Title:
DEVICE FOR MANUFACTURING COMB-SHAPED ELECTRODE
Document Type and Number:
Japanese Patent JPS5941271
Kind Code:
A
Abstract:
A single piece electrode comb or device includes two circuit boards having conductor paths and two separate rows of needle-like recording electrodes which are electrically connected to separate paths of the respective circuit board encapsulated in a single plastic resin body with the electrode rows extending to a recording edge formed in a rib along one edge of the body. To form the electrode comb, a device having two substantially similar rectangular cross-sectional shaped halves is assembled in one position to form a winding core on which a wire is wound with a plurality of turns, clamped and joined to the respective circuit boards which are mounted on faces of the two halves, subsequently the wires are separated along a parting plane and the two halves are disassembled with one being rotated 180 DEG relative to its previous position so that the faces with the recesses are adjacent each other to form a casting mold into which a plastic resin is injected to encapsulate the wires which after hardening of the plastic are trimmed back at least along the recording edge.
