The invention discloses a shielding structure for a circular electric connector, and is characterized in that the shielding structure is formed by a clamping ring, a tail sleeve, a shielding spring ring and a tail casing in a sleeved manner; the tail sleeve is a stepped shaft sleeve provided with a ring-shaped clamping groove A and a stepped hole; the shielding spring ring is provided with clamping rings at the two ends thereof, and an elastic spring sleeve provided with a concave camber is arranged in the middle of the shielding spring ring; the tail casing is a stepped shaft sleeve, and a ring-shaped clamping groove B is formed in the tail casing; and the shielding spring ring is sleeved in the stepped hole of the tail sleeve, and the clamping rings at the two ends of the shielding spring ring are clamped with two ring-shaped grooves. Compared with the prior art, the shielding structure provided by the invention is simple in structure, low in manufacturing cost and convenient to mount, well meets the demand on convenient and quick filed mounting, is high in the reliability of the connection of cable shielding layers, and ensures excellent mechanical and electrical performances.
Description
technical field [0001] The invention relates to the technical field of electric component plugging, in particular to a shielding structure suitable for circular electric connectors. Background technique [0002] With the continuous development of circular electrical connectors, the application of circular electrical connectors in the fields of new communication technology and new audio-visual equipment is becoming more and more extensive, and the requirements for the connection of electrical connectors are also getting higher and higher. It is becoming more and more important for connectors to have shielding. The electrical connector has a shielding function, which can ensure the integrity of the signal transmission of the electrical connector after the electrical connector is reliably connected to the cable shielding layer, and reduce external interference and loss. [0003] Because the shielding structure of the electrical connector in the prior art is complicated, the ma...
