Electrical connector
View Patent ↗An electrical connector for connecting with an electrical card comprises a plurality of signal terminal modules and at least one ground terminal. Each of the plurality of signal terminal modules having a pair of signal terminal and an insulation body. Each of the pair of signal terminals include a first contact portion, a first securing portion, and a first connection portion positioned between the first contact portion and the first securing portion. The insulation body is overmolded to each first connection portion of the pair of signal terminals. The ground terminal includes a pair of second contact portions, a second securing portion, and a second connection portion positioned between the pair of second contact portions and the second securing portion. The insulation body includes openings positioned to correspond to each of the pair of signal terminals, with a portion of each of the pair of signal terminals is exposed.
1. An electrical connector for connecting with an electrical card, comprising:
a plurality of signal terminal modules, each of the plurality of signal terminal modules comprising:
a pair of signal terminals, each of the pair of signal terminals having a first contact portion, a first securing portion, and a first connection portion positioned between the first contact portion and the first securing portion; and
an insulation body overmolded to each first connection portion of the pair of signal terminals; and
a ground terminal having a pair of second contact portions, a second securing portion, and a second connection portion positioned between the pair of second contact portions and the second securing portion;
wherein the insulation body includes openings formed along a front surface and a back surface of the insulation body and corresponding to each of the pair of signal terminals so that a portion of each of the pair of signal terminals is exposed to ambient air;
wherein the plurality of signal terminal modules are arranged in a front to back arrangement and the openings along the back surface of the insulation body of a front one of two adjacent signal terminal modules are staggered with the openings positioned along the front surface of the insulation body of a rear one of the two signal terminal modules positioned adjacent to each other.
2. The electrical connector according to claim 1 , wherein each first contact portion is hook shaped.
3. The electrical connector according to claim 2 , wherein a contact point of each first contact portion is positioned at a vertex of an arc section adjacent to a free end of the first contact portion.
4. The electrical connector according to claim 1 , wherein a width of each signal terminal gradually narrows from the first securing portion to the first contact portion.
5. The electrical connector according to claim 1 , wherein the ground terminal is a symmetrical structure.
6. The electrical connector according to claim 5 , wherein the pair of second contact portions are positioned symmetrically along both sides of a center line splitting the ground terminal.
7. The electrical connector according to claim 6 , wherein the second securing portion is positioned along the center line splitting the ground terminal.
8. The electrical connector according to claim 7 , wherein the second securing portion is positioned parallel with each first securing portion of the pair of signal terminals.
9. The electrical connector according to claim 8 , further comprises an insulation housing.
10. The electrical connector according to claim 9 , wherein each first securing portion and the second securing portion extend through a bottom surface of the insulation housing.
