[embodiment]
Below in conjunction with drawings and Examples the utility model is further described.
Please refer to Fig. 1, shown in Figure 2, the utility model electric connector comprises insulating body 1 and the terminal of being located in the insulating body 12, be used to electrically connect planar lattice array chip module 3 to circuit board 4, wherein chip module 3 is provided with sheet pin 30, and circuit board 4 is provided with some conductive spacers 40.
Insulating body 1 is provided with some accepting grooves 10, is provided with baffle plate 11 in the accepting groove, and accepting groove 10 is divided into two parts up and down.
Terminal 2 has certain elasticity, and is straight, can be shapes such as filament shape, sheet, combines with one-body molded mode (insertmolding) and baffle plate 11, and oblique arrangement is in insulating body 1; Terminal 2 comprises contact site 21 and following contact site 22, up and down contact site 21,22 upper and lower surface of stretching out insulating body respectively.
When connecting planar lattice array chip module 3 to circuit board 4 time, the last contact site 21 of terminal 2 and following contact site 22 compress mutually with the pad 40 of the sheet pin 30 of chip module 3 and circuit board 4 respectively and contact the electric connection of realization chip module 3 and circuit board 4.
Certainly, the following contact site of above-mentioned terminal also can be connected on the tin ball bonding on the circuit board by being connected (as shown in Figure 3) with tin ball 5 again, to realize the electric connection of electric connector and circuit board.
Fig. 4, Figure 5 shows that the 3rd embodiment of the utility model electric connector, be with the difference of first embodiment, in the present embodiment, baffle plate 11 is provided with a through hole 110, terminal 2 is contained in the through hole 110, and terminal 2 one sides are provided with the tongue piece 23,24 that inclined in opposite directions is stretched out, make terminal 2 one sides form an opening 25, opening 25 can match with the baffle plate 11 of insulating body 1, two tongue pieces 23,24 of terminal are held in the upper and lower surface of plate washer 11 respectively, make terminal 2 and insulating body 1 be retained on together.
Figure 6 shows that the 4th embodiment of the utility model electric connector, be that with the difference of the 3rd embodiment in the present embodiment, two tongue pieces the 23, the 24th on the terminal 2 are gone out from the centre position of terminal, rather than determined from a side blow of terminal 2.
