Abstract

The utility model discloses an electric connector which comprises an isolation body and a plurality of conductive terminals contained inside the isolation body; wherein the conductive terminals are provided with contact parts contacting a chip module in a compression mode; and the incline direction of a part of contact parts of the conductive terminals and the other parts of the contact parts of the conductive terminals is opposite approximately. Compared with prior art, the electric connector of the utility model causes that the incline direction of a part of contact parts of the conductive terminals and the other parts of the contact parts of the conductive terminals is opposite approximately, so the force received by the chip module in the horizontal direction in the compression process of the chip module and the contact parts of the conductive terminals can be reduced or eliminated so as to avoid the damage of a side wall; as a consequence, favourable electrical connection of the chip module and the circuit board is ensured.

Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, and especially a kind of being used for compressed the electric connector that contacts mutually with the planar lattice array chip module.

[background technology]

Electric connector of planar grid array generally uses with the planar lattice array chip module, and realizes contacting of both conducting positions with compress mode between this connector and the chip module, and reaches stable telecommunication transmission between the two.

The electric connector of traditional planar lattice array, as shown in Figure 1 and Figure 2, the metal upper casing 1 and the metal lower shell 2 that comprise mutual flexible connection, be contained in the base 3 that is used for carries chips module 6 in the metal lower shell 2, be contained in the conducting terminal 4 in the base 3, and be fixed in metal lower shell 2 one sides to fasten the rocking bar 5 of metal upper casing 1 and metal lower shell 2, wherein an end 41 of conducting terminal 4 compresses mutually with chip module 6 and contacts, the other end 42 is welded on the circuit board 7, the structure that positioning chip module 6 is arranged on the base, promptly sidewall 31.This electric connector moral defective is: because conducting terminal 4 compresses the contact jaw 41 of contact all towards lopsidedness mutually with chip module 6, thereby make the contact jaw 41 at chip module 6 and conducting terminal 4 compress in the process that contacts mutually, the bottom of chip module 6 can be subjected to a corresponding to power F of the incline direction with contact jaw 41, produce the trend of sliding, thereby, chip module 6 just can push the sidewall 31 of base, oppose side wall 31 brings certain destruction (as shown in Figure 3), when serious, may make sidewall 31 fractures, can cause the guiding access of chip module 6 not contact like this with conducting terminal 4, thereby, can have influence on the electric connection of chip module 6 and circuit board 7.

Therefore, be necessary to design a cenospecies electric connector, to overcome above-mentioned defective.

[summary of the invention]

The novel purpose of the utility model is to provide a kind of novel electric connector, to guarantee the good electric connection of chip module and circuit board.

For achieving the above object, the utility model electric connector comprises insulating body and is contained in the interior plurality of conductive terminals of insulating body, wherein be formed with sidewall on the insulating body, conducting terminal is provided with the contact site that compresses contact with chip module mutually, and the contact site of a part of conducting terminal is roughly opposite with the contact site incline direction of another part conducting terminal.

Compared with prior art, the utility model electric connector is roughly opposite with the contact site incline direction of another part conducting terminal by the contact site that makes a part of conducting terminal in the conducting terminal, to reduce or to eliminate the suffered in the horizontal direction power of contact site compression process chips module at chip module and conducting terminal, avoid the damage of oppose side wall, thereby guarantee the good electric connection of chip module and circuit board.

[embodiment]

With reference to the accompanying drawings the utility model electric connector is made and further describing.

Comprise insulating body 10, be contained in the plurality of conductive terminals 20 in the insulating body 10 with reference to Fig. 4 the utility model electric connector, this electric connector is used to electrically connect chip module 30 and circuit board 40, wherein, chip module 30 is provided with the pad (not shown) of compressing contact with the contact jaw of conducting terminal 20 mutually.

Insulating body 10 comprises pedestal 11 and the sidewall 12 that extends straight up from the pedestal outer rim, wherein is provided with some accepting grooves 13 in the pedestal, and accommodating conducting terminal 20, sidewall 12 has chip module 30 is positioned at effect on the pedestal 11.

Conducting terminal 20 is provided with and the contacted contact site 21 of going up of the pad of chip module 30, and the following contact site 22 that welds mutually with circuit board 40.

In the time of in the accepting groove 13 that conducting terminal 20 is assembled in insulating body 10, make the last contact site 211 of a part of terminal roughly opposite with the incline direction of the contact site 212 of remainder terminal, like this when the chip module and the last contact site 21 of conducting terminal 20 compress contact mutually, the last contact site 211 of part terminal is roughly opposite with 212 pairs of power that chip module acted on of last contact site branch force direction in the horizontal direction of another part terminal, thereby the power power in the horizontal direction of 20 pairs of chip modules 30 of monolithic conductive terminal reduces or eliminates, so can avoid chip module oppose side wall 12 to damage, thereby guarantee that chip module 30 and circuit board 40 well electrically connect.

Figure 5 shows that another embodiment of the utility model electric connector.Be with first kind of embodiment difference: in the present embodiment, the pedestal 11 ' of insulating body 10 ' is provided with first accepting groove 131 ' and second accepting groove 132 ', and first accepting groove 131 ' and second accepting groove 132 ' roughly tilt in opposite direction, when conducting terminal 20 ' assembling and the first terminal accepting groove 131 ' and second accepting groove 132 ', the last contact site 21 ' of conducting terminal 20 ' is inclined in opposite directions roughly also, thereby, can produce the effect identical with first embodiment, in addition, the following contact site 22 ' of conducting terminal 20 ' also compresses contact mutually with circuit board 40 ', realizes the good electric connection of chip module 30 ' and circuit board 40 '.

Certainly, persons skilled in the art can be understood, and the utility model electric connector also can be applicable to electrically connect other electronic building brick, as circuit board and circuit board etc.
