Description

Video signal sound equipment signal line jockey

The utility model relates to the signal transmission, is specifically related to a kind of jockey of signal line.

General television set, Video Recorder, video disc player, sound equipment, loudspeaker, enlarger etc., the output or the input of signals such as its image, sound, be mostly by signal jockey set on the body and peg graft thereon corresponding signal line and reach.And generally formed by socket and plug in order to the jockey system of connecting circuit with transmission video signal or sound equipment signal, this socket is general alleged AV terminal, it is to be installed on the circuit board of electrical equipment, plug then is installed on the two ends of signal line, therefore, be able to be plugged on the socket of electrical equipment, connecting two electrical equipment, and transmit electric signals such as image or sound by signal line by the plug of signal line.The concrete structure of known signal connector as shown in Figure 4, the top that this socket a lies in a column cap a1 is provided with a jack a2, and be provided with insulator between this column cap a1 and jack a2, column cap a1 and jack a2 then distinctly are connected on the circuit board, again this plug b lie in an outer sleeve b1 in be provided with inserting column b2 in the heart, and also be provided with insulator between this outer sleeve b1 and interior inserting column b2, and make outer sleeve b1 and interior inserting column b2 connect signal line separately.The signal line jockey of structure like this, the outer sleeve b1 of plug b is enclosed within outside the column cap a1 of socket a, and the interior inserting column b2 of plug b is inserted the jack a2 of socket a, makes plug b be able to plug-in mounting and is connected on the socket a, thereby signal line must be inserted and be connected on the socket of electrical equipment.The weak point of this signal line jockey is, because its socket a has installed when dispatching from the factory and has been fixed on the electrical equipment, yet the selected electrical equipment such as video signal sound equipment of consumer are not all to come from same manufactory, again, signal line except electric equipment products are appended give, the consumer may choose in addition because of signal line falls short of, therefore, the socket a and the plug b of all signal jockeys are all different vendor's manufacturing, and because keep away the problem of unavoidable manufacturing tolerance on making, as, if the socket a of the minimal tolerance of first company production (being minimum outer diameter) still greater than the plug b (being maximum inner diameter) of the maximum allowance that company B produced, then can't be inserted into plug b on the socket a; Otherwise, if the socket (being maximum outside diameter) of the maximum allowance that first company is produced then can't firmly be inserted into plug b on the socket a again much smaller than the minimal tolerance (being minimum outer diameter) that company B produced.Though the manufacturing tolerance standard of regulation is arranged, but still can't avoid the generation of above-mentioned situation, and because of the internal diameter of the outer sleeve b1 of plug b is a fixed dimension, use one to have wearing and tearing for a long time unavoidably, therefore cause the situation of loose contact easily and influence sound and the image people transmits.For improving the plug b disappearance in the use of above-mentioned known signal line, and as shown in Figure 5 another kind of known configuration is arranged, its outer sleeve b1 that lies in plug b goes up ring-type and offers several narrow fluting b11, so that the outer sleeve b1 of plug b has the elasticity of contraction, but its elastic bunch is leaned against on the column cap a1 of socket a.Yet this kind offered narrow fluting b11 and made its rubber-like practice on the outer sleeve b1 of plug b, when pulling up plug b, if skew is outwards arranged slightly, then make the opening of outer sleeve b1 produce distortion easily, and outer sleeve b1 closely is enclosed within on the column cap a1 of socket a, make between plug b and the socket a and have loosening phenomenon, and the situation that has a loose contact takes place.

The purpose of this utility model provides a kind of video signal sound equipment signal line jockey of architecture advances, makes the plug that is connected the signal line end can guarantee closely to be socketed in the gang socket.

Realize the utility model of above-mentioned purpose, similarly to prior art mainly be made of a socket and plug that wherein this socket top of lying in a column cap is provided with a jack, and is provided with insulator between this column cap and jack, column cap and jack distinctly are connected on the circuit board; This plug lie in an outer sleeve in be provided with inserting column in the heart, and this outer sleeve and interpolation intercolumniation also are provided with insulator, outer sleeve and interior inserting column connect signal line separately, characteristics of the present utility model are, the outer sleeve internal diameter of plug is slightly larger than the external diameter of column cap, and an elastic ring is housed in outer sleeve, and this elastic ring is one to have the ring of opening, is provided with the top flat of convex in its periphery.So the plug of structure when being socketed in it on the socket, becomes by the elastic ring gland on the column cap outer peripheral face of plug, makes plug and socket have syndeton closely.

Advantage of the present utility model is, because the utility model is equipped with an elastic ring in the outer sleeve of plug, makes to be tight by this elastic ring between plug and socket and to be connected, and can avoid influencing because of loose contact the transmission of sound and image.And this elastic ring makes plug increase the grafting scope, makes it to overlap on the column cap of the socket that is inserted in different size (close scope).

Embodiment of the present utility model as shown in drawings.Below in conjunction with drawings and Examples the utility model is further described.

At first see also Fig. 1, Fig. 2.See by figure, the signal line jockey of present embodiment mainly is made of a socket 1 and a plug 2, and wherein, the top that this socket lies in a column cap 11 is provided with a

jack

12, and 12 of this column cap 11 and jacks are provided with insulator, and column cap 11 and jack 12 distinctly are connected on the circuit board; Plug 2 in the present embodiment, lie in an outer sleeve 21 in be provided with inserting column 22 in the heart, and this outer sleeve 21 and interior 22 of inserting columns also are provided with insulator, outer sleeve 21 and interior inserting column 22 connect signal line separately, in the present embodiment outside the plug 2 internal diameter of sleeve 21 be slightly larger than the external diameter of the column cap 11 of socket 1, and an elastic ring 3 is housed in outer sleeve 21, and this elastic ring 3 is one to have the ring of opening 31, is provided with the top flat 32 of convex in its periphery.As shown in Figure 3, when on column cap 11 outer peripheral faces that plug 2 are enclosed within socket 1 with its outer sleeve 21, when the interior inserting column of plug 2 22 inserts in the jack 12 of sockets 1,2 of plugs by elastic ring 3 elasticity glands on the column cap 11 of plug 1, particularly the top flat 32 of elastic ring 3 convexes flexibly is resisted against on the circumference of column cap 11, then makes the column cap 11 of socket 1 contact conducting with the outer sleeve 21 of plug 2 by elastic ring 3.

Also structure is seen from the above mentioned, because sleeve 21 is to be enclosed within on the column cap 11 of socket 1 by elastic ring 3 outside this plug 2, therefore, if when the tolerance on making is excessive, this elastic ring 3 still can closely be resisted against on the column cap 1 of socket 1, and must exempt the situation generation of loose contact.And the elasticity of this elastic ring makes the utility model plug produce the bigger scope that patches, and promptly makes same plug 2 can be inserted on the socket 1 of different vendor's production, has preferable ease of use.

Again because this elastic ring 3 is to be enclosed within the outer sleeve 21 of plug 2, so, when when pulling out title plug 2, this outer sleeve 21 can't be out of shape, and because this elastic ring 3 has an opening 31, its elasticity with circumference is expanded outwardly, thus can not produce the situation of loose contact because of distortion, to avoid influencing the transmission of sound and image.
