Benefits of technology

This solution streamlines the detachment process by allowing both casings to be removed synchronously with the bolt, enhancing operational efficiency and ensuring secure, synchronized detachment without leaving one casing fixed, even with a single central bolt.

Problems solved by technology

This subsequent insertion of the bolt B presents a parts administration problem.

Embodiment Construction

[0037]FIG. 1 is a schematic diagram showing an upper casing 10, a lower casing 11 and a holder 20. The upper casing 10 and the lower casing 11 are coupled lockingly together beforehand and are fixed to the holder 20 by engaging a bolt B with a nut N embedded in or fixed on the holder 20. Of course, the casings 10, 11 could be fixed to a vehicle body panel or other such fixing member instead of the holder 20. Additionally, the terms upper and lower are used herein for a convenient frame of reference and are not intended to imply a required gravitational orientation.

[0038] Bolt mounting portions 13, 14 are provided in substantially central portions of an upper wall 10b of the upper casing 10 and a bottom wall 11b of the lower casing 11. The bolt B is held rotatably in the bolt mounting portions 13, 14. An impact wrench (not shown) can be inserted through a bolt hole 10c in the substantially central portion of the upper wall 10b of the upper casing 10 to turn a head Ba of the bolt B. ...

Abstract

Upper and lower casings (10, 11) have the surrounding walls coupled together. A bolt (B) is mounted beforehand in the casings (10, 11), and projects through a bolt hole (11c) in the lower casing (11) to fix the casings (10, 11) to a holder (20). A first bush (15) is fixed in the lower casing (11) and a second bush (16) is interlocked with an outer circumferential surface of the first bush (15). The bolt (B) passes through the bushes (15, 16) so that a lower surface of the bolt head (Ba) engages the upper end surface of the first bush (15). On the other hand, an inward-projection is formed on an upper part of the second bush (16), and contacts the upper surface of the bolt head (Ba). Thus, the bolt head (Ba) is held rotatably between the upper end surface of the first bush (15) and the inward-projection.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The invention relates to an automotive electrical connection box. [0003] 2. Description of the Related Art [0004] JP 10-302887 and FIG. 6 herein disclose an automotive electrical connection box. With reference to FIG. 6, the electrical connection box has lower and upper casings 1, 2 with surrounding walls that are lockingly coupled together with a lower cover 3. Connectors 4 are provided on the lower cover 3. A bolt B is introduced through the casings 1, 2 and is screwed into a bolt inserting portion 5 in the middle of connectors 4 in the lower cover 3. Thus, the casings 1, 2 are locked together and are fixed to the lower cover 3. [0005] The bolt B can be unthreaded to release the casings 1, 2 from the lower cover 3. However, the casings 1, 2 are not raised automatically and detached from the lower cover 3 as the bolt B is unthreaded. Rather, an operator has to detach the casings 1, 2 from the lower cover 3 after th...
