Sealing wax is a wax material of a seal which, after melting, hardens quickly (to paper, parchment, ribbons and wire, and other material) forming a bond that is difficult to separate without noticeable tampering. Wax is used to verify something such as a document is unopened, to verify the sender's identity, for example with a signet ring, and as decoration. Sealing wax can be used to take impressions of other seals. Wax was used to seal letters close and later, from about the 16th century, envelopes. Before sealing wax, the Romans used bitumen for this purpose.

The invention is applicable to the technical field of earphone connectors and discloses an earphone connector and a manufacturing method thereof, a mobile terminal having the earphone connector. The earphone connector includes an earphone holder main body has one end provided with a jack for insertion of an earphone plug, a sealing wax piece which is embedded in the jack, a terminal assembly which is inserted to the earphone holder main body, a rear cover assembly which covers the two sides of the earphone holder main body, and a sealing assembly which is filled between the rear cover assembly and the earphone holder main body. According to the invention, the sealing wax piece characterized by high-temperature resistance and insusceptibility to shrinkage or deformation is installed to the jack of the earphone holder main body, and a product can be directly subject to an IR furnace and welded to a PCB, such that the earphone connector addresses the problem of manual welding of conventional water-proof earphone holders, increases the efficiency of welding PCBs, lowers manufacturing cost of products, and meets requirements for water resistance in a manner that even if the earphone connector is in water under a certain pressure, water does not easily get into the mobile terminal via through the earphone holder.
