Abstract
A link for an electrical mounting rack terminal has two elongate, adjacent spring contacts which are held firmly against one another at a first end portion and can move resiliently at a second end portion. The link is latched to a housing of the electrical mounting rack terminal. A first embodiment of the link terminates flush with an outer contour of the housing. A second embodiment of the link has a grasping portion which protrudes beyond the outer contour of the housing. An electrical mounting rack terminal is also provided.
Claims20
A link for an electrical mounting rack terminal having a first busbar and a second busbar positioned at a distance from the first busbar, the first busbar being formed with a plug opening, the second busbar having a clamping web, comprising:
- two elongate, adjacent spring contact members, having respective first end portions, respective second end portions opposite from said respective first end portions, said spring contact members being held firmly against one another at said first end portions and being resiliently movable at said second end portions;
- said spring contact members having a central region between said first end portions and said second end portions, an upper contact zone in said central region of said spring contact members and a lower contact zone at said second end portions;
- each of said spring contact members having a first offset region provided at said upper contact zone and having a second offset region provided at said lower contact zone, said first and said second offset regions providing a first spacing between said spring contact members at said upper and lower contact zones and a second spacing between said spring contact members between said upper contact zone and said lower contact zone, the first spacing being larger than the second spacing, said first and second spacings being in a direction normal to a blank of metal from which said spring contact members have been formed;
- and
- said spring contact members having outside surfaces at said upper contact zone and inside surfaces at said lower contact zone, said spring contact members being configured to provide a pressure contact when inserted into a plug opening of a first busbar such that said outside surfaces at said upper contact zone form a contact to the first busbar, said spring contact members being configured to interact with a clamping web and being configured to be spread apart by the clamping web at said lower contact zone for forming a contact to a second bus bar at said inside surfaces.
