BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotary structure type modular jack connector.

[0002]

2. Description of the Related Art A so-called modular jack connector is used to connect a communication device terminal such as a telephone or a facsimile machine to a telephone line side via a line cord. In such a case, for example, regarding the relationship between the telephone cord and the handset, the cord is twisted every time the handset is rotated when the telephone is used. At this time, if the modular jack connectors and plugs used to connect the cord to the handset are not structured to release the twist of such cord, the cord will be twisted badly during long use. It will end up getting tangled.

In order to solve such problems of twisting and entanglement of cords, rotary structure type modular jack connectors have been developed and used. An example of this type of rotary structure type modular jack connector is disclosed in Japanese Patent Laid-Open No.
The one disclosed in Japanese Patent Publication No. 2-154483 and the actual Kaihei 5
There is one disclosed in Japanese Patent Laid-Open No. 11350.

The rotary electric connector device disclosed in Japanese Patent Laid-Open No. 62-154483 has a modular plug fitted to a modular jack arranged on the handset side, and a modular plug fixed to the modular plug on the outer periphery. A main shaft having a contact ring, a housing having a modular jack contact rotatably mounted around the main shaft and in rotary contact with the contact ring of the main shaft, and a cord fitted to the housing. It has a mating modular plug to connect with. In this conventional rotary electric connector device, since the mating modular plug to which the cord is connected can rotate around the main shaft together with the housing, the cord is not twisted or entangled even when the handset is rotated. .

The modular jack disclosed in Japanese Utility Model Laid-Open No. 5-11350 has a cylindrical opening provided in a modular jack body fixedly mounted on a substrate, and rotatably inserted into the cylindrical opening. , A cylindrical rotating portion having an electric engaging portion with the plug and a mechanical engaging portion, and a means for electrically engaging between the electric engaging portion and the modular jack body. . Also in this modular jack, when the modular plug to which the cord is connected is fitted to the cylindrical rotating part, the modular plug can rotate together with the cylindrical rotating part in the cylindrical opening of the modular jack body. Even if a rotational force is applied to, it can escape
The cord will not be severely twisted or tangled.

[0006]

The conventional rotary structure type modular jack connector described above is effective in preventing the twisting and entanglement of the cord, but has the following problems. First, JP-A-62-15448
In the rotary electric connector device of Japanese Patent Laid-Open No. 3 publication, since the jack structure portion and the plug structure portion are connected in the axial direction, the outer dimension in the axial direction inevitably becomes large. Further, since there is only one rotary contact point between the contact ring of the main shaft and the modular jack contactor, the contact of the contact point in the rotating part is unstable. Furthermore, even if the components are roughly divided, there are three parts: modular plug, spindle, and housing.
The structure is complicated and processing is difficult,
There are many contact points, and electrical loss will increase.

In the modular jack disclosed in Japanese Utility Model Laid-Open No. 5-11350, the number of parts is two, that is, the modular jack main body and the cylindrical rotating part, and although the structure is simple, the cylindrical rotating part is simple. The conductive pattern as a contact ring is formed around the large outer diameter of the cylinder. Even if the rotating contact pressure acts on these conductive patterns, the rotation of the cylindrical rotating part is not so smooth. It doesn't. Further, in this conventional modular jack, since no means for preventing the axial movement of the cylindrical rotating part is particularly provided, when a tensile force acts on the cord, a problem occurs in the electrical contact part. Will end up. Further, in the structure of this conventional modular jack, in order to stabilize the electrical contact with the contact ring, the contact pressure to the contact ring is increased, or the number of contact points is not one but two on both sides. However, since the outer diameter of the contact ring is large, the rotation of the cylindrical rotating portion is not so smooth.

An object of the present invention is to provide a rotary structure type modular jack connector which solves the above-mentioned conventional problems.

In such a fitted state, when a twisting force is applied to the cord 2 and a rotational force is applied to the plug 10,
Since the plug 10 can freely rotate in the connector body case 210 together with the rotating part insulating case 240, the twist of the cord 2 is immediately released, so that the cord 2 can be twisted or entangled even during long-term use. There is nothing to do.

FIG. 43 is a schematic view showing a connecting portion between a rotating portion insulating case 240A and a connector body case 210A of a rotary structure type modular jack connector as still another embodiment of the present invention. Other components of the rotary structure type modular jack connector of this embodiment are shown in FIG.

Therefore, the number of parts can be reduced and the cost can be reduced.

[0053]

The rotary structure type modular jack connector of the present invention comprises a connector body case having a very simple structure and a rotating part insulating case having a very simple structure.
The overall structure is very simple, easy to assemble, and inexpensive.

The outer diameter of the rear rotary shaft of the rotary insulating case can be made very small, and a rotary ring or a rotary disk can be mounted on the rotary shaft and sandwiched from both sides of the rotary ring or rotary disk to contact the contact portion of the board mounting terminal. With the structure in which the contacts are brought into contact with each other, it is possible to reduce the contact of the contact portion due to the rotation and improve the contact performance.

By providing the pressing plate or the pressing cover, it is possible to easily assemble the board mounting terminals and the like, and it is possible to prevent the contact portion from being exposed, resulting in contact failure due to adhesion of dust or the like. It can be prevented. Also,
Since the pressing plate or the pressing cover can be used to prevent the rotating part insulating case from moving in the axial direction, stable rotational contact can be maintained without increasing the number of parts.

By making the outer diameter of the rear rotary shaft considerably smaller than the outer diameter of the front part of the rotating part insulating case, the contact pressure of the contact part of the board mounting terminal with respect to the rotating ring or the rotating disk is sufficient. Even if the size is selected, the rotating part insulating case can be rotated relatively smoothly, so that the twisting force applied to the cord can be immediately released.

As in the embodiment described with reference to FIG. 25, if a through hole for receiving the tip of the contact portion of the board mounting terminal is formed in the holding plate, the contact portion of the board mounting terminal can be surely placed in the correct position. To prevent it from deforming,
Since the tip of each contact portion can be visually observed from the outside through the through holes, it is possible to confirm whether or not the board mounting terminals are properly arranged.

If the connecting portion of the jack contactor is brought into contact with the inner side of the rotating ring or the rotating disk, the number of contact portions can be minimized and the electrical loss can be minimized. The structure of the child and the rotating ring or the rotating disk can be greatly simplified.

In the embodiment as described with reference to FIGS. 1 to 25, if the positions of the contact portions on both sides of the board mounting terminal are staggered, the formation of the terminal itself is facilitated. Also, electrical contact with the rotating ring can be made better and stable.

In particular, regarding the embodiment described with reference to FIGS. 26 to 43, it is easy to arrange the board mounting terminals, which come into contact with each other so as to sandwich the rotating disk, in a staggered arrangement. It is easy to reduce the size in the direction. Further, when assembling the connector, it is only necessary to mount the rotating part insulating case, on which the jack contactor and the rotating disk are mounted, from the bottom surface of the connector body case, so that the assembly is very easy and the number of assembling steps is reduced.

In the embodiment described with reference to FIGS. 1 to 25, the structure of the rotary ring mounted on the rear rotary shaft of the rotary insulating case is such that the ring is truly ring in order to stabilize the contact with the board mounting terminal. Since it is necessary to form the rotary ring by cutting, the production cost of these rotary rings must be relatively high. Further, it is relatively difficult to perform reliable positioning when attaching the rotary ring to the rear rotary shaft. Also, when assembling the connector, the contact part on both sides of the board mounting terminal is widened, and then the rotating part insulating case with the jack contactor and the rotating ring is assembled into the connector body case, which is a relatively poor assembly workability. . Furthermore, in the form of mounting the board mounting terminal to the connector body case, it is necessary to mount the flat surface of the press of the board mounting terminal parallel to the axis and to bifurcate the board mounting terminal. Have a relatively large length in the longitudinal direction because they are arranged in a straight line next to each other.

On the other hand, according to the configuration of the embodiment described with reference to FIGS. 26 to 43, not only the jack contact and the board mounting terminal but also the rotating disk, that is, all the terminals can be manufactured by the press. Therefore, it can be made cheaper. The rotary disc can be attached to the rear rotary shaft by mounting the rotary disc in a slit groove formed in the rear rotary shaft for easy and reliable positioning.
When assembling the connector, the rear rotary shaft to which the rotary disc is attached is assembled to the main body case, and then the board mounting terminal is incorporated into the main body case, whereby the assembling workability is good. Further, since the rotary disk and the board mounting terminal mount the flat surface of the press in a direction perpendicular to the rear rotary shaft, the length dimension in the longitudinal direction can be made smaller.
