Description

Connector for parallel conductor and method for manufacturing same

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting a balanced conductor such as an FPC (flexible substrate) or a flat cable to a circuit board or the like and a manufacturing method thereof.

Conventionally, as shown in the following patent document 1 and the following nonpatent document 1, the connector 10 which connects balanced conductors 16, such as an FPC and a flat cable, to a circuit board etc. is known. As shown in Figs. 10A and 10B, the conventional connector 10 alternately arranges two kinds of terminals 12 and 13 having different shapes in the width direction in the housing 14 made of an insulating synthetic resin. And a plate-like pressing member 15 which is rotatably coupled to the housing 14 and the terminals 12 and 13. In addition, the terminals 12 and 13 have import spaces 12a and 13a for receiving the balanced conductors 16, respectively, and when the balanced conductors 16 are inserted into the import spaces 12a and 13a, respectively. A part of a terminal faces the front and back, and the contact part 12b, 13b is made to contact the contact part of the balanced conductor 16, and the balanced conductor 16 and the connector 10 are connected.

The conventional connector 10 has an inverted U-shape so as to be engaged with the rotation shaft 15a of the pressing member 15 to one terminal 12, as disclosed in FIG. 10 (see Non-Patent Document 1). 12c is provided, and since the other terminal 13 is not provided with the same structure as the bearing part, the press member 15 is supported only by the terminal 12, or the housing ( It is to be further supported by a paper sheet (not shown) provided in 14).

However, in recent years, in order to respond to the request for downsizing of the connector, the terminals 12 and 13 have become very thin. For this reason, when the pressing member 15 is supported only by one terminal 12 and when it is supported by the housing 14, the force which presses a terminal against the balance conductor 16 weakens, and may cause a bad contact. Occurs.

In addition, the conventional connector 10 is formed by inserting the press members 15 separately formed after the terminals 12 and 13 are inserted into the housing 14. Here, the bearing portion 12c of the terminal 12 has an inverted U-shape, and if the downward force is applied to the pressing member 15, the engagement between the pressing member 15 and the terminal 12 may be lost. Therefore, it was necessary to take countermeasures such as holding the left and right ends of the pressing member 15 with the bracket 14 and the like on the housing 14. Thus, the conventional connector 10 had inconveniences such as being complicated in terms of manufacturing.

However, with the recent increase in the amount of handling data, the number of terminals required by one connector is increasing, and thus the width of the connector is widening. For this reason, since the distance from the both ends of the housing 14 is in the vicinity of the center of the width direction of a connector, even if it is equipped with the said bracket etc., the force which presses the terminals 12 and 13 to the balanced conductor 16 is carried out. There was an inadequacy of this weakness.

The present invention aims at improving the balanced conductor connector and the manufacturing method thereof, and more particularly, in order to eliminate the non-compliance, it is possible to reliably axially press the pressing member and to facilitate the manufacture. An object of the present invention is to provide a connector for a flat conductor and a method of manufacturing the same.

In order to achieve the above object, in the connector for balanced conductor of the present invention, the pressing member of the insulating member is rotatably pivoted about the shaft portion with respect to the housing of the insulating member, and the pressing member is standing up. A connector in which a balanced conductor is inserted, and the balanced conductor is pressed down on a plurality of terminals to electrically connect the two to each of the terminals, wherein the terminals are plate-like, and the terminals are plate-like in parallel in a plate thickness direction. A bearing part which is fixed, is provided on the contact surface side of the flat conductor and is in contact with the contact surface, and a arm portion is extended on the back surface side of the balanced conductor, and the arm portion has a bearing part for rotatably bearing the shaft portion of the pressing member; A shaft hole is provided, wherein the bearing portion has an arc portion having an outer circumferential surface having an arc shape, and the shaft hole has a circular shape. And the press member and the housing are formed by insert (insert) molding for injecting molten resin in a state where a plurality of the terminals are arranged in a cavity of the mold, and the press member is formed by axial holes of the plurality of terminals. It is characterized in that the molten resin injected toward the molded body is formed by forming the shaft portion, an operation portion capable of rotating operation from the outside, and a pressing portion for pressing the balanced conductor to the contact portion side.

According to the balanced conductor connector, since the shaft portion of the pressing member penetrates through the shaft hole of the terminal, the pressing member is held by all terminals. Therefore, unlike the conventional connector, the pressing member is reliably held on the terminal, unlike the pressing member being held in only one type of the two types of terminals. In addition, since the press member is molded by insert molding, it is not necessary to insert the press member into the terminal or the housing. Therefore, the manufacturing method of the flat conductor connector of this invention can also be made more efficient compared with the conventional connector. In addition, since the outer circumferential 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 molded by insert (insert) molding, the pressing member can be easily stored in use. It is possible to rotate about wealth.

Moreover, in the connector for balanced conductors of this invention, it is preferable that insertion (insert) molding is performed in the state which the said pressing member stood up. According to this, since the pressing member and the terminal are fixed by inserting (inserting) molding in the state where the pressing member stands up, the pressing member stands up until the use of the connector. In addition, since the present connector can be supplied to the user while the pressing member is standing, the user does not need to stand the pressing member in use of the connector.

Moreover, in the balanced 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 molded by insert (insert) molding, the pressing member and the terminal are fixed in the initial state, but by the configuration, in the direction in which the user knocks down the pressing member in order to use the connector. When it rotates, the adhesion surface of the said press member and the part around the axial hole of the said terminal will fall, and once a adhesion surface falls, both members will advance in the direction which falls by the said inclination, and a friction force does not generate | occur | produce. Therefore, with this configuration, it is possible to release the pressing member and the terminal from sticking with a small force.

Moreover, in the said structure, when the said axial part sees the said axial part from the axial direction, the protrusion amount of the protrusion part which protrudes to the opposite side to the operation part by fitting the said axial part in the position which overlaps with the axial part of the said terminal, It is preferable that it is narrower than the minimum width when it sees from an axial direction. When the protrusion amount of the protruding portion is small, the contact resistance with the bearing portion at the time of rotating the pressing member becomes small, so that the operation of the pressing member is smooth.

Moreover, in the connector for balanced conductors of this invention, it is preferable that the center of the said axial hole is offset to the said contact part side with respect to the circular arc center of the circular-arc part of the said bearing part. According to this configuration, when the pressing member is rotated when the connector of the present invention is used, the fixing portion between the bearing part and the pressing member is peeled off the contact portion side by the offset, so that the user When rotating the pressing member, it is possible to rotate with a light force.

Moreover, in the connector for balanced conductors of this invention, the slit opened to the outer periphery of the said bearing part is provided in the said shaft hole, and the said slit is closed at the time of insertion (insert) molding by the said metal mold | die. It is preferable to open after insert (insert) molding. With this configuration, when insertion (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 fixed portion between the bearing portion and the pressing member is reduced. Becomes smaller. Therefore, the user can rotate with a light force when rotating the pressing member.

Moreover, in the connector for balanced conductors of this invention, it is preferable that the said slit is opened toward the said contact part side from the said axial hole. According to this configuration, when the pressing member presses the balanced conductor, the force generated in the shaft portion of the pressing member is applied to the opposite side of the slit, so that the slit does not open or deform.

Moreover, in order to achieve the said objective, the manufacturing method of the connector for balanced conductor connection of this invention is a manufacturing method of the connector for balanced conductor connection of Claim 1, Comprising: The said mold is for the housing which forms the said housing. A cavity, a housing injection hole for injecting molten resin into the housing cavity, a press member cavity for molding the press member, a press member injection hole for injecting molten resin into the press member cavity, and A terminal mounting step of mounting a terminal to the terminal housing in a state in which the mold is opened, and closing the mold to inject molten resin into the housing cavity and the pressing member cavity; And an injection step, wherein in the injection step, the injection hole for the pressing member melts toward the shaft hole of the terminal. Characterized in that the injection and filling a molten resin outlet by the operation unit side from the shaft portion side of the image.

In this way, when the molten resin is injected from the pressing member injection port toward the shaft hole of the terminal, when the molten resin is cooled and solidified, the so-called sink mark in which the resin shrinks is closer to the axis than the ejected axial direction. The radial direction becomes large. As a result, the outer diameter of the shaft portion of the pressing member becomes smaller with respect to the inner diameter of the shaft hole of the terminal, so that the rotational operation of the pressing member is smooth.

Moreover, in the manufacturing method of the balanced conductor connection connector of this invention, it is preferable that the said press member cavity is a shape of the said press member standing up with respect to the said housing. By making the press member cavity into such a shape, the product after the insert (insert) molding is in a state in which the press member stands. Therefore, the user does not need to stand the pressing member when using the connector.

In addition, the manufacturing method of the connector for balanced conductor connection of the present invention is the method for manufacturing the connector for balanced conductor connection according to claim 6 or 7, wherein the mold presses the bearing part when the mold is closed. And a closing member for closing the slit. The slit of the shaft hole is closed at the time of insertion (insert) molding by the closing member, and after opening the mold, the slit is opened by the elasticity of the bearing part. Therefore, after the insert (insert) molding, the fixing portion between 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 member becomes easy.

In addition, in FIG.4 (b), the state which the press member 5 fell in the direction which presses FPC6 is shown by the dashed-dotted line.

Next, the manufacturing method of the connector of this embodiment is demonstrated. The manufacturing method of the connector of this embodiment becomes from a terminal formation process, a terminal installation process, and an injection process, and various processes are performed with the metal mold | die 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 anisotropic pin 74. The upper mold 71 is movable and the lower mold 72 is fixed. The upper die 71, the lower die 72 and the slide core 73 form a cavity 75 of a shape corresponding to the connector. As shown in Fig. 5 (b), the cavity 75 is cut in the shape of the press member cavity 75a cut into the shape of the press member 5 and the shape of the housing 4. It has a housing | casing cavity 75b. In the cavity 75 of the lower die 72, a terminal housing portion 76 in 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 | type 71 and the lower mold | type 72 is a parting line. In addition, the anchor pin 74 is fixed to the upper mold 71 by the plate 71a so as to be integral with the upper mold 71 and move up and down. Moreover, the plate 71a is provided with the press block 71b of a large shape. This pressing block 71b presses the inclined surface of the left end of the slide core 73 in FIG. 5A when the mold 7 is closed, and slides the slide core 73 to the right in the drawing. .

As shown in FIG. 5 (b), the upper die 71 is supplied with an injection port 77 for pressing members for injecting molten resin serving as the pressing member 5 and a molten resin. A pressurizing member runner 78, a housing injection hole 79 for injecting molten resin into the housing 4, a housing runner 80, a pressurizing member runner 78 and a housing runner ( The spool 81 which supplies resin to 80 is provided. The pressing member injection port 77 is provided at a position at which the molten resin is injected toward the shaft holes 24 and 34 of the first terminal 2 and the second terminal 3. Further, the housing injection port 79 is provided at a position at which the molten resin is injected toward the fixing holes 25 and 35 of the first terminal 2 and the second terminal 3. In addition, in the metal mold | die 7 in this embodiment, as shown to FIG. 5 (a) and (b), the press member cavity so that the press member 5 may stand up with respect to the housing 4. 75a and the housing cavity 75b are formed.

In addition, as shown in FIG. 6, in the present embodiment, a pair of cavities 75 are formed to the left and right so that two connectors 1 can be molded by one mold 7. As shown in FIG. 6, the molten resin supplied into the spool 81 is used for the left and right pressing member injection holes 77 and the housing through the pressing member runner 78 and the housing runner 80. It is injected from the injection port 79 into the pressing member cavity 75a and the housing cavity 75b.

In the manufacturing method of this embodiment, first, in the terminal forming step, the metal plate is pressed by a known punch press not shown in the drawing to form the first terminal 2 and the second terminal 3. At this time, press working is performed so that burrs do not remain in the bearing parts 23 and 33 and the shaft holes 24 and 34. The 1st terminal 2 and the 2nd terminal 3 formed in this way are oriented by the well-known aligner not shown in the figure, and the 1st terminal 2 and the 2nd terminal 3 alternately at the same time. It is arrange | positioned so that it may be conveyed to the metal mold | die 7 with which the next terminal installation process is performed.

In the terminal mounting step, as shown in FIG. 7A, the first terminal 2 and the first terminal 2 formed in the terminal forming step with the upper mold 71 and the lower mold 72 of the mold 7 open. The two terminals 3 are set in the terminal storage part 76 provided in the cavity 75 of the metal mold | die 7 with the conveyer which is not shown in figure.

Next, as shown in FIG.7 (b), the upper mold | type 71 approaches the lower mold | type 72, and frame closing is performed. When the upper die 71 descends, the slide core 73 moves to the right in FIG. Then, when the upper mold 71 and the lower mold 72 are closed, the slide core 73 slides by the pressing block 71b, and the comb-shaped portion of the tip of the slide core 73 is formed at each terminal. It is inserted in between, and the cavity 75 is formed by the upper mold | type 71, the lower mold | type 72, and the slide core 73. As shown in FIG.

In the injection process, 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 75a is passed through the spool 81 and the pressing member runner 78 from the pressing member injection port 77 by the first terminal 2 and the second. It is injected toward the shaft holes 24 and 34 of the terminal 3. As a result, in the cavity 75a for the pressing member, resin is first 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, Resin flows toward the protrusion part 54 and the operation part 51, and resin is filled in the press member cavity 75a.

The molten resin injected into the housing cavity 75b of the first terminal 2 and the second terminal 3 from the housing injection port 79 through the spool 81 and the pressure housing runner 80. It is injected toward the fixing holes 25 and 35. Thereby, in the housing cavity 75b, the molten resin is filled in the fixing holes 25 and 35, resin flows to the other part after that, and resin is filled in the housing cavity 75b.

In this manner, after the molten resin is filled in each cavity, the molten resin solidifies and waits until the mold can be opened. Then, the mold 7 is opened to remove the connector 1 from the mold 7. . By the above process, the connector 1 of this embodiment is manufactured.

The connector 1 manufactured by the said process is supplied to the user, such as an electric equipment maker, in the state which the pressing member 5 stood up. The user mounts the connector 1 on the printed wiring board which is not shown in figure, for example. And when connecting the connector 1 and the FPC 6, the connection part 26 of the FPC 6 enters from the front of the connector 1, and the 1st terminal 2 and the 2nd terminal 3 of It is inserted between the arm parts 22 and 32 and the contact parts 21 and 31. Thereafter, the worker knocks down the pressing member 5 on the FPC 6 side and connects the FPC 6 and the connector 1 to each other. In this way, the user does not need to stand the pressing member 5 in the connection between the connector 1 and the FPC 6 as in the prior art, so that the connection work can be easily performed.

At this time, the bearing parts 23 and 33 of the 1st terminal 2 and the 2nd terminal 3 have the plate | board thickness of the FPC6 side from the upper part as shown in FIG.4 (a). Since the pressing member 5 is rotated to the FPC 6 because the pressing member 5 is rotated slightly downward, the close contact portions around the bearing 23 and 33 and the shaft 52 of the pressing member 5 are peeled off. After that, the pressing member 5 can be rotated smoothly. In addition, since the center C of the arc portions 23a and 33a of the bearing parts 23 and 33 and the center C 'of the shaft holes 24 and 34 are offset, when the pressing member 5 is rotated, the bearing parts 23 and 33 are rotated. In the lower left direction (offset direction) of 33), the fixing portion between the outer circumferential surface of the shaft portion 52 of the pressing member 5 and the inner circumferential surface of the shaft holes 24 and 34 is peeled off, so that the rotational operation of the pressing member 5 is performed. This becomes light.

In addition, in the said embodiment, although the 1st terminal 2 and the 2nd terminal 3 are made into the shape as shown in FIG. 2, the bearing part which holds the axial part 52 of the press member 5 ( If the 23 and the shaft hole 24 are provided, the shape of the other part can be appropriately changed in response to the user's request. In the manufacture of the connector 1, the pressing member 5 is erected (inserted) by standing upright at a right angle with respect to the housing 4 of the connector 1, but the user is not limited to this. (6) The angle may be slightly different if the trouble of standing up is reduced when connecting lights. 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. However, this is not the only limitation. It may be offset and may be offset only downward.

Next, the connector 1A of 2nd Embodiment of this invention is demonstrated with reference to FIG. The connector 1A of the second embodiment is shown in FIG. 8A 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 described above, the slits 27 and 37 opened downward are provided. These slits 27 and 37 are formed to widen downward. FIG. 8B shows a state where the terminals 2 and 3 in the mold 7 are accommodated. The metal mold | die 7 is equipped with the closing member 73a which presses the bearing parts 23 and 33 and closes the slits 27 and 37 at the time of closing a mold. The closing member 73a is fixed to the slide core so as to work integrally with the slide core 73 (see FIG. 7). In addition, since it is the same as that of the said embodiment about another structure, detailed description is abbreviate | 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 provided in the terminal housing portion 76 in the mold 7. At this time, the bearing parts 23 and 33 of both terminals are in the state which the slit 27 and 37 open | release, as shown to FIG. 8 (a). When the mold closing of the mold 7 is performed from this state, as shown in Fig. 8B, the closing member 73a, which is integrated with the slide core 73, has the bearing parts 23 and 33 of the terminal. When the mold is closed and the closing of the mold is completed, as shown in FIG. 8C, the bearing parts 23 and 33 are pressed by the closing member 73a to close the slits 27 and 37.

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 opening of the mold 7 is performed after the molten resin solidifies, as shown in Fig. 8 (d), the closing member 73a is separated from the bearing parts 23 and 33. Then, since the bearing parts 23 and 33 return to the original state by the elasticity of the bearing parts 23 and 33 themselves, the diameter of the shaft holes 24 and 34 becomes wider than when closing a frame. Thereby, the surface of the inner peripheral surface of the bearing parts 23 and 33 and the shaft part 52 of the press member 5 peels, and a clearance gap arises.

Since the connector 1A of the second embodiment has the above-described configuration, when the user rotates the pressing member 5 when the user uses the connector 1A, the inner circumferential surface of the bearing parts 23 and 33 and the shaft part ( Since a part of the outer peripheral surface of 52) is peeled off, the pressing member 5 can be rotated with a light force.

In addition, in the said 2nd Embodiment, although the slit 27 and 37 are provided in the downward direction of the axial hole 24 and 34, you may provide above and may be provided in the front.

Next, the connector 1B of the third embodiment of the present invention will be described with reference to FIG. 9. As for the bearing parts 23 and 33 of the connector 1B of 3rd Embodiment, as shown in FIG.9 (a), the axial hole 24 and 34 are circular arc part 23a of the bearing part 23 and 33, It is largely offset downward from the center of 33a), and the slits 28 and 38 are provided large toward the downward direction. In addition, on the upper surface of the slide core 73 of the mold 7, a large projection 73b is provided in accordance with the shapes of the slits 28 and 38. In addition, since it is the same as that of the said embodiment about another structure, detailed description is abbreviate | omitted.

The manufacturing process of the connector 1B of 3rd Embodiment is as follows. First, in the terminal installation step, the first terminal 2 and the second terminal 3 are provided in the terminal housing portion 76 in the mold 7. At this time, the bearing parts 23 and 33 of both terminals are in the state which the slit 28 and 38 opened, as shown to FIG. 9 (a). When the mold 7 is closed from this state, as shown in Fig. 9B, the slide core 73 approaches the bearing 23, 33 of the terminal, and the slide core 73 is further closed. When it moves to the right in FIG. 9 (b), the lower end parts 23f and 33f in front of the bearing parts 23 and 33 climb on the projection 73b and lift upwards, and the slide core 73 is further moved. When moved, the projection 73b is fitted to the slits 28 and 38, and the shaft holes 24 and 34 are closed.

Next, when the mold opening of the mold 7 is performed after the molten resin is solidified, as shown in Fig. 9 (d), the lower end portions 23f and 33f of the water bearing portions 23 and 33 are protrusions 73b. Is moved in the opening direction, and the surface of the inner circumferential surfaces of the bearing parts 23 and 33 and the shaft part 52 are peeled off. After that, when the slide core 73 is further moved, the engagement between the lower end portions 23f and 33f of the bearing portions 23 and 33 and the projection 73b is separated, and the lower end portion is caused by the elasticity of the bearing portions 23 and 33 itself.
