Abstract

PURPOSE:To surely bring the probe into contact with a lead terminal by constituting the probe so that it can be brought into contact with the lead terminal of a body to be inspected from both directions of the horizontal direction and the vertical direction. CONSTITUTION:Contact pins 5, 6 are projected to the diagonal upper part at a necessary interval from a horizontal base part 5', and these base part 5' and pins 5, 6 are constituted of a member having elasticity. Also, the pins 5, 6 are not brought into contact with each other. When a body to be inspected 1 reaches a measuring position C, a free end part 5a of the pin 5 comes into contact with a lead terminal 3 of the body to be inspected 1, and while the pin 5 is holding a state that its end part 5a comes into contact with the terminal 3, a deflection is generated in the base part 5' of the pin 5, and a free end 6a of the pin 6 comes into contact with the terminal 3. In such a way, the probe can be brought into contact with the lead terminal of the body to be inspected from both directions of the horizontal direction and the vertical directions with respect to be working direction.

(Function) The multi-contact probe according to the present invention is configured such that at least one terminal contacts each of the vertical and horizontal directions of the test object, and the terminals are configured so that they do not contact each other. A required gap is formed between each terminal, and since the terminals are made of an elastic material, the terminals that contact in the horizontal direction with respect to the direction of action of the test object contact the lead terminals of the test object first. The contact terminal flexes while the free end of the terminal maintains contact with the lead terminal, so that the flexure causes the other terminal, which is integrally provided with a predetermined gap with the terminal, to flex. Since the terminals also make contact in the vertical direction of the test object, both contact terminals will surely contact the lead terminals of the test object, and the tester and lead terminals will be electrically connected and the characteristics of the test object will be tested.

When the test is finished, the free ends 5a, 6a of both contact bottles 5.6 are freed from the load of the test object holding part and are separated from the lead terminals 3 of the test object 1, and both contact bottles 5.6 move away from their horizontal bases 5. It returns to its original position due to the elasticity of . Thereafter, the specimen 1 falls under its own weight or is forced to fall to the classification section in the next step, and another specimen is supplied to the measurement position C, and the same operation as described above is repeated.

In this embodiment, as described above, both contact pins 5.6
Both of the free ends 5a and 6a can be reliably brought into contact with the lead terminal 3 of the subject 1, and for example, the free ends 5a, 6a can be brought into contact in a horizontal direction with respect to the direction of action of the subject 1. Lead terminal 3 to free end 5a of pin 5
If a foreign object is present on the top, the contact pins 5, 6 will move against the horizontal base 5'.
Since it is composed of one elastic body through the
The free end 6a of the contact pin 6, which contacts the lead terminal 3 in a direction perpendicular to the acting direction of the contact pin 6, can contact the lead terminal 3 strongly by the size of the foreign object. this is,
Similarly, if there is a foreign object on the lead terminal 3 that contacts the free end 6a, the free end 5a can contact the lead terminal 3 as strongly as the size of the foreign object. If there is a foreign object on the lead terminals 3 for both of which 5a and 6a are in contact, they will not return to their original positions because the free ends 5a and 6a are made of a piece of elastic material such as tungsten or beryllium copper. The force acting on the lead terminal 3 causes the foreign matter to break down and come into contact with the lead terminal 3, thus making it possible to perform highly reliable measurements.
