Abstract: A male connector is used to plug in a female connector defining a plugging hole and a positioning slot and includes an outer shell, a plug-in portion and a plurality of conductors inserted into the plug-in portion. The plug-in portion has a first outer periphery, a second outer periphery smaller than the first outer periphery, a positioning structure arranged on the first outer periphery, and a ring flange arranged on the second outer periphery. The first outer periphery is located between the outer shell and the second outer periphery. When the male connector plugs in the female connector, the plug-in portion and at least part of the conductors are accommodated in the plugging hole, the positioning structure is fixed to the positioning slot, the ring flange elastically bends toward the outer shell and elastically abuts against an inner wall of the plugging hole to improve waterproof effect.

Abstract: An electrical connector includes a connector body, a movable annular collar, and an elastic locking member. The connector body includes a plug and a peripheral wall enclosing the plug. A plurality of hollow openings are defined on the peripheral wall. The movable annular collar is movably sleeved around the peripheral wall. The movable annular collar includes abutting blocks, pressing blocks, and grooves. The elastic locking member is positioned between the peripheral wall and the movable annular collar. The elastic locking member includes a ring arranged around the peripheral wall, a plurality of elastic locking arms, and a plurality of push-out ribs. The end of each elastic locking arm is positioned in a hollow opening and is pressed by the pressing block or positioned opposite the groove. The abutting blocks abut against the lower portions of the push-out ribs.

Abstract: A magnetic waterproof connection device having a first connector and a second connector is provided. The first connector has a first connecting body, a first terminal seat, and a first plug-in portion having a plugging end. A first terminal and a first magnetic member are arranged in the first terminal seat. The second connector has a second connecting body, a second terminal seat, and a second plug-in portion corresponding to the plugging end. A second terminal and a second magnetic member are arranged in the second terminal seat. An annular sealing structure is arranged outside the second plug-in portion. An internal wall of the plugging end is tapered. The annular sealing structure has a first sealing ring and a second sealing ring pressing on the internal wall of the plugging end.

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.
