Abstract

The present invention relates to a floating receptacle connector that electrically connects substrates, and more specifically, to a floating receptacle connector that enables electrical connection between a receptacle connector and a plug connector by applying an FPC (Flexible Printed Circuit) cable to an elastic contact terminal responsible for the floating role of an internal housing. To this end, the present invention is characterized by comprising: an outer housing fixed with a plurality of terminals facing each other and electrically connected to terminals of a substrate inside; an inner housing installed to be received in the internal space of the outer housing; anchor plates installed at both ends of the outer housing and the inner housing to allow the inner housing to float from the outer housing; and a pair of symmetrical "U" shaped FPC cables, each having a pattern formed on an outer surface that is electrically connected to each terminal fixed to the outer housing, and a pattern formed on an inner surface that is electrically connected to terminals of a plug connector, with one end fixed to the outer housing and the other end fixed to the inner housing.

Claims (5)

A floating receptacle connector characterized by comprising: an outer housing fixed with a plurality of terminals facing each other and electrically connected to terminals of a circuit board inside; an inner housing installed to be received in the inner space of the outer housing; anchor plates installed at both ends of the outer housing and the inner housing to cause the inner housing to float from the outer housing; and a pair of symmetrical "U" shaped FPC cables, each having a pattern formed on an outer surface that is electrically connected to each terminal fixed to the outer housing, and a pattern formed on an inner surface that is electrically connected to terminals of a plug connector, with one end fixed to the outer housing and the other end fixed to the inner housing.
In claim 1, A floating receptacle connector characterized by forming a catch projection at each end of each of the above FPC cables, and forming a catch projection in each of the outer housing and inner housing that engages with the catch projection of the FPC cable to support the FPC cable, wherein the catch projection formed in the outer housing and inner housing is respectively fitted into and engaged with the catch projection formed in the FPC cable, thereby supporting the FPC cable in the outer housing and inner housing.
In claim 1, A floating receptacle connector characterized by having a viewing window formed at least one location in the outer housing and inner housing to check the mounting status of an FPC cable.
In claim 1, A floating receptacle connector characterized by symmetrically forming a first fixing hole at one end of the outer housing and forming protruding pieces having second fixing holes at each end of the inner housing, thereby fixing a first fixing part of an anchor plate to the first fixing hole and fixing a second fixing part of an anchor plate to the second fixing hole of a protruding piece so that the inner housing is floated from the outer housing by means of an elastic part of the anchor plate.
In claim 4, A floating receptacle connector characterized by forming an insertion groove on the upper surface of the above-mentioned protruding piece so that the upper part of the anchor plate is fitted into the insertion groove.

Description

Floating receptacle connector The present invention relates to a floating receptacle connector that electrically connects substrates, and more specifically, to a floating receptacle connector that enables electrical connection between a receptacle connector and a plug connector by applying an FPC (Flexible Printed Circuit) cable to an elastic contact terminal responsible for the floating role of an internal housing. Generally, to electrically connect substrates, a board-to-board connector (hereinafter referred to as 'connector') consisting of a receptacle connector mounted on one substrate and a plug connector mounted on the other substrate is used. However, since such connectors cannot maintain a stable connection state in environments where continuous vibration occurs, such as vehicles, the development of connectors capable of solving this problem has recently been actively pursued, and as an example, the "Automotive PCB Connector" disclosed in Korean Registered Patent No. 1294155 is known. As shown in FIG. 1, the automotive PCB connector is composed of a receptacle connector (10) mounted on a first substrate (10') on one side and a plug connector (20) mounted on a second substrate (20') on the other side. The above receptacle connector (10) comprises a first housing (11) separated into an outer housing (12) and an inner housing (13), and a plurality of first contact terminals (14) that connect the outer housing (12) and the inner housing (13) and contact a plug connector (20). One side of the first contact terminal (14) is assembled to the outer housing (12) and mounted on the first substrate (10'), while the other side is assembled to the inner housing (13). Accordingly, the inner housing (13) is electrically connected to the outer housing (12) in a floating state by the first contact terminal (14) while spatially separated from the outer housing (12). The plug connector (20) has a second housing (21) and a plurality of second contact terminals (24) assembled to the second housing (21) and in contact with the first contact terminal (14). In a connector configured as described above, when the receptacle connector (10) and the plug connector (20) are combined, the second contact terminal (24) is inserted into the U-shaped portion (14c) of the first contact terminal (14), thereby establishing electrical contact between them. As a result, the inner housing (13) of the receptacle connector (10) becomes movable relative to the outer housing (12), and at the same time, the second housing (21) coupled to the inner housing (13) also becomes movable relative to the outer housing (12), allowing a stable connection state to be maintained even against external shocks or vibrations.
