Electrical connecting device and method for its production and electrical line and solar modular arrangement with a connecting device of this type

1. An electrical connecting device, comprising:

an electrical conductor;

a housing having a receiving channel that receives the electrical conductor;

a contact element seated in the housing, the contact element having a piercing element extending into the receiving channel that electrically contacts the electrical conductor;

at least a portion of the housing and at least a portion of the electrical conductor in electrical contact with the piercing element being substantially surrounded by a common sheath made of a non-conductive material that forms a uniform bond with the housing and the electrical conductor; and

the electrical connecting device is T-shaped.

2. The electrical connecting device of claim 1 , wherein the sheath is an injection molded plastic material.

3. The electrical connecting device of claim 2 , wherein the housing is made from a polycarbonate and the sheath is made from a thermoplastic elastomer.

4. The electrical connecting device of claim 1 , further comprising clamping elements attached to the electrical conductor on opposite sides of where the electrical conductor is in electrical contact with the piercing element.

5. The electrical connecting device of claim 4 , wherein the clamps are surrounded by the sheath.

6. The electrical connecting device of claim 1 , wherein the receiving channel has a substantially U-shaped cross-section substantially matched to a diameter of the electrical conductor.

7. The electrical connecting device of claim 1 , wherein the contact element includes a connection member arranged opposite the piecing element that makes electrical contact with a counter-contact element.

8. The electrical connecting device of claim 7 , wherein the connection member of the contact element together with at least a portion of the housing is a plug connection for contacting the counter-contact element.

9. The electrical connecting device of claim 8 , wherein the plug connection has at least one polarization element for cooperating with a corresponding polarization element of the counter-contact element.

10. The electrical connecting device of claim 1 , wherein the housing includes a first portion and a second portion, the first portion having a smaller diameter than the second portion, the first portion containing the piercing member of the contact element, and the sheath substantially surrounds the first portion.

11. The electrical connecting device of claim 10 , wherein an outer surface of the sheath is substantially flush with an outer surface of the second portion.

12. The electrical connecting device of claim 1 , wherein the sheath is provided with kink protection members on opposite sides of where the electrical conductor is in electrical contact with the piercing element.

13. The electrical connecting device of claim 1 , wherein the electrical conductor is received in the receiving channel of more than one of the housings, is in electrical contact with the contact elements seated therein, and each of the housings is substantially surrounded by the common sheath.

14. The electrical connecting device of claim 13 , wherein the housings are spaced apart along the electrical conductor.

15. The electrical connecting device of claim 13 , wherein each of the housings is connected in series.

16. The electrical connecting device of claim 13 , wherein a plurality of solar modules are electrically connected to the electrical conductor through the contact elements.

17. The electrical connecting device of claim 16 , wherein the housings are spaced apart along the electrical conductor such that each of the housings are associated with one of the solar modules.
