[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector, and more particularly to a connector having a rotatable connection portion.

[0002]

2. Description of the Related Art For example, in a personal computer 10 shown in FIG. 17, a main body 11 and a display section 12 are separate members, and a connection section is connected by a rotatable connector 20 therebetween.

The connector 20 used here has, for example, a configuration as shown in FIGS.

The connector 20 shown in FIG. 1 includes a stator 22 having a stator contact 21 mounted thereon and a rotor 24 having a rotor contact 23 mounted thereon.

[0005] The stator 22 and the rotor 24 are rotatably connected to each other in directions indicated by arrows B ₁ and B ₂ around a point A.

One end of the stator contact 21 is bent at an acute angle, and the tip of the stator contact 21 is bent inward to protrude downward in FIG. 15 to form a contact portion 21C. The contact portion 21C has an effect as a leaf spring at the same time due to its configuration. Also, the rotor contact 23
Has a contact portion 23C formed by bending one end side around the point A.

The contacts 21 and 23 are electrically connected by contacting each other at contact portions 21C and 23C. The other ends of the contacts 21 and 23 are connected to the main body 1 of the personal computer 10 respectively.
1 and the display unit 12 to electrically connect them.

In the state shown in FIG. 16, the contact portions 21C and 23C of the respective contacts are separated from each other.
1 contrast obtained by substantially 144 degrees rotation in the direction of arrow B ₂
In the state of No. 5, the contact portions 21C and 23C of the contacts are
They are in contact with each other. The state shown in FIG. 15 is a state in which the contact portion 23C presses the contact portion 21C in the direction of point A. Contact portion 2 having the effect of a leaf spring against this pressing force
1C slightly bends in the direction of point A, and exerts an action of pushing back against the contact portion 23C in an attempt to restore the bending. This pushing force, that is, the contact pressure,
1C and 23C are reliably connected electrically.

[0009]

In recent years, there has been a demand for miniaturization of personal computers and the like, and in particular, a reduction in thickness.

That is, for example, the personal computer 10 shown in FIG.
And can be folded by being superimposed on the main body 11 by turning in the direction of, and the portability can be improved by reducing the thickness.

In order to reduce the thickness, the display unit 1
The connector 20 needs to be downsized at the same time as the thickness of the connector 2 and the body 11 are reduced. Here, in the connector 20 described above, it is necessary to shorten the protruding portion of the contact portion 21C of the stator contact 21 in order to reduce the size.

However, structurally, if the projecting portion of the contact portion 21C is shortened, the effect of the contact portion 21C as a leaf spring is reduced, and the contact portion 21C is hardly bent. As a result, the contact portions are likely to be worn, and the contact portions 21C, 23
C may interfere with each other's electrical connection.

Therefore, with this configuration, it is difficult to reduce the size.

Thereby, one end on the lower left side of FIG. 4 of the curved sliding contact portion 31C is supported by the stator mold 35, and the sliding contact portion 31C has an effect as a leaf spring.

Next, the rotor 34 is
3 is inserted into the rotor mold 36 from below in FIG. At this time, the protrusion 33T of the rotor contact 33
Is pressed into the support hole 36T of the rotor mold 36 to fix the rotor contact 33. Thereby, one end of the lower part of the contact part 33C of the rotor contact 33 in FIG. 4 is supported by the rotor mold 36, and the contact part 33C has an effect as a leaf spring.

In the stator 32 and the rotor 34 separately assembled as described above, the shaft portions 35S provided at both ends of the protrusion 35H of the stator mold 35 are provided at both ends of the curved portion 36R of the rotor mold 36. Bearing 36G

The external contacts 41 (41 ₁ , 41 ₂ , 41 ₃ , 41) of the external connector 40 connected to the main body 11 of the computer 10
...) is inserted. By this insertion, the external contact 41 and the statuser contact 31 are connected to the external contact portion 31D.
Are mutually electrically connected via, this is found Contacts 4
The main body 11 and the statuser 32 of the personal computer 10 are electrically connected to each other via the first and the first 31.

Further, the display section 1 of the personal computer is connected to the external contact section 33D of the rotor contact 33.

Next, the operation of the contact portions of the connector 30 will be described with reference to FIGS.

FIG. 1 shows a display unit 12 of a personal computer 10 to which a connector 30 is applied.
State of being awakened from 1, i.e. shows a state in use of the personal computer 10, FIG. 2 is substantially 144 rotor 34 about the point A from the state of FIG. 1 in the direction of arrow B ₁
And the display unit 12 is
Indicates a folded state, that is, a state at the time of carrying.

1 and 2, the rotor contact 33
33C ′ indicated by a broken line indicates a state before the rotor 34 is mounted on the stator 32, that is, a state in which no external force is applied to the contact portion 33C of the rotor contact 33.

As shown in FIGS. 1 and 2, compared to FIG.
In FIG. 1, the flexure of the contact portion 33C of the rotor contact 33 is larger. This is because the substantially circular center of the curved sliding contact portion 31C is slightly shifted upward in FIG. 1 from the center A of the rotation of the rotor 34. Therefore, in the state of FIG. 1, the contact pressure between the contact portions 31C and 33C due to the repulsive force of the leaf spring with respect to the amount of bending is larger. Due to this contact pressure, the mutual contacts 31, 3
3 electrical connections are made reliably.

In FIG. 2, the above contact pressure is smaller than in the state of FIG. 1, and the electrical connection may be insufficient. However, as shown in FIG. 2, the state of FIG. Since no electrical connection is required, there is no problem.

[0050]

By this effect, it is possible to secure the electrical connection during use, and to reduce the contact pressure when carrying, that is, when not in use, to minimize the wear of the contact portion.

FIGS. 13 and 14 show states corresponding to FIGS. 1 and 2 of the first embodiment, respectively. That is, FIG. 13 shows a state when the personal computer 10 to which the connector 50 is applied is used. FIG. 14 shows a state when the mobile phone is carried.

The connector 50 of the second embodiment has a
The lower part of one end of FIG. 13 of the contact portion 51C of the contact 51 is supported in Suteita mold 55, similar to the contact portion 31 C of Suteita contacts 31 of the connector 30, an effect as a leaf spring. Further, a protruding portion 51U is formed near the tip of the contact portion 51 by bending.

Contact portion 53C of rotor contact 53
Are curved and fixed to the inner wall surface of the curved portion 56R of the rotor mold 56. Therefore, it does not have the effect of the leaf spring. When the connector 50 is used as shown in FIG.
14 are separated from each other at the time of carrying in FIG. In other words, when they are not used, they are not brought into contact with each other, thereby minimizing wear of the contact portions. Also, the projection 51U on the statuser contact 51
Is changed for each pair of contacts of the plurality of stators and the rotor, so that the contact portions of the rotor 54 and the stator 52 contact each other individually for each pair of the contacts of the plurality of stators and the rotor. The relative angles of each other can be changed.
