Abstract
A pole cap for a battery pole of a battery has a sleeve-like contacting portion, which has an outer periphery widening conically in the direction of the battery pole and tapering conically in the direction of the battery pole. A terminal is formed as a double-walled terminal sleeve having an inner wall and an outer wall, both designed to be supported by a collar, where the walls form an annular gap for positively receiving the sleeve-like contacting portion of the pole cap and where the gap tapers in the direction of the collar.
Claims8
A pole cap of a battery pole of a battery of a vehicle, comprising:
- a fastening portion;
- and
- a contacting portion, wherein the contacting portion has an outer periphery which is continuously conically widening in a direction of the fastening portion along an entire length of the outer periphery from a distal top end of the contacting portion to a proximal end of the contacting portion at an annular stop surface of the pole cap, wherein the annular stop surface is disposed in a transition region between the fastening portion and the contacting portion, and has an inner periphery which is continuously conically narrowing in the direction of the fastening portion along an entire length of the inner periphery from the distal top end of the contacting portion to the proximal end of the contacting portion at the annular stop surface of the pole cap, and wherein the continuously conically widening outer periphery and the continuously conically narrowing inner periphery define a battery side contact surface therebetween such that the battery side contact surface is enlarged so that higher currents can be transmitted between the battery and an on-board electrical system of the vehicle.
