Problems solved by technology
[0003] When the above-mentioned signal transmission module is manufactured, the insulator is usually injection-molded on the outside of the signal contact at one time, and then the shielding ring is installed. The injection pressure is relatively high, it is easy to offset the signal contacts, and the correct position of the two signal contacts cannot be guaranteed, resulting in unqualified quality of the signal transmission module and a high scrap rate

Embodiment Construction
[0031] An example of a fully shielded high-speed signal transmission module in the present invention is figure 1 and figure 2 As shown, it includes two signal contacts 3 inside, an insulator 2 injection-molded on the outside of the signal contacts 3 , and two U-shaped shells 1 mounted on the outside of the insulator 2 .
[0032] Wherein, the two U-shaped shells 1 are fixedly connected together by dislocation butt joints to form a shielding shell surrounding the insulator 2 . Specifically, the two U-shaped shells 1 are formed by stamping metal strips, and the two U-shaped shells 1 have the same structure. Taking one of them as an example, as Figure 5 As shown, the U-shaped shell 1 is provided with a plurality of snap holes 12 and buckles 13 for buckle connection, and the snap holes 12 on one U-shaped shell are interlocked with the buckles 13 on the other U-shaped shell. In order to facilitate the fastening connection, while ensuring the flatness and beauty of the U-shaped s...

The invention relates to the technical field of connectors, in particular to a full-shielding high-speed signal transmission module, a manufacturing method thereof and an adapter connector. The manufacturing method for the full-shielding high-speed signal transmission module comprises the following steps: firstly, at least one set of signal contact pieces are stamped on a metal material belt, eachset comprises two signal contact pieces with a set interval, and the two signal contact pieces are connected with the metal material belt through a material connecting structure; secondly, a primaryinjection molding insulator is formed outside the two signal contact pieces through primary injection molding; thirdly, a secondary injection molding insulator is formed outside the primary injectionmolding insulator through secondary injection molding; fourthly, the material connecting structure is cut off, and an insert structure is obtained; and fifthly, a shielding shell is installed outsidethe insert structure. The beneficial effects are that the insulator is formed through two times of injection molding, the material connecting structure is cut off, and the shielding shell is installed, thereby guaranteeing the correct positions of the two signal contact pieces, improving the product quality, and reducing the rejection rate.
Description
technical field [0001] The invention relates to the technical field of connectors, in particular to a fully shielded high-speed signal transmission module, a manufacturing method thereof, and a transfer connector. Background technique [0002] The high-speed signal transfer connector is composed of a plurality of high-speed signal transmission modules. At present, the high-speed signal transmission module usually adopts a fully shielded type. Transmission module, the signal transmission module includes two signal conductors (that is, two signal contacts), an insulator arranged outside the signal contacts, and a shielding ring set outside the insulator, wherein the shielding ring consists of two U-shaped The shells are dislocated and buckled, and the signal contacts are fully shielded through the external insulator and the shielding ring. When it is specifically applied to a transfer connector, it can prevent mutual interference between multiple signal contacts. [0003] Whe...
