ABSTRACT:
FIELD OF THE INVENTION
This invention relates generally to an electrical power connector system and more particularly to an electrical power connector system that is adapted for use with automotive electrical storage batteries.
BACKGROUND OF THE INVENTION
A ring terminal type battery system has long been a standard in the industry. However, the ring terminal with bolt-on action has relatively high warranty costs due primarily to cross threading and stripping bolts. Assembly on the factory floor is also different. Also, with the standard ring terminal, the user is able to jump start a vehicle which can be undesirable in some instances. A direct connect system is needed which replaces the ring terminal type battery, lends itself to normal processing methods, can be made at a lower cost, and permits more convenient mating of the terminal parts with one another.
SUMMARY OF THE INVENTION
The connection system of this invention overcomes the shortcomings of previous systems. The system of this invention has no bolt-on action and does not permit a jump start. Preferably the system includes a female connector and a male connector. The female connector has a female terminal inside a female housing. A contact member is held by the female terminal. The male connector includes a male terminal inside a male housing. The male and female housings are releasably connected together with the male terminal engaging the contact member. A connection position assurance device (CPA) is provided to assure the connection between the male and female housings.
Preferably the male terminal is in the form of a single blade, and the female terminal is in the form of a generally U-shaped channel defining a recess. The contact member is also generally U-shaped and is releasably received in the recess of the channel. The single blade male terminal extends into a second recess formed by the U-shaped contact member.
One object of this invention is to provide a direct connect power battery system having the foregoing features and capabilities.
Another object is to provide a direct connect power battery system which is composed of a relatively few simple parts, is rugged and durable in use, and is capable of being easily manufactured and assembled.
