Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a connector for high-frequency shielding. Background Technology

[0002] High-frequency shielded connectors are connectors designed for high-frequency signal transmission and effectively shield against external interference signals. These connectors are typically used for signal transmission in the radio frequency (RF) and microwave bands, and are therefore widely used in wireless communication equipment, antenna systems, and testing equipment. Current high-frequency shielded connectors simply rely on installing shielding components to block interference signals and improve the connector's high-frequency performance. However, the connection between existing shielding components and the high-frequency shielded connector is often weak, prone to loosening and detachment, resulting in insufficient anti-interference performance and signal loss due to shielding issues, thus affecting the transmission performance of high-frequency signals.

The connecting plate is provided with laser welding points, and there are multiple laser welding points, which are arranged at intervals along the length of the connecting plate.

[0007] Preferably, the plastic part has a first through groove and a second through groove, the first terminal group passes through the first through groove and protrudes out of the plastic part, and the second terminal group is inserted and accommodated in the second through groove.

[0023] The present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figures 1 to 6As shown, a connector for high-frequency shielding according to the present invention includes a housing 1, a plastic part 2 disposed on the housing 1, a first terminal group 3 and a second terminal group 4 disposed on the plastic part 2, and a metal cover 5 disposed on the housing 1. The metal cover 5 is detachably connected to the housing 1 to cover an opening at one end of the housing 1. The first terminal group 3 and the second terminal group 4 are arranged in an upper and lower layer relative to the plastic part 2.

[0025] The first terminal group 3 and the second terminal group 4 are arranged in an upper and lower layer relative to the plastic part 2, which does not affect their normal operation and prevents unnecessary interference to data during high-frequency transmission. Furthermore, the metal cover 5 is detachably connected to the housing 1 to cover the opening at one end of the housing 1, facilitating installation and disassembly and effectively compensating for the shielding effect at the opening of the housing 1, thus providing all-around enclosure and shielding. The metal cover 5 is made of a low-resistivity metal material, such as copper or aluminum. High-frequency shielding refers to using the metal cover 5 to block or reduce the propagation of high-frequency electromagnetic waves, thereby preventing electromagnetic interference. The upper and lower layered structure design of the first terminal group 3 and the second terminal group 4 in this invention prevents interference during high-frequency signal transmission, effectively reduces signal loss, and improves the transmission performance of high-frequency signals.

[0026] In this embodiment, the metal cover 5 is provided with an outer wing 51, which extends outward from the outside of the metal cover 5. The outer wing 51 is provided with a slot 52. The housing 1 is provided with an outer edge plate 11, which extends outward from the outside of the housing 1. The outer edge plate 11 is provided with a locking block 12, which protrudes into the slot 52. Specifically, preferably, there are two outer wings 51, which extend outward from both sides of the metal cover 5. The outer wing 51 is provided with a slot 52. Preferably, there are two outer edge plates 11, which extend outward from both sides of the housing 1. The outer edge plate 11 is provided with a locking block 12. When the metal cover 5 covers the opening of the housing 1, the locking block 12 engages with the slot 52, thereby connecting the metal cover 5 and the housing 1, providing both protective and shielding performance.

[0027] In this embodiment, the metal cover 5 is provided with a connecting plate 53. The connecting plate 53 is continuously bent from the top wall of the metal cover 5. The connecting plate 53 is provided with laser welding points 54, and there are multiple laser welding points 54, which are spaced apart along the length of the connecting plate 53. Specifically, the connecting plate 53 is continuously bent from the top wall of the metal cover 5, and the multiple laser welding points 54 are spaced apart along the length of the connecting plate 53, so that an external laser welding device can perform welding and fixing operations on the multiple laser welding points 54, thereby enhancing the connection between the metal cover 5 and the housing 1.

[0028] In this embodiment, the plastic part 2 has a first through groove 21 and a second through groove 22. The first terminal group 3 passes through the first through groove 21 and protrudes out of the plastic part 2. The second terminal group 4 is inserted and accommodated in the second through groove 22. The first terminal group 3 and the second terminal group 4 are staggered along the length direction of the plastic part 2. Specifically, since the first terminal group 3 passes through the first through groove 21 and protrudes out of the plastic part 2, and the second terminal group 4 is inserted and accommodated in the second through groove 22, preferably, the first terminal group 3 has four terminals and the second terminal group 4 has five terminals, so that the first terminal group 3 and the second terminal group 4 are staggered along the length direction of the plastic part 2. Moreover, the front and side surfaces of the first terminal group 3 and the second terminal group 4 are structurally layered to prevent data interference during high-frequency transmission.

[0029] In this embodiment, the inner wall of the housing 1 is provided with an abutment block 13, and the outer wall of the abutment block 13 abuts against the outer wall of the plastic part 2. Specifically, multiple abutment blocks 13 are provided and spaced apart on the inner wall of the housing 1. When the outer wall of the abutment block 13 abuts against the outer wall of the plastic part 2, the position of the plastic part 2 on the housing 1 is limited, and the limiting effect is good.

[0030] The above description is only a preferred embodiment of this utility model.
