Description

Technical Field

[0001] The utility model relates to the technical field of electricity, in particular to a bottom secondary power connection structure. Background Art

[0002] A socket, also known as a power socket or a switch socket. A socket refers to a seat into which one or more circuit wiring can be inserted, and various wirings can be inserted through it. Usually, socket sets are provided with socket sleeves, and its main function is to provide a current path to ensure stable and safe conduction when a plug is inserted. As an indispensable electrical accessory in daily life, the safety, convenience and intelligent level of sockets are attracting more and more attention. During the power connection process of a socket, since the metal parts of the plug and the socket are in direct contact, electric sparks often occur instantaneously when the power is turned on. Such electric sparks may not be noticeable in an ordinary environment, but under specific conditions, such as in a flour mill, a wood processing workshop and other places with dense dust, the electric sparks are likely to become the ignition source for triggering dust explosion, posing a safety hazard.

[0003] In the prior art, the power connection of sockets basically adopts a direct connection method, that is, as long as the plug is inserted into the socket, the pins of the plug contact the socket sleeves inside the socket to achieve the conduction of the circuit. From a physical point of view, electric sparks are bound to occur instantaneously during power connection, and the electric sparks will corrode the plug and the socket sleeves. Long-term electric corrosion will cause the plug and the socket sleeves to burn out, thus shortening the service life of the plug and the socket sleeves, and easily causing poor contact and loose virtual connection between the plug and the socket, further causing the temperature to rise and leading to the occurrence of electrical fires, reducing the use safety. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a bottom secondary power connection structure, aiming to solve the problems that when the existing plug is inserted into the socket, electric sparks are easily generated, the pins of the plug are prone to ablation phenomenon, the service life is shortened, and the use safety is reduced.

[0005] To achieve the above purpose, the utility model provides a bottom secondary power connection structure, which is arranged in a socket for conductive connection between a plug and the socket, and includes a static piece, a moving piece and a flexible sleeve. An isolation chamber is formed in the socket. The static piece is detachably connected to the wiring terminal inside the socket. One end of the static piece extends into the isolation chamber. The moving piece is rotatably installed on the side wall of the isolation chamber through the flexible sleeve. The two ends of the moving piece are respectively a conductive end and a conduction end. The conductive end extends into the isolation chamber and is used to abut against the static piece. The conduction end extends out of the isolation chamber and is used to abut against the pin of the plug. And the length from the conductive end to the flexible sleeve is greater than the length from the conduction end to the flexible sleeve.

[0006] Preferably, an elastic member is arranged between the conduction end and the bottom surface of the isolation chamber.

[0007] Preferably, one end of the stationary piece extending into the isolation chamber extends towards the bottom of the isolation chamber and bends to form an abutting end, and the abutting end is parallel to the bottom surface of the isolation chamber.

[0008] Preferably, the moving piece bends relative to its center to form the conductive end and the conducting end, and the flexible sleeve is arranged near the conducting end so that the conductive end is inclined relative to the abutting end.

[0009] Preferably, a fixed contact is detachably mounted on the abutting end, and a movable contact for abutting against the fixed contact is detachably mounted on the conductive end.

[0010] Preferably, a limiting block is detachably mounted on one side of the conducting end away from the elastic member, and a limiting hole for inserting a pin is formed in the limiting block.

[0011] Preferably, limiting bosses are respectively formed on one side of the conducting end away from the limiting block and on the bottom surface of the socket, the elastic member is a spring, and the two limiting bosses respectively extend into the two ends of the elastic member and abut against the elastic member.

[0012] Preferably, a through hole for accommodating the flexible sleeve is formed in the side wall of the isolation chamber, mounting holes are formed in the two opposite side hole walls of the through hole, and protrusions for plugging and matching with the mounting holes are respectively formed on the two sides of the flexible sleeve.

[0013] Beneficial effects:

[0014] 1. During the use of a bottom secondary power connection structure of the present utility model, if the plug is not inserted in place and the conductive end of the moving piece does not abut against the stationary piece, the socket cannot transmit electric energy to the plug at this time, thereby effectively avoiding electric shock accidents caused by the plug not being inserted in place, reducing potential safety hazards, and improving the use safety of the socket.

[0015] 2. Since secondary power connection is formed between the moving piece and the stationary piece, the electric spark generated when the plug and the socket are conductively connected is generated at the moving piece and the stationary piece, thereby protecting the pins and effectively preventing the pins from being ablated due to the electric spark, and prolonging the service life of the plug.

[0016] 3. A bottom secondary power connection structure of the present utility model can achieve rapid abutment between the conductive end and the stationary piece, effectively reduce the generation of electric arcs, prolong the service life of the moving piece and the stationary piece, and is reliable in use.

[0017] 4. The secondary bottom electrical connection structure of the present utility model can be used in cooperation with the protection door at the socket jack to prevent children's fingers or other foreign objects from reaching into the socket and causing electric shock accidents, further improving the safety of using the socket.

[0030] Embodiment 1:

[0031] The present utility model provides a bottom secondary power connection structure.

[0032] In an embodiment of the present utility model, a bottom secondary power connection structure is arranged in a socket for conductive connection between a plug 100 and the socket. It includes a static piece 1, a moving piece 2 and a flexible sleeve 5. An isolation chamber 4 is formed in the socket. The static piece 1 is detachably connected to the wiring terminal in the socket. One end of the static piece 1 extends into the isolation chamber 4. The moving piece 2 is rotatably installed on the side wall of the isolation chamber 4 through the flexible sleeve 5. The two ends of the moving piece 2 are respectively a conductive end 6 and a conducting end 7. The conductive end 6 extends into the isolation chamber 4 and is used to abut against the static piece 1. The conducting end 7 extends out of the isolation chamber 4 and is used to abut against the pin of the plug 100. And the length from the conductive end 6 to the flexible sleeve 5 is greater than the length from the conducting end 7 to the flexible sleeve 5.

[0033] Specifically, as Figures 1 to 4 shown, in a bottom secondary electrical connection structure of the present utility model, since an isolation chamber 4 is formed in the socket, the moving blade 2 and the static blade 1 can be stably installed in the isolation chamber 4. That is, a stable installation environment can be provided through the isolation chamber 4 to ensure that the moving blade 2 and the static blade 1 can be correctly installed and cooperate. Further, since one end of the static blade 1 extends into the isolation chamber 4, the moving blade 2 is rotatably installed on the side wall of the isolation chamber 4 through a flexible sleeve 5, and the conductive end 6 of the moving blade 2 extends into the isolation chamber 4, and the conduction end 7 of the moving blade 2 extends out of the isolation chamber 4. When the plug 100 is inserted, the pin of the plug 100 abuts against the conduction end 7 and can thereby push the moving blade 2 to rotate relative to the isolation chamber 4, so that the conductive end 6 of the moving blade 2 abuts against the static blade 1 to form an electrical conduction path, and thus the electrical connection between the plug 100 and the socket can be completed. The structural design is simple and reasonable.

[0034] It can be understood that during the process of inserting the plug 100 into the socket, the top of the pin first abuts against the conduction end 7 of the moving blade 2, thereby realizing the primary electrical connection between the plug 100 and the moving blade 2; as the plug 100 continues to penetrate, the pin continuously pushes the moving blade 2 and enables the moving blade 2 to rotate relative to the isolation chamber 4, so that the conductive end 6 of the moving blade 2 can abut against the static blade 1, and thus the secondary electrical connection between the moving blade 2 and the static blade 1 can be realized. Obviously, the socket can supply power to the plug 100 only after the plug 100 is completely inserted, that is, after the moving blade 2 and the static blade 1 complete the secondary electrical connection. If the plug 100 is not inserted in place and the conductive end 6 of the moving blade 2 does not abut against the static blade 1, the socket cannot transmit power to the plug 100 at this time, thereby effectively avoiding electric shock accidents caused by the plug 100 not being inserted in place, reducing potential safety hazards, and improving the use safety of the socket; at the same time, since there is a secondary electrical connection between the moving blade 2 and the static blade 1, the electric spark generated when the plug 100 is electrically connected to the socket occurs at the moving blade 2 and the static blade 1, and thus the pin can be protected, effectively preventing the pin from being ablated due to the electric spark and extending the service life of the plug 100.

[0035] It should be noted that since the moving blade 2 is rotatably installed on the side wall of the isolation chamber 4 through a flexible sleeve 5, and the length from the conductive end 6 to the flexible sleeve 5 is greater than the length from the conduction end 7 to the flexible sleeve 5, when the plug 100 is inserted, the conduction end 7 moves under the push of the pin, and at this time the flexible sleeve 5 undergoes elastic deformation. According to the lever principle, when the pin pushes the conduction end 7 to move a certain distance, the conductive end 6 will correspondingly move a longer distance, so as to realize the rapid abutment of the conductive end 6 and the static blade 1, effectively reducing the generation of electric arcs, extending the service life of the moving blade 2 and the static blade 1, and being reliable in use.

[0036] It should be noted that the flexible sleeve 5 can be made of flexible materials such as silicone or rubber, so that the flexible sleeve 5 not only has a certain elasticity. It can be understood that when the plug 100 is pulled out, the conducting end 7 of the moving piece 2 can automatically reset to the initial position under the action of the rebound of the flexible sleeve 5, and the conducting end 6 also resets synchronously and separates from the static piece 1, so that the secondary power connection between the moving piece 2 and the static piece 1 can be automatically cut off. That is, when the plug 100 is not inserted or not fully inserted, the moving piece 2 is in a power-off state. This automatically resetting power-off function can be used in cooperation with the protection door at the socket jack to prevent children's fingers or other foreign objects from reaching into the socket and causing an electric shock accident, further improving the safety of using the socket. In addition, a limiting rib for abutting against the moving piece 2 is formed on the inner wall of the socket at the position corresponding to the flexible sleeve 5, thereby preventing the moving piece 2 from being twisted during rotation and causing the conducting end 7 to lose contact, and the use is reliable.

[0037] In one embodiment, as Figure 1 shown, an elastic member 3 is provided between the conducting end 7 and the bottom surface of the isolation chamber 4. It can be understood that when the flexible sleeve 5 is deformed and fails after repeated plugging and unplugging of the plug 100, the secondary power connection between the moving piece 2 and the static piece 1 can still be automatically cut off through the rebound action of the elastic member 3, and the use is reliable.

[0038] In one embodiment, as Figure 1 shown, one end of the static piece 1 extending into the isolation chamber 4 extends towards the bottom of the isolation chamber 4 and is bent to form an abutting end 8, and the abutting end 8 is parallel to the bottom surface of the isolation chamber 4. Specifically, since the abutting end 8 is parallel to the bottom surface of the isolation chamber 4, a large contact area can be formed when the abutting end 8 contacts the conducting end 6 of the moving piece 2, which helps to reduce the contact resistance and improve the efficiency of current transmission; at the same time, the large contact area can also disperse the contact pressure and reduce the wear or deformation of the static piece 1 caused by excessive local pressure.

[0039] In one embodiment, the moving piece 2 is bent relative to its center to form a conducting end 6 and a conducting end 7, and the flexible sleeve 5 is arranged close to the conducting end 7 so that the conducting end 6 is inclined relative to the abutting end 8. Specifically, as Figure 1 and Figure 3As shown, since the movable piece 2 is bent relative to its center to form the conductive end 6 and the conducting end 7, the conductive end 6 can form a certain tilt angle relative to the abutting end 8 of the static piece 1 under the restriction of the flexible sleeve 5, which is conducive to the conductive end 6 of the movable piece 2 to be in contact with the abutting end 8 more stably when the plug 100 is inserted. Further, by arranging the flexible sleeve 5 close to the conducting end 7, not only the movable piece 2 can be stably mounted on the side wall of the isolation chamber 4, but also the movable piece 2 is insulated and protected, and the movable piece 2 can maintain a stable track during the rotation process through the flexible sleeve 5, effectively avoiding excessive displacement or shaking of the movable piece 2, and improving the stability of the rotation of the movable piece 2.

[0040] In one embodiment, if Figure 1 and Figure 3 As shown, a fixed contact 9 is detachably mounted on the abutting end 8, and a movable contact 10 for abutting the fixed contact 9 is detachably mounted on the conductive end 6. It can be understood that in the actual production process of the utility model, a structure for mounting the fixed contact 9, such as a threaded hole, a slot or a spring clip, is provided on the abutting end 8 and the conductive end 6, so that the fixed contact 9 and the movable contact 10 can be firmly mounted on the abutting end 8 and the conductive end 6 respectively by threaded connection, snap-on fixing or spring clamping, etc., and the structural design is simple and reasonable; at the same time, after long-term use of the utility model, if a fixed contact 9 or a movable contact 10 is damaged, the maintenance personnel can disassemble and replace it separately without replacing the entire static sheet 1 or the movable sheet 2, thereby reducing the maintenance cost and time. Further, the fixed contact 9 and the movable contact 10 are used to replace the abutting end 8 to contact the conductive end 6, thereby ensuring that the static sheet 1 and the movable sheet 2 can form a stable, low-resistance conductive path when in contact, thereby improving the reliability of the conductive connection.

[0041] In one embodiment, if Figures 1 to 3 As shown, a limit block 11 is detachably mounted on the side of the conducting end 7 away from the elastic member 3, and a limit hole for inserting the plug pin is provided on the limit block 11. It can be understood that when the plug pin is inserted into the limit hole, the limit hole can clamp and limit the plug pin, effectively preventing the plug 100 from loosening or falling off due to vibration or external force, thereby improving the connection stability between the plug 100 and the socket. Furthermore, the limit block 11 and the conducting end 7 can be detachably mounted in a threaded connection, etc., so that the user can disassemble, repair and replace the limit block 11.

[0042] In one embodiment, if Figure 1As shown, on one side of the conducting end 7 away from the limiting block 11 and on the bottom surface of the socket, limiting bosses are respectively formed correspondingly. The elastic member 3 is a spring. The two limiting bosses respectively extend into the two ends of the elastic member 3 and abut against the elastic member 3, so as to be able to limit the two ends of the spring, thereby preventing the spring from being displaced during the rotation of the moving piece 2 and improving the stability of the overall structure.

[0043] In one embodiment, through holes 12 for accommodating the flexible sleeve 5 are formed on the side wall of the isolation chamber 4. Mounting holes 13 are formed on the two opposite side hole walls of the through holes 12. Protrusions 14 for plugging and cooperating with the mounting holes 13 are respectively formed on the two sides of the flexible sleeve 5. Specifically, as Figures 1 to 4 shown, since through holes 12 are formed on the side wall of the isolation chamber 4, the through holes 12 can be formed as waist-shaped holes, thereby being able to meet the installation requirements for the rotation of the flexible sleeve 5 and the moving piece 2, and the structural design is simple and reasonable. Further, since mounting holes 13 are formed on the two opposite side hole walls of the through holes 12, by respectively plugging and cooperating the protrusions 14 on the two sides of the flexible sleeve 5 with the two mounting holes 13, the stability of the rotation of the flexible sleeve 5 can be ensured.

[0044] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
