ABSTRACT:
A wire lead strain relief mechanism includes a housing having a first wall and a second wall located in substantially parallel and spaced apart positions. The first wall carries a pair of spaced apart terminals and the second wall includes a generally flat surface with a pair of posts including a first post and a fifth post that are spaced apart a distance further than the terminals are spaced apart. The generally flat surface also has a set of three posts including a second post, a third post, and a fourth post all three positioned substantially in line with the first and fifth posts and substantially centered between the first and fifth posts. A wound coil is carried in the housing between the first and second walls and has a pair of terminal ends each engaging one of the terminals. A first wire lead has an insulating covering and is connected to the first terminal and extends from the first terminal around the first post and then in-between the second and the third posts so that the insulating covering is compressed and loads on the wire lead are attenuated at the first, second and third posts so that the first terminal is relieved from stresses. A second wire lead has an insulating covering and is connected to the second terminal and extends from the second terminal around the fifth post and then in-between the third and the fourth posts so that the insulating covering is compressed and loads on the wire lead are attenuated at the fifth, third and fourth posts so that the second terminal is relieved from stresses.
