Embodiment
Below will combine accompanying drawing, specific embodiments of the invention and embodiment specify, and described specific embodiment in order to explain the present invention, is not to be used to limit embodiment of the present invention only.
A kind of multiple-contact connectors of the present invention; Bridge-type sim card connector to be welded on the cell phone mainboard is an example; As shown in Figure 1, comprise the deck 100 that insulating material such as adopting bakelite, plastics are made and adopt the shell fragment 200 of metallic conduction material such as copper alloy such as beryllium copper or phosphor-copper even stainless steel; As shown in Figure 2, main parts such as the head 220 that shell fragment 200 is connected by one and afterbody 230 are formed; Afterbody 230 is fastened on the deck 100; On deck 100, also be provided with the vestibule 110 that width and length all surpass head 220; So that but the head 220 of shell fragment 200 fits in compressive deformation in the vestibule 110, the vestibule 110 on the promptly said deck 100 provides the displacement space of its head 220 compressive deformations for shell fragment 200 wherein; Wherein, shell fragment 200 is provided with 220 open slots 210 to afterbody 230 extensions from the head, and head 220 is divided into a main stress contact 221 and one stress contact 222; Perhaps, shell fragment is provided with two or more open slot that extends to afterbody from the head, and head part is slit into a main stress contact and two or more stress contacts.Said stress contact can play the effect of compensation and conducting to the main stress contact, reduces to occur easily the probability of momentary interruption, improves the reliability with the SIM conducting.
In preferred implementation of the present invention; The width of said stress contact root can be equal to the width of main stress contact root; When shell fragment contacts with SIM, have identical contact force thus, also be superior to single contact scheme of the prior art, but be not optimal case; Be preferably; As shown in Figure 2, the width of said main stress contact 221 roots is obviously greater than the width of inferior stress contact 222 roots, thus when shell fragment contacts with SIM; Said main stress contact 221 and root thereof can be born bigger contact force; Playing main conducting effect, said stress contact 222 and root thereof are then born less contact force, to play the effect of compensation conducting.
Being provided with two or more open slot that extends to afterbody from the head for shell fragment forms for two or more stress contacts; A kind of situation is; The width of a plurality of stress contact roots is identical, but its width is significantly less than the width of main stress contact root; Each time stress contact can play the compensation conducting effect of same degree to the main stress contact thus, with the contact reliability of further raising connector.
Another kind of situation is; In a plurality of stress contacts; The inferior stress contact root width far away from the main stress contact is less than the inferior stress contact root width nearer from the main stress contact; In other words, near more inferior stress contact root width is wide more from the main stress contact, thus each time stress contact compensation conducting effect degree that the main stress contact is played difference slightly all; Compensation conducting effect from the near more inferior stress contact in main stress contact plays is obvious more, thereby also can further improve the contact reliability of connector.
Concrete; No matter whether the width of time stress contact root is identical with the width of main stress contact root; Also no matter whether the width between time stress contact root is identical, in above each embodiment, said stress contact both can be arranged on the both sides of main stress contact; Perhaps, also can be arranged on the same side of main stress contact.
Be preferably, the width of said shell fragment afterbody is greater than the width of its head, and afterbody is main stressed place; The afterbody of wider width has played the effect of reinforcement and reinforcement to its head thus, thereby makes head have stronger elastic force, has also increased the Elastic Contact power of main stress contact with time stress contact; Concrete, as shown in Figure 2, can adopt the form of step transition between the narrower head 220 of the afterbody 230 of wider width and width, also can adopt the form of hypotenuse transition.
In addition, only for the head 220 of said shell fragment, also can adopt the reinforcement design of hypotenuse transition or step transition form at the root of head 220; Specifically refer to, as shown in Figure 2, can pass through the hypotenuse transition between main stress contact and its root, also can pass through step transition; And, can pass through the hypotenuse transition between inferior stress contact and its root, also can pass through step transition.
Concrete, as shown in Figure 2, said open slot 210 can be set to the straight-line groove of vertical shell fragment 200 Widths, also can be set to the curved groove that extends to afterbody from the head; For two or more open slot, but parallel interval setting between many open slots, and the width of every open slot can identically be provided with.
Further, as shown in Figure 3, on the afterbody 230 of said shell fragment, also be extended with the welding pin 240 that exceeds deck 100 edges; For example, said welding pin 240 can be used for the SIM connector is welded on the cell phone mainboard.
Based on above-mentioned multiple-contact connectors, the invention allows for a kind of sim card connector, as shown in Figure 1, this sim card connector comprises that one is used for the deck 100 of bridge-type buckle SIM and the shell fragment 200 of six metals; The sim card connector that also has eight shell fragments in addition is an example with the sim card connector of six shell fragments only here; In conjunction with shown in Figure 2, each shell fragment 200 all comprises the head 220 and afterbody 230 that one connects; Afterbody 220 is fixed on the deck 100, and it is corresponding one by one with six shell fragments 200 also to be respectively arranged with six vestibules 110 on the deck 100; But the head 220 of each shell fragment 200 lays respectively at compressive deformation in vestibule 110 separately, and in other words, the vestibule 110 on the said deck 100 is respectively the displacement space that wherein shell fragment 200 provides its head 220 compressive deformations; Wherein, on each shell fragment 200, all be provided with 220 open slots 210 from the head at least, head 220 is divided into a main stress contact 221 and at least one time stress contact 222 to afterbody 230 extensions.
With regard to the bridge-type sim card connector, as shown in Figure 3, all shell fragments all can be provided with along the plug sim card direction; And head 220 exceeds the main stress contact and time stress contact of deck 100 contact-making surfaces 120 relatively; The root that is connected with the afterbody one on the head 220 preferably is arranged on plug-in card entrance point one side of deck 100; Can avoid thus when plug sim card, cause extruding even fracture exceeding deck 100 contact-making surfaces 120 too high heads 220.
Compare with sim card connector of the prior art; A kind of multiple-contact connectors provided by the present invention and sim card connector; Owing on metal clips, adopted open slot, single contact is divided into a main stress contact and at least one time stress contact, each metal clips is all with two contacts or the contacted mode in plural a plurality of contacts thus; With respect in the past only with the contacted mode in single contact; Contact inferior stress contact in the mode of two contacts or a plurality of contact has played the effect of compensation and conducting when connecting, greatly reduce the probability that occurs momentary interruption easily, has obviously improved the reliability that connector contacts.
Should be understood that; The above is merely preferred embodiment of the present invention, is not sufficient to limit technical scheme of the present invention, concerning those of ordinary skills; Within spirit of the present invention and principle; Can increase and decrease according to above-mentioned explanation, replacement, conversion or improvement, and all these increases and decreases, replacement, conversion or improve after technical scheme, all should belong to the protection range of accompanying claims of the present invention.
