The present invention relates to a pattern fuse including a flame retardant coating layer and an opening, the pattern fuse being configured to prevent fire outbreak due to overcurrent generated when a circuit pattern is operated and to designate a breakage position, a flexible printed circuit board including the same, and a battery module including the same, wherein it is possible to prevent fire outbreak even when the pattern fuse is heated to a high temperature as the result of operation of the pattern fuse, and the pattern fuse is broken by fusing at a specific position thereof.

Pattern fuse including opening and battery module including the same

A pattern fuse includes a lower film layer, an adhesive layer stacked on the lower film layer, a circuit pattern made of a conductive material and provided on the adhesive layer, an upper film layer stacked on the adhesive layer and the circuit pattern and a coating layer configured to cover the opening of the upper film layer, wherein the coating layer includes a flame retardant material. The upper film layer has an opening formed therein that is configured to allow a part or the entirety of the circuit pattern to be exposed therethrough. A method of manufacturing the pattern fuse is also provided.

Pattern fuse and method of manufacturing the same

A connector assembly with rounded edges, in which an end of a female connector is formed in a round shape and a guide groove having an inner dimension receiving a wire is formed at an end portion to guide the wire to be curved to correspond to the round shape at a wire harness inlet end and guide the curved wire to be received in the guide groove, thereby guiding reduction of tension of the curved wire and prevention of interference with an external structure.
