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 chip module.

[background technology]

Occurred a kind of chip module of LGA type now on some electronic product (as computer), the guiding access of this chip module is a washer-shaped, and the electric connector that is connected on the butt joint electronic building brick is provided with the conducting terminal that contacts with the guiding access compression.The electric connector of prior art, this electric connector comprises the insulating body that is provided with terminal containing slot and is contained in the interior conducting terminal of terminal containing slot, described conducting terminal is provided with two contact sites that protrude in insulating body, described chip module contacts by compressing mutually with two contact sites of conducting terminal with the butt joint electronic building brick, thereby realize chip module and dock being electrically conducted of electronic building brick, but this design is when installing chip module, easily cause the contact site overflexing of conducting terminal, positive force to chip module is excessive, after long-term compression, easily cause the damage of terminal and chip module, thus the electric connection between the influence butt joint electronic building brick.

Mostly adopt the method for directly establishing protrusion on insulating body establishing supporting surface on the insulating body, comprise an insulating body 1 and conducting terminal 2 as electric connector as described in Fig. 1 to Fig. 2, wherein insulating body 1 is provided with side 11.Insulating body 1 is provided with terminal accommodation hole 12 to accommodate conducting terminal 2, is hole wall 13 around the terminal accommodation hole 12.On insulating body 1, be provided with a protuberance 14 as supporting surface to support the butt joint electronic building brick.This method is because the restriction of protrusion size, and it is not good to support effect, and has wasted the space.

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 guarantee stable electric connection between the two butt joint electronic building bricks.

For achieving the above object, the utility model electric connector, it can contact with the compression of butt joint electronic building brick, comprise insulating body and conducting terminal, insulating body is provided with the plurality of terminals accommodation hole, described terminal accommodation holes is formed by first hole wall and second hole wall, and conducting terminal is provided with the elastic portion that protrudes in described hole wall, it is characterized in that: first hole wall of at least one side of described terminal accommodation hole is higher than second hole wall.

Compared with prior art, the utility model electric connector can not cause the damage of conducting terminal and chip module easily, can guarantee and dock between the electronic building brick to electrically connect preferably, and the energy conserve space, raising supports effect.

[embodiment]

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

Extremely shown in Figure 6 with reference to Fig. 3, the utility model electric connector, being used to electrically connect two butt joint electronic building bricks (can be planar grid array chip module is connected to circuit board, equal icons not, certainly, also can be other butt joint electronic building brick, as connect two circuit boards etc.), this electric connector comprises insulating body 1 and conducting terminal 2.

Described conducting terminal 2 is positioned at the terminal accommodation hole 12 of insulating body 1, comprise fixed part 21 and the elastic portion 22 and the contact site 23 that extend to two ends by fixed part 22, in the present embodiment, conducting terminal comprises two contact sites, can realize bilateral compression contact, described two elastic portion 22 is bent to form in the same direction, can compress contact mutually with the butt joint electronic building brick.

Insulating body 1 is provided with plurality of terminals accommodation hole 12, described terminal accommodation hole 12 reaches second hole wall 14 ' that intersects with first hole wall 13 ' by first hole wall 13 ' and forms, first hole wall 13 ' of described terminal accommodation hole 12 1 sides is higher than described second hole wall 14 ', like this, can increase the deformation space of conducting terminal 2 elastic portion 21, and described first hole wall 13 ' is for preventing to dock the supporting surface of electronic building brick overvoltage.First hole wall 100 of the terminal accommodation hole 12 of electric connector both sides all is higher than described second hole wall 101, also can be highly identical with second hole wall 14 ' at opposite side first hole wall 13 ', on insulating body, establish-protuberance to be to support the butt joint electronic building brick.Described two elastic portion 22 is positioned at same second hole wall 14 ' top, forms one with first hole wall 13 ' and allows bit space.Described second hole wall 14 ' is located at conducting terminal 2 overbending directions.

With reference to shown in Figure 7, second embodiment for the utility model electric connector, itself and the first embodiment difference are: described two elastic portion 23 is bent to form in the opposite direction, and described two elastic portion 22 is positioned at different second hole walls 14 ' top, forms one with first hole wall 13 ' and allows bit space.It also can reach the identical effect of the foregoing description.

The utility model electric connector because hole wall is set to supporting surface, can prevent the connected components overvoltage, can not cause the damage of terminal and chip module easily, energy guarantees and docks between the electronic building brick to electrically connect preferably, and the energy conserve space, and raising supports effect.
