Description

Technical Field

[0001] This utility model relates to the field of high-voltage connectors, and in particular to a grounding shielding structure for an on-board data connector. Background Technology

[0002] Automotive connectors are key components for in-vehicle signal transmission, widely used in automotive imaging systems, detection systems, and driver assistance systems. The shielding and grounding system of automotive Ethernet connectors is a crucial structural system for ensuring signal integrity. Current mainstream shielding solutions have significant drawbacks: First, the overall metal casing shielding solution relies on surface-to-surface contact between the plug and socket metal casings for conduction, requiring extremely high assembly precision. Vehicle vibration and temperature changes can easily cause contact gaps, increasing resistance and reducing shielding effectiveness over long-term use. Second, the wire grounding solution, which constructs a path by welding or crimping wires, is prone to solder joint cracking and wire detachment due to vibration, and the parasitic inductance of the wires can interfere with high-frequency transmission. Third, the elastic contact piece solution is mostly single-point contact with low redundancy; failure results in immediate disconnection, and the contact pieces are fixed with screws or glue, a cumbersome process or prone to detachment at high temperatures. Therefore, a new solution is urgently needed to address these problems. Utility Model Content

[0004] The socket connector is provided with a shielded contact portion;

[0005] One end of the plug connector is electrically connected to the shielding layer of the cable, and the other end is detachably connected to the socket connector;

[0006] The shielding connector includes a body and elastic contact portions disposed on both sides of the body. The body engages with the plug connector, and the elastic contact portions abut against the shielding contact portions.

[0007] The socket connector has a first protrusion on its lower surface, and the plug connector has a first opening that fits onto the first protrusion.

[0008] The plug connector has opposing claws that clamp the socket connector from both sides.

[0009] One end of the plug connector is a cylindrical crimping part, which is crimped onto the shielding layer of the cable.

[0010] The socket connector has a second protrusion on its upper surface, the plug connector has snap-fit ​​protrusions on both sides, the shielding connector has a second opening and a snap-fit ​​on both sides, the second opening is fitted with the second protrusion, and the snap-fit ​​is engaged with the snap-fit ​​protrusion.

[0011] One end of the elastic contact portion is connected to the body, and the other end is a free end. The free end has a curved portion, and the curved surface of the curved portion abuts against the shielding contact portion.

[0012] The number of elastic contact portions is multiple, and they are distributed at intervals along the side of the body.

[0013] It also includes a housing, in which the socket connector is located, and the housing has a card interface through which the plug connector extends into the housing.

[0037] One end of the plug connector 2 is a cylindrical crimping part 23, which is crimped onto the shielding layer of the cable 5.

[0038] The upper surface of the socket connector 1 has a second protrusion 13, such as Figure 2 As shown, the plug connector 2 has snap-fit ​​protrusions 24 on both sides, and the shielding connector 3 has a second opening 33 and a latch 34 on both sides. The second opening 33 is fitted with the second protrusion 13, and the latch 34 is snapped with the snap-fit ​​protrusion 24.

[0039] One end of the elastic contact portion 32 is connected to the body 31, and the other end is a free end. The free end has a bent portion 321, and the bent surface of the bent portion 321 abuts against the shielding contact portion 11.

[0040] The number of elastic contact portions 32 is multiple, and they are distributed at intervals along the side of the body 31.

[0041] It also includes a housing 4, the socket connector 1 is located inside the housing 4, the housing 4 has a card interface 41, and the plug connector 2 extends into the housing 4 through the card interface 41.

[0042] Furthermore, the outer casing 4 has a receiving groove 42, such as Figure 5 As shown, the shielding contact part 11 is disposed in the receiving groove 42.

[0043] Furthermore, the shielding contact portion 11 has locking points 111 at both ends, such as... Figure 6 As shown, the receiving groove 42 has slots 421 at both ends, and the locking point 111 cooperates with the slots 421 to fix the shielding contact part 11 in the receiving groove 42.

[0044] The vehicle data connector grounding and shielding structure provided in this embodiment aims to solve the problem of electromagnetic interference in data transmission in the vehicle environment, achieving stable grounding and shielding effects through the coordinated operation of multiple components. The outer casing 4 has a card interface 41 for the plug connector 2 to extend from the outside and mate with the internal socket connector 1. The size of the card interface 41 is adapted to the plug connector 2. An internal receiving groove 42 is located inside the outer casing 4 at the position corresponding to the socket connector 1, used to place the shielding contact part 11 of the socket connector 1. Both ends of the receiving groove 42 have protruding card slots 421, such as... Figure 6 As shown, the locking point 111 of the shielding contact part 11 cooperates with the locking point 111 to fix the shielding contact part 11 and prevent it from shifting due to vibration during vehicle operation.

[0045] The socket connector 1 is fixed inside the housing 4, serving as a connection intermediary between the plug connector 2 and the vehicle-mounted equipment. Its lower surface has a first protrusion 12, which is cylindrical or rectangular, and engages with the first opening 21 of the plug connector 2 to prevent misalignment when the plug connector 2 and socket connector 1 mate. The upper surface has a second protrusion 13, whose shape matches the first protrusion 12, and is used to mate with the second opening 33 of the shielding connector 3 to achieve the positioning and installation of the shielding connector 3.

[0046] The shielding contact part 11 is made of a shielding material with excellent conductivity. One end is electrically connected to the grounding terminal of the vehicle equipment, and the other end is exposed in the receiving groove 42, serving as a contact carrier with the shielding connector 3.

[0047] The plug connector 2 has a first opening 21 located at the end of the plug connector 2 closest to the socket connector 1, which fits onto the first protrusion 12 of the socket connector 1 for positioning. Claws 22 are provided on both sides. When the socket connector 1 and plug connector 2 mate, the claws 22 clamp the side walls of the socket connector 1 from both sides, forming a detachable and secure connection, while enhancing the structural stability after mating and preventing detachment due to vehicle vibration. Snap-fit ​​protrusions 24 are also provided on both sides, used to engage with the snap-fit ​​34 of the shielding connector 3 to achieve snap-fit ​​fixation between the shielding connector 3 and the plug connector 2. A cylindrical crimping part 23 is provided at the end of the plug connector 2 furthest from the socket connector 1. The inner diameter of the cylindrical structure matches the outer diameter of the cable 5.

Multiple elastic contact portions 32 are provided on both sides of the body 31, the number of which can be adjusted according to shielding requirements. They are evenly spaced along the sides of the body 31 to ensure uniform contact. One end of the elastic contact portion 32 is fixedly connected to the body 31, and the other end is a free end, which is bent towards the shielding contact portion 11 to form a bent portion 321. The arc-shaped surface of the bent portion 321 tightly abuts against the shielding contact portion 11, using elastic deformation to compensate for installation errors and vibration gaps, ensuring continuous electrical connection.

[0049] When plug connector 2 mates with socket connector 1, all components form a complete grounding shielding path. The shielding layer of cable 5 is electrically connected through the crimping part 23 of plug connector 2, guiding electromagnetic interference from cable 5 into plug connector 2. Plug connector 2 is fixed to the bayonet 34 of shielding connector 3 via snap-fit ​​protrusion 24, transmitting interference signals to shielding connector 3. The elastic contact part 32 of shielding connector 3 abuts against the shielding contact part 11 of socket connector 1 via bending part 321, transmitting interference signals to shielding contact part 11. Shielding contact part 11 connects to the grounding terminal of the vehicle equipment, ultimately guiding electromagnetic interference to the ground, thus achieving shielding protection for the vehicle data connector.
