Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-6This utility model provides a composite structure grid-shaped LC adapter technical solution: it includes an adapter housing 1, one side of which is provided with a first plug hole 2, and four sets of the first plug holes 2 are provided, forming a grid-shaped structure. A first connecting terminal 3 is inserted into each of the four sets of the first plug holes 2. The other side of the adapter housing 1 is provided with a second plug hole 4, and four sets of the second plug holes 4 are provided, forming a grid-shaped structure. A second connecting terminal 5 is inserted into each of the four sets of the second plug holes 4. The first connecting terminal 3 and the second connecting terminal 5 are connected one-to-one through the adapter housing 1.

[0020] The adapter housing 1 has locking holes 7 on both sides of its outer wall, and first connecting blocks are provided on both sides of the first connecting terminal 3. When the first connecting terminal 3 is inserted into the first insertion hole 2, the first connecting block engages with the locking hole 7, making it easier and faster to install and remove the first connecting terminal 3, and ensuring a stable connection between the first connecting terminal 3 and the adapter housing 1.

[0021] The adapter housing 1 has integrally formed elastic latches 9 on both sides of its outer wall, and second connecting blocks on both sides of the second connecting terminal 5. The elastic latches 9 are used to fix the adapter housing 1 to the external device. The outer wall of the adapter housing 1 has a clearance groove 8 for avoiding movement of the elastic latches 9. The area of ​​the clearance groove 8 is larger than the area of ​​the elastic latches 9, and the area where the clearance groove 8 and the elastic latches 9 are misaligned is used to engage with the second connecting blocks. When the elastic latches 9 are integrally formed on the side of the adapter housing 1, a slot structure for engaging the second connecting terminal 5 is formed, thus integrating the internal and external connection structures of the adapter housing. This allows the adapter to be firmly connected to the external device through the elastic latches 9, ensuring stable signal transmission, and to engage with the second connecting terminal 5 through the misaligned area between the clearance groove 8 and the elastic latches 9. The structure is compact, small in size, and low in cost.

[0022] Combination Figure 2 As shown, the adapter housing 1 has protrusions 6 on both sides. The protrusions 6 not only enhance the structural strength of the adapter housing 1, but also provide users with space for easy gripping and operation.

[0023] Combination Figure 1 As shown, the locking hole 7 and the elastic locking block 9 are located on both sides of the boss 6, and two elastic locking blocks 9 are provided on each side of the outer wall of the adapter housing 1. The two elastic locking blocks 9 are located in their respective independent clearance slots 8. The fact that the adjacent clearance slots 8 are not connected makes the overall strength of the adapter housing 1 better.

[0024] Combination Figure 2As shown, an outer card unit 10 is provided on the outer side of the elastic card block 9, and the outer card unit 10 and the elastic card block 9 are integrally formed. The outer card unit 10 enables the adapter to be securely connected to the external device, ensuring stable signal transmission.

[0025] The inner side of the elastic locking block 9 is provided with an elastic rubber block 11. When the outer locking unit 10 is installed and connected to an external device, the elastic rubber block 11 contacts the second connecting terminal 5. The contact and compression between the elastic rubber block 11 and the second connecting terminal 5 further enhances the fixing effect of the second connecting terminal 5 within the adapter, preventing it from loosening due to vibration or external force during operation. This ensures the continuity and integrity of data transmission, not only improving the stability of the adapter but also greatly extending its service life.

[0026] The elastic rubber block 11 is an optional configuration. Figure 1 Elastic rubber block 11 was not installed in the middle. Figure 2 The structure of the elastic rubber block 11 is shown in the figure.

[0027] Optionally, an annular extended connecting groove can be provided on the periphery of the elastic block 9. The elastic block 11 has an annular structure. The elastic block 11 is sleeved on the periphery of the elastic block 9 and located in the connecting groove. The thickness of the inner side of the elastic block 11 near the adapter housing 1 is greater than the thickness of the outer side, that is, the thicker side of the elastic block 11 contacts the second connecting terminal 5.

[0028] Combination Figure 3 As shown, both the first connecting terminal 3 and the second connecting terminal 5 include a handle 12 and a core post 13 fixed to one side of the handle 12. Two sets of core posts 13 are provided, each with a limiting structure. The handle 12 facilitates gripping by the user during installation or removal of the connecting terminals, improving operational convenience. The limiting structure on the core post 13 effectively prevents excessive movement or misalignment of the connecting terminals within the adapter, further ensuring the accuracy and reliability of data transmission. This design makes the first connecting terminal 3 and the second connecting terminal 5 more stable during use, less prone to failure, and provides users with a more stable and efficient data transmission experience.

[0029] Combination Figure 3 As shown, the limiting structure includes a limiting block 14, which is fixedly installed on one side of the core post 13. Sliding protrusions 15 are fixedly installed on both sides of the limiting block 14. The limiting block 14 restricts the movement range of the connecting terminal within the adapter, preventing misalignment or detachment during use. The sliding protrusions 15 ensure a tighter fit between the limiting block 14 and the adapter's interior, further enhancing the fixing effect of the connecting terminal. The sliding characteristics of the sliding protrusions 15 also make the installation or removal of the connecting terminal smoother, reducing operational difficulty and improving work efficiency.

[0030] Combination Figure 6 As shown, a limiting groove 16 is provided on one side of both the first insertion hole 2 and the second insertion hole 4. The limiting groove 16 cooperates with the limiting block 14. Slide rails 17 are provided on both sides of the limiting groove 16, and the sliding protrusion 15 is movably mounted on the slide rail 17. The cooperation between the limiting groove 16 and the limiting block 14 not only further restricts the movement range of the connection terminal, but also ensures the precise positioning of the connection terminal within the adapter. This precise cooperation is crucial for the stability and accuracy of data transmission. At the same time, the slide rail 17 provides a stable movement path for the sliding protrusion 15, allowing the connection terminal to move smoothly along the preset path during installation or disassembly, avoiding damage or malfunction caused by improper operation.

[0031] Combination Figure 4 As shown, a dust cap 18 is provided on one side of the handle 12. The dust cap 18 can protect the mechanical structure or electronic components that may be exposed inside the adapter housing 1 from dust, dirt and other potential contaminants.

[0032] Working Principle: In use, the user first inserts the first connecting terminal 3 and the second connecting terminal 5 into the first insertion hole 2 and the second insertion hole 4, respectively. At this time, the limiting block 14 slides along the slide rail 17 and engages in the limiting groove 16, ensuring precise positioning of the connecting terminal within the adapter. Simultaneously, the first connecting block of the first connecting terminal 3 engages in the locking hole 7, and the second connecting block of the second connecting terminal 5 engages with the clearance groove 8, thus achieving a secure connection between the connecting terminal and the adapter. When connecting to external devices, the user can securely connect the adapter to the external device through the external locking unit 10, ensuring stable signal transmission. When not in use, the dust cap 18 effectively protects the inside of the adapter housing 1 from dust, dirt, and other contaminants, extending the adapter's lifespan.
