Abstract
A method for manufacturing ultralow-resistance current sensors of size 0402 to 4518 of IEEE specifications includes the steps of: a raw metallic strip being pressed to roll over a first tension roller, a cutting tool over the first tension roller being fed to cut the raw metallic strip so as to form a deep groove thereof along the moving metallic strip, an insulating material being filled into and along the deep groove so as to form an lengthwise insulating portion of the metallic strip, and the metallic strip with the insulating portion being segmented into a plurality of ultralow-resistance current sensors.
Claims4
A method for manufacturing ultralow-resistance current sensors, comprising the steps of:
- (a) drawing a metallic strip having a first surface and an opposing second surface thereof;
- (b) using a cutting tool to cut into the first surface of the metallic strip by a predetermined depth;
- (c) drawing the metallic strip along a lengthwise direction so that a lengthwise groove is continually formed in middle portion of the first surface while the metallic strip is drawn;
- (d) filling an insulating material into the groove of the metallic strip;
- and
- (e) cutting into segments the metallic strip filled with the insulating material so as to produce a plurality of the ultralow-resistance current sensors.
