[0009] [Description of Embodiments of the Invention] First, embodiments of the present invention will be described. Any combination of the following embodiments without causing contradiction is also included in the embodiments of the present invention. (1) The connector device of the present invention comprises: a first circuit board; a first housing; a first terminal part having a first terminal connection portion and a first circuit board connection portion fixedly mounted on the first circuit board, and assembled in the first housing; a second circuit board arranged at a right angle relative to the first circuit board; a second housing capable of fitting into the first housing; and a second terminal part having a second terminal connection portion capable of contacting the first terminal connection portion and a second circuit board connection portion fixedly mounted on the second circuit board, and assembled in the second housing. The second terminal connection portion and the second circuit board connection portion are arranged in a direction intersecting the second circuit board. The first terminal connection portion is housed within the first housing. A cutout portion for avoiding interference with the second terminal part is formed in the wall portion constituting the first housing.

[0010] According to this structure, with the first housing and the second housing fitted together to connect the first terminal connection portion and the second terminal connection portion, the second circuit board connection portion is configured to be arranged in a direction intersecting the second circuit board relative to the contact area of ​​the first terminal connection portion and the second terminal connection portion. This allows for miniaturization in the direction parallel to the second circuit board.

[0011] (2) In (1), preferably, the second terminal part is fitted relative to the first terminal part in a manner that approaches in a direction intersecting with the first circuit board, and a support wall is formed in the second housing, the support wall bearing the pressing force exerted from the first terminal part on the second terminal part during fitting. According to this structure, when the first terminal connection and the second terminal connection are fitted, even if the second terminal part is subjected to pressing force from the first terminal part, relative displacement of the second terminal part relative to the second housing can be prevented.

[0012] (3) In (1) or (2), preferably, the second housing is box-shaped, surrounding the first housing, and a recess is formed in the opposing wall portion of the second housing opposite to the second circuit board, the recess exposing the connection portion of the second circuit board connection portion to the outside of the second housing. With this structure, the connection status of the second circuit board connection portion and the second circuit board can be visually confirmed.

[0013] (4) In (1) or (2), preferably, the second terminal part approaches and engages with the first terminal part in a direction intersecting the first circuit board, the surface of the second circuit board connection portion is mounted on the second circuit board, and the second circuit board connection portion has an extension portion that protrudes towards the first circuit board than the second terminal connection portion. According to this structure, in the engagement direction of the first terminal connection portion relative to the second terminal connection portion, the engagement length of the second circuit board connection portion relative to the second circuit board can be ensured to be relatively long. Therefore, when the first terminal connection portion and the second terminal connection portion are connected, even if pressure is applied from the first terminal part to the second terminal part, the second terminal part can be reliably secured to the second circuit board beforehand.

[0014] (5) In (1) or (2), preferably, the pair of first terminal parts are arranged parallel to the first circuit board, the first circuit board connection portion having a quarter-circuit-shaped first bend and a first mounting portion, the first bend extending from the first terminal connection portion, the first mounting portion extending from the first bend parallel to the first circuit board, and the extending directions of the pair of first mounting portions being opposite to each other in the arrangement direction of the pair of first terminal parts. According to this structure, a longer creepage distance between the pair of first mounting portions can be ensured on the mounting surface of the first circuit board.

[0015] (6) In (1) or (2), preferably, the pair of second terminal parts are arranged parallel to the second circuit board, the second circuit board connection portion having a quarter-circuit-shaped second bend and a second mounting portion, the second bend extending from the second terminal connection portion, the second mounting portion extending from the second bend portion parallel to the second circuit board, and the extending directions of the pair of second mounting portions being opposite to each other in the arrangement direction of the pair of second terminal parts. According to this structure, a longer creepage distance between the pair of second mounting portions can be ensured on the mounting surface of the second circuit board.

[0016] (7) In (1) or (2), preferably, the second terminal component is assembled with the second terminal connector pressed into the second housing. The second terminal connector has two plate-shaped portions bent into a folded-back shape. One of the plate-shaped portions is connected to the second circuit board connector. A pressure-bearing surface is formed on the end face of the other plate-shaped portion. A pressing force is applied to the pressure-bearing surface to press the second terminal component into the second housing. According to this structure, the strength of the second terminal connector can be improved by making the second terminal connector folded back. In addition, by making it folded back, the pressure-bearing surface that is subjected to the pressing force during insertion is ensured, so the pressing force can be avoided when applying pressure to the second circuit board connector. Thus, the second terminal component can be pressed into the second housing without deforming or damaging the second circuit board connector.

[0017] [Detailed Description of Embodiments of the Invention] [Example 1] Reference Figures 1-9 The connector device of Embodiment 1, which embodies the present invention, will be described. The invention is not limited to these illustrations, but is shown by the claims, including all modifications within the same meaning and scope as the claims. In this Embodiment 1, regarding the front-to-back direction, Figures 1-6 In 8 and 9, the direction F is defined as forward. Regarding the up and down directions, ... Figures 1-3 In 5-9, the H direction is defined as upward. Regarding the left and right directions, ... Figures 1-7 The R direction in the code is defined as the right. The left and right directions and the width direction are used synonymously.

[0018] The connector device of this embodiment 1 includes a first circuit board 10, a first connector 15 mounted on a first mounting surface 11 of the first circuit board 10, a second circuit board 40, and a second connector 45 mounted on a second mounting surface 41 of the second circuit board 40.

[0019] like Figure 1 , 2As shown in Figure 4, the first circuit board 10 is positioned with its thickness direction facing the front-to-back direction, and its first mounting surface 11 is positioned facing forward. Figure 3 As shown, the first connector 15 includes a first housing 16 and a pair of first terminal parts 25. A pair of left and right first terminal storage chambers 17 with openings at both the front and rear ends are formed within the first housing 16. The first housing 16 has a rear storage portion 18 and a pair of left and right front storage portions 19. The rear storage portion 18 constitutes the rear end region of the left and right first terminal storage chambers 17. The front storage portions 19 extend forward from the front end of the rear storage portion 18. The pair of front storage portions 19 respectively constitute the front end region of the pair of first terminal storage chambers 17. The front storage portions 19 are in the shape of a rectangular tube with a height dimension larger than its width dimension.

[0020] The vertical dimensions of the rear storage section 18 are larger than those of the front storage section 19. For example... Figure 8 As shown, an inclined wall portion 20 is formed between the front end of the upper wall portion of the rear storage portion 18 and the rear end of the upper wall portion of the front storage portion 19. An inclined wall portion 20 is also formed between the front end of the lower wall portion of the rear storage portion 18 and the rear end of the lower wall portion of the front storage portion 19. A pair of first pressing holes 21 are formed in the inclined wall portions 20. The rear end of the first pressing hole 21 opens at the upper end of the first terminal storage chamber 17.

[0021] like Figure 2 , 8 As shown in Figure 9, a cutout 23 extending in the front-rear direction (orthogonal to the first mounting surface 11 of the first circuit board 10) is formed on the bottom wall portion 22 constituting the left and right front side storage portions 19. The cutout 23 opens on the front surface, upper surface, and lower surface of the bottom wall portion 22. The cutout 23 communicates with the front end region of the first terminal storage chamber 17 and the lower space outside the first housing 16. The cutout 23 opens towards the front of the first housing 16.

[0022] Terminal part 25 is a female single-piece component made of bent metal sheet. For example... Figure 3 , 4 As shown, the first terminal component 25 has a first terminal connection portion 26 and a first circuit board connection portion 30. The first circuit board connection portion 30 extends rearward from the first terminal connection portion 26. The first terminal connection portion 26 and the first circuit board connection portion 30 are arranged in a direction orthogonal to the first mounting surface 11. The first terminal connection portion 26 has a cylindrical support portion 27 with openings at both ends and a pair of elastic contact pieces 28 on the left and right sides. The pair of elastic contact pieces 28 extend forward in a cantilever shape from the front edge of the left and right side plates constituting the support portion 27. Figure 3 , 8 As shown, a first pressing protrusion 29 protruding forward is formed on the upper plate portion and the lower plate portion constituting the support portion 27.

[0023] The first circuit board connection portion 30, located on the right side of the first terminal part 25, extends rearward from the rear end edge of the rightmost plate portion 27R, one of the four plate portions constituting the support portion 27. The first circuit board connection portion 30 has a first plate-shaped base 31, a first bend portion 32, and a first mounting portion 33. The first plate-shaped base 31 is coplanarly connected to the rightmost plate portion 27R and extends rearward from the rear end edge of the rightmost plate portion 27R. The first bend portion 32 is a quarter-circuit shape and extends obliquely to the right rearward from the rear end edge of the first plate-shaped base 31. The first mounting portion 33 extends to the right from the extending end edge of the first bend portion 32 in a manner perpendicular to the first plate-shaped base 31. In the rightmost first terminal part 25, the first mounting portion 33 is located at the rightmost end of the support portion 27, furthest from the leftmost first terminal part 25. In the rightmost first terminal part 25, the extending direction of the first mounting portion 33 is away from the leftmost first terminal part 25.

[0024] The first circuit board connection portion 30, located on the left side of the first terminal part 25, extends rearward from the rear end edge of the left side plate portion 27L, one of the four plate portions constituting the support portion 27. The first circuit board connection portion 30 has a first plate-shaped base 31, a first bend portion 32, and a first mounting portion 33. The first plate-shaped base 31 is coplanarly connected to the left side plate portion 27L and extends rearward from the rear end edge of the left side plate portion 27L. The first bend portion 32 is a quarter-circuit arc and extends obliquely to the left rearward from the rear end edge of the first plate-shaped base 31. The first mounting portion 33 extends to the left from the extending end edge of the first bend portion 32 in a manner perpendicular to the first plate-shaped base 31. In the left side of the first terminal part 25, the first mounting portion 33 is located at the leftmost end of the support portion 27, furthest from the right side of the first terminal part 25. In the left side of the first terminal part 25, the extending direction of the first mounting portion 33 is away from the right side of the first terminal part 25.

[0025] The left and right first terminal parts 25 are respectively housed in a pair of first terminal housing chambers 17 from the rear of the first housing 16. The first terminal parts 25 housed in the first terminal housing chambers 17 are held in the first housing 16 by engaging the inner surfaces of the first pressing protrusions 29 with the upper and lower first pressing holes 21. As described above, the assembly of the first connector 15 is completed by housing the first terminal parts 25 in the first housing 16. With the first terminal parts 25 assembled in the first housing 16, the first plate-shaped base 31 of the first circuit board connection portion 30 and the support portion 27 of the first terminal connection portion 26 are disposed in the rear end side region of the first terminal housing chamber 17. An elastic contact piece 28 is disposed in the front end side region of the first terminal housing chamber 17. In the front-rear direction (the direction parallel to the second mounting surface 41 of the second circuit board 40), the elastic contact piece 28 is disposed in the same area as the cutout portion 23.

[0026] The first connector 15 is surface-mounted onto the first circuit board 10 with the opening at the rear end of the first terminal housing 17 facing the first circuit board 10. The first connector 15 is assembled by using reflow soldering to conductively fix the first mounting portion 33 to the first mounting surface 11.

[0027] The second circuit board 40 is positioned with its thickness direction facing vertically, and its second mounting surface 41 facing upwards, below the first connector 15. The second mounting surface 41 is perpendicular to the first mounting surface 11. Figures 5-7 As shown, the second connector 45 includes a second housing 46 and a pair of symmetrically arranged second terminal parts 55. A pair of second terminal receiving chambers 47 with rear-end openings are formed within the second housing 46. Figure 5 As shown, when viewed from the rear, the second terminal housing 47 is rectangular in shape, with its height dimension greater than its width dimension. Figure 8 , 9 As shown, the second housing 46 has a support wall 48 that closes the front end of the left and right second terminal receiving chambers 47.

[0028] like Figures 7-9 As shown, a pair of second press-in holes 50 are formed on the opposing wall portion 49, which is located on the lower surface opposite the second mounting surface 41, forming the outer wall portion of the second housing 46. The second press-in holes 50 are elongated in the front-rear direction and open on the upper and lower surfaces of the opposing wall portion 49. The second press-in holes 50 communicate with the lower space outside the second terminal housing 46 and the second terminal receiving chamber 47. A pair of recesses 51 are formed on the opposing wall portion 49, forming a recessed portion of the opposing wall portion 49. The right recess 51 is open on the right side and front surface of the second housing 46. The left recess 51 is open on the left side and front surface of the second housing 46. When viewing the second housing 46 from below (the side of the second circuit board 40), the second press-in holes 50 are positioned within the recesses 51.

[0029] The second terminal component 55 is a male single-piece component made of a bent metal sheet. The second terminal component 55 has a second terminal connection portion 56 and a second circuit board connection portion 62. The second circuit board connection portion 62 extends downward from the first terminal connection portion 26. The second terminal connection portion 56 and the second circuit board connection portion 62 are arranged in a direction orthogonal to the second mounting surface 41. Figure 6 , 7 As shown, the second terminal connection portion 56 has a folded-back portion 57 and a pair of left and right plate-shaped portions 58L and 58R extending downward parallel to each other from the folded-back portion 57. Figure 8 , 9As shown, a second pressing protrusion 59 protruding forward is formed at the front end of the lower end of the left and right plate-shaped portions 58L and 58R. A second pressing protrusion 59 protruding rearward is formed at the rear end of the lower end of the left and right plate-shaped portions 58L and 58R.

[0030] like Figure 7 As shown, the lower end surface of the left plate-shaped portion 58L of the pair of plate-shaped portions 58L and 58R of the second terminal part 55 located on the right side functions as a pressure-bearing surface 60. The lower end surface of the right plate-shaped portion 58R of the pair of plate-shaped portions 58L and 58R of the second terminal part 55 located on the left side also functions as a pressure-bearing surface 60. These pressure-bearing surfaces 60 are surfaces that receive pressing pressure in the pressing direction from a fixture or the like when the second terminal part 55 is pressed into the second pressing hole 50.

[0031] like Figure 6 , 7 As shown, the second circuit board connection portion 62, located on the right side of the second terminal component 55, extends downward from the lower edge of the right plate-shaped portion 58R, one of the pair of left and right plate-shaped portions 58L and 58R. The second circuit board connection portion 62 has a second plate-shaped base 63, a second bend 64, and a second mounting portion 65. The second plate-shaped base 63 is coplanarly connected to the right plate-shaped portion 58R and extends downward from the lower edge of the right plate-shaped portion 58R. The second bend 64 is a quarter-circuit shape and extends obliquely downward to the right from the lower edge of the second plate-shaped base 63. The second mounting portion 65 extends to the right from the extending edge of the second bend 64 in a manner perpendicular to the plate-shaped portion 58R. In the right-side second terminal component 55, the second mounting portion 65 is located at the rightmost end of the second circuit board connection portion 62, furthest from the left-side second terminal component 55. In the second terminal part 55 on the right, the second mounting portion 65 extends in a direction away from the second terminal part 55 on the left. The second mounting portion 65 has an extension portion 66 that extends rearward beyond the rear end of the second plate-shaped base 63 and the second bent portion 64.

[0032] The second circuit board connection portion 62, located on the left side of the second terminal component 55, extends downward from the lower edge of the left plate-shaped portion 58L, one of the pair of left and right plate-shaped portions 58L and 58R. The second circuit board connection portion 62 has a second plate-shaped base 63, a second bend 64, and a second mounting portion 65. The second plate-shaped base 63 is coplanarly connected to the left plate-shaped portion 58L and extends downward from the lower edge of the left plate-shaped portion 58L. The second bend 64 is a quarter-circuit shape and extends obliquely to the lower left from the lower edge of the second plate-shaped base 63. The second mounting portion 65 extends to the left from the extending edge of the second bend 64 in a manner perpendicular to the second plate-shaped base 63. In the left-side second terminal component 55, the second mounting portion 65 is located at the leftmost end of the second circuit board connection portion 62, furthest from the right-side second terminal component 55. In the second terminal part 55 on the left, the extension direction of the second mounting part 65 is away from the second terminal part 55 on the right. For example... Figure 1 , 6 As shown in Figures 8 and 9, the second mounting portion 65 has an extension portion 66 that extends further rearward than the rear end of the second plate-shaped base portion 63 and the second bent portion 64.

[0033] The left and right second terminal parts 55 are assembled to the second housing 46 by pressing the second terminal connection part 56 into the second press-in hole 50 from below the second housing 46. During pressing, a jig (not shown) is used to press the pressure surface 60 of the second terminal connection part 56. The second terminal parts 55 assembled to the second housing 46 are held in the second housing 46 by engaging the inner surface of the second press-in hole 50 with the front and rear pairs of second press-in protrusions 59. As described above, the assembly of the second connector 45 is completed by assembling the second terminal parts 55 to the second housing 46. With the second terminal parts 55 assembled to the second housing 46, the second terminal connection part 56 is housed in the second terminal housing chamber 47, and the second circuit board connection part 62 is disposed in the recess 51.

[0034] The second connector 45 is surface-mounted onto the second circuit board 40 with the recess 51 (opposing wall 49) of the second housing 46 facing the second circuit board 40. The second connector 45 is assembled by using reflow soldering to conductively fix the second mounting portion 65 to the second mounting surface 41.

[0035] When the first connector 15 and the second connector 45 are engaged, the second circuit board 40 moves rearward parallel relative to the first circuit board 10, and the first housing 16 is housed within the second housing 46. With the two connectors 15 and 45 engaged, the left and right pair of front-side receiving portions 19 respectively enter the left and right pair of second-terminal receiving chambers 47, and the elastic contact piece 28 of the first-terminal connection portion 26 elastically contacts it by clamping the second-terminal connection portion 56 from both sides. Since the second circuit board connection portion 62 extends downward from the lower end of the second-terminal connection portion 56, there is a possibility that the front-side receiving portion 19 and the second-terminal component 55 might interfere. However, because a cutout 23 for receiving the lower end of the second-terminal connection portion 56 is formed on the bottom wall portion 22 of the front-side receiving portion 19, the second-terminal component 55 will not interfere with the front-side receiving portion 19 (first housing 16).

[0036] Furthermore, when the first terminal part 25 and the second terminal part 55 are connected, a pressing force from the side of the first terminal part 25 forward is applied to the second terminal part 55 due to the frictional resistance caused by the elastic force of the elastic contact piece 28. However, because the front edge of the second terminal connection portion 56 abuts against the support wall portion 48 of the second housing 46, the second terminal part 55 cannot tilt or misalign forward relative to the second housing 46.

[0037] The connector device of this embodiment 1 includes a first circuit board 10, a first connector 15 mounted on the first circuit board 10, a second circuit board 40 arranged at right angles to the first circuit board 10, and a second connector 45 mounted on the second circuit board 40. The first connector 15 is constructed by assembling a first terminal part 25 to a first housing 16. The first terminal part 25 has a first terminal connection portion 26 and a first circuit board connection portion 30 fixedly mounted to the first circuit board 10. The second connector 45 is constructed by assembling a second terminal part 55 that can connect to the first terminal part 25 to a second housing 46 that can fit into the first housing 16. The second terminal part 55 has a second terminal connection portion 56 that connects to the first terminal connection portion 26 and a second circuit board connection portion 62 fixedly mounted to the second circuit board 40.

[0038] The second terminal connection portion 56 and the second circuit board connection portion 62 are arranged in a vertical direction intersecting the second mounting surface 41 of the second circuit board 40. The first terminal connection portion 26 is housed within the first housing 16. A cutout portion 23 for avoiding interference with the second terminal component 55 is formed in the bottom wall portion 22 constituting the first housing 16. According to this structure, when the first housing 16 and the second housing 46 are fitted together to connect the first terminal connection portion 26 and the second terminal connection portion 56, the second circuit board connection portion 62 is arranged in a vertical direction intersecting the second circuit board 40 relative to the contact areas of the first terminal connection portion 26 and the second terminal connection portion 56. As a result, miniaturization can be achieved in the front-back and left-right directions parallel to the second circuit board 40.

[0039] The second terminal part 55 is fitted relative to the first terminal part 25 in a forward-backward direction intersecting the first circuit board 10. A support wall portion 48 is formed in the second housing 46, which bears the pressing pressure exerted by the first terminal part 25 on the second terminal part 55 during fitting. According to this structure, when the first terminal connection portion 26 and the second terminal connection portion 56 are fitted together, even if the second terminal part 55 is subjected to pressing pressure from the first terminal part 25, forward displacement of the second terminal part 55 relative to the second housing 46 can be prevented.

[0040] The second housing 46 is box-shaped, enclosing the first housing 16. A recess 51 is formed in the opposing wall 49 of the second housing 46, which faces the second circuit board 40. The recess 51 exposes the second mounting portion 65, the connection part of the second circuit board connector 62 that connects to the second circuit board 40, to the outside of the second housing 46. With this structure, by forming the recess 51, the connection state of the second circuit board connector 62 and the second circuit board 40 can be visually confirmed from the left, right, or rear sides of the second housing 46.

[0041] The second terminal part 55 approaches and engages with the first terminal part 25 in a direction intersecting with the first circuit board 10. The second circuit board connection portion 62 is surface-mounted to the second circuit board 40. The second mounting portion 65 of the second circuit board connection portion 62 has an extension portion 66 that protrudes towards the side (rear) of the first circuit board 10 from the second terminal connection portion 56. With this structure, in the engagement direction (front-back direction) of the first terminal connection portion 26 relative to the second terminal connection portion 56, the engagement length of the second circuit board connection portion 62 relative to the second circuit board 40 can be ensured to be relatively long. Thus, when the first terminal connection portion 26 and the second terminal connection portion 56 are connected, even if a front-back pressing force is applied to the second terminal part 55 from the first terminal part 25 (elastic contact piece 28), the second terminal part 55 can be reliably fixed to the second circuit board 40 in advance. The extension portion 66 extends towards the side of the first circuit board 10, but the rear end of the extension portion 66 is located forward of the rear end of the second housing 46. Therefore, due to the formation of the extension 66, the second connector 45 will not be enlarged in the front-rear direction.

[0042] A pair of first terminal parts 25 are arranged in a direction parallel to the first circuit board 10, i.e., in a left-right direction. The first circuit board connection portion 30 has a first bend portion 32 and a first mounting portion 33. The first bend portion 32 is in the shape of a quarter circle and extends from the first terminal connection portion 26 via the first plate-like base portion 31. The first mounting portion 33 extends from the first bend portion 32 parallel to the first circuit board 10. The extending directions of the pair of first mounting portions 33 are opposite to each other in the arrangement direction (left-right direction) of the pair of first terminal parts 25. According to this structure, a longer creepage distance between the pair of first mounting portions 33 can be ensured on the first mounting surface 11 of the first circuit board 10.

[0043] A pair of second terminal parts 55 are arranged in a direction parallel to the second circuit board 40, i.e., in a left-right direction. The second circuit board connection portion 62 has a second bend portion 64 and a second mounting portion 65. The second bend portion 64 is in the shape of a quarter circle and extends from the second terminal connection portion 56 via the second plate-shaped base portion 63. The second mounting portion 65 extends from the second bend portion 64 parallel to the second circuit board 40. The extending directions of the pair of second mounting portions 65 are opposite to each other in the arrangement direction (left-right direction) of the pair of second terminal parts 55. According to this structure, a longer creepage distance between the pair of second mounting portions 65 can be ensured on the second mounting surface 41 of the second circuit board 40.

[0044] The second terminal component 55 is assembled with the second terminal connector 56 pressed into the second housing 46. The second terminal connector 56 has two plate-shaped portions 58L and 58R bent into a folded-back shape. A second circuit board connector 62 is connected to one of the two plate-shaped portions 58L and 58R. A pressure-receiving surface 60 is formed on the end face of the other plate-shaped portion 58L and 58R, and a pressing force is applied to the pressure-receiving surface 60 to press the second terminal component 55 into the second housing 46. According to this structure, by making the second terminal connector 56 folded back, the strength of the second terminal connector 56 can be improved. In addition, by making the second terminal connector 56 folded back, the pressure-receiving surface 60 that receives the pressing force during insertion is ensured in the second terminal connector 56, so that no pressing force is applied to the second circuit board connector 62. Therefore, the second terminal part 55 can be pressed into the second housing 46 without deforming or damaging the second circuit board connection part 62.

[0045] [Other Embodiments] This invention is not limited to the embodiments described above and illustrated in the drawings, but is shown by the claims. The invention includes all modifications within the meaning and scope of the claims, and also includes the following embodiments. Alternatively, the first terminal component can be set as a male terminal, and the second terminal component can be set as a female terminal. The second housing can also be a shape without supporting walls. The second circuit board connector and the second circuit board connector can also be housed inside the second housing and cannot be seen from the outside. In the mating direction (orthogonal to the first circuit board) of the first terminal connection portion and the second terminal connection portion, the second circuit board connection portion and the second terminal connection portion may also be of the same size. The second terminal component can also be assembled to the second housing by means other than press-fitting. Explanation of reference numerals in the attached figures
