Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of novel electric connector, and it can not increase on the circuit board under the situation of earth terminal, eliminates the static that chip produces at work, realizes normal signal transmission between chip and the circuit board.

In order to reach above-mentioned creation purpose, the utility model electric connector is used to connect chip and circuit board, comprises an insulating body, some signal terminals and at least one earth terminal, and earth terminal can be contacted with wherein signal terminal.

Compared with prior art, the utility model electric connector, it can not increase on the circuit board under the situation of earth terminal, eliminates the static that chip produces at work, realize normal signal transmission between chip and the circuit board, also guaranteed the normal useful life of chip simultaneously.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

Referring to figs. 1 through Fig. 5, the utility model electric connector 1 is used to connect chip 6 and circuit board (not icon), and it comprises insulating body 2, some signal terminals 4, earth terminal 5 and a metal buckle 3.

Wherein, insulating body 2 comprises that our department 21 reaches by extended the first side wall 22 on our department's 21 1 side direction, these the first side wall 22 projecting inward several collude fixture block 221, in order to limit chip 6 moving in vertical direction, opposite side extends second sidewall 23 relatively, this second sidewall 23 is provided with a holddown groove 231, be used for fixing metal buckle 3, a location division 24 is upwards respectively extended in four corners in our department 21 in the two side, be used to limit chip 6 moving in the horizontal direction, be arranged with a groove 211 downwards at our department's 21 middle positions, be used to accommodate earth terminal 5, this groove 211 is provided with the first terminal accepting groove 2111 and second terminal containing slot 2112 and two earth terminal holes 2113, be relatively set with two rows in the both sides of our department between the two side 21 and accommodate the 3rd terminal containing slot 25 of signal terminal 4, be used for fixing and accommodate signal terminal 4.

Signal terminal 4 connects chip 6 and circuit board (not icon), but transmission signals destatics with leading, the junction 41 that comprises outstanding insulating body 2 our department 21 upper surfaces, be positioned at our department's 21 lower surfaces and the weld part 42 that welds mutually with circuit board (not icon), and the holding parts 43 that connects junction 41 and weld part 42, holding parts 43 is immobilizated in the insulating body 2, in order to fixed signal terminal 4.

Earth terminal 5 is contained in the groove 211, comprise and be flat base portion 51, by base portion 51 elastic contact arm 52 that connects with earth point (not shown) chip 6 that extend obliquely, and by the contact site 53 of base portion 51 1 sides near extension downwards of elastic contact arm 52 1 ends and bending, it is contained in second terminal containing slot 2112, before placing, chip 6 just contacts, in order to lead the static that produces except that chip with signal terminal 4 wherein.And by the fixed part 54 of base portion 51 away from the downward extension of elastic contact arm 52 1 ends, the two earth terminal holes 2113 that it is contained in groove 211 are used for fixing earth terminal 5.

Metal buckle 3 is contained in the described holddown groove 231, comprise two matrixes 31,31 ', wherein matrix 31 is provided with one and colludes card division 32, can match with the fixture block 221 that colludes of insulating body 2, be used for fixing chip 6 moving in vertical direction, matrix 31 ' stably is immobilizated in the holddown groove 231 of insulating body 1 metal buckle 3 to being arranged with first,

second holding parts
