Fig. 1 is the cutaway view of the electric inlay device of mistake of the present invention;
Fig. 2 is the top view of the electric inlay device of mistake of the present invention;
Fig. 3 is the stereogram of the electric inlay device of mistake of the present invention.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1, Fig. 2 and Fig. 3 are respectively cutaway view, top view and the stereograms of the electric inlay device 100 of mistake of the present invention.Referring to figs. 1 through Fig. 3, this crosses electric inlay device 100 for the power supply of flame-proof type light fixture is imported to light-source chamber from wire connection cavity.In the present invention, light-source chamber chamber wall 200 and the wire connection cavity chamber wall 300 of flame-proof type light fixture are chamber independent of each other walls, only show a part for these two chamber walls in Fig. 1.In Fig. 1, wall more than 200 part in light-source chamber chamber is light-source chamber, and for the assemblies such as illuminating part are installed, the part of wire connection cavity chamber wall below 300 is wire connection cavity, for connecting power input.
Crossing electric inlay device 100 comprises injection moulding colloid 101, is closely enclosed in the inserts shell 102 of injection moulding colloid 101 outsides and the conducting strip 103 that passes injection moulding colloid 101.Wherein inserts shell 102 is made by metal or plastic cement, is roughly hollow cylindrical.On the outer peripheral face of inserts shell 102, be provided with outstanding back-up ring 104, this ring washer 104 is positioned at the middle part of inserts shell 102.
On the top of inserts shell 102, be provided with external screw thread 105, in the wherein one of light-source chamber chamber wall 200 and wire connection cavity chamber wall 300, be provided with the internal thread coordinating with it, in a preferred embodiment of the invention, on light-source chamber chamber wall 200, be provided with internal thread 201.In the wherein another one of light-source chamber chamber wall 200 and wire connection cavity chamber wall 300, be provided with through hole, in a preferred embodiment of the invention, on wire connection cavity chamber wall 300, be provided with through hole 301.The diameter of this through hole 301 is greater than the lower diameter of inserts shell 102.The top of inserts shell 102 is fixed on light-source chamber chamber wall 200 by screw thread, and bottom is by the through hole 301 on wire connection cavity chamber wall 300.
After installing, the back-up ring 104 of inserts shell 102 is between light-source chamber chamber wall 200 and wire connection cavity chamber wall 300, and upper surface posts on light-source chamber chamber wall 200, and lower surface posts on wire connection cavity chamber wall 300.After the lower casing at the upper casing at light-source chamber place and wire connection cavity place is fastenedly connected by screw etc., made electric inlay device 100 location.Because the connected mode of the upper casing at light-source chamber place and the lower casing at wire connection cavity place is prior art, do not repeat them here.In order to ensure sealing, carrying out IP protection, in a preferred embodiment of the invention, on the surface that light-source chamber chamber wall 200, wire connection cavity chamber wall 300 and back-up ring 104 post, be respectively arranged with sealing ring holding tank 202,302, be wherein equipped with sealing ring 400.
Injection moulding colloid 101 extends to wire connection cavity from light-source chamber, and by interior injection molded to inserts shell 102, comprises the main body 111 of closely being surrounded by inserts shell 101 and the backstop connecting portion 106 that is positioned at main body 111 two ends.This main body 111 is cylindric, and its height is identical with the height of inserts shell 102, and with two holes 112 that hold conducting strip 103.Backstop connecting portion 106 is cylindric, and its external diameter is greater than the external diameter of main body 111.Between two backstop connecting portions 106 and main body 111, form respectively step surface 107, step surface 107 adheres on top and the bottom of inserts shell 102.This step surface 107 can prevent that injection moulding colloid 101 from relatively moving with respect to the axial of inserts shell 102.On the outer peripheral face of main body 111, be provided with a plurality of anti-rotation lug bosses 108.By processing corresponding recess on the inwall at inserts shell 102, after injection moulding, just can in main body 111, form this anti-rotation lug boss 108.The shape of anti-rotation lug boss 108 can be small convex pillar, triangle, screw thread etc., with this, can prevent that injection moulding colloid 101 from relatively rotating with respect to inserts shell 102.
Whole main body 111 is run through in hole 112, and conducting strip 103 is extended in another backstop connecting portion 106 by main body 111 from a backstop connecting portion 106.On conducting strip 103, be provided with wiring hole 109.Preferably, conducting strip 103 is interior outstanding from backstop connecting portion 106 a little, so that wiring.For reinforced insulation, on injection moulding colloid 101, be also provided with two insulation boards 110, this insulation board 110 extends to respectively in two backstop connecting portions 106 from main body 111, and two conducting strips 103 are separated.Preferably, this insulation board 110 is along the radially extension of backstop connecting portion 106, thereby the inner space of backstop connecting portion 106 is divided into two parts.
Conducting strip 103, with after connector with wire is connected, can be communicated with to light-source chamber and wire connection cavity, can realize two chambeies and cross Electricity Functional.It should be noted that, only showed in the drawings the situation that electric inlay device 100 comprises two conducting strips 103, but the quantity of conducting strip 103 can be also a plurality of, for example three.Now the quantity of hole 112 and insulation board 110 can corresponding be set.
During manufacture, make conducting strip 103 and inserts shell 102 location, and adopt relevant mold injection.
The electric inlay device 100 of this mistake is not the situation that belongs to a chamber wall applicable to the chamber wall of light-source chamber and wire connection cavity, and meets the related request of coal peace authentication, can use on the compact light fixture of internal structure, to save space.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
