Description

Technical Field

[0001] This utility model relates to the field of fiber optic patch cord clamping technology, specifically to an auxiliary clamping device for fiber optic patch cord connections. Background Technology

[0002] Fiber optic patch cords (also called fiber optic patch cords) are a crucial component of fiber optic communication systems, typically used to connect short-distance links between fiber optic devices. The clamping device used in fiber optic patch cord connections is an essential tool for ensuring the stability of the patch cord during cabling or connection, preventing damage, and improving management efficiency. It not only prevents the patch cord from bending and stretching but also helps to neatly organize and manage the fiber optic cables, enhancing system maintainability and aesthetics.

[0003] For example, a fiber optic patch cord clamping device, disclosed in CN219599101U, relates to the technical field of clamping devices. Specifically, it is a fiber optic patch cord clamping device comprising a limiting block fixedly connected to the upper surface of a base plate. A fastening ring is threaded onto the surface of the limiting block, and a limiting sleeve is threaded onto the inner wall of the fastening ring. A support rod is bolted to the center of the upper surface of the base plate, and a cable reel is fixedly connected to the upper surface of the support rod. A limiting spring is fixedly connected to the surface of the cable reel. The protective spring prevents damage to the fiber optic cable due to excessive bending during use. The combination of the protective spring and the limiting spring allows the limiting spring to deflect according to the direction of force when the device is used, thereby reducing the force on the fiber optic cable and reducing fiber optic loss.

[0004] The aforementioned patent proposes that two limiting beads are distributed symmetrically along the central vertical line of the limiting sleeve. The limiting beads can hold the patch cord connector tightly in place, and the limiting hole can limit the clamping structure of the patch cord connector. However, in actual use, as the fiber optic patch cord bends, the patch cord connector will come off between the two sets of limiting beads, causing the fiber optic patch cord to fall out of the clamping device, which is inconvenient to use.

[0005] Therefore, we propose an auxiliary clamping device for fiber optic patch cord connections to solve the problems mentioned above. Utility Model Content

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.

[0023] Example 1: Please refer to Figures 1-4A fiber optic patch cord connection auxiliary clamping device includes a clamping structure 1. The clamping structure 1 includes a bottom circular plate 11 and a conduit 111 that is installed through the periphery of the bottom circular plate 11. A clamping member 12 is installed at the top of the conduit 111 and above the bottom circular plate 11. A central rod member 15 is installed through the middle of the bottom circular plate 11. A bottom rotating groove 119 is opened in the middle of the bottom end of the bottom circular plate 11. A threaded connection hole 113 is opened on the inner side of the bottom rotating groove 119. A threaded groove 112 is opened at the lower end of the conduit 111. A lower bundle member 16 is installed inside the conduit 111.

[0024] The middle rod component 15 includes a rotating tube 151 and a limiting plate 152 installed at the bottom end of the rotating tube 151. The limiting plate 152 is located inside the bottom rotating groove 119 and inside the threaded connection hole 113. A lower limiting ring 114 is installed at the lower end of the limiting plate 152. A connecting bolt 115 is threadedly connected to the outer surface of the lower limiting ring 114. The threaded end of the connecting bolt 115 is threaded into the inside of the threaded connection hole 113. A rotating ring 17 is installed on the outer surface of the rotating tube 151 and at the top of the bottom circular plate 11. A wire clamping plate 116 is installed on the outer surface of the rotating tube 151 and at the top of the rotating ring 17. A clamping groove 117 is opened on the outer side of the wire clamping plate 116. A shifting clamp component 13 is installed on the outer side of the rotating ring 17. A wire harness 18 is installed on the outer surface of the rotating tube 151 and above the wire clamping plate 116.

[0025] The clamping component 12 includes a bent clamping half tube A121 and a rubber semicircular pad A122 installed on the upper end of the inner wall of the bent clamping half tube A121. A wire hole A123 is opened at the middle end of the rubber semicircular pad A122. The number of wire tubes 111, clamping components 12 and shifting clamping components 13 are the same.

[0026] The clamping component 13 includes a bent clamp half tube B132 and a rubber semicircular pad B133 installed on the upper end of the inner wall of the bent clamp half tube B132. A wire hole B134 is opened in the middle of the rubber semicircular pad B133. Both the rubber semicircular pad B133 and the rubber semicircular pad A122 are sheet-like components made of polytetrafluoroethylene, which facilitates the protection of fiber optic patch cords.

[0027] A connecting strip 131 is installed on the outside of the bent clamp half tube B132, and one end of the connecting strip 131 is installed on the outer surface of the swivel ring 17. A threaded hole B135 is opened at the top of the connecting strip 131, and a threaded hole A118 is opened at the top of the cable clamping disc 116. A fixing bolt 14 is threaded inside the threaded hole A118, and the fixing bolt 14 is used to fix the cable clamping disc 116 and the moving clamping component 13.

[0028] A torsion spring 153 is installed at the bottom of the limiting plate 152, and the bottom end of the torsion spring 153 is installed at the top of the lower limiting ring 114. The torsion spring 153 is used to limit the range of rotation of the middle rod member 15.

[0029] In this embodiment: When installing the fiber optic patch cord between the fiber optic patch cord and the clamping structure 1, one end of the fiber optic patch cord is inserted into the lower bundle member 16, then into the conduit 111, and removed from the wire hole A123. One end of the fiber optic patch cord is then secured in the slot 117. The fiber optic patch cord is then pressed tightly against the outer surface of the rotating tube 151. After assembling multiple fiber optic patch cords according to the above operation, the rotating ring 17 is rotated, and the connecting strip 131 drives the bent clamp half tube B132 to move to one side of the bent clamp half tube A121. The rubber semi-circular pad B133 with the wire hole B134 contacts one side of the fiber optic patch cord. After the threaded hole B135 is aligned with the connecting bolt 115, the fixing bolt 14 is used to fix the position between the clamping plate 116 and the connecting strip 131. At this time, the bent clamp half tube A121 is not in contact with the bent clamp half tube B132, and the rubber semi-circular pad B13... 3. Without contact with the rubber semicircular pad A122, the position of the patch cord connector is constrained by the rubber semicircular pad B133 and the rubber semicircular pad A122. When the rotating tube 151 rotates, the rotating tube 151 drives the fiber optic patch cord to move together through the clamping plate 116, the fixing bolt 14 and the connecting strip 131. The patch cord connector lifts up one side of the contacting rubber semicircular pad B133, and the fiber optic patch cord is subjected to tension and bends to a certain extent. At this time, the fiber optic patch cord applies force to the rubber semicircular pad A122 at the same time, and the rubber semicircular pad A122 deforms, avoiding excessive bending of the fiber optic patch cord. The rubber semicircular pad A122 presses down on one side of the top of the patch cord connector. The rubber semicircular pads A122 and B133 can still constrain the patch cord connector. When the rotating tube 151 rotates, the limiting plate 152 is constrained by the torsion spring 153, which restricts the direction of rotation and avoids damage to the fiber optic patch cord.

[0030] Example 2: This example is an improvement upon Example 1. For details, please refer to [link / reference]. Figure 3 The lower bundle member 16 includes an externally threaded tube 161 and a rubber pad 162 installed at the bottom of the internal part of the externally threaded tube 161. A wire through hole 163 is provided through the middle of the rubber pad 162. A cross groove 164 is provided through the outside of the wire through hole 163 and on the surface of the rubber pad 162. The wire through hole 163 facilitates the placement of fiber optic patch cords, and the cross groove 164 facilitates the placement of thicker fiber optic patch cords.

[0031] In this embodiment: After the patch cord connector enters the conduit 111, the external threaded tube 161 can be rotated into the conduit 111 with the threaded groove 112. The depth of the external threaded tube 161 into the conduit 111 is adjusted according to the length of the patch cord connector. When the top of the rubber pad 162 contacts the bottom of the patch cord connector, the rotation of the external threaded tube 161 can be stopped. Since the rubber semicircular pad A122 and the rubber semicircular pad B133 do not contact each other when the clamping member 13 and the lower bundle member 16 are fixed, the clamping structure 1 can clamp the thicker fiber optic patch cord during use. Both the rubber semicircular pad A122 and the rubber semicircular pad B133 can deform. When the thicker fiber optic patch cord passes through the wire through hole 163, the rubber pad 162 with the cross groove 164 can continue to deform, which is convenient for accommodating the thicker fiber optic patch cord.

[0032] Working principle: Multiple fiber optic patch cords are passed through the lower bundle member 16, inserted into the conduit 111 and the slot 117, and pressed tightly against the outer wall of the duct 151. The connecting strip 131 drives the bent clamp half tube B132 to move to one side of the bent clamp half tube A121. The rubber semicircular pads B133 and A122 constrain the position of the patch cord connector. When the duct 151 rotates, the rubber semicircular pads A122 and B133 constrain the patch cord connector, and the rubber semicircular pad A122 deforms, preventing the fiber optic patch cord from bending excessively.
