Description

[Technical field]

[0001] The present invention relates to a board-to-board connector. [Background technology]

[0002] The connector described in Patent Document 1 has press-fit portions (press-fit terminals) at both ends of a press-fit contact, which are press-fitted into corresponding through-holes in a board. A lead-out portion is formed in the center of the press-fit contact, and an engagement portion is formed between the lead-out portion and the press-fit portion. A retaining means provided on the lead-out portion or the engagement portion is embedded in a fixing hole in an insulating housing.

[0003] In the above connector, when the press-fit portion is press-fitted into the through-hole of the board, the pressing jig presses the press-fit contact indirectly via the insulating housing. That is, the pressing force of the pressing jig is transmitted to the press-fit contact via the insulating housing, so that the press-fit portion is inserted into the through-hole in a press-fit state. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] JP 2008-53090 A Summary of the Invention [Problem to be solved by the invention]

[0005] If the insulating housing is deformed by compression when pressed by the driving jig, the deformation affects the mounting position of the press-fit portion relative to the through-hole of the board, and ultimately affects the distance between the two boards.

[0006] An embodiment of the present invention provides a board-to-board connector that can improve the accuracy of the mounting positions of terminals on a board. [Means for solving the problem]

[0007] One embodiment of the present invention provides a board-to-board connector (1) for connecting a first board (B1) having a first through hole (TH1) and a second board (B2) having a second through hole (TH2), the board-to-board connector (1) including contacts (3; 3Q; 3S; 3T; 3U; 3V; 3W) and an insulating housing (2). The contacts include a body portion (30), a first terminal (31) which is a press-fit terminal that can be press-fitted into the first through hole, a second terminal (32) which is a press-fit terminal that can be press-fitted into the second through hole, a first extension portion (41), and a second pressed portion (P2). The first terminal extends from the body portion along a first axis (L1). The second terminal extends from the body portion along a second axis (L2) offset from the first axis in the opposite direction to the first terminal. The first extension portion includes a top portion (41a) on which a first pressed portion (P1) is disposed, and extends from the main body portion in a direction opposite to the first terminal on the first axis. The second pressed portion is disposed on either the main body portion or a top portion (42a) of a second extension portion (42) protruding from the main body portion in a direction opposite to the second terminal on the second axis. The housing includes a retaining hole (26) in which the main body portion is housed and held in a state in which the first terminal, the second terminal, the first extension portion, and the second pressed portion are exposed to the outside, a first end face (E1) capable of facing the first board, and a second end face (E2) capable of facing the second board. The top portion of the first extension portion protrudes beyond the second end face of the housing.

[0008] According to this embodiment, first, the second pressed portion is pressed toward the second terminal using a jig, so that the second terminal can be press-fitted into the second through-hole of the second board without being pressed through the housing. Next, the first pressed portion is pressed toward the first terminal, so that the first terminal can be press-fitted into the first through-hole of the first board without being pressed through the housing. This makes it possible to suppress the influence of the housing on the mounting positions at which the first and second terminals, which are press-fit terminals, are mounted in the corresponding through-holes, and improve the accuracy of the mounting positions.

[0009] In addition, alphanumeric characters in parentheses indicate corresponding components in the embodiments described below, but this does not, of course, mean that the present invention should be limited to those embodiments. The same applies hereinafter in this section.

[0010] In one embodiment, the apex of the first extension portion can be pressed by the second substrate. According to this configuration, after the second terminal is press-fitted into the second through-hole of the second substrate, the first pressed portion can be directly pressed toward the first terminal by the second substrate, thereby press-fitting the first terminal into the first through-hole of the first substrate.

[0011] In one embodiment, the first extension portion can be inserted into a third through-hole (TH3) provided in the second substrate. According to this configuration, after the second terminal is press-fitted into the second through-hole of the second substrate, the top of the convex portion (first pressed portion) protruding from the third through-hole of the second substrate is directly pressed against the first terminal, thereby press-fitting the first terminal into the first through-hole of the first substrate.

[0012] In one embodiment, the housing is integrally formed from a single member, which can simplify the structure.

[0013] In one embodiment, the main body portion includes a first main body portion (30A) from which the first terminal extends, a second main body portion (30B) from which the second terminal extends, and a first elastic connecting portion (33) that elastically connects the first main body portion and the second main body portion. The retaining hole of the housing includes a fixing hole (26A) into which the first main body portion is press-fitted and fixed, and a loose-fit hole (26B) into which the second main body portion is fitted.

[0014] According to this configuration, the first elastic connecting portion can absorb any relative positional deviation between the first body portion and the second body portion, and therefore, when the first terminal is press-fitted into the first through-hole of the first board with the second terminal press-fitted into the second through-hole of the second board, it is possible to suppress the second terminal from being misaligned in the direction of the second axis with respect to the second board.

[0015] In one embodiment, the body portion includes a first body portion (30C; 30E) from which the first terminal extends, and a second body portion (30D; 30F) from which the second terminal extends. When viewed in a direction parallel to the first axis, the contact includes a connecting portion (34; 35) that connects the first body portion and the second body portion in an angled or U-shaped manner. This configuration can increase the degree of freedom in the layout of the first terminal and the second terminal.

[0016] In one embodiment, the connecting portion includes a second elastic connecting portion (36; 37) that elastically connects the first body portion and the second body portion. With this configuration, when the later press-fitted terminal out of the first and second terminals is press-fitted, it is possible to suppress a change in the press-fit position of the terminal that is press-fitted earlier.

[0017] One embodiment of the present invention provides a board-to-board connector (1X) for connecting a first board having a first through hole and a second board having a second through hole, the board-to-board connector including a contact (3X) and an insulating housing (2X) integrally formed from a single member. The contact includes a main body (30X), a first terminal (31), a second terminal (32D), and a first extension (41). The first terminal is a press-fit terminal that extends from the main body along a first axis (L1) and can be press-fitted into the first through hole. The second terminal extends from the main body along a second axis (L2) offset from the first axis in the opposite direction to the first terminal and can be inserted into the second through hole. The second terminal is a dip terminal that can be soldered to a surface (B2b) of the second board opposite to a surface (B2a) facing the housing. The first extension portion includes a top portion (41a) on which a first pressed portion (P1) is disposed, and extends on the first axis in a direction opposite to the first terminal. The housing includes a retaining hole (26X) in which the main body portion is housed and held with the first terminal, the second terminal, and the first extension portion exposed to the outside, a first end face (E1) capable of facing the first board, and a second end face (E2) capable of facing the second board. The top portion of the first extension portion protrudes beyond the second end face of the housing.

[0018] According to this configuration, after the second terminal, which is a DIP terminal, is inserted into the second through-hole of the second board, the first pressed portion is pressed toward the first terminal by the second board, so that the first terminal can be press-fitted into the first through-hole of the first board without pressing through the housing. This makes it possible to suppress the influence of the housing on the mounting position where the first terminal, which is a press-fit terminal, is mounted in the first through-hole, and improve the accuracy of the mounting position.

[0019] In one embodiment, the contact includes a second elastic connecting portion (38) that elastically connects the main body portion and the DIP terminal. With this configuration, when the second terminal, which is a DIP terminal, is inserted into the second through hole and soldered to the second board, the second board presses the first pressed portion toward the first terminal, so that the first terminal is press-fitted into the first through hole of the first board. At this time, the second elastic connecting portion can absorb any positional deviation between the first terminal and the second terminal in the direction parallel to the first axis, and the soldered portion around the second terminal, which is a DIP terminal, can be protected. Effect of the Invention

[0020] In the present invention, the accuracy of the mounting position of the terminals on the board can be improved. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

[0023] Fig. 1 is a perspective view of a board-to-board connector according to an embodiment of the present invention, and Fig. 2 is a cross-sectional view of the board-to-board connector.

[0024] 1 and 2, the board-to-board connector 1 includes an insulating housing 2 and a plurality of contacts 3. The housing 2 includes an upper surface 21, a lower surface 22, a front surface 23, a rear surface 24, a pair of side surfaces 25, a plurality of retaining holes 26 passing through the upper surface 21 and the lower surface 22, a pair of upper convex walls 27 protruding upward from the upper surface 21, and a pair of lower convex walls 28 protruding downward from the lower surface 22. The housing 2 is integrally formed from a single member. The plurality of retaining holes 26 are aligned in the left-right direction, and each of them houses and holds a contact 3.

[0025] An upper surface of the upper convex wall 27 constitutes a second end face E2 located at the uppermost position in the housing 2. A lower surface of the lower convex wall 28 constitutes a first end face E1 located at the lowermost position in the housing 2. The first end face E1 can face the first substrate B1, and the second end face E2 can face the second substrate B2 (see FIG. 3C).

[0026] 2, the contact 3 includes a substantially rectangular main body 30, a first terminal 31 which is a press-fit terminal that can be press-fitted into a first through-hole TH1 (see FIG. 3C) of the first substrate B1, a second terminal 32 which is a press-fit terminal that can be press-fitted into a second through-hole TH2 (see FIG. 3C) of the second substrate B2, a first extension portion 41 including a first pressed portion P1, and a second extension portion 42 including a second pressed portion P2. The first terminal 31 and the second terminal 32 extend from the main body 30 in opposite directions to each other.

[0027] The first terminal 31 extends downward from the main body 30 along the first axis L1. The first terminal 31 includes a press-fit portion 31a elastically deformable in a first orthogonal direction V1 perpendicular to the first axis L1, and a cavity portion 31b. The press-fit portion 31a has a width in the first orthogonal direction V1 greater than the width of other portions. The press-fit portion 31a elastically presses into contact with a conductor portion (not shown) on the inner surface of the first through-hole TH1. The cavity portion 31b penetrates in a second orthogonal direction (direction perpendicular to the paper surface) perpendicular to the first axis L1 and the first orthogonal direction V1, and extends along the first axis L1.

[0028] The second terminal 32 extends upward (in the opposite direction to the first terminal 31) from the main body 30 along a second axis L2 offset from the first axis L1. The second terminal 32 includes a press-fit portion 32a elastically deformable in a first orthogonal direction V1 perpendicular to the second axis L2, and a cavity portion 32b. The press-fit portion 32a has a width in the first orthogonal direction V1 greater than the width of other portions. The press-fit portion 32a elastically presses into contact with a conductor portion (not shown) on the inner surface of the second through hole TH2. The cavity portion 32b penetrates in a second orthogonal direction (direction perpendicular to the paper surface) perpendicular to both the second axis L2 and the first orthogonal direction V1, and extends along the second axis L2.

[0029] The first extension portion 41 extends from the main body 30 in the opposite direction (upward) of the first terminal 31 on the first axis L1. The first extension portion 41 includes a top portion 41a on which the first pressed portion P1 is disposed. The top portion 41a of the first extension portion 41 protrudes upward beyond the second end surface E2 of the housing 2.

[0030] The second extending portion 42 extends on the second axis L2 from the main body portion 30 in the opposite direction (downward) of the second terminal 32. The second extending portion 42 includes a top portion 42a on which the second pressed portion P2 is disposed.

[0031] The retaining hole 26 of the housing 2 accommodates and retains the main body 30 of the contact 3 with the first terminal 31, the second terminal 32, the first extending portion 41 and the second pressed portion P2 of the contact 3 exposed to the outside.

[0032] 3A to 3C sequentially show the steps of connecting a first board B1 and a second board B2 using the board-to-board connector 1. FIG.

[0033] By using a jig (not shown) to press the second pressed portion P2 toward the second terminal 32, the second terminal 32 can be pressed into the second through hole TH2 of the second substrate B2 and press-fitted without being pressed through the housing 2 (see Figure 3A).

[0034] Next, the first pressed portion P1 is pressed toward the first terminal 31 by the second board B2, so that the first terminal 31 can be pressed into the first through hole TH1 of the first board B1 and press-fitted without being pressed through the housing 2 (see Figures 3B and 3C).

[0035] According to this embodiment, the accuracy of the mounting positions of the first terminal 31 and the second terminal 32, which are press-fit terminals, can be improved by suppressing the influence of the housing 2 on the mounting positions at which the first terminal 31 and the second terminal 32 are mounted in the corresponding through holes TH1, TH2. In addition, since the housing 2 is integrally formed from a single member, the structure can be simplified.

[0036] Next, Fig. 4 is a cross-sectional view of a board-to-board connector 1 according to another embodiment of the present invention. The contact 3Q in the embodiment of Fig. 4 is mainly different from the contact 3 in the embodiment of Fig. 2 in the following respects. That is, in the contact 3 in the embodiment of Fig. 2, the second extension portion 42 is provided with the second pressed portion P2 disposed at the top portion 42a. In contrast, in the contact 3Q in the embodiment of Fig. 4, the second extension portion 42 is not provided, and the second pressed portion P2 is disposed in the main body portion 30 of the contact 3Q. In this embodiment as well, it is possible to directly press the second pressed portion P2 using a jig (shown) that can be inserted into the holding hole 26.

[0037] Next, Fig. 5 is a cross-sectional view of a board-to-board connector 1 according to yet another embodiment of the present invention. The contact 3R in the embodiment of Fig. 5 is mainly different from the contact 3 in the embodiment of Fig. 2 in that the first extension portion 41 extends so as to be insertable through a third through hole TH3 provided in the second board B2.

[0038] According to this embodiment, after the second terminal 32 is press-fitted into the second through-hole TH2 of the second substrate B2, the top portion 41a (first pressed portion P1) of the first extending portion 41 protruding from the third through-hole TH3 of the second substrate B2 can be directly pressed toward the first terminal 31. This allows the first terminal 31 to be pressed and press-fitted into the first through-hole TH1 of the first substrate B1 without going through the second substrate B2.

[0039] Next, FIG. 6 is a cross-sectional view of a board-to-board connector 1 according to still another embodiment of the present invention.

[0040] The configuration of the embodiment of FIG. 6 differs from that of the embodiment of FIG. 2 mainly in the following points. That is, the main body portion 30 of the contact 3S includes a first main body portion 30A to which the first terminal 31 extends, and a second main body portion 30B to which the second terminal 32 extends. The contact 3S further includes a first elastic connecting portion 33 that elastically connects the first main body portion 30A and the second main body portion 30B. The first elastic connecting portion 33 has, for example, a bent or curved shape such as a mountain shape, and is elastically deformable. In addition, the holding hole 26 of the housing 2 includes a fixing hole 26A into which the first main body portion 30A is press-fitted and fixed, and a loose-fit hole 26B into which the second main body portion 30B is fitted.

[0041] According to this embodiment, the relative positional deviation between the first main body portion 30A and the second main body portion 30B can be absorbed by the first elastic connecting portion 33. Therefore, although not shown, when the first terminal 31 is press-fitted into the first through-hole TH1 of the first substrate B1 in a state in which the second terminal 32 is press-fitted into the second through-hole TH2 of the second substrate B2, it is possible to suppress the second terminal 32 from being misaligned in the direction of the second axis L2 with respect to the second substrate B2.

[0042] 7A and 7B are perspective views, seen from different angles, of a contact 3T in a board-to-board connector according to still another embodiment of the present invention.

[0043] As shown in FIG. 7A and FIG. 7B, the body portion 30 of the contact 3T includes a first body portion 30C from which the first terminal 31 extends, and a second body portion 30D from which the second terminal 32 extends. When viewed in a direction parallel to the first axis L1, the contact 3T further includes a connecting portion 34 that connects the first body portion 30C and the second body portion 30D in an angled shape. According to this embodiment, the degree of freedom in the layout of the first terminal 31 and the second terminal 32 can be increased. In addition, the degree of freedom in the layout position of the through holes of each board is increased. In addition, a second extension portion having a top portion where the second pressed portion P2 is located may be provided on the second axis L2.

[0044] Next, FIGS. 8A and 8B are perspective views, seen from different angles, of a contact 3U in a board-to-board connector according to still another embodiment of the present invention.

[0045] As shown in FIG. 8A and FIG. 8B, the main body 30 of the contact 3U includes a first main body 30E from which the first terminal 31 extends, and a second main body 30F from which the second terminal 32 extends. When viewed in a direction parallel to the first axis L1, the contact 3U includes a connecting portion 35 that connects the first main body 30E and the second main body 30F in a U-shape. The connecting portion 35 is formed, for example, in a semicircular arc shape. According to this embodiment, the degree of freedom in the layout of the first terminal 31 and the second terminal 32 can be increased. As a result, the degree of freedom in the layout position of the through holes of each board is increased. In addition, a second extension portion having a top portion where the second pressed portion P2 is located may be provided on the second axis L2.

[0046] Next, Fig. 9 is a perspective view of a contact 3V in a board-to-board connector according to yet another embodiment of the present invention. The contact 3V in the embodiment of Fig. 9 is mainly different from the contact 3T in the embodiment of Fig. 7A in that the contact 3V includes a second elastic connecting portion 36 as the connecting portion 34 that connects the first body portion 30C and the second body portion 30D in an angled manner.

[0047] According to this embodiment, it is possible to increase the degree of freedom in the layout of the first terminal 31 and the second terminal 32. Furthermore, the relative positional deviation between the first body portion 30C and the second body portion 30D can be absorbed by the elastic deformation of the second elastic connecting portion 36. Therefore, although not shown, when a terminal to be press-fitted later is press-fitted, it is possible to suppress a change in the press-fit position of the terminal that is press-fitted earlier.

[0048] Next, Fig. 10 is a perspective view of a contact 3W in a board-to-board connector according to yet another embodiment of the present invention. The contact 3W in the embodiment of Fig. 10 is mainly different from the contact 3U in the embodiment of Fig. 8A in that the contact 3W includes a second elastic connecting portion 37 as a connecting portion 35 that connects the first body portion 30E and the second body portion 30F in a U-shape.

[0049] According to this embodiment, it is possible to increase the degree of freedom in the layout of the first terminal 31 and the second terminal 32. Furthermore, the relative positional deviation between the first body portion 30E and the second body portion 30F can be absorbed by the elastic deformation of the second elastic connecting portion 37. Therefore, although not shown, when the terminal to be press-fitted first is press-fitted, it is possible to suppress a change in the press-fit position of the terminal that is press-fitted first from being changed.

[0050] Next, Fig. 11A is a cross-sectional view of a board-to-board connector 1X according to yet another embodiment of the present invention, and Fig. 11B is a process diagram when using the board-to-board connector 1X.

[0051] The board-to-board connector 1X of the embodiment in Fig. 11A mainly differs from the board-to-board connector 1 of the embodiment in Fig. 4 in the following respects. That is, as shown in Fig. 11A, the board-to-board connector 1X includes a housing 2X and a contact 3X. The contact 3X includes a main body portion 30X, a first terminal 31, a second terminal 32D, a first extension portion 41, and a second elastic connecting portion 38. The first terminal 31 is a press-fit terminal that extends from the main body portion 30X along the first axis L1 and can be press-fitted into a first through-hole (not shown) of the first board.

[0052] The second terminal 32D extends from the main body 30X along a second axis L2 offset from the first axis L1 in the opposite direction to the first terminal 31, and can be inserted through the second through hole TH2 of the second board B2. The second terminal 32D is a DIP terminal that can be soldered to a surface B2b of the second board B2 opposite to a surface B2a facing the housing 2.

[0053] The second elastic connecting portion 38 elastically connects the main body portion 30X and the second terminal 32D. The second elastic connecting portion 38 has a bent or curved shape such as a mountain shape. The first extending portion 41 includes a top portion 41a where the first pressed portion P1 is disposed, and extends in the opposite direction to the first terminal 31 on the first axis L1.

[0054] The housing 2X includes a retaining hole 26X in which the main body 30X of the contact 3X is held with the first terminal 31, the second terminal 32D, and the first extension 41 exposed to the outside, a first end face E1 that can face the first board, and a second end face E2 that can face the second board B2. The top 41a of the first extension 41 protrudes beyond the second end face of the housing 2X. The main body 30X of the contact 3X is press-fitted and fixed in the retaining hole 26X and held. The retaining hole 26X includes a bottom 26Xa that positions the main body 30X of the contact 3X in a direction parallel to the first axis L1.

[0055] According to this embodiment, after the second terminal 32D, which is a DIP terminal, is inserted into the second through-hole TH2 of the second substrate B2 (see FIG. 11B), the first pressed portion P1 is pressed toward the first terminal 31 by the second substrate B2, so that the first terminal 31 can be press-fitted into the first through-hole (not shown) of the first substrate without being pressed through the housing 2X. This makes it possible to suppress the influence of the housing 2X on the mounting position where the first terminal 31, which is a press-fit terminal, is mounted in the first through-hole, thereby improving the accuracy of the mounting position.

[0056] Furthermore, in a state in which the second terminal 32D, which is a DIP terminal, is inserted into the second through-hole TH2 and soldered to the second board B2, when the second board B2 presses the first pressed portion P1 toward the first terminal 31 to press-fit the first terminal 31 into the first through-hole (not shown) of the first board, any positional deviation between the first terminal 31 and the second terminal 32D in the direction parallel to the first axis L1 can be absorbed by the second elastic connecting portion 38. This makes it possible to protect the soldered portion around the second terminal 32D, which is a DIP terminal.

[0057] The present invention is not limited to the above embodiment. For example, in the embodiment of Fig. 11A, the second terminal 32D and the main body 30X may be directly connected without providing the second elastic connecting portion 38. Also, the first extension portion 41 in the embodiment of Fig. 11A may be configured to be able to pass through the third through hole TH3 of the second board B2, as in the embodiment of Fig. 5. In addition, the present invention may be modified in various ways within the scope of the claims. [Explanation of symbols]
