Description

Battery pack pole with safety function

Technical Field

The utility model relates to the technical field, in particular to a battery pack pole with a safety function.

Background

A storage battery pole: refers to a member having one end directly connected to a bus bar and the other end connected to either an external conductor (also referred to as a terminal in this case) or one pole of an adjacent unit cell in a battery pack. Common storage batteries are: lead-acid batteries, cadmium-nickel batteries, iron-nickel batteries, zinc-silver batteries, zinc-nickel batteries, hydrogen-nickel batteries and lithium ion batteries.

The conventional battery pack pole is only a copper column with an upper thread and a lower thread for fixing, and the copper column only plays a role in transmitting current, and cannot block the current to protect external loads or the overload of the battery when the current is too large.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem of overcoming the defects of the prior art and provides a battery pack pole integrating plastic shell injection molding and glue sealing fixation, which has the function of fusing a fuse to cut off current to protect a battery pack or a load when the battery pack is overloaded and external short-circuit current is overlarge.

In order to solve the technical problems, the technical scheme provided by the utility model is as follows: a battery post with a safety function comprises the following components:

the ceramic shell is used for coating the outer side of the battery pack pole and is cylindrical;

the threaded sleeve is inserted into the upper part of the ceramic shell;

the lower pole is embedded in the bottom of the ceramic shell;

the fuse is placed inside the ceramic shell, and the lower part of the fuse abuts against the lower pole;

and the upper bolt is arranged on the upper part of the ceramic shell and is in threaded connection with the threaded sleeve, and the lower end of the upper bolt abuts against the upper end of the fuse and forms a circuit path.

Furthermore, the thread sleeve and the inner wall of the upper part of the ceramic shell are fixed through sealing glue.

Furthermore, the lower pole is made of a metal conductor.

Furthermore, the outer walls of the two sides of the lower pole are provided with fixing grooves, and limiting bulges matched with the fixing grooves are arranged in the ceramic shell.

Furthermore, the outer wall of the ceramic shell is provided with a groove gap for fixing in an injection molding piece through injection molding or sealing glue.

Compared with the prior art, the utility model has the advantages that: the fuse device is arranged in the pole, the fuse devices with different specifications can be removed for replacement, and when the battery pack is overloaded and the external short-circuit current is too large, the fuse can be fused to cut off the current so as to protect the battery pack or a load.

The utility model relates to an improvement of a conventional pole, which can fuse a fuse to cut off current to protect a battery pack or a load when the battery pack is overloaded and external short-circuit current is overlarge, so that the battery pack is safer.

As shown in the figure: 1. the device comprises an upper bolt, 2, a threaded sleeve, 3, a fuse, 4, a ceramic shell, 5 and a lower pole.

Detailed Description

In the description of the present invention, it is to be understood that the terms "center", "lateral", "upper", "lower", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate orientations or positional relationships based on those shown in the drawings, and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified. Furthermore, the term "comprises" and any variations thereof is intended to cover non-exclusive inclusions.

The present invention will be described in further detail with reference to the accompanying drawings.

In the specific implementation of the utility model, the upper bolt 1 is a bolt member of a national standard component. The thread is matched with the thread sleeve 2 through threads and screwed tightly. The fuse 3 is conducted with the thread bushing 2 and the lower pole 5 to pass current.

The thread bush 2 is in thread fit with the upper bolt 1 and is made of a common conductive material.

The fuse 3 is a current overload fusing device and is made of elastic materials. When in use, the upper part and the lower part are contacted with the upper bolt 1 and the lower pole 5, and the fuse protector can fuse when current is overloaded to play a role in protection.

Ceramic package 4 is that the insulator guarantees that the electric current is passed through by fuse 3 entirely, inlays integrative to thread bush 2 and lower utmost point post 5, plays the connection fixed action, and the middle recess breach that has moulded plastics in the 4 outsides of ceramic package can play the skid-proof effect of counter torsion in the injection molding or seal the glue.

The lower pole 5 is generally a metal conductor embedded in the ceramic shell 4, and a groove gap is embedded in the ceramic shell 4 to play a role in resisting torsion and preventing slipping.

When in use, the upper bolt 1 tightly screws the copper terminal of the external load on the threaded sleeve 2;

the screw thread of the battery pack module below is arranged on the lower pole 5, the thread bush 1, the fuse 3 and the lower pole 5 form a wire circuit when the device is used, and the fuse is fused to play a role in protection when the circuit is overloaded. The specification of the fuse 3 can be selected by the load power; the upper bolt 1 can be unscrewed and taken out for damage and replacement.

The present invention and its embodiments have been described above, and the description is not intended to be limiting, and the drawings are only one embodiment of the present invention, and the actual structure is not limited thereto. In summary, those skilled in the art should appreciate that they can readily use the disclosed conception and specific embodiments as a basis for designing or modifying other structures for carrying out the same purposes of the present invention without departing from the spirit and scope of the utility model as defined by the appended claims.
