[0016] Compared to existing connectors, this invention effectively achieves spatial isolation and functional division of electrical connections through the relative arrangement of the first and second mating cavities in the main housing structure and the introduction of a mating partition. This design not only improves the internal structural compactness of the connector assembly but also ensures the independence and safety of different circuits or signal paths, reducing the risk of mutual interference. Secondly, the innovative application of a primary locking mechanism—that is, the interaction between the mounting slots on both sides of the second mating cavity and the mounting clips on the second electrical component—achieves quick and secure installation of the electrical component. This mechanism simplifies the installation process, improves work efficiency, and ensures the reliability of the electrical component under vibration or shock conditions, enhancing the connector's environmental adaptability. Most importantly, the introduction of a secondary locking mechanism further enhances the connector's safety performance. The fixed steps on the mounting cover, in conjunction with the fixed slots on the main housing's locking platform, not only provide additional fixing support for the second electrical component but also form an additional safety barrier. This dual-locking design greatly reduces the risk of electrical faults caused by loosening or detachment of the electrical component, ensuring the stable operation of the entire circuit system. Furthermore, this connector assembly also demonstrates good maintainability and flexibility. When maintenance or replacement of electrical components is required, the operation can be easily completed by releasing the secondary lock (i.e., separating the fixed step from the fixed slot) and the primary lock (i.e., separating the assembly clip from the assembly slot), without the need for a complicated disassembly process. This invention, through its unique design concept and superior technical performance, provides a safer, more reliable, and more efficient solution for the field of electrical connections.

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. Figures 1-6As shown, in one embodiment of this utility model, a secondary locking safety connector assembly is provided, including a main housing 1, a mounting cover 2, a first power-connecting element 3, and a second power-connecting element 4. The main housing 1 is provided with a first insertion cavity 11, a second insertion cavity 12, and an insertion partition 13. The first insertion cavity 11 and the second insertion cavity 12 are disposed opposite to each other at both ends of the main housing 1. The insertion partition 13 is disposed between the first insertion cavity 11 and the second insertion cavity 12. A fastening platform 14 is provided on one side of the main housing 1. The fastening platform 14 is provided with a fixing slot 141. The mounting cover 2 is disposed on the fastening platform 14 and is provided with a fixing step 21. The first power-connecting element 3 is disposed in the first insertion cavity 11. The second power-connecting element 4 is disposed within the second insertion cavity 12. The first power-connecting element 3 is provided with a first power-connecting terminal 31, one end of which passes through the insertion partition 13 and connects to the second power-connecting element 4. Assembly slots 121 are provided on both sides of the second insertion cavity 12, and the second power-connecting element 4 is provided with an assembly buckle 41. The assembly buckle 41 is used to engage with the assembly slots 121 to fix the second power-connecting element 4 within the second insertion cavity 12, achieving a primary locking. The fixing step 21 is used to engage with the fixing slot 141, one end of which connects to the second insertion cavity 12. The fixing step 21 is used to fix the second power-connecting element 4 within the second insertion cavity 12, achieving a secondary locking. This embodiment effectively achieves spatial isolation and functional division of electrical connections through the relative arrangement of the first insertion cavity 11 and the second insertion cavity 12 in the main housing 1 structure and the introduction of the insertion partition 13. This design not only improves the internal structural compactness of the connector assembly but also ensures the independence and safety of different circuits or signal paths, reducing the risk of mutual interference. Secondly, the innovative application of a primary locking mechanism—the engagement of the mounting slots 121 on both sides of the second mating cavity 12 with the mounting clips 41 on the second electrical component 4—achieves quick and secure installation of the electrical component. This mechanism simplifies the installation process, improves work efficiency, and ensures the reliability of the electrical component under vibration or shock conditions, enhancing the connector's environmental adaptability. Most importantly, the introduction of a secondary locking mechanism further enhances the connector's safety performance. The engagement of the fixing step 21 on the mounting cover 2 with the fixing slot 141 on the main housing 1's locking platform 14 not only provides additional fixing support for the second electrical component 4 but also forms an additional safety barrier. This dual locking design greatly reduces the risk of electrical failures caused by loosening or detachment of the electrical component, ensuring the stable operation of the entire circuit system. Furthermore, this connector assembly also demonstrates good maintainability and flexibility.When maintenance or replacement of electrical components is required, 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, through its unique design concept and superior technical effect, provides a safer, more reliable, and more efficient solution for the field of electrical connections.

[0027] A clamping and positioning strip 111 is provided inside the first insertion cavity 11. The clamping and positioning strip 111 is used to clamp and fix the first electrical contact element 3 inside the first insertion cavity 11. In this embodiment, the clamping and positioning strip 111 is ingeniously designed to effectively clamp and firmly fix the first electrical contact element 3 inside the first insertion cavity 11, thereby ensuring the stability and reliability of the connector during insertion, removal, and long-term use. Specifically, the clamping and positioning strip 111, through its unique clamping mechanism, can offset the risk of loosening of the electrical contact element caused by external factors such as vibration and impact, greatly reducing electrical faults caused by poor contact. This not only improves the overall electrical performance of the connector but also significantly extends its service life. In addition, this structure simplifies the connector assembly process. Operators can easily install the electrical contact element into place and achieve stable fixation without using additional tools or complicated steps. This not only improves production efficiency but also reduces the quality risk caused by assembly errors.

[0028] A power-connecting slot 15 is provided on one side of the main housing 1, and a power-connecting buckle 32 is provided on one side of the first power-connecting element 3. The power-connecting buckle 32 is used to cooperate with the power-connecting slot 15 to fix the first power-connecting element 3 in the first insertion cavity 11. In this embodiment, the carefully designed power-connecting slot 15 on one side of the main housing 1 not only provides a precise mating position for the first power-connecting element 3, but also ensures guidance during the connection process, simplifies the installation steps, and improves operating efficiency. The power-connecting buckle 32 configured on one side of the first power-connecting element 3, as a key component that cooperates with the power-connecting slot 15, is designed with full consideration of the reliability and ease of use of locking. When the power-connecting buckle 32 is accurately engaged in the power-connecting slot 15, not only is a tight electrical contact achieved, but also, through a physical locking mechanism, it effectively prevents the power-connecting element from loosening or falling off due to vibration or external force during use, thereby ensuring the stability and durability of the connector's signal transmission. In addition, this structural design also gives the secondary locking connector additional safety performance. Even under extreme operating conditions, such as strong vibration and impact, the tight fit between the power connector buckle 32 and the power connector slot 15 ensures the reliability of the electrical connection, avoiding system failures or safety accidents that may be caused by connection failure. A first limiting groove is provided at the port of the first insertion cavity 11, and a first limiting platform is provided for the first power connector 3. The first limiting platform cooperates with the first limiting groove to limit the first power connector 3 within the first insertion cavity 11. In this embodiment, through the tight fit between the first limiting platform and the first limiting groove, the first power connector 3 is effectively limited within the insertion cavity, thereby preventing loosening or detachment due to external forces or vibrations, ensuring the continuity and stability of the electrical connection. Secondly, this limiting structure helps simplify the installation and disassembly process of the connector. When the first power connector 3 is inserted, the limiting platform automatically slides into the limiting groove for quick positioning; when disassembly is required, the power connector can be pulled out by overcoming only minor resistance, without additional unlocking steps, improving operational efficiency. Furthermore, this design also enhances the protective performance of the connector. The combination of the limiting platform and the limiting groove can prevent external contaminants such as moisture and dust from entering the mating cavity, thus providing a certain degree of protection for the internal electrical components and extending the service life of the connector.

[0029] An assembly positioning groove 112 is provided at the port of the first insertion cavity 11, and a positioning step 113 is provided at the bottom of the first insertion cavity 11. The mounting cover plate 2 is provided with an end face sealing plate 22, which 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 insertion cavity 11 cooperates with the assembly positioning strip 221 on the end face sealing plate 22 of the mounting cover plate 2, realizing precise axial positioning. This design ensures that the components can quickly and accurately align during the assembly process of the connector, effectively avoiding performance degradation or failure caused by assembly errors. Secondly, the positioning step 113 provided at the bottom of the first insertion cavity 11 and the positioning groove 222 on the end face sealing plate 22 interlock, providing additional radial positioning support for the connector. This design not only enhances the stability of the connector structure, but also further improves its resistance to vibration and shock in complex environments, ensuring the continuity and reliability of signal transmission.

[0030] The fastening platform 14 has connecting buckles 142 and limiting support platforms 143 on both sides. The mounting cover plate 2 has connecting slots 23 and limiting support grooves 24 on both sides. The connecting buckles 142 are used to engage with the connecting slots 23, and the limiting support platforms 143 are used to engage with the limiting support grooves 24, so as to fasten the mounting cover plate 2 onto the fastening platform 14. In this embodiment, the precise engagement of the connecting buckles 142 and the connecting slots 23 effectively prevents the mounting cover plate 2 from moving in the horizontal direction, while the interaction between the limiting support platforms 143 and the limiting support grooves 24 further restricts the displacement of the mounting cover plate 2 in the vertical direction, thereby achieving a stable fastening effect. Secondly, this structural design improves the overall stability and reliability of the secondary locking connector. During installation, the mounting cover plate 2 can easily and accurately mate with the fastening platform 14 without complex adjustments or additional fixing measures. This not only simplifies the installation process but also reduces the risk of failure due to improper installation. In addition, this structure also has good adaptability and compatibility. The design of the connecting buckle 142 and the connecting slot 23 is flexible and can adapt to mounting covers 2 of different sizes and shapes, thereby expanding the application range of the secondary locking connector.

[0031] A pressure block 144 is provided at the opening of the fixed slot 141, which is used to press the fixed step 21 onto the fixed slot 141. In this embodiment, the application of the pressure block 144 effectively enhances the stability of the connector under external force or vibration conditions, avoiding connection failure caused by loosening or displacement. Its ingenious design ensures a tight fit between the fixed step 21 and the fixed slot 141 during repeated insertions and removals or long-term use, thereby guaranteeing stable signal transmission and reliable electrical performance of the connector. In addition, the pressure block 144 simplifies the connector assembly process and improves production efficiency. Operators can easily achieve quick pressing and locking of the fixed step 21 without the need for complex tools or additional steps, reducing operational difficulty and time costs.

[0032] The first contact element 3 is a sheet-shaped contact piece, and multiple first contact terminals 31 are provided. Each first contact terminal 31 is located at one end of the sheet-shaped contact piece, and tight-fitting latches 33 are provided on the upper and lower sides of the first contact element 3. In this embodiment, the first contact element 3 adopts a sheet-shaped contact piece design, which significantly enhances the conductivity and stability of the contact element. The sheet-shaped structure makes current transmission more uniform, reducing energy loss and heat generation problems caused by poor contact or excessive resistance. Secondly, the multiple first contact terminals 31 meet the connector's requirement for multi-line transmission. These terminals are neatly arranged at one end of the sheet-shaped contact piece, which not only facilitates mating with corresponding connectors but also improves the reliability and stability of the connection. Furthermore, the tight-fitting latches 33 provide an additional locking mechanism for the connector. These latches can tightly engage with the upper and lower sides of the connector, effectively preventing the contact element from loosening or falling off due to external forces. This design not only improves the durability of the connector but also reduces the failure rate caused by poor connection.

[0033] The second power connection element 4 includes a second power connection terminal 42 and a connecting wire 43. The end of the second power connection terminal 42 opposite to the first power connection terminal 31 is provided with a power connection socket 421, into which the first power connection terminal 31 is inserted. A wire clip 422 is provided at one end of the second power connection terminal 42 to fix the connecting wire 43. Specifically, a contact spring 423 is provided at the port of the second power connection terminal 42. Multiple contact springs 423 are provided, with one end extending towards and contacting the first power connection terminal 31. In this embodiment, the design of the second power connection element 4 cleverly combines the second power connection terminal 42 and the connecting wire 43, achieving a precise electrical connection through the mating of the power connection socket 421 and the first power connection terminal 31. This design not only simplifies the connection process but also enhances the connection's robustness and reduces the risk of electrical failures due to poor contact. When the first electrical terminal 31 is inserted into the electrical socket 421, the multiple contact springs 423 at the port of the second electrical terminal 42 play a crucial role. These contact springs 423 are numerous, ensuring a wider contact area, and their design, extending towards the first electrical terminal 31, allows them to fit tightly against the electrical terminal, forming a reliable electrical path. This tight contact not only improves current transmission efficiency but also effectively reduces changes in contact resistance caused by vibration or temperature variations, thus ensuring the stability of the connector during long-term use. Furthermore, the wire clip 422 at one end of the second electrical terminal 42 facilitates the secure fixing of the connecting wire 43. This design not only makes the connecting wire 43 more firmly connected to the electrical terminal, preventing electrical connection interruptions due to loose wiring, but also enhances the overall reliability and durability of the connector.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
