Description

Technical Field

[0001] The utility model relates to the technical field of adapter sockets, in particular to a wall-penetrating adapter socket for a multi-mode optical switch. Background Art

[0002] A multimode optical switch is a data exchange device designed to process optical signals in multimode optical fibers. In optical fiber communications, multimode optical fibers can carry multiple modes (i.e., different paths) of light waves to transmit information compared to single-mode optical fibers. This usually means that multimode optical fibers have a larger core diameter, allowing light to enter at multiple angles and propagate in multiple paths within the optical fiber, making them suitable for short-distance transmission scenarios. When using a multimode optical switch, you need to connect the optical cable or optical patch cord to the optical port of the optical switch to ensure smooth transmission of the optical signal.

[0003] As the name implies, the through-the-wall adapter socket is an adapter socket installed on the wall. When connecting the optical cable on the optical switch to the adapter socket, you need to first gently insert one end of the optical cable connection line into the adapter socket to ensure that it is fully and correctly inserted. Then align the plug at the other end of the optical cable with the corresponding optical port of the optical switch, and push it vertically and gently until it locks into place. During the connection process, if the position of the optical cable connection line changes, the connection between the connector on the optical cable and the optical cable line will easily conflict with the adapter housing, resulting in bending. Long-term bending will cause the line in the plug to deform or break, affecting the safe use of the optical switch. Utility Model Content

[0004] In view of the above problems, the utility model proposes a multi-mode optical switch wall adapter socket to solve the disadvantage that during the connection process of the existing car carpet, if the position of the optical cable connecting line changes, the connection between the connector on the optical cable and the optical cable line will easily conflict with the adapter housing, resulting in bending.

[0023] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0024] according to Figure 1 , 2 As shown in Figures 3, 4 and 5, a multi-mode optical switch wall adapter socket is proposed in this embodiment, including a base plate 1, a wiring terminal A7 is provided on the front side of the base plate 1, a wiring terminal B10 is provided on the back side of the base plate 1, and the wiring terminal A7 is electrically connected to the wiring terminal B10; that is, the side of the base plate 1 on which the wiring terminal A7 is installed is the front side of the base plate 1, and the side on which the wiring terminal B10 is installed is the back side of the base plate 1, the base plate 1 is fixed on the wall hole where the line is arranged, the line connector in the wall hole is connected to the wiring terminal B10, and the plug on the optical switch is connected to the inclined surface 8.

[0025] A cover plate 2 is provided on the front side of the seat plate 1, one end of the cover plate 2 is rotatably connected to one end of the seat plate 1 through a rotating pin 9, and a snap-fit ​​structure is provided on the other end of the cover plate 2, and the cover plate 2 is snap-fitted to the other end of the seat plate 1 through the snap-fit ​​structure; the cover plate 2 is rotatably connected to cover the outer side of the seat plate 1, which can protect the wiring terminal A7 in the seat plate 1 and prevent the wiring terminal A7 from getting damp, and the snap-fit ​​fixing method strengthens the sealing between the seat plate 1 and the cover plate 2 without affecting the opening of the cover plate 2.

[0026] Regarding the connection between the optical switch transfer line and the connection terminal A7: a circular opening 4 is provided on the front of the cover plate 2, a fixing frame 5 is provided on the side of the circular opening 4 away from the connection terminal A7, an accordion-style sheath 6 is provided between the fixing frame 5 and the circular opening 4, and the two ends of the accordion-style sheath 6 are respectively fixedly connected to the fixing frame 5 and the circular opening 4. The plug on the optical switch is inserted into the cover plate 2 through the fixing frame 5, the accordion-style sheath 6 and the circular opening 4 and connected to the connection terminal A7. After the connection of the line is completed, the fixing frame 5 is pulled to expand the accordion-style sheath 6. The expanded accordion-style sheath 6 can protect the weak part of the connection between the plug and the line, thereby improving the service life of the plug.

[0027] It should be noted that the side of the terminal A7 facing the annular opening 4 is provided with an inclined surface 8, and the inclined surface 8 is inclined downward in the front area of ​​the seat plate 1. The advantage of the inclined setting is that the plug on the optical switch can be inserted into the cover plate 2 from the front of the seat plate 1 by upward oblique insertion to connect with the terminal A7. The advantage of such a design is that water droplets and dust outside the cover plate 2 will not fall into the cover plate 2 through the gap between the annular opening 4 and the plug.

[0028] See also Figure 3 , Figure 4 and Figure 5 , the specific structure of the buckle structure is:

[0029] The buckle structure includes at least one plug plate 13, which is arranged at one end of the cover plate 2 away from the rotating pin 9, and the plug plate 13 is fixedly connected to the side of the cover plate 2 facing the seat plate 1. The plug plate 13 is movably matched with the positioning groove 12 opened on the front side of the seat plate 1, and a movable groove 16 is opened on the inner side of the positioning groove 12. A ball pin 15 is provided in the movable groove 16, and the ball pin 15 is slidably connected to the movable groove 16. The ball pin 15 is fixedly connected to a spring 17 provided in the movable groove 16, and the end of the ball pin 15 away from the movable groove 16 is movably matched with the card slots 14 opened on both sides of the plug plate 13.

[0030] Combination Figure 5 , the specific working mode of the buckle structure is:

[0031] After the cover plate 2 covers the front of the seat plate 1, the plug plate 13 on the cover plate 2 will be inserted into the positioning groove 12, and the ball pin 15 will pop out from the movable groove 16 under the push of the spring 17, and then be stuck in the slots 14 opened on both sides of the plug plate 13, thereby preventing the plug plate 13 from being separated from the positioning groove 12. Since the ball pin 15 is spherical, when the cover plate 2 is opened, there will be no jamming between the ball pin 15 and the slot 14.

[0032] A better embodiment is that a baffle 3 is provided at one end of the cover plate 2 away from the rotating pin 9, and the baffle 3 is fixedly connected to the front side of the cover plate 2. When the user opens the cover plate 2, he pinches the baffle 3 and flips the cover plate 2 upwards.

[0033] Another better embodiment is that the lower end surface of the seat plate 1 is provided with a reinforcing rib 11, the reinforcing rib 11 is fixed to the inner side wall of the seat plate 1, and the reinforcing rib 11 includes a plurality of longitudinally arranged ribs and a plurality of transversely arranged ribs, each of which is staggered and fixedly connected to each other. The reinforcing rib 11 arranged inside the seat plate 1 can play the role of reinforcing ribs, and each of the ribs can support the seat plate 1 from the inside of the seat plate 1, thereby improving the structural strength and impact resistance of the seat plate 1.

[0034] In order to facilitate the user and to more clearly observe the connection status between the terminal A7 on the seat plate 1 and the plug, the cover plate 2 is made of transparent plastic. The transparent plastic can be of various types, such as but not limited to polymethyl methacrylate (PMMA), commonly known as acrylic or organic glass, polycarbonate (PC), polyethylene terephthalate (PET), polypropylene (PP), polyvinyl chloride (PVC), thermoplastic polyurethane elastomer rubber (TPU), polystyrene (PS), polysulfone (PSF), etc.

[0035] The working principle of the present application is as follows: the base plate 1 is fixed on the wall hole where the line is arranged, the line connector in the wall hole is connected to the terminal B10, and the plug on the optical switch is connected to the inclined surface 8. The cover plate 2 is covered on the outside of the base plate 1 by a rotating connection method, which can protect the terminal A7 in the base plate 1 and prevent the terminal A7 from getting wet. The snap-on fixing method strengthens the sealing between the base plate 1 and the cover plate 2 without affecting the opening of the cover plate 2. The plug on the optical switch is inserted into the cover plate 2 through the fixed frame 5, the accordion-type sheath 6 and the annular opening 4 and connected to the terminal A7. After the line connection is completed, the fixed frame 5 is pulled to expand the accordion-type sheath 6. The expanded accordion-type sheath 6 can protect the weak parts of the connection between the plug and the line, thereby increasing the service life of the plug.
