Description

Technical Field

[0001] The utility model belongs to the technical field of lead-acid batteries, in particular to a lead-acid battery bridge assembly. Background Art

[0002] Lead-acid battery is a storage battery whose electrodes are mainly made of lead and its oxides, and whose electrolyte is sulfuric acid solution. When the lead-acid battery is in the discharge state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; when it is in the charging state, the main components of the positive and negative electrodes are both lead sulfate.

[0003] Since the lead-acid battery is composed of single cells connected in series, the method adopted for connecting the single cells in series inside the battery is to weld the single cells together using cross-bridge butt welding. However, the cross-bridge structure of the existing lead-acid battery will inevitably cause upper and lower misalignment or cold welding between the busbars when in use, which affects the yield rate of battery production and its performance. Utility Model Content

[0012] Furthermore, the limiting mechanism includes a limiting slide groove and a clamping groove. The limiting slide groove is arranged on the outer side of the span body one and the span body two, and the protrusion on the inner wall of the connecting component is slidably clamped on the inner side of the limiting slide groove. The clamping groove is arranged at one end of the span body one and the span body two, and the cross-section of the clamping groove is a triangular structure.

[0013] Furthermore, a stepped groove is provided at one end of the connecting component, and the connecting piece is embedded in the stepped groove, the locking groove is symmetrically provided at the upper end of the stepped groove, and the cross section of the locking groove is a "T"-shaped structure.

[0014] Furthermore, a welding groove is provided on the outer side of the connecting piece, and welding through holes are evenly provided on the inner wall of the welding groove.

[0015] Furthermore, the welding locking mechanism includes a connecting slide groove and a limiting plate. The connecting slide groove is arranged on the left and right sides of the connecting piece, and the upper end of the connecting slide groove is a diamond structure. The limiting plate is slidably engaged in the inside of the connecting slide groove.

[0016] The utility model has the following beneficial effects:

[0017] The utility model can limit the position of the connection component by setting a limit slide groove and cooperating with the clamping groove, and can avoid the connection component from being offset.
