Abstract

An electrical connector includes a number of first contacts and a number of second contacts, an insulative housing, a shielding plate, and a metallic shell. The insulative housing has a base portion, a tongue portion, and a number of receiving grooves running through the base portion to the tongue portion. The tongue portion defines a first surface and a second surface. The receiving grooves are exposed on the first surface and the second surface. The insulative housing, the second contacts, and the shielding plate are insert-molded to form a contact module, and the first contacts are assembled to the receiving grooves.

First claim

What is claimed is:

1. An electrical connector comprising:
a plurality of contacts having a plurality of first contacts and a plurality of second contacts, each first contact having a first engaging section and each second contact having a second engaging section;
an insulative housing having a base portion, a tongue portion extending forwardly from the base portion, and a plurality of receiving grooves running through the base portion to the tongue portion in a front-and-rear direction, the tongue portion defining a first surface and a second surface opposite to the first surface in an up-and-down direction perpendicular to the front-and-rear direction, the receiving grooves exposed in the first surface and the second surface in the up-and-down direction; and
a metallic shielding plate located between the first engaging sections and the second engaging sections; wherein
the insulative housing, the second contacts, and the shielding plate are integrally formed together to form a contact module via an insert-molding process, while the first contacts are forwardly assembled to the receiving grooves once the contact module is formed; wherein
the first contacts are exposed upon the first surface and the second contacts are exposed upon the second surface; and
the base portion defines a plurality of slots connecting with the receiving grooves in the up-and-down direction and exposed to an exterior in the up-and-down direction.

2. The electrical connector as claimed in claim 1 , further comprising an insulative member molded to a rear end of the contact module with the first contacts for fastening the first contacts.

3. The electrical connector as claimed in claim 2 , wherein the insulative member includes a covering portion that fills the slots along the up-and-down direction and the receiving grooves along the front-and-rear direction.

4. The electrical connector as claimed in claim 3 , wherein said insulative member presses the first contacts in the up-and-down direction.

5. The electrical connector as claimed in claim 1 , wherein the insulative housing defines a through hole extending therethrough in the up-and-down direction, and the shielding plate defines a plurality of openings aligned with the through hole in the up-and-down direction so as to remove corresponding bridges which are originally respectively linked between every two neighboring second contacts and located in the through hole for facilitating said insert-molding process to form said contact module while being punched out once the contact module has been formed.

6. The electrical connector as claimed in claim 5 , further comprising an insulative member molded to a rear end of the contact module with the first contacts for fastening the first contacts, wherein said insulative member fills the through hole and the corresponding openings.

7. The electrical connector as claimed in claim 6 , wherein said through hole is formed around a root section of the tongue portion.

8. An electrical connector comprising:
a plurality of contacts having a plurality of first contacts and a plurality of second contacts, each first contact having a first engaging section and a first soldering section, and each second contact having a second engaging section and the second soldering section;
an insulative housing having a base portion, a tongue portion extending forwardly from the base portion, and a plurality of receiving grooves running through the base portion to the tongue portion in a front-and-rear direction, the tongue portion defining a first surface and a second surface opposite to the first surface in an up-and-down direction perpendicular to the front-and-rear direction, the receiving grooves exposed in the first surface and the second surface in the up-and-down direction;
a metallic shielding plate located between the first engaging sections and the second engaging sections; wherein
the insulative housing, the second contacts, and the shielding plate are integrally formed together to form a contact module via an insert-molding process, while the first contacts are assembled to the insulative housing once the contact module is formed; wherein
the engaging sections of the first contacts are exposed upon the first surface and the engaging sections of the second contacts are exposed upon the second surface; wherein
the first soldering sections of the first contacts and the second soldering sections of the second contacts are aligned in one line along a transverse direction perpendicular to both said front-and-rear direction and said up-and-down direction;
the insulative housing defines a through hole extending therethrough in the up-and-down direction, and the shielding plate defines a plurality of openings aligned with the through hole in the up-and-down direction so as to remove corresponding bridges which are originally respectively linked between every two neighboring second contacts and located in the through hole for facilitating said insert-molding process to form said contact module while being punched out once the contact module has been formed; and
an insulative member molded to the contact module with the first contacts for fastening the first contacts and filling the through hole.

9. The electrical connector as claimed in claim 8 , wherein each of said first contacts further includes a first connecting section linked between the first engaging section and the first soldering section and disposed within the housing, each of said second contacts further includes a second connecting section linked between the second engaging section and the second soldering section and disposed in the housing, and the first connecting sections are straight while the second connecting sections are bent.

10. The electrical connector as claimed in claim 8 , wherein the first engaging sections of the first contacts have unequal intervals between every adjacent two first engaging sections, the second engaging section of the second contacts have unequal intervals between every adjacent two second engaging sections while a combination of the aligned first soldering sections and second soldering sections have equal intervals between every adjacent two first soldering sections and second soldering sections.

11. An electrical connector comprising:
a plurality of contacts having a plurality of first contacts and a plurality of second contacts, each first contact having a first engaging section and each second contact having a second engaging section;
an insulative housing having a base portion, a tongue portion extending forwardly from the base portion, and a plurality of receiving grooves running through the base portion to the tongue portion in a front-and-rear direction, the tongue portion defining a first surface and a second surface opposite to the first surface in an up-and-down direction perpendicular to the front-and-rear direction, the receiving grooves exposed in the first surface and the second surface in the up-and-down direction;
a metallic shielding plate located between the first engaging sections and the second engaging sections, wherein the insulative housing, the second contacts, and the shielding plate are integrally formed together to form a contact module via an insert-molding process and the first contacts are forwardly assembled to the receiving grooves after the contact module is formed; and
an insulative member molded to a rear end of the contact module with the first contacts for fastening the first contacts; wherein
the first contacts are exposed upon the first surface and the second contacts are exposed upon the second surface;
the insulative housing defines a through hole extending therethrough in the up-and-down direction, and th
