Abstract

A cable clamp for a charging cable of an electric vehicle charging station. The cable clamp includes a first clamping piece and a second clamping piece that is complementary to the first clamping piece. The first clamping piece and the second clamping piece are adapted to be secured together and adapted to grip the charging cable of the electric vehicle charging station that passes through the first clamping piece and the second clamping piece. The shape of the first clamping piece and the second clamping piece includes a curved portion that forces the charging cable of the electric vehicle charging station to exit the electric vehicle charging station at a predetermined exit angle.

First claim

What is claimed is:

1 . A cable clamp for a charging cable of an electric vehicle charging station, comprising:
a first clamping piece; and a second clamping piece that is complementary to the first clamping piece; wherein the first clamping piece and the second clamping piece are adapted to be secured together and adapted to grip the charging cable of the electric vehicle charging station that passes through the first clamping piece and the second clamping piece; and wherein a shape of the first clamping piece and the second clamping piece includes a curved portion that forces the charging cable of the electric vehicle charging station to exit the electric vehicle charging station at a predetermined exit angle.

2 . The cable clamp of claim 1 , wherein the first clamping piece and the second clamping piece includes a plurality of internal ribs.

3 . The cable clamp of claim 1 , wherein the predetermined exit angle is at a minimum bend radius of the charging cable.

4 . The cable clamp of claim 1 , wherein a length of the first clamping piece and the second clamping piece is approximately six times a diameter of the charging cable.

5 . The cable clamp of claim 1 , wherein the predetermined exit angle is between 30 and 60 degrees.

6 . The cable clamp of claim 1 , wherein the first clamping piece and the second clamping piece are to be secured together with one or more fasteners and prevent the charging cable from being impinged.

7 . The cable clamp of claim 1 , wherein the charging cable is a liquid cooled cable.

8 . The cable clamp of claim 1 , wherein the first clamping piece and the second clamping piece are designed out of a rigid plastic material.

9 . The cable clamp of claim 1 , wherein the first clamping piece and the second clamping piece are to be secured to a housing of the electric vehicle charging station with or more fasteners.

10 . The cable clamp of claim 9 , wherein the cable clamp is to be located at an exit point of the housing of the electric vehicle charging station.

11 . An electric vehicle charging station, comprising:
a housing; a first clamping piece; and a second clamping piece that is complementary to the first clamping piece; wherein the first clamping piece and the second clamping piece are adapted to be secured together and adapted to grip a charging cable of the electric vehicle charging station that passes through the first clamping piece and the second clamping piece; and wherein a shape of the first clamping piece and the second clamping piece includes a curved portion that forces the charging cable of the electric vehicle charging station to exit the electric vehicle charging station at a predetermined exit angle.

12 . The electric vehicle charging station of claim 11 , wherein the first clamping piece and the second clamping piece includes a plurality of internal ribs.

13 . The electric vehicle charging station of claim 11 , wherein the predetermined exit angle is at a minimum bend radius of the charging cable.

14 . The electric vehicle charging station of claim 11 , wherein a length of the first clamping piece and the second clamping piece is approximately six times a diameter of the charging cable.

15 . The electric vehicle charging station of claim 11 , wherein the predetermined exit angle is between 30 and 60 degrees.

16 . The electric vehicle charging station of claim 11 , wherein the first clamping piece and the second clamping piece are to be secured together with one or more fasteners and prevent the charging cable from being impinged.

17 . The electric vehicle charging station of claim 11 , wherein the charging cable is a liquid cooled cable.

18 . The electric vehicle charging station of claim 11 , wherein the first clamping piece and the second clamping piece are designed out of a rigid plastic material.

19 . The electric vehicle charging station of claim 11 , wherein the first clamping piece and the second clamping piece are to be secured to the housing of the electric vehicle charging station with or more fasteners.

20 . The electric vehicle charging station of claim 19 , wherein the first clamping piece and the second clamping piece are to be secured to the housing at an exit point of the housing of the electric vehicle charging station.
