Abstract

A conductor terminal with an insulating material housing and a spring-force terminal connection. The spring-force terminal connection has a contact body which is shaped out of a sheet element and has a base portion, lateral wall portions that protrude from the base portion and are mutually spaced, and solder connection contact tongues. The base portion together with the lateral wall portions forms a conductor receiving channel for receiving an electric conductor, and leaf spring tongues protrude from the lateral wall portions so as to face one another, each leaf spring tongue has a clamping edge for clamping an electric conductor received in the conductor receiving channel. The insulating material housing has a conductor insertion opening which leads to the conductor receiving channel on the front face.

First claim

What is claimed is:

1. A conductor terminal comprising:
an insulating material housing;
a spring-force terminal connection having a contact body shaped from a sheet element with a base portion, lateral wall portions protruding from the base portion and spaced apart from one another, and solder connection contact tongues,
a conductor receiving channel formed by the base portion with the lateral wall portions, the conductor receiving channel adapted to receive an electric conductor;
at least one leaf spring tongue that has a clamping edge for clamping the electric conductor that is received in the conductor receiving channel, the at least one leaf spring tongue protruding from the lateral wall portions; and
a conductor insertion opening formed on a front side of the insulating material housing that leads towards the conductor receiving channel,
wherein the solder connection contact tongues are bent out of a plane of the base portion, and open up a solder connection plane that is arranged offset to the base portion and form an indented region of the base portion, and
wherein a closure cover is provided to latch into the indented region.

2. The conductor terminal according to claim 1 , wherein the closure cover has latching tabs that are adapted to latch into latching openings in the contact body.

3. The conductor terminal according to claim 1 , wherein the closure cover has latching openings or latching edges that are adapted to latch with latching tabs of the contact body.

4. The conductor terminal according to claim 1 , wherein the closure cover has fingers protruding substantially perpendicularly from a cover plate of the closure cover, wherein a pair of such fingers are arranged spaced apart and opposite each other and are adapted for immersion into the indented region for abutment adjacent against a connecting web of the contact body that leads from the base portion to a solder connection contact tongue.

5. The conductor terminal according to claim 4 , wherein the fingers each have a latching contour, wherein the latching contours are each formed to latch with a latching tab of the contact body.

6. The conductor terminal according to claim 4 , wherein the fingers each have a latching tab which is formed to latch into a latching opening of a respective adjacent connecting web of the contact body.

7. The conductor terminal according to claim 4 , wherein, between two juxtaposed fingers of the closure cover, cover tongues of the cover plate protrude on the plane of the cover plate, wherein the cover tongues remain free via slots in the portions of the cover plate that transition into the fingers.

8. The conductor terminal according to claim 1 , wherein the cover portion of the insulating material housing, which is situated opposite the base portion, is completely closed on a side of the spring-force terminal connection facing upwards away from the base portion in a region adjacent to the lateral wall portions and the leaf spring tongues of the contact body, wherein actuating tabs protrude from the leaf spring tongues facing away from the base portion, wherein the insulating material housing has on a back side an actuating opening leading towards the actuating tabs, which is situated opposite the conductor insertion opening, and wherein the actuating opening is delimited by the cover portion of the insulating material housing to form a guide channel.

9. The conductor terminal according to claim 8 , wherein the guide channel of the actuating opening is formed by the cover portion by spaced-apart lateral portions of the inner wall of the insulating material housing and by a cover portion and the opposing socket portions.

10. The conductor terminal according to claim 9 , wherein, in forming a conductor receiving pocket, the socket portion is spaced apart from the base portion of the spring-force terminal connection.

11. The conductor terminal according to claim 8 , wherein the guide channel ends immediately upstream of the actuating tabs.

12. The conductor terminal according to claim 8 , wherein the actuating opening extends from the back to the front side through the insulating material housing and opens out at the front side, adjacent to the conductor insertion opening.

13. The conductor terminal according to claim 12 , wherein an actuating element is slidably accommodated in the actuating opening, wherein the actuating element has a protruding actuating portion that is designed for the application of force on the actuating tabs to open the clamping point formed by the clamping edges.

14. The conductor terminal according to claim 13 , wherein the actuating element has a head portion that is accessible from the back side of the insulating material housing for applying the force, and a signal portion that protrudes from the front side of the insulating material housing when the spring-force terminal connection is in an open state.

15. An assembly comprising:
a conductor terminal according to claim 8 ; and
an actuating tool having a holding portion and an actuating finger for insertion into the actuating opening and for pushing apart the actuating tabs to open a clamping point.

16. The assembly according to claim 15 , wherein the holding portion and the actuating finger are at an angle to each other.

17. The assembly according to claim 15 , wherein, on the holding portion, at least two juxtaposed and spaced-apart actuating fingers are provided for insertion into a respective associated actuating opening of at least two actuating openings of the insulating material housing of the conductor terminal.

18. The conductor terminal according to claim 1 , wherein an indentation, which transitions into an actuating opening, is arranged on the cover portion in a back region of the insulating material housing, which is located opposite the conductor insertion opening.

19. The conductor terminal according to claim 1 , wherein the insulating material housing has a plurality of juxtaposed conductor insertion openings, and wherein the conductor terminal has a plurality of spring-force terminal connections adjacently received in the insulating material housing and are associated with a respective conductor insertion opening.
