Battery terminal connector with an uneven interior surface

A battery connector for an automotive vehicle battery comprising:

• a substantially cylindrical grip portion adapted to grip a conical battery terminal, said grip portion being provided with a plurality of ribs extending in substantially vertical direction, which grip portion has ends opposing each other and defining a space therebetween;
• a pair of first and second extensions extending respectively from said ends of said grip portion in substantially parallel relationship with respect to one another, one of said extensions being formed with a protruding portion which projects towards the other extension and which elastically prevents the extensions from approaching closer than a predetermined distance by acting as a fulcrum around which said extensions must bend in order for said gripping portion to be further tightened after said extensions approach said predetermined distance, said first extension being connected to a cable;
• and
• an auxiliary terminal provided at the free end of said second extension, said auxiliary terminal having a plurality of separate leg sections respectively adapted to be connected with auxiliary cables.

A battery connector for an automotive vehicle battery comprising:

• a substantially cylindrical grip portion adapted to elastically grip a conical battery terminal, said grip portion being provided with a plurality of inwardly protruding ribs extending vertically and in parallel to one another, said grip portion having end sections respectively separated in spaced relationship for permitting elastic engagement between said battery terminal and said grip portion;
• a pair of first and second extensions extending from said ends of said grip portion substantially parallel to each other;
• a means for biasing said first and second extensions toward each other to reduce the diameter of said grip portion for elastic engagement between said battery terminal and said grip portion;
• and
• a means for limiting the relative motion of said first and second extensions toward each other by acting as a fulcrum about which said extensions must bend in order to approach closer than a predetermined distance, said relative motion limiting means having elasticity for resisting the biasing force applied by said biasing means.

A battery connector for an automotive vehicle battery comprising:

• a substantially cylindrical grip portion adapted to elastically grip a conical battery terminal, said grip portion having inwardly protruded ribs extending in a vertical direction and arranged in parallel relationship with respect to each other, said grip portion having end sections separated from each other for permitting an elastic engagement between said grip portion and said battery terminal;
• a pair of first and second extensions respectively extending from said end portions of said grip portion in parallel relationship with respect to one another, said first extension being connected with a cable attached to vehicle devices;
• an auxiliary terminal provided at a free end of said second extension and having a plurality of separated connecting terminals respectively connectable with auxiliary cables;
• a first means for biasing said first and second extensions to each other to reduce the diameter of said grip portion for elastic engagement between said grip portion and said battery terminal;
• and
• a second means for limiting the relative motion of said first and second extensions toward each other, by acting as a fulcrum around which said extensions must bend in order to approach closer than a predetermined distance, said second means having elasticity for resisting the biasing force when the dimension between said first and second extensions becomes smaller than of said predetermined distance.
