Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a volume resistor with an interrupt electrode for connecting a volume resistor in series to a dry battery.

[0002]

[Prior art]

 Conventionally, an electric circuit made up of a dry battery and other electric components, which was not initially planned, was that when a dry battery and a volume resistor had to be connected in series, the dry battery and the volume resistance It had to be wired in series with lead wires, that is, the initial wiring had to be redone. However, the interrupt electrode (Fig. 4) of Japanese Patent Application No. 3-100552 interrupts the interrupt electrode in the dry battery, and the lead wire connected to the terminal is wired to the volume resistor (4), so that the initial wiring is redone. It was possible to connect the volume resistor (4) in series to the dry cell without doing so. However, the disadvantage of this is that the volume resistor is connected to the interrupt electrode only by a lead wire and is not held or fixed, so in order to prevent it from moving freely, the volume resistor should be Needed to be attached to an object. Another drawback is that the electrode B (2) conveniently contacts the cathode plate (21) of the battery B when the interrupt electrode is positioned in the state shown in FIG. 5 with respect to the battery, but as shown in FIG. However, when the interruption electrode cuts into the lower edge (22) of the battery case, the electrode B may not contact the cathode plate (21) of the battery B.

[Problems to be solved by the device]

 This invention is intended to eliminate the drawbacks of the interrupt electrode (Fig. 4) of Japanese Patent Application No. 3-100552. That is, holding the volume resistor on the interrupt electrode and ensuring that electrode B contacts the cathode plate of battery B.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the volume resistor with an interrupt electrode according to the present invention has the following structure.

It is joined to the electrode plate A (1) or the electrode plate B (2) which is not formed to electrically connect the terminal and the electrode plate, and the volume resistor (4) is connected to the electrode plate A (1). And the electrode plate B (2).

As a method for surely contacting the electrode plate B (2) with the cathode plate (21) of the battery B, in order to prevent the interrupting electrode from reaching the lower edge (22) of the battery case, the electrode plate A ( 1) Or, an interrupt limiting piece (9) was provided on the electrode plate B (2), and this interrupted the anode projection (20) of the battery A or the upper edge (23) of the battery case to limit the interrupt.

Another method for surely contacting the electrode plate B (2) with the cathode plate (21) of the battery B is to provide the electrode B with a cathode contact piece (24) made of a conductive material, By making the thickness of one piece larger than the gap between the electrode plate B (2) and the cathode plate (21) of the battery B, the contact with the cathode plate (21) of the battery B was ensured.
