Description

Technical Field

[0001] This invention relates to a connector. Background Technology

[0002] To date, a connector is known comprising a first housing, a second housing capable of mating to the first housing, a first conductive member housed in the first housing, and a second conductive member housed in the second housing and electrically connected to the first conductive member. The connector also includes a bolt, which is a fastening member fastened to a fastening portion to electrically connect the first and second conductive members to each other (see JP2016-213048A).

[0003] In the connector, a first conductive component and a second conductive component are provided with through holes, which are arranged at positions where the first housing and the second housing mate with each other. Bolts are inserted into the respective through holes and tightened to the fastening parts, thereby electrically connecting the first conductive component and the second conductive component to each other. Summary of the Invention

[0004] Incidentally, in the connector disclosed in JP2016-213048A, bolts are inserted into the first conductive member and the second conductive member. Therefore, for example, even when the first and second housings are mated together while the fastening member is temporarily held by the fastening part, the fastening member cannot be inserted into the through hole, and mating cannot be achieved. Consequently, when the first and second housings are to be mated together, the fastening member needs to be removed, and in addition to the management of connector storage, management of fastening member storage is also required, leading to reduced assemblability.

[0005] This invention was made in view of such problems in the prior art. Furthermore, the object of this invention is to provide a connector that improves assemblability.

[0006] The connector according to the invention includes: a first housing; a second housing configured to engage with the first housing; a first conductive member housed in the first housing; a second conductive member housed in the second housing and electrically connected to the first conductive member; and a fastening member configured to electrically connect the first conductive member and the second conductive member to each other by fastening to a fastening portion, wherein the first conductive member and the second conductive member are provided with an overlap portion, and when the first housing and the second housing engage with each other, the first conductive member and the second conductive member are arranged to overlap each other at the overlap portion, the fastening portion is arranged on one side of the overlap portion in the overlap direction, and the fastening member is fastened to the fastening portion, pressing the overlap portion toward the overlap direction, and electrically connecting the first conductive member and the second conductive member to each other.

[0007] According to the present invention, a connector that improves assemblability can be provided. Attached Figure Description

[0020] Referring to the accompanying drawings, the connector according to this embodiment is described in detail below. Note that the dimensions in the drawings are exaggerated for ease of explanation and may differ from the actual scale.

[0021] like Figure 1 As shown, connector 1 according to this embodiment electrically connects two electrical components (omitted in the figure), such as a power supply and a device, or a device and a device, to each other. Connector 1 includes a first housing 3 and a second housing 5. The first housing 3 houses a first conductive component 7 electrically connected to an electrical component (see figure 5). Figure 2 The second housing 5 houses a second conductive component 9 that is electrically connected to another electrical component (see...). Figure 2 And can be fitted to the first housing 3. When the first housing 3 and the second housing 5 are fitted together, the first conductive member 7 and the second conductive member 9 are arranged to overlap each other. The overlapping first conductive member 7 and the second conductive member 9 are electrically connected to each other by fastening member 11 (see...). Figure 2 Therefore, these two electrical components are electrically connected to each other.

[0022] like Figures 1 to 12 As shown, connector 1 includes a first housing 3, a second housing 5, a first conductive component 7, a second conductive component 9, and a fastening component 11.

[0023] like Figures 1 to 3 and Figures 5 to 7 As shown, the first housing 3 is formed of a conductive material such as a metal. Note that the first housing 3 can also be formed of an insulating material such as a synthetic resin. The first housing 3 is formed in an L-shaped housing form, allowing the first conductive component 7 to be accommodated therein and the second housing 5 to be fitted therein. The first housing 3 includes a plurality of (specifically, two in this case) first receiving portions 13 that internally accommodate the first conductive component 7 and a fitting portion 15 that internally accommodates the second housing 5. The first receiving portions 13 and the fitting portion 15 extend tubularly in mutually orthogonal directions and communicate with each other internally. On the outside of the first housing 3, a plurality of fixing portions 17 are provided for fixing to an electrical component via a plurality of bolts. On the outer periphery of one end side of the first receiving portion 13, a first sealing member 19 is arranged, which is in close contact with an electrical component and seals the space between the first housing 3 and the electrical component. A sealing retainer 21, assembled to close the opening of the first receiving portion 13, maintains the arrangement position of the first sealing member 19 relative to the first housing 3. An opening is provided in the sealing retainer 21, through which the first conductive component 7 is exposed. On the other end of the first receiving portion 13, a plurality of openings 23 are provided (specifically, two in this case) for inserting fastening members 11, which electrically connect the first conductive member 7 and the second conductive member 9, into the plurality of openings 23. A plurality of engaging portions 25 are provided on the inner surface of the openings 23 and are arranged at equal intervals in the circumferential direction (the rotation direction of the fastening members 11) to form a shape with concave and convex features.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the second housing 5 is formed of an insulating material such as synthetic resin. The second housing 5 is shaped to accommodate the second conductive member 9 internally and to fit into the mating portion 15 of the first housing 3. On the outside of the second housing 5, a locking portion (omitted in the figure) is provided, which engages with a locked portion (omitted in the figure) provided in the mating portion 15 of the first housing 3. When the locking portion and the locked portion engage with each other, the mating state between the first housing 3 and the second housing 5 is maintained. The second housing 5 includes a plurality of (specifically, two in this case) second receiving portions 27 in which the second conductive member 9 is accommodated. Each of the two sides of the second receiving portion 27 in the longitudinal direction is open, exposing a portion of the second conductive member 9, and allowing a wire 29 electrically connected to the second conductive member 9 to be led out to the outside. The end of the wire 29 leading out from the second housing 5 is electrically connected to another electrical component. A wire sealing member 31 is arranged on the outer periphery of the wire 29 located inside the second receiving portion 27. This wire sealing member 31 is in close contact with the second housing 5 and seals the space between the second housing 5 and the wire 29. A wire sealing retainer 33, assembled to close the lead-out side opening of the wire 29 in the second receiving portion 27, maintains the arrangement position of the wire sealing member 31 relative to the second housing 5. On the outer periphery of the opening side of the second receiving portion 27, which exposes a portion of the second conductive member 9, a second sealing member 35 is arranged in close contact with the first housing 3 and seals the space between the first housing 3 and the second housing 5. On the outer periphery of the second housing 5 on the first housing 3 side, a housing shielding member 37 is installed. This housing shielding member 37 is electrically connected to the first housing 3 and forms a shielding circuit when mated to the mating portion 15 of the first housing 3. On the outer periphery of the second housing 5 on the wire 29 side, a wire shielding member 39 is installed. This wire shielding member 39 is electrically connected to a shielding member (omitted in the figure) covering the outer periphery of the wire 29 leading out from the second housing 5 and forms a shielding circuit. The housing shielding component 37 and the wire shielding component 39 form a shielding circuit, and thus prevent noise and the like from entering the connector 1 and from leaking from the connector 1.

[0025] like Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figures 8 to 10As shown, the first conductive member 7 is formed of a conductive material such as a metal and is formed into a plate-like shape such as a busbar. Multiple (specifically, two in this case) first conductive members 7 are used. The first conductive member 7 is formed into a U-shape by bending both end sides in the same direction. One end side of the first conductive member 7 serves as a component connection portion 41 for electrical connection with an electrical component. The component connection portion 41 is arranged such that it protrudes from the opening of the sealing retainer 21 outside the first housing 3 while the first conductive member 7 is housed in the first receiving portion 13 of the first housing 3. A through hole is formed in the component connection portion 41, and a nut is fixed at a position corresponding to the through hole on the inner side of the first housing 3. With one conductive member (omitted in the figure) arranged on the side of the electrical component, a bolt (omitted in the figure) is inserted into the through hole and tightened to the nut, thus the component connection portion 41 electrically connects the first conductive member 7 and an electrical component to each other. The other end side of the first conductive member 7 serves as a first connection portion 43 for electrical connection to the second conductive member 9. The first connecting portion 43 is U-shaped and includes a pair of opposing portions 45 and 45 arranged at intervals facing each other, and a connecting portion 47 connecting the pair of opposing portions 45 and 45 to each other. The space between the pair of opposing portions 45 and 45 is set to allow the insertion of the second conductive member 9 when the first housing 3 and the second housing 5 are engaged. The connecting portion 47 is arranged in such a position that, when the first housing 3 and the second housing 5 are engaged, the second conductive member 9 can be inserted between the pair of opposing portions 45 and 45. One of the opposing portions 45 ( Figure 8 The upper opposing portion 45 is provided with a through hole 49, into which the fastening member 11 can be inserted. On the outer surface of the opposing portion 45, a fastening portion 51 formed by a nut is fixed and arranged at a position corresponding to the through hole 49, and the fastening member 11 can be fastened to the fastening portion 51. When the fastening portion 51 is arranged at one opposing portion 45, it is not necessary to provide a fastening portion such as a terminal block for fastening the fastening member 11 for the first housing 3 or the second housing 5. Thus, the structure of the first housing 3 and the second housing 5 can be simplified. A pair of opposing portions 45 and another opposing portion 45 ( Figure 8 The lower opposing portion 45 is provided with a contact portion 53 protruding toward one of the opposing portions 45. When the first conductive member 7 is housed in the first receiving portion 13 of the first housing 3, the first connecting portion 43 is arranged inside the first housing 3 at a position corresponding to the opening 23 of the first receiving portion 13.

[0026] like Figure 2 , Figure 4 and Figure 11As shown, the second conductive member 9 is formed of a conductive material such as a metal and is formed into a plate shape such as a busbar. Multiple (specifically, two in this case) second conductive members 9 are used corresponding to the first conductive member 7. The second conductive member 9 is formed with a straight shape extending in a direction orthogonal to the straight portion of the first conductive member 7. One end of the second conductive member 9 serves as a wire connection portion 55 electrically connected to the end of the wire 29. The wire connection portion 55 is joined to the end of the wire 29 by crimping or the like, electrically connecting the second conductive member 9 and the wire 29 to each other. The other end of the second conductive member 9 serves as a second connection portion 57 electrically connected to the first connection portion 43 of the first conductive member 7. The second connection portion 57 is arranged such that it protrudes from the opening of the second receiving portion 27 outside the second housing 5 while the second conductive member 9 is housed in the second receiving portion 27 of the second housing 5. The second connection portion 57 is arranged to be sandwiched between a pair of opposing portions 45, and thus overlaps with the first connection portion 43 of the first conductive member 7 inside the first housing 3 when the first housing 3 and the second housing 5 are engaged. The overlapping portion 59 is formed by the overlapping portion of the first connecting portion 43 and the second connecting portion 57.

[0027] Inside the first housing 3, an overlapping portion 59 is arranged at a position corresponding to the opening 23. In the overlapping portion 59, on one side of the overlapping direction of the first connecting portion 43 and the second connecting portion 57, a fastening portion 51 is arranged at a position closest to the opening 23. In the overlapping portion 59, the second connecting portion 57 is provided with a contact hole 61 formed by a through hole accommodating the contact portion 53. Note that the contact hole 61 can be formed as a recess in the surface of the second conductive member 9 instead of a through hole. In the overlapping portion 59, the contact portion 53 is accommodated in the contact hole 61. In this case, the arrangement position of the first conductive member 7 and the second conductive member 9 in contact with each other can be maintained, and the reliability of the electrical connection between the first conductive member 7 and the second conductive member 9 can be maintained. In the opening 23, the fastening member 11 is fastened to the fastening portion 51. In this case, in the overlapping portion 59, the first connecting portion 43 (another opposing portion 45) and the second connecting portion 57 are in contact with each other, and therefore the first conductive member 7 and the second conductive member 9 are electrically connected to each other.

[0028] like Figure 2 , Figure 3 , Figures 5 to 7 and Figure 12 As shown, a plurality of (specifically, two in this case) fastening members 11 are used in correspondence with a plurality of first conductive members 7 and a plurality of second conductive members 9 (specifically, two each in this case). The fastening members 11 include a shaft portion 63 and a resin portion 65.

[0029] The shaft portion 63 is formed of, for example, a metal material. The shaft portion 63 extends along the extending direction of the first receiving portion 13 of the first housing 3. The outer periphery of the shaft portion 63 is formed in a bolt-like shape to be fastened to the fastening portion 51. The length of the shaft portion 63 is set such that its end protruding from the fastening portion 51 can press against the second conductive member 9 (second connecting portion 57) when fastened to the fastening portion 51.

[0030] The resin portion 65 is formed of an insulating material such as synthetic resin and is disposed at one end of the shaft portion 63 exposed from the opening 23. The inner surface of the resin portion 65 is formed into a threaded shape that can be fastened to the shaft portion 63. Note that the resin portion 65 can be integrally inserted with the shaft portion 63, such that the shaft portion 63 is located inside the resin portion 65. The resin portion 65 includes an outer surface exposed from the opening 23, and this outer surface is formed into a polygonal shape, such as a hexagon, that can be fastened by a clamp or the like. On the outer periphery of the resin portion 65 located inside the opening 23, an O-ring is arranged, which is a sealing member that is in close contact with the first housing 3 and seals the space between the first housing 3 and the resin portion 65. On the outer periphery of the resin portion 65, a plurality of (specifically, three in this case) engaging tabs 67 are provided in an elastically deformable manner, and the free ends of the engaging tabs 67 can engage with a plurality of engaging portions 25 of the opening 23. When the shaft 63 rotates relative to the fastening part 51 in the fastening direction, the engaging piece 67 elastically deforms radially inward to release its engagement with the engaged part 25. Thus, when fastened to the fastening part 51, the shaft 63 can rotate in the fastening direction, and the first conductive member 7 and the second conductive member 9 can be stably electrically connected to each other. Conversely, when the shaft 63 rotates relative to the fastening part 51 in the fastening release direction, the engaging piece 67 remains engaged with the engaged part 25 without elastic deformation. Therefore, during the fastening process to the fastening part 51, the shaft 63 cannot rotate in the fastening release direction. Thus, without releasing the fastening state of the fastening member 11 relative to the fastening part 51, the conductive state between the first conductive member 7 and the second conductive member 9 can be stably maintained.

[0031] When the first conductive member 7 is housed in the first housing 3, the fastening member 11 is temporarily held by fastening the shaft portion 63 to the fastening portion 51 to a certain extent. While temporarily holding the fastening member 11, the end of the shaft portion 63 is prevented from protruding from the fastening portion 51. The first housing 3, which temporarily holds the fastening member 11, is fitted to the second housing 5, and the first conductive member 7 and the second conductive member 9 overlap each other to form an overlap portion 59 without interference from the fastening member 11. When the first housing 3 and the second housing 5 are fitted together, the fastening member 11 is fastened to the fastening portion 51 by rotating the resin portion 65 exposed from the opening 23 using a clamp or the like. When the fastening member 11 is fastened to the fastening portion 51, the front end of the shaft portion 63 exposed from the fastening portion 51 presses the second connecting portion 57 in the overlap portion 59 in the overlap direction, and the second connecting portion 57 and the first connecting portion 43 (another opposing portion 45) come into contact with each other. When the first connecting part 43 and the second connecting part 57 come into contact with each other due to the fastening of the fastening member 11, the first conductive member 7 and the second conductive member 9 are electrically connected to each other, and the two electrical components are electrically connected to each other.

[0032] The fastening member 11 is fastened to the fastening portion 51, pressing the overlapping portion 59, thereby electrically connecting the first conductive member 7 and the second conductive member 9 to each other. Therefore, it is not necessary to insert the fastening member 11 into the first conductive member 7 and the second conductive member 9. The fastening portion 51 to which the fastening member 11 is fastened is arranged on one side of the overlapping direction of the overlapping portion 59. Therefore, even when the fastening member 11 is temporarily held by the fastening portion 51, the fastening member 11 will not interfere with the first conductive member 7 and the second conductive member 9 in the overlapping portion 59. Therefore, even when the fastening member 11 is temporarily held by the fastening portion 51, the first housing 3 and the second housing 5 can still cooperate with each other. When the fastening member 11 is temporarily held, apart from the management of the connector 1, no management of the fastening member 11 is required, and assemblability is improved.

[0033] The connector 1 includes a first housing 3, a second housing 5 that mates with the first housing 3, a first conductive member 7 housed in the first housing 3, and a second conductive member 9 housed in the second housing 5 and electrically connected to the first conductive member 7. The connector 1 also includes a fastening member 11, which electrically connects the first conductive member 7 and the second conductive member 9 to each other by fastening to a fastening portion 51. Furthermore, the first conductive member 7 and the second conductive member 9 are provided with an overlapping portion 59, which is arranged to overlap each other at the overlapping portion 59 when the first housing 3 and the second housing 5 are mated. The fastening portion 51 is arranged on one side of the overlapping portion 59 in the overlapping direction. The fastening member 11 is fastened to the fastening portion 51, pressing the overlapping portion 59 towards the overlapping direction, and electrically connecting the first conductive member 7 and the second conductive member 9 to each other.

[0034] The fastening member 11 is fastened to the fastening portion 51, and the overlapping portion 59 is pressed, thereby electrically connecting the first conductive member 7 and the second conductive member 9 to each other. Therefore, it is not necessary to insert the fastening member 11 into the first conductive member 7 and the second conductive member 9. The fastening portion 51 to which the fastening member 11 is fastened is arranged on one side of the overlapping direction of the overlapping portion 59. Therefore, even when the fastening member 11 is temporarily held by the fastening portion 51, the fastening member 11 will not interfere with the first conductive member 7 and the second conductive member 9 in the overlapping portion 59. Therefore, even when the fastening member 11 is temporarily held by the fastening portion 51, the first housing 3 and the second housing 5 can still cooperate with each other. When the fastening member 11 is temporarily held, apart from the management of the connector 1, no management of the fastening member 11 is required, and assemblability is improved.

[0035] Therefore, in the connector 1 described above, the fastening component 11 can be temporarily held, and apart from the management of the connector 1, the fastening component 11 does not need to be managed, which improves assemblability.

[0036] Furthermore, one of the first housing 3 and the second housing 5 is provided with an opening 23 through which the fastening member 11 protrudes to the outside. The opening 23 is also provided with a plurality of engaging portions 25 arranged in the rotational direction of the fastening member 11. The fastening member 11 is also provided with an engaging piece 67, which can engage with the engaging portions 25 and is elastically deformable. Furthermore, when the fastening member 11 rotates in the fastening direction, the engaging piece 67 elastically deforms to release the engagement with the engaging portions 25, and when the fastening member 11 rotates in the unfastening direction, it prevents the engaging piece 67 from elastically deforming to maintain engagement with the engaging portions 25.

[0037] Therefore, when fastened to the fastening part 51, the fastening member 11 can rotate in the fastening direction, and the first conductive member 7 and the second conductive member 9 can be electrically connected to each other in a stable manner. Conversely, during the process of fastening to the fastening part 51, the fastening member 11 cannot rotate in the fastening release direction. Thus, in a state where the fastening member 11 is not loosened relative to the fastening part 51, the conductive state between the first conductive member 7 and the second conductive member 9 can be maintained stably.

[0038] Furthermore, one of the first conductive member 7 and the second conductive member 9 is provided with a pair of opposing portions 45 and 45, which are arranged to sandwich the other of the first conductive member 7 and the second conductive member 9 in the overlapping direction in the overlapping portion 59 when the first housing 3 and the second housing 5 are engaged with each other. In addition, a fastening portion 51 is arranged at one of the pair of opposing portions 45 and 45.

[0039] Therefore, it is not necessary to provide a fastening part, such as a terminal block, for fastening the fastening member 11 to the first housing 3 or the second housing 5, and the structure of the first housing 3 and the second housing 5 can be simplified.

[0040] Furthermore, the overlapping portion 59 is provided with a contact portion 53 protruding from one of the first conductive member 7 and the second conductive member 9 toward the other, and a contact hole portion 61 therein for accommodating the contact portion 53.

[0041] Therefore, by accommodating the contact portion 53 in the contact hole portion 61, the arrangement position of the first conductive member 7 and the second conductive member 9 in contact with each other can be maintained, and the reliability of the electrical connection between the first conductive member 7 and the second conductive member 9 can be maintained.

[0042] Although the present invention has been described above with reference to embodiments, the present invention is not limited thereto. Within the scope of the claims, the construction of the components can be replaced with any construction having the same function.

[0043] For example, two first conductive components and two second conductive components are provided (forming two groups), but the number is not limited to this. One first conductive component and one second conductive component (forming one group) or three or more first conductive components and three or more second conductive components (forming three or more groups) can be provided.

[0044] Furthermore, in the first housing, the first receiving portion and the mating portion extend in orthogonal directions, but are not limited thereto. The first receiving portion and the mating portion may extend in parallel directions. In this case, similar to the second conductive member, the first conductive member may be formed with a straight plate-like shape.

[0045] Furthermore, the opening is provided on the first housing, but is not limited thereto. When the overlapping portion is located inside the second housing, the opening may be provided on the second housing.

[0046] Furthermore, the contact portion is disposed on the first conductive member, and the contact hole portion is disposed on the second conductive member. However, the contact portion and the contact hole portion are not limited thereto. The contact portion may be disposed on the second conductive member, and the contact hole portion may be disposed on the first conductive member.
