Abstract

A cable holding member includes a stopper member and a housing. The stopper member has an attachment surface for supporting a flat cable in a folded state. The housing has a mounting surface which is provided at an opening edge of a housing space for housing the stopper member and on which the flat cable is to be placed, and recesses into which protrusions of the flat cable placed on the mounting surface are to be fitted. The flat cable is placed on the mounting surface, and then, the stopper member is inserted into the housing space of the housing. In this way, the stopper member is attached to the housing with the flat cable being supported on the attachment surface.

First claim

The invention claimed is:

1. A cable holding member, comprising:
a stopper member having an attachment surface on which a flat cable in a strip shape is to be attached in a folded state; and
a housing, the housing comprising:
a housing space for housing the stopper member,
a mounting surface which is provided at an opening edge of the housing space and on which the flat cable is to be placed, and
a positioning section for positioning the flat cable placed on the mounting surface, wherein

the housing is configured such that the stopper member and the flat cable are attachable to the housing with the flat cable being in a folded state, the folded state being achieved by pressing the flat cable placed on the mounting surface by inserting the stopper member into the housing space.

2. The cable holding member according to claim 1 , wherein
the positioning section is a recess into which a protrusion protruding outwardly in a width direction of the flat cable from an edge of the flat cable is to be fitted.

3. The cable holding member according to claim 1 , wherein
the stopper member has a stepped part protruding from the attachment surface to a side on which the flat cable is to be placed, the stepped part being configured to catch an engaged section of the flat cable.

4. The cable holding member according to claim 1 , wherein
the stopper member and the housing have a direction control section configured to control an attachment direction of the stopper member to insert the stopper member into the housing space in a regular attachment direction.

5. The cable holding member according to claim 1 , wherein
the housing has a curved surface part at a portion of the housing facing a surface of the flat cable at the opening edge of the housing space, the curved surface part having an opening width decreasing toward an interior of the housing space.

6. A plug connector, comprising:
the cable holding member according to claim 1 ; and
the flat cable which is to be attached to the stopper member to be in a folded state and is to be partially inserted into the housing space of the housing.

7. The plug connector according to claim 6 , wherein
the flat cable has a flexible structure at a portion at which the flat cable is folded by the stopper member, the flexible structure rendering the portion more flexible than a remaining portion of the flat cable.

8. The plug connector according to claim 7 , wherein
the flexible structure is a penetrating part formed through the flat cable in a thickness direction of the flat cable.

9. The plug connector according to claim 8 , wherein
the stopper member has a lug to be fitted into the penetrating part.

10. A connector device, comprising:
the plug connector according to claim 6 ; and
a receptacle connector which supports a terminal to electrically connect with an electric conductor of the flat cable and to which the plug connector is detachably connectable.

11. The connector device according to claim 10 , wherein
the terminal has contact pieces provided in a pair and facing each other with a gap for receiving the flat cable being provided therebetween,
each of the contact pieces in the pair has a contact point to electrically contact with a conductive part on a surface of the flat cable,
the contact point is formed by processing a metal plate, and
the contact point has a part coming into contact with the conductive part and having a thickness direction parallel to a thickness direction of the flat cable.

12. The connector device according to claim 11 , wherein
the contact pieces in the pair are flexibly deformable in a direction in which the contact pieces in the pair face each other,
the terminal includes
base parts provided in a pair and each having a plate shape and arranged parallel to the surface of the flat cable, and
protection parts provided in at least a pair and protruding from edges of the base parts in the pair parallel to a connection direction of the flat cable so as to be close to the flat cable,

the contact pieces in the pair correspond to the base parts in the pair on a one-to-one basis and to the protection parts in the pair on a one-to-one basis, and
each of the contact pieces in the pair is formed by bending an end in the connection direction of a corresponding one of the base parts in the pair to be surrounded by the corresponding one of the base parts in the pair and any one of the protection parts in the pair.

13. The connector device according to claim 12 , wherein
a distance between the contact pieces in the pair decreases as a distance from a part at which each of the contact pieces in the pair is connected to the corresponding one of the base parts in the pair to the contact point decreases.

14. The flat cable, comprising:
a substrate having a strip shape and being foldable by the stopper member of the cable holding member according to claim 1 , wherein
the substrate has a flexible structure at a portion at which the substrate is folded by the stopper member, the flexible structure rendering the portion more flexible than a remaining portion of the substrate.

15. The flat cable according to claim 14 , wherein
the flexible structure is a penetrating part formed through the substrate in a thickness direction of the substrate.

16. A method for assembling the plug connector according to claim 6 , comprising:
placing the flat cable on the mounting surface to straddle an opening edge of the housing space of the housing with the flat cable being positioned by the positioning section;
inserting the stopper member into the housing space while the flat cable placed on the mounting surface is pressed into the housing space by a top end of the stopper member; and
stopping the inserting the stopper member when the stopper member is inserted into the housing space to a position at which the stopper member is locked in the housing by a lock structure provided to the stopper member and the housing.
