[0002] Among various commonly used AC power plugs and sockets, the zigzag plug and socket are widely used in various electrical appliances at home and abroad due to their advantages such as convenient connection and good reliability. The zigzag plug is divided into two types according to the placement direction of its blades: horizontal zigzag plug and vertical zigzag plug. The existing zigzag socket is not universal, and different types of sockets need to be set to adapt to different types of plugs; Figure 1 As shown, it is a horizontal contact socket that is compatible with the horizontal herringbone plug. Figure 2 The figure shows a vertical contact socket compatible with a vertical herringbone plug. As can be seen, existing AC power sockets lack versatility, resulting in a poor user experience. Furthermore, different socket types require the development of different molds, increasing costs.

DETAILED DESCRIPTION

[0033] In order to facilitate understanding by those skilled in the art, the present invention is further described below with reference to embodiments and drawings. The contents mentioned in the embodiments are not intended to limit the present invention.

[0034] Example 1

[0035] As Figures 3 to 12 shown, a multi-purpose AC power socket provided by the utility model includes a housing 1 and a terminal assembly. The housing 1 includes a plug-in block 11, and three plug-in through holes 12 are provided on the plug-in block 11. One end of each plug-in through hole 12 is a through-hole plug-in end 121, and the through-hole plug-in end is provided in a "T" shape; the terminal assembly includes three metal terminals 2, and one of the metal terminals 2 is arranged in each plug-in through hole 12. One end of the metal terminal 2 corresponding to the through-hole plug-in end 121 is a terminal plug-in end, and a "T"-shaped plug-in gap 21 is formed in the terminal plug-in end. Specifically, the housing 1 is integrally injection-molded from plastic, with simple molding steps and low cost; the three plug-in through holes 12 are arranged in a "pin" shape on the plug-in block 11, and the through-hole plug-in end 121 of the plug-in through hole 12 is provided in a "T" shape. Of course, the entire plug-in through hole 12 can also be set in a "T" shape, and the specific shape is adaptively designed according to the structure of the metal terminal 2 in practice; the vertical segments in the "T" shapes of the three through-hole plug-in ends are arranged close to each other. The "T"-shaped plug-in gap 21 in the metal terminal 2 is correspondingly arranged with the "T"-shaped through-hole plug-in end 121, facilitating the insertion of the plug blades through the "T"-shaped through-hole plug-in end 121 into the corresponding "T"-shaped plug-in gap 21, and then the plug-in gap 21 clamps the plug blades to achieve the plugging of the plug. The three metal terminals 2 are respectively a ground wire terminal, a neutral wire terminal and a live wire terminal.

[0036] In this embodiment, by setting the corresponding "T"-shaped through-hole plug-in end 121 and "T"-shaped plug-in gap 21, since both the through-hole plug-in end 121 and the plug-in gap 21 have a horizontal plug-in space and a vertical plug-in space, therefore, both the horizontal "pin" - shaped plug blades and the vertical "pin" - shaped plug blades can be accommodated in the "T"-shaped through-hole plug-in end 121 and the "T"-shaped plug-in gap 21, with strong versatility; and the user only needs to prepare one form of AC power socket to adapt to two different forms of "pin" - shaped plugs, and there is no need to find the corresponding AC power socket according to the specific form of the "pin" - shaped plug during use, which is simple and fast, and the use experience is good; and the manufacturer also does not need to develop different molds for different forms of AC power sockets, saving costs.

[0037] Embodiment 2

[0038] See appendix Figure 3-12 , based on Embodiment 1, this embodiment further defines that at least one limiting block 13 is provided on the outer side of the plug-in block 11.

[0039] In this embodiment, by providing a limit block 13, the movement space of the T-shaped plug after being inserted into the AC power socket is prevented from being too large, which may cause the T-shaped plug and the AC power socket to be misaligned or unstable, thereby ensuring the plugging stability and plugging reliability of the T-shaped plug and the AC power socket.

[0040] Furthermore, a contact plane 131 is provided on one side of the limit block 13 close to the plug block 11. In this embodiment, by providing the contact plane 131 on one side of the limit block 13, the contact area between the limit block 13 and the herringbone plug is increased, thereby providing a better limiting effect on the herringbone plug.

[0041] Furthermore, there are two limit blocks 13, and the two limit blocks 13 are symmetrically arranged outside the plug block 11. In this embodiment, by symmetrically arranging two limit blocks 13 outside the plug block 11, the position of the herringbone plug can be restricted from both sides, which is more effective.

[0042] Furthermore, the housing 1 further includes an outer frame 14, a receiving groove 15 being formed in the middle of the outer frame 14, and the plug-in block 11 and the limit block 13 are disposed in the receiving groove 15. In this embodiment, by disposing the plug-in block 11 and the limit block 13 in the receiving groove 15, the plug-in block 11 and the limit block 13 can be protected by the side walls of the outer frame 14, thereby preventing them from being easily damaged by the external environment.

[0043] Furthermore, the upper ends of two opposite side walls of the outer frame 14 are each provided with a protrusion 16 , and a locking hole 161 is defined in the protrusion 16 .

[0044] Furthermore, a positioning groove 17 is provided on one side wall of the plug block 11. In this embodiment, by providing the positioning groove 17 on the plug block 11 and correspondingly providing a positioning protrusion on one side wall of the herringbone plug, the positioning groove 17 cooperates with the positioning protrusion during plugging, thereby ensuring that the herringbone plug and the AC power outlet can be quickly aligned during plugging, facilitating user operation.

[0045] Example 3

[0046] See attached Figure 3-12Based on Example 1, this embodiment further defines that: the metal terminal 2 includes a conductive sheet 22, one end of which is connected to a first spring sheet 23. One surface of the first spring sheet 23 is a plugging surface 231. Two second spring sheets 24 are disposed outside the plugging surface 231. The two second spring sheets 24 are respectively connected to the first spring sheet 23 via a connecting arm 25. Specifically, the conductive sheet 22 is located at the end of the plugging hole 12 that is opposite to the plugging end 121 of the through-hole. The conductive sheet 22 is used to connect to an external power source to energize the first spring sheet 23 and the second spring sheet 24. When the plug of the herringbone plug is inserted into the plugging gap 21, the first spring sheet 23, the second spring sheet 24 and the plug can smoothly conduct electricity, thereby connecting the power supply to the electrical appliance.

[0047] Furthermore, the insertion gap 21 includes a first gap 211 and a second gap 212 , and the first gap 211 and the second gap 212 are arranged perpendicular to each other.

[0048] Furthermore, the plugging surface 231 of the first elastic piece 23 is arranged opposite to the side walls of the two second elastic pieces 24, and the first gap 211 is formed between the plugging surface 231 and the two side walls; the two second elastic pieces 24 are arranged opposite to each other, and the second gap 212 is formed between the two second elastic pieces 24.

[0049] In this embodiment, the metal terminal 2 can be obtained by stamping, and by reasonably arranging the relative positions between the first spring piece 23 and the two second spring pieces 24, specifically, the two second spring pieces 24 are located on the outside of the plug-in surface 231 of the first spring piece 23 and the two second spring pieces 24 are arranged perpendicular to the first spring piece 23, so that a first gap 211 and a second gap 212 perpendicular to each other can be formed between the three, which has a simple structure, low material consumption and low cost.

While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
