Thermoformed plastic covered connectors
Abstract
Abstract CONNECTORS INCLUDING A PLASTIC COVERED METAL ELEMENT ARE MANUFACTURED BY THEREMOFORMING FLAT STOCK PLASTIC SHEET MATERIAL ONTO A MANDREL OF AN APPROPRIATE CONFIGURATION AND THEN CUTTING AWAY PORTIONS OF THE FORMED SHEET TO PROVIDE AN ARTICLE OF A DESIRED CONFIGURATION. THE MANDREL IS MADE TO CARRY THE METAL ELEMENT WHICH IS LOCKED INTO THE PLASTIC COVERING BY REASON OF A VACUUM DRAWM THROUGH HOLES IN THE MANDREL DURING FORMING. IN ONE EMBODIMENT A PREFORMED METAL ELEMENT IS ITSELF USED AS THE MANDREL WITH THE PLASTIC SHEET MATERIAL THEREMOFORMED AROUND A PORTION THEREOF AND THEN TRIMMED TO PROVIDE A FINAL ARTICLE CONFIGURATION. ASSEMBLIES OF PLASTIC COVERED ELEMENTS ARE PROVIDED BY LEAVING A PORTION OF THE THEREMOFORMED STRIP AS A WEB BETWEEN INDIVIDUAL ELEMENTS OR ALTERNATIVELY, THEREMOFORMING INSULATING SHEET MATERIAL ONTO STRIPS OF METAL ELEMENTS JOINED BY A WEB OF SHEET METAL STOCK FROM WHICH THE ELEMENTS WERE INITIALLY FORMED.
