Embodiment
Aforementioned and other technology contents, feature and effect for the present invention, in the following detailed description coordinated with reference to a preferred embodiment of accompanying drawing, can clearly present.
Consult Fig. 1 to Fig. 3, a preferred embodiment of arrangements of electric connection of the present invention comprises the electric connector 2 that a circuit board 1 and is arranged at this circuit board 1.This electric connector 2 comprises an insulating body 3 and multiple terminal 4.
Insulating body 3 extends in longitudinal along a length direction L, and have perpendicular on front side of one of this length direction L 31, on front side of one in contrast to this 31 rear side 32, and multiple terminal-mounting grooves 33.31 edges of boards 11 protruding out this circuit board 1 on front side of this.Multiple terminal-mounting grooves 33 along the both sides of parallel this length direction L be respectively two rows recessed in this insulating body 2, and the terminal-mounting grooves 33 being positioned at both sides arranges symmetrically.Each terminal-mounting grooves 33 has groove our department 331 and a socket 332, and this socket 332 is extended toward two opposite sides from this groove our department 331 along this length direction L.
Consult Fig. 2 to Fig. 4, multiple terminal 4 respectively corresponding multiple terminal-mounting grooves 33 is arranged and the terminal 4 being positioned at both sides is symmetrical arranged in mirror image.Fig. 5 to Fig. 7 is consulted in another cooperation, and each terminal 4 comprises fixed part 41, pin portion 42, bend 43, elastic arm 44 and a contact site 45.This fixed part 41 has multiple convex thorn 411 protruded by two opposite sides and along a second direction II respectively.At the present embodiment, respectively there is a convex thorn 411 both sides of fixed part 41, and in addition, at the present embodiment, this second direction II is parallel with this length direction L, that is this second direction II and this length direction L is same direction.This fixed part 41 is fixed in this corresponding terminal-mounting grooves 33, is placed in socket 332 (consulting Fig. 8) with being specially close-fitting, and two convex thorns 411 are interfered fixing with the inwall defining corresponding socket 332.This pin portion 42 is extended at a first direction I of horizontal plane by the edge, side of this fixed part 41, and this first direction I is vertical with this length direction L, and namely this first direction I is also vertical with this second direction II.At the present embodiment, this pin portion 42 is tabular, is fixedly welded on this circuit board 1 in surface soldered mode.This bend 43 to be extended in contrast to the side in this pin portion 42 by this fixed part 41 and back-flexing makes its end towards this pin portion 42 beyond, and namely this bend 43 is roughly c-shaped bending.This bend 43 can the elastic force that resets to provide this elastic arm 44 of strain.This elastic arm 44 is tilted to extend towards the direction gradually away from this fixed part 41 by this bend 43 end, and this elastic arm 44 toward this on front side of 31 deflections and press from both sides the angle [alpha] 1 of an acute angle at the bearing of trend III of the projection of horizontal plane and length direction L (i.e. second direction II), and press from both sides the angle [alpha] 2 of an acute angle with this first direction I, that is angle [alpha] 1 and angle [alpha] 2 sum are length direction L (i.e. second direction II) and the angle of first direction I, are 90 degree.At the present embodiment, this angle [alpha] 1 is 45 degree, and this angle [alpha] 2 is also 45 degree.In addition, this elastic arm 44 has a ribs 441 of one extrusion molding, to strengthen the intensity of this elastic arm 44.This contact site 45 is extended by this elastic arm 44 end, and at the present embodiment, this contact site 45 is in dome-shaped.
Consult Fig. 1, Fig. 4, Fig. 6 and Fig. 8, at the present embodiment, the fixed part 41 of multiple terminal 4, pin portion 42, bend 43 are positioned on this circuit board 1, namely in the scope of circuit board 1.And in multiple terminal 4 near on front side of this 31 elastic arm 44 part of pair of terminal 4 protrude out these edges of boards 11 of this circuit board 1 and contact site 45 is positioned at outside these edges of boards 11.This insulating body 3 also has two stop sections 34, respectively corresponding be arranged in multiple terminal 4 near on front side of this 31 this to below the contact site 45 of terminal 4, with contact site 45 is stressed move down time block multiple contact site 45, avoid multiple contact site 45 excessively to move down.As shown in Figure 8, the present embodiment can be arranged in the shell (non-icon) of a device for mobile communication, and the edges of boards 11 of circuit board 1 near shell side and be spaced a distance, the electronic cards 8 for a such as SIM card is electrically connected.By the elastic arm of multiple terminal 4 44 toward this on front side of 31 deflections, related make multiple contact site 45 toward this on front side of 31 deflections and be positioned at outside these edges of boards 11 to the contact site 45 of terminal 4 near this of front side 31, the contact site 45 of terminal 4 and the distance of shell side can be shortened, that is, the length that electronic cards 8 needs to enter in shell can be shortened.In other words, shorten the distance with shell side due to the overall side deflection toward shell of multiple contact site 45, make the electronic cards 8 that length is shorter, such as mini SIM card, compact SIM card etc., the length stretched in shell can be reduced, be conducive to the plug operation of electronic cards 8.
Moreover, because the bend 43 of all terminals 4, fixed part 41 and pin portion 42 are all positioned at the scope of circuit board 1, when the contact site 45 of terminal 4 to contact with the contact pad 81 of electronic cards 8 formed be electrically connected time, the pressure of electronic cards 8 suffered by terminal 4 can be supported by circuit board 1 and insulating body 3, can guarantee the holding capacity of electric connector 2 and insulating body 3 can not be made to be positioned at the collapse of unsettled outside edges of boards 11 part split.In addition, in dome-shaped, the contact site 45 of terminal 4 guarantees that contact site 45 can contact with corresponding contact pad 81.
In sum, the structure of the present embodiment terminal 4 and the design of electric connector 2, a part for electric connector 2 can be made to protrude out the edges of boards 11 of circuit board 1, thus the contact site 45 of terminal 4 and the distance of shell side can be shortened, that is, the length that electronic cards 8 needs to enter in shell can be shortened, to facilitate installation or replacing electronic card 8.In addition, the bend 43 of all terminals 4, fixed part 41 and pin portion 42 are all positioned at the scope of circuit board 1, the pressure of electronic cards 8 suffered by terminal 4 can be supported by circuit board 1 and insulating body 3, can guarantee the holding capacity of electric connector 2 and insulating body 3 can not be made to be positioned at the collapse of unsettled outside edges of boards 11 part split.
But, the above, be only preferred embodiment of the present invention, when can not limit the scope of the claims in the present invention with this, i.e. all simple equivalence changes of doing according to the present patent application right and invention description content and amendment, all still belongs in scope that the claims in the present invention contain.
