Description
The relevant a kind of electric connector of the utility model especially refers to a kind of electric connector that is used to electrically connect chip base plate and circuit board.
Related art can be consulted United States Patent (USP) the 5th, 395, No. 252,5,324, No. 205,5,653, No. 600,4,553, No. 192 and the 5th, 820, cases such as 389, wherein typical existing structure as shown in Figure 6, electric connector 200 includes insulating body 70 and elastic conduction terminal 80, wherein insulating body 70 is provided with the accommodating area 72 that extends 76 of first side 74 and second sides, be provided with a draw-in groove 78 in the accommodating area 72, conducting terminal 80 is installed the wing 82 by it and is fixed in the draw-in groove 78, and conducting terminal 80 is provided with the inwall of two elastic arms 84 in order to butt accommodating area 72, the end of this elastic arm 84 is the contact jaw 86 that extends outside the insulating body 70, respectively is provided with contact chip 96 on chip base plate 92 and the circuit board 94.When chip base plate 92 and electric connector 200 were crimped on circuit board 94, contact chip 96 just contacted with contact jaw 86, is close to respectively on first side 74 and second side 76 until chip base plate 92 and circuit board 94.Yet existing electric connector 200 can only be reached the telecommunication conducting with contact jaw 86 butt contact chips 96 these a kind of modes, can not satisfy the needs of multiple juncture (as the surface adhesion mode).And its contact jaw 86 lays respectively at installs the wing 82 both sides, when this two contact jaw 86 offsets press contacts with chip base plate 92 and circuit board 94 respectively, the pressure that acts on this two contact jaw 86 can produce a rotating torque, and conducting terminal 80 is occurred around the trend that the wing 82 rotates is installed, and then it is loosening to cause terminal 80 to take place, so that influences its fixing effect and electrically transmission.
The purpose of this utility model is to provide a kind of can pass through the direct butt conducting of conducting terminal, can pass through surface adhesion technology or the combination of solder sphere mode again, energy dispersive stress, the electric connector that makes the terminal stress equalization and have good fixing effect.
The utility model purpose is reached like this, and this electric connector includes insulating body and some structures such as conducting terminal that are contained in the insulating body.Wherein insulating body is provided with some accommodating area, offers accepting hole and and the adjacent accepting groove of accepting hole in accommodating area.Conducting terminal is provided with the U-shaped hold-down arm, and it includes two connecting portions and weld part, extends base portion by connecting portion one end, and the other end then extends the support portion, and is provided with a contact arm between base portion and support portion, and the free end of contact arm is overlapped on the support portion.Again, chip base plate and insulating body be arranged in parallel, and the inner plane of chip base plate and circuit board can electrically connect with conducting terminal, and it is provided with contact chip corresponding to the set accepting hole of insulating body.When the chip base plate when pressing down, its contact chip compresses contact arm, make contact arm produce strain, its free end presses the support portion, be symmetrical arranged and all be installed on the insulating body because of support portion and base portion are substantially, so the suffered stress of contact arm will be dispersed in the two ends near support portion and base portion, and make the whole stress equalization of terminal, be unlikely and unbalance stress take place and loosening phenomenon.
By above structure, the utility model can pass through surface adhesion technology or the combination of solder sphere mode again by the direct butt conducting of weld part of conducting terminal, and with maintenance terminal stress equalization, thereby reach the purpose of this utility model.
Below by accompanying drawing and preferred embodiment the utility model is further described.
Fig. 1 is the three-dimensional combination figure that the utility model electric connector comprises chip base plate and circuit board.
Fig. 2 is the three-dimensional combination figure of the utility model electric connector.
Fig. 3 is the cutaway view that the utility model electric connector comprises chip base plate and circuit board.
Fig. 4 is the cutaway view that the utility model electric connector second embodiment comprises chip base plate and circuit board.
Fig. 5 is the cutaway view that the utility model electric connector the 3rd embodiment comprises chip base plate and circuit board.
Fig. 6 is the cutaway view that comprises chip base plate and circuit board of existing electric connector.
See also Figure 1 and Figure 2, the utility model electric connector 100 can be in order to electrically connecting chip base plate 30 and circuit board 40, and it includes insulating body 10 and is contained in structures such as plurality of conductive terminals 20 in the insulating body 10.
Insulating body 10 is provided with first surface 102 and reaches and first surface 102 opposing second surface 104, be concaved with some accommodating area 120 by first surface 102 to second surface 104 directions, in accommodating area 120, offer several accepting holes 122 and the accepting groove 124 adjacent with accepting hole 122 by first surface 102 to second surface 104 one.Conducting terminal 20 is provided with U-shaped hold-down arm 28, the weld part 284 that it includes two connecting portions 282 and engages two connecting portions 282, extend base portion 21 by connecting portion 282 1 ends, the other end then extends support portion 24, and 24 of base portion 21 and support portions are provided with a contact arm 26, and the free end 262 of contact arm 26 is overlapped on the support portion 24.Again, base portion 21 bends out interference part 22 vertically downward.
Please cooperate and consult Fig. 1 and Fig. 3, the interference part 22 of conducting terminal 20 is contained in the accepting groove 124 of insulating body 10,24 of base portion 21 and support portions are contained in the accommodating area 120 of insulating body 10, and support portion 24 is terminal and 10 of insulating bodies keep some slits to hold the strain of conducting terminal 20 slightly.Again, two connecting portions 282 are close to accepting hole 122 inboards, and 284 of weld parts stretch out outside the accepting hole 122.
See also Fig. 2 and shown in Figure 3, the contact chip 42 of circuit board 40 props up weld part 284, when chip base plate 30 when pressing down, its contact chip 32 compresses contact arm 26, contact arm 26 stressed backs produce strain, two component about its pressure can be decomposed into, wherein a component is that 21 directions shift and act on this base portion 21 places along contact arm 26 towards base portion, another component then acts on the support portion 24 through free end 262, because of support portion 24 and base portion 21 are plate body, and it is installed on the insulating body 10, so all morning insulating body 10 of pressure disperses.And, make conducting terminal 20 whole stress equalizations and can be not the basic point rotation with weld part 284 because pressure acts on the two ends, the left and right sides of conducting terminal 20 respectively.Again, the interference part 22 of conducting terminal 20 is immobilizated in the accepting groove 124, and weld part 284 is that two row are provided with, thereby guarantees the firm of conducting terminal 20.
See also shown in Figure 4, be second embodiment of the present utility model, its top in contact chip 42 is connected to a welding material 50, weld part 284 is soldered on the welding material 50 by the surface adhesion technology, when chip base plate 30 was depressed, the variation situation of its conducting terminal 20 was same as described above and reach the purpose of this utility model.See also shown in Figure 5, be the 3rd embodiment of the present utility model, be connected to a solder sphere 60 in the centre of two weld parts 284, pass through solder sphere 60 butts again to contact chip 42, when chip base plate 30 was depressed, the variation situation of its conducting terminal 20 was same as the previously described embodiments and reach the purpose of this utility model.
