Description

Electronic card connector

The present invention relates to an electronic card connector, and more particularly to an electronic card connector having a terminal protection structure.

With the development of communication and digital electronic technology, there are more and more requirements for the functions of related devices, the capacity of required storage materials, and the miniaturization of electronic components. Especially in the miniaturization of electronic components, how to ensure the stability of electronic components And to improve product production yield is particularly important.

A common electronic card connector, such as an Express card connector, has a fixed structure for connecting the conductive terminals to the printed circuit board, but the fixed structure only provides a series of blocking blocks between the conductive terminals, only for the conductive terminals. Partial isolation is made in the lateral direction of each other, which does not limit the conductive terminals in multiple orientations. Therefore, in the process of mounting and mounting the electronic card connector to the printed circuit board, since the terminals are relatively small and closely arranged, the connection end of the conductive terminal is easily deformed or misaligned when pressed by an external force. Affects the connection accuracy of the printed circuit board, that is, the conductive terminal connection end cannot be accurately docked with the corresponding solder joint on the printed circuit board. In addition, this will make the product scrapped, increase the production cost, and does not meet the development trend of cost saving, stable and reliable electrical connectors.

In order to avoid the above problems, the present invention proposes a new type of electronic card connector to make up for its deficiencies.

It is an object of the present invention to provide an electronic card connector having a terminal soldering end holding structure.

To achieve the above objective, the present invention provides an electronic card connector including an insulative housing, a shielding housing, a card ejecting mechanism, and a plurality of conductive terminals. The front end surface of the insulative housing is provided with a plurality of fixing arms, and the shielding housing is covered on the insulative housing. And forming a receiving space for accommodating the electronic card, the front end surface of the insulating body is provided with a plurality of fixing arms, and the conductive terminal is received in the insulating body, and comprises a clamping portion, a fixing portion bent downward from the clamping portion, and a fixing portion at the fixing portion a soldering portion formed at the end, wherein a width of the conductive terminal holding portion and the fixing portion is greater than a contact portion and a solder portion.

Compared with the prior art, the electronic card connector of the present invention has the following effects: the fixing portion provided by the conductive terminal is fixed in the fixing groove between the fixed arms of the insulating body, and the conductive terminal is protected from being deformed by external force and deformed. At the same time, improve the requirements of coplanarity, improve product yield and good welding results.

The electronic card connector 100 of the present invention includes an insulative housing 30, a conductive terminal 40 received in the insulative housing 30, a shielding housing 10, and a card ejecting mechanism 20 mounted on the side of the shielding housing 10. The insulative housing 30 is received and mounted on the lower portion of the front end of the shielding case 10, thereby forming a receiving space (not labeled) for accommodating the electronic card surrounded by the insulative housing 30 and the shielding housing 10. The card ejecting mechanism 20 is mounted. On the side of the shielding case 10, the function of inserting and withdrawing the electronic card is completed.

Referring to the second to fourth embodiments, the insulative housing 30 includes a base portion 31, a guiding arm 33 extending from the opposite ends of the base portion 31 in the direction of pulling out the electronic card, and extending from the central portion of the base portion 31 toward the electronic card. Located on two guiding arms A tongue 34 is formed between the 33, and a plurality of terminal receiving grooves (not shown) are formed in the front portion of the tongue portion 34. A plurality of terminal fixing arms 32 are protruded from the front end surface of the insulating body 30, and the bottom of the fixing arm 32 extends to both sides. The holding portion 321 is formed, and a terminal fixing groove 322 that communicates with the terminal receiving groove is formed between the two holding portions 321 .

The conductive terminal 40 includes a contact portion 41, a clamping portion 42, a soldering portion 44, and a fixing portion 43 of the connecting portion 44 and the clamping portion 42 which are bent and extended from the clamping portion 42 and thereby form a bend Part 45. The contact portion 41 and the clamping portion 42 are received in the insulative housing 30 through the terminal receiving groove of the tongue portion 34. The contact portion 41 is exposed at the end of the tongue portion 34 to be electrically contacted with an electronic card (not shown). The holding portion 42 is received and fixed in the terminal receiving groove, and the clamping portion 42 has a width larger than the contact portion 41. A pair of card slots (not labeled) are symmetrically disposed in the middle portion of the clamping portion 42 for corresponding to the terminal receiving groove. The holding member (not shown) is held. The fixing portion 43 is formed by being bent downward from the nip portion 42 and has a width corresponding to the width of the nip portion 42 and larger than the width of the welded portion 44, whereby the stepped abutting portion 431 is formed at the joint with the welded portion 44. The fixing portion 43 and the fixing groove 322 between the two fixing arms 32 have substantially the same width. When the conductive terminal 40 is received in the insulative housing 30, the fixing portion 43 of the conductive terminal 40 is received in the fixing groove 322 between the two fixing arms 32, and the abutting portion 431 of the fixing portion 43 abuts against the clamping of the fixing arm 32. The fixing portion 32 of the two sides defines the left and right positions of the conductive terminal 40. The abutting portion 431 abuts the holding portion 321 to define the upper and lower positions of the conductive terminal 40. Thus, the terminal fixing groove 322 fixes the fixing portion of the conductive terminal 40. 43 multi-directional covering, avoiding interference of external objects on the conductive terminals 40, thereby protecting the conductive terminals 40 from deformation and damage due to external forces, thereby improving product yield.

Compared with the prior art electronic card connector, the electronic card connector 100 of the present invention is covered in the fixing groove 322 between the fixing arms 32 of the insulative housing 30 by the fixing portion 43 of the conductive terminal 40, thereby protecting the conductive terminal 40 at During the production process, it will not be deformed and dislocated due to external force, and at the same time, the requirement of coplanarity is improved, and further, a good welding effect is provided to ensure the stability of the connection with the printed circuit board. Of course, the fixing portion 43 may also be composed of a plurality of portions having different widths.

In summary, the present invention complies with the requirements of the invention patent and submits a patent application according to law.
