Background technology

Along with being becoming tight global economy fast development, supply of electric power day, energy-conserving and environment-protective have become the fundamental state policy of countries in the world, under this overall background, the electronic energy-saving lamp industry is able to fast development, electricity-saving lamp is promoted and should be strengthened by the dynamics of usefulness, and traditional incandescent lamp bulb is replaced by electricity-saving lamp the sixth of the twelve Earthly Branches gradually; And the energy-saving lamp tube shape is varied at present, and fluorescent tube is exposed damaged by the external force effect, and also can't be satisfied with when installing for the preference of conventional bulb shape in household or office space, each electricity-saving lamp production firm develops various bulb-shaped electricity-saving lamps for this reason, but mostly do not make full use of the use in the space between fluorescent tube two pins, adopt two circuit boards in design, and need partly adopt special electronic devices and components, cause the volume of this bulb-shaped electricity-saving lamp bigger than normal, structure is complicated, production and assembly efficient is low, increased the production cost of electricity-saving lamp greatly, and do not resolve heat dissipation problem well, cause the electricity-saving lamp cost to increase and the lost of life.

The utility model content

For solving the existing problem of above-mentioned bulb-shaped electricity-saving lamp, the utility model is intended to propose that cost simple in structure is low, long, a kind of easily and fast bulb-shaped electricity-saving lamp of production and assembly of good life-span of thermal diffusivity.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of bulb-shaped electricity-saving lamp, contain fluorescent tube, two and half bulb-shaped case and lamp holders, it is characterized in that: the cover upper edge is provided with the bulge loop muscle in the pipe shape, the ring place is provided with the annular groove that fastens with the bulge loop muscle in the bulb-shaped case neck, interior cover both sides, lower edge are provided with the wing ring of two symmetries, be provided with two straight cutting grooves in the axial endless inner wall of interior cover corresponding with wing ring, straight cutting groove end is provided with the opening that is communicated with outer wall of inside race, circuit board inserts in the straight cutting groove, in being fixed in, two luminous tube pins insertion wing ring puts, the pin electrode is pressed to touch with the electrode contacts of circuit board and is connected, and lamp holder is electrically connected with circuit board and and bulb-shaped enclosure fastening riveted joint.

The bulge loop muscle that puts in the utility model is located at, wing ring and straight cutting groove and interior cover are one-body molded; Opening is that the electrode contacts of circuit board touches the connected entrance that is connected with pin electrode pressure.

The utility model beneficial effect is: put in realizing circuit board and fluorescent tube be fixed on by wing ring and straight cutting groove, the luminous tube pin electrode is pressed to touch with the electrode contacts of circuit board and is connected simultaneously, two and half bulb-shaped cases by the annular groove on it with in the bulge loop muscle that puts fasten, by lamp holder be electrically connected with circuit board and and bulb-shaped enclosure fasten riveted joint and form novel, this novel utilization makes full use of the space between luminous tube pin, the space of the circuit board of cover is utilized effectively in being inserted in, use two circuit boards that a circuit board substitutes to be needed in the original design, replace specific components by the conventional electrical components and parts, because its parts reach the cost that production and assembly reduce product fast and greatly less, and the space is left in the circuit board both sides in the interior cover of tubulose, the thermal diffusivity of whole lamp increases its useful life well, helps strengthening the competitiveness of product in market.

Embodiment S

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1, Fig. 6 and a kind of bulb-shaped electricity-saving lamp shown in Figure 7, form by fluorescent tube 1, two half bulb-shaped case 3, screw thread mouth lamp holder 2, interior cover 5 and the circuit boards 10 that can fasten; Cover 5 upper edges are provided with bulge loop muscle 6 in the pipe shape, the ring place is provided with the annular groove 4 that fastens with bulge loop muscle 6 in the bulb-shaped case neck, two and half bulb-shaped cases 3 are interlocked by annular groove on it 4 and bulge loop muscle 6 on the interior cover 5, and cover 5 is fixed by half bulb-shaped case 3 of two fastenings in making; Interior cover both sides, 5 lower edge are provided with the wing ring 7 of two symmetries, be provided with two straight cutting grooves 8 in the interior cover 5 axial endless inner wall corresponding with wing ring 7, circuit board 10 inserts in the straight cutting groove 8, straight cutting groove 8 bottoms are provided with the opening 9 that is communicated with interior cover 5 outer walls, two fluorescent tubes, 1 pin inserts wing ring 7 and is fixed on the interior cover 5, pin electrode 11 is pressed to touch with the electrode contacts of circuit board 10 and is connected, and opening 9 is pressed with pin electrode 11 for the electrode contacts of circuit board 10 and touched the connected entrance that is connected; Screw thread mouth lamp holder 2 is electrically connected with circuit board 10 and fastens riveted joint with two and half bulb-shaped enclosure 3; Bulge loop muscle 6 in the utility model is located on the cover 5, wing ring 7 and straight cutting groove 8 and interior cover 5 are one-body molded.

During assembling, earlier 1 two pins of fluorescent tube are inserted in the wing ring 7 of interior cover 5, pin electrode 11 is in the opening 9 at this moment, again circuit board 10 is inserted in the straight cutting groove 8 of interior cover 5, pin electrode 11 was pressed to touch with the electrode contacts of circuit board 10 and was connected this moment, two and half bulb-shaped cases 3 are fastened with interior cover 5, fluorescent tube 1 is in the two halves bulb-shaped case 3 formed spaces, screw thread mouth lamp holder 2 is electrically connected with circuit board 10, lamp holder 2 fastens riveted joint with bulb-shaped enclosure and finishes this novel assembling, can be thrown light in these novel screw thread mouth lamp holder 2 sources of Connecting Power.
