Description

The invention relates to radio engineering and can be used for switching electrical circuits.

The purpose of the invention is to increase reliability in operation due to additional crimping of the plug socket.

At the same time, additional pressing of the contacts to the board is carried out regardless of the mechanical characteristics of the socket. The presence of a slope on the inner surface of the outlet ensures a uniform compression of the nozzle, while the reduction is carried out only in the final stage of articulation, which reduces the force of articulation-division in the remaining stages. The presence of the comb protects the contacts from accidental damage. Filling the inner space of the nozzle, the comb limits its deformation during compression of the outlet housing. In the articulated state, all the internal cavities of the connector are filled with material parts, tightly pressed to each other, which makes the design monolithic and ensures reliable operation in conditions of mechanical overload.

FIG. 1 shows the plug and socket of the electrical connector of the proposed design, front view; in fig. 2 is the same, section A-A in FIG. one; in fig. 3 - plug and socket of the proposed design in the articulated state.

The electrical connector consists of a plug containing a printed circuit board 1, placed and fixed in the connector 2 of the cable part of the connector ONP-ЖИ-8 3, made of an electrically insulating elastic material, and an outlet that contains the housing 4, in which the insulating comb 5 is located for the printed circuit board 1. The groove 6 is formed by two rows of teeth 7 of an insulating comb 5 placed on both sides in the shaft order. Between the teeth 7 are flat S-shaped spring contacts 8, each having two contact bends 9 and 10. One of the contact bends 9 enters the receiving groove 6 and contacts the printed circuit board 1, the other 10 you: walks into the gap between the outer surface comb 5 and the inner surface of the housing 4, which is made with a slope 11 equal to the slope 12 of the outer surface of the pipe 2. The teeth 7 of the comb 5 and the printed circuit board 1 are chamfered 13. The connecting wires 15 of the technological cable are soldered to the pads 14 of the flat spring contacts 8. The printed circuit board 1 has a double-sided pattern of printed conductors 16 connecting the contact pads 17 for desoldering the cable part of the ONP-JI-8 connector 3 and the platforms 18 for contacting the bends 9 of spring contacts 8. The board 1 is provided with metallized holes 19 for desoldering wires the main product harness, the holes 20 serve to mechanically fasten them to the board 1. The protrusion 21 of the printed circuit board 1 is designed to fix the fastening band of the main product harness, and also serves as a guide element and

0 joint with the socket.

When connecting the plug and socket of the electrical connector, the protrusion 21 of the printed circuit board 1 is inserted into the receiving groove 6, orienting the position of the socket relative to

with a fork in the same plane. Then the comb 5 enters the internal cavity of the nozzle 2, limiting the outlet displacement relative to the plug in two planes, and covers the board 1, providing the necessary direction of movement of the contacts 8 on the board 1.

0 Upon subsequent insertion, the contact bends of 9 spring contacts 8 come into electrical contact with the contact pads 18 of the board 1. With further insertion, the plug 2 of the plug fills the gap between the outer surface of the comb 5

5 and the inner surface of the socket housing 4 and with its inner surface exerts pressure on the contact bends 10 of the spring contacts 8, deforming them and further pressing the contacts 8 to the PCB 1. The elastic walls of the socket 2 are also deformed, especially in the middle part of the connector. However, upon subsequent insertion of the internal cavity of the housing 4 of the socket on a slope 11 compresses the nozzle 2 to complete alignment

5 with a slope of 12 and helps to preserve the force of pressing the contacts 8 to the board 1.
