Abstract
A fastening clamp for fixing a terminal block in a wall opening in a housing wall, having a clamp housing and at least one clamping element. The fastening clamp allows the terminal block to be mounted in and removed from a wall opening in a housing wall with a small width in that the clamping element has a resilient snap arm, having a foot region fastened to the clamp housing and a free end forming a clamping face, the snap arm extending along the side face of the clamp housing so that the clamping face acts on an edge of the wall opening when the fastening clamp is in the mounted state. A blocking element is displaceably mounted on the clamp housing for movement between a first position in which the resilient snap arm can be deflected, and a second position in which the blocking element cannot be deflected.

Fastening clamp for securing a modular terminal block that has multiple modular terminals in a wall opening of a housing wall, comprising a terminal housing and at least one clamping element, wherein the clamping element has a clamp surface,
- wherein the clamping element is a sprung ratchet arm which is fastened at a foot area to the terminal housing, and the clamp surface is formed on a free end,
- wherein a ratchet arm extends along a lateral surface of the terminal housing, in such a way that the clamp surface in an assembled state of the fastening clamp acts against one edge of the wall opening, and
- wherein a locking element is arranged to move on the terminal housing, and can be brought from a first position into a second position, wherein in the first position of the locking element, the sprung ratchet arm can be deflected in a direction of the lateral surface of the terminal housing, while the locking element in its second position is arranged partially between the free end of the sprung ratchet arm and the lateral surface, in such a way that the sprung ratchet arm cannot be deflected in the direction of the lateral surface of the terminal housing.
Component that comprises two fastening clamps and a modular terminal block that has multiple modular terminals that are arranged adjacent to one another, wherein the modular terminals are arranged between the fastening clamps and in each case have a terminal housing with at least two conductor connection elements that are arranged therein, wherein each of the fastening clamps comprises:
- a terminal housing and at least one clamping element, wherein the clamping element has a clamp surface,
- wherein the clamping element is a sprung ratchet arm which is fastened at a foot area to the terminal housing, and the clamp surface is formed on a free end,
- wherein a ratchet arm extends along a lateral surface of the terminal housing, in such a way that the clamp surface in an assembled state of the fastening clamp acts against one edge of the wall opening, and
- wherein a locking element is arranged to move on the terminal housing, and can be brought from a first position into a second position, wherein in the first position of the locking element, the sprung ratchet arm can be deflected in a direction of the lateral surface of the terminal housing, while the locking element in its second position is arranged partially between the free end of the sprung ratchet arm and the lateral surface, in such a way that the sprung ratchet arm cannot be deflected in the direction of the lateral surface of the terminal housing.
