Abstract

An electrical contactor a casing formed of an electrically insulating material and at least one connection terminal mounted in the casing configured to establish and maintain a contact between an electrical conductor inserted in the connection terminal and an electrical link bar mounted in the casing to ensure an electrical connection between the electrical link bar and the electrical conductor. The connection terminal having a contact spring configured so that the contact between the electrical conductor and the electrical link bar results from a force insertion of the electrical conductor in opposition to the action of the contact spring and is automatically maintained by the contact spring after insertion of the electrical conductor. The casing has a peripheral wall and a cover configured to be assembled together along a mounting direction substantially parallel to the direction in which the electrical conductor is inserted in the connection terminal.

First claim

What is claimed is:

1. An electrical contactor, comprising a casing formed of an electrically insulating material, at least one connection terminal mounted in the casing and intended to establish and maintain a contact between an electrical conductor inserted in the connection terminal and an electric link bar mounted in the casing in order to ensure an electrical connection between the electric link bar and the electrical conductor, wherein the connection terminal is of the push-in type and comprises a contact spring configured so that the contact between the electrical conductor and the electric link bar results from a force insertion of the electrical conductor in opposition to the action of the contact spring and is automatically maintained by the contact spring after insertion of the electrical conductor, wherein the casing comprises a peripheral wall and a cover that are assembled to one another in a mounting direction forming an angle with a direction in which the electrical conductor is inserted into the connection terminal, the angle being less than 30° and at least one insertion opening allowing insertion of the electrical conductor into the casing until the connection terminal is at least partially delimited by the cover and wherein the contact spring and the casing are configured so that the contact spring is mounted into the casing along a mounting direction substantially parallel to the direction in which the electrical conductor is inserted in the connection terminal.

2. The electrical contactor according to claim 1 , wherein the electrical contactor comprises blocking means secured to the cover configured to block the tilting of the contact spring relative to the casing during the insertion of the electrical conductor into the connection terminal and during the removal of the electrical conductor from the connection terminal.

3. The electrical contactor according to claim 2 , wherein the blocking means comprise at least one first abutment delimited by the cover and configured so that the contact spring comes automatically in abutment against the first abutment in order to block the tilting of the contact spring in a first way (S 1 ) during the insertion of the electrical conductor into the connection terminal.

4. The electrical contactor according to claim 3 , wherein the first abutment is arranged to block the contact spring along a longitudinal direction (X) and or along a transverse direction (Z) of at least one blade of the contact spring.

5. The electrical contactor according to claim 4 , wherein the contact spring comprises a protrusion extending laterally in the longitudinal direction (X) of the blade and in that the first abutment bears against said protrusion when the tilting of the contact spring in the first way (S 1 ) is blocked.

6. The electrical contactor according to claim 5 , wherein the contact spring comprises two blades linked to each other by a link portion and in that the first abutment is inserted transversely in a gap separating the two blades together along a lateral direction of the blades and bears longitudinally and/or transversely against the link portion.

7. The electrical contactor according to claim 2 , wherein the blocking means comprise a second abutment delimited by the cover and configured so that the contact spring comes automatically in abutment against the second abutment in order to block the tilting of the contact spring in a second way (S 2 ) during the removal of the electrical conductor from the connection terminal.

8. The electrical contactor according to claim 7 , wherein the second abutment is located facing at least one blade of the contact spring along the transverse direction (Y) of said blade and is arranged to block the contact spring along the transverse direction (Y).

9. The electrical contactor according to claim 1 , wherein the contact spring and the casing are configured so that the contact spring is mounted into the casing along a mounting direction substantially parallel to the direction in which the electrical conductor is inserted in the connection terminal.

10. The electrical contactor according to claim 1 , wherein the contact spring and the casing are configured so that the contact spring is mounted into the casing along a mounting direction substantially parallel to the direction in which the electrical conductor is inserted in the connection terminal.

11. The electrical contactor according to claim 1 , wherein the electrical contactor comprises blocking means secured to the cover configured to block the tilting of the contact spring relative to the casing during the insertion of the electrical conductor into the connection terminal and during the removal of the electrical conductor from the connection terminal.

12. The electrical contactor according to claim 1 , wherein the electrical contactor comprises blocking means secured to the cover configured to block the tilting of the contact spring relative to the casing during the insertion of the electrical conductor into the connection terminal and during the removal of the electrical conductor from the connection terminal.

13. The electrical contactor according to claim 1 , wherein the electrical contactor comprises blocking means secured to the cover configured to block the tilting of the contact spring relative to the casing during the insertion of the electrical conductor into the connection terminal and during the removal of the electrical conductor from the connection terminal.

14. The electrical contactor according to claim 13 , wherein the blocking means comprise at least one first abutment delimited by the cover and configured so that the contact spring comes automatically in abutment against the first abutment in order to block the tilting of the contact spring in a first way (S 1 ) during the insertion of the electrical conductor into the connection terminal.

15. The electrical contactor according to claim 14 , wherein the first abutment is arranged to block the contact spring along a longitudinal direction (X) and or along a transverse direction (Z) of at least one blade of the contact spring.

16. The electrical contactor according to claim 15 , wherein the contact spring comprises a protrusion extending laterally in the longitudinal direction (X) of the blade and in that the first abutment bears against said protrusion when the tilting of the contact spring in the first way (S 1 ) is blocked.
