Figure 1 shows that a kind of be used to relevant with the utility model electrically connect wafer module (not shown) to the electric connector 1 of printed circuit board (PCB) (not shown) ', it comprise insulating body 2 ', be contained in the plurality of conductive terminals 6 of insulating body 2 ' interior ', frame be located at the reinforced sheet 3 of insulating body 2 ' periphery ', be articulated in reinforced sheet 3 ' one ends be used to compress the pressing plate 5 of wafer module ' and be articulated in the other end of reinforced sheet 3 ' relatively be used to pin pressing plate 5 ' driving lever 4 '.Convex with on insulating body 2 ' peripheral sidewall interference rib 23 ', reinforced sheet 3 ' be the hollow casing structure, the middle part of its bottom surface be provided with the resettlement section 31 of hollow out ', 31 ' on every side are provided with four opposed inside walls (not label) in the resettlement section.During assembling, interference rib 23 ' pass through interference engagement with four opposed inside walls of resettlement section 31 ' on every side, with insulating body 2 ' be connected to reinforced sheet 3 ', then with pressing plate 5 ' and driving lever 4 ' be mounted on reinforced sheet 3 ' on, use securing member (not shown) with reinforced sheet 3 ' and insulating body 2 ' further be positioned on the circuit board thereafter, at last the wafer module is connected to electric connector 1 ' in.
Because insulating body 2 ' and the interference rib 23 that is connected with reinforced sheet 3 ' madial wall ' be integral type, so interfering edge is bigger, to insulating body 2 ' and finished product warpage influence is also bigger, and the plastics that produce when both cooperate bits easily drop insulating body 2 ' conducting terminal 6 ' on, cause electric connector 1 ' poor electrical contact.
Given this, be necessary to provide a kind of improved electric connector in fact, to overcome the defective of above-mentioned electric connector.
[summary of the invention]
The technical problem that the utility model solved provides a kind of less and prevent the plastics chip from dropping on the conducting terminal of insulating body and cause the electric connector of poor electrical contact to product warpage influence.
For solving the problems of the technologies described above, the utility model relates to a kind of electric connector, be used to electrically connect the wafer module to printed circuit board (PCB), it comprises insulating body, be contained in the reinforced sheet that plurality of conductive terminals in the insulating body and frame are located at the insulating body periphery, wherein, the insulating body peripheral sidewall convexes with the plurality of elastic trip, and each elastic clamping hook is provided with the bottom that cooperates with the reinforced sheet madial wall, this bottom is made up of some interference rib, and interference rib has the gap each other.
Compare with correlation technique, the utlity model has following advantage: owing to be concaved with some interference rib on the elastic clamping hook, so the plastics chip that produces when insulating body cooperates with reinforced sheet can be housed in the gap between the interference rib, and is difficult for dropping on the insulating body, causes foreign substance pollution; Simultaneously, also because the interference area of insulating body and reinforced sheet is less, so its corresponding interfering edge also can be less, thus less to the influence of insulating body warpage.

[embodiment]
See also Fig. 2 to shown in Figure 6, the utility model electric connector 1, be used to electrically connect wafer module (not shown) and printed circuit board (PCB) (not shown), the reinforced sheet 3 that it comprises insulating body 2, be contained in the plurality of conductive terminals of insulating body 2 (not shown), frame is located at insulating body 2 peripheries, and be articulated in locked instrument (not label) on the reinforced sheet 3, this locked instrument comprises pressing plate 5 and driving lever 4, and electric connector 1 is realized the electric connection of wafer module and circuit board by the instrumentality of conducting terminal.
Insulating body 2 rectangular tabular structures, it is provided with first lateral border 21 facing each other and second lateral border 22.Above-mentioned lateral border is enclosed to form in order to the conduction region of ccontaining wafer module (not label), is provided with the terminal containing slot (not shown) of some ccontaining conducting terminals in the conduction region.Wherein, the place, two ends of first and second lateral border 21,22 convexes with plurality of elastic trip 23, each elastic clamping hook 23 is the offset setting, the elastic clamping hook 23 that is the offset setting is made up of high portion 231 and bottom 232, wherein (not label) formed by some interference rib in bottom 232, to cooperate with reinforced sheet 3, this interference rib has the gap each other, is used to carry the plastics chip.The lateral surface of described high portion 231 is higher than the lateral surface of bottom 232, so form a cascaded surface 233 between the two, when insulating body 2 cooperated with reinforced sheet 3, this cascaded surface 233 was connected on the reinforced sheet 3.The high portion 231 of this elastic clamping hook 23 and 232 two ends, bottom are made as inclined-plane (not label) respectively.
Reinforced sheet 3 is made by the higher material of intensity.Reinforced sheet 3 is the hollow casing structure, and the middle part of its bottom surface is provided with the resettlement section 31 of hollow out, 31 carriers 33 that are provided with four opposed inside walls 32 on every side and extended by madial wall 32 in the resettlement section.The lateral margin of reinforced sheet 3 carriers 33 vertically extends a relative sidewall, and wherein to be articulated with the sidewall of driving lever 4 be the first side wall 331 to reinforced sheet 3, and relative with the first side wall 331 is second sidewall 332.The first side wall 331 roughly becomes " U " type, and it vertically extends earlier, roughly prolongs horizontal direction then again to reinforced sheet 3 inboard extensions.Second sidewall 332 of reinforced sheet 3 is provided with button and holds mouth 34, and a side of carrier 33 also upwards extends the tight lock part 35 of an arcuation.
Continue to consult Fig. 5 to shown in Figure 6, during assembling, can earlier reinforced sheet 3 be installed on insulating body 2 around, this moment, four opposed inside walls 32 of reinforced sheet 3 resettlement sections 31 were snapped on some interference rib 232 of elastic clamping hooks 23 at 2 four jiaos of places of insulating body.Owing to be concaved with some interference rib 232 on the elastic clamping hook 23, so the plastics chip that produces when insulating body 2 cooperates with reinforced sheet 3 can be housed in the gap between the interference rib 232, and be difficult for dropping on the insulating body 2, cause the conducting terminal poor electrical contact; Simultaneously, also because insulating body 2 is less with the interference area of reinforced sheet 3, its corresponding interfering edge also reduces thereupon, thereby reduces the influence of excessive interfering edge to insulating body 2 or finished product warpage.Again pressing plate 5 and driving lever 4 are mounted on the reinforced sheet 3, use securing member (not shown) further to be positioned reinforced sheet 3 and insulating body 2 on the circuit board then, above-mentioned securing member can be bolt etc., thereafter insulating body 2 is welded on the circuit board by conducting terminal, the wafer module of packing at last, rotary pressure plate 5 is held on the wafer module, the clamping part 54 of pressing plate 5 is connected to the surface of wafer module, the rocking bar 42 of rotation driving lever 4 makes press section 43 be connected to the auxiliary section 520 of pressing plate 5 and applies certain pressure in this auxiliary section 520, the wafer module also pushes so that the conducting terminal of wafer module and insulating body 2 conduction regions is realized firm the electric connection in the portion of holding 54 that adds of pressing plate 5 simultaneously, and the rocking bar 42 of driving lever 4 is positioned the tight lock part 35 of reinforced sheet 3 at last by Access Division 41.Like this, the wafer module firmly is connected in the electric connector 1.
