Abstract

A method of forming a part includes uni-directionally injecting a mold with material to form a molded part, removing the molded part from the mold, and forming at least one cavity in the molded part, the at least one cavity being defined by a machining process separate from a molding process.

First claim

What is claimed is:

1. A method of forming a receptacle connector, comprising:
uni-directionally injecting a mold with material to form a molded part, wherein a primary flow direction of the material during the injecting is substantially parallel to a top surface and a bottom surface of the molded part, and substantially orthogonal to a front surface and a back surface of the molded part;
removing the molded part from the mold;
forming a cavity in the molded part by removing a central region of the molded part so as to define an inner surface, wherein the removing forms a front opening within the front surface and a back opening within the back surface, wherein a width of the front opening, as defined in a first direction parallel to the front surface, is greater than a distance in the first direction between the inner surface and the top surface, and greater than a distance in the first direction between the inner surface and the bottom surface; and
populating the cavity with electrical contacts such that the receptacle connector can electrically connect with a corresponding plug via the front opening or the back opening.

2. The method of claim 1 , wherein the molded part includes at least one protrusion that is configured to engage with a fastener.

3. The method of claim 1 , further comprising preparing the mold for the uni-directional injecting by performing at least one of:
cleaning the mold;
surface treatment of mold surfaces of the mold; and
assembly of the mold.

4. The method of claim 1 , wherein the material includes fibers such that the fibers are oriented substantially parallel to the top surface and the bottom surface and substantially orthogonal to the front surface and the back surface.

5. The method of claim 1 , wherein the electrical contacts are configured to severably connect with the corresponding plug.

6. The method of claim 1 , wherein the molded part is a seamless part.

7. A method of forming a receptacle connector, comprising:
forming a molded part by injecting a plastic material through a mold cavity in a primary direction toward a central region of the molded part, the primary direction during the injecting causing fibers within the plastic material to be oriented generally parallel to a top surface and a bottom surface of the molded part, and generally orthogonal to a front surface and back surface of the molded part;
removing the molded part from the mold cavity;
forming a cavity in the molded part by removing the central region of the molded part so as to define an inner surface, wherein the removing forms a front opening within the front surface and a back opening within the back surface, wherein a width of the front opening, as defined in a first direction parallel to the front surface, is greater than a distance in the first direction between the inner surface and the top surface, and greater than a distance in the first direction between the inner surface and the bottom surface; and
assembling an electrical connector within the cavity such that the receptacle connector can be electrically coupled with a corresponding plug via the front opening or the back opening.

8. The method of claim 7 , further comprising preparing the mold cavity to receive the plastic material, wherein preparing the mold cavity comprises at least one of:
cleaning the mold cavity; and
surface treatment of mold surfaces of the mold cavity.

9. The method of claim 7 , wherein the orientation of the fibers is related to a directional stiffness of the receptacle connector.

10. The method of claim 9 , wherein the electrical connector is configured to severably connect with the corresponding plug.

11. The method of claim 7 , wherein the molded part is a seamless part.

12. The method of claim 7 , wherein injecting the plastic material through the mold cavity comprises:
uni-directionally injecting the plastic material through a single gate region.

13. The method of claim 12 , wherein the single gate region is arranged on the front surface or the back surface.

14. The method of claim 7 , wherein the plastic material is injected through a single gate region.

15. The method of claim 7 , wherein removing the molded part is facilitated by compressed air.
