Abstract

The invention relates to radio engineering. The purpose of the invention is to increase contact reliability and measurement performance. The findings of the device 9, mounted on the conveyor 10, come into contact with the elastic current collector (T) 7. T7 made in the form of combs. The plates of one comb are placed between the plates of the other. Under the action of force, the contact holders 4 with T7 rotate, continuing contact with the device until the gap between T7 becomes equal to the output diameter of the device 9. After that, the contact holders 4 return to their original position. 3 il. (L figure 1

Description

one

The invention relates to radio engineering and can be used in control devices for connecting semiconductor devices with rigid axial terminals.

The purpose of the invention is to increase contact reliability and measurement performance.

FIG. 1 shows a contact device, a top view, FIG. 2, a cut A-A in FIG. one; in fig. 3 - view B on fig2.

The contact device comprises an insulating body 1 with pressurized 2, made in the form of stepped protrusions with a rounded step 3, contact holders 4 equipped with holes 5 through which the projections 3 of the guides 2 protrude. Contact holders 4 are made of a dielectric with conductive tracks 6, which are fixed to the current collectors 7, made in the form located in the same plane with a certain pitch of elastic strips or wires.

The contactors 4 are spring-loaded by the elastic element 8, and the elastic strips of each current collector are directed one towards the other, are inserted between them and under the action of the elastic element 8 are pressed to the housing 1. Semiconductor devices 9 are placed on the conveyor Y.

The device works as follows.

The semiconductor device 9 under test, attached to the conveyor 10, is passed into the hole of the insulating body 1 of the contact device. The connectors of the connecting device 9 come into contact with elastic strips (or wires) of the current collectors 7, which in the initial position are pressed against the body with a preliminary voltage. A certain force P from the conveyor 10 is applied to the semiconductor device 9, overcoming the resistance of the elastic elements 8,

providing the necessary contact force. The measurement starts.

Upon further advancement of the semiconductor device under the force P, the contact holders 4 hinged on the guides 2 rotate with the plate contacts 7, each of which remains pressed against the hard terminal of the measured semiconductor device with contact force until the gap 8 between the plate contacts will become equal to the diameter of the output (shown in thin lines, figure 2). The measurement is over. With further advancement of the semiconductor device, it passes the plate contacts. Contact holders 4 under the influence of elastic elements 8 return to their original position.

The continuous measurement cycle makes it possible to automate the measurement processes, resulting in improved performance, and the implementation of current collectors in the form of combs with plates increases the reliability of contact with the continuous movement of devices.
