[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a non-plugging / unplugging connector that allows a flat flexible cable such as a flexible flat cable or a flexible printed circuit board to be inserted and connected with zero insertion force.

[0002]

[Prior art]

 Conventionally, various types of non-insertion / withdrawal force connectors are known. In these systems, an actuator that presses a flexible flat cable or a flat flexible cable such as a flexible printed circuit board against the contact part of the conductive terminal inside the insulating housing is inserted and pulled out from the insulating housing. Therefore, it has been pointed out that the insertion force of the flat flexible cable cannot be reduced to zero and the height of the entire connector is increased.

Therefore, there has been proposed a non-plugging / unplugging connector in which the insertion force at the time of connecting a flat type flexible cable and the pulling out force at the time of disconnection can be made zero and the height of the entire connector can be reduced. For example, an insulating housing in which a base portion, a pair of side wall portions and an upper wall portion are integrally molded, a plurality of spring contacts (conductive terminals) fixed in juxtaposition with the base portion, a lower surface of the upper wall portion, and a base portion of the base portion. A pressing plate (actuator) for pressing the conductor on the flexible printed circuit board, which is inserted in the space defined by the upper surface and the inner surface of the side wall, to the contact part (contact part) of the spring contact. , An engaging portion formed by a front end portion of the lower surface of the upper wall portion and a rear end portion of the upper surface of the holding plate portion, and a locking means for integrally locking the holding plate portion and the insulating housing. There is an insertion / extraction force connector (Japanese Patent Publication No. 3-51257).

[0004]

[Problems to be solved by the device]

 In the non-insertion / unplug connector, the ability to insert / unplug the flat type flexible cable to zero is a top priority in terms of its function. Furthermore, the height is low and the overall size is small. It is necessary to satisfy the conditions such as the ability to achieve high efficiency, easy insertion and removal of flat flexible cables, and especially easy insertion work.

The non-insertion / withdrawal force connectors that have been proposed so far have been able to satisfy the above conditions, but the reality is that no connector that satisfies the above conditions has been proposed. When inserting the flat flexible cable, it is necessary to rotate the actuator to open the flat flexible cable insertion part. However, if the workability at this time is poor, the flat flexible cable insertion There is a problem that it is difficult to remove and it prevents proper insertion and connection.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a non-insertion / withdrawal connector that facilitates insertion of a flat flexible cable into an insulating housing.

In addition to the above, it is also an object of the present invention to provide a non-insertion / unplug force connector that facilitates the operation of the actuator when the flat flexible cable is inserted into or removed from the insulating housing.

[0008]

[Means for Solving the Problems]

 The present invention, which has been made based on the above object, enables the actuator to be fixed in a temporary holding state at that position when the actuator is rotated to open the insertion portion so that a flat flexible cable can be inserted. It is the one.

That is, according to the present invention, an insulating housing, a plurality of conductive terminals mounted side by side in the insulating housing, and a flat flexible cable inserted in the insulating housing are pressed against a contact portion of the conductive terminal. In a non-insertion-free connector having an actuator rotatably mounted in an insulating housing, the actuator includes a side plate hanging from both sides of the rear edge portion to the outside of the side surface of the housing, and a front side of the housing. It has an L-shaped arm piece that hangs outward from the side surface, and the side plate engages with a protrusion formed on the opposite side surface of the housing so as to allow the actuator to rotate, and the actuator is flat. At the open position of the rotation angle that allows the insertion of the flexible cable, the projecting piece formed on the inside of the side plate and the step formed on the opposite side surface come into contact with each other, Moreover, a connector having no insertion / removal force characterized in that the arm piece and the protrusion formed on the opposite side surface are engaged with each other.

In addition, the non-insertion / withdrawal force connector of the present invention in which the operability of the actuator is also improved, in the above-described configuration, the outer upward slopes are formed on the lower portions of both side surfaces of the insulating housing along the front and rear directions. , The actuator is arranged so as to face the lower edge of the arm piece so that the lower edge of the arm piece comes into contact with an outer upward slope to receive an upward force when the actuator is in the non-rotating closed position. .

In the non-insertion / extraction force connector of the present invention as described above, the protrusion on the side surface of the insulating housing which engages with the L-shaped arm piece of the actuator is an L-shaped protrusion, and the L-shaped protrusion is formed. The lower surface of the lower lateral portion of the projection is engageable with the upper surface of the lower lateral portion of the L-shaped arm piece in the non-rotating closed position of the actuator to ensure locking of the actuator in the closed position. Can be

[0012]

[Action]

 According to the present invention, when the actuator is in the open position of the rotation angle that allows the insertion of the flat flexible cable, the projecting piece formed on the inside of the side plate and the step portion formed on the opposite side surface are in contact with each other, and the arm is formed. Since the piece and the protrusion formed on the opposite side surface are engaged with each other, the actuator in the open position is temporarily held so as to maintain the state. Therefore, the flat flexible cable can be easily inserted without being disturbed by the actuator. If the actuator is not temporarily held, the flat flexible cable must be inserted with one hand because the flat flexible cable must be supported with one hand when inserting the flat flexible cable. As the number increases, the width of the flat flexible cable becomes larger, and such difficulty of insertion becomes a problem. The present invention solves this problem.

Further, according to the present invention, when the actuator is in the non-rotated closed position, the lower edge of the arm piece is brought into contact with the outer upward slope of the insulating housing to receive the upward force. When the actuator and the insulating housing are unlocked, the actuator can be slightly rotated in the opening direction by the upward force received from the outer upward slope. As a result, the operation for opening the actuator can be facilitated.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. 1 to 5 show a non-insertion / withdrawal force connector 1 of the embodiment. 6 to 11 are views for explaining the operation of the non-insertion / extraction force connector 1 of the embodiment.

The non-insertable / unplugging connector 1 according to the embodiment includes an insulating housing 2, a conductive terminal 3 mounted in parallel in the insulating housing 2, and a flat flexible cable inserted in the insulating housing 2 as the conductive terminal 3. An actuator 5 for pressing against the contact portion 4 of is provided. The insulating housing 2 has a structure in which a plurality of terminal mounting grooves 7 are formed in parallel on the upper surface of the base portion 6 in the front-rear direction, and an actuator pressing plate 8 is installed on the upper rear portion in parallel with the upper surface. It is a molded product.

The conductive terminal 3 is formed by punching out a thin metal plate into a shape as shown in FIG. 6 or 9, and the contact piece 9 and the mounting piece 10 are provided in a bifurcated shape. A tail 11 is projected from the outside. The conductive terminals 3 are alternately mounted in the terminal mounting grooves 7 of the insulating housing 2 from the front to the rear, and the mounting pieces 10 are hooked on the insulating housing 2, and the contact portions 4 of the contact pieces 9 are connected to the base portion 6. It is located slightly above the top surface of the. Further, the tail 11 is projected outward from the lower surface 13 of the insulating housing 2 with the tail 11 slightly protruding.

The actuator 5 is made of a plastic integrally-molded product having a U-shaped cross section or a metal plate which is processed with an insulating coating on its surface. The actuator 5 is provided on the upper surface of the base 6 of the insulating housing 2. The basic shape is a plate body having a size capable of covering a portion not covered with the holding plate 8. It is used with the insulating housing 2 lying on its side, and the lower plate 14 faces the contact portion 4 arranged on the upper surface of the base portion 6 of the insulating housing 2. The upper plate 15 is shorter than the lower plate 14, and when the lower plate 14 presses the flat flexible cable toward the contact portion 4 side, the rear end of the lower plate 14 is the lower side of the actuator pressing plate 8. On the other hand, the upper plate 15 has its rear end face opposed to the front end face of the actuator pressing plate 8 while entering. Then, a notch 16 is formed at the center of the rear end of the upper side plate 15 so that a gap into which a finger or the like can be inserted can be formed at a portion facing the actuator pressing plate 8.

On both sides of the actuator 5, a side plate 18 hanging outward from the side surface 17 of the insulating housing 2 and an L-shaped arm piece 19 are provided. The side plate 18 is a J-shaped plate body that is hung continuously from the rear end side portion of the upper plate 15. The side plate 18 is engaged with an engaging protrusion 20 having side edges protruding from the opposite side surfaces 17 of the insulating housing 2, so that the actuator 5 can rotate around the engaging protrusion 20. Is allowed. On the other hand, the L-shaped arm piece 19 is connected downward from the front edge of the side plate 18 to the front end of a lateral support plate 21 which is continuously connected in a cantilever manner from the front side edge of the side plate 18. The length of the directional portion 19a is set to reach the lower portion of the insulating housing 2 sufficiently.

The side surface 17 of the insulating housing 2 facing the side plate 18 is formed with a step portion 22 on the lower outer side, and when the actuator 5 rotates, the J-shaped side plate 18 forms the step portion 22. It is designed to pass between the engaging projections 20. As shown in FIGS. 4 and 5, a projecting piece 23 is formed at a right angle on the inner side of the tip of the side plate 18, and is protruded to the outside of the actuator retainer 8 so as to face the upper surface of the projecting piece 23. 24 are connected in series and serve as a stopper mechanism for rotation of the actuator 5 in the closing direction. Further, as shown in FIGS. 4 and 5, a step portion 25 is formed below the eaves 24 and the engaging projection portion 20 on the side surface 17 so as to face the lower surface of the projection piece 23. Thus, when the actuator 5 rotates in the opening direction, the projecting piece 23 abuts the step portion 25 to stop the rotation in the opening direction. The angle at which the rotation of the actuator 5 in the opening direction is stopped is an angle that does not hinder the insertion of the flat flexible cable to be connected, and is, for example, about 30 degrees.

Further, an L-shaped protrusion 26 is formed on the front portion of the side surface 17 of the insulating housing 2. The projection 26 is sized to fit inside the L-shaped arm piece 19, and when the actuator 5 is rotated, the tip 19b of the arm piece 19 slides on the outer side surface of the L-shaped projection 26. I am trying to move. When the projecting piece 23 comes into contact with the step 25 and the rotation of the actuator 5 is stopped, the tip 19b of the arm piece 19 engages with the upper end of the L-shaped projecting section 26, and in this state, the actuator The 5 is temporarily held in that position without rotating.

The side surface 17 of the insulating housing 2 having the L-shaped protrusion 26 is further extended to a position where the lateral portion 19c of the L-shaped arm piece 19 reaches, that is, a lower portion of the side surface 17. Facing slopes 27 are formed along the front-back direction. The slope 27 is arranged so as to face the lower edge of the lateral portion 19c of the arm piece 19 in the vertical direction, and when the actuator 5 is in the closed position shown in FIG. Is deformed outward. Therefore, in this deformed state, as a result of the arm piece 19 attempting to return by elastic force, an upward force acts on the arm piece 19 due to the return elastic force and the action of the slope 27, and the actuator 5 is rotated in the opening direction. Power will be generated.

Reference numeral 28 in the drawing denotes an engaging piece projecting from the front end side edge of the lower plate 14 of the actuator 5, and when the actuator 5 is in the closed position, the engagement piece has an inner end portion at the front end side edge of the insulating housing 2. It is adapted to be locked by engaging the lower surface of the eaves 29 provided in the direction. Reference numeral 30 denotes a ring formed by projecting the inner surface of the side plate 18 into a hemispherical shape. The ring 30 is in contact with the side surface 17 of the insulating housing 2 so that the actuator 5 can be rotated easily. It was done.

Next, with reference to FIGS. 6 to 11, the operation of the non-insertion / withdrawal connector 1 of the above embodiment will be described. FIG. 6 shows a state in which the flat flexible cable is not yet inserted, the actuator 5 is in the closed position, the front end of the lower plate 14 is engaged with the lower side of the actuator pressing plate 8, and the lower plate 14 is The engaging piece 28 on the side edge of the front end of the is engaged with the eave 29 on the insulating housing 2 side and is in a locked state. When connecting a flat flexible cable to the non-insertion / withdrawal connector 1 in this state, first, as shown by the arrow 31, slide the actuator 5 forward to lock the engagement piece 28 and the eaves 29. remove.

In the closed position, the actuator 5 receives a force to rotate in the opening direction from the slope 27 on the side of the insulating housing 2 via the arm piece 19, so that when the engagement piece 28 and the eaves 29 are unlocked. The front end of the actuator 5 is flipped upward as shown in FIG. Therefore, the front end side of the flipped-up actuator 5 is pulled up further to rotate the actuator 5 as shown by the arrow 32 in FIG. 8 to open it so that the flat flexible cable can be inserted. Easy to operate.

As shown in FIG. 8, the rotation of the actuator 5 in the opening direction stops when the projecting piece 23 provided on the side plate 18 comes into contact with the step portion 25 on the insulating housing 2 side, and the L-shaped arm. The tip 19b of the piece 19 engages with the upper end of the L-shaped projection 26 on the insulating housing 2 side and is temporarily held. Therefore, even if the actuator 5 is released, the actuator 5 is maintained in the open position. As a result, when the flat flexible cable is inserted, the actuator 5 does not move and hinder the cable insertion, and the flat flexible cable can be supported and inserted by both hands. In combination with zero insertion force, the insertion work can be extremely easy.

FIG. 9 shows a state in which the flat flexible cable 33 is inserted. The connection end 34 of the flat flexible cable 33 is placed between the upper surface of the base 6 of the insulating housing 2 and the lower plate 14 of the actuator 5, and the contact portion 4 of each conductive terminal 3 and the conductive portion of the flat flexible cable 33 face each other. To insert. As described above, since the actuator 5 is maintained in the temporary holding state in the open position to facilitate the insertion work of the flat flexible cable 33, the contact portion 4 and the conductive portion on the cable 33 side should be properly opposed to each other. You can

When the insertion of the connection end 34 of the flat flexible cable 33 is completed as described above, the actuator 5 is rotated in the closing direction as shown by the arrow 35, as shown in FIG. Next, as shown in FIG. 11, the actuator 5 is slid laterally as shown by the arrow 36 to engage the engagement piece 28 of the lower plate 14 of the actuator 5 with the eaves 29 of the insulating housing 2. Lock it in the closed state. In this state, the rear end portion of the lower side plate 13 enters the lower side of the actuator pressing plate 8, so that the actuator 5 inserts the flat flexible cable 33 through the lower side plate 14 into the contact portion 4 side of the conductive terminal 3. , And both are electrically connected. In the closed state, the lower surface of the lower lateral portion of the L-shaped protrusion 26 also engages with the upper surface of the lower lateral portion 19c of the arm piece 19, so that the locking can be reliably performed.

When the flat flexible cable 33 is disconnected, the reverse operation to the above is performed. When the actuator 5 is slid in the direction opposite to the arrow 36 and the engagement piece 28 and the eaves 29 are disengaged, the front end side of the actuator 5 is moved upward by the force received from the slope 27 via the arm piece 19. Also in this case, the turning operation in the opening direction can be facilitated because it is flipped up. Further, since the actuator 5 in the open state can be maintained in the temporary holding state, the connecting end 34 of the flat type flexible cable 33 does not get caught on the actuator 5 when the flat type flexible cable 33 is pulled out, and the pulling out operation can be facilitated.

As described above, when the actuator is rotated to the open state, the actuator can be maintained in the temporary holding state at the open position. Therefore, the flat flexible cable can be inserted and withdrawn. Can be made easier. Further, when the actuator is unlocked from the insulating housing, the actuator can be flipped up in the opening direction, which facilitates the opening operation of the actuator.
