Electric connection block
View Patent ↗The electric connection block includes: a plurality of layers, each layer consisting of a plurality of terminals bent in an L-shape arranged in a line, each terminal having a first end portion for electric connection and a second end portion for connection to a circuit board; an electrically insulating terminal holder including receiving surfaces arranged in a stairs manner, each receiving surface placing a first section of the terminal thereon, and through holes each permitting a second section of the terminal to be inserted therein, the through hole being adjacent to the receiving surface; and a cover which includes hole parts each permitting the first section of the terminal to be inserted therein and joins the terminal holder.
1. An electric connection block comprising:
a plurality of layers, each said layer consisting of a plurality of terminals bent in an L-shape arranged in a line, each said terminal having a first end portion for electric connection and a second end portion for connection to a circuit board;
an electrically insulating terminal holder including receiving surfaces arranged in a stairs manner, each said receiving surface placing a first section of the terminal thereon, and through holes each permitting a second section of each of the plurality of terminals to be inserted therein, said through hole being adjacent to the receiving surface; and
a cover which includes a plurality of hole parts through which the respective first sections of each of the plurality of terminals extend and thereby joining the terminal holder; and
wherein the hole parts are each arranged and configured to position the first end portions for electric connection of the terminals of the respective layers, so that the first end portions can be smoothly securely connected to respective terminals of electric components such as fuses or relays and to respective terminals of connectors.
2. The electric connection block according to claim 1 , wherein the receiving surface is partitioned by partition walls of the terminal holder, a rib is formed crossing the partition wall at a front end of the partition wall, and the first section of the terminal is provided with a concave groove or hole which engages with the rib.
3. The electric connection block according to claim 1 , wherein the through hole of the terminal holder and/or the hole part of the cover is formed in a tapered shape so as to gradually become narrow in an insertion direction of the terminal.
4. The electric connection block according to claim 1 , wherein a rib, which continues to a partition situated between the hole parts of the cover, engages with a groove part situated at a front end of the rib of the terminal holder.
5. The electric connection block according to claim 1 , wherein the first end portions of the terminals are assembled to the terminal holder on a condition that the first end portions are linked by a link belt per layer, wherein the cover is assembled to the terminal holder on a condition that the link belt is cut.
