As described above, the electrical component contact unit and the electrical component inspection unit using the electrical component contact unit according to the present invention are constructed and operated, so that a single type of contact unit can be used to convert a plurality of types of electrical components. It can be energized or inspected, has high versatility, can be formed into a small unit itself, can be produced in stock without waiting for manufacturing orders, has a short delivery time, and costs are low. This has the effect of being inexpensive.

Specifically, according to the electric component contact unit of the first aspect, when the unit main body is mounted on the contact portion of the electric component, the contact comes into contact with the contact pad of the electric component to be electrically connected. Therefore, it is possible to conduct electricity to the electric component via the contact pad and the contact. Electricity can be similarly applied to the contact parts having the same arrangement pattern of the contact pads of the electric parts by using the electric part contact unit having the same configuration.

According to the electric component contact unit of the second aspect, the unit main body is detachably formed on the contact portion by holding or opening the contact portion of the electric component. Can be easily attached to and detached from the contact portion of the electric component.

According to the third aspect of the present invention, the plurality of unit bodies are mounted on the long electrode member so as to be freely movable in the longitudinal direction, and a plurality of contact portions of the electrical component are provided. By connecting the contact to the contact pad, it is possible to conduct electricity to each connection portion. In addition, a single electrode member can simultaneously supply current to a plurality of contact units.

According to the electric part contact unit of the fourth aspect, the contact part of the flat part of the electric part is placed on the base member of the unit main body with the pressing member of the unit main body moved to the open position. The contact pad is placed in contact with the contact mounted on the base member, and then the pressing member is moved to a pressing position by driving means,
The contact portion of the electric component is sandwiched between the base member and the pressing member, so that the contact pad of the electric component and the contact are reliably electrically connected, and can be supplied to the energization thereafter.

According to the electric component contact unit of the present invention, the open position of the pressing member is a position retracted from a movement locus for attaching and detaching the electric component to and from the base member. Therefore, the electric component can be easily attached to and detached from the base member without being disturbed by the pressing member.

According to the electric component contact unit of the present invention, the driving means has a lever for moving the pressing member between the pressing position and the open position. The member can be moved between a pressing position and an opening position.

According to the electric component contact unit of the present invention, the contact is provided with an elastic force for elastically pressing the contact pad of the electric component. The contact pad is always elastically pressed, and the electrical connection between the two is reliably performed.

According to the electric component contact unit of the present invention, the elasticity given to the contact is the elasticity of the contact itself, and the long contact formed on the surface of the electrode member. Since the brush has at least one of the elasticity of the brush electrode electrically connected to the electrode and the elasticity of the elastic member for pressing the contact toward the contact pad of the electric component, the contact is given any elasticity. This ensures that the electric component is always elastically pressed against the contact pad.

According to the electric component contact unit of the ninth aspect, the contact is formed in the shape of a pin which comes into contact with the contact pad of the electric component with its tip, so that the pin-shaped contact is provided. Is securely connected to the contact pad of the electric component with its tip.

Further, according to the electric component inspection unit using the electric component contact unit according to the tenth aspect, the electric component is inspected using the electric component contact unit according to any one of the first to ninth aspects. Since the continuity inspection of the component is performed, the aging and continuity inspection of the electrical component can be performed in the same manner as when the electric component contact unit described in the above claims is energized.
