Description

Technical Field

[0001] This utility model relates to the field of plug and socket electrical connectors, and more particularly to protective doors. Background Technology

[0002] In modern homes and offices, electrical outlets serve as crucial interfaces for power transmission, and their safety and reliability directly impact daily life. Currently, most outlets on the market employ a safety design with protective shutters, a feature that has become an important standard for evaluating outlet quality.

[0003] The safety shutter works on a precise mechanical linkage mechanism: when a user inserts a plug into the socket, the plug's pin must first overcome the spring resistance of the safety shutter, opening it to a certain angle and distance before establishing a stable electrical connection with the internal conductive copper contacts. After the plug is removed, the safety shutter quickly resets under the restoring force of the built-in spring, tightly sealing the socket's opening. Therefore, the safety shutter inside the socket provides significant dual safety protection: firstly, it prevents dust, liquids, and other foreign objects from entering the socket, avoiding short circuits or arcing caused by contaminant accumulation; secondly, it prevents electric shock accidents caused by children or adults inserting fingers, metal objects, etc., into the socket out of curiosity or negligence.

[0004] However, while existing sockets can improve safety through their protective doors, the design of these doors, which typically feature a slanted opening (i.e., there is a slanted opening between the protective door and the socket cover to facilitate plug insertion), always leaves a gap between the protective door and the cover. This results in poor waterproofing and dustproofing at the protective door, allowing liquids and dust to easily enter the socket and cause safety issues such as leakage and short circuits. Utility Model Content

[0005] The main purpose of this utility model is to provide a protective door that completely seals the socket horizontally, which aims to solve the problem that there are gaps between the existing protective door and the cover, making it difficult to effectively prevent the intrusion of liquids and dust, while improving the waterproof and dustproof performance of the socket itself.

[0006] To achieve the above objectives, this utility model provides a protective door, including a body and a stop bar. The body is movably installed at a preset position at a socket. A through hole is provided on the body at a position corresponding to the socket. The stop bar is horizontally installed in the through hole and is used to close the through hole and the socket. The stop bar can drive the body to move to open the socket by inserting a plug.

[0007] Preferably, mounting holes are respectively provided on the two side walls of the through hole, a rotating shaft is provided on the stop bar, the two ends of the rotating shaft are respectively inserted into the two mounting holes, and a first elastic element for driving the stop bar to rotate relative to the body is sleeved on the rotating shaft.

[0008] Preferably, a protrusion is formed on the side wall of the stop bar, and a boss is formed on the two side walls of the through hole opposite to the protrusion for abutting against the protrusion, and a first slope is formed on the side wall of the boss for the stop bar to abut against.

[0009] Preferably, limiting grooves are respectively formed on the two side walls of the through hole, and the two sides of the stop bar are formed with lugs that slide in contact with the limiting grooves; a second elastic member is provided on the side wall of the stop bar along the extension direction of the limiting groove, and a second slope is formed on the side of the stop bar opposite to the second elastic member.

[0010] Preferably, a guide slope is formed on the wall of the through hole for abutting against the second slope, and the guide slope is inclined from top to bottom toward the direction of the second elastic member.

[0011] Preferably, a baffle is formed at the top of the baffle bar, the baffle extending away from the second slope, the baffle being used to shield the second elastic member; a groove for the insertion of the pin is formed above the second slope, the bottom surface of the groove being inclined from top to bottom away from the second elastic member.

[0012] Beneficial effects:

[0013] This utility model's protective door, through a horizontally installed and movable stop bar within the through hole, can completely seal the through hole and socket, thereby preventing gaps between the protective door and the cover. This effectively blocks liquids and dust from entering the socket, significantly improving the socket's protective performance and reducing the risk of leakage and short circuits. Simultaneously, when the plug is inserted into the socket, the movable stop bar, under the action of the pin, can open the protective door, allowing the plug to pass smoothly through the protective door to achieve connection and power supply, which is both safe and convenient.

[0028] Example 1:

[0029] This utility model proposes a protective door.

[0030] In one embodiment of the present invention, the protective door 100 includes a body 101 and a baffle 102. The body 101 is movably installed at a preset position of the socket. A through hole 103 is provided on the body 101 at the position corresponding to the socket. The baffle 102 is horizontally installed in the through hole 103 and is used to close the through hole 103 and the socket. The baffle 102 can drive the body 101 to move to open the socket by inserting a plug.

[0031] Specifically, such as Figures 1 to 6As shown, in the protective door 100 of this utility model, the main body 101 can be movably installed to a preset position by means of springs or the like. The preset position can be the inside of an existing socket, and a socket hole is opened inside the socket corresponding to the position of the conductive copper sheet. Thus, the main body 101 always maintains the position of blocking the socket hole under the action of the spring, thereby achieving waterproof and dustproof protection for the socket. The structural design is simple and reasonable. Furthermore, since a through hole 103 is provided on the main body 101 at the position corresponding to the socket, and a stop bar 102 is installed horizontally and movably within the through hole 103, the stop bar 102 can be installed in a sliding or rotating manner, and is securely and regulated within the through hole 103 by an elastic element (such as a spring). This allows the stop bar 102 to move relative to the main body 101 when the plug is inserted into or removed from the through hole 103. At the same time, when the plug is not inserted, the stop bar 102 is in a horizontal position relative to the main body 101, which can prevent gaps between the protective door 100 and the socket cover, thereby effectively preventing liquids and dust from entering the socket and ensuring reliable use.

[0032] Understandably, when the plug is inserted into the through hole 103, the plug pin first pushes the stop bar 102 to move independently within the through hole 103 (e.g., deflecting at a certain angle, thus forming an inclined blocking surface before the pin is fully inserted). Since a limiting connection structure (which can be a spring, i.e., the spring is gradually compressed as the stop bar 102 pushes) is provided between the stop bar 102 and the body 101, the body 101 remains stationary at this time, and the through hole 103 is still partially blocked by the stop bar 102. As the pin continues to penetrate deeper, after the stop bar 102 moves to the set stroke, the stop bar 102 drives the body 101 to move and open the socket. The body 101 can drive the stop bar 102 to move synchronously so that the pin can pass through the through hole 103 and fully extend into the socket, thereby realizing the electrical connection between the pin and the conductive copper sheet. The structural design is ingenious and reasonable. In addition, when the plug is unplugged, the stop bar 102 returns to its original position under the action of the spring, thereby re-blocking and sealing the through hole 103 and the socket, thus ensuring the safety protection effect of the socket.

[0033] In one embodiment, mounting holes 104 are respectively provided on the opposite side walls of the through hole 103. A rotating shaft 105 is provided on the stop bar 102, with both ends of the rotating shaft 105 passing through the two mounting holes 104 respectively. A first elastic element 106 for driving the stop bar 102 to rotate relative to the body 101 is sleeved on the rotating shaft 105. Specifically, as shown... Figures 1 to 2As shown, by inserting the rotating shaft 105 on the stop bar 102 into the mounting hole 104, a rotational support structure can be formed, ensuring the smooth rotation of the stop bar 102 within the through hole 103. Furthermore, the first elastic element 106 sleeved on the rotating shaft 105 can be a torsion spring. When the user inserts the plug, the stop bar 102 rotates relative to the body 101 on the rotating shaft 105 under the action of the pin. After rotating to a certain stroke, it drives the body 101 to displace and open the socket. During this process, the first elastic element 106 gradually compresses and stores elastic potential energy. When the user pulls out the plug, the first elastic element 106 releases its elastic potential energy and provides a restoring force to the stop bar 102. This allows the stop bar 102 to automatically reset when not under the action of the pin and always remain in the initial position blocking the through hole 103. This not only ensures smooth rotation and clearance of the stop bar 102 when the pin is inserted but also improves the timeliness of the stop bar 102's protection against foreign objects when the plug is pulled out, making it reliable in use.

[0034] In one embodiment, a protrusion 107 is formed on the side wall of the baffle 102, and bosses 108 for abutting against the protrusion 107 are formed on the opposite side walls of the through hole 103, and a first slope 109 for the baffle 102 to abut against is formed on the side wall of the bosses 108. Figure 2 As shown, when the user inserts the plug, the plug pin abuts against the stop bar 102, which pushes the stop bar 102 to rotate relative to the body 101 until the side wall of the stop bar 102 abuts against the first ramp 109. As the pin continues to be inserted, the stop bar 102 cannot continue to rotate because it abuts against the first ramp 109. However, the body 101 is movably mounted (which can be a spring) at a preset position, thereby converting the vertical insertion force of the pin into a lateral pushing force on the body 101. This drives the body 101 to move and open the socket, thus realizing the electrical connection between the plug and the conductive copper sheet. The structural design is ingenious and reasonable. In addition, during the rotation of the baffle 102, the first elastic element 106 is in a compressed state. When the user pulls out the plug, the first elastic element 106 drives the baffle 102 to rotate in the opposite direction. Since the baffle 102 has a protrusion 107 on its side wall and the two side walls of the through hole 103 have protrusions 108 for abutting against the protrusion 107, the baffle 102 can be prevented from rotating excessively. This ensures that the baffle 102 always remains in the initial position of blocking the through hole 103 when it is not under the action of the pin, thereby ensuring the protection effect against foreign objects and impurities such as liquids and dust.

[0035] In another embodiment, limiting grooves 110 are respectively formed on the two side walls of the through hole 103, and lugs 111 are formed on both sides of the stop bar 102 to slide and engage with the limiting grooves 110; a second elastic member 112 is provided on the side wall of the stop bar 102 along the extension direction of the limiting grooves 110, and a second slope 113 is formed on the side of the stop bar 102 opposite to the second elastic member 112.

[0036] Understandably, such as Figure 3 As shown, when the plug is inserted into the socket, the second ramp 113 of the stop bar 102 abuts against the body 101. As the pin continues to be inserted, the stop bar 102, guided by the second ramp 113 and pushed by the pin, can slide relative to the body 101 along the extending direction of the limiting groove 110. The second elastic element 112 (which can be a spring) is gradually compressed under the push of the stop bar 102. When the spring is in its ultimate compressed state, the stop bar 102 transmits the pushing force of the pin to the body 101 through the spring, allowing the body 101 to move relative to a preset position. The body 101 can synchronously drive the stop bar 102 to move relative to a preset position, thereby allowing the body 101 and the stop bar 102 to open the socket, ultimately enabling the pin to completely pass through the through hole 103 and be inserted into the socket, thus achieving electrical connection between the pin and the conductive copper sheet. The structural design is ingenious and reasonable. At the same time, when the user unplugs the plug, the second elastic element 112 rebounds, thereby pushing the stop bar 102 back to its initial position blocking the through hole 103, ensuring the shielding and protection of the socket and the conductive copper sheet, and preventing the intrusion of liquids, dust, and other impurities. In addition, the sliding contact between the support lug 111 and the limiting groove 110 ensures the smooth and stable movement of the stop bar 102, ensuring the precise control of the movement trajectory of the stop bar 102, preventing the stop bar 102 from getting stuck during sliding, and improving the user's operating feel when inserting the plug.

[0037] In one embodiment, a guide slope 114 is formed on the wall of the through hole 103 for abutting against the second ramp 113. The guide slope 114 slopes downwards towards the second elastic member 112. Specifically, as shown... Figure 3 As shown, the guide slope 114 can increase the contact area between the stop bar 102 and the body 101, thereby efficiently converting the vertical thrust of the pin into a lateral driving force on the stop bar 102 and the body 101, and enabling the stop bar 102 to move smoothly toward the second elastic member 112 to achieve a stable connection between the plug and the conductive copper sheet, making it reliable in use.

[0038] In one embodiment, a baffle 115 is formed at the top of the baffle 102, extending away from the second slope 113, and the baffle 115 is used to shield the second elastic member 112; a groove 116 for the insertion of a pin is formed above the second slope 113, and the bottom surface of the groove 116 slopes downward from top to bottom away from the second elastic member 112. Specifically, as Figure 3As shown, the baffle 115 can cover the second elastic element 112, thereby effectively preventing external foreign objects from hindering the normal compression and rebound of the second elastic element 112, ensuring the reset effect of the stop bar 102 and the driving effect of the body 101. The structural design is simple and reasonable. Furthermore, the inclined bottom surface of the inclined groove 116 can form a guiding engagement with the pin, thereby ensuring that the pin can accurately push the stop bar 102 to move at a predetermined angle when inserted, improving the stability and smoothness of the movement of the stop bar 102.
