[0009] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. The terminal fitting of the present disclosure is (1) A terminal fitting including a cylindrical portion and a plurality of elastic contact pieces extending in a cantilever shape from the cylindrical portion, The cylindrical portion is formed by bending a plate material so that a seam is exposed on the outer circumferential surface, The cylindrical portion has two adjacent portions sandwiching the seam, One of the portions is provided with an opening prevention portion that abuts against or faces closely to an outer surface of the other portion. According to the configuration of the present disclosure, the opening prevention portion provided on one portion of the cylindrical portion abuts against or faces closely to the outer surface of the other portion adjacent to the one portion across the seam. Therefore, the other portion of the cylindrical portion comes into contact with the opening prevention portion, thereby suppressing the radial outward displacement of the other portion. Therefore, opening from the seam of the cylindrical portion can be suppressed. (2) In the terminal fitting to be assembled to the housing, it is preferable that the opening prevention portion is bent when viewed in the axial direction of the cylindrical portion. According to this configuration, the rigidity of the opening prevention part can be increased. Therefore, when the opening prevention part with high rigidity comes into contact with the other part of the cylindrical part, the radially outward displacement of the other part is further suppressed. Therefore, opening from the joint of the cylindrical part can be further suppressed. (3) It is preferable that the opening prevention portion is inserted into a groove provided in the housing when the terminal fitting is attached to the housing. This configuration makes it possible to prevent the terminal fitting from rotating relative to the housing. (4) It is preferable that the opening prevention portion has an inclined portion that is inclined with respect to the outer surface of the other portion. With this configuration, the position at which the opening prevention portion contacts the outer surface of the other portion is more easily determined than in a configuration in which the opening prevention portion contacts the outer surface of the other portion along a surface parallel to the outer surface of the other portion, thereby reducing variation in the shape of the terminal fitting. (5) It is preferable that the opening prevention portion is provided with a protrusion that bites into the outer surface of the other portion. With this configuration, the anti-opening portion and the other portion are less likely to become misaligned, and radial outward displacement of the other portion is further suppressed, thereby further preventing opening from occurring at the joint of the cylindrical portion. (6) It is preferable that the opening prevention portion rises in the axial direction of the cylindrical portion to a position near the tip of the mating terminal that contacts the resilient contact piece. According to this configuration, the impedance around the cylindrical portion can be changed by the opening prevention portion, and therefore it is possible to match the impedance between the portion of the terminal fitting adjacent to the mating terminal and the portion of the terminal fitting not adjacent to the mating terminal. (7) In the terminal fitting assembled to the housing, it is preferable that a protrusion to be press-fitted into the housing is provided on an outer surface of one of the portions of the cylindrical portion or on an outer surface in the vicinity of the one of the portions. According to this configuration, by press-fitting the protrusion into the housing, one portion of the cylindrical portion is less likely to move radially outward. This makes it easier to maintain the contact state of the opening prevention portion with the other portion, and further suppresses the radially outward displacement of the other portion. This further suppresses opening from the joint of the cylindrical portion.

[0010] [Details of the embodiment of the present disclosure] [Example 1] A first embodiment of a terminal fitting according to the present disclosure will be described with reference to Figs. 1 to 12. In this first embodiment, the up-down direction is defined as the upward direction and the downward direction as they appear in Figs. 1 to 4, 6, 7, 9, 11, and 12. The front-rear direction is defined as the left-hand direction and the right-hand direction as they appear in Fig. 4. The left-hand direction and the right-hand direction are defined as the left-hand direction and the right-hand direction as they appear in Figs. 2, 5, 8, and 10.

[0011] (Terminal metal fitting configuration) The terminal fitting 10 of the present embodiment 1 is a female terminal fitting, as shown in FIG. 1 . The terminal fitting 10 is a single part made of a metal material. The terminal fitting 10 is formed by pressing or bending a conductive metal plate. The terminal fitting 10 has an elongated cylindrical shape as a whole. The terminal fitting 10 includes a cylindrical portion 20, a connection portion 30, and a mounting portion 40.

[0012] As shown in Fig. 1, the cylindrical portion 20 constitutes the axial center portion of the terminal fitting 10. The cylindrical portion 20 is formed by bending a plate material in the circumferential direction. As shown in Fig. 6, a first seam 21 and a second seam 22 are exposed on the outer circumferential surface of the cylindrical portion 20. The first seam 21 is parallel to the axial direction. The second seam 22 is along the circumferential direction. The second seam 22 corresponds to the "seam" in this disclosure.

[0013] The connection part 30 is a part that is connected to a mating terminal 60 (see FIG. 4). As shown in FIG. 1, the connection part 30 has a pair of elastic contact pieces 31 and a pair of slide pieces 32, 33. The pair of elastic contact pieces 31 and the pair of slide pieces 32, 33 extend in a cantilever shape from the cylindrical part 20. The pair of elastic contact pieces 31 and the pair of slide pieces 32, 33 are arranged side by side with a gap in the circumferential direction. The pair of elastic contact pieces 31 are arranged facing each other across the axis L (see FIG. 5). As shown in FIG. 7, the elastic contact piece 31 once extends obliquely inward from the upper end of the cylindrical part 20 and then extends obliquely outward. The slide pieces 32, 33 guide the insertion of the mating terminal 60 (see FIG. 4) into the connection part 30. The slide pieces 32, 33 are arranged facing each other across the axis L (see FIG. 5). As shown in Figures 1 to 3, the slide pieces 32 and 33 are rectangular plate-shaped. Both corners of the tip of the slide piece 32 are angular. Both corners of the tip of the slide piece 33 are rounded.

[0014] The mounting portion 40 is connected to, for example, a printed circuit (not shown) of a circuit board. As shown in Fig. 1, the mounting portion 40 has a tapered portion 41, a peripheral wall portion 42, and a leg portion 43. The tapered portion 41 is shaped like a truncated cone connecting the lower end of the cylindrical portion 20 and the upper end of the peripheral wall portion 42. The peripheral wall portion 42 is cylindrical. The leg portion 43 protrudes downward from the lower end of the peripheral wall portion 42. The leg portion 43 is in the shape of a plate bent into an L shape.

[0015] As shown in FIG. 6, the cylindrical portion 20 has a main body portion 23, a first portion 24, and a second portion 25. The first portion 24 corresponds to "one portion" in the present disclosure. The second portion 25 corresponds to "the other portion" in the present disclosure. The main body portion 23 is arc-shaped when viewed from the axial direction. The axial width of the main body portion 23 is constant in the circumferential direction. The first portion 24 is plate-shaped and extends in the circumferential direction from one circumferential end of the main body portion 23. The axial width of the first portion 24 is smaller than the axial width of the main body portion 23. The first portion 24 is arc-shaped when viewed from the axial direction. A first edge portion 23A extending in the axial direction is provided at an upper end portion (a portion where the first portion 24 is not provided) of one circumferential end of the main body portion 23.

[0016] As shown in Fig. 6, the second portion 25 is plate-shaped and extends circumferentially from the other circumferential end of the main body 23. The axial width of the second portion 25 is smaller than the axial width of the main body 23. The second portion 25 is arc-shaped when viewed in the axial direction. A second edge portion 23B (see Figs. 3 and 4) extending in the axial direction is provided at a lower end portion (a portion where the second portion 25 is not provided) of the other circumferential end of the main body 23.

[0017] As shown in Figures 3, 4, and 6, a pair of arc-shaped slits S1 and S2 are provided between the cylindrical portion 20 and the tapered portion 41 of the mounting portion 40 in the circumferential direction. The slit S1 extends toward the main body portion 23 from the base end of the first portion 24. The slit S2 has a length approximately equal to that of the slit S1 and extends in the opposite direction to the slit S1.

[0018] As shown in Fig. 6, the first portion 24 and the second portion 25 are adjacent to each other with the second seam 22 in between. The first portion 24 and the second portion 25 overlap in the up-down direction. An upper end 24A of the first portion 24 and a lower end 25A of the second portion 25 in the axial direction are in contact with each other to form the second seam 22.

[0019] 6, the tip 25B of the second portion 25 and the first edge portion 23A are in contact with each other to form the first seam 21. The tip 25B of the second portion 25 is in contact with the first edge portion 23A in the circumferential direction. A crimped portion 26 is provided between the tip 25B of the second portion 25 and the first edge portion 23A. The crimped portion 26 is formed by welding the tip 25B of the second portion 25 to the first edge portion 23A.

[0020] 8, a gap 27 is provided between a tip 24B (an end in the extending direction) of the first portion 24 and a second edge portion 23B of the main body portion 23. The gap 27 is in the form of a slit that is long in the axial direction.

[0021] As shown in FIG. 6, the first portion 24 is provided with an opening prevention portion 50. The opening prevention portion 50 prevents the cylindrical portion 20 from opening from the second joint 22. The opening prevention portion 50 rises outward in the radial direction from the tip 24B (see FIG. 8) of the first portion 24. The axial width of the opening prevention portion 50 is wider than the axial width of the first portion 24. The opening prevention portion 50 is formed by folding a plate portion that is wider (wider in the axial direction) than the first portion 24. The opening prevention portion 50 is bent in a U-shape when viewed from the axial direction so as to be convex radially outward. Therefore, the rigidity of the opening prevention portion 50 can be increased.

[0022] As shown in FIG. 6, the opening prevention part 50 has a first plate part 51, a second plate part 52, and a bent part 53. The opening prevention part 50 is connected to the first part 24 in the order of the first plate part 51, the bent part 53, and the second plate part 52. The first plate part 51 is a rectangular plate. The second plate part 52 is a trapezoidal plate having an inclined part 54 (see FIG. 7) at a tip (end part opposite to the bent part 53). As shown in FIG. 7, the inclined part 54 is inclined with respect to the outer surface (axial direction) of the second part 25. The inclined part 54 is inclined downward toward the radial inside of the second part 25. One plate surface of the first plate part 51 and one plate surface of the second plate part 52 face each other in the circumferential direction. The bent part 53 is bent so as to be convex toward the radial outside.

[0023] As shown in FIG. 6, the opening prevention portion 50 is provided with a protruding portion 55 that protrudes upward (toward the connection portion 30) from the first portion 24. The protruding portion 55 constitutes an upper end portion of the opening prevention portion 50. The protruding portion 55 faces the outer surface of the second portion 25. As shown in FIG. 4, the protruding portion 55 rises in the axial direction to a position near the tip of the mating terminal 60 that contacts the elastic contact piece 31 (a position slightly below the tip of the mating terminal 60). This allows the opening prevention portion 50 to change the impedance around the cylindrical portion 20. Therefore, it is possible to match the impedance between the portion of the terminal fitting 10 adjacent to the mating terminal 60 and the other portions.

[0024] The opening prevention portion 50 abuts against the outer surface of the second portion 25, as shown in Figs. 2 and 7. As shown in Figs. 7 and 8, the lower end side of the inclined portion 54 of the second plate portion 52 enters the gap 27 from the outside. The inclined portion 54 abuts against the outer surface of the lower edge of the second portion 25, as shown in Figs. 3 and 7. The second portion 25 of the cylindrical portion 20 comes into contact with the opening prevention portion 50, thereby suppressing the radially outward displacement of the second portion 25. Therefore, the opening of the cylindrical portion 20 from the second joint 22 can be suppressed. In particular, since the rigidity of the opening prevention portion 50 is increased by the bent shape, the opening of the cylindrical portion 20 from the second joint 22 can be further suppressed.

[0025] The impedance of the terminal fitting 10 can be adjusted by changing the radial outward protrusion width, axial width, and other dimensions of the opening prevention portion 50.

[0026] The inclined portion 54 is in contact with the outer surface of the second portion 25 in an inclined state. Therefore, the position where the opening prevention portion 50 contacts the outer surface of the second portion 25 is more easily determined than in a configuration in which the opening prevention portion 50 contacts the outer surface of the second portion 25 on a surface parallel to the outer surface of the second portion 25. This makes it possible to reduce variation in the shape of the terminal fitting 10.

[0027] As shown in Figs. 5 and 6, four protrusions 28 are provided on the outer surface of the cylindrical portion 20. The protrusions 28 are press-fitted into a housing 70, which will be described later. The protrusions 28 are arranged at equal intervals along the outer periphery of the cylindrical portion 20. The protrusions 28 protrude in the outer shape direction. The protrusions 28 are formed by hammering, for example. One of the protrusions 28 is provided near the center of the outer surface of the first portion 24.

[0028] (Assembling the terminal fittings) A conductive metal plate is pressed, bent, or otherwise processed to be formed into a long, thin tube shape as shown in Figs. 9 and 10. Specifically, the first edge 23A of the main body 23 and the tip 25B of the second portion 25 are joined to form the first seam 21. Next, the first seam 21 is welded to form the crimped portion 26. Here, the upper end 24A of the first portion 24 is located radially outward relative to the lower end 25A of the second portion 25, and the second seam 22 is not formed. As shown in Fig. 10, the inclined portion 54 of the second plate portion 52 does not enter the gap 27 (see Fig. 8).

[0029] From the state shown in Figs. 9 and 10, the first portion 24 is bent inward (toward the axis L) to form the cylindrical portion 20. Specifically, the upper end 24A of the first portion 24 is opposed to the lower end 25A of the second portion 25 to form the second seam 22 as shown in Fig. 6. As the second seam 22 is formed, the opening prevention portion 50 is brought into contact with the outer surface of the second portion 25. Specifically, the lower end portion of the inclined portion 54 of the second plate portion 52 is inserted into the gap 27 (see Fig. 8) from the outside. As a result, the inclined portion 54 comes into contact with the outer surface of the lower edge of the second portion 25.

[0030] (Assembly structure of terminal furniture to housing) The terminal fitting 10 is assembled to the housing 70 as shown in Figs. 11 and 12. The housing 70 has a cylindrical shape. The housing 70 is made of, for example, synthetic resin. As shown in Fig. 12, the mounting portion 40 and the cylindrical portion 20 are inserted into a central hole 71 of the housing 70. As shown in Figs. 8, 11 and 12, the opening prevention portion 50 is inserted into a groove portion 72 (a groove connected to the central hole 71) of the housing 70. This makes it possible to prevent the terminal fitting 10 from rotating relative to the housing 70. As shown in Figs. 11 and 12, the connection portion 30 (a pair of elastic contact pieces 31 and a pair of slide pieces 32, 33) protrudes upward from the upper surface of the housing 70.

[0031] The opening prevention portion 50 is a portion that is pressed by the jig 80 when the terminal fitting 10 is assembled to the housing 70. After the lower end side of the opening prevention portion 50 is inserted into the groove portion 72, the upper end of the opening prevention portion 50 is pressed downward by the jig 80, whereby the opening prevention portion 50 is inserted into the groove portion 72 from above.

[0032] By press-fitting the protrusion 28 into the housing 70, the first portion 24 of the cylindrical portion 20 is less likely to move radially outward. This makes it easier to maintain the contact state of the opening prevention portion 50 with the second portion 25, and further suppresses the radially outward displacement of the second portion 25. This further suppresses the opening of the cylindrical portion 20 from the second seam 22.

[0033] (Effects of this embodiment) As described above, according to the terminal fitting 10 of the present disclosure, the first portion 24 is provided with the opening prevention portion 50 that abuts against the outer surface of the second portion 25. As a result, the opening prevention portion 50 provided in the first portion 24 of the cylindrical portion 20 abuts against the outer surface of the second portion 25 adjacent to the first portion 24 across the second seam 22. Therefore, the second portion 25 of the cylindrical portion 20 comes into contact with the opening prevention portion 50, thereby suppressing the radially outward displacement of the second portion 25. Therefore, the opening of the cylindrical portion 20 from the second seam 22 can be suppressed.

[0034] The terminal fitting 10 of the present disclosure is assembled to a housing 70. The opening prevention portion 50 is bent when viewed from the axial direction of the cylindrical portion 20. This increases the rigidity of the opening prevention portion 50. Therefore, the highly rigid opening prevention portion 50 comes into contact with the second portion 25 of the cylindrical portion 20, thereby further suppressing the radially outward displacement of the second portion 25. This further suppresses the opening of the cylindrical portion 20 from the second joint 22.

[0035] According to the terminal fitting 10 of the present disclosure, the opening prevention portion 50 is inserted into the groove portion 72 provided in the housing 70 when the terminal fitting 10 is assembled to the housing 70. This makes it possible to prevent the terminal fitting 10 from rotating relative to the housing 70.

[0036] According to the terminal fitting 10 of the present disclosure, the opening prevention portion 50 has an inclined portion 54 that is inclined with respect to the outer surface of the second portion 25. This makes it easier to determine the position where the opening prevention portion 50 contacts the outer surface of the second portion 25, compared to a configuration in which the opening prevention portion 50 makes surface contact with a surface parallel to the outer surface of the second portion 25. This makes it possible to reduce variation in the shape of the terminal fitting 10.

[0037] According to the terminal fitting 10 of the present disclosure, the opening prevention portion 50 rises in the axial direction of the cylindrical portion 20 to a position near the tip of the mating terminal 60 that contacts the elastic contact piece 31. This makes it possible for the opening prevention portion 50 to change the impedance around the cylindrical portion 20. Therefore, it is possible to match the impedance between the portion of the terminal fitting 10 where the mating terminal 60 is adjacent and the portion where the mating terminal 60 is not adjacent.

[0038] According to the terminal fitting 10 of the present disclosure, the terminal fitting 10 is assembled to the housing 70, and the protrusion 28 is provided on the outer surface of the first portion 24 of the cylindrical portion 20, which is press-fitted into the housing 70. With this, the protrusion 28 is press-fitted into the housing 70, making it difficult for the first portion 24 of the cylindrical portion 20 to move radially outward. This makes it easier to maintain the contact state of the opening prevention portion 50 with the second portion 25, and further suppresses the displacement of the second portion 25 radially outward. This further suppresses opening of the cylindrical portion 20 from the second seam 22.

[0039] [Other Examples] The present invention is not limited to the embodiments described above and shown in the drawings, but is indicated by the claims. The present invention includes the equivalent meaning of the claims and all modifications within the scope of the claims, and is intended to include the following embodiments. In the above-described first embodiment, as shown in Fig. 13, the opening prevention portion 50 may be provided with a protrusion 56 that bites into the outer surface of the second portion 25. This makes it difficult for the opening prevention portion 50 and the second portion 25 to become misaligned, and further suppresses the radially outward displacement of the second portion 25. Therefore, opening from the second seam 22 of the cylindrical portion 20 can be further suppressed. In the above-mentioned Example 1, a protrusion 28 that is pressed into the housing 70 is provided on the outer surface of the first portion 24 of the cylindrical portion 20, but the protrusion 28 may also be provided on the outer surface of the cylindrical portion 20 in the vicinity of the first portion 24. In the above-mentioned first embodiment, a pair of the resilient contact pieces 31 are provided, but any other number of the resilient contact pieces 31 may be provided. In the above-mentioned first embodiment, the second seam 22 is shaped to extend along the circumferential direction, but it may be shaped to extend in another direction. In the above-mentioned first embodiment, the opening prevention portion 50 abuts against the outer surface of the second portion 25, but it may be configured to face the outer surface of the second portion 25 in close proximity. In the above-described first embodiment, the inclined portion 54 is inclined with respect to the outer surface of the second portion 25 parallel to the axial direction, but other configurations may be used as long as the inclined portion 54 is inclined with respect to the outer surface of the second portion 25. For example, the inclined portion 54 may be inclined with respect to the second portion 25 that is inclined with respect to the axial direction. [Explanation of symbols]
