Description

(54) Two-piece miniature connector

The invention of the miniature two-piece connector falls within the field of computer technology. It solves the problem of components for solderless assembly on printed circuit boards.

The miniature two-piece connector is made of conductive material and is equipped with multi-segment flexible contacts for non-solderable detachable connection to the component outlet and to the heads for conductive connection with wire conductors. One part of the mini connector is intended to be pressed into a through hole from one side and the other part to the same hole from the other side of the board. Both of these parts are conductively connected by a through-hole.

The application of the invention can be envisaged in the field of computer technology in the solderless assembly of components on printed circuit boards.

The invention is best characterized by the attached figure.

BACKGROUND OF THE INVENTION The present invention relates to a miniature two-piece connector for insertion into a forged PCB bore, in particular for computer-aided prototype devices, and to address an increase in assembly density while increasing versatility while maintaining the possibility of accurately defining high-frequency transfer characteristics.

According to known solutions, miniature connectors are provided. as a rivet of conductive material having an internal spring contact disposed in a body adapted to its outer profile, i.e., axial or radial edges or grooves for reliably pressing into the printed circuit board, the shape of these edges or grooves can be adapted such that mediates the formation of a reliable gas-tight joint between the metallization of the forged hole and the mini-connector pressed into the hole. The head of the mini connector, i.e. the side 'opposite to the side of the insert, is adapted to be shaped' to connect a wire conductor, such as a wrapping tip, or a welding pad.

The disadvantage of these embodiments is that it is not possible to connect the wire conductor as well as to assemble components from both sides of the board. If precise definitions of the high-frequency joint characteristics, especially characteristic impedance, are needed, the one-sided mini-connector cannot maintain the exact wire spacing above the board in close proximity to the connector for different board thicknesses.

These drawbacks are overcome by the miniature two-piece connector according to the invention, for insertion into a through hole of a printed circuit board, of conductive material, for example bronze, with multi-segment elastic contacts for non-solderable detachable connection with the component outlet on one or both parts; adapted for a conductive connection to a wire conductor, for example by soldering, characterized in that one part of the miniature connector is pressed into the forged hole of the printed circuit board from one side thereof and the other part is pressed into the same hole from the other side and both parts of the miniature connector they are conductively connected through a forged opening.

The miniature connector according to the invention is also advantageous in that the heads of the miniature connector are both in the shape of a smooth soldering ring or a crown for a cutting joint, or that the heads of the miniature connector are of different shapes, for example one

Claims (7)

SUBJECT 1. Miniature connector, two-piece, intended for insertion into a through hole of printed circuit board, made of conductive material, for example bronze, with multi-segment elastic contacts for non-soldering dismountable connection with component outlet on one or both parts and heads on both heads. for brazing and a second crown shape for the cutting joint. It is also possible to design a two-piece miniature connector arranged such that the body of the miniature connector has grooves or grooves on its circumference for fixing in the hole or for forming a gas-tight joint. The invention also relates to another embodiment of a two-piece miniature connector adapted to each of which is made of a different material, for example one of bronze and the other of brass. Another modification is that in the miniature connector of a two-piece one or both parts are surface plated, for example by gilding. A further arrangement of the miniature two-part connector is that one or both parts of the miniature connector are provided with a key, for example in the form of a projection for oriented placement in the printed circuit board. The attached drawing shows a possible embodiment of the miniature connector 2. The miniature connector 2 is pressed into the printed circuit board 4, with a forged hole 3. The heads 6 can be made according to the connection technology, for example with a soldering or welding surface. The heads 6 may be of the same but also different types, for example one for soldering and the other for welding. The segmental spring contact 7 may be provided on one or both parts of the miniature connector 2. The body of the miniature connector 2 may be provided with grooves or grooves 8 on the periphery for fixing in the hole and for forming a gas-tight conductive connection. The miniature connector 2 may be made entirely of the same material, such as bronze, or each part may be of a different material, such as a berylbronge elastic segment and a brass-free segment. For better mechanical properties, the miniature connector 2 can be heat treated or molded, for example by quenching, forming, artificial aging. In order to reduce the transient resistance, it is advantageous to surface the miniature connector 2, for example by gold plating. If it is necessary to orient the miniature connector 2 or one of its parts, it is suitable to provide it with a key 9, for example in the form of a protrusion. The miniature two-part connector according to the invention is particularly advantageous for mounting and interconnecting components on boards in complex, high-density devices.
