The cross-sectional shape of the elastic portion, orthogonal to the length direction, is approximately square, thereby enabling smooth displacement of the inner housing in the front-back and left-right directions. However, to allow a larger current to flow to the terminal, it is necessary to increase the cross-sectional area of the elastic portion orthogonal to the length direction. But increasing this area makes elastic deformation difficult, raising concerns that it may hinder the displacement of the inner housing in the front-back and left-right directions.

[0010] [Description of embodiments of this disclosure] First, embodiments of this disclosure will be described. (1) A terminal component, comprising: The terminal connection part connects to the terminal on the other side; The substrate connection part is connected to the circuit board; and A displacement-allowing portion is disposed between the terminal connection portion and the substrate connection portion, allowing relative displacement between the substrate connection portion and the terminal connection portion. The displacement-allowing portion includes a first plate portion and a second plate portion that are strip-shaped and extend in the front-rear direction. The rear end of the first plate is connected to the terminal connection portion. The rear end of the second plate is connected to the substrate connection portion. The front ends of the first plate and the second plate are connected to each other. The thickness direction of the first plate is the direction that intersects with the thickness direction of the second plate.
[0011] Since the thickness direction of the first plate portion in the terminal component (1) intersects with the thickness direction of the second plate portion, the relative displacement between the substrate connection portion and the terminal connection portion can be freed by the displacement allowance portion. In addition, since the first plate portion and the second plate portion are strip-shaped, the thickness in the flexural direction can be kept constant, and the cross-sectional area orthogonal to the length direction can be increased, thereby enabling the flow of a larger current. Here, strip-shaped refers to a long and thin plate-shaped state.
[0012] (2) In the terminal component described in (1), the terminal connection portion is in the shape of a square tube extending in the front-rear direction. The terminal component has a rigid portion that is L-shaped and connected to adjacent first and second wall portions forming the terminal connection portion, and extends rearward. When viewed from the front, the rigid portion and the first plate portion are positioned within the outline of the terminal connection portion.
[0013] (2) The terminal part can be configured such that when viewed from the front or rear, the rigid part and the first plate part do not protrude from the terminal connection part, thereby making it easy to reduce the size of the terminal part.
[0014] (3) In the terminal part described in (2), in the unfolded state, the rigid part, the first plate part and the second plate part are connected in a manner that folds back in the front-rear direction.
[0015] (3) The terminal parts can compact the arrangement of the rigid part, the first plate part and the second plate part in the unfolded state to a smaller extent, thereby making it easy to reduce the area of the base material such as strip steel.
[0016] (4) In the terminal part described in (2) or (3), a gripping part is provided connectedly at the rear end of the rigid part.
[0017] (4) The terminal parts are provided with a gripping part, which allows the terminal parts to be operated without contacting the first plate and the second plate.
[0018] (5) A connector comprising: The terminal part as described in any one of (1) to (4); The inner housing has multiple chambers for accommodating the terminal connections; and The outer casing is used for connecting the substrate connection portion.
[0019] (5) The connector allows the inner housing to float and enables the flow of a larger current.
[0020] [Details of the embodiments of this disclosure] <Implementation Method 1> In embodiment 1, connector 100 is mounted on one mounting surface of circuit board S and engages with connector P on the other side, which is mounted on the mounting surface of a circuit board (not shown) that is independently disposed from circuit board S. Figure 1 As shown, the connector 100 includes multiple terminal parts 11, an inner housing 91, an outer housing 92, and a pair of posts 93. The terminal parts 11 and posts 93 are formed by stamping a conductive metal plate. The inner housing 91 and the outer housing 92 are made of synthetic resin. In this embodiment 1, in the drawings, "front side," "rear side," "upper side," "lower side," "right side," and "left side" are represented by "F," "B," "U," "D," "R," and "L," respectively. Furthermore, the front-rear direction is the direction in which the connector 100 engages with the counterpart connector P.
[0021] [Structure of terminal components] Multiple terminal parts 11 have the same shape. For example... Figure 2 , Figure 3 As shown, the terminal component 11 includes a terminal connection portion 11A, a rigid portion 11B extending rearward in an L-shape from the rear end of the terminal connection portion 11A, a gripping portion 11C connected to the rear end of the rigid portion 11B, a displacement allowing portion 11D, and a substrate connection portion 11E. The terminal connection portion 11A is a rectangular tube extending in the front-rear direction and open on both sides in the front-rear direction. The terminal connection portion 11A is formed into a rectangular tube shape by a first wall portion 11F, a second wall portion 11G, a third wall portion 11H, and a fourth wall portion 11J. The first wall portion 11F is disposed on the lower side. The second wall portion 11G is disposed on the left side and its lower edge is connected to the first wall portion 11F (see reference). Figure 3 The third wall portion 11H is positioned on the upper side, with its left edge connected to the second wall portion 11G. The fourth wall portion 11J is positioned on the right side, with its upper edge connected to the third wall portion 11H and its lower edge connected to the first wall portion 11F (see reference). Figure 2 A locking part 11S protruding upward is provided in the third wall part 11H.
[0022] An elastic contact piece 11T is provided inside the terminal connection portion 11A (see reference). Figure 4 The elastic contact piece 11T is connected to the opposite terminal T (protrusion) (see reference). Figure 8 The tab is inserted into the interior of the terminal connection portion 11A from the front, and contacts the elastic contact piece 11T to connect with the terminal connection portion 11A.
[0023] The rigid portion 11B is formed in an L-shape and extends rearward, coplanarly connected to the first wall portion 11F and the second wall portion 11G in the wall portion forming the terminal connection portion 11A (see reference). Figure 3 Specifically, the rigid portion 11B has a first rigid portion 11U that is coplanarly connected to the first wall portion 11F in such a way that the thickness direction is vertical, and a second rigid portion 11V that is coplanarly connected to the second wall portion 11G in such a way that the thickness direction is horizontal. The long sides of the first rigid portion 11U and the second rigid portion 11V are connected to each other in an L-shape. As a result, the rigid portion 11B is difficult to deform and can maintain its shape.
[0024] The gripping portion 11C is configured to connect to and extend rearward from the rear end of the first rigid portion 11U of the rigid portion 11B. In other words, the gripping portion 11C is located behind the terminal connection portion 11A. The gripping portion 11C is configured to be coplanar with the first rigid portion 11U of the rigid portion 11B and the first wall portion 11F of the terminal connection portion 11A (see reference). Figure 3 The grip portion 11C extends rearward in a cantilever shape. In other words, no parts are disposed behind the grip portion 11C. Therefore, the grip portion 11C is a part that can be gripped from the rear.
[0025] The displacement-allowing part 11D includes a first plate portion 11K and a second plate portion 11L that extend in the front-rear direction and are elastically deformable. The displacement-allowing part 11D and the gripping part 11C are different parts from each other. The first plate portion 11K and the second plate portion 11L are strip-shaped. The first plate portion 11K and the second plate portion 11L overlap with the rigid part 11B in the front-rear direction. Specifically, the first plate portion 11K is arranged at an open interval behind the fourth wall portion 11J (see reference). Figure 2 The thickness direction of the first plate portion 11K faces left to right. The second plate portion 11L is arranged in a spaced-out manner behind the third wall portion 11H (see reference). Figure 2The thickness direction of the second plate portion 11L is oriented vertically. That is, the thickness direction of the first plate portion 11K is orthogonal to the thickness direction of the second plate portion 11L. The first plate portion 11K can elastically deform in its thickness direction (left-right direction), but not in the direction orthogonal to the thickness direction (vertical direction). The second plate portion 11L can elastically deform in its thickness direction (vertical direction), but not in the direction orthogonal to the thickness direction (left-right direction).
[0026] The rear end of the first plate portion 11K is connected to the rear end of the rigid portion 11B, which is connected to the first wall portion 11F, at a right angle in the thickness direction. That is, the rear end of the first plate portion 11K is connected to the rigid portion 11B, which is connected to the terminal connection portion 11A (i.e., electrically connected to the terminal connection portion 11A). The front ends of the first plate portion 11K and the second plate portion 11L are perpendicular to each other in the thickness direction. The front ends of the first plate portion 11K and the second plate portion 11L are connected to each other at a position forward of their rear ends. The second plate portion 11L tilts upwards (away from the rigid portion 11B) towards the rear end.
[0027] The substrate connecting portion 11E includes a pressing portion 11M and a connecting body portion 11N. The pressing portion 11M is strip-shaped and extends in the front-to-back direction with the thickness direction of the substrate pointing vertically. Multiple pressing blades 11P are provided at the left and right end edges of the pressing portion 11M, protruding in the left-to-right direction. A pair of rectangular portions 11Q protruding in a cuboid shape in the left-to-right direction are provided at the rear end of the pressing portion 11M. The connecting body portion 11N is connected to the rear end of the substrate connecting portion 11E and extends upwardly in a bent manner.
[0028] The front end of the press-in portion 11M is connected to the rear end of the second plate portion 11L of the displacement allowable portion 11D via the connecting plate portion 11R. In other words, the rear end of the second plate portion 11L is connected to the press-in portion 11M of the substrate connection portion 11E via the connecting plate portion 11R. That is, the rear end of the second plate portion 11L is electrically connected to the substrate connection portion 11E side. In other words, the displacement allowable portion 11D is provided between the terminal connection portion 11A and the substrate connection portion 11E. The connecting plate portion 11R extends vertically in such a way that the thickness direction is oriented in the front-rear direction. In the frontal view, the rigid portion 11B and the first plate portion 11K are arranged within the outline of the terminal connection portion 11A (see reference). Figure 4 This forms terminal component 11.
[0029] like Figure 5 As shown, in the unfolded state of the terminal part 11 ( Figure 5On the left side of the image, the rigid part 11B, the first plate part 11K, and the second plate part 11L are connected in a manner that folds back in the front-rear direction. (After the bending process is completed) Figure 5 The terminal part 11 (right side) is conveyed with the gripping part 11C connected to the carrier Ca. Specifically, the gripping part 11C is bent so that it forms a right angle with respect to the carrier Ca, and the posture of the terminal part 11 is adjusted so that the rigid part 11B and the substrate connecting part 11E are arranged in the direction of expansion of the plate surface of the carrier Ca.
[0030] [Structure of the inner shell] like Figure 6 As shown, the inner shell 91 has a block-shaped shell body 91A, a partition wall 91B extending downward from the shell body 91A, and a pair of protrusions 91C extending outward in a left-right direction from the lower end of the partition wall 91B. Multiple chambers 91D are formed through the shell body 91A in a front-rear direction. The multiple chambers 91D are arranged in a left-right direction and form two rows vertically. A spear-shaped member 91E is provided in each chamber 91D (see reference). Figure 9 ).
[0031] The partition wall 91B is provided protruding downwards from the main body of the housing 91A such that the thickness direction is oriented vertically. The partition wall 91B is connected to the lower end of the wall that separates the chambers 91D arranged vertically in two rows (see reference). Figure 9 At both ends of the partition wall 91B in the left and right directions, there are left and right partition walls 91G that extend downward from both ends of the housing body 91A in the left and right directions so that the thickness direction is in the left and right directions.
[0032] A pair of protrusions 91C are provided to extend outward in the left-right direction from the partition wall 91G of the partition wall 91B. At the protruding end in the left-right direction of each protrusion 91C, a protrusion 91F is provided so as to protrude in the vertical direction. This forms the inner housing 91.
[0033] [Structure of the outer shell] like Figure 7 As shown, the outer casing 92 is a quadrilateral ring. The outer casing 92 has a pair of upper and lower retaining wall portions 92A extending in the left-right direction and a pair of left and right covering portions 92B disposed on both sides in the left-right direction and connecting the upper and lower retaining wall portions 92A. Multiple grooves 92C are formed in a left-right arrangement on the upper and lower retaining wall portions 92A. Each groove 92C opens inward and rearward in the up-down direction.
[0034] A pair of left and right covers 92B form a storage space C inside. The storage space C opens inward and downward in the left and right directions. At the outer ends of each cover 92B in the left and right directions, a mounting recess 92D is formed that is recessed inward in the left and right directions. The outer shell 92 has an opening 92E surrounded by a pair of upper and lower retaining wall portions 92A and a pair of left and right covers 92B. In this way, the outer shell 92 is formed.
[0035] [Structure of a bolt pile] like Figure 1 As shown, a pair of studs 93 are arranged such that the plate thickness direction is oriented to the left and right. The lower end of each stud 93 is folded back outward in the left and right direction. At the front and rear edges of the upper part of each stud 93, a plurality of locking protrusions 93A protruding in the front-rear direction are provided.
[0036] [An example of a connector assembly method] Next, an example of the assembly method for connector 100 will be described. Figure 8 , Figure 9 As shown, firstly, the terminal parts 11 are installed from the rear into each chamber 91D of the inner housing 91. For example, the terminal connection part 11A is inserted from the rear into the chamber 91D by holding the gripping part 11C from the rear using a clamp (not shown). At this time, in the upper chamber 91D, the position of the terminal parts 11 is adjusted so that the substrate connection part 11E protrudes upwards (see reference). Figure 9 Then, within the lower chamber 91D, the position of the terminal component 11 is adjusted so that the substrate connection portion 11E protrudes downwards (see reference). Figure 9 In this way, the terminal connector 11A is inserted into each chamber 91D by adjusting the posture of the terminal component 11. When the terminal connector 11A reaches the correct position within the chamber 91D, the locking part 11S moves forward past the spear-shaped member 91E and locks into the spear-shaped member 91E (see reference). Figure 9 Therefore, the terminal part 11 will not detach from the cavity 91D. In this way, the terminal connection part 11A is housed in the cavity 91D, thereby mounting the terminal part 11 on the inner housing 91.
[0037] Next, the press-in portion 11M of the terminal part 11 is installed from the rear into each slot 92C of the outer housing 92. First, the housing body 91A of the inner housing 91, on which the terminal part 11 is installed, is inserted from below into the opening 92E. Then, each press-in portion 11M is pressed into each slot 92C from the rear (see reference). Figure 9 At this time, using a clamp (not shown), the pair of rectangular portions 11Q of each pressing portion 11M are pressed from the rear (see reference). Figure 8Press down. In this way, the substrate connection portion 11E is connected to the outer housing 92 by pressing each pressing portion 11M into each groove portion 92C. At this time, each protrusion 91F of the inner housing 91 is housed in the housing space C of the covering portion 92B formed in the outer housing 92.
[0038] Next, the stud 93 is installed from above into the mounting recess 92D formed in the outer housing 92 (see reference). Figure 8 This completes connector 100. In connector 100, the inner housing 91 and the outer housing 92 are connected via terminal parts 11, rather than in direct contact.
[0039] [The function of connectors] In a connector 100 formed in this way, the main body 11N is connected to each electrode provided on one of the mounting surfaces of the circuit board S by solder (see reference). Figure 9 ).like Figure 8 As shown, the counterpart connector P is engaged with the connector 100 to connect the counterpart terminal T to the terminal connection portion 11A. At this time, if the counterpart connector P is offset relative to the connector 100 in the left-right or up-down direction, the inner housing 91 is displaced relative to the outer housing 92 in a manner that follows the offset of the counterpart connector P.
[0040] For example, if the connector P on the other side is offset in the left-right direction, such as Figure 10 As shown, the inner housing 91 is displaced in the left-right direction relative to the outer housing 92. At this time, the first plate portion 11K of the terminal part 11 elastically deforms, thereby displacing the inner housing 91 in the left-right direction relative to the outer housing 92.
[0041] For example, if the connector P on the other side is offset in the vertical direction, such as Figure 11 As shown, the inner housing 91 is displaced vertically relative to the outer housing 92. At this time, the second plate portion 11L of the terminal part 11 elastically deforms, thereby displacing the inner housing 91 vertically relative to the outer housing 92. This allows the displacement-allowing portion 11D to allow relative displacement between the substrate connection portion 11E and the terminal connection portion 11A. The outer shape of the terminal connection portion 11A is slightly smaller than the inner shape of the cavity 91D. Therefore, when the inner housing 91 is displaced horizontally or vertically relative to the outer housing 92, the terminal connection portion 11A can be slightly tilted relative to the cavity 91D. This allows for easy and flexible connection to the counterpart terminal T of the counterpart connector P.
[0042] Next, we will illustrate the effect of this structure with an example. Terminal component 11 includes: a terminal connecting portion 11A, which connects to a counterpart terminal T; a substrate connecting portion 11E, which connects to a circuit board S; and a displacement allowing portion 11D, disposed between the terminal connecting portion 11A and the substrate connecting portion 11E, allowing relative displacement between the substrate connecting portion 11E and the terminal connecting portion 11A. The displacement allowing portion 11D includes a strip-shaped first plate portion 11K and a second plate portion 11L extending in a front-rear direction. The rear end of the first plate portion 11K is electrically connected to the terminal connecting portion 11A, and the rear end of the second plate portion 11L is electrically connected to the substrate connecting portion 11E. The front ends of the first plate portion 11K and the second plate portion 11L are connected to each other. The thickness direction of the first plate portion 11K is orthogonal to the thickness direction of the second plate portion 11L.
[0043] According to this structure, since the thickness direction of the first plate portion 11K is orthogonal to the thickness direction of the second plate portion 11L, the relative displacement between the substrate connection portion 11E and the terminal connection portion 11A can be freed by the displacement allowance portion 11D. In addition, since the first plate portion 11K and the second plate portion 11L are strip-shaped, the thickness in the bending direction can be kept constant while the cross-sectional area orthogonal to the length direction can be increased, thereby enabling the flow of a larger current.
[0044] The terminal connection portion 11A is a rectangular tube extending in the front-to-back direction. The terminal part 11 has a rigid portion 11B, which is L-shaped and connected to adjacent first wall portions 11F and second wall portions 11G in the wall portions forming the terminal connection portion 11A, and extends rearward. In the front view, the rigid portion 11B and the first plate portion 11K are arranged within the outline of the terminal connection portion 11A. According to this structure, when viewed from the front or rear, the rigid portion 11B and the first plate portion 11K can be arranged not to protrude from the terminal connection portion 11A, thereby easily reducing the size of the terminal part 11.
[0045] In the unfolded state, the rigid part 11B, the first plate part 11K, and the second plate part 11L are connected in a manner that folds back in the front-rear direction. According to this structure, the arrangement of the rigid part 11B, the first plate part 11K, and the second plate part 11L in the unfolded state can be made compact to a smaller extent, thereby easily reducing the area of the base material such as strip steel.
[0046] At the rear end of the rigid part 11B, a gripping part 11C is provided for holding. According to this structure, by providing the gripping part 11C, the terminal part 11 can be operated without contacting the first plate part 11K and the second plate part 11L.
[0047] The connector 100 includes a terminal component 11, an inner housing 91 having a cavity 91D that houses multiple terminal connection portions 11A, and an outer housing 92 for connection to a substrate connection portion 11E. This structure allows the inner housing 91 to float and enables the flow of a larger current.
[0048] <Implementation Method 2> The connector 200 in Embodiment 2 differs from that in Embodiment 1 in that: the substrate connection portion 111E of the terminal part 111 is inserted into the through hole H formed in the circuit board S; and the chambers 191D formed in the inner housing 191 are arranged in three rows vertically. The same reference numerals are used for the same structures as in Embodiment 1, and repeated descriptions are omitted.
[0049] like Figure 12 As shown, connector 200 includes multiple terminal parts 111, an inner housing 191, an outer housing 192, and a pair of studs 193.
[0050] [Structure of terminal components] like Figure 13 As shown, the terminal component 111 includes a terminal connection portion 11A, a third plate portion 111B, a displacement allowance portion 111D, and a substrate connection portion 111E. The third plate portion 111B is formed to connect to the first wall portion 11F of the terminal connection portion 11A and extends rearward in a strip shape. The displacement allowance portion 111D has a first plate portion 111K and a second plate portion 111L that extend in the front-rear direction and are elastically deformable. The first plate portion 111K and the second plate portion 111L are strip-shaped. The thickness direction of the first plate portion 111K is oriented in the left-right direction. The thickness direction of the second plate portion 111L is oriented in the up-down direction. The first plate portion 111K and the second plate portion 111L are elastically deformable in their respective thickness directions.
[0051] The rear end of the first plate portion 111K is connected to the rear end of the third plate portion 111B at a right angle in the thickness direction. The front ends of the first plate portion 111K and the second plate portion 111L are connected to each other at a right angle in the thickness direction. The second plate portion 111L extends further rearward than the rear ends of the first plate portion 111K and the third plate portion 111B.
[0052] The substrate connecting portion 111E has a pressing portion 111M and a connecting body portion 111N. The pressing portion 111M and the connecting body portion 111N are strip-shaped and extend together in the front-to-back direction with the thickness direction facing up and down. A pair of rectangular portions 111Q protruding in the left-to-right direction are provided in the pressing portion 111M. The front end of the pressing portion 111M is connected to the rear end of the second plate portion 111L of the displacement allowing portion 111D via a connecting plate portion 111R. The connecting plate portion 111R extends in the up-to-down direction with the thickness direction facing up and down.
[0053] [Structure of the inner shell] like Figure 12 As shown, the inner shell 191 has a block-shaped shell body 191A and a pair of elastic walls 191B extending downward from the shell body 191A. Multiple chambers 191D are formed through the shell body 191A in the front-rear direction. The multiple chambers 191D are arranged in the left-right direction and form three rows vertically. A spear-shaped member (not shown) is provided in each chamber 191D.
[0054] A pair of elastic walls 191B are connected to the upper and lower walls of the housing body 191A and extend downward in such a way that the thickness direction is oriented vertically. Each elastic wall 191B has two through-holes 191H formed in the thickness direction.
[0055] [Structure of the outer shell] like Figure 14 As shown, the outer shell 192 is block-shaped. The outer shell 192 has multiple through holes 192F extending in the front-rear direction. The multiple through holes 192F are arranged in the left-right direction and form three rows vertically. These through holes 192F correspond to the chambers 191D of the inner shell 191. A groove 192C is formed at the rear end of each through hole 192F. The grooves 192C of the through holes 192F in the uppermost, centrally located row in the vertical direction face downwards and open rearwards. The grooves 192C of the through holes 192F in the lowermost row face upwards and open rearwards. The outer shell 192 has multiple locking claws 192G, protruding edges 192H, and a pair of fixing portions 192J. The multiple locking claws 192G are protruding from the upper and lower surfaces of the front portion of the outer shell 192. Figure 14 The locking claw 192G located on the lower surface of the outer housing 192 is not shown in the figure.
[0056] A protruding edge 192H extends from the rear of the outer housing 192 in both vertical and horizontal directions. A pair of fixing parts 192J protrude outward in the horizontal direction on both sides of the protruding edge 192H. Each fixing part 192J has a through hole 192K formed in a vertical direction.
[0057] [Structure of a bolt pile] like Figure 12 As shown, a pair of studs 193 are arranged such that the plate thickness direction is oriented to the left and right. Each stud 193 has a plurality of downwardly extending protrusions 193B arranged in a vertical direction.
[0058] [An example of a connector assembly method] Next, refer to Figure 15An example of the assembly method for connector 200 will be described. First, the press-in portion 111M of terminal part 111 is installed from the rear into each slot 192C of outer housing 192. At this time, first, the terminal connection portion 11A of terminal part 111 is inserted from below into the communicating hole 192F. Then, each press-in portion 111M is pressed into each slot 192C from the rear. After pressing each press-in portion 111M into each slot 192C, the terminal connection portion 11A protrudes forward of outer housing 192. In addition, the connecting body portion 111N protrudes rearward of outer housing 192.
[0059] Next, the inner housing 191 is installed onto the outer housing 192. Specifically, a pair of elastic walls 191B are brought close to the outer housing 192 from the front, causing the locking claws 192G to engage with the locking holes 191H. At the same time, the terminal connecting portions 11A, which protrude forward from the outer housing 192, are inserted into the chambers 191D from the rear. When the terminal connecting portions 11A reach their proper positions within the chambers 191D, the spear-shaped members (not shown) engage with the locking portions 11S.
[0060] Next, each stud 193 is installed from above into the insertion holes 192K formed in each fixing part 192J of the outer housing 192 (see reference). Figure 14 When the installation of each stud 193 is completed, each protrusion 193B protrudes behind the outer housing 192. This completes the connector 200.
[0061] Next, the connector 200, formed in this way, is mounted on the circuit board S. Specifically, the connecting body portion 111N and the protrusion 193B, which protrude to the rear of the outer housing 192, are inserted into the through hole H formed in the circuit board S, and connected to the electrodes provided on the mounting surface of the circuit board S by solder.
