Description

Electrical connector

The present invention relates to an electrical connector, and more particularly to an electrical connector that can mount an electronic card and has an improved latching mechanism.

At present, an electrical connector is generally used in the industry to connect a memory electronic card to a computer motherboard. The insulative housing of the electrical connector is provided with a slot for receiving a memory electronic card, and the two ends of the insulating body are provided with a rotatable ejection device. To facilitate the withdrawal of the memory electronic card. Usually, several such connectors are arranged side by side in a high density on the motherboard to facilitate system function expansion. However, with the development of computer miniaturization, more electronic components are installed on the motherboard, and the two ejector devices of the electrical connector occupy a large space when used, and the manufacturer has designed to use only one ejector device. Electrical connector.

The prior art relating to the present invention is described in U.S. Patent No. 5,660,552, issued Aug. 26, 1997, which discloses a socket connector for mounting a memory electronic card, the socket connection The device comprises an insulating body provided with a longitudinal slot, an ejector device disposed at one end of the insulating body, and a resilient arm disposed at the other end of the insulating body. The elastic arm is integrally formed by the insulating body and is located in the extending direction of the slot, and the upper end of the elastic arm is provided with a protrusion. When the memory electronic card is loaded into the slot, the longitudinal end of the memory electronic card abuts against the protrusion to elastically deform the elastic arm, and protrudes from the elastic arm when the memory electronic card moves to the slot position in the depth direction of the slot. The elastic force is inserted into the opening of one end of the memory electronic card. Due to the elastic arm system The edge body is integrally formed, and the elastic arm is weak and thus easily damaged.

Another conventional technique related to the present invention is disclosed in Chinese Patent No. 201142447, issued Oct. 29, 2008, which discloses another electrical connector for mounting a memory electronic card. The connector includes: an insulative housing having a socket for inserting a memory electronic card in a longitudinal direction, a receiving slot on each side of the slot; a plurality of conductive terminals received in the receiving slot; and an ejection device a fastening portion that is pivotally connected to one end of the insulative housing and has an opening; and an elastic body disposed at the other end of the insulative housing, the main body portion is provided with a fixing portion, and the inner side is provided with a fixing portion A retaining portion is provided that can be snapped to the other opening, and the elastic body can be longitudinally deformed along the insulating body. When the memory electronic card is loaded into the slot, one side of the memory electronic card abuts against the elastic body and elastically deforms, and the initial loading position of the memory electronic card and the final mounting position are displaced in the longitudinal direction. During the insertion process, the elastic body applies a longitudinal pressure to the memory electronic card, and the electronic card moves to the final installation position under the action of the user's insertion force and the elastic force of the elastic body. Since the elastic body applies a longitudinal pressure to the electronic card during insertion of the memory electronic card into the electrical connector, the pressure causes the friction between the memory electronic card and the insulating body and the conductive terminal to increase in the longitudinal direction.

Therefore, it is necessary to design an electrical connector that overcomes the above-mentioned deficiencies of the prior art.

The technical problem to be solved by the present invention is to provide an electrical connector which is structurally reliable, easy to use, and has less friction with an electronic card.

In order to solve the above technical problem, the present invention adopts the following technical solution: an electrical connector for inserting a longitudinally elongated electronic card, the electronic card having at least one opening at each end thereof, the electrical connector comprising: An insulating body, which is a longitudinal insulator, The insulative housing includes a longitudinally-shaped slot disposed along a longitudinal direction thereof; an ejecting mechanism includes an ejecting device rotatably fixed to the first end of the insulative housing, the ejecting device including a snap-fastenable opening to one end of the electronic card a latching mechanism is disposed at a second end of the insulative housing, the latching mechanism includes a slot provided at the second end of the insulative housing and a metal elastic body received in the slot, the slot extending to the opening a slot, the metal elastic body includes a pair of elastic portions disposed on two sides of the slot, and a pair of latching portions extending from the elastic portion into the slot, the pair of latching portions for latching the other end of the electronic card An opening, and the pair of hook portions are movable along the insulating body transversely to the slot and the slot.

Compared with the prior art, the electrical connector snap mechanism of the present invention adopts a metal elastic body, which has high strength and is structurally reliable. The metal elastic body is located in the slot of the slot and can be moved to the slot in the lateral direction of the insulative housing when the electronic card is inserted. The metal elastic body does not exert longitudinal pressure on the electronic card, thereby reducing the insertion of the electronic card. Friction with the insulating body and the conductive terminals.
