Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a socket connector, and more particularly to a lever eject type DIMM (DUAL).
INLINE MEMORY MODULE) socket connector.

[0002]

2. Description of the Related Art A conventional lever eject type DIM
The M socket connector has an insulator, a contact attached to the insulator, a lever rotatably attached to one end side of the insulator, a lever rotatably attached to the other end side of the insulator, and an insert into the insulator. And a DIMM substrate which comes into contact with the contacts, each lever is provided with a protrusion, and grooves are formed on both ends of the DIMM substrate to fit into the protrusion of each lever.

[0003]

The conventional lever eject type DIMM socket connector has a DIM
There is a drawback that the connector is not connected due to insufficient insertion of the M board into the lever, and conversely, the connector is damaged due to excessive insertion into the lever of the DIMM board.

Therefore, the present invention intends to prevent the connector from being disconnected due to insufficient insertion and the connector from being damaged due to excessive insertion by appropriately controlling the insertion depth of the board into the lever. .

[0005]

In order to solve the above problems, the present invention provides an insulator, a contact mounted on the insulator, a lever rotatably attached to one end side of the insulator, and an insulator other than the insulator. It is composed of a lever rotatably attached to the end side and a substrate which is inserted into the insulator and contacts the contact, each lever is provided with a protrusion, and at least one of the levers is provided with a protrusion. A socket connector is provided on both ends of which the protrusions of the respective levers are fitted, and a hole which is fitted on the protrusion of the lever is provided on at least one end of the substrate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 (b) shows a state in which the contact 2 is not yet assembled in the insulator 1. When the contact 2, the lever 3 and the lever 4 are press-fitted into the insulator 1 to be assembled, FIG. It becomes the state of.

FIG. 2 shows the contact 2 in FIG.
FIG. 3 is a cross-sectional view of a portion in which the
2 is inserted into a hole of a mounting board and fixed by soldering, and a DI, which will be described later, is provided between a pair of contact pieces 21 of the contact 2.
The MM board 5 is inserted.

A lever 3 shown in FIG. 3 (a) (left and right are drawn reversely) is inserted from the upper side 13 on one end side of the insulator 1, and a protrusion 3 provided on the lower outer surface thereof.
1 is fitted by being fitted into a hole 11 provided at one end side of the insulator 1. At this time, the protrusion 31 and the hole 1
There is a clearance between the lever 3 and the lever 1, and the lever 3 can rotate about the protrusion 31.

The lever 4 shown in FIG. 3B is inserted from the upper side 14 of the other end side of the insulator 1, and the projection 42 provided on the lower outer surface of the lever 4 is provided in the hole 12 provided on the other end side of the insulator 1. It is incorporated by being sandwiched between.
At this time, there is a clearance between the protrusion 42 and the hole 12, and the lever 4 can rotate about the protrusion 42 as an axis.

When the DIMM board 5 is inserted into the socket connector, the DIMM board 5 is guided by the groove 33 provided in the lower portion of the lever 3 and the groove 45 provided in the lower portion of the lever 4.

When mating the DIMM board 5 with the socket connector, first, the DIMM board 5 is inserted into the lever 4 and the upper portion 53 of the DIMM board 5 is pushed down.
The hole 51 provided at the lower right corner of the IMM board 5 is provided with the lever 4
Fit into the projection 41 provided on the inner surface of the lower part of the
The groove 52 provided near the upper right end of the IMM substrate 5 fits into the protrusion 44 provided on the upper portion of the lever 4. 4
Reference numeral 3 denotes a tip portion of the inner bottom surface of the lever 4. Next, DIMM
The groove 52 provided in the vicinity of the upper left end of the substrate 5 fits into the protrusion 32 provided in the center of the lever 3. From the above, D
The IMM board 5 is locked to the socket connector, and the conductor portion 54 provided under the DIMM board 5
Contacts the contact piece 21 of the contact 2.

When the operation portion 34 of the lever 3 is pushed outward in the longitudinal direction of the connector, that is, on the left side in FIG. 1A while the DIMM board 5 is engaged with the socket connector, the lever 3 is pushed.
Is rotated to the left by the lever principle, with the operating portion 34 as the force point, the protrusion 31 as the fulcrum, and the inner bottom surface tip portion 35 as the point of action. Then, the lower surface of the DIMM board 5 near the lower left end is pushed up, and is ejected upward from the socket connector.

The protrusion 41 of the lever 4 can be modified so as to be provided on the lever 3 by changing the design.
It can also be provided on both the lever 3 and the lever 4.

[0015]

As described above, according to the present invention, since the lever is provided with the protrusion that fits into the hole of the substrate, a clicking feeling can be obtained when the substrate is inserted into the lever. Since insufficient insertion of the lever into the lever is prevented, various problems due to insufficient insertion do not occur. Further, there is no problem of damaging the connector due to excessive insertion.
