According to above-mentioned unit connector, wherein, described heart yearn is provided with 21 bundles, the skin of described every bundle heart yearn also is provided with woven shield, by the outer field woven shield of heart yearn and the double layer screen effect of wrapping up the establishment screen of all heart yearns, improve the shielding properties of coaxial line, reduced the decay of signal.
Performances such as the double braid screen is more little according to angle of weave when adopting litzendraht wire, and count is big more, and the projection coverage rate is just big more, and shield effectiveness is good are more worked out, and have improved the woven shield shield effectiveness.
According to above-mentioned unit connector, wherein, described copper sheathing skin also is enclosed with copper foil tape, by copper foil tape copper sheathing and screen is encased, and leaks with control signal.
According to above-mentioned unit connector, wherein, described plastic fixtures is arranged on the woven shield the inside, when promptly blocking plastic fixtures screen is handled outside the working of plastics.
Beneficial effect of the present invention is as follows:
The present invention is mainly used in the communication cabinet, and its function is the transmission of communication signal; All has good shield effectiveness by kirsite shell and the interference that has a coaxial pair signal of double braid screen.The kirsite shell is sturdy and durable, and shield effectiveness is good; Coaxial line has the effect of double layer screen than the electronics line, relatively is fit to the use between those electronic equipments that shielding properties is had relatively high expectations.Simultaneously, for reducing signal attenuation, between insulating barrier and woven shield, be inserted in copper sheathing, when the card plastic fixtures, woven shield is handled the plastic fixtures outside, use the copper foil tape of 0.025 * 10 * 50mm that copper sheathing and woven shield are wrapped in together, leak with control signal, reach better; It is had adorn advantage more convenient, that shielding properties is better, cost is low and signal attenuation is littler.
Description of drawings
Describe the present invention in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a coaxial line structural representation of the present invention.
Fig. 3 is one embodiment of the invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the present invention.
Referring to Fig. 1, unit connector of the present invention comprises kirsite shell 10, plastic fixtures 40, film fixing metal shell 20 and has the coaxial line 30 of double braid screen.In the present embodiment, 10 meters of these coaxial line 30 total lengths have effectively suppressed the electromagnetic interference between the electronic equipment, and coaxial line 30 is compared with the electronics line, has the effect of double layer screen, relatively are fit to the use between those electronic equipments that shielding properties is had relatively high expectations.
What deserves to be mentioned is, referring to Fig. 2, described coaxial line 30 comprises plural number bundle heart yearn 35 and all heart yearn 35 outermost insulating barriers 31 of parcel, in the present embodiment, heart yearn is provided with 21 bundles, internal layer at insulating barrier 31 also is provided with the woven shield 34 that wraps up all heart yearns, also is with copper sheathing 33 between this woven shield 34 and the insulating barrier 31, reduces signal attenuation.Performances such as be surrounded by woven shield 36 outside every bundle heart yearn 35, woven shield 34,36 is more little according to angle of weave when litzendraht wire, and count is big more, and the projection coverage rate is just big more, and shield effectiveness is good more and weaving.By the kirsite shell 10 of connector and the coaxial line 30 of band double braid screen 34, can effectively suppress the electromagnetic interference of the signal generation that it transmitted in the present invention.(σ Cu=5.8 * 107 Ω/m) is 0.29 to zinc, and the relative permeability during f=150kHz is 1, and the absorption loss during f=150kHz is 28dB/m, adopts kirsite shell 10 promptly both sturdy and durable, has electromagnetic shielding action again with respect to the conductivity of copper.
Among the present invention, described coaxial line 30 is fixed on the shell by plastic fixtures 40, and this plastic fixtures 40 is arranged on woven shield 34 the insides, promptly when card plastic fixtures 40 woven shield 34 is handled plastic fixtures 40 outsides; Use this connector can effectively suppress the input that electromagnetic interference between the electronic equipment does not influence signal again.
