Description

  The present invention relates to a board connection structure that is connected to a mating connection member such as a flexible printed circuit (FPC) or a flexible flat cable (FFC).

  The electrical connector to which the FFC as the counterpart connection member is connected includes, for example, a housing, a contact held by the housing, and an actuator for maintaining a contact state between the conductive portion of the FFC and the contact. (For example, see Patent Document 1).

  The actuator is swingably attached to the housing and can swing between an open position and a closed position. The FFC is inserted between the housing and the actuator with the actuator in the open position. When the insertion of the FFC is completed, the actuator is operated by the operator's finger or the like and displaced to the closed position, and as a result, the FFC is locked. As a result, the plurality of conductive portions of the FFC come into contact with the corresponding contacts, and the connection operation between the FFC and the electrical connector is completed.

  In the configuration described in Patent Document 1, a protruding actuator side lock portion is formed on the side portion of the actuator. Since the actuator is disposed at the closed position, the actuator side lock portion engages with the protruding housing side lock portion formed on the housing. As a result, the actuator does not need to return to the open position even when it receives an external force such as vibration or impact.

And a second engagement portion 53 that engages with the first engagement portion 52. Then, the flexible connecting member 8 is inserted between the bottom wall portion 31 of the housing 22 and the actuator 20 so that the engagement between the first engaging portion 52 and the second engaging portion 53 is prevented. The actuator 20 is configured to prevent the actuator 20 from reaching the temporary holding position A3.

  The first engaging portion 52 constitutes a part of the housing 22. The first engagement portion 52 is disposed so as to avoid a region of the housing 22 through which the flexible connection member 8 passes. Specifically, the first engaging portion 52 is provided on the bottom wall main body 36 of the housing 22. The first engaging portions 52 are disposed at both ends of the bottom wall main body 36 in the width direction X1.

  More specifically, the bottom wall body 36 of the housing 22 is formed on both sides in the width direction X1 with respect to the passage portion through which the flexible connecting member 8 passes, and the flange portion 54 protrudes toward the actuator 20 with respect to the passage portion. , 54. The flange portions 54, 54 extend from the front end edge 36a of the bottom wall main body 36 toward the back portion 33 side along the length direction Y1. The upper surfaces of the flange portions 54 and 54 are flat surfaces orthogonal to the thickness direction Z1. Thereby, the collar parts 54 and 54 have the opposing part which opposes the base end part 20a of the actuator 20, and the thickness direction Z1. This facing portion includes the first engaging portion 52.

  The bottom wall body 36 of the housing 22 is provided with retaining portions 56, 56 adjacent to the flange portions 54, 54. Each retaining portion 56, 56 is a block-shaped portion formed on the front end edge 36 a side of the bottom wall portion 31 of the corresponding flange portion 54, 54. Each retaining portion 56, 56 protrudes upward from the bottom wall main body 36 and can be engaged with the corresponding ear portion 14 of the insulating portion 12 of the flexible connecting member 8. This prevents the flexible connecting member 8 from coming off the connector 11.

  The second engagement portion 53 is formed integrally with the actuator 20. In this embodiment, the 2nd engaging part 53 is formed of the convex part (projection-like part). The second engagement portion 53 is provided at the proximal end portion 20 a of the actuator 20. In the present embodiment, the second engaging portion 53 is disposed at both ends of the actuator 20 in the width direction X1 and is adjacent to the shaft portions 42 and 42. In the width direction X <b> 1, the position of each first engagement portion 52 is aligned with the position of the corresponding second engagement portion 53. One side surface 53a of the second engagement portion 53 is disposed so as to face the first engagement portion 52 in the thickness direction Z1 when the actuator 20 is located at the temporary holding position A3. In the present embodiment, the temporary holding position A3 is substantially the same as the closed position A2, but is a position where the actuator 20 is slightly lifted from the bottom wall 31 compared to the closed position A2.

  One side surface of the second engaging portion 53 has an inclined portion 53a and a flat portion 53b.

  The inclined portion 53 a is a surface that is inclined so as to approach the first engaging portion 52 as it approaches the shaft portions 42, 42. The inclined portion 53a is continuous with the flat portion 53b. The flat portion 53 b is a flat surface provided as a portion that is in direct contact with the first engagement portion 52, and can be in surface contact with the first engagement portion 52.

  When the actuator 20 is in the temporary holding position A3, the actuator 20 is arranged substantially in parallel with the bottom wall portion 31, as shown in FIGS. At this time, the flat portion 53b of each second engagement portion 53, 53 is in contact with the corresponding first engagement portion 52, 52. At this time, the height (projection amount) of the second engagement portion 53 from the actuator 20 is set to a predetermined value. Thereby, each 2nd engaging part 53 and 53 is contacting with the corresponding 1st engaging part 52 and 52 in the pressurization state. Thereby, each 2nd engaging part 53 and 53 engages with the corresponding 1st engaging part 52 and 52 with sufficient engaging force in a surface contact state. As a result, the actuator 20 is supported at both ends by the first engagement portion 52 in the width direction X1. Therefore, the actuator 20 is held in a stable posture with respect to the housing 22 at the temporary holding position A3, and displacement relative to the housing 22 is restricted. That is, the actuator 20 is held at the temporary holding position A <b> 3 by the engagement between the first engagement portion 52 and the second engagement portion 53 of the temporary holding mechanism 51.

  Next, the operator displaces the actuator 20 from the temporary holding position A3 to the open position A1 (see FIG. 6) by displacing the actuator 20 around the shaft portions 42 and 42. And from this state, while inserting the ear | edge parts 14 and 14 of the other end part 8b of the flexible connection member 8 between the retaining parts 56 and 56 and the fitting part 34, the other end part 8b is made into the bottom wall main body 36. Along the top surface.

  Next, the operator inserts the other end portion 8 b of the flexible connection member 8 between the bottom wall main body 36 of the housing 22 and the actuator 20. As a result, as shown in FIGS. 8 and 9, the flexible connecting member 8 applies a load to the actuator 20 to push up the actuator 20 to one side in the thickness direction Z1. As a result, the actuator 20 is elastically deformed with the shaft portions 42 and 42 as fulcrums, whereby the first engagement portion 52 is separated from the second engagement portion 53. That is, the temporary holding function of the actuator 20 by the temporary holding mechanism 51 is released.

  With this operation, the flexible connecting member 8 displaces the actuator 20 from the open position A1 to the closed position A2. Thereby, as described above, the second contact portion 25 of each contact 21 is in pressure contact with the corresponding conductive portion 13 of the flexible connection member 8, and electrical connection between the flexible connection member 8 and the connector 11 is achieved. Is done.

  As described above, according to the connector unit 2, the actuator 20 is disposed at a position recessed from the first side surface 15 with respect to the thickness direction Z <b> 1 of the LED substrate 10 when the actuator 20 is located at the closed position A <b> 2. Thereby, the actuator 20 does not protrude from the first side surface 15 of the LED board 10, and the connector unit 2 (board connection structure) including the actuator 20 and the LED board 10 as a whole can be made thinner.

  Further, according to the connector unit 2, with respect to the thickness direction Z1, more than half of the actuator 20 has a virtual first plane P1 including the first side surface 15 and a virtual side including the second side surface 16 at the closed position A2. It arrange | positions in the space S2 pinched | interposed by the 2nd plane P2. According to this configuration, the connector unit 2 can be made thinner.

  Further, according to the connector unit 2, the notch 18 is formed in the one edge 10 a of the LED substrate 10, and the actuator 20 is disposed in the notch 18. According to this configuration, a part of the space substantially occupied by the LED substrate 10 in the thickness direction Z1 of the LED substrate 10 can be used as a space for arranging the actuator 20. As a result, the connector unit 2 can be further reduced in thickness and size.

  Further, according to the connector unit 2, the shaft portions 42, 42 of the actuator 20 are arranged to face the edge portion 18 a of the notch portion 18 of the LED substrate 10. According to this structure, the connector 20 can be further reduced in thickness by disposing the actuator 20 near the edge 18a.

  Further, according to the connector unit 2, the housing 22 has receiving portions 37 and 37 that can be received by the second side surface 16 of the LED substrate 10. According to this configuration, the receiving portions 37 and 37 of the housing 22 are disposed on the second side surface 16 of the LED substrate 10 opposite to the first side surface 15 where the actuator 20 is adjacently disposed. Thereby, the thickness by the side of the 1st side 15 among connector units 2 is not increased. Therefore, the housing 22 can be more firmly fixed to the LED board 10 while realizing a reduction in the thickness of the connector unit 2. In addition, since the receiving portions 37 and 37 are not arranged on the first side surface 15 side, which is the side surface of the LED substrate 10 close to the actuator 20, when the actuator 20 is operated by a finger of an operator, the receiving portions 37 and 37 are provided. No need to get in the way. In particular, when the LED substrate 10 is disposed in a thin space between the light guide plate 7 and the chassis 4, the effect of improving the operability of the actuator 20 due to the receiving portions 37 and 37 not interfering is remarkable.

  Further, according to the connector unit 2, the direction Z11 in which the mounting surface 19a on which the housing 22 of the connector 11 is mounted is different from the displacement direction B1 when the actuator 20 is displaced from the closed position A2 to the open position A1. Thereby, for example, when the worker operates the actuator 20 with a finger or the like, it is possible to suppress the mounting unit 19 from coming into contact with the finger or the like. Therefore, when the operator operates the actuator 20, the mounting unit 19 does not get in the way. That is, more space for operating the actuator 20 can be secured. Thus, by securing a larger space for operating the actuator 20, even when a large number of parts including the connector unit 2 are arranged in the thin (narrow) space S <b> 1, an operator or the like can easily operate the actuator 20. Can be operated.

  Further, according to the connector unit 2, the actuator 20 is formed to have a length equal to or less than half the length of the housing 22 in the facing direction (length direction Y <b> 1) in which the contact 21 and the flexible connection member 8 face each other. According to this configuration, when the actuator 20 is opened from the closed position A2 to the open position A1, the protruding amount of the actuator 20 from the LED substrate 10 can be remarkably reduced. Thereby, even when the space for inserting the operator's finger or the like for operating the actuator 20 is narrow, the actuator 20 can be reliably displaced from the closed position A2 to the open position A1 by the finger or the like.

  Moreover, according to the connector unit 2, the actuator 20 is arrange | positioned in the front end side of the direction which goes to the flexible connection member 8 side from the housing 22 among opposition directions (length direction Y1). According to this configuration, the distal end portion farthest from the shaft portions 42, 42 of the actuator 20 is disposed at the distal end side edge portion of the housing 22. As a result, even if the size of the actuator 20 is small, an operator can easily operate the actuator 20 with a finger or the like.

  Further, according to the connector unit 2, the reinforcing tabs 23 and 23 are disposed at both ends in the width direction of the housing 22 and are fixed to the mounting portion 19. According to this configuration, when the actuator 20 is displaced between the open position A1 and the closed position A2 by an operator's finger or the like, the reinforcing tabs 23 and 23 do not become an obstacle.

  Further, according to the connector unit 2, the actuator 20 is disposed in the notch 18 of the LED substrate 10. According to this configuration, the connector 11 is arranged so as to be aligned with the edge 18 a of the notch 18 of the LED substrate 10. Thereby, the protrusion amount of the connector 11 from the LED board 10 can be made smaller. Therefore, even when the parts are densely arranged around the actuator 20, more space for operating the actuator 20 can be secured.

  Further, according to the electrical connector 11, even when the flexible connection member 8 is not connected to the connector 11, the actuator 20 is held by the temporary holding mechanism 51 at the temporary holding position A <b> 3 that is a fixed position with respect to the housing 22. Is done. Therefore, when the connector 11 is transported as a single item, the actuator 20 can be restrained from being displaced with respect to the housing 22 by vibration or the like. Further, by inserting the flexible connection member 8 between the housing 22 and the actuator 20, the engagement between the first engagement portion 52 and the second engagement portion 53 of the temporary holding mechanism 51 is prevented. Thereby, when the flexible connection member 8 is inserted between the housing 22 and the actuator 20, it is possible to prevent a resistance force due to the engagement between the first engagement portion 52 and the second engagement portion 53 from occurring. it can. Therefore, at this time, the actuator 20 can be more reliably displaced from the open position A1 to the closed position A2 without being interrupted by the temporary holding mechanism 51.
