Description
Technical field
The utility model relates to a kind of light fixture, particularly relates to a kind of the have electricity-saving lamp of exempting from the blowtorch head or the light fixture of LED lamp.
Background technology
Light fixture is indispensable a kind of daily necessities in people's daily life, and light fixture both can be used as illumination usefulness, also can be used as to decorate to use.Traditional light fixture mostly is an incandescent lamp, and still, the light efficiency of incandescent lamp is low, useful life short, thereby has restricted the use of incandescent lamp.Existing light fixture is electricity-saving lamp or LED lamp mostly, no matter is electricity-saving lamp or LED lamp, all includes lamp holder and bonnet usually; Lamp holder is used for being connected in lamp socket; Be connected to power supply signal on the light source of light fixture, therefore, need be provided with the two poles of the earth that are used for connecting power supply signal on the lamp holder lamp socket.Prior art a kind of has the light fixture of exempting from the blowtorch head; Of Fig. 1; This light fixture (E26, E27 specification) it comprise one be used for realizing the metal cap 1 that contacts with the top power supply ', a lamp holder a 2 ' and bonnet 3 '; Metal cap 1 ' be fixed on lamp holder 2 ' crown center, lamp holder 2 ' bottom and bonnet 3 ' be connected fix bonnet 3 ' the be generally structural member that the injection moulding mode is processed; Lamp holder 2 ' then by metalwork 21 ' with working of plastics 22 ' constitute; And the metalwork 21 of lamp holder ' and working of plastics 22 ' between be to adopt the injection moulding mode to link together, promptly adopt injection molding way let working of plastics 22 ' be molded over metalwork 21 ' on, the metalwork 21 of lamp holder ' be used for realizing contacting with the side power supply; Working of plastics 22 ' be provided with through wires hole; Metal cap 1 ' be engaged in this through wires hole, metal cap 1 ' electrode of formation is connected with being used in the light fixture that lead is connected in the power supply of light source; Metalwork 21 ' another electrode of formation, the mains side lead that is connected light source with being used in the light fixture is connected; Metal cap 1 ' and metalwork 21 ' between then isolate by working of plastics 22 ' insulation.This structure have a light fixture of exempting from the blowtorch head; Because the metalwork and the working of plastics of lamp holder will be injection-moulded in together, therefore, the shortcoming of existence is: need the injection moulding of repetition; The concentricity of the lamp cap plastic parts that injection moulding is come out and the metalwork of lamp holder is not enough, and the cost cost is too high.
The utility model content
The purpose of the utility model is to overcome the deficiency of prior art; A kind of light fixture of exempting from the blowtorch head that has is provided, and is that working of plastics and the bonnet with lamp holder is injection molded into an integral body, and through the architecture advances to metalwork realize and lamp cap plastic parts and bonnet between fix; Like this; On the one hand, can avoid repetition injection moulding, really accomplish energy-saving and emission-reduction lamp cap plastic parts; On the other hand, also can reduce the lamp holder cost, on concentricity, also can accomplish unanimity, make things convenient for LED lamp and electricity-saving lamp intermediate power supplies line when assembling to pass.
The utility model solves the technical scheme that its technical problem adopted: a kind of have a light fixture of exempting from the blowtorch head, comprises metal cap, lamp cap plastic parts, lamp holder metalwork and bonnet; The crown center of lamp cap plastic parts is provided with the through wires hole that lead passes in the power supply that can let interior being used for of light fixture connect light source; Said metal cap is engaged in this through wires hole; Between lamp cap plastic parts and the bonnet through at least two plastic ribs formula structure that links into an integrated entity; Said lamp holder metalwork is socketed in the outside of lamp cap plastic parts.
The end section of the through wires hole of described lamp cap plastic parts is made as bellmouth.
Described bellmouth is gradually from bottom to top and dwindles.
The top of described lamp cap plastic parts, by through wires hole, the holding tank that is provided with to lower recess is contained in wherein with middle lead bending long after will passing through wires hole.
Described lamp holder metalwork is a penetrating shell-type structure up and down, and the upper end of this lamp holder metalwork is provided with the inwardly baby hem of bending downwards.
The end of described baby hem is along being provided with profile of tooth end limit.
The outside of described lamp cap plastic parts along horizontal direction be equipped with one be used for letting the baby hem of lamp holder metalwork embed caulking groove.
Described lamp holder metalwork is provided with first helicitic texture, and described bonnet is provided with second helicitic texture, and the bottom of lamp holder metalwork is coated on the outside at the top of bonnet, and first helicitic texture of lamp holder metalwork spins with second helicitic texture of bonnet and matches.
The bottom of said lamp holder metalwork is coated on the outside at the top of bonnet, and contacted part fixes through the riveting mode between lamp holder metalwork and the bonnet.
The utility model a kind of has the light fixture of exempting from the blowtorch head; Be that bonnet with lamp cap plastic parts and light fixture (like electricity-saving lamp or LED) connects injection moulding through two or more plastic ribs and comes out, the bonnet of lamp cap plastic parts and light fixture (like electricity-saving lamp or LED) has formed an integral body.The inner through wires hole that forms a taper of lamp cap plastic parts, such structure makes things convenient for passing of power lead (lead promptly).In addition, can ensconce the longer direct bending of the end of a thread in the groove in the other structure of making a groove of the through wires hole at the top of lamp cap plastic parts.The lamp holder metalwork is then made an integral body, and the inwardly downwards bending and form baby hem of limit, upper end can be strengthened the intensity of lamp holder metalwork like this, and with the frictional force of lamp cap plastic parts.
The beneficial effect of the utility model is, owing to adopted metal cap, lamp cap plastic parts, lamp holder metalwork and bonnet to form the part-structure with the light fixture of exempting from the blowtorch head; And the crown center of lamp cap plastic parts is provided with the through wires hole that lead passes in the power supply that can let interior being used for of light fixture connect light source; Said metal cap is engaged in this through wires hole; Between lamp cap plastic parts and the bonnet through at least two plastic ribs formula structure that links into an integrated entity; Said lamp holder metalwork is socketed in the outside of lamp cap plastic parts.This structure on the one hand, can be avoided the repetition injection moulding to lamp cap plastic parts, really accomplishes energy-saving and emission-reduction; On the other hand, also can reduce the lamp holder cost, on concentricity, also can accomplish unanimity, make things convenient for LED lamp and electricity-saving lamp intermediate power supplies line when assembling to pass.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain; But the utility model a kind of has the light fixture of exempting from the blowtorch head is not limited to embodiment.
