JPH04242087A - Connector for flexible printed substrate - Google Patents

Abstract

PURPOSE:To prevent a printed substrate from being subjected to unreasonable force as well as to enable one printed substrate to be connected to plural connectors by providing each inside of the connectors with an opening section so that electrical connection can thereby be made in a state that the printed board is penetrated through. CONSTITUTION:The housing 2a of a connector 2 is provided with an opening section 2d so that a printed substrate 1 can thereby be penetrated through. When the substrate 1 is to be inserted, a slider 2b is pulled out of the housing 2a first, the board is then inserted with a lock kept in a released condition, inserting the slider 2b is kept on while the board is being penetrated through until insertion comes up to an appropriate length, and the connector 2 is then locked. The adjustment in length of an insertion of the substrate 1 can prevent the board from sagging more than required or from being excessively pulled out. And when the substrate 1 is penetrated through the opening section of the connector, the board can thereby be connected to plural connectors.

2. Description of the Related Art Conventionally, a connection between a flexible printed circuit board connector and a flexible printed circuit board has been constructed as shown in FIG. In FIG. 8, 41 is a flexible printed board, 42 is a connector for the flexible printed board, and 43 is a board on which the connector 42 is mounted.

FIG. 9 is an enlarged sectional view of the electrode portion of the connector 42 shown in FIG.
2 is a housing, 42b is a slider, and 42c is an electrode terminal.

That is, as shown in FIG. 9, in the conventional connector 42 of this type, when the flexible printed circuit board 41 is inserted into the connector 42, the tip of the flexible printed circuit board 41 hits the inside of the connector 42. , the structure is such that the flexible printed circuit board 41 cannot be inserted any further.

[0005]

However, in the conventional technology shown in FIGS. 8 and 9, if the length of the flexible printed circuit board 41 is too long, the flexible printed circuit board 41 will bend and come into contact with other parts. There have been problems in that it may be rubbed or that excessive force may be applied to the connection portion with the connector 42. Furthermore, when connecting the flexible printed circuit board 41 and the connector 42, there is a problem in that it is not possible to cope with a case where the appropriate length of the flexible printed circuit board 41 changes due to adjustment or the like.

The present invention is an attempt to solve the above-mentioned problems. That is, the present invention makes it possible to adjust the insertion length of the flexible printed circuit board when connecting the flexible printed circuit board to the connector, thereby preventing the board from slackening more than necessary or pulling too much. The object of the present invention is to provide a connector for a flexible printed circuit board that can prevent the application of excessive force and that can connect a plurality of connectors located in the front and rear or above and below with one flexible printed circuit board. be.

[0007]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a connector for a flexible printed circuit board with an opening through which the flexible printed circuit board can pass through the inside of the connector, and , electrical connection can be made with the flexible printed circuit board passing through the opening.

[0008]

[Operation] Since the present invention is provided with an opening through which a flexible printed circuit board can pass through the inside of the connector, the length of insertion of the board can be adjusted when connecting the board to the connector. This prevents excessive force from being applied to the board.

[0009]
