Abstract

A protection circuit module has a substrate; a signal receiving connection terminal mounted on the substrate; a circuit portion mounted on the substrate, and electrically connected to signal receiving connection terminal; a first cover positioned over a first side of the substrate; and a second cover positioned over an opposite second side of the substrate, and into which the substrate is positioned.

Claims

1. A protection circuit module comprising:

a substrate;

a signal receiving connection terminal mounted on the substrate;

a circuit portion mounted on the substrate, and electrically connected to the signal receiving connection terminal;

a first cover positioned over a first surface of the substrate and including a circuit portion receiving slot extending through the first cover in a direction orthogonal to a plane defined by the substrate, the circuit portion positioned in the circuit portion receiving slot;

a second cover positioned over an opposite second surface of the substrate, and into which the substrate is positioned, the second cover including a connection terminal receiving housing having a cell lead guide slot extending through the second cover and the connection terminal receiving housing in the direction orthogonal to the plane defined by the substrate, the signal receiving connection terminal positioned in the connection terminal receiving housing; and

a support having a surface coupled with the second cover and a fastener receiving hole extending through the support, the support coupled with a battery module frame through the fastener receiving hole.
