Motor protector attachment system

Attachment apparatus for mounting a motor protector in a housing for electrical connection with an electric motor disposed within the housing, the motor protector having a generally oval shape in plan view with a cup shaped housing received on a generally flat header, the motor protector having three terminals, at least two of the terminals being pins projecting from within the motor protector housing through the header and being spaced from one another by a distance d comprising:

• a bracket having a flat bottom wall formed with an upstanding back wall and at least one side wall connected to the back wall, the back wall having a distal free end, a generally L-shaped slot having first and second slot portions extending from the distal free end of the back wall, the first slot portion extending toward the bottom wall to the second slot portion that in turn extends toward the said one side wall, to an end, a second slot extending from the distal free end of the back wall toward the bottom wall, the second slot being cut away to form a pin receiving seat at a location spaced from the bottom wall the same distance that the second slot portion of the first slot is spaced from the bottom wall, the pin seat being spaced from the said end of the first slot at least a distance d,
• a stop surface extending upwardly from the bottom wall and being spaced from the back wall a distance selected to engage the motor protector when received in the bracket,
• a clip retaining slot formed in the side wall and clip retaining features formed on the bottom wall, and
• a metallic spring clip having a bottom wall and a side wall, the clip formed with a selected width between first and second side ends to accommodate the bottom wall of the said bracket, the side wall of the clip disposed at one side end formed with a tab adapted for receipt in the clip receiving slot of the bracket, the second side end of the clip formed with attachment features engageable with the clip retaining features on the bottom wall of the bracket, the side wall being capable of being biased to allow the bracket to be attached to the clip, the clip adapted to be fixedly mounted to the casing of a motor.

Attachment apparatus for mounting a motor protector in a housing for electrical connection with an electric motor enclosed within the housing, the motor protector having a generally cup shaped housing received on a generally flat header, the motor protector having three terminals, at least two of the terminals being pins projecting from within the motor protector housing through the header and being spaced from one another:

• a bracket having a flat bottom wall formed with an upstanding back wall and at least one side wall connected to the back wall, the back wall having a distal free end, a generally L-shaped slot having first and second slot portions extending from the distal free end of the back wall, the first slot portion extending toward the bottom wall to the second slot portion that in turn extends toward the said one side wall to an end, a second slot extending from the distal free end of the back wall toward the bottom wall, the second slot being cut away to form a pin receiving seat at a location spaced from the bottom wall the same distance that the second slot portion of the first slot is spaced from the bottom wall, and
• a stop surface extending upwardly from the bottom wall and being spaced from the back wall a distance selected to engage the motor protector when received in the bracket so that the motor protector housing is directly exposed to the ambient to provide suitable thermal coupling to the ambient within the housing.
