Abstract

An electrical connection terminal includes a metal part having a contact leg and a fastening leg which is connected to the contact leg by a web, the fastening leg having a spring receiving portion which has an inner side, an outer side, and an opening arranged in the spring receiving portion, and the contact leg having a contact portion which has an inner side and an outer side. A clamping spring can be mounted on the metal part, the clamping spring having a spring leg which has an end portion, a ridge connected to the spring leg on a side of the spring leg which faces away from the end portion, and a holding leg connected to the ridge. The ridge has a first recess and the holding leg has a second recess. The holding leg includes two side clips arranged in parallel with one another.

First claim

The invention claimed is:

1. An electrical connection terminal, comprising:
a metal part having a contact leg and a fastening leg which is connected to the contact leg by a web, the fastening leg having a spring receiving portion which has an inner side, an outer side, and an opening arranged in the spring receiving portion, the contact leg including a contact portion which has an inner side and an outer side; and
a clamping spring configured to be mounted on the metal part, the clamping spring having a spring leg which has an end portion, a ridge connected to the spring leg on a side of the spring leg which faces away from the end portion, and a holding leg connected to the ridge, the ridge having a first recess and the holding leg having a second recess, the holding leg including two side clips arranged in parallel with one another, a lower contact leg, and an upper transverse web, the upper transverse web separating the first recess in the ridge and the second recess in the holding leg from one another,
wherein a first tab is formed on the upper transverse web and the clamping spring is configured to be mounted on the metal part such that the first tab engages in the opening in the spring receiving portion from the inner side and the end portion of the spring leg rests against the inner side of the contact portion and so as to exert a spring force on the inner side of the contact portion.

2. The electrical connection terminal according to claim 1 , wherein the upper transverse web rests against the inner side of the spring receiving portion.

3. The electrical connection terminal according to claim 1 , wherein a length of the first tab corresponds to a material thickness of the fastening leg.

4. The electrical connection terminal according to claim 1 , wherein a region of the contact portion is angled downwards and the lower contact leg rests against the outer side of the angled contact portion.

5. The electrical connection terminal according to claim 1 , wherein an. edge region of the contact portion has two indentations, in each of which a side clip engages.

6. The electrical connection terminal according to claim 1 , wherein the ridge has two ribs which are arranged in parallel with one another and the spring receiving portion of the fastening leg has two indentations in an edge region of the fastening leg, and one rib engages in each indentation.

7. The electrical connection terminal according to claim 1 , wherein the upper transverse web has a second tab facing an opposite direction to the first tab.

8. The electrical connection terminal according to claim 1 , wherein the clamping spring and the metal part both include punched bent parts.
