Description

Technical Field

[0001] This application belongs to the field of socket grounding technology, specifically a hybrid socket grounding structure. Background Technology

[0002] In the field of electrical equipment connections, MT socket connectors, as key components for enabling power and signal transmission between devices, are widely used in industrial control, automation equipment, medical devices, and other scenarios. With downstream industries continuously increasing their requirements for equipment operational stability and safety, the grounding performance of socket connectors has become one of the core indicators affecting overall equipment reliability. The grounding structure not only needs to effectively conduct excess current to prevent safety accidents caused by live equipment casings, but also needs to ensure continuous and stable conductivity during long-term use, adapting to vibration, temperature changes, and other operating conditions in different environments.

[0003] Currently, most mainstream MT socket connectors on the market use a spring-loaded structure for grounding to achieve conductivity between the grounding terminal and the housing. This structure uses the elastic deformation of the spring itself to keep the grounding terminal in contact with the housing, thus forming a grounding loop. To meet the elasticity and conductivity requirements of the spring, existing technologies typically use high-elasticity alloy materials to make the spring, and treat its surface with silver plating, tin plating, etc. Additionally, during the assembly of the terminal and the core, some products use a dispensing process for reinforcement to prevent displacement or loosening of the terminal during use.

[0004] However, the existing connection between the grounding terminal and the shell is achieved by the elasticity of the terminal after bending. This connection method is unstable. In addition, if the socket requires IP67 waterproof sealing, the adhesive may cause a failure to conduct electricity between the grounding terminal and the shell. Utility Model Content

[0005] The purpose of this application is to address the problem that the existing grounding terminal and the outer casing are connected by the elasticity of the bent terminal, which is unstable. In addition, if the socket requires IP67 waterproof sealing, the adhesive may cause a lack of conductivity between the grounding terminal and the outer casing. Therefore, this application provides a hybrid socket grounding structure.

[0006] The technical solution adopted in this application is as follows: a hybrid socket grounding structure, characterized in that it includes a housing assembly, a core assembly is detachably connected to one side of the housing assembly, a screw is threadedly connected to the side of the core assembly away from the housing assembly, a wire is fixedly disposed inside the core assembly, and the wire is electrically connected to a conductive terminal inside the core assembly.

[0007] By adopting the above technical solutions, the detachable connection design of the housing assembly and the core assembly enables rapid assembly and subsequent maintenance and replacement. The screw connection method replaces the traditional spring contact, structurally avoiding the problem of unstable elastic contact resistance. At the same time, the fixed electrical connection between the wire and the conductive terminal ensures the continuity of signal or power transmission and solves the risk of transmission interruption caused by poor terminal contact in the traditional structure.

[0008] In a preferred embodiment, the housing assembly includes a socket housing, one end of which is fitted with a plug and socket sealing ring, and the other end of which is fitted with a socket motor sealing ring. The inner walls of the socket housing are integrally formed with housing bosses on both sides, and the side walls of the socket housing are provided with through screw holes that are adapted to the screws.

[0009] By adopting the above technical solution, the plug and socket sealing rings and the socket motor sealing rings can achieve double sealing protection from the inlet and outlet ends of the socket shell, effectively blocking dust and moisture intrusion, meeting the requirements of IP67 waterproof and dustproof ratings, and avoiding damage to internal components due to insufficient sealing in traditional structures. At the same time, the one-piece molded shell boss on the inner wall can accurately position the glue core assembly, improve assembly accuracy, and prevent the glue core assembly from shifting inside the shell. The screw holes of the adapter screws provide a basis for the rigid connection between the grounding terminal and the shell. Compared with the traditional spring-type structure, it completely solves the problem of poor conductivity that may be caused by glue dispensing.

[0010] In a preferred embodiment, the core assembly includes a socket-integrated core, with a signal brake male terminal embedded in one side of the socket-integrated core, a power supply male terminal embedded in the side of the socket-integrated core near the signal brake male terminal, and a grounding male terminal embedded in the side of the socket-integrated core near the power supply male terminal, and the grounding male terminal is correspondingly disposed with the screw.

[0011] By adopting the above technical solution, the integrated socket core integrates signal, power, and grounding functional terminals onto the same insulating carrier, achieving physical isolation and insulation protection among the three. This avoids terminal contact short circuits or signal interference problems caused by assembly deviations in traditional separate cores. The corresponding setting of the grounding male terminal and screws provides precise docking for subsequent rigid connection between the grounding terminal and the shell via screws, ensuring stable conduction of the grounding circuit and simplifying the assembly steps of traditional grounding structures.

[0012] In a preferred embodiment, the outer wall of the integrated socket core is integrally formed with a core clip, which engages with the housing boss. The side wall of the grounding male terminal is provided with a screw through hole, and the end of the screw away from the socket housing passes through the screw through hole and the screw hole in sequence, and is threadedly connected to the socket housing.

[0013] By adopting the above technical solution, the snap-fit ​​between the core clip and the housing boss enables rapid pre-fixation of the core assembly and the housing assembly. Initial positioning can be completed without additional tooling, reducing assembly difficulty and improving assembly efficiency. The screws pass through the screw holes of the grounding male terminal and the screw holes of the housing in sequence, so that the grounding terminal and the housing form a rigid threaded connection. Compared with the traditional spring-type elastic contact, the contact resistance is more stable, and the problem of poor pin removal caused by the failure of the spring force of the grounding terminal is completely solved, extending the service life of the grounding structure.

[0014] In a preferred embodiment, the end of the wire near the signal brake male terminal is welded and fixed to the surface of the signal brake male terminal. The signal brake male terminal, the power supply male terminal, and the grounding male terminal are arranged linearly within the integrated core of the socket, and the three do not contact each other.

[0015] By adopting the above technical solutions, the welding and fixing method of the wire and the signal brake male terminal has higher connection strength and more stable conductivity, avoiding wire loosening or poor contact caused by vibration during long-term use. The linear arrangement and non-contact design of the three types of terminals realize functional zoning within the limited core space, maximizing the use of space while further reducing the risk of signal interference and power short circuit, and improving the safety and reliability of the overall structure.

[0016] In a preferred embodiment, both the plug and socket sealing ring and the socket motor sealing ring are made of elastic rubber material. The inner wall of the plug and socket sealing ring is tightly fitted to the outer wall of the socket housing, and the inner wall of the socket motor sealing ring is tightly fitted to the outer wall of the socket housing.

[0017] By adopting the above technical solution, the sealing ring made of elastic rubber has good deformation ability and aging resistance, and can adapt to temperature changes and vibration conditions in different environments, maintaining sealing performance for a long time. The tight fit between the inner wall of the sealing ring and the outer wall of the socket shell eliminates the gap between the two, preventing dust and moisture from entering through the gap, further enhancing the waterproof and dustproof effect. At the same time, the elastic fit design can also buffer the impact of external vibration on the internal components of the shell, improving the overall vibration resistance of the socket. It is suitable for industrial control, medical devices and other scenarios with high requirements for environmental adaptability.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0019] In this application, under the above design, the fixing method between the terminal and the glue core and the shell is changed, which improves the problem of unstable elastic contact resistance between the terminal and the shell. At the same time, the grounding terminal is simplified and the contact is more stable, which is suitable for mass production. It also improves the problem of glue affecting grounding resistance and reduces production costs. Attached Figure Description

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] Reference Figure 1-4 The hybrid socket grounding structure includes a housing assembly 11, a core assembly 10 detachably connected to one side of the housing assembly 11, a screw 8 threadedly connected to the side of the core assembly 10 away from the housing assembly 11, and a wire 9 fixedly installed inside the core assembly 10. The wire 9 is electrically connected to the conductive terminal inside the core assembly 10. The detachable connection design of the housing assembly 11 and the core assembly 10 enables quick assembly and subsequent maintenance and replacement. The screw connection method replaces the traditional spring contact, structurally avoiding the problem of unstable elastic contact resistance. At the same time, the fixed electrical connection between the wire and the conductive terminal ensures the continuity of signal or power transmission and solves the risk of transmission interruption caused by poor terminal contact in the traditional structure.

[0027] Reference Figure 1-4The housing assembly 11 includes a socket housing 2. One end of the socket housing 2 is fitted with a plug and socket sealing ring 1, and the other end is fitted with a socket and motor sealing ring 3. The inner walls of the socket housing 2 are integrally formed with housing bosses 2a on both sides. The side walls of the socket housing 2 are provided with through screw holes 2b, which are adapted to screws 8. Under the action of the plug and socket sealing ring 1 and the socket and motor sealing ring 3, double sealing protection can be achieved from the inlet and outlet ends of the socket housing, effectively blocking dust and moisture intrusion, meeting the requirements of IP67 waterproof and dustproof rating, and avoiding damage to internal components due to insufficient sealing in traditional structures. At the same time, the integrally formed housing bosses 2a on the inner wall can be precisely positioned with the glue core assembly 10, improving assembly accuracy and preventing the glue core assembly 10 from shifting inside the housing. The screw holes of the screws 8 provide a basis for the rigid connection between the grounding terminal and the housing. Compared with the traditional spring-type structure, it completely solves the problem of poor conductivity that may be caused by glue dispensing.

[0028] Reference Figure 1-4 The core assembly 10 includes an integrated socket core 4. A signal brake male terminal 5 is embedded in one side of the integrated socket core 4. A power male terminal 6 is embedded in the side of the integrated socket core 4 near the signal brake male terminal 5. A grounding male terminal 7 is embedded in the side of the integrated socket core 4 near the power male terminal 6. The grounding male terminal 7 is correspondingly set with a screw 8. The integrated socket core integrates the three functional terminals of signal, power and grounding into the same insulating carrier, realizing physical isolation and insulation protection of the three, avoiding the terminal contact short circuit or signal interference problems caused by assembly deviation of traditional split cores. The corresponding setting of the grounding male terminal 7 and the screw 8 provides a precise docking for the subsequent rigid connection between the grounding terminal and the shell through the screw 8, ensuring the stable conduction of the grounding circuit and simplifying the assembly steps of the traditional grounding structure.

[0029] Reference Figure 1-4 The outer wall of the integrated socket core 4 is integrally formed with a core clip 4a, which engages with the housing boss 2a. The side wall of the grounding male terminal 7 has a through hole 7a. The end of the screw 8 away from the socket housing 2 passes through the through hole 7a and the screw hole 2b in sequence, and is threadedly connected to the socket housing 2. The engagement between the core clip 4a and the housing boss 2a enables quick pre-fixing of the core assembly 10 and the housing assembly 11. Initial positioning can be completed without additional tooling, reducing assembly difficulty and improving assembly efficiency. The screw 8 passes through the through hole 7a of the grounding male terminal 7 and the screw hole of the housing in sequence, so that the grounding terminal and the housing form a rigid threaded connection. Compared with the traditional spring-type elastic contact, the contact resistance is more stable, and the problem of poor pin removal caused by the failure of the spring force of the grounding terminal is completely solved, extending the service life of the grounding structure.

[0030] Reference Figure 1-4The end of wire 9 closest to the signal brake male terminal 5 is welded and fixed to the surface of the signal brake male terminal 5. The signal brake male terminal 5, power male terminal 6, and grounding male terminal 7 are arranged linearly within the integrated core 4 of the socket, and the three do not contact each other. The welding and fixing method between wire 9 and signal brake male terminal 5 results in higher connection strength and more stable conductivity, avoiding loosening or poor contact of wire 9 due to vibration during long-term use. The linear arrangement and non-contact design of the three types of terminals achieves functional zoning within the limited core space, maximizing space utilization while further reducing the risk of signal interference and power short circuits, and improving the safety and reliability of the overall structure.

[0031] Reference Figure 1-4 Both the plug and socket sealing ring 1 and the socket motor sealing ring 3 are made of elastic rubber. The inner wall of the plug and socket sealing ring 1 is tightly fitted to the outer wall of the socket housing 2, and the inner wall of the socket motor sealing ring 3 is tightly fitted to the outer wall of the socket housing 2. The elastic rubber sealing ring has good deformation ability and aging resistance, and can adapt to temperature changes and vibration conditions in different environments, maintaining sealing performance for a long time. The tight fit between the inner wall of the sealing ring and the outer wall of the socket housing eliminates the gap between the two, preventing dust and moisture from entering from the gap, further enhancing the waterproof and dustproof effect. At the same time, the elastic fit design can also buffer the impact of external vibration on the internal components of the housing, improving the overall vibration resistance of the socket. It is suitable for industrial control, medical devices and other scenarios with high environmental adaptability requirements.

[0032] The implementation principle of the hybrid socket grounding structure embodiment of this application is as follows:

[0033] During installation, the wire 9 is cut and stripped, and soldered to the surface of the signal brake male terminal 5 in the core assembly 10. Then, the core clip 4a in the core assembly 10 is aligned with the position of the housing boss 2a in the housing assembly 11 and fastened. Finally, the grounding male terminal 7 is connected to the socket housing 2 with the screw 8 to complete the socket connector assembly. The connection method between the grounding terminal and the socket housing is changed from a spring-loaded connection to a screw connection, which stabilizes the conduction between the grounding terminal and the socket housing and improves the potential pin retraction defects of the grounding terminal.
