DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to an improvement in a technique for arranging socket contacts of a thin connector for a memory card.

[0002]

2. Description of the Related Art FIG.
And as shown in FIG. 6, the socket contacts 12 arranged orthogonally and parallel to the outer surface of the housing 11 are engaged with the comb teeth on the inner surface of the housing 11 to provide a gap between them. Thereby, insulation between the socket contacts 12 adjacent to each other is performed.

As shown in FIGS. 4 and 5, each socket contact 12 has a pair of contact portions 13 and a contact spring piece 14.
A pin contact 8 is inserted into the socket contact 12.

However, in the conventional structure as described above, there is a limit to miniaturization due to restrictions such as the thickness of the housing, the structural dimensions of the elastically deformable portion, and the pin diameter of the mating socket contact. Was. Therefore, in the conventional connector in which the socket contacts are arranged orthogonally to the outer surface of the housing, there is a problem that it is difficult to reduce the thickness of the structure. An object of the present invention is to solve the above-described problems in the conventional connector and to provide a connector capable of reducing the thickness of the connector.

[0005]

According to the present invention, a housing member having a serrated inner surface extending in a predetermined direction and a flat outer surface is disposed, and a plurality of socket contacts extending in a predetermined direction are provided. As inclined with respect to the outer surface of the housing member , and in parallel , and supported in contact with the saw-toothed inner surface, and configured to be provided with an insulating coating on the plurality of socket contacts,
A connector is obtained, wherein the mating pin contact is supported by the insulating contact between the socket contact and each of the adjacent socket contacts.

According to the present invention, a plurality of socket contacts extending in a predetermined direction are inclined with respect to an outer surface of a housing member having a serrated inner surface extending in a predetermined direction and a flat outer surface. And the socket contacts are mounted in an inclined state on the inner surface of the housing member, and an insulating film is provided on the plurality of socket contacts, and the socket contacts and the adjacent socket contacts are arranged in parallel. A connector characterized in that a mating pin contact is supported by an insulating film portion between socket contacts.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIGS. In FIG. 1, a housing 1 having a serrated inner surface and a flat outer surface is arranged, a plurality of socket contacts 2 extending in a predetermined direction are inclined with respect to the outer surface of the housing 1, and the saw tooth is provided. The socket contacts 2 are press-fitted and supported on the inner surface of each of the sockets, and the socket contacts 2 are brought into parallel contact with each other so that the pitch between the center portions of the plurality of socket contacts 2 is equal to each other. 7 are arranged in close contact with each other.

In FIG. 2, a pair of contact spring pieces 4 extending in a predetermined direction and a contact portion 3 provided at the tip of the contact spring piece 4 are provided.
And the holding portion 5 of each socket contact 2 formed by the contact portion consisting of: They are installed side by side.

FIG. 3 is a cross-sectional view of the connector near the contact point of the socket contact 2 in the fitted state, and shows a contact state between the socket contact 2 and the pin contact 8. As can be seen from FIG. 3, it can be seen that the socket contact 2 is made thinner by inclining it with respect to the outer surface of the housing 1 than the thickness of the connector having the conventional structure. In addition, the pin contact 8 is supported by a plurality of socket contacts 2 (four socket contacts 2 in FIG. 3) around the pin contact 8, so that the pin contact 8 does not shift.

[0010]

According to the present invention, since the socket contacts are inclined, the overall thickness can be reduced. Moreover, there is no gap between the socket contacts as in the past,
Since the adjacent socket contacts are in close contact with each other via the insulating film, the pitch can be narrowed, which also greatly contributes to downsizing of the connector.
