An oscilloscope probe with automatic beam alignment

Abstract

This utility model relates to the field of oscilloscope probe technology, specifically disclosing an automatic cable-bearing oscilloscope probe, including a fixed rod disposed within a sleeve, an elastic component sleeved on the fixed rod, a grounding component connected to the elastic component, a probe rod threaded to the bottom of the fixed rod, a limiting rod disposed on the elastic component, a through hole disposed on the limiting rod, a top plate fixedly connected to the top of the limiting rod, multiple wedge-shaped limiting blocks disposed on the top plate, a cable-bearing head slidably connected to the bottom of the limiting rod, a rubber spring sleeved on the limiting rod, and multiple fixing blocks disposed on the probe rod. The shape of the fixing blocks is adapted to the opening of the fixing holes, allowing the fixing blocks to be embedded into the fixing holes in a preset direction. When the grounding component is used, the cable-bearing head rotates, causing the spring to deform. After use, the grounding component is released, the spring returns to its deformation, and the cable-bearing head rotates, causing the grounding component to reset, so that the grounding component can always remain suspended during use.

Description

Technical Field

[0001] This utility model relates to the field of oscilloscope measurement, specifically to an oscilloscope probe with automatic wire rigging. Background Technology

[0002] Oscilloscopes are core instruments in the field of electronic measurement. Their main function is to convert electrical signals into visual waveforms, intuitively presenting the amplitude, frequency, phase and other characteristics of the signal. They can also measure parameters such as pulse width, rise time and phase difference, helping engineers analyze signal integrity and troubleshoot circuit faults. They are widely used in fields such as communications, power, and electronic research and development.

[0003] When using the device, first connect the probe to the circuit under test and ensure that the grounding clamp is reliably grounded. Then turn on the device, set the trigger source and trigger mode, and adjust the time base knob and vertical gain knob until the waveform is stably displayed in the center of the screen. If measurement parameters are required, the values ​​can be read through the cursor function or the automatic measurement menu.

[0004] Before starting testing, the oscilloscope needs to be grounded to check the signal amplitude. During normal measurements, the grounding device needs to be kept suspended to prevent potential short circuits or other dangerous situations. This not only threatens the safety of the instrument and the test personnel but also leads to deviations in the measurement results. However, existing grounding devices usually only use wires to connect the probe and do not have a dedicated grounding device. Users need to choose the placement position themselves to ensure that the grounding device is suspended, which poses certain safety hazards.

[0005] To address these shortcomings, an oscilloscope probe with automatic wire-laying is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an oscilloscope probe with automatic wire retraction. By designing an elastic component housed in a sleeve, the grounding component can be automatically retracted through the elastic component during use, thus solving the problem that the lack of a specially designed safe suspended position for the grounding component may lead to deviations in measurement results.

[0007] To achieve the above objectives, this utility model provides an oscilloscope probe with automatic cable rigging, comprising a sleeve, characterized in that: a fixed rod is provided inside the sleeve, an elastic component is sleeved on the fixed rod, a grounding component is wire-connected to the elastic component, a probe rod is threaded to the bottom of the fixed rod, a limiting rod is provided on the elastic component, a through hole is provided on the limiting rod, a top plate is fixedly connected to the top of the limiting rod, a plurality of wedge-shaped limiting blocks are provided on the top plate, a cable rigging head is slidably connected to the bottom of the limiting rod, and a rubber spring is sleeved on the limiting rod.

[0008] As a preferred technical solution of this utility model, the front of the outer shell is provided with a first threaded hole, and the probe rod is provided with multiple fixing blocks. The shape of the fixing blocks is adapted to the opening of the fixing hole, so that the fixing blocks can be embedded in the fixing hole in a preset direction.

[0009] As a preferred technical solution of this utility model, a limiting hole is provided in the sleeve, and the elastic component is connected to the sleeve by a limiting block engaging with the limiting hole.

[0010] As a preferred technical solution of this utility model, one end of the rubber spring is fixedly connected to the top of the top plate, and the other end of the rubber spring is fixedly connected to the wire harness head.

[0011] As a preferred technical solution of this utility model, the top plate and the limiting rod are integrally molded injection parts.

[0012] As a preferred technical solution of this utility model, the grounding component is provided with a rubber sleeve, a grounding clamp is provided inside the rubber sleeve, an anti-slip texture is provided on one side of the rubber sleeve, and a fixing hole is provided in the center of the anti-slip texture.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention incorporates an elastic component within a sleeve, with the grounding component fixed to it. When the grounding component is in use, the rubber spring within the elastic component deforms under stress. After use, the grounding component automatically retracts via the rubber spring and is secured by a fixing block on the probe rod and a fixing hole on the grounding component, thus suspending the grounding component. This prevents dangerous situations such as short circuits caused by the grounding component not being suspended, making the use of the oscilloscope safer. Attached Figure Description

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] This utility model provides a technical solution: an oscilloscope probe with automatic cable routing. A fixing rod 11 is provided inside a sleeve 1. An elastic component 4 is sleeved on the fixing rod 11. The elastic component 4 is wire-connected to a grounding component 3. The grounding component 3 has a rubber sleeve 33. A grounding clamp is provided inside the rubber sleeve 33. An anti-slip texture 31 is provided on one side of the rubber sleeve 33. A fixing hole 32 is opened in the center of the anti-slip texture 31. The bottom of the fixing rod 11 is threadedly connected to a probe rod 2. The elastic component 4 has a limiting rod 44. The limiting rod 44 has a through hole 46. A top plate 42 is fixedly connected to the top of the limiting rod 44. The top plate 42... Multiple wedge-shaped limiting blocks 41 are provided. The bottom end of the limiting rod 44 is slidably connected to the wire harness head 45. The limiting rod 44 is fitted with a rubber spring 47. The probe rod 2 is provided with multiple fixing blocks 21. The shape of the fixing block 21 is adapted to the opening of the fixing hole 32, so that the fixing block 21 can be embedded in the fixing hole 32 in a preset direction. A limiting hole is opened in the sleeve 1. The elastic component 4 is connected to the sleeve 1 through the limiting block 41 and the limiting hole.
