Abstract
An electrical connector for mounting to a print circuit board includes an insulative housing, a metal shell shielding around the housing and a plurality of terminals received in the housing. Each terminal having a body section and a contact section extending from the body section, the housing includes a first housing and a second housing, the body section being received in the second housing and the contact section extending from the second housing to the first housing. The first housing has a first dielectric constant and the second housing has a second dielectric constant higher than the first dielectric constant so as to prevent the characteristic impedance change.
Claims17
An electrical connector for mating with a receptacle connector, comprising:
- an insulative housing having a first housing and a second housing received in the first housing;
- a metal shell shielding the insulative housing;
- a plurality of terminals received in the insulative housing and each having a body section and a contact section extending from the body section, each part of the terminal have essentially a same thickness, the contact section adapted to connect with other contacting portions of the receptacle connector so as to result in thereabouts a lower impedance compared with the body section, the body section being received in the second housing and the contact section extending from the second housing to the first housing;
- wherein the first housing has a first dielectric constant and the second housing has a second dielectric constant higher than the first dielectric constant so as to have an impedance of the whole terminal could get balanced when the electrical connector is mating with the receptacle connector.
An electrical connector comprising:
- an insulative housing assembly including a first housing and a second housing discrete from each other;
- a plurality of conductive contacts associated with the housing assembly, each of said contacts including a front mating section, a rear soldering section and a body section therebetween, the mating section and the soldering section adapted to be connected with other external conductive parts so as to result in thereabouts a lower impedance compared with the body section;
- the body section being closer to the second housing than to the first housing, thereby being electrically affected by the second housing more than by the first housing, wherein
- a dielectric constant of said second housing is larger than that of the first housing to compensate impedance difference between the body section and at least one of the mating section and the soldering section;
- and
- each of the plurality of conductive contacts has essentially a same cross-sectional dimension therealong.
An electrical connector comprising:
- an insulative housing assembly including a first housing and a second housing discrete from each other;
- a plurality of contacts disposed in the housing assembly, each of said contacts defining a front mating section, a rear soldering section and a body section therebetween, the front mating section and the rear soldering section being adapted to be joined with other external conductive parts to form a combo cross-section thereby lowering an impedance thereof while the body section not, under condition that the body section is fully intimately surrounded by the second housing while both the front mating section and the rear soldering section are not fully intimately surround by the first housing but in an exposed manner;
- wherein
- an dielectric constant of the second housing is larger than that of the first housing for compensation of dielectric constant difference between the body section and at least one of the front mating section and the rear soldering section;
- and
- each of the plurality of contacts has essentially a same cross-sectional dimension therealong.
