Description

Show the simple encapsulating structure of lamp string

Technical field

The utility model relates to a kind of festoon lighting structure, especially a kind of encapsulating structure for showing lamp string.

Background technique

Lamp string be widely applied to it is various illumination or decoration occasions in, can be distributed along moulder outer profile to be formed it is luminous Three-dimensional contouring can also will form the display matrix of a large-scale two dimension or three-dimensional after multiple lamp string proper alignments.Lamp string one As concatenated using the control circuit for being loaded with LED display point, since the issued light of LED display point is more concentrated and brightness It is higher, for make each of lamp string can LED display point can uniformly light-emitting formed luminescent ball, generally require outside control circuit Encapsulate lampshade.On the one hand LED being shown to, the light of point is scattered to form luminescent ball, another aspect lampshade can be effective It can be realized waterproof etc. when the components, especially outdoor application such as protection LED display point and control circuit, avoid the damage of lamp string. But the encapsulation of lampshade and its internal element is general by the way of encapsulating at present, although having preferable waterproof effect, It is difficult to repair replacement after damage.It is concatenated between control circuit by route additionally, due to for connecting, route is in addition to needing to be responsible for The gravity of entire lamp string is also undertaken outside transmission signal, and between route and control circuit is the pad by being welded and fixed It being difficult to ensure and enough bonding strengths is provided, the lamp string having thus also needs to assist having tensile steel wire to undertake the gravity of lamp string, The installation complexity of lamp string is caused to increase.

Summary of the invention

In view of the above shortcomings of the prior art, the utility model provide it is a kind of show lamp string simple encapsulating structure, one Aspect can simplify the installation of lampshade, while can be improved the bonding strength between route and lampshade, to reduce to welding position Stress, keep the overall structure of lamp string stronger reliable.

Show the simple encapsulating structure of lamp string, the display lamp string is at least made of the control circuit of multiple concatenations, adjacent By control route concatenation between control circuit, it is equipped with display point in control circuit, has cover for encapsulation by control circuit Wherein, the cover is made of package the two sub- covers mutually fastened, extending direction of the sub- cover along control route Equipped with the wire casing for fixed control route, the diameter of wire casing is less than the outer diameter of the electric wire of control route, the wire casing after fastening with The electric wire of control circuit is interference fitted.

Wherein, the annular convex rib for clamping control route is additionally provided in the wire casing, after cover fastens, annular convex rib is embedding Enter into the insulation sheath of electric wire.

Wherein, the annular convex rib in each wire casing is two groups or more, along control route extending direction distribution.

Wherein, the section of the convex ribs is triangular in shape.

Wherein, it is respectively equipped with mutually matched positioning ring at the fastening of described two sub- covers, uses ultrasonic wave at fastening Heat seal.

Wherein, the wire casing position is additionally provided with two sub- cover positioning and tentatively fixed preload fastener comprising The plug connector and inserting groove of interference fit.

The utility model has the beneficial effects that after two sub- covers fasten, wire casing also will control route be clipped on wherein, by In between the two using interference fit, can make lamp string stress be by cover and control route between transmitted, and Welding position between control route and control circuit can't bear the gravity of lamp string, to guarantee the reliability of connection, prevent Only rosin joint or desoldering and lead to the failure of lamp string.

Detailed description of the invention

The present invention will be further described with reference to the accompanying drawing:

Fig. 1 is the broken away view of the utility model.

In figure, 1. control circuits, 2. control routes, 3,4. sub- covers, 5. wire casings, 6. annular convex ribs, 7. positioning Ring, 8. plug connectors, 9. inserting grooves.

Specific embodiment

As shown in Figure 1, the simple encapsulating structure of display lamp string, the display lamp string is at least by the control circuit of multiple concatenations 1 forms, and is concatenated between neighboring control circuitry 1 by control route 2, is equipped in control circuit 1 and shows point, there is the cover for encapsulation Body wraps up control circuit 1 wherein, and the cover is made of two mutually fastened sub- covers 3,4, sub- 3,4 edge of cover The extending direction for controlling route 2 is equipped with for the fixed wire casing 5 for controlling route 2, and the diameter of wire casing 5 is less than the electricity of control route 2 The electric wire of the outer diameter of line, wire casing 5 and control circuit 1 after fastening is interference fitted.After two sub- covers 3,4 fasten, wire casing 5 Will control route 2 be clipped on wherein, due between the two using interference fit, can make lamp string stress be by cover with It is transmitted between control route 2, and the weight of lamp string can't be born by controlling the welding position between route 2 and control circuit 1 Power prevents rosin joint or desoldering and leads to the failure of lamp string to guarantee the reliability of connection.

To keep the connection between wire casing 5 and control route 2 relatively reliable, it is additionally provided in the wire casing 5 and is controlled for clamping The annular convex rib 6 of route 2, after cover fastens, annular convex rib 6 is embedded into the insulation sheath of electric wire, further improves control Tensile strength between route 2 and cover.Moreover, the annular convex rib 6 in each wire casing 5 is two groups or more, along control route 2 Extending direction distribution.In addition, the section of annular convex rib 6 additionally uses triangular structure, annular convex rib 6 is engaged very well To the insulation sheath of electric wire, except it is above-mentioned play improve tensile strength in addition to, can also realize preferable waterproof effect.

Supersonic thermal setting is used at fastening between two sub- covers 3,4, for can before supersonic thermal setting convenient for the two It is accurately aligned, mutually matched positioning ring 7 is respectively equipped at fastening.After supersonic thermal setting, fuse into one at fastening, energy Enough play good waterproofing protection effect.

In addition to the further preliminary fixation before cooperation supersonic thermal setting, 5 position of wire casing is additionally provided with two sons The positioning of cover 3,4 and tentatively fixed preload fastener comprising the plug connector 8 and inserting groove 9 of interference fit, same interference are matched The preload fastener of conjunction prevents two sub- covers 3,4 from loosening before heat seal, carries out convenient for lamp string restocking into supersonic heat-conglutinating machine Heat seal.
