Abstract
Abstract A small electric motor whose small case has a through hole through which a motor terminal can be taken out is disclosed. A first slot which is right-angled longitudinally to the through hole and extends to the side face of the small motor case is provided in the end of the small motor case where an opening of the through hole is provided, and a second slot extended from the first slot is provided in the side face of the small motor case. Furthermore, a first kick is provided in the bottom of the first slot and a second kick is in the side face of the second slot.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
251 words
A small electric motor construction for facilitating an electrical connection to a power supply terminal (13), comprising: a case including an end wall (7) having a terminal through hole (6) therein; a motor supported in said case having a resilient bendable conductive motor terminal (5) extending out of said case through said through hole; said case having a side wall (9) adjacent the hole (6) which meets said end wall at a corner and extends perpendicularly to said end wall; both said end wall (7) and said side wall (9) having an interconnecting recess area (8, 10) extending from a location on an opposite side of said terminal (5) of said end wall and around said corner into said side wall; said conductive terminal being made of material which is readily bendable and being selectively bendable away from said side wall to resiliently engage with a supply terminal substantially aligned with said motor terminal and disposed at right angles to said end wall, and also being selectively bendable at substantially right angles into the recess (8) of said end wall (7) to engage with a supply terminal which is disposed parallel to said end wall, and also being selectively bendable in substantially U-shape into the recess (10) of said side wall (9) to engage with a power supply terminal laterally offset from said motor terminal; said recess (10) of said side wall being of sufficient length to receive said U-shape motor terminal; said motor terminal comprising an electrically conductive metal plate.
Claim 2
Dependent Claim
251 words
A small electric motor construction for facilitating an electrical connection to a power supply terminal (13), comprising: a case including an end wall (7) having a terminal through hole (6) therein; a motor supported in said case having a resilient bendable conductive motor terminal (5) extending out of said case through said through hole; said case having a side wall (9) adjacent the hole (6) which meets said end wall at a corner and extends perpendicularly to said end wall; both said end wall (7) and said side wall (9) having an interconnecting recess area (8, 10) extending from a location on an opposite side of said terminal (5) of said end wall and around said corner into said side wall; said conductive terminal being made of material which is readily bendable and being selectively bendable away from said side wall to resiliently engage with a supply terminal substantially aligned with said motor terminal and disposed at right angles to said end wall, and also being selectively bendable at substantially right angles into the recess (8) of said end wall (7) to engage with a supply terminal which is disposed parallel to said end wall, and also being selectively bendable in substantially U-shape into the recess (10) of said side wall (9) to engage with a power supply terminal laterally offset from said motor terminal; said recess (10) of said side wall being of sufficient length to receive said U-shape motor terminal; said motor terminal comprising an electrically conductive metal plate.
Claim 3
Dependent Claim
44 words
A small electric motor according to claim 1, including a protuberance formed in said side wall overlying the recess (10) therein and on each end of the recess (10), sized to engage over said motor terminal when it is bent into said recess (10).
Claim 4
Dependent Claim
45 words
A small electric motor according to claim 1, including a protuberance (14) rising in the recess (8) of said end wall (7) on a side of said motor terminal adjacent said side wall (9), said protuberance forming a kick over which said terminal is bendable.
