ELECTRICAL JUNCTION BOX

摘要

The present invention provides an electrical junction box capable of preventing breakage of a wire member led out to the outside a box body. A control electric wire has a length dimension that is equal to the sum of a routing length for routing an electric wire member composed of the control electric wire and a control connector along the route of an electric wire guiding portion that guides the electric wire member down to a connector retaining portion, and an extra mating length for fitting the control connector in the connector retaining portion. By the control electric wire slackened by an amount equal to the excessive mating length, the control electric wire abuts against a blocking wall continuing to a first outside surface that is provided so as to face a fixing target.

主权项

1. An electrical junction box comprising:
an electrical component;
a casing body for accommodating the electrical component, the casing body affixed to a fixing target and made of insulation resin; andan electric wire member connected to the electrical component and led out to the outside of the casing body, whereinthe electric wire member is configured to include an electric wire portion connected to the electrical component and a connector connected to a tip of the electric wire portion and retained at outside of the casing body, whereinthe casing body is formed to include a first outer surface potion facing the fixing target, a second outer surface potion provided in an inner position that is further apart from the fixing target than the first outer surface potion, an accommodation portion accommodating the electrical component, a connector retaining portion which has the connector fitted therein to retain the connector, an electric wire guiding portion that guides the electric wire member from the accommodation portion to the connector retaining portion, and a blocking wall portion continuing to the first outer surface potion and capable of abutting against the electric wire portion, whereinthe electric wire guiding portion is formed to include a first lead-out portion which leads the electric wire member out from the accommodation portion, a second lead-out portion provided at the second outer surface potion and leading the electric wire member out to the outside of the electrical junction box, a first guiding portion which guides the electric wire member led out to the outside of the electrical junction box to the connector retaining portion, and a second guiding portion provided at a fitting-direction-rearward side in the connector retaining portion, the second guiding portion being capable of abutting against the electric wire portion, wherein the electric wire portion has a length dimension that is equal to a sum of a routing length required to be routed along a route of the electric wire guiding portion and an excessive mating length required to have the connector fitted in the connector retaining portion, and wherein the electric wire portion which slackens by the excessive mating length between the second lead-out portion and the first guiding portion, abuts against the blocking wall portion so as to restrict a protrusion of the electric wire portion further toward the fixing target side than the first outer surface potion.
