Description

Technical Field

[0001] This utility model belongs to the field of power socket manufacturing, and specifically relates to a socket module. Background Technology

[0002] As a key interface for power transmission, socket modules are widely used in scenarios such as public smart charging for electric bicycles. With the rapid development of public smart charging technology for electric bicycles, the demand for intelligent charging sockets is becoming increasingly apparent, especially in terms of real-time sensing of plug insertion / removal status to achieve proactive power-off, billing start / stop, and other safety control functions. However, traditional socket modules have significant technical bottlenecks in this area. Current status detection mechanisms are generally lacking; the protective shutter design of most conventional socket modules only meets basic electric shock prevention requirements, and there is no effective linkage between its opening / closing action and the control system. This design, in abnormal situations (such as the plug being forcibly unplugged during electric bicycle charging), prevents the control system from timely obtaining the plug's status feedback signal, resulting in a delayed abnormal power-off. Furthermore, when the plug is reinserted, the system may not be able to recognize the status change, further increasing the risk. Utility Model Content

[0003] The purpose of this utility model is to provide a socket module that can monitor the plug insertion / removal status by monitoring changes in the position of the protective door.

[0023] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0024] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0025] The structure of the socket module in this embodiment of the utility model is as follows: Figures 1 to 5 As shown, it includes a housing 1, a socket 2, a protective door 3, and a spring 4. The protective door 3 can slide relative to the housing 1, and the spring 4 provides a restoring force for the protective door 3. In normal operation, the protective door 3 is closed, blocking the socket 2 on the socket module, so that the external conductor cannot directly contact the socket 2 through the socket. In use, when the plug is inserted into the socket, it will push the protective door 3 to slide open, thereby enabling the plug to contact the socket 2. The protective door 3 is provided with a trigger structure to trigger an external switch 5 when the protective door 3 is in the open state. In practical applications, the external switch 5 can be fixed to the housing 1 or to an external component. In practical applications, the external switch 5 is connected to the control system. When the protective door 3 is in the open state, the external switch 5 is triggered by the trigger structure. When the protective door 3 moves to the closed state, the trigger structure removes the trigger on the external switch 5, thus realizing real-time monitoring of the state of the protective door 3, that is, real-time monitoring of the plug insertion and removal state. The socket module of this utility model embodiment, through optimized design, not only improves electrical safety, but also enhances the convenience of user operation and the intelligence of the control system.

[0026] The triggering structure includes a protrusion 31 on the protective door 3. A clearance opening 10 is provided on the housing 1 corresponding to the protrusion 31. When the protective door 3 is open, the protrusion 31 extends out through the clearance opening 10, thereby triggering the external switch 5 through the protrusion 31. Specifically, the external switch 5 can be a mechanical switch such as a micro switch or a tactile switch. When the protective door 3 is open, the external switch 5 is triggered by the protrusion 31 directly touching it.

[0027] In another embodiment, when the external switch 5 is a magnetic induction switch, the triggering structure further includes a magnet 32 ​​fixed on the protective door 3. When the protective door 3 is open, the magnetic induction switch is triggered by the magnet 32 ​​approaching it; see Figure 5 As shown, magnet 32 ​​is fixed to protrusion 31. Of course, in practical applications, magnet 32 ​​can also be fixed to other positions on the protective door 3. To ensure reliable fixing of magnet 32, a fixing groove 33 is further provided on the protective door 3 (such as protrusion 31), and magnet 32 ​​is fixed in the fixing groove 33. In actual operation, magnet 32 ​​can be embedded into fixing groove 33 by tight fitting, or it can be glued to fixing groove 33.

[0028] See Figure 3 and Figure 4 The housing 1 includes a housing base 11 with a recess, a pressure plate 12 installed in the recess, and a housing cover 13 covering the upper end of the housing base 11; the insert 2 is installed in the recess and is located below the pressure plate 12; the protective door 3 is slidably installed in the gap between the housing cover 13 and the pressure plate 12, and the spring 4 is disposed between the protective door 3 and the pressure plate 12 or the housing cover 13; the housing cover 13 and the pressure plate 12 are provided with insertion holes 14 at positions opposite to the insert 2, the insertion holes 14 are used for inserting a plug, the pressure plate 12 can limit the installation of the insert 2, and at the same time provide stable support for the protective door 3 to ensure the stability of the structure.

[0029] To enhance the insulation performance between different inserts 2, a partition 15 is provided in the cavity to separate the different inserts 2. The partition 15 effectively enhances the electrical isolation between the inserts 2 and can reduce the potential short circuit risk. The bottom of the pressure plate 12 is supported by the upper end of the partition 15 and is pressed down and limited by the cover 13. The pressure plate 12 forms a downward blocking limit on the insert 2. During assembly, the insert 2 is inserted into the cavity, and then the pressure plate 12 is inserted into the cavity and forms a blocking limit on the insert 2. When the cover 13 is further installed on the upper end of the housing 11, the cover 13 can block and limit the pressure plate 12, ensuring the reliability of the pressure plate 12.

[0030] See Figure 4The upper end of the partition plate 15 is provided with a positioning protrusion 16, and the pressure plate 12 is provided with a positioning hole 17 that cooperates with the protrusion 16. The positioning effect of the pressure plate 12 can be strengthened by the cooperation of the positioning protrusion 16 and the positioning hole 17, thereby enhancing the fixing reliability of the pressure plate 12. The cooperation between the positioning protrusion 16 and the positioning hole 17 is preferably an interference fit.

[0031] Furthermore, the cover 13 is connected to the base 11 by a snap-fit ​​structure; for example, a number of slots are provided on the base 11 and a number of snaps are provided on the cover 13 accordingly, so that the cover 13 and the base 11 are quickly and reliably fixed by the snaps engaging with the slots.

[0032] To facilitate wiring, the socket 2 is provided with a wiring pin 21 extending out of the housing 1. The external power cord is connected through the wiring pin 21 to supply power to the socket module. To enhance the wiring firmness, a wire-holding groove 22 is provided on the wiring pin 21. When wiring, the external power cord is placed into the wire-holding groove 22 and then soldered to fix it, thereby avoiding the problem of the wiring easily loosening or falling off due to vibration or pulling.

[0033] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
