Electric connection receptable for a solar cell module
An electric receptacle and junction box for a solar cell module includes an enclosure base and an enclosure cover. The base has a first connector element for electrically contacting a strip conductor of a solar cell module, and a first conductor rail electrically connected to the first connector element. The cover has a second connector element for electrically contacting an output line, and a second conductor rail electrically connected to the second connector element. The first connector element and the first conductor rail are rigidly mechanically connected to the base. The second connector element and the second conductor rail are rigidly mechanically connected to the cover. Electrical contact is made between the first connector element and the first conductor rail and the second connector element and the second conductor rail in response to the enclosure cover and the enclosure base being joined together.
