Description

  The present invention relates to a flat conductor attachment and a flat conductor connector having the same.

  As the flat conductor, a flexible substrate (FPC), a flat cable, and the like are known. Such a flat conductor is often connected to an electrical connector (also simply referred to as a connector) attached to a circuit board. As a connector to which such a flat conductor is connected, for example, there is a connector disclosed in Patent Document 1.

  The flat conductor originally has flexibility, but the number of terminals of the connector has been increasing recently. Therefore, the flat conductor has a large number of conductor portions at the connection portion connected to the terminal. As a result, the width of the flat conductor is increased. As a result, the flat conductor is more easily bent in the width direction. When the flat conductor is inserted into the connector, this bending makes the insertion operation difficult. Therefore, for example, in Patent Document 1, an attachment called a plug housing is attached in order to give rigidity to one end side of a flat conductor (FPC) on the insertion side to the connector and keep it flat. This plug housing is composed of a front member and a back member, and these members are joined in a state of being arranged on both sides of the FPC. The front member is cut out at a portion corresponding to the front edge of the FPC, and the conductor portion of the connecting portion of the FPC is exposed on the back member. The back member has insertion portions that are guided and inserted into corresponding portions of the housing on both side edges outside the arrangement range of the conductor portions. Thus, the FPC which is held by the plug housing and has increased rigidity is guided and inserted into the connector housing called the base housing of the connector together with the plug housing, and the connection portion where the conductor portion is exposed together with the back member and the upper and lower sides of the connector terminal. The gap between the two elastic arm portions is increased to enter between the two elastic arm portions, and contacted with the contact portion of the upper elastic arm portion.

JP 11-329619

  In Patent Document 1, the FPC connecting portion held by the plug housing is in a state where its rigidity is increased, while resisting the frictional force between these contact portions together with the back member of the plug housing. enter in. At that time, the operator pushes the plug housing to a predetermined position where the tip of the plug housing comes into contact with the inner back wall of the base housing while feeling a resistance force due to constant friction.

  According to Patent Document 1, since the back member of the plug housing exists below the connecting portion of the FPC, the corresponding portion of the connector housing that receives the connecting portion includes not only the connecting portion but also the back member. Space is also required. That is, compared to a connector housing that accepts only the connection portion of the FPC, the connector housing becomes higher by the amount of the back member, leading to an increase in size of the connector.

  Further, since the operator always feels the resistance force, there is a possibility that the operator mistakes that the predetermined position has been reached and stops the insertion halfway. In such a case, the connection with the contact portion of the terminal of the connector also leads to problems.

  Furthermore, the resistance is not so strong because it does not prevent the plug housing from being inserted. In other words, even if it is not so large, the FPC can be easily displaced and pulled out when an inadvertent external force is applied. It is easy to occur.

  In view of such circumstances, the present invention is attached to the distal end side of the flat conductor without increasing the height of the housing of the connector, increases the rigidity at the connection portion of the flat conductor, and connects to the connector. It is an object of the present invention to provide a flat conductor attachment and a flat conductor connector having the flat conductor attachment that also prevent inadvertent disconnection later.

  The present invention relates to an attachment for a flat conductor and a flat conductor connector having the same.

<Flat conductor attachment>
In the flat conductor attachment according to the present invention, a receiving portion for receiving a connecting portion of a flat conductor in which conductor portions are arranged on one end side is formed in the housing, and a contact portion in contact with the conductor portion is arranged in the receiving portion. A flat conductor connected to a connector having a movable member having a plurality of terminals and having a pressurizing portion that presses the flat conductor inserted into the receiving portion against the contact portion.

  In such a flat conductor attachment, in the present invention, the attachment has an attachment portion for attaching the flat conductor to a predetermined position, and an insertion portion inserted into the housing outside the arrangement range of the conductor portions. The connection portion is exposed on both sides in the arrangement range.

  The attachment having such a configuration is attached to a predetermined position of the flat conductor by the attachment portion, and increases the rigidity of the flat conductor. In the state where the attachment is attached to the flat conductor, the connection portion which is the arrangement range of the conductor portions is exposed and the attachment portion is absent, and the flat conductor can be increased in rigidity as described above outside the connection portion. . After the attachment is attached to the flat conductor, the insertion portion of the attachment provided outside the connecting portion is inserted into the insertion portion of the housing and reliably guided to the normal position. Even if an attachment is attached to the flat conductor, the connection part is exposed as described above. In other words, there is no attachment part on both sides of the connection part, and only the connection part is present. Enter the receiving part of the housing. Therefore, it is sufficient that the receiving portion has a space high enough to accommodate the connecting portion, and the height of the housing can be small.

  In the present invention, when the flat conductor is pulled rearward in the extraction direction with the connecting portion of the flat conductor inserted forward to the normal position of the receiving portion, the movable member at the pressing position is It is preferable to have the to-be-latched part latched by this latching | locking part. In such a configuration, the movable member is in the open position before moving to the pressurization position, allows insertion of the attachment, and moves to the pressurization position after insertion to the normal position of the attachment. A stop part latches to the to-be-latched part of an attachment, and prevents extraction of a flat conductor. That is, when using a connector in which the flat conductor is pressed by the movable member and is in contact with the contact portion of the terminal with contact pressure, the flat conductor does not come off.

  In the present invention, the locked portion is a contact portion that interferes with the contacted portion of the movable member at the half-insertion position where the attachment has not reached the normal position and prevents the movable member from moving to the pressurizing position. It is preferable to have.

  The attachment being in the half insertion position means that the connecting portion of the flat conductor has not reached the receiving portion to the predetermined position, and this incomplete insertion state means that the movable member has moved to the pressurizing position. It can be confirmed simply by visual inspection. Therefore, this situation can be avoided by inserting the attachment again.

  In the present invention, the attachment portion is preferably provided outside the arrangement range of the conductor portions in which the flat conductor is contact-connected to the contact portion of the terminal. Usually, the flat conductor has ears on both edges in the width direction, that is, outside the range of the conductor part, and the attachment part can be attached to the ear part.

<Connector with attachment>
The above-described attachment can be provided in the connector in advance as a component constituting the connector.

  In the connector according to the present invention, the housing is formed with an insertion portion that receives an insertion portion located outside the arrangement range of the conductor portion provided in an attachment attached to a predetermined position of the flat conductor, and the arrangement When the movable member is subjected to a movement operation toward the pressurizing position in a state where the connection portion is exposed on both sides and the connection portion is inserted forward to the normal position of the receiving portion, the attachment and It is characterized in that it can be moved to the pressure position without interference.

  Under such a configuration, when the connecting portion of the flat conductor is inserted into the receiving portion of the housing, the movable member is subjected to a moving operation toward the pressure position. In this case, when the connecting portion, that is, when the attachment has reached the normal position, the movable member moves to the pressing position without interfering with the attachment, and pressurizes the flat conductor.

  In the present invention, the movable member is provided with a locking portion for locking the movable member at the pressing position to the locked portion of the attachment when the flat conductor is pulled backward in the extraction direction. It is preferable. Even when the flat conductor is inadvertently subjected to external force in the pulling direction when the connector is used, the locked portion of the attachment securely locks with the locking portion of the movable member in the same direction. Extraction of the flat conductor is reliably prevented.

  In the present invention, when the movable member is in the half-insertion position where the attachment has not reached the normal position, the movable member interferes with the contact portion of the attachment and is prevented from moving to the pressure position of the movable member. It is preferable to have a contact part. In this way, when the attachment is in the half insertion position, that is, when the connecting portion of the flat conductor is not inserted up to the predetermined position, the contacted portion of the movable member can be operated even if the movable member is moved toward the pressing position. Interferes with the contact portion of the attachment, and the movable member is prevented from moving to the pressurizing position and remains in the middle position. The fact that such a movable member is in the middle position can be easily grasped visually, so that the flat conductor is inserted again.

  In the present invention, the terminal has a guide portion that guides when the upper arm portion and the lower arm portion are connected to each other at the front by a connecting portion, and the upper arm portion moves to the closed position of the movable member at the rear portion, A contact part is provided at the rear part of the lower arm part, and when the movable member rotates and moves to the pressurizing position, a part of the movable member presses the flat conductor to contact the flat conductor and the contact part. When the movable member rotates from the vertical position to the front or the rear and moves to the pressure position in the horizontal position, the locking portion of the movable member is It is possible to move from below or from above to a position where it can be locked with the locked portion of the attachment.

  In the present invention, as described above, the insertion portion for inserting and guiding the attachment attached to the flat conductor into the housing for improving the rigidity of the flat conductor is replaced with the conductor portion of the connecting portion of the flat conductor. Since the flat conductor is reinforced outside the arrangement range so that it is outside the arrangement range, and the flat conductor is exposed on both sides within the arrangement range, the receiving portion of the housing that receives the connecting portion is high. It is not required to be large, and this leads to miniaturization in the height direction of the connector. Moreover, when the connecting portion of the flat conductor is inserted into the housing, the pressing portion of the movable member is not in the pressing position, and this insertion is easily inserted with zero resistance or low resistance, so that it is inserted to the normal position. When this occurs, the time can be easily confirmed, incomplete insertion is prevented, and a situation in which the flat conductor is displaced from its normal position or inadvertently pulled out can be avoided.

The front part of the upper arm part 21 is housed in the upper part of the terminal hole 16, and the rear part is exposed to the upper open space of the receiving part 15. A turn support portion 21A that is concavely curved is formed at the lower edge of the rear end portion of the upper arm portion 21 and rotatably supports a shaft portion of a movable member 30 that will be described later. A protruding contact portion 22 </ b> A is formed on the upper edge of the rear end of the lower arm portion 22. The lower arm portion 22 is housed in a lower portion of the terminal hole 16 in the front portion and a groove portion 16A extending from the terminal hole 16 in the rear portion, but the contact portion 22A protrudes upward from the groove portion 16A.

  The connecting portion 24 has a lower edge substantially at the same level as the bottom surface of the housing, and serves for solder connection with a corresponding circuit portion of a circuit board (not shown).

  The movable member 30 is made of the same insulating material as the housing 11 and has the same width as the housing 11 as seen in FIG. The movable member 30 is supported by the rotation support portion 21A of the terminal 20 so as to be rotatable about the shaft portion 34 between the open position and the pressurization position. A pressing portion 30A that presses the connecting portion against the contact portion 22A of the terminal 20 (see FIGS. 8 and 9), and in the open position seen in FIG. A rotating arm portion 32 extending obliquely downward from the lower end of the operation portion 31 in the terminal arrangement range, and a locking portion 35 protruding downward adjacent to the width direction end portion of the rotating arm portion 32 at both ends in the width direction. (See FIG. 3).

 As shown in FIGS. 3 and 5, the operation portion 31 has a substantially T-shaped cross section, gives an arm length necessary for rotating the movable member 30 at its height, and The protruding portion toward the side forms a hooking portion 31A for hooking a finger when returning the movable member after rotation to the open position.

  As shown in FIG. 5, the rotating arm portion 32 extends toward the rear end side of the upper arm portion 21 of the terminal 20, and the rear arm side of the upper arm portion 21 is positioned at a position corresponding to the terminal 20 in the width direction. A groove portion 33 is formed so as to penetrate in the front-rear direction. A shaft portion 34 is provided in the groove portion 33 to connect the opposing inner surfaces of the groove portions, and the shaft portion 34 is supported by the rotation support portion 21A formed on the upper arm portion 21 of the terminal 20 described above. Has been.

  At both ends in the width direction of the movable member 30, an L-shape is formed backward from the tip of the arm-like portion extending downward in FIG. 1 showing the state where the movable member 30 is in the open position. A stop 35 is provided. In FIG. 3, only the locking portion 35 appears as a cross section. When the movable member 30 is tilted forward and rotated to the pressurizing position, the arm-like portion becomes horizontal, and the locking portion 35 takes a posture of protruding upward from the tip of the arm-like portion.

  The attachment 40 is made of an insulating material in the same manner as the housing, and as seen in FIGS. 1 and 2, the reinforcing portion 41 extending in the width direction of the flat conductor F, as well as seen in FIG. An arm-shaped insertion portion 42 extending forward from both ends of the reinforcement portion 41, an elastic lock arm 43 extending forward alongside the insertion portion 42, and both ends of the reinforcement portion 41 are vertically penetrated. It has an elastic arm-shaped attachment portion 45 located below the hole portion 44. When the reinforcing portion 41 is positioned so that the lower surface thereof is in contact with the upper surface of the flat conductor F, the mounting portion 45 is configured so that the mounting claws 45A of the mounting portion 45 are connected to the flat conductor F from the lower surface side of the flat conductor F. The attachment 40 is attached to the flat conductor F by this locking, and the flat conductor F is reinforced by the reinforcing portion 41. To do. Note that the attachment of the attachment 40 to the flat conductor F is not limited to locking by the attachment portion, and may be attached by sandwiching the flat conductor from above and below at the reinforcing portion 41 or by adhesion.

  The insertion part 42 has a bowl-like introduction part 42A that is tapered forward, and a bowl-like introduction part whose upper edge protrudes inward in the width direction with one step higher in the middle position of the introduction part 42A in the front-rear direction. And a locked portion 42B. The insertion portion 42 is configured to enter and house the inserted portion 19 of the housing 11 up to a predetermined advance position. When the movable member 30 is rotated to the pressurization position after reaching the predetermined advance position, The locking portion 35 of the movable member 30 rises from below to the rear position of the locked portion 42B and locks against the locked portion 42B to prevent the locked portion 42B from moving backward. To come.

  In the present embodiment, when the attachment 40 is in the half insertion position where it is not inserted by being advanced to a predetermined position, the upper surface of the locking portion 35 of the movable member 30 even if the movable member 30 is rotated to the pressurizing position. However, the movable member 30 does not reach the pressure position by contacting the lower surface of the locked portion 42B of the attachment 40 (see the two-dot chain line in FIG. 6). Therefore, it is possible to confirm that the attachment 40 is in the half-insertion position by knowing that the position of the movable member 30 is in the middle of rotation only by visually observing the movable member 30. Thus, the upper surface of the locking portion 35 of the movable member 30 forms the contacted portion 35A, and the lower surface of the locked portion 42B of the attachment 40 forms the contact portion 42B-1, With the contact part 42B-1, it can be easily determined that the attachment 40 is in the half insertion position.

  The contact portion 42B-1 is formed on the lower surface of the locked portion 42B of the attachment 40, and the contacted portion 35A is formed on the upper surface of the locking portion 35 of the movable member 30. It is also possible to provide the attachment 40 and the movable member 30 at a part different from the locking part 42B and the contacted part at a part different from the locking part 35, respectively.

  The elastic lock arm 43 enters the inserted portion 19 of the housing 11 together with the insertion portion 42. When the insertion portion 42 reaches a predetermined advance position, the flexure is released and a click feeling is generated, and the elastic lock arm 43 is provided. The front-end lock claw 43A engages with a lock recess 19A formed on the inner wall surface of the inserted portion 19 to prevent the attachment 40 from coming off.

  The connector using such an attachment 40 is used in the following manner.

  (1) First, the attachment 40 is attached to the flat conductor F. When mounting, the attachment 40 is arranged on the flat conductor F with the mounting portion 45 positioned behind the ear F1 of the flat conductor F, and then the attachment 40 is mounted on the flat conductor. Advance so that the upper surface of F slides. With the attachment claw 45A of the attachment part 45 of the attachment 40 being pressed against the lower surface of the ear part F1, the attachment claw 45A is slidably contacted to move forward and the locking hole F2 of the ear part F1. Get into. At this time, the attachment 40 has the reinforcement portion 41 in contact with the upper surface of the flat conductor F, the attachment portion 45 in contact with the lower surface of the ear portion F1, and the attachment claw 45A is engaged with the engagement hole F2 from below. While reinforcing the flat conductor F, it is firmly attached to the flat conductor F (see FIGS. 4A and 4B). Since the reinforcing portion 41 is at the same position in the front-rear direction as the ear portion F1 behind the connecting portion formed at the front end portion of the flat conductor F, the connecting portion includes any portion of the attachment. The insertion part 42 of the attachment 40 exists only outside the width direction both ends of the flat conductor F which does not exist and is outside the range of the connection part (see FIGS. 4 and 5).

  (2) Next, with the movable member 30 in the open position as shown in FIG. 5, the insertion portion 42 of the attachment 40 is connected to the insertion portion 19 of the housing 11 and the connection portion of the flat conductor F is connected to the housing 11. Insert into the receiving part 15. At that time, since the insertion portion 42A of the attachment 40 protrudes from the front end of the flat conductor F, the introduction portion 42A precedes the insertion of the flat conductor F into the receiving portion 15 and the above-mentioned insertion portion 42A. It is guided and inserted into the inserted portion 19. As the insertion proceeds, the rear portion of the insertion portion 42 from the introduction portion 42A is also inserted into the insertion portion 19, and the connection portion of the flat conductor F is also inserted into the receiving portion 15 with zero insertion force or low insertion force. When the insertion is performed to the predetermined advance position, the lock claw 43A of the elastic lock arm 43 adjacent to the insertion portion 42 is elastically released and is engaged with the lock recess 19A of the housing 11, and the lock for preventing the click is felt. It is understood that it was inserted together and inserted in a proper state. The connecting portion of the flat conductor F is located between the upper arm portion 21 and the lower arm portion 22 of the terminal 20 and is located on the contact portion 22A of the lower arm portion 22 (see FIG. 8).

  (3) After that, the movable member 30 in the open position is turned to the pressure position and rotated clockwise. Since the connecting portion of the flat conductor F and the attachment 40 are inserted to a predetermined position, the movable member 30 rotates from the state shown in FIGS. 6 to 7 to the pressure position without any interference with the attachment 40. To do. In the pressurizing position, the locking portion 35 of the movable member 30 is positioned immediately below the locked portion 42B of the attachment 40 from below (see FIG. 7). Thus, the movable member 30 that has come to the pressurizing position is rotated from the state of FIG. 8 to the state of FIG. 9 in a clockwise direction, and the connecting portion of the flat conductor F is brought into contact with the terminal 20 by the pressurizing portion 30A. Even if the flat conductor F is inadvertently pulled backward while being pressed against the portion 22A, the locking portion 35 is locked with the locked portion 42B of the attachment 40 and the flat conductor F is pulled backward. Stop going out. 8 and 9, the contact portion 22A of the flat conductor F and the terminal 20 interferes with each other. However, in actuality, the flat conductor F is slightly deflected upward and displaced at the contact portion. The contact portion 22A is displaced by the arm portion 22 being bent downward. That is, the amount of interference in the figure is the sum of both displacement amounts. The attachment 40 is prevented from coming off by locking the locking claw 43A of the elastic locking arm 43 of the attachment 40 with the locking recess 19A on the housing 11 side, but when the flat conductor F is pulled backward with a strong force. The elastic lock arm 43 is elastically bent in the unlocking direction. In contrast, the locking portion 35 of the movable member 30 is prevented from being directed by the locking portion unless the movable member 30 is returned to the open position. 35 reliably holds the locked portion 42B of the attachment 40 in a locked state, and the prevention of disconnection is strong.

  (4) Next, when the attachment 40 is in the half-insertion position, even if the movable member 30 is to be rotated to the pressurizing position, as shown by the two-dot chain line in FIG. The part 35A comes into contact with the contact part 42B-1 of the attachment 40, and the movable member 30 stops at a position in the middle of rotation that does not reach the pressure position. At this position, it is possible to confirm that the movable member 30 is in the mid-rotation position simply by visually observing the operation unit 31 of the movable member 30, so that the attachment 40 is inserted again.

<Second embodiment>
In the first embodiment, the movable member 30 is tilted forward from the open position standing upward and rotated to the pressurizing position, but in the second embodiment, in the reverse direction, that is, It is tilted rearward and rotated to the pressure position.

  In the second embodiment shown in FIG. 10, the locked portion 42B of the attachment 40 is provided so as to protrude upward at the middle portion in the front-rear direction of the insertion portion 42, and the upper surface thereof forms a contact portion 42B-1. On the other hand, the locking portion 35 of the movable member 30 is provided in a block shape at the upper end position of the operation portion 31, and on the lower surface of the locking portion 35 when the movable member 30 comes to the pressurizing position. A contacted portion 35A is formed.

  In such a second embodiment, when the flat conductor F with the attachment 40 is inserted to a predetermined advance position, the movable member 30 is tilted backward and rotated to the pressurization position. As shown in FIG. 11, the locking portion 35 of the movable member 30 descends from above and is positioned behind the locked portion 42 </ b> B of the attachment 40. Therefore, even when the flat conductor F is inadvertently pulled backward, the locked portion 42B of the attachment 40 is locked to the locking portion 35 of the movable member 30, and the flat conductor F is pulled out. There is no.

  Next, when the attachment 40 is in the half-insertion position, as shown in FIG. 12, the movable portion is moved with respect to the contact portion 42B-1 formed on the upper surface of the locked portion 42B of the half-insertion attachment 40. The movable member 30 does not rotate to the pressurization position shown in FIG. 2 but stays in the middle of the rotation without contacting the contacted portion 35A formed on the lower surface of the locking portion 35 of the member 30. This state can be easily visually confirmed at the position of the operation unit 31 of the movable member 30. In this case, the attachment 40 is inserted again.
