[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The connector disclosed herein is (1) First flexible cable and The second flexible cable, A housing into which the first flexible cable and the second flexible cable are inserted from the rear, Equipped with, The aforementioned housing is A first cavity housing the first flexible cable, A second cavity provided at a distance from the first cavity and housing the second flexible cable, A first lance protrudes from the second cavity into the first cavity and locks onto the first flexible cable, A second lance protrudes from the first cavity into the second cavity and engages with the second flexible cable, It has, The housing is provided with a flex space into which the first lance and the second lance can be retracted.

[0010] According to the configuration of the above (1), when the first flexible cable is inserted into the first cavity, the first lance is pushed by the first flexible cable and retracts into the deflection space, and when the first flexible cable is properly inserted, the first lance elastically returns and locks to the first flexible cable. When the second flexible cable is inserted into the second cavity, the second lance is pushed by the second flexible cable and retracts into the above deflection space, and when the second flexible cable is properly inserted, the second lance elastically returns and locks to the second flexible cable. In this way, since one deflection space can be shared for the retraction of the first lance and the retraction of the second lance, the height of the housing can be reduced compared to a configuration in which separate deflection spaces are provided for retraction of each lance, and consequently the height of the connector device can be reduced.

[0011] (2) In the connector according to the above (1), A mating housing that fits into the housing is provided, It is preferable that the mating housing has a deflection restricting portion that enters the deflection space in a state of being fitted to the housing.

[0012] According to the configuration of the above (2), the first lance and the second lance are restricted from retracting into the deflection space by interfering with the deflection restricting portion that has entered the deflection space. Thereby, it is possible to prevent each lance from being unintentionally deflected by vibration or the like and releasing the locking with each flexible cable. Therefore, it is possible to prevent each flexible cable from unintentionally slipping out of each cavity.

[0013] (3) In the connector according to the above (1) or (2), The housing comprises a pair of the first lances arranged spaced apart in the width direction orthogonal to the front-rear direction, and a pair of the second lances arranged spaced apart in the width direction, , First locking holes for locking with the first lances are provided at both ends in the width direction of the first flexible cable, It is preferable that the second flexible cable has second locking holes at both ends in the width direction, into which the second lance engages.

[0014] According to the configuration described in (3) above, both ends of the first flexible cable in the width direction can be secured by different first lances. Both ends of the second flexible cable in the width direction can be secured by different second lances. Therefore, the flexible cable can be stably supported by the housing.

[0015] (4) In any of the connectors described in (1) to (3) above, A first recess is provided in the wall of the first cavity opposite to the second cavity, into which the protruding end of the first lance fits. Preferably, a second recess is provided in the wall of the second cavity opposite to the first cavity, into which the protruding end of the second lance fits.

[0016] According to the configuration described in (4) above, by providing recesses in the housing, it is not necessary to create a structure that avoids interference with the protruding ends of each lance (for example, a structure that increases the size of the cavity), and the housing can be made lower in profile.

[0017] [Details of the embodiments of this disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. However, the present invention is not limited to these examples and is intended to be included in the claims, with all modifications in the sense and scope equivalent to the claims.

[0018] <Embodiment 1> Embodiment 1 of the connector of this disclosure will be described with reference to Figures 1 to 7. As shown in Figure 1, the connector device C comprises a connector 10 and a mating connector 110. The connector 10 and the mating connector 110 are mated with each other.

[0019] In this embodiment 1, the "front," "rear," "upper," "lower," "right," and "left" sides in Figure 1 are represented by "F," "B," "U," "D," "R," and "L," respectively. In the following description, the direction in which connector 10 and mating connector 110 are mated is defined as the mating direction (front-to-back direction). In this embodiment 1, the left-to-right direction corresponds to the width direction and is the direction that intersects the mating direction.

[0020] As shown in Figures 1 and 2, the connector 10 comprises a first flexible cable 20, a second flexible cable 30, and a housing 40.

[0021] [Configuration of the first flexible cable] As shown in Figure 2, the first flexible cable 20 has a substrate 21 and a reinforcing plate 22. The substrate 21 is made of what is known as FPC (Flexible Printed Circuits). The substrate 21 has flexibility (deformability) that allows it to be easily deformed when subjected to external forces. Multiple wiring patterns 23 are provided on one surface of the substrate 21. As shown in Figure 2, the ends of the wiring patterns 23 are formed as multiple contact portions 24. These contact portions 24 are formed in the width direction (left-right direction).

[0022] The reinforcing plate 22 has a greater thickness than the substrate 21 and does not easily deform even when subjected to external forces. In other words, the reinforcing plate 22 has the function of preventing the substrate 21 from being unintentionally deformed.

[0023] The first flexible cable 20 is provided with a pair of first locking holes 25 into which the first lance 41, described later, engages. The pair of first locking holes 25 are provided at both ends of the first flexible cable 20 in the width direction (left-right direction). Note that in Figure 2, only the right-side first locking hole 25 is shown. The first locking holes 25 are provided behind the contact portion 24 in the first flexible cable 20. The first locking holes 25 penetrate the first flexible cable 20 in the thickness direction and are open to the outside in the width direction.

[0024] [Configuration of the second flexible cable] As shown in Figure 2, the second flexible cable 30 has the same configuration as the first flexible cable 20. The second flexible cable 30 has a substrate 31 and a reinforcing plate 32. The substrate 31 has the same configuration as the substrate 21. The reinforcing plate 32 has the same configuration as the reinforcing plate 22. The second flexible cable 30 is provided with a plurality of wiring patterns (not shown) and a plurality of contact parts 34. The wiring patterns (not shown) have the same configuration as the wiring pattern 23. The contact parts 34 have the same configuration as the contact parts 24.

[0025] The second flexible cable 30 is provided with a pair of second locking holes 35 into which the second lance 42, described later, engages. The pair of second locking holes 35 are provided at both ends of the second flexible cable 30 in the width direction (left-right direction). The second locking holes 35 are provided behind the contact portion 34 in the second flexible cable 30. The second locking holes 35 penetrate the second flexible cable 30 in the thickness direction and are open to the outside in the width direction.

[0026] [Housing Configuration] The housing 40 is made of synthetic resin. As shown in Figures 2, 4, and 5, the housing 40 is a horizontally elongated block shape with a larger left-right dimension than its vertical dimension. As shown in Figure 4, the housing 40 has a first cavity 50 and a second cavity 60. The first flexible cable 20 is inserted into and housed in the first cavity 50 from the rear. The second flexible cable 30 is inserted into and housed in the second cavity 60 from the rear. The first cavity 50 and the second cavity 60 extend in the front-rear direction and are arranged side by side, spaced apart in the vertical direction.

[0027] The housing 40 has a first lance 41 and a second lance 42. The first lance 41 protrudes into the first cavity 50 from the second cavity 60 side (upper side) and engages with the first flexible cable 20. The second lance 42 protrudes into the second cavity 60 from the first cavity 50 side (lower side) and engages with the second flexible cable 30.

[0028] The front end of the housing 40 is provided with a plurality of first openings 43 arranged in the left-right direction. The first openings 43 are open to the front, and the first terminal fittings 120 and 2 terminal fittings 130 of the mating housing 140, which will be described later, enter into them. Behind the first openings 43 at both the left and right ends, there are second openings 44 that are connected to the first openings 43. The first lance 41 and the second lance 42 extend forward from the rear wall 44A of the second opening 44. The first lance 41 and the second lance 42 are positioned inside the second opening 44. The first lance 41 and the second lance 42 are separated in the vertical direction and have a vertically symmetrical shape.

[0029] The first cavity 50 is wide in the left-right direction and forms a rectangular space in plan view. The first cavity 50 has a bottom wall 51, an upper wall 52, left and right side walls 53, and a front wall 54.

[0030] The first lance 41 is elastically flexible in the vertical direction. The first lance 41 has an extension 41A and a projection 41B. The extension 41A has its base end connected to the rear wall 44A of the second opening 44 and extends forward in a cantilevered manner. The extension 41A is connected parallel to the upper wall 52. The projection 41B protrudes downward from a position slightly closer to the base end than the tip of the extension 41A. The projection 41B is provided with a locking surface 41C that can be contacted from the front by the edge of the first locking hole 25 of the first flexible cable 20. The locking surface 41C is cut off so as to be substantially perpendicular to the front-rear direction.

[0031] A first recess 51A is provided in the lower wall 51 in the portion facing the second opening 44, and it penetrates vertically. The protruding end 41D of the protruding portion 41B of the first lance 41 in its natural state fits into the first recess 51A. The first recess 51A is rectangular in shape when viewed from above. The first recess 51A is connected to the second opening 44 in the vertical direction.

[0032] A third recess 51B is provided in the lower wall 51 in the portion facing the first opening 43, and it penetrates vertically. The third recess 51B is open to the front. In plan view, the third recess 51B is rectangular in shape and is sized to allow the support piece 123 of the first terminal fitting 120 to fit inside. The third recess 51B is connected to the first opening 43 in the vertical direction.

[0033] The second cavity 60 is vertically symmetrical to the first cavity 50. The second cavity 60 is wide in the left-right direction and forms a rectangular space in plan view. The second cavity 60 has an upper wall 61, a lower wall 62, left and right side walls 63, and a front wall 64.

[0034] The second lance 42 is elastically flexible in the vertical direction. The second lance 42 has an extension 42A and a projection 42B. The extension 42A extends forward in a cantilevered manner, with its base end connected to the rear wall 44A of the second opening 44. The extension 42A is connected to the rear wall 44A of the second opening 44 at a position above and away from the extension 41A of the first lance 41. The extension 42A is connected parallel to the lower wall 62. The projection 42B protrudes upward from a position slightly closer to the base end than the tip of the extension 42A. The projection 42B is provided with a locking surface 42C that can be contacted from the front by the edge of the second locking hole 35 of the second flexible cable 30. The locking surface 42C is cut off so as to be substantially perpendicular to the front-rear direction.

[0035] A second recess 61A is provided in the upper wall 61 in the portion facing the second opening 44, and it penetrates vertically. The protruding end 42D of the protruding portion 42B of the second lance 42 in its natural state fits into the second recess 61A. The second recess 61A is rectangular in shape when viewed from above. The second recess 61A is connected to the second opening 44 in the vertical direction.

[0036] A fourth recess 61B is provided in the upper wall 61 in the portion facing the first opening 43, and it penetrates vertically. The fourth recess 61B is open to the front. In plan view, the fourth recess 61B is rectangular in shape and is sized to allow the support piece 133 of the second terminal fitting 130 to fit inside. The fourth recess 61B is connected to the first opening 43 in the vertical direction.

[0037] The housing 40 is provided with one flex space S into which one first lance 41 and one second lance 42 can be retracted. The flex space S is the space within the inner space of the second opening 44 that is sandwiched between the first lance 41 and the second lance 42. The flex space S is long in the front-rear direction and is open to both the front and left-right sides. The flex space S is a shared space into which the first lance 41 and the second lance 42 enter when they retract from the first cavity 50 and the second cavity 60, respectively. In the housing 40 of this embodiment 1, since there are two sets of first lances 41 and second lances 42, there are two flex spaces S.

[0038] [Assembly of flexible cables] An example of the assembly process for the first flexible cable 20 and the second flexible cable 30 will be described. When the first flexible cable 20 is inserted into the first cavity 50, it comes into contact with the protruding portion 41B of the first lance 41, as shown in Figure 6. The first lance 41 is pushed by the first flexible cable 20, deforms upward, and retracts into the deflection space S. When the first flexible cable 20 moves further forward and is inserted into the correct position, the first lance 41 elastically returns to its original position, as shown in Figure 3, and the protruding portion 41B locks into the first locking hole 25. The protruding portion 41B of the first lance 41 penetrates the first locking hole 25, and the protruding end 41D of the protruding portion 41B enters the first recess 51A, so that the first lance 41 and the first locking hole 25 are securely locked together. The front end of the first flexible cable 20 faces the front wall 54 of the first cavity 50. As a result, the first flexible cable 20 is housed in the first cavity 50. Although the operation of the first lance 41 on the right end was explained using Figure 6, the operation of the first lance 41 on the left end is performed in the same manner.

[0039] Next, when the second flexible cable 30 is inserted into the second cavity 60, it comes into contact with the protrusion 42B of the second lance 42, as shown in Figure 7. The second lance 42 is pushed by the second flexible cable 30, bends downward, and retracts into the bending space S. When the second flexible cable 30 moves further forward and is inserted into the correct position, the second lance 42 elastically returns to its original position, as shown in Figure 3, and the protrusion 42B locks into the second locking hole 35. The protrusion 42B of the second lance 42 penetrates the second locking hole 35, and the protruding end 42D of the protrusion 42B enters the second recess 61A, so that the second lance 42 and the second locking hole 35 are securely locked together. The protruding end 42D of the protrusion 42B of the second lance 42 enters the second recess 61A. The front end of the second flexible cable 30 faces the front wall 64 of the second cavity 60. As a result, the second flexible cable 30 is housed in the second cavity 60. Although the operation of the second lance 42 on the right end was explained using Figure 7, the operation of the second lance 42 on the left end is performed in the same manner.

[0040] In this way, a single deflection space S is shared during the retraction of the first lance 41 and the second lance 42. This allows the housing 40 to be made lower in height compared to a configuration in which separate deflection spaces are provided for the retraction of each lance 41 and 42.

[0041] [Configuration of the other connector] As shown in Figures 2 and 3, the mating connector 110 is, for example, a connector mounted on a circuit board 100. The mating connector 110 comprises a plurality of first terminal fittings 120, a plurality of second terminal fittings 130, and a mating housing 140. As shown in Figure 3, the first terminal fittings 120 and the second terminal fittings 130 are housed in the mating housing 140.

[0042] As shown in Figure 3, the first terminal fitting 120 has a main body 121, an elastic contact piece 122, a support piece 123, and a connecting piece 124. The main body 121 is box-shaped and open at the front and rear. The elastic contact piece 122 extends cantilevered backward from the upper wall of the main body 121. The elastic contact piece 122 has a contact portion 125 that is folded back forward and bent to protrude downward. The contact portion 125 is connected to the contact portion 24 of the first flexible cable 20. The support piece 123 extends cantilevered backward from the lower end of the main body 121. The support piece 123 contacts the first flexible cable 20 from the opposite side from the elastic contact piece 122.

[0043] The second terminal fitting 130 has a main body 131, an elastic contact piece 132, a support piece 133, and a connecting piece 134. The main body 131 is box-shaped and open at the front and rear. The elastic contact piece 132 extends cantilevered backward from the lower wall of the main body 131. The elastic contact piece 132 has a contact portion 135 that is folded back forward and bent upward. The contact portion 135 is connected to the contact portion 34 of the second flexible cable 30. The support piece 133 extends cantilevered backward from the upper end of the main body 131. The support piece 133 contacts the second flexible cable 30 from the opposite side from the elastic contact piece 132.

[0044] The mating housing 140 has a plurality of first terminal housings 141, a plurality of second terminal housings 142, and a hood portion 143. The first terminal housings 141 are into which the first terminal fittings 120 are inserted from the front and housed. The second terminal housings 142 are into which the second terminal fittings 130 are inserted from the front and housed. The plurality of first terminal housings 141 and the plurality of second terminal housings 142 are arranged in two upper and lower rows in the left-right direction at the front end portion of the mating housing 140. The plurality of first terminal housings 141 are located in the lower row. The plurality of second terminal housings 142 are located in the upper row.

[0045] The hood portion 143 forms the rear end portion of the mating housing 140 and is a rectangular tube shape that opens to the rear. The housing 40 fits into the hood portion 143. The mating housing 140 is fixed to the circuit board 100. The connection portion 124 of the first terminal fitting 120 and the connection portion 134 of the second terminal fitting 130 are electrically connected to a conductive path (not shown) of the circuit board 100.

[0046] The mating housing 140 is provided with wall portions 144 that constitute the rear wall of the first terminal housing portion 141 and the rear wall of the second terminal housing portion 142. A first recessed portion 144A that recedes forward is provided at the lower end of the wall portion 144. The first flexible cable 20 is inserted into the first recessed portion 144A. A second recessed portion 144B that recedes forward is provided at the upper end of the wall portion 144. The second flexible cable 30 is inserted into the second recessed portion 144B.

[0047] The wall portions 144 at both ends in the width direction (left-right direction) are provided with projecting deflection restricting portions 145 that extend backward. The deflection restricting portion 145 is a long, strip-shaped plate in the front-rear direction. The deflection restricting portion 145 is provided between the first recessed portion 144A and the second recessed portion 144B in the wall portion 144.

[0048] [Mating the two connectors] An example of the mating process between connector 10 and mating connector 110 will be described. When mating connector 10 and mating connector 110, the front end of connector 10 is inserted while maintaining a position where it faces directly toward the opening end of the hood portion 143 of mating connector 110. As shown in Figure 4, the first terminal fitting 120 and the second terminal fitting 130 of mating connector 110 enter into the first opening 43 of housing 40.

[0049] The front end of the first flexible cable 20 enters between the elastic contact piece 122 and the support piece 123 of the first terminal fitting 120 via the first recess 144A. The front end of the first flexible cable 20 is sandwiched above and below by the elastic contact piece 122 and the support piece 123. The contact portion 125 of the elastic contact piece 122 is connected to the contact portion 24.

[0050] As described above, the protruding portion 41B of the first lance 41 penetrates the first locking hole 25, and the protruding end portion 41D of the protruding portion 41B fits into the first recess 51A, thereby securely locking the first lance 41 and the first locking hole 25. This improves the reliability of the connection between the first flexible cable 20 and the first terminal fitting 120.

[0051] The front end of the second flexible cable 30 enters between the elastic contact piece 132 and the support piece 133 of the second terminal fitting 130 via the second recess 144B. The front end of the second flexible cable 30 is sandwiched above and below by the elastic contact piece 132 and the support piece 133. The contact portion 135 of the elastic contact piece 132 is connected to the contact portion 34.

[0052] As described above, the protruding portion 42B of the second lance 42 penetrates the second locking hole 35, and the protruding end portion 42D of the protruding portion 42B fits into the second recess 61A, thereby securely locking the second lance 42 to the second locking hole 35. This improves the reliability of the connection between the second flexible cable 30 and the second terminal fitting 130.

[0053] As shown in Figure 4, the deflection restricting portion 145 of the mating housing 140 passes through the first opening 43 of the housing 40 and then enters the second opening 44 (more specifically, the deflection space S). That is, the deflection restricting portion 145 enters between the first lance 41 and the second lance 42. The first lance 41 and the second lance 42 are prevented from retracting into the deflection space S by interfering with the deflection restricting portion 145. This prevents the lances 41 and 42 from unintentionally bending due to vibration or the like, and thus prevents the locking with the flexible cables 20 and 30 from being released.

[0054] [Effects of Embodiment 1] The connector 10 of the connector device C of this embodiment 1 comprises a first flexible cable 20, a second flexible cable 30, and a housing 40 into which the first flexible cable 20 and the second flexible cable 30 are inserted from the rear. The housing 40 has a first cavity 50 for housing the first flexible cable 20, a second cavity 60 provided spaced apart from the first cavity 50 for housing the second flexible cable 30, a first lance 41 protruding from the second cavity 60 into the first cavity 50 and engaging with the first flexible cable 20, and a second lance 42 protruding from the first cavity 50 into the second cavity 60 and engaging with the second flexible cable 30. The housing 40 is provided with a single flex space S into which the first lance 41 and the second lance 42 can be retracted.

[0055] With this configuration, when the first flexible cable 20 is inserted into the first cavity 50, the first lance 41 is pushed by the first flexible cable 20 and retracts into the flex space S, and when the first flexible cable 20 is properly inserted, the first lance 41 elastically returns and locks onto the first flexible cable 20. When the second flexible cable 30 is inserted into the second cavity 60, the second lance 42 is pushed by the second flexible cable 30 and retracts into the flex space S, and when the second flexible cable 30 is properly inserted, the second lance 42 elastically returns and locks onto the second flexible cable 30. In this way, since the retraction of the first lance 41 and the retraction of the second lance 42 can share one flex space S (flex allowance), the housing 40 can be made lower in height compared to a configuration in which separate flex spaces S are provided for the retraction of each lance 41 and 42, and consequently the connector device C can be made lower in height.

[0056] In the connector 10 of this embodiment 1, a mating housing 140 is provided that fits into the housing 40. The mating housing 140 has a deflection restricting portion 145 that enters into the deflection space S when fitted into the housing 40. With this configuration, the first lance 41 and the second lance 42 are restricted from retracting into the deflection space S by interfering with the deflection restricting portion 145 that enters into the deflection space S. This prevents the lances 41 and 42 from unintentionally bending due to vibration or the like, and releasing their engagement with the flexible cables 20 and 30. Therefore, it is possible to prevent the flexible cables 20 and 30 from unintentionally coming out of the cavities 50 and 60.

[0057] In the connector 10 of this embodiment 1, the housing 40 has a pair of first lances 41 spaced apart in the width direction perpendicular to the front-rear direction, and a pair of second lances 42 spaced apart in the width direction. First locking holes 25 are provided at both ends in the width direction of the first flexible cable 20, into which the first lances 41 engage. Second locking holes 35 are provided at both ends in the width direction of the second flexible cable 30, into which the second lances 42 engage. With this configuration, both ends in the width direction of the first flexible cable 20 can be locked by different first lances 41. Both ends in the width direction of the second flexible cable 30 can be locked by different second lances 42. Therefore, the housing 40 can stably support the flexible cables 20 and 30.

[0058] In the connector 10 of this embodiment 1, a first recess 51A is provided in the wall of the first cavity 50 opposite to the second cavity 60, into which the protruding end 41D of the first lance 41 fits. A second recess 61A is provided in the wall of the second cavity 60 opposite to the first cavity 50, into which the protruding end 42D of the second lance 42 fits. With this configuration, by providing the first recess 51A in the housing 40, it is not necessary to create a structure that avoids interference with the protruding end 41D of the first lance 41 (for example, a structure that increases the size of the first cavity 50), and the housing 40 can be made lower in height. Similarly, by providing the second recess 61A in the housing 40, it is not necessary to create a structure that avoids interference with the protruding end 42D of the second lance 42 (for example, a structure that increases the size of the second cavity 60), and the housing 40 can be made lower in height.

[0059] <Other Embodiments> The embodiments disclosed herein should be considered in all respects to be illustrative and not restrictive. The scope of the present invention is not limited to the embodiments disclosed herein, but is indicated by the claims, and all modifications within the meaning and scope equivalent to the claims are intended to be included.

[0060] In Embodiment 1, in the description of the assembly process of both flexible cables 20 and 30, the first flexible cable 20 was inserted into the first cavity 50, and then the second flexible cable 30 was inserted into the second cavity 60. However, the second flexible cable 30 may be inserted into the second cavity 60 first, and then the first flexible cable 20 may be inserted into the first cavity 50.

[0061] In Embodiment 1, the first locking holes 25 were provided at both ends of the first flexible cable 20 in the width direction (left-right direction), but they may also be provided at other locations, such as inside the width direction (left-right direction) of the first flexible cable 20.

[0062] In Embodiment 1, the first locking hole 25 was open to the outside in the width direction of the first flexible cable 20, but it may also be a window-shaped opening with a closed edge that does not open to the outer edge.

[0063] In Embodiment 1, the mating connector 110 is shown as a connector mounted on the circuit board 100, but it may also be a connector in which, for example, a terminal fitting with a wire is housed in a housing. [Explanation of Symbols]
