Abstract: A junction box assembly includes first and second structures, such as upper and lower cases. T-shaped aligning protrusions extend beyond an edge of a sidewall of the second structure and mate with a receiving member contained in the first structure. When the first structure is being aligned with the second structure, chamfers on the T-shaped aligning protrusion may be provided to help start the alignment process before the first and second structures are joined together. This allows for faster and easier assembly of the junction box and helps to reduce the mating forces between the first and second structures.

Abstract: A junction block assembly includes a junction block holding at least two first connectors, and at least two second connectors that mate with the first connectors. To reduce the force required to assemble the connectors, first and second cam levers are rotatably mounted to the junction block. The first and second cam levers each engage one of the second connectors and pull the engaged second connector into connection with a mating one of the first connectors. An arm of the second cam lever travels past an arm of the first cam lever during rotation.
