[0009] Embodiments of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited by these embodiments. Furthermore, some of the components in the following embodiments may be easily substituted or substantially identical to those that are easily substituted by those skilled in the art.

[0010] [Embodiment] This embodiment relates to a coupler device. Figure 1 is an exploded perspective view of the coupler device according to the embodiment, and Figure 2 is a vertical cross-sectional view of the coupler device when connected. Figures 3 and 4 are cross-sectional views taken along line III-III in Figure 1, and are explanatory diagrams of the connection in the coupler device according to the embodiment.

[0011] In the following explanation, of the three intersecting directions, the first direction will be referred to as the "connection direction X," the second direction as the "width direction Y," and the third direction as the "height direction Z." Here, the connection direction X, the width direction Y, and the height direction Z are mutually orthogonal. The connection direction X corresponds to the connection direction of the terminal, or the extension direction of the terminal and the main body. The width direction Y and the height direction Z correspond to the intersecting directions that intersect with the connection direction X. Furthermore, unless otherwise specified, the directions used in the following explanation represent the directions when each part is assembled to each other. Note that "orthogonal" here includes approximately orthogonal.

[0012] As shown in Figure 1, the coupler device 1 comprises a first terminal 2, a second terminal 3, and a main body 4. The coupler device 1 is a device that connects the first terminal 2 and the second terminal 3 within the main body 4, and by connecting the first terminal 2 and the second terminal 3, the first wire W1 to which the first terminal 2 is attached and the second wire W2 to which the second terminal 3 is attached can be connected. The coupler device 1 is mounted, for example, on a vehicle. The first wire W1 and the second wire W2 constitute, for example, wires, cables, etc., of a control system or power system in a vehicle.

[0013] The first terminal 2 is a terminal attached to the end of the first electric wire W1, and is, for example, a crimp terminal that is crimped to the end of the first electric wire W1. The first terminal 2 has an electric wire connection portion 21, a connecting portion 22, and an electrical connection portion 23. The electric wire connection portion 21, the connecting portion 22, and the electrical connection portion 23 are made of conductive metal and are integrally formed, for example, by pressing and bending a single sheet of metal that has been punched out into shapes corresponding to each portion. The first terminal 2 is formed in the order of electric wire connection portion 21, connecting portion 22, and electrical connection portion 23 in the extending direction (connection direction X) and is interconnected with one another.

[0014] The first electric wire W1 is constructed, for example, by providing an insulating coating on the outer circumference of the conductor portion, with the end portion exposing the conductor portion, and the first terminal 2 is attached to that end. That is, the wire connection portion 21 of the first terminal 2 is attached by crimping the conductor portion and the insulating coating portion of the first electric wire W1 together. The connecting portion 22 is the part that connects the wire connection portion 21 and the electrical connection portion 23. A recess 22A is formed in the connecting portion 22. The recess 22A is a recessed portion that is lower in height compared to the adjacent wire connection portion 21 and electrical connection portion 23. The electrical connection portion 23 is the part that is electrically connected to the second terminal 3, and is formed, for example, in a box shape. The first terminal 2 is a female terminal, and a connection hole 26 is formed in the electrical connection portion 23 for inserting the terminal portion 36 of the second terminal 3. The connection hole 26 extends from the end face of the electrical connection portion 23 in the direction of extension of the second terminal 3.

[0015] As shown in Figure 2, a terminal portion 27 is formed on the electrical connection portion 23 of the first terminal 2. The terminal portion 27 is, for example, a contact piece formed in the connection hole 26, and contacts the terminal portion 36 of the second terminal 3 to electrically connect with the terminal portion 36.

[0016] In Figure 1, the second terminal 3 is a terminal attached to the end of the second electric wire W2, and is, for example, a crimp terminal that is crimped to the end of the second electric wire W2. The second terminal 3 has an electric wire connection portion 31, a connecting portion 32, and an electrical connection portion 33. The electric wire connection portion 31, the connecting portion 32, and the electrical connection portion 33 are made of conductive metal and are integrally formed, for example, by pressing and bending a single sheet of metal that has been punched out into shapes corresponding to each portion. The second terminal 3 is formed in the order of electric wire connection portion 31, connecting portion 32, and electrical connection portion 33 in the extending direction (connection direction X) and is interconnected with one another.

[0017] The second electric wire W2 is constructed, for example, by providing an insulating coating on the outer circumference of the conductor portion, with the end portion exposing the conductor portion, and the first terminal 2 is attached to that end. That is, the wire connection portion 31 of the second terminal 3 is attached by crimping the conductor portion and the insulating coating portion of the second electric wire W2 together. The connecting portion 32 is the part that connects the wire connection portion 31 and the electrical connection portion 33. A recess 32A is formed in the connecting portion 32. The recess 32A is a recessed portion that is lower in height compared to the adjacent wire connection portion 31 and electrical connection portion 33. The electrical connection portion 33 is the part that is electrically connected to the first terminal 2, and is formed, for example, in a box shape. The second terminal 3 is a male terminal, and a terminal portion 36 is formed on the electrical connection portion 33 that is connected to the terminal portion 27 of the first terminal 2. The terminal portion 36 is a tab-shaped terminal that extends from the end face of the electrical connection portion 33 in the direction of extension of the second terminal 3, and is, for example, a plate or a rod.

[0018] In Figure 1, the main body 4 is a component for inserting and connecting the first terminal 2 and the second terminal 3. It is made of an insulating material such as resin and has a rectangular cross-sectional shape. The main body 4 is a non-divisible, elongated body that extends in the direction of extension and is not a structure that can be divided, nor is it a structure made by joining two or more members. For this reason, the main body 4 has a simple structure and can be easily manufactured at low cost by resin molding or the like.

[0019] The main body portion 4 forms an insertion space 41 along the extending direction. The insertion space 41 is a hole that penetrates the main body portion 4 in the extending direction. For example, it has a rectangular cross-section and is formed with a size that allows the insertion of the first terminal 2 and the second terminal 3. That is, the insertion space 41 enables the insertion of the first terminal 2 from one first opening 47 and the insertion of the second terminal 3 from the other second opening 48. The insertion space 41 includes a first terminal accommodation chamber 41A for accommodating the first terminal 2 and a second terminal accommodation chamber 41B for accommodating the second terminal 3. The first terminal accommodation chamber 41A is a space for accommodating the first terminal 2, and for example, it is the space in the insertion space 41 from the first opening 47 to the guide portion 46. The second terminal accommodation chamber 41B is a space for accommodating the second terminal 3, and for example, it is the space in the insertion space 41 from the second opening 48 to the guide portion 46.

[0020] In FIG. 2, a first through-hole 42 is formed in the main body portion 4. The first through-hole 42 is a hole for inserting the first locking portion 52 of the first spacer 5 and is formed in the first terminal accommodation chamber 41A of the insertion space 41. The first through-hole 42 is a hole that communicates the first terminal accommodation chamber 41A with the outside of the main body portion 4 and is formed at the position where the recess 22A of the first terminal 2 is disposed. That is, the first through-hole 42 is formed at a position where the inserted first locking portion 52 can enter the recess 22A.

[0021] Also, a first tapered portion 43 is formed in the main body portion 4. The first tapered portion 43 is a part that smoothens the insertion of the first terminal 2 into the insertion space 41 and is formed within the insertion space 41. That is, the first tapered portion 43 is formed by inclining the inner surface of the insertion space 41, and the inner surface of the insertion space 41 is tapered from the first opening 47 side along the extending direction toward the insertion direction of the first terminal 2. The first tapered portion 43 is formed on the insertion path of the first terminal 2 in the insertion space 41 and is formed at a position closer to the first opening 47 than the second opening 48. By forming the first tapered portion 43, when the first terminal 2 is inserted into the main body portion 4, the first terminal 2 can be guided to an appropriate insertion position, and the insertion of the first terminal 2 can be performed smoothly.

[0022] The main body part 4 is formed with a second communication hole 44. The second communication hole 44 is a hole for inserting the first locking part 52 of the second spacer 6, and is formed in the second terminal accommodation chamber 41B of the insertion space 41. The second communication hole 44 is a hole that communicates the second terminal accommodation chamber 41B with the outside of the main body part 4, and is formed at the position where the recess 32A of the second terminal 3 is arranged. That is, the second communication hole 44 is formed at a position where the inserted second locking part 62 can enter the recess 32A.

[0023] Also, the main body part 4 is formed with a second tapered part 45. The second tapered part 45 is a part that smoothens the insertion of the second terminal 3 into the insertion space 41, and is formed within the insertion space 41. That is, the second tapered part 45 is formed by inclining the inner surface of the insertion space 41, and is formed such that the inner surface of the insertion space 41 tapers from the second opening 48 side along the extending direction towards the insertion direction of the second terminal 3. The second tapered part 45 is formed on the insertion path of the second terminal 3 in the insertion space 41, and is formed at a position closer to the second opening 48 than the first opening 47. By forming the second tapered part 45, when the second terminal 3 is inserted into the main body part 4, the second terminal 3 can be guided to an appropriate insertion position, and the insertion of the second terminal 3 can be performed smoothly.

[0024] The main body part 4 is formed with a guide part 46. The guide part 46 is a part that guides the terminal part 36 of the second terminal 3 towards the first terminal accommodation chamber 41A side within the insertion space 41, and is formed within the insertion space 41. That is, the guide part 46 is a protrusion that projects the inner surface 41C of the insertion space 41 towards the central position of the insertion space 41, and two are formed so as to sandwich the terminal part 36 from above and below. That is, the two guide parts 46 are located between the first terminal accommodation chamber 41A and the second terminal accommodation chamber 41B, and project from the ceiling surface and the floor surface of the inner surface of the insertion space 41 towards their respective formed positions.

[0025] The guide portion 46, like the second tapered portion 45, is provided projecting outwards from the inner surface of the insertion space 41, tapering towards the insertion direction of the second terminal 3. This allows the terminal portion 36 to be guided to the appropriate position and supported in the appropriate position when the second terminal 3 is inserted into the main body portion 4. The distance between the tips of the two guide portions 46 is, for example, narrower than the thickness of the electrical connection portion 23 of the first terminal 2 and wider than the thickness of the terminal portion 36 of the second terminal 3. By setting the distance between the two guide portions 46 in this way, the terminal portion 36 can be inserted between the guide portions 46, but the electrical connection portion 23 cannot be inserted between the guide portions 46. Therefore, the guide portion 46 can guide the insertion of the terminal portion 36. In addition, the guide portion 46 can function as a stopper when the first terminal 2 is inserted.

[0026] In Figure 1, a first spacer 5 is formed on the main body 4. The first spacer 5 is a part for locking the first terminal 2, which is inserted into the insertion space 41. The first spacer 5 has a first pivot body 51, a first locking part 52, and a first hinge part 53, and is formed integrally with the main body 4, for example by resin molding. The first pivot body 51 is provided on the side surface 4A of the main body 4, supported by the first hinge part 53, and is rotatable about an axis A1 that intersects the extending direction (connection direction X). The first hinge part 53 is a part that rotatably supports the first pivot body 51 and is provided on the side surface 4A of the main body 4. For example, the first hinge part 53 is provided near the center of the main body 4, extends toward the end of the main body 4, and curves by deformation, causing the first pivot body 51 to rotate so as to move away from and closer to the main body 4. Figure 1 shows the first rotating body 51 separated from the main body 4. The first locking portion 52 protrudes from the first rotating body 51 and is inserted into the insertion space 41 by the rotation of the first rotating body 51, locking the first terminal 2. That is, the first locking portion 52 protrudes from the surface of the first rotating body 51 facing the main body 4 and is inserted into the first communication hole 42 by the rotation of the first rotating body 51 and fits into the recess 22A of the first terminal 2. In this way, the first locking portion 52 locks and holds the first terminal 2.

[0027] The first rotating body 51 is provided with a first engaging portion 54. The first engaging portion 54 is a part for hooking the first rotating body 51 to the main body 4. The first engaging portion 54 protrudes from the surface of the first rotating body 51 facing the main body 4 and forms a first engaging hole 54A that penetrates in the width direction Y. For example, two first engaging portions 54 are formed at the end of the first rotating body 51 in the width direction Y. The first engaging portion 54 engages with a protruding first engaged portion 491 formed on the main body 4 to hook the first rotating body 51 so that it does not rotate. That is, when the first rotating body 51 rotates so that it approaches the main body 4 and becomes parallel to the side surface 4A, the first engaging portion 54 inserts the first engaged portion 491 into the first engaging hole 54A and engages with the first engaged portion 491. As a result, the first rotating body 51 is hooked to the main body 4 and rotation that would cause it to move away from the main body 4 is restricted.

[0028] A second spacer 6 is formed on the main body 4. The second spacer 6 is a part for locking the second terminal 3, which is inserted into the insertion space 41. The second spacer 6 has a second pivot body 61, a second locking part 62, and a second hinge part 63, and is formed integrally with the main body 4, for example by resin molding. The second pivot body 61 is provided on the side surface 4A of the main body 4, supported by the second hinge part 63, and is rotatable about an axis A2 that intersects the extending direction (connection direction X). The second hinge part 63 is a part that rotatably supports the second pivot body 61 and is provided on the side surface 4A of the main body 4. For example, the second hinge part 63 is provided near the center of the main body 4, extends toward the end of the main body 4, and curves by deformation, causing the second pivot body 61 to rotate so as to move away from and closer to the main body 4. Figure 1 shows the second rotating body 61 separated from the main body 4. The second locking portion 62 protrudes from the second rotating body 61 and is inserted into the insertion space 41 by the rotation of the second rotating body 61, locking the second terminal 3. Specifically, the second locking portion 62 protrudes from the surface of the second rotating body 61 facing the main body 4 and is inserted into the second communication hole 44 by the rotation of the second rotating body 61, and fits into the recess 32A of the second terminal 3. In this way, the second locking portion 62 locks and holds the second terminal 3.

[0029] The second rotating body 61 is provided with a second engaging portion 64. The second engaging portion 64 is a part for hooking the second rotating body 61 to the main body 4. The second engaging portion 64 protrudes from the surface of the second rotating body 61 facing the main body 4 and forms a second engaging hole 64A that penetrates in the width direction Y. The second engaging portion 64 engages with a protruding second engaged portion 492 formed on the main body 4, hooking the second rotating body 61 to prevent it from rotating. That is, when the second rotating body 61 rotates to approach the main body 4 and become parallel to the side surface 4A, the second engaging portion 64 inserts the second engaged portion 492 into the second engaging hole 64A and engages with the second engaged portion 492. As a result, the second rotating body 61 is hooked to the main body 4 and rotation that would cause it to move away from the main body 4 is restricted.

[0030] As described above, the main body 4 is integrally formed with the first spacer 5 having a first locking portion 52 and the second spacer 6 having a second locking portion 62. Therefore, when forming the main body 4 by resin molding, the main body 4 including the first spacer 5 and the second spacer 6 can be molded with a single mold, eliminating the need to prepare separate molds for molding the first spacer 5 and the second spacer 6, and allowing the main body 4 and the first spacer 5 and second spacer 6 to be manufactured at low cost.

[0031] Next, the connection of electric wires using the coupler device 1 according to this embodiment will be described.

[0032] The coupler device 1 is used to connect the first terminal 2 and the second terminal 3, thereby electrically connecting the first wire W1 and the second wire W2. To connect the wires using the coupler device 1, first, as shown in Figure 3, the first terminal 2 is inserted into the main body 4. The first terminal 2 is inserted into the insertion space 41 through the first opening 47 and is pushed towards the back of the insertion space 41. At this time, since the first tapered portion 43 is formed inside the insertion space 41, the first terminal 2 is smoothly inserted into the insertion space 41 without getting caught.

[0033] When the tip of the first terminal 2 comes into contact with the guide portion 46, the first terminal 2 can no longer be inserted further into the insertion space 41, and the insertion of the first terminal 2 is completed. At this time, the recess 22A of the first terminal 2 is positioned at the opening of the first communication hole 42 in the connection direction X.

[0034] Then, as shown in Figure 4, the second terminal 3 is inserted into the main body 4. The second terminal 3 is inserted into the insertion space 41 through the second opening 48 and is pushed towards the back of the insertion space 41. At this time, since the second tapered portion 45 is formed inside the insertion space 41, the second terminal 3 is inserted smoothly into the insertion space 41 without getting caught.

[0035] Then, the terminal portion 36 of the second terminal 3 passes between the two guide portions 46 and is inserted into the connection hole 26 of the first terminal 2. At this time, the guide portions 46 guide the terminal portion 36 along the correct path, allowing the terminal portion 36 to be smoothly inserted into the connection hole 26. The terminal portion 36 then contacts and connects with the terminal portion 27 of the first terminal 2. At this time, the recess 32A of the second terminal 3 is positioned at the opening of the second communication hole 44 in the connection direction X.

[0036] Then, the first terminal 2 is locked by the first spacer 5. That is, the first rotating body 51 of the first spacer 5 is rotated from a state where it is separated from the main body 4 to a state where it is close to the main body 4, and the first locking part 52 is inserted into the first communication hole 42. Then, the first locking part 52 passes through the first communication hole 42 and is inserted into the recess 22A of the first terminal 2. As a result, the first terminal 2 is locked by the first locking part 52 and cannot be removed from the insertion space 41. At this time, the first engaging part 54 formed on the first rotating body 51 is hooked onto the first engaged part 491 of the main body 4. Therefore, the rotation of the first rotating body 51 away from the main body 4 is restricted. Thus, the state in which the first terminal 2 is locked by the first locking part 52 can be maintained. Note that this locking of the first terminal 2 may be performed after insertion of the first terminal 2 but before insertion of the second terminal 3.

[0037] Furthermore, the second terminal 3 is locked by the second spacer 6. That is, the second rotating body 61 of the second spacer 6 is rotated from a state separated from the main body 4 to a state approaching the main body 4, and the second locking part 62 is inserted into the second communication hole 44. Then, the second locking part 62 passes through the second communication hole 44 and is inserted into the recess 32A of the second terminal 3. As a result, the second terminal 3 is hooked onto the second locking part 62 and cannot be removed from the insertion space 41. At this time, the second engaging part 64 formed on the second rotating body 61 is hooked onto the second engaged part 492 of the main body 4. Therefore, the rotation of the second rotating body 61 away from the main body 4 is restricted. Thus, the state in which the second terminal 3 is locked by the second locking part 62 can be maintained. Note that this locking of the second terminal 3 may be performed immediately after insertion of the second terminal 3.

[0038] Then, when the first terminal 2 and the second terminal 3 are attached to the main body 4, the first terminal 2 and the second terminal 3 become connected within the main body 4. As a result, the first wire W1 and the second wire W2 are electrically connected, and the wire connection by the coupler device 1 is completed.

[0039] As described above, the coupler device 1 according to this embodiment connects the first wire W1 and the second wire W2 using the first terminal 2, the second terminal 3, and the main body 4, and can maintain this connection. Therefore, the coupler device 1 according to this embodiment does not require parts such as female and male couplers, and can reliably connect the first wire W1 and the second wire W2 while reducing the number of parts, thereby reducing costs.

[0040] Furthermore, in this embodiment, the coupler device 1 has a main body 4 that is a non-divisible, elongated body, allowing the main body 4 that connects the first terminal 2 and the second terminal 3 to have a simple structure. This makes it easier to manufacture the main body 4.

[0041] Furthermore, in this embodiment, the coupler device 1 has a guide portion 46 formed in the insertion space 41 of the main body portion 4, which allows the terminal portion 36 to be guided to the appropriate position when the second terminal 3 is inserted into the main body portion 4.

[0042] Furthermore, in this embodiment, the coupler device 1 has a first tapered portion 43 and a second tapered portion 45 formed in the insertion space 41 of the main body 4, allowing the first terminal 2 and the second terminal 3 to be smoothly inserted into the main body 4.

[0043] It should be noted that the coupler device according to the present invention is not limited to the embodiments described above, and various modifications are possible within the scope of the claims. The coupler device according to this embodiment may be constructed by appropriately combining the components of each embodiment and modified example described above.

[0044] For example, although the coupler device 1 according to the above embodiment was described in the case where it is mounted on a vehicle, it may also be used without being mounted on a vehicle. [Explanation of Symbols]
