Description

Electric connector

[technical field]

The relevant a kind of electric connector of the present invention, finger has the electric connector of conducting terminal holding structure especially.

[background technology]

The conducting terminal of existing array electric connector need be immobilizated in the insulating body, prevents that conducting terminal from sliding when connecting.As shown in Figure 5, depressed part is set on conducting terminal usually, during assembling insulating body is snapped in the depressed part of conducting terminal, realize the fixing of conducting terminal in vertical direction.But in this fixing mode, because depressed part is a position that mainly is subjected to insulating body to hold power, and the depressed part width is less than other position, concentrates so easily produce stress around the depressed part, and terminal suffers damage easily.

In addition, as disclosed conducting terminal in No. 200620073583.1 patent of China, conducting terminal second connecting portion is not subjected to the spacing of horizontal direction, when the conducting terminal compressive deformation, conducting terminal has along the possibility of vertical axis rotation, so can't guarantee the normotopia degree of conducting terminal; And this conducting terminal is higher in the dense degree of second accepting groove, and the rotation of conducting terminal can cause touching mutually between terminal, and then causes short circuit.

Therefore, be necessary to provide a kind of electric connector with novel conductive terminal holding structure.

[summary of the invention]

Main purpose of the present invention provides a kind of novel conductive terminal holding structure that has, the electric connector that can avoid conducting terminal stress to concentrate.

For reaching above-mentioned purpose, the invention provides a kind of electric connector, comprise conducting terminal, limiting plate, stop catch plate and substrate; Conducting terminal is provided with base portion, and base portion both sides bending respectively extend to form arm, and the bearing of trend of two arms is identical, two arms be parallel to each other and length identical, arm is provided with upper surface and the lower surface that is parallel to each other; Limiting plate is provided with the accepting hole that can accommodate the conducting terminal arm; Stop catch plate is located at the limiting plate top, and has through hole to pass through for conducting terminal; Substrate is positioned at limiting plate below, and arm is connected to substrate, but wherein stop catch plate relative limit plate slippage, and then be covered in the arm of conducting terminal.

Compared to prior art, electric connector of the present invention has following effect: the slippage stop catch plate so that with the substrate acting in conjunction in the conducting terminal arm to realize spacing to conducting terminal, can avoid conducting terminal to be provided with depressed part, and then avoid the stress of conducting terminal to concentrate.

[embodiment]

See also shown in Figure 1ly, electric connector 100 comprises conducting terminal 11, adaptation board 12, stop catch plate 13, limiting plate 14 and substrate 15.Conducting terminal 11 passes adaptation board 12, stop catch plate 13, limiting plate 14 and substrate 15 from top to bottom.

See also shown in Figure 2, conducting terminal about in the of 11 two ends be respectively equipped with can with dock first, second contact site 111,112 that electronic building brick (not shown) electrically connects, from first contact site, the 111 downward locking portions 113 that extend, be bent downwardly the elastic portion 114 of extension from locking portion 113, the base portion 115 that own elasticity portion 114 extends downwards, from the interference part 118 that base portion 115 extends and conducting terminal 11 interference can be immobilizated in substrate 15 downwards, interference part 118 extends to form second contact site 112 downwards.The width of whole base portion about in the of 115 is identical, its both sides bending respectively extend to form 119, two arms 119 of arm and are positioned at base portion 115 phase the same sides, have upper surface 116, lower surface 120, connect the end face 117 on upper and lower surface, two arms 119 are parallel to each other, and length is identical.Arm 119 roughly becomes U-shaped with base portion 115.

See also shown in Figure 1ly, adaptation board 12 is provided with mating hole 121, and the locking portion 113 of conducting terminal 11 is contained in the mating hole 121.The elastic portion 114 of conducting terminal 11 is longer, when conducting terminal 11 cooperates with the butt joint electronic building brick, locking portion 113 is subjected to the restriction of mating hole 121, its first contact site 111 and locking portion 113 only can move up and down along mating hole 121, so locking portion 113 can prevent that first contact site 111 of conducting terminal 11 from cooperating hour offset with the butt joint electronic building brick.

See also Fig. 2 and shown in Figure 4, stop catch plate 13 is located at limiting plate 14 tops, and has the through hole 131 of rectangularity roughly to pass through for conducting terminals 11, and electric connector 100 assembling back stop catch plate 13 lower surfaces can contact with the upper surface 116 of conducting terminal 11 arms 119.

Limiting plate 14 is provided with the accepting hole 141 that rectangularity roughly can be accommodated conducting terminal 11 arms 119.The height of the limiting plate 14 roughly height with conducting terminal 11 arms 119 is identical.

Substrate 15, its circular holding hole 151 that is provided with the array arrangement is to cooperate with the interference part 118 of conducting terminal 11.The upper surface of holding hole 151 positions of arm 119 lower surfaces 120 butt substrates 15, the length of conducting terminal 11 arms 119 prevent that greater than the width of the holding hole 151 of its contact position conducting terminal 11 is to bottom offset.

See also Fig. 1 to shown in Figure 4, the accepting hole 141 of limiting plate 14 and the through hole 131 of stop catch plate 13 are corresponding one by one.When limiting plate 14 and stop catch plate 13 not during relative displacement, the lap of its accepting hole 141 and through hole 131 is higher, and the lap width can allow conducting terminal 11 to pass through greater than the length of conducting terminal 11 arms 119; After conducting terminal 11 was mounted to the precalculated position, mobile stop catch plate 13 was covered in the upper surface 116 of conducting terminal 11 arms 119 with the lower surface of stop catch plate 13, prevents that conducting terminal 11 is to top offset; After stop catch plate 13 moves, the inwall of its through hole 131 is posted by the one side of conducting terminal 11 base portions 115, the opposed inner walls of the below accepting hole 141 corresponding with this through hole 131 is posted by the another side of conducting terminal 11 base portions 115, then the inwall of stop catch plate 13 through holes 131 is seized conducting terminal 11 on both sides by the arms with the inwall of its corresponding limiting plate 14 accepting holes 141 in below from the two sides, guarantee the normotopia degree of conducting terminal 11, prevent that promptly conducting terminal 11 from rotating around vertical axis.
