Summary of Invention

Problems to be Solved by the Invention

[0004] In the above, if the positional deviation between the plug terminal and the receptacle contact portion increases, the receptacle contact portion tilts greatly, the plug terminal strongly contacts the root of one of the first contact piece and the second contact piece, and there is a possibility that the root of one of the contact pieces is plastically deformed. In addition, excessive stress is generated in the receptacle board connecting portion, and in the worst case, there is a concern that the solder formed between the receptacle board connecting portion and the board may peel off.

[0005] Therefore, the present disclosure aims to provide a terminal that exhibits good conformity to the mating terminal and is less prone to generating excessive stress. [Means for solving the problem]

[0006] The terminal of this disclosure comprises a main body that can assume an upright position, a board connection portion that is connected to a board, a support portion provided between the main body and the board connection portion to support the main body, and a pressing portion, wherein the main body has a contact portion that contacts a mating terminal and a pressed portion formed in the shape of a wall at a position different from the contact portion, and the pressing portion is provided at a position in which it can contact the pressed portion in the direction in which the main body falls from the upright position accompanied by the elastic deformation of the support portion. [Effects of the Invention]

[0007] According to this disclosure, it is possible to provide a terminal that has good conformability to the mating terminal and is less prone to excessive stress. [Brief explanation of the drawing]

[Figure 6] Figure 6 is a plan view of the terminal according to this embodiment 1.

[Modes for carrying out the invention]

[0009] [Description of Embodiments in this Disclosure] First, the embodiments of this disclosure will be listed and described. The terminals in this disclosure are (1) The device comprises a main body that can assume an upright position, a board connection part connected to a circuit board, a support part provided between the main body and the board connection part to support the main body, and a pressing part, wherein the main body has a contact part that contacts a mating terminal and a pressed part formed in the shape of a wall at a different position from the contact part, and the pressing part is provided at a position in which it can contact the pressed part in the direction in which the main body falls from the upright position accompanied by the elastic deformation of the support part.

[0010] When the connection between the main body and the mating terminal is initiated, if the mating terminal is misaligned relative to the main body, the main body can fall from its upright position due to the elastic deformation of the support portion. At this time, if the amount of misalignment (floating amount) between the main body and the mating terminal exceeds the allowable amount, the pressed portion of the main body comes into contact with the pressing portion, preventing the main body from falling any further. Therefore, excessive stress can be prevented from occurring in the contact portion that comes into contact with the mating terminal and in the board connection portion connected to the support portion, thereby ensuring the connection stability of the terminal to both the mating terminal and the board.

[0011] (2) In the terminal described in (1) above, when the main body falls from the upright position in both directions of the first direction due to the elastic deformation of the plate-shaped support, it is preferable that the pressed portion and the pressing portion are provided corresponding to both directions of the first direction, respectively. According to the configuration in (2) above, it is possible to prevent the main body from falling over beyond the permissible range in any direction of the first direction.

[0012] (3) In the terminal described in (2) above, when the main body falls from the upright position in both directions of the first direction and the second direction perpendicular to it, accompanied by elastic deformation of the plate-shaped support, it is preferable that the pressed portion and the pressing portion are provided corresponding to both directions of the second direction, respectively. According to the configuration described in (3) above, it is possible to prevent the main body from tilting beyond the permissible range in both directions of the first direction of the support, as well as in any direction of the second direction.

[0013] (4) In the terminal described in (3) above, the board connection portion is provided in pairs spaced apart in the second direction, and preferably comprises a pair of rising portions rising from the pair of board connection portions, a bridge portion spanning between one end of the pair of rising portions in the first direction, and an extension portion extending from one of the other ends of the pair of rising portions in the first direction toward the other, wherein the pair of rising portions, the bridge portion, and the extension portion are arranged to surround the main body portion and each has the pressing portion. According to the configuration described in (4) above, the parts having each clamping portion (each rising portion, mounting portion, and extension portion) and each substrate connection portion can be integrally formed by bending a single sheet of material, making manufacturing easy and preventing an increase in the number of parts. In addition, since the pair of rising portions, mounting portions, and extension portions surround the main body, interference between the main body and external foreign objects can be prevented.

[0014] (5) In the terminal described in (4) above, the support portion is preferably provided to extend from the mounting portion and connect to the main body portion. According to the configuration described in (5) above, each rising section, extension section, mounting section, support section, and main body section can be formed integrally by bending a single sheet of material, making manufacturing easier and avoiding an increase in the number of parts.

[0015] (6) In the terminal described in any of (1) to (5) above, the main body is cylindrical, an insertion opening for receiving the mating terminal is provided at one end of the main body, a guide portion is provided at the edge of the insertion opening of the main body that widens toward the tip, and the guide portion is provided in a position where the main body can come into contact with the mating terminal when it is tilted from the upright position. According to the configuration of the above (6), when the main body portion and the mating terminal are about to exceed the mutually allowable positional deviation amount, the guiding portion can be brought into contact with the mating terminal, so that the connection work (fitting work) between the mating terminal and the main body portion can be smoothly performed.

[0016] [Details of the Embodiments of the Present Disclosure] Specific examples of the present disclosure will be described below with reference to the drawings. It should be noted that the present invention is not limited to this illustration, is indicated by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.

[0017] <Embodiment 1> As shown in Figure 1, Embodiment 1 of the present disclosure exemplifies a terminal 10 installed on one circuit board 70 among mutually opposing circuit boards 70 and 80. Two terminals 10 are arranged side by side on the one circuit board 70. The other circuit board 80 is provided with two mating terminals 90 corresponding to both terminals 10 and 90. The mating terminal 90 has a tab shape and protrudes toward the one circuit board 70. The terminal 10 includes a board connection portion 11 connected to the circuit board 70, a main body portion 12 connected to the mating terminal 90, and a support portion 13 disposed between the main body portion 12 and the board connection portion 11 to support the main body portion 12 in a floating state. The terminal 10 is formed of a single conductive metal plate material. Here, the terminal 10 is integrally formed by punching the plate material into the developed shape shown in Figure 2, and bending the resulting product along the one-dot chain line in Figure 2.

[0018] Both terminals 10 and 90 are not covered by a housing or the like, and are exposed on the mounting surface 71 of the circuit board 70. In Figures 1 and 3, the symbols X, Y, and Z represent the front-to-back, left-to-right, and up-and-down directions, respectively. The up-and-down direction is the direction in which the two circuit boards 70 and 80 face each other. For convenience, the top of Figure 1 is considered the top, the left side of Figure 1 is considered the front, and the direction towards the viewer in Figure 1 is considered the right. The front-to-back direction is sometimes referred to as both directions of the first direction. The front end is sometimes referred to as the other end of the first direction, and the rear end is sometimes referred to as one end of the first direction. The left-to-right direction is sometimes referred to as both directions of the second direction (directions perpendicular to the first direction). These directional references are for convenience only and do not necessarily coincide with the directional references when terminal 10 is installed on the circuit board 70 and mounted on a vehicle or the like.

[0019] As shown in Figures 3 and 6, the terminal 10 is equipped with a board connection portion 11 as described above. The board connection portion 11 has a rectangular shape that is elongated in the front-to-back direction when viewed from above, with its board surface facing up and down. The board connection portions 11 are provided in pairs, spaced apart in the left-to-right direction. Both board connection portions 11 are arranged along the mounting surface 71 of the circuit board 70 and are connected by soldering to a conductive portion (not shown) of the mounting surface 71.

[0020] As shown in Figure 3, the terminal 10 is provided with a pair of left and right rising parts 14 that rise from the left and right inward-facing ends of each of the two board connection parts 11. In side view, the rising parts 14 have a rectangular shape that is long in the vertical direction, with their surface facing left and right. The rising parts 14 and the board connection part 11 are connected in the front-to-back direction with the same plate width, and as shown in Figures 4 and 5, they form an L shape in front view.

[0021] The terminal 10 is equipped with a support section 15 that is integrally spanned between the upper rear ends of the double-mounted upper section 14. As shown in Figure 6, the support section 15 is composed of a pair of left and right protruding sections 16 that project slightly rearward from each of the double-mounted upper section 14, and a support body section 17 that extends long in the left-right direction between the rear ends of both protruding sections 16. The support section 15 has a gate shape in plan view. The upper end of the support section 15 and the upper end of the double-mounted upper section 14 are at the same height and connected without any steps. As shown in Figure 4, the support body section 17 has a rectangular outer shape that is long in the left-right direction in rear view, with its plate surface facing the front-rear direction.

[0022] The support portion 13 of the terminal 10 extends from the erection portion 15. As shown in Figures 1 and 4, the support portion 13 has a first extension portion 18 extending downward from the middle of the erection body portion 17 in the left-right direction, a second extension portion 19 extending briefly forward from the lower end of the first extension portion 18, and a third extension portion 21 extending briefly upward from the front end of the second extension portion 19. The first extension portion 18 and the third extension portion 21 have a rectangular outer shape that is long in the left-right direction when viewed from the rear and front, with the plate surface facing in the front-rear direction. The second extension portion 19 has a rectangular outer shape that is long in the left-right direction when viewed from the bottom, with the plate surface facing in the up-down direction. The first extension portion 18, the second extension portion 19, and the third extension portion 21 are connected in the left-right direction with the same plate width, and form a U shape when viewed from the side. The support portion 13 is elastically deformable in the front-rear direction. Furthermore, the support portion 13 is designed to be elastically deformable so as to twist in the left-right direction.

[0023] The main body 12 of the terminal 10 is always positioned in an upright position, with the upper end of the third extension 21 rising above it. As shown in Figures 3 and 6, the main body 12 is box-shaped, more specifically a flat rectangular tube that is elongated in the left-right direction relative to the front-rear direction, and has a first wall portion 22 and a second wall portion 23 facing each other in the front-rear direction, and a third wall portion 24 and a fourth wall portion 25 facing each other in the left-right direction. The first wall portion 22 and the second wall portion 23 have a rectangular outer shape that is elongated in the vertical direction when viewed from the rear and front, with the wall surface (plate surface) facing in the front-rear direction. The upper end of the third extension portion 21 is connected to the middle part in the left-right direction at the lower end of the first wall portion 22. The left third wall portion 24 is integrally spanned between the left ends of the first wall portion 22 and the second wall portion 23. The fourth wall portion 25 on the right extends from the right end of the first wall portion 22 to the right end of the second wall portion 23, and further has a portion that bends so that its extending end overlaps the front surface of the second wall portion 23 from its right end.

[0024] Multiple contact portions 26 are provided in the left-right direction on each of the first wall portion 22 and the second wall portion 23. Each contact portion 26 is formed by bending and raising a plate portion within a cut in each of the first wall portion 22 and the second wall portion 23. Each contact portion 26 extends upward from the middle of the vertical direction of each of the first wall portion 22 and the second wall portion 23. Each contact portion 26 is elastically deformable in the front-rear direction. The upper end of each contact portion 26 is bent inward in the left-right direction. As shown in Figures 1 and 6, an embossed contact portion 27 is provided as a bulge at the inward end in the left-right direction of each contact portion 26. The contact portions 27 of each contact portion 26 of the first wall portion 22 and the contact portions 27 of each contact portion 26 of the second wall portion 23 are arranged facing each other in the front-rear direction inside the main body portion 12. A mating terminal 90 is inserted between each of the front-rear facing contact portions 27 to make an electrical connection.

[0025] An insertion opening 28 for receiving the mating terminal 90 is provided at the upper end of the main body 12. As shown in Figure 6, the edge of the insertion opening 28 is bordered in a rectangular shape in plan view by the upper ends of the first to fourth wall sections 22, 23, 24, and 25. The main body 12 is provided with a plurality of guide sections 29 that expand upward from the upper ends of the first to fourth wall sections 22, 23, 24, and 25 (the edges of the insertion opening 28). Each guide section 29 consists of a front, rear, left, and right section. As shown in Figure 3, the front guide section 29 extends diagonally upward and forward from the upper end of the second wall section 23. The rear guide section 29 extends diagonally upward and backward from the upper end of the first wall section 22. In other words, the front and rear guide sections 29 expand so that they move away from each other in the front-rear direction as they extend upward. The left-hand guiding section 29 extends from the upper end of the third wall section 24, sloping diagonally upward and to the left. The right-hand guiding section 29 extends from the upper end of the fourth wall section 25, sloping diagonally upward and to the right. In other words, the left and right guiding sections 29 expand outwards from each other in the left-right direction as they extend upward. The front and rear guiding sections 29 are formed to be long in the left-right direction in the portions of the upper ends of the second wall section 23 and the third wall section 24, excluding both ends in the left-right direction. The left and right guiding sections 29 are formed to be short in the front-rear direction in the portions of the upper ends of the third wall section 24 and the fourth wall section 25, excluding both ends in the front-rear direction.

[0026] The terminal 10 is equipped with an attachment portion 31 that protrudes forward from the upper part of the front end of the right-hand rising portion 14 of the two rising portions 14. The attachment portion 31 has a rectangular outer shape when viewed from the side, with its plate surface oriented in the left-right direction.

[0027] As shown in Figures 3 and 5, the terminal 10 includes an extension 32 that extends to the right from the upper front end of the left of the two vertical upper parts 14. The extension 32 has a rectangular shape that is long in the left-right direction when viewed from the front, with its plate surface facing the front-back direction. The extension 32 is formed by bending a strip-shaped portion that extends forward from the upper front end of the vertical part 14 at a right angle to the right. The right end of the extension 32 is located in or near the center of the main body 12 in the left-right direction. The extension 32 is positioned to overlap with each contact part 26 in the vertical direction and is within the same height range as the attachment part 31.

[0028] As shown in Figure 6, the terminal 10 has forward, backward, left, and rightward pressing portions 33 spaced apart on its outer circumference. The terminal 10 also has forward, backward, left, and rightward pressing portions 34 on its main body 12, corresponding to the pressing portions 33.

[0029] The front retaining portion 33 is configured as an edge extending in the left-right direction at the upper rear edge of the extension portion 32. The rear retaining portion 33 is configured as an edge extending in the left-right direction at the upper front edge of the erection body portion 17. The left retaining portion 33 is configured as an edge extending in the front-rear direction at the upper right edge of the left rising portion 14. The right retaining portion 33 is configured as an edge extending in the front-rear direction at the upper left edge of the right rising portion 14. Each retaining portion 33 is positioned at the same height in the vertical direction.

[0030] The front pressing portion 34 is composed of the front wall portions located on both the left and right sides of the second wall portion 23, flanking each contact portion 26. The rear pressing portion 34 is composed of the rear wall portions located on both the left and right sides of the first wall portion 22, flanking each contact portion 26. The left pressing portion 34 is composed of the left wall portion of the third wall portion 24. The right pressing portion 34 is composed of the right wall portion of the fourth wall portion 25.

[0031] The structure of terminal 10 is as described above, and next, the manner in which terminal 10 is connected (mated) to the mating terminal 90 will be explained. Terminal 10 is installed on the mounting surface 71 of one circuit board 70 by soldering the two board connection portion 11. Similarly, the mating terminal 90 is installed on the mounting surface 71 of the other circuit board 80 by soldering. In this embodiment 1, one circuit board 70 is positioned below, and the other circuit board 80 is positioned above. Terminal 10 and the mating terminal 90 are positioned opposite each other in the vertical direction. In this state, both circuit boards 70 and 80 approach each other, and the mating terminal 90 is inserted into the main body portion 12 through the insertion opening 28. If terminal 10 and the mating terminal 90 are in a positional relationship where they face each other in the vertical direction, the mating terminal 90 is inserted between the contact portions 26 of the first wall portion 22 and the contact portions 26 of the second wall portion 23, making contact with the contact portions 27, and terminal 10 and the mating terminal 90 are electrically connected (see Figure 1).

[0032] In contrast, if, for example, the mating terminal 90 is misaligned forward from its direct position relative to terminal 10, and both circuit boards 70 and 80 approach each other, the lower end (tip) of the mating terminal 90 will come into contact with the front guiding portion 29, causing the main body 12 to tilt forward, accompanied by elastic deformation of the support portion 13. As shown in Figure 7, if the misalignment between terminal 10 and the mating terminal 90 is close to the limit that exceeds the allowable range, the lower end of the mating terminal 90 will come into contact with the front guiding portion 29 or the upper end of the inner surface of the second wall portion 23, and the front pressed portion 34 of the tilted main body 12 will abut against the front pressing portion 33 of the extension portion 32 from behind, suppressing further tilting of the main body 12. Furthermore, if the approaching movement of both circuit boards 70 and 80 continues, the lower end of the mating terminal 90 will slide downward against the inner surface of the second wall portion 23, and the misalignment between terminal 10 and the mating terminal 90 will be gradually corrected. Then, with the misalignment between terminal 10 and the mating terminal 90 almost corrected, the mating terminal 90 is inserted between the contact portions 26 of the first wall portion 22 and the contact portions 26 of the second wall portion 23. When both circuit boards 70 and 80 reach a position where they face each other at a predetermined distance, terminal 10 and the mating terminal 90 are connected in the normal state shown in Figure 1, and the connection work is completed.

[0033] Furthermore, if the mating terminal 90 is misaligned backward from its direct position relative to terminal 10 to near the limit of the allowable range, the lower end of the mating terminal 90 will come into contact with the rearward guide portion 29, and the rearward pressed portion 34 will abut against the rearward pressing portion 33 from the front. In addition, if the mating terminal 90 is misaligned to the left or right from its direct position relative to terminal 10 to near the limit of the allowable range, the lower end of the mating terminal 90 will come into contact with the left or rightward guide portion 29, and the left or rightward pressed portion 34 will abut against the left or rightward pressing portion 33, respectively. Thus, according to this embodiment 1, it is possible to avoid misalignment between terminal 10 and mating terminal 90 beyond the allowable range, and to prevent excessive stress from being generated in terminal 10 when connecting terminal 10 and mating terminal 90.

[0034] As described above, the terminal 10 of this embodiment 1 comprises a main body portion 12 that can assume an upright position, a substrate connection portion 11 that is connected to a substrate, a support portion 13 provided between the main body portion 12 and the substrate connection portion 11 to support the main body portion 12, and a pressing portion 33. The main body portion 12 has a contact portion 26 that contacts the mating terminal 90, and a pressed portion 34 formed in a wall shape at a different position from the contact portion 26. The pressing portion 33 is provided in a position where it can contact the pressed portion 34 in the direction in which the main body portion 12 falls from an upright position accompanied by the elastic deformation of the support portion 13.

[0035] When the connection between the main body 12 and the mating terminal 90 is initiated, if the mating terminal 90 is misaligned relative to the main body 12, the main body 12 can fall from its upright position due to the elastic deformation of the support portion 13. At this time, if the main body 12 and the mating terminal 90 attempt to exceed the allowable amount of misalignment (floating amount), the pressed portion 34 of the main body 12 comes into contact with the pressing portion 33, suppressing further collapse of the main body 12. As a result, the terminal 10 follows the mating terminal 90 well, preventing the terminal 10 and the mating terminal 90 from misaligning beyond the allowable range, and preventing excessive stress on the terminal 10. Consequently, the connection stability of the terminal 10 to both the mating terminal 90 and the substrate can be ensured.

[0036] Furthermore, in this embodiment 1, when the main body 12 falls from an upright position in both directions of the first direction (front-to-back direction) accompanied by the elastic deformation of the plate-shaped support portion 13, the restrained portion 34 and the restraining portion 33 are provided corresponding to both directions of the first direction, respectively. Therefore, it is possible to prevent the main body 12 from falling beyond the permissible range in either direction of the first direction.

[0037] Furthermore, in this embodiment 1, when the main body 12 tilts from an upright position in both directions (left and right) perpendicular to the first direction due to the elastic deformation of the plate-shaped support portion 13, the restrained portion 34 and the restraining portion 33 are provided corresponding to both directions in the second direction, respectively. Therefore, it is possible to prevent the main body 12 from tilting beyond the permissible range in both directions of the first direction of the support portion 13, as well as in either direction of the second direction.

[0038] In this embodiment 1, the board connection portions 11 are provided in pairs with a gap between them in the second direction. The terminal 10 comprises a pair of rising portions 14 rising from the pair of board connection portions 11, a bridge portion 15 spanning between one end (rear end) of the pair of rising portions 14 in the first direction, and an extension portion 32 extending from one (left) to the other (right) end (front end) of the pair of rising portions 14 in the first direction. The pair of rising portions 14, the bridge portion 15, and the extension portion 32 are arranged to surround the main body portion 12 and each has a retaining portion 33. With this, the portions having each retaining portion 33 (each rising portion 14, bridge portion 15, and extension portion 32) and each board connection portion 11 can be integrally formed by bending a single sheet of material, making manufacturing easy and preventing an increase in the number of parts. Furthermore, the pair of rising sections 14, the erection section 15, and the extension section 32 surround the main body 12, preventing the main body 12 from interfering with external foreign objects.

[0039] In particular, since the support section 13 is provided to extend from the erection section 15 and connect to the main body section 12, each of the rising sections 14, extension section 32, erection section 15, support section 13, and main body section 12 can be integrally formed by bending a single sheet of material, making manufacturing easier and avoiding an increase in the number of parts.

[0040] Furthermore, in this embodiment 1, the main body 12 is cylindrical. An insertion opening 28 for receiving the mating terminal 90 is provided at one end of the main body 12. A guide portion 29 that widens towards the tip is provided at the edge of the insertion opening 28 of the main body 12. The guide portion 29 is positioned so that it can contact the mating terminal 90 when the main body 12 is tilted from an upright position. Therefore, when the main body 12 and the mating terminal 90 are about to exceed a mutually permissible misalignment amount, the guide portion 29 can come into contact with the mating terminal 90, thus enabling smooth connection (fitting) between the mating terminal 90 and the main body 12.

[0041] [Other embodiments of this disclosure] Embodiment 1 disclosed herein should be considered in all respects to be illustrative and not restrictive. In the first embodiment described above, the main body was cylindrical and composed of first to fourth wall sections. In contrast, according to the other embodiment, the main body is composed of at least one of the first to fourth wall sections, and it is sufficient that a pressing portion is provided in one of the wall sections. In the first embodiment described above, the board connection portion was a surface-mount type connected along the mounting surface of the circuit board. In contrast, according to other embodiments, the board connection portion may be a through-hole type inserted into a through-hole of the circuit board and soldered. In the first embodiment described above, the extension extends from one (left) rising section toward the other (right) rising section, and its tip in the direction of extension (right end) is located at or near the center of the main body in the second direction (left-right direction). In contrast, according to other embodiments, the tip in the direction of extension may reach a position where it contacts the attached section or the other rising section. In short, the extension may span between both rising sections. [Explanation of Symbols]
