Conductive terminal of breaking-PIN prevention and card connector

Abstract

The invention discloses a conductive terminal of breaking-PIN prevention and a card connector. The conductive terminal comprises a sheet material body and a terminal body. The terminal body comprises a connection sheet, a main body sheet, a contact terminal and a pair of breaking prevention terminals. By using the breaking prevention terminals, a breaking PIN problem of the contact terminal during a card plugging and unplugging process can be effectively prevented. Simultaneously, a tail end of a second contact arm of the contact terminal is accommodated in a groove of the main body sheet in an inclination mode so that a SIM card can be guaranteed to be smoothly inserted into a card accommodation chamber and the breaking PIN problem of the contact terminal can be prevented. Bending portions of the contact terminal and the breaking prevention terminals are designed to be in an arc shape so that the conductive terminal can be effectively prevented from scratching the inserted SIM card. Through using the card connector of the conductive terminal, an ultrathin design can be realized. During the card plugging and unplugging process, the card body is not damaged and the contact terminal can be effectively protected. A condition that the contact terminal is deformed so that a breaking PIN phenomenon is generated during the card plugging and unplugging process or a state of a empty card frame is prevented.

Description

Technical field [0001] The invention relates to a conductive terminal and a card connector, in particular to a PIN-proof conductive terminal and a card connector, and belongs to the technical field of electrical connection elements. Background technique [0002] As the size of electronic products such as mobile phones develops towards ultra-thinness, it is bound to require that the internal components such as card connectors become thinner and lighter. As an essential part of a mobile phone, a card connector generally includes a plastic body, a plurality of conductive terminals embedded in the plastic body, and a metal shell covered on the plastic body. The conductive terminal has a convex contact portion, and The inserted SIM card contacts to realize electrical connection. [0003] As mentioned above, the card connector must be thinner and thinner, that is, the total height is reduced, which leads to a large space restriction on the structural design of the conductive terminal.

Problems solved by technology

[0003] As mentioned earlier, the card connector must become thinner and thinner, that is, the total height is reduced, which leads to a large space restriction on the structural design of the conductive terminal. When inserting and removing the SIM card in a limited space, it is easy to cause the SIM card Drag the contact part of the conductive terminal until it is warped and deformed (the so-called collapsed PIN phenomenon in the industry), especially when the SIM card to be inserted is a small Micro-SIM card with a card holder or card holder or an empty card frame, it is particularly prone to occur The PIN collapse phenomenon leads to the failure of the function of the card connector, which seriously affects the product quality and market reputation
