Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a measurement terminal used when measuring, for example, a battery voltage or internal resistance.
[0002]
[Prior art]
For example, a large number of batteries used as emergency power supplies are connected in series and parallel and used in parallel with a power supply. In principle, this battery cannot be disconnected when the power supply is operating.
On the other hand, a battery connected to a power source needs to be inspected whether or not it can be used as an emergency power source by measuring voltage and internal resistance periodically.
[0003]
Therefore, conventionally, measurement terminals are fixed to individual batteries, lead wires are connected to the measurement terminals, and wiring work is performed in advance when the batteries are installed to prepare for subsequent measurement work.
[0004]
The conventional measurement terminal has a structure in which it is fixed to the battery with bolts and nuts, etc., and the measurement terminal and the lead wire are pressure-bonded and cannot be separated from each other.
[0005]
[Problems to be solved by the invention]
However, as described above, it is troublesome and expensive to perform wiring work for battery inspection in advance when installing the battery.
[0006]
Therefore, it is conceivable to perform measurement work by connecting lead wires to the battery when necessary, without performing wiring work for battery inspection in advance when installing the battery.

The pair of side surface portions 12 is not limited to a shape in which the lower side is bent into a “<” shape. For example, the lower side of the pair of side surface portions 12 is bent into a “J” shape, The lower side of the side surface portion 12 may be folded into a “<” shape and the lower side of the other side surface portion 12 may be folded into a “J” shape.
[0021]
The cut-and-raised protrusion 13 is formed by cutting out a part of the side surface portion 12. In the embodiment, two sides of the triangle are cut out on the basis of the position bent in the “<” shape, and the inside of the pair of side surfaces 12 is arranged such that the top portion 13A of the cut-out triangle faces the top surface portion 11 side. It is located. The shape of the cut-and-raised protrusion 13 is not limited to a shape obtained by cutting out two sides of a triangle, and may be formed by cutting out, for example, three sides of a quadrangle, preferably a trapezoid. Also, the number of the cut and raised protrusions 13 is selected as appropriate.
As shown in FIG. 2, the measurement terminal having the above-described configuration is used with a strip-shaped conductor 20 sandwiched between a pair of side surface portions 12. That is, the strip-shaped conductor 20 is connected to the terminals of the battery to connect between the batteries, and the strip-shaped conductor 20 is sandwiched between the pair of side surface portions 12.

The belt-like cut-and-raised protrusion 13-2 is bent into a substantially L-shape and is positioned inside the pair of side surface portions 12.
[0024]
As shown in FIG. 4, the measurement terminal having the above configuration is used by sandwiching the strip-shaped conductor 20 between the pair of side surface portions 12. However, when the strip-shaped conductor 20 is sandwiched between the pair of side surface portions 12, 13A is engaged with the strip-shaped conductor 20, and the cut-and-raised projection piece 13 mainly plays a role of preventing the measurement terminal from coming out of the strip-shaped conductor, while the strip-shaped projection-and-projection piece 13-2 is The band-shaped conductor 20 is brought into surface contact, and the cut-and-raised protrusion 13-2 mainly plays a role of electrically connecting the measurement terminal to the band-shaped conductor. Thus, by cutting and raising and forming the projecting piece 13-2, there is an effect that the electrical connection between the measuring terminal and the strip conductor can be reliably performed.
