Description

Technical Field

[0001] This utility model relates to the field of electrical instrumentation technology, specifically a portable electrical instrumentation. Background Technology

[0002] Portable electrical instruments are commonly used tools in electrical testing operations. However, existing products have several shortcomings: poor protection, as internal components are easily damaged by collisions and bumps during transport, affecting their lifespan; test leads, as key components, lack a reasonable storage structure, are easily lost or tangled after use, requiring time to organize them before the next use, reducing work efficiency; and the overall structure of the instruments is not compact or portable enough, taking up a lot of space and making it inconvenient for electricians to carry to different work locations. Their use is significantly limited in scenarios such as working at heights or in confined spaces, affecting their practicality and user experience. Utility Model Content

Two sets of fixing brackets are symmetrically fixedly connected to the front end of the inner side wall of the rear housing. Each set of fixing brackets consists of two brackets arranged symmetrically from top to bottom. The rear cover is fixedly snapped into the rear opening of the rear housing.

[0009] The detection component includes a multimeter head fixedly installed in the front housing. A control feedback component is provided at the front end of the multimeter head, and a probe assembly is provided at the bottom end of the multimeter head. The probe assembly includes probe bodies that are respectively fixedly snapped into two sets of fixed brackets.

[0010] As a further improvement of this utility model: a damping shaft is fixedly connected to each of the upper ends of the front housing, and damping holes are opened at both ends of the front cover for the damping shaft to rotate and assemble, so that the front cover can rotate and open and close stably and controllably, improving protection and ease of operation.

[0011] As a further improvement of this utility model: the multimeter head has a built-in lithium battery, and a matching charging interface is provided at the bottom center of the multimeter head, which facilitates instrument charging, ensures battery life, and improves portability.

[0012] As a further improvement of this utility model: the multimeter head is provided with probe interfaces on both sides of the bottom end, and the probe assembly includes a probe connector inserted into the probe interface, so as to realize convenient connection and disassembly of the probe and the meter head.

[0013] As a further improvement of this utility model: the probe connector is connected to the probe body on its corresponding side by a probe wire, and the probe wire is located inside the front and rear housings, which not only neatly stores the probe wire, but also avoids its exposure and damage, thus improving the structural compactness.

[0016] 1. In this utility model, by setting an external protective component, the front shell, rear shell, front cover, and rear cover together constitute a protective structure, providing physical protection for the internal detection components. During the carrying, transportation, and operation of the instrument, it effectively resists collisions and bumps, reduces the risk of damage to internal components, and extends the service life of the instrument. At the same time, the front cover is rotated and assembled with the front shell through a damping shaft, which makes the opening and closing stable and can be stopped as needed, making it highly convenient to operate. It can be quickly opened when the instrument is in use and reliably closed when not in use, ensuring the protective effect.

[0017] 2. In this utility model, by setting a probe assembly and a corresponding fixing bracket in the detection component, the probe body is snapped onto the fixing bracket on the inner side of the rear housing, thus achieving orderly storage of the probes and avoiding the problems of loss or tangling. The probe wires are stored neatly in the front and rear housings and are not easily damaged. When in use, the probe connector and probe interface can be quickly plugged in to start work, improving work efficiency. Moreover, the overall structure is compact, and the outer protective component and detection component are reasonably arranged, reducing the space occupied by the instrument, making it easy for electricians to carry with them, adapting to various work scenarios, and improving portability and practicality.
