The recesses are provided separately. For this reason, since the space for providing a locking piece and a recessed part is needed for each, there existed a problem that it was difficult to miniaturize a wiring module.

A detection terminal for detecting a state of the power storage element, and an insulation protector to which the connection member and the detection terminal are attached. The insulation protector locks the connection member and the connection member. A first locking portion that locks the detection terminal that is stacked on the connection member, and a second locking portion that locks the detection terminal that is stacked on the connection member.
　上記の構成によると、接続部材を係止するための部材と、検知端子を係止するための部材とを兼用することができる。この結果、配線モジュールを小型化することができる。 According to the above configuration, the member for locking the connection member and the member for locking the detection terminal can be used together. As a result, the wiring module can be reduced in size.
　本明細書に開示された技術の実施態様としては以下の態様が好ましい。 The following embodiments are preferred as embodiments of the technology disclosed in this specification.
　前記検知端子は前記蓄電素子の電圧を検知するための電圧検知端子であることが好ましい。 The detection terminal is preferably a voltage detection terminal for detecting the voltage of the storage element.

According to said structure, a detection terminal is piled up on the 1 pole connection member connected to one electrode terminal, and a detection terminal is latched by a 1st latching | locking part and a 2nd latching | locking part, and 1 pole The connecting member can be attached to the insulation protector. Thus, the technique described in this specification is effective when applied to a one-pole connection member connected to one electrode terminal.

（実施形態の作用、効果）
　続いて、本実施形態の作用、効果について説明する。本実施形態によれば、１極用接続部材２１Ａを１極用保持部５１に係止するための部材と、電圧検知端子４３を１極用保持部５１に係止するための部材とを、１極用第１係止部５６によって兼用することができる。また、２極用接続部材２１Ｂを２極用保持部６１に係止するための部材と、電圧検知端子４３を２極用保持部６１に係止するための部材とを、２極用第１係止部６６によって兼用することができる。この結果、配線モジュール２０を小型化することができる。 (Operation and effect of the embodiment)
Then, the effect | action and effect of this embodiment are demonstrated. According to the present embodiment, the member for locking the one-pole connecting member 21A to the one-pole holding part 51 and the member for locking the voltage detection terminal 43 to the one-pole holding part 51 are: It can be shared by the 1st pole 1st latching | locking part 56. FIG. In addition, a member for locking the two-pole connection member 21B to the two-pole holding portion 61 and a member for locking the voltage detection terminal 43 to the two-pole holding portion 61 are the first for two pole The locking portion 66 can also be used. As a result, the wiring module 20 can be reduced in size.
　また、本実施形態においては、１極用接続部材２１Ａ、及び２極用接続部材２１Ｂには、蓄電素子の電圧を検知するための電圧検知端子４３が重ねられているから、蓄電素子の電圧を検知することができる。 In the present embodiment, the voltage detection terminal 43 for detecting the voltage of the power storage element is overlapped on the one-pole connection member 21A and the two-pole connection member 21B. Can be detected.
　また、本実施形態においては、１つの電極端子１２Ａには１極用接続部材２１Ａが接続されている。 Further, in the present embodiment, a one-pole connection member 21A is connected to one electrode terminal 12A.
　絶縁プロテクタ１４のうち、１つの電極端子１２Ａに接続される１極用接続部材２１Ａが取り付けられる部分には、１つの電極端子１２Ａに対応するスペースしかない。このため、１極用接続部材２１Ａを取り付けるための部材を形成するためのスペースを確保することが困難であった。本実施形態によれば、１つの電極端子１２Ａに接続される１極用接続部材２１Ａに電圧検知端子４３を重ねて、１極用第１係止部５６と１極用第２係止部５７とに電圧検知端子４３を係止することにより、１極用接続部材２１Ａを絶縁プロテクタ１４に取り付けることができる。このように、本明細書に記載された技術は、１つの電極端子１２Ａに接続される１極用接続部材２１Ａに適用すると効果的である。 In the insulating protector 14, a portion to which the one-pole connection member 21A connected to one electrode terminal 12A is attached has only a space corresponding to one electrode terminal 12A. For this reason, it has been difficult to secure a space for forming a member for attaching the one-pole connection member 21A. According to the present embodiment, the voltage detection terminal 43 is overlapped on the one-pole connection member 21A connected to one electrode terminal 12A, and the one-pole first locking portion 56 and the one-pole second locking portion 57 are stacked. By locking the voltage detection terminal 43, the one-pole connection member 21A can be attached to the insulation protector 14.

Thereby, the number of members formed in the wiring module 20 can be reduced as compared with the case where the member for locking the two-pole connection member 21B and the member for locking the voltage detection terminal are provided separately. Thereby, since the space for arrange | positioning a member in the wiring module 20 increases, the freedom degree of the layout of the member in the wiring module 20 can be improved.
