Abstract
The utility model discloses an electric connector which has the advantages of high density and good electric performance, comprising an isolation body provided with a plurality of containing grooves and a plurality of conductive terminals contained and arranged in the containing grooves. The conductive terminals are provided with a main body part whose both ends are extended with two elastic arms. The end of the two elastic arms are both bended with an arc-shaped contacting part and the width of the containing grooves are shorter than the horizontal extension distance of the elastic arms of the conductive terminals. Compared with the prior art, the utility model is characterized in that the contacting part of the conductive terminals of the electric connector so that the contact area between the electric connector and the circuit plate are larger. The utility model has the advantages of decreasing contact impedance and good electric performance, and the width of the containing grooves can be shorter than the horizontal extension distance of the elastic arms of the conductive terminals to reach a compact arrangment.
Description
[technical field]
The utility model relates to a kind of electric connector, refers to a kind of electric connector that planar lattice array chip module and printed circuit board (PCB) are electrically connected of being used for especially.
[background technology]
At present, industry generally removes to electrically connect the planar lattice array chip module to circuit board with electric connector, and wherein electric connector generally comprises electric connector terminal.Prior art can be with reference to United States Patent (USP) the 6th, 488, and No. 513, this patent has disclosed the electric connector terminal of a kind of high density arrangement and the compressible contact in two ends.This electric connector terminal roughly is " C " shape and comprises two elastic arms and a main part up and down, wherein, elastic arm all extends at the two ends up and down of autonomous body up and down, and following elastic arm roughly is " an one " font that tilts, and its end can compress mutually with the metal gasket on the circuit board and contact.
Yet the defective of the prior art is: the surface area that the following elastic arm of electric connector terminal contacts with circuit board is less, only is the some contact, and therefore, insulation impedance is bigger, and electric property is relatively poor.And this terminal is fixing unreliable, may cause terminal to come off from insulating body.
Therefore, be necessary to design a kind of novel electric connector, to overcome above-mentioned defective.
[summary of the invention]
The purpose of this utility model is to provide the electric connector of a kind of terminal arranging density height and good electric property.
In order to reach above-mentioned creation purpose, the utility model electric connector, comprise the insulating body and the some conducting terminals that is located in the accepting groove that are provided with some accepting grooves, conducting terminal is provided with main part, this main part two ends extension is provided with two elastic arms, it is characterized in that: this two elastic arms end all bends and is provided with circular-arc contact site, and the width of accepting groove can be less than the horizontal-extending distance of terminal elastic arm.
Compared with prior art, the conducting terminal contact site of the utility model electric connector is circular-arc, thereby bigger with the contact area of circuit board, can reduce contact impedance, improves electric property; And the width of accepting groove can be less than the horizontal-extending distance of terminal elastic arm, can be comparatively tight thereby arrange.

[embodiment]
Below in conjunction with drawings and Examples the utility model is further described.
Please refer to Fig. 1 to shown in Figure 6, the utility model electric connector is used for electrically connecting planar lattice array chip module (figure does not draw) and circuit board (not drawing among the figure), wherein be equipped with some pads (not drawing among the figure) on chip module and the circuit board, this electric connector comprises conducting terminal 1 and insulating body 2, conducting terminal 1 is provided with main part 10, autonomous body 10 two ends make progress respectively, extend respectively downwards and be provided with first elastic arm 11 and second elastic arm 12, and first elastic arm 11 and second elastic arm, 12 ends all bend and are provided with circular-arc contact site 110,120.One epitaxial lateral overgrowth of autonomous body 10 is stretched and is provided with connecting portion 13, the terminal fixed part 14 that is provided with main part 10 almost parallels that extends of this connecting portion.These fixed part 14 1 sides are provided with depressed part 140, and these connecting portion two ends can be connected with strip.
Insulating body 2 is provided with some accepting grooves 20 to accommodate terminal respectively.The cell wall of accepting groove 20 is provided with the projection 21 corresponding with depressed part 140, and this projection 21 can be fixed on terminal in the insulating body 2 with depressed part 140 mutual buckles.
During assembling, the conducting terminal 1 (as shown in Figure 1) that at first will not bend second elastic arm inserts in the accepting groove 20 of insulating body 2, projection 21 on accepting groove 20 walls snaps in the depressed part 140 of fixed part 14 of conducting terminal 1, thereby conducting terminal 1 is retained in the insulating body 2.And then second elastic arm 12 of bending conducting terminal 1, promptly form the utility model connector terminals (as shown in Figure 2), like this, the width of accepting groove can be less than the horizontal-extending distance of terminal elastic arm, because of the not influence of the sub-elastic arm horizontal-extending of receiving end distance of accepting groove width, so can make terminal arrange comparatively closely.
Claims (3)
