DESCRIPTION OF EMBODIMENTS
To make the objectives, technical solutions, and advantages of the present invention more comprehensible, the following further describes the embodiments of the present invention in detail with reference to the accompanying drawings.
Referring to FIG. 2 and FIG. 3, a memory connector is provided, including a base 1, where the base 1 includes a base body 1.1 and connectors 1.2 arranged at two sides of the base body 1.1, a first ejector lever 2 is arranged at one end of the base 1, a second ejector lever 3 is arranged at the other end of the base 1, the first ejector lever 2 includes a first fastener 2.1, the first fastener 2.1 is connected to a first force-applying handle 2.2, a lower part of the first force-applying handle 2.2 is connected to the connector 1.2, the first force-applying handle 2.2 is a planar structure, an inner surface 2.21 of the first force-applying handle and a lateral side of a memory module 4 (as shown in FIG. 4) are arranged face to face, and the inner surface 2.21 of the first force-applying handle is used to apply a pulling force to the outside of the base 1, to cause the first fastener 2.1 to break away from a groove 5 on the memory module 4.
In this embodiment of the present invention, a conventional form of opening a memory connector is changed, so that an operation of opening an ejector lever is implemented by means of a pulling force. After a pulling force is applied from an inner surface 2.21 of a first force-applying handle to the outside of a base 1, a first ejector lever 2 rotates, to cause a first fastener 2.1 to break away from a groove on a memory module 4 to eject the memory module 4. In this way, embodiments of the present invention brings better operation comfort and saves a layout space because the width of an ejector lever structure is decreased.
Referring to FIG. 4, the inner surface 2.21 of the first force-applying handle is a force-applying surface. The force-applying surface is arranged in parallel to the lateral side 4.1 of the memory module 4.
When an area of the force-applying surface of the first force-applying handle needs to be increased, the area of the force-applying surface of the first force-applying handle may be appropriately increased in a direction vertical to an upper surface of the memory module, without the need of increasing a width of the entire memory connector, thereby ensuring a layout space on two sides of the memory connector.
Referring to FIG. 3, a first fastener 2.1 is connected to one end of a top of the first force-applying handle 2.2, and the first fastener 2.1 may also be arranged on the top of the first force-applying handle 2.2, while a bottom of the first force-applying handle 2.2 is fastened on the base 1.
When the first ejector lever 2 needs to be opened, a hand is placed on the upper surface of the memory module 4 (as shown in FIG. 4) and an inner side of the ejector lever to apply a pulling force to the inner surface 2.21 of the first force-applying handle. Only a space needs to be considered for completely opening the first ejector lever 2, and no operation space for the hand needs to be reserved on two sides of the first ejector lever 2.
Referring to FIG. 5, the first fastener 2.1 may also be arranged in the middle of the first force-applying handle 2.2, and the second ejector lever 3 may connect to a second force-applying handle 3.2 by using a second fastener 3.1, and a lower end of the second force-applying handle 3.2 is fastened on a structure of the base 1.
Similarly, when the hand is placed on the inner side of the ejector lever to push the inner surface 2.21 of the first force-applying handle and an inner surface of the second force-applying handle 3.2, to make the first fastener 2.1 and the second fastener 3.1 break away from the groove 5 on the memory module 4, so that the memory module 4 is smoothly plugged or unplugged.
Referring to FIG. 3, for ease of production, the first force-applying handle 2.2 and the first fastener 2.1 is a unibody structure.
Referring to FIG. 2 and FIG. 3, the second ejector lever 3 and the first ejector lever 2 at two ends of the base 1 may use same structure, and the inner surface of the second force-applying handle 3.2 and the inner surface 2.21 of the first force-applying handle are arranged face to face.
Because an ejector lever is opened by using a pulling force and a thumb is placed on the inner side of the ejector lever during the operation to apply the force to a force-applying surface at the inner side of the ejector lever, no operation space needs to be reserved at two sides of the ejector lever, and therefore a greater layout space may be saved. With the structure in embodiments of the present invention, a width of a memory connector is reduced, an operation space required for an existing structure is saved, and side-by-side layout of memory modules can be implemented on a module with a standard 8U (322.25 mm) width. During the layout of the module with the standard 8U width (322.25 mm), a 4.5 mm guide rail space is reserved on each side. When two groups of memory modules are horizontally placed side by side, an operation space of at least 10 mm is reserved between the memory modules. In this case, the remaining size is 303.25 mm, and a maximum width of opening each memory connector cannot exceed 151.6 mm. The foregoing layout can be implemented by using the memory connector provided in the present invention. When an ejector lever is not opened, the total width of the memory connector according to the present invention is 142.6 mm. After the ejector lever is opened, the total width is 156.1 mm.
Referring to FIG. 1 and FIG. 2, the first ejector lever 2 uses the structure provided in embodiments of the present invention, and the second ejector lever 3 may use either the structure provided in embodiments of the present invention or the structure provided in the prior art. The second fastener 3.1 is connected to the second force-applying handle 3.2. The second force-applying handle 3.2 is configured to apply a force to the upper surface, and an anti-skid line is further arranged on the upper surface. During opening of the second ejector lever, the force applies to the upper surface, to cause, through a generated friction force, the second fastener 3.1 to break away from the groove on the memory module, so that the second ejector lever 3 is opened.
The foregoing descriptions are merely exemplary embodiments of the present invention, but are not intended to limit the present invention. Any modifications, equivalent replacements, or improvements made within the idea and principle of the present invention shall fall within the protection scope of the present invention.
