Description

本発明は、複数の連鎖端子と、それら連鎖端子が配置されたホルダと、2以上の連鎖端子を互いに導通接続する導通部品と、を備える電気接続箱に関する。 TECHNICAL FIELD The present invention relates to an electric connection box including a plurality of chain terminals, a holder in which the chain terminals are arranged, and a conducting part that electrically connects two or more chain terminals to each other.

従来から、車両に搭載されるリレーボックス等のように、リレーやヒューズ等の電子部品を収容するためのホルダを内部に有する電気接続箱が提案されている(例えば、特許文献1を参照)。この種の電気接続箱では、一般に、ホルダに内蔵されたバスバと、電装品等の外部負荷に繋がる電線と、がリレー等の電子部品を介して接続されるようになっている。換言すると、ホルダ内に張り巡らされるように配置されたバスバにリレー等の電子部品が取り付けられ(即ち、電気的に接続され)、バスバと電子部品とが導通されるようになっている。 2. Description of the Related Art Conventionally, an electric connection box has been proposed, such as a relay box mounted on a vehicle, which has a holder inside for housing electronic components such as relays and fuses (see, for example, Patent Document 1). In this type of electrical connection box, generally, a bus bar built in a holder is connected to an electric wire connected to an external load such as an electrical component via an electronic component such as a relay.

ところで、電気接続箱の内部構造等によっては、一部又は全部の電子部品に対して、バスバを用いずに電力供給用の電線及び端子から直接的に電力を供給する場合がある。この場合、そのような電線とバッテリ等の外部電源との接続のために複数の電線をボンダで接合して束ねる処理を容易にするべく、複数の電子部品を取り付け可能な連鎖端子を用いることが考えられる。しかし、単一の連鎖端子で多種多様な製品仕様に対応することが困難である等の理由から、実際には、複数の連鎖端子をホルダに配置せざるを得ない場合がある。この場合、複数の連鎖端子に繋がる複数の電線に対してボンダによる接合処理を施すことになる。即ち、連鎖端子を用いたとしても、ボンダによる接合処理を排除できない場合があり、ボンダによる接合処理の更なる容易化を図る余地がある。 By the way, depending on the internal structure of the electrical junction box, power may be supplied directly from power supply wires and terminals to some or all of the electronic components without using busbars. In this case, a chain terminal to which a plurality of electronic components can be attached can be used in order to facilitate the process of joining and bundling a plurality of wires with a bonder for connecting such wires to an external power source such as a battery. Conceivable. However, because it is difficult to meet a wide variety of product specifications with a single chain terminal, there are cases where a plurality of chain terminals must actually be arranged in the holder. In this case, a plurality of electric wires connected to a plurality of chain terminals are bonded by a bonder. That is, even if chain terminals are used, there are cases where the bonding process using a bonder cannot be eliminated, and there is room for further facilitating the bonding process using a bonder.

本発明は、上述した事情に鑑みてなされたものであり、その目的は、複数の連鎖端子をホルダに配置しながらボンダによる接合処理を容易化できる電気接続箱を提供することにある。 SUMMARY OF THE INVENTION The present invention has been made in view of the circumstances described above, and an object of the present invention is to provide an electric connection box that facilitates bonding processing by a bonder while arranging a plurality of chain terminals in a holder.

前述した目的を達成するために、本発明に係る電気接続箱は、下記[1]~[2]を特徴としている。

In order to achieve the above object, an electric connection box according to the present invention is characterized by the following [1] to [2].
[1]
An electric junction box comprising a holder having chain terminals arranged at a plurality of locations to which a plurality of electronic components can be attached, and a conductive component for electrically connecting two or more of the chain terminals to each other,
each of the plurality of chain terminals,
a plurality of terminal portions to which the electronic component can be attached; a connecting portion that connects the plurality of terminal portions so as to connect them; and a wire connecting portion to which a wire can be connected;
The one chain terminal to which the electric wire is to be connected to the electric wire connecting portion, and the electric wire which is not connected to the electric wire connecting portion and is conductively connected to the one chain terminal via the conducting part. and the other chain terminals form a series of electrical circuits,
Must be an electric junction box.
[2]
In the electrical junction box described in [1] above,
The conductive component is
Having a contact portion having a shape that can be conductively connected to the terminal portion of the chain terminal,
Must be an electric junction box.

上記[1]の構成の電気接続箱によれば、ホルダに複数の連鎖端子を配置するとともに、導通部品を用いて2以上の連鎖端子(即ち、複数の連鎖端子の全て又は一部)を互いに導通接続する。これにより、2以上の連鎖端子と導通部品による一連の電気回路が構成される。よって、導通接続された2以上の連鎖端子のうちの任意の一つの電線接続部に電力供給用の電線を接続すれば、導通部品を介して他の連鎖端子に電力が供給されるため、連鎖端子の全てに電線を接続する必要がない。換言すると、導通部品を用いない場合に比べ、連鎖端子に接続するべき電線の本数を低減できる。その結果、ボンダによる接合処理を容易化できる。例えば、全ての連鎖端子が導通部品で互いに導通接続されれば、1本の電線のみで全ての連鎖端子に電力を供給することができるため、接合処理を完全に排除することができる。なお、一般的なバスバに代えて連鎖端子を用いることで、例えば、バスバに比べて様々な製品仕様に容易に対応し得る点でメリットがある。このように、本構成の電気接続箱は、複数の連鎖端子をホルダに配置しながらボンダによる接合処理を容易化できる。 According to the electrical connection box having the configuration [1] above, a plurality of chain terminals are arranged in the holder, and two or more chain terminals (that is, all or part of the plurality of chain terminals) are connected to each other using a conductive part. Conductive connection. As a result, a series of electric circuits is formed by two or more chain terminals and conductive parts. Therefore, if a power supply wire is connected to any one of the two or more electrically connected chain terminals, the electric power is supplied to the other chain terminals via the conductive parts. There is no need to connect wires to all terminals. In other words, the number of electric wires to be connected to the chain terminal can be reduced compared to the case where no conductive parts are used. As a result, the bonding process using a bonder can be facilitated. For example, if all the chain terminals are conductively connected to each other with a conductive part, only one electric wire can supply power to all the chain terminals, so that the joining process can be completely eliminated. By using chain terminals instead of general busbars, for example, there is an advantage in that various product specifications can be easily accommodated compared to busbars. In this manner, the electric connection box of this configuration can facilitate the bonding process using a bonder while arranging a plurality of chain terminals in the holder.

上記[2]の構成の電気接続箱によれば、導通部品が、連鎖端子の端子部に導通接続可能な形状を有する接点部を有する。よって、本来は電子部品を取り付けるための連鎖端子の端子部を、導通部品との接続のために兼用することができる。これにより、導通部品との接続のための専用の接点箇所を連鎖端子に設ける場合に比べ、連鎖端子の構造のシンプル化が可能である。更に、汎用品の連鎖端子を用いることで製造コストの低減を図ることもできる。 According to the electrical connection box having the configuration [2], the conductive component has the contact portion having a shape that allows conductive connection to the terminal portion of the chain terminal. Therefore, the terminal portion of the chain terminal, which is originally used to attach the electronic component, can also be used for connection with the conductive component. As a result, the structure of the chain terminal can be simplified as compared with the case where the chain terminal is provided with a dedicated contact point for connection with the conductive component. Furthermore, the manufacturing cost can be reduced by using general-purpose chain terminals.

このように、本発明によれば、複数の連鎖端子をホルダに配置しながらボンダによる接合処理を容易化できる電気接続箱を提供できる。 As described above, according to the present invention, it is possible to provide an electrical connection box that facilitates the bonding process using a bonder while arranging a plurality of chain terminals in a holder.

4本の端子片42のうち前側の2本の端子片42と後側の2本の端子片42との前後方向の間隔は、前後方向に隣接する収容部11の前後方向の間隔と等しい。4本の端子片42のうち左側の2本の端子片42と右側の2本の端子片42との左右方向の間隔は、左右一対の収容部11に収容された一対のヒューズ20の内側の端子片21同士の左右方向の間隔と等しい。更に、4本の端子片42のうち左側の2本の端子片42の各々の形状は、左右一対の収容部11のうち左側の収容部11に収容されたヒューズ20の内側の端子片21の形状と同じであり、4本の端子片42のうち右側の2本の端子片42の各々の形状は、左右一対の収容部11のうち右側の収容部11に収容されたヒューズ20の内側の端子片21の形状と同じである。 Of the four terminal strips 42 , the two front terminal strips 42 and the two rear terminal strips 42 are spaced from each other in the front-rear direction at the same interval as the accommodating portions 11 adjacent to each other in the front-rear direction. Of the four terminal strips 42 , the left two terminal strips 42 and the right two terminal strips 42 are spaced in the left-right direction by the distance between the pair of fuses 20 housed in the pair of left and right housing portions 11 . It is equal to the horizontal interval between the terminal strips 21 . Further, the shape of each of the left two terminal strips 42 among the four terminal strips 42 is similar to that of the inner terminal strip 21 of the fuse 20 accommodated in the left accommodating portion 11 of the pair of left and right accommodating portions 11 . The shape of each of the right two terminal strips 42 out of the four terminal strips 42 is the same as the shape of the fuse 20 accommodated in the right accommodating portion 11 of the pair of left and right accommodating portions 11 . It has the same shape as the terminal piece 21 .

以上のことから、導通部品40は、図2に示すように、前後方向に隣接する任意の左右二対の(4つの)収容部11の内側領域に、4本の端子片42を上方からそれぞれ挿入することで、ホルダ10に装着可能となっている。ホルダ10に導通部品40が装着された状態では、4つの端子片42の各々は、対応する収容部11に位置する連鎖端子30の端子部31と電気的に接続される。このように、本来はヒューズ20の端子片21を接続するための連鎖端子30の端子部31が、導通部品40との接続のためにも使用される。 From the above, as shown in FIG. 2, the conductive component 40 is formed by attaching four terminal strips 42 from above to the inner regions of arbitrary two pairs (four) of housing portions 11 adjacent to each other in the front-rear direction. It can be attached to the holder 10 by inserting it. When the holder 10 is mounted with the conductive component 40 , each of the four terminal strips 42 is electrically connected to the terminal portion 31 of the chain terminal 30 positioned in the corresponding housing portion 11 . In this way, the terminal portion 31 of the chain terminal 30 originally for connecting the terminal piece 21 of the fuse 20 is also used for connection with the conductive component 40 .

図2に示す例では、3つの収容部11Aのうち後側の収容部11A以外の2つの収容部11A、3つの収容部11Bのうち前側の収容部11B以外の2つの収容部11B、3つの収容部11Cのうち後側の収容部11C以外の2つの収容部11C、3つの収容部11Dのうち前側の収容部11D以外の2つの収容部11D(計8つの収容部11)に、それぞれ、ヒューズ20が収容されている。ヒューズ20が収容されている8つの収容部11に対応する8つの外側端子50にそれぞれ接続された8本の電線9が、ホルダ10の外部へ延出している。連鎖端子30A~30Dのうち連鎖端子30Aのみに接続された1本の電線8がホルダ10の外部に延出している。 In the example shown in FIG. 2, two storage portions 11A other than the rear storage portion 11A out of the three storage portions 11A, two storage portions 11B other than the front storage portion 11B out of the three storage portions 11B, and three In the two storage portions 11C other than the rear storage portion 11C among the storage portions 11C, and in the two storage portions 11D other than the front storage portion 11D among the three storage portions 11D (a total of eight storage portions 11), A fuse 20 is housed therein. Eight electric wires 9 connected to eight outer terminals 50 corresponding to the eight housing portions 11 in which the fuses 20 are housed extend outside the holder 10 . One electric wire 8 connected only to the chain terminal 30A among the chain terminals 30A to 30D extends outside the holder 10. As shown in FIG.

加えて、ヒューズ20が収容されていない4つの収容部11A,11B,11C,11Dのそれぞれの内側領域に、4つの端子片42がそれぞれ挿入されるように、導通部品40が、ホルダ10に装着されている(図6及び図9も参照)。以下、4つの収容部11A,11B,11C,11Dに挿入されている端子片42をそれぞれ、端子片42A、42B,42C,42Dと呼ぶことがある(図3及び図4参照)。 In addition, the conducting component 40 is attached to the holder 10 so that the four terminal strips 42 are inserted into the respective inner regions of the four accommodating portions 11A, 11B, 11C, and 11D where the fuse 20 is not accommodated. (See also FIGS. 6 and 9). Hereinafter, the terminal strips 42 inserted into the four housings 11A, 11B, 11C, and 11D may be called terminal strips 42A, 42B, 42C, and 42D, respectively (see FIGS. 3 and 4).

図2に示すホルダ10の状態では、図10に示すように、4つの連鎖端子30A,30B,30C,30Dの全てが、導通部品40によって互いに導通接続されている。これにより、電線8が接続された1つの連鎖端子30Aと、電線8が接続に接続されず且つ導通部品40を介して連鎖端子30Aと導通接続される3つの連鎖端子30B,30C,30Dと、が一連の電気回路を構成している。この結果、バッテリからの電力は、1本の電線8を介して、8本の電線9(即ち、8つの電装品)にそれぞれ供給され得る。換言すれば、8本の電線9(即ち、8つの電装品)それぞれにバッテリからの電力を供給するために、4つの連鎖端子30A~30Dの全てに電線8を接続する必要がない。このため、導通部品40を用いない場合に比べ、連鎖端子30に接続するべき電線の本数を低減できる。 In the state of the holder 10 shown in FIG. 2, all four chain terminals 30A, 30B, 30C, and 30D are conductively connected to each other by the conductive parts 40, as shown in FIG. As a result, one chain terminal 30A to which the electric wire 8 is connected, three chain terminals 30B, 30C, and 30D that are not connected to the connection of the electric wire 8 and are electrically connected to the chain terminal 30A via the conductive parts 40, form a series of electrical circuits. As a result, power from the battery can be supplied to eight wires 9 (that is, eight electrical components) through one wire 8 . In other words, it is not necessary to connect wires 8 to all four chain terminals 30A-30D in order to supply power from the battery to each of the eight wires 9 (ie, eight electrical components). Therefore, the number of electric wires to be connected to the chain terminal 30 can be reduced as compared with the case where the conductive component 40 is not used.

<作用・効果>
以上、本実施形態に係る電気接続箱1によれば、ホルダ10に複数の連鎖端子30を配置するとともに、導通部品40を用いて2以上の連鎖端子30(即ち、複数の連鎖端子30の全て又は一部)を互いに導通接続する。これにより、2以上の連鎖端子30と導通部品40による一連の電気回路(図10参照)が構成される。よって、導通接続された2以上の連鎖端子30のうちの任意の一つの電線接続部33に電力供給用の電線8を接続すれば、導通部品40を介して他の連鎖端子30に電力が供給されるため、連鎖端子30の全てに電線を接続する必要がない。換言すると、導通部品40を用いない場合に比べ、連鎖端子30に接続するべき電線の本数を低減できる。その結果、ボンダによる接合処理を容易化できる。例えば、本実施形態のように、全ての連鎖端子30が導通部品40で互いに導通接続されれば、1本の電線8のみで全ての連鎖端子30に電力を供給することができるため、接合処理を完全に排除することができる。このように、本実施形態に係る電気接続箱1は、複数の連鎖端子30をホルダ10に配置しながらボンダによる接合処理を容易化できる。
<Action/effect>
As described above, according to the electrical connection box 1 according to the present embodiment, the plurality of chain terminals 30 are arranged in the holder 10, and the two or more chain terminals 30 (that is, all of the plurality of chain terminals 30) are connected by using the conductive parts 40. or part) are conductively connected to each other. As a result, a series of electrical circuits (see FIG. 10) are formed by two or more chain terminals 30 and conductive parts 40 . Therefore, if the electric wire 8 for power supply is connected to any one wire connection portion 33 of the two or more conductively connected chain terminals 30, power is supplied to the other chain terminals 30 through the conductive parts 40. Therefore, it is not necessary to connect wires to all of the chain terminals 30 . In other words, the number of electric wires to be connected to the chain terminal 30 can be reduced compared to the case where the conductive component 40 is not used. As a result, the bonding process using a bonder can be facilitated. For example, as in the present embodiment, if all the chain terminals 30 are conductively connected to each other by the conductive parts 40, since power can be supplied to all the chain terminals 30 with only one electric wire 8, the joining process can be completely eliminated. As described above, the electrical connection box 1 according to the present embodiment can facilitate bonding processing by a bonder while arranging the plurality of chain terminals 30 in the holder 10 .

更に、導通部品40が、連鎖端子30の端子部31に導通接続可能な形状を有する接点部(端子片42)を有する。よって、本来はヒューズ20を取り付けるための連鎖端子30の端子部31を、導通部品40との接続のために兼用することができる。これにより、導通部品40との接続のための専用の接点箇所を連鎖端子30に設ける場合に比べ、連鎖端子30の構造のシンプル化が可能である。更に、汎用品の連鎖端子30を用いることで製造コストの低減を図ることもできる。 Further, the conductive component 40 has a contact portion (terminal piece 42 ) having a shape that allows conductive connection to the terminal portion 31 of the chain terminal 30 . Therefore, the terminal portion 31 of the chain terminal 30 for attaching the fuse 20 can also be used for connection with the conductive component 40 . Thereby, the structure of the chain terminal 30 can be simplified as compared with the case where the chain terminal 30 is provided with a dedicated contact point for connection with the conductive component 40 . Furthermore, the manufacturing cost can be reduced by using the general-purpose chain terminal 30 .
