Description

Electric connector

Technical field

The utility model provides a kind of electric connector, refers to that especially a kind of conducting terminal mounting direction that changes is shortened welding foot length to promote the electric connector of whole yield.

Background technology

Employed signal coffret between LCD (LCD) and the system host board is the differential signal receiver in low voltage (LVDS that adopts tool ultrahigh speed, low-power consumption and low electromagnetic characteristic at present; Low Voltage DifferentialSignaling) be the signal coffret; This kind LVDS connector is to be used to provide the male end connector to peg graft.

The LVDS connector of generally commonly using is the insulating body with an elongated, the upper and lower wall of this insulating body tool, two side and rear wall, these walls surround a grafting space jointly, and upper and lower two walls of this insulating body respectively are provided with the terminal slots of plural equi-spaced apart, the terminal slots of this upper wall surface is assembled with plural earth terminal, the terminal slots of this lower wall surface is assembled with conducting terminal, coats one at last again in the insulating body outside and covers shell to intercept the interference of external electromagnetic ripple.When this electric connector is installed on the system host board when using for the male end connector, be to link in the mode that level lies low, follow-up because of the demand in the product specification variation, the former mode of connection that becomes with vertical stand-up of establishing of inciting somebody to action is welded on the system host board, thus, this conducting terminal is the antetheca that is installed in insulating body, and be existing circuit arrangement following that does not change circuit board, the welding foot that is about to this conducting terminal is oppositely bent by the antetheca of insulating body and extends the rear wall of its length to this insulating body, it is difficult to cause conducting terminal to make because of welding foot is long, reach and assemble upward or the puzzlement on the degree of keeping, fraction defective promotes greatly, material or cost of labor are also high, are not inconsistent economic benefit in fact.

Summary of the invention

The purpose of this utility model is that a kind of electric connector is being provided, and it can effectively shorten the welding foot length of conducting terminal and reach the electric connector of identical effect.

For achieving the above object, electric connector of the present utility model is characterized in that comprising: insulating body is constituted a longitudinal and opening accommodation space up by diapire, antetheca, rear wall and two side; The complex conduction terminal is the rear wall that is installed in this insulating body, and it comprises the conduction terminal that extends into accommodation space and extends the outer welding ends of insulating body rear wall; Ground strip is the antetheca that from bottom to top is installed in this insulating body, and it is provided with plural shell fragment and extends in this accommodation space relatively with the conduction terminal of aforementioned conducting terminal, reaches shielding casing, is for the one bending forming and from bottom to top is coated on the outside of insulating body.

Compare with conventional art and the utlity model has following beneficial effect: comprise insulating body, conducting terminal, ground strip and shielding casing, this insulating body tool diapire and surrounding wall, and surround an accommodation space and accommodate this conducting terminal and this ground strip, wherein, this conducting terminal is to be the rear wall that the L type is installed in this insulating body accommodation space, the one end forms and to protrude in accommodation space and use and dock the contacted conduction terminal of male end bonder terminal, end then vertically bends the rear wall that extends this insulating body in addition, and this ground strip is the antetheca that is installed in insulating body, this shielding casing is the outside that is coated on insulating body, so, the conduction terminal of this conducting terminal and welding ends all are positioned at the rear wall of this insulating body, avoid to elongate welding foot, also can reach the identical effect of this electric connector for the circuit arrangement that cooperates circuit board.

Embodiment

See also Fig. 1, Fig. 2, electric connector of the present utility model comprise insulating body 1, snap-latch piece 2, ground strip 3, shielding casing 4 and conducting terminal 5, wherein:

Insulating body 1 is to be plastic material, have diapire 11, antetheca 12, rear wall 13, two side 14 and lengthwise type opening accommodation space 15 up, the front and

back walls

12,13 of this insulating body 1 all is provided with plural number and equidistantly is separated by and runs through the first terminal slot 16 of this diapire 11 and second terminal slots 17 in accommodation space 15, this diapire 11 is near these rear wall 13 places, be provided with the fixing slot 18 of equi-spaced apart, reach two side 14 slot 19 that is run through by diapire 11 is set, the forward and

backward wall

12,13 of this insulating body 1 further is provided with plural combination slot 20;
