Abstract: A coupling structure of a cable connector includes a first connection head and a second connection head. The first connection head includes a first joint part, multiple insertion terminals, and an external threaded portion disposed on the first joint part. The second connection head includes a second joint part, multiple insertion holes, a fastening sleeve, a socket formed between the fastening sleeve and the second joint part, a positioning ring receiving the fastening sleeve, a plurality of fastening elements arranged between the positioning ring and the fastening sleeve, and a quick-release fastening ring. The quick-release fastening ring rotatably presses on the fastening elements. An internal threaded portion of each fastening element is engaged with the external threaded portion. Therefore, the first connection head and the second connection head can be securely fastened to each other and can be quickly detached from each other.

Abstract: A docking structure of a push-and-lock electrical connector includes a first connector, a second connector, and a locking part used to lock the first and second connectors. The locking part has at least one flexible locking arm having a locking portion and a latching block extending from the locking portion and protruding into the mouth of the second connector. An elastic spacing is formed between the latching block and the flexible locking arm. Thus, when the first connector is inserted into the mouth of the second connector, the latching block is latched in the latch groove of the first connector and an inner wall of the sliding shell sleeved around the second connector is pressed against the locking portion.

Abstract: A solar-powered temperature measuring apparatus includes: a case, at least one part of a surface thereof including a solar panel used for converting visible light to electric energy; a first connection portion, positioned in the case; and a temperature measurer, accepted in the case, including: a main body; a second connection portion, positioned on the main body and used for connecting with the first connection portion; and a charging element, connected electrically to the second connection portion and used for storing electric energy generated form the solar panel. By this means, visible light is converted to electric energy to conform to each country's current environmental protection policies, and the charging element may be charged at any time to solve the problem of a conventional clinical thermometer being unable to be used due to insufficient cell power.
