Description

Technical Field

[0001] This utility model belongs to the field of connector technology, and particularly relates to socket backplate connectors. Background Technology

[0002] A backplane connector is a device used to provide a stable electrical connection between multiple circuit boards. The purpose of a backplane connector is to connect multiple daughter boards on a main circuit board (backplane) to transmit high-speed differential or single-ended signals as well as large currents.

[0003] The backplane connector has multiple transmission channels in its terminal assembly and connects to external devices through the connection terminals of the terminal assembly. During use, two adjacent transmission channels may transmit the same or different data or current, causing the differential signal terminals to interfere with each other, reducing the signal transmission stability and the electromagnetic compatibility of the system. Utility Model Content

[0004] This invention addresses the problem in existing technologies where adjacent transmission channels interfere with each other, reducing signal transmission stability and system electromagnetic compatibility due to the transmission of the same or different data or current. The following technical solution is proposed:

[0005] A socket backplate connector includes: a terminal assembly and a terminal insulating component fixedly connected to the terminal assembly. The terminal assembly head is provided with multiple sets of connection terminals. The same set of connection terminals is divided into ground terminals and differential signal terminals. Both sides of the terminal assembly end are provided with outer shielding plates. One of the outer shielding plates is located at the differential signal terminal position and has multiple sets of through holes. Multiple sets of inner shielding plates are provided between two outer shielding plates.

[0006] There are two inner shielding sheets in the same group, and the two inner shielding sheets are located on both sides of the differential signal terminals of the same group of connection terminals.

[0007] As a preferred embodiment of the above technical solution, a first insert block is provided on both sides of one end of the inner shielding sheet, a corresponding first slot is provided on the surface of each of the two outer shielding sheets, a second insert block is provided on the other end of the inner shielding sheet, and a corresponding second slot is provided on the surface of the terminal assembly.

[0008] As a preferred embodiment of the above technical solution, it further includes: a base, wherein a plurality of the terminal assemblies are inserted into the base and fixedly connected to the base by screws or other fasteners.

[0009] As a preferred embodiment of the above technical solution, it further includes: a fixing frame, wherein the fixing frame is used to fix multiple terminal assemblies to prevent the terminal assemblies from loosening by means of terminal insulating components.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. When used together with the outer shield, the two inner shields form a covered shielding space, which can isolate the differential signal terminals in two adjacent groups. When in use, the inner and outer shields are grounded, which can shield the differential signal terminals of different groups to prevent mutual interference, reduce common-mode noise, improve the anti-interference ability of the signal, reduce signal reflection and loss, effectively reduce electromagnetic interference, and improve the electromagnetic compatibility of the system.

[0012] 2. The inner shielding plate and the terminal assembly are inserted and matched with the outer shielding plate, which can restrict the position of the inner shielding plate and prevent displacement during use, thus preventing the formation of a full-coverage shielding space. In addition, the inner shielding plate can effectively strengthen the connection between the outer shielding plate and the base, making the connector more stable. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings.

[0018] Example

[0019] Figures 1-3 The socket backplate connector includes: a terminal assembly 10 and a terminal insulator 30 fixedly connected to the terminal assembly 10. The terminal assembly 10 has multiple sets of connection terminals 11 at its head. Each set of connection terminals 11 is divided into a ground terminal 111 and a differential signal terminal 112. Both sides of the terminal assembly 10 are provided with an outer shield 21. One of the outer shields 21 is located at the differential signal terminal 112 and has multiple sets of through holes. The through holes in the outer shield 21 at the differential signal terminal 112 can adjust the capacitive coupling between the shield and the differential signal line, helping to maintain or optimize the characteristic impedance of the differential pair. Multiple sets of inner shields 22 are provided between the two outer shields 21.

[0020] There are two inner shielding plates 22 in the same group, and the two inner shielding plates 22 are located on both sides of the differential signal terminals 112 of the same group of connection terminals 11.

[0021] When the two inner shielding plates 22 are used together with the outer shielding plate 21, they form an enclosed shielding space, which can isolate the differential signal terminals 112 in two adjacent groups. When in use, the inner shielding plate 22 and the outer shielding plate 21 are grounded, which can shield the differential signal terminals 112 in different groups to prevent mutual interference, reduce common-mode noise, improve the anti-interference ability of the signal, reduce signal reflection and loss, effectively reduce electromagnetic interference, and improve the electromagnetic compatibility of the system.

[0022] Figures 2-3 In this design, the inner shielding sheet 22 has a first insert 221 on both sides of one end, and the two outer shielding sheets 21 have corresponding first slots 222 on their surfaces. The inner shielding sheet 22 has a second insert 223 on its other end, and the terminal assembly 10 has a corresponding second slot 224 on its surface. After the inner shielding sheet 22 is installed, it can be fixed with screws or other fasteners to prevent displacement of the inner shielding sheet 22.

[0023] The inner shield 22 is inserted and engaged with the terminal assembly 10 and the outer shield 21, which can restrict the position of the inner shield 22 and prevent displacement during use, thus preventing the formation of a full-coverage shielding space. In addition, the inner shield 22 can effectively strengthen the connection between the outer shield 21 and the base 40, making the connector more stable.

[0024] Figure 1 The system also includes a base 40, and a plurality of terminal assemblies 10 are inserted into the base 40 and fixedly connected to the base 40 by screws or other fasteners.

[0025] The base 40 typically secures the terminal assembly 10 in place with screws or other fasteners, ensuring that the terminals will not loosen or shift even under vibration or movement, thus ensuring safe and reliable power transmission.

[0026] Figure 1 The device also includes a fixing frame 50, which uses a terminal insulating member 30 to fix multiple terminal assemblies 10 to prevent the terminal assemblies 10 from loosening.

[0027] The mounting bracket 50, through the terminal insulator 30, is used to fix multiple terminal assemblies 10 to prevent the terminal assemblies 10 from loosening, and to fix the other end of the connector. In conjunction with the base 40, it improves the overall stability and reliability of the connector.

[0028] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
