Card connector

The present invention relates to a connector, and more particularly to a card connector for housing an electronic card.

According to the development of society and the advancement of science and technology, electronic products are gradually developing towards light and thin, so that people can carry them with them. In order to meet the development needs of electronic products, electronic components used in electronic products, such as card connectors, are also moving toward thinner and lighter. A conventional card connector for accommodating an electronic card includes an insulative housing, a plurality of terminals disposed on the insulative housing, and a shielding housing covering the insulative housing. A plug-in space is formed between the shielding shell and the insulative housing for receiving the electronic card. Each of the terminals has a fixing portion, a contact portion connected to one end of the fixing portion, and a welding portion connected to the other end of the fixing portion. The fixing portion is fixed in the insulating body, the contact portion extends into the insertion space, and the soldering portion protrudes outside the insulating body. The soldering portion of the card connector is soldered to a circuit board by Surface Mount Technology (SMT).

However, when a conventional card connector is soldered to a circuit board by SMT technology, since the temperature is high and the thickness of the insulating body is thin, the insulating body is liable to be deformed and recessed, thereby affecting the conventional card connection. The function of the device.

The purpose of this creation is to overcome the deficiencies in the prior art described above and to provide a card connector that ensures functionality.

The present invention provides a card connector comprising an insulative housing, a plurality of terminals, at least one reinforcing member, an upper housing and a lower housing. The insulating body has a bottom wall, and the bottom wall defines at least one matching groove. The terminal is integrally formed on the insulative body. The reinforcing member is integrally formed on the bottom wall of the insulative housing, and has a main body portion and a mating portion connected to the main body portion. The main body portion is integrally formed in the bottom wall, and the fitting portion is exposed in the fitting groove. The upper casing covers an upper portion of the insulative housing, and a socket space is formed between the upper casing and the insulative housing. The lower casing is fixed to the bottom of the insulating body and has a bottom plate, and the bottom plate is punched with at least one stop groove. The rear groove wall of the stop groove extends out of a stop portion, and the stop portion extends into the engagement groove and is hooked to the bottom of the fitting portion.

In summary, the creative card connector is hooked to the bottom of the mating portion of the reinforcing member by the stop portion of the lower casing, and is soldered to a circuit board by the surface mount technology. The stop portion provides an upward supporting force on the bottom of the mating portion to support the bottom of the mating portion, and the bottom wall of the insulating body maintains the original shape under the action of the reinforcing member and the stop portion, thereby ensuring the function of the card connector. .
