Description

Technical Field

[0001] The utility model relates to the technical field of voltage probes, in particular to an optical isolation voltage probe. Background Art

[0002] An optically isolated voltage probe is a specialized measurement probe used in oscilloscope measurements. Its operating principle is to convert a high-bandwidth electrical signal acquired at the front end into laser light, which is then transmitted to the back end via optical fiber. The laser light is then converted back into an electrical signal, achieving complete electrical isolation between the input and output signals. The probe primarily consists of an optical converter and an optical-to-electrical converter. This process achieves complete electrical isolation between the input and output signals through electrical-to-optical-to-electrical conversion.

[0003] However, in the existing technology, most converters and optical cable connecting lines are connected to each other and then the probe is connected to the device before detection can be carried out.

Although it can be used, the stability is low and the line may become entangled during use, which greatly affects the subsequent detection use. For this reason, we have proposed an optically isolated voltage probe to solve the above problems. Utility Model Content

A non-slip pad is provided on the upper end of the outer wall of the pressure block 6, and it is against the upper side of the inner wall of the turntable 1. This structure can wrap the cable 4 so that it is on the surface of the fixed disk 2 for surrounding and contracting.

[0022] Furthermore, pads 12 are provided on both sides of the inner wall of the turntable 1, and the surface of the pads 12 is set to an inclined surface. The material of the pads 12 is set to rubber material. The surface of the pads 12 fits the surface of the converter 13. This structure can plug the converter 13 into a position that matches the surface of the pads 12, so that the converter 13 can be placed stably.

[0023] Furthermore, the clamping includes a slide groove 14, a fixed groove 10 is provided at the upper end of the turntable 1, and the middle of the inner wall of the fixed groove 10 is connected to the movable plate 11 through a rotating shaft, and the inner wall of the fixed groove 10 and the surface of the movable plate 11 are provided with an anti-slip pad, and a slide groove 14 is provided on the inner upper side of the movable plate 11, and a bidirectional screw 15 is connected to the middle of the inner wall of the slide groove 14 through a bearing, and the left end of the bidirectional screw 15 is fixedly connected to a torsion block 16, and the surface of the bidirectional screw 15 is connected to a screw sleeve 21 through a thread, and the upper end of the surface of the screw sleeve 21 is fixedly connected to a splint 17, and a plurality of groups of heat dissipation holes 18 are equidistantly provided on the surface of the splint 17.
