Description

[Technical Field]

[0001] The present invention relates to an electrical junction box. [Background technology]

[0002] If a car's battery becomes over-discharged, it may be necessary to start the engine by using a battery in another car (hereafter referred to as a rescue vehicle) to supply power. In this case, the battery of the broken-down car and the battery of the rescue vehicle are connected with a booster cable.

[0003] Typically, a booster cable clip is brought close to the rescue terminal and clamped to connect the two. However, in this case, if there is not enough space above the rescue terminal to clamp the clip, the rescue terminal and the booster cable cannot be connected. Therefore, a method has been proposed in which the booster cable is brought close to the rescue terminal from a direction perpendicular to its axis (horizontal direction) and connected by clamping the clip (Patent Document 1). However, this method has the problem that the booster cable easily becomes detached from the rescue terminal. [Prior art documents] [Patent documents]

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An electric junction box is mounted with electronic components such as fuses and relays and is disposed in an engine compartment of a vehicle.

[0011] For the sake of convenience, the following definitions are used for "front," "rear," "left," "right," "upper," and "lower" as shown in Figures 1 to 5. The "front-rear direction," "left-right direction," and "upper-lower direction" intersect with each other. The left-right direction corresponds to the "side-by-side direction" of the present invention, the front-rear direction corresponds to the "intersecting direction" of the present invention, and the upper-lower direction corresponds to the "protruding direction" of the present invention.

[0012] 1, the electrical junction box 1 includes a plurality of electronic components 2, bolt terminals 3, bus bars 4, a resin block 5 that houses the electronic components 2, the bolt terminals 3, and the bus bars 4, a substantially rectangular cylindrical frame 6 that houses the block 5, a cap 9, and a support portion 10 (see FIG. 3). The electrical junction box 1 further includes an upper cover (not shown) that covers an upper opening of the frame 6, a lower cover (not shown) that covers a lower opening of the frame 6, and side covers (not shown) that cover the outer surfaces of the frame 6.

[0013] The electronic components 2 are composed of fuses, relays, etc., and are connected to bus bars 4, which will be described later.

[0014] In this embodiment, the bolt terminal 3 is attached to an LA terminal provided at the end of a power supply line (electric wire) connected to the battery. Two bolt terminals 3 are provided side by side in the left-right direction. The two bolt terminals 3 are arranged so that their axial directions are aligned in the up-down direction, with their tips pointing upward (towards the upper cover).

[0015] The bus bar 4 is formed by punching a metal plate and then bending it. The bus bar 4 has a terminal (not shown) to be connected to the electronic component 2, a connection portion 41 to be connected to the bolt terminal 3, and a relief terminal body 42 that constitutes the relief terminal 7. The terminal to be connected to the electronic component 2 has its tip pointing upward (toward the upper cover) and is shaped like a tuning fork or tab to match the shape of the terminal of the electronic component 2.

[0016] Connection portion 41 is formed in a plate shape with the thickness direction being the up-down direction, and is provided with a through-hole for passing bolt terminal 3. A plate-shaped LA terminal connected to the end of the battery's power supply line passes through bolt terminal 3, and the LA terminal is placed on connection portion 41. Furthermore, by screwing nuts 8 onto bolt terminal 3 from above connection portion 41 and the LA terminal, the LA terminal connected to the battery and connection portion 41 (busbar 4) are electrically connected.

[0017] In this embodiment, the relief terminal body 42 is provided in a plate shape, and is connected to the battery by connecting the above-mentioned LA terminal and the connecting portion 41. Details of the relief terminal body 42 will be described later.

[0018] Block 5 is made of an insulating resin material and has an electronic component accommodating section 51 that accommodates terminals connected to electronic component 2, a bolt accommodating section 52 that accommodates the lower end of bolt terminal 3, and a wall section 53 that forms the relief terminal.

[0019] The frame 6 is made of an insulating resin member and has a substantially rectangular cylindrical frame body 61 and a protective wall 62 supported by the frame body 61. The bolt accommodating portion 52 of the block 5 described above is provided adjacent to a rear wall portion 611 of the frame body 61. The power supply line connected to the LA terminal is accommodated between the rear wall portion 611 of the frame body 61 and the side cover, and is drawn out from the bottom side to the outside of the electrical junction box 1.

[0020] In this embodiment, the frame 6 has two protective walls 62, 62 that surround the two bolt terminals 3, respectively. The two protective walls 62, 62 are each provided to surround the bolt terminal 3 around its axis. In this embodiment, the protective walls 62 are provided to surround the front, left, and right sides of the bolt terminal 3, and are open on the rear side. The protective wall 62 is provided above the frame 6, so that the rear opening is not blocked by the frame 6. In this embodiment, the two protective walls 62, 62 are provided adjacent to each other in the left-right direction. As shown in FIG. 3 , the protective wall 62 that covers the front side of the left bolt terminal 3 protrudes further forward than the protective wall 62 that covers the front side of the right bolt terminal 3.

[0021] Next, we will explain the rescue terminal body 42 and wall portion 53 that constitute the rescue terminal 7 that is clipped by clip 11 attached to the end of the booster cable. As shown in Fig. 1 and other figures, the rescue terminal 7 is provided adjacent to the front side of the protective wall 62 (the side away from the bolt terminal 3) and protrudes upward beyond the protective wall 62. The rescue terminal body 42 is formed in a plate shape, and its thickness direction is along the front-to-rear direction, protruding upward.

[0022] The relief terminal body 42 is plate-shaped and is disposed with its thickness aligned in the front-to-rear direction. The relief terminal body 42 is disposed so that it is closer to the leftmost bolt terminal 3 of the two bolt terminals 3, 3 than to the other rightmost bolt terminal 3. In this embodiment, as shown in Fig. 3, the relief terminal 7 and the leftmost bolt terminal 3 are disposed side by side in the front-to-rear direction with the protective wall 62 sandwiched therebetween.

[0023] The wall portion 53 stands upright from the block 5 so as to cover the front side of the relief terminal body 42. As shown in Fig. 4, a plurality of ribs 531 extending in the vertical direction are provided on the front and rear surfaces of the wall portion 53, aligned in the left-right direction.

[0024] As shown in Fig. 3, a support part 10 that rotatably supports the cap 9 protrudes from the right side of the wall part 53. The cap 9 rotates around an axis that passes through the support part 10 in the front-to-rear direction. When the cap 9 is rotated to the right, the relief terminal 7 is exposed, and when the cap 9 is rotated to the left, the relief terminal 7 is covered and insulated.

[0025] Next, we will explain how to connect the clip 11 to the above-mentioned electrical connection box 1. As shown in Figures 1 and 2, the clip 11 has a pair of clamping parts 111, 111 that clamp an object between them, and the tips of the pair of clamping parts 111, 111 are biased in directions that move them closer to each other by a spring (not shown) or the like.

[0026] First, the upper cover (not shown) of the electrical junction box 1 is removed. Once the upper cover is removed, the cap 9 can be seen through the upper opening of the frame 6. Next, as shown in FIG. 1, the cap 9 is tilted toward the right to expose the relief terminal 7. Next, as shown in FIG. 2, the tips of the pair of clamping portions 111 are opened, and the tips of the pair of clamping portions 111 are oriented leftward and the rear ends are oriented rightward, and the clip 11 is brought close to the relief terminal 7 from the right side. Next, as shown in FIG. 5, the relief terminal 7 is clamped from the front and rear, and the clip 11 and the relief terminal 7 are connected. At this time, the clip 11 is mounted on the protective wall 62, as shown in FIG. 2. Furthermore, as shown in FIG. 5, the tip of the clip 11 is caught on a rib 531 provided on the wall portion 53, making it difficult for the clip 11 to come off the relief terminal 7.

[0027] According to the above-described embodiment, the protective wall 62 surrounds the axis of the bolt terminal 3 and protrudes upward beyond the bolt terminal 3. The relief terminal 7 is provided adjacent to the protective wall 62 on the side away from the bolt terminal 3 and protrudes upward beyond the protective wall 62. This allows the clip 11 to be mounted on the protective wall 62 when the clip 11 is clamped by approaching it from the side (right side in the left-right direction) of the relief terminal 7, thereby preventing the clip 11 from coming off the relief terminal 7. Furthermore, the protective wall 62 can be used as a mounting portion for the clip 11, eliminating the need to provide the protective wall 62 and the mounting portion separately, thereby enabling miniaturization. Furthermore, the clip 11 can be clamped by approaching it from the side of the relief terminal 7, allowing the clip 11 to be connected to the relief terminal 7 even if there is not much space above the electrical junction box 1.

[0028] According to the embodiment described above, a plurality of bolt terminals 3 are arranged side by side. A plurality of protective walls 62 are provided to surround each of the plurality of bolt terminals 3. The relief terminal 7 is arranged so that the distance to the leftmost bolt terminal 3 among the plurality of bolt terminals 3 is closer than the distance to the other bolt terminals 3. This increases the area of ​​the protective wall 62 on which the clip 11 can be mounted when the tip of the clip 11 faces leftward to clamp the relief terminal 7, allowing the clip 11 to be stably supported. This further prevents the clip 11 from coming off the relief terminal 7.

[0029] According to the above-described embodiment, the relief terminal 7 has a plate-shaped relief terminal body 42, and the relief terminal 7 is provided so that the plate thickness direction of the relief terminal body 42 is along the front-rear direction. This makes it even easier to clamp the relief terminal 7 from the side with the clip 11.

[0030] According to the embodiment described above, the wall portion 53 is provided with a plurality of ribs 531 aligned in the left-right direction along the vertical direction. This allows the ribs 531 to catch on the tip of the clip 11, further preventing the clip 11 from coming off the rescue terminal 7. Moreover, since the ribs 531 are also provided along the vertical direction, they do not affect the direction in which the mold for forming the block 5 is removed.

[0031] According to the embodiment described above, the support portion 10 protrudes from the right side of the wall portion 53 in the left-right direction and supports the cap 9 rotatably around an axis along the front-rear direction. This prevents the cap 9 from getting in the way when the clip 11 grips the rescue terminal 7 after the cap 9 is removed.

[0032] The present invention is not limited to the above-described embodiments, and can be appropriately modified, improved, etc. Furthermore, the material, shape, size, number, location, etc. of each component in the above-described embodiments are arbitrary and not limited as long as they can achieve the present invention.

[0035] According to the above-described embodiment, the relief terminal body 42 is provided in a plate shape, but this is not limited thereto. The relief terminal body 42 may be provided in a bolt shape similar to the bolt terminal 3.

[0036] According to the above-described embodiment, the relief terminal 7 includes the wall portion 53, but this is not limiting. The relief terminal 7 may be composed of only the relief terminal body 42.

[0037] According to the above-described embodiment, the wall portion 53 covers the front side of the relief terminal body 42, but this is not limited to this. The wall portion 53 may also cover the rear side of the relief terminal body 42.

[0038] According to the above-described embodiment, the wall portion 53 is provided on the block 5, but this is not limiting. The wall portion 53 may also be provided on the frame 6.
