Electrical connection box
View Patent ↗There is provided a downsized electrical connection box in which the reliability of the mechanical connection between blocks provided in the electrical connection box is improved. The electrical connection box 1 includes a plurality of electric components, a first block 3 mounted with the electric components and a second block mounted with the electric components. The first block 3 includes a tubular-shaped first member 32, 33 projecting towards the second block 5 . The second block 5 includes a second member 52, 53 arranged to be slidably inserted into the first member. The first and the second blocks 3, 5 are coupled to each other by slidably inserting the second member 52, 53 into the first member 32, 33 . At least one electric component 8 of the plurality of electric components is received inside the first and the second members 32, 52, 33, 53.
1. An electrical connection box having a plurality of electric components, a first block mounted with electric components and a common electric component and a second block mounted with different electric components and the common electric component, the second block being coupled to the first block, the electrical connection box comprising,
a tubular-shaped first member provided to the first block and projecting towards the second block, and
a second member provided to the second block and arranged to be slidably inserted into the first member, wherein
the first block and the second block are coupled to each other by slidably inserting the second member into the first member, and wherein
the common electric component of the plurality of electric components is received inside the first member and the second member attached to each other.
2. The electrical connection box according to claim 1 , wherein
a first connection member connected to electrical components mounted to the first block and a second connection member connected to the electrical components mounted to the second block are electrically connected to each other via the at least one electric component received inside the first member and the second member attached to each other.
3. The electrical connection box according to claim 1 , wherein
the first member is provided with an arm portion and a first engagement portion projecting from the arm portion towards the second member,
the arm portion being arranged between a pair of slits formed at the first member along a direction of insertion of the second member, and
the second member is provided with a second engagement portion arranged to engage with the first engagement portion of the first member.
4. The electrical connection box according to claim 2 , wherein
the first member is provided with an arm portion and a first engagement portion projecting from the arm portion towards the second member,
the arm portion being arranged between a pair of slits formed at the first member along a direction of insertion of the second member, and
the second member is provided with a second engagement portion arranged to engage with the first engagement portion of the first member.
5. The electrical connection box according to claim 1 , wherein
the tubular-shaped first member is provided at a corner of the first block, and
the second member is provided at a corner of the second block.
6. The electrical connection box according to claim 1 , wherein
the tubular-shaped first member is formed by a continuous series of peripheral walls.
