Problems solved by technology

[0009] However, manufacturing variations cannot be ignored during mass production, and a slight height difference occurs at the boundary between the divided casings 120, 130 and the junction cover 140.
Therefore, even if it is attempted to join the annular member 150 to the split case 120 and the split case 130 by laser welding, there is a problem that the joint cannot be reliably joined due to the difference in height.

Abstract

Provided is a waterproof connector which realizes miniaturization and reliable connection. The waterproof connector (1) comprises a lower shell (11), an upper shell (12), a cover (20) and terminal parts (13), the lower shell is formed by light-absorption materials, the upper shell is formed by transmittance materials, laser welding portions (a shell welding portion (31) and a flange welding portion (32)) obtained by laser connection of the lower shell and the upper shell are formed, a lower flange portion (11c) is arranged around a side opening portion (10b) of the upper shell (11), an upper flange portion (12c) is arranged at a side of the upper shell (12), a cover side flange portion (20c) is arranged at a position of the cover opposite to a shell side flange portion (10c) formed by the lower flange portion and the upper flange portion, and an ultrasonic welding portion (33) is formed by ultrasonic connection of the shell side flange portion and the cover side flange portion.

Description

technical field [0001] The present invention relates to a small waterproof connector having waterproofness. Background technique [0002] A smartphone or the like has a connector into which an earphone or the like is plugged. Such connectors are required to be miniaturized and waterproof. [0003] Patent Document 1 discloses joining the lower case and the upper case by laser welding (Japanese original: fusion) (Japanese original: joining), and joining the case and an annular member by laser welding. [0004] Figure 10 It is a perspective view which shows the connector device 100 with a control function of patent document 1. like Figure 10 As shown, the joint cover 140 is inserted into the grooves 114 on three sides of the connector housing 112 to fill the recesses of the grooves 114 . The junction cover 140 is welded to the split casings 120 and 130 . [0005] The annular member 150 is externally fitted into the connector housing 112 so as to transversely cut the welde...
