Description

Technical Field

[0001] The invention relates to the technical field of power sockets, in particular to a high-safety discharge socket. Background Art

[0002] In existing electric vehicles powered by battery systems, in order to adapt to different usage scenarios and usage requirements, an integrated charging system is provided, which requires a matching discharge socket. Existing discharge sockets generally have more than one socket to connect to the power supply. This access socket is open, which is prone to electric shock due to misoperation, and is also prone to foreign objects entering by mistake or being corroded by water vapor in the external environment. Therefore, a safety door that blocks the socket is provided in the existing socket for protection, as disclosed in publication number CN 106532323 A. However, for electric vehicles, the voltage connected during charging is relatively high, and simply providing a safety door structure is not enough to ensure its safety in use.

[0003] As disclosed in publication number CN 102544916 A, a micro switch is provided in the socket panel to detect whether the plug is inserted, thereby ensuring the normal operation of the charging mode of the electric vehicle. However, the socket panel in this solution only supports three-hole plugs and cannot be adapted to two-hole plugs. On the other hand, the trigger end of the micro switch is triggered by sliding through the side slope of the safety door, and there is an angle between the moving direction of the trigger end and the moving direction of the side slope. Such a driving method can easily damage the trigger end of the micro switch and cause the trigger to fail or become unstable, and even the position of the entire micro switch can easily cause movement, resulting in deviation in the trigger, making it difficult to ensure safety for long-term use.

[0006] Preferably, the inner cavity of the plug-in module is divided into a first accommodating cavity and a second accommodating cavity from the outside to the inside, and the second accommodating cavity is provided with a first accommodating groove for accommodating the control switch and the movable part and a group of second accommodating grooves for accommodating the socket, the top of the first accommodating groove is an opening, and the top of the second accommodating groove is a connecting hole matching the socket.

[0007] Preferably, a group of the sockets constitutes at least a pair of electrical sockets, and a safety door is provided on the top of each pair of the electrical sockets. The safety door is slidably arranged in the first accommodating cavity, and the top surface of the safety door has a first driving inclined surface. First return springs are respectively abutted between the two ends of the safety door and the inner cavity wall of the core module. In an initial state, the safety door is located on the top of the pair of electrical sockets and blocks the connecting holes on the top of the pair of electrical sockets. When the plug is inserted, the plug pushes the safety door horizontally through the first driving inclined surface to open the connecting hole for connection with the socket.

[0008] Preferably, guide strips are provided on both sides of the top of the first receiving groove, and the bottom surface of the safety door has a slide groove matching the guide strips, so that the safety door can translate along the first receiving groove; the top of the movable member elastically protrudes outward from the first receiving groove, and the safety door can drive the movable member to move axially by translating along the first receiving groove.

[0009] Preferably, the movable part includes a connected head and a rod, the head has first connecting arms on both sides, the extending end of the first connecting arm forms a hook to engage with the top edge of the first accommodating groove; the rod extends axially and faces the trigger end, and grooves are formed on the inner sides of both sides to slide and engage with the side wall convex strips of the first accommodating groove; the rod has second connecting arms on both sides, the second connecting arm is sleeved with a second return spring, and the other end of the second return spring abuts against the side connecting block of the first accommodating groove.

[0010] Preferably, a second driving inclined surface is arranged on the top surface of the first connecting arm and / or the bottom surface of the safety door.

[0011] Preferably, the top cover of the core module is provided with a pressure cover, the center of the pressure cover is hollow to avoid the connecting hole, a limit block is provided on the bottom of the first accommodating cavity, and the bottom of the safety door is engaged with the limit block to maintain the initial state.

[0017] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments are not limited to the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0019] like Figures 1 to 7 As shown, the present invention discloses a high-safety discharge socket, comprising a socket housing 1 having a hollow cavity, wherein a PCB substrate 3 and a plug core module 4 are arranged in the hollow cavity, wherein a group of plug sleeves 401 for connecting a plug are built in the plug core module 4, wherein a jack 101 matching a group of the plug sleeves 401 is arranged on the panel, and a tail end of a group of the plug sleeves 401 is arranged on the PCB substrate 3, and the two are electrically connected through a connecting circuit, wherein a control switch 5 of the connecting circuit is fixedly arranged on the PCB substrate 3 and built in the plug core module 4, wherein the extending direction of the control switch 5 is consistent with that of the plug sleeve 401, and a trigger end 5 of the control switch 5 is connected to the PCB substrate 3 and the PCB substrate 3 is connected to the plug core module 4, wherein the ... 01 is located at its front end, and the trigger end 501 does not protrude from the front end of the socket 401. A moving part 402 is arranged in the plug core module 4, which is opposite to the trigger end 501 and can trigger the control switch 5 by axially moving relative to the trigger end 501. When the plug is plugged into the socket 401, the moving part 402 is driven to move axially to axially squeeze the trigger end 501, so as to control the control switch 5 to conduct the connection circuit; when the plug is pulled out of the socket 401, the moving part 402 moves axially in the opposite direction to release the trigger end 501, so as to control the control switch 5 to disconnect the connection circuit.

[0020] In this solution, a control switch 5 whose triggering direction is consistent with the insertion direction of the socket 401 is provided on the connection circuit, and a moving member 402 that moves in the same direction as the plug is provided to move synchronously, so that when the plug is inserted into the socket 401, the control switch 5 can be triggered to connect the connection circuit, thereby energizing the socket 401. Conversely, when the plug is pulled out, the control switch 5 is disconnected to disconnect the connection circuit. Such a structure ensures that the socket will be energized only when the plug is correctly inserted into the socket. Any non-plug or abnormal plug insertion, such as mistaken insertion of foreign objects and single-pole insertion of the plug, will not conduct the connection circuit, thereby ensuring the safety of the socket discharge.

[0021] Specifically, the shell of the plug module 4 is preferably integrally formed by injection molding, and it can also be composed of a plurality of cavities. The inner cavity of the plug module 4 is divided into a first accommodating cavity 403 and a second accommodating cavity 404 from the outside to the inside, and the second accommodating cavity 404 is provided with a first accommodating groove 405 for accommodating the control switch 5 and the moving part 402 and a group of second accommodating grooves 406 for accommodating the plug sleeve 401, and the top of the first accommodating groove 405 is open to leave space for the moving part 402 to move. The top of the second accommodating groove 406 is a connecting hole 407 that matches the plug sleeve 401, so that the plug can be inserted and plugged into the plug sleeve 401.

[0022] A group of sockets 401 at least constitutes a pair of sockets, a pair of sockets is a live socket and a neutral socket, and a pair of sockets can form a two-hole socket to connect a two-pin plug; a group of sockets 401 can also include a pair of sockets and a grounding socket to form a three-hole socket to connect a three-pin plug. A group of sockets 401 can also include two pairs of sockets and a grounding socket to form a national standard five-hole socket to meet the needs of two-hole and three-hole plugs respectively.

[0023] A safety door 408 is provided on the top of each pair of the power sockets, and the safety door 408 is slidably set in the first accommodating cavity 403. The top surface of the safety door 408 has a first driving inclined surface 4081, and first reset springs 409 are respectively abutted between the two ends of the safety door 408 and the inner cavity wall of the plug core module 4. In the initial state, the safety door 408 is located on the top of a pair of the power sockets and blocks the connecting holes 407 on the top of the pair of the power sockets; when the plug is inserted, the plug pushes the safety door 408 horizontally through the first driving inclined surface 4081 to open the connecting hole 407 and connect with the socket 401.

[0024] The safety door 408 is provided to cover the connection hole 407 so that the socket is isolated from the outside world when not in use to prevent foreign objects from entering by mistake or corrosion from the external environment. At the same time, the top of the movable member 402 protrudes out of the first accommodating groove 405 and extends into the first accommodating cavity 403, so that a linkage is formed between the safety door 408 and the movable member 402. When the plug is inserted and the safety door 408 is pushed open, the movable member 402 is driven to move axially to provide an axial extrusion force to the top trigger end 501 of the control switch 5 for pressing, so that the moving direction of the movable member 402 is consistent with the pressing direction of the trigger end 501 of the control switch 5, thereby protecting the normal triggering of the trigger end 501 and preventing it from being offset and causing friction failure.

[0025] In the preferred embodiment shown in the figure, two pairs of the power sockets and one ground socket are arranged in the second accommodating chamber 404 to form a national standard five-hole socket. Correspondingly, two safety doors 408 are arranged in the first accommodating chamber 403 to respectively shield a pair of the power sockets. Five connecting holes 407 are correspondingly arranged at the bottom of the first accommodating chamber 403. The two safety doors 408 are arranged symmetrically, and the two first return springs 409 are respectively abutted against the inner ends of the two safety doors 408 to respectively realize the mobility of the safety doors 408.

[0026] In order to improve the movement stability of the safety door 408, guide bars 410 are provided on both sides of the top of the first accommodating groove 405, and the bottom surface of the safety door 408 has a slide groove 4082 matching the guide bar 410, so that the safety door 408 can translate along the first accommodating groove 405. The top cover of the ferrule module 4 is provided with a pressure cover 411, which is used to limit the axial position of the safety door 408 and the first return spring 409. The side of the pressure cover 411 is provided with a buckle to engage with the clamping block on the outer wall of the shell of the ferrule module 4, and the center of the pressure cover 411 is hollow to avoid the connection hole 407.

[0027] A limit block 412 is provided on the bottom of the first accommodating cavity 403, and the bottom of the safety door 408 is engaged with the limit block 412 to maintain the initial state. The inner side surface of the limit block 412 is an inclined surface to facilitate the reset of the safety door 408.

[0028] The top of the moving member 402 elastically protrudes out of the first receiving groove 405 , and the safety door 408 can drive the moving member 402 to move axially by moving along the first receiving groove 405 .

[0029] Specifically, Figure 5-Figure 7 As shown, the moving member 402 includes a connected head and a rod, and the head has first connecting arms 4021 on both sides, and the extended end of the first connecting arm 4021 forms a hook 4022 to engage with the top edge of the first accommodating groove 405 to limit the limit position of the moving member 402. The rod extends axially and faces the trigger end 501, and grooves 4023 are formed on the inner sides of the two sides to slide and engage with the side wall convex strips 4051 of the first accommodating groove 405 to limit the stable axial movement of the moving member 402 along the first accommodating groove 405. The rod has second connecting arms 4024 on both sides, and the second connecting arms 4024 are sleeved with a second return spring 4025, and the other end of the second return spring 4025 abuts against the side connecting block 4052 of the first accommodating groove 405 to help the moving member 402 reset.

[0030] Preferably, in order to adapt to the structure of the two safety doors 408, the moving member 402 is preferably a symmetrical structure. Further, in order to improve the linkage smoothness between the safety door 408 and the moving member 402, a second driving inclined surface 4026 is provided on the top surface of the first connecting arm 4021 and / or the bottom surface of the safety door 408.

[0031] Further, in a preferred embodiment, in the initial state of the safety door 408, the moving member 402 is driven by the second return spring 4025 to be located at its upper limit position, at which time the bottom of the rod of the moving member 402 just contacts the trigger end 501 but does not squeeze the trigger end 501, and the safety door 408 does not move. Such a structure enables the moving member 402 to be driven to move axially once the safety door 408 is released from the initial state and starts to move, so as to synchronously squeeze the trigger end 501, which not only satisfies the synchronization of the two but also minimizes the required moving stroke of the moving member 402.

[0032] like Figure 2-Figure 4 As shown, the connection circuit also includes a first relay 6, a second relay 7, a fuse 8 and a group of wiring terminals 9 arranged on the PCB substrate 3. Specifically, a group of the wiring terminals 9 includes an L-in terminal, an L-out terminal, an N terminal, a PE terminal, and a CN2 terminal. The working principle of the connection circuit is: the positive current is input from the L-in terminal to the first relay 6, and then output from the L-out terminal, and the socket current passes through the fuse 8 and the second relay 7 to the neutral wire socket; the negative current input and output are shared, the N terminal is connected to the live wire socket and then output through the CN2 terminal. The PE terminal is connected to the ground socket and shares the same ground as the signal negative pole.

[0033] The fuse 8 is connected in the connection circuit to limit the current range that the connection circuit can pass. When the current is too large, the fuse 8 cuts off the connection circuit by melting to protect the components inside the socket and prevent the risk of fire caused by overheating.

[0034] Furthermore, an indicator light 10 is connected to the connection circuit, and the top of the indicator light 10 is embedded in the socket housing 1 to display the connection circuit by lighting or extinguishing. Specifically, when the plug is inserted and the control switch 5 is triggered to turn on the connection circuit, the first relay 6 and the second relay 7 are energized, and the indicator light 10 emits a high light, indicating that the socket starts to work; when the plug is pulled out, the control switch 5 is released, the connection circuit is disconnected, the first relay 6 and the second relay 7 are disconnected, and the indicator light 10 is extinguished, indicating that the socket is closed. The indicator light 10 is an LED lamp, preferably built into the plug module 4. Of course, in other feasible embodiments, the indicator light 10 can also be set at other parts to display the connection of the connection circuit by light, to visualize the connection circuit, which is simple and clear, and can be convenient for users to use.

[0035] On the other hand, a temperature control switch (not shown in the figure) is also provided on the PCB substrate 3, and the temperature control switch is connected to the connection circuit. When the temperature inside the socket or the temperature of the PCB substrate 3 is too high, the connection circuit is cut off and the power supply to the socket 401 is stopped.

[0036] The socket housing 1 is formed by a lower shell and an upper cover being clamped together. In other feasible embodiments, the socket housing 1 can also be formed in other ways, such as integrally formed. The socket housing 1 can be provided with mounting holes and steel sleeves to form a connection structure that can be connected and fixed with other components. The PCB substrate 3 is fixedly connected to the socket housing 1 by screws to ensure the stability of its installation.

[0037] The present invention forms a mechanical structure by setting a moving part 402 and a control switch 5 to control the conduction of the connection circuit, forming a first safety protection structure; a fuse 8 is set to control the current range, forming a second safety protection structure; a temperature control switch is set to control the range of the internal temperature of the socket, forming a third safety protection structure. The present invention effectively protects the safe use of the socket through a triple safety protection structure, and minimizes the risk of use.

[0038] It should be understood that although this specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each implementation mode may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0039] The series of detailed descriptions listed above are only specific descriptions of feasible implementation methods of the present invention. They are not intended to limit the scope of protection of the present invention. Any equivalent implementation methods or changes that do not deviate from the technical spirit of the present invention should be included in the scope of protection of the present invention.
