Description

  The present invention relates to an improvement in a power strip, and more particularly to an audio power strip that can improve the sound quality of an audio device and can significantly reduce the adverse effects of other connected devices.

  As is well known, between audio fans, in order to operate multiple audio devices or related electrical products at the same time, the built-in outlet is not used directly, but the power supply is connected through a dedicated power strip in the middle. It is common.

  Also, audio fans are extremely eager to improve the sound quality emitted by audio equipment, and are always looking for ways to improve sound quality even with a single power connection.

  Conventionally, in order to meet the demand of such an audio fan, the power plug is prevented from wobbling by sandwiching a plate-like plug fixture between the power plug of the audio device and the outlet. There has been proposed a technique for eliminating the noise caused by (see, for example, Patent Document 1).

  By the way, noise contamination in the power supply is often caused not only by the wobbling of the power plug, but also due to vibrations of the wires and other connected devices that use inverters. There is some noise in the electricity.

  However, since the above prior art has no effect on such already mixed noise, in order to avoid the noise, there is no choice but to operate the audio equipment using an extremely expensive independent power source. It was very uneconomical.

  Moreover, in the general power strip as described in <Patent Document 2>, since the inside of the tap case was an integral hollow space, when connecting and using a plurality of audio devices and electrical products, An electromagnetic field was generated at the periphery of each outlet connected to the power plug, and these interfered with each other and interacted to generate new noise.

  In addition, since the conventional power strips have outlets connected in series, noise generated by other electrical devices connected to the power strips flows backward, adversely affecting audio devices connected to other outlets. As a result, the sound quality that audio equipment emits has not reached a level that audio fans can satisfy.

In addition, in the past, there was a power strip for the purpose of suppressing power noise as described above, but there was no one intended to give diversity to the sound quality of connected audio devices. I felt unsatisfactory.
Japanese Utility Model Publication No. 7-42011 (page 2-12, FIG. 1-5) JP 2002-93535 A (page 2-4, FIG. 1-7)

  The present invention has been made in view of the above-mentioned problems. The object of the present invention is to improve the sound quality of audio equipment and to go one step further and connect other electrical equipment. It is another object of the present invention to provide an audio power strip excellent in functionality that does not deteriorate the sound quality level of the audio device and can give a special texture to the tone emitted by the audio device.

  Means adopted by the present inventor for solving the above problems will be described with reference to the accompanying drawings.

In other words, the present invention is a power strip into which a plurality of power plugs P of audio equipment can be inserted,
A plurality of outlets 2, 2,. A power connector 3 that is arranged with the insertion surface 22 exposed to the outside, and that connects the outlets 2, 2... In parallel with a connection line 31 and can be connected to a power source via a power cord 32. While being configured to be mounted inside the case, inside the tap case 1, the outlets 2, 2... And the hollow portions 11, 11. Is formed by forming a detour 13 that spatially connects the sections 11, 11 and the power connector 3 and the outlets 2, 2,... Individually connected to the detour 13 through a connection line 31. There is.

  Further, in the present invention, in order to solve the above-described problem, in addition to the above-described means as necessary, a technical means of using an aluminum alloy having excellent shielding properties against high-frequency electromagnetic waves as the material of the tap case 1 is used. Can be adopted.

  In addition, in the present invention, in order to solve the above-described problems, technical means for producing the tap case 1 by cutting a metal lump can be employed in addition to the above-described means as necessary.

  In addition, in the present invention, in order to solve the above-described problem, in addition to the above-described means, if necessary, the peripheral edge of the insertion surface 22 of the outlet 2 in the tap case 1 can be fitted with the tip of the electric plug P. The technical means of forming the hole 15 shape can be employed.

  Further, in the present invention, in order to solve the above-mentioned problems, in addition to the above means, a noble metal excellent in conductivity and sterility is used as a metal plating material to be applied to the blade bracket 21 of the outlet 2 as necessary. The technical means of using can be adopted. .

  In addition, in the present invention, in order to solve the above-described problems, technical means for easily configuring the outlet 2 with respect to the tap case 1 in addition to the above-described means can be employed as necessary.

  In the present invention, the entire tap case is made of a material having excellent conductivity, and a hollow portion to which the power connector and the outlet are attached is separately formed inside the tap case, and these hollow portions are bypassed. By connecting the power connector and each outlet through the connection line to this detour, when power flows through the connection line running in the detour, electromagnetic waves disturbed in the high frequency range are reflected and absorbed by the peripheral wall of the detour Thus, the electromagnetic field generated around the connection line can be made constant, so that noise mixed in the power can be reduced before reaching the outlet. This makes it possible to obtain a clear sound quality with high satisfaction even when the audio device is operated using a power supply from a built-in outlet that contains a lot of noise.

  In addition, since the hollow part to which the outlet is attached is surrounded by the partition inside the tap case, the electromagnetic field generated around the outlet can be shielded in the hollow part, so that the electromagnetic fields generated around each outlet interfere with each other. There is nothing. Therefore, when a plurality of electrical devices are connected to the tap, it is possible to prevent the generation of new noise caused by that.

  In addition, by connecting the power connector and each outlet in parallel by the connection line, it is necessary to pass through the power connector once for the noise flowing backward from the specific electrical equipment to reach other connected equipment. As a result, the noise travel distance is significantly increased compared to the case of connecting them in series, so that the adverse effects of backflow noise can be significantly reduced. In addition, since the backflow noise can be further reduced by the detour, the adverse effect of the backflow noise can be remarkably reduced.

  Also, by metal plating the blade bracket of the outlet, it is possible to add subtle modulation to the current with the electric resistance of the plating, and the modulation gives a special texture corresponding to the plating material to the tone of the audio equipment. Because it becomes possible to enjoy, you can enjoy the music full of taste.

  Therefore, according to the present invention, the sound quality level of the connected audio device can be improved to a level that an audio fan can convince, and a power strip suitable for using audio that is not bothered by the influence of other connected electric devices can be provided. Since it can be provided, it can be said that the practical utility value of the present invention is very high.

Since it is possible to provide music, it is possible to enjoy music that is full of taste.

  In this embodiment, a metal lump of aluminum alloy was cut to produce a tap case having hollow portions 11, 11,. As a result, the tap case 1 can have a more rigid structure as compared with the assembly type, so that the vibration of the tap case 1 caused by an external influence can be suppressed. It is possible to greatly reduce noise generated by the fluctuation of the noise.

  In addition, since the peripheral surface of the insertion surface 22 of the outlet 2 in the tap case 1 is formed in the shape of a sinking hole 15 that can be fitted to the tip of the electric plug P, the plug P is wobbled when the power plug P is inserted. The resulting noise can also be prevented.

“Second Embodiment”
A second embodiment of the present invention will be described below with reference to FIGS. In this embodiment, the outlets 2, 2... Are arranged in two rows on the tap case 1, and the insertion surface 22 of the outlet 2 appears on both the upper surface and the side surface of the tap case 1 (see FIG. 5). ). This makes it possible to produce power strips that can be used in various usage situations.

  The tap case 1 is provided with hollow portions 11, 11,... Corresponding to the arrangement of the outlets 2, 2,. Further, the bypass 13 is formed so as not to face the entrance to the hollow portion 11 (see FIGS. 6 and 7).

  Moreover, in this embodiment, the copper alloy excellent in the shielding effect with respect to the electromagnetic wave of the zone | band lower than aluminum was used for the material of the tap case 1.

  Furthermore, in this embodiment, the outlets 2, 2... Are easily attached to and detached from the inside of the tap case 1 using screw materials, so that different types of metal plating are applied to the blade receptacle 21 of the attached outlet 2. Therefore, it is very convenient when selecting and changing metal plating.

  The present invention is generally configured as described above. However, the present invention is not limited to the illustrated embodiment, and various modifications can be made within the description of the “Practical model registration claims”. The plating material used for the blade bracket 21 of the outlet 2 may be any material other than those listed above as long as an effect on sound quality is recognized.

  If the material of the tap case 1 is also excellent in conductivity, it is not limited to an aluminum alloy or a copper alloy. Of course, the arrangement and number of outlets 2 can be changed according to the assumed usage situation. Both belong to the technical scope of the present invention.

  Recently, there are many enthusiastic audiophiles who are willing to buy very expensive audio equipment and connecting parts to enjoy higher quality music at home. And they have repeated various trials and errors to find a way to improve sound quality by combining these devices and parts. However, in the market, there is still no power strip that can be said to be effective for achieving a sound quality level that audio fans can satisfy.

  Under such circumstances, the audio power strip of the present invention minimizes the adverse effects of electromagnetic noise generated inside and outside of the power strip, and can also provide a special texture to the tone of the audio device to realize a delicious sound quality. Since it is a very effective technology, it can fully meet the demands of the above-mentioned audio fan, and thus it can be said that the industrial utility value of the present invention is very high.
