Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a battery connector, and more particularly to a battery connector for an electronic device that allows a battery to be attached or detached with one touch.

(Prior Art) In conventional battery connectors of this type, the contacts are often provided at the abutment part of the battery compartment of electronic equipment, and the mechanism of such connectors has a tendency to have play or loosening in the locking device. If this happens, the contacts on the battery side tend to separate from the contacts on the battery storage section, which tends to cause problems such as instantaneous interruptions.

Therefore, if a contact terminal is provided on the guide surface of the storage section into which the battery is slid and inserted, the movement of the battery is allowed by the amount of play between the battery and the guide surface, but the amount is small. Momentary interruptions are less likely to occur. Furthermore, in this case, by arranging the contact terminals in the sliding direction, the thickness in the direction perpendicular to the sliding direction of the battery can be reduced accordingly, which has the advantage that the entire device can be made compact. can get.

However, although there are many advantages to arranging the contact terminals in a row along the guide surface of the storage part as described above, the contact terminals arranged on the front side in the insertion direction are inserted by the two contact terminals on the battery side. Contact will be repeated twice each during landing and tripping.

Generally, the contact terminals placed on the battery compartment side are made of leaf spring material, etc. Therefore, due to the large number of repetitions, the contact terminals on the front side may be worn out or the springs may deteriorate compared to the contact terminals on the back side. Not only does it cause fatigue and is cheap, but
On the battery side, on the other hand, the contact terminals located on the back side are more likely to wear out, and both pose problems in durability.

[Problems to be Solved by the Invention] The purpose of the present invention is to focus on the above-mentioned conventional problems and, in order to solve them, to suppress the occurrence of instantaneous power outages and contribute to the downsizing of equipment. An object of the present invention is to provide a battery connector that can improve durability.

[Means for solving problems]

In order to achieve such an object, the present invention is arranged in a battery storage part of an electronic device, and when the battery is stored along the guide surface of the battery storage part, each contact point is connected to a plurality of contacts provided on the battery. In a battery connector that enables electrical connection, steps are provided in the storage direction of the guide surface to form a plurality of step surfaces, and contacts are made to protrude from each of the plurality of steps to increase the height of the contacts. is lower than the height of the step, and the battery is provided with a sliding contact surface that can make sliding contact with each of the step surfaces, and the contact terminal plate provided on the sliding contact surface is connected to the corresponding contact provided on the step surface of the battery storage section. It is characterized by being made contactable. .

[Function] According to the battery connector of the present invention, when inserted, the steps on the guide surface provided in the insertion direction cause the contacts provided on the guide surface on the front side of each step to connect to the corresponding contact terminal board on the battery side. The contacts do not come into contact with the contact terminal board located further back, and conversely, the same state is maintained even in the case of tripping, which prevents unnecessary contact between the contacts. Momentary interruptions can be suppressed.

〔Example〕

Embodiments of the present invention will be described in detail and specifically below based on the drawings.

FIG. 1 shows an embodiment of the present invention, in which (A) is an electronic device body, and (B) and (C) are an electronic device (A
) The battery pack (hereinafter simply referred to as a battery) inserted into the battery pack is shown in a different orientation. In other words, (A
), reference numeral 1 is an intelligent terminal or portable intelligent terminal that can independently perform certain types of processing, and the abutment part 28 of the battery storage part 2 is equipped with the battery shown in (B). Engagement hole 5 for engaging the locking claw 4 of No. 3
is provided, and the battery 3 can be fixed to the terminal device 1 by inserting the battery 3 into the battery storage portion 2 from the direction of arrow A and abutting the abutting portion 2A.

Further, in FIG. 1(A), 2B is a guide surface on one side of the storage section 2, and from the guide surface 2B, a first protruding portion 6 and a first protruding portion 6 protrude from the guide surface 2B with two steps as shown. Second
A protruding portion 7 is formed, and a leaf spring type first contact terminal 6A and a second contact terminal 78 are respectively incorporated into the first protruding portion 6 and the second protruding portion 7 as a connector. . Here, these contact terminals 6A and 78 are made of an elastic conductive material such as beryllium copper, and their contacts 6B and 7B are formed at the apex of each bent into a V-shape. The protrusions of the protrusions 6 and 7 from the surface are both set to a constant amount a as shown in FIG. 2A.

On the other hand, on the side surface 3B of the battery 3 facing the guide surface 2B on the side of the terminal 1 described above, there are a first protrusion 6 and a second protrusion as shown in FIG. 1C and FIG. 2A. A first sliding surface 8 and a second sliding surface 9 having a step between the first sliding surface 8 and the second sliding surface 9 are formed,
Contact terminal plates 88 and 98 are embedded in the first sliding surface 8 and the second sliding surface 9, respectively.

Note that it is preferable to use a conductive material such as nickel for the first contact terminal plate 8A and the second contact terminal plate 98.

Therefore, the mounting operation and the tripping operation of the battery 3 using the battery connector configured as described above will be explained. First, in the case of the mounting operation, when the battery 3 is inserted into the battery compartment 2 of the terminal 1 from the direction of arrow A from the state shown in FIG. 2A,
As shown in FIG. 2B, the first sliding surface 8 provided on the side surface 3B of the battery 3 is the same as the first sliding surface 8 provided on the side surface 3B of the terminal battery storage section 2.
The second sliding surface 9 comes into sliding contact with the protruding part 6 and the second protruding part 7 of the second contact 7B provided on the battery storage part 2 side. Since the amount of protrusion a from 7 is set smaller than the height difference, the first contact terminal plate 88 does not come into sliding contact with the second contact 7B.

Thus, by the subsequent insertion operation, the first contact terminal plate 8
The first contact terminals 6A on the side of the storage section 2 were pressed by A, and their V-shapes were deformed and kept in contact with each other, and at the same time, the second contact terminals 78 were deformed by the second contact terminal plate 9A. The batteries 3 are engaged and fixed with each other while maintaining contact with each other in a state where the contact surfaces 3A of the batteries 3 are in contact with the storage portion abutment surfaces 28, as shown in FIG. 2C.

In addition, in the tripping operation, the battery 3 is pulled out in the direction of arrow B (see FIG. 1) in the opposite direction from the state shown in FIG.
Even if it is pulled out to the state shown in Figure B, the second contact terminal 7 on the battery compartment 2 side will not connect to the first contact terminal plate 8A on the battery 3 side and the first sliding contact surface 8.
B never makes contact. That is, as described above, both during the insertion operation and the tripping operation,
The opposing contacts on the side of the storage section 2 and the side of the battery 3 only touch each other once, so that the second contact 7B and the first contact terminal plate 8A are connected to the first contact δB and the second contact terminal. There is no risk of unnecessary wear compared to the plate 9A.

In addition, in the example explained above, the battery connector provided in the storage part 2, that is, the first contact terminal 68 and the second contact terminal 7A, was constructed from one plate spring, but two plates having different natural frequencies may be used. By using a combination of springs, it is possible to further suppress instantaneous interruptions caused by the vibrations.

Furthermore, in the above explanation, the case where there are two sets of contacts has been described, but the present invention is applicable not only to two but also to cases where there are two or more sets of contacts. Of course, the same effect can be obtained by providing the contact protrusion amount a, and the above-mentioned battery connector part can be manufactured and attached separately from the terminal body. This makes it easy to assemble and also suitable for maintenance.

〔Effect of the invention〕

As described above, according to the present invention, contact terminals are arranged in the insertion direction on the guide surface in the insertion direction in the battery storage section of the main body of an electronic device, and a step is provided in the insertion direction of the guide surface. The contacts are made to protrude from each cross section, and the amount of each protrusion is made smaller than the amount of step, and a corresponding step is provided on the battery side, and the contact terminal board is formed on the cross section formed by these steps. This not only makes it possible to avoid unnecessary contact between the contacts when inserting and removing the battery, which not only improves durability, but also reduces the possibility of instantaneous interruptions and allows the battery itself to be flattened. This can contribute to making the electronic device itself more compact.
