Abstract

The utility model provides a novel storage-battery wiring clamp, and relates to the technical field of the manufacture of lead-acid storage batteries. The clamp comprises two clamping arms which are disposed oppositely. The two clamping arms are connected through a rotating shaft which is sleeved by a torsional spring. The two clamping arms are respectively an upper clamping arm and a lower clamping arm. One end of the upper clamping arm is an upper clamping handle, and the other end of the upper clamping arm is an upper clamping head. One end, corresponding to the upper clamping handle, of the lower clamping arm is a lower clamping handle. One end, corresponding to the upper clamping head, of the lower clamping arm is a lower clamping head. The upper clamping handle is provided with a wire connecting point. The butt joint surface of the upper and lower clamping heads is a plane clamping surface which is provided with a butt-joint clamping groove, wherein the butt-joint clamping groove is semi-circular. According to the utility model, toothlets of a clamping surface of a conventional wiring clamp are all removed, and the clamping surface is changed into a plane clamping surface which is provided with a semi-circular clamping groove, thereby effectively increasing the contact area of the plane clamping surface with a stainless steel screw rod, reducing the heating caused by that the contact area is small, preventing a wiring terminal of a storage battery from being loosened, avoiding liquid leakage, guaranteeing that the wiring clamp is not liable to falloff in use, and improving the safety of an application process.

Description

A new battery terminal

technical field

The utility model relates to the technical field of power lead-acid storage battery manufacturing, in particular to the field of production and charging of lead-acid storage batteries for electric vehicles, in particular to a novel storage battery connection clip.

Background technique

At present, lead-acid batteries are widely used in electric vehicles. According to the characteristics of electric vehicles, it is required to use the whole set of batteries. If a certain battery fails, it will form a vicious circle and cause the failure of the entire set of batteries. battery packs. There is a very important link in the production process of the battery-acid charging. After adding acid to the battery, multiple batteries are combined in series to form a circuit for charging, and the batteries are connected through terminal clips.

Existing manufacturers only require acid resistance for the junction clips, and have not studied the structure and shape of the junction clips, and have always used ordinary structures for use. In order to prevent the terminals from being oxidized and rusted during the charging process of the battery, the terminals are lengthened and led out through stainless steel screws, and the terminal clips are connected with the stainless steel screws. According to the actual production verification, when the ordinary structure of the terminal clamp clamps the stainless steel screw, the contact area is relatively small, and when a large current passes through, it will generate heat, which will be transmitted to the terminal, which will cause the terminal to loosen, and finally lead to battery wiring. There is acid leakage at the terminals; during the production process, when workers walk back and forth, they will knock off the clamps, which directly affects the product quality and poses a safety hazard.

Utility model content

The purpose of this utility model is to provide a new type of storage battery terminal clip to solve the above technical problems. The terminal clamp can not only effectively increase the contact area with the stainless steel screw, reduce the heat generated due to the small contact area, avoid the occurrence of loose terminal terminals and liquid leakage of the battery, but also ensure that the terminal clamp is not easy to fall off during use.

The technical problem to be solved by the utility model adopts the following technical solutions to realize:

A new type of battery connection clamp, including two clamp arms set opposite to each other. The two clamp arms are connected by a rotating shaft, and a torsion spring is covered on the rotating shaft. It is characterized in that: the two clamp arms are respectively an upper clamp arm and a lower clamp arm. One end of the upper clamping arm is the upper clamping handle, the other end is the upper clamping head, the end of the lower clamping arm corresponding to the upper clamping handle is the lower clamping handle, and the end corresponding to the upper clamping head is the lower clamping head. There is a wire connection point at the upper clamp handle, the mating surface of the upper chuck and the lower chuck is a flat clamping surface, and the flat clamping surface of the upper chuck and the lower chuck is provided with a mating clamping groove , the clamping groove is semicircular.

As a further improvement, a pair of clamping grooves, or at least two pairs of clamping grooves with unequal diameters are provided on the flat clamping surface to meet the clamping requirements for different diameters of stainless steel screws.

As a further improvement, the upper clamping handle is covered with an insulating sleeve, and an anti-slip structure is provided on the insulating sleeve.

As a further improvement, the anti-skid structure is bumps or embossments.

As a further improvement, the upper clamping handle and the lower clamping handle are covered with insulating sleeves, and the insulating sleeves are provided with anti-slip structures.

As a further improvement, the insulating sheath is a plastic sheath.

As a further improvement, the wire connection point provided at the upper clamping handle is connected to the wire by welding, which can ensure that the wire is welded firmly.

The beneficial effects of the utility model are:

The utility model provides a new type of battery connection clip, which removes all the small teeth on the clip surface of the existing connection clip and changes it into a flat clip surface, and sets a semicircular clip groove on the flat clip surface, and the diameter of the clip groove is according to the stainless steel The diameter of the screw rod is designed so that the terminal clip fits well with the stainless steel screw rod when it is in the closed state; and it can effectively increase the contact area with the stainless steel screw rod, reduce heat due to the small contact area, and avoid loosening and leakage of the battery terminals It can also ensure that the terminal clip is not easy to fall off during use, and improve the safety of the use process.
