Abstract
Abstract An electrical connector ( 1 ) includes an insulative housing ( 10 ) defining a mating port ( 11 ) and a number of passageways ( 14 ) communicating with the mating port, and a number of contacts ( 20 ) received in the passageways of the insulative housing. Each of the contacts includes a retention portion ( 21 ) retained in a corresponding passageway of the insulative housing, a resilient arm ( 22 ) extending from the retention portion, an abutting portion ( 23 ) abutting against an inner wall ( 17 ) of the corresponding passageway for pre-loading the contact, and a contact portion ( 24 ) extending from the abutting portion and exposed into the mating port of the insulative housing. The abutting portion is deflectable away from the inner wall of the corresponding passageway together with the contact portion.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
257 words
An electrical connector, comprising: an insulative housing defining a mating port and a pluruality of passageways communicating with the mating port; and a plurality of contacts received in the passageways of the insulative housing, each of the contacts comprising a retention portion retained in a corresponding passageway, a resilient arm extending from the retention portion, an abutting portion extending from the resilient arm and abutting against an inner wall of the corresponding passageway for pre-loading the contact, and a contact portion extending from the abutting portion and exposed into the mating port, the abutting portion being deflectable away from the inner wall together with the contact portion; wherein the insulative housing defines a corresponding number of apertures communicating with the mating port and the passageways, and wherein each of the contacts comprises a distal end bent from the contact portion and received in a corresponding aperture; wherein the insulative housing defines a pair of slots in opposite sides of each of the passageways for receiving the retention portion of the contact; wherein each of the contacts comprise a tail portion extending from the retention portion beyond the insulative housing for being soldered to a mother board; wherein the inner wall of the corresponding passageway is formed with a clump pressing the abutting portion of the contact; wherein the insulative housing defines a central line in a mating direction thereof, wherein the passageways are symmetrically arranged at opposite sides of the central line in pairs, and wherein the contacts are symmetrically received in the pairs of the passageways.
Claim 2
Dependent Claim
257 words
An electrical connector, comprising: an insulative housing defining a mating port and a pluruality of passageways communicating with the mating port; and a plurality of contacts received in the passageways of the insulative housing, each of the contacts comprising a retention portion retained in a corresponding passageway, a resilient arm extending from the retention portion, an abutting portion extending from the resilient arm and abutting against an inner wall of the corresponding passageway for pre-loading the contact, and a contact portion extending from the abutting portion and exposed into the mating port, the abutting portion being deflectable away from the inner wall together with the contact portion; wherein the insulative housing defines a corresponding number of apertures communicating with the mating port and the passageways, and wherein each of the contacts comprises a distal end bent from the contact portion and received in a corresponding aperture; wherein the insulative housing defines a pair of slots in opposite sides of each of the passageways for receiving the retention portion of the contact; wherein each of the contacts comprise a tail portion extending from the retention portion beyond the insulative housing for being soldered to a mother board; wherein the inner wall of the corresponding passageway is formed with a clump pressing the abutting portion of the contact; wherein the insulative housing defines a central line in a mating direction thereof, wherein the passageways are symmetrically arranged at opposite sides of the central line in pairs, and wherein the contacts are symmetrically received in the pairs of the passageways.
Claim 3
Dependent Claim
226 words
An electrical connector assembly, comprising: an electrical connector comprising: an insulative housing defining a mating port and a plurality of pairs of passageways symmetrically arranged on opposite sides of and in communication with the mating port; and a plurality of pairs of contacts symmetrically received in the pairs of the passageways of the insulative housing, each of the contacts comprising an abutting portion abutting against an inner wall between each of pairs of the passageways for pre-loading the contact, and a contact portion extending from the abutting portion and exposed into the mating port of the insulative housing; and a complementary component comprising an insulative mating portion, and a plurality of conductors disposed on opposite sides of the mating portion; wherein when the electrical connector mates with the complementary component, the mating portion of the complementary component is inserted into the mating port of the electrical connector, the conductors of the complementary component press against the contact portions of the contacts of the electrical connector for deflecting the contact portions and to separate the abutting portions away from the inner walls between the pairs of the passageways; wherein the inner wall of the corresponding passageway is formed with a clump pressing the abutting portion of the contact; wherein the complementary component comprises a housing defining a cavity partially receiving the insulative housing of the electrical connector.
Claim 4
Dependent Claim
226 words
An electrical connector assembly, comprising: an electrical connector comprising: an insulative housing defining a mating port and a plurality of pairs of passageways symmetrically arranged on opposite sides of and in communication with the mating port; and a plurality of pairs of contacts symmetrically received in the pairs of the passageways of the insulative housing, each of the contacts comprising an abutting portion abutting against an inner wall between each of pairs of the passageways for pre-loading the contact, and a contact portion extending from the abutting portion and exposed into the mating port of the insulative housing; and a complementary component comprising an insulative mating portion, and a plurality of conductors disposed on opposite sides of the mating portion; wherein when the electrical connector mates with the complementary component, the mating portion of the complementary component is inserted into the mating port of the electrical connector, the conductors of the complementary component press against the contact portions of the contacts of the electrical connector for deflecting the contact portions and to separate the abutting portions away from the inner walls between the pairs of the passageways; wherein the inner wall of the corresponding passageway is formed with a clump pressing the abutting portion of the contact; wherein the complementary component comprises a housing defining a cavity partially receiving the insulative housing of the electrical connector.
