[Figure 3] FIG. 2 is an exploded perspective view of an insulating block and a nut. [Figure 4] FIG. 2 is an exploded perspective view of an insulating block and a bus bar. [Figure 5] FIG. 2 is an exploded perspective view of an insulating block that holds a bus bar and an inner terminal. DETAILED DESCRIPTION OF THE INVENTION

[0009] A connector according to one embodiment will be described in detail below with reference to the drawings. Note that the dimensional proportions in the drawings are exaggerated for the sake of convenience and may differ from the actual proportions.

[0010] Fig. 1 is a perspective view of a connector 1 according to one embodiment, and Fig. 2 is a partially exploded view of the connector 1.

[0011] The connector 1 is, for example, a high-voltage connector mounted on an electric vehicle or a hybrid vehicle. Hereinafter, an object to which the connector 1 is connected will be referred to as an "external connector," although this is not shown in the drawings. The direction in which the connector 1 connects to the external connector (hereinafter referred to as the "connection direction") corresponds to the Z direction in each drawing. In addition, along the connection direction, the side of the connector 1 that connects to the external connector may be referred to as the "front," and the opposite side may be referred to as the "rear." Note that Figures 1 and 2 show the connector 1 as viewed from a direction that allows the rear side to be seen.

[0012] Furthermore, with regard to various directions, the plane perpendicular to the connection direction is defined as the XY plane. The X and Y directions are perpendicular to each other. Hereinafter, the direction along the X direction may be referred to as the "width direction" of the connector 1, and the direction along the Y direction may be referred to as the "height direction" of the connector 1.

[0013] In this embodiment, the connector 1 is, for example, connected to the ends of two electric wires 100, a first electric wire 100a and a second electric wire 100b, each of which is routed externally. Each electric wire 100 has a core wire 101, which is a conductor, and a covering portion 102, which is an insulator that covers the core wire 101. In addition, at the end of each electric wire 100 that is connected to the connector 1, the covering portion 102 is removed, exposing a terminal portion 101a (see FIG. 5 ) of the core wire 101. Note that, although the core wire 101 may actually be composed of multiple strands, it is simply depicted as a single conductor member in FIGS. 1 and 2 .

[0014] The connector 1 includes a plurality of inner terminals 10, an insulating block 20, a plurality of bus bars 40, a plurality of outer terminals 50, a housing 60, a plurality of first bolts 70, and a plurality of second bolts 71.

[0015] Here, a combination including one each of the inner terminal 10, bus bar 40, outer terminal 50, first bolt 70, and second bolt 71 corresponds to one electric wire 100. In this embodiment, it is assumed that the connector 1 is connected to two electric wires 100, namely, the first electric wire 100a and the second electric wire 100b, and therefore there are two each of the inner terminal 10, bus bar 40, outer terminal 50, first bolt 70, and second bolt 71.

[0016] Each of the two inner terminals 10 is a terminal fitting manufactured by machining a sheet metal material having a certain thickness. In this embodiment, there is a first inner terminal 10a and a second inner terminal 10b that are identical in shape. The first inner terminal 10a is attached to an end of the first electric wire 100a. The second inner terminal 10b is attached to an end of the second electric wire 100b. The inner terminals 10 have a connecting portion 11 and a joining portion 12.

[0017] The connection portion 11 is a flat portion that is attached to the side surface portion 25 of the insulating block 20 while making contact with one of the bus bars 40. The connection portion 11 has a through portion 11a (see FIG. 5) through which a part of the second bolt 71 passes when the connection portion 11 is attached to the insulating block 20.

[0018] Hereinafter, a "reference direction" is defined as a direction for specifying various directions related to each part of the connector 1, such as the penetration direction of the through-portion 11a. The reference direction refers to a direction along which the first bolt 70 is fastened to the outer terminal 50. In this embodiment, the reference direction corresponds to the Z direction, which is the same as the connection direction of the connector 1. In this case, the penetration direction of the through-portion 11a when the inner terminal 10 is assembled to the connector 1 is a direction perpendicular to the reference direction, which corresponds to the X direction in this embodiment. Based on the condition that the connection portion 11 has the through-portion 11a penetrating in the X direction, the main plane of the connection portion 11 is parallel to the YZ plane. Furthermore, the planar shape of the connection portion 11 may be approximately rectangular with the long side in the Z direction and the short side in the Y direction.

[0019] The joining portion 12 is continuous with the connecting portion 11 in the reference direction and joins the terminal portion 101a of the core wire 101. In this embodiment, the joining portion 12 is a crimping portion that crimps the terminal portion 101a. However, the joining portion 12 is not limited to a crimping portion and may be, for example, a flat portion to one surface of which the terminal portion 101a is joined by ultrasonic welding.

[0020] Fig. 3 is an exploded perspective view of the insulating block 20 and two nuts 72 to be assembled to the insulating block 20. Fig. 4 is an exploded perspective view of the insulating block 20 after the two nuts 72 have been assembled and two bus bars 40 to be assembled to the insulating block 20. Figs. 3 and 4 show the insulating block 20 as viewed from a direction that allows the front side to be seen. Fig. 5 is an exploded perspective view of the insulating block 20 to which two inner terminals 10 are assembled after holding the two bus bars 40.

[0021] The insulating block 20 is made of, for example, synthetic resin, and holds the inner terminals 10 in a mutually insulated state. The insulating block 20 has a main body portion 21 and an extension portion 22.

[0022] The overall shape of the main body 21 is roughly a rectangular parallelepiped. The main body 21 has four sides: a front side 24, two side sides 25, and a rear end 26.

[0023] The front surface 24 is a surface having a normal direction in the Z direction. Of the side surfaces constituting the main body 21, the front surface 24 is the side surface closest to the bottom 62 of the housing 60 when the insulating block 20 is accommodated in the accommodation portion 63 of the housing 60. When two bus bars 40 are assembled to the insulating block 20, the first plate portions 41 of each bus bar 40 come into contact with the front surface 24.

[0024] The two side surface portions 25 are surfaces whose normal direction is opposite to each other along the X direction and have symmetrical shapes. The nut holding portions 25a provided on each side surface portion 25 each accommodate and hold a nut 72. The nuts 72 are fastened portions for fastening the second bolts 71. In this embodiment, there are two second bolts 71, and therefore there are two nuts 72, the same number as the second bolts 71. Note that the nuts 72 may be previously integrated into the insulating block 20 by insert molding during the manufacturing of the insulating block 20. When the two bus bars 40 are assembled to the insulating block 20, the second plate portion 42 of the first bus bar 40a contacts one side surface portion 25, and the second plate portion 42 of the second bus bar 40b contacts the other side surface portion 25.

[0025] The rear end portion 26 is an end portion that is opposite the front portion 24 in the direction opposite to the Z direction. Note that, as shown in Fig. 2, a part of the main body portion 21 including the rear end portion 26 may be configured with a combination of ribs. A part of the rear end portion 26 is continuous with the extension portion 22.

[0026] The main body 21 also has two accommodating holes 23, a first accommodating hole 23a and a second accommodating hole 23b. The accommodating holes 23 penetrate in the reference direction and are capable of accommodating a first bolt 70. That is, of the openings of the accommodating holes 23, a first opening 23c closer to the outer terminal 50 is formed in the front portion 24, and the opening opposite the first opening 23c is formed in the rear end portion 26. The first accommodating hole 23a is capable of accommodating the first bolt 70 fastened to the first outer terminal 50a, which is one of the outer terminals 50. The second accommodating hole 23b is capable of accommodating the first bolt 70 fastened to the second outer terminal 50b, which is the other outer terminal 50. The first accommodating hole 23a and the second accommodating hole 23b are arranged parallel to each other in the X direction. In other words, as shown in Figure 5, the direction in which one second bolt 71 is fastened to one nut 72 and the direction in which the other second bolt 71 is fastened to the other nut 72 are opposite to each other across the two accommodating holes 23.

[0027] In this embodiment, since the two storage holes 23 are arranged parallel to each other along the X direction, the height dimension corresponding to the Y direction of the rectangular parallelepiped shape of the main body 21 can be set narrower than the width dimension corresponding to the X direction.

[0028] The main body 21 also has groove-shaped busbar accommodating portions 27 that accommodate each busbar 40. In this embodiment, a busbar accommodating portion 27 is provided to correspond to each busbar 40. Specifically, one busbar accommodating portion is formed as a groove that accommodates the first busbar 40a and is continuous with a part of the front surface 24 and a part of one side surface 25. The other busbar accommodating portion is formed as a groove that accommodates the second busbar 40b and is continuous with a part of the front surface 24 and a part of the other side surface 25. The depth of the busbar accommodating portions 27 may be set so that the busbars 40 accommodated in the busbar accommodating portions 27 are not exposed beyond the outermost range of the main body 21, as shown in FIG. 5 .

[0029] Furthermore, the main body 21 has a notch 28 between the adjacent first accommodating hole 23a and second accommodating hole 23b. One end of the notch 28 in the Z direction is open on the front face 24 side, and the other end in the Z direction does not reach the rear end 26. The notch 28 also penetrates in the Y direction.

[0030] The extension portion 22 is a portion extending in the opposite direction to the Z direction from a middle position in the X direction of the rear end portion 26 of the main body portion 21. The extension portion 22 may be formed as a rib structure including two curved walls partially continuous with the two accommodating holes 23. The length of the extension portion 22 in the Z direction may be set to a length such that the two inner terminals 10 mounted to the insulating block 20 do not face each other in the X direction. Referring to FIG. 2 , the joint portion 12 of the first inner terminal 10a and the joint portion 12 of the second inner terminal 10b are blocked by the extension portion 22 and do not face each other. With this configuration, the extension portion 22 can further improve the insulating ability of insulating the two conductive paths from the electric wires 100 to the outer terminals 50 from each other while maintaining the strength of the insulating block 20.

[0031] The two bus bars 40 individually provide electrical continuity between the inner terminal 10 and the outer terminal 50. In this embodiment, there are a first bus bar 40a and a second bus bar 40b that have the same shape. The first bus bar 40a provides electrical continuity between the first inner terminal 10a and the first outer terminal 50a. The second bus bar 40b provides electrical continuity between the second inner terminal 10b and the second outer terminal 50b.

[0032] Each bus bar 40 is an L-shaped metal fitting manufactured by machining a sheet metal material having a certain thickness. Specifically, the bus bar 40 has a first plate portion 41 having a first through hole 41a formed therein and a second plate portion 42 having a second through hole 42a formed therein. A first bolt 70 is partially inserted through the first through hole 41a. A second bolt 71 is partially inserted through the second through hole 42a. Here, the "portion" of each bolt refers to the shank, including the threaded portion. That is, as shown in FIG. 4, when the bus bar 40 is assembled to the insulating block 20, the central axis of the first through hole 41a roughly coincides with the central axis of the receiving hole 23 corresponding to the first through hole 41a. Furthermore, as shown in FIG. 5, when the bus bar 40 is assembled to the insulating block 20, the central axis of the second through hole 42a roughly coincides with the central axis of the nut 72 corresponding to the second through hole 42a.

[0033] Each of the two outer terminals 50 has a portion exposed to the outside of the connector 1 and is connected to an external terminal provided on an external connector. In this embodiment, each outer terminal 50 is, for example, a rod-shaped male terminal made of metal. In this embodiment, there are a first outer terminal 50a and a second outer terminal 50b that have the same shape. The first outer terminal 50a is attached to the first plate portion 41 of the first bus bar 40a. The second outer terminal 50b is attached to the first plate portion 41 of the second bus bar 40b. The outer terminals 50 have a connecting portion 51 and a base portion 52.

[0034] The connecting portion 51 is an axial portion that is directly connected to a female terminal serving as an external terminal. In this embodiment, since it is assumed that the connecting direction of the connector 1 to an external connector is the Z direction, the axial direction of the connecting portion 51 also follows the Z direction.

[0035] Base 52 supports connecting portion 51 in the Z direction. Base 52 also has bolt hole 52a, for fastening first bolt 70, on the side opposite in the Z direction from the side supporting connecting portion 51. As described above, bolt hole 52a is formed in the reference direction corresponding to the Z direction.

[0036] The housing 60 is made of, for example, synthetic resin, and is an insulating member that protects the insulating block 20 by accommodating at least a portion of the insulating block 20. The housing 60 has a cylindrical portion 61 and a bottom portion 62.

[0037] The cylindrical portion 61 accommodates the insulating block 20 along the reference direction. In this embodiment, the width of the insulating block 20 along the X direction is longer than the height of the insulating block 20 along the Y direction. Therefore, the cross-sectional shape of the accommodation portion 63 set inside the cylindrical portion 61 is an elongated hole whose width is longer than its height. One opening of the accommodation portion 63 in the reference direction is an accommodation opening 61a that accommodates the insulating block 20. In other words, the accommodation opening 61a is an opening that allows each electric wire 100 to be led out of the connector 1 after assembly.

[0038] The bottom 62 closes the other opening of the accommodating portion 63 in the reference direction. However, the bottom 62 has at least a hole 62a that exposes the bolt hole 52a provided in the base 52 of each outer terminal 50 to the accommodating portion 63 of the tubular portion 61. In this embodiment, by fitting a part of the base 52 into the hole 62a, the two outer terminals 50 are supported by the housing 60 with each bolt hole 52a exposed to the accommodating portion 63.

[0039] The two first bolts 70 are first fastening members fastened to bolt holes 52a provided in the base 52 of the outer terminal 50. The two second bolts 71 are second fastening members fastened to nuts 72 as fastened portions provided on the side surface 25 of the insulating block 20 while partially passing through the through portion 11a of the inner terminal 10. Note that in this embodiment, bolts are used as both the first fastening members and the second fastening members, but other members may be used instead of bolts as long as they have a structure that can similarly connect the respective portions. Similarly, the fastened portions provided on the insulating block 20 may also be changed as appropriate to match the connection relationship with the second fastening members.

[0040] Next, a description will be given of the assembly of the connector 1. Hereinafter, it is assumed that the two electric wires 100 are configured as so-called electric wires with terminals, in which inner terminals 10 are individually attached to the ends of the electric wires 100.

[0041] First, as shown in FIG. 3, nuts 72 are attached to the two nut holders 25a provided on each side surface 25 of the insulating block 20, respectively.

[0042] Next, as shown in FIG. 4, bus bars 40 are held in two bus bar accommodating portions 27 formed so as to be continuous with a part of front surface portion 24 and a part of one side surface portion 25 of insulating block 20.

[0043] Next, as shown in FIG. 5 , the inner terminals 10 are respectively attached to the second plate portions 42 of the two bus bars 40 already held in the insulating block 20. Specifically, the connection portion 11 of the first inner terminal 10a is maintained in a position where it is stacked on the second plate portion 42 of the first bus bar 40a. At this time, the through portion 11a formed in the connection portion 11 is positioned relative to the second through hole 42a formed in the second plate portion 42 so that their central axes along the X direction are approximately aligned. Then, the shank of the second bolt 71 passes through the through portion 11a and the second through hole 42a and is fastened to the nut 72 already attached to the insulating block 20. As a result, the first inner terminal 10a is attached to the insulating block 20 while being in contact with the first bus bar 40a. Meanwhile, the second inner terminal 10b is similarly attached to the insulating block 20. Up to this point, the work of assembling the two bus bars 40 and the two inner terminals 10 to the insulating block 20 is carried out outside the accommodating portion 63 of the housing 60.

[0044] Next, after the two outer terminals 50 are supported in the corresponding holes 62a of the housing 60, the insulating block 20 with the inner terminals 10 assembled thereto is accommodated in the accommodating portion 63 through the accommodating opening 61a of the housing 60. At this time, the insulating block 20 is accommodated in the accommodating portion 63 along the reference direction corresponding to the Z direction, as shown in FIG.

[0045] Next, one of the first bolts 70 is inserted into the first accommodating hole 23a of the insulating block 20, and the shaft portion of the first bolt 70 passes through the first through-hole 41a formed in the first plate portion 41 of the first bus bar 40a and is fastened to the bolt hole 52a of the first outer terminal 50a. By fastening the first bolt 70, the first outer terminal 50a and the first bus bar 40a come into contact with each other, and the first outer terminal 50a and the insulating block 20 are assembled to the housing 60. Similarly, the other first bolt 70 is inserted into the second accommodating hole 23b of the insulating block 20, and the shaft portion of the first bolt 70 passes through the first through-hole 41a formed in the first plate portion 41 of the second bus bar 40b and is fastened to the bolt hole 52a of the second outer terminal 50b. By fastening the first bolts 70, the second outer terminals 50b and the second busbars 40b come into contact with each other, and the second outer terminals 50b and the insulating block 20 are assembled to the housing 60. At this time, as shown in FIG. 2 , each first bolt 70 is introduced into the accommodating hole 23 along the reference direction, which is the same as the introduction direction of the insulating block 20, and is fastened to the corresponding outer terminal 50.

[0046] Then, when the fastening by the first bolt 70 is completed, the assembly of the connector 1 is completed as shown in FIG.

[0047] Next, the effects of the connector 1 will be described.

[0048] The connector 1 includes an outer terminal 50, a first fastening member 70 fastened to a base portion 52 of the outer terminal 50, and an insulating block 20 having an accommodating hole 23 that can accommodate the first fastening member and penetrates in a reference direction along the fastening direction of the first fastening member. The connector 1 includes an inner terminal 10 that has a flat connecting portion 11 with a through-portion 11a that penetrates in a direction perpendicular to the reference direction and is attached to an end of an electric wire 100 routed from outside. The connector 1 also includes a second fastening member that partially penetrates the through-portion 11a of the inner terminal 10 and is fastened to a fastening portion provided on a side portion 25 of the insulating block 20. The connector 1 also includes an L-shaped bus bar 40 that has a first through-hole 41a through which a portion of the first fastening member penetrates and a second through-hole 42a through which a portion of the second fastening member penetrates, electrically connecting the outer terminal 50 and the inner terminal 10. The connector 1 also includes a cylindrical housing 60 that accommodates the insulating block 20 along the reference direction. A combination including one each of the outer terminal 50, the inner terminal 10, the receiving hole 23 of the insulating block 20, the bus bar 40, the first fastening member, and the second fastening member corresponds to one electric wire 100, and there are a plurality of such combinations.

[0049] In the above example, the first fastening member is a first bolt 70. In the above example, the second fastening member is a second bolt 71, and the fastened portion provided on the side surface portion 25 of the insulating block 20 is a nut 72 that fastens the second bolt 71. Furthermore, in the above example, the reference direction corresponds to the Z direction, and the penetration direction of the through portion 11a formed in the connection portion 11 of the inner terminal 10 corresponds to the X direction that is perpendicular to the Z direction as the reference direction.

[0050] According to the structure of the connector 1, multiple combinations of inner terminals 10 and outer terminals 50, etc., are each held by a single insulating block 20, thereby ensuring appropriate insulation between them. Furthermore, when assembling the connector 1, the work of assembling two bus bars 40 and two inner terminals 10 is consolidated into one work for a single insulating block 20 and is performed outside the accommodating portion 63 of the housing 60. Furthermore, the work of assembling the insulating block 20, to which the bus bars 40 and inner terminals 10 are attached, and the outer terminals 50 into the housing 60 is completed by fastening them with the first fastening members along the reference direction. In other words, when assembling the connector 1, it is not necessary to perform the work of fastening the inner terminals 10 and the work of fastening the bus bars 40 inside the accommodating portion 63 of the housing 60, which can be effective in improving workability.

[0051] As described above, according to this embodiment, it is possible to provide a connector 1 that improves the workability during assembly.

[0052] Furthermore, the structure of the connector 1 allows the inner terminals 10 and the bus bars 40 to have a common structure or shape for each combination of the inner terminals 10 and the outer terminals 50, etc. Therefore, the number of types of components required for the connector 1 can be reduced, which can contribute to simplifying the assembly work and reducing the manufacturing cost of the connector 1.

[0053] Furthermore, there may be two combinations of outer terminals 50, inner terminals 10, accommodating holes 23 of insulating block 20, bus bars 40, first fastening members, and second fastening members in connector 1. In insulating block 20, the direction in which one second fastening member is fastened to one fastened portion and the direction in which the other second fastening member is fastened to the other fastened portion may be opposite to each other across two accommodating holes 23 arranged in parallel with each other.

[0054] In the above example, the two accommodating holes 23 arranged in parallel to each other in the insulating block 20 are the first accommodating hole 23a and the second accommodating hole 23b.

[0055] According to this connector 1, when there are two combinations of the inner terminal 10 and the outer terminal 50, etc., it is possible to compactly arrange two accommodating holes 23 and two fastening portions in the insulating block 20. Therefore, this connector 1 can be advantageous in miniaturizing the insulating block 20, and therefore the connector 1 itself.

[0056] In the connector 1, the insulating block 20 may have a front surface 24 in which a first opening 23c of the accommodating hole 23 is formed, the first opening 23c being closer to the outer terminal 50. The bus bar 40 may have a first plate portion 41 in which a first through hole 41a is formed, and a second plate portion 42 in which a second through hole 42a is formed. The first plate portion 41 may be in contact with the front surface 24 of the insulating block 20. The second plate portion 42 may be in contact with a side surface 25 of the insulating block 20.

[0057] According to this connector 1, the first plate portion 41 and the second plate portion 42 of the bus bar 40, which has been simplified into an L shape, are assembled to fit the shape of the side portions of the insulating block 20. Therefore, if the insulating block 20 to which each bus bar 40 is assembled is considered to be a single unit, this can be advantageous for miniaturizing the entire unit, and ultimately the connector 1 itself.

[0058] Furthermore, in connector 1, insulating block 20 may have groove-shaped busbar accommodating portion 27 that accommodates busbar 40, so as to be continuous with part of front surface portion 24 and part of side surface portion 25.

[0059] According to this connector 1, since the bus bars 40 are assembled to the insulating block 20 while being accommodated in the bus bar accommodating portions 27, this can be advantageous in protecting the bus bars 40.

[0060] Furthermore, in the connector 1, the insulating block 20 may have a notch 28 between one receiving hole 23 and the other receiving hole 23 that are adjacent to each other.

[0061] In the above example, one of the two adjacent receiving holes 23 is the first receiving hole 23a and the other is the second receiving hole 23b.

[0062] According to this connector 1, the insulating block 20 is provided with the cutouts 28 that form spatial regions between the bus bars 40 or between the inner terminals 10, thereby improving the insulation properties.

[0063] Although one embodiment has been described above, the embodiment is not limited to this, and various modifications are possible within the scope of the gist of the embodiment. [Explanation of symbols]
