Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of electric connector that the wafer module is electrically connected to printed circuit board (PCB) especially.

[background technology]

Have now and be used to electrically connect the electric connector of wafer module to printed circuit board (PCB), the plurality of conductive terminals and one that it generally comprises insulating body, be contained in the insulating body is fixed in locked instrument in the insulating body with the wafer module, and this locked instrument comprises the reinforced sheet that is articulated in the insulating body periphery, be articulated in reinforced sheet one end is used to compress the pressing plate of wafer module and be articulated in the driving lever that the relative other end of reinforced sheet is used to pin pressing plate.This locked instrument is because driving lever is long, and it is bigger to take up room, and is suitable for desktop computer, then inapplicable for laptop.

Laptop is fixed in the wafer module in the insulating body with cramp usually at present, as shown in Figure 1, it is a kind of cramp 2 of withholding wafer module (not shown), this cramp 2 is roughly rectangular, its part that presses on the wafer module is two leaf springs 21 of rectangle side, and after cramp 2 was assembled with insulating body (not shown), wafer module, heat abstractor (not shown) etc., meetings such as heat abstractor applied certain load force to cramp 2, make cramp 2 that strain take place, compress the wafer module.Because the coefficient of elasticity of this cramp 2 is bigger, if the power that is applied on the cramp 2 is too big, then can cause cramp 2 distortion too big, infringement wafer module limits to some extent so plant 2 pairs of carryings of cramp load force size thereon.

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

[utility model content]

The technical problem that the utility model solved provides a kind of electric connector that contains cramp, and this cramp can reduce electric connector to applying the requirement of load force thereon.

For solving the problems of the technologies described above, the utility model provides a kind of electric connector, be used to electrically connect the wafer module to printed circuit board (PCB), the cramp that it comprises insulating body, is contained in the plurality of conductive terminals in the insulating body and the wafer module is pressed into insulating body, wherein, add ons has been set up in the zone of described cramp cover wafers module.

Compared with prior art, the utility model is attached with add ons on cramp, this add ons can change the coefficient of elasticity of cramp, the coefficient of elasticity of cramp is diminished, make cramp can bear bigger power, enlarged the scope of cramp bearing capacity, thereby reduced being applied to the requirement of the load force on the cramp.

[embodiment]

See also Fig. 2 to shown in Figure 5, the utility model is an electric connector, this electric connector is used to electrically connect circuit board 4 and wafer module (not label), the cramp 7 that it comprises insulating body 5, is contained in the plurality of conductive terminals (not shown) in the insulating body 5 and the wafer module is pressed into insulating body 5.

Consult shown in Figure 3ly, insulating body 5 is by insulating material manufacturings such as rubber, and it is roughly rectangular, and insulating body 5 comprises base portion 50, has extended upward sidewall 51 around the base portion 50, and base portion 50 and sidewall 51 surround the host cavity 52 of accommodating the wafer module jointly.Base portion 50 is provided with the terminal containing slot of some one-tenth arranged, and conducting terminal is contained in the terminal containing slot, and the conducting terminal upper end has the contact site that contacts with wafer module push type, and the conducting terminal lower end is welded with tin ball (not shown).Be equipped with elastic arm 510 on the adjacent two side 51, this elastic arm 510 can be pushed the wafer module to a corner of insulating body 5 host cavities 52, with the positions wafer module.Insulating body 5 bottoms are provided with some projections (not shown), and when the tin ball bonding of conducting terminal bottom was connected to circuit board 4, projection was supported on the circuit board 4, prevent the fusing of tin ball excessively.

Consult Fig. 4 and shown in Figure 5, cramp 7 is roughly rectangular, is metal leaf springs in the present embodiment, the transition part 72 that it comprises holding parts 71, pressure section 73 and connects holding parts 71 and pressure section 73.Pressure section 73 is lower than transition part 72, can be pressed on the wafer module, transition part 72 tilts to extend upwardly to fixed part 71 from pressure section 73 two ends, fixed part 71 comprises kink 711 that extends from transition part 72 terminal bendings downwards and the extension that upwards is bent to form 712 that is provided with at interval in kink 711 terminal middle parts, forms the fluting 713 of collecting company's fitting 8 between the extension 712.At cramp 7 middle parts, roughly on pressure section 73, be provided with rectangular aperture 74, can distribute the heat that the wafer module produces when running.Be provided with add ons 75 in cramp 7 lower surface openings 74 both sides, this add ons 75 is made and is sticked on the cramp 7 for plastic material in the present embodiment.The width of add ons 75 and opening 74 roughly quite and extend to the two side of cramp 7.Add ons 75 can reduce the coefficient of elasticity of cramp 7, increases the bearing capacity of cramp 7.

Cramp 7 is mainly used in when the wafer module is positioned in the host cavity 52 of insulating body 5, withholds on the wafer module, guarantees well electrically contacting of wafer module and conducting terminal.This is because conducting terminal is that push type contacts and the contact site of conducting terminal upper end has elasticity with the wafer module, so when not having cramp 7 to withhold on the wafer module, the wafer module be easy to be upspring by conducting terminal or between the two contact closely do not cause poor electrical contact.

Consult Fig. 2, when assembling this electric connector, earlier the conducting terminal in the insulating body 5 is welded in the precalculated position on the circuit board 4, put into the wafer module then, at last cramp 7 is positioned on the wafer module, connector 8 is put into fluting 713, also be preset with perforate (not label) on the circuit board 4, cramp 7 and circuit board 4 are fixed together by connector 8.The add ons 75 of assembling back cramp 7 is connected on the wafer module.

It below only is preferred embodiment of the present utility model, in the utility model, add ons 75 is not limited to plastic material, it also can be metal material or some other material, it can adopt means such as stickup or welding to be attached on the cramp 7, and this add ons 75 can be located on the upper surface or lower surface of cramp 7, and other any improvement conversion of being done on the present embodiment basis also should not break away from the technical solution of the utility model.
