Abstract

A wire routing device includes a wire housing part, a terminal housing chamber part, and a plurality of wire lead-out parts. The terminal housing chamber part includes a plurality of terminal housing chambers. Each of the wire lead-out parts couples one of the housing grooves with one of the terminal housing chambers. Each of wire surplus length absorption spaces is formed inside of a substantially rectangle abcd defined by a section bc of an outer wall of the voltage detection wire housing part located at a side of the terminal housing chamber and a section ad of a wall of the housing groove which faces the section bc, which are cut by a line ab and a line cd.

Claims

1. A wire routing device for routing wires, and comprising:

a wire housing part;

a terminal housing chamber part; and

a plurality of wire lead-out parts, wherein the wire housing part, the terminal housing chamber part and wire lead-out parts are made of insulative material;

wherein the wire housing part includes a plurality of housing grooves, each of the housing grooves is formed between two elongated walls erected at an interval, the wire housing part is divided at a plurality of places in an extending direction of the wire housing part, and respective ends of the divided housing grooves are coupled with each other by elastic coupling members;

wherein the terminal housing chamber part includes a plurality of terminal housing chambers which are arranged in a first direction, the terminal housing chambers are coupled with each other by elastic coupling members;

wherein each of the terminal housing chambers houses an electrically conductive metal plate which connects a positive terminal of a battery to a negative terminal of an adjacent battery adjacent to the battery;

wherein each of the wire lead-out parts couples one of the housing grooves with one of the terminal housing chambers and has a right side wall and left side wall to lead out a voltage detection wire connected to a voltage detection terminal in the terminal housing chamber to the corresponding housing groove;

wherein the wire housing part has a plurality of wire surplus length absorption spaces;

wherein each of the wire surplus length absorption spaces is formed inside of a substantially rectangular space abcd defined by a section bc of an outer wall of the voltage detection wire housing part located at a side of the terminal housing chamber and a section ad of a wall of the housing groove which faces the section bc, which are cut by a line ab extending from the left side wall of the wire lead-out part in a second direction perpendicular to the first direction, and a line cd extending from a right side wall of a wire lead-out part corresponding to a terminal housing chamber which is adjacent to left side of the terminal chamber corresponding to the wire lead-out part in the second direction; and

wherein at least one of the wires has a surplus portion which is stored in an associated one of the wire surplus length absorption spaces;

wherein adjacent housing grooves are arranged one on top of the other in the second direction such that adjacent housing grooves share at least one elongated wall extending in the extending direction.

2. The wire routing device according to claim 1, wherein a crimping portion is formed so as to be extended from a part of the voltage detection terminal, and an end of the voltage detection wire is crimped by the crimping portion;

and

wherein a round protrusion is provided at a region which is located at a tip end of one of the two elongated walls forming the wire lead-out part and located farther from the terminal housing chamber than the crimping portion.

3. The wire routing device according to claim 1, wherein the surplus portion is loosely stored.

4. The wire routing device according to claim 1, wherein the wire housing part is configured to lead the wires out of a terminal opening of the wire housing part in the second direction.

5. The wire routing device according to claim 1, wherein each of the surplus length absorption spaces is configured to house a surplus length of only a single wire respectively.
