Abstract: An accessory includes a case body, a cover unit, and first and second coupling units. The case body is formed with a receiving space for receiving a portable electronic device. The cover unit is configured to be coupled removably to the case body for closing and opening the receiving space. The first coupling unit includes a data and charge connector for mating electrical connection with a data and charge socket of the portable electronic device, and a data and charge port connected to the data and charge connector. The second coupling unit includes a connector jack for mating electrical connection with an audio socket of the portable electronic device, and an audio port connected to the connector jack.

Abstract: An accessory is for electrically connecting an audio output device to a portable electronic device. The accessory includes an attachment unit, a connector jack and a coupling unit. The attachment unit is to be removably attached to the portable electronic device. The connector jack is for mating electrical connection with an audio socket of the portable electronic device. The coupling unit is for mating electrical connection with the audio output device, and is to be removably attached to the attachment unit for establishing electrical connection with the attachment unit. The attachment unit and the coupling unit are configured to removably engage each other by magnetic attraction.

Abstract: An organizing device is for organizing multiple optical fiber lines to run parallel to each other on a plane. The organizing device includes a guiding unit and a positioning unit. The positioning unit includes a main body slidably disposed on the guiding unit, a first positioning part extending from the main body, and a second positioning part that extends from the main body in a same direction as the first positioning part and that is spaced apart from the first positioning part. The main body, the first positioning part and the second positioning part cooperate to define a positioning slot. The distance between the first and second positioning parts corresponds to a diameter of the optical fiber lines.
