Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
Referring to fig. 1-3, a positive and negative plug-in type electromagnetic interference resistance connector includes a housing 1, an upper cover assembly, a lower cover assembly and a middle clip shielding element 6, the housing 1 is sleeved outside the upper cover assembly, the lower cover assembly and the middle clip shielding element 6, and an upper cover portion 2 is fixedly connected with a lower cover portion 4; the upper cover assembly comprises an upper cover part 2 and a plurality of upper terminals 3, the upper terminals 3 are arranged on the upper cover part 2 at intervals, and the upper terminals 3 penetrate through the upper cover part 2; the lower cover assembly comprises a lower cover part 4 and a plurality of lower terminals 5, the lower terminals 5 are arranged on the lower cover part 4 at intervals, and the lower terminals 5 penetrate through the lower cover part 4; the middle clamping shielding piece 6 is arranged between the upper cover part 2 and the lower cover part 4, a plurality of annular contact pieces 7 are arranged at intervals on the middle clamping shielding piece 6, the annular contact pieces 7 are vertically arranged, a plurality of first through holes 8 for the upper parts of the annular contact pieces 7 to penetrate through are arranged at intervals on the upper cover part 2, and a plurality of second through holes 9 for the lower parts of the annular contact pieces 7 to penetrate through are arranged at intervals on the lower cover part 4; upper cover portion 2 interval is equipped with buckle hole 10 and last buckle piece 12, and lower cover portion 4 interval is equipped with lower buckle piece 13 that is used for with last buckle hole 10 joint and is used for with the lower buckle hole 11 of last buckle piece 12 joint.
The utility model discloses a shell 1, well clamp shield 6 have simplified the shielded structure, through setting up cyclic annular contact piece 7, have increased area of contact, when being connected with the joint that the external world corresponds, have improved electromagnetic interference resistance's effect.
