  A flat flexible wiring connector 1 according to an embodiment of the present invention is provided with a flexible wiring board 10 (hereinafter referred to as FPC) as a flat flexible wiring and a FPC 10. In addition, the slider 30 having the terminal insertion portion 40 to which the terminal 12 formed at the end portion 11 of the FPC 10 by being inserted into the mating connector 100 and the mating terminal 110 in the mating connector 100 are connected, and the FPC 10 And a slider cover 50 assembled to the slider 30 so as to be sandwiched between the slider 30 and the slider 30.

First, the known mating connector 100 will be described.
As shown in FIG. 1, the mating connector 100 includes a box-shaped housing part 120 in which an opening part 120 a into which the terminal insertion part 40 of the slider 30 is inserted is formed in a rear end part 120 b, and a housing part 120. A plurality of mating terminals 110 are provided in the accommodation space 120 c and connected to the terminals 14 of the FPC 10. Each mating terminal 110 is electrically connected to a circuit board (not shown) at the lower part of the housing part 120, for example.

  The upper surface 120d of the housing part 120 is provided with a locking protrusion 121 that is engaged with a connector engaging part 32 (to be described later) of the slider 30, and the engaging protrusion 121 and the connector engaging part 32 are engaged with each other. The flat flexible wiring connector 1 is fixed to the mating connector 100.

Next, the FPC 10 will be described.
As shown in FIGS. 8 and 9, the FPC 10 has circuit wiring 12 formed by patterning a conductive metal film, and a flat plate shape in which both surfaces of the circuit wiring 12 are covered with an insulating thin film 13. A flexible circuit board.
A plurality of terminals 14 are formed side by side on the end portion 11 of the FPC 10 so that each terminal 14 can be connected to each counterpart terminal 110, so that the connection surface 14 a on the connection side of each terminal 14 is exposed. Part of the insulating thin film 13 has been removed.

  In addition, circular positioning holes 16 are formed at both end portions 15 in the left-right direction of the FPC 10. When the FPC 10 is assembled to the slider 30, the positioning projections 31 e, which will be described later, which are projected from the mounting surfaces 31 c described later of the slider 30 are inserted into the positioning holes 16, thereby positioning the mounting position of the FPC 10 with respect to the slider 30. It has become so.

The FPC 10 has a reinforcing plate 20 attached to the back surface 10b of the surface 10a on the side that contacts the mounting surface 31c of the slider 30, that is, the surface 10a on the side where the terminal 11 is exposed. , To increase the strength.
The reinforcing plate 20 is made of a metal plate or the like, and is formed so that the end portion 11 of the FPC 10 is exposed. That is, the end portion 11 of the FPC 10 has high flexibility and is easily bent. The reinforcing plate 20 has positioning holes 21 corresponding to the positioning holes 16 and is attached to the slider 30 in a state of being bonded to the FPC 10.

In addition, although the reinforcement board 20 illustrated what was affixed on the back surface 10b of the surface 10a by which the terminal 11 is exposed, it is not restricted to this. That is, the reinforcing plate 20 may be attached to the back surface 10b. In this case, the end portion 11 is exposed so that the connection surface 14a of the terminal 14 is exposed.
In the embodiment of the present invention, the reinforcing plate 20 is formed such that the end portion 11 of the FPC 10 is exposed. However, the present invention is not limited to this. That is, the FPC 10 may be covered with the reinforcing plate 20 including the end portion 11. In this case, the reinforcement board 20 shall be affixed on the back surface 10b.

Next, the slider 30 will be described.
The slider 30 is made of an insulating material, and has a slider base 31, a connector engaging portion 32 provided on the upper portion 31 a of the slider base 31, and a terminal insertion portion 40 as shown in FIGS. 10 to 13. It becomes.

  The slider base 31 is a base formed in a substantially rectangular parallelepiped shape, and has a mounting surface 31c to which the FPC 10 is mounted on the lower surface 31b. Positioning protrusions 31e that protrude downward from the attachment surface 31c are formed at both end portions 31d in the longitudinal direction of the attachment surface 31c. When the FPC 10 is assembled to the slider 30, the positioning protrusions 31 e are inserted into the positioning holes 16 of the FPC 10, whereby the mounting position of the FPC 10 with respect to the slider 30 is determined.

  The connector engaging portion 32 is for fixing the flat flexible wiring connector 1 and the mating connector 100 by being engaged with a locking projection 121 provided on the mating connector 100.

  The terminal insertion portion 40 is a portion that connects the terminal 14 and the mating terminal 110 in the mating connector 100 when the FPC 10 is attached and is inserted into the mating connector 100. As shown in FIG. 13, the terminal insertion portion 40 is provided so as to protrude from the lower front end 31f of the slider base 31 so that the mounting surface 31c extends forward.

Further, the terminal insertion part 40 has a bent holding part 41.
The bending holding portion 41 has a slit-like insertion opening 42 formed on the mounting surface 31c so that the end 11 of the FPC 10 can be inserted, and the end 11 is inserted into the insertion opening 42. When the slider cover 50 is assembled, as shown in FIG. 5, the end 11 is a portion that is bent and held in the insertion opening 42 from the mounting surface 31 c.
More specifically, the bending holding part 41 is bent and held by the bending holding part 41 so that the distance from the contact surface 110a of the mating terminal 110 becomes larger toward the edge 11a.
Further, the insertion opening 42 is formed by forming each opening inner wall surface 42 a of a pair of opening inner wall surfaces 42 a forming a side in the longitudinal direction along the bending direction of the end portion 11. For this reason, the end portion 11 is easily bent at a predetermined angle by the bending holding portion 41. That is, after the end portion 11 is inserted into the insertion opening 42, the end portion 11 is bent toward the mounting surface 31c, whereby the end portion 11 is bent at a predetermined angle.

Such a bent holding portion 41 prevents the edge 11 a of the end portion 11 from coming into contact with the mating terminal 110. That is, the end portion 11 is protected by the bent holding portion 41.
In addition, each terminal 14 is formed with an inclined surface 14b that is inclined so that the distance from the contact surface 110a of each counterpart terminal 110 is increased. By forming such an inclined surface 14b, when the terminal insertion part 40 is inserted into the mating connector 100, each terminal 14 is first brought into contact with the mating terminal 110. Thus, the terminals 14 and the mating terminals 110 are brought into contact with each other smoothly.

Next, the slider cover 50 will be described.
The slider cover 50 is a plate-shaped member having a substantially rectangular shape whose longitudinal direction is the longitudinal direction of the slider 30, and as shown in FIG. 4, both edges 51 in the longitudinal direction are bent upward to form side portions of the slider 30. 31g is contact | abutted. As shown in FIG. 6, fixing holes 53 into which positioning protrusions 31 e are inserted are formed at both ends 52 of the slider cover 50 in the longitudinal direction. The slider cover 50 is fixed to the slider 30 by inserting the positioning projection 31 e into the fixing hole 53.

  As shown in FIG. 14, such a flat flexible wiring connector 1 is bent so that the end 11 is protected by the bending holding portion 41 and the inclined surface 14 b is formed on the terminal 14. Therefore, when the terminal insertion portion 40 is inserted into the mating connector 100, the terminals 14 and the mating terminals 110 are smoothly brought into contact with each other.

  Next, a flow from when the terminal insertion portion 40 starts to be inserted into the mating connector 100 to when the flat flexible wiring connector 1 and the mating connector 100 are fixed will be described with reference to FIG. FIG. 15 is a diagram showing a flow from when the terminal insertion portion 40 starts to be inserted into the mating connector 100 to when the flat flexible wiring connector 1 and the mating connector 100 are fixed.

  First, when the operator or the like starts inserting the terminal insertion portion 40 into the mating connector 100, the bent holding portion 41 is brought into contact with the mating terminal 110 (see FIG. 15A). For this reason, the edge 11a of the end portion 11 is not in contact with the mating terminal 110, and damage such as deformation of the end portion 11 can be prevented.

  Thereafter, when the terminal insertion portion 40 is further inserted into the mating connector 100 by an operator or the like, each mating terminal 110 comes into contact with the inclined surface 14b of each terminal 14 (see FIG. 15B). As described above, when each terminal 14 is brought into contact with each counterpart terminal 110, each of the terminals 14 and each counterpart terminal 110 are smoothly brought into contact with each other by first contacting the inclined surface 14 b.

  Thereafter, when the terminal insertion portion 40 is inserted up to the mounting position in the mating connector 100 by an operator or the like, the locking protrusion 121 and the connector engaging portion 32 are engaged (see FIG. 15C). Thereby, the connection between the flat flexible wiring connector 1 and the mating connector 100 is completed.

  Next, the assembly procedure of the flat flexible wiring connector 1 will be described with reference to FIG. FIG. 16 is a view showing an assembling procedure of the flat flexible wiring connector 1.

  First, the operator inserts the end portion 11 of the FPC 10 into the insertion opening 42 from obliquely below the slider 30 (see FIG. 16A). At this time, by visually observing the insertion opening 42 from above the slider 30, it can be easily confirmed whether or not the end portion 11 is inserted into the insertion opening 42.

  Thereafter, the operator attaches the slider cover 50 and the FPC 10 to the slider 30 so that the positioning protrusion 31e is inserted into the positioning hole 16 and the back surface 10b of the FPC 10 is in contact with the mounting surface 31c (see FIG. 16B). ). In this manner, the end portion 11 of the FPC 10 is bent and is held by the bending holding portion 41 in a state where the end portion 11 is bent.

  Thereafter, the operator fixes the slider cover 50 to the slider 30 by inserting the positioning protrusion 31e through the fixing hole 53 of the slider cover 50 (see FIG. 16C). As a result, the FPC 10 is sandwiched between the slider 30 and the slider cover 50 with the end 11 bent. Thus, the assembly work of the flat flexible wiring connector 1 is completed.

  In the flat flexible wiring connector 1 according to the embodiment of the present invention, the terminal insertion portion 40 has a slit-like insertion opening 42 formed on the attachment surface 31c so that the end portion 11 can be inserted, When the slider cover 50 is assembled in a state where the end portion 11 is inserted into the insertion opening portion 42, the bent holding portion 41 is bent and held in the insertion opening portion 42 from the attachment surface 31c. Therefore, it is possible to easily check whether the end portion 11 is protected by the bending holding portion 41 and whether the end portion 11 is protected by the bending holding portion 41 via the insertion opening 42. Therefore, the assembling work can be facilitated while preventing the electrical characteristics from deteriorating.

  In the flat flexible wiring connector 1 according to the embodiment of the present invention, the end portion 11 is bent by the bending holding portion 41 so that the distance from the contact surface 110a of the mating terminal 110 increases toward the edge 11a. Therefore, when the terminal insertion portion 40 is inserted into the mating connector 100, the inclined surface 14b of each terminal 14 and each mating terminal 110 are smoothly brought into contact with each other, so that damage to each terminal 14 is prevented. As a result, it is possible to prevent the electrical characteristics from being deteriorated.

  Further, in the flat flexible wiring connector 1 according to the embodiment of the present invention, each opening inner wall surface 42a of the pair of opening inner wall surfaces 42a in which the insertion opening 42 forms a longitudinal side is the bending direction of the end portion 11. Therefore, the end 11 can be easily bent at a predetermined angle by the bent holding portion 41.

  In the flat flexible wiring connector 1 according to the embodiment of the present invention, the reinforcing plate 20 is attached so that the FPC 10 is exposed so that the end 11 is exposed. The end portion 11 can be easily bent while improving the strength of the portion, and as a result, the assembling work can be facilitated.

  In the embodiment of the present invention, the FPC 10 has been described as the flat flexible wiring. However, any other flat flexible wiring may be used. For example, a flexible flat cable may be used.

  Further, in the embodiment of the present invention, the end portion 11 is bent and held by the bending holding portion 41 so that the distance from the contact surface 110a of the mating terminal 110 is increased toward the edge 11a. However, it is not limited to this. That is, when the slider cover 50 is assembled with the end 11 inserted into the insertion opening 42, the end 11 is bent and held in the insertion opening 42 from the mounting surface 31c. That's fine. For example, the end portion 11 may be bent and held in the vertical direction by the bending holding portion 41.

  In the embodiment of the present invention, the reinforcing plate 20 is affixed to the FPC 10. However, the present invention is not limited to this, and a configuration that does not use the reinforcing plate 20 may be used.

  As mentioned above, the invention made by the present inventor has been specifically described based on the embodiment of the invention described above, but the invention is not limited to the embodiment of the invention described above, and departs from the gist thereof. Various changes can be made without departing from the scope.
