[0006] Problem to be solved by the utility model

[0007] In some proposals, the following is suggested: using rigid, ribbon-like or rod-shaped cables to connect the inlet terminals and the charging circuit. Because rigid cables lack flexibility, it is difficult to significantly change the position of the inlet end. Furthermore, there are various standards for charging inlets, and the spacing of the inlet terminals varies depending on the standard. Therefore, when using rigid cables, a more flexible wire is needed to absorb any misalignment between the end position of the rigid cable and the inlet terminal position. However, wiring such wires is cumbersome and complicates the structure at the connection point.

[0008] Furthermore, Patent Document 1 discloses an adapter that relays the power supply connector of a charging station to the vehicle entrance. However, this adapter is a component designed to absorb differences in connector shape outside the vehicle and cannot be applied to situations where rigid cables are used inside the vehicle.

[0009] Therefore, this specification discloses an inlet fitting that can absorb differences in the configuration of the inlet terminals and the tolerances of the rigid cable when using a rigid cable.

[0010] Methods for solving problems

[0011] The inlet accessory disclosed in this specification is an inlet accessory for relaying the inlet terminal and cable of the charging inlet in a vehicle. It is characterized by having: an accessory body; an inlet connection portion disposed on the accessory body and connected to the inlet terminal; and a cable mounting portion for mounting the cable, the cable mounting portion having: a slit formed on the accessory body; and a fastening member for mounting the cable and capable of sliding along the slit.

[0012] Effects of the utility model

[0013] According to the accessories disclosed in this specification, since the fastening parts can slide, they can absorb differences in the configuration of the inlet terminals and the tolerances of the rigid cables. Attached Figure Description

[0016] Figure 3 This is a sectional view of the accessory. Detailed Implementation

[0017] The structure of the inlet fitting 30 will now be described with reference to the attached drawings. Figure 1 A cross-sectional view of the area surrounding the charging inlet 12. Additionally, Figure 2 This is an exploded perspective view of accessory 30. Figure 3 This is a sectional view of accessory 30.

[0018] As is well known, vehicles include those with a secondary battery (not shown) capable of being charged using an external power source. The vehicle in question, in addition to the secondary battery, also includes a charging circuit (not shown) and a charging port 12. The charging circuit transforms and converts the power supplied from the external power source into AC / DC power before supplying it to the external power source.

[0019] The charging port 12 is a connector that allows for the attachment and removal of a charging connector for use with an external power source. The charging port 12 is, for example, located on the outer surface of the vehicle body 10. Figure 1 In one example, a recess is formed on the outer surface of the vehicle body 10, and the charging inlet 12 is disposed in the recess.

[0020] The charging port 12 has a housing 14 and a plurality of inlet terminals 18. The housing 14 is made of an insulating material such as resin. The housing 14 has a plurality of receiving sleeves 16, and the inlet terminals 18 are disposed inside the receiving sleeves 16. Typically, a plurality of terminals are also provided on the charging connector, and the terminals of the charging connector are inserted into the receiving sleeves 16 and, by contacting the inlet terminals 18, thereby electrically connecting an external power source to the charging port 12.

[0021] Multiple input terminals 18 are electrically connected to the charging circuit via rigid cables 24 and accessories 30. The rigid cable 24 is a strip or rod-shaped component made of conductive material. The rigid cable 24 is constructed by stamping or forming a sheet metal.

[0022] The rigid cable 24 involved is suitable for high-power transmission, but it lacks flexibility. Therefore, without using the accessory 30 described later, it is sometimes impossible to properly connect the accessory 30 to the inlet terminal 18. That is, as mentioned above, the accessory 30 lacks flexibility. Therefore, even if the shape error of the accessory 30 is within the tolerance range, the position of the tip of the accessory 30 may sometimes be offset relative to the corresponding inlet terminal 18, making it impossible to mount the tip of the accessory 30 onto the inlet terminal 18.

[0023] Furthermore, in recent years, various standards have been proposed for the charging port 12. Moreover, the spacing of the port terminals 18 varies depending on the type of specification. Such differences in terminal spacing cannot be absorbed by a rigid cable 24, which lacks flexibility. Therefore, even with a rigid cable 24 shaped for the first standard, there is a problem that the charging port 12 for the second standard cannot be used.

[0024] Therefore, some proposals suggest placing a flexible wire between the rigid cable 24 and the inlet terminal 18. Depending on the proposed structure, the wire can absorb any positional shift between the inlet terminal 18 and the rigid cable 24. However, using such a wire requires separate wiring between the wire and the inlet terminal 18, and between the wire and the rigid cable 24, which is cumbersome. Furthermore, the wire needs to be relatively thick to prevent overheating even under high power flow, thus increasing costs.

[0025] In this example, without using such a wire, an accessory 30 is provided for properly connecting the inlet terminal 18 and the rigid cable 24. Accessory 30 is a component that relays the connection between the inlet terminal 18 and the rigid cable 24. An inlet terminal 18 and a rigid cable 24 are mechanically and electrically connected to one accessory 30.

[0026] like Figure 2 As shown, accessory 30 has a main body 32, a first fastening bolt 52, and a second fastening bolt 54. The main body 32 also has a first piece 38 and a second piece 48. Both the first piece 38 and the second piece 48 are made of a metal with high thermal and electrical conductivity, such as aluminum. Furthermore, the first piece 38 and the second piece 48 are joined together by any joining means such as welding, bonding, or screwing.

[0027] The first piece 38 is roughly divided into an upper part 40 and a lower part 42. A connecting hole 44 extending through the thickness direction is formed on the upper part 40. The periphery of this connecting hole 44 functions as an inlet connection portion 34 for connection with the inlet terminal 18. For a more detailed explanation, as follows... Figure 3 As shown, an internal thread 20 extending axially from its base end is formed on the inlet terminal 18. The connecting hole 44 is smaller than the outer diameter of the inlet terminal 18 and larger than the diameter of the internal thread 20. A first fastening bolt 52 is inserted into the connecting hole 44 from the opposite side of the inlet terminal 18 and engages with the internal thread 20 of the inlet terminal 18. Then, with the first fastening bolt 52 engaged with the internal thread 20, tightening the first fastening bolt 52 provides an electrical and mechanical connection between the inlet terminal 18 and the first module 38, and further to the accessory 30.

[0028] The lower part 42 is located below the upper part 40 and is less thick than the upper part 40. In other words, the first piece 38 is a shape obtained by cutting off half the thickness of the lower side of a rectangular piece. The second piece 48 is arranged in the rectangular space formed by this cutting.

[0029] On the lower part 42, a through hole, i.e. a slit 46, which is elongated in the width direction is formed. The height dimension of the slit 46 is greater than the diameter of the external thread of the second fastening bolt 54, which will be described later, and smaller than the diameter of the head 56 of the second fastening bolt 54.

[0030] The second piece 48 is a component fixed to the first piece 38 while overlapping its lower portion 42 in the thickness direction. A head opening 50 is formed in the second piece 48 at the location facing the slit 46. The head opening 50 is a generally rectangular opening that is elongated in the width direction. The height of the head opening 50 is only slightly larger than the diameter of the head 56 of the second fastening bolt 54. Therefore, when the head 56 of the second fastening bolt 54 is positioned in the head opening 50, the second fastening bolt 54 can slide in the width direction, while its rotation about an axis is restricted.

[0031] The head uses an opening 50, a slit 46, and a second fastening bolt 54 as a cable mounting part 36 for mounting the rigid cable 24 (symbol only shown in the diagram). Figure 3 And thus, it performs its function. That is, just as... Figure 2 , Figure 3 As shown, the second fastening bolt 54 is inserted into the slit 46 through the head opening 50. Since the height of the slit 46 is smaller than the diameter of the head 56, the head 56 remains in the head opening 50, while the external thread 57 protrudes outward through the slit 46. The external thread 57 protruding from the first block 38 is inserted into the connection hole 26 of the rigid cable 24. Then, in this state, the nut 58 is screwed into the external thread 57 and tightened. Here, the second fastening bolt 54 cannot rotate about its axis because its head 56 is located in the head opening 50. Therefore, the operator does not need to press the second fastening bolt 54 by hand when turning the nut 58. As a result, the tightening operation of the nut 58 can be simplified. Then, by fully tightening the nut 58, the rigid cable 24 is connected to the first block 38. And, thereby, the rigid cable 24 and the inlet terminal 18 are electrically connected via the first block 38.

[0032] Here, as explained so far, although the rigid cable 24 is mounted on the external thread 57 of the second fastening bolt 54, the second fastening bolt 54 is capable of sliding in the width direction. Therefore, even if the position of the connection hole 26 of the rigid cable 24 relative to the fitting 30 changes due to differences in the standard of the charging inlet 12 and shape deviations within the tolerance range of the rigid cable 24, this change in position can be absorbed by the sliding of the second fastening bolt 54. As a result, there is no need to change the shape of the rigid cable 24 according to the standard of the charging inlet 12, thereby enabling component standardization. Furthermore, this reduces the hassle or cost of wiring the charging inlet 12 and the rigid cable 24. In addition, since no wires are required, the structure can be simplified.

[0033] Furthermore, accessory 30 is made of a metal with high thermal conductivity, such as aluminum. Because of this structure, heat generated during power transmission can be effectively released, thus effectively preventing overheating of the component. Additionally, according to this example, the required heat dissipation performance of accessory 30 can be freely modified by changing the volume or material of the main body 32.
