More particularly, the present invention relates to a battery cover with bolt & nut locking mechanism of terminal post with cover protecting the terminal post and a terminal post capable of impede acidification thereof, mainly referring to the surface of the terminal post being formed with rounded step, so as to delay the acidification process and bolt nut locking for protecting the terminal post thereof.

Background of the invention and related prior Art

Battery cable terminal covers have been used in vehicles for many years to protect the battery cable terminal and battery post from water, dirt, salt, and other contaminants in the engine compartment. Battery cable terminal covers also protect the battery cable terminal and battery post from accidental electrical shorting.

Known covers are manufactured from materials such as rubber and plastic. Some covers protect only the top and sides of the battery cable terminal; i.e., they do not completely surround the terminal and are easily stretched and deformed, causing the cover to loosen and reduce its ability to protect the terminal. Thus, water, dirt and other contaminants can reach the terminal by traveling between the cover and the top of the battery. Also, the covers do not securely attach to the terminal and can become separated from the terminal due to vibration and inertial forces such as acceleration and deceleration. A loose or separated cover does not adequately protect the terminal from contaminants in the engine compartment and increases the possibility of electrical shorting.

Many known covers are attached to the battery post and held in place by the battery cable terminal.

Therefore, these covers are installed during installation of the battery into the vehicle. The covers cannot be attached to the battery cable terminal at some earlier time; e.g., during construction of the battery cable wiring harness, and, therefore, do not protect the terminal during shipment and installation.
Another prior art cover comprises hinged top and bottom sections which are connected by an integral pivot. The bottom section is adapted to receive and be secured to a split-ring cable terminal of the stamped, flanged type by urging the flanged terminal forward into a curved retention channel and then closing the top cover section over the bottom section. The cover also provides a large opening to allow the battery cable to enter the cover. The opening is substantially larger than the battery cable, leaving an area for dirt, water and other contaminants to enter the cover. Additionally, the cover does not have any mechanism to prevent over tightening of the split-ring terminal bolt, which can deform the terminal and reduce its ability to grasp the battery post.

The document US5503642 describes A hinged, shell-like protective cover is releasably mounted to a flanged, split-ring battery cable terminal. A method of assembling said cover to said battery cable terminal is also described. The cover surrounds the battery cable terminal, providing protection from dirt, water, salt, and other contaminants in the engine compartment of a vehicle. The cover includes a base having an aperture which is adapted to receive a battery post. The base is attached to a lid by an integrally molded hinge which allows the lid to pivot about the base between an open position and a closed position. A locking mechanism is provided to secure the lid to the base in the closed position. A pair of resilient locking arms are formed on the base and are adapted to receive a terminal bolt. A plurality of resilient tabs are formed on the base of the cover and located near the aperture in the base. The resilient tabs interact with a flange on the terminal to secure the terminal to the base.

According to the document KR20100006622, the invention states A battery cover combining structure of a sliding type and a portable terminal having the same are provided to easily separate and combine the battery cover from a main body and prevent the flow into a battery mounting unit. A battery cover(50) is slid in a portable terminal in order to cover up a battery mounting unit. A protrusion button(70) comprises a nut part in the rear side and protrudes the top end part to accommodation space formed around the battery mounting unit. An elastic body elastically supports the protrusion button. A fastening screw includes a screw head projected to the horizontal direction. The accommodation space comprises a protrusion.

The document FR2781764 describes the vehicle battery cover has a locking cavity with a lateral opening sufficient to allow the introduction of the nut fitting each end of the handle to be placed perpendicular to a passage hole. The hole and the cavity are connected by a central groove which allows free passage of the flexible cable. There are several anti-return protuberances which reduce the section of the cavity.
The other document JP2010015842 discloses a battery terminal and a terminal lower cover, capable of setting a current sensor in a space saved. ; Only if a lower part of a battery terminal body is covered with a terminal lower cover, mounting of the current sensor is automatically completed. Since the terminal lower cover happens to be a current-sensor-integrated terminal lower cover incorporating the current sensor, there is no need of mounting works of a current sensor itself. The battery terminal is so structured to cover a lower part of the battery terminal body with the use of the current-sensor-integrated terminal lower cover , that, once it is connected to a battery post, the current sensor is arranged to surround the battery post. When a cover-side locking of the current-sensor-integrated terminal lower cover and a terminal body side locking part of the battery terminal body are hooked to each other, a locking state is formed.

According to the document JP2006040797 an insulating cover for a battery preventing floating-up. The insulating cover for the battery terminal covers: the battery terminal having a ring part to be wound and attached to a battery post of the battery; and a plurality of connecting terminals connected to an electric wire connecting part 38 to be sequenced to the ring part of the battery terminal, and has a fitting locking part for locking to be fitted into the electric wire connecting part 38 or the connecting terminal in the cover interior. Furthermore, a floating-up stopping terminal locking which has elasticity and is hooked to the ring part to movement in the removing direction of the cover is integrally formed. Furthermore, an elastic retaining rib to be elastically contacted with the ring part is formed inside of the cover. A protective cover for a battery terminal contributing to high mounting capability of battery terminals having different sizes. This protective cover for the battery terminal is provided with a cover part covering a joint part of a battery post, and a housing part surrounding a connection part . The housing part has a cross- sectionally U-shaped form and is provided with a pair of side walls and. A clamp piece is formed on one-side sidewall, and plural lock teeth are longitudinally formed on the outer face side thereof in a serrated shape. A receiving part provided with a locking claw is projected on the other- side sidewall. When a suitable lock position matching to the connection part of the battery terminal is selected by selectively disengaging and engaging the locking claw from/with the lock teeth 43, the cover can surely be fastened by squeezing it according to the outside diameter of the connection part. Thereby, it can be held without looseness even to wires having various diameters, and generation of abnormal sound can be prevented which has been described in JP2002304983.
