The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Figure 1 to Figure 6As shown, in one embodiment of the present invention, a secondary locking safety connector assembly is involved, including a main shell 1, an installation cover 2, a first power connection element 3 and a second power connection element 4, the main shell 1 is provided with a first plug-in cavity 11, a second plug-in cavity 12 and a plug-in partition 13, the first plug-in cavity 11 and the second plug-in cavity 12 are relatively arranged at two ends of the main shell 1, the plug-in partition 13 is arranged between the first plug-in cavity 11 and the second plug-in cavity 12, a buckling platform 14 is arranged on one side of the main shell 1, the buckling platform 14 is provided with a fixed card slot 141, the installation cover 2 is arranged on the buckling platform 14, and the installation cover 2 is provided with a fixed step 21; the first power connection element 3 is arranged in the first plug-in cavity 11, The second power connection element 4 is arranged in the second plug-in cavity 12, the first power connection element 3 is provided with a first power connection terminal 31, one end of the first power connection terminal 31 passes through the plug-in partition 13 and is connected to the second power connection element 4; the second plug-in cavity 12 is provided with assembly slots 121 on both sides, the second power connection element 4 is provided with an assembly buckle 41, the assembly buckle 41 is used to cooperate with the assembly slot 121 to fix the second power connection element 4 in the second plug-in cavity 12 to achieve a primary lock; the fixing step 21 is used to cooperate with the fixing slot 141, one end of the fixing slot 141 is connected to the second plug-in cavity 12, and the fixing step 21 is used to fix the second power connection element 4 in the second plug-in cavity 12 to achieve a secondary lock. In this embodiment, the relative arrangement of the first plug-in cavity 11 and the second plug-in cavity 12 of the main housing 1 structure and the introduction of the plug-in partition 13 effectively realizes the spatial isolation and functional division of electrical connections. This design not only improves the compactness of the internal structure of the connector assembly, but also ensures the independence and safety of different circuits or signal paths, and reduces the risk of mutual interference. Secondly, the innovative use of the primary locking mechanism, that is, the assembly card slots 121 on both sides of the second plug-in cavity 12 cooperate with the assembly buckles 41 on the second power connection element 4, to achieve rapid and stable installation of the power connection element. This mechanism simplifies the installation process and improves work efficiency, while ensuring the reliability of the power connection element under vibration or impact conditions and enhancing the environmental adaptability of the connector.

The fixed step 21 on the mounting cover 2 cooperates with the fixed card slot 141 on the buckle platform 14 of the main housing 1, which not only provides additional fixing support for the second power connection element 4, but also forms an additional safety barrier. This double locking design greatly reduces the risk of electrical failure caused by loosening or falling off of the power connection element, and ensures the stable operation of the entire circuit system. In addition, the connector assembly also embodies good maintainability and flexibility.When it is necessary to maintain or replace the electrical connection components, the operation can be easily completed by releasing the secondary lock (i.e., separating the fixed step 21 from the fixed slot 141) and the primary lock (i.e., separating the assembly buckle 41 from the assembly slot 121), without the need for a complicated disassembly process. This embodiment provides a safer, more reliable, and more efficient solution for the electrical connection field through a unique design concept and excellent technical effects.

[0021] A clamping and positioning strip 111 is provided in the first plug-in cavity 11, and the clamping and positioning strip 111 is used to clamp and fix the first power connection element 3 in the first plug-in cavity 11. In this embodiment, the clamping and positioning strip 111 is exquisitely designed, and can effectively clamp and firmly fix the first power connection element 3 in the first plug-in cavity 11, thereby ensuring the stability and reliability of the connector during plugging and unplugging and long-term use. Specifically, the clamping and positioning strip 111 can offset the risk of loosening of the power connection element caused by external factors such as vibration and impact through its unique clamping mechanism, and greatly reduce electrical failures caused by poor contact. This not only improves the overall electrical performance of the connector, but also significantly extends its service life. In addition, the structure also simplifies the assembly process of the connector. The operator can easily install the power connection element in place and achieve stable fixation without using additional tools or complicated steps. This not only improves production efficiency, but also reduces quality risks caused by assembly errors.

[0022] A power connection slot 15 is provided on one side of the main housing 1, and a power connection buckle 32 is provided on one side of the first power connection element 3. The power connection buckle 32 is used to cooperate with the power connection slot 15 to fix the first power connection element 3 in the first plug-in cavity 11. In this embodiment, the carefully designed power connection slot 15 on one side of the main housing 1 not only provides a precise docking position for the first power connection element 3, but also ensures the guidance during the connection process, simplifies the installation steps, and improves the operation efficiency. The power connection buckle 32 configured on one side of the first power connection element 3, as a key component that cooperates with the power connection slot 15, is designed with full consideration of the reliability and ease of use of the locking. When the power connection buckle 32 is accurately inserted into the power connection slot 15, not only the tightness of the electrical contact is achieved, but also the physical locking mechanism effectively prevents the power connection element from loosening or falling off due to vibration or external force during use, thereby ensuring the stability and durability of the signal transmission of the connector. In addition, this structural design also gives the secondary locking connector additional safety performance. Even under extreme working conditions, such as strong vibration and impact, the close fit between the power connection buckle 32 and the power connection slot 15 can still ensure the reliability of the electrical connection, avoiding system failure or safety accidents that may be caused by connection failure. A first limiting groove is provided at the port of the first plug-in cavity 11, and the first power connection element 3 is provided with a first limiting platform, which is used to cooperate with the first limiting groove to limit the first power connection element 3 in the first plug-in cavity 11. In this embodiment, through the close fit between the first limiting platform and the first limiting groove, the first power connection element 3 is effectively limited in the plug-in cavity, thereby avoiding loosening or falling off caused by external force or vibration, and ensuring the continuity and stability of the electrical connection. Secondly, this limiting structure helps to simplify the installation and removal process of the connector. When the first power connection element 3 is inserted, the limiting platform will automatically slide into the limiting groove to achieve rapid positioning; and when it needs to be removed, it only needs to overcome a small resistance to pull out the power connection element, without the need for additional unlocking steps, thereby improving the operating efficiency. In addition, the design also enhances the protective performance of the connector. The cooperation between the limit platform and the limit groove can prevent external pollutants such as moisture and dust from entering the plug-in cavity, play a certain protective role on the internal electrical components, and extend the service life of the connector.

[0023] An assembly positioning groove 112 is provided at the port of the first plug-in cavity 11, a positioning step 113 is provided at the bottom of the first plug-in cavity 11, and the mounting cover plate 2 is provided with an end face sealing plate 22. The end face sealing plate 22 is provided with an assembly positioning strip 221 and a positioning groove 222. The assembly positioning strip 221 is used to cooperate with the assembly positioning groove 112 for positioning and assembly, and the positioning step 113 is used to position the groove 222 for assembly and positioning of the end face sealing plate 22. In this embodiment, the assembly positioning groove 112 provided at the port of the first plug-in cavity 11 cooperates with the assembly positioning strip 221 of the end face sealing plate 22 on the mounting cover plate 2 to achieve precise axial positioning. This design ensures that during the assembly process of the connector, the various components can be quickly and accurately docked, effectively avoiding performance degradation or failure problems caused by assembly errors. Secondly, the positioning step 113 provided at the bottom of the first plug-in cavity 11 is interlocked with the positioning groove 222 on the end face sealing plate 22, providing additional radial positioning support for the connector. This design not only enhances the stability of the connector structure, but also further improves its ability to resist vibration and impact in complex environments, ensuring the continuity and reliability of signal transmission.

[0024] The two sides of the buckle platform 14 are provided with a connecting buckle 142 and a limiting support platform 143, and the two sides of the installation cover plate 2 are provided with a connecting card slot 23 and a limiting support slot 24, the connecting buckle 142 is used to match the connecting card slot 23, and the limiting support platform 143 is used to match the limiting support slot 24, so as to buckle the installation cover plate 2 on the buckle platform 14. In this embodiment, the precise matching of the connecting buckle 142 and the connecting card slot 23 effectively prevents the movement of the installation cover plate 2 in the horizontal direction, and the interaction between the limiting support platform 143 and the limiting support slot 24 further limits the displacement of the installation cover plate 2 in the vertical direction, thereby achieving a stable buckling effect. Secondly, this structural design improves the overall stability and reliability of the secondary locking connector. During the installation process, the installation cover plate 2 can be easily and accurately docked with the buckle platform 14 without complicated adjustments or additional fixing measures. This not only simplifies the installation process, but also reduces the risk of failure caused by improper installation. In addition, the structure also has good adaptability and compatibility. The design of the connecting buckle 142 and the connecting slot 23 has a certain degree of flexibility and can adapt to installation covers 2 of different sizes and shapes, thereby expanding the application range of the secondary locking connector.

[0025] A pressing block 144 is provided at the notch of the fixed slot 141, and the pressing block 144 is used to press the fixed step 21 onto the fixed slot 141. In this embodiment, the application of the pressing block 144 effectively enhances the stability of the connector under external force or vibration conditions, and avoids the problem of connection failure caused by looseness or displacement. Its sophisticated design can ensure the tight fit between the fixed step 21 and the fixed slot 141 during multiple plugging and unplugging or long-term use, thereby ensuring the stable transmission of the connector signal and the reliability of the electrical performance. In addition, the pressing block 144 also simplifies the assembly process of the connector and improves production efficiency. The operator can easily achieve the rapid compression and locking of the fixed step 21 without the help of complex tools or additional steps, reducing the difficulty of operation and time cost.

[0026] The first power connection element 3 is a sheet-shaped power connection sheet, and a plurality of the first power connection terminals 31 are provided. The first power connection terminals 31 are arranged at one end of the sheet-shaped power connection sheet, and the upper and lower sides of the first power connection element 3 are provided with tight-fitting buckles 33. In this embodiment, the first power connection element 3 adopts a sheet-shaped power connection sheet design, which significantly enhances the conductivity and stability of the power connection element. The sheet-shaped structure makes the current transmission more uniform, and reduces the energy loss and heating problems caused by poor contact or excessive resistance. Secondly, the setting of multiple first power connection terminals 31 meets the connector's demand for multi-line transmission. These terminals are neatly arranged at one end of the sheet-shaped power connection sheet, which is not only convenient for docking with the corresponding plug-in connector, but also improves the reliability and stability of the connection. Furthermore, the setting of the tight-fitting buckle 33 provides an additional locking mechanism for the connector. These buckles can be tightly buckled on the upper and lower sides of the connector, effectively preventing the power connection element from loosening or falling off due to external force. This design not only improves the durability of the connector, but also reduces the failure rate caused by poor connection.

[0027] The second power connection element 4 includes a second power connection terminal 42 and a connecting wire 43. The second power connection terminal 42 is provided with a power connection socket 421 at one end opposite to the first power connection terminal 31. The first power connection terminal 31 is used to be inserted into the power connection socket 421. One end of the second power connection terminal 42 is provided with a wiring clamp 422, and the wiring clamp 422 is used to fix the connecting wire 43. Specifically, a contact spring 423 is provided at the port of the second power connection terminal 42. The contact spring 423 is provided in plurality, and one end of the plurality of contact springs 423 extends toward the first power connection terminal 31 and contacts the first power connection terminal 31. In this embodiment, the design of the second power connection element 4 integrates the ingenious combination of the second power connection terminal 42 and the connecting wire 43, and realizes precise electrical connection by connecting the power connection socket 421 with the first power connection terminal 31. This design not only simplifies the connection process, but also enhances the firmness of the connection, and reduces the risk of electrical failure caused by poor contact. When the first power terminal 31 is inserted into the power socket 421, the multiple contact springs 423 at the port of the second power terminal 42 play a crucial role. These contact springs 423 are not only numerous, ensuring a wider contact area, but also their design of extending toward the first power terminal 31 can fit tightly on the power terminal to form a reliable electrical path. This close contact not only improves the current transmission efficiency, but also effectively reduces the change in contact resistance caused by vibration or temperature changes, thereby ensuring the stability of the connector in long-term use. In addition, the design of the wiring clamp 422 at one end of the second power terminal 42 provides convenience for fixing the connecting wire 43. This design not only makes the connecting wire 43 more firmly connected to the power terminal, avoiding the interruption of electrical connection due to loose lines, but also improves the reliability and durability of the entire connector.
