Flexible Testing Solutions for Terminal Block Assemblies
Here’s PatSnap Eureka !
Summary
Problems
Existing testing devices for terminal block assemblies are limited in their ability to test electrical circuits from different locations, particularly requiring modifications when testing from below the assembly, which restricts flexibility and versatility in automation and other applications.
Innovation solutions
A testing arrangement that allows the testing device to be connected to terminal block assemblies from either the upper or lower side, utilizing insulating test plugs and dummy plugs to disconnect contact pairs, with leaf spring contacts and pressure springs ensuring electrical isolation and easy plugging without additional constructive adaptations, and featuring adjustable protective covers and mounting options for varied use.
TRIZ Analysis
Specific contradictions:
General conflict description:
Principle concept:
If the testing device is arranged above the terminal block assembly, then the testing operation can be performed, but the accessibility is limited and cannot test from lower surface when mounted in wall opening
Why choose this principle:
The terminal block assembly is segmented into multiple independently testable units, each with its own testing device that can be connected from either upper or lower side. This segmentation allows flexible testing arrangements where each terminal block can be tested independently from the most accessible direction, resolving the contradiction between testing accessibility and device complexity.
Principle concept:
If the testing device is arranged above the terminal block assembly, then the testing operation can be performed, but the accessibility is limited and cannot test from lower surface when mounted in wall opening
Why choose this principle:
The testing device is designed with universal connectivity to work with terminal blocks from both upper and lower sides. The testing device incorporates multiple connection interfaces and adaptable plug configurations that enable it to function equally well whether connected from above or below, thereby improving testing accessibility without significantly increasing device complexity.

Abstract
A testing arrangement is provided for testing the electrical circuits of an assembly of terminal blocks arranged in side-to-side relation, each of the terminal blocks including two mutually-insulated collinearly-arranged horizontal bus bar sections that are normally electrically connected by first and second pairs of leaf spring contacts arranged above and below the bus bar sections, respectively. During the testing operation, the testing device may be arranged either above or below the assembly, and an insulating test plug on the testing device is inserted either vertically downwardly from above, or upwardly from below, the terminal block, thereby to disengage one pair of contacts. A dummy plug is vertically inserted in the opposite direction to disengage the other pair of contacts. The remote ends of the bus bar sections are provided with clamping devices for connection with the bare ends of insulated conductors, respectively.
