SPRING CLAMP TERMINALS TERMINAL BLOCKSSPRING CLAMP TERMINALS TERMINAL BLOCKS

 

Spring clamps consist of a specially shaped stainless steel clamp, which functions as a spring for developing necessary contact pressure between current bar and conductor. The current bar is the current carrying part in the terminal block, and it is provided with serrations to grip the conductor. The spring clamp is brought under tension by inserting a screwdriver. This creates necessary opening in the clamp for inserting conductor. After the conductor is fully inserted the screwdriver is withdrawn. The clamp arm thereby presses the conductor firmly against the current bar, by spring action of the clamp.

 

 

DISTRIBUTION BLOCKS

TERMINAL BLOCKS ACCESSORIES

Selecting proper Accessories and using them correctly during assembly of Terminal Blocks is a very important function on the part of assembly-designers and assemblers of terminals blocks.

 

 These accessories are specially designed by Elmex to perform one or more of the following functions,  which ultimately help the user to derive optimum benefit from use of Elmex terminals.

 

END PLATE: For insulating end-of-stack terminals and for assembly of terminals of different sizes.

BARRIER PLATE: For increased values of clearances and creepages if required in specific applications / (standard designs already provide more than necessary values as per IEC60947-7-1.) and also for visible segregation of groups of terminals.

END CLAMP: For holding the stack of terminals blocks together, along the length of mounting rails.

PROTECTIVE COVER: For making entire stack of terminal block 'finger safe’, as preferred in some applications.

GROUP MARKER: For identification of individual terminals and for group-identification.

 

Naturally, use of accessories is first to be conceived by the assembly-designer of terminal blocks. Certain accessories such as End plates and End Clamps are mandatory. It is therefore as important to select proper accessories as to select terminal blocks, so that installation, maintenance and fault-tracing are all simplified at the design stage itself.


Necessary guidance for selection of accessories available for all the types of terminals blocks is given in following pages. The data on accessories for individual Terminals is provided with each terminal in the previous pages.

 

ACCESSORIES

 

END STOPPERS: Various types of end stoppers are available to suit different channels. End Stoppers can also be used as “spacers” to increase creepage distance between two terminals.
