Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in a conventional electrical connection box (electrical connection box unit), a stud bolt is inserted into a hole portion of a terminal in a wire with a terminal, and then a nut is screwed onto the stud bolt, whereby the wire with a terminal is fastened to the stud bolt. Therefore, the fastening of the wire with a terminal to the stud bolt is affected by the tightening condition of the nut on the stud bolt. In other words, if the tightening of the nut on the stud bolt is weak, there is a possibility that a desired fastening state of the wire with a terminal to the stud bolt cannot be obtained. For this reason, conventionally, a torque wrench or the like has been used to screw the nut onto the stud bolt and manage the fastening state of the wire with a terminal to the stud bolt. However, from the viewpoint of workability, it is preferable that the fastening state of the wire with a terminal to the stud bolt can be managed without using a torque wrench or the like.

[0005] The present invention has been made in view of the above-described circumstances, and its purpose is to provide an electrical connection box unit, a fastening structure for a terminal-equipped electric wire, and a terminal-equipped electric wire that can manage the fastening state of a terminal-equipped electric wire to a stud bolt by visual inspection. [Means for solving the problem]

It must be a wire with terminals. [Effects of the Invention]

[0012] An electric connection box unit, a fastening structure for a wire with a terminal, and a wire with a terminal according to the present invention will be described below. According to the present invention, a detection rib is provided at a bolt connection portion of a wire with a terminal, and the detection rib is configured to be displaceable from an initial position before fastening the wire with a terminal to a stud bolt to a fastening position after fastening. Specifically, at the initial position, it extends so as to rise in a direction intersecting the extending direction of the bolt connection portion, and at the fastening position, it is pressed by a nut by screwing the nut onto the stud bolt and is laid down from the initial position and extends along the extending direction.

[Modes for carrying out the invention]

[0015] <Embodiment> Embodiments of the present invention will be described below with reference to the drawings. The electrical junction box unit 100 consists of an electrical junction box 1 in which stud bolts S are provided in the internal space, an electric wire 50 with terminals fastened to the stud bolts S, and a nut 60 screwed onto the stud bolts.

[0016] The electrical junction box 1 is typically a relay box mounted on a vehicle, having an internal space for housing electronic components such as relays and other electronic components (not shown). In this example, the terminal wire 50 electrically connects the electrical junction box 1 to external equipment (not shown), such as the battery of the vehicle on which the electrical junction box 1 is mounted.

[0017] For the sake of explanation, we will define "front," "back," "left," "right," "up," and "down" as shown in Figures 1 to 6. The "front-back direction," "left-right direction," and "up-down direction" are orthogonal to each other.

[0018] <Electrical junction box 1> The following describes the general structure of the electrical junction box 1. As shown in Figures 1 and 2, the electrical junction box 1 consists of a frame 10, a lower cover 20 assembled below the frame 10 to close the lower end opening of the frame 10, an upper cover 30 assembled above the frame 10 to close the upper end opening of the frame 10, and a side cover 40 assembled to the side wall portion 11 to close the notch 14 of the frame 10. All four of the above components constituting the electrical junction box 1 are made of molded resin.

[0019] A stud bolt S is provided at the front end of the internal space of the electrical junction box 1. The stud bolt S is connected to the electronic components mounted in the electrical junction box 1 within the internal space via a busbar B (see Figures 3 and 5-6), and a wire 50 with a terminal connected to an external device such as a battery (not shown) is fastened to it, thereby enabling an electrical connection between the electronic components and the external device. The frame 10, lower cover 20, upper cover 30, and side cover 40 that constitute the electrical junction box 1 will be described in order below.

[0020] First, let's describe the frame 10. As shown in Figure 2, the frame 10 has a roughly rectangular cylindrical side wall portion 11 that extends in the vertical direction. The side wall portion 11 constitutes the majority of the external appearance of the side of the electrical junction box 1.

[0021] Multiple circumferential locations (three in this example) on the outer surface of the lower end of the side wall portion 11 are integrally provided with locking portions 12, each including a through hole extending in the vertical direction. The locking portions 12 have the function of assembling the lower cover 20 to the frame 10.

[0022] Multiple locking portions 13 are integrally provided on the outer surface of the upper end of the side wall portion 11 at multiple locations in the circumferential direction (two locations in this example). The locking portions 13 have the function of assembling the upper cover 30 to the frame 10.

[0023] A notch 14 is formed in the side wall portion 11 at the location corresponding to the stud bolt S on the right front side, where a portion of the side wall portion 11 is cut inward. A wire 50 with a terminal, which is fastened to the stud bolt S, is placed in the notch 14, and a locking portion (not shown) is provided therein. The locking portion has the function of assembling the side cover 40 to the frame 10.

[0024] Next, the lower cover 20 will be described. As shown in Figure 2, the lower cover 20 integrally comprises an annular side wall portion 21 that constitutes most of the external appearance of the lower side surface of the electrical junction box 1, and a bottom wall portion 22 that closes the annular lower end opening of the side wall portion 21 and constitutes most of the external appearance of the bottom surface of the electrical junction box 1. The annular upper end edge of the side wall portion 21 has a shape that corresponds to the annular lower end edge of the side wall portion 11 of the frame 10, and is capable of being fitted with the annular lower end edge of the side wall portion 11.

[0025] Multiple locking pieces 23 extending upward are integrally provided on the outer surface of the upper end of the side wall portion 21 at multiple locations in the circumferential direction (eight locations in this example), corresponding to multiple locking portions 12 of the frame 10.

[0026] Next, the upper cover 30 will be described. As shown in Figure 2, the upper cover 30 integrally comprises an annular side wall portion 31 that constitutes most of the external appearance of the upper side surface of the electrical junction box 1, and an upper wall portion 32 that closes the annular upper end opening of the side wall portion 31 and constitutes most of the external appearance of the upper surface of the electrical junction box 1. The annular lower end edge of the side wall portion 31 has a shape that corresponds to the annular upper end edge of the side wall portion 11 of the frame 10, and is capable of being fitted with the annular upper end edge of the side wall portion 11.

[0027] Multiple circumferential locations (two locations in this example) on the outer surface of the lower end of the side wall portion 31 are integrally provided with downward-extending locking pieces 33, each containing a locking hole that penetrates in the front-rear direction, corresponding to multiple locking portions 13 of the frame 10.

[0028] Next, the side cover 40 will be described. As shown in Figure 2, the side cover 40 has a side wall portion 41 that extends vertically and is roughly rectangular in shape when viewed from above, corresponding to the notch 14 of the frame 10. The side wall portion 41 (in particular the right side wall portion 41) constitutes a part of the external appearance of the side of the electrical connection box 1. The side wall portion 41 is integrally provided with a guide wall 42 that extends downward and guides the wire 52 of the terminal-equipped wire 50.

[0029] The outer surfaces of the front side wall portion 41 and the rear side wall portion 41 are integrally provided with locking projections 43 that protrude shortly outward, corresponding to the locking portion (not shown) of the frame 10.

[0030] The frame 10, lower cover 20, upper cover 30, and side cover 40 that constitute the electrical junction box 1 have been described above. In order to obtain the electrical junction box 1 consisting of the frame 10, lower cover 20, upper cover 30, and side cover 40, it is necessary to assemble the lower cover 20, upper cover 30, and side cover 40 to the frame 10, respectively.

[0031] To assemble the lower cover 20 to the frame 10, the multiple locking pieces 23 (see Figure 2) of the lower cover 20 are inserted from below into the multiple through holes of the locking portion 12 (see Figure 2) of the frame 10. From this position, the annular upper end edge of the side wall portion 21 of the lower cover 20 is fitted onto the annular lower end edge of the side wall portion 11 of the frame 10, and the multiple locking pieces 23 are locked to the multiple locking portions 12. This completes the assembly of the lower cover 20 to the frame 10.

[0032] To assemble the upper cover 30 to the frame 10, the locking portion 13 (see Figure 2) of the frame 10 is inserted into the locking holes of the multiple locking pieces 33 (see Figure 2) of the upper cover 30. From this position, the annular lower end edge of the side wall portion 31 of the upper cover 30 is fitted onto the annular upper end edge of the side wall portion 11 of the frame 10, and the multiple locking pieces 33 are locked to the multiple locking portions 13. This completes the assembly of the upper cover 30 to the frame 10.

[0033] To assemble the side cover 40 to the frame 10, the front and rear side walls 41 of the side cover 40 are inserted into the notch 14 of the frame 10 so as to close the notch 14, and the multiple locking protrusions 43 (see Figure 2) of the side cover 40 are locked to the locking parts (not shown) of the notch 14 in the frame 10. This completes the assembly of the side cover 40 to the frame 10. The side cover 40 is assembled to the frame 10 after the terminal wires 50 are fastened to the stud bolts S7.

[0034] In this way, the electrical junction box 1 is completed by assembling the lower cover 20, upper cover 30, and side cover 40 to the frame 10, respectively. The order in which the lower cover 20, upper cover 30, and side cover 40 are assembled to the frame 10 does not matter.

[0035] When the electrical junction box 1 is assembled, the locking of multiple locking pieces 23 with multiple locking parts 12 prevents the lower cover 20 from separating downward from the frame 10. Furthermore, the locking of multiple locking pieces 33 with multiple locking parts 13 prevents the upper cover 30 from separating upward from the frame 10. Furthermore, the locking of multiple locking protrusions 43 with multiple locking parts in the notch 14 prevents the side cover 40 from separating to the right from the frame 10.

[0036] <50mm wire with terminals> The terminal-equipped wire 50 will now be described. As shown in Figures 3 and 4, the terminal-equipped wire 50 consists of a roughly L-shaped terminal 51 and a wire 52 to which the terminal 51 is connected. One end of the terminal-equipped wire 50 is connected (fastened) to a stud bolt S, and the other end is connected to an external device.

[0037] As shown in Figure 4, the terminal 51 is integrally constructed with a wire connection portion 53 that extends vertically and connects to the electric wire 52, and a bolt connection portion 54 that extends rearward from the upper end of the wire connection portion 53 and fastens to the stud bolt S. The bolt connection portion 54 is provided with a hole 55 that penetrates vertically and through which the stud bolt S is inserted. The bolt connection portion 54 has a gap 57 that is cut out from the right edge to approximately the center in the left-right direction.

[0038] A detection rib 56 is integrally provided at the left end of the bolt connection portion 54 and at the left end of the frame portion defining the gap 57. In other words, the left detection rib 56 is provided at the left end of the bolt connection portion 54, and the right detection rib 56 is provided at the left end of the edge portion defining the gap 57 in the bolt connection portion 54. These pair of detection ribs 56 are arranged so as to sandwich the hole portion 55 in the left-right direction.

[0039] The detection rib 56 is configured to be displaceable from an initial position before fastening the terminal-equipped wire 50 to the stud bolt S to a fastened position after fastening the terminal-equipped wire 50 to the stud bolt S. Specifically, the detection rib 56 extends upward in the direction intersecting the left-right direction in the initial position (more specifically, the left detection rib 56 extends diagonally upward to the left, and the right detection rib 56 extends diagonally upward to the right) (see Figures 4 and 5), and in the fastened position, it is pressed down by the nut 60 when the nut 60 is screwed onto the stud bolt S, and extends downward from the initial position along the left-right direction (see Figure 6). The detection rib 56 has the function of detecting the detection state of the terminal-equipped wire 50 to the stud bolt S.

[0040] As shown in Figures 3 and 5-6, the electric wire 52 is composed of a conductor core wire 58 and an insulating sheath 59 that surrounds the conductor core wire 58. The conductor core wire 58 may be a single wire or a stranded wire in which multiple conductors are twisted together.

[0041] <Nut 60> The nut 60 will now be described. As shown in Figures 3 and 5 to 6, the nut 60 is integrally constructed from a main body 61 and a flange 62 positioned at the lower edge of the main body 61. The flange 62 extends radially outward from the main body 61 over its entire circumferential area. The nut 60 is not limited to the above, as it is a known nut that can realize the present invention.

[0042] <Fastening structure of terminal-equipped electric wire 50> The fastening structure of the terminal-equipped electric wire 50 will now be described. As shown in Figures 5 and 6, the stud bolt S of the electrical connection box 1 is inserted through the hole 55 of the terminal-equipped electric wire 50, and the bolt connection portion 54 and the busbar B are brought into adjacent contact in the vertical direction.

[0043] Next, the nut 60 is screwed onto the stud bolt S. During the screwing of the nut 60 onto the stud bolt S, the flange portion 62 of the nut 60 comes into contact with the detection rib 56 of the terminal-equipped wire 50 (see Figure 5). In this state, if the screwing of the nut 60 onto the stud bolt S continues, the detection rib 56 is pressed by the nut 60 (flange portion 62) and begins to bend downward so that it extends in the left-right direction. Furthermore, if the screwing of the nut 60 onto the stud bolt S continues, the detection rib 56 bends completely so that it extends in the left-right direction (see Figure 6). As a result, the terminal-equipped wire 50 is fastened to the stud bolt S.

[0044] When the terminal-equipped wire 50 is fully fastened to the stud bolt S, the right-hand detection rib 56 is positioned within the gap 57, and the upper surface of the right-hand detection rib and the upper surface of the bolt connection portion 54 are approximately flush (see Figure 6). Similarly, the upper surface of the left-hand detection rib 56 is also approximately flush with the upper surface of the bolt connection portion 54 (see Figure 6). In this way, when the terminal-equipped wire 50 is sufficiently fastened to the stud bolt S, the detection rib 56 is not raised relative to the bolt connection portion 54 (i.e., it is tilted). In other words, the fastening status of the terminal-equipped wire 50 to the stud bolt S can be confirmed by visually observing the position of the detection rib 56. This allows the fastening status of the terminal-equipped wire to the stud bolt to be managed visually without the need for a torque wrench or the like.

[0045] Furthermore, by positioning the detection rib 56 in the gap 57 defined in the bolt connection portion 54 at the fastening position, it is possible to suppress the enlargement of the terminal-equipped electric wire 50, and consequently, the enlargement of the electrical connection box unit 100.

[0046] <Other forms> Furthermore, the present invention is not limited to the embodiments described above, and can be modified, improved, etc., as appropriate. In addition, the material, shape, dimensions, number, placement, etc. of each component in the embodiments described above are arbitrary and not limited, as long as they can achieve the present invention.

[0047] For example, the detection rib 56 may be configured to interfere with the upper cover 30 if the upper cover 30 is assembled to the frame 10 while the terminal wire 50 is not sufficiently fastened to the stud bolt S. This prevents the electrical junction box unit 100 from being completed with insufficient fastening of the terminal wire 50 to the stud bolt S.

[0048] Herein, the features of the embodiments of the electrical connection box unit, the fastening structure for the terminal-equipped wire, and the terminal-equipped wire according to the present invention described above are briefly listed below in [1] to [5].
