2. Description of the Related Art A ZIF connection structure in which a pair of objects to be connected are fitted to each other and then relatively moved in a direction perpendicular to the fitting direction to connect these contacts to each other is disclosed in No. 61-6284 or 1-11
There is one disclosed in Japanese Patent No. 8448.

In the ZIF connection structures disclosed in these documents, the lever required for connection is applied as small as possible by applying the principle of leverage, and the intended purpose has been achieved.

In these connection structures, a pin-shaped contact having elasticity is arranged between objects to be connected, and the object to be connected is relatively moved in a direction perpendicular to the axial direction of the contact. The contact is pressed against a pin contact provided on an object to be connected. Therefore, when connecting between a pair of objects to be connected, the longer the length of the contact disposed between them,
The force required to press the contact against the pin contact of the object to be connected is small. For this reason, in the conventional ZIF connection structure, the length of the contact connecting between the pair of connection objects is set to be long.

[0005]

SUMMARY OF THE INVENTION As described above, the conventional Z
In the IF connection structure, it is necessary to increase the length of a contact connecting between a pair of connection objects for that purpose. However, the conduction distance becomes longer, and the connection distance between connection objects requiring transmission speed is increased. Was unsuitable for connection.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a ZIF connection structure capable of shortening the conduction distance and effectively responding to a high-speed signal.

[0007]

According to the present invention, a through hole formed in a first object to be connected and formed by a conductive inner wall surface, and a second hole is formed so as to face the through hole. A hole formed in the object to be connected, and constituted by a conductive inner wall surface,
When the first connection object and the second connection object face each other such that the through hole faces the hole, one end is inserted through the through hole and the elastic member is inserted into the hole. A ZIF connection structure comprising a conductor and a drive mechanism for moving the other end of the elastic conductor in a direction orthogonal to the axial direction of the through hole is obtained.

[0008]

According to the present invention, the first connection object is connected to the second connection object such that the through hole formed in the first connection object and the hole formed in the second connection object face each other. One end of the elastic conductor is inserted through the through-hole and inserted into the hole in this state. Thereafter, the other end of the elastic conductor is moved by the drive mechanism in a direction orthogonal to the axial direction of the through hole. Thereby, one end of the elastic conductor is pressed against the inner wall surface forming the through hole and the hole. As described above, the present invention is configured such that the other end of the elastic conductor is moved in a direction orthogonal to the axis of the through hole, and one end of the elastic conductor is pressed against the through hole and the inner wall surface forming the hole. Since only a small force is applied to the other end of the elastic conductor in a direction orthogonal to the axis of the through hole, one end of the elastic conductor is formed on the inner wall surface forming the through hole and the hole according to the leverage principle. Contact strongly.

As described above, if one end of the elastic conductor is pressed against the through-hole and the inner wall surface of the hole, these inner wall surfaces have conductivity, and thus the first connection object and the second connection object are , Are electrically connected to each other via one end of the elastic conductor.

[0010] Further, since the first connection object and the second connection object are electrically connected at one end of the elastic conductor, the conduction distance is short.

[0011]

Next, an embodiment of the present invention will be described.

FIG. 1 shows a first embodiment which is a basic principle of the present invention, and a first connection object (printed circuit board) 1 is shown.
Is made of an insulating material, a through hole 1a is formed at a predetermined position, and an inner wall surface forming the through hole 1a is subjected to a conductive treatment. Similarly, the second connection object (printed circuit board) 3 is also made of an insulating material, and is formed so that the hole 3 a faces the through hole 1 a of the first connection object 1. The through hole 1a of the first connection object 1 and the hole 3a of the second connection member 3 are set to have the same diameter, and are formed so that their axes coincide.

The elastic conductor 5 has a substantially pin shape. One end (tip) 5a of the elastic conductor 5 is formed with a through hole 1a and a hole 3a.
When the first connection object 1 and the second connection object 3 are brought into close contact and face each other such that they face each other, the through-hole 1a is inserted into the hole 3a.

The other end (drive end) 5b of the elastic conductor 5
Is moved by a driving mechanism (not shown) with a force of W in a direction (rightward in the figure) orthogonal to the axial direction of the through hole 1a. Then, at the lower end of the through-hole 1a of the first connection object 1, the portion near the distal end portion 5a of the elastic conductor 5 and the inner wall surface forming the through-hole 1a are pressed against each other by the force of P, and the elastic conductor 5 The tip has an inner wall surface defining the hole 3a and F

The distance from the other end 5b of the elastic conductor 5 to the contact portion 5c with the through hole 1a of the elastic conductor 5 is m.
Assuming that the distance from the contact portion 5c to the contact portion 5d with the hole 1a of the elastic conductor 5 is n, the above-mentioned forces F, P,
W becomes F = (m / n) W, P = ((m + n) / n) W, and the larger the value of m with respect to n, the greater the contact force P, F with a smaller driving force W. Will be done.

When the other end 5b of the elastic conductor 5 is moved as shown in FIG. 1, the second connection object 3 tends to move leftward in the drawing. If this movement is not prevented, the elastic conductor 5
Does not press against the inner wall surfaces of the through hole 1a and the hole 3a. Therefore, in order to prevent the movement of the second connection object 3, a stopper surface 1b is provided on the left end of the first connection object 1.

FIG. 2 shows a second embodiment, in which a connecting body 8 is arranged below the first connection object 1. The connecting body 8 forms a part of a driving mechanism for moving the other end 5b of the elastic conductor 5 to the through hole 1a in a direction orthogonal to the axial direction. The other end 5 of the elastic conductor 5 is
b is connected in a fixed state. In this case, when the other end 5b of the elastic conductor 5 is moved by the connecting body 8,
As shown in FIG. 2, the elastic conductor 5 bends in an S-shape. Thus, the elastic conductor 5 that bends in an S-shape is different from the one that bends the elastic conductor 5 in a bow shape as shown in FIG.
Although a large magnification of the driving force cannot be obtained, the driving force W '
Can be small.

FIG. 3 shows a third embodiment. In this embodiment, a spherical projection is formed on a portion of the elastic conductor 5 located in the through hole 1a of the first object 1 to be connected. 51 is formed, and this is brought into contact with the inner wall surface constituting the through hole 1a. In this case, an effect of eliminating the fluctuation of the tip of the elastic conductor 5 is also provided.

FIG. 4 shows a main part of the fourth embodiment.
In this embodiment, the socket contact 30 is implanted in the second connection target 3, and the socket contact 30
Is formed with a hole 3a. Other parts are the first
This is the same as the embodiment.

FIGS. 5 to 7 show a more specific embodiment (fifth embodiment) of the present invention, in which a guide pin 13 is formed on a first connection object 1 and a second connection object is formed. Connection object 3
Has a guide hole 33 formed therein. When the second connection object 3 is placed on the first connection object 1, the guide pin 13 is inserted through the guide hole 33 so that the second connection object 3 becomes the first connection object. 1 so that the axis of the through hole 1a coincides with the axis of the hole 3a.

A substantially rectangular cylindrical housing 7 made of an insulating material is mounted on the lower surface side of the first connection object 1, and a substantially rectangular cylindrical connecting body 8 made of an insulating material is provided inside the housing. Are movably arranged in a direction orthogonal to the axial direction of the through hole 1a. The connecting body 8 connects the other end portions of the plurality of elastic conductors 5 to each other. The connection between the connecting body 8 and the elastic conductor 5 is a spherical connection, and therefore, the elastic conductor 5 is configured to be rotatable around the other end. The housing 7 and the connecting body 8 are connected by a crank 9. By rotating this crank 9,
As shown in FIG. 7, the connecting body 8 is configured to move in the housing 7 in a direction orthogonal to the axis of the through hole 1a. Therefore, by rotating the crank 9, the other end portions of the many elastic conductors 5 are simultaneously moved in the same direction. A drive mechanism for moving the other end of the elastic conductor 5 in a direction orthogonal to the axial direction of the through hole 1a is constituted by the housing 7, the connecting body 8 and the crank 9.

FIGS. 8 and 9 show a sixth embodiment, which is basically the same as the fifth embodiment. In this embodiment, the other end of the elastic conductor 5 is connected. It is fixedly connected to the body 8. In this case, as shown in FIG. 9, when the connecting body 8 is moved by rotating the crank 9, the degree of bending of the elastic conductor 5 becomes substantially S-shaped, similar to that shown in FIG. 2.
Therefore, in the sixth embodiment, the boosting effect is smaller than that of the fifth embodiment, and in order to obtain the same elastic contact force as in the fifth embodiment, the length of the pin 5 must be reduced. Need to be longer.

FIG. 10 shows a seventh embodiment.
Are provided with a plurality of rows of through holes 1a in the connection object 1 of
Similarly, holes 3a are provided in the second connection object 3 in a plurality of rows. The elastic conductors 5 are arranged in a plurality of rows corresponding to the through holes 1a and the holes 3a. A plurality of connecting bodies 8 are arranged in the housing 7 so as to correspond to each row of the elastic conductors 5, and the other end of the elastic conductor 5 is rotatably connected to the connecting body 8 for each row. Adjacent connectors 8 are driven in opposite directions. In the case where the elastic conductors 5 are arranged in one row, when the other end of the elastic conductor 5 is moved in a direction orthogonal to the axis of the through hole 1a, the first connection object 1 and the second connection object 3 Opposite forces act on each other, and the first connection object 1 and the second connection object 3 try to move in opposite directions. That is, in the first to sixth embodiments,
The guide pin 13 and the guide hole 33 also have a role of preventing a displacement between the two connection objects 1 and 3 when driving the other end of the elastic conductor 5. However, in the case of this embodiment,
Since two forces having opposite directions act on the two connection objects 1 and 3, respectively, these forces cancel each other. Therefore, when the rows of the through holes 1a and the like are even rows, the forces acting on the first and second connection objects 1 and 3 are completely balanced, and the first and second connection members 1 and 3 are balanced. In both cases, the force for moving in either direction does not work, and the force does not concentrate on the guide pin 13 and the guide hole 33. Therefore, in the case of the present embodiment, the guide pin 13 and the guide hole 33 , The first and second connection objects 1 and 3 are merely positioning means, and the guide pins 13 are not fatigued. Of course, the configuration in which the elastic conductors 5, the connecting bodies 8 and the like are arranged in a plurality of rows and the adjacent connecting bodies 8 are moved in the opposite direction is also applicable to the sixth embodiment shown in FIG. can do.

[0024]

According to the present invention, a pair of connection objects to be connected to each other are opposed to each other so that the through holes formed in these connection objects are opposed to the holes, and the elastic conductor is connected to the through holes. Is inserted into the hole, and the other end of the elastic conductor is moved in a direction perpendicular to the axial direction of the through hole, thereby connecting the two connection objects via one end of the elastic conductor. As a result, the driving force of the elastic conductor required to connect the two objects to be connected can be reduced, and the conduction distance can be shortened, so that it is possible to effectively cope with high-speed signals. is there.
