Spacer for harness bundle
A spacer for maintaining one or more wires during a molding process, the spacer having an external frame, and a plurality of spring curved leaves. Each spring curved leaf has a fixed end attached to an inner face of the external frame and a free end. The free ends of the plurality of spring curved leaves are arranged to flexibly wrap the one or more wires.
1. A spacer for maintaining one or more pieces during a molding process, the spacer comprising:
an external frame; and
a plurality of spring leaves, wherein each spring leaf has a fixed end attached to an inner face of the external frame and a free end, wherein the free ends of the plurality of spring leaves are arranged to flexibly wrap the one or more pieces to be maintained, wherein each spring leaf is a spring curved leaf that has, in a rest position, a curvature such that the free end of each curved leaf is configured to contact the one or more pieces to be maintained on a concave side of the curvature or on a convex side of the curvature, wherein each spring curved leaf extends, in the rest position, at an oblique angle from the inner face of the external frame, wherein the number of spring curved leaves is greater or equal to six, and wherein the spring curved leaves are evenly distributed around the inner face of the external frame.
2. The spacer according to claim 1 , wherein the free ends are movable between a first position so as to define a first wrapping portion, and at least a second position, different from the first position, so as to define a second wrapping portion and wherein the first wrapping portion and the second wrapping portion are a plurality of lines of contact or surfaces or thin surfaces of the free ends on the one or more pieces and the difference between the first wrapping portion and the second wrapping portion is that they are placed in different diameters to allow different diameter of the one or more pieces to be held in place.
3. The spacer according to claim 1 , wherein each free end is arranged to be in contact with the one or more pieces to be maintained.
4. The spacer according to claim 1 , wherein the external frame has an external surface and a groove arranged circumferentially on the external surface.
5. The spacer according to claim 1 , wherein the spacer further has a hinged portion and a lock portion preferably opposed to the hinged portion, and wherein the spacer is arranged to define an opened position wherein the one or more pieces to be maintained can be introduced in the spacer, and a closed position wherein the one or more pieces to be maintained can be wrapped by the spacer at a level of the free ends.
6. The spacer according to claim 1 , wherein the spacer further has at least one lock portion.
7. The spacer according to claim 1 , wherein the external frame has at least one outside pin.
8. The spacer according to claim 1 , wherein the spacer comprises six leaves evenly distributed about the inner face of the external frame.
9. The spacer according to claim 1 , wherein the spacer comprises ten leaves evenly distributed about the inner face of the external frame.
10. The spacer according to claim 1 , wherein the spacer comprises twelve leaves evenly distributed about the inner face of the external frame.
11. A method for overmolding one or more pieces to be maintained, the method comprising:
providing at least one spacer having an external frame and a plurality of spring leaves, wherein each spring leaf has a fixed end attached to an inner face of the external frame and a free end, wherein the free ends of the plurality of spring leaves are arranged to flexibly wrap the one or more pieces to be maintained, wherein each spring leaf is a spring curved leaf that has, in a rest position, a curvature such that the free end of each curved leaf is configured to contact the one or more pieces to be maintained on a concave side of the curvature or on a convex side of the curvature, wherein each spring curved leaf extends, in the rest position, at an oblique angle from the inner face of the external frame, wherein the number of spring curved leaves is greater or equal to six, wherein the spring curved leaves are evenly distributed around the inner face of the external frame, and wherein the free ends of the plurality of spring curved leaves are arranged to flexibly wrap the one or more pieces to be maintained;
providing one or more pieces to be maintained;
installing in a mold the at least one spacer, and the one or more pieces to be maintained in contact with free ends of the least one spacer; and
injecting a sealing material in the mold so as to overmold the one or more pieces to be maintained.
12. The method according to claim 11 , further comprising opening the mold so as to extract the one or more overmolded pieces to be maintained.
13. The method according to claim 11 , wherein the external frame of the least one spacer has at least one outside pin and wherein the method further comprises placing the at least one outside pin of the least one spacer in at least one pocket of the mold.
14. The method according to claim 11 , wherein the sealing material is polyurethane.
