JP2000102179A - Waterproofing structure for battery terminal - Google Patents

Abstract

PROBLEM TO BE SOLVED: To highly efficiently waterproof battery terminals by avoiding the occurrence of short circuits between the battery terminals or the imperfect contact of the terminals caused by electric erosion, by constructing each set of probe and battery terminal in an independent waterproofing structure by press-contacting ribs with a battery housing section. SOLUTION: A packing 109 has ribs 109a, 109b, and 109c. The ribs 109a have oval shapes so that the ribs 109a may be press-contacted with a battery housing section 106 including battery terminals 110. The ribs 109b and 109c are respectively press-contacted with sleeves 107b and the holes of a chassis 101. When the packing 109 is constructed in such a way, the imperfect contact of the battery terminal 110 caused by electric erosion can be avoided, because the ribs 109a-109c can prevent the infiltration of water. Since each battery terminal section is constructed in an independent waterproofing structure by press-contacting the ribs 109a with the battery pack 106 including the battery terminals 110 and probes 107 corresponding to the ribs 109a, the occurrence of short circuits caused by water can be avoided even when the ribs 109a are cracked.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a waterproof structure of a battery terminal of an electronic device using a battery as a power source, for example, to a waterproof structure of a battery terminal of a wireless device.

[0002]

2. Description of the Related Art Electronic equipment using a battery as a power source includes a battery housing and a main body. A plurality of battery terminals attached to the battery housing correspond to a plurality of probes mounted on the main body, respectively. It is to be connected.
Detailed structures of a battery terminal portion of a conventional electronic device are shown in FIGS. In all of the conventional examples shown in FIGS. 7 to 9, a probe 7 composed of a sleeve 7b, a spring 7c, and a plunger 7a, which is fixed to the printed board 5 by soldering, is an integral part of the base 8, and a packing 9 is provided as the probe. It is structured to be fixed while being sandwiched between the chassis 7 and the chassis 1. The difference between the structures of the conventional examples is the shape of the packing 9.

The packing 9 shown in FIG. 7 has a shape without ribs for waterproof partitioning. The packing 9 shown in FIG. 8 has a shape having one annular rib 9 a that collectively includes the plurality of probes 7 on the main body 11 side, and has a structure in which the rib 9 a is pressed against the battery housing portion 6. The packing 9 shown in FIG. 9 has a shape having an annular rib 9a around the main body 11 side probe 7 corresponding to each battery terminal 10 on the battery storage section 6 side.
It is structured to be in pressure contact with the side conduction terminal 10.

[0004]

Problems that occur in a battery terminal portion of a conventional electronic device will be described with reference to FIGS. In the case of FIG. 7, since there is no rib for waterproof partition, the main body 1
Short-circuit caused by the flow of electricity between the battery terminals 10 by using water as a medium when water invades between the battery housing 1 and the battery housing 6;
Poor contact due to electrolytic corrosion of the battery terminal 10 occurs. In the case of FIG. 8, if there is any crack in the rib 9 a, water enters between the main body 11 and the battery accommodating portion 6, and a short circuit occurs due to electricity flowing between the battery terminals 10 using water as a medium. Contact failure due to electrolytic corrosion of the terminal 10 occurs. In the case of FIG. 9, even if there is no crack in the rib 9 a, the water enters the space 13 between the packing 9 and the battery housing 6 by going around the outer circumference of the rib 9 a, and as a result, between the battery terminals 10. Short-circuiting due to the flow of electricity using water as a medium and poor contact due to electrolytic corrosion of the battery terminal 10 occur.

Accordingly, the present invention avoids short-circuiting of a battery terminal caused by intrusion of water between the main body and the battery housing and poor contact due to electrolytic corrosion, and significantly improves waterproof performance. It is intended to provide a waterproof structure.

[0006]

According to the present invention, in order to achieve the above object, an annular rib including a set of probes and a battery terminal is provided around each probe, and the rib is pressed into contact with the battery housing. In this way, each probe and battery terminal set has an independent waterproof structure.
