Title:
ELECTROMAGNETIC RELAY AND ITS MANUFACTURE
Document Type and Number:
WIPO Patent Application WO/1995/008180
Kind Code:
A1
Abstract:
In this electromagnetic relay manufacturing method, a base block (20) is integrally molded with terminals (21, 22, 23 and 24) and connection projections (62 and 62) provided on a lead frame (60). Then, the terminals (21, 22, 23 and 24) from the frame (60) are cut off, and a permanent magnet (30) and armature (40) are assembled to the block (20). Finally, a case (50) is fitted down to the block, and the block (20) is removed from the projections. Therefore, the assembling accuracy and productivity of the electromagnetic relay can be improved because the electrical inspection and the aging can be performed while the base block (20) is connected to the lead frame (60).
