Abstract

An electrical connector includes an insulating body having a first insulator and a second insulator, and multiple terminals disposed on the insulating body. A gap space is formed between the first and second insulators. The gap space is filled with air. Each terminal has a mating segment located above the first insulator, a first fixing segment extending downward from the mating segment and insert-molded into the first insulator, a connecting segment extending downward from the first fixing segment and exposed to the gap space, a second fixing segment extending downward from the connecting segment and insert-molded into the second insulator, and a positioning segment extending downward from the second fixing segment and located below the second insulator. The width of the first and second fixing segment is less than the width of at least one of the mating segment, the connecting segment and the positioning segment.

First claim

What is claimed is:

an insulating body, comprising a first insulator and a second insulator, the first insulator and the second insulator having a gap space therebetween, and the gap space being filled with air; and
a plurality of terminals disposed on the insulating body,
wherein each of the terminals comprises a mating segment located above the first insulator, a first fixing segment extending downward from the mating segment and insert-molded into the first insulator, a connecting segment extending downward from the first fixing segment and exposed to the gap space, a second fixing segment extending downward from the connecting segment and insert-molded into the second insulator, and a positioning segment extending downward from the second fixing segment and located below the second insulator;
wherein each of a width of the first fixing segment and a width of the second fixing segment is less than a width of at least one of the mating segment, the connecting segment and the positioning segment; and
wherein a first transition segment with increasing width extends from each of two ends of the first fixing segment, a first linear segment further extends from each of the first transition segments, the two first linear segments are respectively connected with the mating segment and the connecting segment, a width of the first linear segment is greater than a width of the first transition segment and the width of the first fixing segment, and a height of the first linear segment insert-molded into the first insulator is greater than 0.01 millimeter (mm).

2. The electrical connector according to claim 1 , further comprising a plurality of through holes disposed respectively through the first insulator and/or the second insulator, and each of the through holes located between two adjacent terminals.

3. The electrical connector according to claim 1 , further comprising a plurality of through holes disposed respectively through the first insulator and/or the second insulator, wherein the terminals are arranged in two rows, and one of the through holes is located between any two adjacent terminals in the same row.

4. The electrical connector according to claim 1 , wherein a second transition segment with increasing width extends from each of two ends of the second fixing segment, a second linear segment further extends from each of the second transition segments, the two second linear segments are respectively connected with the positioning segment and the connecting segment, a width of the second linear segment is greater than a width of the second transition segment and the width of the second fixing segment, and a height of the second linear segment insert-molded into the second insulator is greater than 0.01 mm.

5. The electrical connector according to claim 1 , wherein the width of the first fixing segment and the width of the second fixing segment are both less than the width of the connecting segment.

6. The electrical connector according to claim 1 , wherein the width of the mating segment is greater than that of the first fixing segment.

7. The electrical connector according to claim 1 , wherein the width of the positioning segment is greater than that of the second fixing segment.

8. The electrical connector according to claim 1 , wherein the first insulator and the second insulator are disposed separately.

9. The electrical connector according to claim 1 , wherein the insulating body further comprises a third insulator connecting the first insulator and the second insulator, and the first insulator, the second insulator and the third insulator are integrally formed and enclose the gap space.
