Description

[Detailed description of the invention] This invention relates to a plug used for example in audio equipment or communication equipment, and particularly aims to provide a plug whose cord pulling direction can be changed to any angle with respect to the axis of the plug body. It is something.

<Conventional Description> For example, a plug for connecting a headphone or a microphone to a device is generally divided into two types: one in which the cord is pulled out in the plug insertion/removal direction, and the other in which the cord is bent at 90 degrees with respect to the plug insertion/removal direction. Conventionally, this cord pulling direction is fixed for each plug, which may make it difficult to use in some cases.

<Purpose of the invention> This invention aims to provide a plug that allows the cord pulling direction to be freely changed.

<Summary of the invention> This invention connects the insulating bodies attached to the plug body so that they can rotate freely with a slope of approximately 45 degrees, and by connecting the slopes, the direction in which the cord is pulled out can be bent at 90 degrees. It is configured so that it can be made straight or freely selected.

<Example of the invention> Fig. 1 shows an example of the invention. In the figure, 1 indicates the plug body. A first insulating body 2 is attached to the rear end of the plug body 1. This first insulating body 2 is composed of a cylindrical body, and the rear end side is approximately parallel to the axis.
It has an inclined surface 3 inclined at 45 degrees.

A second insulating body 4 is provided on the rear end side of the first insulating body 2.
Attach it so that it can rotate freely. A cord 5 is inserted into the second insulating body 4 from the rear end side through a cord protector 9, and an inclined surface 6 inclined at 45 degrees with respect to the axis is formed on the front end side. The first insulating body 2 and the second insulating body 4 are connected at surfaces 3 and 6 which are inclined at 45 degrees to each other, and are rotatably connected to each other by a hollow shaft 7. The hollow shaft 7 is molded integrally with the second insulating body 4, as shown in FIG. The tip of the cord 5 is led out through the center hole of the hollow shaft 7, and the cord 5 is connected to the plug body 1. The second insulating body 2 is molded in half as shown in FIG. pinch. The second insulating bodies 2 can be welded together using, for example, an ultrasonic welder.

The hollow shaft 7 has a flange portion 7a at its tip,
This flange portion 7a engages with a groove 8 formed in the first insulating body 2, and the first and second insulating bodies 2 and 4 are rotatably coupled. On the other hand, a protrusion 7b is formed on the flange portion 7a, and the rotation range of the protrusion 7b within the groove 8 formed in the first insulating body 2 is restricted to 180 degrees. Further, a protrusion 6a is formed on one of the inclined surfaces, for example, the inclined surface 6, and recessed holes 3a and 3b are formed in the other inclined surface 3 facing 180 degrees, and the engagement between the protrusion 6a and the recessed holes 3a and 3b allows the angle of 180 degrees A click feeling is obtained at the rotational position of .degree., and the rotational position is maintained.

<Operations and Effects of the Invention> According to the plug of this invention explained above, by rotating the second insulating body 4, the cord 5 can be pulled out in a direction bent at 90 degrees as shown in FIG.
As shown in FIG. 4, it can be changed to a state in which it is pulled out in the same axial direction as the plug body 1. Therefore, it is convenient to be able to select the most suitable cord pulling direction for the usage situation during actual use. Further, according to the above-described structure, the cord 5 is only twisted. Cords are generally more resistant to twisting.
Therefore, even if the second insulating body 4 is made rotatable, a highly durable plug can be provided.

<Other embodiments of the invention> In the above, an example in which only the first insulating body 2 is divided into two parts has been described, but as shown in FIG. 5, both the first and second insulating bodies 2 and 4 are divided into two parts. It can also have a split structure. Furthermore, the method of combining the first and second insulating bodies 2 and 4, which are divided into two halves, is not limited to welding using an ultrasonic welder, but may also be performed by engaging the protrusion 11 and the groove 12 as shown in FIG. It can also be a structure.
