Description

The terminal structure of smart card connector

Technical field

The utility model relates to a kind of terminal structure of memory card connector, relates in particular to a kind of terminal structure that the plural weld part of terminal group can be extended the smart card connector of arranging towards homonymy.

Background technology

Current computer technology fast development especially aspect the light little and high-performance exploitation of notebook computer, makes desktop computer or notebook computer extensively popularize industry-by-industry in society, at all levels.And the computer peripheral device in the face of emerging in an endless stream now correspondingly, has also been developed the connector that can be connected with the electronics IC-card (being commonly called as " smart card ") of credit card-sized.As shown in Figure 7 be the stereo appearance figure of existing smart card, its shape such as length and width, the thick rectangle electronic cards A that is respectively L, W, T, and be provided with the paired contact chip A1 of two row in the single side surface of this electronic cards.

Yet, as Fig. 8 and shown in Figure 9 be the smart card connector B that generally uses at present.Its housing B1 is provided with plug-in card space B 2, and be provided with perforate B3 and contact chip B4 in housing B1 bottom, the terminal structure of this connector is: the fixed part B42 among the contact chip B4 is solidificated on the housing B1 with forced, and extended lead division B41 in fixed part B42 one side, lead division B41 is located at circuit board with Type of Welding; Opposite side has extended contact arm B43, and contact arm B43 is provided with the contact site B44 that projects upwards, and extends the abutting part B45 on a plane again at contact site B44, is connected to the below, edge of bottom opening B3.Similarly, be provided with another in the relative side of housing B1 coplanar and organize reverse contact chip B4.When electronic cards A inserts in the plug-in card space B 2 of connector B, under the effect that guiding presses down, the contact site B44 of contact chip B4 will contact with the contact chip A1 of electronic cards A.But, exist to be difficult for the defective that is connected with circuit board adapter in addition etc. because relatively each lead division B41 of two row contact chip B4 of configuration be dispersed the extension.

Again as shown in figure 10 be the vertical view of another smart card connector C commonly used.The terminal structure of this connector is: two groups of relative signal terminal set D, and signal terminal set D front end is provided with contact site D1, also be provided with one group of detecting terminal group E at side in addition, and the terminal supportor E1 front end of this terminal group E has extended abutting part E11 in vertical direction, and is provided with contact site E21 at the terminal supportor E2 front end parallel with terminal supportor E1.When electronic cards A inserts among the connector C, the contact site D1 of signal terminal set D contacts with the contact chip A1 of electronic cards A, and make the abutting part E11 of terminal supportor E1 front end of detecting terminal group E compress simultaneously downwards, contact with the contact site E21 of terminal supportor E2 and produce electric connection.But because signal terminal set D uses identical material, shape with detecting terminal group E, need to enable two groups of moulds and assembling respectively during fabrication, have the defective that material cost is higher, number of assembling steps is loaded down with trivial details.

Summary of the invention

In view of the deficiency and the defective of above-mentioned existing connector, the utility model provides a kind of plural weld part of terminal group can the extension towards homonymy to arrange and the convenient smart card connector terminal structure that connects external agency.

The purpose of this utility model is achieved through the following technical solutions:

A kind of terminal structure of smart card connector, this connector is made up of terminal group and insulating base frame, plural terminals adopts equidistant adjacent arrangement to concentrate its weld part, it is characterized in that: the terminal structure of this connector designs in the insulating base frame that contains in order to the hollow slots of taking in terminal group, wherein, the first terminal group has extended the contact elastic arm in each base portion one side, opposite side away from the contact elastic arm extends the weld part that is gradually-reducing shape, and be arranged at intervals with the weld part of second terminal group at each weld part adjacent of the first terminal group, and extended base portion thereon, be provided with first bending segment at the base portion opposite side again, and then at first bending segment toward extend the circle round portion of continuous bending away from the opposite side of base portion around contact elastic arm periphery, the structure of this portion of circling round is to be connected with one first parallel-segment by contact elastic arm one side with second bending segment, and be connected with the 3rd bending segment, and then utilize second parallel-segment to be connected with in first bending segment in the first parallel-segment opposite side.Said structure forms the equidistant adjacent arrangement of plural weld part and concentrates on the same side, made things convenient for itself and the connection of different external agencys, and then reached the purpose that is easy to be fixedly arranged on insulating base frame.

The terminal structure of the smart card connector that the utility model provides, its beneficial effect is:

At first, the external connection terminals of the first terminal group and second terminal group concentrates on the same side, makes terminal group can be fixedly arranged on insulating base frame easily, and then reaches and be easy to connect aerial lug or adapter; Secondly, blocking contacted terminal group with spirit only needs one group of die apparatus with the detecting terminal group, can reduce like this and make the required mould of terminal group, and then realize reducing cost, assembling facility.

The defective that the utility model is primarily aimed at that existing commonly used connector is difficult to because of the two-way separation of external connection terminals causes externally to connect and material cost height, assembling are difficult for is improved, and has realized the summary of outside connection and the reduction of cost.
