Description

Technical Field

[0001] This utility model belongs to the field of communication module technology, specifically relating to an improved waterproof communication module. Background Technology

[0002] Currently, most communication modules use a sealing potting method between the connector and the housing. Because the connector and housing are sealed with potting compound, disassembly and repair are difficult. Furthermore, this method requires first potting and securing the connector and housing before installing the circuit board for soldering, making automated SMT production impossible and increasing labor costs. In traditional processes, after the connector and housing are assembled and potted together, the circuit board lacks connector plugs, requiring the creation of a dedicated connection testing fixture. After soldering the connectors to the circuit board and housing, if rework is needed, multiple connectors on the housing must be removed from the circuit board simultaneously, making the process irreversible. Moreover, this method results in a long adhesive curing period, increasing production costs. Therefore, developing an improved waterproof communication module that overcomes these shortcomings is crucial. Utility Model Content
