ABSTRACT:

BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
The present invention is related to an electronic card connector having lower height and wider bottom face. The electronic card connector can be more stably rested. In addition, the structure of the conductive terminals of the connector are simplified.
FIG. 6
shows a conventional electronic card connector. A second connector
12
is overlaid on a first connector
11
. The first conductive pins
16
of the front end of the first connector
11
are windingly bent and inserted into the insertion holes
14
of a socket
13
. The conductive pins
16
electrically contact with the conductive terminals
15
disposed in the insertion holes
14
. The above structure has a shortcoming, that is, the first conductive pins
16
are windingly bent so that the processing procedure is complicated and time-consuming. In addition, the ratio of good product is quite low.
FIG. 7
shows a second type of conventional electronic card connector. A second connector
22
is overlaid on a first connector
21
. The forward extending first and second conductive pins
23
,
24
of the first and second connectors
21
,
22
are both first soldered on a circuit board
25
and then the circuit board
25
is inserted in an insertion slot
28
of a socket
27
soldered on a circuit board
26
. The conductive pins
23
,
24
electrically contact with the conductive terminals
29
disposed in the insertion slot
28
. The above structure has a shortcoming, that is, the socket
27
must be first soldered on the circuit board
26
and then the circuit board
25
is inserted into the socket
27
. The processing time is long and the processing cost is high.
FIG. 8
shows a third type of conventional electronic card connector. A second connector
32
is overlaid on a first connector
31
. The socket
33
has four steps of insertion slots
34
. A conductive terminal is inserted in each insertion slot
34
. The forward extending first and second conductive pins
37
,
38
of the first and second connectors
31
,
32
are respectively inserted in the insertion slots
34
to contact with the conductive terminals
35
. The above structure has a shortcoming, that is, the socket
33
must be formed with four steps of insertion slots
34
at different heights. Therefore, the socket
33
will have a considerable height. When the socket
33
disposed on the circuit board
36
passes through the soldering furnace along with the circuit board
36
, the socket
33
is too high and tends to fall down. This makes it impossible to solder the socket
33
on the circuit board
36
.
SUMMARY OF THE INVENTION
It is therefore a primary object of the present invention to provide an electronic card connector in which the bottom face of the pin socket is wider and the height of the pin socket is lowered. Therefore, the pin socket can stably pass through the soldering furnace without falling down.
It is a further object of the present invention to provide the above electronic card connector in which the structure of the conductive terminal is simplified. Therefore, the electronic card connector is easier to manufacture and process.
According to the above objects, the electronic card connector of the present invention includes a pin socket, a first connector and a second connector. The pin socket is disposed on a circuit board. The pin socket includes an insulating seat, a first conductive terminal and a second conductive terminal.
The insulating seat has: a first face soldered on a circuit board; a second face opposite to the first face: a third face formed on one side of the first face and second face; multiple insertion holes extending from the second face to the first face and passing through the first face and second face; a first step section formed on the other side of the first face of the pin socket; multiple first insertion slots passing through the first step section and the first face; a second step section formed on an edge of the first step section, the second step section being lower than the first step section; multiple second insertion slots passing through the second step section and the first face; a first end formed at one end of the first face, second face, third face, first step section and second step section; and a second end formed at the other end of the first face, second face, third face, first step section and second step section.
One end of the first conductive terminal is inserted in each first insertion slot of the first step section and each second insertion slot of the second step section of the pin socket. The other end of the first conductive terminal is soldered on the circuit board.
One end of the second conductive terminal is inserted in each insertion hole of the pin socket. The other end of the second conductive terminal is soldered on the circuit board.
The first connector has: a first side; a second side opposite to the first side; a third side, two ends of the third side being connected with two corresponding ends of the first side and second side; and a fourth side, two ends of the fourth side being connected with two other corresponding ends of the first side and second side, the third side and fourth side being respectively formed with insertion channels, the two insertion channels respectively having openings on the second side, whereby an electronic card can be inserted into the two openings, a group of first conductive pins being inlaid in the first side, the first conductive pins extending from the first side in a first direction distal from the second side, the first conductive pins respectively riding in the first insertion slots of the first step section and the second insertion slots of the second step section and being bridged with the first conductive terminals.
The second connector is overlaid on the first connector. The second connector has: a first side; a second side opposite to the first side; a third side, two ends of the third side being connected with two corresponding ends of the first side and second side; and a fourth side, two ends of the fourth side being connected with two other corresponding ends of the first side and second side, the third side and fourth side being respectively formed with insertion channels, the insertion channels respectively having openings on the second side, whereby an electronic card can be inserted into the two openings, a group of second conductive pins being inlaid in the first side, the first conductive pins extending from the first side in a first direction distal from the second side and then 90 degrees tuning and extending in a second direction, the second conductive pins being respectively inserted in the insertion holes of the second face of the pin socket and contacting with the second conductive terminals.
The electronic card connector further includes a protective member attaching to the second face of the pin socket. The protective member has multiple through holes respectively corresponding to the insertion holes. The group of second conductive pins of the second connector are passed through the through holes for protecting the second conductive pins.
