Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a high-speed cable connector. Background Technology

[0002] High-speed cables are one of the core components of communication systems, used to connect different communication devices for high-speed communication. These connectors support various protocols, commonly including OSFP, SFP, QSFP, XFP, and CFP. Taking the OSFP protocol optical module connector as an example, OSFP stands for Octal Small Form-factor Pluggable, a pluggable packaging form developed by the OSFP MSA organization. High-speed cable connectors have multiple high-speed electrical channels, supporting gigabit-level transmission. For example, 800G OSFP supports a transmission rate of 800Gbps. An 800G OSFP can be divided into eight high-speed electrical channels for data transmission, with each channel reaching a rate of 100Gbps. Existing high-speed cables typically consist of a metal sheath, a circuit board inside the sheath, and cables connected to the circuit board. The cables pass through the sheath into the interior. When connecting communication equipment, the cables are usually bent to ensure orderly wiring. However, the internal space of the metal sheath is limited, and the cable's insulation layer has a certain thickness. Usually, the internal wire bundle enters the sheath. Over time, the outer layer at the connection between the wire bundle and the metal sheath is prone to breakage, which may damage the internal wire bundle and affect its use. Therefore, a heat shrink tubing is fitted onto the cable during the production process. The heat shrink tubing contacts the metal sheath to protect the cable. However, the heat shrink tubing itself is a soft material and is still a vulnerable part. Furthermore, the production and assembly process requires an additional heating and cooling process, which relies on manual labor, is cumbersome, and consumes a lot of time, resulting in low production efficiency.

[0022] Bottom shell 1, cable inlet 11, first recessed part 12, second recessed part 13, groove 14, spring 15, flange 16, guide groove 17, rivet seat 18, connecting platform 19, top cover 2, rivet hole 21, heat dissipation part 22, limiting part 23, PCB 3, cable 4, buckle 5, first elastic snap-fit ​​arm 51, second elastic snap-fit ​​arm 52, handle 53, connecting part 54, guide part 55, protective part 6, connecting groove 61, inner sleeve 62, outer sleeve 63. Detailed Implementation

[0023] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0024] Reference Figures 1 to 5 This embodiment provides a high-speed cable connector, including a bottom shell 1, a top cover 2, a PCB 3, a cable 4, and a locking buckle 5. The PCB 3 is disposed inside the bottom shell 1, and the locking buckle 5 is connected to the bottom shell 1. The cable 4 is fitted with a protective component 6, which is connected to one end of the bottom shell 1. The end of the bottom shell 1 away from the cable inlet 11 is the insertion end, and the PCB 3 is located on the side of the bottom shell 1 near the insertion end.

[0025] The outer wall of the protective component 6 is provided with a connecting groove 61, which divides the protective component 6 into an inner sleeve 62 and an outer sleeve 63. The inner sleeve 62 is entirely located inside the bottom shell 1, while the outer sleeve 63 is located outside the bottom shell 1. The width of the inner sleeve 62 is greater than the width of the outer sleeve 63. The end of the bottom shell 1 is provided with a cable inlet 11 that matches the protective component 6. The connecting groove 61 of the protective component 6 is connected to the cable inlet 11, meaning the inner wall of the cable inlet 11 contacts the bottom of the connecting groove 61. Because the inner sleeve 62 is wider, the protective component 6 can be contained by the cable inlet 11, preventing it from falling off. The protective component 6 can be made of plastic and can be directly inserted into the cable 4 near its end during assembly. It can then be quickly snapped into the cable inlet 11, eliminating the heating and cooling processes required when using heat shrink tubing and significantly reducing assembly time.

[0026] like Figure 4 As shown, the latch 5 includes a first elastic snap-fit ​​arm 51, a second elastic snap-fit ​​arm 52, and a handle 53 connected to the first elastic snap-fit ​​arm 51 and the second elastic snap-fit ​​arm 52. The distance between the first elastic snap-fit ​​arm 51 and the second elastic snap-fit ​​arm 52 matches the width of the bottom shell. The opposite side walls of the bottom shell 1 are respectively provided with a first recess 12 and a second recess 13. The first elastic snap-fit ​​arm 51 and the second elastic snap-fit ​​arm 52 are respectively inserted into the side walls of the bottom shell from one end of the cable inlet 11, and the first elastic snap-fit ​​arm 51 and the second elastic snap-fit ​​arm 52 are respectively engaged in the first recess 12 and the second recess 13. Furthermore, the ends of the first elastic snap-fit ​​arm 51 and the second elastic snap-fit ​​arm 52 are each provided with a snap-fit ​​portion, which can be engaged into the corresponding position of the communication device socket to ensure a tight connection between the connector and the communication device.

[0027] like Figure 2 As shown, both the first recess 12 and the second recess 13 of the bottom shell 1 are provided with grooves 14, and springs 15 are provided in the two grooves 14. The spring 15 in the groove 14 of the first recess 12 is connected to the first elastic locking arm 51, and the spring 15 in the groove 14 of the second recess 13 is connected to the second elastic locking arm 52. The two springs 15 can respectively provide elastic force to the first elastic locking arm 51 and the second elastic locking arm 52, so that after the latch 5 is pulled, the latch 5 can return to its initial position under the elastic force of the springs 15.

[0028] Both the first elastic snap-fit ​​arm 51 and the second elastic snap-fit ​​arm 52 are provided with a connecting part 54 for connecting the spring 15. Taking the first elastic snap-fit ​​arm 51 as an example, one end of the spring 15 is connected to the connecting part 54, and the other end is connected to the inner wall of the groove 14. The same applies to the second elastic snap-fit ​​arm.

[0029] The bottom of the first recessed portion 12 and the second recessed portion 13 are both provided with a flange 16. A guide groove 17 is provided in the flange 16. The first elastic snap-fit ​​arm and the second elastic snap-fit ​​arm are both provided with guide portions 55 that match the guide groove 17. The corresponding position of the upper cover 2 can also be provided with the same guide groove 17. The upper end face of the corresponding first elastic snap-fit ​​arm and the second elastic snap-fit ​​arm also needs to be provided with guide portions 55. The guide portions protrude from a protrusion on the bottom surface of the first elastic snap-fit ​​arm / second elastic snap-fit ​​arm and are inserted into the guide groove 17. The cooperation of the guide groove 17 and the guide portion 55 makes the movement of the latch 5 more stable when pulled, and also plays a role in limiting the stroke to prevent displacement or disengagement. In addition, the flange 16 can cooperate with the upper cover 2 to limit the first elastic snap-fit ​​arm 51 and the second elastic snap-fit ​​arm 52 in the height direction.

[0030] Riveting seats 18 are provided on both inner walls of the bottom shell 1 near the inlet 11. The rivet seats 18 and the inlet 11 form a space to accommodate the inner sleeve 62. The upper cover 2 has rivet holes 21 corresponding to the rivet seats 18. The cooperation between the rivet seats 18 and the rivet holes 21 allows rivets to be installed vertically, thus providing ample space for the installation of the protective component 6. During assembly, rivets are used to pass through the rivet holes 21 and connect to the rivet seats 18 of the bottom shell 1 to lock the upper cover 2 and the bottom shell 1 together.

[0031] The bottom shell 1 is provided with several connecting platforms 19, and the PCB 3 is connected to the connecting platforms 19. The bottom surface of the top cover 2 is provided with several limiting parts 23 for limiting the PCB 3. The limiting parts are located on both sides of the bottom surface of the top cover, and the limiting parts are trapezoidal protrusions that contact the upper end surface of the PCB. The limiting parts 23 and the connecting platforms 19 cooperate to limit the position of the PCB 3, ensuring that the position of the PCB 3 will not shift. In addition, the side wall of the bottom shell 1 can also be provided with positioning blocks, and the PCB 3 is provided with positioning notches corresponding to the positions of the positioning blocks to facilitate the rapid positioning of the PCB 3 and achieve rapid assembly.

[0032] The top of the upper cover 2 is uniformly provided with a plurality of heat dissipation sections 22. In this embodiment, the heat dissipation sections 22 are plate-shaped and distributed in a rectangular array on the top surface of the upper cover 2. The heat dissipation sections 22 can quickly transfer heat outward during the use of the connector, avoiding overheating of the PCB3 and ensuring the performance of the connector.

[0033] This utility model provides a protective component 6 on the cable 4, which effectively protects the connection 54 between the cable 4 and the bottom shell 1. The protective component 6 has a connecting groove 61, which can be quickly inserted into the cable inlet 11 of the bottom shell 1 during assembly, eliminating the heating and cooling process required by using heat shrink tubing, simplifying the assembly operation, greatly shortening the connector assembly time, and improving production efficiency.
