Card connector

[technical field]

The utility model relates to a kind of card connector, relates in particular to a kind of sim card connector.

[background technology]

Continuous progress along with science and technology, improving constantly of people's daily life level, people are towards compact trend development to the volume requirement of various electronic equipments, small product size requires more little, also can require more and more littler to the part that it used, especially the daily mobile phone appearance and modeling of using is especially with the frivolous little demand that is, thus the sim card connector structure of its inner use must cooperate outward appearance demand and towards frivolous structural design.

The sim card connector of prior art is announced shown in No. 2552184 as Chinese utility model patent, it comprises insulating body and is shaped in the interior conducting terminal of insulating body that described conducting terminal comprises the contact site that contacts with SIM card that is immobilizated in the holding parts in the insulating body and extends to form from holding parts; The contact site of the corresponding conducting terminal of insulating body is formed with peristome, is pushed and downward strain by card when SIM card contacts with the conducting terminal contact site.

But, the conducting terminal contact site of existing card connector is to extend the tabular of shape from fixed part one end, so the elastic edge shape ability of contact site is relatively poor, so card face contact portion and need bigger pressing force when making its downward strain, its fixed part will inevitably be subjected to a moment loading and insulating body is produced active force upwards simultaneously, so the insulating body of existing card connector is to avoid the destroyed thickness that needs corresponding increase insulating body.So, the development trend that is unfavorable for the frivolous structure of card connector.

Therefore, necessary existing card connector is improved to overcome the shortcoming of prior art.

[utility model content]

The purpose of this utility model is to provide a kind of card connector, and its conducting terminal contact site has better elastic deformability.

For reaching above-mentioned purpose, the utility model provides a kind of card connector, and it comprises insulating body and is row is located at plurality of conductive terminals in the insulating body, described insulating body comprise body and run through body and form be the peristome that row are provided with; Described conducting terminal comprises that the fixed part that is fixed in the insulating body reaches the contact site in the cantilever that fixed part one end extends to form is arranged at described insulating body peristome; Described contact site comprises respectively two adjutages that be arranged in parallel from the extension of fixed part both sides, connect the linking arm of two adjutage ends and from the elastic arm of linking arm diagonally extending between two adjutages.

Compared to prior art, card connector of the present utility model has following beneficial effect: described contact site cantilever is arranged in the peristome of insulating body, and it comprises two adjutages and is located at elastic arm between two adjutages, has increased the elastic deformability of contact site by this.

[embodiment]

Below, will introduce the embodiment of the utility model card connector 1 in conjunction with Fig. 1 to Fig. 3 in detail.Card connector 1 of the present utility model comprises insulating body 2 and is shaped in conducting terminal in the insulating body 2, wherein insulating body 2 comprise plate-like body portion 20 and connect body 20 and form be the peristome 22 that two row are provided with.

Described conducting terminal is formed by the sheet metal punching press, and it comprises the first row terminal 3 and the secondary series terminal 4 that is two row settings, and the described first row terminal 3 is provided with at interval with secondary series terminal 4; The first row terminal 3 comprises first holding parts 30 that is immobilizated in the insulating body 2, extend first weld part 32 insulating body 2 outside from first holding parts, 30 1 ends reaches first contact site 34 in first holding parts, 30 other ends lie along the peristome 22 of insulating body 2.

Described first contact site 34 is frame shaped, it comprises that two adjutages that be arranged in parallel 340, the connection two adjutages 340 terminal linking arms 342 that are oppositely arranged with first holding parts 30 that extend to form from first holding parts, 30 both sides respectively reach the elastic arms 344 that form towards first holding parts, 30 direction diagonally extendings from linking arm 342 middle parts, and this elastic arm 344 is between described two adjutages 340; These first contact site, 34 cantilevers are arranged in the peristome 22, and wherein two adjutages 340 and linking arm 342 are positioned at peristome 22, and the elastic arm 344 that touches with clamping upwards protrudes out and is positioned at insulating body 2 peristomes 22 tops.Described two adjutages 340 extend upward from first holding parts 30 inclination earlier and are tilted to down extension again, and then are formed with fulcrum 346 respectively at contact point 36 correspondence positions with elastic arm 344.

Described secondary series terminal 4 comprises second fixed part 40 that is fixed in the insulating body 2, extends second weld part 42 insulating body 2 outside and be positioned at second contact site 44 of insulating body 2 peristomes 22 from the formation of second fixed part, 40 other end diagonally extendings from second fixed part, 40 1 ends, and this second contact site 44 upwards protrudes out and is positioned at insulating body 2 peristomes 22 tops.The

weld part

32,42 of described first row terminal 3 and secondary series terminal 4 protrudes out insulating body 2 both sides, back before respectively.Weld part about 32,42 setting of staggering on the card plug direction, first contact site 34 and second contact site are located along the same line, first fixed part 30 is fixed in the body 20 of peristome 22 1 sides of accommodating second terminal 4, and second fixed part 40 is fixed in the body 20 of peristome 22 1 sides of accommodating the first terminal 3.

Card connector 1 and card (not shown) when contacting, the contact point 36 of the first row terminal, 3 elastic arms 344 is touched by clamping to be pushed, and then make elastic arm 344 downward strain in insulating body peristome 22, when card inserts fully, the conducting strip and the 36 corresponding contacts of elastic arm 344 contact points of card, simultaneously the part of conducting strip both sides respectively with the fulcrum 346 corresponding butts of adjutage 340, elastic arm 344 is excessively downward to be out of shape to reduce, and then guarantees to maintain in the thickness range of insulating body 2 in the regime of elastic deformation of insulating body 2 than elastic arm 344 under the thin situation.

Because of elastic arm 344 cantilevers of the first row terminal 3 are arranged at the elastic deformability who has increased by the first row terminal 3 between two adjutages 340, only need less pressing force can make conducting terminal produce strain when card inserts and then contact with card is stable.Because of the elastic deformability of conducting terminal contact site increases, the pressing force of its distortion is reduced, so the thickness of insulating body 2 can correspondingly reduce, be beneficial to the frivolous development trend of card connector 1.

Certainly, the conducting terminal of the utility model card connector can all be designed to the first row terminal, 3 shapes, to obtain better effect.
