Abstract

Abstract A plurality of probe wires are held by a probe supporter having a substantially rectangular cross-section. First, second and third side walls of the supporter, support the probe wires in a manner wherein they are arranged at predetermined intervals in an essentially parallel relationship with each other. The probe wires respectively extend from the first side wall to the second side wall by way of the third side wall. When testing an electronic-device, the third side wall faces a main surface of the device. The third side wall has a groove extending in a direction parallel with the main surface of at least one of the first and second sides wall. Each of the probe wires crosses the groove in a direction perpendicular to the direction along which the groove extends. The portions of the wires which cross the groove are pressed against the tested terminals.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 88 words
A multi-point test probe assembly comprising: a body member with a groove provided in one surface thereof and; a plurality of wires disposed on said body, each of said plurality of wires extending across said groove in a transverse manner and in spaced apart parallel relationship with one another so that portions of said plurality of wires extend across said groove, said portions of said plurality of wires which extend across said groove being arranged to be brought into contact with contacts of an electronic device under test.
Claim 2
Dependent Claim 88 words
A multi-point test probe assembly comprising: a body member with a groove provided in one surface thereof and; a plurality of wires disposed on said body, each of said plurality of wires extending across said groove in a transverse manner and in spaced apart parallel relationship with one another so that portions of said plurality of wires extend across said groove, said portions of said plurality of wires which extend across said groove being arranged to be brought into contact with contacts of an electronic device under test.
Claim 3
Dependent Claim 36 words
A multi-point test probe assembly as claimed in claim 1, further comprising a first tensioning member provided in said groove so as to exert a force on the portions of said wires which cross said groove.
Claim 4
Dependent Claim 32 words
A multi-point test probe assembly as claimed in claim 2, wherein said first tensioning member is a hollow tube of elastic material, said hollow tube being filled with a pressurized viscous fluid.
Claim 5
Dependent Claim 16 words
A multi-point test probe assembly as claimed in claim 3, said viscous fluid is silicone oil.
Claim 6
Dependent Claim 52 words
A multi-point test probe assembly as claimed in claim 2, further comprising second and third tensioning members each of which is made of elastic material, said second and third tensioning members being respectively provided in first and second side walls of said body in a manner to be parallel with said groove.
Claim 7
Dependent Claim 28 words
A multi-point test probe assembly as claimed in claim 5, further comprising a fourth tensioning member provided between the bottom of said groove and said first tensioning member.
Claim 8
Dependent Claim 42 words
A multi-point probe assembly as claimed in claim 1, further comprising a tensioning member for exerting a force on said plurality of wires, said tensioning member being provided on a surface of said body member which is opposed to said grooved surface.
Claim 9
Dependent Claim 33 words
A multi-point test probe assembly as claimed in claim 7, wherein each of said plurality of wires has a plating layer along a limited length of the portion which extends across said groove.
Claim 10
Dependent Claim 24 words
A multi-point test probe assembly as claimed in claim 8, wherein said plating layer is an abrasion resistance layer consisting of gold and cobalt.
Claim 11
Dependent Claim 53 words
A multi-point test probe assembly as claimed in claim 7, further comprising a plurality of balls, said balls each having a through-hole through which one of said plurality of wires is inserted, each of said balls supported in the shadow of said groove and being held in place by an elastic resin adhesive.
Claim 12
Dependent Claim 24 words
A multi-point test probe assembly as claimed in claim 10, further comprising means for biasing said balls in a direction away from said groove.
Claim 13
Dependent Claim 60 words
A multi-point test probe assembly as claimed in claim 7, further comprising a plurality of rods, each of said rods having a through-hole through which one of said plurality of wires is inserted, said rods being disposed on the portions of the wires which cross said groove, one end of each rod being held in place by an elastic adhesive.
Claim 14
Dependent Claim 31 words
A multi-point test probe assembly as claimed in claim 12, wherein said one end of each of said rods is received in a recess provided in a wall of said groove.
