Description

Interposer assembly

The present invention relates to an interposer assembly.

In general, a board-to-board type connector is used to implement an electrical connection between an external device and a printed circuit board. This board-to-board connector electrically connects a printed circuit board with a flexible printed circuit board ("FPCB") containing a conductive pattern.

 Typical board-to-board connectors include a housing and a number of contacts (or also referred to as "terminals") fixedly disposed within the housing. Each contact is made of a conductive material, that is, a metal material. When coupling the FPCB and the connector, each conductive pattern of the FPCB contacts the corresponding contact of the connector so that the cable and the connector are electrically connected.

On the other hand, the other side of the connector is electrically connected to the printed circuit board constituting the external device, the FPCB and the printed circuit board is electrically connected through the connector.

As such, the connector used to electrically connect the FPCB to the printed circuit board has a problem that the volume of the electronic device to which the connector is mounted is increased because of the relatively large volume.

In addition, a large number of contacts must be arranged in the housing at a minute spacing, and in the event of deformation in any one of the contacts, full electrical connection between the FPCB and the printed circuit board cannot be expected.

Meanwhile, as one of external cables, an interposer that is directly mounted on a printed circuit board without using the above connector and electrically connected to a pattern of the printed circuit board has been developed and used.

The interposer has a plurality of terminals arranged in a matrix in the housing, and both ends of each terminal are exposed on the upper and lower surfaces of the housing. One end of the terminal exposed out of the housing is electrically connected to the conductive pattern of the printed circuit board, and the other end is electrically connected to an object to be electrically connected to the printed circuit board, for example a flexible circuit board (FPC) cable. Is connected.

When such an interposer is mounted on a printed circuit board, the interposer can be fixed without shaking, and at the same time, the terminal formed on the board forming the interposer can be firmly and stably contacted with the conductive pattern on the printed circuit board. Means / devices are required.

Meanwhile, a solder ball is used to connect the interposer and the FPC cable. That is, the solder ball is formed in the terminal of the interposer through a soldering process, and the solder ball is soldered to the contacts of the FPC cable, thereby making the electrical connection between the interposer and the FPC cable. Therefore, there is a problem that productivity is lowered because two soldering processes are performed. In order to solve this problem, it is desirable to perform the electrical connection between the terminal of the interposer and the printed circuit board and the electrical connection between the terminal of the interposer and the FPC cable without going through the soldering process.

The present invention is to solve the above problems of the interposer, there is no need for the soldering process between the connection member and the terminal of the interposer, and also the interposer that can maintain the mounting state of the interposer on the connection member The purpose is to provide an assembly.

Cover fastened to the interposer in the state; And a plurality of vertical members, the upper and lower ends of which are open, and a space in which an interposer is disposed in a space formed in the center portion.

Here, the contact of the first target member is in contact with the first contact piece of the terminal of the interposer in a state where the first connection target member (for example, FPC cable) is disposed between the interposer and the cover coupled to each other, and the second In the inner space of the frame mounted on the member to be connected (for example, a printed circuit board), an interposer with a cover is mounted so that the second contact piece of the terminal exposed outside the second surface portion of the housing of the interposer is removed. The first connection object member and the second connection object member are electrically connected through the interposer in contact with the contact formed on the second connection object member.

The frame constituting the interposer assembly according to the present invention has a mounting piece extending outward in a horizontal state at the lower end of the at least one side member so that the frame is fixed to the second connecting object member so that the frame is connected to the second connecting object member. It is fixedly mounted on.

On the other hand, the extension piece extended upward is formed in the edge part in which the vertical member is not formed among the edge parts of the horizontal member of a cover. Further, a downwardly extended stop piece of an edge portion in which no vertical member is formed among the edge portions of the horizontal member of the cover is formed.

In addition, the cover is bent inward from the bottom of the vertical member to have a horizontally extending fastening portion, so that when the cover is fastened to the housing of the interposer, the fastening portion corresponds to the bottom of the housing.
