Fiber optic adapter
The present invention belongs to an adapter, especially a fiber optic adapter, which is easy to assemble and disassemble, thereby facilitating heavy work, and avoids time-consuming and costly assembly methods such as ultrasonic welding in the assembly process, thereby improving assembly efficiency and improving adapter yield. .
The fiber optic adapter can be connected to two fiber optic cables, thereby extending the overall length of the fiber optic cable to facilitate fiber optic configuration.
U.S. Patent No. 6,431,762 discloses a fiber optic adapter that includes a housing, a sleeve retaining member, a sleeve, and a positioning member.
The outer casing is hollow and has an inner space, and a horizontal plate is formed in the inner space, and a first sleeve is formed on the horizontal plate. Further, a top surface of the outer casing is formed with a positioning groove. The sleeve fixing member is disposed in the outer casing, and a second sleeve is formed on the sleeve fixing member, and the first sleeve and the second sleeve are combined with each other to fix the sleeve to the first and second sleeves. in. In addition, a laterally projecting positioning projection is formed on the outer side of the sleeve fixing member, and the positioning projection abuts against the horizontal plate. The positioning element has a circular shape and has two positioning arms. The positioning arm penetrates into the positioning groove to jointly block the positioning protrusion with the horizontal plate, thereby fixing the sleeve fixing member in the outer casing.
However, this fiber optic adapter has many of the following disadvantages.
1. First, the structure in which the horizontal plate and the first sleeve are formed inside the outer casing makes the outer casing extremely complicated, and when the outer casing is manufactured by injection molding, the desired yield cannot be achieved, and thus the outer casing is expensive to manufacture.
2. The U-shaped positioning component has a small outer shape, and the assembly needs to be accurately aligned by the human eye to avoid skewing, thereby consuming assembly time. Due to its small size, it is difficult to exit once inserted into the positioning groove. When the fragile casing is accidentally damaged or damaged during assembly or use, the assembler or the consumer cannot easily disassemble the fiber adapter. If the parts are replaced or reorganized, and if the heavy work is easy to cause damage to the appearance of the outer casing, it is unfavorable for heavy work. Furthermore, the fiber adapter is fixed to the panel and an additional snap member is required.
In addition, there is another fiber optic adapter with front and rear housings, two sleeve fasteners, and a sleeve. The two sleeve fixing members respectively have a sleeve. After assembling the two sleeve fixing members and fixing the sleeve, the front and rear outer casings are assembled and clamped to the two sleeve members, and finally welded and welded in the ultrasonic wave fusion manner. shell. However, ultrasonic welding relies on extra power, energy costs, and the process is time consuming, so the cost is equally high. In addition, if the casing is used for aging or the rupture needs to be replaced in the future, the front and rear casings after ultrasonic welding cannot be disassembled and cannot be reworked. Furthermore, ultrasonic welding often has the problem of skewed appearance and burrs.
The creator has created a fiber optic adapter in view of the high cost of the existing fiber optic adapter, the time-consuming assembly, the unfavorable rework, and the like.
