Abstract: The present invention provides a terminal electrical connector, which includes a terminal unit and a rotating cap. The terminal unit includes a terminal unit body, one or a plurality of electrical terminals provided inside the terminal unit body, and a torsion spring positioned on the terminal unit body. A limiting groove for limiting a pivotal stroke and a first positioning groove for positioning a first end of the torsion spring are provided on an outer peripheral side of the terminal unit body. The rotating cap includes a cap body, and one or a plurality of locking blocks provided on the cap body for locking on another terminal electrical connector. A sliding block and a second positioning groove are provided on an inner circumference of the cap body. The sliding block is used for limiting the pivotal stroke of the rotating cap relative to the terminal unit body, and the torsion spring is used for inertially returning the rotating cap to a position of a reset angle relative to the terminal unit body.

Abstract: A LED module with fast disassembly function is capable of being disassembled from a hole of a substrate by a tool and includes a lamp base, a LED and fasteners. The lamp base has tabs extending outwards. Each of the tabs is provided with a through-hole corresponding to the hole. The tab is formed with an inclined surface at the periphery of the through-hole. The LED is fixed on the lamp base. Each of the fasteners has a cap. The fastener is disposed through the hole and the through-hole to be fixed thereto. A notch is formed between the cap and the inclined surface. The tool is disposed in the notch to thereby disassemble the fastener from the hole and the through-hole. With this arrangement, the damaged LED can be detached from the substrate rapidly without replacing the whole LED module, thereby reducing the time and cost for maintenance.

Abstract: In a waterproof connector and a method for the same, the waterproof connector includes a plurality of electrically conductive terminals, an electrically insulating base, an electrical wire, a hollow cylinder and a cladding. The electrically insulating base has a receiving section. The electrical wire has a plurality of cores. Each core is connected to one end of each electrically conductive terminal. The hollow cylinder is connected to the receiving section and located to one side of the electrical wire. The cladding is used to cover the receiving section, the hollow cylinder, the core and one end of electrically conductive terminal. Further, the present invention provides a method for manufacturing the waterproof connector so as to enhance the yield rate and prevent the penetration of moisture.

Abstract: A loose-proof connector includes a screwing sleeve and a connecting body. The screwing sleeve is an annular body and has a circular through hole. The inner wall of the circular through hole is provided with a plurality of recessed arcs that are arranged circumferentially. The connecting body is inserted into the circular through hole of the screwing sleeve. An annular band of the connecting body is provided with protruding arcs to correspond to each recessed arc. The protruding arcs oppose to the any one of the recessed arcs and thus are adjacent thereto. Via this arrangement, the protruding arcs can bounce between any two adjacent recessed arcs, thereby generating a locking effect, and thus the loose-proof effect can be surely achieved.

Abstract: A waterproof device for an electrical connector includes a sleeve for containing a plug at front end thereof and having a resilient tightening section at another end thereof. A waterproof element is arranged in the resilient tightening section. A bolting cap is arranged on the outer end of the sleeve and tightens a peripheral of the waterproof element. Therefore, the waterproof element also tightens a cable of the plug. Therefore, the waterproof element wraps or caps one end of the cable and is compressed by the bolting cap to quickly assemble the waterproof device.

Abstract: A waterproof structure applied to an alternating current plug and an alternating current socket includes a plug body and a socket body. The plug body has an inserting portion, a covering portion formed thereon, a limiting portion formed between the plug body and the covering portion, and a washer positioned at one end of the limiting portion to be adjacent to the inserting portion. The socket body has an opening relative to the inserting portion for insertion, and a receiving portion formed thereon suitable for the covering portion to be engaged. The structure will not only be more stable than before to prevent separation occurred by an external force, but also be waterproof equally.

Abstract: An adjustable locking device includes a main body, at least a link structure, and at least a buckling device. The main body includes a connection portion. The connection portion provides one end of the link structure to connect thereon. The link structure includes a link element and an adjusting element connected to the link element. The link element provides a buckling device to pivotally connect thereon. The buckling device includes an actuating element and a buckling element. The actuating element and the buckling element are mutually connected, whereby the link structure can be moved within the connection portion of the main body, so as to change the position of the buckling device. The connection tightness between the main body and the connection port is thus enhanced.

Abstract: A housing structure of a connector having a plurality of parallel terminal channels formed on two lateral sides and separated from each other by ribs. A central portion of the housing is recessed to form a hollow section. The periphery of the hollow section is formed with a spacing section for separating the hollow section from the respective terminal channels and ribs. At least one central rib is longitudinally formed in the hollow section. Two sides of the central rib are formed with multiple laterally extending reinforcing ribs opposite to each other. The reinforcing ribs connect the central rib with the spacing section. An end section of each reinforcing rib connecting with the spacing section is tapered to form a narrowed section.

Abstract: Housing structure of a burn-in socket. Multiple densely and parallelly arranged core pins are respectively disposed the mold of the housing on two sides thereof. At least one filling member is plugged between the core pins. After molded, two lateral sides of the housing are formed with multiple densely arranged terminal channels separated from each other by ribs. A middle portion of each rib is formed with at least one notch. By means of plugging the filling member between the core pins, the rigidity of the core pins is enhanced to prevent the core pins from being bent and deformed so as to ensure precise width of the terminal channels and thickness of the ribs and thus ensure good quality of the product. Moreover, the flowability of the injected material flowing into the fine gaps between the core pins can be enhanced. Also, the injection pressure can be reduced to minimize damage of the mold.
