[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector for electrically connecting a parent board and a child board, and more particularly to an electrical connector for connecting a memory module such as DIMM to an internal expansion memory board.

[0002]

2. Description of the Related Art In general, a computer system such as a personal computer is connected to an expansion board (child board) such as an expansion memory board or an interface board for peripheral devices, so that a socket called an electrical connector is provided on a motherboard (parent board). Equipped. By inserting the expansion board into the electric connector, the mother board and the expansion board can be electrically connected.

Here, the structure of a general electric connector is
An electrical connector for connecting an expansion memory module (hereinafter referred to as module) called a DIMM (Dual Inline Memory Module) will be described as an example.

FIG. 27 is a conceptual perspective view showing the configuration of a conventional electrical connector for DIMM, and shows an example of the configuration in a desktop personal computer, for example. In FIG. 27, a plurality of rows of housings 2 (here, 4
They are arranged in rows, and the user can add memory by inserting the module 3 into a predetermined housing 2. When the housing 2 is placed upright on the motherboard 1 as shown in FIG. 27, the module 3 is held substantially at right angles to the motherboard 1.

[0005]

Generally, a desktop personal computer has a large body space, so that the number of housings is large and the expansion board is held perpendicular to the mother board. However, in a thin notebook computer or the like, the housing 2 cannot be set upright inside the main body as shown in FIG. 27. Therefore, as shown in FIG. 28, the housing 4 is arranged so as to be substantially parallel to the motherboard 5. There is. However, even in this case, a space for inserting the module 6 from the horizontal direction cannot be secured, so that the module 6 is obliquely inserted into the housing 4 and the tip of the module 6 is brought into contact with the housing 4 so that the module 6 is inserted into the motherboard 5. I try to put it on the side. A latch part (not shown) is provided at the tip of the arm 7 of the socket 4. When the module 6 is mounted in the socket 4, both ends of the module 6 are engaged and fixed by the latch part.

By the way, in a thin system such as a notebook type personal computer, only one expansion board can be mounted, but there is a demand to connect two expansion boards in order to expand the function of the system. When connecting two expansion boards, how to arrange the two housings becomes a problem. For example, when the two housings are arranged side by side, the surface area of the connector increases, so that there is a problem that the space in the main body cannot be effectively used. Further, in the case where the housings are arranged in upper and lower two stages, when the module 6 is inserted into the lower housing 4b as shown in FIG. 29, the module 6 and the upper housing 4b are inserted.
There is a problem in that the tip (latch portion) of the arm 7 of 7 may collide with the arm 7 so that it cannot be inserted properly.

An object of the present invention is to provide an electrical connector in which the housings are arranged in upper and lower stages so that the module can be easily inserted into the lower housing.

[0008]

In order to solve the above problems, an electrical connector of the present invention is an electrical connector for electrically connecting a parent board and a child board, and at least two housings for inserting the child boards are provided. In addition to arranging in stages, the upper housing can be retracted to a position where it does not interfere with the path when inserting the daughter board into the lower housing,
The upper housing is mounted so as to be movable in the horizontal direction.

[0009]

[0010]

According to the above-described electrical connector, when inserting the child board into the lower housing, the child board to be inserted and the upper housing do not interfere with each other, so that the lower child board can be easily installed. Can be inserted into.

Therefore, even in the structure in which the housings are arranged in two stages, the child boards can be easily inserted into each housing, so that two child boards are connected without increasing the thickness of the main body. It becomes possible.

[0012]
