Problems solved by technology

For example, heat can expand the material and create hot spots that warp through-holes and the entire bolt support
The deformation may cause the connection between the upper and lower shells to loosen

Embodiment Construction

[0025] A junction box assembly includes an upper casing, a lower casing, a connector assembly, and a bolt. The upper housing includes bolt supports. The bolt support is a cylindrical member having a top surface and a through hole. The lower case includes a bottom through hole. The connector assembly further includes a threaded hole. Bolts with threaded ends are provided in the through holes of the upper casing and the bottom through holes of the lower casing. The bolts are threadedly engaged with threaded holes of the connector assembly to secure the upper housing, lower housing and connector assembly together.

[0026] The top surface of the bolt support includes a plurality of holes. These holes provide tolerance for expansion due to heat generated by the power drill, thus preventing deformation of the outer dimensions of the bolt support in order to maintain contact between the upper housing, lower housing, connector assembly and bolts tight connection.

Abstract

The invention relates to a junction box assembly and an upper housing for use in the junction box assembly. The junction box assembly comprises an upper shell, a lower shell, a connector assembly and a bolt. The upper shell comprises a bolt supporting piece. The bolt support is a cylindrical member having a top surface and a through hole. And the lower shell comprises a bottom through hole. The connector assembly further includes a threaded bore. And a bolt with a threaded end is arranged in the through hole of the upper shell and the bottom through hole of the lower shell and is in threaded connection with the threaded hole of the connector assembly, so that the upper shell, the lower shell and the connector assembly are fixed together. The top surface of the bolt support includes a plurality of holes, each of which is closed at a bottom end.

Description

technical field [0001] The present disclosure relates to a junction box assembly and an upper housing for use in the junction box assembly. Background technique [0002] The junction box assembly includes an upper casing, a lower casing, a connector assembly, and a bolt. The upper housing includes bolt supports. The bolt support is a cylindrical member having a top surface and a through hole. The lower case includes a bottom through hole. The connector assembly further includes a threaded hole. Bolts with threaded ends are provided in both the through holes of the upper casing and the bottom through holes of the lower casing. The bolts are threadedly engaged with threaded holes of the connector assembly to secure the upper housing, lower housing and the connector assembly together. [0003] During manufacture, a power drill is used to thread bolts to the connector assembly. Electric drills can rotate up to a thousand times (1,000) per minute, which can generate enough ...
