[Prior art]

 BACKGROUND ART Conventionally, a headphone terminal of a headphone stereo, a portable radio, or the like is known as a group of a plurality of electrodes. As shown in FIG. 4, when a headphone terminal 50 (not shown) is inserted into a jack 51 of a headphone stereo, a portable radio (not shown) or the like, a sound is output, and the headphone terminal 50 is connected to the headphone terminal 50. It is said that only one operation (outputting sound) can be performed by inserting the headphone (not shown) terminal 50 into the jack 51 of a stereo or portable radio (not shown). The terminal is known. In addition, the communication device that sends and receives data to and from the host computer by various means for the information stored in the main body of the handheld terminal and the power supply battery for driving the handheld terminal are charged. There is known a charger that also serves as a communication device and that also serves as a charger for the communication device. In this charger that also serves as a communication device, the charging terminal has a one-to-one correspondence with the contact of the power supply battery installed in the handheld terminal.

[0003]

[Problems to be solved by the device]

 However, in the above-described conventional method, only one operation can be performed in one operation, and for example, the terminal 50 of headphones (not shown) is inserted into the jack portion 51 to output sound. , In order to make another function work, it is necessary to provide another means such as another terminal, and a plurality of headphone terminals 50 of the conventional headphone stereo, portable radio (not shown), etc. If the above-mentioned means is used in a miniaturized electronic device, the size of the terminal 50 and the jack 51 will become large and the structure will become complicated. Furthermore, it is necessary to take measures such as miniaturizing the terminal part. Also, in order to perform charging using the charger that also serves as a communication device and measurement of the battery voltage at the same time with one terminal, the shape of the terminal provided on the charger that also serves as a communication device must be used. A means for supporting the above-mentioned multiple functions by providing a complicated one, or a means for supporting the multiple functions by providing several terminals on the handy terminal main body and the charger that also serves as the communication device. Was needed.

[0004]

[Means for Solving the Problems]

 A metal contact divided into at least two parts, a first insulating plate arranged on a dividing surface of the divided metal contact, and a first insulating plate arranged below the divided metal contact. A second insulating plate is disposed, and a metal stopper disposed below the second insulating plate and the at least two-divided multi-divided terminal structure that function differently are proposed. It is a thing.

[0005]

[Action]

 That is, in the present invention, one terminal itself is provided, and two contacts that correspond to different functions are provided to this one terminal so that a plurality of operations can be performed in one operation. .

【Example】

 Hereinafter, details of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an example in which the terminal of the present invention is applied to an optical communication adapter with a charging function for handheld terminals. Reference numeral 1 is a hand-held terminal, and on the upper surface of the hand-held terminal 1, a key unit 2 for inputting data such as the quantity of goods collected at the work site and the collected data. -A display portion 3 for displaying data is arranged. Reference numeral 4 is an optical communication adapter, on which the handheld terminal 1 is placed on a mounting table 5.

Reference numeral 6 is a communication unit for optical communication, which is fitted to a fitting portion (not shown) on the handheld terminal 1 side provided on the back surface of the handheld terminal 1 to perform optical communication. Reference numeral 7 is a terminal portion of the present invention, which projects from the mounting table 5 on the optical communication adapter 4 so as to come into contact with a contact (not shown) provided on the back surface of the handheld terminal 1. It's done. Reference numeral 8 is a bank shape for positioning when the handheld terminal 1 is mounted on the mounting table 5 of the optical communication adapter 4, and is U-shaped, and is attached to the end 9 of the handheld terminal 1. Abut and position. Reference numerals 10, 11, 12, and 13 are display portion LEDs that indicate the operating state of the optical communication adapter 4, and are arranged in the bank-shaped portion of the LED 8. According to the operating state of the optical adapter 4, the LEDs 10, 10, 11, 12 and 13 are turned on or off.

Next, the terminal 7 of the present invention will be described with reference to FIG. First of all, from the configuration, the conical voltage terminal 14 and the charging terminal 15 are formed by molding a metal plate, and an insulating plate 16 for insulating them is provided between the terminals 14 and 15. It is arranged so that it can be sandwiched. A voltage cable 17 and a charging cable 18 are connected to the voltage terminal 14 and the charging terminal 15, respectively, and the battery voltage of a charging battery (not shown) is sensed and the result is detected by the voltage cable. -It is sent to the circuit (not shown) provided on the substrate 19 through the bull 17. The charging cable 18 sends a current to a charging terminal to charge a charging battery (not shown) with the current. Next, the insulating ring 20 and the switch ring 21 are arranged in this order below the voltage terminal 14 and the charging terminal 15.

Functions of the voltage terminal 14 and the charging terminal 15 will be described. FIG. 3 shows that when the handheld terminal 1 is mounted on the optical communication adapter 4, the electrodes (not shown) provided on the back surface of the handheld terminal 1 and the terminals 7 provided on the optical adapter 4. And the terminal 7 provided on the optical communication adapter 4 is pushed downward by the weight of the handy terminal 1 so that the switch ring 21 comes into contact with the switch 22 provided on the substrate 19. Has been done. FIG. 4 is a vertical cross-sectional view of the terminal portion 7 provided on the optical communication adapter 4, and when the hand-held terminal 1 is mounted on the mounting table 5 on the optical communication adapter 4 as described above, the terminal The part 7 is pushed down by the weight of the handheld terminal 1 so that the switch ring 21 and the switch 22 come into contact with each other, and when the handheld terminal 1 is detached from the optical communication adapter 4, the terminal part 7 rises smoothly, as shown in FIG. 6 is a vertical cross-sectional view for explaining a case where the terminal portion returns to the upper side. The projecting portion of the terminal portion 7 provided on the optical communication adapter 4 is a sloped surface so that the head portion of the terminal portion 7 does not project too much. 23 is formed and functions as a stopper.

Also, when assembling the terminal portion 7 of the present invention, it can be assembled relatively easily, for example, the voltage cable 17 is coupled to the terminal 14, and the charging cable 18 is coupled to the terminal 15. The cable and terminal are combined and inserted into the circular holes 24 and 25 provided in the insulating ring 20 and the switch ring 21, and the insulating plate 16 is placed between the terminals 14 and 15. By installing, the terminal can be assembled relatively easily. Although the contact is divided into two in this embodiment, the present invention is not limited to this, and the contact may be divided into three or four, for example. .
