Description

Technical Field

[0001] The utility model relates to the technology in the field of stamping dies, in particular to a stamping die structure for producing two materials in one die. Background Art

[0002] With the continuous development of society, the demand of human beings for communication is increasing. The network scale and application scope of the Internet are expanding rapidly, and its technical connotation has also broken through the shackles of the traditional Internet. In recent years, the transmission and exchange of information are developing towards optical networks, and optical fiber communication has become the main transmission means of modern information networks. Therefore, the demand for optical modules in the communication industry is also growing rapidly. In order to meet the increasing demand of the system, optical modules are becoming more and more complex and diverse. Among them, SFP optical modules are used more and more maturely by major mainstream equipment manufacturers all over the world under the specification of the SFP MSA protocol. The SFP optical module, that is, a small form-factor pluggable transceiver optical module. The SFP optical module includes a housing, an internal circuit board, a laser and other electronic components, and the SFP optical module is connected to the circuit board of the device through a cage.

[0003] At present, the housing of the SFP optical module is usually composed of parts of different sizes (such as an upper shell, a tail spring piece, a lower shell, a middle spacer, a middle spacer spring piece and an EMI spring piece, etc.). These parts are usually formed by stamping metal sheet through stamping dies. However, in the prior art, these parts of different sizes are respectively formed by different stamping dies, resulting in a lot of useless waste materials being cut out from large parts. For example, when the upper shell is formed by stamping, a window needs to be opened, and a large piece of useless waste material will be cut out at the window opening position, resulting in waste of materials. Moreover, one set of stamping dies is used for each part, which greatly increases the equipment cost and is not conducive to improving the market competitiveness of products. Therefore, it is necessary to study a solution to solve the above problems. Summary of the Utility Model
