Description

Technical Field

[0001] The utility model relates to the technical field of cable testing, in particular to a USB cable bending resistance testing device. Background Art

[0002] USB is an input and output interface that is widely used in information and communication products such as personal computers and mobile devices. The battery core inside the cable that connects to the USB interface is made of optical fiber. Optical fiber is easily bent and broken during use, resulting in signal transmission failure, so it needs to be bent during production.

[0003] The current testing method is to simply bend a single optical fiber cable and then measure it at the maximum bending angle. This bending measurement method cannot progressively reflect the maximum bending degree of the optical fiber cable, thus affecting the accuracy of the measurement. Summary of the Invention

[0005] In order to solve the above technical problems, the basic concept of the technical solution adopted by the present invention is:

[0006] A USB cable bending resistance testing device includes a base plate and a triangular support platform. The triangular support platform is arranged on the top of the base plate and is in the shape of a right triangle. The top of the triangular support platform is triangular in shape. A plurality of arc-shaped openings are equidistantly provided on the top of the triangular support platform. Slide grooves are provided on the top of the base plate near the front and rear edges. The bottoms of the two slide grooves extend to the outside of the base plate.

[0007] Optionally, guide plates are fixed to the bottom of the triangular support platform near the front and rear edges, and the two guide plates are correspondingly slidably connected to the inside of the sliding groove.

[0008] Optionally, a guide rod is fixed on the front side of the two guide plates, and the two guide rods extend from the slide groove to the outside of the base plate respectively. The outer surfaces of the two guide rods are threadedly connected with locking nuts, and the outer surfaces of one side of the two locking nuts are respectively in contact with the outer surface of the base plate.

[0009] Optionally, a plurality of electrical interfaces are equidistantly provided on both sides of the base plate, and a plurality of indicator lights are equidistantly provided on both sides of the base plate, and the plurality of indicator lights are correspondingly located above the electrical interfaces.

[0010] Optionally, terminal seats are fixed to the top of the base plate near the edges on both sides, and multiple docking ports are equidistantly opened on one side of the two terminal seats, and the multiple docking ports are correspondingly extended to the other side of the terminal seat.

[0011] Optionally, a plurality of clamping bolts are equidistantly arranged on the tops of the two terminal seats near the edges on both sides, and the bottoms of the plurality of clamping bolts pass through the interior of the docking interface.

[0012] Optionally, a copper gasket is fixed to the inner bottom surface of each of the docking interfaces near one side edge, a copper pressure plate is provided at the bottom of each of the clamping bolts near one side of the terminal seat, and each of the copper pressure plates is located above the copper gasket, and a rubber pressure block is provided at the bottom of each of the clamping bolts near the other side of the terminal seat.

[0013] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described below at the same time:

[0014] 1. In the present invention, the triangular support platform is arranged in a right-angled triangle shape, and the top of the triangular support platform is arranged in a triangular shape. The bottom of the triangular shape at the top of the triangular support platform extends toward the front side of the triangular support platform, so that the cross-sectional area of ​​the top of the triangular support platform near the front side is wider than that near the rear side. At this time, the cable to be bent is bent through the top of the triangular support platform. When bending, the bending angle of the cable located at the top of the triangular support platform becomes larger from front to back, which makes it easy for people to intuitively see whether different bending angles have an effect on the cable during testing.

[0015] 2. In the utility model, when the bending angle has no effect on the cable, the corresponding indicator light will light up. When the bending angle is large and the cable is damaged, the corresponding indicator light will go out. When fixing the cable, the two ends of the cable are respectively inserted into the terminal blocks on both sides of the bottom plate. The cable ends are pressed tightly by rubber pressure blocks inside the docking interface to prevent them from falling off.
