Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a plastic connector unlocking structure. Background Technology

[0002] Automotive high-voltage connectors are electrical connection devices specifically designed for use in new energy vehicles such as electric vehicles (EVs) and hybrid electric vehicles (HEVs). They are mainly used in high-voltage power systems to connect high-voltage batteries to motors, charging equipment, and other electrical components. Their main function is to ensure the safe and reliable transmission of electrical energy under high voltage and high current conditions, ensuring the normal operation of the vehicle under various environmental conditions.

[0003] Existing single-axis push-button connectors typically use a press-and-rotate mechanism to achieve mating and removal. The specific working principle is as follows: During connector insertion, the plug is pushed axially to insert it into the socket. The connection is then locked by pressing the locking button on the connector or rotating the plug. To unlock, pressing or rotating again releases the connector locking mechanism, allowing the plug to be removed from the socket.

[0004] The existing technology has the following drawbacks: In the existing single-axis push-button connector, pressing down on the press plate 3 causes it to rotate along the connecting shaft 2 to unlock the connector. Only one set of connecting shafts 2 is provided between the press plate 3 and a set of walls of the housing 1. In order to ensure the normal rotation of the press plate 3, only one set of connecting shafts 2 can be provided, which makes the connection between the press plate 3 and the housing 1 relatively weak. Moreover, since the plug and locking mechanism are usually made of plastic materials, repeated pressing and unlocking will cause material fatigue, which will reduce the resilience of the connector. After repeated insertion and removal, the locking function may weaken, increasing the risk of loose connection and accidental unlocking, thus affecting the overall safety and reliability of the connector. Therefore, there is room for improvement. Utility Model Content

[0005] The purpose of this utility model is to provide a plastic connector unlocking structure to solve the technical problem that existing high-voltage connectors are made of plastic materials and use a single-axis pressing method for locking. The more times they are pressed, the weaker the rebound performance of the connector becomes. Repeated pressing can easily lead to unstable connector connection and accidental contact.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] A plastic connector unlocking structure includes a plug assembly, a socket assembly, and an unlocking component. The socket assembly includes a support base and a pressing plate. The socket assembly has a connection cavity. The support base is disposed on the bottom surface of the connection cavity. Multiple sets of support bases are provided. The middle part of the pressing plate is elastically connected to the support base. The pressing plate is engaged with the plug assembly. The unlocking component is detachably installed in the connection cavity.

[0008] Optionally, the connecting cavity is provided with a locking plate on both sides, and the unlocking component includes an insert block and a guide block. The guide block is disposed on both sides of the insert block and the guide block is shaped to match the locking plate.

[0009] Optionally, the card plate is provided with a first sliding groove, the first sliding groove is provided along a first direction, and a first limiting block is provided on the opposite end faces of the guide blocks. The first limiting block slides in the first sliding groove and is used to limit the displacement of the unlocking component in a second direction.

[0010] Optionally, the unlocking component further includes a rod fixed to the plug block, the rod having a stepped portion, and the bottom surface of the connecting cavity having an abutment groove, the stepped portion abutting against the abutment groove to limit the displacement of the unlocking component in a first direction.

[0011] Optionally, the end of the plug rod is provided with a lifting part, the bottom surface of the lifting part is inclined, and from the horizontal direction, the bottom surface of the lifting part is inclined upward along a first direction. The plug assembly includes a housing, the plug terminal is disposed in the housing, and the housing is inserted into the bottom surface of the lifting part.

[0012] Optionally, the bottom surface of the insert block is provided with a second sliding groove, the second sliding groove is provided with a second limiting block, and the bottom surface of the connecting cavity is provided with an anti-retraction protrusion, which is slidably disposed in the second sliding groove.

[0013] Optionally, the top surface of the housing is provided with a protrusion, and the pressing plate includes a fastening part and a pressing part, the fastening part being fastened to the protrusion, and the pressing part being used to rotate the fastening part.

[0014] Optionally, when viewed from the horizontal direction, the top surface of the protrusion is inclined downward along the second direction.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention features multiple sets of support seats on the bottom surface of the connecting cavity, enabling a single contact surface to correspond to multiple rotation points. When the pressing plate is pressed down, the multiple support points work together to provide a rebound force, allowing it to quickly return to its original position. Simultaneously, the multiple sets of support seats are distributed below the center of the pressing plate, ensuring more even force distribution and preventing prolonged pressure on any single point. This effectively prevents the plastic from cracking or permanently deforming due to fatigue, thus improving the connector's lifespan. The unlocking component is detachably installed within the connecting cavity. When locked, the unlocking component is inserted into the connecting cavity, restricting the pressing plate's downward movement and preventing accidental pressing, which in turn prevents the plug from separating from the socket. When unlocked, the unlocking component is removed, releasing the restriction on the pressing plate and preventing accidental locking due to external impacts, misoperation, vibration, etc., thus improving the connection stability of the connector structure.

[0031] The connector unlocking structure provided in this embodiment is applied to the scenario of electrical connection equipment. By improving the connector unlocking structure in this embodiment, the connector structure still has good resilience performance after multiple unlockings. At the same time, it avoids the connector from being unlocked due to accidental contact, thereby improving the connection stability of the connector structure.

[0032] Please see Figures 1-6 The plastic connector unlocking structure provided in this embodiment includes a plug assembly 10, a socket assembly 20, and an unlocking component 30. The socket assembly 20 includes a support base 210 and a pressing plate 220. A connecting cavity 230 is provided on the socket assembly 20. The support base 210 is disposed on the bottom surface of the connecting cavity 230, and multiple sets of support bases 210 are provided. The middle part of the pressing plate 220 is elastically connected to the support base 210. The pressing plate 220 is engaged with the plug assembly 10. The unlocking component 30 is detachably installed in the connecting cavity 230. Specifically, the support base 210 is configured as an elastic support base 210. When locked, the plug assembly 10 and the socket assembly 20 are engaged, and at the same time, the unlocking component 30 is inserted into the connecting cavity 230. When unlocked, the unlocking component 30 is removed, and one end of the pressing plate 220 is pressed down to rotate the pressing plate 220, thus separating the plug assembly 10 from the socket assembly 20. By setting multiple sets of support seats 210 on the bottom surface of the connecting cavity 230, a setting of multiple rotation points corresponding to one contact surface is realized. After the pressing plate 220 is pressed, multiple support points work together to provide a rebound force, so that it quickly returns to its original position. At the same time, the multiple sets of support seats 210 are distributed in the lower middle part of the pressing plate 220, so that the force is more evenly distributed, avoiding long-term pressure on a certain point, effectively preventing the plastic from breaking or permanently deforming due to fatigue, and improving the life of the connector. In addition, the multi-point support can form a multi-point rotation axis structure, making the pressing action more stable, less prone to deflection or jamming, and improving the user's operating feel.

[0033] The unlocking component 30 is detachably installed in the connecting cavity 230. When locked, the unlocking component 30 is inserted into the connecting cavity 230, restricting the downward movement of the pressing plate 220, thereby preventing the pressing plate 220 from being accidentally pressed down and thus preventing the plug and socket from separating. When unlocking, the unlocking component 30 is removed, releasing the restriction on the pressing plate 220. At this time, the user presses down on one end of the pressing plate 220 to make it rotate, unlocking the plug assembly 10 and the socket assembly 20, thus separating the plug assembly 10 and the socket assembly 20. After the unlocking component 30 is inserted, it forms a physical block on the pressing plate 220, preventing the pressing plate 220 from being accidentally pressed down due to external force collision, misoperation, vibration, etc., thus preventing accidental locking. Removing the unlocking component 30 and pressing down the pressing plate 220 will disconnect the plug. The installation and removal of the unlocking component 30 are intuitive and easy to operate, improving the user experience of the product.

[0034] Furthermore, locking plates 240 are provided on both sides of the connecting cavity 230. The unlocking component 30 includes an insertion block 310 and a guide block 320. The guide block 320 is located on both sides of the insertion block 310 and its shape matches that of the locking plate 240. Specifically, the unlocking component 30 can only slide along the inner side of the locking plate 240 during insertion and removal, preventing the unlocking component 30 from deflecting, skewing, or getting stuck during insertion. This ensures smooth, stable, and reliable insertion, and improves the assembly alignment accuracy between the unlocking component 30 and the connecting cavity 230. At the same time, after the unlocking component 30 is inserted, it can accurately cover the bottom area of ​​the pressing plate 220, completely restricting the pressing plate 220 and improving the anti-accidental touch effect of the pressing plate 220.

[0035] Furthermore, the card plate 240 is provided with a first sliding groove 241, which is arranged along a first direction. A first limiting block 321 is provided on the opposite end faces of the guide blocks 320. The first limiting block 321 slides within the first sliding groove 241 and is used to limit the displacement of the unlocking component 30 in a second direction. Specifically, when the first limiting block 321 slides on the first sliding groove 241, the unlocking component 30 is unlikely to detach from the socket assembly 20 in the second direction under the influence of small forces such as vibration or collision, thus ensuring the installation stability of the unlocking component 30.

[0036] Furthermore, the unlocking component 30 also includes a rod 330, which is fixed to the plug block 310. The rod 330 is provided with a stepped portion 331, and the bottom surface of the connecting cavity 230 is provided with an abutment groove 231. The stepped portion 331 abuts against the abutment groove 231 to limit the displacement of the unlocking component 30 in the first direction. Specifically, in the first state, the unlocking component 30 cooperates with the socket component 20, and the guide block 320 slides along the card plate 240, so that the unlocking component 30 is inserted into the connecting cavity 230 until the first limiting block 321 slides to the first sliding groove 241. The first sliding groove 241 restricts the displacement of the unlocking component 30 in the second direction. At the same time, the stepped portion 331 abuts against the abutting groove 231. The setting of the abutting groove 231 restricts the displacement of the unlocking component 30 in the first direction. The setting of the first sliding groove 241 and the abutting groove 231 restricts the displacement of the unlocking component 30 on the socket component 20. The unlocking component 30 and the socket component 20 do not produce relative displacement, which provides an installation basis for cooperation with the plug component 10.

[0037] Furthermore, the end of the plug rod 330 is provided with a lifting portion 332, the bottom surface of the lifting portion 332 is inclined, and viewed from the horizontal direction, the bottom surface of the lifting portion 332 is inclined upward along the first direction. The plug assembly 10 includes a housing 110, the plug terminal is disposed in the housing 110, and the housing 110 is inserted into the bottom surface of the lifting portion 332. Specifically, in the second state, the plug assembly 10 cooperates with the socket assembly 20. During the insertion process of the housing and the socket assembly 20, since the bottom surface of the lifting portion 332 is inclined upward along the first direction, the housing is inserted into the bottom surface of the lifting portion 332. In the third state, the housing is inserted into the bottom surface of the lifting portion 332, causing the end of the plug rod 330 to be lifted upward. During the lifting process of the end of the plug rod 330, the locking action between the stepped portion 331 and the abutment groove 231 is released, and the unlocking component 30 continues to slide along the first direction within the connecting cavity 230. By inserting the outer shell into the bottom surface of the lifting part 332, the lifting part 332 is raised, and the unlocking component 30 is moved further. After the unlocking component 30 moves further, it achieves a tight fixation against the surface of the outer shell, so that the unlocking component 30 needs to overcome greater resistance to slide out of the connecting cavity 230, ensuring the installation stability of the unlocking component 30. At the same time, the further movement of the unlocking component 30 causes the unlocking component 30 to engage at the connection position between the support base 210 and the pressing plate 220, further reducing the range of motion of the pressing plate 220 in the locked state, reducing the rotation of the pressing plate 220 due to external pressure, and further reducing the elastic fatigue loss of the pressing plate 220 due to external force. Moreover, due to the further movement of the unlocking component 30, the contact area between the plug 330 and the outer shell increases, and the plug assembly 10 needs to overcome greater friction to separate from the socket assembly 20, further ensuring the connection stability when the connector structure is locked.

[0038] Furthermore, the bottom surface of the plug 310 is provided with a second sliding groove 311, and a second limiting block 312 is provided within the second sliding groove 311. The bottom surface of the connecting cavity 230 is provided with an anti-retraction protrusion 232, which is slidably disposed within the second sliding groove 311. Specifically, in the fourth state, as the unlocking component 30 continues to slide along the first direction within the connecting cavity 230, the second limiting block 312 engages with the anti-retraction protrusion 232, thus restricting the displacement of the unlocking component 30 in the second direction. At this time, the plug assembly 10 and the socket assembly 20 complete the mating action. By limiting the displacement of the unlocking component 30 in the second direction through the setting of the anti-retraction protrusion 232, the installation stability of the unlocking component 30 is further improved.

[0039] Furthermore, the top surface of the housing 110 is provided with a protrusion 111, and the pressing plate 220 includes a fastening part 221 and a pressing part 222. The fastening part 221 is fastened to the protrusion 111, and the pressing part 222 is used to rotate the fastening part 221. Specifically, when unlocking is required, after removing the unlocking component 30, a downward force is applied to the pressing part 222. The support base 210 serves as a fulcrum, and the fastening part 221 rotates upward, thereby releasing the fastening relationship between the protrusion 111 and the fastening part 221, realizing the unlocking action of the plug assembly 10 and the socket assembly 20, and ensuring the ease of disassembly of the connector structure.

[0040] Furthermore, viewed horizontally, the top surface of the protrusion 111 is inclined downwards along the second direction. Specifically, the inclined top surface of the protrusion 111 allows the fastening part 221 to slide upwards along the inclined top surface when it engages with the protrusion 111, until the fastening part 221 and the protrusion 111 complete the fastening action, ensuring the smoothness of the fastening process and the stability of the fastening effect.

[0041] In summary, the connector unlocking structure provided in this embodiment has advantages such as good rebound performance, prevention of accidental contact, and high connection stability.
