The present invention relates to an electrical connector comprising: an insulative housing having a plurality of passageways; and a plurality of contacts secured in the plurality of passageways of the insulative housing, each of the plurality of contacts having an angled body, an upper arm and a lower leg extending from the angled body, and a U-shaped plate secured to the angled body to together define a tubular structure for improved high-frequency characteristic.
Contacts for electrical connectors have given thickness and are usually made by stamping and forming planar contact stocks. Tubular contacts are preferred for increased coupling and decreased impedance in high-frequency applications as well as for better shielding effects. However, it is difficult and complicate to make contacts into desired tubular shapes by stamping and forming.
An electrical connector comprises: an insulative housing having a plurality of passageways; and a plurality of contacts secured in the plurality of passageways of the insulative housing, each of the plurality of contacts having an angled body, an upper arm and a lower leg extending from the angled body, and a U-shaped plate secured to the angled body; wherein the angled body has a first part, a second part bent from the first part, and a clip bent from the second part; and the U-shaped plate has a base, a first limb, and a second limb, the first limb is clamped between the first part and the clip, and the U-shaped plate and the second part of the angled body together form a tubular structure.
Referring to
Specifically, the angled body 22 has a first part 222, a second part 224 bent from the first part 222, and a clip 226 bent from the second part 224. The U-shaped plate 28 has a base 282, a first limb 284, and a second limb 286. The first limb 284 is clamped between the first part 222 and the clip 226. The U-shaped plate 28 and the second part 224 of the angled body 22 together form a tubular structure. The clip 226 may have a flared lower end 2262 for ease of mounting the U-shaped plate 28.
The U-shaped plate 28 is clear of an inner wall surface of the passageway 12. The contact 20 is secured in the passageway 12 by a barb 2222 of the first part 222 and a barb 2242 of the second part 224 of the angled body 22. The angled body 22 may have a stopper 228 and the passageway 12 may have a step at a bottom of a slot 122 thereof so that an inserting or stitching depth of the contact 20 is regulated by engagement between the stopper 228 and the step.
