By the way, generally, the pair of clips of the booster cable incorporates an elastic member that generates a clamping force between the gripping portions of the pair of clips. Due to the characteristics of this elastic member, the gripping force of the pair of clips increases as the distance between the gripping portions of the pair of clips increases.

Therefore, when only the rescue terminal is clamped by the pair of clips of the booster cable, the distance between the gripping portions of the pair of clips is relatively narrow. For this reason, there is a problem that the clamping force of the pair of clips is reduced, and the pair of clips clamping the rescue terminal is easily detached from the rescue terminal.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and its object is to provide an electric connection box that can connect a pair of clips of a booster cable to a rescue terminal so as to prevent the clip from coming off the rescue terminal.

In order to achieve the above object, an electric connection box according to the present invention is characterized by the following [1] to [6].
[1]
An electrical connection box comprising a housing containing at least one electronic component, and a rescue terminal provided in the housing and connected to a pair of clips of a booster cable,
A gripping portion provided on the housing away from the rescue terminal so as to face the rescue terminal, wherein one of the clips contacts a surface of the clamping portion opposite to the rescue terminal, and the other a clamping portion that can be clamped by the pair of clips together with the rescue terminal so that the clip contacts a surface of the rescue terminal opposite to the clamping portion;
The holding portion includes an entry prevention portion for preventing the clip from entering a first space between the holding portion and the rescue terminal,
Must be an electric connection box.
[2]
In the electrical junction box described in [1] above,
The entry prevention unit is
A pair of projections protruding from a surface of the clamping portion facing the rescue terminal toward the rescue terminal so as to form a partial cylindrical inner surface having a common central axis with the rescue terminal. A pair of projections that allows the clip to enter the first space if the pair of projections is not present,
Must be an electric connection box.
[3]
The electrical connection box according to [1] or [2] above,
a peripheral wall portion provided in the housing and surrounding the rescue terminal continuously with the clamping portion;
A second space into which the other clip can enter is secured between the peripheral wall portion located on the side opposite to the holding portion with respect to the rescue terminal and the rescue terminal,
Must be an electric connection box.
[4]
In the electrical connection box according to any one of [1] to [3] above,
The holding portion is
A clamping wall provided in the housing away from the rescue terminal so as to face the rescue terminal, and a cap covering the clamping wall,
The entry prevention portion is provided on a surface of the cap facing the rescue terminal,
Must be an electric junction box.
[5]
In the electrical connection box described in [4] above,
The cap has, on the surface opposite to the rescue terminal, an engaging portion that engages with the one clip to prevent the clip from coming off.
Must be an electric junction box.
[6]
In the electrical junction box according to [4] or [5] above,
The holding wall and the cap have a locking structure on a surface facing the rescue terminal for preventing the cap from coming off the holding wall.
Must be an electric junction box.

According to the electrical connection box having the configuration [1] above, one clip contacts the surface of the holding portion opposite to the relief terminal, and the other clip contacts the surface of the relief terminal opposite to the holding portion. The rescue terminal and the clamping portion are clamped by a pair of clips. As a result, the gap between the gripping portions of the pair of clips is widened compared to the mode in which only the rescue terminal is clamped by the pair of clips, so the clamping force of the pair of clips is increased. As a result, it becomes difficult for the pair of clips holding the rescue terminal to come off from the rescue terminal. In addition, since an entry prevention portion is provided to prevent the clip from entering the first space between the clamping portion and the rescue terminal, one clip can be inserted into the first space for rescue. It is possible to prevent only the terminals from being clamped by a pair of clips.

According to the electrical connection box having the configuration [2], the pair of protrusions form a partially cylindrical inner surface having a common central axis with the relief terminal. Therefore, it is possible to prevent the clip from entering the first space while securing a columnar space for handling a tool used for tightening the fastening member fastened to the rescue terminal.

According to the electrical connection box having the configuration [3], the rescue terminal can be protected by the peripheral wall surrounding the rescue terminal while securing the second space into which the other clip can enter.

According to the electrical junction box having the configuration [4] above, when the electrical junction box is mounted on an electric vehicle, the electrical junction box is used with the clamping wall covered with the cap. Accordingly, when connecting the clip of the booster cable to the rescue terminal, the clip can be prevented from entering the first space between the holding portion and the rescue terminal. On the other hand, when the electric junction box is installed in a normal vehicle other than an electric vehicle (a vehicle in which the battery is installed in the space under the bonnet), the battery can be connected by directly connecting the booster cable to the battery terminal. Since it can be charged, there is no need to assume a situation where the clip of the booster cable is connected to the rescue terminal. Therefore, the electric junction box can be used with the cap removed from the holding wall. As a result, it is possible to share the housing of the electrical connection box between the electric vehicle and the normal vehicle.

According to the electrical connection box having the configuration [5] above, one clip contacts the surface of the holding portion opposite to the relief terminal, and the other clip contacts the surface of the relief terminal opposite to the holding portion. Thus, when the rescue terminal and the clamping portion are clamped by a pair of clips, the engaging portion of the cap engages with one of the clips, thereby preventing the clip from coming off from the clamping portion.

According to the electric connection box having the configuration [6], since the locking structure is provided at the location facing the first space where the clip cannot enter, the rescue terminal and the holding portion are held by the pair of clips. In doing so, the cap may be prevented from slipping out of the clamping wall due to unlocking of the locking structure due to contact of the clip with the locking structure.

As described above, according to the present invention, it is possible to provide an electrical junction box that can connect a pair of clips of a booster cable to a rescue terminal so as not to be easily detached from the rescue terminal.

The present invention has been briefly described above. Furthermore, the details of the present invention will be further clarified by reading the detailed description below with reference to the accompanying drawings.

<Embodiment>
Hereinafter, an electric connection box 1 according to an embodiment of the present invention shown in FIG. 1 will be described with reference to the drawings. The electrical junction box 1 is typically a relay box that is mounted in a space under the hood of an "electric vehicle" and houses electronic components such as relays. An electric vehicle is a vehicle that has an electric motor as a drive source and a battery that is mounted in a space different from the space under the bonnet (for example, the space under the rear seats), such as electric vehicles and hybrid vehicles. point to

Hereinafter, for convenience of explanation, "vertical direction", "top" and "bottom" in FIG. 1 are defined as "vertical direction", "top" and "bottom", respectively. When the electrical connection box 1 is mounted on the vehicle, the "vertical direction" corresponds to the vertical direction of the vehicle.

As shown in FIG. 1, the electrical connection box 1 made of resin includes a housing 10 that accommodates a plurality of electronic components 14 (see FIG. 2). In this example, the housing 10 includes a substantially rectangular frame-shaped frame 11 that houses a plurality of electronic components 14, an upper cover 12 that is assembled above the frame 11 so as to close the upper opening of the frame 11, and the frame 11. and a lower cover 13 assembled below the frame 11 so as to close the lower opening. All of the above three parts constituting the electrical junction box 1 are resin moldings.

In the electrical connection box 1, as shown in FIG. 2, a cylindrical relief terminal 20 is exposed to the outside when the upper cover 12 is removed, and is directed upward from a part of the upper surface of the frame 11. It is provided in the housing 10 (more specifically, the frame 11) so as to protrude from the bottom. In this example, the rescue terminal 20 is electrically connected inside the housing 10 to electric wires 51 and 52 (see FIGS. 1 and 2) extending from the housing 10 to the outside.

The electric wires 51 and 52 are respectively connected to an alternator and a battery (not shown) of the electric vehicle mounted in a space different from the space under the bonnet. Therefore, by connecting a pair of clips 61 (see FIG. 8) of the booster cable 60 to the rescue terminals 20 provided on the electric connection box 1 mounted in the space below the hood, the space below the hood and the can charge batteries of electric vehicles located in different spaces.

As shown in FIGS. 2 to 5, a sandwiching member projecting upward and extending in a predetermined direction (vertical direction in FIG. 3) is provided around the rescue terminal 20 in the housing 10 (more specifically, the frame 11). A portion 30 is provided so as to face the relief terminal 20 away from the relief terminal 20 . The clamping portion 30 is a portion that performs a function of being clamped by a pair of clips 61 of the booster cable 60 together with the relief terminal 20 (see FIG. 8).

In this example, as shown in FIG. 6, the holding portion 30 is composed of a holding wall 31 provided in the housing 10 (more specifically, the frame 11) and a cover 32 covering the holding wall 31. ing. The sandwiching wall 31 is a wall portion made of resin that is provided in the housing 10 (more specifically, the frame 11), protrudes upward, and extends in the predetermined direction.

The cover 32 made of resin or rubber has a shape that covers the upper surface, the side surface facing the rescue terminal 20 , and the side surface opposite to the rescue terminal 20 of the clamping wall 31 . By setting the color of the cover 32 that constitutes the appearance of the clamping part 30 to red, when the upper cover 12 of the electric connection box 1 is removed, the rescue terminal 20 located near the red cover 32 will connect the booster cable 60. You can tell at a glance that it is a terminal for connection.

A locking projection 33 projecting toward the rescue terminal 20 is formed on the side surface of the clamping wall 31 facing the rescue terminal 20, as shown in FIG. A locking hole (through hole) 34 is formed in the side surface of the cover 32 facing the rescue terminal 20, as shown in FIGS. Engagement between the locking projections 33 of the clamping wall 31 and the locking holes 34 of the cover 32 prevents the cap 32 from coming off the clamping wall 31 upward.

As shown in FIG. 5, the cap 32 is formed with an engaging portion 35 projecting away from the rescue terminal 20 and extending in the predetermined direction on the side opposite to the rescue terminal 20 . When the rescue terminal 20 and the clamping portion 30 are clamped by the pair of clips 61 of the booster cable 60, the engaging portion 35 engages with one of the clips 61 to prevent the clip 61 from coming off ( See Figure 8).

As shown in FIGS. 3 and 4 , the cap 32 has a pair of protrusions 36 projecting toward the rescue terminal 20 on the surface facing the rescue terminal 20 . The pair of protrusions 36 function to prevent the clip 61 of the booster cable 60 from entering the first space S1 (see FIGS. 3 and 6) between the rescue terminal 20 and the holding portion 30. . That is, without the pair of protrusions 26, the clip 61 can enter the first space S1. , the clip 61 cannot enter the first space S1 (see FIG. 9).

As shown in FIG. 3, the protruding side surfaces of the pair of protrusions 36 have a shape forming a partial cylindrical inner surface having a common central axis with the relief terminal 20. As shown in FIG. Therefore, a columnar space is provided for handling a tool used for tightening the fastening member fastened to the rescue terminal 20 .

Further, around the rescue terminal 20 in the housing 10 (more specifically, the frame 11), in order to protect the rescue terminal 20, a clamping portion 30 (more specifically, a clamping wall 31) is continuously provided. A peripheral wall portion 40 is provided so as to surround the sides of the relief terminal 20 . In this example, as shown in FIG. 3 , the peripheral wall portion 40 includes a first portion 41 located on the opposite side of the clamping portion 30 with respect to the rescue terminal 20 and extending in the predetermined direction parallel to the clamping portion 30 , and a clamping portion 41 . A pair of second portions 42 extending from both ends of the wall 31 in the predetermined direction toward the rescue terminal 20 in a direction orthogonal to the predetermined direction, and the first portion 41 and the pair of second portions 42 are formed in an arc (rounded chamfer). It has a substantially U-shaped shape consisting of a pair of connecting portions 43 that connect in the shape of a . For this reason, the holding wall 30 and the peripheral wall portion 40 constitute a substantially rectangular frame-like body surrounding the sides of the relief terminal 20 .

The substantially rectangular frame-like body composed of the holding portion 30 (more specifically, the holding wall 31 ) and the peripheral wall portion 40 may be directly (integrally) fixed to the frame 11 . Alternatively, the frame-shaped body may be fixed to the frame 11 by being provided on a part of a member different from the frame 11 and by assembling the separate member to the frame 11 .

A space into which the clip 61 of the booster cable 60 can enter is secured in the second space S2 (see FIGS. 3 and 6) between the first portion 41 of the peripheral wall portion 40 and the relief terminal 20 . Therefore, as shown in FIG. 8, the gripping portion of one clip 61 of the booster cable 60 is engaged with the engaging portion 35 of the clamping portion 30 (cover 32), and the gripping portion of the other clip 61 of the booster cable 60 is locked. By inserting the second space S2, one clip 61 contacts the surface of the holding portion 30 opposite to the relief terminal 20, and the other clip 61 contacts the surface of the relief terminal 20 opposite to the holding portion 30. The rescue terminal 20 and the clamping portion 30 can be clamped by the pair of clips 61 in a normal manner so as to contact the .

In this manner, the rescue terminal 20 and the clamping portion 30 are clamped by the pair of clips 61 in a regular manner, so that the other clip 61 and the rescue terminal 20 are electrically connected. As a result, the booster cable 60 and the battery of the electric vehicle are electrically connected via the rescue terminal 20 and the electric wire 52, so that the battery can be charged using the electric power supplied from the booster cable 60. becomes possible.

On the other hand, as described above, the presence of the pair of projections 36 provided on the cover 32 prevents the clip 61 from entering the first space S1. Therefore, for example, as shown in FIG. 9, the grip portion of the other clip 61 is locked to the side surface of the first portion 41 of the peripheral wall portion 40 opposite to the rescue terminal 20, and the grip portion of the one clip 61 is attached to the first portion 41. Even if an attempt is made to insert the rescue terminal 20 and the first portion 41 of the peripheral wall portion 40 into the pair of clips 61 by inserting them into one space S1, one of the clips 61 may be clipped due to interference with the pair of protrusions 36. cannot be inserted into the first space S1. Therefore, the rescue terminal 20 and the first portion 41 of the peripheral wall portion 40 cannot be clamped by the pair of clips 61 .

Furthermore, in this example, even if an attempt is made to insert the grip portion of the clip 61 into the space between the second portion 42 of the peripheral wall portion 40 and the relief terminal 20, interference with the connecting portion 43 of the peripheral wall portion 40 causes Clip 61 cannot be inserted into the space. Therefore, the rescue terminal 20 and the second portion 42 of the peripheral wall portion 40 cannot be clamped by the pair of clips 61 .

Furthermore, in this example, the second space S2 is the only space in which the gripping portion of the clip 61 can be inserted in the internal space of the frame-like body composed of the holding portion 30 and the peripheral wall portion 40. The clip 61 cannot clamp only the rescue terminal 20 either.

The pair of clips 61 of the booster cable 60 incorporates an elastic member (not shown) that generates a clamping force between the gripping portions of the pair of clips 61 . Due to the characteristics of this elastic member, the gripping force of the pair of clips 61 increases as the distance between the gripping portions of the pair of clips 61 increases. In this example, since the rescue terminal 20 and the clamping portion 30 can be clamped by the pair of clips 61, the distance between the clamping portions of the pair of clips 61 is reduced compared to the mode in which only the rescue terminal 20 is clamped by the pair of clips. becomes wider. As a result, the clamping force of the pair of clips 61 is increased.

Furthermore, since the rescue terminal 20 and the peripheral wall portion 40 (the first portion 41 or the second portion 42 ) cannot be clamped by the pair of clips 61 , the rigidity of the peripheral wall portion 40 is set to the extent that it can withstand the clamping force of the pair of clips 61 . does not need to be very high. Therefore, the rigidity of the peripheral wall portion 40 can be set lower than the rigidity of the holding portion 30 (more precisely, the holding wall 31).

<Action/effect>
As described above, according to the electric connection box 1 according to the embodiment of the present invention, one clip 61 contacts the surface of the clamping portion 30 opposite to the relief terminal 20 , and the other clip 61 clamps the rescue terminal 20 . The relief terminal 20 and the holding portion 30 are held by a pair of clips 61 so as to contact the surface opposite to the portion 30 . For this reason, compared to a mode in which only the rescue terminal 20 is clamped by the pair of clips 61, the gap between the gripping portions of the pair of clips 61 is widened, so the clamping force of the pair of clips 61 is increased. As a result, the pair of clips 61 that clamp the relief terminal 20 are less likely to come off from the relief terminal 20 . In addition, since a pair of protrusions 36 (entry prevention portions) are provided to prevent the clip 61 from entering the first space S1 between the clamping portion 30 and the rescue terminal 20, the first space is closed. It is possible to prevent the clip 61 from being inserted into S1 and only the rescue terminal 20 to be clamped by the pair of clips 61 .

Furthermore, according to the electrical connection box 1, the pair of protrusions 36 form a partial cylindrical inner surface having a common center axis with the relief terminal 20. As shown in FIG. Therefore, it is possible to prevent the clip 61 from entering the first space S1 while securing a columnar space for handling a tool used for tightening the fastening member fastened to the rescue terminal 20 .

Furthermore, according to the electric connection box 1, the rescue terminal 20 can be protected by the peripheral wall portion 40 surrounding the rescue terminal 20 while securing the second space S2 into which the other clip 61 can enter.

Furthermore, according to the electrical junction box 1, when the electrical junction box 1 is mounted on an electric vehicle, the electrical junction box 1 is used with the holding wall 30 covered with the cap 32. As shown in FIG. Thereby, when the clip 61 of the booster cable 60 is connected to the relief terminal 20 , the clip 61 can be prevented from entering the first space S<b>1 between the holding portion 30 and the relief terminal 20 . On the other hand, when the electric junction box 1 is mounted in a normal vehicle other than an electric vehicle (a vehicle in which a battery is mounted in the space under the bonnet), the booster cable 60 can be directly connected to the battery terminal. Since the battery can be charged, there is no need to assume a situation where the clip 61 of the booster cable 60 is connected to the relief terminal 20 . Therefore, the electric connection box 1 can be used with the cap 32 removed from the clamping wall 30 . This makes it possible to share the housing 10 of the electrical connection box 1 between the electric vehicle and the normal vehicle.

Furthermore, according to the electric junction box 1, one clip 61 contacts the surface of the holding portion 30 opposite to the relief terminal 20, and the other clip 61 contacts the surface of the relief terminal 20 opposite to the holding portion 30. When the rescue terminal 20 and the clamping portion 30 are clamped by the pair of clips 61 so as to contact with the clip, the engaging portion 35 of the cap 32 is engaged with one of the clips 61 to prevent the clip from the clamping portion 30 from Omission of 61 can be prevented.

Furthermore, according to the electrical connection box 1, the locking structure (the locking projection 33 of the clamping wall 31 and the locking hole 34 of the cover 32) is provided at the location facing the first space S1 into which the clip 61 cannot enter. Therefore, when the rescue terminal 20 and the clamping portion 30 are clamped by the pair of clips 61, the cap 32 is clamped due to the unlocking of the locking structure due to the contact of the clip 61 to the locking structure. Dropping out of the wall 31 can be prevented.
