Abstract
A SIM card connector includes an insulating body and a plurality of electric terminals. The insulating body has accepting holes and accepting cavities. The electric terminal has a welded slice, a contact and a fixing portion. The welded slice and the contact are accepted in the accepting hole, the contact projects from the accepting hole. A lump is formed in one side of the fixing portion, the fixing portion accepted in the accepting cavities. While the SIM card connector passes through a SMT apparatus, the insulated body is soften and the lump is against the side wall of the accepting cavities for preventing the holding portion out of the insulated body. Therefore, the SIM card connector is welded firmly in the PCB of a mobile.
Claims5
A SIM card connector used to connect a SIM card with an electric apparatus, comprising:
- an insulated body having an upper surface and a lower surface, accepting holes defined in the lower surface, accepting cavities formed through the upper surface and connected with the corresponding accepting holes, two accepting grooves respectively arranged along opposing sides of each of the accepting holes, each of the accepting grooves defining a first inner side surface and a second inner side surface opposite to the first inner side surface;
- and
- electric terminals, each disposed in one of the accepting holes and a corresponding one of the accepting cavities, each of the electric terminals having a first connected portion, one end of the first connected portion extending to form a welded slice, the other end of the first connected portion extending upward to form a bend portion, the free end of the bend portion extending to form a second connected portion approximately parallel with the first connected portion, a contact projecting from the free end of the second connected portion;
- wherein the first connected portion of each of the electric terminals extending to form two fixing portions at two sides thereof, each fixing portion having an extendable spring which connects the fixing portions with the first connected portion, a free end of the extendable spring extending upward to form a resisting portion with a first lateral side and a second lateral side opposite the first lateral side, a protrusive member formed on the first lateral side of each resisting portion, the second lateral side of each resisting portion having a ramp formed thereon, a top portion of each resisting portion being narrower than a bottom portion of each resisting portion, wherein the protrusive member projecting from the first lateral side of each resisting portion engaging the first inner side surface of a corresponding accepting groove;
- a surface above the ramp of the second lateral side of each resisting portion is disposed in spaced relation apart from the second inner side surface of the corresponding accepting groove;
- and a surface below the ramp contacting the second inner side surface of the respective accepting groove.
