Abstract
An electronics device includes a housing having a through-hole disposed in a central portion of the housing. A printed circuit board is connected to the housing. The printed circuit board includes one or more electronic components disposed thereon. A plastic housing cover is connected to the housing and covers the printed circuit board. The housing cover includes a centrally-located post member integral to the housing. The post member extends through the through-hole of the housing and engages with the housing. The engagement between the housing and the housing cover prevents outward deflection of the housing cover.
Claims20
An electronics device, comprising:
- a housing, the housing including a through-hole disposed in a central portion of the housing;
- a printed circuit board connected to the housing, the printed circuit board including one or more electric or electronic components disposed thereon;
- and
- a housing cover connected to the housing and covering the printed circuit board, the housing cover including a centrally-located post member integral to the housing, the post member extending through the through-hole of the housing and engages with the housing, the engagement between the housing and the housing cover preventing outward deflection of the housing cover,
- wherein the housing cover further comprises a centrally-located protrusion which extends from the housing cover and surrounds the post member along a lengthwise segment thereof.

A method of assembling an electronics device, comprising:
- obtaining a housing having a through-hole disposed along a central portion thereof, a printed circuit board at least partly populated with electronic devices, and a plastic housing cover having a post member extending from an inner surface thereof;
- securing the printed circuit board to the housing;
- placing the housing cover over the printed circuit board so that the post member extends through the through-hole of the housing;
- securing the housing cover to the housing;
- and
- applying heat and pressure to a distal end portion of the post member so that the post member is formed over a portion of the housing which defines the through-hole and engages with the housing portion, the engagement preventing outward deflection of the housing cover.
