An object of the invention is to provide a lid for storage battery comprising a terminal having a rectangular parallelepiped shape and a cavity portion, and a nut having a rectangular parallelepiped shape and being inserted into the cavity portion. The terminal has a first through-hole extending from an upper surface toward a lower surface of the terminal and a second through-hole extending from a front surface toward a rear plate portion of the terminal. The nut has a first screw hole extending from an upper surface toward a lower surface of the nut, and a second screw hole extending from a front surface toward a back surface of the nut, the first and second screw holes communicating with the first and second through-holes of the terminal, respectively. A direction in which the first screw hole extends does not intersect with a direction in which the second screw hole extends.

Lid for storage battery, injection molding method of the same lid, storage battery with the same lid, and terminal section for storage battery

An object of the invention is to provide a lid for storage battery, an injection molding method of the lid, a storage battery with the lid, and a terminal section for storage battery, which can save trouble of inserting a nut into a cavity portion of a terminal, and can prevent falling of the nut at the time of connection of an external leading wire. In a lid for storage battery in which a terminal section for storage batterymade up of a terminalhaving a cavity portion, a bushing, and a conductive portionjoining both is insert-molded in a lid made of synthetic resin, and a storage battery with the lid for storage battery, an anchor portionT is projected at a location excluding at least a central portion of a bottom portionF of the terminal, and a nut is inserted into the cavity portion of the terminal to be fixed. Moreover, in the terminal section for storage battery, the anchor portionT is projected at the location excluding at least the central portion of the bottom portionF of the terminal(e.g., the U-shaped anchor portionT is projected with a U-shaped joining portionG interposed).

A vehicular lead storage battery according to the present invention includes a battery container provided with at least one cell chamber; and a cover platefor covering an upper opening of the battery container. A guide pathfor discharging gases within a cell chamber to the outside is formed in the cover plate. The guide pathincludes a first guide portionB for horizontally guiding gases from the cell chamber; a second guide portionC connected to the first guide portionB to downwardly guide the gases from the first guide portionB; and a third guide portionA connected to the second guide portionC to horizontally guide the gases from the second guide portionC and discharge the gases from an exhaust ventK formed in the cover plateto the outside. A corner portionK is formed by the first guide portionB and the second guide portionC, and a corner portionK is formed by the second guide portionC and the third guide portionA. The guide pathis formed so that the angle &#x3b8; of a straight line L having internal contact with the two corner portionsK andK from a horizontal line is greater than the maximum angle of inclination at which the inclined angle of a vehicle is maximum during driving on a sloping ground.

Vehicular lead storage battery and vehicle equipped therewith

A storage battery includes a terminal portion for storage batteries having a plurality of bolt insertion holes bored in one or a plurality of directions, a nut insertion opening through which a nut is inserted, a hollow in communication with the bolt insertion holes and the nut insertion opening and the nut having at least one screw hole threaded in a direction coincident with at least one or the plurality of directions. A fixation portion is formed to fix the nut by deforming the terminal portion with the nut being inserted through the nut insertion opening into the hollow and the at least one screw hole of the nut being in communication respectively with the at least one of the plurality of bolt insertion holes.

Terminal portion for storage batteries, plastic encapsulated terminal for storage batteries, method for producing the same, storage battery provided with terminal portion, and automobile equipped with storage battery

There is provided a storage battery, including: a container having at least one cell chamber; a lid body () made of synthetic resin for covering a top opening of the container, the lid body having on a top surface a recessed portion that is recessed downward, the lid body having positive and negative electrode terminals disposed close to one side of the lid body and respectively at both end portions of said one side in a longitudinal direction, wherein the positive and negative electrode terminals () respectively have lower portions embedded in the lid body and upper portions projecting from the lid body; and an auxiliary lid () for closing the recessed portion. Conventional production of the storage battery has problems, for example, in that: when embedding a portion of a terminal to a lid body by insert molding, difference in shrinkage is caused between a surface in which a terminal body is embedded and a surface on which the terminal body is exposed, which results in difficulty in fitting the lid body to the container. The present invention is intended to solve this problem, for example, by providing the lid body of the storage battery with projections (T,T), each at a location at which the upper portion of each of the terminals projects, at a location proximate to the location at which the upper portion of each of the terminalsprojects, or at each of these locations.

Storage battery

An object of the invention is to provide a terminal section for storage battery that allows external leading wires to be simultaneously attached thereto at two or more locations, a nut for terminal of the terminal section for storage battery, a lid for storage battery with the terminal section for storage battery, and a storage battery. There is provided a terminal section for storage batterywhich is made up of a terminalhaving a cavity portion into which a nut is inserted, a bushing, and a conductive portionjoining both, wherein the terminalhas a rectangular parallelepiped shape, and through-holesKKof the terminalare formed at least at two locations of a rectangular upper surface plate portion and a rectangular front surface plate portion, and at positions where screw holes of the nut communicating with the through-holesKKof the terminaldo not intersect with each other, when the nut is inserted into the cavity portion of the terminal. Moreover, the nut for terminal to be inserted into the cavity portion of the terminalof the terminal section for storage battery, and a lid for storage battery with the terminal section for storage battery, and a storage battery are provided.

Terminal section for storage battery, nut for terminal of the same terminal section for storage battery, lid for storage battery with the same terminal section for storage battery, and storage battery

A lead-acid battery comprising a container having at least one cell chamber and a lid body for covering a top opening of the container. The lid body has on a top surface a recessed portion having therein an annular portion protruding upward and having, in an area of a bottom wall inside the protruding portion, an exhaust hole for exhausting gas from the cell chamber, wherein a guide passage for guiding gas from the exhaust hole to the outside is formed by joining the protruding portion with a joining portion provided on the lid body cover. An annular groove formed between the protruding portion and the vertical wall is covered with an outer periphery of the lid body coverand the guide passage is isolated from the groove.
