High voltage junction block and vehicle including the same
View Patent ↗A high voltage junction block includes a block housing accommodating a circuit module distributing high voltage, a bus bar extending from the block housing, and supplying electric power to an electric power supply target body, a sealing member surrounding a circumference of the bus bar, and protecting moisture from flowing into the bus bar and a terminal of the electric power supply target body electrically connected to the bus bar, and a shield plate provided between the block housing and the sealing member, and protecting noise generated from the electric power supply target body from being leaked to the outside.
1 . A high voltage junction block comprising:
a block housing including a circuit module configured to distribute high voltage;
a bus bar extending from the block housing, and configured to supply electric power to an electric power supply target body;
a sealing member surrounding a circumference of the bus bar, and configured to prevent moisture from flowing into the bus bar and a terminal of the electric power supply target body electrically connected to the bus bar; and
a shield plate positioned between the block housing and the sealing member, and configured to prevent noise generated from the electric power supply target body from being leaked to an outside.
2 . The high voltage junction block of claim 1 , further comprising:
a protruding portion protruding from the block housing along the circumference of the bus bar; and
a seating portion formed at an outer periphery of the protruding portion, and on which the sealing member is seated.
3 . The high voltage junction block of claim 2 , wherein the sealing member includes:
a sealing body formed in a shape corresponding to an outer peripheral shape of the protruding portion; and
a sealing protrusion protruding toward the electric power supply target body from the sealing body.
4 . The high voltage junction block of claim 3 , wherein the sealing member is made of a rubber material.
5 . The high voltage junction block of claim 1 , wherein the shield plate includes:
a first part positioned between the block housing and the sealing member;
a second part extending toward the electric power supply target body from an outer periphery of the first part; and
a third part extending from an outer periphery of the second part, and being in contact with the electric power supply target body.
6 . The high voltage junction block of claim 5 , wherein the third part is tilted at a set angle toward the electric power supply target body, and is in contact with the electric power supply target body by elastic transformation.
7 . The high voltage junction block of claim 5 , wherein a plurality of embosses are formed in the third part.
8 . The high voltage junction block of claim 5 , wherein the shield plate is made of a metallic material which is elastically transformable.
9 . A vehicle comprising:
an inverter including an inverter housing having a first circuit module driving a motor therein, and a terminal formed in the inverter housing; and
a high voltage junction block including a block housing having a second circuit module configured to distribute high voltage, a bus bar extending from the block housing, and electrically connected to the terminal, a sealing member surrounding a circumference of the bus bar, and configured to prevent moisture from flowing into the bus bar and the terminal, and a shield plate positioned between the block housing and the sealing member, and configured to prevent noise generated from the inverter from being leaked to an outside.
10 . The vehicle of claim 9 , further comprising:
a protruding portion protruding from the block housing along a circumference of the bus bar; and
a seating portion formed at an outer periphery of the protruding portion, and on which the sealing member is seated.
11 . The vehicle of claim 10 , wherein the sealing member includes:
a sealing body formed in a shape corresponding to an outer peripheral shape of the protruding portion; and
a sealing protrusion protruding toward an electric power supply target body from the sealing body.
12 . The vehicle of claim 11 , wherein the sealing member is made of a rubber material.
13 . The vehicle of claim 11 , wherein the sealing member is in contact with the inverter housing.
14 . The vehicle of claim 9 , wherein the shield plate includes:
a first part positioned between the block housing and the sealing member;
a second part extending toward the inverter from an outer periphery of the first part; and
a third part extending from an outer periphery of the second part, and being in contact with the inverter housing.
15 . The vehicle of claim 14 , wherein the shield plate is elastically transformable.
16 . The vehicle of claim 14 , wherein the third part is tilted at a set angle toward the inverter housing, and is in contact with the inverter housing by elastic transformation.
17 . The vehicle of claim 14 , wherein a plurality of embosses are formed in the third part.
