Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides an interface fixing mechanism as Figures 1-3 shown, which includes a locking plate 1, a protective pad 2, a hinge assembly 3 and a positioning assembly 4. The protective pad 2 is fixedly connected to the bottom of the locking plate 1. The hinge assembly 3 is arranged at one end of the locking plate 1. The hinge assembly 3 includes a connecting block 31 and a connecting shaft 32. A second slot matching the connecting block 31 is opened at one end of the locking plate 1. The end of the connecting shaft 32 is fixedly connected to the connecting block 31. The outer wall of the connecting shaft 32 is rotatably inserted and sleeved with the locking plate 1. The locking plate 1 can rotate relative to the connecting block 31 through the connecting shaft 32. The positioning assembly 4 is arranged at the other end of the locking plate 1. The positioning assembly 4 includes a fixing block 41, a fixing housing 42 and a positioning block 43. A first slot is opened at the other end of the locking plate 1. The fixing block 41 is located inside the first slot. The fixing housing 42 is clamped on the top of the fixing block 41. The positioning block 43 is fixedly connected to the bottom of the side of the fixing housing 42. The bottom of the positioning block 43 is in pressing fit with the locking plate 1. And both the connecting block 31 and the fixing block 41 are installed on the component connected to the flexible cable. Thus, when the fixing housing 42 and the positioning block 43 lock the locking plate 1, the protective pad 2 at the bottom of the locking plate 1 can cooperate with the component connected to the flexible cable to clamp and fix the flexible cable, ensuring the stability of the installation of the flexible cable.

[0028] Preferably, first connecting plates 44 are symmetrically and fixedly connected to the top of the fixing block 41. The outer wall of the first connecting plate 44 is slidably inserted and sleeved with the fixing shell 42. Second connecting plates 45 are symmetrically and slidably connected to the inside of the fixing shell 42. A locking block 46 is fixedly connected to the side of the second connecting plate 45 facing the first connecting plate 44. A locking hole is formed in the top of one side of the first connecting plate 44. The outer wall of the locking block 46 is slidably sleeved with the inner cavity of the locking hole. A limiting spring 412 is arranged on the side of the second connecting plate 45 away from the locking block 46. Under the action of the limiting spring 412, the second connecting plate 45 can drive the locking block 46 to maintain a stable clamping state with the first connecting plate 44, so as to ensure the stability of the fixing shell 42 clamped on the top of the fixing block 41.

[0029] Preferably, fixing plates 47 are symmetrically and fixedly connected to the top of the inner wall of the fixing shell 42. A guide rod 48 is fixedly connected between the fixing plate 47 and the inner wall of the fixing shell 42. The outer wall of the guide rod 48 is slidably inserted and sleeved with the second connecting plate 45. The guide rod 48 can ensure the stability of the horizontal sliding of the second connecting plate 45 inside the fixing shell 42. An extrusion rod 49 is arranged inside the fixing shell 42. A bottom plate 410 is fixedly connected to the bottom of the extrusion rod 49. A connecting rope 411 is fixedly connected between the bottom plate 410 and the second connecting plate 45. A wire arranging hole matching the connecting rope 411 is formed in one side of the fixing plate 47. The outer wall of the connecting rope 411 is slidably sleeved with the limiting spring 412. A limiting collar 413 is slidably sleeved on the outer wall of the extrusion rod 49. The side of the limiting collar 413 is fixedly connected to the fixing plate 47. A button 414 is fixedly connected to the top of the extrusion rod 49. A through hole is formed in the top of the fixing shell 42. The outer wall of the button 414 is slidably sleeved with the inner cavity of the through hole, and the top of the button 414 is on the same plane as the top of the fixing shell 42. Thus, by squeezing the button 414 into the inside of the fixing shell 42, the button 414 can drive the bottom plate 410 to descend through the extrusion rod 49. Thus, the bottom plate 410 drives the connecting rope 411, and the connecting rope 411 drives the second connecting plate 45 to move away from the first connecting plate 44, thereby unlocking the fixing shell 42. Removing the fixing shell 42 allows the locking plate 1 to be rotated and opened, so as to facilitate the installation or disassembly of the flexible cable.

[0030] As Figure 1 shown, this embodiment provides a flexible cable, and the flexible cable includes the above-mentioned interface fixing mechanism.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
