Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a novel high-speed optical connector. Background Technology

[0002] High-speed connectors are key components in modern electronic devices for enabling high-frequency, high-speed signal transmission, and are widely used in servers, switches, data centers, and other fields. With the continuous increase in data transmission rates, increasingly higher requirements are being placed on the signal integrity (SI), structural stability, and reliability of connectors.

[0003] Existing high-speed connectors typically suffer from the following structural design problems:

[0004] Insufficient terminal assembly stability: In traditional connectors, terminal assemblies are typically made using one-piece injection molding or simple linear arrangement. When subjected to external insertion / extraction forces or assembly stress, the entire terminal assembly is prone to tilting or shifting, resulting in poor terminal alignment (position accuracy), affecting contact reliability, and in severe cases, even causing signal transmission failure.

[0005] Assembly accuracy and reliability are difficult to guarantee: If there is a lack of a unified, high-precision positioning reference when multiple terminal components are installed into the connector body, cumulative errors in the relative positions of the components will occur. The assembly process is complex, and there is a risk of loosening of the components after assembly. Reliability decreases after long-term use under conditions such as vibration.

[0006] Therefore, how to design a high-speed connector with stable structure, high assembly precision, and reliable use is a technical problem that urgently needs to be solved in this field. Utility Model Content

[0011] Preferably, the second B guide post has a buckle on its locking block, and the main body has a locking hole at the position of the first locking groove that cooperates with the buckle, and the buckle is locked in the locking hole.

[0012] Preferably, the A-group terminal assembly further includes a plurality of A terminals; a first retaining groove is provided on both the first A guide post and the second A guide post along its length direction; one end of the A terminal is engaged with the first retaining groove of the first A guide post, and the other end is engaged with the first retaining groove of the second A guide post; the first A guide post and the second A guide post are spatially staggered.

[0013] Preferably, the middle section of terminal A is bent.

[0014] Preferably, the B-group terminal assembly further includes a plurality of B terminals; a second retaining groove is provided on both the first B guide post and the second B guide post along its length direction; one end of the B terminal is engaged with the second retaining groove of the first B guide post, and the other end is engaged with the second retaining groove of the second B guide post; the first B guide post and the second B guide post are spatially staggered.

[0019] Beneficial effects

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The structure is extremely stable and reliable: by designing the guide posts of the terminal assembly to be arranged in a spatially staggered manner, the two ends of the terminal are fixed in different spatial positions, which greatly enhances the anti-tilting and anti-torsion capabilities of the terminal assembly itself; at the same time, the same first slot on the main body is used as the common positioning reference for the A and B sets of terminal assemblies, and the two are mutually resisted to form a stable self-locking structure, which ensures the stability and high precision of the entire internal components of the connector.

The final snap-locking structure ensures that the assembly is completed in one step and is secure and reliable, preventing loosening.

[0023] Extending product lifespan: By designing the surface of the terminal that contacts the external gold finger as the collapsed corner side during stamping, the burr side is avoided from scratching the gold plating layer of the gold finger, significantly improving the number of mating and unmating cycles and the service life of the connector.

[0024] Excellent signal transmission performance: The notches on both sides of the terminals form a functional structure that meets SI performance after being arranged, effectively controlling impedance and reducing crosstalk; the common ground plate further ensures the stability of the signal return path, providing a guarantee for high-speed signal transmission.

[0025] Good overall integrity and beautiful appearance: The rear insertion assembly method reduces the splicing lines of the components on the surface of the finished connector, making the whole unit seamless and enhancing the commercial value of the product. Attached Figure Description

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art will be able to understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0038] Please see Figures 1 to 8 This utility model provides a novel high-speed optical connector, including a main body (1), an A-group terminal assembly (2) and a B-group terminal assembly (3).

[0039] The structure of the main body (1) is as follows Figure 1 and Figure 2 as well as Figure 8 As shown, the main body (1) is typically injection molded from insulating material, and has an internal mounting groove (11) for accommodating and installing terminal assemblies. To achieve precise and secure installation of the terminal assemblies, a specific slot structure is designed on the inner sidewall of the mounting groove (11). Specifically, a first slot (12) is provided on both sides of the lower rear half of the mounting groove (11); a second slot (13) is provided on both sides of the upper front half of the mounting groove (11); and a third slot (14) is provided on both sides of the lower front half of the mounting groove (11). The different spatial layouts of these three slots provide guidance and positioning for subsequent sequential assembly.

[0040] The internal structures of terminal assembly A (2) and terminal assembly B (3) are as follows: Figure 3 As shown, the A-group terminal assembly (2) is one of the core components of this solution. It includes several A-terminals (21), a first A-guide post (22), and a second A-guide post (23). Both the first A-guide post (22) and the second A-guide post (23) have first retaining grooves (24) along their length for snapping and fixing the A-terminals (21). The middle section of the A-terminal (21) is bent, and its two ends are respectively fixed in the first retaining grooves (24) of the first A-guide post (22) and the second A-guide post (23) by snapping. A key technical feature is that the first A-guide post (22) and the second A-guide post (23) are spatially staggered. This means that they are not simply arranged in parallel, but rather offset in space. This design allows the fixed A-terminals (21) to form a stable structure with spatial tension, greatly improving the overall rigidity of the A-group terminal assembly (2) and effectively preventing tilting during use or assembly. Similarly, the B-group terminal assembly (3) also has a similar structure, including several B terminals (31), a first B guide post (32), and a second B guide post (33). A second retaining groove (34) is provided on the guide post for fixing the B terminals (31), and the first B guide post (32) and the second B guide post (33) are also arranged in a spatially staggered manner to achieve the same stabilizing effect.

[0041] Assembly Relationships and Cooperative Positioning Structure: Another core aspect of this solution lies in its unique assembly method. (See figure) Figures 4 to 8As shown, all guide posts have locking blocks (4) at both ends. The assembly process is as follows:

[0042] First, push the A-group terminal assembly (2) into the rear end of the mounting slot (11) so that the locking block (4) of its first A guide post (22) is engaged in the second locking slot (13) at the front end.

[0043] Next, continue pushing in the A-group terminal assembly (2) so that the locking block (4) of its second A guide post (23) engages in the first locking slot (12) on the rear side.

[0044] Then, push the B-group terminal assembly (3) into the rear end of the mounting slot (11) so that the locking block (4) of its first B guide post (32) is engaged in the third locking slot (14) at the front end.

[0045] Finally, continue pushing in the B-group terminal assembly (3) so that the locking block (4) of its second B guide post (33) also engages in the same first slot (12) on the rear side.

[0046] At this time, the locking block (4) of the second A guide post (23) and the locking block (4) of the second B guide post (33) abut against each other in the first slot (12). This design makes the first slot (12) a common positioning reference for the two sets of terminal assemblies A and B. Through the interaction force between the two, an extremely stable self-locking state is achieved, ensuring the relative position accuracy of the two components and the stability of the overall structure.

[0047] Locking and assisted positioning structures such as Figure 1 , Figure 2 as well as Figure 6 As shown, to ensure the final reliability of the assembly, a resilient buckle (331) is provided protruding from the side end of the latch (4) of the second B guide post (33). A latching hole (15) is provided on the main body (1) at a position corresponding to the first latching groove (12). When the second B guide post (33) is fully pushed into place, the buckle (331) will automatically spring in due to elastic deformation and lock into the latching hole (15), emitting a crisp sound, indicating that the assembly is complete and securely locked, preventing the component from accidentally slipping out. Furthermore, as... Figure 1 as well as Figure 2 As shown, the mounting slot (11) has positioning slots (16) on both the upper and lower sides of its front end. When the A-group terminal assembly (2) and the B-group terminal assembly (3) are installed in place, the contacts of the A-terminal (21) will be inserted into the upper positioning slot (16), and the contacts of the B-terminal (31) will be inserted into the lower positioning slot (16). This provides secondary precise positioning for the functional contact parts of the terminals, ensuring the alignment accuracy between them and the gold fingers of the external circuit board.

[0048] Other functional structures such as Figure 4 as well as Figure 6As shown, to meet the requirements of high-speed signal transmission, notches (6) are provided on both sides of terminals A (21) and B (31). When multiple terminals are arranged side by side, these notches (6) together form a functional air gap structure, which helps to adjust impedance, reduce signal crosstalk, and thus improve signal integrity (SI) performance. At the same time, between terminals that need to share a common ground, such as between adjacent terminals A (21), a common ground plate (5) can be provided and firmly connected to the terminals by means of laser welding, etc., to provide a stable and reliable signal return path. In order to extend the product life, the contact surfaces of terminals A (21) and B (31) that contact the external gold fingers are specially designed as the corner side of the terminals during stamping. The corner side surface is smooth and there are no sharp burrs generated by stamping, which can effectively avoid scratching the gold plating layer of the gold fingers during insertion and removal, thereby greatly increasing the durability and insertion and removal cycles of the connector.

[0049] This invention, through its innovative "misaligned guide post" stabilizing structure and "shared reference slot" collaborative assembly structure, supplemented by designs for locking, positioning, signal optimization, and lifespan extension, successfully solves many problems in the prior art and provides a new type of high-speed optical connector with excellent performance.

[0050] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
