Description

The invention relates to electrical connection devices.

FIG. Figure 1 shows the connector in the articulated position, with a longitudinal section through the 5th section; in fig. 2 shows section A-A in FIG. one; in FIG. 3 - spring contact element sockets and pin plugs in the articulated position.,

The electrical connector consists of two detachable parts: plug 1 and socket 2.

Fork 1 is a rectangular cross section of insulated material, into which pins 3 are inserted, made, for example, by stamping from brass and then coated with precious metals. The pins 3 in the fork 1 are locked 20 with the strap 4 made of insulating material and have a tail part 5 for soldering connection

, wires and the nose part 6, consisting of a bevel 7 and 25 flat parts 8 opposite it to it with ledges 9 and 10.

The socket 2 of the electrical connector is made in the form of a rectangular case of insulating material hell with spring contact elements 11 inserted into it, made, for example, of bronze and then coated with precious metals. Spring contact elements 11 are included in the sockets 12 of the socket 2 due to the elastic properties of the material - bronze.

Spring pin 11

made of two petals 13 and 14 connected by a U-shaped bridge 15 Petal 13 has a wave-shaped part 16, a bent end 17 and a groove 18. Petal 14 has a wave-shaped part 19 and a straight part 20 bent at an angle of more than 90 °.

The articulation of the detachable parts of the connector as follows.

Pin contact elements 3 are locked in a fork 1 with a strap 4,

The plate 4 enables the “swimming” of the pin contact elements' 3 in the plug 1 within 0.1 mm in the axial direction and 10.05 mm in the transverse direction. Floating the pins 3 is necessary to prevent them from incorrectly articulating and, therefore, for more reliable articulation. To make the connection, the pin contact elements 3 of the plug 1 are inserted into the sockets 12 of the socket 2. In this case, contact-friction occurs. surfaces of floating rigid pin contact elements 3 and spring contact elements 11, sufficient for removal of oxide films from them. The contact elements 3 and 11 are articulated by contacting at least two points, which ensures high reliability of the electrical connector during adjustment work, during which multiple articulation-dissection is performed. After the adjustment is completed, solder connection of the contact elements 3 and 11 is made. Spring tongue with groove 18 is soldered to the nasal parts with ledges 9 and 10 so that the nose parts with ledges 9 and 10 enter into

. grooves 18. This form of tongues with grooves 18 greatly facilitates soldering. Bevel thickenings 7 of the nose parts 6 of the pin contact elements 3 during soldering prevent the solder from spreading over the surface of the pin contact elements 3 due to the fact that the thickenings make the contact elements more massive, therefore, more heating of the metal is necessary. In addition, the bulges create a mechanical barrier to the spreading of the solder. The connector is operated in a sealed state.
