Description
Technical Field
[0001] This utility model relates to the field of connectors, and in particular to a connector with a front-mounted shielding structure. Background Art
[0002] Connectors, also known as plugs or sockets, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. The male and female terminals, upon contact, can transmit information or current, hence the name connector. The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance characteristic is the mechanical life of the connector. Mechanical life is actually a durability indicator, referred to as mechanical operation in the national standard GB5095. It is measured by one insertion and one removal cycle, and the connector's ability to perform its connection function (e.g., contact resistance value) after a specified number of insertion and removal cycles is used as the evaluation criterion.
[0003] To prevent interference from external signals during use, connectors typically employ shielding sheets to block these signals. Existing connector shielding shells are generally located around the outer perimeter of the connector. While this addresses the issue of external signal interference within the connector, it fails to prevent signal interference between the upper and lower layers in double-layer connectors. This negatively impacts signal transmission and user experience. Furthermore, existing shielding shells are attached to the insulating body via a single bent and snapped component. However, due to the larger size of double-layer connectors, a single shielding shell is prone to interference from the insulating body during installation, making the process cumbersome. Therefore, further improvements to the existing connector structure are necessary. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A connector with a front-mounted shielded structure includes an insulating body, terminal groups, and a shielding shell assembly.

[0013] As a preferred option, the second fixing part is provided with a second buckle hole, and the fourth fixing part is integrally provided with a second buckle part that cooperates with the second buckle hole.
[0014] As a preferred option, the first and second shielding components cover the outer surface of the third shielding component.

[0039] Please refer to Figures 1 to 6 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, including an insulating body 10, a terminal group 20, and a shielding shell assembly 30.
[0040] The front end face of the insulating body 10 is integrally recessed with an insertion cavity 101, which is arranged in two layers. The front end face of the insulating body 10 is also integrally recessed with an installation groove 102, which is located between the two layers of insertion cavities 101. In this embodiment, each layer of insertion cavities 101 consists of multiple horizontally spaced insertion cavities, and correspondingly, multiple horizontally spaced installation grooves 102 are also arranged.
[0041] There are multiple terminal groups 20, each terminal group 20 is disposed on the insulating body 10 and extends into the corresponding insertion cavity 101.
[0042] The shielding shell assembly 30 includes a first shielding member 31 and a third shielding member 33. The first shielding member 31 covers the outer periphery of the insulating body 10. The third shielding member 33 is provided with a shielding plate 331 that mates with the mounting groove 102. The third shielding member 33 is disposed on the insulating body 10, and the shielding plate 331 extends into the mounting groove 102 from front to back. The shielding plate 331 can not only shield the interference of signals between the upper and lower layers, but also the front-to-right insertion method makes the assembly process more convenient.
[0043] In this embodiment, the shielding shell assembly 30 further includes a second shielding member 32, with the first shielding member 31 and the second shielding member 32 together covering the outer periphery of the insulating body 10. Compared to existing single shielding shell structures, the structure assembled with the first shielding member 31 and the second shielding member 32 is less susceptible to interference from the insulating body 10 during installation, making the assembly process more convenient. The shielding plates 331 on the third shielding member 33 are also arranged in a plurality of horizontally spaced sections, with each shielding plate 331 extending inward into a corresponding mounting groove 102.
[0044] The first shielding member 31 includes a first main body 311 and a first fixing part 312 and a second fixing part 313 formed by bending the first main body 311 backward. The first main body 311 is attached to the front surface of the insulating body 10; the first fixing part 312 is attached to the upper surface of the insulating body 10; and two second fixing parts 313 are arranged symmetrically on the left and right sides, respectively attached to the left and right side walls of the insulating body 10. A first fixing plate 314 is provided on the first fixing part 312, the front end of which has an upwardly folded first guide part 315, and a first fastening hole 301 is provided on the first fixing plate 314. Multiple first fixing plates 314 are arranged horizontally at intervals. A second fastening hole 302 is provided on the second fixing part 313.
[0045] The second shielding member 32 includes a second main body 321 and a third fixing part 322 and a fourth fixing part 323 integrally bent forward from the second main body 321. The second main body 321 is attached to the rear surface of the insulating body 10, and the third fixing part 322 is attached to the upper surface of the insulating body 10 and fixedly installed together with the first fixing part 312. There are two fourth fixing parts 323 arranged laterally symmetrically, and the two fourth fixing parts 323 are respectively attached to the left and right side walls of the insulating body 10 and fixedly installed together with the corresponding second fixing parts 313. The third fixing part 322 is integrally bent downward to form a second fixing plate 324, so that the second fixing plate 324 is attached to the lower surface of the first fixing plate 314. The second fixing plate 324 is provided with a first fastening part 325 that cooperates with the first fastening hole 301. The third fixing part 322 and the first fixing part 312 are fastened together by the cooperation between the first fastening hole 301 and the first fastening part 325. The second fixing plate 324 is also composed of multiple horizontally spaced first fixing plates 314 and second fixing plates 324, which makes the connection between the first fixing part 312 and the second fixing part 322 more stable. Furthermore, the front end of the second fixing part 322 is provided with multiple horizontally spaced locking plates 326, each with an upwardly folded second guide portion 327 at its front end. Each locking plate 326 is located between two adjacent first fixing plates 314. The upwardly folded second guide portion 327 allows the locking plate 326 to be fitted and locked together with the upper surface of the first fixing part 312. Adjacent locking plates 36 and second fixing plates 324 are respectively fitted and fixed to the upper and lower surfaces of the first fixing part 312, resulting in a better overall fixing effect. The fourth fixing part 323 has an integrally protruding second buckle portion 328 that mates with the second buckle hole 302, allowing the second fixing part 313 and the fourth fixing part 323 to be fastened together through the engagement of the second buckle hole 302 and the second buckle portion 328.
[0046] The third shielding member 33 has a third main body 332. The shielding sheet 331 is integrally formed by bending the third main body 332 backward. Elastic members 333 are formed by bending the third main body 332 backward on both sides. The two elastic members 333 are respectively clamped to the left and right side walls of the insulating body 10. This allows the third shielding member 33 to be fixedly installed on the insulating body 10 by the two elastic members 333. The first shielding member 31 and the second shielding member 32 cover the outer surface of the third shielding member 33. This allows the position of the third shielding member 33 to be further fixed by the first shielding member 31 and the second shielding member 32.
[0047] The key design feature of this invention is that the front end face of the insulating body is integrally recessed with an inwardly recessed mounting groove, which is located between the upper and lower insertion cavities. The third shielding component is provided with a shielding sheet that mates with the mounting groove. The third shielding component is disposed on the insulating body, and the shielding sheet extends into the mounting groove from front to back. This not only enables signal shielding between the upper and lower connectors through the shielding sheet, ensuring the signal transmission process and providing a better user experience, but also simplifies the assembly process due to the front-insertion structure.
[0048] Together with the first and second shielding components, they cover the outer periphery of the insulating body. This allows the covering process of the insulating body to be completed through the assembly of the two shielding components. Even if the insulating body is too large, interference between the shielding components and the insulating body can be avoided during assembly, making the installation process more convenient.
[0049] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
