BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an IC memory card connector, and more particularly to improvement of a connector used for an IC memory card which is a storage medium of an electronic notebook or a portable computer.

[0002]

2. Description of the Related Art A general structure of a conventional IC memory card is shown in FIGS. The frame 6 holding the printed circuit board 4 is sandwiched between two upper and lower reinforcing plates 5 covering the entire surface thereof, and a connector 10 having upper and lower two rows of soldering terminal portions is assembled to one end of the frame 6. Is
The printed circuit board 4 is sandwiched by the soldered terminal portions. A polar key 9 is provided on one side of one end of the frame 6.

[0003]

As described above, the conventional IC memory card having the solder terminal portions arranged in the upper and lower two rows is inferior in adaptability to the automatic mounting line. That is, to mount the connector 10 on the printed circuit board 4,
Usually, the upper surface of the connector 10 is sucked and placed at a predetermined position on the printed circuit board 4, and then the creamy solder previously applied on the substrate pattern of the printed circuit board 4 is re-fluidized to form a contact of the connector 10. Soldering connection is required. However, such a work cannot be automatically performed in the conventional connector of the type in which the printed circuit board 4 is sandwiched by the soldered terminal portions arranged in the upper and lower two rows.

Further, in the case of the conventional IC memory card, the polar key 9 is provided on the side surface of the frame 6 and the connector 1 is provided.
Since the entire structure including the zero portion is covered with the reinforcing plate 5 made of stainless steel or the like, the thickness of the entire memory card is increased by the thickness of the reinforcing plate 5, which hinders the thinning of the memory card.

An object of the present invention is to improve the compatibility with an automatic mounting line in the manufacture of an IC memory card and to achieve a thin memory card.

[0006]

An IC memory card connector according to the present invention comprises an insulator and a plurality of contacts press-fitted and fixed to the insulator, and a polar groove and a frame fixing protrusion are provided at both ends of the insulator. In addition to being formed, a plurality of contact holes are arranged side by side in two rows in the upper and lower direction, and the plurality of contacts are composed of a contact portion, a press-fitting portion, and a soldering terminal portion.
The soldered terminal portions of the contacts inserted in the contact holes of the row have the lower row located on the extension line of the contact portion, and the upper row at the spaced position decentered by a half pitch from the lower row. It is located on the same plane as and forms a staggered arrangement.

A long groove common to all the contact holes is formed in the insulator, and a locator divided into upper and lower two bodies is press-fitted into the long groove to hold the plurality of contacts.

[0008]

The zigzag arrangement of the soldered terminal portions of the contacts makes contact with only one surface of the printed circuit board for connection.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An example of the IC memory card connector of the present invention will be described below with reference to FIGS. In this memory card, as shown in FIG. 1, a frame 6 holding a printed circuit board 4 is sandwiched between two upper and lower reinforcing plates 5 each having a notch corresponding to a connector 10. On one end side of the frame 6, a connector 10 having a zigzag array of soldered terminal portions of the contacts 2 is assembled. The printed circuit board 4 is assembled so that the soldered terminal portion is in contact with one surface thereof.

As shown in FIG. 2, polar grooves 11 and frame fixing projections 12 for fixing the frame 6 are formed on both sides (only one is shown) of the insulator 1, and a plurality of them are provided between them. Contact holes 13 are arranged side by side. In the case of the present invention, the soldered terminal portions 23 of the contacts 2 are in a staggered arrangement as described above, but the contacts 2 themselves are arranged in two rows, upper and lower, as in the conventional case.
The contact holes 13 of the insulator 1 are also arranged vertically in two rows as shown in FIG. 2 (C).

As shown in FIGS. 3 to 5, the contact 2 comprises a contact portion 21, a press-fitting portion 22 and a soldering terminal portion 23. The contacts 2 themselves are inserted into the insulator 1 in a two-row arrangement in upper and lower rows via the locator 3 described later, and the soldered terminal portions 23 thereof are in a one-row zigzag arrangement. That is, the lower row of the soldered terminal portion 23 is located on the extension line of the contact portion 21. Further, the upper row is located on the same plane as the lower row at a separated position which is eccentric by a half pitch from the lower row. In this way, the soldered terminal portions 23 in the lower row and the upper row form a staggered arrangement.

The contact 2 having such a structure is inserted into the insulator 1 as shown in FIGS. 3 and 7 via the locator 3 shown in FIG. For this reason, as shown in FIG. 2, the long groove 14 common to the openings of all the contact holes 13 of the insulator 1 has the insulator 1.
Has been formed. The locator 3 is divided into upper and lower bodies, and is incorporated in the insulator 1 in the final step after press-fitting the soldered terminal portion. The locator 3 has a convex portion 31 and a concave portion 32 for alignment on both ends, and a groove portion 33 for correcting the deflection accuracy of the soldered terminal portion 23 in the middle. Further, the press-fitting portion 34 constitutes a convex portion for press-fitting and fixing in the long groove 14 of the insulator 1.

As is apparent from FIG. 7, the frame fixing convex portion 12 of the insulator 1 after assembly and the adhesive surface 35 of the locator 3 are substantially flush with each other and the edge portion of the cutout portion of the reinforcing plate 5. To provide the adhesive surface of the. If such a bonding surface 35 is not provided on the locator 3, the rigidity of the entire memory card cannot be maintained and the strength becomes weak.

[0014]

Since the soldering terminal portions 23 of the contacts 2 are arranged in a zigzag in one row, it is possible to mount the soldered terminal portions 23 at a predetermined position on the printed circuit board from its one surface side during automatic mounting. Therefore, the compatibility with the automatic mounting line is significantly improved.

By adopting the two-divided locator, it is possible to provide a thin memory card having rigidity. Furthermore, the easiness of bending the upper row of the soldered terminal portions due to the zigzag arrangement can be reinforced by using the locator.
