Problems solved by technology

[0003] However, the contact terminals of the connector are usually higher than the contact surface between the electronic card and the connector. When the card is inserted, the electronic card directly enters after touching the terminals of the traditional card connector, which is easy to crush the terminals and deform the terminals, thereby Bad for the life of the electronic card connector

Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with various embodiments shown in the drawings. However, these embodiments do not limit the present invention, and structural or functional changes made by those skilled in the art according to these embodiments are included in the protection scope of the present invention.

[0020] according to Figure 1 to Figure 3 , the present invention provides a card connector 100 , which includes an insulating body 2 and a plurality of terminals 1 fixed on the insulating body 2 . The terminals 1 are fixed on both sides of the insulating body 2 in two rows. Each terminal 1 is provided with a fixing part 11 fixed inside the insulating body 2, elastic arms 12 and welding parts 13 respectively extending from both sides of the fixing part 11. The contact portion 123 where the card contacts, the terminal 1 also has a bending guide 14 that is bent downward from at least one side of the elastic arm 12 to guide the d...

Abstract

The invention provides a card connector which comprises an insulation body and a plurality of terminals fixed to the insulation body. Each terminal is provided with a fixing portion, elastic arms and a welding portion, wherein the fixing portion is fixed into the insulation body, the two side edges of the fixing portion extend to form the elastic arms and the welding portion respectively, and a contact portion used for making contact with a butt-joint electronic card is formed on each elastic arm. Each terminal is further provided with a plurality of bent guiding parts which are bent downwards from at least one side of the elastic arms so as to guide the corresponding butt-joint electronic card. Due to the facts that each terminal is provided with the bent guiding parts bent downwards from the elastic arms, and when the electronic cards are inserted into the terminals, the electronic cards can firstly make contact with the bent guiding parts, the elastic arms are pressed downwards, and the electronic cards can be smoothly inserted into the terminals and make full contact with the contact portions; due to the design of the bent guiding parts, when inserted into the terminals, the electronic cards can be guided, the height of the elastic arms is gradually decreased, and the phenomenon that the terminals collapse due to the fact that the electronic cards abut against the terminals is avoided.

Description

technical field [0001] The invention relates to an electronic card connector, in particular to a card connector which prevents terminals from collapsing when a card is inserted. Background technique [0002] In recent years, electronic card storage media have been widely used in information appliances, personal computers or portable digital products due to their excellent characteristics such as thinness, shortness, high storage capacity, shock resistance, and repeatable memory. When the electronic card is connected to the computer, the connector must be used as the transmission medium to facilitate the reading and storage of the computer host. [0003] However, the contact terminals of the connector are usually higher than the contact surface between the electronic card and the connector. When inserting the card, the electronic card directly enters after touching the terminals of the traditional card connector, which is easy to crush the terminals and deform the terminals, ...
