In order more to be expressly understood above-mentioned purpose, the feature and advantage of the utility model, the utility model is further described in detail below in conjunction with accompanying drawing and embodiment.
A lot of details have been set forth in the following description so that make much of the utility model; But; The utility model can also adopt other to be different from other modes described here and implement, and therefore, the utility model is not limited to the restriction of following disclosed specific embodiment.
Embodiment one:
Fig. 1 to Fig. 3 shows the structural representation of the said audio frequency and video patchcord of the utility model.Wherein, Fig. 1 is that master according to said audio frequency and video patchcord one embodiment of the utility model looks sketch map; Fig. 2 is that sketch map is looked on the left side of structure shown in Figure 1; Fig. 3 is the schematic top plan view of structure shown in Figure 1.
Extremely shown in Figure 3 like Fig. 1; The utility model provides a kind of audio frequency and video patchcord 10, comprises many connecting lines 1, and an end of every said connecting line 1 is connected with an audio frequency and video plug 2 respectively; The other end is integrated into a splicing ear 3; Said audio frequency and video plug 2 comprises signal host node 21 and ground wire node 22, and each said signal host node 21 is corresponding to a stitch 7 (certainly, splicing ear also can be that pin is formed) of said splicing ear 3; The combination of each said ground wire node 22 or a plurality of said ground wire nodes 22 is corresponding to a stitch 7 (certainly, splicing ear also can be that pin is formed) of said splicing ear 3.
Like this, an end of connecting line 1 is provided with independently audio frequency and video plug 2, the other end is integrated into a splicing ear 3; Greatly facilitate being connected of television set and test instrumentation; Improve the testing efficiency of television set audio frequency and video sockets significantly, improved the speed of production of television set complete machine, reduced labour intensity.
Preferably; What the described audio frequency and video patchcord 10 of present embodiment was directed against is the television set that two groups of AV sockets and a group component audio frequency and video socket (being the high-definition signal socket) are arranged; To with the television set of this model; We provide a kind of audio frequency and video patchcord 10; Wherein said connecting line 1 comprises a group component audio-video signal line and two groups of AV holding wires, and wherein every group of said component audio-video signal line comprises two-way audio holding wire and three road video signal cables, and every group of said AV holding wire comprises one road video signal cable and two-way audio holding wire.
One end of every holding wire all has an audio frequency and video joint, and this audio frequency and video joint can be connected on the audio frequency and video socket on the television set accordingly, tests.
For the ease of the streamline staff each connecting line is made a distinction; Preferably, the said two-way audio holding wire in every group of said AV holding wire, the said component audio-video signal line, said three road video signal cables in the said component audio-video signal line connect into a wire harness through external member 4 respectively.
Describe for ease, each holding wire is numbered as follows: two groups of AV holding wires are divided into first group of AV holding wire and second group of AV holding wire, and component audio-video signal line is divided into component audio signal wire group and component video signal line group at present.Wherein first group of AV holding wire comprises the first left channel signals line 101, the first right-channel signals line 102 and first video signal cable 103; Second group of AV holding wire comprises the second left channel signals line 201, the second right-channel signals line 202 and second video signal cable 203; The component audio signal wire comprises the 3rd left channel signals line 301 and the 3rd right-channel signals line 302; The component video signal line comprises the 3rd video signal cable 401, the 4th video signal cable 402 and the 5th video signal cable 403.
Further, the said ground wire node 22 of the said audio frequency and video plug 2 in each said wire harness is with a stitch 7 that is connected to said splicing ear 3 (certainly, splicing ear also can be that pin is formed).
Can know with reference to above-mentioned grouping; Connecting line in first group of AV holding wire is formed a wire harness through first external member 41; Connecting line in said second group of AV holding wire is formed a wire harness through second external member 42; Said component audio signal wire is formed a wire harness through the 3rd external member 43, and said component video signal line is formed a wire harness through quadruplet spare 44, and this wire harness of being made up of external member 4 can the handled easily personnel be distinguished and respectively organized holding wire; Convenient audio frequency and video socket with audio frequency and video plug insertion television set is increased work efficiency.
Owing to the other end of connecting line is integrated into splicing ear, so the ground wire node of audio frequency and video plug need independently take the stitch 7 of splicing ear 3, in present embodiment; Connecting line 1 and audio frequency and video plug 2 comprise 11; And audio frequency and video plug 2 comprises signal host node and ground wire node, like this, just needs splicing ear 3 that 11 signal host node stitch and 11 ground wire node stitch are arranged; Need splicing ear 3 that at least 22 stitch are arranged altogether; This will make the size of splicing ear become big, and cost increases, and be unfavorable for and being connected of test instrumentation.
For this reason; The utility model provides a kind of scheme; The said ground wire node 22 of the audio frequency and video plug 2 of the connecting line in each wire harness is connected to simultaneously a stitch of said splicing ear 3; Can cause a stitch of splicing ear 3 like the ground wire node 22 of three audio frequency and video plugs in first group of AV holding wire; The ground wire node 22 of three audio frequency and video plugs in second group of AV holding wire can cause a stitch of splicing ear 3, and the ground wire node 22 of two audio frequency and video plugs in the component audio signal wire can cause a stitch of splicing ear 3.Like this, only need splicing ear 3 that 11 signal host node stitch and 4 ground wire node stitch are arranged, totally 15 stitch 7 can meet the demands, and have simplified the structure of splicing ear 3, have dwindled the size of splicing ear 3, have reduced cost effectively.
Preferably, all one-body molded on each said external member 4 have a projective structure 5.
Further, the shape of the projective structure 5 on each said external member has nothing in common with each other.
On said external member 4, projective structure 5 is set, and the shape of projective structure 5 is had nothing in common with each other, main purpose is for each wire harness is distinguished, and makes things convenient on the streamline operator to the quick identification of each wire harness.Such as; The patty that can the projective structure 5 on first external member 41 is set to protrude; The cross section that projective structure 5 on second external member 42 is set to protrude is trapezoidal cylinder; Projective structure 5 on said the 3rd external member 43 is set to triangular prism, the square that the projective structure on the quadruplet spare 44 5 is set to protrude.This structure can the handled easily personnel easily be distinguished each wire harness.
Certainly, can also on external member 4, form the Chinese character title of each wire harness, so that operating personnel directly carry out identification.
In addition, the color of the connecting line in each wire harness also can be distinguished, and to give operating personnel's identification more intuitively, is the sign that the color of each connecting line is carried out like table one:
Table one: the color assignment correspondence table of each connecting line
| Connecting line title and numbering | Color |
| The first left |
In vain |
| The first right- |
Red |
| First |
Yellow |
| The second left |
In vain |
| The second right- |
