Description

[Detailed description of the invention] This invention is a roll-type hinge connector, more specifically, a connector that connects two printed circuit boards, and after connecting both boards, one board rotates about the other board. Regarding the connector that allows you to do this.

An invention filed on March 27, 1980 (Showa
Patent Application No. 44935 of 1956, Japanese Patent Application Laid-open No. 158969/1983). In this prior art invention, two housings are made to face each other, their opposing surfaces are connected via a hinge so as to be flexible, and a flexible conductor is stretched between both housings to connect the electrodes in both housings with electricity. The present invention discloses a flexible connector that allows both housings to rotate through an angle of at least 45 degrees about a hinge.

The structure of the patent application mentioned above is complicated, especially the structure of the conductor of the connector, and it is not possible to connect or disconnect both boards with the connector at the desired rotation position. There is a disadvantage.

Taking these points into consideration, the main purpose of this invention was to create a roll-type hinge connector that has a simple structure, especially a simple structure of the contact conductor, and that applies almost no load to the rotating part of the contact conductor when rotating. It is about providing.

It is also an object of this invention to provide a roll-type hinge connector that is highly manoeuvrable and allows for easy attachment and detachment of boards in a pivoted position.

The purpose of this invention is to provide a roll-type hinge connector in which the contact conductors of both boards are connected via a connector, and no load is applied to the contact area of the contact conductors even when the connector is rotated. be.

Next, the best mode of the roll-type hinge connector of this invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view showing the state of the roll-type hinge connector 10 of this invention before connection.
0 consists of a male housing 12 made of an insulator and a female housing 14 also made of an insulator.

As is clear from FIGS. 1 and 2, the male housing 12 has one longitudinal side wall 16.
recesses 2 that are separated by partition walls 18 that are spaced at regular intervals along the
0 is set. An opening 22 is provided at the inner bottom of this recess 20, into which a leg 26 of an L-shaped male contact conductor 24 can be inserted. The head portion 28 of the contact conductor 24 is bent into an L-shape perpendicularly to the leg portion 26 and extends slightly above the bottom surface of the recess 20 in parallel to the bottom surface, with its front end terminating inside the recess 20. It's on. Male contact conductor 2
The leg portion 26 of No. 4 extends outward from the opening 22 of the housing 12, and after being attached to the housing, the leg portion 26 is passed through a predetermined portion of the first printed circuit board 30, and the conductor portion passing through the leg portion is soldered 32. By doing so, the male housing 12 is attached to the board 30.
to be fixed.

As shown in FIG. 1, the female housing 14 includes:
A hollow space 44 is formed at the intermediate portion of both end faces 40 facing each other in the longitudinal direction, and an insulator is inserted into the space 44 so as to be able to rotate. A roll member 46 made of aluminum is mounted.

The roll member 46 is a generally flat block body, and has cylindrical shaft portions 4 at both ends in order to rotatably attach it to the cavity 44 of the female housing 14.
8 is formed to protrude outward. on the other hand,
On both end surfaces 40 of the female housing 14,
An oval bearing opening 50 is provided to rotatably support the shaft 48, and a notch 52 is formed at the upper end of the bearing opening 50 in order to insert the shaft 48 into the opening 50 from above. It has been done.

The side edge of the roll member 46 on the male housing 12 side protrudes so as to be fitted into the male housing 12. In order to receive the roll member 46, the male housing 12 has a notch 34 formed in the partition wall 18 forming the recess 20 into which the side edge of the roll member 46 can be inserted.

Further, a cavity 54 is provided on the side edge of the roll member 46 at a position that coincides with the recess 20 of the male housing 12. In this space 54, a female contact conductor 5 is inserted.
6, and the female contact conductor 56 is
As shown in FIG. 3, there is a two-pronged contact portion 58 made of a thin elastic metal plate and configured to grip the head portion 28 of the male contact conductor 24, and a body portion extending in the longitudinal direction from the contact portion 58. 60, and a leg portion 62 bent at right angles from the body portion 60.

In order to insert the female contact conductor 56 into the roll member 46 so as to arrange the contact portion 58 in the cavity 54 of the roll member 46, the cavity 54 has an opening for inserting the body 60 of the contact conductor 56. 64
On the other hand, in order to fix the contact conductor 56 in the opening 64, it is preferable to provide an overhanging tongue 66 at the corresponding location. The body portion 60 of the female contact conductor 56 extends along the bottom surface of the cavity 44 of the female housing 14, and the legs 62 extend outwardly from an opening 68 provided in the bottom surface thereof. The outwardly extending legs 62 of the female contact conductor 56 attached as described above are passed through a predetermined portion of the second printed circuit board 70, and the penetrating portion is fixed to the board 70 by applying solder 72. The leg portion 62 of the contact conductor 56 has a tongue-like overhang portion 74.
Preferably, the leg portion 62 is configured to be secured to the opening 68 of the female housing 14 before the leg portion 62 is soldered.

The body 60 of the female contact conductor 56
is attached to the female housing 14 and the roll member 46 as described above, and when the roll member 46 is rotated, the cylindrical shaft portion 48 of the roll member 46 engages with the oval bearing opening 50 of the female housing 14. The length is such that the body 60 of the contact conductor 56 can curve along the arcuate edge 76 of the roll member 46 .

In order to rotate the roll member 46 to which the female contact conductor 56 is attached as described above, the center distance d of the oval opening 50 is set to d=πr/2 with respect to the radius r.

The roll-type hinge connector 10 of this invention is constructed as described above, so that the conductor 24 of the male housing 12 is soldered and secured to the first printed circuit board 30, and the female housing 12 is soldered to the first printed circuit board 30. and a female contact conductor 56 disposed on the roll member 46.
is soldered to the second printed circuit board 70, and the roll member 46 is fitted into the notch 34 of the male housing 12 as shown in FIG.
The head 28 of the male contact conductor 24 is held between the contact portions 58 of the female contact conductors 56, and the two can be electrically connected.

In this state, when the first printed circuit board 30 fixed to the male housing 12 is rotated in the direction of arrow A in FIG.
There is no change in the contact area with 6, and while maintaining that contact, move it from the position shown in Figure 2 to 4.
It can be rotated through 90 degrees to the position shown in the figure.

When the male and female connectors 12, 14 are rotated above,
The body 60 of the male contact conductor 56 moves by a distance d connecting the two center points of the oval opening 50, that is, with respect to its radius r, a distance set as d=πr/2.

Therefore, the moving distance depends on the radius r of the shaft portion 48 of the roll member 46, and if the radius r is small, the moving distance is short, but the deformation of the contact conductor 56 becomes large, but a load is applied during its rotation. The only part is the deformed part, and since this part sequentially moves along the arcuate edge 76 of the shaft part 48 as the roll member 46 rotates, the stress is constant.

In addition, the roll type hinge connector 1 of this invention
0, it is possible to attach and detach both the male and female housings 12, 14 at a desired rotational position.
