Conductor connection terminal, use thereof, and method for mounting a conductor connection terminal

A conductor connection terminal comprising:

• a contact insert that has a bus bar and a clamping spring;
• and
• a housing that has a first housing part and a second housing part and that at least partially encloses the contact insert,
• wherein the first housing part has a first housing wall with a receiving structure for receiving the contact insert and the second housing part has multiple additional housing walls for covering the contact insert received by the first housing part,
• wherein the receiving structure of the first housing part has frame walls that project essentially at right angles from the first housing wall and wherein, together with the first housing wall delimits a receiving space for the contact insert,
• wherein the first housing part and the second housing part each have a U-shaped cross section, wherein, in an assembled state of the housing, arms of the U-shaped cross section of the second housing part receive arms of the U-shaped cross section of the first housing part therebetween, such that the arms of the second housing part overlap with the arms of the first housing part, and wherein the arms of the first housing part receive the contact insert therebetween,
• wherein the arms of the first housing part are formed by the frame walls and the arms of the second housing part are formed by two of the additional housing walls, and
• wherein the frame walls overlap with the two of the additional housing walls, respectively, by a degree of overlap of more than 50%, such that regions of the housing have a double wall structure.
