Universal measuring instrument supporting hot plug probes

Abstract

This invention proposes a universal measuring instrument supporting hot-swappable probes, including a body and a digital display screen. The digital display screen is mounted on the front of the body, and an inner sleeve is mounted on the end face of the body. An outer sleeve is fixedly connected to the port of the inner sleeve, and the inner diameter of the inner sleeve is smaller than the inner diameter of the outer sleeve. The advantages of this invention are: it ensures that the connector can only be inserted in the correct direction, thus improving safety. A ring of magnetic plates is fixedly connected to the end face of the inner sleeve, guiding alignment through magnetic force, reducing mechanical wear, and improving contact reliability. The design of the sleeve, spring, and probe structure, with the elasticity of the spring, ensures high elasticity contact between the probe and the connector, withstanding frequent insertion and removal, and maintaining a stable electrical connection even under frequent insertion and removal. This significantly improves connection reliability and reduces failures caused by poor contact or misinsertion.

Description

Technical Field

[0001] This utility model relates to the field of measuring instrument technology, and in particular to a general-purpose measuring instrument that supports hot-swappable probes. Background Technology

[0002] Many measuring instruments now support hot-swapping, such as temperature measuring equipment, where the probe connector can be hot-swapped from the body. The advantage is that hardware replacement can be performed without restarting the system, significantly reducing system downtime. This greatly simplifies maintenance processes and avoids time losses due to system downtime or restarts. In applications requiring frequent probe replacements, hot-swapping can significantly improve work efficiency.

[0003] However, frequent hot-swapping of probes also brings a series of problems. First, frequent mechanical wear between the probe connector and the instrument can damage the connector. Frequent plugging and unplugging can also cause the connection between the connector and the instrument to become loose and unstable. Therefore, a general-purpose measuring instrument that supports hot-swappable probes is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to propose a universal measuring instrument that supports hot-swappable probes, so as to solve the problems mentioned in the background art and overcome the shortcomings of the prior art.

[0006] To achieve the above objectives, one embodiment of the present invention provides a general-purpose measuring instrument that supports hot-swappable probes, including a body and a digital display screen. The digital display screen is mounted on the front of the body, and an inner sleeve is mounted on the end face of the body. An outer sleeve is fixedly connected to the port of the inner sleeve.

[0007] The inner diameter of the inner sleeve is smaller than the inner diameter of the outer sleeve, and a key block is fixedly connected to the top of the inner side of the outer sleeve;

[0008] A ring of magnetic sheets is fixedly connected to the end face of the inner sleeve, and a sleeve is fixedly connected to the inner side of the inner sleeve.

[0009] A probe is movably connected inside the sleeve, and a spring is fixedly connected between the inner end face of the probe and the end face of the inner side of the sleeve.

[0010] The inner and outer sleeves are fitted with connectors, and a cable is fixedly connected to the end of the connector. A probe is fixedly connected to the end of the cable. The magnetic sheet is attracted to one end of the connector, and the end of the probe abuts against the corresponding part of the connector.

[0011] Preferably, in any of the above solutions, the inner sleeve and the outer sleeve are heat-fused together, and the inner sleeve and the outer sleeve are interconnected.

[0012] The above technical solution utilizes a measuring instrument specifically designed for measuring the temperature of workpieces and equipment. A sensitive element (such as a thermocouple) is encapsulated within a probe, which contacts the object being measured to directly sense temperature changes. The sensitive element converts the temperature change into an electrical signal, which is then transmitted via cable to the measuring circuit for processing. The measuring circuit amplifies, filters, and converts the received electrical signal, ultimately outputting an electrical signal proportional to the temperature. This signal is then converted into a digital signal and displayed on a digital screen.

[0013] Preferably, the key block is elongated, as described in any of the above schemes.

[0014] By adopting the above technical solution, this instrument supports hot-swapping while powered on, which facilitates practical operation. It eliminates the need to shut down the power, thus simplifying the operation process and reducing downtime.

[0015] Therefore, auxiliary structures were designed: inner sleeve, outer sleeve, key block, magnetic sheet, sleeve, probe, spring, and connector.

[0016] Anti-misinsertion design: An asymmetrical outer sleeve structure is designed, with a key block fixedly connected to the top of the inner sleeve to ensure that the connector can only be inserted in the correct orientation, improving safety. A magnetic ring is fixedly connected to the end face of the inner sleeve, guiding alignment through magnetic force, reducing mechanical wear, and improving contact reliability. The sleeve, spring, and probe structure uses the spring's elasticity to ensure highly elastic contact between the probe and the connector, withstanding frequent insertion and removal, maintaining a stable electrical connection even under frequent insertion and removal. This significantly improves connection reliability and reduces failures caused by poor contact or misinsertion.

[0017] Preferably, of any of the above embodiments, the magnetic sheet is a ring with a notch, and the surfaces of the sleeve, probe, and spring are plated with gold.

[0018] Preferably, in any of the above schemes, the sleeve is arranged in a circumferential array about the axis of the inner sleeve, and the joint is designed to fit the two sections of the inner and outer sleeves.

[0019] Preferably, in any of the above embodiments, the outer surface of the connector has a notch for adapting to the key block, and the connector is movably connected to the key block.

[0020] Preferably, according to any of the above solutions, the advantages and beneficial effects of this utility model compared with the prior art are as follows:

[0021] This universal measuring instrument supporting hot-swappable probes employs an asymmetrical outer sleeve structure with an inner sleeve, outer sleeve, key block, magnetic plate, sleeve, probe, spring, and connector. A key block is fixedly connected to the top of the inner sleeve to ensure the connector can only be inserted in the correct orientation, improving safety. A magnetic plate is fixedly connected to the end face of the inner sleeve, guiding alignment with magnetic force, reducing mechanical wear, and improving contact reliability. The sleeve, spring, and probe structure utilizes the spring's elasticity to ensure highly elastic contact between the probe and connector, withstanding frequent insertion and removal, maintaining a stable electrical connection even under frequent insertion and removal. This significantly improves connection reliability and reduces failures caused by poor contact or misinsertion.
