AI Technical Summary
Existing three-prong plugs require rotation when the device is positioned above the socket, which causes the wires to bend and the connection strength to be insufficient, making them difficult to plug in.
The design features a horizontal plug with a first, second, and third socket arranged in a triangular pattern on the housing. The wire mounting groove extends from the side, and the correct and stable insertion direction is ensured through structures such as positioning grooves, anti-foolproof bosses, plug positioning plates, and positioning posts.
The reduced plug rotation angle lowers the difficulty of plugging in and improves the connection strength and stability between the plug and socket.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of plug technology, specifically a horizontal plug. Background Technology
[0002] In existing three-prong plugs, the three prongs are arranged in a triangular pattern in the center of the plug. When plugged into a socket, the plug is generally facing the socket, and the wires extend from the bottom of the plug. Figure 7 As shown, when the device is used above the socket, the plug needs to be rotated at a certain angle to align with the socket. The rotation of the plug will cause the end of the wire to bend. In addition, existing three-prong plugs generally have a reinforced design at the connection between the three-prong plug and the wire to enhance the connection strength between the wire and the plug. This further increases the difficulty of bending the wire and may even apply tension to the plug, making it difficult for the plug and socket to be connected. Therefore, in order to facilitate the connection of the socket and reduce the degree of bending of the wire, this horizontal plug was designed. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figures 1 to 6This utility model provides a technical solution: a horizontal plug, including a housing 1 and a wire mounting groove 2. The wire mounting groove 2 is formed at the lower end of the housing 1 and includes a first slot 21 and a second slot 22. The housing 1 is also formed with a first socket 16, a second socket 17, and a third socket 18. The second socket 17 and the third socket 18 are distributed vertically and are located above the first slot 21. The first socket 16 is located above the second slot 22 and is located in the middle of the second socket 17 and the third socket 18. The first socket 16, the second socket 17, and the third socket 18 are arranged in a triangular pattern. The first socket 16 communicates with the first slot 21. A first plug post 31 is provided in the first socket 16. The first plug post 31 is L-shaped, with one end located at the first slot 21. One end is in the socket 16, and the other end is located in the second slot 22. The second socket 17 and the third socket 18 are both connected to the wire mounting groove 2. The second socket 17 is provided with a second plug post 4, and the third socket 18 is provided with a third plug post 5. The second plug post 4 and the third plug post 5 are both L-shaped, with one end located on the surface extending to the housing 1, and the other end located in the second slot 22. The second plug post 4 and the third plug post 5 are distributed front and back in the second slot 22. All three wires are led out from the bottom of the housing 1. The direction of the wires is perpendicular to the triangular direction of the plug posts, so that when the plug is connected to the socket, the wires are led out from the side of the plug, reducing the rotation angle of the plug and further reducing the difficulty of plug insertion, thus meeting the plug insertion requirements in different directions.
[0023] During the production of this plug, the first pin 31, the second pin 4, and the third pin 5 are all fixed inside the plug as inserts during injection molding.
[0024] like Figure 3 and 4 As shown, a positioning groove 11 is provided inside the housing 1, and a foolproof protrusion 12 is formed on the side of the positioning groove 11. The first insertion hole 16 is provided on the foolproof protrusion 12. The insertion direction of the plug is positioned by the positioning groove 11 and the foolproof protrusion 12 to prevent incorrect insertion.
[0025] like Figure 3 and 5 As shown, the housing 1 also has a recessed hole 14, and a plug-in positioning plate 7 is provided in the recessed hole 14. Plug-in positioning pins 71 are formed on the four corners of the plug-in positioning plate 7. The plug-in positioning pins 71 extend out of the surface of the housing 1. The plug-in positioning plate 7 also serves as an insert during plug injection molding, fixing it inside the plug. The four plug-in positioning pins 71 are used to position the plug during insertion. The ends of the plug-in positioning pins 71 are stepped, further enhancing the rigidity and strength of the plug-in positioning pins 71.
[0026] like Figure 2As shown, a positioning plate fixing hole 13 is provided on the back of the housing 1. A bolt is connected in the positioning plate fixing hole 13. The bolt presses the insertion positioning plate 7 into the housing 1 to prevent the insertion positioning plate 7 from moving.
[0027] The housing 1 also has two positioning holes 15 distributed vertically. The positioning holes 15 are located at the upper and lower ends of the outer side of the second socket 17 and the third socket 18. A positioning post 6 is fixed inside the positioning hole 15. The positioning post 6 is also fixed inside the plug as an insert during the plug injection molding process. The positioning post 6 is used to position the plug during insertion.
[0028] like Figure 3 and 6 As shown, the lower end of the first plug post 31 is connected to a first wire sleeve 3. The first wire sleeve 3 is disposed in the second slot 22. The second slot 22 includes two concentrically distributed rings. The first wire sleeve 3 is disposed in the inner ring and is used to fix the wire.
[0029] The lower ends of the second plug pin 4 and the third plug pin 5 are both connected to the second wire sleeves 8. The two second wire sleeves 8 are located in the first slot 21, which is a waist hole. The two second wire sleeves 8 are used to fix the other two wires. The first wire sleeve 3 and the two second wire sleeves 8 are all inserts, which are fixed in the plug when the plug is formed.
[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
