Abstract

The utility model discloses a festival lamp waterproof control box, comprising a box dochium, a box lid, a wire-pressed clip, a circuit board, electrical wires, bolts and an airproof ring, which is characterized in that the airproof ring, which is fixed between the box dochium and the box lid, is square and embedded in the groove which coils the meatus of the box lid. The salient coiling the meatus of the box lid is combined with the groove under the electrical wire at the export of the box dochium. The use of this structure makes integral seal from the electrical wire ejected from the circuit board to the export. And preceding sealant at the export forms bi-sealed export. Crosspiece is sealed with sealant which improves the anti-pull effect of the wire-pressed clip. So that the utility model will not only satisfy the demands of waterproof but also meet the request of anti-pull of the electrical wire. The utility model has the advantages of simple structure, low cost, good sealing performance, good anti-pull effect and so on.

Description

Holiday lamp is prevented water controller

Affiliated technical field

The utility model relates to ornament lamp accessory technical field in red-letter day, especially relates to the anti-water controller of a kind of Holiday lamp.

Background technology

Holiday lamp be celebrating red-letter day article commonly used, the Holiday lamp controller is a Holiday lamp electrical equipment control accessory.Controller comprises box, wiring board, Wire fastener and draws electric wire etc., and Holiday lamp is when outdoor application, and controller box must be made water-tight.Controller box generally make cassette holder, lid two halves again fixing seal be integral.Draw because of the Holiday lamp controller generally all can have many wires, the sealing at the electric wire place of drawing is a weak link, and it will reach in the requirement of experiment of drenching with rain; In addition, electric wire also will possess tensile property, reaches the tension code requirement.Prior art generally is to adopt the manual method that adds epoxy resin or silicone adhesive to solve waterproof problem, exists speed of production slow, the cost height, and color is inconsistent, and fluid sealant exposes the problems such as attractive in appearance that influence.

The utility model content

It is reliable that the technical problems to be solved in the utility model provides a kind of sealing simple in structure, and the anti-water controller of the Holiday lamp of electric wire tension.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of Holiday lamp is prevented water controller, comprise cassette holder, lid, Wire fastener, wiring board, electric wire, screw, sealing ring, it is characterized in that: described sealing ring is that integral body is " mouth " font, be arranged between cassette holder and the lid, be embedded in the groove around lid mouth end, projection around cassette holder mouth end cooperates with above-mentioned groove embedding, and electric wire has sealing strip in cassette holder electric wire exit.

As preferred described sealing ring with the electric wire contact position with the quantity of electric wire with profile phase should be shaped on half slot and cross section is a rectangle, be circular at all the other cross sections.

Be provided with groove as preferred cassette holder electric wire exit and wherein be embedded with rubber weather strip, sealing bar and electric wire contact position should be shaped on half slot with the quantity and the profile phase of electric wire, and its cross section is a rectangle.

As preferred in lid and cassette holder the Wire fastener inboard be provided with corresponding crosspiece, and scribble fluid sealant thereon.

As the spaced apart teeth that preferably is provided with mutual correspondence in lid crosspiece both sides and inboard, electric wire exit, and the quantity of neutral gear is identical with the electric wire radical between the spaced apart teeth.

As the preferred Wire fastener font that is that integral body is flat " returning ", upper and lower horizontal bar staggers mutually.

The beneficial effects of the utility model are: adopt said structure, just make the electric wire of drawing form integral sealing to the exit from circuit board, add sealing strip under the exit, the crosspiece place adds the fluid sealant sealing again, double sealing makes sealing more reliable, the tensile property of Wire fastener is further improved, make this controller not only satisfy waterproof requirement but also reached the requirement of electric wire tension.Advantages such as have simple in structurely, cost is low, and sealing, tension are effective.

The specific embodiment

As Fig. 1, shown in Figure 2, the utility model controller comprises cassette holder (9), lid (1), Wire fastener (8), wiring board (2), electric wire (6), screw (12), sealing ring (5), in lid (1) and cassette holder (9), be provided with corresponding crosspiece (3) between wiring board (2) and the Wire fastener (3), respectively lid (1) and cassette holder (9) inside are divided into two, one side is to place wiring board (2) opposite side to place Wire fastener (3), rubber seal (5) is that integral body is " mouth " font and is arranged between lid (1) and the cassette holder (9), sealing ring (5) is a rectangle at the cross section in electric wire (6) exit, is circular at all the other position cross sections.Sealing ring (5) is embedded in around in lid (1) mouthful groove of holding, and embeds with above-mentioned groove around cassette holder (9) mouthful projection of holding to cooperate; Be provided with groove in cassette holder (9) electric wire (6) exit and wherein be embedded with rubber weather strip (7), sealing bar (7) should be shaped on half slot with the quantity and the profile phase of the same electric wire in electric wire (6) contact position (6), and its cross section is a rectangle.Wire fastener (8) inboard is provided with corresponding crosspiece (3) in lid (1) and cassette holder (9), and at the preceding fluid sealant (10) that is coated with thereon of assembling electric wire (6), sealing glue (10) generally is epoxy resin or silicon rubber.Lid (1) crosspiece (3) both sides and electric wire (6) inboard, exit are provided with the spaced apart teeth (4) of mutual correspondence, and the quantity of neutral gear is identical with electric wire (6) radical between the spaced apart teeth (4).Electric wire (6) embeds the neutral gear that crosspiece (3) both sides spaced apart teeth (4) form from wiring board (2), reenter the neutral gear that the inboard spaced apart teeth in electric wire (6) exit (4) forms through Wire fastener (8), draw along exit sealing ring (5) half slot, electric wire (6) the mistake dress that both on your marks in reduce installing like this, again because and between the spaced apart teeth (4) friction increased stretching resistance.

Screw hole and head of screw hole are located at the four corners position of controller box, screw hole is located in the lid (1), in cassette holder (9), be provided with the head of screw hole corresponding with screw hole, by screw (12) lid (1) and cassette holder (7) are fixed into one, above-mentioned head of screw hole can make screw head buried in the head of screw hole more deeply, fill in friction tight tubbiness plug (11) more inwardly from the head of screw aperture, bung is blocked the head of screw aperture inwardly, and makes the breech face and the same plane of cassette holder (9) outer surface of plug (11); For keeping unified, the material of plug (11), color are all identical with cassette holder (9).

As shown in Figure 3, Figure 4, Wire fastener (8) is flat " returning " font for integral body, and upper and lower horizontal bar staggers mutually.Like this, electric wire just is " S " shape after passing Wire fastener (8), and the tension effect further promotes.
