Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector device used for electrically connecting a plurality of circuit boards and an electronic device having a plurality of circuit boards electrically connected through the connector device.

[0002]

2. Description of the Related Art In recent years, various book-type portable computers that are easy to carry and have high functionality have been provided.
This type of computer includes a box-shaped housing having a keyboard, and a circuit board is housed inside the housing together with a CD-ROM drive device and a hard disk drive device.

By the way, since the housing of recent portable computers is designed to be compact, the space inside the housing becomes smaller and smaller, and the size of the circuit board tends to be limited. Therefore, conventionally, a plurality of small-sized circuit boards are vertically stacked inside the housing,
A computer having a configuration in which these circuit boards are connected to each other through a stacking connector has been developed.

The stacking connector used in this computer includes a connector plug and a receptacle into which the connector plug is detachably fitted. The connector plug has a synthetic resin plug body supported by one circuit board. The plug body has an elongated fitting hole, and a large number of first contact terminals are arranged in a line inside the fitting hole at intervals. The first contact terminal has a flat rectangular plate shape, and the first contact terminal is integrally molded with the plug body in such a posture as to follow the inner surface of the fitting hole.

Further, the receptacle has a receptacle body made of synthetic resin, which is supported by the other circuit board. The receptacle body has a fitting convex portion that is removably fitted into the fitting hole of the plug body, and a large number of second contact terminals are arranged in a line on the side surface of the fitting convex portion with a space therebetween. It is supported. The second contact terminal has a contact piece that is elastically deformable in a direction in which the second contact terminal comes into contact with and separates from the side surface of the fitting protrusion. The contact pieces are formed to have a width narrower than that of the first contact terminal, and the contact pieces are pressed against the first contact terminal when the fitting protrusion and the fitting hole are fitted to each other. It is supposed to do.

On the other hand, in this type of stacking connector, the pitch of the first and second contact terminals tends to become finer as the number of signals increases as the computer becomes more multifunctional and has a larger capacity. Therefore, the first contact terminals, which are particularly flat plate-shaped, are in a state in which both side edge portions thereof are adjacent to each other, and a partition wall is interposed between the adjacent first contact terminals. The partition wall is for preventing electrical conduction between the adjacent first contact terminals and is integrally formed on the inner surface of the fitting hole of the plug body.

[0007]

However, according to the above-mentioned conventional stacking connector, the first flat plate-shaped connector is formed.
Since the contact terminals are integrally molded with the plug body, the positions of these first contact terminals are fixedly determined. Therefore, in the state where the plug body and the receptacle body are fitted to each other, the contact pressure between the first contact terminal and the second contact terminal is secured only by the displacement amount of the contact piece, and these contact terminals are secured. The positional accuracy in the pitch direction depends only on the matching between the contact piece and the first contact terminal.

Therefore, if the first and second contact terminals are displaced in the pitch direction within the allowable error range,
Since the displacement amount of the contact piece naturally has an allowable error, the contact pressure between the contact piece and the first contact terminal varies and the reliability of the electrical connection is deteriorated.

Further, in the above-mentioned conventional connector plug, since the partition wall is interposed between the first contact terminals,
The thickness of these partition walls determines the pitch of the first contact terminals. Therefore, the partition wall hinders miniaturization of the pitch of the first contact terminals, and there is a problem that the connector plug becomes larger as the number of the first contact terminals increases.

The present invention has been made in view of the above circumstances. A first object of the present invention is to cause a displacement in the pitch direction between the contact portions between the first contact terminal and the second contact terminal. Even in the case of occurrence, this positional deviation can be absorbed, the contact pressure between the first contact terminal and the second contact terminal can be kept substantially constant, and the reliability of electrical connection can be improved. Is to get.

A second object of the present invention is to obtain a connector device which can further reduce the pitch of a plurality of contact terminals and can cope with an increase in the number of signals without increasing the size of the connector body.

A third object of the present invention is to reliably contact the contact terminals even if the pitch of the first and second contact terminals is made fine, and electrically connect a plurality of circuit boards. It is to obtain an electronic device whose reliability is improved. It is a fourth object of the present invention to obtain an electronic device which can prevent the connector body from increasing in size and can mount a large number of circuit components on a circuit board at a high density.

The first contact terminal and the second contact terminal are automatically deformed so that their deformation degrees are balanced with each other.
Even if the first and second contact terminals are displaced in the pitch direction, the contact pressure of these contact terminals can be kept constant.

Therefore, the deformation of the first and second contact terminals makes it possible to absorb the deviation in the pitch direction, and while ensuring a sufficient tolerance of the mounting positions of these contact terminals, a reliable contact state. Can be obtained.

According to claim 2, the first connector body according to claim 1 has a connector body made of synthetic resin, and the first contact terminal is supported by the connector body. It has a supporting part which has a flat plate shape.

According to this structure, since the supporting portion of the first contact terminal is simply a flat plate, the section modulus is smaller than that of the portion having the extending portion. Therefore, when the second contact terminal comes into contact with the extending portion of the first contact terminal, the first contact terminal is elastically deformed smoothly with the support portion as a fulcrum, and the first contact terminal is extended. No unreasonable force is applied to the contact portion between the second contact terminal and the second contact terminal.

According to a third aspect, the first contact terminal according to the first aspect has side edge portions adjacent to each other in the arrangement direction, and the side edge portions are non-conductive insulating layers. It is characterized by being covered.

According to this structure, it is not necessary to interpose a wall electrically insulating between the first contact terminals adjacent to each other, and the pitch of the first contact terminals can be made fine. . Therefore, the first connector main body can be made compact, and the number of first contact terminals can be increased without increasing the size of the first connector main body.

In order to achieve the above-mentioned second object, claim 4

Since it is electrically insulated by its own insulating layer, it is not necessary to interpose an insulating partition wall between adjacent contact terminals, and the pitch of these contact terminals can be miniaturized. For this reason, the connector body can be made compact, and the number of contact terminals can be increased without increasing the size of the connector body, and an increase in the number of signals can be naturally handled.

In order to achieve the third object, claim 5

In addition, the first contact terminals can be elastically deformed in the direction of coming into contact with and separating from the second contact terminal, and the first contact terminals are provided on both sides along the arrangement direction in the direction of approaching the second contact terminal. Has an extended extension It is characterized in that there.

In such a structure, when the first connector body and the second connector body are fitted to each other, the second contact terminal is inserted between the terminal portions of the first contact terminal, Elastically contacts the first contact terminal. At this time, if the first and second contact terminals are displaced in the pitch direction within the allowable error range, the second contact terminal comes into contact with the extension portion of the first contact terminal, and the first contact terminal Elastically deforms in a direction away from the second contact terminal. As a result, the first
The contact terminals and the second contact terminals are automatically deformed so that their deformation degrees are balanced with each other, and the contact pressures of these first and second contact terminals are kept constant, and

From this, even if the pitch of the first and second contact terminals is made finer, these contact terminals will surely come into contact with each other, so that the plurality of circuit boards housed in the inside of the housing are connected to each other. You can connect securely. Therefore, the reliability of the electrical connection is improved, and it is possible to easily cope with the increase in the number of signals accompanying the higher functionality of electronic devices.

Second and third fitting spaces 24 and 25 are formed between the side surfaces of these terminal support portions 23 and the inner surfaces of the outer walls 22a and 22b. The second and third fitting spaces 24, 25 are open toward the side opposite to the bottom wall 21.
And the plug body 7 in the third fitting spaces 24, 25.
The side walls 7b and 7c are detachably fitted.

Therefore, as shown in FIG. 3, the plug body 7 and the receptacle body 20 are coupled with each other in a state of being meshed with each other. Terminal support 23
A large number of accommodation recesses 27 are formed on each of the pair of side surfaces. The accommodating recesses 27 are arranged in a line in the longitudinal direction of the terminal supporting portion 23 with a space therebetween, and the pitch P2 between the adjoining accommodating recesses 27 is equal to the first contact terminal 1 described above.
It is defined corresponding to a pitch P1 of zero. Then, each accommodation recess 27 is opened in the bottom surface of the bottom wall 21.

A second contact terminal 28 is arranged in each accommodation recess 27 of the terminal support 23. The second contact terminal 28 is made of a metal material having excellent conductivity and is formed narrower than the contact piece 11 of the first contact terminal 10. The second contact terminal 28 has a contact piece 29 housed in the housing recess 27 and a lead portion 30 connected to the contact piece 29.

Stacking connector 3 having such a configuration
In, when the plug body 7 of the connector plug 4 and the receptacle body 20 of the receptacle 5 are fitted to each other, the contact piece 11 of the first contact terminal 10 and the contact piece 32 of the second contact terminal 28 face each other. Since the contact piece 11 is curved in an arc shape so as to project into the first fitting space 8, the contact piece 32 of the second contact terminal 28 is formed.
While entering between the extending portions 14a and 14b of the first contact terminal 10, the contact piece 11 of the first contact terminal 10
Contact

In this case, since the contact piece 32 is elastically movable in the direction orthogonal to the pitch direction of the first and second contact terminals 10, 28, the first and second contact terminals 10, 28 are formed. Even if 28 is displaced in the direction orthogonal to the pitch direction within the allowable error range, this allowable error is absorbed by the displacement of the contact piece 32.

On the other hand, the first and second contact terminals 10, 2
When 8 is displaced in the pitch direction within the allowable error range, the contact piece 32 comes into contact with any of the extending portions 14a or 14b of the contact piece 11, as shown in FIG. Then, since the extending portions 14a and 14b project toward the first fitting space 8 from the center portion in the width direction of the contact piece 11, the contact piece 10 supports the support portion as shown by the arrow in FIG. It tries to elastically deform in a direction away from the contact piece 32 with 13 as a fulcrum.

As a result, the first contact terminal 10 and the second contact terminal 28 are automatically deformed to a position where their deformation degrees are balanced with each other, and the contact piece 32 and the extending portion 14a or the extending portion 14a.

Contacting the first contact terminal 10,
Therefore, elastic deformation is smoothly performed with the fulcrum as a fulcrum, and an unreasonable force is not applied to the contact portion between the extension portion 14a or 14b and the contact piece 32. Therefore, the contact pressure of the contact portion can be kept substantially constant, and a reliable contact state can be obtained.

Also, the first and second contact terminals 10, 2
