Electric wall feedthrough for solar installations

摘要

A wall feedthrough is provided, which is pluggable on one side, for connecting a voltage-carrying conductor of a solar generator to a combiner box housing. A two-part connector housing having a front housing part and an insert part which can be moved together with an electric terminal element as one unit relative to the front housing part, wherein the terminal element is pluggable on one side and has a spring-force clamp on the other side, and wherein in the closed state, the spring-force clamp is surrounded by a body sleeve of the front housing part, and in the open state the clamping device is pulled out of the body sleeve so as to be openable and closable, and wherein, for this purpose, the insert part has an exposed handle portion for the user.

1. A wall feedthrough pluggable on one side, for connecting a voltage-carrying conductor of a solar generator to a connection box housing comprising:
an insulating connector housing with a stop and a mounting portion; an electric terminal element extending axially within the connector housing; and a mounting element; wherein the connector housing is formed at least in two parts comprising i) a front housing part having a front plug-in portion in the form of a housing plug pin or a housing plug socket, a body sleeve for being inserted into an opening of a wall of the connection box housing, and the stop, wherein the connector housing can be fixed in the opening, with the stop on the one side and the mounting element on the other side; and ii) an insert part inserted into the front housing part at a rear axial end thereof opposite to the plug-in portion; wherein the electric terminal element comprises a front plug-in terminal and a rear clamping device for a conductor end for electrically connecting the conductor end with the plug-in terminal when the conductor end is clamped in the clamping device; wherein the electric terminal element is fixed within the insert part and the insert part is guided slideably along its longitudinal extension within the body sleeve, so that the insert part together with the electric terminal element fixed therein can be reversibly inserted and retracted between a closed state of the connector housing when inserted into the body sleeve and a retracted open state of the connector housing, so that in the closed state, the clamping device is surrounded by the body sleeve and the plug-in terminal is arranged in the plug-in portion, so as to be able to be mated with a complementary plug-in terminal of a mating connector, and so that in the open state, the plug-in terminal is at least partially pulled out of the plug-in portion and the clamping device is pulled out of the body sleeve so as to be openable and closable.
