Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery holder and, more particularly, to a button-type battery holder used in various electronic and electric appliances.

[0002]

2. Description of the Related Art Portable communication devices, timers, table clocks,
Button-type batteries are used as a power source in household appliances such as toys and remote controls, electronic appliances such as calculators, electronic notebooks, and digital cameras, and electronic appliances and electrical appliances that are used daily, such as industrial measuring instruments. I have.

[0003] In general, commercial power is used as a power source in fu- micone game machines, notebook personal computers, notebook type word processors, and the like. When a non-energized state occurs due to a power failure or the like, a button-type battery is used as a power source of a memory backup circuit to protect a memory (memory circuit).

Conventionally, a button-type battery used as a power source or a button-type battery used as a backup power source in the above-described various devices has conventionally been configured such that a positive electrode and a negative electrode of a battery are respectively fixed to predetermined portions of a wiring board by soldering. Was. However, when a button-type battery (hereinafter simply referred to as a battery) is fixed to a wiring board by soldering, it is difficult to replace a worn-out battery personally, and a request is made to a dealer or a manufacturer for replacement of the battery. In such a case, there is a problem that it takes time to replace the device, so that the device cannot be used during that time, and that replacement requires a cost.

Therefore, in recent years, a holder that can accommodate a battery without directly soldering the battery to a wiring board has been used. FIGS. 13 (a) and 13 (b) show an example of a conventional battery holder. One side surface in a case b made of an insulating material having a space capable of accommodating the battery a is connected to a positive electrode of the battery a. A possible plus terminal member c is provided, and a minus terminal member d connectable to the minus electrode of the battery a is provided on the bottom plate of the case b.

In the case b, a hook portion e of the battery a is provided so as to protrude horizontally so as to surround the terminal member c, and the opposite side of the hook portion e has an appropriate elasticity capable of expanding outward. The holding projection f is provided. And each terminal member c, d
The terminal pins g projecting below the case b are projected, and each terminal pin g is fixed to a predetermined position of the wiring board by soldering.

The battery a need only be fitted into the housing space of the case b between the hooking portion e and the hooking projection f. The positive electrode of the battery a contacts the terminal member c, and the battery a The negative electrode is in contact with the terminal member d and can be energized, and the battery a is held by the hook e and the hook f.

In the above-described battery holder, the battery a can be exchanged personally. However, when the battery a is fitted into the case b, the battery a is hard to be fitted by the hooks e and the hook projections f. In this case, a downward pressure is applied to the entire case b, which causes the terminal pin g to break or cause poor contact. When the battery a is taken out of the case b, the battery a is caught by the hook portion e or the hook protrusion f and the case b is pulled up, so that the terminal pin g comes out of the wiring board or the contact is poor. Was causing the problem.

[0009] In view of the various problems of the conventional battery holder described above, the applicant of the present invention disclosed in Japanese Patent Application No. 10-301732 on October 9, 1998, the battery was inserted into the case without applying excessive pressure. It provides an improved battery holder that is easy and allows the battery to be easily removed.

This battery holder is shown in FIG.
(B), a peripheral wall B is continuously provided on a circular bottom plate A, and one side surface of a case C made of an insulating material such as a synthetic resin formed in a disk shape as a whole has a square shape. On the peripheral wall B at a position symmetrical to the projection D, a latching projection E having an L-shape and having an upper end horizontally directed inward is formed. A positive terminal member F that can be connected to the positive electrode of the battery is attached to the protrusion D, and a negative terminal member G that can be connected to the negative electrode of the battery is attached on the bottom plate A.

As shown in FIG. 15, a terminal member F having elasticity and made of a conductive metal material is provided with a terminal semi-circularly curved forward in front of a fixing portion H having a downward U-shape. It has a shape in which the plates I are integrally connected, and terminal pins K for connection to the wiring board are provided below the connecting plates J on both sides of the fixing portion H in an extended manner. The connecting plates J on both sides are inserted and fixed into slits (not shown) formed on both sides of the protrusion D, the terminal pins K are protruded below the protrusion D, and the terminal plate I is provided for the battery in the case C. It is arranged so as to face the accommodation space.

Further, as shown in FIG. 16, a terminal member G having elasticity and made of a conductive metal plate is provided with connecting plates M at right angles to both sides of a rectangular plate body L in a downward direction. The connection plate M is provided with terminal pins N for connection to the wiring board in an extended manner. A terminal plate O is formed at the center of the plate body L. The terminal plate O is formed by cutting and raising the front end of the plate L from the connection base. The two connecting plates M are inserted and fixed in slits (not shown) formed in the bottom plate A of the case C, and the terminal pins N protrude below the case C.

In the above-described battery holder, as shown by a chain line in FIG. 17, the battery P is inserted obliquely below the hooking projection E, and then the battery P is placed horizontally and the terminal plate I is projected. When the battery P is fitted into the housing space of the case C so as to be pushed out to the part D side in an inclined manner, the battery P is housed between the latching projection E and the terminal plate I of the terminal member F, and the battery P The positive electrode is connected to the terminal member F and the battery P
Is connected to the terminal member G.

In particular, a horizontally long latching hole Q into which the side surface of the battery P can be inserted is formed at the center of the terminal plate I, so that the battery P is located between the latching projection E and the latching hole Q. It will be held (solid line position in FIG. 17). To remove the battery P from the case C, the terminal plate I may be pulled in an inclined manner toward the protruding portion D with a fingertip, and the side surface of the battery P is disengaged from the hook hole Q, and the terminal plate O of the terminal member G is provided. It is pushed upward by the upward elastic pressing force, and can be taken out.

[0015]

The above-mentioned improved battery holder has the advantage that no excessive pressure is applied to the entire holder when replacing the battery, but the positive terminal member F is connected to the case C. Since a square-shaped projection D for fixing the case C is required, the shape of the entire case C becomes large and the structure becomes complicated, so that there is a problem that the manufacturing cost is increased. The positive terminal member F is
Since the fixing portion H and the terminal plate I having the downward U-shape are integrally connected, the number of manufacturing steps, especially the number of processing steps, increases, and the manufacturing cost increases.

In addition, not only the improved type holder but also conventional general battery holders can be accommodated regardless of the polarity of the battery. That is, as shown in FIG. 18, the battery P has a minus electrode P2 integrated with a plus electrode P1 in an insulated state. Normally, when housed in a holder, the plus electrode P1 is set up and the minus electrode P2 is set down. However, the plus and minus electrodes may be set upside down or upside down without noticing. In this state, the negative electrode P1 and the negative terminal member G on the case C side are not connected to each other, so that the power is not supplied. Therefore, the devices do not operate, and it takes time to find out the cause of the non-operation. Was something.

Further, as described above, in the conventional battery holder, the battery P is fitted into the case C in an oblique state with the negative electrode P1 facing downward. At this time, as shown in FIG. However, the positive electrode P1 and the negative electrode P2 of the battery P are connected to the negative terminal member G of the case C.
May be touched at the same time and short-circuited. This short circuit shortened the battery life and destroyed the memory of the equipment.

In view of the above-mentioned various problems of the conventional battery holder, the present invention simplifies the entire structure, reduces the size and the manufacturing cost, and does not set the battery electrodes upside down. It is intended to provide a battery holder. Another object of the present invention is to provide a battery holder that does not cause a short circuit when a battery is set in the holder.

The terminal pins 11 and 17 projecting downward from the bottom plate 5 of the case 2 are fixed to predetermined positions on a wiring board (not shown) by soldering. To set a battery in the case 2 of the holder 1 installed on the wiring board, as shown in FIG.
Is inserted obliquely below the hooking projection 8 with the negative electrode 23b facing downward, and the lower surface of the opposite end of the battery 23 is placed on the upper surface of the hooking piece 12 of the terminal member 3 and pushed down.

In the battery 23, a curved surface 23c is formed on the side surface of the plus electrode 23a toward the minus electrode 23b, and the upper surface of the hooking piece 12 is inclined downward. The curved surface 23c abuts on the plate 9 of the terminal member 3, and the plate 9 is pushed and bent to the left in FIG.

The plate 9 slides on the hooking piece 12 and is pushed out while being further inclined or curved outward. When the battery 23 is further pressed down, the curved end of the battery 23 passes through the hooking piece 12 and rests on the terminal plate 18 of the terminal member 4.

When the battery 23 passes through the hook piece 12, the terminal member 3 returns to the normal vertical position. Therefore, as shown in FIG. 8, the terminal plate 18 is flattened against the upward elasticity. When the battery 23 is pushed down, the battery 23 is accommodated in the circular space of the case 2 between the terminal member 3 and the hooking projection 8. Accordingly, the positive electrode 23a of the battery 23 comes into contact with the positive terminal member 3 and the negative electrode 23b of the battery 23 comes into contact with the negative terminal member 4, so that a current is supplied.

It is characterized in that a contact-preventing projection 26 swellable horizontally is formed.

As described above, a part of the upper surface of the bottom plate 5 is
When the battery 23 is inserted obliquely into the case 2, the plus electrode 23 a and the minus electrode 23 b of the battery 23 may come into contact with the terminal member 4. No short circuit phenomenon occurs. In this case, the hole 25 may have at least a vertically long shape along the connecting plates 16 on both sides, and the protrusion 26 can prevent the terminal member 4 from contacting the battery 23.

FIGS. 11 (a) and 11 (b) show another embodiment of the positive terminal member 3, and the same parts as those in the above embodiment are denoted by the same reference numerals. In this embodiment, an upward U-shaped notch is formed on the side surface of the plate body 9 to form a terminal plate 27, and this terminal plate 27 is provided so as to protrude upward in the same direction as the hook plate 12. Features.

By adopting such a configuration, FIG.
As shown in (2), when the battery 23 is fitted into the case 2, the side surface of the plus electrode 23a of the battery 23 comes into contact with the terminal plate 27, so that the connection state between the terminal member 3 and the plus electrode 23a of the battery 23 is improved. At the same time, the battery 23 is pushed in the direction of the locking projection 8 by the elastic action of the terminal plate 26, so that the battery 23 can be stably held.

FIG. 13 shows still another embodiment of the plus side terminal member 3, and the same parts as those in the above embodiment use the same reference numerals. In this embodiment,
The plate body 9 is characterized in that a curved surface 28 is formed along the circumferential side surface of the positive electrode 23a of the battery 23.

With such a configuration, FIG.
As shown in (2), when the battery 23 is accommodated in the case 2, the contact area between the plate 9 and the positive electrode 23a of the battery 23 increases, and the connection state becomes stable. When the plate body 9 is curved as described above, the connecting plate 1 continuously provided thereunder.
0 may be a flat plate or may be curved in the same direction as the plate 9. When the connecting plate 10 is curved, the slit 13 formed in the bottom plate 5 of the case 2 may be curved in the same manner as the connecting plate 10. In addition, terminal pin 1
