[utility model content]

The technical problems to be solved in the utility model is to provide a kind of stable electric connector that is immobilizated in insulating body of conducting terminal that allows.

For addressing the above problem, the utility model is by the following technical solutions: a kind of electric connector, it comprises insulating body and conducting terminal, this insulating body is frame shape structure, it is provided with an end face, insulating body is concaved with accepting groove downwards from end face, to accommodate aforementioned conducting terminal, conducting terminal comprises the elastic arm that the main part that is fixed in the accepting groove and diagonally extending go out accepting groove, main part comprises two side arms that are provided with relatively and connects the linking arm of two side arms, side arm is provided with the clamping part of clamping cable, and described linking arm is provided with the holding part that interlocks and hold with insulating body.

Compared with prior art, the utlity model has following beneficial effect: the holding part of setting up on the conducting terminal linking arm can guarantee the stable insulating body that is immobilizated in of conducting terminal.

[embodiment]

Ginseng Fig. 1, electric connector 100 of the present utility model comprises insulating body 1 and a pair of conducting terminal 2 that is assembled in insulating body 1.

Ginseng Fig. 2, insulating body 1 rectangular frame shape structure, its center position is a rectangle accepting hole 11, this accepting hole 11 is enclosed by the short edge of the long frame edge of two symmetries and two symmetries and forms.Insulating body 1 is concaved with two U type accepting grooves 12 of accommodating described conducting terminal 2 downwards from upper surface 101, and each accepting groove 12 comprises the side channel 121 of being located at described two long frame edges and is located at described short edge and connects the link slot 122 of this two side channel 121.The short edge at link slot 122 places outwards convexes with the protuberance 16 that a pair of interval is provided with from outside wall surface, is concaved with button on the protuberance 16 and holds groove 160.Two side channels 121 of same long frame edge separate by a dividing plate 13, and each side channel 121 is provided with the holding slot 14 of the lateral surface that runs through insulating body 1 long frame edge downwards and the groove 15 of contiguous dividing plate 13, and this groove 15 runs through the diapire of long frame edge downwards.

Ginseng Fig. 2, conducting terminal 2 is by a sheet metal punching press bending forming, and it comprises the main part 21 of U type, the end of this main part 21 elastic arm 22 of the upper surface 101 that extends insulating body 1 that is inclined upwardly certainly.Main part 21 comprises two side arms that are oppositely arranged 211 and is connected in the linking arm 212 of two side arms 211 ends that elastic arm 22 is to be inclined upwardly from these two side arms 211 free ends to extend to form.Linking arm 212 has been bent to form holding part 25 downwards and towards the direction near linking arm 212 again from lateral border elder generation horizontal-extending.The lateral border at side arm 211 middle parts is provided with the holding parts 23 that extends downward vertically, and side arm 211 medial margins are provided with the clamping part 24 that extends into accepting hole 11.Clamping part 24 is in order to clamping cable (not shown), this clamping part 24 comprises first holding piece 241 and second holding piece 242, wherein first holding piece 241 extend horizontally away from described side arm 211, second holding piece 242 is positioned at the below of first holding piece 241, and and first holding piece 241 between be an acute angle.Elastic arm 22 is with main part 21 corresponding U types and is positioned at the top of main part 21, it comprises the contact arm 222 that is connected and is two adjutages 221 of acute angle setting with described two side arms 211 and be connected in two adjutages, 221 ends, and these contact arm 222 middle parts are provided with the contact site 223 that contacts with a circuit board (not shown).
