[0001] The present invention relates to a connector mounted on a board. [Background technology]
[0002] For example, Patent Document 1 discloses a connector of this type.
[0003] Referring to FIG. 13, the connector 90 of Patent Document 1 is a so-called on-board connector mounted on a substrate (not shown). The connector 90 includes a housing 92 made of resin and a plurality of terminals 94 held by the housing 92. The terminals 94 form two terminal rows, each extending along the pitch direction (Y direction). The terminals 94 in each terminal row include a plurality of first terminals 96 and a plurality of second terminals 98. The second terminals 98 have a shape obtained by rotating the first terminals 96 by 180 degrees around an axis extending parallel to the up-down direction (Z direction). In each terminal row, the first terminals 96 and the second terminals 98 are arranged alternately. The above-mentioned alternating arrangement (staggered arrangement) can shorten the distance between two adjacent terminals 94 in the pitch direction. In other words, the terminals 94 can be arranged at a narrow pitch, thereby reducing the size of the connector 90 in the pitch direction. [Prior art documents] [Patent documents]

[0011] Referring to Figure 1 together with Figure 3, a connector 10 according to an embodiment of the present invention is an on-board connector mounted on a substrate 82. The connector 10 can be mated with a mating connector 70 mounted on a mating substrate 84 along the vertical direction. The vertical direction in this embodiment is the Z direction. In this embodiment, the up direction is the +Z direction, and the down direction is the -Z direction. Terms such as the up and down direction do not indicate absolute positional relationships with respect to the ground, but merely indicate relative positional relationships in the drawing.
[0012] 1 and 2, the connector 10 of this embodiment includes a housing 20 made of an insulator, a plurality of terminals 50 made of a conductor, and two hold-downs 60 made of a conductor. The hold-downs 60 are attached to both ends of the housing 20 in a pitch direction perpendicular to the up-down direction, reinforcing the housing 20. The pitch direction in this embodiment is the Y direction. The connector 10 of this embodiment includes only the above-described components. However, the present invention is not limited to this. For example, the connector 10 may include other components in addition to the above-described components. Furthermore, the hold-downs 60 may be provided as needed.
[0013] The mating connector 70 (see FIG. 6) of this embodiment will be described below.
[0014] 6, a mating connector 70 of this embodiment includes a mating housing 72 made of an insulator, a plurality of mating terminals 76 made of a conductor, and two mating hold-downs 78 also made of a conductor. The mating hold-downs 78 are attached to both ends of the mating housing 72 in the pitch direction, and reinforce the mating housing 72.
[0015] 3, mating terminals 76 are provided corresponding to the terminals 50, respectively. When connector 10 and mating connector 70 are mated with each other, each terminal 50 comes into contact with a corresponding mating terminal 76, thereby electrically connecting board 82 and mating board 84 to each other. The mating connector 70 of this embodiment has the above-described structure. However, the structure of mating connector 70 of the present invention is not particularly limited.
[0016] The basic structure of the housing 20 of this embodiment will now be described.
[0017] 1 and 2, the housing 20 of this embodiment is a single member molded from resin, and has a peripheral wall portion 22, an island-shaped portion 26, and a bottom portion 29. The peripheral wall portion 22 has two long wall portions 23 and two short wall portions 24. That is, the housing 20 has two long wall portions 23 and two short wall portions 24.
[0018] Each of the long wall portions 23 in this embodiment extends along the pitch direction. Each of the short wall portions 24 in this embodiment extends along a width direction perpendicular to both the up-down direction and the pitch direction, and connects two long wall portions 23 to each other in the width direction. The width direction in this embodiment is the X direction. In this embodiment, the left side is the +X side, and the right side is the -X side. The size of the long wall portion 23 in the pitch direction is larger than the size of the short wall portion 24 in the width direction. In other words, the long wall portion 23 is longer than the short wall portion 24.
[0019] The peripheral wall portion 22 of this embodiment is formed by long wall portions 23 and short wall portions 24, and has a rectangular frame shape without any discontinuities in the horizontal plane (XY plane) defined by the pitch direction and width direction. However, the present invention is not limited to this, and the structure of the peripheral wall portion 22 can be modified as necessary.
[0020] As shown in FIG. 1 , the island-shaped portion 26 of this embodiment is surrounded by the long wall portion 23 and the short wall portion 24 in the horizontal plane and extends along the pitch direction. An intermediate hole 27 is formed in the island-shaped portion 26. The intermediate hole 27 is located in the middle of the island-shaped portion 26 in the width direction. The intermediate hole 27 extends along the pitch direction and penetrates the island-shaped portion 26 in the up-down direction. As a result, two side walls 262 are formed in the island-shaped portion 26. The two side walls 262 are located on both sides of the intermediate hole 27 in the width direction and extend along the pitch direction. The island-shaped portion 26 of this embodiment has the above-described structure. However, the present invention is not limited to this. For example, the intermediate hole 27 may be formed as needed. Furthermore, the island-shaped portion 26 may be formed as needed.
[0021] 2, the two long wall portions 23 in this embodiment are made up of a right long wall portion 23R and a left long wall portion 23L. The two side wall portions 262 of the island-shaped portion 26 in this embodiment are made up of a right wall portion 26R and a left wall portion 26L. The right long wall portion 23R and the right wall portion 26R face each other in the width direction. The left long wall portion 23L and the left wall portion 26L face each other in the width direction.
[0022] 1 and 2, the bottom portion 29 in this embodiment is located below the housing 20. The island-shaped portion 26 is connected to each of the long wall portion 23 and the short wall portion 24 by the bottom portion 29. However, the present invention is not limited to this. For example, the island-shaped portion 26 may be connected to only the short wall portion 24 by the bottom portion 29.
[0023] The terminal 50 of this embodiment will be described below.
[0024] The terminal 50 of this embodiment includes a plurality of first terminals 50F and a plurality of second terminals 50S. As can be seen from FIGS. 10 and 12, the second terminals 50S have a shape obtained by rotating the first terminal 50F by 180° around an axis extending parallel to the vertical direction. In other words, the first terminals 50F and the second terminals 50S are the same component, although they are arranged in different positions. However, the present invention is not limited to this. For example, the first terminals 50F and the second terminals 50S may have different structures.
[0025] The structure of one of the terminals 50 (first terminal 50F) of this embodiment will be described below. The following description is applicable to each of the terminals 50 including the second terminal 50S.
[0026] 9 and 10, terminal 50 of this embodiment is not a contact formed by cutting out a single metal plate, but a contact formed by bending a single metal plate (hereinafter referred to as a "bent contact"). In other words, terminal 50 is a single metal plate with a bent portion. Terminal 50 of this embodiment has fixed portion 52, held portion 54, spring portion 56, and two contacts 58.
[0027] 3, the terminal 50 of this embodiment is surface-mounted on a substrate 82. More specifically, the fixed portion 52 of this embodiment is fixed to the substrate 82 by soldering. As shown in FIG. 9, the fixed portion 52 of this embodiment has a rectangular flat plate shape. However, the present invention is not limited to this. For example, the method of fixing the fixed portion 52 to the substrate 82 (see FIG. 3) is not particularly limited.
[0028] 9 and 10, the held portion 54 in this embodiment extends from the fixed portion 52. More specifically, the held portion 54 extends upward in an arc from the end of the fixed portion 52 in the width direction, and then extends straight upward. Two press-fit protrusions 542 are provided on the held portion 54. The press-fit protrusions 542 protrude on both sides in the pitch direction. The held portion 54 in this embodiment has the above-mentioned structure. However, as long as the held portion 54 partially protrudes on both sides in the pitch direction, the structure of the held portion 54 in the present invention is not particularly limited.
[0029] The spring portion 56 extends from the held portion 54. More specifically, the spring portion 56 in this embodiment has a lower extension portion 562, a bottom portion 564, and an upper extension portion 566. The lower extension portion 562 extends in an arc from the upper end of the held portion 54 in the width direction away from the fixed portion 52, and then extends downward. The bottom portion 564 extends from the lower end of the lower extension portion 562 in the width direction while moving away from the held portion 54. The upper extension portion 566 extends upward from one of the ends of the bottom portion 564 that is farthest from the held portion 54.
[0030] The spring portion 56 of the present embodiment has the above-described structure. The spring portion 56 of the present embodiment has a U-shape as a whole and is easily elastically deformed. However, as long as the spring portion 56 has spring properties, the structure of the spring portion 56 of the present invention is not particularly limited.
[0031] The contact 58 is supported by the spring portion 56 and is movable in response to the elastic deformation of the spring portion 56. Specifically, one of the two contacts 58 in this embodiment is a main contact 582 provided on the upper extension portion 566. The main contact 582 moves relatively significantly in the width direction in response to the elastic deformation of the spring portion 56. The other of the two contacts 58 is a sub-contact 584 provided on the lower extension portion 562. The sub-contact 584 hardly moves even when the spring portion 56 is elastically deformed. The contact 58 in this embodiment is provided as described above. However, the present invention is not limited to this. For example, the number of contacts 58 may be one.
[0032] The arrangement of the terminals 50 in this embodiment will be described below.
[0033] Referring to FIG. 2, the terminals 50 of this embodiment are divided into two terminal rows 50R. The two terminal rows 50R consist of a right terminal row 50R located on the right side of the housing 20 in the width direction and a left terminal row 50R located on the left side of the housing 20 in the width direction. In each terminal row 50R, the terminals 50 are arranged linearly along the pitch direction. Each terminal row 50R consists of a plurality of first terminals 50F and a plurality of second terminals 50S. In each terminal row 50R, the first terminals 50F and the second terminals 50S are alternately arranged at equal intervals in the pitch direction. Referring to FIGS. 7 and 8, the first terminals 50F and the second terminals 50S are arranged so that the fixed portions 52 face opposite each other in the width direction.
[0034] As a result of the above-described arrangement, the fixed portions 52 of two terminals 50 adjacent to each other in the pitch direction (i.e., the first terminal 50F and the second terminal 50S) are located at different positions in the width direction. That is, the terminals 50 in this embodiment are arranged alternately (staggered), which allows the terminals 50 to be arranged at a narrow pitch.
[0035] 11, in each of the terminals 50 of this embodiment, the size in the pitch direction (width WF) of the fixed portion 52 is larger than the size in the pitch direction (width WS) of the spring portion 56. In particular, according to this embodiment, the size in the pitch direction (width) of all parts of the spring portion 56 is smaller than the width WF of the fixed portion 52. Furthermore, the width WS of the spring portion 56 is constant throughout the entire spring portion 56 except for the upper portion of the upper extension portion 566. The width of the upper portion of the upper extension portion 566 is equal to or smaller than the width WS.
[0036] According to the above-described structure, the fixed portion 52 can be firmly fixed to the substrate 82 (see FIG. 3), while the pitch between the terminals 50 can be reduced. Furthermore, according to this embodiment, since each of the terminals 50 is a bending contact, it is easy to make the width WS narrower than the width WF. However, the present invention is not limited to this. For example, the width WF may be equal to the width WS.
[0037] 4, the housing 20 is formed with a plurality of holding portions 32 corresponding to the terminals 50, and a plurality of accommodating portions 34 corresponding to the terminals 50. Referring to FIGS. 7 and 8, the holding portions 32 and the accommodating portions 34 are spaces that open upward and downward from the housing 20. Each of the terminals 50 in this embodiment is inserted into the corresponding holding portion 32 and accommodating portion 34 from below.
[0038] 7 and 8 together with Fig. 10, each holding portion 32 of the terminal 50 is press-fitted into the corresponding holding portion 32 from below, thereby firmly holding the terminal 50. That is, each holding portion 32 holds the held portion 54 of the corresponding terminal 50.
[0039] Instead of press-fitting the retained portions 54, each of the terminals 50 may be retained in the retaining portion 32 by insert-molding the retained portions 54, which have protrusions for preventing removal. In this case, however, during insert molding, the spring portions 56 of the terminals 50 must be surrounded by a mold to prevent the spring portions 56 from being embedded in the resin. As a result, an unnecessarily large space may be formed around the spring portions 56, which may increase the pitch between the terminals 50. Therefore, this embodiment is preferable from the viewpoint of arranging the terminals 50 at a narrow pitch.
[0040] When the held portion 54 is press-fit into the holding portion 32, each spring portion 56 of the terminal 50 is received in the corresponding accommodating portion 34. That is, each accommodating portion 34 receives the spring portion 56 of the corresponding terminal 50. More specifically, each accommodating portion 34 has a receiving portion 342, a groove portion 344, and an allowing portion 346. The lower extension portion 562, the bottom portion 564, and the upper extension portion 566 of each spring portion 56 are received in the receiving portion 342, the groove portion 344, and the allowing portion 346 of the corresponding accommodating portion 34, respectively. The inner wall surface in the width direction of each allowing portion 346 is far away from the upper end of the upper extension portion 566 in the width direction, allowing movement of the upper extension portion 566 as the spring portion 56 elastically deforms.
[0041] Referring to Fig. 4, the housing 20 of this embodiment is formed with two first holding rows (holding rows) 32F and two second holding rows (holding rows) 32S. Each of the holding rows 32F, 32S is a row made up of a plurality of holding portions 32 and extends along the pitch direction. In other words, the holding portions 32 in each of the holding rows 32F, 32S are arranged linearly along the pitch direction. Referring to Fig. 5, each of the holding portions 32 in the first holding row 32F holds the held portion 54 of the first terminal 50F. Each of the holding portions 32 in the second holding row 32S holds the held portion 54 of the second terminal 50S.
[0042] 4, one of the two first retaining rows 32F is formed on the left long wall portion 23L, and one of the two second retaining rows 32S is formed on the left wall portion 26L of the island-shaped portion 26. The other of the two first retaining rows 32F is formed on the right wall portion 26R of the island-shaped portion 26, and the other of the two second retaining rows 32S is formed on the right long wall portion 23R.
[0043] The retaining portions 32 of the first retaining row 32F of the left long wall portion 23L and the retaining portions 32 of the second retaining row 32S of the left side wall portion 26L each retain the retained portions 54 of the terminals 50 of one of the two terminal rows 50R (the left terminal row 50R). The retaining portions 32 of the first retaining row 32F of the right side wall portion 26R and the retaining portions 32 of the second retaining row 32S of the right long wall portion 23R each retain the retained portions 54 of the terminals 50 of the other of the two terminal rows 50R (the right terminal row 50R).
[0044] According to this embodiment, by forming two first retention rows 32F and two second retention rows 32S, two terminal rows 50R can be provided, each extending linearly in the pitch direction. That is, the number of terminal rows 50R in this embodiment is two. However, the present invention is not limited to this. For example, the number of terminal rows 50R may be one. In this case, the number of first retention rows 32F may be one, and the number of second retention rows 32S may be one. For example, without providing an island-shaped portion 26, the first retention row 32F may be provided on the left long wall portion 23L, and the second retention row 32S may be provided on the right long wall portion 23R.
[0045] According to this embodiment, a plurality of retaining portions 32 are formed on each of the two long wall portions 23 and the two side wall portions 262. However, the present invention is not limited to this. For example, only one retaining portion 32 may be formed on each of the two long wall portions 23 and the two side wall portions 262. However, in this case, even if the pitch between the terminals 50 is narrowed, the size of the connector 10 in the pitch direction remains almost unchanged. The present invention is suitable for a connector 10 in which a large number of retaining portions 32 are formed on each of the two long wall portions 23 and the two side wall portions 262.
[0046] In this embodiment, the accommodating sections 34 are divided into two rows corresponding to the two terminal rows 50R. The accommodating sections 34 in each row are arranged linearly along the pitch direction. However, the present invention is not limited to this. For example, when the number of terminal rows 50R is one, the accommodating sections 34 may be arranged in a single row along the pitch direction.
[0047] 5, according to this embodiment, two storage sections 34 adjacent to each other in the pitch direction are located at substantially the same position in the width direction. However, the present invention is not limited to this. For example, two storage sections 34 adjacent to each other in the pitch direction may be located at least partially at the same position in the width direction.
[0048] 5 together with Figures 7 and 8, a partition wall 38 is provided between two accommodating sections 34 adjacent to each other in the pitch direction. Each partition wall 38 is located between the receiving section 342, the groove section 344, and the allowing section 346 of the two accommodating sections 34 adjacent to each other in the pitch direction, and reliably insulates two terminals 50 adjacent to each other in the pitch direction from each other. The provision of the partition wall 38 allows the pitch between the terminals 50 to be narrowed.
[0049] According to this embodiment, all of the retaining portions 32 in the retaining rows 32F, 32S are positioned completely differently from all of the accommodating portions 34 in the width direction and do not overlap. From another perspective, this arrangement means that for two terminals 50 adjacent to each other in the pitch direction, the retaining portion 32 that holds the retained portion 54 of one of these terminals 50 does not overlap in the width direction with the accommodating portion 34 that accommodates the spring portion 56 of the other of these terminals 50. More specifically, the retaining portion 32 that holds the retained portion 54 of the first terminal 50F and the accommodating portion 34 that accommodates the spring portion 56 of the second terminal 50S are offset from each other in the width direction so as not to overlap. Furthermore, the retaining portion 32 that holds the retained portion 54 of the second terminal 50S and the accommodating portion 34 that accommodates the spring portion 56 of the first terminal 50F are offset from each other in the width direction so as not to overlap each other.
[0050] 5, the retaining portion 32 of one of two terminals 50 (adjacent terminals 50) adjacent to each other in the pitch direction is separated in the pitch direction by a distance DS from the accommodating portion 34 of the other adjacent terminal 50. The distance DS becomes shorter as the pitch between the terminals 50 becomes narrower. If the position of the retaining portion 32 of one of the adjacent terminals 50 and the position of the accommodating portion 34 of the other adjacent terminal 50 overlap each other in a predetermined region PA in the width direction, the path through which resin flows in the predetermined region PA when molding the housing 20 will become narrow, which may prevent the partition wall 38 from being formed properly.
[0051] On the other hand, according to the present embodiment, even if the pitch between the terminals 50 is further narrowed, the path through which the resin flows can be sufficiently widened when molding the housing 20. As a result, the partition wall 38 located between two accommodating sections 34 adjacent to each other in the pitch direction can be kept thicker than necessary, thereby preventing deterioration of the strength of the housing 20. In other words, according to the present invention, it is possible to provide a connector 10 having a structure that allows the terminals 50 to be arranged at a narrower pitch.
[0052] According to this embodiment, in each terminal row 50R (see FIG. 4), the retaining portions 32 that retain the retained portions 54 of the first terminals 50F and the accommodating portions 34 that accommodate the spring portions 56 of the second terminals 50S are adjacent to each other across a linear boundary (first boundary) in the width direction. In each terminal row 50R, the entire first boundary is located on a single predetermined line PL that extends along the pitch direction. Similarly, in each terminal row 50R, the retaining portions 32 that retain the retained portions 54 of the second terminals 50S and the accommodating portions 34 that accommodate the spring portions 56 of the first terminals 50F are adjacent to each other across a linear boundary (second boundary) in the width direction. In each terminal row 50R, the entire second boundary is located on a single predetermined line PL that extends along the pitch direction.
[0053] However, the present invention is not limited to this. For example, the widthwise boundary of the retaining portion 32 that retains the retained portion 54 of the first terminal 50F may be spaced apart from the widthwise boundary of the accommodating portion 34 that accommodates the spring portion 56 of the second terminal 50S. Similarly, the widthwise boundary of the retaining portion 32 that retains the retained portion 54 of the second terminal 50S may be spaced apart from the widthwise boundary of the accommodating portion 34 that accommodates the spring portion 56 of the first terminal 50F. However, this embodiment is preferred from the viewpoint of minimizing an increase in the size of the connector 10 in the width direction.
[0054] Referring to FIG. 2, in this embodiment, the number of terminals 50 in the right terminal row 50R is equal to the number of terminals 50 in the left terminal row 50R. Each of the terminals 50 in the right terminal row 50R is located at the same position in the pitch direction as one of the terminals 50 in the left terminal row 50R. This arrangement allows the size of the connector 10 in the pitch direction to be reduced. However, the present invention is not limited to this. For example, each of the terminals 50 in the right terminal row 50R may be located at a different position in the pitch direction from any of the terminals 50 in the left terminal row 50R.
[0055] 7 and 8, in this embodiment, each of the first terminals 50F of the right-side terminal row 50R is located at the same position in the pitch direction as one of the first terminals 50F of the left-side terminal row 50R, and each of the second terminals 50S of the right-side terminal row 50R is located at the same position in the pitch direction as one of the second terminals 50S of the left-side terminal row 50R. This arrangement allows the fixed portions 52 of two terminals 50 located at the same position in the pitch direction to be soldered to locations on the board 82 (see FIG. 3) that are far apart from each other, thereby preventing short circuits between the terminals 50. However, the present invention is not limited to this. For example, each of the first terminals 50F of the right-side terminal row 50R may be located at the same position in the pitch direction as one of the second terminals 50S of the left-side terminal row 50R.
[0056] In addition to the various modifications already described, this embodiment can be further modified in various ways. For example, referring to Fig. 2, according to this embodiment, an intermediate hole 27 is formed in the island-shaped portion 26, and therefore, it is possible to visually check through the intermediate hole 27 whether the fixed portion 52 is properly soldered to the substrate 82 (see Fig. 3). However, the present invention is not limited to this. For example, the intermediate hole 27 may be formed as needed. [Explanation of symbols]
