UN CONJUNTO ELECTRICO TAL COMO POR EJEMPLO UNA BOCINA.

摘要

An electrical horn has a hollow body fitted with a diaphragm secured to an armature. A self-supporting coil is disposed with clearance in a recess in the body. The coil has no central former but is provided with upper and lower electrically insulating flanges. The flange has laterally projecting support portions engaging the body. The support portion has an integral upstanding post fitted with an electrically conducting sleeve. Mounted in stacked relationship on the support portion and around the post and sleeve are an eyelet and an electrical connector. The post and sleeve are deformed to produce a head which holds the eyelet and electrical connector in engagement without the need to use a rivet extending through the support portion and the body. This reduces the risk of entry of water into the body in service. The lack of a central former for the coil improves air circulation therearound.
