Description

  The present invention relates to a connector for connecting a flat conductor such as an FPC (flexible board) or a flat cable to a circuit board or the like, and a manufacturing method thereof.

  2. Description of the Related Art Conventionally, there is known a connector 10 that connects a flat conductor 16 such as an FPC or a flat cable to a circuit board or the like as disclosed in Patent Document 1 and Non-Patent Document 1 below. As shown in FIGS. 10 (a) and 10 (b), such a conventional connector 10 has two types of terminals 12, 13 having different shapes alternately aligned in the width direction on a housing 14 made of an insulating synthetic resin. A plate-like pressing member 15 that is rotatably engaged with the housing 14 and the terminals 12 and 13 is provided. The terminals 12 and 13 have receiving spaces 12a and 13a for receiving the flat conductor 16, respectively. When the flat conductor 16 is inserted into the receiving spaces 12a and 13a, the terminals 12 and 13 are connected to the front and back surfaces of the terminals. The portions face each other, and the contact portions 12 b and 13 b are brought into contact with the contact portion of the flat conductor 16 to connect the flat conductor 16 and the connector 10.

  As shown in FIG. 10 (see Non-Patent Document 1), the conventional connector 10 has an inverted U-shaped shaft support portion 12c so that one terminal 12 engages with the rotation shaft 15a of the pressing member 15. Since the other terminal 13 is not provided with a configuration like a shaft support portion, the pressing member 15 is supported only by the terminal 12 or is further provided with a shaft support portion (provided on the housing 14). It will be supported by a shaft (not shown).

  However, the terminals 12 and 13 are very thin in order to meet the recent demand for connector miniaturization. For this reason, when the pressing member 15 is supported by only one terminal 12 or is pivotally supported by the housing 14, the force pressing the terminal against the flat conductor 16 becomes weak, which may cause a contact failure.

  Further, the conventional connector 10 is formed by assembling the press members 15 separately molded after the terminals 12 and 13 are assembled in the housing 14. Here, the shaft support portion 12c of the terminal 12 has an inverted U-shape, and if a strong downward force is applied to the pressing member 15, the pressing member 15 and the terminal 12 may be disengaged. It was necessary to take measures such as pivoting the left and right end portions of the housing to the housing 14 using metal fittings. As described above, the conventional connector 10 has inconveniences such as complicated manufacturing.

However, as the amount of data handled in recent years has increased, the number of terminals required for one connector has increased, so the width of the connector has increased. For this reason, since the distance from the both ends of the housing 14 is apart near the center in the width direction of the connector, the force for pressing the terminals 12 and 13 against the flat conductor 16 even when the metal fittings are provided. There was a disadvantage of being weak.

  The present invention aims to improve a flat conductor connector and a method for manufacturing the same, and more specifically, in order to eliminate the inconvenience, a flat conductor that can support a pressing member reliably and is easy to manufacture. An object of the present invention is to provide a connector and a method for manufacturing the same.

In order to achieve the above-mentioned object, the flat conductor connector of the present invention is such that an insulating pressing member is pivotally supported around a shaft portion with respect to an insulating housing, and the pressing member is A flat conductor is inserted in an upright state, and is a connector that presses the flat conductor against a plurality of terminals by tilting the pressing member to electrically connect them, and the terminals are plate-shaped, A plurality of contacts fixed in parallel in the plate thickness direction to the housing, extending to the contact surface side of the flat conductor and contacting the contact surface, and an arm portion extending to the back surface side of the flat conductor The arm portion is provided with a bearing portion and a shaft hole for pivotally supporting the shaft portion of the pressing member, and the bearing portion has an arc portion whose outer peripheral surface is formed in an arc shape. The shaft hole is formed in a circular shape, and the pressing member and the housing are provided with the terminal. Molded by insert molding for injecting a molten resin in multiple parallel state into the mold cavity, the pressing member, the injected molten resin toward the shaft hole of said plurality of terminals, and the shaft portion, An operation portion that can be rotated from the outside and a pressing portion that presses the flat conductor toward the contact portion are formed.

  According to the flat conductor connector having the above configuration, since the shaft portion of the pressing member is provided through the shaft hole of the terminal, the pressing member is pivotally supported by all the terminals. Therefore, unlike the conventional connector in which the pressing member is locked to only one of the two types of terminals, the pressing member can be reliably supported on the terminal. Further, since the pressing member is formed by insert molding, it is not necessary to incorporate the pressing member into the terminal or the housing. Therefore, the flat conductor connector of the present invention can be more efficient in manufacturing process than the conventional connector. In addition, since the outer peripheral surface of the bearing portion is formed in an arc shape and the shaft hole is formed in a circular shape, even when the pressing member is formed by insert molding, the pressing member can be easily used in use. Can be rotated with respect to the bearing portion.

  In the flat conductor connector of the present invention, it is preferable that insert molding is performed in a state where the pressing member is raised. According to this, since the pressing member and the terminal are fixed by insert molding in a state in which the pressing member is erected, the state in which the pressing member is erected is maintained until the connector is used. In addition, since the connector can be supplied to the user in a state where the pressing member is erected, the user does not need to erect the pressing member when using the connector.

  In the flat conductor connector of the present invention, it is preferable that the plate thickness of the bearing portion around the shaft hole of the terminal is inclined so as to become thinner in the direction in which the pressing member falls. Since the pressing member is formed by insert molding, the pressing member and the terminal are fixed in an initial state. However, according to the configuration, the user pushes the pressing member in order to use the connector. When it is turned, the fixing surface between the pressing member and the portion around the shaft hole of the terminal is separated, and once the fixing surface is separated, the two members move in the direction away by the inclination, so that no frictional force is generated. Therefore, with this configuration, the sticking between the pressing member and the terminal can be released with a small force.

  Further, in this configuration, the pressing member includes a protruding portion that protrudes on the opposite side to the operation portion across the shaft portion at a position overlapping the bearing portion of the terminal when the shaft portion is viewed from the axial direction. It is preferable that the protruding amount is narrower than the minimum width when the bearing portion is viewed from the axial direction. When the protruding amount of the protruding portion is small, the contact resistance with the bearing portion when the pressing member is rotated becomes small, and the operation of the pressing member becomes smooth.

  In the flat conductor connector of the present invention, it is preferable that the center of the shaft hole is offset toward the contact portion side with respect to the arc center of the arc portion of the bearing portion. According to this configuration, when the pressing member is rotated during use of the connector of the present invention, the fixed portion between the bearing portion and the pressing member is peeled off on the contact portion side due to the offset. When the pressing member is rotated, it can be rotated with a light force.

  Further, in the flat conductor connector of the present invention, the shaft hole is provided with a slit that opens toward the outer edge of the bearing portion, and the slit is closed at the time of insert molding by the mold, and is opened after the insert molding. It is preferable. With this configuration, when the insert molding is completed, a gap is generated between the shaft portion of the pressing member and the shaft hole of the terminal, so that the area of the fixing portion between the bearing portion and the pressing member is reduced. Accordingly, the user can rotate the pressing member with a light force when rotating the pressing member.

  In the flat conductor connector of the present invention, it is preferable that the slit opens from the shaft hole toward the contact portion. According to the said structure, when the said pressing member presses the said flat conductor, since the force produced in the axial part of the said pressing member is applied to the other side of the said slit, the said slit may open or deform | transform. Absent.

  In order to achieve the above object, the flat conductor connecting connector manufacturing method of the present invention is the flat conductor connecting connector manufacturing method according to claim 1, wherein the mold includes the housing. Housing cavity to be molded, housing injection port for injecting molten resin into the housing cavity, pressing member cavity for molding the pressing member, and pressing member to inject molten resin into the pressing member cavity A terminal installation step for installing the terminal in the terminal storage section in a state where the mold is open, and closing the mold for the housing An injection step of injecting a molten resin into the cavity and the cavity for the pressing member, and in the injection step, from the injection port for the pressing member toward the shaft hole of the terminal The molten resin is injected the fusion resin was drained on the operation unit side from the shaft portion side, characterized in that filling.

  In this way, when the molten resin is injected from the pressing member injection port toward the shaft hole of the terminal, the degree of so-called “sinking” in which the resin contracts when the molten resin is cooled and solidified is injected. The radial direction around the axis is larger than the axial direction. Thereby, since the outer diameter of the shaft portion of the pressing member becomes smaller than the inner diameter of the shaft hole of the terminal, the rotation operation of the pressing member becomes smooth.

  Moreover, in the manufacturing method of the flat conductor connection connector of this invention, it is preferable that the said cavity for press members is a shape of the state which the said press member stood with respect to the said housing. By making the pressing member cavity into such a shape, the product after the insert molding is in a state where the pressing member is erected. Therefore, the user does not need to raise the pressing member when using the connector.

  The flat conductor connecting connector manufacturing method of the present invention is the flat conductor connecting connector manufacturing method according to claim 6 or 7, wherein the mold presses the bearing portion when the mold is closed. And a closing member for closing the slit. The slit of the shaft hole is closed during insert molding by the closing member, and the slit is opened by the elasticity of the bearing portion after the mold is opened. Therefore, after the insert molding, the fixing portion of the shaft portion of the pressing member and the shaft hole of the bearing portion is peeled off, so that the contact area between the pressing member and the bearing portion is reduced and the frictional resistance is reduced. The operation of the pressing member is facilitated.

In FIG. 4B, a state where the pressing member 5 is tilted in the direction of pressing the FPC 6 is indicated by a one-dot chain line.

  Next, the manufacturing method of the connector of this embodiment is demonstrated. The connector manufacturing method of the present embodiment includes a terminal formation process, a terminal installation process, and an injection process, and various processes are performed using the mold 7.

  As shown in FIG. 5, the mold 7 used in the manufacturing method of the present embodiment includes an upper mold 71, a lower mold 72, a slide core 73, and an angular pin 74, where the upper mold 71 is a movable mold and a lower mold 71. The mold 72 is a fixed mold. A cavity 75 having a shape corresponding to the connector 1 is formed by the upper mold 71, the lower mold 72, and the slide core 73. As shown in FIG. 5B, the cavity 75 includes a pressing member cavity 75 a cut into the shape of the pressing member 5 and a housing cavity 75 b cut into the shape of the housing 4. . Further, in the cavity 75 of the lower mold 72, a terminal accommodating portion 76 to which the first terminal 2 and the second terminal 3 are alternately mounted is provided.

  In FIG. 5, the boundary line between the upper mold 71 and the lower mold 72 is a parting line PL. The angular pin 74 is fixed to the upper die 71 by a plate 71 a so as to move up and down integrally with the upper die 71. The plate 71a is provided with a trapezoidal pressing block 71b. When the mold 7 is closed, the pressing block 71b presses the inclined surface of the left end portion of the slide core 73 in FIG. 5A to slide the slide core 73 to the right side in the drawing.

  As shown in FIG. 5 (b), the upper die 71 has a pressing member injection port 77 for injecting a molten resin to be the pressing member 5, a pressing member runner 78 to which the molten resin is supplied, and the housing 4. A housing injection port 79 for injecting molten resin, a housing runner 80, a pressing member runner 78, and a sprue 81 for supplying resin to the housing runner 80 are provided. The pressing member injection port 77 is provided at a position where the molten resin is injected toward the shaft holes 24 and 34 of the first terminal 2 and the second terminal 3. The housing injection port 79 is provided at a position for injecting molten resin toward the fixing holes 25 and 35 of the first terminal 2 and the second terminal 3. Further, in the mold 7 according to the present embodiment, as shown in FIGS. 5A and 5B, the pressing member cavity 75 a and the housing are arranged so that the pressing member 5 stands up with respect to the housing 4. A cavity 75b is formed.

  Also, as shown in FIG. 6, in this embodiment, a pair of cavities 75 are formed on the left and right so that two connectors 1 can be formed with a single mold 7. As shown in FIG. 6, the molten resin supplied into the sprue 81 passes through the pressing member runner 78 and the housing runner 80, and is pressed from the left and right pressing member injection ports 77 and the housing injection port 79. It is injected into the cavity 75a and the housing cavity 75b.

  In the manufacturing method of the present embodiment, first, in the terminal forming step, the metal plate is pressed by a known punch press (not shown) to form the first terminal 2 and the second terminal 3. At this time, pressing is performed so that no burrs are left in the bearing portions 23 and 33 and the shaft holes 24 and 34. The first terminal 2 and the second terminal 3 formed in this way are aligned in a direction by a known aligner (not shown), and the first terminal 2 and the second terminal 3 are arranged alternately. It is conveyed to the mold 7 where the next terminal installation process is performed.

  In the terminal installation process, as shown in FIG. 7A, the first terminal 2 and the second terminal formed in the terminal formation process in a state where the upper mold 71 and the lower mold 72 of the mold 7 are opened. 3 is set in a terminal accommodating portion 76 provided in the cavity 75 of the mold 7 by using a transfer machine (not shown).

  Next, as shown in FIG. 7B, the upper mold 71 is moved closer to the lower mold 72 to perform mold closing. When the upper mold 71 is lowered, the slide core 73 is moved rightward in FIG. When the upper mold 71 and the lower mold 72 are closed, the slide core 73 is slid by the pressing block 71b, and the comb-shaped portion at the tip of the slide core 73 is inserted between the terminals. A cavity 75 is formed by 72 and the slide core 73.

  In the injection step, molten resin is injected into the housing cavity 75b and the pressing member cavity 75a. At this time, the molten resin injected into the pressing member cavity 75 a passes through the sprue 81 and the pressing member runner 78 from the pressing member injection port 77 to the shaft holes 24 of the first terminal 2 and the second terminal 3. It is injected toward 34. Thus, in the pressing member cavity 75a, first, the resin is filled in the portion of the shaft portion 52 of the pressing member 5, and after the molten resin is filled in the shaft portion 52, the pressing portion 53, the protruding portion 54, and the operation portion. The resin flows toward the inside 51, and the pressing member cavity 75a is filled with the resin.

  The molten resin injected into the housing cavity 75 b is injected from the housing injection port 79 toward the fixing holes 25 and 35 of the first terminal 2 and the second terminal 3 via the sprue 81 and the push housing runner 80. Is done. Thereby, in the housing cavity 75b, the molten resin is filled in the fixing holes 25 and 35, and then the resin flows toward other portions, and the resin is filled in the housing cavity 75b.

  In this way, after each cavity is filled with the molten resin, the process waits until the molten resin solidifies and the mold can be opened, and then the mold 7 is opened to remove the connector 1 from the mold 7. . The connector 1 of this embodiment is manufactured by the above process.

  The connector 1 manufactured by the above process is supplied to a user such as an electrical equipment manufacturer with the pressing member 5 standing. For example, the user mounts the connector 1 on a printed wiring board (not shown). When connecting the connector 1 and the FPC 6, the connecting portion 26 of the FPC 6 is inserted from the front of the connector 1, and the arm portions 22 and 32 of the first terminal 2 and the second terminal 3 and the contact portions 21 and 31 are connected. Insert between. Thereafter, the operator tilts the pressing member 5 toward the FPC 6 to connect the FPC 6 and the connector 1. Thus, since the user does not need to raise the pressing member 5 as in the prior art when connecting the connector 1 and the FPC 6, the connection work can be easily performed.

  At that time, as shown in FIG. 4A, the bearing portions 23 and 33 of the first terminal 2 and the second terminal 3 are configured such that the plate thickness on the FPC 6 side gradually decreases from the top to the bottom. Therefore, when the pressing member 5 is rotated to the FPC 6 side, the close contact portions around the shaft portions 52 of the bearing portions 23 and 33 and the pressing member 5 are peeled off, and thereafter the pressing member 5 is smoothly rotated. become able to. Further, since the center C of the arc portions 23a and 33a of the bearing portions 23 and 33 and the center C ′ of the shaft holes 24 and 34 are offset, if the pressing member 5 is rotated, the lower left of the bearing portions 23 and 33 In the direction (offset direction), the fixing portion between the outer peripheral surface of the shaft portion 52 of the pressing member 5 and the inner peripheral surfaces of the shaft holes 24 and 34 is peeled off, so that the rotation operation of the pressing member 5 is lightened.

  In the above embodiment, the first terminal 2 and the second terminal 3 are shaped as shown in FIG. 2, but the bearing portion 23 and the shaft hole 24 that support the shaft portion 52 of the pressing member 5 are provided. If so, the shape of the other part can be appropriately changed according to the user's request. Further, in the manufacture of the connector 1, the pressing member 5 is inserted and molded at a substantially right angle with respect to the housing 4 of the connector 1. However, the invention is not limited thereto, and the pressing member 5 is raised when the user connects the FPC 6 or the like. The angle may be slightly different as long as labor is saved. Further, although the center C ′ of the shaft holes 24 and 34 is offset in the lower left direction with respect to the center C of the arc portions 23a and 33a, it is not limited to this and is offset only to the left in FIG. Alternatively, it may be offset only downward.

  Next, a connector 1A according to a second embodiment of the present invention will be described with reference to FIG. The connector 1A of the second embodiment opens downward in the shaft holes 24 and 34 provided in the bearing portions 23 and 33 of the first terminal 2 and the second terminal 3 as shown in FIG. Slits 27 and 37 are provided. The slits 27 and 37 are formed so as to expand downward. FIG. 8B shows a state in which the terminals 2 and 3 are accommodated in the mold 7. The mold 7 is provided with a closing member 73a that presses the bearing portions 23 and 33 to close the slits 27 and 37 when the mold is closed. The closing member 73a is fixed to the slide core so as to operate integrally with the slide core 73 (see FIG. 7). Since other configurations are the same as those in the above embodiment, detailed description thereof is omitted.

  The connector 1A of the second embodiment is manufactured as follows. First, in the terminal installation step, the first terminal 2 and the second terminal 3 are installed in the terminal storage portion 76 in the mold 7. At this time, the bearing portions 23 and 33 of both terminals are in a state in which the slits 27 and 37 are opened as shown in FIG. When the mold 7 is closed from this state, as shown in FIG. 8B, the closing member 73a integrated with the slide core 73 approaches the terminal bearings 23 and 33, and the mold is closed. When this is completed, the bearings 23 and 33 are pressed by the closing member 73a as shown in FIG. 8C, and the slits 27 and 37 are closed.

  Next, molten resin is injected into the cavity 75 in the injection process. At this time, as shown in FIG. 8C, since the slits 27 and 37 are closed in the shaft holes 24 and 34, the molten resin does not leak from the slits 27 and 37 to the outside.

  Next, when the mold 7 is opened after the molten resin is solidified, the closing member 73a is separated from the bearing portions 23 and 33 as shown in FIG. Then, since the bearing portions 23 and 33 return to the original state due to the elasticity of the bearing portions 23 and 33 themselves, the diameters of the shaft holes 24 and 34 are wider than when the mold is closed. Thereby, the surface of the internal peripheral surface of the bearing parts 23 and 33 and the surface of the axial part 52 of the press member 5 peels, and a clearance gap arises.

  Since the connector 1A of the second embodiment has the above configuration, when the user rotates the pressing member 5 when using the connector 1A, the inner peripheral surfaces of the bearing portions 23 and 33 are already Since a part with the outer peripheral surface of the axial part 52 has peeled, the press member 5 can be rotated with a light force.

  In the second embodiment, the slits 27 and 37 are provided below the shaft holes 24 and 34. However, the slits 27 and 37 may be provided above or in front.

  Next, a connector 1B according to a third embodiment of the present invention will be described with reference to FIG. As shown in FIG. 9A, the bearing portions 23 and 33 of the connector 1B according to the third embodiment are such that the shaft holes 24 and 34 are largely offset downward from the centers of the arc portions 23a and 33a of the bearing portions 23 and 33. The slits 28 and 38 are provided largely downward. Further, a trapezoidal protrusion 73 b is provided on the upper surface of the slide core 73 of the mold 7 in accordance with the shape of the slits 28 and 38. Since other configurations are the same as those in the above embodiment, detailed description thereof is omitted.

  The manufacturing process of the connector 1B of the third embodiment is as follows. First, in the terminal installation step, the first terminal 2 and the second terminal 3 are installed in the terminal storage portion 76 in the mold 7. At this time, the bearing portions 23 and 33 of both terminals are in a state where the slits 28 and 38 are opened as shown in FIG. When the mold 7 is closed from this state, the slide core 73 approaches the terminal bearings 23 and 33 as shown in FIG. 9B, and the slide core 73 is moved to the right side in FIG. 9B. When the slide core 73 moves, the projections 73b are fitted into the slits 28 and 38, and the shaft holes are moved. 24 and 34 are closed.

  Next, when the mold 7 is opened after the molten resin is solidified, the lower end portions 23f and 33f of the bearing portions 23 and 33 are moved in the opening direction by the protrusions 73b as shown in FIG. 9 (d). The surfaces of the inner peripheral surfaces of the bearing portions 23 and 33 and the shaft portion 52 are peeled off. Thereafter, when the slide core 73 is further moved, the lower end portions 23f and 33f of the bearing portions 23 and 33 are disengaged from the projections 73b, and the lower end portions 23f and 33f are returned to their original positions by the elasticity of the bearing portions 23 and 33 themselves. Return to.

  Since the connector 1B of the third embodiment has the above-described configuration, when the user rotates the pressing member 5 when using the connector 1B, the inner peripheral surfaces of the bearing portions 23 and 33 are already Since a part with the outer peripheral surface of the axial part 52 has peeled, the press member 5 can be rotated with a light force.
