Embodiment Construction

[0015] The present invention will be further described below according to the accompanying drawings and in conjunction with examples of implementation.

[0016] The two-way anti-seepage lead bushing shown in the attached figure is a part to ensure the airtightness of the lead-acid battery. This part is implanted in the housing for positioning and installation of the terminals. The lead bushing is a flange-shaped component, with an axial taper sleeve in the center, and a radially protruding round edge connected to the taper sleeve, and integrated concentric circular shoulders with alternating concave and convex on the upper and lower end faces of the round edge. In this embodiment, due to the relatively small specifications of the supporting lead-acid battery, the upper and lower ends of the round edge are only provided with such figure 1 As shown in the two integrated concentric circular shoulders, a radially protruding circular shoulder is provided on the outer wall of the ro...

Abstract

The invention discloses a bi-directional anti-seepage lead bush which is a flange-shaped member. An axial taper sleeve is arranged in the center, a round edge extending radially is connected outside the taper sleeve, 2-5 concave and convex alternated integrated concentric circles are respectively formed on an upper end face and a lower end face of the round edge, and at least one radially extending integrated shoulder is arranged on an outer wall of the round edge, so that a structure integrating a double-end-face anti-seepage structure and an axial anti-seepage structure is formed. The bi-directional anti-seepage lead bush is structurally characterized in that a main anti-seepage structure is arranged on the end face, the position of the structure differs from the position of an axial anti-seepage structure in the prior art by 90 degrees, the most advantage of the position adjustment is that the anti-seepage structures are arranged on double faces, part of the axial anti-seepage structure is still remained, and the problem of acid seepage of a lead bush of a lead-acid battery shell is thoroughly solved under the actions of the double anti-seepage structures.

Description

technical field [0001] The invention relates to a lead bushing, in particular to a lead bushing pre-planted in a lead-acid storage battery case, in particular to a two-way anti-seepage lead bushing. The technical proposal belongs to the technical field of lead storage battery manufacturing. Background technique [0002] The shell of a lead-acid battery is a thin-walled container that stores dilute sulfuric acid, and is usually mass-produced by injection molding. In order to facilitate the positioning and installation of the terminals of the lead-acid battery, the lead bushing should be pre-planted when the casing is injection molded. Since the combination of the lead bush and the shell adopts an embedded structure, and the materials used for the two are different, the physical properties are completely different, especially the important index values ​​such as the strength and thermal expansion coefficient of the material are quite different. Under the same temperature con...
