[concrete Implementation Modes]
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
See also Fig. 2 and Fig. 3, the utility model electric connector 1 is used for chip module (not icon) is electrically connected to circuit board 13, comprising: insulating body 10 and be located in terminal 11 in the insulating body.
See also Fig. 4, insulating body 10 is provided with base portion 101 and vertically extends the baffle plate 102 that parallel height equates in base portion 101 one sides, it between the baffle plate 102 elongated slot 103, base portion 101 is provided with the accepting hole 104 of dip-parallel, described accepting hole 104 communicates with elongated slot 103 bottoms, and the aspect ratio of accepting hole 104 and insulating body 10 is 2:5.The base portion 101 of insulating body 10 is provided with the spacer portion 1010 of dip-parallel, and 1010 outer one ends of spacer portion are provided with inclined-plane 10100, and bigger accommodation space 1011 is arranged between the inclined-plane of adjacent spaces portion 1010.
See also Fig. 5 and Fig. 7, conducting terminal 11 is a tabular, two relative platen surface are arranged on it, it is (not shown to be respectively first platen surface 114 and second platen surface, i.e. 114 the back side), two platen surface two opposite sides are by being connected with second side 117 by first side 116 respectively, conducting terminal has holding parts 112, correspondence is fixed in the terminal accommodation holes 104, holding parts 112 has extended downwards and printed circuit board (PCB) 13 contacted first contact sites 110, has upwards extended and contacted second contact site 113 of chip module (not icon).First contact site 110 is provided with elastic portion 111 near an end of holding parts 112, this elastic portion 111 is extended along first side, 116 directions by first platen surface 114 and second platen surface 115, and be " C " shape, the width of this elastic portion 111 is less than the width of upper end holding parts 112.Second contact site, 113 tops are provided with chamfering 1131.
Wherein, accepting hole 104 is 2:5 with the aspect ratio of insulating body 10, can guarantee the elasticity of second contact site so effectively.The effect of baffle plate 102 is to prevent that terminal from tilting to side, when chip module is pressed on the terminal, can prevent that chip module from pressing low and cause the flexural deformation of terminal and the contact of terminal before and after causing.Accepting hole 104 oblique arrangement make also oblique arrangement of terminal 11, and when chip module was pressed on the terminal, terminal had reasonable elasticity.Spacer portion 1010 outer ends are provided with inclined-plane 10100, and the installation that is beneficial to conducting terminal that is provided with on this inclined-plane 10100 imports.First contact site 110 is welded on the circuit board 13 by tin ball (not icon), to realize the electric connection of electric connector and circuit board 13.In addition, terminal 11 also can adopt its first contact site 110 to compress the method that contacts mutually with chip module (not icon) and circuit board 13 respectively with second contact site 113, realizes the electric connection of chip module and circuit board.Accommodation space 1011 can ccontaining conducting terminal 11 the part of elastic portion 111, thereby can reduce the volume of whole electric connector.
Wherein elastic portion 111 is extended with along side surface direction by platen surface and is beneficial to being processed to form of terminal.Elastic portion 111 makes the elasticity of terminal increase, and alleviates the downward propagation of contact force by the strain of terminal, thereby protects leg, reduces the generation of solder crack phenomenon.The elastic portion 111 of terminal is " C " shape can be concentrated by less stress, thereby can prevent effectively that terminal from being fractureed.The width of the elastic portion 111 of terminal is less than the width of upper end holding parts 112, to obtain better elasticity.Second contact site, 113 tops are provided with chamfering 1131, make terminal and chip module that bigger contact area be arranged, and can make contact stabilization like this, and help reducing electrical resistance.Terminal become tabular can so that terminal take up space little, dense arrangement more.
So; by implementing the utility model technological means; make that the cost of electric connector is lower; terminal takes up space little, and be fit to electric connector and develop to the densification direction, and; this electric connector conducting terminal has reasonable elasticity; can alleviate the downward propagation of contact force, thereby the protection leg reduces the generation of solder crack phenomenon.
