In this embodiment, the interconnecting structure between the plug-in cavity 11 and the fixed cavity 12 facilitates the connection of the electrical connection component 4 to external devices while ensuring accurate positioning during the connection process. This effectively reduces signal interruptions or current fluctuations caused by poor contact, thereby improving the reliability of the electrical connection. The insulating fixed assembly 3 is built into the metal shell 2. This design not only enhances the mechanical strength of the overall structure but also effectively isolates the current through the insulating material, preventing the risk of short circuits and ensuring the safety of the connector in complex electromagnetic environments. Furthermore, the stable support provided by the insulating fixed assembly 3 for the electrical connection component 4 reduces component loosening due to vibration or impact, thereby extending the product's service life. The front, rear, and side latches 21, 22, and 23 on the metal shell 2 tightly mate with corresponding slots in the fixed cavity 12, forming a multi-point locking mechanism. This structural design not only simplifies the installation process and improves installation efficiency, but also ensures the stability of the metal shell 2 within the fixed cavity 12, maintaining the connector's stable operation even in extreme operating environments and preventing connection failure due to loosening. This embodiment provides a strong guarantee for efficient, safe, and reliable connection between electronic devices through reasonable structural design, excellent electrical performance, and stable mechanical connection, and is widely used in communications, automotive electronics, industrial automation and other fields.

[0026] Housing 1 is provided with a hook 13 above insertion cavity 11, and housing 1 is provided with an assembly positioning strip 14 below insertion cavity 11, with a positioning pin 141 disposed on said assembly positioning strip 14. In this embodiment, the design of hook 13 effectively ensures that the connector can be quickly and securely locked into the corresponding interface during insertion, reducing the problem of loosening or falling off due to improper insertion. At the same time, the precise docking of the assembly positioning strip 14 below with the positioning pin 141 not only simplifies the assembly process, but also ensures precise guidance and positioning of the connector during installation, avoiding poor connection or damage caused by positional offset.

[0027] The housing 1 is provided with reinforcement plates 15 on either side of the mounting cavity 12.

[0029] The metal shell 2 covers the insulating fixing component 3 by stamping. The metal shell 2 includes a front stop buckle 24 and a backstop baffle 25. The front stop buckle 24 and the backstop baffle 25 are respectively used to fix the two ends of the insulating fixing component 3. In this embodiment, the setting of the front stop buckle 24 and the backstop baffle 25 respectively implements precise and stable fixation of the two ends of the insulating fixing component 3, effectively preventing the component from being displaced or loosened during the operation of the connector, and ensuring the stability and reliability of the connection. The stamping and covering of the metal shell 2 not only enhances the strength and durability of the overall structure, but also provides a good shielding effect, can resist external electromagnetic interference, and protect the purity of internal signal transmission, which is crucial for improving the performance of the connector in complex electromagnetic environments.

[0030] The metal shell 2 includes an upper shell 26 and a lower shell 27, which interlock to secure the insulating fixing assembly 3. In this embodiment, the metal material gives the shell excellent conductivity and electromagnetic shielding capabilities, effectively reducing interference during signal transmission and ensuring the accuracy and stability of data transmission. Secondly, the tight interlocking design of the upper and lower shells 27 not only ensures the stable installation of the insulating fixing assembly 3 and prevents it from loosening or falling off, but also enhances the structural strength and durability of the connector, enabling it to withstand physical impact and vibration in the external environment and extend its service life.

The snap-fit ​​blocks 322 are configured to engage with the snap-fit ​​grooves 331. The clamping portion 32 is formed by the interlocking of two clamping plates, and the fixing portion 33 is formed by the interlocking of two fixing plates. The electrical connection element 4 includes a connection portion 41, a fixed end 42, and a connection pin 43. The connection portion 41 is provided with a connection clamping slot 411, one end of which extends into the insertion and fixing hole 311. The fixed end 42 is disposed within the clamping portion 32, and the connection pin 43 is disposed within the fixing portion 33. In this embodiment, the orderly arrangement of the front portion 31, the clamping portion 32, and the fixing portion 33 not only enhances structural stability but also simplifies the installation process. The insertion and fixing hole 311 of the front portion 31 precisely mates with the connection clamping slot 411 of the electrical connection element 4, ensuring a reliable electrical connection. Furthermore, the clever coordination between the connecting plate 312 and the connecting slot 321 enhances the sealing and insulation performance of the overall connection. The clamping portion 32 tightly locks with the locking slot 331 of the fixing portion 33 via double-sided snap-fit ​​blocks 322, achieving dual fixation of the electrical connection element 4 and effectively preventing loosening or dislodging due to vibration or impact. The interlocking structure of the clamping plate and the fixing plate further enhances the mechanical strength and durability of the assembly. The integrated design of the power connection portion 41, fixing portion 33, and power pin 43 of the power connection element 4 optimizes the current transmission path and reduces resistance losses. Furthermore, the fixing end 42 is embedded within the clamping portion 32, effectively protecting the power pin 43 from external interference, thereby improving the overall safety and service life of the connector.
