Description

Battery holder (hol der)

An embodiment of a battery holder according to the present invention of the drawings is a view showing a battery replaceable position.

The present invention is held between the first electrical contact point and the second electrical contact point in the operating position, at least a portion of which is surrounded by the wall portion of the battery holder, and around the first flow shaft installed in the apparatus container from the operating position to the replaceable position of the battery holder. It relates to a battery holder which can be rotated at and the cell is subjected to an end contact force directed towards the center at the operating position, while not being retained between the positive contact of the battery at the replaceable position.

In a known holder of this kind (the specification of French Patent No. 1,208,847), two battery contacts on which a battery in the holder is to be held are composed of two metal plate springs. After charging a new battery at the replaceable position of the holder, the holder is rotated again and placed in the apparatus container. When the contact surface of the battery is in contact with the contact surface of the plate spring arranged in the device container, the total contact force (end contact force or holding force) is present, so that the rotational movement of the holder to the operating position is dependent on the total contact force on the contact surface of the battery. It must be realized against the frictional forces created by it.

The presence of this total contact force soon is not only easy to give the user the impression that the holder is immovable, but is also undesirable because the risk of tilting the battery in the holder is increased by all initially acting eccentric forces. If several cells are arranged in sequence extending in relation to one another coaxially in the holder, there is a particular risk of tilting one or more cells.

The object of the present invention is that the battery can be easily replaced in the replaceable position of the battery, and the contact force of the battery is the smallest during the rotational movement of the battery to the operating position, and only at the moment when this contact force is almost centered with respect to the battery. It is to provide a battery holder for battery storage that leads to.

For this purpose, the holder according to the present invention is capable of rotational movement about a second flow axis with respect to the holder, and also has a panel provided with a first electrical contact, so that one side of the panel has a battery replacement. During movement of the holder from a possible position to an operating position, it is press-contacted with the wall portion of the device container and is also movable with increasing contact force until the other side of the panel is equal to the end contact force due to the rotational movement of the panel. It is characterized in that the contact with the battery through the contact.

Hereinafter, the present invention will be described in detail with reference to the drawings.

The figure shows a preferred embodiment of a battery holder according to the present invention in a battery replaceable position.

The battery holder 1 shown in this figure is made of synthetic material, for example polystyrene, and comprises a shaped flat bearing (sliding bearing) 3 mounted around a rigidly fixed flow shaft 5. . The flow shaft 5 is made integral with the wall of the device container 7 made of polystyrene.

The apparatus container 7 houses a radio (or radio recorder assembly) powered by, for example, batteries 9, 11, 13, 15, 17 and 19. (Not shown). The battery holder 1 is an elongated rectangular double-sided surface consisting of two mutually parallel long longitudinal walls 23 and 25 projecting perpendicularly to the base 21 and the flat outer surface of the base 21. It is provided with a container opened. At the end of the long direction wall 25 away from the flow shaft 5, a molded flow shaft 27 is provided, and a flat bearing 29 is provided around it. These flow shafts 5 and 27 are parallel to each other and protrude perpendicularly to the outer surface of the bottom portion 21. The flat bearing 29 is made integral with a panel 31 made of polystyrene, for example, and the panel protrudes perpendicularly to the outer surface of the base 21. On the inner side of the bottom portion 21 are two parallel members 33 and 35 shaped corresponding to the cylinders of the cells 9, 11, 13, 15, 17 and 19. Is installed. The member 33 accommodates the cells 9, 11, and 13 arranged coaxially with respect to each other, while the member 35 also extends with respect to each other and arranged coaxially ( 15, 17, and 19 are housed. The rows of cells 9, 11, and 13 are parallel to the rows of cells 15, 17, and 19. The battery container includes two rectangular spaces 39 and 41 separated by a partition 37. The bottoms of these spaces 39 and 41 are surrounded by a common bottom wall 43 and also the top by a common top wall 45 parallel to the bottom wall 43. The back wall 40 common to the spaces 39 and 41 is perpendicular to the walls 43 and 45. One side of the space 39 is by means of a partition 37 extending perpendicular to the walls 43 and 45 and also the other side to a side wall 47 extending perpendicular to the walls 43 and 45. Is surrounded. The side wall 47 and the partition 37 are parallel to each other. Partition 37 and walls 43, 45, and 47 form part of the device container 7. As shown in FIG. The shortest distance between the flow shafts 5 and 27 is smaller than the shortest distance between the flow shaft 5 and the partition 37. The difference between the two distances is slightly greater than the wall thickness of the plain bearing 29 which is visible on the plane perpendicular to the flow axis 21.

The side wall 47 of the space 39 has a positive electrical contact having the shape of the metal plate 49 and a negative electrical contact having a spring shape. These contacts 49 and 51 are electrically connected to a power supply circuit (not shown) of the radio housed in the apparatus container 7. The contacts 49 and 51 (refer to the contact 51) are fixed to the side wall 47 by the hook-shaped projections (see the projection 50) of the side wall 47. The rotatable panel 31 is provided with an extension 55 and is also provided with a conical spiral spring 53 which represents an electrically negative contact. The extension 55 acts as a positive contact electrically. The spring 53 and the extension part 55 are fixed to the panel 31 by the hooked projections of the panel 31.

The panel 31 is provided with a plate-shaped guide member 57 having a short edge 59. This plate-shaped guide member 57 extends perpendicular to the panel 31 and is parallel to the flat outer surface of the bottom portion 21 of the battery holder 1. The standard dimensions of the battery holder are such that the batteries can be arranged in the associated members 33 and 35 with a longitudinal tolerance in the battery replaceable position of the holder. During insertion of the cell, this ensures that even the slightest contact pressure between the cell and the contact is not generated since the cell is not held between the electrical contacts. In the battery replaceable position of the holder, the panel 31 is acute (less than 90 °) by the longitudinal wall 23 of the holder when viewed from the inside of the holder.

When the holder 1 rotates in the space 39, the edge 59 is press-contacted with the edge 62 of the partition 37. The panel 31 rotates in the direction of the battery, and as a result, the tolerance between the battery and the associated contact is first eliminated, and then gradually increasing contact pressure is formed between the battery and the contact.

Since these contacts act almost centrally on the cell then there is little risk of tilting the cell. When the holder 1 is completely rotated into the space 39 (operational position), the panel 31 is located on a surface almost parallel to the partition 37. In the operating position, the holding force (contact force) becomes equal to the end contact force. Assuming that the initial tolerance between the battery and the conical spiral spring in the replaceable position of the battery is the same, the contact force is applied over the predetermined angle of the holder by selecting a predetermined steep slope of the leading edge 59 with respect to the panel 31. The angle which is increased during the rotational movement can be preferably selected. Conical spiral springs offer the advantage of relatively long spring strokes, making it easy to compensate for differences in the dimensions of quasi-cells that occur in practice. The lengths of the spiral springs 51 and 53 must be selected on the one hand so as to compensate for the tolerance of the battery, and on the other hand, so that these springs act almost centrally on the cell.

The optimum length can be found by selecting a predetermined steep slope change of the edge 59. The longitudinal wall 23 of the holder is provided with an extension 63 which closes the space 41 at the operating position of the holder. The extension portion 63 can rotate in response to the force of the spring, and is also a locking member operative with the stop edge 67 installed in the button 69 secured to the vessel 7 of the device. (65). Immediately before the holder 1 reaches its operating position, the longitudinal wall 25 is fixed to the spherical wall 40 and is also fitted against the spiral spring 71 which is thus compressed. The spring 71 releases the stop member 65 from the stop edge 67 by the operation of the button 69 and then exerts a force against the holder 1 again. This spring 71 is only necessary to rotate the holder outward when the battery is not contained in the holder. When the battery is contained in this holder, the spiral springs 51 and 53 tend to loosen while the holder is open, so that the holder is always rotated outward. The space 41 can be used for storage of the main connection cable in this apparatus container, with or without fixed connection or disconnection.

Although the present invention has been described in terms of specific embodiments, it is by no means limited thereto. For example, the flow axis of the holder and the panel may form an axis crossing each other at right angles. For this purpose, a panel rotatable with respect to this holder may be installed in the battery holder according to the specification of the French Patent No. 1,208,807. On the other hand, it is also possible to provide the side wall extended perpendicular to the wall 23 in the longitudinal direction at the end of the holder located in the vicinity of the flow shaft 5. Electrical contacts can be installed on the sidewalls of this type to interact with the fixed contacts of the device container.

The battery holder according to the present invention may be advantageously used to store only one battery. In that case the contacts present on the panel would have to interoperate with, for example, fixed contacts arranged in the device container near the partition 37. It is clear that instead of the above conical spiral springs, several other springs may be used for electrical contacts.

In short, the present invention can rotate around the fluid shaft disposed in the apparatus container from the operating position to the battery replaceable position, while at least one battery is held between the electrical contacts in the operating position, while the battery is replaced. The possible position relates to a battery holder that is not held between electrical contacts. While the holder is rotated from the replaceable position of the battery to the operating position, the contact force applied to the battery is gradually formed by the electrical contact.
