Abstract
The invention relates to a connection and junction box (1) for a photovoltaic solar module (24), which box in a mounting state, is put on the solar module (24) with open contact clamp(s) (22), and the contact clamps are actively closed for contacting the flexible flat conductor band(s) (28). Preferably, the actuating the contact clamp(s) (22) is automatically carried out by means of a device between two housing parts (2, 50), when putting on.
Claims14
A connection and junction box (1) for a photovoltaic solar module (24) having at least one flexible flat conductor band (28) protruding from the surface of the solar module, comprising
- a dielectric housing (3) to be put onto the solar module (24), having an insertion mouth (26) at the side (50a) of the housing, which side (50a) in mounted state faces the solar module (24), for inserting the flat conductor band (28) into the housing (3), wherein the housing (3) is formed at least two-piece, and the two housing parts (2, 50) are movable with respect to each other,
- a connection device (20) positioned in the housing (3), having a contact clamp (22) for electrically contacting the flexible flat conductor band (28),
- wherein the connection and junction box (1) defines a mounting state, and a contacting state,
- wherein the contact clamp (22) is open in the mounting state for being able to insert the flexible flat conductor band (28) into the open contact clamp (22),
- wherein the contact clamp (22) is closed in the contacting state for electrically contacting the flexible flat conductor band (28),
- wherein the connection and junction box (1) has an actuation arrangement (18) for closing the contact clamp (22), wherein the actuation arrangement (18) automatically closes the contact clamp (22) for contacting the flexible flat conductor band (28) in response to a movement of the two housing parts (2, 50) with respect to each other, after having put the connection and junction box (1) onto the solar module (24), and having inserted the flexible flat conductor band (28) into the housing (3).
A method for connecting a connection and junction box (1) to a photovoltaic solar module (24), comprising the steps of:
- providing a solar module (24) having at least one flexible flat conductor band (28) protruding from the surface (24a) of the solar module (24),
- providing a connection and junction box (1) comprising a housing (3) and a connection arrangement (20), which is positioned in the housing (3), with a contact clamp (22) for establishing a clamp contact with the flexible flat conductor band (28), and having an insertion mouth (26) at the lower side of the connection and junction box (1) as well as an actuation arrangement for actuating the contact clamp (22),
- putting the connection and junction box (1) on the solar module (24), wherein the connection and junction box (1) is put over the flexible flat conductor band (28) with the insertion mouth (26),
- inserting the flexible flat conductor band (28) into the catch area (31) of the open contact clamp (22), either when or after putting the connection and junction box (1) over the flexible flat conductor band (28), causing a movement of two housing parts (2, 50) with respect to each other, whereby the contact clamp (22) by is closed means of the actuation arrangement (18), and at this the flexible flat conductor band (28) is contacted.
