Abstract
The utility model relates to an audio-video signal plug, comprising a needle core, a plug main body, a rubber core and a housing. The key point is that a hollow tubular shielding housing is provided between the plug main body and the signal line; one end of the shielding housing is connected with the back end of the plug main body and the other end is connected with the evaginating shielding layer of the signal line; the signal line is connected with the needle core of the plug main body after passing through the tubular shielding housing. Since the shielding housing is a total-enclosed structure, the shielding effect of the signal is improved greatly. Meanwhile, the utility model adopts the comb-shaped elastic ring and cancels the axial direction slot at the front end of the common audio-video signal plug main body so that the connecting and inserting are more convenient and the contact is more compact; the shielding effect is better and the structure is more simple.
Description
Affiliated technical field
The utility model relates to a kind of jockey that is used for audio/video signal transmission.
Background technology
At present, along with the fast development of computer technology, audio ﹠ video equipment progressively turns to digitlization, superior, and is more and more higher to the quality requirement of signal transmission, particularly strict more to the electromagnetic screen effect of requirement.And present common audio-video signal plug such as Fig. 1 institute, it is a kind of unenclosed construction, the masked segment of its plug body and the screen of holding wire just weld together simply, basically not shielding, thereby cause electromagnetic leakage, also be vulnerable to the interference of external signal, cause the audio-video signal distortion of transmission, reduced the quality of the audio-video signal that is transmitted.In addition, the body front end of the common audio-video signal plug part that is connected with corresponding socket adopts form axially grooved and that close up to produce elasticity, when making plug insertion socket, clamps the outer wall of socket.Because the plug body front end has axially grooved, cause shielding properties poor, plug makes the plug body front end behind the fluting follow the string easily continually, cause plug, socket loose contact, reduced shield effectiveness, and the main body of common audio-video signal plug is regulated the size of plug power owing to close up by fluting, complex structure and be not easy to machining control, and manufacturing procedure is also more.
Summary of the invention
In order to overcome above deficiency, the purpose of this utility model is, provides a kind of shield effectiveness good, patches the audio-video signal plug of fastening, easy to process full-closed structure.
The technical scheme that its technical problem that solves the utility model adopts is, the audio-video signal plug is by plug, by nook closing member, plug body, glue core and shell are formed, and closing branch strong is that a hollow tubular shielding case is arranged between plug body and the holding wire, and shielding case one end is connected with the plug body rear end, the other end is connected with the screen that holding wire turns up, and holding wire passes the tubular shielding shell and is connected with the nook closing member of plug body; Opening for fear of the plug body front end causes interference signal, guarantee that again plug body has enough plug power when inserting socket, the plug body front end patches in the cavity at position and is provided with a pectination elastic ring, and the outer of pectination elastic ring and the inwall of cavity fit tightly together; In order to guarantee that shielding case better is connected with the holding wire screen, also has a tubular shape conductor in the shielding case, tubular shape conductor is enclosed within on the holding wire, is connected with the screen that holding wire turns up, and the tubular shape conductor end that is connected with the screen that holding wire turns up is connected with screen; There is a cannelure junction of plug body rear end and shielding case, and the shielding case outside combines both by getting ready in the cannelure that is riveted on the plug body rear end securely
The beneficial effects of the utility model are, because shielding case has formed full-enclosed structure, the shield effectiveness of signal are improved widely.Adopt the pectination elastic ring, cancelled the axially grooved of common audio-video signal plug body front end, patch more conveniently thereby make, contact closelyr, shield effectiveness is better, and structure is simpler, and operation is less relatively, and processing is easy to control.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of the audio-video signal plug of prior art;
Fig. 2 is the assembling schematic diagram of the utility model audio-video signal plug;
Fig. 3 is the three-dimensional cutaway view of the utility model audio-video signal plug;
Fig. 4 is the connection diagram of the utility model plug body and shielding case.
Embodiment
Fig. 2, the utility model audio-video signal plug shown in Figure 3 are made up of nook closing member (1), plug body (2), glue core (3), tubular shape conductor (4), pectination elastic ring (5), shielding case (6) and shell (7), pectination elastic ring (5) is contained in plug body (2) front end and patches in the cavity at position, the outer of pectination elastic ring (5) and the inwall of cavity fit tightly together, behind plug insertion socket, the position of pectination elastic ring (5) the intermediate projections strain that is squeezed, to clamp the outer wall of socket, make the whole position that patches form a shielding construction.Tubular shape conductor (4) is enclosed within on the holding wire, be connected with the screen that holding wire turns up, shielding case (6) one ends are connected with the plug body rear end, there is cannelure (8) junction, the other end is connected on the tubular shape conductor (4), and the connecting portion bulk shielding of holding wire and plug audio frequency and video plug body (2) is got up.When assembling, shielding case adopts riveted joint with being connected of plug body, when shielding case (6) and plug body (2) afterbody excessively are coupled to the relevant position, by getting ready in the cannelure (8) that is riveted on plug body (2) rear end, both are combined securely in the shielding case outside.Behind trimming, wire stripping, the screen of holding wire is not to twist with the fingers into one as common way, but overturn after the integral body on the outer wall that is placed on holding wire, on that part of screen that turns over after again tubular shape conductor (4) excessively being coupled to, holding wire screen and tubular shape conductor (4) are combined as a whole, and an end of shielding case (6) then links together by the mode and the tubulose body (4) of riveting.
Claims (4)
1, a kind of audio-video signal plug, by nook closing member, plug body, glue core and shell are formed, it is characterized in that a hollow tubular shielding case is arranged between plug body and the holding wire, shielding case one end is connected with the plug body rear end, and the other end is connected with the screen that holding wire turns up, and holding wire passes the tubular shielding shell and is connected with the nook closing member of plug body.
2, audio-video signal plug according to claim 1 is characterized in that the plug body front end patches in the cavity at position to be provided with a pectination elastic ring that the outer of pectination elastic ring and the inwall of cavity fit tightly together.
