[embodiment]
Electric connector of the present invention is used for connecting a kind of chip component (not shown).With reference to Fig. 1 and Fig. 2, electric connector 1 of the present invention mainly comprises insulating body 2, be assembled in the some conducting terminals 3 in the insulating body 2 and be assembled in sucking plate 4 on the insulating body 2.
Emphasis is with reference to Fig. 2 and Fig. 3, and insulating body 2 is rectangular structure on the whole, and it has base portion 20 and reaches by upwardly extending sidewall 21 around the base portion 20.Base portion 20 is provided with some terminal holes 200 and is used for assembling conducting terminal 3.Sidewall 21 be distributed in base portion 20 around, the end face 212 that it has the medial surface 210 adjacent with base portion 20, lateral surface 211 toward the outer side and is positioned at the top.The two ends of each medial surface 210 are provided with protrudes the locating convex block 2100 that medial surface 210 certain-lengths are used for the positioning chip element.Described locating convex block 2100 is positioned at four corners of insulating body 2.Wherein, be positioned at two locating convex blocks 2100 on the same sidewall 21 and be provided with burnishing surface in order to the described chip component of lateral register.Thereby offer downwards in end face 212 and to form a breasting face 213, thus breasting face 213 parallels with end face 212 and and end face 212 between have a height fall and form the drop face 214 perpendicular with breasting face 213 and end face 212 in the two ends of breasting face 213.Drop face 214 and adjacent medial surface 210 be common to form a drift angle 215.In addition, has certain distance between the locating convex block 2100 on the medial surface 210 of drop face 214 and place sidewall 21.The middle part of breasting face 213 place sidewalls 21 is provided with fluting 216, can be convenient to picking and placeing of chip component.
Emphasis is with reference to Fig. 2 and Fig. 4 to Fig. 7, and sucking plate 4 assemblings also are covered on the insulating body 2 the absorption plane 41 that it comprises the installation portion 40 around being positioned at and is positioned at middle part and the certain altitude that raises up.The edges at two ends of relative both sides of installation portion 40 stretches out respectively and protrudes a bearing and leaning portion 400, has thickness difference between bearing and leaning portion 400 and the installation portion 40, and bearing and leaning portion 400 is thinner than installation portion 40.Bearing and leaning portion 400 is positioned on the breasting face 213 on the insulating body 2 and with drop face 214 adjoins mutually, and bearing and leaning portion 400 sides form the breach 401 that matches with drift angle 215 on the insulating body 2.In present embodiment, drift angle 215 is the right angle with breach 401.In addition, the side of breach 401 is provided with another breach 402 corresponding to locating convex block 2100 places, avoids locating convex block 2100 so that absorption pulls 4.Described breach 401 and described another breach 402 are adjacent and jointly make described bearing and leaning portion 400 be continuous stepped.Be provided with a holding part 403 between two bearing and leaning portion 400 of homonymy, the two ends of holding part 403 respectively are provided with a snap fit 404 that is fastened on the insulating body 2.In addition, sucking plate 4 respectively is provided with two grooves 405 on the dual-side adjacent with bearing and leaning portion 400 place sides, the keeper 5 that cooperates with groove 405 is housed on the insulating body 2, and keeper 5 has the protuberance 50 that protrudes in the groove 405, and described keeper 5 separates setting with insulating body 2.
Can be found out by above description, the present invention since the bearing and leaning portion 400 by sucking plate 4 with the cooperating of breasting face 213 of insulating body 2 can realize the location of sucking plate 4 on insulating body 2.Simultaneously, drop face 214 and the medial surface 210 formed drift angles 215 of sidewall 21 cooperate the accurate location that has further guaranteed sucking plate 4 with breach 401 on the sucking plate 4.
