Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a cover device for lead wires of a storage battery.

(Prior Art) Conventionally, a cover device for a lead wire of a storage battery as shown in FIG. 5 is known. That is, one of the combined containers consisting of the battery case a of the storage battery A and the lid b attached to its top surface.
At the end, as part of the battery case a, there are lead wires c,
A protective casing f is formed into one body, which has an accommodation space c, and is composed of both side walls d, d with open top and end surfaces, and a bottom wall e, and the lead wires c, c are inserted into the protective casing f. One end is connected to the terminals g and g of the storage battery, and its outer end is guided downward and led out to the outside through an outlet h opened at the outer end provided in the center of the bottom wall e, and the protective case f is The open top surface is covered with the end of the lid b, the cover i is fitted to the open end surface surrounded by the edge of the lid b and the protective case f, and the locking protrusion j provided on the cover i is A cover device for storage battery lead wires c, c is known, in which the cover i is fitted into a recess k provided on the inner surface of the protective housing wall.
is provided with a pair of arm plates m, m on both side edges of the mating substrate l, and at the tips of the arm plates m, m, locking linear protrusions j, j with a tapered cross section extending in the vertical direction.
A protrusion o having an L-shaped cross section is provided at the center of the lower edge of the fitting board l to be inserted and fitted into the outlet h at the center of the bottom wall e of the protective casing f, and the cover i is fitted into the opening end surface of the protective case f, and the locking protrusions j, j are inserted into the vertical fitting grooves k, k previously provided on the inner surfaces of both side walls d, d of the protective case f facing this. There is a type in which the cover device for the lead wire of the storage battery is constructed by fitting and engaging the protective case f and inserting the projection o at the center of the lower edge into the outlet h in the bottom wall of the protective case f.

(Problems to be solved by the invention) In the above-mentioned conventional type of cover device, the storage battery is hung and transported by holding the lead wires c and c,
Alternatively, when the lead wires c, c are pulled outward, the pulled lead wires c, c come into contact with the lower edge of the mating substrate l of the cover i, and a force is applied to the lower edge of the mating substrate l of the cover i. In other words, a force is applied in the direction of removing the mating substrate l, and the cover i is often unintentionally separated by the tensile force, and after the cover i is separated, the lead wire c , c are often seen to be disconnected from terminals g, g. The reason for this is that when the tensile force of the lead wires c and c is applied to the lower edge of the board l, the board l is deformed in a curved manner so as to warp diagonally upward, and the effect of this is to create a tapered shape at the tips of the arm plates m and m. This is thought to be because the protrusions n, n tend to come out of the grooves p, p.

(Means for Solving the Problem) The present invention eliminates the shortcomings of such conventional cover devices, and allows the cover to be easily removed from its mating protective housing even when a tensile force is applied to the lead wire. This provides a cover device for the lead wires of a storage battery that prevents them from coming off, and includes a storage space for the lead wires inside the outer end of the battery case of a combined container consisting of a storage battery case and a lid attached to the top surface of the case. A protective casing consisting of both side walls and a bottom wall with an open top and end faces.
A lead wire having one end connected to a terminal of the storage battery is led out through an opening provided in the bottom wall of the protective case, and the open top surface of the protective case is opened to the outside. The end of the lid is covered, the cover is fitted onto the open end surface surrounded by the downward peripheral edge of the lid and the protective housing, and the locking protrusion provided on the cover is fitted onto the inner surface of the protective housing wall. In a cover device for a lead wire of a storage battery that is fitted into a provided fitting and locking recess, the cover has at least one locking protrusion that projects downward from the lower edge of the fitting board;
At least one press-locking protrusion is provided on the upper edge of the protective housing, and the fitting-locking recess is provided on the inner surface of the bottom wall of the protective casing at a position corresponding to the locking protrusion. When fitting the cover to the open end surface of the protective case, fit the locking protrusion of the cover into the fitting locking recess on the bottom wall of the protective case, and press the locking protrusion on the upper edge of the cover. It is press-fitted to the edge of the periphery of the lid on the top surface of the protective casing.
