SU1582234A1 - Contact pair for electric connectors - Google Patents

Abstract

The invention relates to radio engineering. The aim of the invention is to increase the vibration and impact resistance and decrease the contact resistance. The contact pair for electrical connectors comprises friction contacts 2 and 7 placed in electrically insulating bodies 1 and 6. Contact 7 is made in the form of a flat elastic plate having two or more arcuate protrusions 8 in the form of gentle waves of the same height. The ends 9 and 11 of the contact 7 are fixed in the housing 6. The contact 2 has an end 5 bent in the form of a half-wave. The fixing of the ends of the contact 7, the presence of three or more contact areas and additional pressing of the contact 7 with the short and hard curved end 5 of contact 2 ensures the achievement of the purpose of the invention. 1 il.

The invention relates to radio electronics and can be used to make detachable electrical contact of printed circuit boards.

The purpose of the invention is to increase the vibration and impact resistance and reduce the contact resistance.

The drawing shows a contact pad.

Contact pair consists of two cha, stey - pin and socket. The pin consists of an insulating body 1 and a contact element 2. The contact element 2 is made of an elastic metal tape and has a U-shape. One branch of the contact element 2 is located in the opening 3 of the housing, and the other branch is part of the length of the hole in the groove 4, tightly encloses the housing 1, and has a bent end 50. The socket consists of an insulating casing 6 and the contact element 7 made of elastic metal tape, has at least two protrusions 8 of the same height and bent 180 ° to the side opposite to the connection, the upper part (end) 9 "The ends of the TakTHoro element 7 are rigidly fixed as follows: the end 9 is installed in the hole 10, and the end of 11 you blunt 12 is supported on the housing 6,

The end 11 of the contact element 7 is soldered to the printed circuit board 13 by soldering, and the end 14 of the contact element 1 is fixed in the holes of the printed circuit board 15 or attached to the installation wires 16.

Contact pair works as follows.

When articulating the pin with the socket, the protrusions 8 of the contact element 7 are successively compressed, then the bent end 5 of the contact

element 2 interacts with the bent upper part (end) 9 of the contact 7. Due to the small length, the bent end 5 has greater rigidity and provides a large pressing force, In combination with the presence of three or more sections of electrical contact, rigid fixing of the ends of the contact element 7 and tight fit in the housing 1 of the contact element 2, the object of the invention is achieved;

Claims (1)

15 claims A contact pair for electrical connectors consisting of two parts, a pin and a socket, each of which contains an insulating body with a contact element, characterized in that, in order to increase vibration and shock resistance and reduce contact resistance, the pin body is made the through-hole, the contact element of the pin is made of an elastic U-shaped metal tape, one branch of the contact element is located in the indicated opening of the housing, and the other branch is part of the length tightly enclosing the housing, while the horse it is bent, the socket contact member made of elastic metal strip at least 0 with two protrusions of the same height and bent 180 ° to the side opposite to the connection, with the ends of the contact element of the socket rigidly fixed in the case, while the protrusions of the contact element of the socket interact with a part of the contact element pin tightly surrounding the case element of the socket interacts with the bent end of the contact element pin,
