Problems solved by technology

However, the thinner the bottom wall is, the more difficult it is for the resin to flow to the thin bottom wall during molding, so the moldability deteriorates.
Therefore, the bottom wall must have a thickness of more than a certain level, so thinning the bottom wall and reducing the height are limited.

Embodiment Construction

[0026] Hereinafter, a battery holder for a coin type battery (hereinafter simply referred to as a battery holder) according to the present invention will be described with reference to the drawings. figure 1 It is the first embodiment of the battery holder of the present invention, (a) is a plan view, (b) is along figure 1 Sectional view of line 1b-1b. figure 2 yes figure 1 A perspective view of the battery holder shown, figure 2 (a) is a perspective view from above, figure 2 (b) is a perspective view seen from below. Refer to the following figure 1 and figure 2 Be explained.

[0027] The battery holder 1 has an insulating case (hereinafter, simply referred to as a case) 2 . The case 2 is integrally molded from insulating resin using a mold. The case 2 is substantially rectangular, and has mounting portions 4 having through holes 6 for mounting contacts described later at the four corners. A notch 10 is formed in each side wall 8 in the longitudinal direction of t...

Abstract

PROBLEM TO BE SOLVED: To realize a further low height and improve molding performance in a battery holder that is mounted on a substrate. SOLUTION: The battery holder comprises a housing 2, a contact 28, and a contact 50. A housing section 22 which penetrates vertically is formed in the housing 2 and a bottom wall is not formed, and an opening 9 is formed. The battery is housed in the housing section 22 and supported by the battery holder 1 by a pawl 38 of the contact 28 and a protrusion 26 of the housing section 22, and is electrically connected to a spring member 30 of the contact 28 and a contact piece 54 of the contact 50. Since there is no bottom wall and an opening penetrated in vertical direction is formed, the battery holder 1 becomes low height and molding performance is improved as there is no thin bottom wall.

Description

technical field [0001] The present invention relates to a battery holder for button batteries, and more particularly to a battery holder for button batteries used in small electronic devices such as cellular phones, game machines, and portable information terminals. Background technique [0002] Such a battery holder for a coin cell is used mounted on a printed circuit board (hereinafter simply referred to as a board) arranged in a small device such as a mobile phone, for example. Typically, the space within the device in which such a battery holder is installed is very tight. Therefore, it is required to reduce the height of protrusion from the substrate as much as possible during substrate mounting. [0003] As an example of such a battery holder, a battery holder disclosed in JP-A-10-188932 is known. The battery holder has an accommodating portion for receiving a coin-type battery, that is, a button-type battery, and has a contact member in contact with a side surface c...
