Abstract

An electrical connector (1) includes a dielectric housing (12), a number of first and second terminals (20, 30) received in the dielectric housing respectively and a spacer (25) assembled onto the dielectric housing. Each terminal comprises a contact portion (22, 32) adapted for engaging with a complementary connector and an intermediate portion (21, 31) extending from the contact portion. The intermediate portion (21) of the first terminal is insert-molded in the spacer. The intermediate portion (31) of the second terminal is sandwiched between the dielectric housing and the spacer.

Claims

1. An electrical connector comprising:

a dielectric housing;

a plurality of first and second terminals received in the dielectric housing, each terminal comprising a contact portion adapted for engaging with a complementary connector and an intermediate portion extending from the contact portion; and

a spacer assembled onto the dielectric housing, the intermediate portions of the first terminals being insert-molded in the spacer, the intermediate portions of the second terminals being sandwiched between the dielectric housing and the spacer,

wherein the dielectric housing defines a cavity receiving the spacer therein, and

wherein the dielectric housing defines a plurality of passageways communicating with the cavity, and wherein the intermediate portion of the second terminal is received in a corresponding passageway.

2. The electrical connector as claimed in claim 1, wherein the spacer is formed with a plurality of ribs received in corresponding passageways.

3. The electrical connector as claimed in claim 1, wherein the dielectric housing defines a hole in the inside wall of the cavity, and wherein the spacer is formed with a post engaging with the hole of the dielectric housing.

4. The electrical connector as claimed in claim 1, wherein the dielectric housing defines a notch communicating with the cavity, and wherein the spacer is formed with an embossment engaging with the notch.

5. The electrical connector as claimed in claim 1, wherein the dielectric housing is formed with a first stepped portion and the spacer comprises a second stepped portion engaging with the first stepped portion, and wherein each second terminal comprises a third stepped portion extending from the intermediate portion and sandwiched between the first and the second stepped portion.

6. The electrical connector as claimed in claim 5, wherein the first stepped portion is formed with a plurality of bulges and the second stepped portion defines a plurality of cutouts receiving corresponding bulges and the third stepped portions of the second terminals therein.

7. An electrical connector comprising:

a dielectric housing;

a plurality of first and second terminals received in the dielectric housing, each terminal comprising a contact portion adapted for engaging with a complementary connector and an intermediate portion extending from the contact portion;
