[0030] In order to solve the problem of low applicability of sockets in the prior art, the utility model provides a plug and a socket, wherein the socket includes the plug.

[0031] like Figures 1 to 6 As shown, the plug includes an injection molded part 10 and a plug assembly. The plug assembly includes a plug 20 and a connecting piece 30. The connecting piece 30 has a convex structure and / or a concave structure along the extension direction. The injection molded part 10 adaptively covers at least a portion of the fixed plug 20 and at least a portion of the connecting piece 30. In other words, the connecting piece 30 has at least one upward or downward step. There are multiple plug assemblies, and the multiple plug assemblies include an L-pole plug assembly, an N-pole plug assembly, and an E-pole plug assembly. The connecting pieces 30 of the L-pole plug assembly, the N-pole plug assembly, and the E-pole plug assembly extend to the same side or opposite sides of the plug.

[0032] The plug includes an injection molded part 10 and a plug assembly, the plug assembly includes a plug 20 and a connecting piece 30, the connecting piece 30 has a convex structure and / or a concave structure along the extension direction, and the injection molded part 10 adaptively covers at least a portion of the fixed plug 20 and at least a portion of the connecting piece 30, so that by setting the connecting piece 30 to have a convex and concave structure, the connecting piece 30 is in an uneven step shape, and the step bending part of the connecting piece 30 after injection molding is in a hook-shaped structure, thereby forming a limit stop with the injection molded part 10, thereby improving the overall structural strength of the plug and making the internal structure of the plug firmly connected; further, the plug assembly is multiple, and the multiple plug assemblies It includes an L-pole plug assembly, an N-pole plug assembly and an E-pole plug assembly. The connecting pieces 30 of the L-pole plug assembly, the N-pole plug assembly and the E-pole plug assembly extend to the same side or opposite sides of the plug, so that the connecting piece 30 can pass through the entire injection molded part 10, further improving the connection stability between the injection molded part 10 and the plug assembly, and by reasonably adjusting the arrangement of the connecting piece 30, there will be no obstruction to the plug, so that the plug can move along the socket body, and then the socket can adaptively adjust its position according to the actual usage scenario to avoid other objects or get closer to electrical equipment, which greatly improves the applicability of the socket and thus improves the user experience.

[0033] Specifically, one end of the plug 20 is connected to one end of the connecting piece 30, and the plug 20 and the connecting piece 30 are perpendicular or approximately perpendicular to each other as a whole. The injection molded part 10 covers the connecting portion of the plug 20 and the connecting piece 30. The other end of the plug 20 is a plug-in end, and a plug hole is provided on the front side of the injection molded part 10. The plug-in end extends out of the injection molded part 10 from the plug hole to be plugged into the power socket. The other end of the connecting piece 30 is a protruding end, which is used to be welded to the wire or conductive sheet inside the socket, so as to supply power to the socket structure. Specifically, the welding method can be resistance welding, and the connection reliability is high.

[0034] In the present embodiment, the plug is a three-plug plug, so there are multiple plug assemblies, and the multiple plug assemblies include an L-pole plug assembly, an N-pole plug assembly, and an E-pole plug assembly. In the present embodiment, the connecting pieces 30 of the L-pole plug assembly, the N-pole plug assembly, and the E-pole plug assembly extend to the same side of the plug, and at least a portion of the projections of the three connecting pieces 30 along the arrangement direction overlap. In other words, the extending ends of the connecting pieces 30 of the multiple plug assemblies are oriented in the same direction. Specifically, the three connecting pieces 30 are spaced apart along a first direction, and the connecting pieces 30 extend along a second direction, wherein the first direction is perpendicular to the second direction. It can be understood that the first direction is Figure 1 The left and right direction in the image is the first direction, and the second direction is the up and down direction. Figure 3As shown, the extended ends of the connecting pieces 30 of the three-phase plug assembly in this embodiment are all facing the same direction, and the three connecting pieces 30 are parallel to each other. Of course, in an optional embodiment, the connecting pieces 30 of the three plug assemblies can be extended to the opposite sides of the plug respectively, for example, the connecting pieces 30 of the L-pole plug assembly and the N-pole plug assembly extend to the first side of the plug, and the connecting piece 30 of the E-pole plug assembly extends to the second side of the plug, which can be selected according to actual needs. It can be understood that when the connecting pieces 30 of the three plug assemblies extend to the opposite sides of the plug, the above-mentioned opposite sides refer to the opposite sides along the moving direction of the plug, so as to avoid blocking the plug.

[0035] Furthermore, due to the different positions of the three latches 20, the lengths of the three connecting pieces 30 are not completely the same. Figure 3 As shown, the connecting pieces 30 of the L-pole plug assembly and the N-pole plug assembly are symmetrically arranged, and the multiple steps of the above two connecting pieces 30 are first upward and then gradually downward; the length of the connecting piece 30 of the E-pole plug assembly is less than the length of the above two connecting pieces 30, and the multiple steps of the connecting piece 30 of the E-pole plug assembly are gradually downward. Furthermore, the protruding ends of the three connecting pieces 30 are flush. In this embodiment, the projections of the connecting pieces 30 of the three plug assemblies along the first direction within the length range of the connecting piece 30 of the E-pole plug assembly coincide, that is, the shapes remain consistent. Furthermore, the projections of the connecting pieces 30 of the L-pole plug assembly and the N-pole plug assembly outside the length range of the connecting piece 30 of the E-pole plug assembly also coincide along the first direction.

[0036] In this embodiment, the thickness of the injection molded part 10 covering the plug 20 and the front and rear sides of the connecting piece 30 is the same. With the above arrangement, the step structure adapted to the connecting piece 30 forms a flat surface on the front side of the plug and a groove on the rear side, such as Figure 1 to Figure 2 Through the above arrangement, the injection molded wall thickness of the injection molded part 10 on the front and rear sides of the latch 20 and the connecting piece 30 is relatively uniform, thus avoiding the occurrence of adverse problems such as injection shrinkage.

[0037] In this embodiment, the latch 20 is detachably connected to the connecting piece 30. Figures 4 to 6 As shown, a mounting post 21 is provided at the bottom end of the latch 20, and a mounting hole (not shown) is correspondingly opened at one end of the connecting piece 30, and the mounting post 21 is plugged into and matched with the mounting hole.

[0038] like Figures 4 to 6As shown, two limiting protrusions 22 are respectively provided on both sides of the plug 20, and the two limiting protrusions 22 protrude from the plug 20 along the width direction of the plug 20, and are used to limit and stop with the injection molded part 10. It can be understood that the width direction of the plug 20 is perpendicular to the extension direction of the plug 20. Further, the two limiting protrusions 22 are arranged symmetrically on the left and right. After the injection molding is completed, the limiting protrusions 22 form a barb structure, which limits and stops with the injection molded part 10, thereby improving the connection firmness between the plug 20 and the injection molded part 10 and enhancing the overall structural strength of the plug.

[0039] like Figure 1 to Figure 2 ,as well as Figure 6 As shown, in this embodiment, a partition 11 is provided on one side of the injection molded part 10 corresponding to the protruding end of the connecting piece 30. There are multiple partitions 11, and a receiving groove 12 is formed between two adjacent partitions 11. The protruding end of the connecting piece 30 is located in the receiving groove 12. Specifically, the protruding end of the connecting piece 30 extends upward and extends out of the injection molded part 10 into the receiving groove 12. Therefore, the partition 11 is provided on the upper side of the injection molded part 10. The two adjacent partitions 11 and the upper side of the injection molded part 10 form a U-shaped receiving groove 12, which encloses the protruding end of the connecting piece 30. Furthermore, the protruding end of the connecting piece 30 is the part of the last step, and the last step is fitted with the upper side of the injection molded part 10 to form a limit stop, thereby improving the connection firmness. Specifically, there are four partitions 11, which are arranged at equal intervals along the first direction, and two partitions 11 are respectively located at the two ends of the upper side of the injection molded part 10, thereby forming three accommodating grooves 12, which respectively accommodate the protruding ends of the three connecting pieces 30. Through the above arrangement, the distance between the polar components is increased, so that the polar components are insulated and isolated, ensuring electrical safety. Of course, when the connecting pieces 30 of the three plug assemblies extend to the opposite sides of the plug, the partitions 11 are arranged on the opposite sides of the injection molded part 10 corresponding to the protruding ends of the connecting pieces 30.

[0040] like Figure 1 to Figure 2 ,as well as Figure 6As shown, in this embodiment, a beam 13 is provided on one side of the injection molded part 10 corresponding to the extended end of the connecting piece 30, and the beams 13 are arranged in groups of two. The two beams 13 in one group protrude from the front and rear side surfaces of the injection molded part 10 in opposite directions, and the projection of the connecting piece 30 in a direction parallel to the injection molded part 10 is located in the beam 13. Specifically, the beam 13 is located on the upper side of the injection molded part 10 and extends in a first direction, and the projection of the connecting piece 30 in a second direction is located in the beam 13. Through the above arrangement, the distance between the polar component and the external touchable position is increased to ensure electrical safety. Further, the partition 11 is connected to the beam 13 and is flush with the beam 13 in the thickness direction of the injection molded part 10, further ensuring that there is a sufficient distance between the polar component and the external touchable position. Of course, when the connecting pieces 30 of the three plug assemblies extend to the opposite sides of the plug, the beams 13 are in two groups, and the two beams 13 are respectively arranged on the opposite sides of the extended end of the injection molded part 10 corresponding to the connecting piece 30.

[0041] like Figure 2 and Figure 6 As shown, a development process hole 14 is provided on the rear side of the injection molded part 10, and the development process hole 14 is provided corresponding to the latch assembly. Specifically, in this embodiment, there are three development process holes 14, and the three development process holes 14 are respectively provided at three latch assemblies. Through the above arrangement, during the injection molding process, a tool can be used to pass through the development process hole 14 to support the latch assembly, thereby preventing the latch assembly from being displaced and deformed during the injection molding process.

[0042] like Figure 1 to Figure 2 As shown, the plug further includes a first fixing member 40. The first fixing member 40 is located on one of the left and right sides of the injection molded part 10, and is used to pre-fix with the socket along a first direction. Specifically, in this embodiment, the first fixing member 40 is a tongue piece, and when the plug and the socket are assembled, the tongue piece can pre-fix the plug to prevent factors such as welding from causing the plug to move and affect assembly.

[0043] like Figure 1 to Figure 2 ,as well as Figure 6 As shown, the plug further includes a second fixing member 50. The second fixing member 50 is located on one side of the upper and lower sides of the injection molded part 10 away from the extended end of the connecting piece 30, and is at least used for pre-fixing with the socket along the second direction. There are multiple second fixing members 50, and the multiple fixing members are arranged at intervals along the first direction. Specifically, in this embodiment, the second fixing member 50 is located on the lower side of the injection molded part 10, and the second fixing member 50 is a boss protruding downward from the injection molded part, and there are two bosses, which are respectively located at the two ends of the lower side of the injection molded part 10.

[0044] like Figure 1As shown, the second fixing member 50 has an assembly surface 51 and a fixing surface 52 connected in sequence along the second direction, and the fixing surface 52 is away from the injection molded part 10 relative to the assembly surface 51, and is used for pre-fixing with the socket. The assembly surface 51 is higher than the fixing surface 52 to form a step surface structure for assembly with the socket.

[0045] like Figure 7 As shown, the present application also provides a socket, including a socket body 100 and the above-mentioned plug 200 , and the plug 200 is movably disposed on the socket body 100 .

[0046] In this embodiment, the socket is a converter socket, and the plug is directly set in the socket without the need for a power extension cord. The socket body 100 is provided with an avoidance opening 110, and the plug pin 20 of the plug extends out of the socket body 100 from the avoidance opening 110, thereby plugging into the power socket. Specifically, the plug 200 moves relative to the socket body 100 along a first direction, that is, the position of the socket body 100 is adjustable relative to the plug 200 and the power socket, so that the position of the socket body 100 can be adaptively adjusted according to the actual usage scenario to avoid other objects or get closer to electrical equipment, which greatly improves the applicability of the socket and provides a better user experience. Of course, the moving direction of the plug 200 can also be other directions such as the second direction, which can be selected according to actual needs.

[0047] In this embodiment, by arranging the extended ends of the three connecting pieces 30 on the same side of the injection molded part 10, wiring is convenient and the plug 200 can be moved while powered.

[0048] In this embodiment, since the plug 200 needs to be movable, the material of the injection molded part 10 can be selected from wear-resistant materials such as nylon or other alloy materials, and at the same time needs to meet other requirements such as flame retardancy and electrical properties.

[0049] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by setting the plug to include an injection molded part 10 and a plug assembly, the plug assembly includes a plug 20 and a connecting piece 30, and the connecting piece 30 has a convex structure and / or a concave structure along the extension direction, and the injection molded part 10 adaptively covers at least a portion of the fixed plug 20 and at least a portion of the connecting piece 30, so that by setting the connecting piece 30 to have a convex and concave structure, the connecting piece is in an uneven step shape, and the step bending part of the connecting piece 30 after injection molding is in a hook-shaped structure, thereby forming a limit stop with the injection molded part 10, thereby improving the overall structural strength of the plug, and making the internal structure of the plug firmly connected; further There are multiple plug assemblies, including an L-pole plug assembly, an N-pole plug assembly and an E-pole plug assembly. The connecting pieces 30 of the L-pole plug assembly, the N-pole plug assembly and the E-pole plug assembly extend to the same side or opposite sides of the plug, so that the connecting piece 30 can pass through the entire injection molded part 10, further improving the connection stability between the injection molded part 10 and the plug assembly, and by reasonably adjusting the arrangement of the connecting piece 30, there will be no obstruction to the plug, so that the plug can move along the socket body, and then the socket can adaptively adjust its position according to the actual usage scenario to avoid other objects or get closer to electrical equipment, which greatly improves the applicability of the socket and thus improves the user experience.
