Title: Memory card connector

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a connector, more particularly to a memory card connector that can be used to fasten a memory card therein. 
     2. Description of Related Art 
     A memory card connector is widely used in a computer motherboard so a memory module is able to be installed therein, thus a central process unit (CPU) can access the memory module through the memory card connector. The memory card connector is such as an EDO DRAM, SDRAM, DDR DRAM and the latest DDRII RAM. 
     The stability of the computer mainframe relies on whether the memory module can be firmly fastened on the memory card connector. When the memory module is not able to be firmly fastened on the memory card connector, an error may occur when the computer mainframe is accessing data and a computer crash down is therefore caused. 
     To overcome the disadvantages mentioned above, a novel memory card connector is provided by the present invention to improve such shortages. 
     SUMMARY OF THE INVENTION 
     One object of the present invention is to provide a memory card connector, which can be used to firmly fasten a memory module within the memory card connector. 
     Another object of the present invention is to provide a memory card connector, of which structure is simple and production cost is lower. 
     For achieving the objects mentioned above, a memory card connector is provided by the present invention, comprises an insulation main body on which an insertion slot and a plurality of terminal slots are installed, and two ends thereof are respectively provided with a tower having a guiding slot, a positioning concave slot and a limiting block, wherein the insertion slot and the guiding slot are served to be inserted with a memory card; a plurality of terminals respectively received in the plural terminal slots; and two lugs, each of the lugs has a pin shaft and a limiting part, the pin shaft is disposed in the positioning concave slot, the lug is limited in the limiting block when the lug is pivotally moved through the pin shaft so as to respectively buckle on the tower.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring from  FIG. 1  to  FIG. 4 , wherein  FIG. 1  is a schematic, exploded view of the memory card connector of one preferred embodiment of the present invention;  FIG. 2  is a schematic, partially-enlarged cross sectional view of the tower of one preferred embodiment of the present invention;  FIG. 3  is a schematic view of the lug of one preferred embodiment of the present invention;  FIG. 4  is a schematic view illustrating the assembly of the lug and the memory card connector of one preferred embodiment of the present invention. 
     As shown in figures, the memory card connector  1  provided by the present invention, which can be served to connect a memory module  2 , comprises an insulation main body  10 , a plurality of terminals  20 , and two lugs  30 . 
     The insulation main body  10  is made of an insulation member, e.g. but not limited to, plastic, an insertion slot  11  and a plurality of terminal slots  12  are installed thereon and two ends thereof are respectively installed with a tower  13 , the tower  13  has a guiding slot  131 , a positioning concave slot  132  and a limiting block  133 . The insertion slot  11  and the guiding slot  131  are served to be inserted with the memory module  2 ; the positioning concave slot  132  and the limiting block  133  are cooperated with the lugs  30 . 
     The plural terminals  20  are respectively received in the plural terminal slots  12  so as to form an electrical connection, the terminals  20  are conventional terminals therefore would not be further illustrated. 
     As shown in  FIG. 3 , each of the two lugs  30  has a pin shaft  31  and a limiting part  32 , wherein the pin shaft  31  is disposed in the positioning concave slot  132 ; the limiting part  32 , e.g. but not limited to, protrudes from the bottom of the lug  30 . The lug  30  is limited in the limiting block  133  through the limiting part  32  when the lug  30  is pivotally moved through the pin shaft  31 , so the two lugs  30  are respectively buckled on the corresponding tower  13 . Furthermore, the top end of the lug  30  is installed with at least one step-like transversal strip  33  to increase friction, so the tower  13  is easier to be pulled by a user. 
     The pin shaft  31  is disposed on top of the limiting part  32  and is in a round column shape, and protrudes from two ends of the lug  30 , the pin shaft  31  is able to be received in the positioning concave slot  132  for operating a pivotal motion. 
     Two lateral ends of the lug  30  are further installed with a buckling block  34 . The buckling block  34  is disposed at the same side where the limiting part  32  is installed and is disposed on top of the pin shaft  31 , and protrudes from the two ends of the lug  30  so as to buckle on the tower  13 . Two ends of the buckling block  34  respectively have a reversed angle part (not shown) and the two reversed angle parts have different angles. 
     As shown in  FIG. 4 , in assembly, the pin shaft  31  is received in the positioning concave slot  132  so as to achieve the assembly. When the lug  30  is outwardly and pivotally moved, the limiting part  32  thereof is disposed against and positioned in the limiting block  133 ; when the lug  30  is inwardly and pivotally moved, the limiting part  32  thereof is released from the limiting block  133  and is disposed against and positioned on one end of the tower  13 , then is buckled on the tower  13  through the buckling block  34 , so the memory module  2  is fastened therein. 
     As mentioned above, with the memory card connector provided by the present invention, the memory module can be firmly fastened in the memory card connector, and the structure of the memory card connector is simple and product cost thereof is lower. 
     It is to be understood, however, that even though numerous characteristics and advantages of the present embodiments have been set forth in the foregoing description, together with details of the structures and functions of the embodiments, the disclosure is illustrative 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.
