Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a terminal connection structure for electronic equipment, and more particularly, to a terminal connection structure for checking electronic equipment.

[Technical background of the invention]

In general, in order to improve the performance and quality of electronic devices, various checks are performed on the operation and performance of electronic devices during or after manufacturing, but many system checks take time. They are often designed with terminals so that checks can be performed quickly and efficiently. For example, a selective call receiver is designed to provide an efficient check system by shorting the check terminal electrically connected to a specific terminal of the control LSI and the ground terminal. For this reason, conventionally, a terminal connection structure for short-circuiting the check terminal and the ground terminal, as shown in FIGS. 3 and 4, has been adopted.

That is, a pair of circuit-side terminals 3 and 4 connected to a check circuit (not shown) are attached to a wall plate 2a at one end of the battery holder 2 disposed inside the case body 1. Further, a U-shaped connection terminal 7 is fixed to one end side of the check battery cover 6' to which the case body 1 is attached instead of the battery cover 5 during the check operation. Further, the two tongue pieces 7a and 7b of the connection side terminal 7 are bent as shown in the figure.

In addition, in the figure, 8 is a cover attached to the case body 1, and the case body 1 and the cover 8 fit together the groove 1a formed in the case body 1 and the jetty 8a formed in the cover 8. It is attached by this. Similarly, the battery cover 5 or the check battery cover 6', the case body 1, and the cover 8 have grooves 1a and jetties 5a, 6' formed therein.
a, jetty 8b and corresponding covers 5, 6'
It is attached by fitting into a groove formed in the. Then, by attaching the check battery cover 6' to the case body 1 with the cover 8 attached, the fourth
As clearly shown in the figure, the tongue pieces 7a and 7b of the connection side terminal 7 are inserted between the circuit side terminals 3 and 4 and the cover 8. By doing so, the tongue piece 7a and the circuit side terminal 3, and the tongue piece 7b and the circuit side terminal 4
are reliably pressed together by the elastic force of the bent portions formed on the tongues 7a, 7b. Therefore,
The circuit side terminals 3 and 4 are connected via the connection side terminal 7, the check circuit is short-circuited, and the check operation is then performed by the inspector.

[Problems with background technology]

By the way, in the terminal connection structure configured as described above,
As is clear from FIG. 4, in order to insert the bent tongue pieces 7a and 7b of the connection side terminal 7 between the upper parts of the circuit side terminals 3 and 4 and the cover 8 located above them. Because of this, the thickness of the case body 1 increases, which causes a serious problem in portable selective call receivers that are desired to be small. Was.

[Purpose of invention]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, it is an object of the present invention to provide a terminal connection structure that can achieve miniaturization of electronic devices.

[Summary of the idea]

Therefore, in the present invention, when the check battery cover is attached to the case body with the cover attached, the cylindrical battery housed in the case body and the case body with the cover attached and the check battery cover are combined. A pair of terminals are arranged spaced apart from each other in a longitudinally extending area of a substantially triangular prism-shaped area formed by the battery, and a contact terminal installed on the check battery cover is brought into contact between the pair of terminals. The above object is achieved by configuring the pair of terminals to be electrically connected to each other.

[Example of idea]

EMBODIMENT OF THE INVENTION Hereinafter, the structure of this invention will be described in detail based on the drawing which shows one Example.

Figures 1 and 2 show examples in which the terminal connection structure according to the present invention is adopted in a selective call receiver, and have the same function as the conventional terminal connection structure shown in Figures 3 and 4. are given the same reference numerals, and some explanations thereof will be omitted.

The case that constitutes the external appearance of the selective calling receiver includes a case body 1, a cover 8 and a battery cover 5 that are detachably attached to the case body 1, and the case has a cylindrical battery 9. It is composed of a battery holder 2 for holding, a case body 1 containing a printed wiring board 10, etc., and a cover 8 that covers the open part of the case body 1, leaving only the battery holder 2. The battery cover 5 is used during normal use, and a checking battery cover 6 is attached in place of the battery cover 5 when checking reception sensitivity. As shown in the cross section of FIG. 2, this check battery cover 6 has an upper surface flush with the cover 8, and both edges of the back surface are formed so as to extend along the upper circumferential surface of the battery 9. Overhanging portions 6b and 6c having a substantially triangular cross-sectional shape are formed on the overhanging portions 6b and 6c, and an end portion 6d (the first
In FIG. 1, a contact 11 made of a round rod made of a conductive material is installed along the longitudinal direction of the check battery cover 6. Note that the battery cover 5 is
It goes without saying that the contact 11 is removed from the check battery cover 6, and its shape is basically the same as the check battery cover 6. On the other hand, on the printed wiring board 10 disposed inside the case body 1, a pair of circuit-side terminals 12 made of conductive and elastic round bars are provided at a portion facing the wall plate 2a on one end side of the battery holder 2. ，
13 are respectively planted facing upward, and these circuit side terminals 12 and 13 are connected to the contactor 11 described above.
They are arranged in parallel and spaced apart from each other with an interval slightly narrower than the outer diameter of the tubes. Furthermore, the circuit side terminal 12,
13, the upper part of which corresponds to the part occupied by the contact 11 when the check battery cover 6 is attached, that is, the extension area of the approximately triangular prism-shaped protrusion 6b of the check battery cover 6. The mounting position and height with respect to the printed wiring board 10 are set so as to do so.

In the above configuration, when the check battery cover 6 is attached to the selective call receiver, the contact 11 pushes the pair of circuit side terminals 12 and 13 against its elastic force, as shown in FIG. The circuit side terminals 12 and 13 are connected via the contactor 11, and the check circuit is short-circuited. Further, at this time, the circuit side terminals 12 and 13 strongly abut against the contactor 11 due to their elastic return force, so that the electrical connection becomes reliable.

In this embodiment, the circuit-side terminals 12 and 13 and the contact 11 are connected to each other in the extended area of the overhanging part 6b of the check battery cover, but the overhanging part 6c opposite to the above-mentioned overhanging part 6b is connected. It can also be provided in an extended area.

In this embodiment, the circuit side terminals and contacts are made of round rods, but each terminal may be made of a suitable shape other than round rods, for example, a plate-like member, as long as the object of the present invention can be achieved. Of course it is possible.

[Effect of idea]

As detailed above, according to the terminal connection structure according to the present invention, when the check battery cover is attached to the case body, the cylindrical battery housed in the case body and the case body and the check battery cover are connected to each other. By configuring the pair of terminals to be connected in the extended area of the approximately triangular prism-shaped area formed by the The thickness of the electronic device can be reduced without causing the disadvantages of the conventional terminal connection structure, which increases the thickness due to the provision of terminals, thereby achieving miniaturization. Furthermore, since the above-mentioned approximately triangular prism-shaped area is a dead space that has not been used in the past, even if terminals are placed in this area and its extension area, various functions such as battery storage may be hindered. do not have.
