Terminal

1. A terminal for a circuit board, comprising:

at least one clamping contact situated in a housing, the clamping contact including a contact element and a clamping spring, wherein the clamping spring is operable via an operating element, and wherein a projection is situated on the operating element, the projection striking a stopping edge of the housing in the position of the operating element causing the clamping spring to open, wherein the operating element has a bevel which is in flush contact with a beveled surface of the housing in the position of the operating element causing the clamping spring to be clamped.

2. The terminal as recited in claim 1 , further comprising a counter-projection situated on the side of the operating element opposite the projection, the counter-projection striking an interior stopping edge of the housing in the position of the operating element causing the clamping spring to be clamped.

3. The terminal as recited in claim 1 , further comprising a plug-in contact situated on the contact element for attachment to a multi-pin connector.

4. The terminal as recited in claim 1 , wherein the operating element is a one-piece injection molded part made of plastic.

5. A terminal, comprising:

a housing;

a clamping element disposed in said housing;

an operating element that penetrates said housing and engages said clamping element, wherein said operating element includes a first projection that strikes a first stopping edge of the housing and stops said operating element in a first position that moves said clamping element into an open position, and a second projection disposed on said operating element, wherein said second projection strikes a second stopping edge of said housing when said operating element is moved outward from said housing and stops said operating element in a second position that allows said clamping element to move into a clamped position; and

a contact element disposed in said housing, wherein said contact element includes a first portion and a second portion, and wherein said first portion of said contact element contacts a first part of said clamping element.

6. The terminal as recited in claim 5 , wherein movement of said operating element causes a second part of said clamping element to move between said open position and said clamped position and wherein said second part of said clamping element clamps a conductor inserted into said housing against said second portion of said contact element when said clamping element is in said clamped position.

7. The terminal as recited in claim 5 , wherein the operating element includes a bevel which contacts a beveled surface of the housing in a second position of the operating element that allows said clamping element to move into a clamped position.

8. The terminal as recited in claim 5 , further comprising:

a connector that protrudes into said housing and contacts a conductor inserted into said housing.

9. The terminal as recited in claim 5 , wherein the operating element is a one-piece injection molded part made of plastic.
