The damage-preventing conductive terminal can be effectively protected when inserting and pulling out an electronic card.
Description
Technical field
The present invention relates to electric connector field, espespecially a kind of deck prevented routed type conducting terminal and use this conducting terminal.
Background technology
Ultra-thin, screen enlarging is the development trend of current smart mobile phone, and this also improves further to the requirement of mobile phone spare part, and size, thickness requirement are more and more less, causes mobile phone spare part to need Configuration design scheme to adapt to this trend.
Such as, SIM card holder traditional in mobile phone, owing to not requiring on thickness, the plastic cement of SIM card holder and conducting terminal generally adopt the assembling mode of spigot, namely plastic body arrange terminal groove, then are assembled into by conducting terminal in described terminal groove; And at present, all SIM card holder are substantially all required that height reduction is to below 1.5mm, adopt the mode of spigot cannot reach target, generally adopt the mode be integrally formed in described plastic body by described conducting terminal to reduce height.Although the program reduces the integral thickness of product, due to the elastic arm height reduction of conducting terminal, elastic space is not enough, likely causes when plugging SIM card, occurs that SIM card is wiped and hangs described conducting terminal elastic arm and make described elastic arm occur situation about damaging.
Summary of the invention
The object of the present invention is to provide and a kind ofly there is the conducting terminal of anti-structure of bursting and use the deck of this conducting terminal.
For this reason, the invention provides a kind of anti-type conducting terminal of bursting, the leg comprise base portion, extending to form from described base portion and the elastic contact arm extended to form that is inclined upwardly from described base portion one end, described elastic contact arm comprise contact top, from described contact top bending rear-inclined extend to form downwards against end, described conducting terminal also comprises the pre-pressure arm extended to form from described base portion, and described pre-pressure arm comprises the pre-splenium above end being positioned at described elastic contact arm.
Described pre-pressure arm extends in parallel formation with described elastic contact arm from described base portion homonymy, the extended end portion that described pre-pressure arm also comprises top ends, extends to form obliquely after described top ends bending, extends to form towards described against end obliquely from described extended end portion side during described pre-splenium.
Described pre-splenium rear end extends to form and is resisted against described precompressed end above end.
Guidance part is extended to form obliquely after described pre-splenium front end bending.
Described extended end portion forms from described top ends extension and forms stage portion between.
The horizontal level at the contact top of described elastic contact arm is higher than the horizontal level of the top ends of described pre-pressure arm, the horizontal level against end of described elastic contact arm is higher than the horizontal level of the extended end portion of described pre-pressure arm, and the horizontal level at the contact top of described elastic contact arm is higher than the horizontal level of the pre-splenium of described pre-pressure arm.
Described pre-pressure arm extends to form with described elastic contact arm subtend.
Described pre-pressure arm extends to form in vertical direction from described base portion and described elastic contact arm
For this reason, the invention provides a kind of deck using described anti-type conducting terminal of bursting.
Compared to prior art, the present invention's design anti-burst type conducting terminal by arrange a pre-pressure arm in order to elastic contact arm described in precompressed against end, realize when removable electronic card, prevent described elastic contact arm from being wiped the situation of hanging damage and occur.

Embodiment
The pre-pressure arm 13 of the leg 11 refer to shown in Fig. 1 to Fig. 3, conducting terminal of the present invention comprises base portion 10, extending to form from described base portion 10, the end of elastic contact arm 12 described in the elastic contact arm 12 that extends to form and the end precompressed that extends to form from described base portion 10 that to be inclined upwardly from described base portion 10 one end.
Described elastic contact arm 12 comprise be in horizontal peak contact top 121, from described contact top 121 end downward bending extend to form against end 122.
Described pre-pressure arm 13 extends in parallel formation with described elastic contact arm 12, the extended end portion 132 comprise top ends 131, tilting to extend to form from described top ends 131 end downward bending and upwards extend to form pre-splenium 133 towards described against direction, end 122 from described extended end portion 132 side.Described pre-splenium 133 extends back to be formed and is positioned at described precompressed end 134 above end 122, and described pre-splenium 133 front end bending has extended to form guidance part 135 downwards.Described extended end portion 132 has extended to form stage portion 136 from the bending of described top ends 131.
In its natural state, the horizontal level at the contact top 121 of described elastic contact arm 12 higher than the horizontal level of the top ends 131 of described pre-pressure arm 13, described elastic contact arm 12 against the horizontal level of end 122 higher than the horizontal level of the extended end portion 132 of described pre-pressure arm 13.The horizontal level at the contact top 121 of described elastic contact arm 12 is higher than the horizontal level of the pre-splenium 133 of described pre-pressure arm 13.
The anti-principle of bursting of described conducting terminal is: when SIM card is inserted from elastic contact arm 12 direction, because it inserts the contact top 121 can not damaging conducting terminal in the same way; When extracting SIM card, the contact top 121 of described conducting terminal against end 122 under the compacting of the precompressed end 134 of described pre-pressure arm 13, can not extension be wiped by described SIM card and cause inverse bending, and the guidance part 135 of described pre-splenium 133 front end is because horizontal level is lower and have the guiding gradient of inclination, make described SIM card oppositely can not damage described pre-pressure arm 13.So, anti-effect of bursting can be reached, namely prevent from the process of plug SIM card, damage described conducting terminal.
In other embodiments, described pre-pressure arm 13 can be pressed in advance after extending with described elastic contact arm 12 subtend described elastic contact arm 12 against end 122; Meanwhile, described pre-pressure arm 13 also can extend from the side of described elastic contact arm 12.
Refer to shown in Fig. 4, conducting terminal of the present invention is used for a kind of SIM card holder, the base portion 10 of described conducting terminal is integrally formed in described insulating body 20, described leg 11 extends outside described insulating body 20, described elastic contact arm 12, extends upwardly in a card receiving space 30 with described pre-pressure arm 13.
Conducting terminal of the present invention by arrange a pre-pressure arm 13 in order to elastic contact arm described in precompressed 12 against end 122, realize when removable electronic card, prevent described elastic contact arm 12 by wipe hang damage situation occur.
