Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a fixing structure on a substrate side of a battery.
[0002]
[Prior art]
In an electronic device using a battery such as a dry battery, in order to stabilize the conduction resistance of the battery, it is desired that the battery maintain a good holding state without shaking. For example, conventionally, a dry battery fixing structure is a structure in which the external shape of the dry battery is constrained, or the dry battery is sandwiched by pressing the positive and negative terminals of the dry battery. In a normal structure that constrains the outer shape of a dry cell, if a dimensional tolerance of the dry cell size is taken into consideration, a design having a certain amount of allowable gap (so-called looseness) must be made. In addition, with a structure that holds the terminals with only the pressing force, it is difficult to prevent the dry battery from moving due to external force such as impact, so it is considered that contact failure will not occur even if there is some movement. It is necessary to keep.
[0003]
Japanese Patent Application Laid-Open No. 2001-243934 discloses a battery housing box in which a helical spring is fixed to be held in contact with the negative electrode of a dry battery by applying an elastic restoring force. This spiral spring is formed by winding a metal wire having electrical conductivity in a conical spiral shape. Such a spiral spring and a battery often cause poor contact and damage the battery.
[0004]
[Problems to be solved by the invention]
The present invention basically has a structure in which the terminal of the dry battery is held between the terminals, securely holding the dry battery, maintaining stable contact even when there is vibration, etc. An object of the present invention is to provide a fixing structure that can be accommodated in a stable state.
[0005]
[Means for Solving the Problems]
The present invention has been made to solve the above-described problems, and is a battery fixing structure characterized by taking the following technical means. That is, the present invention is a battery fixing structure characterized in that a conduction terminal in contact with an end portion of a battery is provided with two projections in contact with the battery and an urging portion that presses the protrusion against the battery. It is.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0007]
FIG. 1 is a perspective view showing a fixing structure of a dry battery according to an embodiment of the present invention, and FIG. 2 is a plan view thereof. Since the conductive terminal 10 that contacts the end of the dry battery has two round heads arranged in parallel, even if the protrusion 11 is slightly inclined with respect to the bottom surface of the battery, a good contact state is maintained. The urging portion 12 is made of, for example, an elastic plate bent into a U shape, and is urged in a direction in which a pressing force is applied to the protrusion 11 by the bending elasticity of the U-shaped bent portion 14. The shape of the urging portion 12 is not limited to a shape bent in a U shape, and may be, for example, a leaf spring, a disc spring, a coil spring, a bamboo spring, or the like.
[0008]
The conductive terminal 10 has a spring property that is urged in the long axis direction of the dry battery, and protrudes two round head protrusions 11 on the upper surface thereof to contact the electrode of the dry battery. The gap in the terminal direction at both ends of the dry battery suppresses the generation of play (backlash) due to the spring property of the conductive terminal 10.
[0009]
The dry battery fixing structure of the present invention is used as a conductive terminal 10 inside the set (anti-battery insertion side) in contact with the dry battery, and is provided so that the two protrusions are in contact with the dry battery, and the protrusions are pressed against the battery. The conduction resistance is stabilized by having a structure including an urging portion that makes the terminal shape round. Further, by following the movement of the dry battery, even when the electronic device is subjected to vibration or impact from the outside, the dry battery and the battery terminal come into contact at two points, and the dry battery can be held so as not to move inside the set.
[0010]
【The invention's effect】
Since the battery fixing structure of the present invention is configured as described above, the battery can be securely held, can maintain a stable contact resistance even when there is vibration, and stably extends the battery life. be able to.
