Embodiment
Like Fig. 1～shown in Figure 5; The embodiment 1 of the power contact of the utility model; This power contact is installed in the power contact installation cavity of insulation shell of adaptive rectangular electric connector in use; And be connected with circuit board through its pin, this power contact 2 is made up of a pair of top, end contact chip 10,11, and end contact chip 11 wherein is in use more near circuit board.The structure of top, end contact chip is basic identical, at this apical grafting contact is described in detail.
Simultaneously the substrate of apical grafting contact 10 and the substrate of end contact chip 11 also have towards interior surface opposing with towards opposing outer surface, with the inner surface of substrate towards direction be defined as inwardly, with the outer surface of substrate towards direction be defined as outwardly.
Fingertip 21 has all that an end is connected with substrate 20 before each of apical grafting contact 10, the other end is towards the fin part 211 of tilt perk; The front end of fin part 211 has tilted plate section 214; This tilted plate section 214 is towards tilt; But tilted plate section 214 is less than the trend of tilted plate section 214 fin part 211 before towards tilt towards the trend of tilt; Being shown as tilted plate section 214 in the drawings has outwardly slope trend and has included angle B with respect to the fin part 211 before the tilted plate section 214; Make tilted plate section 214 diminish so in fact with respect to the degree of substrate 20 bottom surfaces towards tilt, thus the bottom surface of tilted plate section 214 power contact 2 contact with adaptive contact and can form during pressurized the convergence level, be beneficial to the plane that increases the conductive contact surfaces area.The front end of the tilted plate section 214 of fin part 211 is connected with the curved sheet part 212 that bends outwards perk; The bottom surface that the front end of curved sheet part 212 is connected with respect to substrate 20 belongs to the plane towards the oblique sheet part 213 of the bending of outer incline perk; But the trend that bends the perk outwardly of oblique sheet part 213 is less than the trend of curved sheet part 212 front ends perk outwardly; Thereby between the bottom surface of bottom surface that bends oblique sheet part 213 and curved sheet part 212, form the arc thrust concave surface 215 that caves inward, this arc thrust concave surface 215 cooperates with the thrust convex surface 321 identical blocks of the arc of the front beam 32 of said insulation shell 1.Tilted plate section 214 in this a kind of embodiment of the utility model is as the terminal extensions of fin part 211 and transition is connected between fin part 211 and the curved sheet part 212; Certainly in other execution modes of the utility model; If do not pursue best electro-contact effect, also tilted plate section 214 can be set and directly directly be connected with curved sheet part 212 with what fin part 211 did not bend.
The similar of contact chip of the said end 11 and apical grafting contact 10; Its difference is; End contact chip 11 is in order to adapt to the installation site of pressing close to circuit board in use and to abdicate the space that the pin that holds apical grafting contact 10 passes through on the whole; The length of the pin of end contact chip 11 is smaller than the length of the pin of apical grafting contact 10, and the length on the fore-and-aft direction of end contact chip 11 substrates is smaller than the length on the fore-and-aft direction of apical grafting contact 10 substrates.In addition; The preceding fingertip structure of top, end contact chip is identical in fact; But the perk direction of the perk direction of the preceding fingertip each several part on the end contact chip and said apical grafting contact 10 each several parts is for being symmetrical set up and down, under user mode, forms the female contact piece structure that supplies adaptive public contact to insert between the two with folded plane symmetry with the structure that guarantees top, end contact chip.Further; In order under the short situation of the substrate length of end contact chip 11, to keep the positioning stablity of its location alar part; The location alar part front end of the substrate both sides of end contact chip 11 also one is connected with two location tongue pieces 111 that extend forward, be shorter than preceding fingertip; Certainly in other embodiment of the utility model, the location tongue piece 111 that also can not be provided with.
The foregoing description is the less small size power contact of a kind of size, and in other embodiment of the utility model, top, the preceding fingertip of end contact chip and the number of pin can be more than three; Like Fig. 7, shown in Figure 8; The embodiment 2 of the power contact of the utility model is a kind of large size power contact, and its preceding fingertip has 6; Pin is 3, and is provided with two place's lock slots between each pin.
Like Fig. 1～shown in Figure 12; The embodiment of the rectangular electric connector of the utility model; Comprise the insulation shell 1 of rectangle and the power contact of wherein installing, insulation shell 1 front end be the inserted terminal of corresponding graftings with intermateable connector, when insulation shell 1 has installation near and reach towards the bottom surface of adapter circuit plate and the end face of circuit board installation site furthest; The both sides of the length direction of insulation shell 1 are the left and right sides, and insulation shell 1 surface is provided with ventilation guiding gutter 9.Be provided with a plurality of length directions power contact installation cavity that distribute, that be used to assemble the power contact in the insulation shell 1 at insulation shell 1; In the present embodiment; The power contact of adorning be divided into like Fig. 6, large size power contact 5 shown in Figure 7 with like Fig. 1～small size power contact 2 shown in Figure 5 by its size; Therefore according to the size of adaptive contact; Power contact installation cavity is divided into large size power contact installation cavity 6 and 3 two kinds of small size power contact installation cavitys; Both similar, here mainly with the embodiment of above-mentioned power contact in the small size power contact 2 introduced adaptive small size power contact installation cavity 3 be that example is introduced.In addition, also be provided with the signal contacting piece installation cavity 8 that signal contacting piece 7 is installed in the insulation shell 1, the be placed in left and right sides of signal contacting piece installation cavity 8 of large size power contact installation cavity 6 and small size power contact installation cavity 3.
