Electric connection box
View Patent ↗An electric connection box which can easily attach electric components to an attachment portion of box body. The electric connection box includes a box body having the attachment portion attaching the relay on an upper surface of the box body, and a relay fixed on the box body. The attachment portion includes a tube, a plurality of openings and a plurality of holding portions arranged in the opening. The tube inserts the relay into an inside thereof, and stands from the upper surface. The opening passes through the tube 5 , and is arranged with a space along a circumferential direction of the tube. The holding portion presses the relay toward the inside of the tube, and holds the relay to the tube. The holding portion includes an arm and a protrusion projecting toward the inside of the tube.
1. An electric connection box comprising:
a box body; and
an attachment portion for attaching an electric component on a surface of the box body,
the attachment portion includes a plurality of through holes arranged on the surface of the box body for passing through terminals extending from the electric component, a tube standing from the surface of the box body for receiving the electric component into an inside of the tube, a plurality of openings passing through the tube and arranged with a space along a circumferential direction of the tube, and a plurality of holding portions provided in the openings and holding the electric component to the tube by pressing the electric component into the inside of the tube,
wherein each of the holding portions includes an arm and a protrusion projecting toward the inside of the tube from another end of the arm, one end of the arm continues to an inner edge of the tube away from the surface of the box body, and the other end thereof is formed with a free end; and the holding portions flex outwardly when the electronic component is received into the inside of the tube and is in a final connected state, such that a restoring force of the arm holds the electric component to the tube.
2. The electric connection box as claimed in claim 1 , wherein at least two of the protrusions opposed to each other respectively lock with locking protrusions of the electric component when the electric component is received in the tube.
3. The electric connection box as claimed in claim 1 , wherein the protrusion includes a slope narrowing toward a top of the protrusion at the other end side whereas one end side of the protrusion faces the surface of the box body.
4. The electric connection box as claimed in claim 2 , wherein the protrusion includes a slope narrowing toward a top of the protrusion at the other end side whereas one end side of the protrusion faces the surface of the box body.
