Fig. 2 is the structural representation of the utility model cable shield device;
Fig. 3 is the structural representation of the equipment that is used in combination of screening arrangement of the present utility model.
Embodiment
See also Fig. 2, it is the structural representation of the utility model cable shield device.It comprises the carriage 1 that is hollow form, refer to reed 2 and in order to tighten refer to reed 2 tighten parts 5, wherein, described carriage 1 is connected on the equipment, refers to that reed 2 is connected on the carriage 1, refers to that reed 2, carriage 1 form a ducted body that passes in order to cable.
Carriage 1 is fixed on the incoming line or line outlet of equipment, after cable passes the ducted body of being made up of carriage 1 and finger reed 2, carries out colligation with tightening parts 5 from the outside that refers to reed 2 again, reaches the effect of carrying out shielding processing to those cables with this.Have the characteristics of toughness owing to refer to reed 2, make the cable-through hole size of cable in certain scope, change, can adapt to thus access device incoming line/line outlet number of cables what variation and the variation of cable footpath thickness, and by referring to that reed 2 reaches the effect of shielding electromagnetism.And the utility model limits the turnover number of cables by the size of the hollow shape of carriage 1.When the quantity of cable very for a long time, some less incoming lines or line outlet can be set on equipment so that the number of cables that makes turnover the utility model cable shield device is at a limited field, and then improve electromagnetic interference between the device inner cable.
Carriage 1 is fixed on the incoming line or the line outlet of equipment.A kind of execution mode that the utility model adopts is at the flange face of carriage 1 and the incoming line or the line outlet periphery of equipment some corresponding installing holes to be set respectively, carriage 1 is fixedlyed connected with equipment by the spiral shell select, so that the wire hole of carriage 1 is positioned at the incoming line or the line outlet of equipment just.The utility model can also adopt other syndetons to make carriage 1 be fixedly connected on the equipment, and the incoming line or the line outlet that make 1 wire hole of carriage 1 be positioned at equipment just get final product.
In addition, carriage 1 can be column, as cylindric.
Some installing holes that refer to reed 2 in order to connection are set in the side of carriage 1.Refer to that reed 2 will refer to that by rivet or screw reed 2 is installed on the described carriage 1.Refer to that reed 2 is not only to be confined to this with being connected of carriage 1.
The utility model can also comprise mask tape 4, is wrapped on the cable 3 in the described finger reed 2, improves the shield effectiveness that refers to the cable 3 in the reed 2 with this.In order to improve the efficient of shielding, the utility model can also adopt shielding strip to be wrapped on each cable that refers in the reed.Mask tape, shielding strip can adopt shielding adhesive tape or other can satisfy the bar of shielding requirements.
After the wire hole of cable 3 slave units passes; pass by carriage 1 again, refer to the ducted body that reed 2 is formed; then those cables 3 are twined in mask tape 4, carry out colligation with tightening parts 5 (as band) from the outside that refers to reed 2 at last, to reach the effect of shielding electromagnetism, protection cable 3.
More and shield effectiveness required when very high when the quantity of the cable 3 that passes wire hole, earlier cable 3 is passed by carriage 1, refers to the ducted body that reed 2 is formed, twine each cable 3 successively with shielding strip respectively then, carry out colligation with tightening parts 5 from the outside that refers to reed 2 at last, reach electromagnetic interference between the cable with this.
When the quantity of the cable 3 that passes wire hole more for a long time, can also be arranged on some incoming line/line outlets are set on the equipment, and at outer setting one cable shield device of the present utility model of each incoming line/line outlet 1.
See also Fig. 3, the structural representation of the equipment that it is used in combination for screening arrangement a kind of and of the present utility model, some incoming line/line outlets 21 are set on the described equipment, each incoming line/line outlet 21 is outer can equipment one screening arrangement 22, so that corresponding, and then reach the effect that the cable that passes in and out incoming line/line outlet 21 is shielded with the hollow aperture of screening arrangement.
The integrated level of equipment improves day by day, and the number of the cable of access device is more and more, also can satisfy the requirement that the number of cable of access device increases by above-mentioned structure.Simultaneously, because each cable shield device all is an independently shielding construction, so the shield effectiveness of all cables of equipment can not descend to some extent.
More than disclosed only be several specific embodiment of the present utility model, but the utility model is not limited thereto, any those skilled in the art can think variation all should drop in the protection range of the present utility model.
