BACKGROUND OF THE INVENTION The present invention relates to an electrical connector, and
The present invention relates to an inter-board electrical connector for electrically interconnecting corresponding circuits on a single board.

[0002]

BACKGROUND OF THE INVENTION Board-to-board electrical connectors are used to interconnect circuits on a daughter board to a motherboard or backplane. These substrates are mounted in a vertical or horizontal relationship according to the shape of the connector member to be fitted.

[0003] The demand for connectors that solve problems such as common mode noise and crosstalk has increased with increasing density and speed of electronic circuits. Accordingly, it is desirable to have a high density electrical connector having means for providing low inductance and low resistance ground connections from the connector to the board to which it is attached.

US Pat. No. 4,867,690 discloses an electrical connector system having a pin header having a plurality of rows of terminal members extending parallel to a side wall. The outermost terminal row adjacent to the side wall is arranged to provide a ground reference path, and the other terminal rows are arranged to fit into the receptacle member.

US Pat. No. 4,655,518 discloses a two-part connector having a ground contact along the dielectric sidewall of the corresponding connector. The terminal member of the pin header is positioned in a recess along the inner surface of the side wall and has a convex single elastic beam contact facing inward toward the pin terminal positioned between the side walls. Since the ground contact is arranged along the outer surface of the side wall in the receptacle member, the ground contact is slidably connected to the elastic beam in the pin header when the connector is fitted.

Providing a means for a particular application to provide a switching effect in which any two adjacent contacts are shorted together when the mating connector and board are removed from the system to maintain electrical continuity of the system. Is preferred.
This "recessed" switch does not require extra components to achieve the same performance.

High-density, high-speed electronic systems are prone to electromagnetic interference (EMI) or radio interference (RFI) and it is generally preferable to provide means for shielding the module in the system to protect against them. Accordingly, connector assemblies used in the system include means to facilitate interconnection of the module shield to the ground plane within the motherboard or backplane. For this purpose,
Buried pin header "," Shielded receptacle "
Or the term "shielded connector assembly"
It should be understood to mean a ground plate or other component having the above-mentioned performance. Furthermore, mating members of a grounded or shielded connector assembly that are cost / effective in order to enhance the quality of current electronic systems such as computers and industrial equipment, have corresponding current complementary grounded or screened complementary components. It is preferable that it can be fitted with a member that is not present.

It is an object of the present invention to protect the ground contact terminals of the receptacle member, provide a reliable ground connection, and provide additional low inductance and low resistance conductive paths to reduce the electrical performance of the connector. It is to improve.

It is also an object of the present invention to provide an electrical continuity when the board is removed from the system by providing a short circuit or switching means at adjacent contact terminals to use extra components to perform the same function. Is not necessary.

Another object of the present invention is to provide a means for facilitating interconnection of system shields.

It is a further object of the present invention to provide a shielded connector system that is compatible with conventional unshielded connectors.

While some objects and effects of the present invention have been described above, other objects and effects will be disclosed as the description proceeds with reference to the accompanying drawings.
