Изобретение относитс к радиоэлектронике и может быть использовано дл соединени с выходными кон тактны т площадка ми преимущественно теплопроводных печатных плат, электроэлементы которых требуют отвода тепла к внешнему теплообменнику.The invention relates to radio electronics and can be used to connect to the output pins with areas of predominantly heat-conducting printed circuit boards, the electrical elements of which require the removal of heat to an external heat exchanger.

Известен электрический соединитель , содержащий корпус, упругие контакты 1 .Known electrical connector, comprising a housing, elastic contacts 1.

Недостатком данного узла вл етс невозможность отвода тепла от элементов, расположенных на плате, и большое усилие расстыковки и стыковки .The disadvantage of this node is the impossibility of heat removal from the elements located on the board, and a large disconnecting and docking force.

Известен также электрический соединитель , содержащий корпус,в полости которого расположены контакты,выполненные из упругих пластин,хвостова часть которых жестко соединена с корпусом, узел разжима -контактов, установленный между свободны концам контактов и рзанмодействукщий с ними 2 J.An electrical connector is also known, comprising a housing, in the cavity of which contacts are made of elastic plates, the tails of which are rigidly connected to the housing, an unclamping node of contacts, which is installed between the free ends of the contacts and 2 J.

Недостаткой указанной конструкции вл етс невозможность отвода тепла от элементов, установленных на плате .The disadvantage of this design is the impossibility of heat removal from the elements installed on the board.

Claims

X figure 2 - connector, side view; on fig.Z - connector without board, cross-section; on (} ig.4 - connector with board, transverse section; figure 5 - connector coupled to the board; cross section. The electric connector contains a housing 1 consisting of individual sections 2 made of a dielectric. Each section contains heat-conducting sleeves. 3 with two contacts 5 attached to their side opposite surfaces 4. The surfaces of the sleeves 3 are flat and an electrically insulating coating 6 is applied to them. The bent ends 7 of the contacting part 8 of contact 5 rest on the inner wall of the housing 1 of the connector. 9 and the contacting part 8 are connected by a heat-removing bus 10, for example, from a set of strips of copper foil. Bus 10 is attached to contacts 5 by means of a holder 11. Separate sections 2 of case 1 are assembled in the heat supply zone of the heat pipe 12, fixed between a protrusion and a hollow 13. In the holes 14 of section 2 of case 1, there is a cam rod 15, which has a slot 16 at the end. Section 2 of case 1 is fixed on the heat pipe 12 with a nut 17. Zone I8 of heat removal Heat pipe 12 is located outside the case 1 connector Each section 2 has a slot 19 The slots form, when assembling the housing 1 of the connector, a common longitudinal groove 2 for mounting the printed circuit board 21 to contact pads 22. The connector works as follows. By turning the cam rod 15, the contacting parts 8 of the contacts 5 are unclenched. At the same time, between the parts 8 of the contacts 5, the largest gap is formed, allowing the installation of the printed circuit board 21 to the connector groove 20. Then, by turning the cam rod 15 to 180 of the part 8 of the contacts 5, the spring bent parts 7 of the contacts 5 are pressed to the contact pads 22 of the printed circuit 21, creating reliable electrical and thermal contact. The elasticity of the contacts of the tagging outlet shi1 {10 is not broken, since the 4 bus 10 is made of strips of copper foil. Thus, the main heat flux from the electrical elements installed on the heat-conducting printed circuit board 21 is transmitted to the contact pads 22 located on the two edges of the board, then on the part 8 of the contacts 5 and through the heat sink pins 10 on the part 9 of the contacts 5. Then the heat flux passes through the sleeves 3 and gets to the heat pipe 12 and to the external heat exchanger, with which zone 18 is joined. Combining the functions of electrical and heat transfer in one element is expedient, as it allows to significantly simplify the design of radio electronic th device requiring cooling. There is no need to use various special devices that provide heat transfer in a conductive way. Claims of the Invention An electrical connector comprising a housing, B cavities of which are contacts made of i, elastic plates, the tail part of which is rigidly connected to the housing, a contact opening assembly installed between the free ends of the contacts and the interaction with them, characterized in that in order to increase reliability, it is equipped with a heat pipe and heat-removing tires, the heat pipe is installed along the longitudinal axis of the housing located between the tail portions of the contacts and is rigidly connected with them, And this part of the tepov tube leaves the casing, and the heat-removing tires are made of flexible material and connect the tail and contact parts of the contact.
