[embodiment]
For ease of better understanding the purpose of this utility model, structure, feature and effect etc., now with embodiment the utility model electric connector and conducting terminal thereof are described further in conjunction with the accompanying drawings.
Please refer to Fig. 4, the utility model electric connector, it comprises a body 1, runs through most terminal containing slots 11 of described body 1 up and down, multi-conducting terminals 2 is accommodated and is fixed in the corresponding described terminal containing slot 11.
Please refer to Fig. 3, each described conducting terminal 2 comprises a base portion 21, two elastic arms 22, two extensions 23 and a weld part 24.
Two described elastic arms 22 extend upward formation from described base portion 21 both sides respectively, and the end of each described elastic arm 22 forms a contact site 221, two described contact sites 221 respectively and is provided with in pairs, and the side between two described contact sites 221 forms an insertion mouth.
Two described extensions 23, extend to form downwards from described base portion 21 both sides respectively, each described extension 23 has one first relative side 231 and one second side 232, outwards protrude out a projection 233 from the position of described second side 232, described projection 233 and described terminal containing slot 11 interference engagement, and the height of described projection 233 is less than the height of the described projection 233 of being positioned at of described extension 23 with top.
Described weld part 24 is extended downward vertically by described base portion 21 and forms, and between two described extensions 23, the end of described weld part 24 is provided with one and thrusts end 241, and described weld part 24 and two described extension 23 coplanes.
In other embodiments, also can be like this:
Please refer to Fig. 5 and Fig. 6, described weld part 24 further comprises one first end 242 that extends from described base portion 21 downwards, bend a link 243 that extends from described first end 242 to direction away from described base portion 21, and from one second end 244 of described link 243 to the direction bending extension of close described base portion 21, described link 243 is used to connect described first end 242 and described second end 244, make described link 243 camber shapes, it is towards described direction bending of inserting mouthful, and is equipped with one downwards in the bottom 245 of described second end 244 of described weld part 24 and thrusts end 241.
During operation, please refer to Fig. 4, at first, described conducting terminal 2 is accommodated in the described terminal containing slot 11 that is fixed in described body 1 correspondence, described conducting terminal 2 is by being provided with described projection 233 and described terminal containing slot 11 interference engagement at described extension 23 away from a side of described weld part 24, make described conducting terminal 2 be fixed in the described terminal containing slot 11, the described projection 233 that is positioned at of described extension 23 is a loose fit with the structure and the described terminal containing slot 11 on top, the structure that whole described conducting terminal 2 and described body 1 are fixed has only the interference of these two described projections 233, and described weld part 24 is between two described extensions 23.
Secondly, on circuit board 3, coat scolder 4, the described weld part 24 of described conducting terminal 2 is welded on the described circuit board 3 by described scolder 4, in order to electrically connect described electric connector and described circuit board 3.After described weld part 24 welds with the described scolder 4 on the described circuit board 3, because the influence that described body 1 is expanded with heat and contract with cold, promptly can produce one to the described projection 233 of the described extension 23 of described conducting terminal 2 involves power, because described conducting terminal 2 is not anchored in the described terminal containing slot 11 completely, so when described conducting terminal 2 generations are mobile, the described power of involving on the two described projections 233 at first is passed to described extension 23, because the height of described projection 233 is less than the height of the described projection 233 of being positioned at of described extension 23 with top, being the described projection 233 of being positioned at of described extension 23 can reduce or cushion the described power of involving with the structure on top, and because described projection 233 interferes the area that contacts less with described body 1, so the described power of involving of the described projection of 1 pair of described body 233 itself is also less, length one timing when described extension 23, because the length of described projection 233 is shorter, relative described extension 23 to be positioned at described projection 233 just longer with the length on top, and the described power of involving is to conduct to described weld part 24 by the described projection 233 of being positioned at of described extension 23 with the structure on top, again because the path of the described power of involving transmission is longer, therefore when the described power of involving passes to described weld part 24, the described power of involving that arrives described weld part 24 is also just more little, because the described power of involving has obtained reducing and cushioning, thereby can effectively reduce the displacement of the described relatively circuit board 3 of described weld part 24 ends, reducing pullling of described weld part 24 and described scolder 4, thereby guarantee that excellent electrical property is connected between described electric connector and the described circuit board 3.
In sum, the utility model electric connector and conducting terminal thereof have following beneficial effect:
