At the same time, the cover 91 is brought into contact with the top of the protruding portion 83 to cover a part of the opening of the routing portion 8.
  • the cover 91 covers the opening of the routing part 8 with the cover 91 covering the opening of the routing part 8. Since the contact area between the routing portion 8 and the cover 91 is reduced, the voltage detection line 5 is generated between the routing portion 8 and the cover 91. Can be suppressed.
  • the locking portion 94 is held at a position away from the opening of the routing portion 8. Since the locking force of the locking portion 94 to the locking receiving portion 84 is not directly applied to the contact portion between the routing portion 8 and the cover 91 by being locked by the locking portion 84, the cover 91 is connected to the routing portion 8. The voltage detection line 5 can be pushed into the routing portion 8 by bending the cover 91 so as to create a gap. Thus, the assembly of the bus bar module 1 is completed.
  • the bus bar module 1 assembled in the above-described procedure is overlaid on the upper surface of the battery assembly 2, and the opening on the base wall 7B side of the case 6, the through hole 3a of the bus bar 3, and the through hole 4a of the voltage detection terminal 4 are inserted.
  • the nuts are screwed into the positive electrode 22 and the negative electrode 23, and the electrodes 22, 23, the bus bar 3, and the voltage detection line 5 of the battery 20 are electrically connected, and the assembly of the power supply device 10 is completed.
  • the protruding portion 83 is formed to protrude from the routing portion 8, but the present invention is not limited to this.
  • the protruding portion 83 may be formed to protrude from the cover 91.
  • the shape of the protrusion part 83 was formed in the semicircle shape formed so that the dimension of the arrow Y direction may become small gradually toward the cover 91, this invention is not limited to this. . As long as it is formed so that the dimension in the arrangement direction (arrow Y direction) becomes gradually smaller toward the cover 91, it may be triangular, and the shape is arbitrary.
  • the rotation part 9 was rotatably connected with the opening edge part of each bus bar accommodating part 7 via the hinge 90, this invention is not limited to this.
  • the rotating part 9 may be formed separately from each bus bar accommodating part 7. In that case, the hinge 90 may be omitted.
  • locking part 94 and the latching receiving part 84 were shifted and provided in the sequence direction Y side of the protrusion part 83, this invention is not limited to this.
  • the locking portion 94 and the locking receiving portion 84 may be provided at positions where the protruding portion 83 is aligned in the arrow X direction.
  • rising part 93 (an example of a "connection part") were formed in L shape, this invention is not limited to this.

Abstract

L'invention a pour objectif de fournir un module de barres omnibus et un dispositif d'alimentation électrique permettant d'empêcher l'encombrement de fils conducteurs câblés à l'intérieur d'une partie câblage. Un module de barres omnibus (1) est équipé : d'une pluralité de barres omnibus (3) dans lesquelles des électrodes de batteries adjacentes parmi une pluralité de batteries (20) placées de sorte que chaque électrode (22, 23) est alignée sur une droite, sont connectées entre elles, permettant ainsi de connecter en série cette pluralité de batteries ; de bornes (4) connectées à chaque barre omnibus ; et de boîtiers (6) admettant la pluralité de barres omnibus et la pluralité de bornes. Dans les boîtiers, sont agencés : la partie câblage (8) en forme de gouttière agencée suivant une direction de câblage des batteries, et câblant les fils conducteurs (5) connectés aux bornes selon une direction d'alignement (Y) ; et un couvercle (91) recouvrant l'ouverture de la partie câblage. Une partie saillie (83) formée en saillie par rapport à un côté partie câblage ou couvercle, et allant au contact de l'autre côté, est agencée entre la partie câblage et le couvercle.
