DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a card edge connector, and more particularly to a card edge connector for rotating a memory card, an IC card, or the like (hereinafter, simply referred to as a card) for horizontal connection with a mounting board.

[0002]

2. Description of the Related Art A card edge connector is usually mounted on a mounting board such as a printed board, and is used to read or write a data file of a computer by inserting a card. BACKGROUND OF THE INVENTION
In recent years, the mounting density has become higher and the mounting area has become insufficient, and the height of the device has been reduced. In order to minimize the mounting area, a card edge connector is used which inserts a card obliquely from above and rotates the card to its operating position to make electrical contact. The connection between the contact of the card edge connector and the mounting board is usually surface-mounted in order to increase the density.

Conventionally, various types of edge connectors have been developed to meet such a demand for high-density mounting. For example, there is a card edge connector disclosed in Japanese Utility Model Laid-Open No. 6-31088. . In this conventional card edge connector, a receiving groove and a guide groove for receiving a memory card are formed inside a substantially U-shaped insulating housing. An uneven engaging portion including a protruding wall is formed on an upper side wall of the guide groove. The memory card is
The two concave and convex engaging portions are aligned and guided to the guide groove, and then pressed toward the body having the contact to be connected. The connection arms of adjacent contacts alternately contact the conductive pads on the top and bottom surfaces of the memory card to prevent stress concentration on the housing holding the contacts.

There was a problem that was.

Further, since the soldered portion of the lead as a surface mount has a structure in which the lead and the fixed portion are continuous, the load in the lateral direction increases due to the dimensional change of the long connector due to the difference in thermal expansion at high temperature. There were also problems.

It is an object of the present invention to provide a card edge connector which can solve the above-mentioned problems of the prior art.

FIG. 6 is an enlarged cross-sectional view of the base 111 of the card edge connector 100 according to the above-described embodiment in a state where the card edge connector 100 is surface-mounted on the printed circuit board 1. FIG. 7 is a view similar to FIG. 6, but showing that the card 200 has been mated and the card 200 is in the latched state.

As shown in FIGS. 6 and 7, when the card edge connector 100 is surface-mounted on the printed circuit board 1, the card edge connector 100 is inserted into an alignment hole 1A formed at a predetermined position on the printed circuit board 1. Card edge connector 1
The card edge connector 100 is placed on the printed circuit board 1 such that the corresponding positioning posts 117 formed on the lower surface of the base 111 of the insulating housing 110 are fitted.

Are mounted on respective corresponding circuit conductors (not shown) formed on the upper surface of the printed circuit board 1, and soldering may be performed in this state.

In order to fit the card 200 to the card edge connector 100 surface-mounted on the printed circuit board 1 as described above, first, as shown in FIG. , The long groove 11 of the base 111
2 is inserted into the long groove 112 from an oblique direction with respect to the extension direction. At this time, the separation distance between the contact portion 13A of the first type contact 10 and the contact portion 23A of the second type contact 20 in the direction orthogonal to the insertion direction of the card 200 is Since the thickness is slightly larger than the thickness of the lower end, the insertion force required for that is substantially zero.

0 is rotated toward the printed circuit board 1 so that the card 2
If the both side edges of 00 are moved over the locking portion 116 (see FIG. 1), the card 200 is latched by the locking portion 116 in the fitted state as shown in FIG. In such a latched state, the first
13A of the second type of contact 10 and the contact portion 23A of the second type of contact 20, each corresponding contact (not shown) arranged on the upper surface of the lower end of the card 200 and the lower end of the card 200 Each corresponding contact (not shown) arranged on the lower surface of the unit is kept in contact with each other.

From the oblique insertion position as shown in FIG.
When the card 200 is rotated to the mating latch position shown in FIG.
3A is slightly shifted upward against the elastic shifting force of the arm portion 13 by being contacted by the contacts arranged on the upper surface of the lower end portion of the card 200, while the second type is The contact portion 23A of the arm portion 23 of the contact 20
By being brought into contact with the contacts arranged on the lower surface of the lower end of the card 200, the card 200 is slightly displaced downward against the elastic displacement force of the arm 23. In the mating latch state shown in FIG.
The contact pressure between the contact portion 23A and the contact on the lower surface of the card 200 is given by the elastic shift force of each arm 13 and the contact pressure between the contact portion 23A and the contact on the lower surface of the card 200 is given by the elastic shift force of each arm 23. Have been. In order to remove the card from the fitted latch state shown in FIG. 7, it is only necessary to shift the movable arm 115 outward so as to remove the locking portion 116 from the side edge of the card 200. The arm 200 is rotated to a position as shown in FIG.
You just have to pull it out.

The force exerted by the arms 13 and 23 applied to the card 200 when the card 200 is fitted or removed is limited to the arm 13 in the first type of contact 10.
Has a large curved L-shape, and the second type of contact 20
Since the arm portion 23 has an S-shape, the overall length of the arm is increased, so that it is soft. In other words, since the arm has a long overall length, the stiffness of the spring is reduced and the thickness of the card can be increased. In addition, sufficient spring characteristics can be exhibited in a small space.

In addition, in the first type of contact 10, the first mounting leg 14 and the second mounting leg 12
Since the contact is fixed to the insulating housing at the two positions, the stress can be dispersed and the deformation of the insulating housing can be prevented.

Furthermore, since the fulcrum of the arm portions 13 and 23 is far from the connection portions 15 and 25 and closer to the mounting leg, the contact pressure between the contact portion of the arm portion and the contact of the card is applied to the connection portion. The effect is small. In addition, in the first type of contact 10, a groove 15 </ b> A is formed between the connecting portion 15 and the second mounting leg 12, and
In the contact 20 of the type shown in FIG.
Since a groove 25A is formed between the connecting portions 1, the connecting portions 15 and 25 can be flexibly deformed. Therefore, since the surface mounting portion and the card fitting move semi-independently, the load in the lateral direction can be reduced by the dimensional change of the long connector due to the difference in thermal expansion at high temperature, and the influence on the soldering portion can be reduced. That is, an effect is obtained in that the horizontal and vertical stresses applied to the connection portion can be absorbed.

Since the overall length of the arm portion of the contact is increased, the stiffness of the spring is reduced and the thickness of the card can be increased.

Since the entire length of the arm portion of the contact is long, sufficient spring characteristics can be exhibited in a small space.

Since the contacts are fixed at two positions, stress can be dispersed and deformation of the housing can be prevented.

Since the fulcrum of the arm portion is away from the connection portion and close to the mounting leg portion, it is possible to reduce the influence of the load on the connection portion when the card is fitted.

Since the groove is formed in a part of the contact at the base of the connection part, the stress applied to the connection part from the lateral direction can be absorbed, and the influence on the soldering part can be reduced.
