TECHNICAL FIELD
[0001] The utility model relates to a connector especially high pressure connector shielding structure. BACKGROUND
[0002] At present, the shielding structure of high pressure connector is usually composed of shielding shell, shielding cover, shielding ring, etc. Its main function is to prevent electromagnetic interference and radio frequency interference, and to ensure the stability and reliability of signal transmission. The design and material selection of shielding structure will affect its shielding effect. There are three kinds of existing shielding structures. The first kind is that the wire shielding layer passes through the middle gap of the shielding cover and the shielding ring, and then the screw thread of the shielding shell extrudes each component to contact. However, once the screw thread is loose or one of the components is damaged, the shielding effect will decrease. The second kind of shielding structure is that the wire shielding layer passes through the middle gap of the shielding cover and the shielding ring, and then the shielding ring is deformed and fixed by pressure connection, and the shielding cover and the shielding shell are connected by the contact spring on the shielding cover. Although this method is reliable, the shielding cover is made by stretching a copper pipe and then punching out the spring, and the same shielding cover can only be matched with the same cable specification. Therefore, the processing and mold cost is high, and the number of molds is large. The third kind of shielding structure is that the wire shielding layer passes through the middle gap of the two shielding rings, and then the shielding rings are deformed and fixed by pressure connection, and then the shielding cover is installed in the shielding shell. The shielding cover and the shielding shell are directly connected by the outer wall. Finally, the wire passes through the middle spring of the shielding cover, so as to realize the overall connection of the wire shielding layer and the shielding shell. However, the shielding cover is punched out from a copper sheet strip, and there is no fixing structure when it is installed in the shielding shell. Once it is extruded by external force, the contact will be poor, the contact resistance will be large, and other risks will occur. SUMMARY

The embodiment in the basic utility model, all other embodiments obtained by the ordinary skill in the art without making the creative labor, belong to the range of protection of the utility model.
[0016] As Figure 1 , 2As shown, the figure includes a wire 6 connected in the shielded shell 1, the connection of the wire 6 with the shielded shell 1 is provided with a shielding structure, the shielding structure includes a plastic holder 2 fixedly connected on the shielded shell 1, a shielding cover 3 is sleeved on the plastic holder 2, a shielding ring one 4 is embeddedly connected in the shielding cover 3, a shielding ring two 5 is sleeved on the shielding ring one 4, the shielding cover 3 is provided with an elastic buckle 8, the shielding cover 3 is fixed on the plastic holder 2 to become an integral whole through the elastic buckle 8, the outer circle of the shielding cover 3 contacts the shielded shell 1, and the inner circle contacts the shielding ring one 4. The shielding cover is punched out of a copper sheet strip, compared with the existing way of punching out the elastic piece after stretching the copper pipe, the production efficiency is improved. The strip punching can realize continuous production, reduce the processing steps and time cost, and reduce the number of molds. The shielding cover is installed on the plastic holder, the shielding cover is fixed on the plastic holder to become an integral whole through the elastic buckle of the shielding cover, and the plastic holder can increase the structure on the insulating rubber core of the terminal, and is directly made into a part. The shielding cover can also be used as a fixing structure of the insulating rubber core and the shielded shell, which increases the holding force of the insulating rubber core and the shell, and reduces the mold cost of developing the shielding holder alone.
[0017] The outer circle of the shielding cover 3 is provided with a fish scale-shaped multi-point contact elastic piece 9. The contact mode of the shielding cover and the shielded shell is fish scale-shaped multi-point contact.
