Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of conducting terminal of chip module to circuit board that be used for connecting especially.

[technical background]

Along with the direction of chip module to high density, miniaturization develops, arranging of the conducting terminal of electric connector is also more and more closeer.Existing conducting terminal is one-body molded by punching press, and it comprises: base portion, the connecting portion that extends from the upper end of base portion one side, the elastic portion of extending in the lateral margin bending of the bottom of connecting portion, cantilever that the bending of own elasticity portion extends upward the formation level, in the end tilts of cantilever extend contact site, the transition part that extends downwards from the root edge of base portion and the weld part that is used to connect the tin ball from the transition part bending.Wherein, the weld part of existing all conducting terminals is that when being assembled in same row's terminal accommodation holes, the weld part of conducting terminal is arranged in a row to the same side of base portion bending.In order to guarantee that adjacent tin ball can not produce short circuit in when welding, weld part must keep certain spacing each other, so the terminal that this electric connector held is limited, thereby is unsuitable for the trend of the highdensity development of chip module.

Therefore, necessary existing electric connector is improved to overcome the aforementioned disadvantages of prior art.

[utility model content]

The purpose of this utility model is to provide a kind of can effectively increase the arrange electric connector of density of terminal.

The purpose of this utility model is achieved through the following technical solutions: a kind of electric connector, it comprises insulating body that is provided with the receiving space that is used for accommodating chip module and the plurality of conductive terminals that is installed on insulating body, each conducting terminal comprises the connecting portion that extends into receiving space, is fixed on base portion and weld part in the insulating body, be positioned at same row conducting terminal weld part respectively alternately to a side of base portion or relatively the opposite side bending to form two row's weld parts.

Compared to prior art, the utility model electric connector has following beneficial effect: the weld part of same row's conducting terminal of the utility model electric connector respectively alternately to the front and back of base portion two lateral bucklings forming two rows, alternately the weld part of arranging can increase the density of conducting terminal on to greatest extent.

[embodiment]

The utility model electric connector is widely used in and connects chip module and circuit board, for those skilled in the art, the structure of this traditional type electric connector is existing, and it comprises: be used for accommodating the insulating body of chip module, the plurality of conductive terminals that is installed on insulating body, frame and establish the following iron plate of insulating body, rotatablely be assembled in down on the iron plate and be covered in the last iron plate of chip module top and be assembled in down the driving lever that iron plate is used to be locked in iron plate.Electric connector of the present utility model is similar to existing electric connector, comprise: insulating body 3, conducting terminal, last iron plate, following iron plate and driving lever, except the detailed structure of conducting terminal slightly different, so only shown the schematic diagram of conducting terminal, the other parts of electric connector are no longer diagram or description just, and this point can't influence enforcement of the present utility model.

Please specifically consult Fig. 1 to shown in Figure 3, conducting terminal 1 is by the moulding of metal material integrated punching, and it comprises: be platy structure and be fixed on base portion 10 in the insulating body 3, on one side direction of base portion 10 upper ends, extend into the connecting portion 11 of terminal accommodation holes (not label), the docking section 110 that lateral margin from the bottom of connecting portion 11 is bent to form, connect this docking section 110 and upwardly extending elastic portion 12, cantilever 13 in the bending of elastic portion 12 levels, end from cantilever 13 extends the contact site 14 that is provided with hook, in the transition part 15 of the middle part of base portion 10 root edges bending and be positioned at the weld part 16 that transition part 15 bottoms are used to connect tin ball 2.Wherein, the upper end and the lower end that are positioned at the relative both side edges of base portion 11 are provided with some hangnails that protrude out relatively 101, and this hangnail 101 can be fixed in conducting terminal 1 in the corresponding terminal accommodation holes (not label) of the insulating body 3 of electric connector.

Please specifically consult Fig. 2 to shown in Figure 6, being positioned at same row with different view respectively is conducting terminal 1 on the same strip (not shown).The weld part 16 of conducting terminal 1 of the present utility model can have the mode of two kinds of bendings, and a kind of weld part 16 bends the place ahead that is positioned at base portion 11 forward from transition part 15, and another kind of weld part 16 bends the rear that is positioned at base portion 11 backward from transition part 15.The weld part 16 that is positioned at same row's conducting terminal 1 alternately is bent to form two row's weld parts 16 to the front side or the rear side of base portion 11 respectively.The weld part 16 that alternately is arranged in two row can be accommodated a fairly large number of conducting terminal 1 in insulating body 3 of the same area, the density of arranging of tin ball 2 also can increase, thereby effectively improves the density of arranging of conducting terminal 1.

Purport of the present utility model is that the weld part 16 of same row's conducting terminal 1 alternately is bent to form two row's weld parts 16 to the both sides, front and back of base portion 11 respectively, the density of arranging of conducting terminal 1 and tin ball 2 can be effectively increased, the trend that chip module (not shown) develops to highdensity direction can be guaranteed.
