In the general machine room, digital video coding and decoding equipment is to be contained in the rack mostly, and some shootings, image processing and modulating equipment then are that local the placement arranged in addition.In order to connect two audio frequency apparatuses, prior art generally adopts two sections cable buttings, and promptly an end of every section cable is connected with connected equipment respectively, and its syndeton can be determined according to the type of apparatus output signal connector; The free end of two sections cables then docks by blocking agricultural hair style connector mostly.Block agricultural hair style connector and constitute, as shown in Figure 1 by a card farming male 01 that can cooperatively interact and a card farming female 02.Because installations and facilities are many in the machine room, the space is little, then the stube cable line is many and close, and the problem of bringing like this has:
1, cabling is very in disorder, and is not attractive in appearance.The machine room center line is original just many, after two voice-frequency cables connect by card farming head, generally uses cableties and directly ties up in the frame both sides.If the frame both sides do not have corresponding tier, then directly lowering is gone down, and is very at random, also dangerous.
2, be difficult to confirm the sign of every line, bad location when problem.Because general every cable all is a standard component, its sign is unified basically, therefore is difficult to the interface of determining that every line is connected.
Technology contents
The purpose of this utility model is to propose a kind of switching device, and cable routing in the prior art is in disorder to solve, the technical problem of the inconvenient identification of cable routing.
For addressing the above problem, the utility model provides following technical scheme:
A kind of switching device wherein, comprises the frame that is provided with front panel, and the rear end of this frame laterally is provided with socket mouth card farming connector backwards at least, this block the flanging of agricultural connector top corresponding each block agricultural connector and be provided with the cable identification sequence number.
In the utility model one preferred embodiment, described frame is leading portion thickness height, step setting that back segment thickness is low, the thickness of its leading portion is no more than the height of described front panel, the upper surface of back segment is lower than the hole of being located at the agricultural connector rear end face of described card wire bushing, the leading portion of described plate face also is provided with groove, described frame front panel both sides are provided with mount angle, and the back segment of described frame can have through hole.
The plate upper surface of described groove laterally is provided with the protruding bridge of a plurality of wirings, also is provided with the protruding bridge of wiring on the flanging after the cable identification sequence number of described card farming connector top.
The agricultural connector of described card is a card farming female plug seat, and it can be 14 at most.
The agricultural connector of described card is a card farming male plug, and it can be 16 at most.
The utility model is lined up a card farming female plug seat or a card farming male plug set of one of strain relief clamp farming head connector, and at the good cable identification serial number of the agricultural connector subscript of card, this device has the following advantages:
1, the cabling of rack back is uniform, and safety is attractive in appearance;
2, easy for installation, after the cable that is gone out from the coding and decoding device is assemblied on this switching device, can dispose on-the-spot required cable as required, directly plug butt joint cable is easy to use.
When 3, problem being arranged, the cable location is more straightforward, can find the corresponding port by sequence number.Especially obvious when number of cables is very big, operating efficiency greatly improves.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described, wherein:
Fig. 1 is the stereogram of a pair of male and female joint of the existing agricultural head connector of card;
Fig. 2 is the front perspective view of the utility model card farming connector when being the female plug seat;
Fig. 3 is the rear perspective view of the utility model card farming connector when being the female plug seat;
Fig. 4 is the rear perspective view of the utility model card farming connector when being male plug.
Embodiment
Fig. 2, shown in Figure 3 is a preferred embodiment of the present utility model.A kind of switching device of voice-frequency cable comprises the frame 2 that is provided with front panel 1, and the rear end of this frame laterally is provided with a socket mouth card farming female plug seat 4 backwards, according to the difference of transit cable quantity, and row's number of the agricultural connector 4 of card that can superpose.This block the flanging of agricultural connector top corresponding each block agricultural connector and be provided with cable identification sequence number 5.In order to increase the rigidity of this device, described frame 2 is leading portion thickness height, step setting that back segment thickness is low, the thickness of its leading portion is no more than the height of described front panel 1, the upper surface of back segment is lower than the hole of being located at the agricultural connector 4 rear end face wire bushings 10 of described card, the leading portion of described plate face also is provided with two square grooves 6, the shape of this groove and quantity can be provided with flexibly, described frame front panel 2 both sides are provided with mount angle 11, can be used for being connected of this device and audio frequency apparatus frame.The back segment of described frame 2 has two square through holes 8, and the shape of this through hole and quantity can be provided with flexibly.The plate upper surface of described groove 6 laterally is provided with the protruding bridge 9 of a plurality of wirings, also is provided with the protruding bridge 9 of wiring on the flanging after the agricultural connector of the described card top cable identification sequence number 5.A described card farming female plug seat 4 can be 14 at most, and its concrete quantity can be selected according to transit cable quantity.
