[0022] [Details of Embodiments of the Invention] <Implementation Method 1> Reference Figures 1 to 11 A connector 10 that embodies the present invention will be described. In the figure, "front side", "rear side", "upper side", "lower side", "right side" and "left side" are represented by "F", "B", "U", "D", "R" and "L", respectively. In the first embodiment, the left-right direction corresponds to the width direction.

[0023] The connector 10 of this embodiment is mounted on a flexible cable 30, which is a flexible substrate to which a reinforcing plate 50 as a supporting member is attached. The connector 10 includes a housing 11, a plurality of terminal parts 12, the flexible cable 30, the reinforcing plate 50 as a supporting member, an outer cover 20, a guide portion 20G, a protective member 70, and a waterproof member 60.

[0024] <Housing> The housing 11 is made of synthetic resin. Figure 1 As shown, the housing 11 is in a block shape that is long in the width direction (left-right direction). A plurality of cavities 11A are formed in the interior of the housing 11 along the front-back direction, and the plurality of cavities 11A are used to accommodate the terminal parts 12 described later. The opening 11B at the front end of each cavity 11A functions as an insertion hole for inserting the terminal on the other side.

[0025] like Figure 2 As shown, a pair of cylindrical pins 11C extending backward are provided on the rear end surface of the housing 11. One pin 11C is arranged at the left end of the housing 11, and the other pin 11C is arranged at the center of the housing 11 in the left-right direction. The outer diameter of the other pin 11C is larger than the outer diameter of the one pin 11C.

[0026] <Terminal parts> The terminal part 12 is formed by punching a metal plate into a predetermined shape and then bending it. Figure 1 As shown, the terminal part 12 has a square tube portion 12A and an insertion portion 12B. The square tube portion 12A extends in a square tube shape in the front-to-back direction, and contains a contact piece (not shown) that contacts the protrusion (not shown) of the terminal part on the other side. The insertion portion 12B is provided at the rear end of the terminal part 12. The insertion portion 12B is formed to extend slenderly from the square tube portion 12A toward the rear.

[0027] Each terminal part 12 is inserted into each cavity 11A of the housing 11 from the rear. Figure 3 As shown, the terminal parts 12 inserted into each cavity 11A are stopped at the front end of each cavity 11A. The insertion portion 12B of each terminal part 12 that is stopped at the front is in a state of protruding further back than the rear end of the housing 11. In each terminal part 12, the rear end (top end) of the insertion portion 12B protruding further back than the rear end of the housing 11 is a connection portion 12C welded to a welding surface 30A of a flexible cable 30 described later. In this way, the relative positions of the plurality of terminal parts 12 are determined by being housed in the housing 11.

[0028] <Flexible Cable> The flexible cable 30 is a cable exemplified as an FFC (Flexible Flat Cable) or FPC, and has flexibility (deformability) that allows it to be easily deformed by an external force. The flexible cable 30 is provided with a plurality of wiring patterns (not shown) and is in the shape of a strip that is long in the vertical direction with the plate thickness direction facing the front-rear direction. Figure 4 As shown in FIG. 1 , the front surface of the flexible cable 30 is a plate surface 30F, and the rear surface is another plate surface 30E. At the top end of the other plate surface 30E of the flexible cable 30, the ends of each wiring pattern are exposed to form a plurality of soldering surfaces 30A. These soldering surfaces 30A are arranged in the width direction (left-right direction). These soldering surfaces 30A are connected to the connection portion 12C of the terminal component 12 (see FIG. 1 ) by solder. Fig.11 ).

[0029] A plurality of through holes 30B and two insertion holes 30C are formed in the plate thickness direction at the top end of the flexible cable 30. Each through hole 30B is formed to penetrate each welding surface 30A in the plate thickness direction. In other words, each through hole 30B is formed at a position corresponding to each welding surface 30A.

[0030] The two insertion holes 30C are arranged one at each of the two ends in the width direction of the belt (the two ends in the left-right direction). The two insertion holes 30C are arranged at a position farther from the tip of the flexible cable 30 than the plurality of through holes 30B.

[0031] <Reinforcement Plate> The reinforcing plate 50 is formed into a flat plate using glass epoxy resin or polyimide resin. The thickness of the reinforcing plate 50 is thicker than that of the flexible cable 30. Figure 1 As shown in FIG. 1 , a plurality of reinforcing plate side through holes 50A as through holes, two reinforcing plate side insertion holes 50B as insertion holes, and two positioning holes 50C are formed in the reinforcing plate 50 along the plate thickness direction. The reinforcing plate side through holes 50A are arranged corresponding to the plurality of through holes 30B of the flexible cable 30. The two reinforcing plate side insertion holes 50B are arranged corresponding to the two insertion holes 30C of the flexible cable 30. The inner diameter of the reinforcing plate side insertion hole 50B is slightly larger than the inner diameter of the insertion hole 30C (see FIG. 1 ). Figure 5 ). One of the two positioning holes 50C is arranged at the left end of the reinforcing plate 50, and the other is arranged at the center in the left-right direction. The inner diameter of one positioning hole 50C is smaller than the inner diameter of the other positioning hole 50C.

[0032] like Figure 5 , 6As shown, the reinforcing plate 50 is attached to one side plate surface 30F of the top end portion of the flexible cable 30 using an adhesive. The adhesive is not shown. As a result, the top end portion of the flexible cable 30 is reinforced. The front surface of the reinforcing plate 50 attached to one side plate surface 30F of the flexible cable 30 is a mounting surface 50D, and the mounting surface 50D constitutes a part of the one side plate surface 30F of the flexible cable 30. In other words, the flexible cable 30 has a mounting surface 50D. The mounting surface 50D faces forward. The mounting surface 50D is an exposed surface that is not attached to the one side plate surface 30F of the flexible cable 30. In the flexible cable 30, the portion extending downward from the reinforcing plate 50 is an extension portion 30D (see Figure 5 The extension portion 30D is connected to the mounting surface 50D and extends downward.

[0033] like Figure 6 As shown in the figure, in the reinforcing plate 50 attached to the one side plate surface 30F of the flexible cable 30, each reinforcing plate side through hole 50A is connected to each through hole 30B. Each reinforcing plate side insertion hole 50B is connected to each insertion hole 30C. The rear end (one end) of each positioning hole 50C is closed by the one side plate surface 30F of the flexible cable 30.

[0034] like Figure 7 As shown, the housing 11 into which the terminal parts 12 are inserted is mounted on the mounting surface 50D of the reinforcing plate 50 attached to the flexible cable 30. Specifically, the connection portion 12C of the insertion portion 12B of each terminal part 12 is inserted into the reinforcing plate side through hole 50A and through hole 30B from one side of the plate surface 30F. At the same time, a pair of pins 11C are inserted into the positioning holes 50C of the reinforcing plate 50 from one side of the plate surface 30F. The outer diameter of the pins 11C is set to be slightly smaller than the inner diameter of the inserted positioning holes 50C. When the rear end of the housing 11 contacts the mounting surface 50D of the reinforcing plate 50, the mounting of the housing 11 to the reinforcing plate 50 is completed.

[0035] In a state where the rear end of the housing 11 is in contact with the front surface (mounting surface 50D) of the reinforcing plate 50, the pair of pins 11C are retracted into the positioning holes 50C. The connection portion 12C of the insertion portion 12B of each terminal part 12 protrudes to the rear of the other plate surface 30E of the flexible cable 30. In this state, the connection portion 12C is welded to the welding surface 30A provided on the other plate surface 30E of the flexible cable 30. The pair of pins 11C are retracted into the positioning holes 50C and are not exposed on the other plate surface 30E side of the flexible cable 30. Therefore, the pair of pins 11C are not exposed by the heat of the molten solder, and the function of positioning the housing 11 relative to the flexible cable 30 is not impaired.

[0036] <Outer cover> The outer cover 20 is made of synthetic resin. Figure 1As shown, the outer cover 20 includes a cover body portion 20A that accommodates the housing 11 from the front and a cover portion 20C that covers the reinforcing plate 50 .

[0037] The cover body 20A is formed to extend rearward in a square tube shape from the outer peripheral edge of the front wall 20B with the plate thickness direction oriented in the front-rear direction. The front wall 20B has a plurality of protrusion insertion holes 20N formed therethrough in the plate thickness direction (front-rear direction) corresponding to the cavities of the housing 11.

[0038] The cover portion 20C is formed so as to extend from the rear end portion of the cover body portion 20A in a direction perpendicular to the front-rear direction. Fig.10 As shown, the covering portion 20C has an upper wall portion 20M, two welding pins 20D and two claws 20F. The upper wall portion 20M is in the shape of a plate and is arranged to extend backward from the upper end edge of the covering portion 20C extending in the left-right direction. Side wall portions 20E in the shape of a plate and extending downward with the plate thickness direction facing the left-right direction are arranged at both ends of the upper wall portion 20M in the left-right direction. A claw portion 20F is provided on each side wall portion 20E. These claw portions 20F protrude from the inner surface of each side wall portion 20E in the left-right direction toward the inner side in the left-right direction. The two welding pins 20D are cylindrical. These welding pins 20D are arranged one at each end of the left-right direction of the covering portion 20C and extend backward. The welding pins 20D are arranged below the cover body 20A.

[0039] <Guide> The guide portion 20G has a function of guiding the extension portion 30D of the flexible cable 30. The guide portion 20G is integrally connected to the lower edge of the cover portion 20C of the outer cover 20 and extends rearward. On the upper surface of the guide portion 20G, a first inclined surface 20H, a connecting surface 20J, a second inclined surface 20K, and a parallel surface 20L are sequentially formed in a continuous manner. The first inclined surface 20H is continuous with the rear side of the lower edge of the cover portion 20C and is formed to be inclined rearward and downward. The connecting surface 20J is continuous with the rear end of the first inclined surface 20H and is formed to extend downward. The second inclined surface 20K is continuous with the lower end of the connecting surface 20J and is formed to be inclined rearward and downward. The parallel surface 20L is continuous with the rear end of the second inclined surface 20K and is formed to extend rearward in parallel with respect to the front-rear direction.

[0040] like Fig.11 As shown, the angle θ1 formed by the first inclined surface 20H with respect to the imaginary line V1 extending in the front-back direction is greater than the angle θ2 formed by the second inclined surface 20K with respect to the imaginary line V2 extending in the front-back direction. Here, the imaginary line V1 and the imaginary line V2 are parallel. The first inclined surface 20H and the second inclined surface 20K are formed in a step shape by the connecting surface 20J.

[0041] The outer cover 20 accommodates the housing 11 in a state where the flexible cable 30 is installed from the front, and is installed on the flexible cable 30 from the side of the one plate surface 30F. Specifically, the outer cover 20 is placed in a posture such that the guide portion 20G and the upper wall portion 20M are located behind the cover body portion 20A, and the guide portion 20G is located below the upper wall portion 20M. In addition, the cover body portion 20A is brought close to the housing 11 from the front to cover it. At this time, the extension portion 30D of the flexible cable 30 is pressed backward by the guide portion 20G and bent backward from the mounting surface 50D. In addition, the front surface (mounting surface 50D) of the reinforcing plate 50 is covered by the covering portion 20C.

[0042] like Figure 7 As shown, a pair of claws 20F are respectively locked at the two end edges in the left and right directions of the other side plate surface 30E of the flexible cable 30. At the same time, a pair of welding pins 20D are inserted through each reinforcing plate side insertion hole 50B and each insertion hole 30C (see Figure 8 , 9 ), and is in a state of protruding toward the other plate surface 30E side of the flexible cable 30. And, each welding pin 20D protruding toward the other plate surface 30E side is compressed and deformed into an umbrella shape W while being heated by the welding iron. In this way, each welding pin 20D is welded to the flexible cable 30.

[0043] <Waterproof components> The waterproof member 60 is made of synthetic resin such as silicone resin or resin. The waterproof member 60 is concealed in a manner that does not expose the entirety of the welding surface 30A and the connection part 12C. The waterproof member 60 is applied to the welding surface 30A and its periphery where the connection part 12C is welded in a fluid state. Then, the applied waterproof member 60 is cured by being irradiated with electromagnetic waves such as ultraviolet rays or infrared rays. The cured waterproof member 60 has a function of preventing liquid from adhering to the connection part 12C or the welding surface 30A.

[0044] <Protective components> The protection member 70 is made of synthetic resin. Figure 1 As shown, the protection member 70 is formed long in the left-right direction. The protection member 70 has a pair of locking wall portions 70A and a guide wall portion 70B. The pair of locking wall portions 70A extend forward from both ends in the left-right direction. A claw portion 70C protruding inward in the left-right direction is provided at the front end of the locking wall portion 70A.

[0045] The guide wall portion 70B has a width in the left-right direction, and extends forward continuously from the lower end edge extending in the left-right direction of the protection member 70. Fig.11 As shown in FIG. 1 , the lower surface of the guide wall portion 70B is formed to be inclined forward and upward. A convex portion 70D formed to protrude downward is provided at the front portion of the lower surface of the guide wall portion 70B. The convex portion 70D is in the shape of a rib that is long in the left-right direction (see FIG. 1 ). Figure 1 The lower end surface of the protrusion 70D is inclined forward and upward.

[0046] The protective member 70 covers the welding surface 30A from the rear and is assembled from the other plate surface 30E side of the flexible cable 30. The protective member 70 is inserted between the guide portion 20G and the upper wall portion 20M from the rear. At this time, the extension portion 30D of the flexible cable 30 is sandwiched by the guide wall portion 70B and the guide portion 20G, and the extension portion 30D is led out to the rear from between the guide wall portion 70B and the guide portion 20G. The extension portion 30D is located below the guide wall portion 70B and above the guide portion 20G.

[0047] Each locking wall portion 70A protrudes from the other plate surface 30E side across the flexible cable 30 toward the front of the one plate surface 30F, and each claw portion 70C is locked with a locked portion 20Q formed on the outer cover 20 (see Figure 7 Each locking wall portion 70A is locked to the outer cover 20 from the rear with the mounting surface 50D interposed therebetween (see Figure 7 ).

[0048] The convex portion 70D of the guide wall portion 70B contacts the extension portion 30D of the flexible cable 30 bent backward from above. Specifically, the lower end of the convex portion 70D contacts the plate surface connected to the other plate surface 30E provided with the welding surface 30A. The lower end of the convex portion 70D is the protection member side contact portion 70E that contacts the extension portion 30D. On the other hand, the parallel surface 20L of the guide portion 20G contacts the plate surface connected to the one plate surface 30F to which the reinforcing plate 50 is attached. The parallel surface 20L is the guide portion side contact portion 20P that contacts the extension portion 30D. When the protection member 70 is mounted on the outer cover 20, the convex portion 70D is located forward of the rear end of the guide portion 20G. In other words, when the protection member 70 is mounted on the outer cover 20, the protection member side contact portion 70E is located forward of the guide portion side contact portion 20P. In a state where the protection member 70 is locked to the outer cover 20 , the guide portion 20G is disposed at a position adjacent to a lower side (a direction intersecting the front-rear direction) of the protection member 70 .

[0049] Next, the operation of the first embodiment will be described. The connector 10 includes a housing 11, a plurality of terminal parts 12, a flexible cable 30, and a reinforcing plate 50. The plurality of terminal parts 12 are positioned by being accommodated in the housing 11. A connection portion 12C of the terminal part 12 protruding from the housing 11 is welded to the flexible cable 30. The reinforcing plate 50 is attached to one plate surface 30F of the flexible cable 30. A through hole 30B penetrating in the plate thickness direction is formed in the flexible cable 30.

The guide portion 20G is provided integrally with the cover 20. According to this structure, the extension portion 30D is bent after the housing 11 is substantially mounted on the flexible cable 30, so that the housing 11 can be prevented from being mounted on the flexible cable 30 in a floating state.

[0058] The connector 10 includes a protective member 70, and the protective member 70 is locked to the outer cover 20 from the rear with the mounting surface 50D interposed therebetween. When the protective member 70 is locked to the outer cover 20, the guide portion 20G and the protective member 70 are adjacent to each other in a direction intersecting the front-rear direction, and the extension portion 30D is led out to the rear from between the guide portion 20G and the protective member 70. The guide portion 20G is provided with a guide portion side contact portion 20P with which the extension portion 30D contacts, and the protective member 70 is provided with a protective member side contact portion 70E with which the extension portion 30D contacts, and the protective member side contact portion 70E is located forward of the guide portion side contact portion 20P. According to this structure, the protective member side contact portion 70E makes it easy to maintain the state in which the extension portion 30D contacts the guide portion side contact portion 20P, thereby making it easy to stabilize the direction in which the extension portion 30D is led out to the rear.
