Specific implementation mode
The porous electromagnetic shielded cable connector of the utility model is described in more detail below in conjunction with schematic diagram,
In illustrate the preferred embodiment of the utility model, it should be appreciated that those skilled in the art can change described here practicality
It is novel, and still realize the advantageous effects of the utility model.Therefore, following description should be understood as people in the art
Member's is widely known, and is not intended as limitations of the present invention.
As shown in Figure 1 to Figure 2, the utility model proposes a kind of porous electromagnetic shielded cable connectors, including locknut
1, conductive seal 2 and fittings body 3 (as shown in Figure 1).Wherein, conductive seal 2 uses electric silica gel (conductive silicon rubber) material
Matter has good conductive property, leakproofness, resistant of high or low temperature and anti-flammability, can ensure that product is anti-within the scope of locking wire
Achieve the effect that electromagnetic compatibility while water tightness；Locknut 1 and fittings body 3 be all made of metal material (such as brass,
Steel) it is made, plating nickel on surface processing has good conductive property and anticorrosive property.
The front end 2a of conductive seal is cylindrical, and rear end 2b is with a narrow upper and lower width round table-like (as shown in Figure 1), described to connect
The leading inside face of head body 3 is equipped with the compatible cone mouth 7 (as shown in Figure 2) in rear end of conductive seal 2.After conductive seal
End 2b is axially sleeved ikn the cone mouth 7 of fittings body, and locknut 1 is screwed in the front end of fittings body 3 and is coated on conductive seal 2
In it (locknut 1 is screwed onto on the external screw thread of fittings body 3).Conductive seal 2 is axial to offer 4 (such as Fig. 2 of multiple cable holes
It is shown), for accessing more cables simultaneously, and electromagnetic shielding can be carried out at the same time to more cables.The porous electromagnetic shielding electricity
The overall structure of cable joint is simple, low manufacture cost and shield effectiveness are good, than the protection etc. of conventional porous electromagnetic compatibility plug connector
Grade higher.
