[0002] Connectors, also known as plugs or sockets, generally refer to electrical connectors. They are devices that connect two active devices to transmit current or signals. They can be classified into many different types according to their application, installation method, special structure, and special performance, and often appear in publications and manufacturers' promotional materials. Connecting kits are also a type of connector, mainly including board-end assemblies and wire-end assemblies.

[0003] Existing connector kits use a threaded locking connection to be fixed to external parts during plug-in installation. This requires sufficient space for tightening the threads, resulting in a large space requirement that cannot meet the needs of miniaturized, high-density products. Furthermore, unlocking the connector kit is cumbersome and cannot meet users' needs for quick plug-and-play functionality. Therefore, it is necessary to further improve the structure of the existing connector kit. Utility Model Content

[0042] Please refer to Figures 1 to 5 As shown, it illustrates the specific structure of the first preferred embodiment of the present invention, including a board-end assembly 10 installed with an external device and a line-end assembly 20 connected in conjunction with the board-end assembly 10.

[0043] The plate-end assembly 10 includes a housing 11. At the end of the housing 11 furthest from the external device, there is an insertion cavity 101 for inserting a connector. The inner wall of the opening of the insertion cavity 101 has a first retaining groove 102. In this embodiment, the plate-end assembly 10 also includes a sealing ring 12. The side of the housing 11 closest to the external device has a recessed first sealing groove 103. The sealing ring 12 is embedded in the first sealing groove 103 and makes pressure contact with the external device, thereby increasing the sealing between the plate-end assembly 10 and the external device after installation, preventing moisture from entering the interior through gaps between the plate-end assembly 10 and the external device housing. The side of the housing 11 closest to the external device has a recessed fixing hole 104. The housing 10 is fixedly installed on the external device by external fixing screws 13 passing through the external device and the fixing hole 104 in sequence. Two first retaining grooves 102 are symmetrically arranged.

[0044] The wire end assembly 20 includes a main shell 21, a sealing sleeve 22, a sealing cylinder 23, and a fixing member 24. The main shell 21 is made of rigid material. The front end of the main shell 21 is inserted into the plate end assembly 10. An elastic part 211 is integrally formed on the front end of the main shell 21. A pressing part 212 and a buckle 213 that cooperates with the first slot 102 are integrally formed on the elastic part 211. The buckle 213 is located at the end of the elastic part 211 near the plate end assembly 10. When unlocking, the pressing part 212 is pressed down, which causes the elastic part 211 and the buckle 213 to move downward and disengage from the corresponding first slot 102, thereby realizing the unlocking process between the wire end assembly 20 and the plate end assembly 10. The main shell 21 has an installation cavity 201 that penetrates the front and rear end faces of the main shell 21. In this embodiment, there are two installation cavities 201, which are separated by a partition 214. The outer wall of the main shell 21 and the plate end assembly 10 insertion portion is recessed inward with an annular groove 203. The outer wall of the pressing part 212 is recessed inward with an adapter groove 204. A fixing block 25 is provided in the mounting cavity 201, and a through groove 205 for external wire harnesses to pass through is provided in the fixing block 25. The fixing block 25 limits and fixes the wire harnesses in the mounting cavity 201. Each elastic part 211 is integrally formed with a pressing part 212 and a buckle 213 that cooperates with the first card slot 102. The cooperation of the two first card slots 102 and the two buckles 213 makes the unlocking process faster and more suitable for the unlocking process of dual-port connection kits.

[0045] The sealing sleeve 22 is made of soft rubber and is embedded and fixed together with the main body shell 21. The front end of the sealing sleeve 22 is attached to the outer surface of the pressing part 212, so that it can be pressed on the sealing sleeve 22 when pressed. This not only improves the pressing feel, but also makes the sealing sleeve 22 more slip-resistant, preventing slippage during pressing and ensuring the stability of the unlocking process. The rear end of the sealing sleeve 22 has a fitting part 221. In this embodiment, the front end of the sealing sleeve 22 extends integrally into the groove 203 and forms an annular sealing part 222. The sealing part 222 is embedded in the groove 203 and makes pressure contact with the inner sidewall of the insertion cavity 101. The sealing part 222 can increase the sealing performance of the insertion part between the main body shell 21 and the plate end assembly 10, and further improve the overall waterproof performance. The portion of the sealing sleeve 22 that is attached to the pressing part 212 is integrally formed inward to form an adapter part 223 that mates with the adapter groove 204. The portion of the sealing sleeve 22 that is attached to the pressing part 212 is fixedly installed together with the pressing part 212 through the cooperation of the adapter part 223 and the adapter groove 204. Similarly, in other embodiments, it can also be fixedly installed together with the pressing part 212 by adhesive.

[0046] The sealing cylinder 23 has through holes 202 formed on its front and rear end faces for external wire harnesses to pass through. The sealing cylinder 23 is sealed and fixed by a fitting part 221. In this embodiment, there are two fitting parts 221, each corresponding to a mounting cavity 201. Each fitting part 221 contains a sealing cylinder 23, allowing the external wire harness to extend outward through modular arrangement, further facilitating the user's operation. The sealing cylinder 23 is used to seal the rear end of the wire harness and, through the cooperation of the fitting part 221, increases the waterproof performance of the rear end of the wire end assembly 20.

[0047] The fastener 24 is fitted and tightened around the outer periphery of the fitting part 221, thereby fixing the fitting part 221 and the sealing cylinder 23 together. In this embodiment, the fastener 24 includes a fixing part 241 and a rotating part 242. One end of the rotating part 242 is rotatably mounted on the fixing part 241, and the other end of the rotating part 242 is engaged with the fixing part 241, forming a fixing groove 206 that cooperates with the fitting part 221. Two rotating parts 242 are provided, and each rotating part 242 forms a corresponding fixing groove 206 with the fixing part 241. Similarly, multiple rotating parts 242 can be provided according to actual needs, thereby forming a corresponding number of fixing grooves 206 with the fixing part 241. The number of rotating parts 242 is not limited. A crossbar 243 is provided on the fixed part 241, and a second slot 207 that cooperates with the crossbar 243 is provided on the movable end of the rotating part 242. The movable end of the rotating part 242 and the fixed part 241 are fixed together by the cooperation of the second slot 207 and the crossbar 243.

[0048] The assembly process of this embodiment is described in detail below:

[0049] During assembly, the housing 11 is first installed together with the external device using fixing screws 13. Then, the corresponding optical module is inserted into the insertion cavity 101. This completes the installation process of the board-end assembly 10. Next, the external wire harness is inserted into the mounting cavity 201 from back to front and connected to the corresponding optical module. Then, the fixing block 25 is fixed on the wire harness, and the sealing cylinder 23 is fitted onto the wire harness. Then, the main housing 21 is moved toward the board-end assembly 10, and the corresponding buckles 213 are moved inward by pressing the two pressing parts 212. When the main housing 21 is in place, the pressing parts 212 are released, so that the two buckles 213 are engaged with the corresponding first slot 102. Finally, the fixing part 24 is installed on the outside of the fitting part.

[0050] Please refer to Figure 6 As shown, it illustrates the specific structure of the second preferred embodiment of the present invention, which is basically the same as the structure of the aforementioned first preferred embodiment, except that:

[0051] In this embodiment, the mounting cavity 201 is a single unit, and correspondingly, the fitting part 221 and the sealing cylinder 23 are also single units; this structure is a single-port connection kit structure; the first slot 102 is located on the inner wall of one side of the insertion cavity 101, and correspondingly, the elastic part 22 is also a single unit, located on the same side as the first slot 102. Because the single-port connection kit has a small overall size, the unlocking process can be achieved through the single first slot 102 and the elastic part 22.

[0052] The key design features of this invention are: a first slot is provided on the inner wall of the insertion cavity opening, with two symmetrically arranged slots; an elastic part is integrally formed on the front end of the main body shell, and a pressing part and a buckle that mates with the first slot are integrally formed on the elastic part. When unlocking, pressing the elastic part causes the buckle on the elastic part to disengage from the corresponding first slot, thus completing a quick unlocking process. This eliminates the need for the large installation space required for threaded connections, thereby meeting the requirements of miniaturized, high-density products. Simultaneously, the sealing sleeve is made of soft rubber, with its front end fitting against the outer surface of the pressing part; this improves the feel and anti-slip effect when pressing, eliminating the need for an anti-slip surface on the pressing part and reducing processing costs to some extent.

[0053] 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.
