Description

  The present invention relates to a flexible conductor connecting connector for connecting to a flexible conductor having a plurality of contact patterns formed on an end portion of a substrate.

  Conventionally, as this type of connector for connecting a flexible conductor, for example, a connector shown in Patent Document 1 below has been proposed. This is composed of a connector housing in which a plurality of plate-like electrical connectors are arranged side by side, and a cover that is rotatably attached to the connector housing so that an opening can be made large upward. The flexible conductor placed on the mounting portion of the housing from above the portion is configured to be pressed and connected to each electrical connector by a cover that is closed and locked to the housing side. In addition, a protrusion for locking the flexible conductor is provided in the mounting portion of the connector housing, and the cover engages with the locking protrusion when the cover is closed to the mounting portion, so that the flexible conductor is placed on the mounting portion. It is the structure which provided the engaging part which can be press-maintained. The structure in which the cover is rotatably attached to the connector housing is provided with a rotation support portion that protrudes from both sides of the cover, and a fitting hole that is fitted into a fulcrum pin that protrudes from both side walls of the housing. In the mechanism for locking the cover to the housing, an engagement hole for engaging with a locking piece formed on the side wall portion of the housing is provided on the side wall of the cover. The lock mechanism of the flexible conductor is formed by forming a square hole to be fitted into a protrusion provided on the housing side in the flexible conductor itself.

  Similarly, for example, a technique shown in Patent Document 2 below has been proposed as a conventional technique. In this case, the connector is composed of a connector base and a housing. A pair of ribs are formed on both side surfaces of the connector base, and a pair of fitting holes for fitting the ribs are formed on both inner side surfaces of the housing, and the housing is rotatably attached to the connector base. The housing is formed with a pair of hook portions protruding, and a terminal pattern which is a part of the circuit pattern is exposed at the end of the FPC. A pair of openings are formed on both sides of the terminal pattern. ing. And a locking mechanism is comprised because a hook part engages with an opening. In this way, when the FPC is mounted and connected to the connector, its state is locked.

Moreover, as a prior art, for example, what is shown in the following Patent Document 3 has been proposed. In the FPC connector, the FPC does not come out, and foreign matter is not caught between the land pattern of the FPC and the contact of the housing. Specifically, the FPC connector includes a housing which is an insulator and an actuator which is connected to the housing so as to be slid up and down and slidable in the front-rear direction of the housing. The actuator supports the FPC and presses it against the housing. The FPC has a land pattern on the lower surface of the substrate, and has protruding portions on both sides of the substrate to provide ears. Hooks are formed on both side wall portions of the housing. The actuator is provided with a fixed portion. The fixing portion is an FPC ear portion that is fitted and held. The fixing portion is hooked by the hooking portion, and is tilted and slid in the front-rear direction. As for FPC, the ear | edge part is latched by the latching part of an actuator and it is hold | maintained at an actuator. The FPC moves back and forth in the housing, and the round pattern moves on the contact. Therefore, even if foreign matter adheres to either the FPC round pattern or the contact surface of the housing, it is removed by the frictional force between the round pattern and the contact surface to ensure electrical communication. .
Japanese Utility Model Laid-Open No. 5-48270 (paragraph [0006], paragraph [0007], paragraph [0012], paragraph [0013]) Japanese Utility Model Publication No. 6-84688 (paragraphs [0006] to [0009]) JP 2002-231350 A (paragraph [0017] to paragraph [0026])

  However, the flexible conductor that is adhered to the substrate and exposed on the end portion to form the contact pattern sometimes peels off from the substrate due to aging, repeated use, and the like. The peeled portion may be bent and come into contact with an adjacent contact pattern. In such a state, if a connection is made using the connectors as shown in Patent Documents 1 to 3, a short circuit accident will occur. Further, since the contact pattern is bent, the contact on the connector side may not be reliably contacted and a contact failure may occur. In the prior art, the flexible conductor is locked so that it does not come out of the connector, and even if considerations such as removing foreign matter are taken into account as shown in Patent Document 3, the short circuit accident and contact as described above are important. It has not yet been resolved to resolve defects.

  Therefore, the present invention reliably removes problems such as short-circuit accidents and contact failures due to peeling of the contact pattern in the flexible conductor connecting connector connected to the flexible conductor having a plurality of contact patterns formed on the end portion of the substrate. An object is to provide a connector for connecting a flexible conductor.

In the flexible conductor connecting connector of the present invention according to claim 1 of the present application, since the groove for accommodating the contact pattern is formed on the extension line of the contact provided on the connector base, the end of the flexible conductor is formed. The contact pattern is guided by the groove to reach the position of the contact by being inserted and pulled back to the groove portion and being pressed by the pressure contact body. Even if the contact pattern is peeled off from the flexible substrate and bent, the contact pattern is corrected and returned to its original state while being guided by the groove. Then, the corrected contact pattern is brought into contact with the contact. The flexible conductor is pressed against the connector base by the press contact body and is held by the lock portion. Therefore, even if the contact pattern is peeled off, the flexible conductor can be connected by the flexible conductor connecting connector without causing a short circuit accident, poor contact, or the like. Further, since the press contact body is rotatably attached to the connector base body by the support shaft, the contact and separation operation with respect to the press contact body connector base body can be easily performed with a simple configuration. Further, since the anti-slip surface is provided at a position facing the contact of the press contact body, the flexible conductor may be unnecessarily detached from the flexible conductor connecting connector by the anti-slip surface in the connected state. The connection state can be reliably maintained with a simple configuration that is prevented.

  Further, in the connector for connecting a flexible conductor of the present invention according to claim 2 of the present application, since the groove for accommodating the contact pattern is formed on the extension line of the contact provided on the connector base, the end of the flexible conductor is formed. The contact pattern is guided to the groove to reach the position of the contact by inserting the portion up to the groove portion and pulling it back and pressing the portion with the pressure contact body. Even if the contact pattern is peeled off from the flexible substrate and bent, the contact pattern is corrected and returned to its original state while being guided by the groove. Then, the corrected contact pattern is brought into contact with the contact. The flexible conductor is pressed against the connector base by the press contact body and is held by the lock portion. Therefore, even if the contact pattern is peeled off, the flexible conductor can be connected by the flexible conductor connecting connector without causing a short circuit accident, poor contact, or the like. Further, since the press contact body is rotatably attached to the connector base body by the support shaft, the contact operation of the press contact body with respect to the connector base body can be easily performed with a simple configuration.

  Furthermore, in the connector for flexible conductor connection according to the third aspect of the present invention, a groove for accommodating the contact pattern is formed on an extension line of the contact provided on the connector base. The contact pattern is guided to the groove to reach the position of the contact by inserting the portion up to the groove portion and pulling it back and pressing the portion with the pressure contact body. Even if the contact pattern is peeled off from the flexible substrate and bent, the contact pattern is corrected and returned to its original state while being guided by the groove. Then, the corrected contact pattern is brought into contact with the contact. The flexible conductor is pressed against the connector base by the press contact body and is held by the lock portion. Therefore, even if the contact pattern is peeled off, the flexible conductor can be connected by the flexible conductor connecting connector without causing a short circuit accident, poor contact, or the like.

  Furthermore, in the flexible conductor connector of the present invention according to claim 4 of the present application, since the groove for accommodating the contact pattern is formed on the extension line of the contact provided on the connector base, the end of the flexible conductor is formed. The contact pattern is guided to the groove to reach the position of the contact by inserting the portion up to the groove portion and pulling it back and pressing the portion with the pressure contact body.

Then, the corrected contact pattern is brought into contact with the contact. The flexible conductor is pressed against the connector base by the press contact body and is held by the lock portion. Therefore, even if the contact pattern is peeled off, the flexible conductor can be connected by the flexible conductor connecting connector without causing a short circuit accident, poor contact, or the like. Further, since the anti-slip surface is provided at a position facing the contact of the press contact body, the flexible conductor may be unnecessarily detached from the flexible conductor connecting connector by the anti-slip surface in the connected state.

  The best mode for carrying out the present invention is the embodiment described below.

An embodiment of the present invention will be described with reference to FIGS. FIG. 1 is a side view showing a connector base and a press contact body of a flexible conductor connecting connector in an embodiment of the present invention separately, and FIG. 2 is a perspective view showing a usage state of the flexible conductor connecting connector in an embodiment of the present invention. FIG. 3 is a plan view showing the connector base of the flexible conductor connecting connector in the embodiment of the present invention,

FIG. 7 is a plan view showing the flexible conductor from which the contact pattern applied to the embodiment of the present invention has been peeled off, and FIG. 8 is a plan view showing the flexible conductor connecting connector in the embodiment in the embodiment of the present invention. It is a top view which shows the state which correct | amended the malfunction by peeling of a contact pattern.

  In the figure, reference numeral 1 denotes a connector for connecting a flexible pattern conductor. The connector base 2, a press contact body 4 rotatably attached to the connector base 2 by a support shaft 3, and the press contact body 4 are locked to the connector base 2. The lock part 5 is comprised. The flexible conductor 6 is formed by exposing a plurality of contact patterns 63 on an end portion 62 of a flexible substrate 61. The exposed contact pattern 63 rises from the flexible substrate 61 by the thickness. A concave portion 7 is formed at a position facing the pressure contact body 4 of the connector base 2. The concave portion 7 is provided with a curved contact 8 for contacting the contact pattern 63. One end of the contact 8 is fixed to the connector base 2 as a fixed end 81, and the other end is exposed from the connector base 2 as a connection end 82. A groove 9 for receiving the connector pattern 63 is formed on the connector base 2 on the extension line of the contact 8. The connector base 2 is attached on the printed circuit board 10. The connection end 62 of the contact 8 is soldered to a land on the printed circuit board 10. In this way, the contact 8 is fixed at both ends and positioned in the recess 7, but is bent as a whole.

  The pressure contact body 4 is movable so as to be able to come into contact with and separate from the connector base body 2, but in a rotating state separated from the connector base body 2, there is a gap 11 into which the flexible conductor 6 is inserted between the connector base body 2 and the pressure contact body 4. It is supposed to be formed. On the other hand, the press contact body 4 is rotated in the direction of the connector base 2 and is held by the lock portion 5 in a state of being pressed on the connector base 2. The lock portion 5 includes a locking recess 51 formed in the connector base 2 and a locking claw 52 formed in the press contact body 4. Further, an anti-slip surface 12 is formed at a position facing the contact 8 on the lower surface of the press contact body 4.

  Next, the operation of the above-described configuration of the embodiment of the present invention will be described with reference to FIGS. The connection of the flexible conductor 6 by the flexible pattern conductor connecting connector 1 is achieved by bringing the contact pattern 63 into contact with the contact 8. For this purpose, first, the press contact body 4 is moved so as to take a rotational position separated from the connector base 2. In this state, a gap 12 is formed between the connector base 2 and the press contact body 4, so that the flexible conductor 6 is inserted into the gap 11 as shown in FIG. 5. This insertion is performed until the tip of the flexible conductor 6 protrudes from the flexible pattern conductor connecting connector 1. Thereafter, the pressure contact body 4 is pressed in the direction indicated by the arrow A, and the flexible conductor 6 is pulled back as indicated by the arrow B so that the contact pattern 63 is positioned on the contact 8. Thereafter, the press contact body 4 is locked to the connector base 2 by the lock portion 5 at the final position of pressing. This locking is achieved by the locking claw 52 of the press contact body 4 being locked by the locking recess 51 of the connector base 2. Therefore, the pressure contact body 4 is kept pressed against the connector base 2. By this holding, the contact pattern 63 of the flexible conductor 6 is bent and held between the contact 8 and the press contact body 4 which exhibit a resilient force. Further, the flexible conductor 6 is prevented from slipping out by a non-slip surface 12 provided on the pressure contact body 4.

  If the contact pattern 63 is peeled off from the flexible substrate 62 as shown in FIGS. 5 and 7 and is in contact with the adjacent contact pattern 63, the connection is made with the flexible conductor connecting connector 1 in this state. A short circuit accident will occur. However, in the connection work, the flexible conductor 6 is inserted into the gap 11, the tip is once protruded from the flexible conductor connecting connector 1 and pulled back, and the press contact body 4 is pressed, so that the contact pattern 63 is in the groove 9. You will be guided by. Therefore, the contact pattern 63 that has been peeled and bent is corrected as shown in FIG. By this correction, the contact pattern 63 is positioned at a normal position on the contact 8.

  According to the embodiment described above, the flexible conductor connecting connector 1 is formed with the groove 9 for holding the contact pattern 63 on the extended line of the contact 8 provided on the connector base 2. The contact pattern 63 is guided by the groove 9 to reach the position of the contact 8 by inserting and pulling back up to 9 portions and by pressing with the pressure contact body 4. Even if the contact pattern 63 is peeled off from the flexible substrate 61 and bent, the contact pattern 63 is corrected while being guided by the groove 9 and moved to the original state. Then, the corrected contact pattern 63 is brought into contact with the contact 8. The flexible conductor 6 is pressed against the connector base 2 by the press contact body 4 and is held by the lock portion 5. Therefore, even if the contact pattern 63 is peeled off and bent, the flexible conductor 6 is brought into the original state and is brought into contact with the contact 8, so that a short circuit accident and poor contact do not occur. Moreover, since the press contact body 4 is rotatably attached to the connector base 2 by the support shaft 3, the contact and separation operation of the press contact body 4 with respect to the connector base 2 can be performed only by the turning operation. Further, since the anti-slip surface 12 is provided at a position in contact with the flexible conductor 6 of the press contact body 4, the flexible conductor 6 is sandwiched between the contact 8 and the anti-slip surface 12 that exerts elasticity in the connected state. Thus, the flexible conductor connecting connector 1 is not unnecessarily disconnected.

  In the above-described embodiment of the present invention, the press contact body 4 is rotatably attached to the connector base 2 by the support shaft 3, but the press contact body 4 is linearly formed by a guide groove and a pin guided by the guide groove. The connector base 2 may be moved and moved away from it.
