Description

Technical Field

[0001] This application relates to the technical field of electrical connection devices, and more particularly to a connector. Background Technology

[0002] In the existing technology field, connectors, as a key electrical connection component, are widely used in various devices such as power distribution unit modules and energy storage transmission, undertaking the important task of current transmission. Their rated current carrying capacity ranges from 20 to 60A, providing a convenient and efficient solution for the electrical connection of equipment.

[0003] Most common connectors consist primarily of a plug and a socket that can be inserted into each other; that is, a first connector and a second connector are inserted into each other. After the plug and socket are inserted, a locking mechanism is used to lock them in place. This ensures that the plug and socket will not separate due to unforeseen circumstances during use, thereby preventing safety accidents caused by connection interruption and ensuring the stability and safety of equipment operation.

[0004] However, in real-world applications, connectors often require frequent plugging and unplugging operations. This high-frequency use easily causes wear on the locking components and also increases the possibility of operator misoperation when locking the components. Once the locking components are misoperated or fail to lock due to wear, the plug and socket are prone to separation. This not only prevents the connector from functioning properly for current transmission, causing equipment interruption, but more importantly, it significantly reduces the safety of the entire electrical system, posing a potential threat to the stable operation of the equipment and the personal safety of the operators.

[0048] Unless otherwise stated or defined, the term "and / or" as used in this invention includes any and all combinations of one or more of the associated listed items.

[0049] For ease of description, the vertical direction mentioned below is the same as... Figure 1 Its vertical direction is consistent with the horizontal direction mentioned below. Figure 1 Its left and right directions are consistent.

[0050] like Figures 1 to 7As shown, this embodiment provides a connector, including a first connector 11, a second connector 12, a locking member 13, and an anti-unlocking member 14. One of the first connector 11 and the second connector 12 is a socket, and the other is a plug. In this embodiment, the first connector 11 is used as a plug and the second connector 12 as a socket. The second connector 12 is inserted into the first connector 11, achieving an electrical connection between the second connector 12 and the first connector 11.

[0051] The first connecting seat 11 is provided with an anti-detachment part 111, which is a boss provided on the outer surface of the first connecting seat 11. The anti-detachment part 111 is integrally formed with the first connecting seat 11, and multiple bosses are provided and spaced apart.

[0052] The locking member 13 is pivotally mounted on the first connecting seat 11 to switch between a locked state (locking the first connecting seat 11 and the second connecting seat 12) and an unlocked state (releasing the lock on the first connecting seat 11 and the second connecting seat 12). The locking member 13 can switch between the locked and unlocked states when it pivots relative to the first connecting seat 11. When the end of the locking member 13 near the second connecting seat 12 pivots downwards towards the second connecting seat 12, the locking member 13 engages or latches with the second connecting seat 12, locking the first connecting seat 11 and the second connecting seat 12, preventing them from sliding relative to each other. When the end of the locking member 13 near the second connecting seat 12 pivots upwards away from the second connecting seat 12, the locking member 13 and the second connecting seat 12 can slide relative to each other, achieving separation.

[0053] Thus, when the locking member 13 is in the locked state, it locks the first connecting seat 11 and the second connecting seat 12, preventing them from separating and thus achieving electrical connection of the connector. When the locking member 13 is in the unlocked state, it releases the locking of the first connecting seat 11 and the second connecting seat 12, allowing them to slide relative to each other and separate, thereby disconnecting the electrical connection of the connector.

[0054] The anti-unlocking component 14 is slidably mounted on the first connecting seat 11 to switch between a free position and a restricted position. The anti-unlocking component 14 is slidably mounted on the first connecting seat 11 along a straight path, so that the anti-unlocking component 14 can switch between a free position and a restricted position.

[0055] When the anti-unlocking component 14 is in the restricted position, it is located on the downward swing path of the locking component 13, thereby restricting the locking component 13 from switching from the locked state to the unlocked state and preventing the locking component 13 from failing to lock due to misoperation or other reasons during use. When the anti-unlocking component 14 is in the free position, it is away from the downward swing path of the locking component 13, allowing the locking component 13 to swing downward and release the engagement or latching between the locking component 13 and the second connecting seat 12.

[0056] The anti-detachment part 111 is located on the sliding path of the anti-unlocking member 14 to prevent the anti-unlocking member 14 from separating from the first connecting seat 11. When the anti-unlocking member 14 is pushed to the right, the locking member 13 is locked and cannot swing, thus locking the first connecting seat 11 and the second connecting seat 12. When the anti-unlocking member 14 slides to the left to reach the free position, the locking member 13 can swing up and down. The left end of the anti-unlocking member 14 abuts against the anti-detachment part 111 or is fastened to the anti-detachment groove of the anti-detachment part 111 to prevent the anti-unlocking member 14 from falling off the first connecting seat 11, making it easier to push the anti-unlocking member 14 to slide to the restricted position next time, so that the first connecting seat 11 and the second connecting seat 12 can be tightly connected.

[0057] In one embodiment, the locking member 13 is arranged parallel to the second connecting seat 12 and has a locking end 131. The locking end 131 is located at the end of the locking member 13 near the second connecting seat 12. When the end of the locking member 13 away from the second connecting seat 12 is pressed, the locking end 131 moves upward. A latch 132 is provided on the lower end surface of the locking end 131. The latch 132 is a barb. The second connecting seat 12 is provided with a locking platform 121, which is a right-angled triangular body or a right-angled trapezoid. The cross-section of the locking platform 121 gradually increases in the direction away from the first connecting seat 11. In this way, the barb can move to the right side of the locking platform 121 along the inclined surface of the locking platform 121. Without the action of external force, the locking end 131 of the locking member 13 moves downward to switch to the locked state by elasticity or moves downward to switch to the locked state by the push of the anti-unlocking member 14. The vertical surface on the right side of the locking platform 121 restricts the leftward movement of the latch 132, thereby preventing the second connecting seat 12 from separating from the first connecting seat 11.

[0058] When the locking member 13 is in the locked state, the vertical surface on the right side of the locking platform 121 is located on the movement path of the latch 132, so as to restrict the separation of the first connecting seat 11 and the second connecting seat 12. If you want to separate the first connecting seat 11 and the second connecting seat 12, first push the anti-unlocking member 14 to slide to the free position, and then press the end of the locking member 13 away from the second connecting seat 12 so that the locking end 131 moves upward. At this time, the movement of the locking member 13 away from the second connecting seat 12 will not be restricted by the vertical surface on the right side of the locking platform 121, thereby releasing the locking member 13 from the second connecting seat 12.

[0059] Furthermore, the locking member 13 also has a pressing end 133 and a supporting end 134 connected to the first connecting seat 11. The pressing end 133 is located at the end of the locking member 13 away from the second connecting seat 12. The supporting end 134 is located between the pressing end 133 and the locking end 131. The supporting end 134 is integrally formed with the connecting seat and has elasticity that allows it to automatically recover its deformation. When the supporting end 134 returns to its initial state without external force, the locking member 13 is in a locked state. The pressing end 133 and the locking end 131 swing relative to each other in opposite directions around the supporting end 134. That is, when the pressing end 133 swings upward, the locking end 131 swings downward, and when the pressing end 133 swings downward, the locking end 131 swings upward. The pressing end 133 forms a sliding gap 19 with the first connecting seat 11, and the right end of the anti-unlocking member 14 can slide into the sliding gap 19.

[0060] When the anti-unlocking component 14 is in the restricted position, at least a portion of the anti-unlocking component 14 is located within the sliding gap 19 and clamped between the pressing end 133 and the first connecting seat 11. The upper end surface of the pressing end 133 is provided with pressing anti-slip texture, and the lower end surface of the pressing end 133 abuts against the anti-unlocking component 14, preventing the pressing end 133 from being pressed downward, and the latch 132 engages with the locking platform 121. When the anti-unlocking component 14 is in the free position, the anti-unlocking component 14 is located outside the sliding gap 19, the pressing end 133 can be pressed downward, and the latch 132 separates from the locking platform 121.

[0061] Optionally, the first connecting seat 11 is provided with a guide groove 151. The anti-unlocking member 14 is slidably disposed in the guide groove 151, and the anti-detachment part 111 is located on the movement path of the anti-unlocking member 14 when it switches from the restricted position to the free position. When the anti-unlocking member 14 is in the free position, one end of the anti-unlocking member 14 is located in the guide groove 151, and the other end of the anti-unlocking member 14 abuts against the anti-detachment part 111. Specifically, the first connecting seat 11 is integrally formed with a guide seat 15. There are two guide seats 15 arranged at intervals. Both guide seats 15 have guide grooves 151. The anti-unlocking member 14 is located between the two guide seats 15, and both sides of the anti-unlocking member 14 are slidably disposed in the guide grooves 151 of the two guide seats 15. When the anti-unlocking component 14 switches from the restricted position to the free position, the right end of the anti-unlocking component 14 falls off the sliding gap 19 but still slides in the guide groove 151, and the left end of the anti-unlocking component 14 abuts against the anti-detachment part 111, thereby preventing the anti-unlocking component 14 from continuing to slide to the left and detaching from the guide groove 151, and avoiding the anti-unlocking component 14 from detaching from the first connecting seat 11.

[0062] In one embodiment, the first connecting seat 11 has a plug-in portion 112, and a sealing ring is sleeved on the plug-in portion 112, with the sealing ring surrounding the plug-in portion 112. The second connecting seat 12 has a plug-in groove 122, and the plug-in portion 112 is inserted into the plug-in groove 122 to realize the plug-in connection between the first connecting seat 11 and the second connecting seat 12. The sealing ring is clamped between the plug-in portion 112 and the inner wall of the plug-in groove 122 to achieve a seal.

[0063] Optionally, the insertion part 112 is provided with a sealing groove 113, and at least part of the sealing ring is engaged in the sealing groove 113 to achieve the positioning and installation of the sealing ring.

[0064] Furthermore, the second connecting seat 12 is provided with a connecting flange 20, which is a square annular ring surrounding the second connecting seat 12 and is integrally formed with the second connecting seat 12. The connecting flange 20 has an annular groove 201, which is a square annular ring. A sealing gasket 16 is provided within the annular groove 201 to prevent the sealing gasket 16 from being easily squeezed out during the installation of the second connecting seat 12, thus ensuring a proper seal. The sealing gasket 16 is square annular. The connecting flange 20 is used for installation in locations such as chassis where sockets need to be installed. During the installation of the second connecting seat 12, the connecting flange 20 is installed in the chassis using bolts, etc. The sealing gasket 16 is clamped between the connecting flange 20 and the chassis to achieve a seal, improving the structural robustness and waterproofing of the second connecting seat 12 during installation.

[0065] In one embodiment, the connector further includes a first terminal 17 mounted on a first connector 11 and a second terminal 18 mounted on a second connector 12. Multiple first terminals 17 are spaced apart, and multiple second terminals 18 are spaced apart. Each first terminal 17 has a first insertion end 171 for insertion into the second terminal 18 and a first connection end 172 for connection with a wire. A first limiting platform 173 and a second positioning platform 174 are spaced apart and arranged in a ring between the first insertion end 171 and the first connection end 172. The first connector 11 has a first terminal hole 114, into which the first terminal 17 is inserted. The first limiting platform 173 is closer to the first connection end 172 than the second limiting platform. The diameter of the second positioning platform 174 gradually decreases along the direction away from the first limiting platform 173. The second positioning platform 174 is in the shape of a right-angled triangular or right-angled trapezoid, facilitating the insertion of the first terminal 17 into the first terminal hole 114.

[0066] The inner wall of the first terminal hole 114 is provided with a plurality of positioning claws 115 arranged circumferentially along the first terminal 17. The positioning claws 115 are integrally formed with the first connecting seat 11. Each positioning claw 115 is located between the first limiting platform 173 and the second positioning platform 174. One end of each positioning claw 115 is connected to the inner wall of the first terminal hole 114, and the other end of each positioning claw 115 extends along the direction close to the second positioning platform 174, and the distance between each positioning claw 115 gradually decreases. When the first terminal 17 is inserted into the first terminal hole 114, the second positioning platform 174 passes between the positioning claws 115. Under the guidance of the inclined surface of the second positioning platform 174, the positioning claws 115 undergo elastic deformation, which increases the distance between the positioning claws 115. After the second positioning platform 174 passes through the area between the positioning claws 115, the positioning claws 115 restore their deformation, and the ends of the positioning claws 115 abut against the vertical surface of the second positioning platform 174. The first terminal 17 is prevented from dislodging from the first terminal hole 114 by the limiting of the first limiting platform 173 and the second positioning platform 174.

[0067] The first connector 11 is made of plastic. In this application, the first connector 11 and the positioning claw 115 are integrally molded through injection molding. Compared with the traditional connectors that use metal positioning claws 115 for separate installation, this application can reduce the complexity of the assembly process and the assembly cost. Therefore, the first connector 11 has its own positioning claw 115 to fix the first terminal 17, which not only reduces the cost but also makes the structure stable.

[0068] Furthermore, the first connector 11 is also provided with a wiring hole 116 communicating with the first terminal hole 114. A sealing body 117 is provided inside the wiring hole 116. The wire passes through the wiring hole 116 and is connected to the first connection end 172 of the first terminal 17. The sealing body 117 improves the sealing performance of the wiring hole 116 and seals the gap between the wire and the inner wall of the wiring hole 116.

[0069] Optionally, the second connector 12 is injection molded onto the second terminal 18. The second terminal 18 has a second insertion end 181 that inserts into the first terminal 17 and a second connection end 182 for connecting to a wire. The second connection end 182 is located outside the second connector 12 for connecting external wires. The first insertion end 171 is a pin, and the second insertion end 181 is a socket for inserting the pin. In order to make the second terminal 18 and the second connector 12 an integral structure, the second terminal 18 is placed in a mold, and then the second connector 12 is formed on the second terminal 18 by injection molding, so that the second terminal 18 and the second connector 12 fit together tightly without gaps. This connection method has a strong structure and good sealing performance. The injection-molded second connector 12 has a second terminal hole 123, and the second insertion end 181 is inserted into the second terminal hole 123.

[0070] The technical principles of this application have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this application and should not be construed as limiting the scope of protection of this application in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this application without inventive effort, and these embodiments will all fall within the scope of protection of this application.
