Description

Technical Field

[0001] This utility model relates to the field of optical cable testing technology, specifically to a stranded optical cable tensile testing device. Background Technology

[0002] Stranded optical cables consist of multiple sheaths containing optical fibers twisted together around a central reinforcing member to form a round cable core. Stranded optical cables require testing during production to ensure their reliability and durability during installation and use. Tensile testing is essential for stranded optical cables. This test measures the cable's ability to withstand tensile forces, confirming the rationality of its structure, its quality, and whether its strength meets design requirements. This helps ensure the cable can withstand various external forces and maintain stable transmission performance during use.

[0003] Tensile testing of stranded optical cables requires the use of a tensile testing device, such as those with announcement numbers CN215727279U or CN219641428U. Tensile force is applied to the optical cable sample at the set test speed, and the tensile force is recorded. When the optical cable sample reaches the specified tensile strength or breaks, the device is stopped. The tensile force value at this time is used as the test result of the optical cable's tensile strength and elongation at break, among other performance indicators.

[0004] Currently, when optical cables break, the resulting debris flies outwards and lands directly on workbenches or even the ground, increasing the workload for cleaning personnel. Utility Model Content

[0005] Therefore, this utility model provides a stranded optical cable tensile testing device, which conducts the optical cable tensile test within the space enclosed by the outer cover and the base plate. During the test, the debris generated by the optical cable breakage is located inside the outer cover and will not splash outward, reducing the workload of the staff in cleaning.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a stranded optical cable tensile testing device, comprising a frame and a support frame fixed to the top of the frame, wherein the support frame is provided with a testing component, the testing component comprising a linear module fixed to the top of the support frame and a protective component disposed at the bottom of the linear module.

[0007] The protective assembly includes an outer cover, inside which are two sets of clamps for fixing the stranded optical cable to be tested. One set of clamps is fixed to the outer cover, and the other set of clamps can move inside the outer cover. A base plate is hinged to the bottom of the outer cover.

[0008] Furthermore, the clamp includes an n-shaped base and a clamping plate slidably disposed within the n-shaped base. A housing is fixed to the front side of the n-shaped base, and an electric push rod is fixed inside the housing. The piston rod of the electric push rod is fixed to the clamping plate to drive the clamping plate to move and clamp the stranded optical cable to be tested.

[0009] The ANT-26 electric actuator is selected, which has a perfect combination of size and thrust. Its small size makes it the first choice for products with limited installation space. It has a high waterproof and dustproof rating, strong self-locking force, can be stopped at will during operation, and has strong resistance to environmental temperature.

[0010] Furthermore, one set of clamps has its n-shaped seat fixedly connected to the inner wall of the outer cover, while the other set of clamps has its n-shaped seat movably connected to the outer cover wall.

[0011] Furthermore, one side of the n-shaped seat of a movable set of clamps is fixedly connected to the linear module via a pull rod, and a tension sensor is provided on the pull rod; the HDW301S type tension sensor is selected, and a computer for receiving and displaying tension sensor data is provided on the frame.

[0012] Furthermore, the rear side of the base plate is hinged to the rear side of the outer cover, and the front side of the base plate is snapped to the front side of the outer cover, which facilitates the opening and closing of the base plate.

[0013] Furthermore, a trimming assembly is provided on the rear side of the outer cover near a set of fixed clamps for trimming the end face of the stranded optical cable after testing; the trimming assembly includes an electric cylinder and a cutter fixed to the piston rod end of the electric cylinder. The electric cylinder is fixed on the support frame, and the cutter passes through the rear end of the outer cover and is slidably connected to the outer cover. The electric cylinder is an SDG32-001 linear electric cylinder.

[0014] Furthermore, a cable feeder is fixed to one side of the support frame at the top of the rack, and a collection box is placed at the bottom of the protective assembly at the top of the rack. The cable feeder is located on one side of the collection box. After the test, debris and broken optical cables are collected in the collection box.

[0015] This utility model has the following advantages:

[0016] 1. This device conducts tensile tests on stranded optical cables within the space enclosed by the outer casing and the base plate. When the optical cable breaks during the test, the debris generated when the optical cable breaks is contained within the outer casing and does not fly outward due to the obstruction of the outer casing and the base plate. After the test, the debris and broken optical cable are collected in a collection box, reducing the workload of the staff in cleaning.

[0028] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0029] Refer to the instruction manual appendix Figure 1-6 This utility model provides a tensile testing device for stranded optical cables, including a frame 1 and a support frame 2 fixed to the top of the frame 1. The support frame 2 is provided with a testing component, which includes a linear module 4 fixed to the top of the support frame 2 and a protective component 3 located at the bottom of the linear module 4. A collection box 7 is placed at the top of the frame 1 and at the bottom of the protective component 3.

[0030] Specifically, such as Figure 2-5As shown, the protective component 3 includes an outer cover 31, with a base plate 33 at its bottom. The rear side of the base plate 33 is hinged to the rear side of the outer cover 31, and the front side of the base plate 33 is snapped into place with the front side of the outer cover 31, facilitating the opening and closing of the base plate 33. The snap-fit ​​mechanism is used for the insertion and connection of one part to another or for overall locking, featuring convenient installation and disassembly. It allows for quick assembly and disassembly without tools and is widely used in various products, such as toys, electronic products, and automotive parts. Furthermore, to facilitate observation of the optical cable by staff, the outer cover 31 and the base plate 33 are made transparent.

[0031] The outer cover 31 is equipped with two sets of clamps 32 for fixing the stranded optical cable to be tested. The clamps 32 include an n-shaped base 321 and a clamping plate 322 slidably disposed in the n-shaped base 321. A shell 323 is fixed to the front side of the n-shaped base 321. An electric push rod 324 is fixed inside the shell 323. The piston rod of the electric push rod 324 is fixed to the clamping plate 322. When the optical cable is placed in the n-shaped base 321, the electric push rod 324 drives the clamping plate 322 to move. The optical cable can be clamped and fixed by the clamping plate 322 and the inner wall of the n-shaped base 321. In order to facilitate the observation of the optical cable by the staff, the n-shaped base 321 and the clamping plate 322 are made transparent.

[0032] One set of clamps 32 has an n-shaped seat 321 fixedly connected to the inner wall of the outer cover 31, that is, the clamp 32 on the left side is fixed to the outer cover 31, and the n-shaped seat 321 of the other set of clamps 32 is movably connected to the inner wall of the outer cover 31, that is, the clamp 32 on the right side can move inside the outer cover 31. One side of the n-shaped seat 321 of the movable set of clamps 32 is fixedly connected to the linear module 4 through a pull rod 34, and a tension sensor is provided on the pull rod 34.

[0033] The stranded optical cables tested by this device can be optical cable samples cut into small sections or optical cable products in rolls:

[0034] 1. When testing optical cable samples cut into small sections: Open the base plate 33, such as... Figure 6 As shown, the optical cable is placed into the outer cover 31 from the bottom, and then the two ends of the optical cable are fixed with two sets of clamps 32. Then, the base plate 33 is fastened to the bottom of the outer cover 31, and the pull rod 34 is pulled by the linear module 4 to move the clamp 32 on the right to the right, thereby pulling the optical cable until it breaks. At this time, the tensile force value of the tension sensor is the test result of the tensile strength and other performance indicators of the optical cable. Due to the obstruction of the outer cover 31 and the base plate 33, the debris generated when the optical cable breaks is located inside the outer cover 31 and will not fly outward. Then, the base plate 33 is opened and the clamps 32 are released. The debris and the broken optical cable fall into the collection box 7 for collection, which is convenient for the staff to clean up.

[0035] II. When testing rolled optical cable products, such as Figure 1As shown, a cable feeding frame 6 is fixed at the top of the frame 1 on one side of the support frame 2. The cable feeding frame 6 is located on one side of the collection box 7. A trimming component 5 is also provided on the rear side of the outer cover 31 near a set of fixed clamps 32. This component is used to trim the end face of the stranded optical cable after testing. The trimming component 5 includes an electric cylinder 51 and a cutter 52 fixed to the piston rod end of the electric cylinder 51. The electric cylinder 51 is fixed on the support frame 2. The cutter 52 passes through the rear end of the outer cover 31 and is slidably connected to the outer cover 31.

[0036] Place the rolled optical cable product on the cable feeding rack 6, open the bottom plate 33, pull out the movable end of the optical cable and put it into the outer cover 31 from the bottom of the outer cover 31. The right clamp 32 fixes the movable end of the optical cable, and the left clamp 32 fixes the section of optical cable that is located inside it at this time. Then, according to the above test steps, perform a tensile test on the section of optical cable between the two sets of clamps 32.

[0037] After the test, a section of optical cable between the two sets of clamps 32 broke. Then, the electric cylinder 51 was started to drive the cutter 52 to move forward and cut off a section of optical cable on the right side of the left clamp 32. At this time, the movable end of the optical cable was trimmed. Then, the base plate 33 was opened, the clamp 32 was released, and the debris and broken optical cable fell into the collection box 7 for collection. Then, the coiled stranded optical cable was removed.

[0038] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
