Yet along with the direction of chip module to high density, miniaturization develops, promptly the arrangement of the conducting terminal of electric connector is also more and more closeer.But, the conducting terminal of this prior art is in being assembled into the terminal hole of insulating body the time, conducting terminal is under pressure and moves downward, the direct die-cut formation of hangnail because of the base portion of conducting terminal, it is understood scratch or damages the terminal hole of insulating body when entering terminal hole madial wall, be easy to generate soft flocks and be damaged to conducting terminal self, cause to connect insecure phenomenon, thereby influence the electric connection of circuit board and chip module.

Given this, be necessary to provide a kind of improved electric connector in fact, to overcome the defective of above-mentioned electric connector.

[summary of the invention]

The purpose of this utility model is to provide a kind of connector terminals of easy to assembly and accurate positioning.

For solving the problems of the technologies described above, the utility model relates to a kind of electric connector, in order to electrically connect chip module to circuit board, it comprises the insulating body that is provided with terminal accommodation holes and is contained in conducting terminal in this insulating body, wherein conducting terminal be provided with holding parts, the docking section that extends upward from the upper end of holding parts and the afterbody that extends from the lower ends downward bending of holding parts, wherein, the holding parts both sides of conducting terminal are provided with hangnail, and described hangnail forms chamfering to avoid the swipe inwall of terminal accommodation holes of hangnail at its lateral border along its thickness direction.

Compared with prior art, the utlity model has following advantage: the holding parts of the conducting terminal of electric connector is provided with hangnail, and this hangnail can make conducting terminal enter smoothly and be positioned in the terminal hole of insulating body, and the inwall of the terminal hole of can not swiping.

[embodiment]

See also Fig. 1 and Fig. 2, the utility model electric connector 100 is in order to electrically connecting chip module 3 to circuit board 4, and it comprises insulating body 1 and is contained in conducting terminal 2 in this insulating body 1.

See also Fig. 4, this insulating body 1 rectangular structure, the terminal accommodation holes 12 that it is provided with the upper surface 10 that contacts with chip module 3, the lower surface 11 that contacts with circuit board 4 and runs through insulating body 1, above-mentioned conducting terminal 2 is contained in the terminal accommodation holes 12.Wherein, this terminal accommodation holes 12 limited post 122 of comprising long and narrow fixing conduit 120, being arranged in the neck 121 of fixing conduit 120 and adjoining fixing conduit 120 and upwards protrude out.

See also Fig. 3, conducting terminal 2 is one-body molded by punching press, and it comprises the holding parts 20 that is plate-like structure, from the upwardly extending docking section 21 of the upper end of holding parts 20 side and bend the afterbody 22 of extension downwards from the middle part of the lower end of holding parts 20.Wherein, the lower end of docking section 21 1 sides connects the support portion 24 that is strip structure by a kink 23, the top bending extension of self-supporting portion 24 goes out the cantilever 25 of level, cantilever 25 tilts to extend upward a contact site 26 that is provided with hook 27 in the one end, and this contact site 26 is used for electrically contacting with chip module 3.The transition part 28 that tilts by a undulate between holding parts 20 and the afterbody 22 is connected, and afterbody 22 is connected with circuit board 4.

Wherein, holding parts 20 is formed with the vertical fixing surface 29 of a rectangular plate-like structure, the upper end of the relative both side edges of fixing surface 29 and lower end are provided with some hangnails that outwards protrude out 30, along molding chamfering 300 on its thickness direction, this hangnail 30 contacts with fixed conductive terminals 2 in insulating body 1 in order to interfere mutually with the sidewall of the fixing conduit 120 of insulating body 1 mode of this hangnail 30 by punching press at its lateral border.

See also Fig. 4, when the utility model electric connector 100 is assembled into insulating body 1 with conducting terminal 2, conducting terminal 2 inserts the terminal accommodation holes 12 from the upper surface 10 of insulating body 1, chamfering 300 can guarantee can the not swipe inwall of terminal accommodation holes 12 of hangnail 30 in conducting terminal 2 insertion process, the hangnail 30 of its holding parts 20 cooperates with the respective inside wall interference of fixing conduit 120, the hangnail 30 of described upper end and lower end lays respectively at neck 121 both sides of fixing conduit 120, so conducting terminal 2 is positioned in the terminal accommodation holes 12, the madial wall of terminal accommodation holes 12 is close in the holding parts 20 of conducting terminal 2 and docking section 21; The cantilever 25 of conducting terminal 2 exceeds the upper surface 10 of insulating body 1, so that contact site 26 electrically contacts with chip module 3; The limited post 122 of terminal accommodation holes 12 can support the chip module 3 that presses down at utmost to protect conducting terminal 2; Afterbody 22 extends beyond lower surface 11, is welded on the circuit board by tin ball 40, thus the electric connection of realization circuit board 4 and chip module 3.
