Description

Connector for flat conductor and method of manufacturing the same Field of invention

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

Background of the invention

According to the prior art, the connector 10 in the patent document 1 (Japanese Patent Laid-Open Publication No. 2008-27593) or Non-Patent Document 1 (http://www.hirose.co.jp/catalogj_hp/j58302093.pdf) is known. The connector 10 is used for connecting a flat conductor 16 of an FPC, a flat cable or the like to a circuit board. As shown in Figs. 10(a) and (b), the conventional connector 10 has two kinds of terminals 12 and 13 having different shapes in the width direction in the housing 14 made of an insulating synthetic resin. They are alternately arranged and have a plate-shaped pressing member 15 which is rotatably engaged with the casing 14 and the terminals 12, 13. At the same time, the terminals 12 and 13 respectively have receiving spaces 12a and 13a for receiving the flat conductor 16. When the flat conductor 16 is inserted into the receiving spaces 12a and 13a, the front and back surfaces of the flat conductor 16 face a part of the terminal and are flat. The type conductor 16 and the connector 10 are brought into contact by the contact portions of the flat conductors 16 via the contact portions 12b, 13b.

As disclosed in FIG. 10 (see Non-Patent Document 1), the conventional connector 10 is provided with an inverted U-shaped shaft support portion 12c on one of the terminals 12 to engage the rotation axis of the pressing member 15. 15a, the pressing member 15 is supported only by the terminal 12 or by a shaft supporting portion (not shown) provided in the casing 14 because the other terminal 13 is not provided with the shaft supporting portion. Shaft support.

However, in recent years, the terminals 12, 13 have become quite thin in order to meet the demand for miniaturization of the connector. Therefore, when the pressing member 15 is supported by only one of the terminals 12 or the housing 14 is pivotally supported, the force for pushing the terminal to the flat conductor 16 is weak, which may cause contact failure.

Further, the conventional connector 10 is formed by assembling the individually formed pressing members 15 after assembling the terminals 12 and 13 into the casing 14. Here, since the shaft support portion 12c of the terminal 12 is of an inverted U shape, when a strong force is applied downward to the pressing member 15, the engagement between the pressing member 15 and the terminal 12 may be detached, and it is necessary to use it. The metal parts and the like are supported by the left and right end portions of the pressing member 15 being axially supported by the casing 14. As described above, the conventional connector 10 also has problems such as cumbersome manufacturing.

However, since the number of data processing increases in recent years, a connector often requires more terminals, and thus the width of the connector is widened. Therefore, since the vicinity of the center position in the width direction of the connector is far from both end portions of the casing 14, even when the metal parts or the like are provided, there is a force for pushing the terminals 12, 13 toward the flat conductor 16. Weaker problem.

An object of the present invention is to improve a flat connector and a method of manufacturing the same, and more particularly to provide a connector for a flat conductor that can reliably support a pressing member and that can be easily manufactured, and a manufacturing method thereof. .

In order to achieve the above object, the connector for a flat conductor of the present invention is a connector in which the pressing member of the insulating system is rotatably supported around the shaft portion with respect to the housing of the insulating system. Inserting a flat conductor in an upright state of the pressing member, pushing the flat member to push the plurality of terminals by pushing down the pressing member, electrically connecting the flat conductor and the plurality of terminals, the connector for the flat conductor The terminal is formed in a plate shape, and is arranged and fixed on the casing in a plurality of plate thickness directions, and the terminal has a contact surface side of the flat conductor extending in contact with the contact surface. a contact portion and a wrist portion extending toward a reverse side of the flat conductor, wherein the wrist portion is provided with a bearing portion and a shaft that rotatably supports a shaft portion of the pressing member a hole having a circular arc portion in which an outer peripheral surface is formed in an arc shape, the shaft hole being formed in a circular shape; and the pressing member and the housing are arranged in a plurality of the terminals by arranging the terminal Injection in the state of the cavity Forming by insert molding of a molten resin; injecting molten resin into a shaft hole of the plurality of terminals, the shaft portion, an operation portion capable of rotating from the outside, and pushing the flat conductor toward the The pressing portion on the side of the contact portion is molded.

According to the connector for a flat conductor 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 supported by all the terminal shafts. So, like the existing connector, push The connector is only engaged with the connector on one of the two types of terminals, and the pressing member can be reliably pivotally supported on the terminal. In addition, since the pressing member is molded by insert molding, it is not necessary to assemble the pressing member to the terminal or the housing. Therefore, the manufacturing process of the connector for a flat conductor of the present invention is also more efficient than that of the conventional connector. Further, since the outer peripheral surface of the bearing portion is formed in an arc shape, the shaft hole is formed in a circular shape, and therefore, even when the pressing member is molded by insert molding, it can be used at the time of use. The pressing member is simply rotated relative to the bearing portion.

Further, in the connector for a flat conductor of the present invention, it is preferable that the insert member is formed in a state in which the pressing member is erected. According to this, since the pressing member and the terminal are held by insert molding in a state where the pressing member is erected, the pressing member is always held until the connector is used. The state of erection. At the same time, since the connector can be provided to the user in a state where the pressing member is erected, it is not necessary for the user to erect the pressing member in using the connector.

Further, in the connector for a flat conductor of the present invention, it is preferable that the thickness of the bearing portion around the shaft hole of the terminal is inclined so as to be thinner in a direction in which the pressing member is pushed down. Since the pressing member is molded by insert molding, the pressing member and the terminal are held in an initial state, but according to the configuration, the user pushes the pressing member in order to use the connector. When rotating in the push-down direction, the pressing member is separated from the holding surface of the portion around the shaft hole of the terminal, and once the holding surface is separated, since the two members move in the separating direction due to the tilting, friction does not occur. force. Therefore, according to this configuration, the holding member and the terminal can be held by a small force.

Further, in the configuration, when the shaft portion of the pressing member is viewed from the axial direction, it is preferable that a portion of the protruding portion that protrudes in the opposite direction of the operating portion via the shaft portion is overlapped between the terminal and the bearing portion. The amount of protrusion is smaller than the minimum width of the shaft portion when the bearing portion is viewed from the shaft portion. When the amount of protrusion of the protruding portion is small, the contact resistance between the pressing member and the bearing portion when the pressing member is rotated is reduced, and the operation of the pressing member can be smoothly performed.

Further, in the connector for a flat conductor of the present invention, it is preferable that a center of the shaft hole is offset from a center of a circular arc of the arc portion of the bearing portion toward the contact portion side. According to this configuration, when the connector of the present invention is used, once the pressing member is rotated, the user is detached from the holding portion of the pressing member on the side of the contact portion, and thus the user When the pressing member is rotated, it is only necessary to use a light force to cause it to rotate.

Further, in the connector for a flat conductor of the present invention, it is preferable that a slit that opens to an outer edge of the bearing portion is provided in the shaft hole, the slit being insert-molded by the mold Closed and opened after insert molding. According to this configuration, after the insert molding is completed, the area of the holding portion of the bearing portion and the pressing member is reduced due to the occurrence of a gap between the shaft portion of the pressing member and the shaft hole of the terminal. Therefore, when the user rotates the pressing member, it is only necessary to use a light force to cause it to rotate.

Further, in the connector for a flat conductor of the present invention, it is preferable that the slit is opened from the shaft hole toward the contact portion side. According to this configuration, when the pressing member pushes the flat conductor, since the force generated on the shaft portion of the pressing member is applied to the reverse side of the slit, the slit Will not open or deform.

Further, in order to achieve the above object, a method of manufacturing a connector for a flat conductor connection according to the present invention is the method of manufacturing the connector for a flat conductor connection according to claim 1, wherein the mold has a housing. a cavity for molding the casing; an injection port for the casing, and a molten resin injected into the cavity of the casing; a cavity for pressing the member to form the pressing member; and an injection port for the pressing member a molten resin is injected into the cavity for the pressing member, and the terminal accommodating portion houses the terminal. The manufacturing method includes a terminal setting step, and the terminal is placed in a state where the cavity is opened. In the terminal accommodating portion; in the injection step, the mold is closed, and the molten resin is injected into the cavity for the casing and the cavity for the pressing member, and the pressing member is used for the pressing member. The injection port injects molten resin into the shaft hole of the terminal, and the molten resin flows from the shaft portion side to the operation portion side to be filled.

When the molten resin is injected into the shaft hole of the terminal from the injection port for the pressing member, the molten resin is cooled and solidified, and the diameter of the shaft is smaller than the diameter of the resin in the axial direction of the injection. Bigger. Therefore, since the outer diameter of the shaft portion of the pressing member is smaller than the inner diameter of the shaft hole of the terminal, the rotating operation of the pressing member can be smoothly performed.

Further, in the method of manufacturing the connector for a flat conductor of the present invention, it is preferable that a shape of the cavity for the pressing member coincides with a state in which the pressing member is erected with respect to the casing. By making the pressing member cavity into such a shape, the pressing member of the insert molded product is in an upright state. Therefore, when the user uses the connector, it is not necessary to erect the pressing member.

Further, a method of manufacturing a connector for a flat conductor connection according to the present invention is the method of manufacturing the connector for a flat conductor connection according to the sixth aspect of the invention or the seventh aspect of the invention. The mold has a closing member that presses the bearing portion when the mold is closed to close the slit. At the time of insert molding, the slit of the shaft hole is closed by the closing member, and the slit is opened by the elasticity of the bearing portion after the mold is opened. Therefore, since the shaft portion of the pressing member and the retaining portion of the shaft hole of the bearing portion are disengaged after the insert molding, the contact area of the pressing member and the bearing portion is reduced to reduce the frictional resistance. Therefore, the operation of the pressing member becomes easy.

Further, in Fig. 4(b), the state in which the pressing member 5 is pushed down in the direction in which the FPC 6 is pushed is indicated by a one-point lock line.

Next, a method of manufacturing the connector of the present embodiment will be described. The method of manufacturing the connector of the present embodiment includes a terminal forming step, a terminal setting step, and an injection molding step, and various steps are performed using the mold 7.

As shown in Fig. 5, the mold 7 used in the manufacturing method of the present embodiment has an upper mold 71, a lower mold 72, a sliding core 73, and a skew guide column 74. The upper mold 71 is movable, and the lower mold 72 is of a fixed type. 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. 5(b), the cavity 75 has a cavity 75a for pressing the member corresponding to the shape of the pressing member 5, and a cavity for cutting the casing corresponding to the shape of the casing 4. 75b. Further, in the cavity 75 of the lower mold 72, a terminal accommodating portion 76 in which the first terminal 2 and the second terminal 3 are alternately placed is provided.

In Fig. 5, the parting line PL is a boundary line between the upper mold 71 and the lower mold 72. Further, the inclined guide post 74 is fixed to the upper mold 71 by the plate member 71a so that the inclined guide post 74 and the upper mold 71 move up and down in an integrated manner. Further, a trapezoidal pressing block 71b is provided on the plate member 71a. When the mold 7 is closed, the pressing block 71b pushes the inclined surface of the left end portion of the sliding core 73 in the fifth drawing, and slides the sliding core 73 to the right side in the drawing.

As shown in Fig. 5(b), the upper mold 71 is provided with an injection port 77 for pressing members, and is injected with molten resin to be the pressing member 5; the pressing member is provided with a flow path 78 for supplying molten resin; The injection port 79 is injected into the molten resin of the casing 4; the flow path 80 for the casing; the flow path 78 for the pressing member; and the gate 81 for supplying the resin to the flow path 80 for the casing. The pressing member injection port 77 is provided at a position where the molten resin can be injected into the shaft holes 24, 34 of the first terminal 2 and the second terminal 3. At the same time, the housing injection port 79 is provided at a position where the molten resin can be injected to the fixing holes 25, 35 of the first terminal 2 and the second terminal 3. Further, as shown in Fig. 5 (a) and (b), in the mold 7 of the present embodiment, the pressing member 5 is formed in an upright state with respect to the casing 4, and the pressing member cavity 75a is formed. The mold cavity 75b for the housing.

Further, as shown in Fig. 6, in the present embodiment, in order to mold the two connectors 1 in one mold 7, the cavity 75 is formed in a pair of right and left. As shown in Fig. 6, the molten resin supplied into the gate 81 passes through the pressing member flow path 78 and the casing flow path 80, and is injected from the left and right pressing member injection ports 77 and the casing injection port 79. It is injected into the cavity 75a for the pressing member and the cavity 75b for the casing.

In the manufacturing method of the present embodiment, first, in the terminal forming step, the metal is pressed by a known punch (not shown) to mold the first terminal 2 and the second terminal 3. At this time, the bearing portions 23 and 33 and the shaft holes 24 and 34 are subjected to press working without leaving burrs. The first terminal 2 and the second terminal 3 formed in this manner are aligned by a known alignment machine (not shown), and the first terminal 2 and the second terminal 3 are alternately arranged, and then transferred to the mold 7 for carry out. The next terminal setting process.

As shown in Fig. 7 (a), in the terminal setting step, in the state where the upper mold 71 and the lower mold 72 of the mold 7 are opened, the transfer molding apparatus (not shown) molds the terminal molding process. The first terminal 2 and the second terminal 3 are placed in the terminal housing portion 76 provided in the cavity 75 of the mold 7.

Next, as shown in Fig. 7(b), the upper mold 71 is brought close to the lower mold 72, and the mold is closed. Once the upper mold 71 is lowered, the slide core 73 is moved to the right direction in Fig. 7(b) by the inclined guide post 74. Further, once the upper mold 71 and the lower mold 72 are closed, the slide core 73 is moved by the pressing block 71b, and the comb portion at the tip end of the slide core 73 is inserted into the middle of each of the terminals, passing through the upper mold 71, the lower mold 72, and The sliding core 73 forms a cavity 75.

In the injection step, the molten resin is injected into the cavity 75b for the casing and the cavity 75a for the pressing member. At this time, the molten resin injected into the cavity 75a for pressing the member is injected into the first terminal 2 and the second terminal 3 from the injection port 77 for the pressing member via the gate 81 and the flow path 78 for the pressing member. Shaft holes 24, 34. Thus, in the pressing member cavity 75a, first, the portion of the shaft portion 52 of the pressing member 5 is filled with resin, and after the shaft portion 52 is filled with the molten resin, the resin is pressed toward the pressing portion 53, the protruding portion 54, and the operating portion. 51 flows, and the inside of the cavity 75a for pressing members is filled with resin.

The molten resin injected into the cavity 75b for the casing is injected from the injection port 79 for the casing to the fixing holes 25, 35 of the first terminal 2 and the second terminal 3 through the gate 81 and the flow path 80 for the casing. . Thereby, in the cavity 75b for the casing, after the fixing holes 25 and 35 are filled with the molten resin, the resin flows toward the other portion, and the inside of the cavity 75b for the casing is filled with the resin.

Thus, after the cavity is filled with the molten resin, the molten resin is solidified and the mold can be opened, and then the mold is opened, and the connector 1 is taken out from the mold 7. The connector 1 of the present embodiment was manufactured through the above steps.

The connector 1 manufactured by the above process is supplied to a user such as an electric appliance manufacturer in a state where the pressing member 5 is erected. The user mounts the connector 1 to a printed wiring board (not shown), for example. Further, when the connector 1 is connected to the FPC 6, the connection portion 26 of the first terminal 2 is inserted from the front of the connector 1 and inserted into the wrist portions 22, 32 and the contact portion of the first terminal 2 and the second terminal 3. Between 21, 31. Then, the operator pushes the pressing member 5 to the FPC 6 side to connect the FPC 6 to the connector 1. Thus, when the connector 1 and the FPC 6 are connected, since it is not necessary for the user to erect the pressing member 5 as before, the connection operation can be easily performed.

At that time, as shown in FIG. 4( a ), the thickness of the bearing portions 23 and 33 of the first terminal 2 and the second terminal 3 on the FPC 6 side is gradually thinned from the upper top toward the lower side, and the pressing member is pressed. When the FPC 6 is rotated to the FPC 6, the bearing portions 23 and 33 are separated from the contact portion around the shaft portion 52 of the pressing member 5, and thereafter the pressing member 5 can be smoothly rotated. Further, since the center C of the circular arc portions 23a, 33a of the bearing portions 23, 33 and the center C' of the shaft holes 24, 34 are biased, once the pressing member 5 is rotated, at the lower left of the bearing portions 23, 33 (Offset direction), since the contact portion between the outer peripheral surface of the pressing member 5 and the inner peripheral surface of the shaft holes 24, 34 is detached, the turning operation of the pressing member 5 becomes easy.

Further, in the above-described embodiment, the first terminal 2 and the second terminal 3 are designed to have the shape shown in Fig. 2, but the bearing portion for axially supporting the shaft portion 52 of the pressing member 5 is provided. 23 and the shaft hole 24, the shape of other parts can be appropriately changed according to the needs of the user. Further, in the process of manufacturing the connector 1, although the pressing member 5 is erected at substantially right angles to the connector 1, the pressing member 5 is insert-molded, but it is not limited to this form as long as the user is When the connector 1 is connected to the FPC 6 or the like, the trouble of erecting the pressing member 5 can be eliminated, and there is no problem even if the angle is slightly different. Further, although the center C' of the shaft holes 24, 34 is offset to the lower left side with respect to the center C of the circular arc portions 23a, 33a, the present invention is not limited to this form, and may be directed only to FIG. 4(b). It can also be offset on the left side or only downward.

Next, a connector 1A according to a second embodiment of the present invention will be described with reference to Fig. 8. As shown in Fig. 8(a), the connector 1A of the second embodiment is provided with the shaft holes 24, 34 provided at the bearing portions 23, 33 of the first terminal 2 and the second terminal 3, which are opened downward. Cuts 27, 37. The slits 27, 37 are formed to expand downward. Fig. 8(b) shows a state in which the terminals 2, 3 are housed in the mold 7. The mold 7 is provided with a closing member 73a that presses the bearing portions 23, 33 to close the slits 27, 37 when the mold is closed. The closing member 73a is fixed to the sliding core 73 in such a manner as to integrally move with the sliding core 73 (see Fig. 7). In addition, since the other structure is the same as that of the above-mentioned embodiment, detailed description is abbreviate|omitted.

The connector 1A of the second embodiment is manufactured in the following manner. First, in the terminal setting step, the first terminal 2 and the second terminal 3 are placed in the terminal housing portion 76 inside the mold 7. At this time, as shown in Fig. 8(a), the slits 27, 37 of the bearing portions 23, 33 of the two terminals are in an open state. When the mold 7 is closed in this state, as shown in Fig. 8(b), the closing member 73a and the sliding core 73 are integrally joined to the bearing portions 23 and 33 of the terminal, as shown in Fig. 8(c). When the mold closing is completed, the bearing portions 23 and 33 are pressed by the closing member 73a, and the slits 27 and 37 are closed.

Next, in the injection step, molten resin is injected into the cavity 75. At this time, as shown in Fig. 8(c), since the slits 27, 37 of the shaft holes 24, 34 are closed, the molten resin does not leak from the slits 27, 37 to the outside.

Subsequently, after the molten resin is solidified, once the mold 7 is opened, as shown in Fig. 8(d), the closing member 73a is detached from the bearing portions 23, 33. Then, the bearing portions 23 and 33 return to the original state by their own elasticity, and the diameters of the shaft holes 24 and 34 are larger than those at the time of mold closing. Thereby, the inner peripheral surfaces of the bearing portions 23 and 33 are separated from the surface of the shaft portion 52 of the pressing member 5 to form a slit.

Since the connector 1A of the second embodiment has the above configuration, when the pressing member 6 is rotated when the user uses the connector 1A, since the inner circumferential surface of the bearing portions 23, 33 has been separated from the outer peripheral surface of the shaft portion 52, only It is necessary to apply a very light force to rotate the pressing member 5.

Further, in the second embodiment described above, although the slits 27, 37 are opened below the shaft holes 24, 34, they may be opened above or in front.

Next, a connector 1B according to a third embodiment of the present invention will be described with reference to Fig. 9. As shown in Fig. 9(a), the shaft holes 24, 34 of the bearing portions 23, 33 of the connector 1B of the third embodiment are largely offset downward from the center of the arc portions 23a, 33a of the bearing portions 23, 33. Set and set the large slits 28, 38 downward. Further, a trapezoidal projection 73b is provided on the upper surface of the sliding core 73 of the mold 7, and the shape of the trapezoidal projection 73b corresponds to the shape of the slits 28 and 38. In addition, since the other structure is the same as that of the above-mentioned embodiment, detailed description is abbreviate|omitted.

The manufacturing process of the connector 1B of the third embodiment is as follows. First, in the terminal setting step, the first terminal 2 and the second terminal 3 are placed in the terminal housing portion 76 inside the mold 7. At this time, as shown in Fig. 9(a), the slits 28, 38 of the bearing portions 23, 33 of the two terminals are in an open state. When the mold 7 is closed in this state, as shown in Fig. 9(b), the sliding core 73 approaches the bearing portions 23, 33 of the terminal, and when the sliding core 73 is further turned into Fig. 9(b) When the right side moves, the lower end portions 23f and 33f in front of the bearing portions 23 and 33 rest on the projections 73b and are lifted upward, and when the sliding core 73 continues to move, the projections 73b are engaged in the slits 28 and 38. The shaft holes 24, 34 are closed.

Then, after the molten resin is solidified, once the mold 7 is opened, as shown in Fig. 9(d), the lower end portions 23f and 33f of the bearing portions 23 and 33 are moved in the direction in which the slits 28 and 38 are opened by the projections 73b, and the bearing portion is moved. The inner circumferential surface of 23, 33 is separated from the surface of the shaft portion 52.
