れていない。[0004] A problem with such a small and high-density electrical connector is that since the contact interval is about 1 mm, the size of the mating connector is small.
It is extremely difficult to make an electrical connection by properly aligning all corresponding contacts of a pair of connectors, that is, aligning a pair of connectors. Similarly, a large number of contacts in each connector are connected to openings (through holes) in the circuit board to which this connector is attached.
Or, there is also a problem in correctly aligning the contact pads. The latter problem can be solved to some extent by providing positioning posts and / or elastic holding fittings in the insulating housing of each connector and inserting them into openings formed in predetermined positions on the circuit board. An example is JP-A-62-12009

However, it should be understood that the present invention should not be limited to only these examples. Since the multiple contacts of each electrical connector and the through-holes or contact pads on the corresponding circuit board are referenced to the locating hardware, the mounting screws are preferably used with such locating hardware, but should not necessarily be limited thereto. is not. Each contact does not necessarily have to be a tine-shaped terminal inserted into a through hole of a circuit board, and may be a so-called surface mount (SMT) type terminal. Further, the orientation may be determined by making a difference in the dimensional shape of the guide hole corresponding to the plurality of pin protrusions. In this case, the fitting portion of each electrical connector may be formed in a symmetrical shape instead of a D-shape. Further, a pair of connectors to be fitted by fitting a screw having a pin-like projection and a screw having a tapered hole to both ends of each connector may be provided in a fitting direction. Further, such a pin-shaped projection and a screw with a tapered hole may be formed on an arbitrary portion other than both ends of the connector.

A plurality of mounting screws having pin-shaped protrusions or tapered center holes are provided on the mating surface side of the mating connector near both ends of the electric connector, and positioned in the opening of the circuit board near both ends of the electric connector. Since the fixed positioning and holding bracket is attached and the mounting screw is screwed with the positioning and holding bracket, the mounting screw is engaged with the corresponding connector prior to the contact of the corresponding contact when the electric connector and the mating connector are fitted. It has both a function of a guiding means for guiding the fitting of the electric connector and the mating connector, and a function of a fixing means for fixing the electric connector to the panel and fixing the positioning and holding metal fittings to the electric connector. Also,
Since it is not necessary to separately provide a space for mounting screws and a space for mounting positioning and holding brackets in the electrical connector, the electrical connector can be downsized. Further, the ground connection between the electric connector, the circuit board and the panel can be achieved with a small number of parts.

及びパネル間の接地接続が可能になる。According to a second aspect of the present invention, a plurality of pin-equipped mounting screws having pin-like projections protruding from the mating surface are provided near both ends of one of the pair of connectors. And a positioning and holding metal fitting into which the mounting screw with the pin is screwed and positioned and fixed in the opening of the first circuit board, is provided near the both ends of the other connector of the pair of connectors from the fitting surface side. A plurality of mounting screws having a center hole having a center hole tapered rearward, and positioning and holding fittings screwed with the mounting screw having the center hole and positioned and fixed in an opening of the second circuit board are provided. When the pair of connectors are mated, the mounting screw with pin and the mounting screw with the center hole guide the mating of the pair of connectors. With bets a function of guiding means for guiding the fitting of the pair of connectors prior to contact, the functions of both the function of fixing means for fixing the connector positioning and holding fixture fixes the connector to the panel. Further, since it is not necessary to separately provide a space for mounting the mounting screw and a space for mounting the positioning and holding brackets in the connector, the size of the connector can be reduced. Also, with a small number of parts, a pair of connectors, a first and a second circuit board,
And a ground connection between the panels.
