Description

Technical Field

[0001] This utility model relates to the field of optical equipment technology, specifically to a winding card and an OTDR emission delay.

[0002] Long cable mounting box. Background Technology

[0003] An OTDR transmit extension cable is a specific function fiber optic extension cable and is widely used in the testing of optical fiber communication cables. Together with an OTDR (Optical Time Domain Reflectometer), it is an important auxiliary tool for testing the quality, loss, and fault location (bends, breaks, etc.) of the tested section of the optical cable by utilizing the principle of light scattering.

[0004] The technical reason for using an OTDR transmitter extension cable: When testing optical cables with an OTDR instrument, there is an inherent "blind zone," which varies depending on the accuracy and brand of the OTDR instrument. Specifically, there is a section of 1 to 10 meters, or even tens of meters, at both the near and far ends of the optical cable under test, where its quality and fault location cannot be determined. By connecting both ends of the OTDR transmitter extension cable to the OTDR and the optical cable under test respectively, this "blind zone" is cleverly transferred to the range of the external optical cable, thus ensuring that the entire length of the optical cable under test is within a stable testing range.

[0005] Existing OTDR transmitter extension cables typically need to be fixed to a winding device. However, the reliability of existing winding devices in fixing OTDR transmitter extension cables is not high, leading to messy winding and reducing the lifespan of the OTDR transmitter extension cables. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, the purpose of this utility model is to provide a winding clip and...

[0007] The OTDR transmitter extension cable mounting box uses a cable clamp plate to hold the cable harness and wrap it around two sets of winding sections. The winding sections limit the horizontal movement of the cable harness, and the adjustable cable fixing sections bind the cable harness, thereby limiting its vertical movement. This cable clamp plate structure ensures that the cable harness is stably and reliably fixed on it, which can greatly improve the service life of the cable harness.

[0008] To achieve the above objectives, this utility model provides a winding clip, a winding plate, two sets of winding portions, and two sets of adjustable wire-fixing portions. The two sets of winding portions are arranged opposite to each other on the winding plate. The two sets of winding portions cooperate to wind the wire harness and limit the horizontal movement of the wire harness. The two sets of adjustable wire-fixing portions are arranged opposite to each other on the winding plate and located between the two sets of winding portions. The adjustable wire-fixing portions are used to bind and fix the wire harness and limit the vertical movement of the wire harness. The adjustable wire-fixing portions can adjust the binding diameter.

[0009] Furthermore, the winding section includes a winding post and a limiting plate. One end of the winding post is disposed on the wire clamping plate for winding the wire harness. The limiting plate is fixed to the other end of the winding post and protrudes outward from the end of the winding post. A slot for clamping the wire harness is formed between the limiting plate and the wire clamping plate. When the wire harness is wound on the winding post, the wire harness is located in the slot, and the vertical movement of the wire harness is limited by the slot.

[0010] Furthermore, the adjustable cable fixing part includes a mounting plate and a strap. The mounting plate has a movable connecting seat on one side and a strap adjusting seat on the other side. The strap adjusting seat has a strap through hole through which the strap can pass.

[0011] One end of the strap is movably connected to the movable connecting seat, and the other end is inserted through the strap hole. The strap can form a fixing hole for bundling the wire harness. By pulling the free end of the strap, the strap can move in the strap hole and the diameter of the fixing hole can be adjusted.

[0012] Furthermore, the strap and the mounting plate are provided with corresponding snap-fit ​​structures. After the diameter of the fixing hole of the strap is adjusted, the strap and the mounting plate are engaged to fix the strap.

[0013] Furthermore, the strap adjustment seat consists of two L-shaped connectors, which are symmetrically arranged and form a strap through hole between them.

[0014] To achieve the above objectives, this utility model also provides an OTDR transmitter extension cable mounting box, including a box body and a winding clip as described above.

[0015] The winding clip is housed inside the housing. The clip plate vertically divides the housing into a placement area and a winding area. The placement area allows the OTDR transmitter extension cable to be placed there, with both ends of the OTDR transmitter extension cable passing through the clip.

[0016] The board enters the placement area and is wound around the winding section, and the adjustable fixing section binds and fixes the OTDR transmission extension cable.

[0017] Furthermore, the box body is composed of a box body 410 and a box lid, one end of which is movably connected to the box body, and the other end is detachably connected to the box body.

[0018] Furthermore, the wire clamping plate is connected to the inner surface of the box body, the vertical height of the winding post on the wire clamping plate is lower than the opening end of the box body, and the vertical height of the limiting plate is higher than the opening end of the box body.

[0019] Furthermore, the end face of the lid is provided with an edge, and the opening end of the box body is provided with a groove. A sealing ring is placed in the groove. When the lid is rotated relative to the box body to close, the edge is inserted into the groove and abuts against the sealing ring to achieve a seal between the lid and the box body.

[0020] Furthermore, the lid has a groove on the end face corresponding to the body of the box, and an elastic pad is provided in the groove. When the lid and the body of the box are rotated to close, the elastic pad can squeeze the winding area and limit the OTDR transmission extension line located in the winding area through the squeezing force.

[0021] The wire-winding clip and OTDR transmitter extension cable mounting box provided by this utility model, by placing the wire harness on the wire-winding plate and winding it around two sets of winding parts, limits the horizontal movement of the wire harness through the winding parts, and then binds the wire harness through the adjustable wire-fixing parts, thereby limiting the vertical movement of the wire harness. The wire-winding plate with this structure can stably and reliably fix the wire harness on it, which can greatly improve the service life of the wire harness.

[0022] Furthermore, by setting up a well-sealed and portable storage box to house the wire harness, the service life and portability of the wire harness can be further improved. Attached Figure Description

Detailed Implementation

[0032] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0033] See Figures 1-4 The diagram shown is a structural schematic of the winding card provided by this utility model.

[0034] As shown in the figure, the winding clip provided by this utility model includes three components: a wire clamping plate 100, two sets of winding parts 200, and two sets of adjustable wire fixing parts 300.

[0035] The cable tray 100 is the main structural component, used to support other parts.

[0036] Two sets of winding sections 200 are arranged opposite to each other on the wire clamping plate 100. The two sets of winding sections 200 cooperate to wind the wire harness and limit the horizontal movement of the wire harness.

[0037] Two sets of adjustable wire fixing parts 200 are disposed opposite to each other on the wire clamping plate 100 and located between the two sets of winding parts 200. The adjustable wire fixing parts 200 are used to bind and fix the wire harness, can limit the vertical movement of the wire harness, and can adjust the binding diameter to accommodate wire harnesses of various diameters.

[0038] Compared to existing technologies, this solution sets the wire harness on the wire clamping plate 100 and wraps it around two sets of winding sections 200. The winding sections 200 limit the horizontal movement of the wire harness, and the adjustable wire fixing section 300 binds the wire harness, thereby limiting the vertical movement of the wire harness. The wire clamping plate with this structure can stably and reliably fix the wire harness on it, which can greatly improve the service life of the wire harness.

[0039] The following description, in conjunction with the accompanying drawings, details each component of this solution.

[0040] like Figure 1 The cable tray 100 is plate-shaped and is used to carry the cable harness.

[0041] The winding section 200 includes a winding post 210 and a limiting plate 220. One end of the winding post 210 is disposed on the wire clamping plate 100 for winding the wire harness. The limiting plate 220 is fixed to the other end of the winding post 210 and protrudes outward from the end of the winding post 210. A slot for clamping the wire harness is formed between the limiting plate 220 and the wire clamping plate 100. When the wire harness is wound on the winding post 210, the wire harness is located in the slot, and the vertical movement of the wire harness is limited by the slot.

[0042] The winding section 220 with this structure cooperates with the adjustable wire fixing section 300. The winding section 220 provides horizontal constraint to the wire harness, and the adjustable wire fixing section 300 provides vertical constraint to the wire harness.

[0043] Specifically, such as Figure 2 , Figure 3 The adjustable cable fixing part 300 includes a mounting plate 310 and a strap 320. The mounting plate 310 has a movable connecting seat 330 on one side and a strap adjusting seat 340 on the other side. The strap adjusting seat 340 has a strap through hole 350 through which the strap 320 can pass.

[0044] One end of the strap 320 is movably connected to the movable connector 330, and the other end is inserted into the strap through hole 350. The strap 320 can form a fixing hole for bundling the wire harness. By pulling the free end of the strap 320, the strap 320 can move in the strap through hole 350, and the diameter of the fixing hole can be adjusted.

[0045] The strap 320 and the mounting plate 310 are provided with corresponding snap-fit ​​structures. After the diameter of the fixing hole of the strap 320 is adjusted, the strap 320 and the mounting plate 310 are engaged to fix the strap 320.

[0046] Furthermore, in this example, the movable connecting seat 330 is specifically composed of two connecting seats 331 and a rotating shaft 332. The two connecting seats 331 are arranged opposite to each other on the cable clamping plate mounting plate 310. Both connecting seats 331 are provided with rotating holes. The two ends of the rotating shaft 332 are rotatably located in the rotating holes. The rotating shaft 332 is connected to the end of the strap 320.

[0047] The rotating shaft 332 rotates in the rotating hole, thereby driving the strap 320 connected to it to rotate.

[0048] Furthermore, in this example, the strap 320 and the mounting plate 310 are preferably provided with corresponding snap-fit ​​structures:

[0049] The strap 320 has a number of connecting holes 321 arranged in sequence along its length. The mounting plate 310 has a connector 311 corresponding to the connecting holes 321. By fitting any one of the connecting holes 321 onto the connector 311, the strap 320 is connected to the mounting plate 310.

[0050] Furthermore, such as Figure 4 The strap adjustment seat 340 consists of two L-shaped connectors 341, which are symmetrically arranged and form a strap through hole 350 between them.

[0051] This utility model also provides an OTDR transmitter extension cable mounting box, which can accommodate the OTDR transmitter extension cable, and includes the aforementioned winding clip, which has all the characteristics of the winding clip.

[0052] The OTDR transmitter extension cable is housed in a mounting box and wound around a cable clip for secure mounting. The mounting box improves the portability of the OTDR transmitter extension cable and further extends its lifespan.

[0053] like Figure 5 The OTDR transmitter extension cable mounting box provided by this utility model includes a box body 400, as described above, and a winding clip.

[0054] The cable winding clip is installed inside the housing 400. The cable clamp plate 100 vertically divides the housing into a placement area and a winding area. The placement area is where the OTDR transmitter extension cable can be placed. Both ends of the OTDR transmitter extension cable pass through the cable clamp plate 100 into the placement area and are wound around the winding part 200. The adjustable cable fixing part 300 binds and fixes the OTDR transmitter extension cable.

[0055] Furthermore, the box body 400 is composed of a box body 410 and a box cover 420. One end of the box cover 420 is movably connected to the box body 410, and the other end is detachably connected to the box body 410.

[0056] The box 400 with this structure can be opened and closed by rotating the lid 420 relative to the box body 410, and can be locked and unlocked by being detachably connected to the box body 410.

[0057] Furthermore, the cable clamping plate 100 is connected to the inner surface of the box body 410, the vertical height of the winding post 210 on the cable clamping plate 100 is lower than the opening end of the box body 410, and the vertical height of the limiting plate 220 is higher than the opening end of the box body 410.

[0058] To further improve the reliability of the box, the end face of the box cover 420 is provided with an edge 421, and the opening end of the box body 410 is provided with a slot 411. A sealing ring is placed in the slot 411. When the box cover 420 is rotated to close relative to the box body 410, the edge 421 is inserted into the slot 411 and abuts against the sealing ring, thereby achieving a seal between the box cover 420 and the box body 410.

[0059] Furthermore, the cover 420 has a groove on the end face corresponding to the body 410, and an elastic pad 422 is provided in the groove. When the cover 420 and the body 410 are rotated to close, the elastic pad 422 can squeeze the winding area and limit the OTDR transmission extension line located in the winding area through the squeezing force.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
