ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to an electrical connector and particularly to an electrical connector having grounding bridges.
2. Description of Related Art
Electrical connectors usually have guiding columns to be inserted into guiding apertures of mating connectors for guiding the electrical connectors to engage with the mating connectors and grounding bridges provided on the guiding columns for making contact with grounding members of the mating connector for Electro-Static Discharge(ESD).
U.S. Pat. No. 6,390,833 discloses in
FIGS. 7 and 8
thereof a connector
10
comprises a pair of metallic grounding pads
17
each providing a contacting portion
174
exposed from opposite ends of the housing
11
for electrically engaging with a shield
23
of a mating connector
20
. The grounding pads
17
are inserted into cavities
128
of the housing
11
from a bottom face of the housing
11
, and the grounding pads
17
are positioned in the cavities
128
by junctures
176
thereof upwardly abutting against blocks
125
,
126
on opposite ends of the housing
11
and first feet
175
thereof pressing against an inner side of the shield
13
attached to an outer side of the housing
11
. Sometimes, customers want electrical connectors with grounding pads thereof retained in other ways.
Hence, an electrical connector with improved grounding bridges is desired.
SUMMARY OF THE INVENTION
An object of the present invention is to provide an electrical connector having grounding bridges which can be reliably retained therein and which can assure an electrical connection thereof with a shield of a mating connector complementary to the electrical connector.
To achieve the above object, an electrical connector in accordance with the present invention comprises an insulative housing having an elongated base wall and a mating wall projecting upwardly from the base, a plurality of terminals received in the housing, a metallic shield attached to an outer side of the insulative housing, and a pair of grounding bridges each having a body portion and a resilient arm extending upwardly from the body portion. A pair of guiding columns each defining a notch are provided on opposite ends of the mating wall of the housing. Each notch has an upper portion in the guiding column and a lower portion in the base wall and open to air from an upper surface of the base wall. The body portions of the grounding bridges are retained in the lower portions of the notches in the base wall and the resilient arms extend in the upper portions of the notches in the guiding column whereby the body portions of the grounding bridges electrically connect with the metallic shield from the upper surface of the base wall.
