(54) DEVICE FOR ADJUSTING RADIO DETAILS TO THE MEASURING UNIT

I

The invention relates to radio. electronics, in particular, to devices for connecting radio components to the measuring unit, and is intended for use in devices for measuring electrical parameters of flat ceramic capacitors.

According to the main auth. A device for connecting radio components is known to C, comprising a housing with a central opening for resetting radio components, radially arranged contacts with cylindrical springs, a driving cam and stop rollers covered by said springs, the ends of which are fixed on each pair of contacts 1.

However, the known device does not provide reliable contact with a controlled product.

The purpose of the invention is to increase the reliability of contact.

The goal is achieved by the fact that in the device for connecting

radio components, comprising a housing with a central opening for resetting radio components, radially arranged contacts with cylindrical springs, a driving cam and thrust rollers covered by said springs, the ends of which are fixed to each pair of contacts, radially placed contacts are shifted relative to the center of the radio carrier holder, and the contacts contacting Radio components are electrically connected in pairs with diametrically opposed contact pads.

FIG. t shows the proposed

15 device; in fig. 2 - pin connection diagram.

A device for connecting radio components to the measuring unit includes a housing 1 with a central stand 2. Four slots 3 are located in the slots of the housing 1, pressed by a lid 4. On the sliders 3, insulating holders 5 are fixed for contacts 6j, the scrambled ends of which are in contact with the end contact surfaces radio components. Contacts 6 are electrically connected in pairs and are offset from the center of the contact zone. The sliders 3 are provided with stop rollers 7 interacting with a driving cam 8 fixed on a ring 9 having a ball bearing and a lever 10 for connecting to the mechanism controlling the cam 8. The insulating holders 5, bearing contacts 6, are spring-loaded so that the coiled cylindrical springs 11, covering the rollers 12 and attached at their ends to a pair of contacts 6, uniformly pressing each contact 6 to the radio component, regardless of the removal of the contact surfaces of the radio component from the contacts. The device is attached to the base13 with a nut I

The device works as follows.

When the lever 10 is rotated clockwise, the cam 8 acts on the thrust rollers 7 and retracts the slide blocks 3 with contacts 6 from the center of the hole 2. A radio component is installed in the free zone with the contacts retracted. The latter can be held in this position, for example, by a suction cup.

When the cam B is rotated in the opposite direction (the lever 10 is turned counterclockwise), the sliders 3 are released and, under the action of the springs 11, the contacts 6 are moved towards the center. Since the springs 11 held by the rollers 12 are fixed to the ends on the pair of contacts 6, their movement does not depend on each other, thereby ensuring reliable contact with the contact surfaces of the radio component. After the contacts 6 have been completely pressed to the contact surfaces of the radio component, the vacuum suction device departs.

After the measurement, the contacts 6 are retracted from, and the radio component, which is not held in any way, falls through the opening 2 into the receiver.
