Description
[technical field]
The utility model is a kind of zero inserting force electric connector, refers to a kind of zero inserting force electric connector that is used to electrically connect CPU and circuit board especially.
[background technology]
Existing zero inserting force electric connector comprises: pedestal, cover plate and the driving lever of accommodating terminal.Its cover plate is the impetus slippage on pedestal that can borrow driving lever, move with the pin that drives CPU, provide between pin and terminal electrically to contact, therefore, the slippage of cover plate on pedestal is steadily comparatively crucial to the resistance to overturning that improves zero inserting force electric connector.
Existing zero inserting force electric connector as shown in Figure 7 and Figure 8, this zero inserting force electric connector 8 comprises pedestal 80, cover plate 81 and a driven unit 83.Wherein pedestal 80 is provided with first interface 801 and first hook part 802, and cover plate 81 is provided with second hook part 811.The impetus of borrowing driven unit 83 when cover plate 81 during slippage, is borrowed first hook part 802 and second hook part 811 to fasten mutually to guarantee that cover plate 81 is stablized and is covered on the pedestal 80 on first interface 801 of pedestal 80.But, because the card contact-making surface 800 that colludes after first hook part 802 engages with second hook part 811 is mutual is that first interface 801 with pedestal 80 is parallel to each other, therefore, when cover plate 81 was subjected to improper external force, second hook part 811 on the cover plate 81 easily deformed and breaks away from first hook part 802.In order to prevent that first hook part 802 and second hook part 811 from the bad phenomenon that breaks away from taking place, 811 dorsal parts are provided with a metal catch 84 in second hook part, thereby limit second hook part, 811 outside strains.Yet this metal catch 84 needs other to come stamped by the die sinking tool, thereby causes number of parts to increase and make manufacturing cost be difficult to reduce, and efficiency of assembling also is difficult to promote.
Another prior art such as United States Patent (USP) the 5th, 722, No. 848, see also Fig. 9 and Figure 10, the socket connector 3 that the prior art disclosed is provided with pedestal 30, and lid is connected on the pedestal 30 and can and be provided with the driven unit 34 of joystick 341 with respect to the lid 32 of pedestal 30 slippages.Pedestal 30 1 ends are provided with groove 301, be provided with the holding section 302 of the tool restriction face 3021 of projection in this groove 301, respective slot 301 positions are provided with the fastening assembly 323 to pedestal 30 extended tool " L " tee sections on the lid 32, and it comprises to pedestal 30 directions are extended and aligns portion 3231 and to hook part 3232 that lid 32 protrudes out.When the joystick 341 of driven unit 34 is in vertical shape, when promptly this socket connector 3 is in opening, the interference that contacts with the restriction face 3021 of the holding section 302 of pedestal 30 of the some of hook part 3232, but easily cause hook part 3232 and holding section 302 to throw off because the contact area of hook part 3232 and holding section 302 is too small, thereby can not guarantee stable electric connection between zero-force connector for socket 3 and the plant CPU (not icon) on it.
[summary of the invention]
The purpose of this utility model is to provide a zero inserting force electric connector, and it can provide the overall structure stability of zero inserting force electric connector, also can effectively reduce manufacturing cost simultaneously.
The purpose of this utility model is achieved in that provides a kind of zero inserting force electric connector, and it comprises pedestal, cover plate and the driving lever of accommodating plurality of terminals.Wherein pedestal is provided with square first interface and a two through hole, and is provided with first hook part in each through hole.Cover plate can be borrowed impetus slippage on pedestal first interface of driving lever, which is provided with second interface, vertically extends integrated connecting portion in the lead to the hole site of the corresponding pedestal of second interface, and the end of connecting portion is provided with second hook part.The buckle contact-making surface and first interface that this second hook part and first hook part can fasten mutually are angled, and the contact area of this first hook part and second hook part is constant when the relative pedestal slippage of cover plate.
Compared with prior art, the utlity model has following advantage: the buckle contact-making surface and first interface that second hook part of zero inserting force electric connector and first hook part can fasten mutually are angled, and the contact area of this first hook part and second hook part is constant when the relative pedestal slippage of cover plate, thereby provides the overall structure of zero inserting force electric connector stable.

[embodiment]
See also shown in Figure 1ly, the utility model zero inserting force electric connector 1 comprises that the pedestal 10 of accommodating plurality of terminals 11, lid are connected on the pedestal 10 and can be with respect to cover plate 12, driving lever 13 and the engaging support mechanism 14 of pedestal 10 slippages.
Wherein pedestal 10 is provided with first interface 101, and integrated protuberance 102.Wherein offer on first interface 101 be arranged plurality of terminals hole 103 to be used to accommodate terminal 11, pedestal 10 is near establishing a side of protuberance 102 and being provided with the arc groove 104 of accommodating driving lever 13 along cover plate 12 directions of motion, and these arc groove 104 both sides are provided with through hole 105.
See also Fig. 2, shown in Figure 3, engaging support mechanism 14 (as shown in Figure 5) comprises one-body molded second hook part 142 of extending connecting portion 124 ends on first hook part 141 of being located at arc groove 104 both sides and second interface 122.Wherein first contact-making surface 1411 of first hook part 141 is obliquely installed at an angle in pedestal 10 first interfaces 101.Second contact-making surface 1421 of second hook part 142 also is obliquely installed at an angle with cover plate 12 second interfaces 122, and this angle equates with first interface, 101 angulations with first contact-making surface 1411.
See also Fig. 4, shown in Figure 5 again, cover plate 12 is in buckling state with pedestal 10.Wherein the hole 105 of pedestal 10 is run through in second hook part 142 of engaging support mechanism 14 through suitable strain, and be fastened on first hook part 141, thereby pedestal 10 is fastened on cover plate 12, and colludes card contact-making surface 143 in 142 formation one in first hook part 141 and second hook part.Driving lever 13 is contained in the arc groove 104 of pedestal 10, and borrow second interface 122 of cover plate 12 to be located in the arc groove 104 of pedestal 10, and driving lever 13 can rotate in the arc groove 104 of pedestal 10, borrow the cam of being located on the driving lever 13 1321 to force on the sheet metal 15 that is installed in cover plate 12 grooves 123 (as shown in Figure 6), and then promote cover plate 12 slippage on first interface 101 of pedestal 10.Since first hook part 141 of engaging support mechanism 14 and second hook part 142 collude card contact-making surface 143 and pedestal 10 first interfaces 101 angled, and this area that colludes card contact-making surface 143 is constant during slippage on 10 in cover plate 12 in pedestal, thereby effectively prevents the first interface 101 come-up dynamic deformations of cover plate 12 from pedestal 10.
