Abstract: A bulb set structure comprises a plug having two guiding pieces to connect with a power source and to assemble with a LED bulb set and a fitter, an orifice to output alternating current, and a power converting unit having one end to electrically connect with the guiding pieces, and having another end to connect with wires of the LED bulb set and the fitter by using the joining segment to convert the alternating current into direct current, and a circuit board is used to rectify the alternating current to output direct current to emit LED bulb set and to transmit the alternating current to the fitter.

Abstract: A waterproof structure for a transform plug of a socket includes a housing having a front receiving portion and a rear receiving portion spaced in a hollow exterior thereof by using a first and the second partition to receive a conducting pieces and a transforming unit respectively, and a waterproof layer is formed between outer rims of a back cover, a rear cover, and the housing to prevent water from permeation. In addition, a photo resistor and a transparent portion of the back cover are used to conduct the power source to a light string automatically based on lights, thus flashing light freely.

Abstract: A socket, plug, and adaptor combination includes a housing having a forward sliding door; an inverted L-shaped circuit assembly in the housing having a conductor mounting section in the vertical part; a transformer being concealed in the horizontal part of the circuit assembly in a waterproof way and adapted to electrically connect to a power cord; two electrical connection assemblies each disposed in the conductor mounting section and having a prong; a conductive assembly comprising two separate fuses disposed in the conductor mounting section, each fuse being electrically interconnected between the prong and the transformer; a cover releasably secured onto the circuit assembly and having two sockets distal the prongs; and a covering plate disposed between the transformer and the cover. The combination is applicable to be used as a charger for outdoor LED type Christmas light strings.

Abstract: Waterproof electric plug or receptacle for LED light string is provided. In one embodiment, the plug includes a housing comprising two prongs, two fuses, an internal space, rear passages, compartments between the space and the passages, a wall for separating the space and the compartments; an electrical assembly comprising a PCB electrically to the prongs via the fuses, and rear conductive posts in the compartments; a power cord passing the passages and having two sleeves secured to the posts, and a shell mounted around the housing. Waterproof adhesive is applied on the wall, the compartments, and front and rear ends of the PCB.

Abstract: An electrical adapter includes a housing comprising a front portion including two compartments and two front slits, and a rear portion including longitudinal slots and a damping section including two side cavities, and bottom channels; two blades each having a rear portion fastened in the slit and the compartment; a PCB in the housing and having a transformer unit; two conductive seats on a front end of the PCB, each seat being fastened in the compartment; elastically bent contacts mounted on a rear end of the PCB, the contact including a connecting surface and an axial central positioning groove on the connecting surface; and an electrical wire having its rear portion bent to pass the channel to fasten an end electrical terminal of either conductor thereof on the groove in the cavity and electrically connect same to the connecting surfaces.

Abstract: An improved waterproof socket adapter which consists of an insert holder, a housing, leaf copper conductors, a cover, a power cable and u shaped copper tabs et cetera, the insert holder has a waterproof partition and a key arranged inside it, and cord profiled grooves with ribs provided behind and between pinholes on its front side; the housing has internal sliding and guide slots provided for fitting a key on the cover and the waterproof partition inside the insert holder respectively, and a front key-way arranged for engaging the key on the insert holder; besides, a bottom gap is provided on the front side of the housing and in its vertical wall there are cord profiled grooves and a key-way provided, the cord profiled grooves have several ribs arranged in them respectively; for the key of the insert holder has its vertical extension integrated with the waterproof partition, two cords of the cable may be separated positively without any short circuit when the insert holder and the housing is assembled togeth

Abstract: An improved water-proof socket adapter design includes an insert holder, a housing, a power cable and leaf copper conductors, the insert holder has a waterproof partition in it and an extension at its end on which a division, cord grooves, sliding blocks and ribs are provided, when a power cable with leaf copper conductors is placed in the insert holder, outer insulators of the power cable will rest against the ribs, and will be clamped by ribs in the cord grooves of the housing when the insert holder is inserted into the housing, therefore, the power cable is fixed firmly in the cord grooves with its cords being separated by the division; the housing has guide slots, key ways and sliding slots provided in it, when the insert holder is inserted into the housing, its waterproof partition and the division and the sliding blocks on the extension are fitted just in the guide slots and the sliding slots respectively, therefore, the cords of the power cable may be separated positively without any short circuit prov

Abstract: An improved switch design with power cable locking capability. A lower housing has at one end of its internal sides a receptacle for a power cord fitting in it firmly. At its other internal side, a passage is provided between two deflectors for two ends of a sheared power cord, with each cord end being bent round in order to hold them in the receptacle firmly. Blade/leaf conductors are provided which have a convex end and an elastic design so that when the upper and the lower housings are assembled together, the convex end of the blade/leaf conductors will contact with the copper switching conductor on the switching wheel. The switch design provides reliable electrical conduction, prevents breakage and electrical leakage, and provides a secure electrical connection even in the case of an applied foreign force.

Abstract: An improved polarity fuse plug. The plug includes an outer shell, an inner plug, 2 electric conductors, a concave shaped butterfly plate and a water proof chip. The outer shell is a flat stand and the inner plug holds each electric conductor separately. One of the electric conductors is connected to the fuse and the end of the other electric conductor is connected to the power cable. There is a concave shaped flume on the side of the fuse box and inside of the box has the concave shaped butterfly plate plugged onto it. The end of the concave shaped butterfly plate is connected to the power cable so as to avoid exposing the power cable when the fuse box is opened. Inside the plug are 2 power cables and a cable separation boad installed in order to strengthen the insulation. Also both the outer shell and the inner plug that are facing each other have a convex slot in order to hold a water proof chip to prevent water leaking in and to prevent leakage of high voltage to secure safety.
