Description

Technical Field

[0001] This utility model relates to the field of connector connection and installation technology, and in particular to a cable and connector installation and connection structure. Background Technology

[0002] High-frequency, high-speed cables are specialized cables designed for transmitting high-frequency signals (typically exceeding 1 GHz) and high-speed data (rates reaching tens of Gbps or even higher). They are widely used in communications, data centers, consumer electronics, automotive electronics, and other fields. Their core objective is to maintain signal integrity in high-frequency environments, reducing attenuation, crosstalk, and latency to meet the stringent requirements of modern electronic systems for data transmission speed and reliability.

[0003] With the development of high-speed and high-frequency cables, high-frequency characteristics have become a crucial indicator for these cables, and the requirements for these characteristics are becoming increasingly stringent. Conventional MCIO, Multi-Track, and other product cable male connectors, after being soldered to high-speed and high-frequency cables, typically employ an inner mold forming method to create an inner mold at the connector's tail end. This inner mold completely covers the internal space of the connector, thus securing the high-speed and high-frequency cable to the solder joints on the PCB. However, this method of forming the inner mold fills the connector's interior, completely covering the exposed wire cores and PCB solder joint surfaces after stripping, significantly negatively impacting high-frequency electrical characteristics and leading to decreased signal transmission stability and reliability. Therefore, it is necessary to research a solution to address these issues. Utility Model Content

The front and rear end faces of the main body 131 form the aforementioned plurality of wire holes 102, which are arranged in two rows. The extension 132 extends rearward integrally from the rear end face of the main body 131. The extension 132 is embedded and fixed together with the inner membrane body 14.

In addition, two undercut grooves 106 are recessed on both sides of the wire clamp 13. The undercut grooves 106 are embedded in the inner membrane 14. There are two undercut grooves 106, which are located on the left and right sides of the main body 131 respectively. Moreover, fixing holes 107 are provided on both the upper and lower surfaces of the insulating body 11. The fixing holes 107 communicate with the first mounting cavity 101 and are embedded in the inner membrane 14, so that the inner membrane 14 and the insulating body 11 are more firmly attached and not easily separated.

[0037] The cable 20 is electrically connected to the connector 10. Specifically, the cable 20 includes multiple high-speed wires 21, which are respectively adapted to and attached to multiple through holes 102 and inserted into the multiple through holes 102 from back to front. The front ends of the multiple high-speed wires 21 are all soldered to the first PCB 12 for conduction, and the multiple high-speed wires 21 are all embedded and fixed together with the inner mold body 14. In this embodiment, the multiple high-speed wires 21 are arranged in two rows, and the multiple high-speed wires 21 are respectively embedded in multiple wire grooves 103.

[0038] Furthermore, the first mounting cavity 101 consists of two parallel and interconnected cavities. Each first mounting cavity 101 is provided with a first PCB 12. Each first PCB 12 is provided with a wire clamp 13. Each wire clamp 13 clamps and fixes multiple high-speed wires 21. Each wire clamp 13 is embedded and fixed together with the inner membrane body 14.

[0039] In addition, the insulating body 11 has a second mounting cavity 108 with a rearward opening.

A second PCB 15 is disposed in the second mounting cavity 108. The second PCB 15 is inserted into the second mounting cavity 108 from back to front. The front end of the second PCB 15 is exposed at the front end of the insulating body 11. A fixing plug 16 is disposed in the opening of the second mounting cavity 108. The fixing plug 16 is located behind the second PCB 15. The outer peripheral side of the fixing plug 16 fits against the inner peripheral side of the second mounting cavity 108. The fixing plug 16 is embedded and fixed together with the inner membrane body 14.

[0040] The cable 20 includes multiple power cables 22 and multiple low-speed cables 23. The multiple power cables 22 and multiple low-speed cables 23 pass through the fixing plug 16 from back to front. The front ends of the multiple power cables 22 and multiple low-speed cables 23 are soldered to the second PCB 15 for conduction. The multiple power cables 22 and multiple low-speed cables 23 are embedded and fixed together with the inner membrane body 14.

[0041] The assembly process of this embodiment is described in detail below:

[0042] First, multiple high-speed wires 21 are respectively embedded in multiple wire slots 103 of the wire clamp 13 and then inserted forward into multiple wire holes 102. Next, the front ends of the multiple high-speed wires 21 are processed. Then, the exposed wire cores of the processed high-speed wires 21 are soldered to the first PCB 12 to complete the assembly of the high-frequency PCBA assembly. Next, multiple power wires 22 and multiple low-speed wires 23 are passed through the fixing plug 16. Then, the front ends of the multiple power wires 22 and multiple low-speed wires 23 are soldered and fixed to the second PCB 15 and connected to form a conductive connection to complete the assembly of the power PCBA assembly. The high-frequency PCBA assembly is assembled and fixed in the first mounting cavity 101 from back to front, and the power PCBA assembly is assembled and fixed in the second mounting cavity 108 from back to front, thus obtaining a semi-finished product. Finally, the semi-finished product is subjected to low-pressure inner film molding to injection mold an inner film body 14 into the rear end openings of the first mounting cavity 101 and the second mounting cavity 108. The inner film body 14 seals and fixes the connector 10, effectively reinforcing the connection between the cable 20 and the connector 10. Finally, the above assembly actions are repeated to complete the assembly of the other end of the cable 20 with another connector 10, thus completing the assembly of the entire high-speed cable product.

[0043] The key design feature of this invention is that by setting a wire clamp, the high-speed wire is clamped and located behind the first PCB. The wire clamp can block the adhesive of the molded inner film, effectively preventing the inner film from covering the exposed wire core and PCB solder joint surface after stripping. This ensures that the high-frequency electrical characteristics of the product are not affected by the inner film, thereby helping to ensure the stability and reliability of signal transmission.

[0044] 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.
