Description

Technical Field

[0001] This utility model relates to the field of electrical safety protection devices, and in particular to a circular charging socket anti-electric shock protection device. Background Technology

[0002] In existing electrical equipment, single-phase AC charging sockets are widely used in electric vehicles, industrial equipment, and home charging facilities. When not in use, the internal metal sockets of these sockets are exposed, posing a high risk of electric shock, especially in humid, dusty, or child-friendly environments. Accidental contact, insertion of foreign objects, or moisture intrusion can easily lead to short circuits, leakage, or even personal injury.

[0003] Currently, some charging sockets use fixed covers or manually flip-top covers for protection. However, fixed covers cannot open automatically, affecting ease of use. Ordinary flip-top covers only provide surface protection and lack internal interlocking protection, allowing small metal objects or fingers to still be inserted, resulting in a low level of protection. Furthermore, existing structures generally suffer from poor sealing, easy dust and water accumulation, and unreliable mechanical linkages. After prolonged use, they are prone to jamming, poor reset, and other malfunctions, failing to meet high standards of electrical safety requirements.

[0004] Therefore, it is necessary to design a circular charging socket electric shock protection device to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of existing charging socket protection structures, such as low protection level, lack of automatic linkage protection mechanism, susceptibility to foreign object insertion, and poor sealing performance, this utility model provides a circular charging socket anti-electric shock protection device.

[0006] The technical solution is as follows: A circular charging socket anti-electric shock protection device includes a flip cover, foam, end cover, torsion spring, pin, silicone pad, gasket, screw, upper cover, protective component, lower cover, nut, O-ring 1, O-ring 2, single-phase socket housing, and rear cover. The upper front part of the end cover is rotatably connected to the flip cover via a pin. A torsion spring is sleeved on the outer circumference of the pin. Foam is provided between the end cover and the flip cover, and the foam is embedded in the front side of the end cover. The upper cover is installed on the rear side of the end cover. A silicone pad and gasket are provided between the upper cover and the end cover. The lower cover is connected to the rear side of the upper cover via a screw. The screw passes through the end of the lower cover and engages with the nut threadedly, realizing the connection between the upper cover and the lower cover. The cover is detachably connected. The front of the lower cover has a protective component, which includes an upper protective mechanism, a side protective mechanism, and a lower protective mechanism. The rear of the lower cover is connected to the single-phase socket housing by screws. The upper front of the single-phase socket housing has two 3mm holes, and an O-ring seal is provided around each 3mm hole. The lower front has multiple 6mm holes, and an O-ring seal is provided around each 6mm hole. The rear of the single-phase socket housing is connected to the rear cover by screws. The foam, end cap, silicone pad, gasket, upper cover, and lower cover all have through grooves in the middle. The through grooves are adapted to the shape of the charging socket. When the cover is closed, it covers the through grooves to form a shielding fit.

[0007] Preferably, the upper protection mechanism includes an upper push baffle and a return torsion spring. The upper push baffle is slidably connected to the upper front side of the lower cover. The upper part of the upper push baffle is connected to the lower cover. The lower front part of the upper push baffle protrudes from the upper part of the through groove and is provided with a guide slope.

[0008] Preferably, the side protection mechanism includes a left baffle, a right baffle, and a tension spring. The left and right baffles are rotatably connected to the left and right sides of the front of the lower cover, respectively. A tension spring is connected between the upper outer sides of the left and right baffles and the two ends of the upper push baffle.

[0009] Preferably, the lower protection mechanism includes a lower push baffle one, a lower push baffle two, and a torsion spring. The lower left and right sides of the lower front side of the lower cover are rotatably connected by a pivot to the lower push baffle one and the lower push baffle two, which are arranged opposite to each other. A torsion spring is provided between the lower push baffle one and the lower push baffle two.

[0010] Preferably, the left and right baffles are symmetrically arranged, with an extension on the side closest to each other. The extension forms a shielding fit with the outer area of ​​multiple 6mm sockets, and a hook block is provided at the lower end of the left and right baffles.

[0011] Preferably, the upper front sides of the first and second lower push baffles protrude from the upper area of ​​the through groove and are provided with guide slopes. The ends of the first and second lower push baffles that are far apart from each other are provided with hook blocks, which are adapted to the corresponding hook blocks.

[0012] The beneficial effects of this utility model are as follows: 1. This utility model sets up a multi-level protection mechanism consisting of an upper push baffle, a left baffle, a right baffle, a lower push baffle one, and a lower push baffle two, and combines it with the linkage opening mechanism of the flip cover. When the plug is not inserted, each baffle works together to cover the 3mm and 6mm socket areas. Only when a standard plug is inserted is the guide inclined surface pushed to achieve step-by-step opening, which achieves the effect of preventing fingers or foreign objects from accidentally touching the live socket and effectively improving the safety of electricity use.

[0013] 2. This utility model forms a multi-point elastic reset structure by setting a return torsion spring between the upper push plate and the lower cover, a tension spring between the left and right baffles, and a torsion spring between the first and second lower push plates. This, together with the torsion spring of the flip cover, enables the automatic reset of the entire mechanism, achieving the effect of reliable closure of each protective component after the plug is unplugged and high stability during long-term use.

[0014] 3. This utility model improves the overall dustproof and waterproof performance of the device by setting O-ring one and O-ring two around the 3mm and 6mm sockets respectively, and combining them with sealing elements such as foam and silicone gaskets. At the same time, it adopts a modular split structure, and the upper cover, lower cover, single-phase socket housing and rear cover can be detachably connected by screws and nuts, which improves the protection level and facilitates assembly and maintenance.

The upper front part of the end cover 3 is rotatably connected to the flip cover 1 via the pin 5. The torsion spring 4 is sleeved on the outer circumference of the pin 5. Foam 2 is provided between the end cover 3 and the flip cover 1, and the foam 2 is embedded in the front side of the end cover 3. The upper cover 9 is installed on the rear side of the end cover 3. A silicone pad 6 and a gasket 7 are provided between the upper cover 9 and the end cover 3. The lower cover 18 is connected to the rear side of the upper cover 9 via a screw 8. The screw 8 passes through the end of the lower cover 18 and is threaded into the nut 19, realizing the connection between the upper cover 9 and the lower cover 18. The lower cover 18 is disassembled and connected. A protective component is provided on the front side of the lower cover 18. The protective component includes an upper protective mechanism, a side protective mechanism, and a lower protective mechanism. The rear side of the lower cover 18 is connected to the single-phase socket housing 24 by screws 8. Two 3mm socket holes 20 are opened on the upper front side of the single-phase socket housing 24. O-rings 21 are provided around the 3mm socket holes 20. Multiple 6mm socket holes 22 are opened on the lower front side. O-rings 23 are provided around the 6mm socket holes 22. The rear cover 25 is connected to the rear side of the single-phase socket housing 24 by screws 8. Through grooves are opened in the middle of the foam 2, end cap 3, silicone pad 6, gasket 7, upper cover 9, and lower cover 18. The through grooves are adapted to the shape of the charging socket. When the flip cover 1 is closed, it covers the through grooves to form a shielding fit.

[0024] like Figure 3 , Figure 4 and Figure 6 As shown, the upper protection mechanism includes an upper push baffle 16 and a return torsion spring 12. The upper push baffle 16 is slidably connected to the upper front part of the lower cover 18. The return torsion spring 12 is connected between the upper part of the upper push baffle 16 and the lower cover 18. The lower front part of the upper push baffle 16 protrudes from the upper part of the through groove and is provided with a guide slope.

[0025] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the side protection mechanism includes a left baffle 10, a right baffle 13, and a tension spring 11. The left baffle 10 and the right baffle 13 are rotatably connected to the left and right sides of the front part of the lower cover 18, respectively. A tension spring 11 is connected between the upper outer side of the left baffle 10 and the two ends of the upper push baffle 16. The left baffle 10 and the right baffle 13 have a left-right symmetrical structure. An extension is provided on the side that is close to each other. The extension forms a shielding fit with the outer area of ​​multiple 6mm insertion holes 22. A hook is provided at the lower end of the left baffle 10 and the right baffle 13.

[0026] like Figure 3 , Figure 4 and Figure 6 As shown, the lower protection mechanism includes a lower push baffle 14, a lower push baffle 2 17, and a torsion spring 15. The lower left and right sides of the front lower part of the lower cover 18 are rotatably connected by a pivot to the lower push baffle 14 and the lower push baffle 2 17, which are arranged opposite each other. A torsion spring 15 is provided between the lower push baffle 14 and the lower push baffle 2 17. The upper front part of the lower push baffle 14 and the lower push baffle 2 17 protrudes into the upper area of ​​the through groove and is provided with a guide slope 2. A hook block 2 is provided at the opposite ends of the lower push baffle 14 and the lower push baffle 2 17, and the hook block 2 is adapted to the corresponding hook block 1.

[0027] When the charging socket is not in use, the flip cover 1 remains closed under the action of the torsion spring 4, and the foam 2 provides cushioning and sealing. At the same time, the upper push baffle 16 is in the initial position under the action of the return torsion spring 12. The left baffle 10 and the right baffle 13 are driven to retract inward by the tension springs 11 on both sides, so that the extension covers the outer area of ​​multiple 6mm sockets 22. The lower push baffle 14 and the lower push baffle 27 remain closed under the action of the torsion spring 15, together covering the lower area of ​​the through slot, realizing multiple physical protection for the 3mm socket 20 and the 6mm socket 22, preventing foreign objects from being inserted or the human body from contacting the live parts.

[0028] When a standard charging plug is inserted, the front end of the plug first pushes the flip cover 1 to rotate around the pin 5 and open it. Then, it continues to push the flip cover 1 to contact the guide slope 1 on the front side of the upper push plate 16, pushing the upper push plate 16 to slide up along the lower cover 18. During the upward movement of the upper push plate 16, the tension spring 11 is compressed, causing the left baffle 10 and the right baffle 13 to rotate outward around their respective axes, so that the extension part is separated from the 6mm socket 22 area. At the same time, the plug pushes the guide slope 2 on the front side of the lower push plate 14 and the lower push plate 27 to overcome the elastic force of the torsion spring 15, so that the two baffles open around the axis. During this process, the hook block 1 at the lower end of the left baffle 10 and the right baffle 13 slides and engages with the hook block 2 of the lower push plate 14 and the lower push plate 27 to ensure smooth linkage. Finally, the through slot is fully opened, and the plug is smoothly inserted into the corresponding 3mm socket 20 or 6mm socket 22 to complete the electrical connection.

[0029] After the plug is unplugged, the torsion spring 4 drives the flip cover 1 to reset and close, the return torsion spring 12 resets the upper push plate 16, the tension spring 11 contracts and drives the left baffle 10 and the right baffle 13 to rotate to the shielded position, and the torsion spring 15 pushes the lower push plate 14 and the lower push plate 2 17 to close, restoring the full protection of the plug hole.

[0030] This device achieves a safety protection function by automatically opening when the plug is inserted and automatically closing when it is pulled out through the mechanical linkage between the flip cover 1 and the multi-level protection mechanism, effectively preventing abnormal contact with live sockets and improving electrical safety.
