Abstract

An electrical connector (100) includes an insulative housing (1), and a number of contacts received therein. The contacts include a pair of first and second grounding contacts (212, 222), and a pair of first and second signal contacts (211, 221). Each of the first signal and grounding contacts includes a first contact portion (213), a first mounting portion (214), a first horizontal portion (215), and a first connecting portion (216). Each of the second signal and grounding contacts includes a second contact portion (223), a second mounting portion (224), and a second horizontal portion (225). A first distance (d1) between the first connecting portion and the second mounting portion is greater than a second distance (d2) between the first and second horizontal portions, and is also greater than a third distance (d3) between the first and second mounting portions.

Claims17

Dependent claims

An electrical connector comprising:

an insulative housing;
and
a plurality of contacts received in the insulative housing, the contacts comprising a pair of first grounding contacts for transmitting grounding signal, a pair of first signal contacts for transmitting a differential signal, a pair of second grounding contacts for transmitting grounding signal, and a pair of second signal contacts for transmitting a differential signal, the first grounding contacts and the first signal contacts arranged in a first row along a first direction, the first signal contacts disposed between the first grounding contacts, the second grounding contacts and the second signal contacts arranged in a second row along the first direction, the second signal contacts disposed between the second grounding contacts, the second row is spaced apart from the first row along a second direction perpendicular to the first direction, each of the first signal contacts and the first grounding contacts comprising a first contact portion for being mated with a plug connector, a first mounting portion for being mounted on an outer printed circuit board, a first horizontal portion extending rearwardlly from the first mating portion, and a first connecting portion connected between the first horizontal portion and the first mounting portion, each of the second signal contacts and the second grounding contacts comprising a second contact portion for being mated with the plug connector, a second mounting portion for being mounted on the outer printed circuit board, and a second horizontal portion extending rearwardlly from the second mating portion;
wherein
a first distance between the first connecting portion and the second mounting portion is greater than a second distance between the first horizontal portion and the second horizontal portion, and is also greater than a third distance between the first mounting portion and the second mounting portion.

2 more elements

An electrical connector comprising:

an insulative housing body forming a receiving room exposed to an exterior in a horizontal direction for receive a mating connector;
four rows of contacts retained in the housing body including a row of upper outer contacts, a row of upper inner contacts, a row of lower outer contacts and a row of lower inner contacts where the upper outer contacts and the lower outer contacts have corresponding contacting points located in front of those of the upper inner contacts and the lower inner contacts, and the upper outer contacts and the upper inner contacts have the corresponding contacting points on an upper side of the receiving room while the lower outer contacts and the lower inner contacts have the corresponding contacting points on a lower side of the receiving room;
each of the four rows of contacts except the row of lower outer contacts including a deflectable contact portion exposed in the receiving room, a horizontally extending mounting portion exposed outside of the housing body, a horizontal portion connected to a rear end of the contact portion, an obliquely extending connecting portion linked to a rear end of the horizontal portion, and a vertical portion between the mounting portion and the connecting portion;
wherein
each contact of the upper inner row of contacts further includes a horizontal portion linked between the vertical portion and the obliquely extending connecting portion so as to enlarge a distance between the obliquely extending connecting portion of each of the upper outer row of contacts and that of each of the upper inner row of contacts.
