Abstract

The invention relates to microelectronics, in particular, to the design of contact devices for large housing microassemblies with a large number of pin current outputs. The contact device comprises a base, in which there are rectangular openings for the passage of the shanks of the contacts and a rectangular recess for mounting the clamp, which is two identical frames installed one into the other with their possible movement relative to one another, and each frame includes located in a row rectangular holes, the walls of which serve to crimp the contacts passing through them, two jumpers for crimping the contacts under the additional pins and two wedge-shaped protrusions and on the outer side, an engine in the form of a rectangular frame mounted on the base and covering the clamp, with two tabs on the ends for reciprocating movement, having two recesses on the inner sides, serving as slots for the wedge-shaped protrusions of the clip, the panel, mounted on a base with rectangular openings, the walls of which serve as abutments for the upper ends of the contacts, and with a rectangular recess to limit the movement of the clip. A cover with round holes is fastened to the panel for passing the pins of the microassemblies, limiting the contacts from moving upwards. The contacts are made in the form of two elastic plates, one of which is movable — pressure, the other fixed — thrust.

Description

The invention relates to microelectronics, and in particular, to the design of contact devices for large housing microassemblies with a large number of pin outputs.

The purpose of the invention is to improve the reliability of contacting.

Figure 1 shows a contact device for housing microassemblies with forced crimping of contacts, general view; figure 2 is a section aa in figure 1, the position is open, figure.z is a section aa in figure 1, the position is closed; figure 4 - lock of two frames for forced crimping of contacts,

The proposed contact device comprises a base 1 (FIG. 1) with a rectangular recess 2 (FIG. 2) and with rectangular holes 3 for outputting the shanks of contacts, contacts 4, 5, a retainer 6 (FIG. 1) in the form of two frames 7 , each of which has rectangular holes 8 (Fig. 4), two jumpers 9, 10, two wedge-shaped protrusions 11 on the outer side of the frame 7 of the retainer 6 (Fig. 1) for interacting with the wedge-shaped recesses 12 of the slider 13 The slider 13 (figure 1) is made in the form of a rectangular frame with tabs 14 on the outer ends and four wedge-shaped corners lubes 12 on the inner side walls.

The slider 13 (FIG. 1) and the latch 6 are mounted on the base 1 so that the latch b is located inside the slider 13. The cover is made of two parts - the bottom 15 (FIG. 1) and the top 16. At the bottom of the cover 15 (FIG. 2) a rectangular recess 17 is made to limit the movement of the latch 6 and rectangular holes 1.8 for contacts, in the upper part of the cover 16 there are round holes. 19 for pins 20 ..

The device operates as follows: the slider 13 is in the open position (Fig. 1, 2), between the fixed 4 (Fig. 2) and the movable 5 contacts there are guaranteed clearances into which through the openings 19 in the upper part of the cover 16 freely slip along fixed contacts 4 are inserted pin conclusions 20 microassembly. By moving the slider 13 to the closed position, the frames 7 of the latch 6 are moved towards each other in the transverse direction with the help of the wedge-shaped protrusions 11 on them (Fig. 4) and a tight spring-loaded compression of the pin terminals between the movable 5 (Fig. 2) and fixed .4 contacts. The pressing of the contacts to the pin terminals located in the row is made by the walls of the rectangular holes 8 (Fig. 4). The contacts are pressed to the intermediate ground and additional pair pin terminals with jumpers 9, 10 of the frame 7. When the slider 13 is moved to the open position, the slider with its recesses 12 (Fig. Is installed against the wedge-shaped protrusions 11 (fmg, 4) of the frame 7, so way framework

get the opportunity to move apart, which happens under the action of the spring of the movable contacts 5. In this case, the contacts release pin leads from crimping and the microassembly is freely removed from the device. ..

A known block with forced crimping of contacts for integrated circuit housings, selected as a prototype, is unsuitable for microassembly housings with additional pin terminals located outside the series, since the construction does not provide for compression of intermediate pin terminals. .. /. . ...-. -.-

Formula A contact device for housing microassemblies with forced pin crimping, containing a base with rectangular holes designed to enter contact shanks, contacts, a latch, a cover, Moreover, in order to increase the reliability of contacting, it is equipped with a slider made in the form of a rectangular frame, on the outer ends of which are made tabs to provide longitudinal movement of the slider, and on the inner side walls four frames e wedge-shaped recesses, the said clamp is made in the form of two identical frames, each of which has rectangular holes, the walls of which are designed to crimp the contacts passing through them, two jumpers designed to crimp the contacts, two wedge-shaped protrusions on the outer side of the clamp designed to interact with the wedge-shaped recesses of the slider, the cover is made of two parts - the upper and lower, in the lower cover there is a rectangular recess and rectangular openings for acts, and in the upper part of the lid there are round openings for pin terminals, wherein said slider and lock are mounted on the base so that the lock is located in the inside of the slide frame.
