ABSTRACT:
BACKGROUND OF THE INVENTION
The present invention relates generally to a connector structure and, more particularly, to a connector for connecting an electronic card, having a strengthened and integrated structure to provide a reliable contact and a stable connection with the electronic card.
FIGS. 1 and 2
show a conventional connector structure disclosed in the Taiwan Patent Application No. 91200027. The connector
10
a
is for connecting an electronic card
30
a
such as a memory card (e.g. a memory stick and a smart media and etc.) or a SIM card. The connector
10
a
is mounted on a printed circuit board (PCB) to electrically connect the electronic card
30
a
to the PCB.
The connector
10
a
includes an insulated body
11
a
, a plurality of terminals
12
a
, a seesawing mount
13
a
and two springs
14
a
. The terminals
12
a
are aligned in two rows, and each row includes multiple (e.g. four) terminals
12
a
. Each terminal
12
a
has a soldering portion
15
a
and a contact portion
16
a
. The soldering portion
15
a
is extended out and the contact portion
16
a
is penetrated into the insulated body
11
a.
There are two pivotal holes for receiving the corresponding shafts
17
a
of the seesawing mount
13
a
. The first end
18
a
of the seesawing mount
13
a
is normally lifted by the springs
14
a
to have the second end
19
a
press down the contact portions
16
a
of the terminals
12
a
, as shown in FIG.
1
. After the electronic card
30
a
is furnished, as shown in
FIG. 2
, the first end
18
a
of the seesawing mount
13
a
is pushed down and the second end
19
a
of the seesawing mount
13
a
is lifted to have the contact portions
16
a
of the terminals
12
a
to contact with the electronic card
30
a.
The above-mentioned connector
10
a
is mounted on the PCB by a surface mounting technology (SMT). After the surface of the PCB is coated with the solder and the connector
10
a
is place thereon, a heating process at a temperature about 180 to 230° C. is provided to adhere the soldering portions
15
a
of terminals
12
a
on the PCB.
However, the conventional connector has the drawbacks as follows.
Firstly, the springs
14
a
are located right beneath the first end
18
a
of the seesawing mount
13
a
, an exerting force of the electronic card
30
a
to push against the first end
18
a
of the seesawing mount
13
a
has to be larger than an elastic force of the springs
14
a
. The front end of the electronic card
30
a
may be easy to get attrition.
Secondly, as in
FIG. 1
, both the first end
18
a
and the second end
19
a
of the seesawing mount
13
a
are under the upward force of the springs
14
a
and the contact portions
16
a
of the terminals
12
a
, respectively. The seesawing mount
13
a
may be easy to get breakdown. Further, the seesawing mount
13
a
may be damaged due to the deformation and may not be used to provide the reliable seesaw effect after the heating process to mount the connector
10
a.
Therefore, there exist inconvenience and drawbacks for practically application of the above conventional connector structure. There is thus a substantial need to provide an improved electronic card connector that resolves the above drawbacks and can be used more conveniently and practically.
BRIEF SUMMARY OF THE INVENTION
The present invention provides an electronic card connector having an improved seesawing mount to provide a reliable contact and stable connection with the electronic card.
The electronic card connector provided by the present invention includes an insulated body, a plurality of terminals, a seesawing mount and a resilient element. The insulated body has an opening with a plurality of holes formed on at least one wall of the opening. Each terminal has a contact portion for penetrating through a respective hole on the wall into the opening. The seesawing mount is furnished in the opening with a first end and a second end. The second end of the seesawing mount is located above the contact portions of the terminals. The resilient element has one end mounted on the insulated body and the other end pressing down the second end of the seesawing mount to press down the contact portions of the terminals.
Therefore, the present invention installs a light emitting diode and a switch on a push handle of a car cigarette lighter, such that when the lighter is conducted, the user or driver can easily observe the conducting status by the light generated by the light emitting diode.
