The present invention relates to engagement terminals of a DC power pack and a compressor.
A conventional DC power pack 90 is disclosed in
The present invention intends to provide engagement terminals on the power pack and the compressor so that the terminals are securely engaged with each other and the wasted heat is reduced.
The present invention relates to a power pack which includes a casing and a U-shaped frame is connected on a surface of the casing so as to be connected to two rails on a compressor. A first terminal and two first clamping plates extend from the surface of the casing and are located between two extensions of the U-shaped frame. A detecting pad is located on the surface of the casing and between the first terminal and the first clamping plates.
Each rail has a groove so that the two extensions of the U-shaped frame are engaged with the two grooves. The compressor includes a second terminal and two second clamping plates, wherein the first terminal is clamped between the two second clamping plates and the second terminal is clamped between the two first clamping plates.
The present invention will become more obvious from the following description when taken in connection with the accompanying drawings which show, for purposes of illustration only, a preferred embodiment in accordance with the present invention.
Referring to FIGS. 1 to 4, the power pack 1 of the present invention comprises a casing 10 in which a rechargeable battery (not shown) is received and a U-shaped frame 11 is connected on a surface of the casing 10. The U-shaped frame 11 includes a thin first extension 111 and a thick second extension 112. A first terminal 12 and two first clamping plates 13 are electrically connected to the battery and extend from the surface of the casing 10. The first terminal 12 and two first clamping plates 13 are located between the first and second extensions 111, 112 of the U-shaped frame 11. A detecting pad 14 is located on the surface of the casing 10 and between the first terminal 12 and the first clamping plates 13.
The compressor 2 of the present invention comprises an engaging device 20 comprising a first rail and a second rail. The first rail has a first groove 201 and the second rail has a second groove 202, wherein the two respective grooves 201 and 202 are sized to be correspondent to the thin first extension 111 and the thick second extension 112. The thin first extension 111 can be slidably engaged with the first groove 201, and the thick second extension 112 can be slidably engaged with the second groove 202. A second terminal 22 and two second clamping plates 21 extend from a surface of the compressor 2 and located between the two rails. The first terminal 12 is clamped between the two second clamping plates 21 and the second terminal 22 is clamped between the two first clamping plates 13.
The contact area between the first terminal 12 and the two second clamping plates 21, and between the second terminal 22 and the two first clamping plates 13 are large enough, and the first terminal 12 and the second terminal 22 are securely clamped so that no gap is defined between the clamping plates 13/21 and the two terminals 12/22. The detecting pad 14 detects the temperature of the power pack 1 and is connected to a warning light which is not shown so that any abnormal situation can be noticed by the user.
While we have shown and described the embodiment in accordance with the present invention, it should be clear to those skilled in the art that further embodiments may be made without departing from the scope of the present invention.
