Description
Technical Field
[0001] This utility model relates to the field of electrical connector assembly technology, and in particular to electromagnetically shielded electrical connector terminals. Background Technology
[0002] Electrical connector terminals are metal parts in electrical connectors used for electrical connection with wires, circuit boards, or other electrical components. They mainly consist of a contact body, an insulator, and a housing, and have specific shapes, structures, and interface designs. They can form reliable electrical connections with wires or other terminals through crimping, soldering, and plugging / unplugging. They are key components ensuring the conductivity of electrical connectors and are the core components for achieving electrical connections. Their performance directly affects the stability and reliability of the entire power system. From material selection and structural design to manufacturing processes, optimization is needed based on the electrical, mechanical, and environmental requirements of the application scenario to ensure that the terminals play a crucial role in transmitting current and fixing wires.
[0003] Electromagnetically shielded electrical connector terminals, based on ordinary electrical connector terminals, achieve effective suppression of electromagnetic interference and radio frequency interference through special structural design, material selection, and shielding measures, ensuring signal transmission stability. Their core lies in the deep integration of the terminal's electrical connection function with electromagnetic shielding technology. Suitable for high-end scenarios with extremely high electromagnetic compatibility requirements, the design must ensure the continuity and effectiveness of shielding from the perspectives of materials, structure, and process to meet the stringent anti-interference requirements of modern electronic equipment. In existing structures, gaps appear at the threaded connection when shielding connector terminals at high frequencies, reducing shielding capability. Existing technology has solved this problem through seamless shielding shells. However, with repeated insertion and removal, electromagnetically shielded electrical connector terminals become unstable, the spring elasticity weakens, and the contact pressure decreases, leading to poor contact. Furthermore, the terminals are difficult to remove after installation, making it impossible to replace damaged terminals individually, resulting in the entire component becoming unusable and low maintenance efficiency.

A sealing pressure ring is connected to the top of the outer wall of the fixing ring. A sealing strip is connected to the top of the outer wall of the sealing pressure ring. A sealing pressure ring is connected to the top of the outer wall of the sealing strip. The middle of the outer wall of the fixing ring only contains a sealing component.
[0010] As a further description of the above technical solution:
[0011] The sealing assembly includes a metal screw, and a rotating plate is rotatably connected to the middle of the inner wall of the metal screw.
[0012] As a further description of the above technical solution:

This effectively blocks the intrusion of moisture, dust, and external impurities, preventing them from causing corrosion or short circuit risks to the precision components inside the electrical connector. The metal screw drives the sealing ring to further squeeze the sealing strip, enhancing the fit between the sealing component and the fixing ring, forming a complete shielding cavity. This effectively suppresses electromagnetic wave leakage, isolates external electromagnetic interference, and ensures the stability and accuracy of signal transmission inside the electrical connector.

[0034] Specifically, in the electromagnetic shielded electrical connector terminal, the core component of the disassembly mechanism 2, the round tube 201, is rotatably connected to the bottom of the outer wall of the plug 1 to ensure smooth and stable rotation. A limiting block 202 is fixed to the front side of the bottom of the round tube 201, and limiting plates 203 are symmetrically placed on the left and right sides. A helical spring 204 installed in the middle of the inner wall of the round tube 201 has good resilience and ensures the stability of the mechanism connection.
[0035] The limiting plates 205 on the left and right sides of the bottom of the round tube 201 form a locking structure with the limiting block 202, realizing quick positioning and locking. The bottom of the outer wall of the spring 204 is connected to the disassembly assembly 206.

[0037] Specifically, the sealing structure 3 fixing ring 301 is set in the middle of the outer wall of the shield shell 5, and the top sealing pressure ring 302 of the outer wall of the fixing ring 301 is tightly fitted therein. The sealing pressure ring 302 is used to place the sealing strip 303. When the sealing strip 303 is squeezed, it can fully deform to fill the gap and effectively block the intrusion of external substances such as dust and water vapor.
[0038] The sealing pressure ring 304 is connected to the top of the sealing strip 303 and together with the sealing pressure ring 302, it can firmly press the sealing strip 303 to ensure the reliability of the seal.

The sealing component 305 is provided with a metal screw 3051, and the rotating plate 3052 is rotatably connected to the inner wall of the metal screw 3051 through the central shaft.
[0039] The rotating plate 3052 can rotate flexibly within the metal screw 3051, and can achieve both open and closed states through a specific operating mechanism. In the closed state, the rotating plate 3052 fits tightly against the inner wall of the fixing ring 301, further enhancing the sealing performance. In the open state, it facilitates the inspection and maintenance of the interior of the sealing structure 3, providing a reliable guarantee for the normal operation of the equipment.
[0040] Reference Figure 1 , Figure 2 and Figure 3 The connecting mechanism 4 includes a housing 401, which is rotatably connected to the bottom of the outer wall of the disassembly mechanism 2. A connecting component 402 is fixedly connected to the bottom of the outer wall of the housing 401. The connecting component 402 includes a connecting post 4021, which is located at the bottom of the outer wall of the housing 401. A round shaft 4022 is rotatably connected to the top of the outer wall of the connecting post 4021. Multiple bolts 6 are rotatably connected to the rear side of the middle part of the rotating plate 3052. Nuts 7 are rotatably connected to the bottom of the outer wall of the metal screw 3051. Metal threads 8 are opened on the top of the outer wall of the round tube 201. Anti-slip grooves 9 are fixedly connected around the bottom of the disassembly component 206. Limiting block 1 202 and limiting plate 2 205 are engaged and connected.
[0041] Specifically, in the connecting mechanism 4, the outer shell 401 is rotatably connected to the bottom of the outer wall of the disassembly mechanism 2. At the bottom of the outer wall of the outer shell 401, the connecting component 402 is fixedly connected. The main part of the connecting component 402 is the connecting column 4021, which is vertically set at the bottom of the outer wall of the outer shell 401. At the top of the outer wall of the connecting column 4021, a round shaft 4022 is installed. The round shaft 4022 is rotatably connected to the connecting column 4021, ensuring the smooth rotation of the connecting component 402. Multiple bolts 6 are distributed on the rear side of the middle part of the rotating plate 3052, so that the rotating plate 3052 can be firmly fixed in the corresponding position.
[0042] The bottom of the outer wall of the metal screw 3051 is rotatably connected to the nut 7. The nut 7 and the metal screw 3051 are connected by a standard thread. By rotating the nut 7, the metal screw 3051 can be easily disassembled. The top of the outer wall of the round tube 201 is provided with regular and fine metal threads 8. The bottom of the disassembly component 206 has anti-slip grooves 9 around its perimeter, which increases the friction when in contact with other parts, effectively preventing slippage during disassembly and improving the safety and reliability of the operation.
[0043] Working principle: The electromagnetic shielded electrical connector terminal is equipped with a disassembly mechanism 2, in which the round tube 201 and the limiting block 202 are fixedly connected, and the limiting plate 203 is fixedly connected to the left and right sides of the outer wall of the round tube 201. When the plug 1 needs to be replaced, the bottom rotating shaft 2061 is manually rotated. The rotating shaft 2061 directly drives the connecting tube 2062. At this time, the limiting block 2063 fixed to the connecting tube 2062 rotates accordingly, cooperating with the round tube 201, the limiting block 202, and the limiting plate 203. The limiting block 2063 is engaged inside the limiting plate 203, and the limiting block 2063 is engaged inside the limiting plate 205. 02 is separated, and then the parts to be disassembled are separated from the equipment to complete the disassembly operation. During the process, spring 204 can also assist in reset and buffer the operating force. After quickly replacing plug 1, manually rotate shaft 2061. Connecting tube 2062 and limit block 2063 are driven together. In conjunction with round tube 201, limit block 1 202 and limit plate 1 203, limit block 2063 is locked inside limit plate 1 203. At this time, limit block 1 202 and limit plate 2 205 are also locked together. The various structures cooperate with each other to complete the work. During the installation and disassembly process, spring 204 can assist in reset and buffer the operating force to prevent damage to the parts.
[0044] The electromagnetic shielded electrical connector terminal is equipped with a sealing structure 3, in which a sealing strip 303 is sandwiched between a first sealing ring 302 and a second sealing ring 304. Pressure causes the sealing strip 303 to deform and fill the gap to achieve a seal. The multi-layer ring design can distribute the pressure, allowing the sealing strip 303 to fit more evenly against the sealing surface and improve the sealing effect. The metal screw 3051 transmits force through the screw, causing the sealing ring to further compress the sealing strip 303, making the sealing component 305 fit more tightly against the fixing ring 301, strengthening the sealing pressure, preventing electromagnetic wave leakage, and providing a shielding effect. At the same time, by manually turning the metal screw 3051, the rotating plate 3052 can be rotated around the bolt 6, and the sealing component 305 is unlocked, allowing the sealing material to be replaced in a timely manner.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
