Embodiment Construction

[0097] figure 1 An open perspective view of an electrical junction box 01 for a photovoltaic module 02 (schematic only) with a box receptacle 03 and a box cover 04 in the figure. The figure includes a view from above looking into the cartridge receptacle 03 and a view from below into the cartridge cover 04 . In this embodiment of the invention, there are n=4 different assembly positions, and both the box cover 04 and the box socket 03 are square 20 . Thus, the box socket 03 contains four positive contacts 05 with contact means 06 for the positive pole 07 and four negative contacts 08 with contact means 06 for the negative pole 10 of the photovoltaic module 02 Contact device 09. The four positive contacts 05 are electrically connected in series with each other and are connected to the contact means 09 by means of a wire 11 with an electrically insulating sheath. The four negative contacts 08 are also electrically connected in series with each other and are connected to the ...

Abstract

Known junction boxes set the alignment of the external connection cables of the photovoltaic module, which are rigidly connected with a box lid. In the junction box (01) according to the invention, the box lid (04) can be placed on the box receptacle (03) in two or more different fitting positions, wherein a positive contact (05) and a negative contact (08) in the box receptacle (03) are provided for each fitting position. A positive mating contact (23) and a negative mating contact (24) are arranged in the box lid (04). According to the invention, the contacts (05, 08) and mating contacts (23, 24) are situated in such a way that, in each fitting position of the box lid (04) on the box receptacle (03), the positive mating contact (23) can be electrically contacted with one of the positive contacts (05), and the negative mating contact (24) can be electrically contacted with one of the negative contacts (08). According to the invention, the final fitting position of the box lid (04) on the box receptacle (03) is selected based on a prescribed alignment of the connection cables (30, 32) relative to the photovoltaic module (02). The invention makes it possible to preassemble junction boxes (01) and adjust them to each photovoltaic module (02) by selecting the fitting position, and hence alignment of the connection cables (30, 32).

Description

technical field [0001] The invention relates to an electrical junction box for a photovoltaic module with a box socket having at least one first and one second positive contact for contacting the positive pole of said photovoltaic module and a box cover , the box socket also has at least one first and one second negative contact for contacting the negative pole of the photovoltaic module, and the box cover has at least one positive matching contact and at least one negative matching contact, wherein, when After the box cover is placed on the box socket in at least one mounting position, the mating contacts are in contact with contacts of the same polarity, at this time, a positive connection line is connected to the at least one positive mating contact, A negative connection line is connected to the at least one negative matching contact, and the positive and negative connection lines are fixed to the box cover in a fixed outgoing direction. [0002] Photovoltaic modules, als...
