Abstract
The present invention prevents a connection defect of a connector. In an electronic device which includes a film-like wiring board and a printed wiring board on which a connector is mounted, the film-like wiring board includes a projecting portion which projects to a side opposite to the printed wiring board at a position where the film-like wiring board is exposed from the connector into which the film-like wiring board is inserted.
Claims11
An electronic device comprising:
- a film-like wiring board which has a first lines layer and an insulating layer;
- a printed wiring board which forms second lines which are connected with first lines of the first lines layer;
- and
- a connector which is formed on the printed wiring board and into which the film-like wiring board is inserted;
- wherein the connector has a locking member which fixes the film-like wiring board to the connector;
- wherein the film-like wiring board includes a projecting portion on the insulating layer;
- and
- wherein the locking member is positioned so as to be exposed from a portion of the connector and is formed between the projecting portion of the film-like wiring board which is exposed and the portion of the connector when the film-like wiring board is inserted into the connector.

An electronic device comprising:
- a film-like wiring board which forms first lines on a surface of a film-like insulating substrate;
- and
- a printed wiring board which forms second lines which are connected with the first lines thereon;
- a connector which is formed on the printed wiring board and into which the film-like wiring board is inserted, the connector including leads which are electrically connected with the second lines, a support member which supports the leads and the film-like wiring board and a locking member which is arranged on a back side of the film-like wiring board opposite to a contact surface of the film-like wiring board with the first lines and the leads and is made to rotate about a predetermined shaft so as to bring the first lines and the leads into a contact and fixed state or to release the contact and fixed state, wherein
- the film-like wiring board includes a protective member which prevents the locking member from being shifted from the state in which the locking member brings the first lines and the leads into the contact and fixed state to a state in which the contact and fixed state is released on a surface side of a film-like insulating substrate which is brought into contact with the locking member.

A display device comprising:
- a display panel;
- a film-like wiring board which forms first lines on a surface of a film-like insulating substrate;
- a printed wiring board which forms second lines which are electrically connected with the first lines thereon, and
- a connector which is formed on the printed wiring board and into which the film-like wiring board is inserted, the connector including leads which are electrically connected with the second lines, a support member which supports the leads and the film-like wiring board and a locking member which is arranged on a back side of the film-like wiring board opposite to a contact surface of the film-like wiring board with the first lines and the leads and is made to rotate about a predetermined shaft so as to bring the first lines and the leads into a contact and fixed state or to release the contact and fixed state, wherein
- the film-like wiring board includes a protective member which prevents the locking member from being shifted from the state in which the locking member brings the first lines and the leads into the contact and fixed state to a state in which the contact and fixed state is released on a surface side of a film-like insulating substrate which is brought into contact with the locking member.
