DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector,
In particular, the present invention relates to a connector having a connection structure for multi-core contacts.

[0002]

2. Description of the Related Art A conventional example of this type of connector is disclosed in Japanese Patent Application Laid-Open No. 58-53172. An example described in this publication will be described in detail with reference to FIGS.

[0003] Referring to FIGS. 7 and 8, in a conventional connector connection structure, a socket block 2 is attached to a card 1, and a pin block 4 is attached to a backboard 3 side. Further, the card 1 is pushed into the unit, and the socket block 2 is fitted to the pin block 4.

In this state, when the pin 7 in the pin block 4 is pushed into the socket 6 in the socket 2,
The contact portion of the socket 6 is pushed up, and the two products are plugged in by sliding contact.

[0005]

When connecting with this conventional connector, the contact force between the pin and the socket is directly applied to the insertion / extraction force, so that the insertion / extraction force increases as the number of connection pins increases. Computers are becoming denser,
Along with this, multi-connection of electric signals and the like is increasing. Due to these increases, especially in a connection structure with a large number of pins, there is a problem that the additional insertion / extraction force to each pin or socket becomes uneven, and the pin or socket is damaged or deformed.

[0006] It is an object of the present invention to provide a connector capable of reducing the occurrence of poor connection.

Another object of the present invention is to provide a connector that does not cause damage or deformation to pins and sockets.

[0008]

According to a first connector of the present invention, there is provided a socket having a rod-shaped pin, a socket having a mouth portion with a larger interval due to the external dimensions of the pin, and the socket being inserted into the pin when the socket is inserted into the pin. And a guide for guiding the insertion direction of the mouth portion of the socket so as to clamp the pin.

A second connector according to the present invention comprises a rod-shaped pin, a lip portion having a feeling larger than the outer dimension of the pin, a holding portion having a coil spring, a bottom portion which comes into contact with a tip end surface of the pin and is pressed by the pin, And a socket having a tongue that is guided so that the lip clamps the pin by pressing the bottom, and a guide that guides the tongue when the socket is inserted into the pin.

A third connector according to the present invention has a large upper and lower cross-sectional shape, at least an outer surface of which is formed of an insulating material, and a middle portion between the upper and lower portions is narrowed and formed of an electric conductor. And a socket having a lip at an interval greater than the outer dimensions of the pin and having the lip clamped at the middle of the pin when inserted into the pin.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, according to a first embodiment of the present invention, a trapezoid which serves as a guide in the insertion direction around the tip of the socket 6 when inserting the rod-shaped pin 7 and the socket 6 which clamps the pin 7 is used. The pin block 4 having a guide 8 having a cross-sectional shape, and the tip of the pin 6 is wider than the diameter of the pin 7 so that the tip of the pin 7 is inclined when the pin 7 passes through a portion where stable contact can be made without load. And a socket block 2 having a socket 6 which is guided by a connector and has both ends contracted and a pin 7 held therebetween. The portion of the pin block 4 other than the pins 7 and the portion of the socket block 2 other than the socket 6 may be made of an insulating material, but plastic or reinforced plastic is particularly desirable. Because it is light and strong. The pin 7 and the socket 6 may be electrically conductive. The diameter of the pin is desirably about 0.5 mm-3 mm,
Preferably, the socket is gold plated.

Next, the operation of the first embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 1, when relaying or connecting an electric signal or a power supply system, the socket block 2 is pressed against the pin block 4 so that the pins 7 provided on the pin block 4 are pressed. Socket block 2
Input Riko <br/> No in the unloaded state to the inner surface of the socket 6 provided.

Referring to FIG. 2, when the insertion of the pin 7 into the socket 6 passes through a portion where stable contact is possible, the tip of the socket 6 is guided by the inclined surface of the guide 8 provided on the pin block 4, By shrinking the mouth 61 of the socket, the pin 7 and the socket 6 are securely connected. In the first and the embodiments of the present invention, the provision of the socket 6, the bar-shaped pin 7, and the guide 8 having the tip wider than the diameter of the pin 7 causes uneven load insertion / extraction force which is likely to be generated at the time of connection with another pin. It has the effect of preventing damage and deformation of pins and sockets.

Next, a second embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 3, according to a second embodiment of the present invention, a pin block 4 having only a rod-shaped pin 7 without a guide 8 and a tip 61 having a holding portion 62 wider than the outer shape of the pin 7 are shown. And a bottom 63 of the socket 6 is provided with a pin 7.
The tongue 64 of the socket 6 is guided so as to apply pressure from the outside when the spring 10 is contracted by the pressure, and the socket block 2 having the guide 8 is provided.

The pin blocks 4 except for the pins 7 and the socket block 2 except for the socket 6 and the spring 10 are preferably made of plastic or reinforced plastic. The spring 10 and the socket 6 may be made of metal, and the surface of the socket 6 is preferably plated with gold. The diameter of the pin 7 is from 0.5 mm to 2
About 3 mm is desirable. The pin 7 may be an electrical conductor.

Next, the operation of the second embodiment of the present invention will be described in detail with reference to FIGS.

Referring to FIG. 3, when relaying or connecting an electric signal or a power supply system, the socket block 2 is pressed against the pin block 4 so that the pins 7 provided on the pin block 4 are pressed. Socket block 2
It enters into the inside of the sliding socket 6 provided in the portion in a no-load state.

Referring to FIG. 4, when the tip of the pin 7 reaches the bottom 63 of the socket 6, the socket 6 moves to the back side by the pressing force of the pin 7. By the movement of the socket 6, the tip of the socket 6 is guided into the socket embedding hole of the socket block 2 having the inclined surface of the guide 8, the tip 61 of the socket 6 is contracted by the inclined surface, and the pin 7 and the socket 6 are securely connected. Is performed.

The second embodiment of the present invention is directed to a slidable socket 6 having a rod-shaped pin 7 and a tip 61 which is wider than the outer shape of the pin 7 and which has a spilling 10 which is a coil spring in a holding portion 62.
By providing the guide 8 around the socket 6, it is possible to prevent damage or deformation of the pin or socket due to uneven load insertion / extraction force, which tends to occur when connecting another pin.

Next, a third embodiment of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 5, a third embodiment of the present invention is such that the pins 7 are thicker at the upper and lower portions, and thin at a portion in the middle, so that the pins 7 are made of an insulator such as resin or plastic. A pin block 4 having a guide pin 9 coated on the surface thereof and a socket block 2 having a socket 6 whose mouth 61 is narrower than the outer shape of the pin 7 are provided.
