Description

Sim card connector terminal clamping device

Affiliated technical field

The utility model relates to a kind of sim card connector terminal clamping device, refers in particular to a kind of terminal clamping device that can reach ultrathin sim card connector.

Background technology

Along with science and technology progress with rapid changepl. never-ending changes and improvements, improving constantly of daily life level, thereby make people be: compact to the requirement of various electronic equipments, promote that further each electronic equipment develops towards compact direction, small product size requires more little that youngest also can require more and more littler for its employed part, the mobile phone that often uses in the daily life wherein, the structure of the sim card connector that it uses above are will cube more and more littler.Used on the market sim card connector generally all is made up of insulating body and terminal at present, therefore structure is the finished product that is assembled by the back processing procedure, because of the moulding of considering insulating body reaches in order to guarantee a series of factors such as interfering edge between terminal and the insulating body, it is thick that the volume of insulating body and thickness all can design relatively, thereby make the integral thickness of finished product thicker.Save shared space for the thickness that reduces insulating body, the someone adopts the mode of Molding (moulding is penetrated in embedding) to produce, but the thickness of this method still remains on about 0.5mm.So generally the sim card connector of being made up of insulating body and terminal can't be accomplished ultra-thin structure, satisfies the design requirement of compact product, so connector construction has further improved necessity.

Summary of the invention

For having overcome deficiency of the prior art, main purpose of the present utility model is to provide a kind of sim card connector terminal clamping device, it is to utilize clamping device that the terminal of desiring to be welded in circuit board is done suitable clamping, when welding, can keep or take down the terminal clamping device and adjust product thickness according to the actual needs.

In order to realize above-mentioned purpose, the utility model can be implemented by following technical scheme: plant sim card connector terminal clamping device, this connector is made up of terminal clamping device and a plurality of terminal.

Above-mentioned terminal clamping device is that an insulating material is made, this terminal clamping device is provided with a substrate, the substrate middle part is provided with a plurality of dead slots, this dead slot is used for the elastic arm and the contact site of ccontaining terminal, the two ends of base lower surface respectively are provided with a holding section, and the holding section is provided with plurality of bump, each side are provided with a protuberance at projection away from an end of substrate, form a holding tank between the two adjacent like this projections, this holding tank is used to hold the fixed part of firm terminal.

Above-mentioned terminal comprises elastic arm, contact site, fixed part and weld part.The fixed part both sides respectively are provided with a groove, when terminal group is loaded in the terminal clamping device, this moment, groove was arranged in the holding tank, the groove two side is against the front-back of projection, protuberance card on the projection is established the upper side of terminal fixed part, terminal is stable in the terminal clamping device, thereby the elastic arm and the contact site of terminal is placed in the dead slot of terminal clamping device.

Before assembling, terminal is to be joined together to form terminal group with terminal material belt, terminal group being assembled in the terminal clamping device so that reach simple and rapid assembling, removes terminal material belt then.Because the structure of terminal fixed part and the physical dimension of the holding tank on the terminal clamping device are all very little, thereby make assembly and disassembly between terminal and the terminal clamping device all than being easier to, and dismounting terminal clamping device can not damage terminal yet after this sim card connector is welded on circuit board, whether the client can keep the terminal clamping device according to the thickness specification of product like this, thereby makes product at thickness certain elastic space be arranged.

Compared to before technology, the utlity model has following advantage: the utility model provides a kind of structure of ultra-thin sim card connector, this connector adopts the terminal clamping device to fix terminal, again terminal is welded on the circuit board, because terminal clamping device and terminal all are easy to assembling and dismounting, thereby be convenient to both can keep the terminal clamping device on the circuit board and also can dismantle the terminal clamping device in that this connector is welded to according to client's demand, reaching has certain elasticity to change the space on product thickness, and the terminal clamping device of this connector is simple in structure, can reach recycling of materials taking down the terminal clamping device, thereby the saving materials and parts reach the purpose that reduced cost.

For the personnel that utility model purpose of the present utility model and architectural feature can further be allowed be familiar with this skill understand, will cooperate appended graphicly, with a specific embodiment the utility model is further detailed.
