Abstract
The utility model discloses a wire outgoing structure for waterproof fans, comprising a fan frame, a circuit board provided with a fan in the fan frame, an annular U-shaped slot provided on the bottom end face of the fan frame, a seal ring provided in the U-shaped slot and a waterproof cover, wherein the waterproof cover is fixedly connected with the fan frame via the seal ring and is a drum whose one end is enclosed and side wall of outer contour is protruded outward with a transverse tube, a sleeve is sheathed on the transverse tube, the wire of the circuit board is leaded out from the transverse tube and the sleeve. Since the side wall of the waterproof cover is provided with a transverse tube for leading out the wires of the circuit board, the seal ring can realize seal by the whole ring, having good seal effect, strong operability, reduced error seal ratio and reduced breakdown rate. The outer surface of the transverse tube is provided with a plurality of flip rings for tightly connecting the sleeve to prevent water.
Description
Technical field
The utility model relates to drip-proof fan, is specifically related to a kind of lead outlet structure of drip-proof fan.
Background technique
The sealing configuration of the derivation line of drip-proof fan is particularly important, if sealing is improper, the circuit part very easily short circuit of intaking, thereby cause fan to burn the problem of deadlock to death, current practice is that lead directly comes out in the groove offered of fan frame, seal described fan frame by lower cover, be aided with methods such as seal ring or waterproof gasket cement, but these ways are owing to lower cover contacts with lead at the groove place that the fan frame is offered with the seal ring of fanning between the frame, form whole circle sealing, the sealing that causes whole fan easily is improper and lost efficacy.
The model utility content
The utility model purpose is: overcome the defective of prior art, provide a kind of seal ring that can allow form whole circle sealing, reduce the lead outlet structure of the drip-proof fan of rate of breakdown.
The technological scheme that model utility provides is as follows: a kind of lead outlet structure of drip-proof fan, include the fan frame, fan frame inside is equiped with the circuit board of fan, the bottom end face of fan frame has the u shape groove of an annular, in the u shape groove seal ring is installed, also include a waterproof lid, the waterproof lid is fixedly connected on the described fan frame by described seal ring, described waterproof lid is a drum of holding sealing one by one, its external frame sidewall is protruding a transverse conduit, the transverse conduit outer surface is socketed with a sleeve pipe, and the lead of described circuit board is drawn from described transverse conduit and sleeve pipe.
As preferably, in the lead outlet structure of above-mentioned drip-proof fan, the external frame edge of described waterproof lid is protruding several limits buttons, and described fan frame inwall is provided with the card post, described limit button and the clamping mutually of card post.
As preferably, in the lead outlet structure of above-mentioned drip-proof fan, the wall thickness of the external frame sidewall of described waterproof lid is slightly less than or equals the thickness of described u shape groove.
As preferably, in the lead outlet structure of above-mentioned drip-proof fan, the outer surface of described transverse conduit has several and helps closely being connected back-off ring with waterproof with described sleeve pipe, and the back-off ring is along the axially-aligned of described transverse conduit.
The utlity model has following advantage: in the sidewall of waterproof lid, offer transverse conduit, from transverse conduit, draw the lead of circuit board, make seal ring can realize whole circle sealing, good sealing effect, workable, the difficult problem improperly that seals has reduced rate of breakdown; Have several at the outer surface of described transverse conduit and help closely being connected back-off ring with waterproof with described sleeve pipe, simplicity of design, good sealing effect, waterproof sealing lid and described fan frame adopt the limit to buckle and block post and be connected, and be simple to operate.
Description of drawings
Fig. 1 is that the utility model is faced generalized section;
Fig. 2 is the schematic perspective view of waterproof lid 5 among Fig. 1;
Fig. 3 is the view of installing and using of the present utility model.
Embodiment
Below in conjunction with accompanying drawing concrete mode of execution is illustrated:
As depicted in figs. 1 and 2, a kind of lead outlet structure of drip-proof fan, include fan frame 1, fan frame 1 inside is equiped with the circuit board 2 of fan, the bottom end face of fan frame 1 has the u shape groove 3 of an annular, one seal ring 4 is installed in the u shape groove 3, also includes a waterproof lid 5, waterproof lid 5 is fixedly connected on the described fan frame 1 by described seal ring 4; Described waterproof lid 5 is drums of holding sealing one by one, the wall thickness of the external frame sidewall of described waterproof lid 5 is slightly less than the thickness of described u shape groove 3, its external frame sidewall is protruding a transverse conduit 6, transverse conduit 6 outer surfaces are socketed with a sleeve pipe 7, the lead 8 of described circuit board 2 is drawn from described transverse conduit 6 and sleeve pipe 7, the outer surface of described transverse conduit 6 has Three Favorables and the described sleeve pipe 7 tight back-off rings 61 that are connected with waterproof, and back-off ring 61 is along the axially-aligned of described transverse conduit 6.
The external frame edge of described waterproof lid 5 is protruding to have four limits to detain 51, and described fan frame 1 inwall is provided with four card posts 11, described limit button 51 and the clamping mutually of card post 11.
During installation, as shown in Figure 3, install described circuit board earlier in fan frame 1 inside, be inserted in seal ring 4 in described u shape groove 3 the insides, then the lead 8 of described circuit board is penetrated in the described transverse conduit 6, sidewall with waterproof lid 5 tightly is pressed into described seal ring 4 in the described u shape groove 3 afterwards, utilize limit button 51 on the waterproof lid 5 and the card post 11 on the described fan frame 1, waterproof lid 5 and described fan frame 1 are sealed, afterwards lead 8 is penetrated described sleeve pipe 7, utilize the described sleeve pipe 7 of back-off ring 61 socket closely of transverse conduit 6 outer surfaces then, promptly finished installation of the present utility model.
And from foregoing as can be seen, the invention of this patent is that one initiative in original sealing structure of adding is specifically designed to the transverse conduit 6 of drawing lead, in the present embodiment, this transverse conduit 6 is to offer on the external frame sidewall of described waterproof lid 5, in fact, this transverse conduit 6 also can be opened on the bottom surface of waterproof lid 5, even can be that this transverse conduit 6 is drawn from fan frame sidewall; And waterproof lid 5 can be the drum shape, also can be square, or even erose geometrical shape; Waterproof lid 5 is with back-off and the clamping mutually of card post with described fan frame 1, and can be to adopt screw connection, marine glue glue to connect or the like in application.
Certainly, above embodiment just is explanation rather than restriction the utility model, the above only is preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, and are included in the utility model patent claim.
