Abstract
The utility model relates to an AV concentric audio/video frequency input output socket with sealing performance, comprising a AV concentric audio/video frequency input output socket body; in order to solve the problem of air leakage when using each of the AV concentric audio/video frequency input output sockets in prior art, the part of an opening on the back part of the AV concentric audio/video frequency input output socket is provided with an L-shaped cover plate matched with both the size and the form of the back part. After the adoption of the above structure, the inner part and the external part of a sound box are divided by the cover plate; so, the cases of air leakage resulted by the AV concentric audio/video frequency input/output socket are reduced to a great extent, and the acoustic fidelity of the voice output is improved.
Description
Technical field
The utility model relates to a kind of audio frequency and video input and output socket, and particularly a kind of AV is with core audio frequency and video input and output socket.
Background technology
The AV that produces on the existing market is with core audio frequency and video input and output socket, and structure is comparatively simple, and price is low, has been subjected to the welcome of audio ﹠ video equipment manufacturing enterprise.But along with the raising of people's living standard, people are also more and more higher to the requirement of quality of life.Existing AV when it uses on audio amplifier, can produce gas leakage with ventilation before and after the core audio frequency and video input and output socket, so influenced the tonequality of audio amplifier output greatly, has influenced audio ﹠ video equipment and has moved towards high-end market.
Summary of the invention
In order to overcome above-mentioned defective, the utility model purpose is to provide a kind of and allows audio amplifier manufacturer not revise any parts just to improve the AV with sealing property of voice output tonequality with core audio frequency and video input and output socket.
For achieving the above object, the AV that the utlity model has sealing property is with core audio frequency and video input and output socket, comprise AV with core audio frequency and video input and output jack body, partly be provided with the L shape cover plate suitable with core audio frequency and video input and output jack body open back with the back size shape at described AV.
After adopting said structure, cover plate then is spaced from each other the inside and the outside of audio amplifier, like this, can reduce the gas leakage situation of AV with the reason generation of core audio frequency and video input and output socket to a great extent, has improved the tonequality of voice output.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Fig. 1 will install the schematic diagram of closing cap for audio frequency and video input and output socket.
Fig. 2 looks schematic diagram for the master of cover plate shown in Figure 1.
Fig. 3 is the A-A schematic diagram of cover plate shown in Figure 2.
Fig. 4 is the B-B schematic diagram of cover plate shown in Figure 2
Embodiment
Extremely shown in Figure 4 referring to Fig. 1, the AV that the utlity model has sealing property is with core audio frequency and video input and output socket, comprise AV with core audio frequency and video input and output jack body 2, partly be provided with the L shape cover plate 1 suitable with core audio frequency and video input and output jack body 2 open back with the back size shape at described AV.Described cover plate 1 can be installed in AV with core audio frequency and video input and output jack body 2 backs by modes such as grafting, joggle, bonding or welding.For example attach it in the socket main body 2, weld with ultrasonic welding machine, because hyperacoustic dither, with the plastics instant melting, seal cover board 1 and socket main body 2 are combined, and cover plate 1 then separates the inside and the outside of audio amplifier, like this, can reduce the gas leakage situation of AV to a great extent, improve the tonequality of voice output with the reason generation of core audio frequency and video input and output socket.
As further improvement of the utility model, described cover plate is that hermetic seal cooperates with AV with core audio frequency and video input and output jack body 2 backs.Technology such as for example bonding or ultrasonic bonding realize hermetic seal.Like this, can stop the gas leakage situation with the reason generation of core audio frequency and video input and output socket, further improve the tonequality of voice output owing to AV.
For the ease of making, installing, and make the socket outward appearance seem comparatively attractive in appearance, be provided with depression 3 at described AV with core audio frequency and video input and output jack body 2 back surfaces and shell inner surface joint, the exterior contour of described cover plate 1 and described depression 3 are suitable.Like this, can cover plate be fixed on AV with core audio frequency and video input and output jack body 2 backs, realize hermetic seal by technology such as bonding or ultrasonic bonding.The section of described depression 3 can be rectangle, trapezoidal or triangle, and described cover plate 1 edge then should be suitable with it rectangle or trapezoidal.
For the ease of welding, strengthen weld strength, reduce manufacturing cost, on the described cover plate 1 inboard edge consistent, be provided with installation direction with AV with the suitable pointed protruding sealing wire 4 of triangle of core audio frequency and video input and output socket 2 binding sites.Like this, when welding with ultrasonic welding machine, because hyperacoustic dither, but make the plastics instant melting of the pointed high spot of triangle on the cover plate, moment combines between cover plate and the jack body, and reaches hermetic seal.Certainly, consider that from technological angle the pointed projection of above-mentioned triangle also can be trapezoidal pointed projection.
In order to strengthen the intensity of cover plate, described AV with core audio frequency and video input and output socket in the appropriate location be provided with the cover plate support column of hollow, the relevant position on described cover plate 1 then is provided with the plug tenon 5 suitable with hollow space.
AV described in the utility model is that four AV are with core audio frequency and video input and output socket with core audio frequency and video input and output socket.
