Electrical connector assembly

1. An electrical junction box, comprising:

a junction box housing; and

an electrical bus bar element located inside the junction box housing,

wherein the junction box housing comprises openings configured to receive end portions of three electrical coaxial cables having braided shielding surrounding a central conductor,

wherein the electrical bus bar element comprises semicircular wings configured to be formed to at least partly surround ferrules provided at the end portions of electrical cables to establish electrical connection, thereby electrically interconnecting the braided shielding of the three electrical cables,

wherein the junction box housing is made of electrically conductive plastic and the electrical bus bar element is made of metal,

wherein the electrical bus bar element is designed to carry a current of at least 40 Ampere.

2. The electrical junction box according to claim 1 , wherein the junction box housing has an elongated shape, wherein a first opening of the openings is located at a first end of the junction box housing, and wherein a second opening of the openings is located on a second end of the junction box housing.

3. The electrical junction box according to claim 2 , wherein the connecting means are located adjacent to the first opening and to the second opening inside the junction box housing.

4. The electrical junction box according to claim 1 , wherein the electrical bus bar element comprises an elongated body and wherein the connecting means are arranged at ends of the elongated body.

5. The electrical junction box according to claim 4 , wherein the elongated body is Y-shaped and wherein the connecting means are arranged at the ends of the elongated body, whereby two connecting means are arranged on one end of the elongated body and whereby one connecting means is arranged at an opposite end of the elongated body.

6. The electrical junction box according to claim 1 , wherein the electrical bus bar element is made from a sheet metal.

7. The electrical junction box according to claim 1 , wherein the electrical bus bar element is made of a sheet metal that provides mechanical flexibility.
