Description

Button batteries used in small devices are sold in a wide variety, but even if the nominal voltage is the same, the size and shape differ depending on the capacity. Battery cannot be used.

Regarding the holder to which the button battery is mounted, a structure that takes out the potential by pressing a metal spring against the positive and negative electrodes of the battery is generally used, so only a button battery that matches the holder can be used, and the capacity is the same even if the voltage is the same. Cannot be selected arbitrarily, and contact failure due to deformation of the spring material is likely to occur.

Problems that the device tries to solve

Capable of attaching various sizes and shapes of button batteries, the capacity can be freely selected as long as the nominal voltage is the same, and the reverse of the potential to the circuit to be connected even when the button battery poles are reversed. Provided is a small button battery holder capable of preventing application.

Means for solving the problem

A first magnet having a conductive treatment on the surface and a second magnet are arranged, the negative electrode surface of the button battery is adsorbed by the first magnet, the positive electrode side surface is adsorbed by the second magnet, and each magnet Extract potential from the conductive part

Effect of device

A small button that can be used regardless of the size and shape of the button battery if the nominal voltage is the same, and prevents reverse application of potential to the connected circuit if the battery is installed in the wrong direction. A battery holder is realized.

As shown in FIG. 2, the button battery is composed of a positive electrode surface 1, a positive electrode side surface 2, and a negative electrode surface 3, and the negative surface 3 is insulated from the positive electrode side surface and protrudes by L on the inner side. Even if it makes it, a magnet does not touch a negative electrode surface. In general, the pole cap of the button battery is made of a magnetic material such as iron, and is therefore attracted to the magnet. FIG. 1 shows an embodiment of a button battery holder according to the present invention. The positive electrode side surface 2 is adsorbed by the positive electrode magnet 4 and the negative electrode surface 3 is adsorbed and held by the negative electrode magnet 5. Since the surface of the magnet is electroplated with a metal such as Ni, it has conductivity, so that the positive potential of the battery is taken out by the positive lead 7 through the positive magnet 4 and the negative potential is taken out by the negative lead 8 through the negative magnet 5. It is. Reference numeral 6 denotes a base such as a non-conductive resin on which a magnet is disposed. Since the button battery is attracted in the horizontal and horizontal directions by the positive magnet 4 and the negative magnet 5, the size and shape of the battery are hardly restricted. Also very low.

When the button battery is mounted upside down, the positive electrode side surface 2 contacts the positive electrode magnet 4 and the positive electrode surface 1 contacts the negative electrode magnet 5, so that the positive electrode potential appears on the lead wire. The reverse application of the potential is prevented. FIG. 3 shows the mounting situation when the battery size is small, and it can be seen that even if the size and shape of the battery are changed, the magnet is used for adsorption so that the adaptability is high. In this way, since the button battery of various sizes and shapes can be attached to and removed from this holder, the capacity can be freely selected if the nominal voltage is the same, and it can be connected even if the button battery is reversely installed. It is a small button battery holder that can prevent the reverse application of potential to the circuit.

The magnet is a cylindrical neodymium magnet with Φ3 × 2mm and Ni-plated on the surface, the base is made of PP resin, and the plane size of the base is 20 × 23mm for CR2032 battery, but the button battery is lightweight Therefore, the magnet may be extremely small. For example, in CR20 type, there are various types such as 2012, 2016, 2025, 2032, etc., the diameter is Φ20, the height is different even at the same 3V, and the capacity is greatly different from 55 mAh to 210 mAh. Therefore, if the battery holder is free of battery size, the capacity can be selected, and the options for the user are greatly expanded. FIG. 4 shows a structure in which a positive electrode conductive material 9 and a negative electrode conductive material 10 are sandwiched between a magnet and a battery when a magnet whose surface is not subjected to a conductive treatment is used. Take out at 7,8. Any conductive material may be used as long as it has conductivity, such as iron, copper, phosphor bronze, and stainless steel. The magnet is not limited to neodymium, but may be ferrite, and the base may be a non-conductive material. The various dimensions can be variously modified without departing from the spirit of the present invention.
