[0003] [Patent Document 1] JP 2005-44643 A [Patent Document 2] JP 2007-87681 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the configuration of Patent Document 1, since the ferrite core is not held in the through hole, there is a problem that the ferrite core is likely to slip out backward before the lid is attached to the housing. Also, even after the lid is attached, the ferrite core may rattle in the through hole.

[0005] Therefore, the present disclosure provides a technique that enables a ferrite core to be stably arranged within a housing. [Means for solving the problem]

[0006] The connector of the present disclosure comprises a ferrite core and a housing having an accommodating portion for accommodating the ferrite core, and at least one of the inner surface of the accommodating portion and the outer surface of the ferrite core has a protrusion that contacts the other and holds the ferrite core within the accommodating portion. Effect of the Invention

[0007] According to the present disclosure, the ferrite core can be stably disposed within the housing. [Brief description of the drawings]

[0009] [Description of the embodiments of the present disclosure] First, the embodiments of the present disclosure will be listed and described. The connector of the present disclosure comprises: (1) A housing having a ferrite core and an accommodating portion for accommodating the ferrite core, wherein at least one of the inner surface of the accommodating portion and the outer peripheral surface of the ferrite core has a protrusion that contacts the other to hold the ferrite core within the accommodating portion.

[0010] According to the above connector, the ferrite core can be stably disposed within the accommodating portion of the housing.

[0011] (2) It is preferable that the protrusion protrudes only from the inner surface of the housing portion out of the inner surface of the housing portion and the outer circumferential surface of the ferrite core.

[0012] Since there is no need to provide a protrusion on the ferrite core, the structure of the ferrite core can be prevented from becoming complicated.

[0013] (3) It is preferable that the housing portion has a flexible portion on the outside that is flexible and deformable, and that the flexible portion presses the ferrite core and holds it within the housing portion with the protrusion in contact with the other portion.

[0014] According to the above connector, when the ferrite core is accommodated in the accommodation portion, the flexible portion is pressed from the outer peripheral surface of the ferrite core via the protrusion and is flexible outward, thereby reducing the frictional force generated during accommodation. Moreover, the above connector can improve the holding force for holding the ferrite core by the elastic return force of the flexible portion.

[0015] (4) It is preferable that the accommodating portion has an opening through which an outer peripheral surface of the ferrite core accommodated in the accommodating portion is exposed to the outside of the housing.

[0016] According to the above connector, it is possible to check from the outside through the opening whether or not a ferrite core is placed in the housing portion.

[0017] (5) It is preferable that the inner surface of the accommodating portion has a first inner surface and a second inner surface facing each other, the ferrite core and the convex portion are arranged between the first inner surface and the second inner surface, the housing has an opening portion that opens the inside of the accommodating portion on a side other than the side where the first inner surface and the second inner surface face each other, and at least one of the first inner surface and the second inner surface and a surface of the ferrite core facing the at least one of the first inner surface and the second inner surface have portions that fit together in a concave-convex manner to restrict displacement of the ferrite core toward the opening portion.

[0018] According to the above connector, it is possible to prevent the ferrite core from being displaced toward the open portion, and it is possible to maintain the state in which the protrusion is in contact with the other portion.

The fitting grooves 81 are provided on both the upper and lower sides of the outer circumferential surface 12A of the ferrite core 12. The fitting grooves 81 extend along the front-rear direction. The fitting grooves 81 are formed over the entire area of ​​the ferrite core 12 in the front-rear direction.

[0024] <Housing 11> The housing 11 is made of synthetic resin and has insulating properties. The housing 11 has a receiving portion 20, a first protrusion 21, and a fitting protrusion 22, as shown in FIG.

[0025] The internal space of the accommodating section 20 is open to the rear as shown in FIG. 4. The ferrite core 12 is accommodated in the accommodating section 20 from the rear.

A plurality of first convex portions 21 are provided at intervals in the left-right direction. The first convex portion 21 is disposed on the back surface 24 side of the accommodating portion 20. The first convex portion 21 extends along the front-rear direction. The front end of the first convex portion 21 is continuous with the back surface 24. The width dimension of the first convex portion 21 in the left-right direction is smaller than the width dimension of the first inner surface 25 in the left-right direction. The first convex portion 21 has a first front convex portion 21A and a first rear convex portion 21B. The first front convex portion 21A is curved downward so that the center in the left-right direction protrudes. The front end of the first front convex portion 21A is continuous with the back surface 24. The protruding dimension of the first front convex portion 21A is constant in the front-rear direction. The front end of the first rear convex portion 21B is continuous with the rear end of the first front convex portion 21A. The protruding dimension of the first rear convex portion 21B decreases toward the rear. The first convex portion 21 is provided to the left of the second hole portion 30 at the left end and also to the right of the second hole portion 30 at the right end. When the maximum dimension in the vertical direction of the outer peripheral surface 12A of the ferrite core 12 is X1, the vertical interval between the first inner surface 25 and the second inner surface 26 is X2, and the maximum protruding dimension of the first convex portion 21 (in other words, the protruding dimension of the first front convex portion 21A) is X3, the relationship X2 - X3 < X1 holds.

[0027] The fitting convex portion 22 is provided on the second inner surface 26. The fitting convex portion 22 extends along the front-rear direction. The fitting convex portion 22 protrudes at the center in the left-right direction and is curved upward. The protruding dimension of the fitting convex portion 22 is constant in the front-rear direction. The fitting convex portion 22 is disposed between the two first convex portions 21 in the left-right direction and between the two second hole portions 30.

[0028] As shown in FIG. 4 and FIG. 5, the storage section 20 has a first flexible portion 28. The first flexible portion 28 corresponds to a "flexible portion". The first flexible portion 28 has a shape supported at both front and rear ends, and is capable of being flexibly deformed outward. The front end of the first flexible portion 28 is connected to and supported by a wall portion constituting the rear surface 24 of the storage section 20. The rear end of the first flexible portion 28 is connected to and supported by a lower end of a bridge portion 40 described later. A plurality of first flexible portions 28 (two in this embodiment) are provided at intervals in the left-right direction. The inner surface of the first flexible portion 28 constitutes a part of the inner surface 23 of the storage section 20. A first protrusion 21 is provided on each inner surface of the plurality of first flexible portions 28. The front end of the first protrusion 21 is aligned with the front end of the first flexible portion 28 in the front-rear direction. The rear end of the first protrusion 21 is aligned in the front-rear direction with the rear end of the first flexible portion 28. Note that the rear end of the first protrusion 21 may be disposed forward of the rear end of the first flexible portion 28.

[0029] 5 and 10, the accommodation portion 20 has a first opening 29. The first opening 29 corresponds to an "opening". The first opening 29 exposes the outer peripheral surface 12A of the ferrite core 12 accommodated in the accommodation portion 20 to the outside of the housing 11. The first opening 29 is provided between two first flexible portions 28.

[0030] As shown in FIGS. 7 and 8, the housing 11 has a second hole portion 30, a second protrusion portion 31, a second flexible portion 32, a second opening portion 33, a front wall 34, and an insertion hole 35.

[0031] As shown in FIG. 7, the second hole 30 communicates with the internal space of the accommodating portion 20 and extends forward from the internal space of the accommodating portion 20. The second hole 30 is disposed in front of the first hole 80 of the ferrite core 12 accommodated in the accommodating portion 20. The second hole 30, together with the first hole 80, constitutes a cavity extending along the front-rear direction. The vertical dimension of the inner peripheral surface 30A of the second hole 30 is the same as the vertical dimension of the inner peripheral surface of the first hole 80, and the left-right dimension of the inner peripheral surface 30A of the second hole 30 is the same as the left-right dimension of the inner peripheral surface of the first hole 80. The terminal metal fitting 13 inserted from the rear of the first hole 80 is inserted up to the second hole 30. A front wall 34 is provided on the front side of the second hole 30. The front wall 34 restricts the forward movement of the terminal metal fitting 13 arranged in the second hole 30. The insertion hole 35 penetrates the front wall 34 in the front-rear direction. The second hole portion 30 communicates with the insertion hole 35. A mating terminal fitting 92 of a mating connector 90 inserted from the outside through the insertion hole 35 is electrically connected to the terminal fitting 13 arranged in the second hole portion 30 (see FIG. 14). The inner peripheral surface 30A of the second hole portion 30 has a first surface 37 and a second surface 38. The first surface 37 is provided on the upper side and faces downward. The second surface 38 is provided on the lower side and faces upward. The first surface 37 and the second surface 38 face each other.

[0032] As shown in FIGS. 7 and 8, the second convex portion 31 protrudes from the first surface 37 of the second hole portion 30. The second convex portion 31 is disposed on the front end side of the second hole portion 30. The second convex portion 31 extends along the front-rear direction. The front end of the second convex portion 31 is continuous with the rear end of the front wall 34. The width dimension of the second convex portion 31 in the left-right direction is smaller than the width dimension of the first surface 37 in the left-right direction. The second convex portion 31 has a second front convex portion 31A and a second rear convex portion 31B. The second front convex portion 31A is curved downward so that the center in the left-right direction protrudes. The front end of the second front convex portion 31A is continuous with the rear end of the front wall 34. The protruding dimension of the second front convex portion 31A is constant in the front-rear direction. The front end of the second rear convex portion 31B is continuous with the rear end of the second front convex portion 31A. The protruding dimension of the second rear convex portion 31B becomes smaller toward the rear. When the maximum dimension in the vertical direction of the cylindrical portion 70 in the terminal fitting 13 is Y1, the vertical interval between the first surface 37 and the second surface 38 is Y2, and the maximum protruding dimension of the second convex portion 31 (in other words, the protruding dimension of the second front convex portion 31A) is Y3, the relationship of Y2 - Y3 < Y1 holds.

[0033] As shown in FIGS. 7, 8, and 10, the second bending portion 32 has a both-end-supported shape with both front and rear ends supported, and can be bent and deformed outward. The front end portion of the second bending portion 32 is supported by the front wall 34, and the rear end portion of the second bending portion 32 is supported by the wall portion constituting the inner surface 24 of the housing portion 20. The inner surface of the second bending portion 32 constitutes a part of the inner peripheral surface 30A of the second hole portion 30. The second convex portion 31 is provided on the inner surface of the second bending portion 32. The front end of the second convex portion 31 is aligned with the front end of the second bending portion 32 in the front-rear direction. The rear end of the second convex portion 31 is disposed in front of the rear end of the second bending portion 32. Note that the rear end of the second convex portion 31 may be aligned with the rear end of the second bending portion 32 in the front-rear direction.

[0034] As shown in FIGS. 8 and 10, the second opening 33 exposes the cylindrical portion 70 disposed in the second hole portion 30 to the outside of the housing 11. The second opening 33 exposes the front end of the cylindrical portion 70 to the outside of the housing 11. The second opening 33 is provided on both the left and right sides of the second bending portion 32.

[0035] As shown in FIG. 12, the housing 11 has a bridge portion 40, a restricting portion 41, and a guiding portion 42. The bridge portion 40 connects the left and right sides of the upper end of the storage portion 20 to each other. The bridge portion 40 has legs 40A extending upward from the left and right sides of the storage portion 20, connecting portions 40B connecting the left and right legs 40A to each other, and extending portions 40C extending outward in the left and right direction from the left and right legs 40A. The restricting portion 41 is provided below the connecting portions 40B. The restricting portion 41 restricts the forward movement of the detection member 15. The guiding portion 42 is provided below the restricting portion 41. The guiding portion 42 guides a pair of lock arms 62 (described later) of the detection member 15 to spread outward in the left and right direction.

[0036] As shown in Figs. 12 and 13, the housing 11 has a first elastic locking portion 43. The first elastic locking portion 43 is provided in pairs at the ends of both the left and right sides of the housing 11. The first elastic locking portion 43 is connected to the lower surface of the extension portion 40C on both the left and right sides of the bridge portion 40, and each extends forward in a cantilever shape. The first elastic locking portion 43 covers both the left and right sides of the storage portion 20. The first elastic locking portion 43 has a first elastic plate portion 43A, a first temporary locking portion 43B, and a first full locking portion 43C. The first elastic plate portion 43A extends forward from the bridge portion 40 in a cantilever shape and has a plate shape having a thickness in the left and right direction. The first temporary locking portion 43B and the first full locking portion 43C are provided on the inside in the left and right direction of the first elastic plate portion 43A. The first provisional locking portion 43B is disposed rearward of the first full locking portion 43C. The first elastic locking portion 43 locks the detection member 15.

[0037] 2, the housing 11 has a hanging portion 44. The hanging portion 44 hangs down from the rear end of the storage portion 20. The hanging portion 44 is wall-shaped and has a thickness in the front-rear direction. The hanging portion 44 has a cover locking portion 44A.

[0038] <Cover member 14> As shown in FIG. 2, the cover member 14 has a cover body 50, a first through hole 51, a second through hole 52, and a cover side locking portion 53. The cover body 50 is wall-shaped with a thickness in the front-rear direction. The first through hole 51 penetrates the cover body 50 in the front-rear direction. The first through hole 51 is provided in pairs on both the left and right sides of the cover body 50. The second through hole 52 penetrates the cover body 50 in the front-rear direction. The second through hole 52 is provided in pairs on both the left and right sides of the cover body 50. The pair of second through holes 52 is disposed on the inside in the left-right direction of the first through holes 51 on both the left and right sides. The cover side locking portion 53 is flexible and is locked to the cover locking portion 44A of the housing 11.

[0039] <Detection member 15> As shown in FIG. 2, the detection member 15 has a base portion 60, a second elastic locking portion 61, a lock arm 62, and an interference portion 63. The base portion 60 is plate-shaped with a thickness in the front-rear direction. The second elastic locking portion 61 extends forward from the base portion 60 in a cantilever shape. The second elastic locking portion 61 is provided in pairs on the left and right. As shown in FIG. 2 and FIG. 13, the second elastic locking portion 61 has a second elastic plate portion 61A, a second temporary locking portion 61B, and a second full locking portion 61C. The second elastic plate portion 61A extends forward from the base portion 60 in a cantilever shape and is plate-shaped with a thickness in the left-right direction. The second temporary locking portion 61B and the second full locking portion 61C are provided on the outside of the second elastic plate portion 61A in the left-right direction. The second temporary locking portion 61B is disposed rearward of the second full locking portion 61C. The second temporary locking portion 61B is locked to the first temporary locking portion 43B of the housing 11. This allows the detection member 15 to be temporarily locked to the housing 11. The second full locking portion 61C is locked to the first full locking portion 43C of the housing 11. This allows the detection member 15 to be fully locked to the housing 11.

[0040] <Mating connector 90> As shown in Figs. 14 to 16, the mating connector 90 has a mating housing 91, a mating terminal fitting 92, and a short-circuit terminal 93. The mating housing 91 has an outer housing 94 and an inner housing 95. The inner housing 95 has a lock receiving portion 96. A plurality of mating terminal fittings 92 (two in this embodiment) are provided. Before the mating connector 90 is fitted into the connector 10, the short-circuit terminal 93 is electrically connected to each of the two mating terminal fittings 92.

[0041] <Assembly of connector 10> As shown in FIG. 4, the ferrite core 12 is accommodated in the accommodation portion 20 of the housing 11 from the rear. In the early stage of accommodation, the ferrite core 12 does not interfere with the first convex portion 21 in the accommodation portion 20, so that the frictional resistance applied to the ferrite core 12 is small and the ferrite core 12 is smoothly inserted. When the ferrite core 12 interferes with the first rear convex portion 21B, the frictional resistance applied to the ferrite core 12 gradually increases as the ferrite core 12 moves forward. At this time, the ferrite core 12 moves forward while bending the first bending portion 28 outward. When the ferrite core 12 moves further forward, it interferes with the first front convex portion 21A, and the flat upper surface of the outer circumferential surface 12A of the ferrite core 12 strongly contacts the first front convex portion 21A. Since the front end of the first bending portion 28 is fixed, the frictional resistance applied to the ferrite core 12 increases further as the ferrite core 12 moves forward. When the ferrite core 12 moves to the regular accommodation position, it is sandwiched between the first protrusion 21 and the second inner surface 26 as shown in Fig. 6, and is held in a state in which rattling of the ferrite core 12 is restricted. As a result, the ferrite core 12 is accommodated in the accommodation portion 20. The ferrite core 12 accommodated in the accommodation portion 20 is exposed to the outside of the housing 11 through the first opening 29 as shown in Fig. 10.

[0042] 11, when the ferrite core 12 is accommodated in the accommodation portion 20, the fitting groove 81 on the lower side of the ferrite core 12 is accommodated so as to fit into the fitting protrusion 22 of the accommodation portion 20. This prevents the ferrite core 12 from being displaced in the left-right direction.

[0043] 7, the tubular portion 70 of the terminal fitting 13 is inserted from the rear into the first hole 80 of the ferrite core 12 held in the housing portion 20. The second protrusion 31 is not provided in the first hole 80. Therefore, until the front end of the tubular portion 70 passes through the first hole 80, frictional resistance acting on the tubular portion 70 is small, and the tubular portion 70 is smoothly inserted.

[0044] After passing through the first hole 80, the front end of the tube portion 70 is inserted into the second hole 30 disposed in front of the first hole 80, as shown in FIG. 9. The vertical and horizontal dimensions of the second hole 30 are the same as those of the first hole 80, so that if the position of the ferrite core 12 is not determined, the tube portion 70 may strike the peripheral portion of the rear end of the second hole 30. In this regard, since the ferrite core 12 is held between the first protrusion 21 and the second inner surface 26 in the connector 10, the first hole 80 and the second hole 30 are easily aligned in the front-rear direction. Therefore, the tube portion 70 is unlikely to strike the peripheral portion of the rear end of the second hole 30, and is easily inserted into the second hole 30 smoothly. When the tube portion 70 is inserted into the second hole 30, the tube portion 70 interferes with the second rear protrusion 31B halfway through. When the tube portion 70 interferes with the second rear convex portion 31B, the frictional resistance applied to the tube portion 70 gradually increases as the tube portion 70 moves forward. At this time, the tube portion 70 moves forward while bending the second flexible portion 32 outward. When the tube portion 70 moves further forward, it interferes with the second front convex portion 31A, and the flat upper surface of the outer circumferential surface 70A of the tube portion 70 strongly contacts the second front convex portion 31A. Since the front end of the second flexible portion 32 is fixed, the frictional resistance applied to the tube portion 70 increases further as the tube portion 70 moves forward. When the tube portion 70 moves to the normal insertion position, it is sandwiched between the second convex portion 31 and the second surface 38, and is held in a state in which rattling is restricted. As a result, the tube portion 70 is arranged from inside the first hole portion 80 to inside the second hole portion 30. The cylindrical portion 70 disposed in the second hole portion 30 is exposed to the outside of the housing 11 through the second opening portion 33, as shown in FIG.

[0045] 12, the cover member 14 is attached to the housing 11 to cover the rear of the terminal fitting 13. Then, as shown in FIG. 13, the detection member 15 is provisionally locked to the housing 11. When provisionally locked, the pair of second elastic locking portions 61 of the detection member 15 are inserted into the pair of first through holes 51 of the cover member 14, respectively. The pair of lock arms 62 of the detection member 15 are inserted into the pair of second through holes 52 of the cover member 14, respectively. The pair of second elastic locking portions 61 are disposed between the accommodating portion 20 of the housing 11 and the pair of first elastic locking portions 43. Then, as shown in FIG. 17, after the connector 10 is fitted into the mating connector 90, the detection member 15 is fully locked to the housing 11. At this time, the lock arms 62 of the detection member 15 are locked to the lock receiving portions 96 of the mating connector 90, as shown in FIG. 15. 14, the lock arm 62 releases the electrical connection between the mating terminal fitting 92 and the shorting terminal 93. The pair of second elastic locking portions 61 fills the gap formed between the ferrite core 12 disposed in the accommodating portion 20 and the pair of first elastic locking portions 43, as shown in FIG.

[0046] If the detection member 15 is moved from the provisional locking position to the full locking position when the connector 10 is not properly mated with the mating connector 90, the pair of lock arms 62 are spread apart in the left-right direction by the guide portions 42, and then closed without being maintained in that state by the lock receiving portions 96 (see FIGS. 16 and 17). As a result, the restricting portions 41 interfere with the interference portions 63, and the forward movement of the detection member 15 is restricted. In other words, by the fact that the detection member 15 is locked with the mating connector 90, it can be confirmed that the connector 10 is properly mated with the mating connector 90.

[0047] <Effects of Connector 10> According to the connector 10, the ferrite core 12 arranged in the accommodating portion 20 of the housing 11 is held in a state sandwiched between the first protrusion 21 and the second inner surface 26. This positions the ferrite core 12, making it easier to insert the terminal fitting 13 into the first hole 80 of the ferrite core 12 and also easier to insert into the second hole 30 arranged in front of the first hole 80. Moreover, since the first protrusion 21 is provided only on the upper side within the accommodating portion 20, the position in the vertical direction is more stable than in a configuration in which the first protrusion 21 is provided on both the upper and lower sides.

[0048] Furthermore, since the first convex portion 21 is positioned on the rear surface 24 side of the accommodating portion 20, the ferrite core 12 can interfere with the first convex portion 21 only at the end of the insertion, and as a result, the frictional force at the beginning of the insertion can be reduced.

[0049] Furthermore, the first protrusion 21 protrudes from the inner side surface of the first flexible portion 28. Therefore, when the ferrite core 12 is accommodated in the accommodation portion 20, the first flexible portion 28 is pressed by the outer peripheral surface 12A of the ferrite core 12 via the first protrusion 21 and bends outward, thereby reducing the frictional force generated during accommodation. Moreover, the connector 10 can improve the holding force for holding the ferrite core 12 by the elastic restoring force of the first flexible portion 28.

[0050] Furthermore, the outer peripheral surface 12A of the ferrite core 12 accommodated in the accommodation portion 20 is exposed to the outside of the housing 11 through the first opening 29. Therefore, it is possible to visually check from the outside through the first opening 29 whether the ferrite core 12 is arranged in the accommodation portion 20 or not.

[0051] Furthermore, an engagement groove 81 is provided on the outer peripheral surface 12A of the ferrite core 12, and an engagement protrusion 22 is provided on the second inner side surface 26 of the accommodating section 20. Therefore, by engaging the engagement protrusion 22 with the engagement groove 81, it is possible to suppress positional deviation of the ferrite core 12 in the left-right direction (opening section 27), and it is possible to maintain a state in which the first protrusion 21 and the outer peripheral surface 12A of the ferrite core 12 are in contact with each other.

[0052] Furthermore, since the cylindrical portion 70 of the terminal fitting 13 is held within the second hole portion 30, the terminal fitting 13 disposed within the first hole portion 80 penetrating the ferrite core 12 can be held. This also determines the position of the terminal fitting 13, facilitating connection with the mating terminal fitting 92. Moreover, since the second protrusion 31 is provided only on the upper side of the second hole portion 30, the position in the vertical direction is more stable than in a configuration in which the second protrusion 31 is provided on both the upper and lower sides.

[0053] Furthermore, the second protrusion 31 protrudes only from the inner peripheral surface 30A of the second hole 30, out of the inner peripheral surface 30A of the second hole 30 and the outer peripheral surface 70A of the tube portion 70. If the second protrusion 31 protrudes from the outer peripheral surface 70A of the tube portion 70, there is a risk that the second protrusion 31 will scrape the inner peripheral surface of the ferrite core 12 when the terminal fitting 13 is inserted into the first hole 80. However, according to the connector 10, since the second protrusion 31 is provided only on the housing 11 side, such a problem can be avoided. Furthermore, since interference between the terminal fitting 13 and the second protrusion 31 does not occur in the first hole 80, the frictional force applied to the terminal fitting 13 when the terminal fitting 13 is inserted into the first hole 80 can be reduced.

[0054] Furthermore, the second protrusion 31 protrudes from the second flexible portion 32. Therefore, when the terminal fitting 13 is inserted into the second hole 30, the second flexible portion 32 is pressed by the cylindrical portion 70 via the second protrusion 31 and is flexible outward, thereby reducing the frictional force generated during insertion. Moreover, the connector 10 can improve the holding force for holding the terminal fitting 13 by the elastic force of the second flexible portion 32.

[0055] Furthermore, the tubular portion 70 is exposed to the outside of the housing 11 through the second opening 33. Therefore, it is possible to visually check from the outside through the second opening 33 whether the tubular portion 70 is disposed in the second hole portion 30 or not.
