[0007] A plurality of baffles are arranged on the latch.

[0008] A circular baffle is arranged on the large head of the latch.

[0009] When the optical cable is clamped, the clamped section is lapped on the large head of the latch through the hollow inner cavity, and the cooperation of the baffles and the circular baffle can prevent the cable from deviating laterally and separating from the latch during the installation of the optical cable, thereby ensuring the stability of the clamping of the optical cable and avoiding the separation of the optical cable from the lapping surface of the large head when the optical cable shakes.

[0035] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0036] like Figure 1 As shown, the optical cable clamping structure includes: a clamp housing 1, with a hollow inner cavity 2 extending through it. The cross-section of the hollow inner cavity 2 is an inverted trapezoid. The cable enters from the lower opening of the hollow inner cavity 2, passes around the upper opening of the hollow inner cavity 2, and then exits from the lower opening again, forming an arc above the upper opening of the hollow inner cavity 2; a pin 3, with the same cross-section as the hollow inner cavity 2, is inserted into the hollow inner cavity 2. The pin 3 includes a large round head 301 and a small round head 302. When the pin 3 is inserted into the hollow inner cavity 2, the large round head 301 and the small round head 302 are located at the two openings on both sides of the hollow inner cavity 2. The arc formed by the optical cable after passing around the hollow inner cavity 2 overlaps the outer surface of the large round head 301; by pressing the entire pin 3, the optical cable is clamped between the inner wall of the hollow inner cavity 2 and the outer surface of the pin 3.

[0037] It also includes several baffles 4, which are set on the pin 3 to prevent the optical cable from moving too far laterally during clamping and coming off the pin 3.

[0038] A circular baffle 5 extends outward from the large round head 301 and is used in conjunction with the baffle 4 to make the optical cable forming the arc section fit together with the outer surface of the large round head 301.

[0039] The optical cable can be quickly clamped by the pin 3 in conjunction with the clamp housing 1 with the hollow inner cavity 2, which can prevent the optical cable from shifting laterally during installation due to operation or wind direction.

[0040] Furthermore, the two sides of the pin 3 are equidistantly arranged with several grooves 6. The grooves 6 are formed by multiple identical locking blocks 11 fixed at equal intervals on the side of the pin 3. The larger the spacing between the locking blocks 11, the wider the groove 6 is, and vice versa.

[0041] In one embodiment, such as Figures 4-6As shown, the cross section of the card block 11 can be triangular, rectangular, trapezoidal, half polygon, by changing the cross section shape of the card block 11, the cross section shape of the groove formed by the card block 11 can be adjusted, so that when the optical cable is attached to the side wall of the plug 3 with the concave-convex groove 6, the curvature of the optical cable when clamped is different, and the axial friction force received is also different, so that different shape concave-convex groove 6 of the plug 3 can be selected according to the actual working condition to clamp and fix the optical cable. In the cross section of the card block 11, the more the corners, the more the contact points between the optical cable, the smoother the clamping line formed when the optical cable is clamped and pressed, the smaller the friction force received by the cable, and the more difficult the core inside the cable to break, otherwise, the bending angle of the clamping line formed when the cable is pressed is larger, the friction force is larger, and the clamping force of the plug 3 on the cable is larger.

[0042] In an embodiment, as shown in Figure 1 A flexible connecting line 7 is provided between the wire clamp shell 1 and the plug 3, so that the operator does not need to pick up parts many times, and the installation of the optical cable is facilitated.

[0043] In an embodiment, as shown in Figure 2 And Figure 3 The position of the baffle 4 on the plug 3 can be adjusted by the sliding baffle 4.

[0044] Specifically, the side edges of the upper and lower surfaces of the plug 3 are provided with a clamping sliding groove 10, the baffle 4 includes a sliding block 401, the sliding block 401 is slidably connected with an extension block 403, the extension block 403 is provided with a clamping block 402, the clamping block 402 is elastic, during installation, the clamping block 402 is clamped into the clamping sliding groove 10, so that the baffle 4 is installed on the plug 3, the elastic clamping block 402 can abut against the inner side of the clamping sliding groove 10, so that the baffle 4 stably slides in the clamping sliding groove 10, by adjusting the clamping position of the baffle 4 in the clamping sliding groove 10, the density of the baffle 4 can be adjusted in real time, so that different numbers of baffles 4 can be installed according to the actual situation. At the same time, the baffle 4 is detachably provided on the plug 3, which can facilitate subsequent maintenance.

[0045] Further, as shown in Figure 3 A spring 12 is arranged inside the sliding block 401 slidingly connected with the extension block 403, the clamping sliding groove 10 is provided with a clamping port, the upper and lower surfaces of the sliding block 401 are inclined, which can cooperate with the spring 12 to clamp and fix the entire baffle 4 in the clamping sliding groove 10, during the clamping process, by drawing the clamping block 402 into the opening of the clamping sliding groove 10, the extension block 403 can be pushed out by the spring 12, so that the inclined surface of the sliding block 401 abuts against the clamping sliding groove 10, thereby cooperating with the clamping block 402 to install the entire baffle on the plug 3.

[0046] Further, the circular baffle 5 is integrally injection molded with the latch 3, and the connection between the two ends of the circular baffle 5 and the two side surfaces of the latch 3 is a smooth transition surface. The smooth transition design reduces stress concentration, improves the strength and durability of the overall structure, avoids sharp edges, and reduces the risk of damage that may occur during use. The fit between the optical cable and the latch 3 is more closely, and the gap between the optical cable and the latch 3 can be reduced.

[0047] Further, as shown in Figure 1 The wire clamp shell 1 is hook-shaped, including a first shell 101 and a second shell 102 integrally formed, and the hollow cavity 2 is arranged in the first shell 101.

[0048] The second shell 102 extends upward from one side of the first shell 101, and the side surface close to the hollow cavity 2 is open. After the optical cable is clamped, it can extend upward along the inner side of the second shell 102, thereby preventing the optical cable from frequently shaking during clamping. The upwardly extending second shell 102 provides an additional mounting point or fixing surface, so that the wire clamp can be more easily connected with the mounting bracket, wire or other equipment.

[0049] A hanging hole 8 for hanging the entire clamping structure is provided through the second shell 102, and the extended end of the second shell 102 is a smooth arc surface 9. The smooth arc surface 9 makes the extended end of the second shell 102 more rounded, reducing the discomfort or scratching risk that may be caused by sharp edges. This provides a better hand feel and comfort when the user touches or operates.
