Detailed Description

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 to 7, the gold needle assembly is used for a data module, and includes a plurality of gold needles 100 and a fixing seat 200, wherein the gold needles 100 are erected on the fixing seat 200, and are used for connecting a circuit board and a crystal head to realize signal transmission.

The quantity of day needle 100 is eight, and six of eight day needles all are equipped with the location portion, certainly also can all be equipped with the location portion on the eight day needles, the location portion is the rhombus, perhaps the location tooth 110 of location portion for protruding locating day needle, location tooth 110 is the bar form, in this embodiment, the location portion is the latter, just location tooth 110 deviates from day needle direction vertical extension from day needle 100 side and forms, certainly, location tooth 110 also can deviate from day needle direction slope extension from the day needle side and form.

The gold needle 100 further comprises a protruding part 120 and a fisheye part 130, the protruding part 120 is used for being connected with the crystal head, the fisheye part 130 is used for inserting the gold needle 100 into a circuit board, and the arrangement of the fisheye part 130 can avoid welding of the gold needle and the circuit board.

The fixing seat 200 comprises a first fixing seat 210 and a second fixing seat 220, the first fixing seat 210 comprises a first end 211 and a second end 212, a through hole 213 is formed between the first end 211 and the second end 212, in this embodiment, a connecting line direction between the first end 211 and the second end 212 is a length direction of the gold needle, and is also a left-right direction in which the gold needle 100 slides relative to the fixing seat 200, a connecting line direction perpendicular to the first end 211 and the second end 212 is a front-back direction in which the gold needle 100 slides relative to the fixing seat 200, a limit block 214 is arranged on the first end 211, a second limit groove 215 is formed between adjacent limit blocks 214, one end of the gold needle 100 close to the boss 120 is positioned in the second limit groove 215, the boss 120 abuts against the second limit groove 215 to limit the gold needle 100 from sliding towards the first end 211, a plurality of positioning grooves 216 and a pair of clamping grooves 217 are arranged on the second end 212, the positioning grooves 216 are matched with the positioning parts, when the positioning parts are in a diamond shape, the positioning grooves 216 are also in a diamond shape, at the moment, when the stress of the golden pins is too large, the diamond-shaped positioning parts have certain inclination, and are easy to deform, so that the diamond-shaped positioning parts extrude and slide towards the second end 212, and the contact between the crystal heads and the golden pins has certain influence, and the positioning parts adopt the strip-shaped positioning teeth in the embodiment, particularly when the positioning teeth are vertically connected with the side surfaces of the golden pins, the positioning grooves 216 are also in a strip shape generally, and are in right-angle butt joint with the side surfaces of the golden pins, so that the golden pins can be better limited from sliding towards the second end 212.
