Description

Technical Field

[0001] The invention relates to the technology of connector field, in particular to a connector with a light-emitting structure. Background Art

[0002] Connectors are also called connectors. In China, they are also called joints and sockets, and generally refer to electrical connectors. That is, a device that connects two active devices to transmit current or signals. The male end and the female end can transmit information or current after contact, and are also called connectors. The basic performance of connectors can be divided into three categories: mechanical performance, electrical performance, and environmental performance. Another important mechanical performance is the mechanical life of the connector. Mechanical life is actually a durability indicator, which is called mechanical operation in the national standard GB5095. It is based on one insertion and one removal as a cycle, and whether the connector can normally complete its connection function (such as contact resistance value) after the specified insertion and removal cycle is used as the basis for judgment.

[0003] During the use of the connector, in order to facilitate users to observe the working status of the connector, a light-emitting component is added to the connector to judge its working status by the difference in brightness; there are two positions for the light, one is on the side of the plug interface, and the other is window lighting.

[0004] The window emits light by setting a light-emitting component behind the window and emitting the light through a crystal head. In the upper and lower double-layer connector, it is necessary to set light-emitting components behind the upper and lower windows respectively. The setting of two light-emitting components will make the overall structure more complicated. During the assembly process, the two light-emitting components need to be assembled separately, which makes the assembly process more troublesome. At the same time, the existing double-layer connector cannot solve the signal interference problem between the upper and lower layers, thereby affecting the signal transmission process of the double-layer connector and affecting the user's experience. In addition, the existing shielding shell is buckled on the insulating body by bending and buckling a single part, but due to the large size of the double-layer connector, the single shielding shell is easily interfered by the insulating body during the installation process, resulting in a troublesome installation process. Therefore, it is necessary to make further improvements to the existing connector structure. Summary of the invention

[0055] The front end surface of the insulating body 10 is integrally provided with an insertion cavity 101 which is arranged in two layers, and the front end surface of the insulating body 10 is also integrally provided with an installation groove 102 which is located between the upper and lower layers of the insertion cavity 101. In this embodiment, each layer of the insertion cavity 101 is arranged in a plurality of lateral intervals. The insulating body 10 is provided with a third PCB board 11, a filter 12 and a second connection terminal 13. The filter 12 is arranged on the third PCB board 11 and connected to the third PCB board 11. One end of the second connection terminal 13 is connected to the third PCB board 11, and the other end of the second connection terminal 13 extends outward from the insulating body 10 and is connected to the external first PCB board 50. The filter 13 is used to filter the signal transmitted by the terminal group 20, thereby ensuring the quality of signal transmission. The structure of the built-in filter 12 makes it unnecessary to install a separate filter when welding and installing with the external PCB board 50, thereby facilitating its use and installation process. A mounting seat 14 is provided in the insertion cavity 101. The insulating body 10 has a rear end formed with a mounting cavity 103 communicating with the insertion cavity 101 . The third PCB board 11 , the filter 12 and the second connection terminal 13 are disposed in the mounting cavity 103 .

[0056] The terminal group 20 is provided in multiple configurations, and the contact portion 21 of each terminal group 20 extends into the corresponding insertion cavity 101, and the welding portion 22 of each terminal group 20 is connected to the external first PCB board 50; in this embodiment, a corresponding terminal group 20 is provided in each insertion cavity 101; the welding end 22 of the terminal group 20 is connected to the third PCB board 11. The terminal group 20 is embedded in the mounting seat 14.

[0057] The integrated light emitting structure 30 is arranged on the insulating body 10 and located at the rear end of the corresponding upper and lower insertion cavities 101. The integrated light emitting structure 30 includes a mounting plate 31, a second PCB board 32, a light source 33 and a connecting terminal 34. The mounting plate 31 is arranged in the insulating body 10 and located at the rear end of the insertion cavity 101. The second PCB board 32 is provided in two sets, and the two second PCB boards 32 are arranged on the mounting plate 31 with an interval up and down. The light source 33 is arranged in two sets up and down, and the two light sources 33 are respectively connected to the corresponding second PCB board 32 and correspond to the position of the corresponding light guide plate 11, so as to ensure that the light emitted by the light source 33 can be emitted outward through the light guide plate 11. The connecting terminal 34 is provided in two groups, and one end of each group of connecting terminals 34 is respectively connected to the corresponding second PCB board 32, and the other end extends outward from the insulating body 10 and is connected to the external first PCB board 50. In this embodiment, the integrated light emitting structure 30 is a plurality of light emitting structures arranged in a horizontal interval.

[0058] The second PCB board 32 is provided with two mounting holes 301 arranged in a horizontal interval. The mounting board 31 integrally extends forward with mounting posts 311 corresponding to the mounting holes 301. The second PCB board 32 is arranged on the mounting board 31 through the cooperation between the mounting holes 301 and the mounting posts 311. A limiting plate 35 is arranged on the mounting board 31. The lower end of the connecting terminal 34 is embedded in the mounting board 35 and extends downward from the limiting plate 35. The limiting plate 35 is used to limit and fix the lower end of the terminal group 34, thereby ensuring the overall structural strength. The aforementioned mounting posts 311 are integrally extended forward from the front side of the limiting plate 35. The second PCB board 32 located below is installed on the limiting plate 35 through the cooperation between the mounting holes 301 and the mounting posts 311. The front side wall of the mounting plate 31 is integrally recessed with a groove 302 extending up and down, and the depth of the groove 302 is greater than the thickness of the connecting terminal 34; the connecting terminal 34 is located in the groove 302, so that the connecting terminal 34 can be hidden in the groove 302, which can not only protect the connecting terminal 34, but also make the overall integrity stronger and more convenient for its assembly process. The lower ends of the two groups of connecting terminals 34 extend downward from the mounting plate 31 in a front-to-back arrangement, avoiding too many connecting terminals 34 in the same row, increasing the spacing between adjacent connecting terminals 34, and reducing the risk of short circuit. After the mounting seat 14 is installed together with the mounting plate 31 and the third PCB board 11, it is loaded into the corresponding mounting cavity 103 and the insertion cavity 101 from the rear end of the mounting cavity 103 from the back to the front, so that it is first assembled externally and then assembled with the insulating body 10, and the assembly process is also more convenient.

The third shielding member 43 is provided on the insulating body 10, and the shielding sheet 431 extends inwardly from the front to the back into the mounting groove 102. The shielding sheet 431 can not only shield the interference of the signals between the upper and lower layers, but also the assembly process is more convenient due to the front-to-back plug-in method.

[0060] In this embodiment, the shielding pieces 431 on the third shielding member 43 are also arranged in a plurality of spaces in a transverse direction, and each shielding piece 431 extends inwardly into the corresponding mounting groove 102. The shielding shell assembly 40 also includes a second shielding member 42, and the first shielding member 41 and the second shielding member 42 are jointly covered on the outer periphery of the insulating body 10. Compared with the existing single shielding shell structure, the structure assembled and covered by the first shielding member 41 and the second shielding member 42 is not easily interfered by the insulating body 10 during the installation process, and the assembly process is more convenient;

The fourth fixing portion 423 is arranged in two symmetrical positions in the transverse direction, and the two fourth fixing portions 423 are respectively attached to the left and right side walls of the insulating body 10 and fixedly installed with the corresponding second fixing portion 413. A second fixing plate 424 is integrally bent downward from the third fixing portion 422, so that the second fixing plate 424 is attached to the lower surface of the first fixing plate 414. A first buckle 425 that matches the first buckle hole 401 is provided on the second fixing plate 424, and the third fixing portion 422 and the first fixing portion 412 are fixed together by the matching buckle between the first buckle hole 401 and the first buckle 425. The second fixing plate 424 is also arranged in multiple lateral intervals. The multiple first fixing plates 414 and the second fixing plates 424 can make the connection between the first fixing part 412 and the second fixing part 422 more stable.

The front end of the locking plate 426 has a second guide portion 427 that is folded upward. Each locking plate 426 is located between two adjacent first fixing plates 414. Through the second guide portion 427 that is folded upward, the locking plate 426 is fitted and locked with the upper surface of the first fixing part 412. The adjacent locking plates 36 and the second fixing plates 424 are respectively fitted and fixed on the upper and lower surfaces of the first fixing part 412. This makes the overall fixing effect better. The fourth fixing part 423 is integrally provided with a second buckle 428 that matches the second buckle hole 402, so that the second fixing part 413 and the fourth fixing part 423 are fixed together through the second buckle hole 402 and the second buckle 428.

The third shielding component is provided with a shielding sheet that cooperates with the installation groove, and the shielding sheet extends into the installation groove from front to back, so that not only can the shielding sheet be used to shield the signals between the upper and lower connectors, thereby ensuring the signal transmission process and providing a better user experience, but the front-insertion structure also makes the assembly process simpler; and the first shielding component and the second shielding component are jointly coated on the outer periphery of the insulating body; the coating process of the insulating body is completed by assembling the two shielding component structures, and even if the insulating body is too large, interference with the insulating body can be avoided during assembly, further making the installation process more convenient.
