Description

Technical Field

[0001] The present application relates to the technical field of charging connectors, and in particular to energy storage connectors. Background Art

[0002] In electronic devices, electrical connectors are usually required to achieve electrical connections between electrically independent components.

[0003] Connectors typically consist of plugs and sockets. In electric vehicles, these energy storage connectors can be used to charge the vehicle. However, during charging, the plug and socket are typically connected only through friction, resulting in a weak connection that can easily loosen, affecting charging performance. Summary of the Invention

[0004] In order to improve the connection strength, the present application provides an energy storage connector.

[0005] The energy storage connector provided in this application adopts the following technical solutions:

[0006] The plug is provided with a self-locking piece, and the end of the self-locking piece is provided with a self-locking block for cooperating with the limiting boss. The side of the self-locking block facing the socket is provided with a plugging inclined surface cooperating with the cooperating inclined surface, and the side of the self-locking block facing away from the socket is provided with a locking surface cooperating with the clamping surface.

[0007] By adopting the above technical solution, when the plug and the socket are plugged in, the connecting tube is inserted into the plug-in slot, and the protective tube is plugged into the limit slot. During the plug-in process, the interference bevel on the limit boss contacts the plug-in bevel of the self-locking block. As the limit boss advances, the self-locking block is gradually lifted up until the self-locking block passes over the interference bevel and collides with the upper surface of the limit boss. The limit boss continues to move forward, and the self-locking block passes over the limit boss. The self-locking block moves downward under the action of its own elastic force and is embedded in the clamping surface of the limit boss. At this time, the locking surface collides with the clamping surface, thereby limiting the limit boss. When the operator inserts the plug into the socket, the self-locking block and the limit boss cooperate with each other to lock the socket and the plug, achieving self-locking. At this time, the plug and the socket are difficult to separate and not easy to loosen, thereby improving the connection strength of the plug and the socket.

[0008] Preferably, the end of the self-locking piece away from the self-locking block is an unlocking end, and both sides of the self-locking piece are connected to the plug through connecting blocks. An unlocking gap is left between the upper surface of the self-locking piece and the socket, and an unlocking tongue is movably connected in the unlocking gap. The unlocking tongue includes a pressing end away from the self-locking block, and the pressing end is located above the unlocking end.

[0009] By adopting the above technical solution, when unlocking, the operator presses the pressing end of the unlocking tongue, and the pressing end applies downward pressure to the unlocking end, and the self-locking piece tilts and rotates around the connecting support block, thereby driving the self-locking block to move upward and lift, so that the locking surface and the card surface are separated, and the limiting boss is unlocked and can slide out normally, which is convenient to use.

[0010] Preferably, a strip-shaped sliding groove is provided in the middle of the self-locking piece, the self-locking block is located at the end of the sliding groove facing the socket, the unlocking tongue is fixed with a slider slidably connected to the sliding groove, and the lower surface of the unlocking tongue is fixed with a limit block facing the side of the connecting support block.

[0011] By adopting the above technical solution, the unlocking tongue can slide along the sliding groove, and the limit block and the sliding groove cooperate with each other to limit the sliding stroke of the unlocking tongue.

[0012] Preferably, an unlocking groove cooperating with the self-locking piece is provided on the lower surface of the unlocking tongue, an anti-touch block located on the outside of the self-locking piece is fixed to the lower surface of the pressing end, and an anti-touch boss facing the unlocking tongue is fixed inside the plug, and when the self-locking piece collides with the end of the unlocking groove away from the socket, the anti-touch block and the anti-touch boss collide directly.

[0013] By adopting the above technical solution, when the plug and socket are connected for charging, the operator pushes the unlocking tongue to slide in the direction of the self-locking block until the self-locking piece contacts the unlocking groove. At this time, the unlocking tongue cannot be pushed further, and the anti-touch block and the anti-touch boss directly contact each other. The anti-touch boss restricts the unlocking tongue, and the operator cannot press down the pressing end, thereby preventing other people from accidentally touching the unlocking tongue and causing it to unlock, causing the plug and socket to loosen. When the operator needs to unlock, he needs to pull the unlocking tongue first, so that the pressing end is offset from the anti-touch boss, and then press down the pressing end to unlock. The unlocking operation is divided into two steps to ensure the self-locking effect.

[0014] Preferably, the end of the slider away from the pressing end is provided with a self-locking end, the lower surface of the self-locking end is provided with an arc-shaped anti-touch ball, and the upper surface of the end of the self-locking block facing the sliding groove is provided with an anti-touch inclined surface that cooperates with the anti-touch ball. When the self-locking piece collides with the end of the unlocking groove away from the socket, the anti-touch ball collides with the side of the self-locking block away from the sliding groove.

[0015] By adopting the above technical solution, the plug and socket are connected, and the operator pushes the unlocking tongue toward the self-locking block. During this pushing process, the anti-touch ball contacts the anti-touch slope and slides along the anti-touch slope to above the self-locking block. As the unlocking tongue continues to push until the self-locking plate contacts the bottom of the unlocking slot, the anti-touch ball passes over the upper surface of the self-locking block and contacts the end face of the self-locking block. At this time, the unlocking tongue is restrained by the anti-touch ball and the self-locking block, preventing the unlocking tongue from sliding backward and unlocking. To unlock, the operator simply pulls the unlocking tongue backward. The curved surface of the anti-touch ball allows it to pass over the surface of the self-locking block and re-engage in the sliding slot.

[0016] Preferably, the lower surface of the slider is provided with a lifting protrusion that cooperates with the limiting boss, and the side of the lifting protrusion facing the self-locking block is provided with a lifting inclined surface that cooperates with the interfering inclined surface.

[0017] By adopting the above technical solution, when the plug is inserted into the socket, the limiting boss first contacts the self-locking block and then contacts the lifting boss. The limiting boss lifts the slider through the lifting inclined surface, making it easier for the operator to push the unlocking tongue.

[0018] Preferably, a connecting groove directly facing the limiting boss is provided on the limiting cylinder, and the self-locking piece is located directly above the connecting groove.

[0019] By adopting the above technical solution, when the plug and the socket are plugged in, the limiting boss is inserted into the connecting groove facing each other, and the connecting groove and the limiting boss are matched to limit the position of the limiting boss, ensuring that the limiting boss is facing each other with the self-locking piece.

[0020] Preferably, the protective cylinder is rotatably connected to the socket.

[0021] By adopting the above technical solution, after the plug and the socket are plugged in, the plug can be rotated around the socket, so that the plug can be plugged in and connected to the socket at multiple angles.

[0022] Preferably, a magnetic pole piece is provided at the end of the self-locking plate facing the socket, a positioning pole piece with a polarity opposite to that of the magnetic pole piece is provided on the limiting boss, and a circle of auxiliary pole pieces with the same polarity as the positioning pole piece is provided at the end of the limiting cylinder, and the inner wall of the auxiliary pole piece is arranged at an angle.

[0023] By adopting the above technical solution, when the plug and the socket are plugged in, it is difficult to align the plug and the socket in one go because each operator holds the plug at a different angle and the position of the upper limit boss on the socket is also different. In order to reduce the inconvenience caused by multiple alignments, an auxiliary alignment mechanism is added. When the operator holds the plug toward the socket for plugging, if the limit boss is not directly facing the self-locking plate, that is, the limit boss is facing the limit cylinder. At this time, the auxiliary pole piece is directly facing the positioning pole piece. Since the auxiliary pole piece and the positioning pole piece have the same polarity, the auxiliary pole piece will generate a repulsive force on the positioning pole piece, and the auxiliary pole piece is tilted. The repulsive force generated on the positioning pole piece and the limit boss is tilted, which will drive the limit boss and the protective cylinder to rotate until the limit boss is directly facing the self-locking plate. The magnetic pole piece and the positioning pole piece generate suction, thereby locking the limit boss, so that the limit boss can be aligned with the connection slot for plugging. During the plugging process, the protective tube can rotate automatically to align the limiting boss and the connecting groove, thereby achieving a one-time successful plugging without the need for multiple alignments, which is easy to use.

[0024] In summary, this application has the following beneficial technical effects:

[0025] The self-locking block and the limiting boss cooperate with each other to lock the socket and the plug, realizing self-locking. The plug and the socket are difficult to separate and not easy to loosen, thereby improving the connection strength of the plug and the socket. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0034] Example

[0035] The embodiment of the present application discloses an energy storage connector, referring to Figure 1 , including a plug 2 and a socket 1 that are plugged into each other.

[0036] Reference Figure 1 The socket 1 is provided with an inner conductor 11 facing the plug 2. A protective sleeve 12 is rotatably connected to the outer ring of the inner conductor 11. The protective sleeve 12 is coaxially arranged with the conductive rod. An annular insertion groove 13 is formed between the protective sleeve 12 and the inner conductor 11. A limiting boss 14 is fixed to the outer wall of the protective sleeve 12. The side of the limiting boss 14 facing the plug 2 is provided with an interfering inclined surface 141, and the side of the limiting boss 14 facing away from the plug 2 is provided with a vertical engaging surface 142. A positioning electrode 15 is provided within the interfering inclined surface 141.

[0037] Reference Figure 1 and Figure 2 The plug 2 is provided with a connecting cylinder 21 for insertion into the insertion slot 13. The plug 2 is also provided with a limiting cylinder 22 located on the outer ring of the connecting cylinder 21. The limiting cylinder 22 and the connecting cylinder 21 are arranged coaxially, and a limiting slot 23 is formed between the limiting cylinder 22 and the connecting cylinder 21. When the plug 2 is connected to the socket 1, the inner conductor 11 is inserted into the inner ring of the connecting cylinder 21, and the protective cylinder 12 is inserted into the limiting slot 23. The limiting cylinder 22 is provided with a connecting slot 221 that mates with the limiting boss 14. The protective cylinder 12 is inserted into the limiting slot 23, and the limiting boss 14 is inserted into the connecting slot 221.

[0038] Reference Figure 1 and Figure 2 The plug 2 is provided with a self-locking piece 3 that is opposite to the connecting groove 221 and located above the connecting groove 221. The self-locking piece 3 is a rectangular sheet structure. The self-locking piece 3 is made of plastic or other materials. The self-locking piece 3 has a certain toughness and can undergo a certain degree of elastic deformation.

[0039] Reference Figure 1 and Figure 2 A magnetic pole piece 35 is fixed to the end of the self-locking piece 3 facing the socket 1. The polarity of the magnetic pole piece 35 is opposite to that of the positioning pole piece 15. The end of the limiting cylinder 22 is provided with a circle of auxiliary pole pieces 222 with the same polarity as the positioning pole piece 15, and the inner wall of the auxiliary pole piece 222 is inclined.

[0040] Reference Figure 1 and Figure 2 When the operator holds the plug 2 and inserts it into the socket 1, if the limiting boss 14 is not directly opposite to the self-locking plate 3, that is, the limiting boss 14 is facing the limiting cylinder 22. At this time, the auxiliary pole piece 222 is directly opposite to the positioning pole piece 15. Since the auxiliary pole piece 222 and the positioning pole piece 15 have the same polarity, the auxiliary pole piece 222 will generate a repulsive force on the positioning pole piece 15. The auxiliary pole piece 222 is tilted, and the repulsive force generated on the positioning pole piece 15 and the limiting boss 14 is tilted, which will drive the limiting boss 14 and the protective cylinder 12 to rotate until the limiting boss 14 is directly opposite to the self-locking plate 3. The magnetic pole piece 35 and the positioning pole piece 15 generate an attractive force, thereby locking the limiting boss 14, so that the limiting boss 14 can be aligned with the connecting groove 221 for insertion. During the plugging process, the protective tube 12 can rotate automatically to align the limiting boss 14 with the connecting groove 221, thereby achieving a one-time successful plugging without the need for multiple alignments, and is easy to use.

[0041] Reference Figure 1 、 Figure 3 and Figure 4 The lower surface of the self-locking piece 3 facing the end of the socket 1 is provided with a self-locking block 31 that cooperates with the limiting boss 14. The end of the self-locking piece 3 away from the self-locking block 31 is an unlocking end 32. The two sides of the self-locking piece 3 are fixedly connected to the plug 2 through connecting support blocks 33. The self-locking piece 3 can be deflected around the connecting support block 33.

[0042] Reference Figure 1 、 Figure 3 and Figure 4The self-locking block 31 has an insertion bevel 311 on the side facing the socket 1 that mates with the interference bevel 141. The self-locking block 31 has a locking surface 312 on the side facing away from the socket 1 that mates with the engaging surface 142. During the plug 2 and socket 1 insertion process, the interference bevel 141 on the limiting boss 14 contacts the insertion bevel 311 of the self-locking block 31. As the limiting boss 14 advances, the self-locking block 31 is gradually lifted, and the self-locking plate 3 deflects around the connecting support block 33 until the self-locking block 31 passes over the interference bevel 141 and mates with the upper surface of the limiting boss 14. As the limiting boss 14 continues to advance, the self-locking block 31 passes over the limiting boss 14. The self-locking plate 3 returns to its original position and moves downward under its own elastic force, and the self-locking block 31 is locked into the engaging surface 142 of the limiting boss 14. At this time, the locking surface 312 contacts the engaging surface 142 , thereby limiting the limiting boss 14 and achieving self-locking of the plug 2 and the socket 1 .

[0043] Reference Figure 4 and Figure 5 An unlocking gap 24 is defined between the upper surface of the self-locking plate 3 and the socket 1. An unlocking tongue 4 is movably connected within this gap. Made of a material such as plastic, the unlocking tongue 4 exhibits a certain degree of toughness and elastic deformation. The unlocking tongue 4 includes a pressing end 41, distal from the self-locking block 31, and positioned above the unlocking end 32. When an operator depresses the pressing end 41, it applies downward pressure to the unlocking end 32, causing the self-locking plate 3 to pivot about the connecting support block 33, raising the end of the self-locking plate 3 with respect to the self-locking block 31.

[0044] Reference Figure 1 and Figure 3 A strip-shaped sliding groove 34 is provided in the middle of the self-locking piece 3, the self-locking block 31 is located at the end of the sliding groove 34 facing the socket 1, and the unlocking tongue 4 is fixed with a slider 42 that is slidably connected to the sliding groove 34. The unlocking tongue 4 is slidably connected to the self-locking piece 3 through the slider 42 and the sliding groove 34.

[0045] Reference Figures 3 to 5 A stopper 43 is fixed to the lower surface of the unlocking tongue 4, facing the side of the connecting support block 33. An unlocking groove 44 is formed on the lower surface of the unlocking tongue 4 to cooperate with the self-locking piece 3. When the unlocking tongue 4 moves to the extreme position toward the self-locking block 31, the self-locking piece 3 abuts against the end of the unlocking groove 44. When the unlocking tongue 4 moves to the extreme position away from the self-locking block 31, the stopper 43 abuts against the connecting support block 33.

[0046] Reference Figures 3 to 5The lower surface of the pressing end 41 is fixed with an anti-touch block 45 located on the outside of the self-locking piece 3, and the plug 2 is fixed with an anti-touch boss 25 facing the unlocking tongue 4. When the self-locking piece 3 collides with the end of the unlocking groove 44 away from the socket 1, the anti-touch block 45 is directly opposite to the anti-touch boss 25. When the plug 2 and the socket 1 are plugged in and connected for charging, the operator pushes the unlocking tongue 4 to slide in the direction of the self-locking block 31 until the self-locking piece 3 collides with the unlocking groove 44. At this time, the unlocking tongue 4 cannot be pushed further, and the anti-touch block 45 is directly opposite to the anti-touch boss 25. The anti-touch boss 25 restricts the unlocking tongue 4, and the operator cannot press down the pressing end 41, thereby preventing other people from accidentally touching the unlocking tongue 4 and causing unlocking, causing the plug 2 and the socket 1 to loosen.

[0047] Reference Figures 3 to 5 The end of the slider 42 away from the pressing end 41 is provided with a self-locking end. The lower surface of the self-locking end is provided with a curved anti-touch ball 421. The upper surface of the end of the self-locking block 31 facing the sliding groove 34 is provided with an anti-touch slope 313 that mates with the anti-touch ball 421. When the self-locking plate 3 contacts the end of the unlocking groove 44 away from the socket 1, the anti-touch ball 421 contacts the side of the self-locking block 31 facing away from the sliding groove 34. The lower surface of the slider 42 is provided with a lifting protrusion 46 that mates with the limiting boss 14. The side of the lifting protrusion 46 facing the self-locking block 31 is provided with a lifting slope 461 that mates with the interfering slope 141. When the plug 2 and the socket 1 are plugged together, the operator pushes the unlocking tongue 4 toward the self-locking block 31. During this push, the anti-touch ball 421 contacts the anti-touch slope 313 and slides along the anti-touch slope 313 to above the self-locking block 31. As the unlocking tongue 4 continues to be pushed until the self-locking plate 3 collides with the bottom of the unlocking groove 44, the anti-touch ball 421 passes over the upper surface of the self-locking block 31 and collides with the end face of the self-locking block 31. At this time, the unlocking tongue 4 is restricted by the anti-touch ball 421 and the self-locking block 31, preventing the unlocking tongue 4 from sliding backward on its own and causing unlocking.

[0048] The operating principle of the energy storage connector of the present embodiment is as follows: When plug 2 and socket 1 are plugged together, the operator holds plug 2 toward socket 1 and inserts the plug. The protective tube 12 rotates automatically, and the limiting boss 14 aligns with the connecting groove 221, gradually inserting the plug 2 into the socket 1. During the plugging process, the limiting boss 14 gradually inserts into the connecting groove 221. The limiting boss 14 first contacts the self-locking block 31, which lifts the self-locking block 31, causing the self-locking plate 3 to deflect. The limiting boss 14 continues to move for a certain period of time, then contacts the lifting protrusion 46, which lifts the lifting protrusion 46, thereby ejecting the end of the slider 42 from the sliding groove 34. When the plug 2 and socket 1 are fully plugged together, the limiting boss 14 passes over the self-locking block 31, and the locking surface 312 contacts the engaging surface 142, thereby restricting the limiting boss 14 and achieving self-locking between the plug 2 and socket 1.

[0049] The operator then pushes the unlocking tongue 4 toward the self-locking block 31 until the anti-touch ball 421 passes over the self-locking block 31 and the anti-touch block 45 directly contacts the anti-touch boss 25. At this point, the unlocking tongue 4 is limited and cannot be pressed down, thereby failing to achieve unlocking.

[0050] When the operator needs to unlock the plug 2 and the socket 1, he first pulls the unlocking tongue 4 backward, causing it to move away from the self-locking block 31 until the anti-touch ball 421 passes over the end of the self-locking block 31. At this time, the anti-touch block 45 is misaligned with the anti-touch boss 25. The operator presses down on the pressing end 41, which applies downward pressure to the unlocking end 32. The self-locking piece 3 deflects around the connecting support block 33, and the self-locking block 31 is lifted and separated from the limiting boss 14. The plug 2 and the socket 1 are unlocked, and the plug 2 can be separated from the socket 1.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
