Abstract

PURPOSE:To prevent an internal circuit from being damaged by static electricity, and to obtain a signal transmission device with superior operability, by constituting a signal output terminal by using a conductive rubber material, and constituting a device so that a contact bar press-contacts on the output terminal, thereby, electrical connection can be obtained. CONSTITUTION:At the time of inserting an electronic equipment 2 into a containing part 3, the signal output terminal 11 press-contacts on the tip part of a conductive bar 12 by the dead weight of the electronic equipment 2, passing through a hole part 13a. At this time, since the signal output terminal 11 is formed with the conductive rubber, conductivity can be increased by applying pressure. As a result, the electrical connection between the signal output terminal 11, and the conductive bar 12, can be obtained. Meanwhile, at the time of carrying the electronic equipment 2, since no pressure is applied on the signal output terminal 11, the signal output terminal 11 has an insulating characteristics, and it is possible to prevent the charge of external static electricity voltage from invading to the inside through the signal output terminal, and to prevent electrostatic breakdown from occurring.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a signal transmission device for two uses, such as mounting a portable electronic device and retrieving data stored in the electronic device to the outside.

2. Description of the Related Art Conventionally, the transmission device 1 shown in FIG. 'J The electronic device 2 having the knob 2a is attached and a signal is transmitted to the external device 10. FIG. 3 shows the configuration of a conventional transmission device. In the figure, 3 is a housing, 3a is a storage part of the housing 3, 4 is a signal output terminal provided at the bottom end of the electronic device 2, 5 is a spring, 6 is a contact bar, 7 is a signal output part, and 8 is a bottom part. It is.

In the above-mentioned conventional example, the electronic device 2 is mounted in the storage part 3a of the housing 3, and the metal signal output terminal 4 provided at the lower end of the electronic device 2 is used.
Then, a contact rod 6 stored in the bottom 8 of the storage section 3a and biased upward by a spring 5 and having a sharp tip 6a is brought into pressure contact with the signal output terminal 4 to make electrical contact, thereby forming a signal output section. 7 to an external device 10.

In this way, signals can be extracted from the electronic device 2 even with the conventional signal transmission device.

Problems to be Solved by the Invention However, since the metal signal output terminal 4 of the above conventional signal transmission device is exposed to the outside, there is a problem that the internal circuit of the electronic device 2 is destroyed by static electricity. In order to prevent this, an insulating gasket is provided using a separate component made of rubber or the like to cover the signal output terminal 4, which poses problems of increased cost and poor operability.

The present invention solves these conventional problems,
The internal circuit will not be destroyed by static electricity, and
The object is to provide a signal transmission device with good operability.

Means for Solving the Problems In order to achieve the above object, the present invention comprises a signal output terminal provided for outputting a signal from an electronic device using a conductive rubber material, and when taking out a signal, a contact rod outputs a signal. It is constructed so that it can be pressed into contact with a terminal to obtain an electrical connection.

Function: Since the present invention is constructed as described above, the signal output terminal has insulating properties when no signal is being extracted, and when the negative signal is being extracted, the conductivity of the conductive rubber increases and an electrical connection can be obtained.

Embodiment FIGS. 1(a) and 1(b) show the structure of an embodiment of the present invention. In these figures, 11 is a pair of signal output terminals provided on the bottom surface of the electronic device 2 and made of conductive rubber and connectable to the outside via a hole 13a, and 12 is provided on the bottom 8 of the housing 3. , is a conductor rod that is biased upward by a spring 5 and has a flat tip 12a. The tip portion 12a passes through a hole 13a provided in the bottom of the storage portion 3a and protrudes upward. The same reference numerals as in other FIG. 3 represent the same names.

Next, the operation of the above embodiment will be explained. When the electronic device 2 is inserted into the storage section 3a as shown in FIG. 2, the signal output terminal 11 passes through the hole 13a due to the weight of the electronic device 2.
It is pressed against the tip 12a of the conductive rod 12. At this time, since the signal output terminal 11 is made of conductive rubber, applying pressure increases the conductivity as well known, and as a result, an electrical connection is obtained between the signal output terminal 11 and the conductive rod 12. It turns out.

On the other hand, when the electronic device 2 is carried, no pressure is applied to the signal output terminal 11, so the signal output terminal 11 has an insulating property, and the electric charge is transferred to the signal output terminal even when an external static electricity voltage is applied. It can prevent electrostatic discharge from entering the interior via the battery and causing electrostatic damage.

The flat tip 12a of the conductor rod 12 is because it is better to press the conductive rubber against the signal output terminal 11 over a wider area than to locally track the force with a sharp tip. This is because reliable contact can be obtained.

Effects of the Invention As is clear from the above embodiments, the present invention uses conductive rubber as a signal output (input) contact of an electronic device, and has sufficient conductivity when in use, and has internal conductivity when not in use. It functions as an insulating packing that protects the circuit, and has the effect of providing a signal transmission device that is cost-effective and easy to operate.
