Description

TECHNICAL FIELD

[0001] The utility model relates to the field of electrical connection, especially a high reliability liquid cooling shielded connector. BACKGROUND

[0002] The current new energy industry develops rapidly, and the connector is widely used in the efficient transmission and charging and discharging of electric energy. The connector needs good shielding effect. At present, in order to achieve good heat dissipation effect, the connector generally uses liquid cooling cable. However, there are some problems. Firstly, the current connector has large outer diameter, heavy weight and low space utilization rate. Because the liquid cooling pipe of the traditional structure is not matched with other components, the overall structure is not compact. Under the influence of external force, the connection is easy to loosen, and the liquid cooling passage is easy to be affected, so the reliability is poor. Secondly, the liquid cooling pipe and the shield cannot effectively cooperate. In order to ensure the liquid cooling effect, the electromagnetic shielding is not good, the equipment is easy to be disturbed, and the shielding protection is weak. In order to reduce electromagnetic interference, some connectors increase the wrapping of the conductor with multiple shielding materials, but this solution has the problem of high cost. SUMMARY

The tube hole of the liquid passing hose is a cooling liquid passage. The outer wall of the outer insulation skin is in interference fit with a shielding pressure ring in the shell and close to the terminal.

[0006] The shielding pressure ring is an electromagnetic shielding member formed by the interference fit of the shielding ring with the outer wall of the outer insulation skin. The outer wall of the shielding pressure ring is in contact with the shell, so that the external force borne by the shielding pressure ring can be uniformly dispersed to the shell.

[0007] The supporting steel ring is fixed to the outer wall of the end of the liquid passing hose. The supporting steel ring and the shielding pressure ring are radially opposite to each other. When the shielding ring is interference fit to form the shielding pressure ring, the supporting steel ring bears the pressure, so as to protect the smooth flow of the cooling liquid passage of the liquid passing hose.

[0008] The other end of the shell is provided with a terminal insertion hole.

The outer shielding cover is sleeved on the outer wall of the middle shielding layer. The outer wall of the outer shielding cover is in contact with the shell.

[0010] In some embodiments, the middle shielding layer connects the inner shielding layer of the liquid cooling cable and contacts the outer shielding cover for conduction, and the outer shielding cover is elastically pressed against the inner wall of the shell.

[0011] In some embodiments, the shielding wire of the inner shielding layer is first turned upward and then turned backward and wrapped around the outer circumferential wall of the outer insulation skin to form the middle shielding layer.

[0012] In some embodiments, the inner shielding layer is sleeved between the outer insulation skin and the inner insulation skin of the liquid cooling cable.

[0013] In some embodiments, the outer shielding cover includes a ring-shaped cover body sleeved outside the middle shielding layer, and the elastic sleeve of the cover body is elastically expanded to tightly connect the inner wall of the shell.

[0016] In some embodiments, the outer wall of the wire fixing tube of the shell is clamped with the outer cover, the tube hole end is connected with a sealing ring, the liquid cooling cable passes through the sealing ring into the wire fixing tube, the front plug tube of the shell is installed with a jack, and the rear end of the jack is connected with the terminal.

[0017] In some embodiments, the liquid cooling cable includes, from inside to outside, a liquid passing hose, a copper core wire, an inner insulation skin, an inner shielding layer, and an outer insulation skin; a supporting steel ring is arranged between the liquid passing hose and the copper core wire.

[0018] In some embodiments, the shielding ring is a circular ring, and the shielding ring is hexagonally pressed to form a shielding pressing ring with a regular hexagonal outer wall and a circular inner hole wall.
