Electrical connector and method of manufacture
View Patent ↗An apparatus and method are disclosed for manufacturing an electrical connector. A mold is presented having a pair of opposing dies that each define a mold pocket. The mold pockets of each die can be joined to form a mold cavity. Plastic can be injection molded into the mold cavity to form an electrical connector housing.
1. An electrical connector comprising:
an insulative connector housing that defines two contact-receiving openings; and
two electrically conductive contacts, each of the two electrically conductive contacts received in a respective one of the two contact-receiving openings and each of the two electrically conductive contacts retained in the respective contact-receiving opening by an interference fit created between the insulative connector housing and the two electrically conductive contacts,
wherein if at least one of the two electrical contacts produces an electrically conductive shaving as it is inserted into the respective contact-receiving opening, the respective contact-receiving opening retains the electrically conductive shaving.
2. The electrical connector as recited in claim 1 , wherein the two contact-receiving openings each define an upper contact-portion, a lower contact-portion, and a middle portion, and the upper and lower contact portions are configured to receive the electrically conductive shaving.
3. The electrical connector as recited in claim 1 , wherein each of the two contact-receiving openings are sized greater than the respective electrically conductive contacts.
4. The electrical connector as recited in claim 3 , wherein each of the two contact receiving openings includes a portion that is defined by a side wall that is outwardly sloped along a direction toward one of a respective top and bottom wall of the connector housing.
5. The electrical connector as recited in claim 4 , wherein the electrically conductive contacts extend vertically, and each of the side walls defines an angle with respect to the respective one of the electrically conductive contacts.
6. The electrical connector as recited in claim 5 , wherein the angle has a lower end between and including 0° and 5°, and an upper end between and including 1° and 20°.
7. The electrical connector as recited in claim 6 , wherein each of the portions defines a shape of a frustum.
8. The electrical connector as recited in claim 7 , wherein the portions each comprises an upper portion of the two respective contact-receiving openings, wherein each of the two contact receiving openings further defines a lower contact-portion and a middle portion, and the upper and lower contact portions are configured to receive the electrically conductive shaving.
9. The electrical connector as recited in claim 3 , wherein each of the two contact receiving openings includes a portion that is defined by a side wall that is outwardly curved along a direction toward one of a respective top and bottom wall of the connector housing.
10. The electrical connector as recited in claim 9 , wherein the portions each comprises an upper portion of the two respective contact-receiving openings, wherein each of the two contact receiving openings further defines a lower contact-portion and a middle portion, and the upper and lower contact portions are configured to receive the electrically conductive shaving.
11. The electrical connector as recited in claim 10 , wherein each of the lower portions is defined by a side wall that is outwardly curved along a direction from the middle portion toward the lower wall of the connector housing.
12. The electrical connector as recited in claim 3 , wherein each of the two contact receiving openings includes a portion that is defined by a side wall that extends parallel to the respective electrically conductive contact.
13. The electrical connector as recited in claim 12 , wherein the portions each comprises an upper portion of the two respective contact-receiving openings, wherein each of the two contact receiving openings further defines a lower contact-portion and a middle portion, and the upper and lower contact portions are configured to receive the electrically conductive shaving.
14. The electrical connector as recited in claim 13 , wherein each of the lower portions is defined by a side wall that is outwardly curved along a direction from the middle portion toward the lower wall of the connector housing.
15. The electrical connector as recited in claim 1 , wherein the connector housing is defined by a mold that is configured to receive injection-molded plastic, the mold including:
a die defining a first mold pocket and comprising a first base and a post extending from the first base and disposed in the first mold pocket;
a complementary die defining a second mold pocket and comprising a second base and a post receptor extending from the second base and disposed in the second mold pocket,
wherein the post receptor defines an outer surface that flares inwardly along a direction from a lower end of the post receptor toward the an upper end of the post receptor, and
wherein the die and the complementary die are configured to be joined so as to define a mold cavity.
16. The electrical connector as recited in claim 1 , wherein the connector housing is defined by a mold that is configured to receive injection-molded plastic, the mold comprising:
a die defining a first mold pocket configured to be joined with a complementary die having a second mold pocket so as to define a mold cavity; and
a contact receptor extending from the die inside the first mold pocket, the contact receptor including a contact receptor body defining a lower terminal end, an upper terminal end disposed opposite the lower terminal end, and a contact-receiving aperture extending into the contact receptor body, wherein the lower terminal end has a cross-sectional dimension greater than that of the upper terminal end.
