Description

Technical Field

[0001] This utility model relates to an electrical connector, specifically an electrical connector with a shielding shell, belonging to the field of electrical connector technology. Background Technology

[0002] Electrical connectors are precision parts, typically used to electrically connect with a pair of terminal connectors to achieve signal transmission. Electrical connectors are widely used in the electronics field. When using USB electrical connectors, a retaining shell is installed on the outer end of the connector to shield and protect it when the connector is mounted on a circuit board.

[0003] However, when using USB connectors, the outer retaining shell is directly stamped from a single piece of metal. Therefore, when cleaning or repairing the inside of the USB connector, the retaining shell can obstruct access to the internal components. Furthermore, the retaining shell is fixed to the circuit board by mounting feet. However, some types of USB connectors require frequent plugging and unplugging, which puts significant stress on the connection between the retaining shell and the circuit board. In particular, some retaining shells have thin feet that cannot provide sufficient gripping force, making them prone to deformation or detachment under frequent plugging and unplugging. This affects the fixation between the USB connector and the circuit board, leading to problems such as poor connection and unstable signal transmission. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical connector with a shielding shell to solve the above problems. It can not only protect and shield the electrical connector, but also facilitate the removal of the first and second fixing shells to clean and maintain the inside of the electrical connector. At the same time, it can also fix the electrical connector to prevent the electrical connector from becoming loose on the circuit board due to repeated plugging and unplugging, which would affect its use.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an electrical connector with a shielding shell, comprising an electrical connector, a shielding structure installed at the outer end of the electrical connector, the shielding structure comprising a first fixed shell and a second fixed shell, the first fixed shell and the second fixed shell being detachably connected to the outer end of the electrical connector, a fixed seat being fixedly connected to the first fixed shell, a fixed sleeve being fixedly connected to the second fixed shell, a fixed rod being fixedly connected to the fixed seat, the fixed rod and the fixed sleeve being inserted into each other, a fixed plate being fixedly connected to the outer ends of both the first fixed shell and the second fixed shell, a telescopic rod being slidably connected inside the fixed plate, and a fixed groove being provided at the other end of the telescopic rod.

[0008] Preferably, a limiting structure is installed on the fixing plate. The limiting structure includes a connecting rod. The bottom end of the fixing plate is slidably connected to the connecting rod. Both ends of the connecting rod are fixedly connected to slide rods. A first locking tooth is fixedly connected to the slide rod, and a second locking tooth is fixedly connected to the telescopic rod. The first locking tooth and the second locking tooth engage.

[0009] Preferably, the first locking tooth has an inverted triangular shape, and the second locking tooth has an equilateral triangular shape.

[0010] Preferably, there are multiple first locking teeth arranged in a linear distribution, and multiple second locking teeth arranged in a linear distribution.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-5 As shown, an electrical connector with a shielding shell includes an electrical connector 1. A shielding structure 2 is installed on the outer end of the electrical connector 1. The shielding structure 2 includes a first fixing shell 201 and a second fixing shell 202. The first fixing shell 201 and the second fixing shell 202 are detachably connected to the outer end of the electrical connector 1. A fixing seat 203 is fixedly connected to the first fixing shell 201. A fixing sleeve 204 is fixedly connected to the second fixing shell 202. A fixing rod 205 is fixedly connected to the fixing seat 203. The fixing rod 205 and the fixing sleeve 204 are inserted into each other. A fixing plate 206 is fixedly connected to the outer end of both the first fixing shell 201 and the second fixing shell 202. A telescopic rod 207 is slidably connected inside the fixing plate 206. A fixing groove 208 is provided at the other end of the telescopic rod 207.

[0024] As a technical optimization of this utility model, a locking block 209 is fixedly connected inside the first fixing shell 201 and the second fixing shell 202. The locking block 209 has an overall inverted triangular shape. An abutting block 210 is fixedly connected inside the first fixing shell 201 and the second fixing shell 202. The side end of the abutting block 210 has an arc-shaped structure. By the locking block 209 and the abutting block 210 engaging, the electrical connector 1 can be limited and fixed.

[0025] As a technical optimization of this utility model, a limiting structure 3 is installed on the fixing plate 206. The limiting structure 3 includes a connecting rod 301. The connecting rod 301 is slidably connected to the bottom end of the fixing plate 206. Sliding rods 302 are fixedly connected to both ends of the connecting rod 301. A first locking tooth 303 is fixedly connected to the sliding rod 302. A second locking tooth 304 is fixedly connected to the telescopic rod 207. The first locking tooth 303 and the second locking tooth 304 engage. The first locking tooth 303 is generally in an inverted triangular shape, and the second locking tooth 304 is generally in an equilateral triangular shape. Multiple first locking teeth 303 and multiple second locking teeth 304 are linearly distributed, thereby enabling adjustment of the telescopic rod 207 and quick limiting and fixing of the telescopic rod 207.

[0026] As a technical optimization of this utility model, a slider 305 is fixedly connected to the top of the telescopic rod 207. The slider 305 is slidably connected to the fixing plate 206. A limiting rod 306 is fixedly connected inside the fixing plate 206. Limiting grooves 307 are provided at both ends of the slider 305. The limiting rod 306 and the limiting grooves 307 are slidably connected. The slider 305 on the telescopic rod 207 can be limited by the limiting rod 306 and the limiting grooves 307, thus limiting the telescopic rod 207.

[0027] As a technical optimization of this utility model, a reset structure 4 is installed on the fixing plate 206. The reset structure 4 includes a mounting base 401. The mounting base 401 is fixedly connected to the top of the fixing plate 206. A pull rod 402 is slidably connected inside the mounting base 401. The bottom end of the pull rod 402 is fixedly connected to the top end of the connecting rod 301. A limiting piece 403 is fixedly connected to the top end of the pull rod 402. The limiting piece 403 is slidably connected to the mounting base 401. A reset spring 404 is fixedly connected between the limiting piece 403 and the mounting base 401. Through the elastic force of the reset spring 404, the limiting piece 403 can be driven to slide and reset. Therefore, the connecting rod 301 is driven to slide and reset by the pull rod 402, so that the first locking tooth 303 and the second locking tooth 304 can be engaged again to limit and fix the telescopic rod 207.

[0028] In use, when the electrical connector 1 needs to be installed on a circuit board, the first fixing shell 201 and the second fixing shell 202 are engaged and installed on the outer end of the electrical connector 1. The connector 1 is fixed and limited by the engagement of the locking block 209 and the abutment block 210. During the engagement, when the fixing rod 205 on the fixing base 203 is inserted into the fixing sleeve 204, it provides support between the first fixing shell 201 and the second fixing shell 202. Then, the sliding rod 302 is pulled down, and the sliding rods 302 at both ends of the fixing plate 206 slide downwards simultaneously through the connecting rod 301. After the first locking tooth 303 and the second locking tooth 304 separate, the length of the telescopic rod 207 is adjusted according to the position of the fixing hole on the circuit board. The slider 305 on the telescopic rod 207 is limited by the limiting rod 306 and the limiting groove 307. Therefore, the telescopic rod 207 can be limited. After adjustment, the slide bar 302 is released, and the spring force of the return spring 404 can drive the limiting piece 403 to slide back. Therefore, the connecting rod 301 is driven to slide back through the pull rod 402, so that the first locking tooth 303 and the second locking tooth 304 can be engaged again to limit and fix the telescopic rod 207. Then, the other telescopic rod 207 is adjusted in the same way. After adjustment, the fixing groove 208 on the telescopic rod 207 can fix the electrical connector 1 again when the circuit board is fixed for use. This not only protects and shields the electrical connector 1, but also makes it easy to remove the first fixing shell 201 and the second fixing shell 202 to clean and repair the inside of the electrical connector 1. At the same time, it can also fix the electrical connector 1 to prevent the electrical connector 1 from becoming loose on the circuit board due to repeated plugging and unplugging, which would affect its use.
