Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a socket and connector. Background Technology

[0002] Connector Position Assurance (CPA) in power connectors is a design feature used to ensure the stability and reliability of the connector plug and socket in the connected state. CPA structures typically include additional mechanical locking or snap-fit ​​mechanisms as an auxiliary to the connector's primary locking structure (such as snap-fit ​​or push-pull locking). Once the connector's primary locking structure is locked, the CPA structure further reinforces the connection, preventing the connector from accidentally disconnecting due to vibration, impact, or other dynamic forces.

[0003] However, in some existing power connectors, the main locking structure may fail to lock properly for some reason, while the secondary locking operation of the CPA structure will still be performed, leading users to mistakenly believe that the connector is securely locked. However, in actual use, such insufficiently locked connectors are very prone to accidental disconnection due to vibration, impact, or other dynamic forces, causing electrical connection interruption and potentially even safety accidents.

[0036] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0037] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0038] Reference Figures 1 to 2 as well as Figure 5According to a first aspect of the present invention, the plug 2 is configured to be inserted into a socket 3. The plug 2 includes an insulating body 10, a locking pin 20, and a locking tab 30. The insulating body 10 is provided with a plug interface 11 and a slot 12. One end of the socket 3 is inserted into the plug interface 11, and the slot 12 communicates with the plug interface 11. The locking pin 20 is slidably disposed in the slot 12 and is elastically connected to the insulating body 10. The locking pin 20 is provided with a snap-fit ​​portion 21, which is located outside the first end of the locking pin 20 and is located in the plug interface 11. The snap-fit ​​portion 21 is configured to snap into the snap-fit ​​groove 4 of the socket 3 to prevent the plug 2 from coming loose from the socket 3. The locking tab 30 is slidably disposed in the sliding groove 13 of the insulating body 10. When the snap-fit ​​portion 21 snaps into the snap-fit ​​groove 4 of the socket 3, one end of the locking tab 30 is inserted into the second end of the locking pin 20.

[0039] The plug 2 of this invention, through its locking pin 20 and locking tab 30 structure, solves the locking connection failure problem that may occur in the existing CPA structure of the power connector 1. Specifically, the elastic connection between the locking pin 20 and the insulating body 10 ensures that the plug 2 can automatically achieve initial locking after being inserted into the socket 3. Its snap-fit ​​part 21 fits tightly with the snap-fit ​​groove 4 of the socket 3, effectively preventing the plug 2 from accidentally loosening due to vibration or impact. At the same time, the design of the locking tab 30 further enhances the locking reliability of the plug 2. Only when the snap-fit ​​part 21 is correctly snapped into the snap-fit ​​groove 4 of the socket 3 can the locking tab 30 slide to the second end of the locking pin 20 to form a secondary lock, thereby ensuring a stable connection between the plug 2 and the socket 3. This design not only improves the safety of the power connector 1 but also simplifies the unlocking process of the connector 1, allowing users to operate easily and accurately when unlocking is required, greatly improving the practicality and convenience of the connector 1.

[0040] Specifically, the plug 2 is configured to be inserted into a matching socket 3 to achieve stable power or signal transmission. The plug 2 comprises three main parts: an insulating body 10, a locking pin 20, and a locking clip 30. The insulating body 10 is the supporting structure of the plug 2, and it has a connector 11 and a slot 12. The connector 11 receives the insertion end of the socket 3, while the slot 12 communicates with the connector 11, for locking the locking pin 20's engaging portion 21 into the engaging groove 4 on the socket 3. The locking pin 20 is slidably disposed in the slot 12 and elastically connected to the insulating body 10 by a spring or other elastic element. A engaging portion 21 is provided on the outer side of the first end of the locking pin 20, which is located in the connector 11 and configured to engage into the engaging groove 4 of the socket 3. When plug 2 is inserted into socket 3, the locking part 21, under the pressure of the top of socket 3, first causes the locking pin 20 to store elastic potential energy. When plug 2 is fully inserted into socket 3, the locking part 21 slides into the locking groove 4 of socket 3. At this time, the locking pin 20 rebounds through elastic potential energy, and the locking part 21 automatically engages with the locking groove 4 under the action of elastic force, achieving initial locking of plug 2. The locking tab 30 can slide in the groove 13 of insulating body 10. When the locking part 21 is correctly engaged in the locking groove 4 of socket 3, one end of the locking tab 30 is inserted into the second end of locking pin 20 under the action of external force (such as manual pushing), forming secondary locking. In this way, even if plug 2 is subjected to vibration or impact, it can maintain a stable connection with socket 3, effectively preventing plug 2 from accidentally loosening.

[0041] Therefore, it is understood that the plug 2 according to the present utility model embodiment has at least the following beneficial effects: the insulating body 10 is inserted into the socket 3 through the plug interface 11, and the locking part 21 of the locking pin 20 can pass through the slot 12 and engage with the locking groove 4 on the socket 3 in the plug interface 11, thereby realizing the connection between the socket 3 and the plug 2; when the locking part 21 engages with the locking groove 4, the locking buckle 30 can be inserted into the second end of the locking pin 20, and the locking pin 20 is locked by the locking buckle 30 inserted into the locking pin 20, thereby realizing the secondary locking of the plug 2 and the socket 3.

[0042] Reference Figure 2 as well as Figures 4 to 5 In some embodiments of this utility model, the snap-fit ​​portion 21 gradually shifts toward the axis of the locking pin 20 along the direction from the first end to the second end of the locking pin 20, and the first end of the locking pin 20 is elastically connected to the interior of the insulating body 10.

[0043] In the plug 2 of this embodiment, the engaging portion 21 gradually shifts towards the axis of the locking pin 20 along the direction from the first end to the second end (from right to left in the figure). This design allows the engaging portion 21 to gradually align and engage with the engaging groove 4 of the socket 3 during the insertion of the locking pin 20. This facilitates the upper end of the socket 3 to press the locking pin 20, causing it to overcome its elasticity and move to the right, ultimately allowing the engaging portion 21 to engage in the engaging groove 4, thereby improving the smoothness of insertion and the reliability of locking. Simultaneously, the first end of the locking pin 20 is elastically connected to the interior of the insulating body 10 via elastic elements such as springs. This elastic connection not only ensures that the locking pin 20 automatically adapts to the position of the socket 3 when inserted, but also ensures that the engaging portion 21, after being connected in place, is stably engaged in the engaging groove 4, thus maintaining a tight fit with the engaging groove 4 and effectively preventing the plug 2 from coming loose from the socket 3.

[0044] Reference Figures 2 to 4 as well as Figures 6 to 7 In some embodiments of this utility model, the second end of the locking pin 20 is provided with a socket 22, and the locking buckle 30 includes a tongue 31, which can be slidably disposed in the slide groove 13. When the snap-fit ​​part 21 is snapped into the snap-fit ​​groove 4 of the socket 3, the tongue 31 can be inserted into the socket 22.

[0045] In this embodiment, the plug 2 further refines the structure of the locking pin 20 and the locking tab 30. Specifically, the second end of the locking pin 20 is provided with a socket 22, which is used to cooperate with the tongue 31 of the locking tab 30. The locking tab 30 includes a tongue 31 that can slide smoothly in the groove 13 of the insulating body 10. When the plug 2 is inserted into the socket 3 and the locking part 21 is correctly engaged in the locking groove 4 of the socket 3, the locking part 21 of the locking pin 20 is engaged in the locking groove 4, and the socket 22 on the second end of the locking pin 20 is directly below the tongue 31. Therefore, under the action of external force (such as manual pushing or using the natural force when the plug 2 is inserted into the socket 3), the tongue 31 of the locking tab 30 can be accurately inserted into the socket 22 of the locking pin 20. In this way, the cooperation between the tongue 31 and the socket 22 forms a secondary locking mechanism, which can prevent the locking pin 20 from being further inserted into the slot 12 and also prevent it from being pulled out by external force. Therefore, it can further enhance the connection stability between the plug 2 and the socket 3 and effectively prevent the plug 2 from being accidentally loosened due to external factors (such as vibration, impact, etc.).

[0046] Reference Figure 3 as well as Figures 6 to 7In some embodiments of this utility model, the groove walls on both sides of the slide groove 13 are provided with limiting blocks 131, and the locking buckle 30 also includes a limiting arm 32, which is slidably disposed in the slide groove 13 through the limiting block 131.

[0047] In this embodiment, the plug 2 further optimizes the structure of the slide groove 13 and the locking tab 30. Specifically, limit blocks 131 are provided on both sides of the slide groove 13, which limit the sliding path of the locking tab 30. In addition to the tongue 31 that can be inserted into the socket 22 of the locking pin 20, the locking tab 30 is also provided with a limiting arm 32. The design of the limiting arm 32 allows it to cooperate with the limiting blocks 131 on both sides of the slide groove 13, ensuring that the locking tab 30 will neither disengage from the slide groove 13 nor wobble in the slide groove 13 when sliding in the slide groove 13, thereby maintaining the stability and accuracy of the sliding of the locking tab 30. When plug 2 is inserted into socket 3 and the locking part 21 engages with the locking groove 4 of socket 3, the user can push the limiting arm 32 of locking tab 30, allowing it to slide smoothly to the locking position under the guidance of limiting block 131. At this time, tongue 31 can be inserted into the socket 22 of locking pin 20 along with the sliding of limiting arm 32, forming a stable secondary lock. This design not only improves the locking reliability of plug 2, but also makes the structure of plug 2 more compact and safer and more reliable to use.

[0048] Reference Figure 3 as well as Figures 6 to 7 In some embodiments of this utility model, a first protrusion 321 is provided at one end of the limiting arm 32. The first protrusion 321 is located on the side of the limiting block 131 near the locking pin 20, and the first protrusion 321 is configured to engage with the side of the limiting block 131.

[0049] The plug 2 of this embodiment further optimizes the limiting arm 32 of the locking tab 30 in the above embodiment. Specifically, one end of the limiting arm 32 is provided with a first protrusion 321, which is located on the side of the limiting block 131 near the locking pin 20 (i.e., the lower side of the limiting block 131 in the figure). When the locking tab 30 slides in the slide groove 13, the first protrusion 321 contacts one side of the limiting block 131 (the lower side of the limiting block 131 in the figure) and acts as a latch. This latching design not only ensures the stability of the locking tab 30 during the sliding process, but also prevents the locking tab 30 from easily disengaging from the slide groove 13 or causing unnecessary shaking when subjected to external force. During the process of inserting the plug 2 into the socket 3 and locking it, when the user pushes the locking clip 30 downwards, the first protrusion 321 cooperates with the limiting block 131, allowing the locking clip 30 to slide accurately to the locked position. At this time, the tongue 31 is firmly inserted into the socket 22 of the locking pin 20. When unlocking is required, the user only needs to push the locking clip 30 in the opposite direction (upwards). The first protrusion 321 will cooperate with the limiting block 131 again, and the first protrusion 321 will abut against the lower side of the limiting block 131, guiding the locking clip 30 to slide smoothly out of the locked position.

[0050] Similarly, refer to Figure 3 as well as Figures 6 to 7 In some embodiments of this utility model, the other end of the limiting arm 32 is provided with a second protrusion 322. The second protrusion 322 is located on the side of the limiting block 131 away from the locking pin 20, and the second protrusion 322 is configured to engage with the other side of the limiting block 131.

[0051] In this embodiment, the plug 2 further features a more detailed design for the limiting arm 32 of the locking tab 30. Specifically, the other end of the limiting arm 32 is provided with a second protrusion 322, which is carefully positioned on the side of the limiting block 131 away from the locking pin 20 (i.e., the upper side of the limiting block 131 in the figure). When the locking tab 30 slides in the groove 13 for locking, the locking tab 30 moves downward, and the second protrusion 322 contacts the other side of the limiting block 131 (the upper side of the limiting block 131 in the figure) and engages, preventing the locking tab 30 from sliding down excessively and damaging the connector 1. When the plug 2 is inserted into the socket 3 and needs to be locked, the user pushes the locking tab 30. The cooperation between the second protrusion 322 and the limiting block 131 ensures that the locking tab 30 can slide smoothly and accurately to the locking position, allowing the tongue 31 to be securely inserted into the socket 22 of the locking pin 20. The upper and lower sides of the limiting block 131 are respectively matched with the upper and lower protrusions of the limiting arm 32. This double-sided snap-fit ​​design means that one end of the limiting arm 32 snaps into one side of the limiting block 131 through the first protrusion 321, and the other end snaps into the other side of the limiting block 131 through the second protrusion 322, which greatly improves the stability and accuracy of the locking buckle 30 in the slide groove 13.

[0052] Reference Figure 3 as well as Figures 6 to 7 In some embodiments of this utility model, the limiting block 131 has an opening 1311, and the limiting arm 32 is provided with a third protrusion 323. The third protrusion 323 is located in the middle of the limiting arm 32 and can be engaged in the opening 1311.

[0053] In this embodiment, the plug 2 further optimizes the cooperation between the limiting block 131 and the limiting arm 32. Specifically, the limiting block 131 has an opening 1311, while the limiting arm 32 has a third protrusion 323 in the middle. The position of the opening 1311 corresponds to the position of the third protrusion 323. It is conceivable that as the locking tab 30 slides in the groove 13, the third protrusion 323 will gradually approach or move away from the opening 1311 on the limiting block 131 as the limiting arm 32 moves. When the third protrusion 323 aligns with the opening 1311, it engages in the opening 1311. This design not only provides additional stability for the sliding of the locking tab 30 in the groove 13 but also ensures that the locking tab 30 maintains accurate positioning in both the unlocked and initial states. During the process of inserting the plug 2 into the socket 3 and locking it, the third protrusion 323 engages with the opening 1311 of the limiting block 131, effectively preventing the height of the tongue 31 of the locking clip 30 from being lower than the height of the socket 22, which would hinder the sliding of the locking pin 20 in the left and right directions. After the socket 3 and plug 2 are connected, the locking clip 30 can be driven downwards. The third protrusion 323 disengages from the opening 1311 and moves downwards with the tongue 31, ensuring that the tongue 31 can be smoothly inserted into the socket 22 of the locking pin 20, forming a stable locking connection. Similarly, during the unlocking process, the locking clip 30 is driven upwards, causing the third protrusion 323 to re-engage with the opening 1311, ensuring that the locking clip 30 can smoothly and accurately slide out of the locking position, facilitating the sliding out of the locking pin 20.

[0054] Reference Figure 5In some embodiments of this utility model, a locking block 23 is provided on the outer surface of the locking pin 20, and a bayonet 14 is provided on the insulating body 10, allowing the locking block 23 to slide and engage in the bayonet 14. Specifically, the locking block 23 on the outer surface of the locking pin 20 enhances the stability of the locking pin 20 within the insulating body 10. Simultaneously, the insulating body 10 is provided with a bayonet 14 that matches the locking block 23, and the length direction of the bayonet 14 is the same as the length direction of the locking pin 20. When the locking pin 20 slides into the slot 12 of the insulating body 10, the locking block 23 gradually approaches the bayonet 14 as the locking pin 20 moves. Once the locking block 23 aligns with the bayonet 14, it slides and engages in the bayonet 14. This design effectively prevents unnecessary shaking or dislodgement of the locking pin 20 within the slot 12. During the insertion and locking of the plug 2 into the socket 3, the engagement of the locking block 23 and the locking slot 14 ensures that the locking pin 20 remains securely within the insulating body 10, thereby guaranteeing that the locking part 21 can accurately engage with the locking groove 4 of the socket 3. Furthermore, this locking design makes the connection between the locking pin 20 and the insulating body 10 more reliable during long-term use, improving the overall durability and safety of the plug 2.

[0055] In some embodiments of this utility model, a groove (not shown in the figure) is provided at the first end of the locking pin 20, and a guide post (not shown in the figure) is provided inside the insulating body 10. The guide post can pass through the groove, and an elastic element (not shown in the figure) is sleeved on the outside of the guide post. The elastic element is located in the groove, with one end of the elastic element abutting against the bottom of the groove and the other end of the elastic element abutting against the inner wall of the insulating body 10.

[0056] In this embodiment, the plug 2 specifically features a groove at its first end for the locking pin 20, which engages with a guide post inside the insulating body 10. The guide post inside the insulating body 10 allows the guide post to accurately fit into the groove at the first end of the locking pin 20 when inserted into the slot 12. This design not only provides precise guidance for the sliding of the locking pin 20 in the slot 12 but also ensures a stable position for the locking pin 20 within the slot 12. Furthermore, an elastic element is fitted around the outside of the guide post. This elastic element is positioned within the groove, with one end abutting the bottom of the groove and the other end abutting the inner wall of the insulating body 10. As the locking pin 20 slides in the slot 12, the elastic element undergoes elastic deformation according to the positional change of the locking pin 20, thereby providing continuous elastic support for the locking pin 20. This design ensures that the locking pin 20 remains tightly connected to the insulating body 10 during insertion into the socket 3 and locking, preventing it from easily shaking or falling off due to external forces. Furthermore, when it is necessary to unlock the plug 2, the elastic element helps the locking pin 20 slide smoothly out of the locked position, improving the ease of operation and reliability of the plug 2.

[0057] Reference Figure 1 , Figure 2 as well as Figure 5 According to a second aspect embodiment of the present invention, the connector 1 includes a plug 2 as described in any of the first aspects embodiments. The connector 1 also includes a socket 3, the plug 2 is inserted into the socket 3, and a snap-fit ​​groove 4 is provided at the upper end of the socket 3, with the snap-fit ​​part 21 snapping into the snap-fit ​​groove 4.

[0058] This embodiment provides a connector 1, which adopts the plug 2 design of any of the embodiments of the first aspect described above, and also includes a socket 3 that mates with the plug 2. In the specific structure, the plug 2 is designed to be inserted into the socket 3, realizing electrical connection or signal transmission between the two. The upper end of the socket 3 is provided with a snap-fit ​​groove 4, which matches the snap-fit ​​part 21 on the plug 2. When the plug 2 is inserted into the socket 3, the snap-fit ​​part 21 will accurately snap into the snap-fit ​​groove 4 at the upper end of the socket 3. This snap-fit ​​design not only ensures a stable connection between the plug 2 and the socket 3, but also prevents the plug 2 from loosening or falling off when subjected to external force. By adopting the connector 1 of this embodiment, a reliable connection between electronic devices can be achieved, ensuring stable transmission of electrical signals or data. At the same time, the snap-fit ​​design between the plug 2 and the socket 3 also makes the installation and disassembly of the connector 1 more convenient and quick, improving the ease of use and practicality of the connector 1.
