Description

Technical Field:

[0001] The utility model relates to the technical field of manufacturing charging devices, in particular to a power socket and a charger with high-reliability limit, which have reasonable structure, simple operation, can ensure reliable insertion of a power supply cable, and thus improve the product quality. Background Art:

[0002] With the development of technology, electrical products are widely used in industrial production and people's lives. Electrical appliances generally require cables for power supply, and existing cables mostly use plugs and sockets to cooperate for power supply. As the use time prolongs, the gap between the socket and the plug increases, which is prone to loosening, and thus problems such as power supply interruption and equipment stoppage may occur. For charging devices, a reliable cable socket and plug mechanism is also crucial. At present, in order to improve the connection reliability of cable terminals that need to be repeatedly plugged and unplugged during use, means such as fixing with heat shrink tubes, fixing with steel bars after drilling holes in the shell, or fixing with clamps are adopted. However, various problems still exist. For example, the fixing method with heat shrink tubes has an ugly appearance, and as the heat shrink tubes age, the fixed part will gradually loosen; fixing with steel bars after drilling holes in the shell involves waterproof treatment of the shell and the direction of fixing screws, etc., and the fixing with clamps is limited by the size of the connector injection molding, and there are often phenomena such as batch fixing not tightly or not being able to be fixed. Summary of the Invention:

[0003] The utility model aims at the defects and deficiencies existing in the prior art, and provides a power socket and a charger with high-reliability limit, which have reasonable structure, simple operation, can ensure reliable insertion of a power supply cable, and thus improve the product quality.

[0005] A power socket with high-reliability limit is provided with a socket body, and a slot matching with a plug is opened on the socket body. It is characterized in that a limiting component for limiting the plug inserted into the slot is further arranged on the socket body. The limiting component is arranged opposite to the slot of the socket, and one end or both ends of the limiting component are hinged on both sides of the slot of the socket. After the plug is inserted into the slot, the plug presses down or lifts the limiting component.

[0006] A bending part for accommodating the plug is opened on the limiting component of the utility model, and the bending part is conformally arranged with the plug, so that when the plug is inserted into the socket, the plug is clamped in the bending part of the limiting component, improving the limiting effect on the plug and preventing the plug from loosening due to shaking up and down in the socket.

[0007] On both sides of the slot of the present utility model, support plates for connecting the limiting components are respectively provided. Hinge holes are formed in the support plates. Connecting shafts are respectively provided at both ends of the limiting component. The limiting component is connected to the hinge holes of the support plates through the connecting shafts. Further, the limiting component is made of a ductile metal or plastic. The limiting component can be rod-shaped or sheet-shaped. When the bent portion of the limiting component is pinched tightly along the width direction, deformation can occur, thereby facilitating the insertion or removal of the connecting shafts at both ends of the limiting component into or from the hinge holes on the support plates.

[0008] The limiting component of the present utility model is made of an elastic metal rod. Connecting shafts for connecting to the hinge holes on the support plates are provided at both ends of the limiting component. The limiting component further includes an extension portion located between the connecting shafts on both sides and bent away from the slot direction.

[0016] Reference numerals: socket body 1, slot 2, bent portion 3, support plate 4, connecting shaft 5, fixing screw 6. Detailed implementation manners:

[0017] The present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] As shown in the Figure 1 accompanying drawings, the present utility model provides a highly reliable power socket, which is provided with a socket body 1. A slot 2 matching with a plug is opened on the socket body 1. The socket body 1 is further provided with a limiting member for limiting the plug inserted into the slot 2. The limiting member is arranged opposite to the slot 2 of the socket. One end or both ends of the limiting member are hinged on both sides of the slot 2 of the socket. After the plug is inserted into the slot 2, the plug presses down or lifts the limiting member.

[0019] A bending portion 3 for accommodating the plug is opened on the limiting member of the present utility model. The bending portion 3 is conformally arranged with the plug, so that when the plug is inserted into the socket, the plug is clamped in the bending portion 3 of the limiting member, improving the limiting effect on the plug and preventing the plug from loosening due to up and down shaking in the socket.

[0020] Support plates 4 for connecting the limiting member are respectively arranged on both sides of the slot 2 of the present utility model. Hinge holes are opened on the support plates 4. Connecting shafts 5 are respectively arranged at both ends of the limiting member. The limiting member is connected to the hinge holes of the support plates 4 through the connecting shafts 5. Further, the limiting member is made of a metal or plastic with toughness. The limiting member can be rod-shaped or sheet-shaped. When the bending portion of the limiting member is pinched tightly along the width direction, it can be deformed, thereby facilitating the insertion or disassembly of the connecting shafts 5 at both ends of the limiting member into the hinge holes on the support plates 4.

[0021] The limiting member of the present utility model is made of an elastic metal rod. Connecting shafts for connecting with the hinge holes on the support plates 4 are arranged at both ends of the limiting member. The limiting member further includes an extension portion located between the connecting shafts on both sides and bent away from the slot direction. A bending portion 3 conformally arranged with the plug is provided in the center of the extension portion.

[0022] The support plate 4 of the present utility model can adopt an L-shaped support plate, with screw holes opened at the bottom and fixed to both sides of the slot 2 through screws. Hinge holes are opened at the upper part for installing the connecting shafts of the limiting member.

[0023] When the above power socket of the present utility model is inserted into the plug, the limiting member rotates along the connecting shaft in the hinge hole of the support plate and abuts against the upper part or the lower part of the plug, so that the plug and the slot do not shake relatively, thereby preventing the plug from loosening from the slot. When the plug needs to be removed, the plug can be pulled out of the slot along the insertion direction.

[0024] The present utility model also provides a charger, which is provided with a charger housing. A power supply cable socket is arranged on the charger housing. The power supply cable socket adopts the above-mentioned highly reliable socket.

[0025] In the charger of the present utility model, the bottom of the support plate is mounted on the socket and is located on the side of the slot.

[0026] Embodiment 1:

[0027] As shown in the attached Figure 1 and the attached Figure 2 As shown, this example provides a fixing structure for a power supply plug, including a limiting component, namely an elastic clamp, a fixing angle piece, namely a support plate 4, fixing screws, and a power socket. The fixing angle piece is fixed to both ends of the power socket through the fixing screws, and the axial two ends of the elastic clamp are sleeved on the fixing angle piece; the elastic clamp is made of stainless steel elastic material, and the two ends are L-shaped structures, which are convenient for sleeving on the fixing angle piece; the middle is a snap structure, which cooperates with the power plug structure; in this example, the fixing angle piece is a stainless steel hard piece, in an L-shaped structure, and through holes are provided on both sides. The through holes on one side are used for fixing the angle piece to the socket, and the through holes on the other side are used for the elastic clamp to pass through. The feature is that the perforation of the elastic clamp is higher than the highest point of the screw of the fixing angle piece, which is convenient for the installation and fixation of the elastic clamp; the fixing angle pieces are used in pairs; the fixing screws cooperate with the fixing angle piece to fix the fixing angle piece and the power socket to the charger body;

[0028] During application, when the power plug is inserted into the power socket, the fixed clamp rotates vertically axially, and the power plug is fixed in an interference fit through the snap structure in the middle of the clamp. When the power cord is stressed, due to the abstract force of the clamp, the power plug is tightly locked by the clamp. When it is necessary to replace the power plug and the power cord, only need to forcefully remove the clamp from the power plug in the vertical extraction direction.

[0029] Compared with the prior art, the present utility model has the remarkable advantages of reasonable structure, simple plugging and unplugging, and can effectively improve the connection stability of the cable.
