Description

  The present invention relates to a connector for electrical connection to a plurality of connected terminals fixed on one side of a substrate.

A module substrate in which LEDs or the like are mounted on one side of the substrate is used as a long LED lamp or the like by electrically connecting a plurality of module substrates having a predetermined length in the horizontal direction.
For example, as shown in FIG. 7, sockets 140 and 140 are fixed to one side near the ends of the substrates 40 and 40, and the sockets 140 and 140 are connected using a connector 110 having plate-like connection terminals.
However, in recent years, there is a high need for a high-density LED lamp or the like in which the distance between LEDs is narrowly arranged, and the connection method as shown in FIG. As shown in FIG. 4, a method can be envisaged in which the sockets 140A and 140A are fixed to both sides of the board 40 with the LED 2 sandwiched therebetween, and the corresponding plugs 110A and 110B are fitted into the corresponding sockets to be electrically connected. .
However, when a plug connector is provided for each corresponding socket in this way, the plug connector must be handled twice in assembly work, and in the case of 3P connection, it must be handled three times, increasing the number of assembly steps. To do.
In addition, the plug connector is small, and it is difficult to check the connection direction.
Furthermore, there is a problem that the allowable range in which the center shift and the inclination between the substrates can be absorbed is narrow.

  For example, Patent Document 1 discloses a connector for connecting substrates in a horizontal direction, and this connector also corresponds to the structure shown in FIG.

An object of the present invention is to provide a connector that is excellent in assembling workability and that is effective in absorbing mounting displacement between connected terminals fixed to one side of both sides of the board and mounting deviation between boards.
It is another object of the present invention to provide a connector that is excellent in assembling for pulling out a cable line from a board.

  A board connecting connector according to the present invention is a connector for electrical connection to a board, the board has a plurality of fixed connected terminals on one side, and the connector corresponds to each of the plurality of connected terminals on the board. A plurality of connector portions that are electrically connected to each other, and the plurality of connector portions are connected by a connecting portion that allows elastic deformation, and the connecting portion is provided integrally or separately in the connector portion. .

Here, having a plurality of connected terminals on the board means that the connected terminals are fixed to the same side of the board for each pole in two-pole electric connection or three-pole electric connection.
Accordingly, the connector portion that is electrically connected to each of the plurality of connected terminals has one connecting terminal that extends between the substrates (connected terminals) on both sides.
Here, the connected terminal fixed on one side of the board may be a socket shape or a plug shape. If the board side is a socket shape, the connector part is a plug shape. Conversely, if the board side is a plug shape, the connector part is a socket. Become a shape.

In the present invention, when the boards are connected in the horizontal direction, the plurality of boards are arranged in a substantially horizontal direction, and the connected terminals are respectively fixed to the same side of the boards on both sides to be electrically connected. The terminal portions on both sides of one connection terminal respectively provided in the above are elastically connected to the connected terminals of the substrates on both sides,
To pull out the cable wire from the board,
A plurality of connected terminals are fixed to one side of the board, and one connecting terminal provided on each of the plurality of connector parts has one end connected to a cable wire and the other end fixed to the board. It will be elastically connected to the connection terminal.

The present invention forms a plug portion for connecting a plurality of substrates in the horizontal direction or electrically connecting each of a plurality of connected terminals fixed to the substrate when drawing a plurality of cable wires from one side of the substrate. By connecting the plug portions with a connecting portion that allows elastic deformation, it is possible to absorb mounting displacement of the connected terminals attached to one side of the substrate and attachment displacement of the substrate.
In addition, since a plurality of connector portions are connected at the connecting portion, the number of assembly parts is reduced, and the assembly man-hour is reduced.
If the connecting part of the connector part is formed separately from the connector part and can be attached to the connector part, the connecting part of the connecting part should be made into a series according to the specifications of the board with different connecting terminal intervals. Therefore, the plug portion can be used in common for the board specifications between different connected terminals.
