In an electrical connecting apparatus, a thermal deformation restriction member, a reinforcing plate, and an auxiliary member are made of materials having smaller thermal expansion coefficients in this order, and a wiring board supporting a probe assembly is coupled with the reinforcing plate. The auxiliary member has a void inside the coupling region with the reinforcing plate. The void receives the deformed part when the center portion of the wiring board is deformed toward the reinforcing plate. Thus, the thermal deformation restriction member, the reinforcing plate, and the auxiliary member function as a three-layer bimetal having a sandwich structure, and the thermal deformation of the wiring board is restricted effectively.

Electric connecting apparatus

An electrical connecting apparatus for use in electrical measurement of a device under test comprises a supporting member and a flat plate-like probe base plate. On one surface of the probe base plate are provided multiple probes abutting on electrical connecting terminals of the device under test undergoing an electrical test. Also, on the other surface of the probe base plate is formed a securing portion provided with a screw hole opened at the top portion. It further has a generally cylindrical spacer and a screw member passing through the spacer and whose tip end is screwed in the screw hole of the securing portion. As for the spacer, movement in the axial direction is restricted in relation to the supporting member by a restricting means. The spacer has a head portion whose underside is mounted on the other surface of the supporting member and a body portion communicating with the head portion at one end, arranged to pass through a through hole formed in the supporting member, and whose other end is arranged to abut on the top face of the securing portion.

Electrical connecting apparatus

An electrical connecting apparatus for use in an electrical inspection of a tester and a device under test. The electrical connecting apparatus is provided with a probe assembly to be tightened by tightening screw members toward the support member and having a wiring board interposed between itself and a support member. In order to prevent deformation of the probe board of the probe assembly due to tightening of the screw members, a spacer disposed to penetrate the wiring board is between the support member and probe board and penetrated by the screw members. Both end faces of the spacer are convex spherical surface.

The object of the present invention is to prevent an operator from touching electronic elements arranged on an upper surface of a probe assembly of an electrical connecting apparatus at the time of carrying the electrical connecting apparatus and to restrict bowing of the probe assembly caused by the temperature difference between the upper surface and the lower surface of the probe assembly. An electrical connecting apparatuscomprises a probe assembly having a plurality of contactorson a lower surface and a plurality of electronic elementsarranged on an upper surface, a coverarranged on the upper surface of the probe assembly so as to close a spacein which the electronic elements are arranged, and two grippersattached to the cover. Each gripperhas one endand the other end, has a region ranging from one end to the other end formed approximately in a U-shape, and is attached to a main body portionof the cover at both the ends.

A probe assembly for use in electrical measurement of a device under test. The probe assembly comprises a plate-like probe base plate with bending deformation produced in a free state without load, and a plurality of probes formed on one face of the probe base plate to project from the face. All the tips of the probes are positioned on the same plane parallel to an imaginary reference plane of the probe base plate.

Probe assembly, method of producing it and electrical connecting apparatus

A mounting apparatus that does not compromise the strength of a probe board. The apparatus comprises a probe board spaced from a support member by a spacer. A fixed portion with a female screw hole is mounted on one surface of the probe board. A male screw member is threaded into the screw hole for the purpose of tightening the support member to the probe board at a fixed distance defined by the length of the spacer. The probe board has a support plate. Pluralities of conductive paths penetrate the support plate. A wiring plate wherein wiring paths are connected to corresponding conductive paths, and whose one surface is fixed to the support plate. The other surface is provided with probes corresponding to the wiring paths. The fixed portion includes a female screw member at an area where no conductive paths are formed.

Probe board mounting apparatus

A wiring path of a circuit board has a first vertical path portion penetrating the circuit board at its outer edge in its thickness direction and connected to a connector on one surface, a second vertical path portion penetrating the circuit board in its thickness direction and connected to the electric coupler on the other surface, and a lateral path portion connecting both vertical portions, and the second vertical path portion is formed within an arrangement area (S) of a reinforcing plate. One connecting end portion (electric coupler side) of the wiring path of the circuit board is disposed within the arrangement area (S) of the reinforcing plate. On the other hand, the other connecting end portion (probe side) of the wiring path of the circuit board is disposed to be dispersed in an arrangement area (S) wider than the arrangement area (S) of the reinforcing plate.

A probe having a first and a second arm portion extending between first and second connecting portions connecting the first and second arm portions respectively at their front end portion and base end portion, and a needle point portion below the first connecting portion. At least one of the entire first and second arm portions or the upper or lower edge portions of the first and second arm portions are arcuate.
