Description

The present invention is a flat and flexible FPC (Flexible.
The present invention relates to an FPC connector for electrically connecting a printed circuit).

  As an FPC connector, when inserting an FPC, it can be inserted with a low insertion force without receiving contact pressure from the contact, and after inserting the FPC, the contact with the contact with a predetermined contact pressure makes it possible to obtain a stable electrical connection. An insertion force (hereinafter referred to as ZIF) structure is known (see, for example, Patent Document 1, hereinafter referred to as a known example A).

  According to this known example A, the contact for connecting (connecting) the FPC has an elastic contact portion on one of the two pieces facing each other in a substantially U shape, and a rotation support portion on the other piece. When the pressure member supported rotatably by the rotation support portion is rotated by a predetermined amount, the pressure portion of the pressure member presses (pressurizes) the FPC from the upper surface side. It is supposed that the connection between the FPC and the contact is maintained without being easily opened.

  The following ZIF structure is also known (see, for example, Patent Document 2, hereinafter referred to as a known example B).

According to this known example B, conductor exposed portions (connecting portions) are formed on both sides of the FPC, and a pair of conductor exposed portions are provided on both sides of the connector. Pairs of contacts (contacts) to be electrically connected to the exposed portions are provided, and the connector generates contact pressure between the contacts and the exposed conductor portions. A pair of fixing levers that can be opened and closed and press the exposed conductor of the FPC against the contact are provided. With these configurations, the number of exposed conductors can be increased, and downsizing is possible even in the case of multipolarization (increasing the number of contacts).
JP-A-7-142130 JP 7-65914 A

  In electronic devices that are becoming smaller and more functional, FPC connection connectors that are frequently used as internal wiring members can be reduced in size and multipolar while maintaining connection reliability. It is desirable to have a form that can be achieved.

  In the conventional example as in the known example A, contacts are arranged in a line at a plurality of positions in the longitudinal direction at equal pitches in the housing, and the contacts are soldered to the circuit board (solder connection). A tail part (connecting part) for caulking is provided. In such a form, in order to increase the number of poles, it is only necessary to extend the housing in the longitudinal direction and increase the number of locations where the contacts are arranged. However, in order to meet the needs of miniaturization (low profile), the height (thickness) of the housing is limited, and if the housing is extended in the longitudinal direction under this limitation, The degree of warping and twisting (due to shrinkage during resin molding and thermal effects during soldering) increases, and the flatness of each tail part relative to the soldering surface on the circuit board (variation in the height of the lower edge of each tail part) Degree) and soldering failure may occur (the solder does not reach the tail).

  Also, in the fixing function between the connector and the circuit board, it is only necessary to solder only the tails arranged in a line at the rear of the housing to the circuit board (particularly, the FPC inserted into the opening and connected to it is pulled up carelessly). If there is a risk that the connector will float from the FPC insertion side and the soldered part may be peeled off), the fixing strength will be insufficient. The form is reinforced by soldering together with the tail part. However, adding a metal fitting as a used part increases part cost and assembly cost.

  Further, in the conventional example as in the known example B, the substantially U-shaped pressurizing member (fixing lever) uses the shaft formed on both sides of the housing (insulating block) as a fulcrum and pressurizes between the fulcrum. The part (pressing part) is configured to pressurize (press) the upper surface of the FPC, but when the pressing part, which is an intermediate part between the fulcrums, receives a force from below (a reaction force against the applied pressure), it moves upward. The structure tends to bend and float, and the contact pressure of the contacts (particularly the contacts arranged in the central portion) may decrease, resulting in poor connection. This failure phenomenon is said to increase as the number of contacts increases (because the distance between the fulcrums increases and the deflection further increases). The purpose of the conventional example cannot be achieved (the pressurizing member needs to be enlarged to resist an increase in reaction force due to multipolarization). In addition, the wiring pattern (printed wiring) routed between the exposed conductor portions formed on both sides of the FPC has an increased or decreased number of wires corresponding to the number of exposed conductor portions. When the number of exposed conductors is increased, the number of wirings also increases. Therefore, it is necessary to secure the wiring area by expanding the lateral width of the FPC (when the wiring pitch is constant), and the width of the housing is also increased. It becomes necessary to widen, and the realization of miniaturization of the connector is hindered.

  Accordingly, an object of the present invention is to solve the problems of the prior art as described above, and to provide an FPC connector that can maintain connection reliability and can realize a small multi-pole and a low cost. There is to do.

  In order to achieve the above object, an FPC connector according to claim 1 is an electrical connector for electrically connecting an FPC in which a plurality of conductor exposed portions are arranged side by side on the side of a wiring end extending in the front-rear direction. The housing has a housing portion that opens upward so that the wiring end portions can be accommodated one above the other. The housing includes an elastic contact piece, a support piece arranged above the elastic contact piece, and the two pieces. The left and right contactors in the housing are arranged in such a manner that a plurality of contacts each having a base end portion that integrally connects the base ends of the housing portions are divided in the left-right direction of the housing portion and the two pieces are opposed to each other. And the pair of pressure members are held by the housing in correspondence with each of the arrangement parts of the left and right contacts, and in the accommodated state. , Left and right The side portion of the overlapping lower wiring end portion is positioned above the elastic contact piece in one arrangement group of the contactors arranged in a row, and the upper side of the elastic contact piece in the other arrangement group of contacts is The side of the overlapping upper wiring end is positioned, and the pressure member intervenes between the positioned side of the wiring end and the support piece to elastically contact the side of the wiring end A pressurizing part that presses against the piece is provided.

  In this manner, a plurality of contacts (preferably formed from a conductive elastic member such as a copper alloy for springs) are divided into left and right (preferably arranged in equal left and right directions) so that the two pieces are oriented. The arrangement arranged so as to face each other (preferably symmetrically) is in contact with the arrangement arrangement only in one row (on the condition that the arrangement pitch is the same) (on the condition that the longitudinal dimension of the arrangement portion is equal). It is possible to increase the number of elements arranged (multi-polar), and compared to a single-row elongated structure during molding of the housing or soldering mounting as a connector (Relatively) warpage and twisting are less likely to occur.

  Further, since the arrangement part of the left and right contacts in the housing is integrally connected at the bottom part of the housing part, the connection part located in the middle of the arrangement part of the left and right contact parts is used for suction conveyance in automatic mounting. It can be used as an effective adsorption surface (easy to balance the left and right weights).

  Further, when the connector is fixed to the circuit board, the contacts arranged in the left and right arrangement parts integrally connected (preferably from the base end part so as to face the outside of the housing in the arranged state) With an extended soldering tail, the tail can be soldered and fixed at left and right (preferably symmetrically arranged) locations on the housing Can be easily obtained (without relying on auxiliary parts such as reinforcing metal fittings).

  In addition, in the state where the side portion of the wiring end is positioned above the elastic contact piece that is integrally connected to the support piece (substantially U-shaped spring structure), the side portion of the wiring end portion The configuration in which a pressure part is interposed between the support piece and the support piece (substantially to widen the gap) to press the side of the wiring end against the elastic contact piece is Since the pressurizing part is urged by the support piece of the contactor, even when the number of contactors is increased (multipolar), the contact pressure of the contact part between the elastic contact piece and the side part is reduced. However, the contact pressure of the contact portion can be arbitrarily set (for example, by arbitrarily setting the thickness of the pressurizing portion).

  Furthermore, the wiring end (preferably in the FPC prepared with two wiring ends symmetrical in plan view of both outer shapes and conductor exposed portions) (preferably in the accommodated state) The upper wiring end and the lower wiring end (except for the respective side portions overlap each other) are stacked one above the other, and the upper and lower wiring end portions are arranged side by side. The configuration in which each of the contactors is positioned above the elastic contact piece (substantially, the conductor exposed portion is above the tip of the elastic contact piece) is configured to accommodate only a single wiring end (upward It is possible to secure a wide wiring area of the wiring pattern (routed from the conductor exposed portion) in the accommodating portion (under the condition that the area of the accommodating portion in view is the same), and (arrangement pitch of the wiring pattern) In the same condition It can increase the number of wiring wiring pattern.

  According to claim 2, the pressurizing member includes a substantially plate-like operation part extending from the pressurization part, and the operation part has a predetermined position close to the bottom of the housing part and an open position separated from the predetermined position. A space that is held by the housing so as to be moved between and is pressed when the operating portion is in a predetermined position, and in this state, a space that partially accommodates the overlapping upper wiring end portion below the operating portion. The part is formed. In this configuration, when the upper wiring end portion and the lower wiring end portion are accommodated so as to overlap each other, the lower wiring end portion is pressed against one of the left and right contacts. When entering the state, let the overlapping part close to the side of the lower wiring end at the upper wiring end (close to the pressure part pressing the side of the lower wiring end) escape into the space This may occur when the space portion is not formed (a part of the upper wiring end abuts the lower surface of the pressure member), and the adverse effect on the pressure by preventing the intervention of the pressure portion. Lost.

  According to the third aspect, the wall portion rising from the bottom portion of the housing portion is provided on both ends of the housing portion in the front-rear direction (longitudinal direction) orthogonal to the left-right direction, and the front wall portion and the rear end side thereof are provided. At least one of the wall portions is cut out at the top to form an opening that opens upward, and these wall portions (preferably facing the wall portions on the front end side and the rear end side). The dimension between the inner surfaces is set to be slightly larger than the dimension in the width direction of the side portion that is the front-rear direction in the accommodated state) When the wiring end is accommodated, the front-rear direction in the accommodation portion Further, it is possible to restrict the movement of the wiring end portion to the FPC, and further, by forming the opening portion, the FPC is partially engaged with the opening portion (preferably through the opening portion in the accommodated state). Extend further from the wiring end as Since the wire extension part and the projecting part are provided and the wiring extension part and the projecting part and the opening are engaged with each other, the movement of the wiring end in the left-right direction in the housing part can be restricted, so that the elastic contact It becomes easy to increase the positioning accuracy when positioning the side portion (substantially, the conductor exposed portion) of the wiring end portion above the piece.

  As described above, the FPC connector of the present invention can realize a small size and a low cost while maintaining connection reliability even if it is multipolar.

  Hereinafter, embodiments of the present invention will be described with reference to FIGS. 1 to 7 of the accompanying drawings. FIG. 1 shows an embodiment of an FPC connector of the present invention and an embodiment of an FPC connected to the FPC connector. FIG. 2 shows a wiring end portion of the FPC on one side (conductor exposed portion arrangement surface). It is the top view seen from the side.

  As shown in FIG. 1, in the FPC connector 1, a housing 10 formed of an insulating resin includes an accommodating portion 11 that opens upward (upward in FIG. 1), and on the left side (in the diagonally upper left direction in FIG. 1). The first contactor arrangement portion 13 that arranges the contacts 2 in the longitudinal direction (the direction extending from diagonally upper right to diagonally lower left in FIG. 1) is arranged on the right side (diagonal lower right direction in FIG. 1) of the accommodating portion 11. The second contact arrangement portion 14 is arranged in a symmetrical arrangement with the first contact arrangement portion 13 and similarly arranges the contacts 2 in the longitudinal direction. Further, on the first contactor arrangement part 13 side and the second contactor arrangement part 14 side, a pair of pressurizing members 3 each having a plate-like operation part 32 are respectively projected on both end sides in the longitudinal direction. The portion 38 is incorporated so as to engage with the holding portion 15 of the housing 10.

  2A shows the first wiring end 40a side, and FIG. 2B shows the second tip end 40b side. In FIGS. 1 and 2, the longitudinal direction (in FIG. 1) is shown. The FPC 4 in a form extending obliquely from upper right to obliquely lower left, and in the vertical direction in FIG. 2, has a first wiring end 40a that is substantially rectangular in plan view, and a second wiring end that is symmetrical to the first wiring end 40a. 40b, and a conductor exposed portion 42 (preferably, the conductor foil is subjected to corrosion resistance plating) is disposed on one side 43a of the side portion 41a along the side edge of the first wiring end portion 40a. The conductor exposed portions 42 are also arranged on the one side 43b of the side portion 41b along the side edge of the second wiring end portion 40b, and the arrangement pitch corresponds to the arrangement pitch of the contacts 2 (shown in FIG. 1). is doing. Further, on one side 43a, 43b, a cover material 48 (preferably a plate material excellent in insulation such as a polyimide film) is bonded to a portion excluding the side portions 41a, 41b, and the back side thereof A reinforcing plate 49 (preferably made of a rigid material such as a resin plate or a metal plate) is bonded to the plate.

  Further, a wiring extension 50 extending in the longitudinal direction (upward in FIG. 2) from the wiring end portions 40a and 40b and a protruding portion 51 extending in the opposite direction are provided in the housing 10 (shown in FIG. 1). Further, the wall 18 on the front end side and the wall 19 on the rear end side of the housing 10 are connected to the side portions 41a and 41b (with the side portions 41a and 41b fitted between the wall portions). Is a means for ensuring the horizontal positioning of the wiring end portions 40a and 40b housed in the housing portion 11 together with both end portions in the longitudinal direction, and exposing the conductors disposed on the side portions 41a and 41b. The reliability of the connection between the portion 42 and the contact 2 is enhanced. In the present embodiment, the FPC 4 has a configuration in which the wiring extension 50 is provided only on one side in the longitudinal direction (upward in FIG. 2). However, the embodiment is not limited to this configuration. It may be arranged on the other side in the longitudinal direction (downward in FIG. 2) (in place of the protruding portion 51) (wiring extended in both directions). Further, the FPC 4 is connected to the wiring end 40a and the wiring end 40b at an extension (not shown) further extending from the wiring extension 50 (in other words, the wiring end 40a and the wiring end 40b are The wiring end portion 40a and the wiring end portion 40b are formed in different FPCs (the wiring end portions of the two FPCs are integrally connected). ).

  3 to 6 are cross-sectional views showing a state in which the wiring end portions 40a and 40b are accommodated in the FPC connector 1 shown in FIG. 1 and further pressed, and FIG. 3 and FIG. FIG. 5 shows a state in which the operating unit 32 is between the open position and a predetermined position, and FIG. 6 shows a state in which the operating unit 32 is in the predetermined position.

  In FIG. 3, the left and right sides of the elastic contact piece 21 and the support piece 22 that are press-fitted into the left and right holding holes 17 so as to face each other and are held in the housing 10 and arranged in such a direction as to face each other. The contact 2 has a protruding contact portion 26 provided on the distal end side 24 of the elastic contact piece 21 positioned below the support piece 22 (downward in FIG. 3) so as to protrude into the accommodating portion 11. The elastic contact piece 21 is set to be elastically displaced in a direction in which the distal end side 24 bends downward when pressure is applied to the contact portion 26 from above (upward in FIG. 3). A tail portion 29 extending outward from the base end portion 23 (both left and right in FIG. 3) is a connecting means for soldering to a circuit board (not shown).

  The pressurizing member 3 is provided on the distal end side 25 of the support piece 22 so that the operating portion 32 rotates between a predetermined position approaching the bottom portion 12 of the housing portion 11 and an open position separated from the predetermined position. The inner surface of the rotation groove portion 37 engaged with the rotation support portion 28 is easily detached from the rotation support portion 28 during rotation. It is arcuate). In the state where the plurality of contacts 2 are arranged in the contact arrangement portions 13 and 14, the rotation support portions 28 are arranged in a comb-teeth shape to form a shaft, and the rotation of the pressure member 3 is substantially performed. It has a shaft function. In addition, the engagement form of the rotation support part 28 and the rotation groove part 37 is not restricted to this form, and the uneven relationship may be reversed.

  In FIG. 3, the first wiring end portion 40a is guided between the two tip end sides 24, 25 with the conductor exposed portion 42 facing downward (the side portion 41a is on the first contactor arrangement portion 13 side). It is in a state of being accommodated in the accommodating portion 11 (through a process in which the portion excluding the side portion 41a is further dropped toward the bottom portion 12). In this state, the conductor exposed portion 42 is positioned above the contact portion 26 (as described above, the engagement relationship between the wiring extension portion 50 and the protruding portion 51 and the opening portion 16, the wall portions 18 and 19 and the side portions. 41a is also set as a setting requirement).

  In FIG. 4, the second wiring end portion 40 b overlaps the upper side of the first wiring end portion 40 a previously accommodated in the accommodating portion 11 (with the conductor exposed portion 42 facing downward) (the side portion 41 b is the second end portion). The receiving portion is guided and inserted between the two tip end sides 24 and 25 on the contact arrangement portion 14 side, and the portion excluding the side portion 41b is dropped toward the bottom portion 12). 11 shows a state of being housed. In this state, the exposed conductor portion 42 is positioned above the contact portion 26 also in the second wiring end portion 40b (the above-described engagement relationship between the wiring extension portion 50 and the protruding portion 51 and the opening portion 16). The engagement relationship between the wall portions 18 and 19 and the side portion 41b is also set as a setting requirement).

  FIG. 5 shows a state in which the pressurizing unit 31 having a thicker cross-sectional shape than the distal end portion 33 starts to come into contact with the upper surfaces of the side portions 41a and 41b in the process of rotating (moving) the operation unit 32 toward a predetermined position. Indicates the state. Thereafter, as the rotation proceeds, the side portions 41a and 41b are brought into contact with each other (the pressing portion 31 is hardly lifted because the rotation groove portion 37 is engaged and supported by the rotation support portion 28). On the other hand, it can be seen that the pressing force (strictly, the component force in the downward direction) of the pressurizing unit 31 starts to act.

  FIG. 6 shows a state in which the operation unit 32 is in a predetermined position close to the bottom 12 of the storage unit 11. In this state, the protruding portion 34 of the pressurizing unit 31 is located above the contact unit 26 from the base end 23. It has entered a position that is slightly closer to the direction. This state in which the projecting portion 34 exceeds the axis connecting the rotation support portion 28 and the contact portion 26 is a state in which the pressing portion 31 is difficult to return to the direction before the intervention. Further, the side portions 41a and 41b are pushed downward by the trajectory of the projecting portion 34, and the contact portion 26 is pushed down by the amount of displacement relative to the downward displacement amount of the side portions 41a and 41b. It can be seen that the repulsive force of the elastic contact piece 21 acts on the contact portion between the side portions 41 a and 41 b (substantially, the conductor exposed portion 42) and the contact portion 26. This action is caused when the pressurizing unit 31 is interposed between the front end side 25 of the support piece 22 and the front end side 24 of the elastic contact piece 21, and the pressurizing unit 31 is urged by the front end side 25 of the support piece 22. This is realized because the side portions 41a and 41b are sandwiched between the pressurizing portion 31 and the distal end side 24 of the elastic contact piece 21, and are individually (dynamically) acted at each contact point. It is what you are doing. Therefore, this configuration does not cause connection failure due to a decrease in contact pressure (particularly due to bending of the pressurizing portion that occurs in the case of multipolarization), which is a problem in the conventional example as in the known example B.

  Further, in FIG. 6, a space portion 39 is formed below the operation portion 32, and a space portion 39 having an inclined surface 36 inclined upward from the lower surface edge portion 35 of the pressurizing portion 31 is formed. A left side portion (a portion excluding the side portion 41b) of the wiring end portion 40b overlapping the upper side is accommodated. In this form, when the side portion 41a of the lower wiring end portion 40a enters the pressed state with the lower elastic contact piece 21 (of the contactor 2 arranged in the first contactor arrangement portion 13), The overlapping portion 45 on the left side of the wiring end portion 40b (close to the pressing portion 31 that presses the lower side portion 41a and the lower side portion 41a) escapes into the space portion 39, and such a space portion Is not formed (in the form as in the known example A in which there is no lower surface edge portion 35 of the pressurizing unit 31 and the lower surface of the pressurizing unit 31 and the lower surface of the operation unit 32 are in a flat shape). The adverse effect on the pressure (which is caused by the overlapping portion 45 coming into contact with the lower surface of the operation unit 32 and preventing the operation unit 32 from rotating to a predetermined position) is eliminated.

  3 to 6, the first wiring end portion 40a is first accommodated in the accommodating portion 11, and then the second wiring end portion 40b is overlapped upward. The end portion 40b may be accommodated in the accommodating portion 11 first, and then the first wiring end portion 40a may be stacked upward (that is, the wiring end portions 40a and 40b may be installed in any order first). However, even in this case, in order not to adversely affect the above-described pressing, a clearance somewhat larger than the thickness of the inclined surface 36 and the wiring end is provided on the lower surface side of both the pair of left and right pressure members 3. A space 39 is formed below the left and right operation units 32. In addition, it can also be comprised so that any one of the 1st wiring end part 40a and the 2nd wiring end part 40b may be connected and used, for example, in the model (function) of the apparatus in which this FPC connector is used. Accordingly, either one of the first wiring end portion 40a and the second wiring end portion 40b may be selected and connected, or both may be connected. Further, the notch 30 that is a partial space portion that is alternately provided by offsetting the left and right operation portions 32 in the front-rear direction is used when the operation portion 32 is returned to the open position (by inserting a fingertip or the like into the space portion). This is to make it easier to lift (hang) the tip of the operation unit 32.

  FIG. 7A is a plan view for explaining an example of a wiring circuit of the first wiring end 40a, and FIG. 7B is a plan view for explaining an example of a wiring circuit of the second wiring end 40b. For the sake of clarity, the cover material 48 shown in FIG. 2 is omitted. 7A, the wiring circuit basically includes a conductor exposed portion 42 disposed on the side portion 41a and a plurality of wiring patterns 53 connected to the wiring extension portion 50 from each of the conductor exposed portions 42. The conductor exposed portion (upper side in FIG. 7) is changed to a conductor exposed portion 52 having a wide pattern width. The pattern width of the wide conductor exposed portion 52 is set to a dimension such that two adjacent terminals on the end side (shown in FIG. 1) of the arranged contacts 2 (shown in FIG. 1) come into contact with each other. The wiring pattern is also wide, and the conductor resistance of this portion is relatively low (so that it is suitable for a power supply circuit and a ground circuit). In addition, another circuit layer (for example, for grounding) is provided on the back surface of the surface where the conductor exposed portion 42 is provided, and is selectively connected to the conductor exposed portions 42 and 52 and the wiring pattern 53 (through holes or the like). Transmission characteristics may be improved.

  In FIG. 7B, the form is symmetrical with the wiring circuit example shown in FIG. The symmetrical wiring end portions 40a and 40b are accommodated in such a manner that the wiring regions (regions excluding the side portions 41a and 41b) of the respective wiring patterns 53 overlap each other (as shown in FIG. 6). The configuration accommodated in the portion 11 is wider than the configuration in which only a single wiring end portion is accommodated (because of the upper and lower double structure) in the accommodation portion 11 (because of the double upper and lower structures) (this embodiment Therefore, it is possible to increase the number of wirings of the wiring pattern 53 in the accommodating portion 11, and to cope with the increase in the conductor exposed portion 42 due to multipolarization.

  In this embodiment, the first contactor array part 13 and the second contactor array part 14 are formed so as to be integrated with each other at the bottom part 12, but the present invention is limited to this. Instead, the first contactor array part 13 and the second contactor array part 14 are formed separately and then joined (for example, using a method such as ultrasonic fusion) and integrated. Even things can be used. In this embodiment, the pressurizing member 3 is rotated and the pressurizing unit 31 is intervened. However, the pressurizing unit may be moved horizontally to intervene. Furthermore, even if the FPC to be accommodated is a thin wiring member such as a multilayer wiring board incorporating a very thin IC chip, it can be applied.
