[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to a connector for electrically connecting stacked printed wiring boards. More specifically, the present invention relates to a low-profile stacking connector used for connecting printed wiring boards in a small and thin mobile terminal device represented by a mobile phone terminal, and a method of mounting the connector.

[0002]

2. Description of the Related Art A portable telephone terminal has, for example, a plurality of printed wiring boards stacked and arranged in a housing thereof.
The stacked printed wiring boards are interconnected by a stacking connector. There are various types of stacking connectors as described below.

Japanese Unexamined Patent Publication No. Hei 8-250243 discloses a direct contact type connector in which the upper and lower printed wiring boards 201 and 202 are directly electrically connected by one connector as shown in FIG. . That is, in the direct contact type connector of FIG.
Upper and lower printed wiring boards 201, 20 regulated by
2, the contact 203 of the contact 203 fixed to the lower substrate 201 by the fixing member 204 is electrically connected to the pad 205 provided on the upper substrate 202 by directly pressing the contact directly. . The direct contact type connector of FIG. 1 is a connector of a board length direction extending type in which a contact 207 and a pad 205 extend in a length direction of the boards 201 and 202.
7 does not slide on the pad 205. Therefore, a clean contact surface cannot be obtained between the contact 207 and the pad 205, and the contact 207 with respect to the pad 205 cannot be obtained.
However, there is a problem that the electrical contact is not stable. Pad 2
Although it is possible to obtain a stable electrical contact by performing a surface treatment of performing a nickel undercoating process and then performing a gold plating process on the nickel substrate 05, such a surface treatment requires a large cost. Further, since the surface of the upper substrate 202 on which the pads 205 are provided is usually contaminated with insulating impurities such as flux, there is a problem that the reliability of electrical connection is low. Furthermore, there is no lock mechanism for fitting a pair of connectors.

Japanese Unexamined Patent Publication No. Hei 8-250240 discloses that, as shown in FIG.
3 is provided, a header 304 is inserted into the through hole 303,
A socket 306 is provided on the lower printed wiring board 302,
A through-hole type connector that is electrically connected by fitting between a header 304 and a socket 306 is disclosed. That is, in the through-hole connector of FIG. 2, the fixed contact 305 provided on the inner surface of the header 304 is
Contact 308 of movable contact 307 protruding outward from
This is the configuration that comes into contact with For the through-hole connector, the header 3
04 and the socket 306 when the movable contact 3
07 is fixedly inserted into the fixed contact 305 from the bottom up, that is, in the thickness direction of the printed wiring board while sliding.
05, a clean contact surface can be obtained. Further, the connector can be reduced in height by the amount embedded in the printed wiring board 301. However, in the through-hole type connector, since the through-hole 303 is provided in the printed wiring board 301, it is necessary to design the circuit while avoiding the through-hole 303, so that the degree of freedom in circuit design is restricted, There is a problem that the mounting efficiency is reduced because the front and back sides cannot be mounted at the hole 303 portion.

[0005] JP-A-2000-133344 discloses that
As shown in FIG. 3, a female connector 401 and a male connector 40 are provided for upper and lower printed wiring boards (not shown), respectively.
3, a two-piece connector is described which is electrically connected by fitting the female connector 401 and the male connector 403. That is, in the two-piece connector of FIG. 3, the contact 422 of the movable contact 421 protruding from the male connector 403 toward the center comes into contact with the fixed contact 423 provided inside the female connector 401. Similarly to the through-hole connector described with reference to FIG. 2, when the female connector 401 and the male connector 403 are fitted, the contact 422 of the movable contact 421 moves downward from the fixed contact 423, that is, in the thickness direction of the board. Since the male connector 403 is inserted into the female connector 401 while sliding, a clean contact surface can be obtained at the contact 422 and the fixed contact 423. However, in the two-piece connector of FIG. 3, the shorter the connector is, the shorter the sliding distance of the movable contact 421 with respect to the fixed contact 423 becomes. There is a problem that the surface cannot be obtained, and the electrical contact resistance of the contact becomes unstable. Further, a mechanism for locking the female connector 401 and the male connector 403 when they are fitted is not provided.

The through-hole type connector and the two-piece type connector shown in FIGS. 2 and 3 have the following common problems because the contacts slide in the thickness direction of the upper and lower substrates when the connectors are fitted. ing. That is, the connector requires a certain contact sliding length to stabilize the electrical contact between the contact and the fixed contact, and the contact comes into contact with the fixed contact with a predetermined spring force. Requires a certain spring length. Therefore, the connector of the board thickness direction sliding type in which the contact slides in the thickness direction of the board when the connector is fitted shown in FIGS. 2 and 3 requires a connector thickness corresponding to the sliding length of the contact, There is a problem that it is difficult to reduce the thickness of the connector, that is, to reduce the height. Further, since separate connectors are used as the male connector and the female connector, it is necessary to manufacture the male connector and the female connector, respectively, so that there is a problem that the cost of manufacturing the connector is relatively high.

[0007]

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a connector which satisfies both a low resistance and a low height electrical contact. Another object of the present invention is to provide a connector that can be securely fitted by a low-cost connector and a lock mechanism.

[0008]

SUMMARY OF THE INVENTION In order to solve the above technical problems, the present invention is directed to a contact connector, wherein a contact elastically supported on a housing of one connector is provided on a housing of the other connector. The basic feature is that one connector is mounted on the other connector so as to elastically slide on the part.

More specifically, this connector has a plurality of conductive first contacts having elastically supported contacts, a plurality of conductive second contacts having contact portions, and a connector when the connectors are mounted. An insulating housing having an abutting guide surface which is abutted and slidably guided, wherein a contact portion of each second contact is arranged at a position corresponding to the contact and extends along the abutting guide surface. Existing connector, wherein one connector is attached to the other connector while the contacts of each first contact resiliently slide on the contact portion of each second contact. I do.

According to the connector having the above-described structure, low-resistance electrical connection and reduction in height can be obtained as follows. That is, the connector mounted on the printed wiring board is mounted parallel to the mounted printed wiring board (in the connector mounting direction). The connector is positioned so that the contact of the conductive first contact of one connector faces the contact portion of the conductive second contact of the other connector. Then, the contact elastically supported by the housing is pressed against a contact portion extending parallel to the contact guide surface. At the same time, the contact point of the first contact is translated on the contact portion along the contact guide surface. As a result, the contact of the conductive first contact elastically supported in one connector slides elastically on the contact portion of the second contact in the other connector.

When the contact of the first contact slides on the contact of the second contact, the contact elastically supported by an appropriate spring force rubs the surface of the contact of the second contact, The very thin high resistance coating formed or adhered to both the contact of the conductive first contact and the contact of the conductive second contact is stripped off. As a result, a low-resistance clean surface existing inside the conductive contact is exposed. Therefore, the first contact and the second contact having the low-resistance clean surface exposed to each other make a stable low-resistance electrical connection between the conductive first contact and the conductive second contact. Obtainable.

In order to stabilize the electrical contact between the contact and the contact, it is necessary to slide the contact with a certain length (for example, 0.1 to 1 mm) with respect to the contact.
In the connectors of FIGS. 2 and 3 described in the related art, the contacts are slid in the thickness direction of the printed wiring board. On the other hand, in the connector of the present invention, since the connector is mounted in the length direction of the printed wiring board, the contact slides in the length direction of the printed wiring board. That is, since the contacts do not slide in the thickness direction of the printed wiring board, the height of the connector can be reduced and the height of the connector can be reduced. Therefore,
By applying the low-profile connector to the portable terminal device, the interval between the stacked printed wiring boards is reduced, and the portable terminal device can be reduced in size and thickness.

In the above connector, the first contact guide surface of one connector abuts on the second contact guide surface of the other connector, and the connector moves in parallel along the second contact guide surface. Is attached to the other connector. In this case, even if an excessive force is applied to the connector when the connector is mounted, the first contact guide surface and the second contact guide surface come into contact with each other, and excessive force is applied by the contact guide surface. I can take it. Therefore, an excessive force is prevented from acting on the contact point of the first contact and the contact portion of the second contact, so that the first contact and the second contact are largely deformed (buckling occurs). And will not be damaged.

Preferably, each of the first contact guide surface and the second contact guide surface is inclined at the same angle with respect to the bottom surface of the housing.

When a mounting force parallel (connector mounting direction) is applied to the connector pair on the printed wiring board on which the connector is mounted, first, the first contact guide surface of one connector is moved to the second contact guide surface of the other connector. Contact the contact guide surface. Then, the bottom surface of the housing (that is, the connector mounting direction)
, The connector mounting force is divided into a normal force and a parallel force with respect to the inclined contact guide surface. The normal force is used for the contact of the first contact to press the contact of the second contact vertically, and the parallel force is applied when the contact of the first contact is applied to the contact of the second contact. Used to slide. Therefore, the connector mounting force is used for the contact of the first contact to slide on the contact portion of the second contact. Therefore, the connector is simply moved in the connector mounting direction without performing an operation of once moving the connector toward the contact guide surface and then moving the connector in parallel along the contact guide surface. The contacts of the contact can slide on the contact of the second contact.

The connector may be a female connector and a male connector which can be distinguished from each other. However, it is preferable that the connectors have the same shape without any male and female from the viewpoint of manufacturing cost and the like.

Preferably, the housing further includes an engaging portion extending in the connector mounting direction, and an engaging receiving portion for receiving the engaging portion. When one connector is mounted on the other connector, as described above, the contact of the first contact of one connector slides elastically on the contact portion of the second contact of the other connector. At the same time, the engagement portion of one connector engages with the engagement receiving portion of the other connector. That is, the engaging portion extending in the connector mounting direction engages with the engagement receiving portion of the other connector in the connector mounting vertical direction. Therefore, this engagement structure functions as a lock mechanism when the connector mounting vertical force is applied, thereby preventing the connector from being accidentally disconnected.

The contact portion of the second contact can be elastically supported, like the contact of the first contact.
Preferably, the contact portion of the second contact is fixed so as not to move with respect to the second contact guide surface. If both the contact of the first contact and the contact of the second contact are elastically supported, there is a possibility that the electrical contact property of the contact may not be stable due to variations in the contact force of the contact and the contact. On the other hand, if the contact of the first contact has an elastic support structure and the contact of the second contact has a fixed structure,
The variation in the contact force of the contact with the contact portion is reduced, the electrical contact property of the contact is stabilized, and the variation in the electrical contact resistance is reduced.

Preferably, the conductive first contact is formed by bending a resilient spring piece of metal or the like. The spring piece is bent into various shapes such as, for example, U-shape, V-shape, W-shape, U-shape, and L-shape. In the spring pieces bent into various shapes, the base end fixed to the housing serves as a fulcrum of the spring, and the free-moving distal end becomes the final point of action, and the distance from the fixed base end to the free distal end is increased. The bent length acts as the spring length. As described above, since the spring of the bent type can have a longer spring length than the spring of the straight shape, the spring constant of the spring piece can be made smaller than that of the straight spring. Thereby, a wide spring displacement area for obtaining a necessary and sufficient contact force can be secured. Therefore, stable contact (force) can be obtained between the contact and the contact portion.

The contact of the first conductive contact may have a structure in which a conductive protrusion is formed on a conductive spring piece. However, preferably, a conductive spring piece of metal or the like is bent into a V-shape or the like. It forms by doing. The contact bent in a V-shape or the like is bent when the first contact is bent.
Since it is only necessary to add a bending step for forming a character shape or the like, there is almost no increase in manufacturing cost.

It is preferable to have a suction surface for surface mounting on the side of the contact guide surface of the housing. When the connector is mounted on the printed wiring board by the automatic mounting machine, the suction chuck of the automatic mounting machine uses the suction surface. And the connector can be mounted on the printed wiring board.
