Abstract

A system for mounting a refrigerant compressor housing ( 11 ) to a base plate ( 9 ) having threaded holes ( 10 ), the system comprising at least two screw pins ( 1 ) and one clip ( 2 ) for connecting the two screw pins, each screw pin ( 1 ) has a threaded portion ( 3 ), a middle portion ( 4 ) to be inserted into a respective opening ( 17 ) of the refrigerant compressor housing ( 11 ), a neck portion ( 5 ) having a smaller diameter than the middle portion ( 4 ) and a head portion ( 6 ) having a larger diameter than the neck portion ( 5 ). The elongate clip ( 2 ) has one slot ( 7, 8 ) respectively in each of its two end portions, the first slot ( 7 ) having a width equal to the diameter of the neck portion ( 5 ) of the screw pin ( 1 ) and being oriented in longitudinal direction of the clip ( 2 ), the second slot ( 8 ) narrowing to a width smaller than the diameter of the neck portion ( 5 ) of the screw pin ( 1 ) and then enlarging to a diameter equal to the diameter of the neck portion ( 5 ) and the second slot ( 8 ) being oriented normal to the longitudinal direction of the clip ( 2 ). This system has the advantages of convenient installation and stable fixation.

Claims (9)

1. A system for mounting a refrigerant compressor housing to a base plate having threaded holes, the system comprising at least two screw pins and one clip to connect the two screw pins, comprising: each screw pin, as seen in its longitudinal direction, has a threaded portion for screwing the screw pin into the threaded hole of the base plate, the threaded portion being followed by a middle portion to be inserted into a respective opening of the refrigerant compressor housing, the middle portion being followed by a neck portion having a smaller diameter than the middle portion, the neck portion being followed by a head portion, the head portion having a larger diameter than the neck portion, further comprising the clip has one slot in each of its two end portions, the first slot having a width equal to the diameter of the neck portion of the screw pin and being oriented in longitudinal direction of the clip, the second slot narrowing to a width smaller than the diameter of the neck portion of the screw pin and then enlarging to a diameter equal to the diameter of the neck portion and the second slot being oriented normal to the longitudinal direction of the clip.

2. The system according to claim 1 , wherein the enlarging portion of the second slot is again followed by a second narrowing portion which said narrowing and said second narrowing portions correspond to the outer dimensions of the neck portion of the screw pin in order to hold the neck portion within the enlarging portion and the second narrowing portion of the second slot.

3. The system according to claim 1 , wherein the clip is made of sheet metal.

4. The system according to claim 3 , wherein around the second slot the clip has at least one flap which is formed from the sheet metal of the clip by folding the sheet metal normal to the plane of the clip.

5. The system according to claim 4 , wherein a first flap is oriented parallel to the second slot.

6. The system according to claim 5 , wherein a second flap is oriented normal to the second slot and facing away from the entrance of the second slot.

7. The system according to claim 1 , wherein the at least two screw pins and one clip comprises four screw pins and two clips and that the first clip is the mirror image of the second clip.

8. The system according to claim 1 , wherein the head portion of the screw pin has indentations or lobes in order to allow the screw pin to be screwed in by hand or with a tool.

9. The system according to claim 1 , wherein the system further comprises the refrigerant compressor housing having four legs and the base plate having four said threaded holes, four said screw pins being screwed into the base plate, the middle portion of each said screw pin being in a respective opening of a said leg of the refrigerant compressor housing, the leg of the refrigerant compressor housing contacting the base plate, the at least one clip comprising two clips wherein the first clip having its first slot around the neck portion of a first screw pin and the second slot around the neck portion of a second screw pin, the second clip having its first slot around the neck portion of a third screw pin and the second slot around the neck portion of a fourth screw pin.
