SU758329A1 - Device for connecting printed-circuit board to radio electronic unit - Google Patents

Description

The invention relates to computing and electronic equipment, namely to the verification of electronic components with retractable printed circuit boards.

A device for connecting an extended printed circuit board to an electronic unit is known, which comprises a U-shaped case with transitional connectors placed on it, printed circuit guides and a printed circuit extraction unit £}.

However, in this device the removal of printed circuit boards connected to the unit and the removal of the device itself from the unit occur manually, which significantly complicates operation, as it leads to distortions of the connectors of printed circuit boards or transitional connectors of the device in the unit and to the device failure. '20

The purpose of the invention is the convenience of operating the device for connecting a printed circuit board to an electronic unit.

For this purpose, in the proposed device, comprising an U-shaped case with transitional connectors placed on it, guides for a printed circuit board and a unit for extracting a printed circuit board, is achieved by the fact that node 30

PCB extraction is made in the form of pairs of rods and spring-loaded latches installed in pairs in the bases of the housing body, installed with the possibility of alternate interaction with each pair of rods, one pair of rods being spring-loaded relative to the housing.

FIG. 1 shows the proposed device, a general view; in fig. 2 is a view along arrow A in FIG. one; in FIG. SUBSTITUTION BB in FIG. one; in fig. 4 is a view along arrow B in FIG. one; on Fig.5Under when removing the printed 6 - section G-Y on 7 - view on the arrow

when retrieving it from a block, general view.

The device contains a U-shaped case 1, on which are placed the transitional connectors 2 and 3, the movable bar 4, the guides 5 for the printed circuit board, rods b, spring-loaded relative to the case, springs 7, rests on the case for printed-circuit boards 8, rods rigidly fixed in the case 9, spring-loaded latches 10 placed in the guides 5, spring 10 of the latches. In rods 6 and 9 are made

notches 12, and the latch 10 is equipped with protrusions 13, which alternately go into the notches of the rods 6 or 9. In the guides 5 there are grooves 14 for moving the printed circuit board 15.

The device works as follows.

The device is inserted into the unit instead of the removed printed circuit board so that connector 2 would be connected with the connector installed in the unit. The printed circuit board 15 removed from the unit is pushed along the grooves 14 of the guides 5 to the joint; a printed circuit connector with an adapter connector 3. Moving along the guides 5, the printed circuit board 15 installs the latches 10. At the same time, the projections 13 of the latches 10 enter into the notches 12 rods b, printed the board is electrically connected to the unit. Repair or adjustment of the board.

To remove the printed circuit board 15, it is necessary to compress the case 1 and the strip 4.

Since the rods 6 are fixed with latches. 10 relative to the guides 5, the housing 1 begins to move along the rod 9 relative to the guides

5. Placed on the case, the lugs 8 carry along the printed circuit board 15, which leads to the dismemberment of the connector of the printed circuit board with an adapter connector

3. The circuit board is removed from the device. After the removal of the PCB latch 10 under the action. Springs

11 are extended, as a result of this, the protrusions 13 of the latches 10 extend beyond the recesses 12 of the rods 6 and enter the recesses

12 rods 9. Plank 4 under the action of the springs 7 occupies the initial position. When re-compressing the strap 4 and the housing 1, the rods 6 extend beyond the limits of the guides 5, abut their ends against the protrusions of the block and remove the device from the block.

Claims (1)

Claim A device for connecting a printed circuit board to an electronic unit containing a U-shaped case with transitional connectors placed on it, guides for a printed circuit board and a printed circuit extraction unit, characterized in that, for ease of operation, the extraction assembly of a printed circuit board is in the form of pairwise placed in the bases of the body of the rods and spring-loaded latches installed with the possibility of alternate interaction with each pair of rods, with one pair of rods springing relative to the body.
