Embodiment
Describe the present invention below with reference to execution mode shown in the drawings.But this execution mode does not limit the present invention, the structure that those of ordinary skill in the art makes according to these execution modes, method or conversion functionally are all included in protection scope of the present invention.Described " height ", " low ", " on ", D score position relationship is all using the description that the loading end of described insulating body does as level reference upwards; Described "front", "rear" relation with described elastic arm bearing of trend for reference to the description done.
Be illustrated in figure 1 the structural representation of card connector 100 of the present invention, comprise insulating body 1 and be fixed on some conducting terminal 2(in insulating body 1 as shown in Figure 5).Described insulating body 1 has the loading end 11 carrying electronic cards.The elastic arm 22 that conducting terminal 2 described in each comprises the fixed part 21 be fixed in described insulating body 1, extend to form from described fixed part 21 and leg 23.
Referring to Fig. 2-7, described elastic arm 22 has the linking arm 221 be connected with described fixed part 21, the contact arm 222 oppositely extended to form from the end of described linking arm 221 and the connecting portion 223 connecting described contact arm and linking arm, described contact arm 222 is disposed adjacent with described linking arm 221, the two ends of described contact arm 222 are not all arranged higher than described loading end 11, in the middle part of described contact arm 222 near the side of described connecting portion 223 upwards projection be formed higher than described loading end 11 in order to the contact site 2221 docking terminal and connect, at its bearing of trend, in " S " type, complications extend described linking arm 221.
Particularly, described elastic arm 22 comprises two the described linking arms 221 being symmetricly set in described contact arm 222 both sides, described contact arm 222 is set to two parts in punishing fork near described connecting portion 223, and is connected to two described linking arms 221 respectively by described connecting portion 223.Described contact arm 222 and linking arm 221 are also formed with the first consistent guidance part 224 of incline direction in the one end near described connecting portion 223, and described first guidance part 224 extends downward the below of described loading end 11.Described connecting portion 223 belongs to a part for the first guidance part 224.Described first guidance part 224 is roughly rendered as two symmetrical " U " types.End and described connecting portion 223 place of described first guidance part 224 are also formed with movable part 225, and inevitably, described movable part 225 is lower than described loading end 11.
On the projection direction of described contact site 2221, described linking arm 221 is not higher than described contact site 2221.Described linking arm 221 height rises and falls and the support portion 2211 be formed on the projection direction of described contact site 2221 lower than described contact site 2221.Described contact arm 222 is also formed with away from the side of described connecting portion 223 the second guidance part 2222 tilting to extend.The free powder end of described second guidance part 2222 is also bent to form the sliding part 2223 in cambered surface.
Described card connector 100 comprises and is fixed on insulating body 1 and the three groups of conducting terminals 1 arranged along the grafting direction of described card connector 100, and the bearing of trend of the elastic arm 22 of described conducting terminal 2 is completely the same.Described insulating body 1 is roughly rectangular, and the position of the elastic arm 22 of corresponding described conducting terminal 2 offers the mounting groove 12 of the rectangle run through up and down.Fixed part 21 and described mounting groove 12 size of described conducting terminal 2 match.
Card connector 100 of the present invention is when with electronic cards grafting, because the end of described first guidance part 224 is arranged lower than described loading end 11, electronic cards can not touch the end of conducting terminal 2, and the contact site 2221 that described electronic cards continues forward slip and then compresses described contact arm 222 under the guiding of described first guidance part 224 completes electric connection.Described contact site 2221 is subject to downward extruding force can there is strain, described contact arm 222 is by the two Slideslips extensions forwards, backwards of movable part 225, sliding part 2223, and then electronic cards touches support portion 2211, the downward power that compresses suffered by contact arm 222 is shared by described support portion 2211 and being born.
The three-dimensional structure diagram of the card connector 200 of another execution mode of the present invention as shown in Figure 8, described card connector 200 comprises insulating body 1 ' and fixing and insulating body 1 ' and three groups of conducting terminals (non-overview diagram) of arranging successively along the grafting direction of card connector described in it 200, and described conducting terminal has fixed part 21 ' different from the conducting terminal 2 of described card connector 100.Often organize conducting terminal and comprise symmetrical pair of conductive terminal, the elastic arm 22 of described symmetrical pair of conductive terminal is extended in Eight characters symmetry.Insulating body 1 structure of described insulating body 1 ' and described card connector 100 is inconsistent, and described insulating body 1 ' has the installed surface vertical with the bearing of trend of described elastic arm 22, roughly indentation arrangement on the grafting direction of described card connector 200.
Be illustrated in figure 9 card connector 200 in Fig. 8 and be assembled to the structural representation of circuit board 300.The upper surface that described leg 23 is soldered to described circuit board 300 completes electric connection.
In said process, first avoid elastic arm 22 and collided crowded collapsing by electronic cards, structure is more stable, effectively improves the useful life of card connector 100,200 of the present invention.On the other hand, avoid to a certain extent contact arm 222 because of compressing of electronic cards excessive deformation, effectively ensure that good electric connection effect.
