Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, especially a kind of electric connector that electrically connects between chip module and the circuit board of reaching.

[technical background]

Figure 1 and Figure 2 is a kind of electric connector relevant with the utility model 10, and it comprises insulating body 11 and is assembled in framework 13 on the insulating body 11 by screw 12.

Insulating body 11 is roughly rectangular, and its middle part is provided with plurality of conductive terminals (not shown).One roughly rectangular framework 13 is located at the upper surface of insulating body 11, accommodates the cavity 15 of chip module (not icon) with formation.Four corner correspondences of insulating body 11 and framework 13 are provided with four through holes 110,130, pass through hole 110,130 by screw 12 insulating body 11 and framework 13 are linked together.Screw 12 comprises the double-screw bolt 121 that a head 120 and a diameter are littler than head 120, and this screw 12 up passes from the bottom surface of insulating body 11 and tightens, so the head 120 of screw 12 places the bottom of insulating body 11.

Because insulating body 11 and framework 13 need link together the two by screw 12 is set in addition, so the electric connector 10 of this structure can increase manufacturing costs; Secondly needs are changed framework 13 in order to adapt to different big or small chip modules sometimes, at this moment then need to operate and screw 12 could be pulled down from the bottom surface of electric connector 10, and then take off framework 13, because at this moment electric connector 10 has been welded on the circuit board (not icon), so can't retract framework 13 at all.

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, and it can reduce the manufacturing cost of electric connector, and pulls down than being easier to framework is assembled on the insulating body of electric connector and from this insulating body.

In order to realize solving the problems of the technologies described above, the utility model provides a kind of electric connector, comprising: be provided with the plurality of terminals accepting groove insulating body, be located at the plurality of conductive terminals in the terminal containing slot and be mounted on the insulating body and form the framework of a host cavity with insulating body; Wherein, insulating body is provided with the fixture with the framework secure fit, and each fixture is made up of the plurality of elastic trip, and this elastic clamping hook elastically deformable is so that take off framework on the body that insulate.

Compare with correlation technique, insulating body of the present utility model is provided with the fixture that cooperates with framework, each fixture is made up of at least one pair of elastic clamping hook, when needs are changed framework, only need promote elastic clamping hook gently and make its strain can open this fixture and framework is taken out.

[embodiment]

See also Fig. 3 to shown in Figure 6, the utility model is a kind of electric connector, in order to reach the electric connection between chip module (not icon) and the circuit board (not icon), this electric connector comprises insulating body 2, is located at the framework 3 that the plurality of conductive terminals (not shown) and in the insulating body 2 is fixed with insulating body 2 assemblings.

Insulating body 2 is roughly rectangular, and its middle part is provided with some terminal containing slots (not shown) that array is provided with that are, and is provided with the conducting terminal that can electrically connect chip module and circuit board in this terminal containing slot.Four corners of insulating body 2 are provided with the structure that can cooperate with framework 3.Wherein be provided with fixture 21 in a pair of diagonal two ends of insulating body 2, each fixture 21 is arranged on the insulating body 2 around the rounded hole 20, form four elastic clamping hooks 211 that evenly are provided with in extending upward of this hole 20 on every side, the holding part 2110 that this elastic clamping hook 211 cooperates with framework 3 is provided with in the opposite direction, and holding part 2110 tops also are provided with inclined plane 2111.In the present embodiment, hole 20 is the through hole on a perforation insulating body 2 upper and lower surfaces, elastic clamping hook 211 is arranged at the elastic force that can increase this elastic clamping hook 211 of operation all around in hole 20.Shape at the utility model mesopore 20 is not limited to circle, and it can one is square or other shape.Another is provided with the projection 22 that projects upwards insulating body 2 to cornerwise two ends.

Framework 3 rectangular shapes are located at the upper surface of insulating body 2, with the insulating body 2 common host cavities 4 of accommodating chip module that form.Four corners of framework 3 are provided with

hole

31,32 to cooperate with 2 fixture 21 or projection 22 on the insulating body.Fixture 21 positions of framework 3 corresponding insulating bodies 2 are provided with accommodation hole 31, be provided with the boss 310 that cooperates with elastic clamping hook 211 in the accommodation hole 31, this boss 310 just and the holding part 2110 mutual buckles of elastic clamping hook 211 so that elastic clamping hook 211 with can not move in vertical direction after boss 310 cooperates.Accommodation hole 31 is provided with guide surface 311 near an end of insulating body 2, makes things convenient for elastic clamping hook 211 to insert in the accommodation hole 31.Projection 22 positions of framework 3 corresponding insulating bodies 2 are provided with shrinkage pool 32, and projection 22 is inserted in the shrinkage pool 32, with positioning frame body 3 during assembling.

Framework 3 is loaded on the insulating body 2 from insulating body 2 upper set, because holding part 2110 tops of elastic clamping hook 211 are provided with inclined plane 2111, the accommodation hole 31 of framework 3 is provided with guide surface 311, so elastic clamping hook 211 is easy to be extruded and insert in the accommodation hole 32 along guide surface 311, when holding part 2110 bottom surfaces of elastic clamping hook 211 with after 310 of boss in the accommodation hole 32 contact, elastic clamping hook 211 recover natures and with boss 310 butts, so far, framework 3 is snapped on the insulating body 2.After electric connector is welded in circuit board, when changing framework 3 as needs, then only the holding part 2110 of elastic clamping hook 211 need be pushed to the center in hole 20 and can be made holding part 2110 disengaging boss 310, upwards mention framework 3 again, framework 3 is taken off from insulating body 2.

The utility model fixture 21 can with insulating body 2 integrated injection moldings, can reduce manufacturing cost, and this elastic clamping hook 211 can be out of shape, framework 3 ratio when taking off is easier to.

Below only be preferred embodiment of the present utility model, 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.
