Referring to fig. 1 and 2, an outer conductor structure for an ethernet connector includes an outer conductor base 1 and a connection ring 2, the connection ring 2 is fixed on one side of the outer conductor base 1, and at least one pair of connection arms 3 are fixed between the outer conductor base 1 and the connection ring 2, the pair of connection arms 3 being symmetrically disposed along an axis of the outer conductor base 1. The clearance between two adjacent connecting arms 3 constitutes accommodation space 4, the accommodation space 4 internal fixation has first contact lug 5 and second contact lug 6, in order to strengthen the holding power of first contact lug 5 and second contact lug 6, the one end of first contact lug 5 is fixed on go-between 2, the other end of first contact lug 5 extends along go-between 2 towards the direction that outer conductor base member 1 is located, the one end of second contact lug 6 is fixed on outer conductor base member 1, the other end of second contact lug 6 extends along outer conductor base member 1 towards the direction that go-between 2 is located, and first contact lug 5 and second contact lug 6 adjacent interval arrangement and accommodation space 4. By adopting a design in which the direction of extension of the first contact lug 5 is opposite to the direction of extension of the second contact lug 6, the influence of the mechanical forces to which the first contact lug 5 and the second contact lug 6 are subjected during the mounting of the outer conductor structure into the mating connector is advantageously reduced. In order to further improve the stability of the outer conductor structure when connected with the mating connector, a plurality of connecting arms 3, first contact lugs 5 and second contact lugs 6 are mounted on the outer conductor structure, and the connecting arms 3, the first contact lugs 5 and the second contact lugs 6 are arranged alternately along the circumferential direction of the connecting ring 2.

Specifically, in order to improve stability of the outer conductor structure, the connecting ring 2, the connecting arm 3 and the outer conductor base body 1 are integrally formed by sheet metal stamping, the first contact lug 5 and the connecting ring 2 are fixedly connected by spot welding, the second contact lug 6 and the outer conductor base body 1 are fixedly connected by spot welding, and a fixing mode of spot welding is adopted to improve stability of connection of the first contact lug 5 and the connecting ring 2 and stability of connection of the second contact lug 6 and the outer conductor base body 1. The welded structure has strong overall integrity, high rigidity and good overall performance because the welding is a connection between metal atoms, and is free from excessive deformation due to the change of the gap under external force. The outer conductor matrix 1 and the connecting ring 2 form stamping parts, so that the outer conductor matrix 1 and the connecting ring 2 are integrally formed through sheet metal stamping, the stability of an outer conductor structure is improved, or the stamping parts of the outer conductor matrix 1 are improved, the matched stability of the outer conductor matrix 1 and the internal insulating part 13 is improved, or the connecting ring 2 forms stamping parts, the matched stability of the connecting ring 2 and the connector is improved, and the manufacturing cost of an outer conductor contact element can be obviously reduced due to the arrangement of the stamping type structure.

After the outer conductor structure is inserted into the mating connector, the contact area is in close contact with the inner wall of the outer conductor of the mating connector, and the contact area is preferably arranged to be an arc surface so as to realize a stable signal transmission function.

Referring to fig. 4 and 5, a plurality of stopper protrusions 9 for restricting the insulator 13 are fixed to the inner wall of the outer conductor base 1, and the plurality of stopper protrusions 9 are symmetrically arranged along the axis of the outer conductor base 1.

In some embodiments, at least one pair of stop lugs 9 are fixed on the inner wall of the outer conductor base 1, and the stop lugs 9 limit the two ends of the insulating member 13, so as to improve the assembly stability of the insulating member 13 and the outer conductor base 1. To further improve the robustness between the outer conductor base 1 and the connector, a front stop block 10 is fixed to the outer conductor base 1, a front stop groove 11 is provided on the side of the front stop block 10 close to the connection ring 2, and the front stop block 10 is made of an elastic material. The through hole for embedding the front stop block 10 is formed in the connector shell relatively, when the outer conductor substrate 1 is embedded into the connector, the inner wall of the connector is abutted against the front stop block 10, so that the front stop block 10 elastically deforms until the front stop block 10 reaches the through hole formed in the connector, after the front stop block 10 rebounds, the front stop groove 11 side limits the connector, so that the connector cannot advance, the outer conductor structure is difficult to separate from the connector, and the connection stability of the outer conductor structure and the connector is improved.

And the fixing manner of spot welding is adopted to improve the connection stability of the first contact lug 5 and the connecting ring 2 and the connection stability of the second contact lug 6 and the outer conductor base body 1. The design that the protruding directions of the first contact lug 5 and the second contact lug 6 extend are opposite, in the process that the outer conductor structure is installed into the matched connector, the influence of mechanical force suffered by the first contact lug 5 and the second contact lug 6 can be reduced, the matched stability of the connector and the outer conductor structure is improved, the probability of looseness of the Ethernet connector is reduced, and accordingly the anti-seismic performance of the Ethernet connector is improved.
