[0002] With the increase of electronic product quantity, the signal interference around the connector is more and more. In order to ensure the high quality transmission of signal, it is necessary to increase the shielding cover in the connector. The shielding effect of the connector is greatly affected by the shielding switching contact effect of cable-connector. The existing cable shielding structure is in elastic contact with the connector shielding cover after the cable part is crimped with the shielding ring. The size of the terminal fixing and the shielding contact part is large in this connection mode, so the size of the connector itself cannot be too small, otherwise the contact space of the shielding cover spring piece cannot be accommodated. In different use scenarios, the structure of the connector needs to be controlled smaller and smaller, so a new connector structure and a new shielding connection mode are needed. SUMMARY

[0008] The shielding cable is installed in the cable mounting hole, the shielding layer of the shielding cable is crimped between the shell and the shielding outer ring, and the shielding cable is connected with the power plug-in piece.

[0009] The technical scheme that the shielding layer of the shielding cable is crimped between the shell and the shielding outer ring is adopted in the present scheme, compared with the switching mode of cable-shielding ring-shielding cover in traditional connector, the contact space of shielding cover spring piece is saved, the size of the connector is reduced, and it is suitable for use in different environments. The crimping connection mode is more stable than the spring piece connection, and the contact effect is good.

[0010] Further technical solutions are that the shell comprises a needle terminal sheath and a shielding cover.

[0011] The needle terminal sheath is installed in the shielding cover.

[0014] Further, the power tab is provided with a protruding portion at the rear portion.

[0015] The needle terminal sheath is provided with a limiting device matched with the protruding portion of the power tab.

[0016] The power tab is fixed by the limiting device of the needle terminal sheath, which eliminates the secondary locking structure of the terminal, further optimizes the overall size of the connector, and reduces the complexity of the overall structure.

[0017] Further, the needle terminal sheath comprises a first sheath assembly and a second sheath assembly.

[0018] The first sheath assembly and the second sheath assembly are connected by buckling.

[0019] The buckling connection has the effect of facilitating disassembly and facilitates the installation of the power tab.

[0021] The first shielding cover assembly and the second shielding cover assembly are connected by buckling.

[0022] Further, the connector shielding assembly further comprises an adapter spring, which is arranged on the opposite two surfaces of the shielding cover.

[0023] Since the shielding cover needs to be further connected with the board end or the adapter end shielding, the adapter spring can be used to fix and connect.

[0024] Compared with the prior art, the utility model has at least the following beneficial effects: the shielding and conduction of the utility model are directly crimped from the cable shielding layer to the shell shielding cover, the shielding and conduction performance is reliable, has good electromagnetic shielding efficiency and mechanical strength, the shielding is directly crimped from the cable to the shielding, compared with the traditional connector crimping mode of cable-shielding ring-shielding cover, the contact space of the shielding cover spring piece is saved, and the connector size is further reduced; further, the power tab of the application is fixed by the limiting device in the terminal sheath, the secondary locking structure of the terminal is saved, and the overall size of the connector is further optimized. The size of the connector can be reduced while ensuring good shielding effect. BRIEF DESCRIPTION OF DRAWINGS
