42 are symmetrical. The two second socket holes 11 form a two-hole socket. This makes it suitable for two-hole plugs.

[0046] Preferably, there are three second socket holes 11, three terminals 21, three copper parts 4, and three first socket holes 51. The three copper parts 4 are a first copper part 41, a second copper part 42, and a ground copper part 43. Each of the first copper part 41, the second copper part 42, and the ground copper part 43 is provided with a plug contact end 44, a wire contact surface 45, and a self-locking spring limiting surface 46. The structure of the first copper part 41 is symmetrical to that of the second copper part 42. The three second socket holes 11 form a three-hole socket. The addition of the ground copper part 43 is used for grounding, thereby enabling the connection of a three-prong plug.

[0047] To improve the safety of wall switches and prevent children from accidentally inserting metal parts, preferably, the plastic pressure plate 5 has a safety door stop 52 at the middle position of its side. Safety doors 8 are installed on both the left and right sides of the plastic pressure plate 5. Spring-loaded fixing protrusions 81 are installed on both sides of each safety door 8. Spring mounting seats 53 are provided at corresponding positions of the two spring-loaded fixing protrusions 81 on the plastic pressure plate 5. A spring 9 is installed between the spring mounting seats 53 and the spring-loaded fixing protrusions 81. When the safety door 8 is pressed against the safety door stop 52 by the spring 9, the safety door 8 is positioned above the two first socket holes 51. The safety door 8 can only be opened when both protrusions of the plug are inserted simultaneously; insertion from only one side is not possible, effectively improving safety.

[0048] To ensure that the safety door 8 can only move in a straight line, preferably, the safety door 8 is equipped with a guide rail 82, and the plastic pressure plate 5 is provided with a guide rail groove 54. The guide rail 82 and the guide rail groove 54 cooperate with each other to make the safety door 8 move in a straight line on the guide rail groove 54.

[0049] This embodiment should not be regarded as a limitation of the utility model, but any improvement made based on the spirit of the utility model should be within the protection scope of the utility model.
