Electric junction box, molding and processing dies therefor

1. An electric junction box, comprising:

a plurality of bus-bars spaced apart from each other; and

a case made of a resin, covering the plurality of bus-bars and including a window for exposing a portion of the plurality of bus-bars;

wherein the window has a first edge, and the respective exposed portions of the plurality of bus-bars extend coplanar with the window and to the first edge, and a second edge located between the respective exposed portions of the plurality of bus-bars; and

the first edge is along a virtual line that is at an angle with respect to an extending direction of the bus-bars, and the second edge is with a depressed area having a shape of a triangle whose slope is the virtual line.

2. The electric junction box according to claim 1 , wherein a connection for connecting the bus-bars is in the respective exposed portions of the plurality of bus-bars, and the connection is disconnected after molding.

3. A processing die, comprising:

a dice and a punch cutting the connection of the electric junction box according to claim 2 ,

wherein the dice has an insert hole configured to come into contact with the exposed portions of the plurality of bus-bars and to permit insertion of the punch at a position of the connection; and

the dice is along the first and second edges.

4. A molding die comprising:

at least an upper die and a lower die configured to integrally mold the plurality of bus-bars which are configured to form an electrical circuit, to a base member of the case made of the resin of the electric junction box according to claim 1 ;

wherein a frame portion forming the window for exposing portions of the plurality of bus-bars spaced apart from each other in the base member is on the at least one of the upper and lower dies;

an edge of the frame portion corresponding to an edge of the window includes a first edge located at a depressed area enclosing the respective bus-bars and a second edge located at a raised portion located between the respective bus-bars;

the first edge is along a virtual line that is at an angle with respect to an extending direction of the bus-bars; and

the second edge is on a lateral surface of the frame portion in a shape of a triangle that takes the virtual line as a slope and that is raised on the lateral surface of the frame portion.

5. The electric junction box according to claim 1 , wherein the triangle is divided from a rectangular area between at least two of the plurality of bus-bars,

the triangle is divided from the rectangle by the virtual line, which is an oblique line of the rectangle, along the angle,

the rectangular area without the triangle is within the window, and

the triangle is outside of the window.

6. The electric junction box according to claim 1 , wherein a direction in which the first edge extends is along the virtual line.

7. The electric junction box according to claim 1 , each of the plurality of bus-bars within the window is spaced apart, along the slope, from each other of the plurality of bus-bars, and

each of the plurality of bus-bars has a same longitudinal length.
