Disclosed is a water-proof connector assembly which comprises a first connecting device, a second connecting device and a fastener. The first connecting device includes a first casing, a male conductive terminal, a water-resisting member and a first screwing member. The first casing, being provided successively a first section, a second section, a third section and a fourth section, has a first inner hole. The second connecting device includes a second casing, a female conductive terminal which allows the male conductive terminal to insert for conducting electricity, a second water-proof sleeve and a second screwing member. The second casing, being provided successively a fifth section, a sixth section and a seventh section, has a second inner hole. The fastener is mounted around and movable on a first outer surface of the first section and the second section of the first casing between a predetermined first position and a predetermined second position.

Water-proof connector assembly

The connector system has female-male lead-in ducts (1a,1b) which are provided with plastic torso housing units (10a,10b). The torso housing units are provided for forming annular stop surface (13a) at mounting pins (12a) with respect to the connector housing (11a). The female plug contact (33a) arranged opposing to male plug contact (33b) is provided on both sides of plug metal contact elements (30). The contact portions (31a,31b) of contact elements are connected with respective rear crimping portions (32a,32b) by welding, soldering or direct crimping process.

Electrical plug connector system for photovoltaic systems, has plug metal contact elements whose contact portions are connected with respective rear crimping portions by welding, soldering or direct crimping process

The inverter has housing (22) having wall opening (20) in outer wall (22a). The wall opening has extension larger than single lead-in duct (14) of lead-in duct component (10) with cover plate (12). The lead-in duct component with lead-in ducts and cover plate is formed as prefabricated unit and is fixable in housing. The cover plate is mounted in housing to sealingly close wall opening, or to form as a portion of outer wall for transmitting electric power from strand cables to electronic components (24) through lead-in ducts if lead-in duct component is secured at housing.

Inverter for photovoltaic solar array has lead-in duct component with lead-in ducts and cover plate, which is formed as prefabricated unit and is fixable in housing

The electrical plug connector, for mounting in a wall, has an installation section (1) at one end with a ratchet (3) and a fastener (4) and a connection section (2) for another connection at the other end. The plug is held in place by the ratchet sprung open at one side of the wall and the fastener at the other side. A seal (6) is between the fastener and the wall, with a compression stop (7) at the fastener for the seal.
