ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention is related to a card connector assembly, and particularly to a card connector assembly mounted on a mother board through a daughter board.
2. Description of the Related Art
Referring to
FIG. 4
of the present application, a conventional card connector assembly
1
′ comprises a card connector
6
′, a daughter board
7
′, and a socket connector
8
′, wherein the card connector
6
′ has two side arms
62
′ and a header connector
63
′ connecting the side arms
62
′. The header connector
63
′ has an engaging face
631
′ and a mounting face
632
′. A plurality of terminals
61
′ are received in a plurality of passageways of the header connector
63
′, respectively. One end of each terminal
61
′ extends out of the engaging face
631
′ and the other end extends out of the mounting face
632
′ through a conductive hole
71
′ of the daughter board
7
′ to be soldered thereto. A lower portion of the daughter board
7
′ defines a plurality of golden fingers
72
′. When the daughter board
7
′ is inserted into the socket connector
8
′, the golden fingers
72
′ connect with mating terminals
81
′ of the socket connector
8
′. The mating terminals
81
′ are soldered to the mother board
9
′. Thus, the card connector
6
′ and the mother board
9
′ are electrically connected together.
There is no positioning means in the conventional card connector assembly whereby the daughter board cannot obtain a good positional accuracy when it is mounted to the card connector. Furthermore, in the prior art there is no positioning means between the daughter board and the socket connector, which causes the daughter board to be easily improperly inserted into the socket. Such an improper insertion may cause a damage of a housing of the socket connector since it is soft than the daughter board. Furthermore, the improper insertion may result in that the daughter cannot have a correct electrical connection with the socket connector. Accordingly, an improved card connector assembly is needed.
BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide a card connector assembly which can have a correct connection with a socket connector.
Another object of the present invention is to provide a card connector assembly wherein a daughter board can be precisely mounted to a header connector of the card connector assembly.
To achieve the above-mentioned objects, a card connector assembly comprises a card connector, a spacer defining a plurality of through holes, a daughter board defining a plurality of conductive holes and a rear socket mounted on a mother board. The card connector consists of a header connector with a plurality of terminals received in passageways defined in an insulating housing of the header connector and two arms extending from two lateral sides of the header connector. Each of the terminals extends out of a mounting face of the header connector through a through hole in the spacer. By the help of the spacer which correctly positions the terminals, the terminals are easily and accurately inserted into the conductive holes of the daughter board. Each side arm defines a step portion and a protrusion portion with a guiding face. A hook with a inclined face in accordance with the guiding face extends from the spacer and can latch with the protrusion portion. A pair of studs extending from the spacer in the opposite direction from the hook and fit into a pair of recesses defined in the daughter board. A plurality of golden fingers on a bottom of the daughter board connect electrically with a plurality of mating terminals in the socket connector when the daughter board is inserted into the socket connector.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description of the preferred embodiment when taken in conjunction with the accompanying drawings.
