Detailed description of the invention
Referring to figs. 1 through Fig. 6, a kind of lamp string 1, comprise the continuous print leader cable 2 with predetermined length, described leader cable 2 comprises phase line, zero line and ground wire three bar insulation heart yearn 20, its first end is fixedly connected with public plug 28, the second end is fixedly connected with the female 29 that can mate with described public plug 28, so that many lamp string 1 head and the tail are connected in series; Multiple lamp socket assembly 3 be connected in parallel on leader cable 2, lamp socket assembly 3 described in each includes the secondary cable 30 with a predetermined length, and described lamp socket assembly 3 to be consisted of with leader cable 2 with predetermined spacing described secondary cable 30 to be mechanically connected and to be electrically connected; Described secondary cable 30 comprises phase line and zero line two bar insulation heart yearn, in junction, the relative two side portions ground of the conductor 21 of the insulation core wire 20 in described leader cable 2 is exposed, and the copper plug 32 of the insulation core wire end conductor connection of described secondary cable 30 runs through the rear bending of the conductor 21 exposed and is clamped on insulation core wire 20; Light source 33, is arranged in described multiple lamp socket assemblies 3; T connector 4, is fully coated on described secondary cable 30 and described leader cable 2 junction in the mode of injection mo(u)lding.
Usual leader cable 2 selects 3 core cables, contain respectively as zero line, the insulation core wire of phase line and ground wire, as the case may be, ground wire can not be configured, also many phase lines and zero line can be set, for improving water resistance and the security of lamp string 1 further, insulation core wire outside is coated with the protective overcoat 22 of insulative water-proof, strengthen durability and the applicability of lamp string, consider that lamp socket assembly 3 is suspended in below leader cable 2 by secondary cable 30, secondary cable 30 can select 2 core cables, so secondary cable is more flexible, lamp string can have more beautiful outward appearance, the light source 33 of its end can keep luminous with the direction perpendicular to ground.Leader cable 2 can select American Standard SJTW18AWG, 16AWG or 14AWG etc.
When injection mo(u)lding, by an injecting glue, by described secondary cable 30, fully coating efficiency is lower with described leader cable 2 junction, because the volume of T connector 4 is comparatively large, is difficult to quick hardening by cooling, the time of processing T type joint will be caused so longer.With reference to Fig. 7 and Fig. 8, as the further improvement of technology, be built-in with joint liner 40 in described T connector 4, described joint liner 40 is assembled by left and right side frame 401,402 and is put together, and described conductor 21 and copper plug 32 are all wrapped in described joint liner 40.So, can reduce the injecting glue amount of single, cooling velocity is obviously accelerated.Both ensure that cooling velocity like this, turn reduce and shrink in sizing material cooling procedure and cause outward appearance unsightly.
Further, the left frame 401 of described joint liner 40 is identical with the shape and structure of left side frame 402, simplifies production and the combination mutually of left and right side frame.For fixing the insulation core wire of major and minor cable further, left frame 401 is provided with the longitudinal wire casing 403 corresponding with the insulation core wire 20 of leader cable 2, and left frame 401 is provided with the horizontal wire casing 404 corresponding with the insulation core wire of secondary cable 30.
Described lamp socket assembly 3 comprises the screwed socket 34 holding light source 33, and is coated with the waterproof insulation shell 35 of soft material formation in described screwed socket 34 outside by insert injection molding mode.Adopt screwed socket to have to change that lamp is convenient, security better, firmly advantage is installed.Soft material makes waterproof insulation shell 35 not only good hand touch, also enhances the weather resistance of lamp string.With reference to Fig. 9, as the further improvement of technology, along the outer surface extending out to described light source 33, extension 36 forms interference fit with outer surface described in light source 33 at described waterproof insulation shell 35 end.After light source 33 is tightened, the shell of soft material will tightly be wrapped in the appearance of light source 33, plays the effect of water proof and dust proof further.
As required, as bulb number and power, leader cable 2 has predetermined length, and the secondary cable 30 of connecting lamp seat assembly 3 is evenly distributed on leader cable 2 at predetermined intervals.Preferred leader cable 2 about long 14.6 meters, lamp socket assembly 3 is evenly distributed on leader cable 2 with the spacing of about 0.6 meter, wherein about long 8 centimetres, secondary cable 30.In addition, in this embodiment, when adopting Unite States Standard, lamp socket assembly 3 adopts E26 standard lamp head interface, and when adopting European Standard Time, lamp socket assembly 3 adopts E27 standard lamp head interface, light source 33 uses incandescent lamp bulb, and each lamp socket assembly 3 all has the bearing capacity of at least 25W.Leader cable 2 two ends are fixedly connected with public plug 28 and female 29 respectively, when needing larger length, only many lamp string first places need be connected in series.For convenience of installing and fixing, described T connector 4 is provided with the hanger 42 of hanging wire, when length is larger, can be hung up by lamp string by hanger 42, reduces the pulling force that leader cable 2 is subject to, prevents mechanical failure.
With reference to Figure 10 to Figure 12, produce the process at lamp string of the present utility model, wherein Figure 10 is according to predetermined spacing, and on whole piece leader cable 2, compartment of terrain cuts the overcoat 22 with certain length, preferably 3 ~ 5cm, exposes insulation core wire 20 wherein; Figure 11 to Figure 12 divests insulating barrier by the mould of customization to the insulation core wire 20 exposed, and partly exposes conductor 21.The copper plug 32 of so secondary cable 30 end directly can contact with the conductor 21 of leader cable, by running through conductor 21 and bending formation mechanical connection and electrical connection.
These are only most preferred embodiment of the present utility model, is not to restriction of the present utility model.The adjustment carried out above embodiment according to design of the present utility model, amendment and combination all fall within protection domain of the present utility model.
