The detailed explanation will In the following description.

Please also refer to Figures 1 to 6 at the same time, which are the three-dimensional view of the preferred embodiment of the new invention to the cross-sectional view taken along line AA in Figure 5. It can be clearly seen from the figure when the above components are assembled. The mating shielding shell 21, the mating glue 22, and the mating terminal 221 are combined to form a female connector 2, and the plugging shielding shell 31, the mating glue 32, and the plug terminal 321 are combined to form a male connector.

While the female connector 2 and the male connector 3 are combined with each other, the plug shield shell 31 is located in the butt shield shell 21. As shown in the fourth to sixth figures, the plug shield shell 21 and the plug The components outside the shielding shell 31 are hidden to clearly show the main components of the present invention.

While the mating terminal 221 and the plug terminal 321 are electrically combined, electromagnetic waves, noise, etc. can be blocked from the mating shield shell 21 and the plug shield shell 31. Electromagnetic interference can cause signal transmission errors between the two electrical connectors, and even block the signal transmission. In more serious cases, it can cause accidents and cause injuries.

Electromagnetic interference is divided into conducted interference and radiated interference according to its coupling mode. Conducted interference refers to the energy of electromagnetic noise in the circuit in the form of voltage or current, passing through metal wires or other components (such as capacitors, inductors, transformers, etc.) Coupled to the interfered device (or circuit). Radiation interference refers to the electromagnetic noise energy in the form of electromagnetic field energy, which propagates through space radiation and is coupled to the interfered device (or circuit).

Regardless of the type of electromagnetic interference, it will affect the signal transmission. As shown in Figure 6, the cross section of the contact point between the butting terminal 221 and the plug terminal 321 is taken as a cross-section view.

When the signal is transmitted, the other unrelated electromagnetic wave signals are blocked from the outside to achieve the effect of 360-degree surround shielding.

In addition, through the structure in which the docking shell coupling portion 213 is correspondingly coupled to the docking glue coupling portion 222, and the plug shell coupling portion 313 is correspondingly coupled to the plug glue coupling portion 322, the docking shield shell 21 and the plug shielding shell 31 can be connected. Respectively composed of a butting glue 22 and a plug glue 32 When the user needs to replace the docking shielding shell 21 or the plugging shielding shell 31, the user can remove the docking shielding shell 21 and the plugging shielding shell 31 according to the above-mentioned structure, so that they can be replaced by themselves. The effect.

In addition, when the male connector 3 and the female connector 2 are combined, the above-mentioned engaging portion 314 on the plug shielding shell 31 will abut the inner side wall of the mating shielding shell 21, thereby, the male connector can be lifted. The bonding strength of the connector 3 and the female connector 2 prevents the mating terminal 221 and the plug terminal 321 from being easily separated by external force, so as to stabilize the overall signal transmission process.

In addition, the structure of the above-mentioned bending wall portion 315 enables the plug shielding shell 31 to be more closely attached to the outside of the plug rubber body 32 when the plug-in rubber body 32 is combined, thereby improving the bonding strength of the two. At the same time, the bending wall portion 315 also It partially shields the butting gap 212 on the butting shielding shell 21, and the bent wall portion 315 can reflect the external electromagnetic wave through its bending state, easily change the direction of the external electromagnetic wave, and then assist the insertion of the shielding portion 311 to improve the overall shielding effect .

However, the above descriptions are only the preferred embodiments of the present model, and are not limited to the patent scope of the present model. Therefore, all simple modifications and equivalent structural changes made by using the present model description and schematic content should be the same. It is included in the scope of the patent of this new model and is combined to Chen Ming.
