ABSTRACT:

FIELD OF THE INVENTION
The present invention relates to an electrical connector capable of being mounted on a printed circuit board (“PCB”) or other substrate, and in particular, to an electrical connector capable of being mounted in a recess on an edge of a PCB in such a manner that a portion of the connector is located above an outer surface of the PCB and another portion of the connector is located below an outer surface of the PCB.
BACKGROUND OF THE INVENTION
Referring to FIG.
1
and
FIG. 2
, from which a conventional electrical connector adopted for a high speed transferring and relating to the IEEE 1394b standard mounted on an outer surface of a PCB
100
, and capable of being mated with a mating connector. The electrical connector includes an insulating housing
60
, a plurality of electrical terminals
70
disposed in the insulating housing
60
, an inner shield housing
80
covering the insulating housing
60
, and an outer shield housing
90
wrapping the insulating housing
60
.
The insulating housing
60
includes a base
61
and a pair mating plates arranged parallel and extending forwardly from the base
61
, the pair mating plates respectively define a first mating plate
62
and a second mating plate
63
, and the pair mating plates each has a plurality of slots
64
extending backwardly and penetrating through the base
61
. The electrical terminals
70
respectively and correspondingly receive in the slots
64
, and each has a contact portion
71
electrically engaging with the mating connector and a tail portion
72
exposing out of the insulating housing
60
and electrically connecting the PCB
100
.
The inner shield housing
80
covers a peripheral of each of the pair of mating plates and has a first cavity
81
formed therein. The outer shield housing
90
wraps a peripheral of the base
61
and extends forwardly, and the outer shield housing
90
has a second cavity
91
formed between the inner shield housing
80
and the outer shield housing
90
. The first cavity
81
and the second cavity
91
are applied with partial insertion of the mating connector for the mating connector electrically connecting the PCB
100
.
For the reason that the electrical connector firmly connects the mating connector, there are resilient members
82
,
92
respectively arranged on the inner shield housing
80
and the outer shield housing
90
for the resilient members
82
,
92
clamping the mating connector. However, the resilient members
92
are disposed on two sidewalls of the outer shield housing
90
and occupy space where wing tabs are needed when it is desired to mount the connector such that the connector is mounted within a recess at the edge of the PCB.
OBJECT AND SUMMARY OF THE INVENTION
One object of the present invention is to overcome the problems of the prior art noted above.
In particular, the object of the invention is therefore to specify an electrical connector has an outer shielding designed in a two-piece type and having a first shield member and a second shield member. The first shield member has a first resilient tab forwardly extending therefrom and the second shield member has a wing tab disposed therein, such that the first resilient tab and the wing tab will not interfere with each other, and so that the connector can be mounted in a recess on an edge of a PCB in such a manner that a portion of the connector is located above an outer surface of the PCB and another portion of the connector is located below the outer surface of the PCB. This results in a reduce height that the connector extends above the outer surface of the PCB.
According to the invention, this object is achieved by a electrical connector which includes an insulating housing having a plurality of slots, a plurality of electrical terminals respectively receiving in the slots, an inner shield housing including a first cavity formed therein and covering the insulating housing, and an outer shield housing covering the insulating housing. Each of the electrical terminals includes a contact portion electrically engaging with the mating connector and a tail portion exposing out of the insulating housing and electrically connecting the PCB. The outer shield housing has a first shield member and a second shield member combining with the first shield member integrally, which both respectively cover the insulating housing. A second cavity is formed between the first shield member and the second shield member. The first shield member has a first resilient tab forwardly extending from and connecting with each of two sidewalls thereof, the second shield member has a recess formed on each of two sidewalls thereof and relating to the first resilient tab for containing the first resilient tab into the recess, and a wing tab folded from a rim around the recess, thereby allowing the connector to be mounted within a recess at an edge of the PCB. Additionally, the wing tab may be firmly connecting to the PCB.
