Description

Electric connector

The utility model is a kind of electric connector, relate in particular to a kind of conducting terminal good, that stablize conduction property that has, and both can effectively locate the terminal of different length, good retain strength and bed hedgehopping effect can be provided again, and make electric connector can be applicable to that the electronic installation of specific standard reaches the electric connector under the bigger stressing conditions.

Electronic installation can be provided with some peripheral equipments usually to support and to cooperate its normal operation; with the computer is example; assemble many inside and peripheral element through the electric connector switching; as disc driver, CD drive, printer and display etc.; for the main circuit board of above-mentioned electronic installation, the signal transmission quantity is bigger between it and main circuit board, can be at the back independent startup of connecting with the mains; therefore, the utilization transmission speed is fast, the simple electric connector of docking mechanism is necessary.Be relevant to electric connector of the present utility model design and please refer to United States Patent (USP) the 5th, 586,915,5,577, cases such as No. the 85202087th, No. 936 and TaiWan, China patent application have all disclosed electric connector structure as shown in Figure 5.This electric connector 5 mainly is provided with insulating body 50, one side of this insulating body 50 is provided with interface frame, mating frame 51, this interface frame, mating frame 51 to inside be concaved with for the butt joint usefulness slotted eye, and this slotted eye from inside to outside one convex with plate face 511 with ccontaining conducting terminal 52 on the side surface of this plate face 511.Conducting terminal 52 1 ends are placed in the terminal hole of plate face 511 sides to be connected with group with butt connector, and the other end then extends to a relative side of electric connector 5, and are engaged on the circuit board after suitably bending in insulating body 50.In addition, insulating body 50 is engaged in the side of circuit board and the appropriate position group is provided with at least two fasteners 53, electric connector 5 temporarily can be stayed on circuit board in order to welding by this two fastener 53.Though above-mentioned electric connector can connect as the aforementioned electronic installation equipment and electric connection is provided, yet, because the general flexible terminal of not strengthening of this electric connector utilization is with the conducting that achieves a butt joint, contact conducting strength after the butt joint relies on terminal to provide fully, therefore, under the situation of the bending scarce capacity that terminal can provide,, make telecommunication conducting situation instability with making electric connector terminal can't firmly dock bigger electronic component and the peripheral equipment of weight that it docked.Moreover this type electric connector is not generally all considered suitable bed hedgehopping, so it highly usually is difficult to the electronic installation equipment that cooperates whole height higher, as hard disk, CD-ROM drive etc.In addition; the weight of above-mentioned various electronic equipments is big; therefore regular meeting brings sizable moment to electric connector when pegging graft; the moment of particularly working as the plug connector elements winding of electric connector and this electronic equipment; electric connector will be that fulcrum rotates backward with the another side root edge in contrast to interface; terminal fixing after having only the dependence fastener this moment and welding avoids electric connector to topple over to produce bracing force.Yet this mode will influence the welding steadiness of connector terminals weld, damages the electric conductivity of itself and main circuit board easily.

The utility model electric connector purpose is to provide a kind of electric connector good, that stablize the conducting terminal of contact performance that has, it can guarantee to engage facility and the telecommunication transmission is stable, and can connect taller and bigger, heavy electronic component, and can not topple over because of moment of flexure is excessive.

The technical scheme of the utility model electric connector is, connector terminals has default stress and elasticity-intensified structure, and the elasticity that can provide can be provided, and makes it when docking electronic component and peg graft, has more suitable effective clamping ability, to increase the reliability of contact; This electric connector positioner is made as a layer stepwise, the layer stepwise positioner of this holding plate can cooperate longer terminal and increase its fixing localization part, make the terminal of different length reduce the chance of being out of shape, so that the spacing of terminal abutting end keeps stable and easily engages with circuit board, this electric connector bed hedgehopping portion side offers storage tank, and the screw rod that can directly insert the tool nut in it is with electric connector and circuit board is affixed is integral.

By such scheme, the utility model electric connector contact performance is stable, and can guarantee to engage stability convenient and electrical transmission, and can connect taller and bigger, heavy electronic component, can not topple over because of moment of flexure is excessive.
