R, The electric wire connection terminal portion is Among a straight line portion extending in an extension direction from the first bent portion toward the fastening portion on one end side and a straight line portion extending in an extension direction from the second bent portion toward the fastening portion on the other end side, the straight line portion is provided in a direction parallel to the straight line portion extending in the extension direction on one side. Power supply circuit components.

[0009] According to the power supply circuit member having the configuration of (1) above, a wire connection terminal portion capable of connecting to an external wire is provided between the fastening portions at both ends of the bus bar, so that an external wire can be branched and connected to the bus bar without releasing the fastening portions at both ends. Therefore, even if it becomes necessary to branch the power supply circuit later, this can be easily achieved by simply connecting the external wire to the wire connection terminal portion provided on the bus bar. In addition, since the bus bar has multiple bends, by adjusting the positions at which the bends are formed, the bus bar can be arranged in accordance with the variety of fastening objects, and the position of the wire connection terminal portion provided on the straight portion between the bends can also be easily adjusted.

[0010] (2) As the electric wire connection terminal portion, Between the first bend and the second bend A wire connection terminal piece is provided to protrude from a side edge of the bus bar in the straight portion, The housing is formed with a connector housing portion that receives the electric wire connection terminal piece and forms a connector that can be fitted with a connector of the external electric wire. The power supply circuit component according to (1) above.

[0013] According to the power supply circuit member having the above configuration (3), the direction in which the external electric wires connected to the electric wire connection terminal pieces of the bus bar extend can be set perpendicular to the straight portion between the two bent portions, so that mutual interference between the bus bar and the external electric wires can be suppressed as much as possible. In addition, the external electric wires connected to the electric wire connection terminal pieces of the bus bar can be extended in a direction parallel to the extending direction of the bus bar extending from the bent portion to the end portion, so that the wiring area of ​​the bus bar and the external electric wires can be compactly arranged. In addition, even in a state in which the external electric wires are not connected, the electric wire connection terminal pieces protrude from the straight portion between the two bent portions of the bus bar in a direction along the extending direction of the bus bar between the end portion of the bus bar and the bent portion. Therefore, if the portion of the bus bar extending from the bent portion to the end portion is considered as a "sleeve," the electric wire connection terminal pieces are hidden inside the sleeve, so that they are less likely to get in the way when wiring the bus bar.

[0014] (4) The plate is made of a strip and has fastening portions for fastening to the target member at both ends in the extending direction. The strip has a first bent portion and a second bent portion bent in a plane parallel to a plate surface of the strip, and a straight portion between the first bent portion and the second bent portion, A wire connection terminal piece capable of being connected to an external wire is protruded from a side edge of the strip plate in the straight portion.

Bus bar.

[0015] According to the bus bar having the above configuration (4), a wire connection terminal piece that can be connected to an external electric wire is protruded from the middle of the fastening parts at both ends of the bus bar, so that an external electric wire can be branched and connected to the bus bar without releasing the fastening parts at both ends. Therefore, even if it becomes necessary to branch the power supply circuit later, it can be easily realized by simply connecting the external electric wire to the wire connection terminal piece provided on the bus bar. In addition, since the bus bar has multiple bends, by adjusting the positions at which the bends are formed, it is possible to realize the wiring of the bus bar according to the variety of fastening objects, and it is also easy to adjust the position of the wire connection terminal piece provided on the straight part between the two bends. Effect of the Invention

[0016] According to the present invention, even for a bus bar whose fastening portions at both ends are already fastened to the fastening target members, it is possible to easily branch and connect an external electric wire later on without releasing the fastening, making it easy to add an additional power supply circuit later.

[0021] 1, a power supply circuit component 1 according to this embodiment includes a busbar 10 made of a highly conductive metal having fastening portions 11, 12 for a mounting target component at both ends in the extension direction, and a resin housing 30 formed along the extension shape of the busbar 10 to accommodate the busbar 10. The housing 30 is composed of an upper cover 30A and a lower cover 30B which are formed by splitting a strip plate constituting the busbar 10 in half in the thickness direction and combining them together.

[0022] Busbar 10 is formed in a strip shape, and has first bent portion 13 and second bent portion 14 bent in a plane parallel to the plate surface of the strip, as well as a straight portion 16 between both bent portions 13, 14. First bent portion 13 and second bent portion 14 are bent at right angles in the opposite direction as viewed from straight portion 16 located between both bent portions 13, 14.

[0023] The portions extending from the bent portions 13, 14 toward the fastening portions 11, 12 at both ends are configured as parallel straight portions 15, 17. Furthermore, right-angle bent portions 18, 19 that direct the fastening portions 11, 12 at both ends in opposite outward directions are provided on the straight portions 15, 17 extending toward the fastening portions 11, 12 at both ends near the fastening portions 11, 12. The fastening portions 11, 12 at both ends are configured as terminal portions in which mounting holes 11a, 12a for screw fastening are formed.

[0024] Furthermore, the busbar 10 has two electric wire connection terminal pieces (electric wire connection terminal portions) 21, 22 that can be connected to external electric wires W1, W2 at the side edges of the straight portion 16 between the first bent portion 13 and the second bent portion 14. The electric wire connection terminal pieces 21, 22 protrude from the side edges with an appropriate gap between them.

[0025] The electric wire connection terminal pieces 21, 22 are provided so as to protrude perpendicularly to the extending direction of the straight portion 16 between the first bent portion 13 and the second bent portion 14. In other words, the electric wire connection terminal pieces 21, 22 are provided so as to protrude in a direction parallel to the straight portion 15 extending from the first bent portion 13 toward the fastening portion 11 at one end.

[0026] Therefore, as shown in Figure 3, the terminals 101, 102 of the connectors C1, C2 of the external wires W1, W2 can be freely attached and detached to these wire connection terminal pieces 21, 22 in a direction perpendicular to the extension direction of the straight portion 16 between the first bent portion 13 and the second bent portion 14 (the direction of arrow S in Figures 1(a) and 3).

[0027] 1(a), the housing 30 is formed to accommodate each portion of the busbar 10 along the extending shape of the busbar 10. That is, the housing 30 is provided with first and second bent portions 33 and 34, straight portions 35, 36 and 37, and right-angle bent portions 38 and 39 as portions for accommodating the first bent portion 13, the second bent portion 14, the straight portions 16, 15 and 17, and the right-angle bent portions 18 and 19 of the busbar 10, respectively. In addition, the housing 30 is provided with portions 31 and 32 for drawing out the fastening portions 11 and 12 at both ends of the busbar 10.

[0028] In order to form a housing 30 having such a shape, as shown in FIG. 1(b), the upper cover 30A is provided with portions 31A, 32A, 33A, 34A, 35A, 36A, 37A, 38A, and 39A for forming these portions 31, 32, 33, 34, 35, 36, 37, 38, and 39, and the lower cover 30B is provided with portions 31B, 32B, 33B, 34B, 35B, 36B, 37B, 38B, and 39B.

[0029] The upper cover 30A and the lower cover 30B are provided with engagement portions 41A and 41B for locking them together when the upper cover 30A and the lower cover 30B are combined to form the housing 30 with the bus bar 10 accommodated therebetween.

[0030] The housing 30 is also provided with connector housing portions 51, 52 that accommodate the electric wire connection terminal pieces 21, 22 of the bus bar 10 to form connectors 26, 27 that can be fitted with the connectors C1, C2 of the external electric wires W1, W2. To form the connector housing portion 51, the upper cover 30A and the lower cover 30B are provided with connector housing components 51A, 51B that accommodate the electric wire connection terminal piece 21 therebetween. To form the connector housing portion 52, the upper cover 30A and the lower cover 30B are provided with connector housing components 52A, 52B that accommodate the electric wire connection terminal piece 22 therebetween.

[0031] The power supply circuit component 1, which is completed by accommodating the bus bar 10 in the housing 30, has portions 3, 4, 5, 6, 7, 8, and 9 which correspond to the bent portions 13, 14, straight portions 15, 16, 17, and right-angle bent portions 18, 19 of the bus bar 10, respectively, as shown in Figure 1(a).

[0032] According to the power supply circuit member 1 having the above configuration, the wire connection terminal pieces (wire connection terminal portions) 21, 22 capable of connector connection with the external wires W1, W2 are provided between the fastening portions 11, 12 at both ends of the busbar 10, so that the external wires W1, W2 can be branched and connected to the busbar 10 without releasing the fastening portions 11, 12 at both ends. Therefore, even if it becomes necessary to branch the power supply circuit later, this can be easily achieved by simply connecting the external wires W, W2 to the wire connection terminal pieces 21, 22 provided on the busbar 10 by a connector. In addition, since the busbar 10 has a plurality of bent portions 13, 14, by adjusting the positions at which the bent portions 13, 14 are formed, the busbar 10 can be arranged in accordance with the variety of fastening targets, and the positions of the wire connection terminal pieces 21, 22 provided on the straight portion 16 between the bent portions 13, 14 can also be easily adjusted.

[0033] In the power supply circuit member 1 configured as described above, the electric wire connecting terminal pieces 21, 22 provided on the bus bar 10 are housed in the connector housing parts 51, 52 to form the connectors 26, 27 for connecting to the connectors C1, C2 of the external electric wires W1, W2. Therefore, the external electric wires W1, W2 can be safely and easily connected and disconnected, and when not in use, the electric wire connecting terminal pieces 21, 22 can be protected from exposure to the outside, ensuring safety.

[0034] Furthermore, according to the power supply circuit member 1 having the above-described configuration, as shown in Figures 2 and 3, the extension direction of the external electric wires W1, W2 connector-connected to the wire connection terminal pieces 21, 22 of the bus bar 10 can be set to a direction perpendicular to the straight portion 16 between the two bent portions 13, 14, so that mutual interference between the bus bar 10, i.e., the power supply circuit member 1, and the external electric wires W1, W2 can be suppressed as much as possible.

[0035] Furthermore, the external electric wires W1, W2 connector-connected to the electric wire connection terminal pieces 21, 22 of the busbar 10 can be extended in a direction parallel to the extending direction of the busbar 10 extending from the first bent portion 13 to one fastening portion 11. Therefore, the busbar 10, i.e., the power supply circuit member 1 and the wiring area for the external electric wires W1, W2 can be kept compact. Furthermore, as shown in FIG. 1(a), even when the external electric wires W1, W2 are not connected, the electric wire connection terminal pieces 21, 22 protrude from the straight portion 16 between the two bent portions 13, 14 of the bus bar 10 in a direction along the extension direction of the bus bar 10 between the end portion (fastening portion 11) and the bent portion (first bent portion 13) of the bus bar 10. Therefore, if the portion (straight portion 15) of the bus bar 10 extending from the bent portion (first bent portion 13) toward the end portion (fastening portion 11) is considered to be a "sleeve," the electric wire connection terminal pieces 21, 22 are hidden inside the sleeve and are less likely to get in the way when wiring the bus bar.
