Current Meter with Receiving Grooves for Moisture-Proof Line Insertion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing current meters require disconnection of electrical lines for attachment, making them cumbersome and difficult to seal moisture-proof for outdoor use, especially when monitoring string currents in solar installations.
Innovation Solution
A current meter with receiving grooves on the housing wall for external insertion of electrical lines, enclosing magnetic field sensors inside the housing to detect currents without opening the housing, ensuring moisture-proof sealing and allowing for easy retrofitting and outdoor use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electrical lines are placed between housing halves for current detection, then current monitoring function is achieved, but housing sealing against moisture becomes difficult
Solution Approach 1:
The housing is divided into two separable halves with receiving grooves that allow electrical lines to be inserted from the outside. This segmentation enables the housing to remain sealed against moisture while still allowing line insertion through the groove structure without compromising the seal.
2Ease of operation
If housing halves are disconnected for line attachment, then electrical lines can be inserted, but attachment process becomes cumbersome and complex
Solution Approach 1:
The receiving grooves are pre-formed on the housing wall during manufacturing, allowing electrical lines to be directly inserted into the grooves from the outside without requiring disconnection of housing halves. This preliminary preparation of the housing structure simplifies the attachment process significantly.
3Object-affected harmful factors
If housing is sealed moisture-proof, then outdoor use is enabled, but line insertion from outside becomes difficult
Solution Approach 1:
The receiving grooves are designed as recesses in the housing wall that allow electrical lines to be inserted from the outside while maintaining the sealed structure. The groove configuration enables line access without creating openings that would compromise the moisture seal.

AI summary
A current meter for detecting currents in electrical lines includes: a housing having a plurality of receiving grooves formed on a housing wall, into which receiving grooves an electrical line is in each case insertable from outside the housing; and an arrangement of magnetic field sensors enclosed in the housing. The arrangement of magnetic field sensors detects a magnetic field on electrical lines inserted into the receiving grooves. The housing encloses an interior delimited by the housing wall, inside which interior the arrangement of magnetic field sensors is arranged.
