## Title
Micro combined connector structure

## Abstract

The present invention provides an improved micro combined connector structure, wherein a connector is structured to include a base, a cover, a movable cover and an earth strip. The base is provided with first and second containing recesses disposed therein, wherein the first containing recess enables electrical connecting to a SIM (Subscriber Identity Module) card, and the second containing recess enables electrical connecting to a memory card. A movable cover is fittingly disposed corresponding to position of the second containing recess of the base, and a protruding piece is located on the movable cover corresponding to the earth strip located on a side of the base. Closing of the movable cover enables the protruding piece and the earth strip to make contact and produce an electrical conduction, thereby enabling the movable cover to form an earthing state to achieve the objective of preventing interference and reducing noise.

## Background
BACKGROUND OF THE INVENTION
(a) Field of the Invention
The present invention relates to an improved micro combined connector structure, and more particularly to a connector enabling a SIM (Subscriber Identify Module) card and a memory card to be inserted therein.
(b) Description of the Prior Art
A connector of prior art has a structure enabling a memory card to be directly disposed on terminals of a containing recess, whereupon an upper cover press fits and thereby fixedly clasps the memory card. However, the direct press fitting method of the upper cover easily results in the upper cover opening due to inadvertent knocking when in use, thereby resulting in the inability to effect normal electrical connection between the memory card and the terminals, or results in the memory card coming loose leading to loss thereof.
Furthermore, a connector of prior art that has not been provided with earthing means, and thus easily results in noise interference occurring when in use, which further causes the connector to produce problems of wrong access to the memory card.
Hence, the inventor of the present invention proposes to resolve and surmount existent technical difficulties to eliminate the aforementioned shortcomings of prior art.
SUMMARY OF THE INVENTION
The art of the present invention provides an improved micro combined connector structure, and more particularly provides a connector enabling a SIM (Subscriber Identify Module) card and a memory card to be inserted therein, moreover, the connector is disposed with an earth strip that enables achieving the objective of preventing interference and reduce noise.
To enable a further understanding of said objectives and the technological methods of the invention herein, brief description of the drawings is provided below followed by detailed description of the preferred embodiments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Referring to FIG. 1 and FIG. 2, which show an improved micro combined connector structure of the present invention provides, wherein a connector A is structured to primarily comprise a base B, a cover piece C, a movable cover D and an earth strip E. A first containing recess B1 and a second containing recess B2 are defined in the base B, and a plurality of terminals B3 are respectively configured within the first containing recess B1 and the second containing recess B2. A plurality of protuberances B4 and bilateral oblique portions B5 are located on the first containing recess B1, and bilateral protruding shafts B6 and a protruding rail B7 are located on the second containing recess B2. Accordingly, the cover piece C is disposed on the first containing recess B1, and a plurality of through holes C1 defined in the cover piece C respectively join with the corresponding protuberances B4 of the first containing recess B1. Furthermore, the movable cover D is fittingly disposed on the second containing recess B2, and bilateral arc holes D1 defined in the movable cover D are used to respectively join with the corresponding protruding shafts B6 of the second containing recess B2.
A protruding piece D2, a fastening member D3 and a plurality of clasp fastening members D4 are located on the movable cover D. The earth strip E is fittingly disposed on a side of the second containing recess B2 corresponding to position of the protruding piece D2 of the movable cover D.
When the movable cover D is closed, contact between the protruding piece D2 and the earth strip E effects an electrical connection, thereby enabling the movable cover D to assume an earthing state, thus achieving the objective of preventing interference and reducing noise.
Referring to FIG. 3, FIG. 4 and FIG. 5, which show an embodiment of the improved micro combined connector structure of the present invention, wherein a memory card F is disposed within the movable cover D, thereby enabling the memory card F to be contained between the plurality of clasp fastening members D4, whereupon the movable cover D is downwardly pressed causing the memory card F to abut against the plurality of terminals B3 within the second containing recess B2. The movable cover D is then pushed in a direction to cause the fastening member D3 of the movable cover D to slide clasp onto the protruding rail B7 of the base B, thereby effectively preventing the movable cover D from easily opening because of knocking to achieve the objective of forming a tight join.
When the movable cover D is pressed downward, the protruding piece D2 and the earth strip E make contact and produce an electrical conduction, thereby enabling the movable cover D to form an earthing state, and effectively achieving the objective of preventing interference and reducing noise.
Referring to FIG. 6, FIG. 7 and FIG. 8, wherein a SIM (Subscriber Identity Module) card G is inserted within the first containing recess B1 of the connector A, thereby enabling the SIM card G to form an electrical connection with the plurality of terminals B3 within the first containing recess B1, and facilitating implementation of data transmission and access using the connector A.
When extracting the SIM card G, an end of the SIM card G need only be pressed downward towards the oblique portions B5 of the first containing recess B1, thereby causing another end of the SIM card G to rise upward, whereupon the raised end is pushed to enable unimpeded extraction of the SIM card G.
The memory card F (see FIG. 3) can be a MMC (Multi Media Card), a Flash Card or related micro storage card.
In order to better explicitly disclose advancement and practicability of the present invention, a comparison with prior art is described hereinafter:
Shortcomings of Prior Art
1. Easily results in an upper cover opening due to inadvertent knocking when in use, thereby resulting in the inability to effect normal electrical connection between the memory card and terminals, or results in the memory card coming loose leading to loss thereof.
