Description

An ultra-low profile memory socket designed with spring-loaded terminals

technical field

The utility model relates to the technical field of ultra-low height memory sockets, in particular to an ultra-low height memory socket designed with spring-type terminals.

Background technique

In the prior art, the memory socket is a connector for connecting memory sticks and circuit boards. In order to adapt to different terminal server spaces, memory sockets are divided into standard type and ultra-low height type. The height of the ultra-low height type is higher than that of the standard type. The height is 1.3mm smaller. As for the metal terminals used in the ultra-low height memory socket, due to the reduced height, the force arm of the terminal becomes shorter, and the positive force of the terminal with a short force arm will increase, the insertion force of the memory module will also increase, and the reliability will decrease. As we all know, when inserting a memory module, a large insertion force will cause many problems, such as the memory is not inserted smoothly, and the user experience is poor; too much force when inserting is easy to damage the memory module, such as the terminal is easy to cross, Even the plastic body is cracked. Therefore it is necessary to improve it.

Utility model content

Aiming at the deficiencies of the existing technology, the purpose of this utility model is to provide an ultra-low height memory socket designed with spring-type terminals. Without affecting the height of the product, the insertion force of the product can be reduced and the product can be improved by improving the terminal design. The purpose of product reliability.

In order to achieve the above object, the technical solution adopted by the utility model is.

An ultra-low-height memory socket designed with spring-type terminals, including an ultra-low-height memory socket main body, the main body of the memory socket is provided with a slot, terminals are installed on both sides of the slot, and welding feet are provided on the lower part of the terminal. The upper part of the terminal is provided with an electrical contact part, and the middle part of the terminal is provided with at least one elastic bending part.

In a further technical solution, along the thickness direction of the main body of the memory socket, the lower end of the middle part of the terminal is bent outward and staggered by a set distance, and then extends upward to form an elastic part, and the upper end of the elastic part extends into the slot , the elastic portion is provided with at least one elastic bending portion.

In a further technical solution, along the thickness direction of the main body of the memory socket, the elastic bending portion protrudes toward the inner direction or toward the outer direction.

In a further technical solution, the middle part of the terminal is provided with 1 to 3 elastic bending parts.

After adopting the above structure, the utility model has the advantages compared with the prior art: the utility model adds a bending feature in the middle of the terminal, the terminal design is similar to a spring shape, and the increased elastic bending part indirectly increases the terminal's flexibility. The length of the moment arm reduces the positive force of the terminal and reduces the insertion force of the memory module.

In addition, the terminal of the present invention can make the stress distribution more uniform and reasonable, and reduce the risk of stress concentration.

Detailed ways

The following descriptions are only preferred embodiments of the present utility model, and do not therefore limit the protection scope of the present utility model.

Embodiment, see shown in Fig. 1 to Fig. 2, a kind of design has the memory socket of ultra-low height of spring type terminal, comprise the memory socket main body 1 of ultra-low height, memory socket main body 1 is provided with slot 2, slot 2 Terminals 3 are installed on both sides of the terminal 3, the lower part of the terminal 3 is provided with a welding foot 5, the upper part of the terminal 3 is provided with an electrical contact part, the middle part of the terminal 3 is provided with at least one elastic bending part 4, and the middle part of the terminal 3 is provided with at least one bend.

Along the thickness direction of the main body 1 of the memory socket, the lower end of the middle part of the terminal 3 is bent outward and staggered by a set distance, and then extends upward to form an elastic part. The upper end of the elastic part extends into the slot 2, and the elastic part At least one elastic bending part 4 is provided.

In a preferred embodiment, the middle part of the terminal 3 may be provided with 1 to 3 elastic bending parts 4 . Along the thickness direction of the memory socket main body 1 , the elastic bending portion 4 protrudes toward the inner direction or toward the outer direction.

The utility model adds a bending feature to the middle part of the terminal 3. The design of the terminal 3 is similar to a spring shape. The added elastic bending part 4 indirectly increases the length of the force arm of the terminal 3, thereby reducing the positive force of the terminal 3. In addition, the terminal 3 can make the stress distribution more uniform and reasonable, reducing the risk of stress concentration.

The utility model designs the terminal 3 as a spring-type terminal 3 by increasing the number of elastic bending parts 4 of the terminal 3 to increase the length of the force arm of the terminal 3. According to the positive force formula, the longer the force arm, the smaller the positive force , The insertion force of the memory stick is also reduced, and the smaller insertion force will make the product application more comfortable and the product performance more reliable.

The above content is only a preferred embodiment of the present utility model. For those of ordinary skill in the art, according to the idea of the present utility model, there will be changes in the specific implementation and scope of application. The content of this specification should not be understood as Limitations on the Invention.
