Engagement terminals for DC power pack and copressor

Abstract

A power pack is engaged with a compressor by engaging a U-shaped frame with two grooves in two respective rails on the compressor. The power pack includes a first terminal and two first clamping plates, and the compressor includes a second terminal and two second clamping plates. The first terminal is clamped between the two second clamping plates and the second terminal is clamped between the two first clamping plates. The power pack includes a detecting pad for detecting the temperature of the power pack so that the user knows abnormal situation when using the power pack.

1 . A combination of a power pack and a compressor, the power pack comprising a casing and a U-shaped frame connected on a surface of the casing, a first terminal and two first clamping plates extending from the surface of the casing and located between two extensions of the U-shaped frame, a detecting pad located on the surface of the casing and between the first terminal and the first clamping plates, and 
 the compressor comprising two rails and each rail having a groove so that the two extensions of the U-shaped frame are engaged with the two grooves, a second terminal and two second clamping plates extending from a surface of the compressor and located between the two rails, the first terminal being clamped between the two second clamping plates and the second terminal being clamped between the two first clamping plates.    
   
   
       2 . The combination as claimed in  claim 1 , wherein the two extensions of the U-shaped frame includes a thin first extension and a thick second extension, the two respective grooves of the two rails are sized to be correspondent to the thin first extension and the thick second extension.
