Embodiment Construction

[0072] Figures 1a to 1j A wall penetration 1 with female plug contacts according to the invention is shown. The wall penetration device 1 has a two-part connector housing 102 comprising a front housing part 104 with a rear side insert 106, said front housing part having a front side receptacle Section, said insert is inserted into the front housing part 104 from the rear and is movable in the front housing part along the longitudinal axis 3 (axially) of the wall penetration device. The one-piece front housing part 104 has a front plug section 144 and a rear trunk sleeve 110 as well as a stop flange 107 arranged between the plug section 144 and the trunk sleeve 110 . The stem sleeve 110 is divided into an external thread adjoining the stop flange 107 and a sleeve section 112 adjoining the threaded section 108 . Thus, the stem sleeve mainly comprises a threaded section 108 and a smooth sleeve section 112 extending rearwardly from the threaded section.

Abstract

The invention relates to a wall feedthrough (1, 2), which is pluggable on one side, for connecting a voltage-conducting conductor (135) of a solar generator to a terminal housing, comprising: a two-part connector housing (102, 202) with a front housing part (104, 204) and an insert part (106) which can be moved together with an electric terminal element (114, 214) as one unit relative to the front housing part. The terminal element is pluggable on one side (118, 218) and has a spring clamp (120, 220) on the other side. The spring clamp is surrounded by a body casing (110, 210) of the front housing part in the closed state, and the clamping device (120, 220) is pulled out of the body casing (110, 210) in the open state so as to be openable and closable. For this purpose, the insert part has an exposed handle portion (150) for the user.

Description

technical field [0001] The invention relates to a one-sided pluggable wall feed-through for connecting a power supply cable of a solar generator to a connection housing, in particular a junction box of a solar system, which wall feed-through is intended in particular to be compatible with existing There are plug-in connector systems for solar installations that are compatible. Background technique [0002] Solar cell modules are usually connected in series in strings (so-called "strings") and multiple strings are connected in parallel depending on the specification of the solar generator. The wiring of the solar cell modules must satisfy a series of requirements for this purpose. On the one hand, string voltages are now typically up to 1000 volts and currents are in the ampere range. On the other hand, the connecting cables run at least partially outdoors and therefore have certain requirements for watertightness. [0003] The applicant has developed a trademark for this ...
