Description

The invention relates to multi-cycle electrical connectors used in electronic engineering, instrumentation, automation systems, computer technology, in particular in the field of input control and preparation for mounting integrated circuits.

. The aim of the invention is to increase reliability, reduce contact wear, expand the scope of application and technological capabilities due to the formation of leads.

Fig. 1 shows a contact device, in the working state is a front view in Fig. 2, node I. in Fig. 1 {when the chip is loaded, the levers are open) J in Fig. 3 - the same, in the working state 5 {contact device (the levers are closed) j in figure 4 - the same, before unloading the microcircuit (the levers are open) „

The contact device contains a latch 1, made in the form of a dielectric plate, an eccentric 2 with a handle, spring-loaded levers 3 with dielectric heads 4, made with two ledges and the possibility of bending the pins 5 of the microcircuit and clamping them to the contact elements 6. The levers 3 are mounted on the axes 7 and clamped to the eccentric 2 by means of springs 8, one ends of which are fixed on the levers 3, and others - on the basis of the NII 9.

The device works as follows.

After installing the microcircuit into the latch of the fixture 1 (Fig. 2), under the action of the eccentric 2 with the handle, the levers 3 turn and the dielectric heads 4 are fed to the microcircuit housings and outputs 5 (Figures 1 and 3). The upper ledges of the heads 4 hold the microsg: it is from lifting, and the lower ones bend the pins 5 of the microcircuits in their middle part, while the free ends of the pins 5 abut against the contact elements 6 and, bending, press against them. When the eccentric 2 with the handle returns to its original (vertical) state, under the action of the springs 8, the levers 3 are rotated to the initial state (Fig. 4). Nikroskheiz contact us0

In the known contact devices, stationary spring elements are used, which experience loads during each work cycle, which leads to their wear and reduces the reliability of the contact devices. In the proposed contact device, spring elements are the spring elements, i.e. In this case, the number of cycles of operation of the spring element is very small — one, two or three cycles, which leads to an increase in the reliability of operation of the contact device. In addition, when fixing the microcircuit in the proposed contact device, the bending of the microcircuit pins is carried out, which makes it possible to use it as a device for forming the microcircuit pins.
