Description

Technical Field

[0001] This utility model relates to the field of connectors, and in particular to a double-layer connector with an integrated light-emitting structure. Background Technology

[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] During the use of connectors, in order to facilitate users to observe the working status of the connectors, light-emitting components are added to the connectors, and the working status is judged by the different brightness. There are two types of light-emitting positions: one is on the side of the interface, and the other is the window light-emitting method.

[0004] The window emits light by placing a light-emitting component behind the window and radiating the light through a crystal head. In a double-layer connector, light-emitting components need to be placed behind both the upper and lower layers of the window. This dual-component design complicates the overall structure, requiring separate assembly of each component, which is cumbersome and reduces assembly efficiency. Therefore, it is necessary to further improve the existing connector structure. Utility Model Content

[0005] In view of this, the present invention addresses the deficiencies of the existing technology, and its main objective is to provide a double-layer connector with an integrated light-emitting structure, which can effectively solve the problems of complex structure, cumbersome assembly process, and low assembly efficiency of existing window-emitting double-layer connectors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A double-layer connector with an integrated light-emitting structure includes an insulating body and terminal groups. The insulating body has an inwardly recessed insertion cavity at its front end, arranged in two layers, with a light guide plate on the rear sidewall of the insertion cavity. Multiple terminal groups are embedded in the insulating body, with the contact portion of each terminal group extending into the corresponding insertion cavity, and the soldering portion of each terminal group extending outward from the insulating body and soldered to an external first PCB board. The connector is characterized by further including an integrated light-emitting structure disposed on the insulating body and located on the corresponding upper and lower insertion cavities. At the rear end of the cavity, the integrated light-emitting structure includes a mounting plate, a second PCB board, a light source, and connecting terminals. The mounting plate is disposed in the insulating body and located at the rear end of the cavity. There are two second PCB boards, which are arranged vertically on the mounting plate with a gap between them. There are two light sources arranged vertically, and each light source is connected to the corresponding second PCB board and corresponds to the position of the corresponding light guide plate. There are two sets of connecting terminals, one end of which is connected to the corresponding second PCB board, and the other end extends outward from the insulating body and connects to the external first PCB board.

[0008] As a preferred option, each layer of insertion cavities consists of multiple horizontally spaced cavities, and each insertion cavity is equipped with a corresponding terminal group; correspondingly, the integrated light-emitting structure consists of multiple horizontally spaced cavities.

[0009] As a preferred option, the second PCB board has two horizontally spaced mounting holes, and the mounting plate extends forward integrally with mounting posts corresponding to the mounting holes. The second PCB board is mounted on the mounting plate through the cooperation of the mounting holes and the mounting posts.

[0010] As a preferred option, the mounting plate is provided with a limiting plate, and the lower end of the connecting terminal is embedded in the mounting plate and extends downward out of the limiting plate.

[0011] As a preferred option, the aforementioned mounting post extends forward integrally from the front side of the limiting plate, and the second PCB board located below is mounted on the limiting plate through the cooperation of the mounting hole and the mounting post.

[0012] As a preferred embodiment, the front sidewall of the mounting plate is integrally recessed with a groove extending vertically, and the depth of the groove is greater than the thickness of the connecting terminal; the connecting terminal is located in the groove.

[0013] As a preferred option, the lower ends of the two sets of connection terminals extend downwards from the mounting plate in a front-to-back arrangement.

[0014] As a preferred option, a shielding shell is also included; the shielding shell is fitted around the periphery of the insulating body.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution:

[0016] It features an integrated light-emitting structure mounted on an insulating body at the rear end of the corresponding upper and lower insertion cavities. This integrated light-emitting structure includes a mounting plate, a second PCB board, a light source, and connecting terminals. Two light sources are arranged vertically, each connected to its corresponding second PCB board and positioned with a corresponding light guide plate. This modular design allows for the illumination of both upper and lower insertion cavities with a single light-emitting structure, eliminating the need for two separate light-emitting components. This simplifies the overall structure and simplifies assembly, requiring only one light-emitting structure to be assembled, significantly improving assembly efficiency.

[0032] Please refer to Figures 1 to 4 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which includes an insulating body 10, a terminal group 20, an integrated light-emitting structure 30, and a shielding shell 40.

[0033] The insulating body 10 has an inwardly recessed insertion cavity 101 at its front end. The insertion cavity 101 is arranged in two layers, and a light guide plate 11 is provided on the rear side wall of the insertion cavity 101. The light guide plate 11 is used to conduct the light emitted by the integrated light-emitting structure 30. In this embodiment, each layer of insertion cavities 101 consists of multiple cavities arranged horizontally at intervals.

[0034] The terminal group 20 is configured in multiple ways, and each terminal group 20 is embedded in the insulating body 10. The contact portion 21 of each terminal group 20 extends into the corresponding insertion cavity 101, and the welding portion of each terminal group 20 extends outward from the insulating body 10 and is welded together with the external first PCB board 50. In this embodiment, each insertion cavity 101 is provided with a corresponding terminal group 20.

[0035] The integrated light-emitting structure 30 is disposed 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 connecting terminals 34. The mounting plate 31 is disposed in the insulating body 10 and located at the rear end of the insertion cavity 101. Two second PCB boards 32 are disposed, arranged vertically and alternately on the mounting plate 31. Two light sources 33 are arranged vertically, each connected to a corresponding second PCB board 32 and corresponding to a light guide plate 11, thereby ensuring that the light emitted by the light source 33 can be emitted outward through the light guide plate 11. Two sets of connecting terminals 34 are disposed, with one end of each set connected to a corresponding second PCB board 32, and the other end extending outward from the insulating body 10 and connected to the external first PCB board 50. In this embodiment, multiple integrated light-emitting structures 30 are arranged horizontally at intervals.

[0036] The second PCB board 32 has two horizontally spaced mounting holes 301. The mounting plate 31 integrally extends forward with mounting posts 311 corresponding to the mounting holes 301. The second PCB board 32 is mounted on the mounting plate 31 through the cooperation of the mounting holes 301 and the mounting posts 311. A limiting plate 35 is provided on the mounting plate 31. The lower end of the connecting terminal 34 is embedded in the mounting plate 35 and extends downward beyond the limiting plate 35. This limiting plate 35 is used to limit and fix the lower end of the terminal group 34, ensuring the overall structural strength. The aforementioned mounting posts 311 integrally extend forward from the front side of the limiting plate 35. The second PCB board 32, located below, is mounted on the limiting plate 35 through the cooperation of the mounting holes 301 and the mounting posts 311. The mounting plate 31 has an integrally recessed groove 302 extending vertically on its front sidewall, 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, allowing it to be concealed within the groove. This not only protects the connecting terminal 34 but also enhances the overall integrity and facilitates assembly. The lower ends of the two sets of connecting terminals 34 extend downwards from the mounting plate 31 in a front-to-back arrangement, avoiding an excessive number of connecting terminals 34 in the same row, increasing the spacing between adjacent connecting terminals 34, and reducing the risk of short circuits.

[0037] The shielding shell 40 is fitted around the periphery of the insulating body 10. The shielding shell 40 is used to shield the connector and prevent it from being interfered with by external signals during operation.

[0038] The key design feature of this invention is that it incorporates an integrated light-emitting structure, which is mounted on an insulating body and located at the rear end of the corresponding upper and lower insertion cavities. This integrated light-emitting structure includes a mounting plate, a second PCB board, a light source, and connecting terminals. Two light sources are arranged vertically, each connected to its corresponding second PCB board and positioned with a corresponding light guide plate. This modular design allows for the illumination of both upper and lower insertion cavities with a single light-emitting structure, eliminating the need for two separate light-emitting components. This simplifies the overall structure and simplifies assembly, requiring only one light-emitting structure to be assembled, significantly improving assembly efficiency.

[0039] 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.
