Description

[Detailed Description of the Invention] This invention relates to a connector to which a connecting cord is attached.

By attaching connectors to each end of a cord and using multiple such cords to connect each connector to a number of corresponding electrical devices,
BACKGROUND OF THE INVENTION In some cases, a large number of electrical devices are electrically connected by a large number of cords to operate the electrical devices. For example, in a broadcasting studio, an orchestra and a synthesizer can be used together, mixing psychedelic sounds created by the synthesizer with natural sounds, or even creating a four-channel sound field in which the sounds dance around the audience seats. Special sound effects may be created. In such cases, it is necessary to configure a large number of channels between various electrical devices such as a large number of mixers, amplifiers, and speakers, which increases the number of cords used to connect these electrical devices. However, it becomes necessary to connect electrical devices located a considerable distance apart. Moreover, in this case, for example, it is necessary to check on the mixer which sound source the cords connected to each connection end come from, and to connect them without making any mistakes.

As the number of cords connected between each electrical device increases and the cords become interconnected,
It becomes difficult to determine which cord is connected between which connection ends of which electrical device. In such cases, it is not easy to connect a large number of cords between predetermined connection ends of a predetermined electrical device without error.
Therefore, in such cases, a person in charge of each electrical device should be designated, and the person in charge should communicate with these persons to make the connections between the electrical devices.
Testing must be carried out to obtain the final desired acoustic effect.

Conventionally, in order to make complicated connections between a large number of electrical devices without error, a method has been used in which colored tapes of colors corresponding to the cord are attached to the connector attachment portions at both ends of the cord. In other words, by attaching colored tape of the same color to the connector attachment parts at both ends of the cord, it is possible to avoid mistakes by connecting the cords with the same colored tape attached to the specified terminals of the electrical devices to be connected at the connector parts. There are fewer cords to connect. However, as the number of electrical devices connected increases, and the number of cords connecting them increases, resulting in interconnected connections, it becomes difficult to prevent incorrect connections by simply displaying them with color tape. becomes.

This invention solves the difficulties of the conventional method mentioned above. For example, by connecting to a cord and using it, the number of connected electrical devices increases, the number of cords required for connection increases, and the connection between these increases. To provide a connector that can connect cords without error even in a complicated state. In other words, with the connector of this invention, it is possible to stably set a unique display by simple operation while connected to the cord, and it is possible to stably set a unique display to a specified connection end of an electrical device that corresponds to this display. This makes it possible to connect the cord without error.

In the connector of this invention, a cover ring is rotatably attached to the outer circumference of the connector base, and at least one of a character and a symbol is formed along the circumference of the connector base opposite to the inner circumference of the cover ring. There are multiple types of markings.
In this case, the symbols include symbols other than letters, such as figures and colors. On the other hand, display means is provided between the cover ring and the circumferential surface of the connector base for selectively displaying these plural types of displays.

Hereinafter, the connector of this invention will be explained in detail based on the embodiments using the drawings.

FIG. 1 is an assembly diagram showing the configuration of an embodiment of this invention, and is an example in which this invention is constructed as a so-called plug type connector.

The plug body 11 is made of a conductive material and has a rod shape, and has a curved portion 12 formed at its tip so that it can be easily inserted into a predetermined insertion hole of an electrical device to be connected. If necessary, the surface of the plug body 11 is plated with gold. An insulating washer 13 is attached to the circumferential surface of the plug body 11 in the vicinity of this spherical portion 12.
is installed and fixed. The diameter of the plug body 11 is enlarged on the side opposite to the curved part 12, and a cylindrical part 14 is integrally formed therein. A cylindrical connector base portion 15 is formed continuously from the columnar portion 14 .

A notch 16 is formed in a part of the circumferential surface of the connector base 15 in the axial direction. A connecting piece 17 is provided within this notch 16 and is electrically connected to the curved portion 12 . Further, one end of the core wire of the cord inserted into the connector base 15 from the opening side of the cylindrical connector base 15 is configured to be electrically connectable to the connecting piece 17.

The outer diameter of the cylindrical portion near the opening surface of the connector base 15 is slightly enlarged to form an edge ring 2.
1 is formed. A cover ring 18 is rotatably attached to the outer periphery of the cylindrical connector base 15 on the end side of the edge ring 21. The cover ring 18 is formed into an annular shape with an inner diameter slightly larger than the outer diameter of the connector base 15, and has projections and depressions 19 formed on its outer peripheral surface to facilitate rotation using fingers.

Further, in this invention, at least one of a character and a symbol is printed along the circumferential surface of the connector base 15, facing the inner circumferential surface of the cover ring 18, which is rotatably attached to the outer circumference of the connector base 15. Multiple types of displays consisting of . The embodiment is an example in which a plurality of types of numbers are displayed in a line along the outer peripheral surface of the connector base 15, and numbers 0 to 8 are displayed on the outer peripheral surface of the area of the connector base 15 where the cover ring 18 is attached. A display label 20 with a mark attached thereto is fixed.

The cover ring 18 is attached to the outer periphery of the connector base 15 as follows. That is, the toric-shaped spring body 2 is placed so as to cover the display label 20 portion fixed to the connector base 15.
2 is first press-fitted onto the outer periphery of the connector base 15 from its open surface side. This spring body 2
A protrusion 23 is formed on the inner peripheral surface of the spring body 22, and this protrusion 23 engages the connector base 15 of the spring body 22.
By rotating around the connector base 15, the display label 20 portion of the connector base 15 and the edge ring 21 are configured to elastically engage with a concavo-convex portion 24 formed on the outer periphery thereof. In this way, the cover ring 18 is press-fitted onto the outer peripheral surface of the spring body 22 attached to the connector base 15 from the open surface side of the connector base 15 .

By fitting the cover ring 18 onto the outer circumferential surface of the spring body 22, the cover ring 18 can rotate around the connector base 15 together with the spring body 22 due to the elasticity of the spring body 22. Further, during this rotation, the protrusion 23 of the spring body 22 elastically engages with the uneven portion 24 formed on the connector base 15, and the cover ring 18 is rotated with a click feeling for each unit angle of rotation. be able to. The arrangement positional relationship between the display label 20 and the uneven portion 24 is set so that the unit angle of this rotation corresponds to one display range of a plurality of types of display.

Display means for selectively displaying a plurality of types of indications attached to the connector base 15 is provided between the cover ring 18 and the circumferential surface of the connector base 15. That is, on the circumferential surfaces of the cover ring 18 and the spring body 22, which are elastically integrated and can be rotated around the connector base 15, there are windows 25 and 25 of the same shape that pass through the plate surface and overlap each other. 26 is formed. The windows 25 and 26 are formed in such a shape that one type of display, that is, one of the numbers, of the display label 20 attached to the connector base 15 can be displayed through the windows. The spring body 22 may be fitted into the cover ring 18 in advance, and the windows 25 and 26 may be formed therethrough. Alternatively, the uneven portion 2 of the connector base 15 may be formed on the inner peripheral surface of the cover ring 18.
4, a protrusion that elastically engages with the uneven portion 24 is formed to form a spring body 22.
It is also possible to realize a configuration in which the above is omitted.

An annular stopper ring 27 with an enlarged outer diameter of the circular edge on one end side is provided, and this stopper ring 27 is attached to the inner circumferential surface of the connector base 15 with the cover ring 18 and the spring body 22 attached. It is press-fitted against the

In this state, the cover ring 18 and the spring body 22 are rotatably attached to the outer periphery of the connector base 15, and the stopper ring 27 allows
These are held against the connector base 15 without slipping out of the connector base 15.

By placing a finger on the unevenness 19 of the cover ring 18 and rotating the cover ring 18, the cover ring 18 is elastically integrated with the spring body 22, rotates around the connector base 15, and passes through the windows 25 and 26. One of the numbers on the display label 20 at a position corresponding to the rotational position of the cover ring 18 is displayed on the outside. Select the number corresponding to the desired display in window 25.
When the rotation of the cover ring 18 is stopped at the rotation position indicated through
Since the cover ring 18 is elastically engaged with the concave portion of the connector base 15, the cover ring 18 is stably maintained at that position without moving relative to the connector base 15, and the display through the window 25 is stably set.

When connecting the cord C to the connector, the cord C is inserted into the connector base 15 from the stopper ring 27 side, and the core wire of the cord is electrically connected to the connection piece 17 at the insertion side end of the cord C. connected to. After connection, a cylindrical transparent cover 30 made of, for example, synthetic resin is disposed so as to cover the notch 16 of the connector base 15, and is secured to the connector base 15 with screws 31. Fixed. Since the connection state of the cord C within the connector base 15 can be monitored through the transparent cover 30, it is possible to check for disconnection.

As shown in Figure 3, for both ends of code C,
The connector 10 of this invention is connected, and the cover ring 18 is rotated on both ends thereof to set the same display, or in the embodiment, the same number, and this display is displayed externally through the window 25. put. On the other hand, there is a one-to-one correspondence in advance between the display to be set, the electrical device to be connected, and its connection end, and the number displayed externally through this window 25 indicates that the code C should be connected. It is associated with an electrical device and its predetermined connection end. Therefore, the electrical device and its connecting end to which the cord C is to be connected can be identified by the numbers displayed through the window 25 of this connector 10. For example, in a large studio where a large number of cords exist, such as when connecting synthesized sounds from a synthesizer or each performance sound to a mixer using multiple cords to enhance the acoustic effect, this invention can be used. By using connectors, it is possible to connect them to a predetermined connection end of a corresponding electrical device without erroneously connecting them. In addition, since the numbers displayed on the connector are associated with the electrical devices to be connected and their connection ends, even non-electrical engineers can easily connect multiple electrical devices according to the instructions of the general manager. Connection is possible, and the work required to connect electrical devices in advance is greatly reduced.

In the example, we have explained an example in which this invention is applied to a so-called plug-type connector to which a single-core cord is connected, but it is also applicable to a plug-type connector that connects a multi-core cord and has multiple connection pins, and other plug-type connectors. This invention can be applied not only to connectors of various types but also to connectors of various types.

Furthermore, in the embodiments, a configuration in which the displays are arranged in a line along the circumferential surface of the connector base has been described. It is also possible to adopt a configuration that allows a larger number of displays. In this case, the type of display for each column is, for example, characters or symbols, the first column is a major classification such as the type of device to be connected, and the second column is a minor classification such as the connection point of the device. Can be associated.

Furthermore, by selecting multiple rows of displays attached to the circumferential surface of the connector base and forming windows on the rotatable cover ring at shifted positions for each row, a unique display combination can be created for the connector. It is also possible to adopt a structure in which only one connector can be selected to avoid incorrect selection among a large number of connectors. In addition, the cover ring has a structure that can be slid and fixed at multiple positions in the axial direction of the connector base, and the display arranged in multiple rows on the circumferential surface of the connector base can be moved in the axial direction of the cover ring and around the axis. It is also possible to realize a system that can be selected by two operations, namely, the rotation of the .

As shown in the examples, the display means is not limited to the method of reading the display attached to the circumferential surface of the connector base through a window provided in the cover ring. For example, a second display is attached near the cover ring. It is also possible to realize a structure in which the torus is rotatably mounted, the second display can be set by this rotation, and the second display and the display of the connector base through the window are selected. . Alternatively, the final display can be set by a combination of color classification of code C and display selection by rotating the covering ring.

In this way, according to the connector of this invention, it is possible to easily set the display corresponding to the connector and maintain the display stably.For example, by attaching the connector of this invention to both ends of the cord. Therefore, the display unique to the code can be stably set and maintained using this connector. Therefore, by connecting and using this connector, a large number of intertwined cords can be identified and the connection work can be performed without error. For example, you can use an orchestra and a synthesizer to perform together in a studio, and use a mixer to mix creative sounds synthesized by the synthesizer or natural sounds with the sounds of the orchestra to create a unique effect, or create a 4-channel sound field to create a special sound field. When the number of electrical devices that need to be connected to each other increases, such as when realizing acoustic effects, and the cord connections between these devices become complicated, it is necessary to indicate the connectors and the connected points in advance. If you make it compatible, you won't make mistakes when connecting the cords.

In addition, by setting the correspondence between the cord display and the connection end of the electrical device in advance, even non-electrical engineers can make the connections without making mistakes based on the instructions of the person in charge of the project. Preparation time is significantly reduced.

As described in detail above, the connector of this invention allows various unique displays to be selected and displayed externally in a stable manner through simple operations.
For this reason, for example, by attaching the connector of this invention to both ends of the same cord and setting the same indication unique to that cord, this can be applied to the electrical device to which the cord is connected and its connection end. By associating setting displays, it is possible to avoid making mistakes when connecting cords to electrical devices, and it is possible to quickly perform work without making erroneous connections, such as when a large number of cords are connected in a complicated manner.
