The present invention relates to a card edge connector, especially to a latching structure of the card edge connector.
U.S. Pat. No. 9,385,452 discloses a card edge connector. The card edge connector includes an insulative housing, a plurality of terminals retained in the housing, and an ejector. The ejector includes a base portion and a pair of wing portions extending upwardly from both sides of the base portion. The card edge connectors are usually arranged side by side to save space, making it difficult to unlock with the finger by pressing the wing portion. In this case, an external tool such as a screwdriver, a ball-point pen, etc. is generally used to press against the upper surface of the wing portion to unlock, resulting in the upper surface or even the structure of the wing portion being damaged.
Therefore, it is desired to provide a new card edge connector.
To achieve the above desire, a card edge connector includes an insulative housing, a plurality of terminals retained in the housing, and a latching structure. The housing defines a card receiving slot. The latching structure includes a locking portion and an operating portion. The operating portion defines an operating surface. The operating portion is made of insulative material, and a metal plate is attached upon the operation surface or embedded within the operation portion for resisting an external tool imposed thereon so as to prevent damage of the operation portion either on superficially or structurally.

The locking portion 31 includes two vertical walls 311 and two latch arms 312 under the vertical walls 311. A card receiving groove/slot 313 is defined between the two vertical walls 311. Each of the latching arms 312 is used to lock to the housing 1, with a locking block 314 protruding inwardly at a free end thereof. a shaft portion 331 protrudes outwardly from each of opposite sides of the mounting portion 33 and is assembled in the housing, so that the locking portion 31 is pivotally fixed to the housing 1. The thickness of the mounting portion 33 in a vertical direction gradually decreases in the elongated direction away from the card slot 11 as best shown in

Understandably, in both two embodiments the metal plate is associated with the operation portion by either an insert-molding way or an assembling way, and is upwardly exposed to an exterior for confrontation with the external tool externally. Alternately, the metal plate may be unexposed upwardly to the exterior but hidden within the operation portion for structure enhancement internally. Disregarding whether the metal plate is exposed externally or hidden internally, the operation portion is reinforced structurally with less risks of breakage.
It is to be understood, however, that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrated only, and changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed.
