DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for applying current to a battery or other electric equipment, electronic equipment, and other parts (hereinafter collectively referred to as electric parts), and measuring current, voltage or resistance by a four-terminal method. And a conductive contactor used in such a case. 2. Description of the Related Art Conventionally, it is known to apply a constant voltage to an electrical component or electrically measure an electrical component by a four-terminal method. Here, the four-terminal method means that a measurement terminal is directly connected to a supply terminal as shown by a dotted line in FIG. 4, and two wires are connected to a load or a measurement object. It refers to a method of conducting current or measuring voltage by resiliently contacting a load or a measurement terminal.

[0002]

However, in the configuration in which the supply terminal and the measurement terminal are directly connected as described above, a voltage drop occurs due to the resistance between the terminal and the load, and a predetermined voltage is applied to both ends of the load. There are disadvantages that are not. 4 on the load side
Since four terminals are set to be movable by a spring, it is only necessary that four terminals contact normally when pressed against an electrical component, but even one of them has poor contact or the movable part is insulated. If it is defective, there is a risk that the measurement will be impossible, and conversely, there will be a risk of erroneous measurement as if it were normal.

An object of the present invention is to separate the direct connection between the supply terminal and the measurement terminal, which causes the above-described erroneous measurement, and to eliminate the movable portion between the terminals so as to prevent a contact failure and an insulation failure from occurring. It is an object of the present invention to provide a conductive contactor that reliably contacts a component.

[0004]

In order to achieve the above object, according to a first aspect of the present invention, a contact surface in which a first contact and a second contact are fixed and fixed at one end, and the contact surface is an electric component A spring or other resilient force applying means provided to resiliently contact a load or a measurement object, and the other ends of the first contact and the second contact are independently connected to a power supply or a measuring instrument. And a distribution cable provided as described above.

According to a second aspect of the present invention, a contact surface provided at one end of the first contactor and a second contact surface fixed at one end to the contact surface are integrated.
A contact, a spring or other resilient force applying means provided so that the contact surface resiliently contacts a load such as an electric component or a measurement object, and the first contact and the second contact are respectively independent of each other. And a distribution cable provided to be connected to a power supply or a measuring instrument.

According to a third aspect of the present invention, a cylindrical first contact having one end provided with a contact surface is integrated with the first contact in an insulating manner and fixed at one end to the back surface of the contact surface. The second contact, a spring or other resilient force applying means provided on the periphery of the first contact, and independently connected to the first contact and the second contact, respectively, and connected to a power supply or a measuring instrument. And a connected wiring cable.

According to a fourth aspect of the present invention, the direct connection between the supply terminal and the measurement terminal is separated, and a pair of conductive contactors is used. Each of the contact surfaces is connected to an electric component or the like via a spring or other elastic force applying means. And a conductive contactor provided in such a manner as to be in contact with the load or the object to be measured and to be capable of conducting or electrically measuring by the four-terminal method.

[0008]

According to the first aspect of the present invention, one end of the first contact and the second contact is fixed at the contact surface and integrated to be able to resiliently contact the load as an electric component or the object to be measured. The one contact surely contacts the electric component, and can be used as a pair in the four-terminal method. In addition, since the form is not limited, when the contact surface is a single plane and the first contact and the second contact are connected and fixed thereto, or the second contact is inserted into the first contact. May be provided. The two contacts have no separate movable parts and are integrated so that they come into contact with the electrical components as conductive contactors by means of a spring or other resilient force imparting means. Can be connected to

If the position is as close as possible to the electric component, unnecessary impedance is not generated at this portion, and accurate measurement can be performed. When a constant voltage power supply is used as a power supply, the constant voltage power supply must be operated so that the voltage of the measurement terminal is always constant. Therefore, two wires from the measuring terminal to the contact were wired,
An accurate voltage is applied to the load, or the voltage between both ends of the object to be measured is accurately measured, and the value is fed back to the power supply device. Therefore, since only a small current flows through the measurement terminal, the voltage drop can be ignored and the operation is performed so that the voltage is always constant.

In the second invention, a contact surface is provided at one end of the first contact, and one end of the second contact is fixed to and integrated with the contact, so that the first contact comes into resilient contact with a load such as an electric component or an object to be measured. There was only one contact surface, and there was no risk of poor contact. In the third aspect, the second contact is inserted into and integrated with the cylindrical portion of the first contact, so that the electric component can be reliably contacted by contact with the contact surface. A spring or other resilient force applying means provided on the peripheral edge of the first contactor ensures that contact with the measurement symmetry is performed.

[0011] Each contact is provided with a wiring cable that is independently connected and connected to a power supply or a measuring instrument, so that connection to the power supply or the measuring instrument is also ensured, and precise energization and measurement are possible. . In the fourth invention, the direct connection between the supply terminal and the measurement terminal is separated, and a pair of conductive contactors are used. Each contact surface is connected to an electric component or other load or a load via a spring or other elasticity applying means. By contacting the object to be measured, current or electric measurement by the four-terminal method can be realized.

It was done. By providing a contact surface as a conductive contactor and fixing and integrating the first contact and the second contact, there was no contact failure and the accuracy was improved.
