Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a battery storage device that is removably housed in a device housing, and its purpose is to simplify the configuration of the device and make it easier to assemble, as well as to make it easier to insert and remove batteries. The goal is to make it easy to do.

In a conventional battery storage device, an electrode terminal for extracting voltage from the battery is built into a case that houses the battery, and a terminal that comes into contact with the electrode terminal is built into the housing of the device in which the case is housed. Because of this structure, the number of parts is large, making it difficult to assemble, and when inserting the battery into the case, the electrode terminals get in the way and are difficult to insert.

The present invention is intended to eliminate such conventional drawbacks, and one embodiment thereof will be described below with reference to the drawings.

FIG. 1 shows the appearance of the battery storage device of this embodiment.
Battery storage case 1 is cassette type tape recorder housing 2
This shows the state in which the device is about to be installed.

Two batteries 3 are inserted in series in the battery storage case 1, and these batteries 3 are provided with elastic lips 4 integrally provided in a staggered manner on both sides of the battery insertion opening of the case 1. It is held in place. FIG. 2 shows a cross section taken along the line A--A in FIG. 1, and the battery 3 housed in the battery storage case 1 is held by the ribs 4 to prevent it from coming off.

The rib 4 is normally located at the position shown by the dotted line in the figure, and when the battery 3 is inserted, it is moved to the position shown by the solid line and exerts an elastic return force. The housing 2 is composed of an upper case 2a and a lower case 2b. The upper case 2a is composed of a synthetic resin base A with a metal cover attached, and the lower case 2b is composed only of a metal cover. There is. A guide C for inserting the battery storage case 1 into the housing 2 is integrally provided on the base A of the upper case 2a. Third
The figure shows a partial cross section of the battery storage case 1 completely attached to the housing 2, and the battery storage case 1 has a recess 1a along the side surface of the housing 2. The locking member 5 is positioned by engaging with a claw portion 6 of a locking member 5 which is attached so as to be able to slide freely, and has a structure that prevents the locking member from accidentally protruding outward from the casing 2.

In this case, the front end surface of the case 1 constitutes a part of the outer surface of the housing 2. A terminal plate 7 in contact with the positive electrode surface u of the battery 3 is provided on the back side of the front end surface of the battery storage case 1 in a position parallel to the locking member 5, and the protrusion 8 of the terminal plate 7 and the housing 2 A connecting piece 10 made of a leaf spring fixed to the printed circuit board 9 and connected to the printed circuit board 9 comes into contact with the connecting piece 10 to allow current to flow therethrough. When viewed from the side, the terminal plate 7 has an inverted L-shape as shown in the figure, and the portion where the protrusion 8 is provided is bent into a U-shape and fitted into the opening peripheral wall of the battery storage case 1. The portion that contacts the positive electrode protrusion of the battery is held between the protrusion 1b provided on the case 1 and the front wall of the case 1. Also, as is clear from the figure, the length L1 inside the battery storage case 1 is set larger than the sum L2 of the lengths of the two batteries 3 stored therein and the thickness of the terminal plate 7. inside the rear end of case 1 and battery 3.
A gap δ is created between the battery and the negative electrode (c), making it easier to store the battery. Further, an electronic terminal board 12 equipped with a spiral coil spring 11 that comes into contact with the negative electrode of the battery 3 is attached to a groove provided in the housing 1 at a position facing the terminal board 7, and this terminal board 12 is printed It is connected to the board 9.

When the battery storage case 1 is attached to the housing 2, the coil spring 11 is pressed against the negative electrode of the battery 3 through the through hole 1C provided in the case 1, and presses the front end surface 3 of the battery case 1. The force that tries to push the case 1 out of the housing 2 moves. FIG. 4 shows a state in which the locking member 5 is pushed against the force of a spring (not shown) and the case 1 is unlocked.

That is, a state in which the battery storage case 1 is pushed outward from the housing 2 by the pressing force of the coil spring 11 is shown. At this time, the protrusion 8 of the terminal board 7 separates from the connection piece 10,
Electrical connection is broken. FIG. 5 shows a cross section taken along the line B--B in FIG. 3, and FIG. 6 shows an enlarged view of the contact state between the battery 3 and the coil spring 11 in FIG. 5.

FIG. 7 shows how the coil spring 11 is attached to the battery terminal plate 12.
12a also has a spring 11 attached thereto.

Further, a bent piece 13 having spring properties is provided at the corner of the outer periphery of this battery terminal plate 12, and when the battery 3 is not stored in the battery storage case 1, the bent piece 13
The rear end surface portion 14 of the battery storage case 1 comes into contact with the bent piece 1.
The structure is such that the battery storage case 1 is pushed out of the casing 2 by using the elastic return force of 3. As explained above, in the battery storage device of the present invention, the battery storage case does not have a coil spring for taking out the power source, but is provided on the case side so that when the case is stored in the case, the coil spring is attached to the end face of the case. Since it is configured to be inserted through the through hole and pressed into contact with the battery, the elastic contact force of the coil spring ensures continuity, and at the same time, the force of the coil spring can be used to push the battery storage case out of the case. In other words, it is possible to realize a sliding type battery storage device with a simple configuration using only one coil spring.

Furthermore, by making the length of the battery storage case longer than the length of the battery row, when the battery storage case is removed from the housing, the elastic force of the coil spring is no longer acting on the batteries in this case, making it extremely easy to use. The battery can be removed from the case. This also applies to the case of storing batteries in the case. In addition, a bent piece provided on the terminal board inside the case comes into elastic contact with the end face of the battery storage case, and by pressing the case in the same direction as the coil spring, when there is a battery in the case, the can be pressed by a coil spring and a bending piece, and even when there is no battery inside the case, the case can be pushed out by the bending piece, and has the excellent property of being extremely easy to operate. It is.
