Description

Technical Field

[0001] This invention relates to the field of high-speed connector technology, and in particular to a novel high-speed connector for use in high-speed cables. Background Technology

[0002] High-speed cable connectors are precision connectors used to transmit high-speed digital signals. They establish an electrical signal transmission path by physically connecting conductors through metal contacts (terminals). High-speed cable connectors play a crucial role in data transmission, ensuring that data flow remains consistent and accurate, and maintaining signal integrity even in harsh data-intensive environments.

[0003] Existing high-speed cable connectors are basically made of PCBs (circuit boards), and most PCBs require 8 to 10 layers of wiring process to make, which increases the manufacturing cost and is prone to problems such as excessive impedance and signal crosstalk during high-speed signal transmission. Summary of the Invention

[0004] To address the aforementioned problems in the prior art, this invention provides a novel high-speed connector for use in high-speed cables, comprising an upper terminal assembly, a lower terminal assembly, a primary plastic module, a secondary plastic module, an upper A-type conductive piece, a lower A-type conductive piece, and a B-type conductive piece; The upper terminal assembly and the lower terminal assembly are each composed of several groups of terminals, and each group of terminals consists of a ground terminal and two signal terminals. The aforementioned primary plastic module is a fastener made by injection molding multiple sets of terminals using polyester material through INSERT MOLDING. The upper row of A-type conductive pieces and the upper row of terminal assemblies, and the lower row of A-type conductive pieces and the lower row of terminal assemblies are all fixed by laser welding; The type B conductive piece is arranged between the upper row terminal assembly and the lower row terminal assembly, and the three are assembled by stacking. The secondary plastic module is a fastener that uses polyester material to injection mold the upper terminal assembly, lower terminal assembly, and B-type conductive piece into one piece.

[0005] A further optimized solution: Each of the upper and lower terminal assembly has three cavities at the bottom corresponding to each grounding terminal, with the grounding terminal exposed within these cavities. This cavity structure, specifically designed for the grounding terminal, facilitates post-molding grounding connection processing during INSERT MOLDING.

[0006] A further preferred embodiment: the upper row of A-type conductive pieces is electrically connected to each grounding terminal in the upper row of terminal assemblies, and the lower row of A-type conductive pieces is electrically connected to each grounding terminal in the lower row of terminal assemblies through three conductive points A.

[0007] A further optimized solution: Each grounding terminal on the type B conductive piece is provided with three conductive points B and one conductive point C, all of which are spring-loaded contact points. Conductive points B and C can connect the upper and lower rows of type A conductive pieces in series.

[0008] Further optimized solution: Its manufacturing process includes the following steps: a. Step 1: Arrange one grounding terminal and two signal terminals to form a set of terminals, and arrange several sets of terminals in sequence; b. Step 2: Using polyester material, several groups of terminals are injection molded to form a terminal assembly through INSERT MOLDING, and three cavities are reserved for each grounding terminal during the injection molding process. c. Step 3: Combine the type A conductive piece with the terminal assembly and fix it by laser welding. Also, fix the type A conductive piece with multiple conductive points of the grounding terminal by laser welding, so that all the grounding terminals are connected in series and conductive. d. Step 4: Place the type B conductive piece between the upper and lower terminal assemblies and stack them. At this time, the type B conductive piece can connect the upper and lower type A conductive pieces in series through the conductive point. e: Step 5: Using polyester material, the structure assembled in step 4 is injection molded to finally form a one-piece connector.

[0009] The beneficial effects of this invention are reflected in: First, insert molding is used to fix multiple terminal pairs and form a one-piece connector, making the connector structure more compact and stable.

[0010] Secondly, by superimposing Type A and Type B conductive sheets and connecting them in series with the grounding terminals of the upper and lower terminal assemblies using laser welding, a multi-dimensional anti-interference structure can be formed. Attached Figure Description
