Description

本発明は、電気自動車の電源配線を中継する中継コネクタに関するものである。   The present invention relates to a relay connector that relays power wiring of an electric vehicle.

電気自動車やハイブリッド車等では、インバータから高電圧の交流電力が高圧ハーネスを介して各種電気機器に供給される。インバータは、バッテリーから供給される直流電圧を所要の高電圧に変換して、各種電気機器に供給する。   In an electric vehicle, a hybrid vehicle, or the like, high-voltage AC power is supplied from an inverter to various electric devices via a high-voltage harness. The inverter converts a DC voltage supplied from the battery into a required high voltage and supplies it to various electric devices.

図６に示すように、インバータ１から例えば暖房機２及びエアコン３に高電圧電源を供給する場合に、中継コネクタ４が介在されることがある。このような構成では、インバータ１からＰ極電線５ａとＮ極電線６ａからなる高圧ハーネス７を介して中継コネクタ４に高電圧電源が供給される。そして、中継コネクタ４からそれぞれ高圧ハーネス８，９を介して暖房機２及びエアコン３に高電圧電源が供給される。   As shown in FIG. 6, when a high voltage power supply is supplied from the inverter 1 to, for example, the heater 2 and the air conditioner 3, the relay connector 4 may be interposed. In such a configuration, high voltage power is supplied from the inverter 1 to the relay connector 4 via the high voltage harness 7 including the P pole wire 5a and the N pole wire 6a. Then, a high voltage power supply is supplied from the relay connector 4 to the heater 2 and the air conditioner 3 through the high voltage harnesses 8 and 9, respectively.

高圧ハーネス８はＰ極電線５ｂとＮ極電線６ｂを備え、高圧ハーネス９はＰ極電線５ｃとＮ極電線６ｃを備えている。
このような構成により、インバータ１に接続される高圧ハーネスの本数を削減して、インバータ１の小型化が図られている。 The high-voltage harness 8 includes a P-pole wire 5b and an N-pole wire 6b, and the high-voltage harness 9 includes a P-pole wire 5c and an N-pole wire 6c.
With such a configuration, the number of high-voltage harnesses connected to the inverter 1 is reduced, and the inverter 1 is reduced in size.

図７に示すように、中継コネクタ４内では接続ターミナル１０に３本のＰ極電線５ａ〜５ｃの接続端がかしめ固定されている。同様に、３本のＮ極電線６ａ〜６ｃも共通の接続ターミナルにかしめ固定されている。   As shown in FIG. 7, the connection ends of the three P-pole wires 5 a to 5 c are caulked and fixed to the connection terminal 10 in the relay connector 4. Similarly, the three N-pole wires 6a to 6c are also caulked and fixed to a common connection terminal.

そして、インバータ１から高圧ハーネス７を介して中継コネクタ４に供給される高電圧電源は、中継コネクタ４から高圧ハーネス８，９を介して暖房機２及びエアコン３に供給される。   The high voltage power supplied from the inverter 1 to the relay connector 4 via the high voltage harness 7 is supplied from the relay connector 4 to the heater 2 and the air conditioner 3 via the high voltage harnesses 8 and 9.

なお、上記従来技術に関連する先行文献として、特許文献１，２が知られている。   Note that Patent Documents 1 and 2 are known as prior documents related to the above-described prior art.

Need to be caulked and fixed to the connection terminal 10 respectively.

従って、かしめ作業を６か所で行う必要があって、組み立て工数が増大するとともに、かしめ位置の間隔をかしめ作業の作業性を損なわないような間隔とすると、中継コネクタ４の筐体が大型化するという問題点がある。   Accordingly, it is necessary to perform the caulking work at six places, and the number of assembling steps increases, and if the distance between the caulking positions is set so as not to impair the workability of the caulking work, the casing of the relay connector 4 is enlarged. There is a problem of doing.

（第一の実施形態）
この実施形態の中継コネクタとインバータ及び暖房機、エアコン等の機器を接続する構成は、図６と同様であり、同一構成部分は同一符号を付して説明する。 (First embodiment)
The configuration for connecting the relay connector of this embodiment to the inverter, the heater, the air conditioner, and the like is the same as that shown in FIG.

図１は、インバータから供給される高電圧電源を、例えば２台の機器に供給する中継コネクタ内でのＰ極電線の接続構造を示す。
Ｐ極電線を構成する主電線１１ａの中間部には、被覆を剥がして内部の芯線を露出させた接続部１２が形成されている。Ｐ極電線を構成する分岐電線１１ｂの端部にも被覆を剥がして芯線を露出させた接続部１３が形成されている。そして、接続部１２，１３がかしめ金具１４でかしめられて、電気的に接続されている。 FIG. 1 shows a connection structure of P-pole wires in a relay connector that supplies high-voltage power supplied from an inverter to, for example, two devices.
A connecting portion 12 is formed in the middle portion of the main electric wire 11a constituting the P-pole electric wire by peeling off the coating and exposing the inner core wire. A connecting portion 13 is also formed on the end portion of the branch wire 11b constituting the P-pole wire by peeling off the coating and exposing the core wire. And the connection parts 12 and 13 are caulked with the caulking metal fitting 14, and are electrically connected.

図２に示すように、かしめ金具１４は導電性を備えた銅等の金属でＬ字状に形成されるとともに、その両端部に断面Ｖ字状のかしめ片１５ａ，１５ｂが形成されている。そして、かしめ片１５ａに接続部１２をかしめ固定し、かしめ片１５ｂに接続部１３をかしめ固定すると、主電線１１ａと分岐電線１１ｂが電気的に接続される。   As shown in FIG. 2, the caulking metal fitting 14 is formed in an L shape with a metal such as copper having conductivity, and caulking pieces 15a and 15b having a V-shaped cross section are formed at both ends thereof. When the connecting portion 12 is caulked and fixed to the caulking piece 15a and the connecting portion 13 is caulked and fixed to the caulking piece 15b, the main electric wire 11a and the branch electric wire 11b are electrically connected.

Ｎ極電線に関しても、主電線１１ａと分岐電線１１ｂと同様な構成で電気的に接続される。
次に、上記のように構成された中継コネクタの作用を説明する。 The N-pole wire is also electrically connected with the same configuration as the main wire 11a and the branch wire 11b.
Next, the operation of the relay connector configured as described above will be described.

主電線１１ａの一方の端部１６ａをインバータ１に接続し、他方の端部１６ｂをエアコン３に接続する。かしめ金具１４で主電線１１ａに接続された分岐電線１１ｂの端部１６ｃを暖房機２に接続する。Ｎ極電線も同様にしてその端部をインバータ１、エアコン３及び暖房機２に接続する。   One end 16 a of the main electric wire 11 a is connected to the inverter 1, and the other end 16 b is connected to the air conditioner 3. The end 16c of the branch wire 11b connected to the main wire 11a by the caulking metal fitting 14 is connected to the heater 2. Similarly, the end of the N-pole wire is connected to the inverter 1, the air conditioner 3, and the heater 2.

すると、インバータ１から中継コネクタのＰ極電線である主電線１１ａと分岐電線１１ｂ及びＮ極電線を介してエアコン３及び暖房機２に高電圧電源が供給される。
上記のような中継コネクタでは、次に示す効果を得ることができる。 Then, high voltage power is supplied from the inverter 1 to the air conditioner 3 and the heater 2 via the main electric wire 11a, the branch electric wire 11b, and the N pole electric wire which are P pole electric wires of the relay connector.
With the relay connector as described above, the following effects can be obtained.

（１）かしめ金具１４でＰ極電線及びＮ極電線で２カ所ずつのかしめ作業を行うことにより、インバータ１から２つの機器への高電圧電源の供給を中継する中継コネクタの主電線１１ａと分岐電線１１ｂ及びＮ極電線を接続することができる。従って、図７に示す従来例に比して、かしめ箇所をＰ極電線とＮ極電線で２カ所ずつに削減することができるので、かしめ不良の発生確率を低減して、中継コネクタの動作信頼性を向上させることができる。   (1) Branching with the main wire 11a of the relay connector that relays the supply of the high-voltage power from the inverter 1 to the two devices by performing the caulking work at two places with the P pole wire and the N pole wire with the caulking bracket 14 The electric wire 11b and the N-pole electric wire can be connected. Therefore, as compared with the conventional example shown in FIG. 7, the number of caulking locations can be reduced to 2 at each of the P pole wire and the N pole wire, so that the probability of occurrence of caulking failure is reduced and the operation reliability of the relay connector is reduced. Can be improved.

（２）かしめ金具１４は、Ｌ字状に形成されて、接続部１２，１３をかしめ片１５ａ，１５ｂでかしめる位置は、主電線１１ａの長手方向に若干ずれるとともに、かしめ方向ｆ１，ｆ２も互いに直交する方向となる。従って、図７に示す従来例に比して、かしめ治具の挿入が容易となり、かしめ位置の距離を確保する必要もないので、中継コネクタの筐体を小型化することができる。   (2) The caulking metal fitting 14 is formed in an L shape, and the positions where the connecting portions 12 and 13 are caulked by the caulking pieces 15a and 15b are slightly shifted in the longitudinal direction of the main electric wire 11a, and the caulking directions f1 and f2 are also The directions are orthogonal to each other. Therefore, as compared with the conventional example shown in FIG. 7, the insertion of the caulking jig is facilitated, and it is not necessary to secure the distance of the caulking position, so that the case of the relay connector can be reduced in size.

（第二の実施形態）
図３は、第二の実施形態を示す。この実施形態の主電線１１ａと分岐電線１１ｂは、第一の実施形態と同様な構成である。そして、分岐電線１１ｂの接続部１３を直角方向に屈曲して主電線１１ａの接続部１２に沿わせ、この状態でかしめ金具１７で接続部１２，１３をかしめ固定する。すなわち、かしめ金具１７により主電線１１ａの接続部１２に分岐電線１１ｂの接続部１３を１カ所でかしめ固定して主電線１１ａと分岐電線１１ｂとを電気的に接続した。Ｎ極電線も同様に接続する。 (Second embodiment)
FIG. 3 shows a second embodiment. The main electric wire 11a and the branch electric wire 11b of this embodiment are the same structures as 1st embodiment. And the connection part 13 of the branch electric wire 11b is bent in a right angle direction, and it follows the connection part 12 of the main electric wire 11a, and the connection parts 12 and 13 are caulked and fixed with the caulking fitting 17 in this state. That is, the connecting portion 13 of the branch wire 11b is caulked and fixed at one location to the connection portion 12 of the main wire 11a by the caulking metal fitting 17 to electrically connect the main wire 11a and the branch wire 11b. Connect the N pole wires in the same way.

このような構成により、Ｐ極電線とＮ極電線の双方において主電線１１ａと分岐電線１１ｂが電気的に接続されて、インバータ１からエアコン３及び暖房機２に高電圧電源を中継して供給する中継コネクタが構成される。   With such a configuration, the main wire 11a and the branch wire 11b are electrically connected in both the P-pole wire and the N-pole wire, and the high voltage power supply is relayed and supplied from the inverter 1 to the air conditioner 3 and the heater 2. A relay connector is configured.

上記のような中継コネクタでは、次に示す効果を得ることができる。
（１）かしめ金具１７で１カ所のかしめ作業を行うことにより、インバータ１から２つの機器への高電圧電源の供給を中継する中継コネクタの主電線１１ａと分岐電線１１ｂを接続することができる。従って、図７に示す従来例に比して、かしめ箇所をＰ極電線とＮ極電線で１カ所ずつに削減することができるので、かしめ不良の発生確率を低減して、中継コネクタの動作信頼性を向上させることができる。 With the relay connector as described above, the following effects can be obtained.
(1) By performing the caulking operation at one place with the caulking metal fitting 17, the main electric wire 11a and the branch electric wire 11b of the relay connector for relaying the supply of the high voltage power source from the inverter 1 to the two devices can be connected. Therefore, as compared with the conventional example shown in FIG. 7, the number of caulking locations can be reduced by one for each of the P-pole wire and the N-pole wire, so that the probability of occurrence of caulking failure is reduced and the operation reliability of the relay connector is reduced. Can be improved.

（２）また、かしめ治具の挿入が容易となり、かしめ位置の距離を確保する必要もないので、中継コネクタの筐体を小型化することができる。
（第三の実施形態）
図４及び図５は、第三の実施形態を示す。この実施形態の主電線１１ａと分岐電線１１ｂは、第一の実施形態と同様な構成である。 (2) Further, since the caulking jig can be easily inserted and it is not necessary to secure the distance of the caulking position, the relay connector housing can be miniaturized.
(Third embodiment)
4 and 5 show a third embodiment. The main electric wire 11a and the branch electric wire 11b of this embodiment are the same structures as 1st embodiment.

かしめ金具１８は、導電性を有する金属パイプでＴ字型に一体成型され、直線状に連通して主電線１１ａを挿通可能とした主パイプ１９ａと、主パイプ１９ａの中間部から主パイプ１９ａに交差（ここでは直交）する方向に延びる分岐パイプ１９ｂとを備えている。   The caulking metal fitting 18 is a metal pipe having conductivity and is integrally formed in a T-shape, and is connected to the main pipe 19a from a middle pipe 19a through which the main electric wire 11a can be inserted in a straight line. And a branch pipe 19b extending in a direction intersecting (here, orthogonal).
