Lead wire engaging structure and electric apparatus

摘要

A lead wire engaging structure includes a first engaging portion and a second engaging portion. One end of the first engaging portion and one end of the second engaging portion are integrally provided at a first mounting portion integrally provided at a second casing wall portion. The first engaging portion forms a first gap between the first engaging portion and the second casing wall portion, and engages four lead wires in cooperation with the second casing wall portion. The first gap allows the four lead wires to pass therethrough. The second engaging portion forms a second gap between the second engaging portion and the first engaging portion. The second gap allows the four lead wires to pass therethrough. The other end portion of the first engaging portion and the other end portion of the second engaging portion are coupled to each other by a coupling portion.

主权项

1. A lead wire engaging structure configured to engage one or more lead wires at an electric apparatus casing including a first casing wall portion from which the one or more lead wires are led out and a second casing wall portion continuously formed with the first casing wall portion and extending in an intersecting direction intersecting a direction in which the first casing wall portion extends, the one or more lead wires having an insulating coating and being engaged at the second casing wall portion, the lead wire engaging structure comprising:
a first engaging portion fixed to the electric apparatus casing to form a first gap between the first engaging portion and the second casing wall portion and to engage the one or more lead wires in cooperation with the second casing wall portion, the first gap allowing the one or more lead wires to pass therethrough; and a second engaging portion fixed to the electric apparatus casing or the first engaging portion to form a second gap between the second engaging portion and the first engaging portion, the second gap allowing the one or more lead wires to pass therethrough, wherein the one or more lead wires are bent at an angled portion between the first casing wall portion and the second casing wall portion and then routed to pass through the first gap and then through the second gap to engage the one or more lead wires at the electric apparatus casing; the first casing wall portion includes a groove portion formed to open toward an outer wall surface of the first casing wall portion and an outer wall surface of the second casing wall portion and to receive a part of the one or more lead wires; the first engaging portion and the second engaging portion are entirely located in a space located in an extending direction in which the second casing wall portion extends with respect to an imaginary plane including the outer wall surface of the first casing wall portion, and are shaped such that a lead wire passage space allowing the one or more lead wires to pass therethrough is defined between the second engaging portion and the imaginary plane; the second casing wall portion includes an extending portion to which one end portion of the first engaging portion and one end portion of the second engaging portion are fixed; the other end portion of the first engaging portion and the other end portion of the second engaging portion are coupled to each other by a coupling portion; and the second engaging portion includes one slit formed at a center area of the second engaging portion and allowing one of the lead wires to pass therethrough while the insulating coating of the one lead wire is deformed by compression in the slit, the undeformed diameter of the one lead wire is larger than a size of the slit, wherein the second engaging portion is rigid.
