Abstract

Abstract To make an electrical connection box smaller, lighter and more highly functional by improving internal circuits thereof. A printed circuit board 23 having electronic devices mounted thereon and a busbar 24 are provided as internal circuits to be accommodated in a casing of an electrical connection box. Terminals 24a provided in the busbar 24 are inserted through the printed circuit board 23 to be secured to a conductive portion by solders 30 for a direct electrical connection.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 71 words
An electrical connection box in which at least one printed circuit board (23) having electric and/or electronic devices (22) mounted thereon and at least one busbar (24) are accommodated in substantially different levels in a casing (20; 21), wherein one or more terminals (24b) projecting from the busbar (24) are soldered and/or bonded to a corresponding conductive portion (23b; 23c) of the printed circuit board (23) for a direct electrical connection.
Claim 2
Dependent Claim 63 words
An electrical connection box according to claim 1, wherein an insulating plate (27) is at least partially provided between the printed circuit board (23) and the busbar (24); one or more insulating plate through holes (27a) are formed in the insulating plate (27); and the terminals (24b) projecting from the busbar (24) are inserted or insertable through the insulating plate through holes (27a).
Claim 3
Dependent Claim 50 words
An electrical connection box according to one or more of the preceding claims, wherein one or more board through holes (23d; 23e) are formed in the printed circuit board (23); and the terminals (24b) projecting from the busbar (24) are inserted or insertable through the board through holes (23d; 23e).
Claim 4
Dependent Claim 48 words
An electrical connection box according to claim 3, wherein portions (24b-1) of the terminals (24b) projecting from the board through holes (23d; 23e) of the printed circuit board (23) are soldered and/or bonded to be connected with the conductive portion (23b; 23c) of the printed circuit board (23).
Claim 5
Dependent Claim 53 words
An electrical connection box according to claim 3 or 4, wherein portions (24b-1) of the terminals (24b) projecting from the board through holes (23d; 23e) of the printed circuit board (23) project into one or more connector receptacles formed in the casing (20; 21) so as to be connected to a mating connector.
Claim 6
Dependent Claim 84 words
An electrical connection box according to one or more of the preceding claims, wherein an internal circuit comprising one or more wires (25) and cramping terminals (26) being connected or connectable with the wires (25) at a first end (26a) is further accommodated in a substantially different level in the casing (20; 21), and a second end (26b) of each cramping terminal (26) is soldered and/or bonded to the conductive portion (23b; 23c) of the printed circuit board (23) for a direct electrical connection.
Claim 7
Dependent Claim 44 words
A connector according to claim 6, wherein one or more auxiliary cramping terminals (29) being connected or connectable to the wires (25) project into one or more connector receptacles (35) being provided on the casing (20; 21) for the connection with a mating connector.
Claim 8
Dependent Claim 46 words
A connector according to claim 6 or 7, wherein an internal circuit insulating plate (28) is arranged substantially between the busbar (24) and the internal circuit, the internal circuit insulating plate (28) having terminal holes (28a) for the insertion of the cramping terminals (26; 29) therethrough.
