The electronic equipment with the interface is usually required to be provided with a waterproof structure at the interface in order to prevent rainwater from entering the interface or influencing the normal use of the equipment inside the equipment. The existing waterproof structure is generally that a sealing ring is arranged at a connector or a waterproof plate is arranged outside the connector to shield rainwater, but the sealing ring is influenced by the rainwater for a long time and is easy to damage and leak water, and the problem that the rainwater enters the connector or the inside of equipment from the position which is not shielded by the waterproof plate can also exist. Therefore, these waterproof structures have poor waterproof effects.

In order to solve the above problem, as shown in fig. 1 to 6, the utility model discloses at first provide an interface waterproof construction, this interface waterproof construction's water-proof effects is better, and the rainwater is difficult to get into inside interface or the equipment.

As shown in fig. 2 to 3, specifically, the interface waterproof structure includes a housing 1 and a sealing assembly 2, a wiring groove 11 and a waterproof groove 12 communicated with the wiring groove 11 through a wiring hole 13 are arranged in the housing 1, an interface 111 for connecting a cable 6 is arranged in the wiring groove 11, the waterproof groove 12 has a first opening 121 communicated with the outside, and both the first opening 121 and the wiring hole 13 are used for penetrating the cable 6; the sealing member 2 is provided in the waterproof groove 12 and the wiring hole 13, and seals the wiring hole 13.

As before, the current waterproof structure that sets up the sealing washer at the interface or set up the waterproof board in the interface outside and shelter from the rainwater is relatively poor in water-proof effects, still gets into interface or equipment inside easily with water, influences the normal use of equipment. In the interface waterproof structure provided by the novel embodiment, the interface is arranged in the wiring groove 11, and during wiring, the cable 6 needs to be firstly inserted into the waterproof groove 12 through the first opening 121, and then extends into the wiring groove 11 through the wiring hole 13 and is connected with the interface 111, so that the interface 111 supplies power or communicates with the outside; the sealing assembly 2 can seal the wiring hole 13, so that even if rainwater enters the waterproof groove 12 through the first opening 121, the rainwater cannot enter the wiring groove 11 through the wiring hole 13, flushing at various angles can be prevented, the waterproof sealing performance of the waterproof structure of the interface is ensured, and the interface 111 and equipment can be used normally; meanwhile, the side wall of the waterproof groove 12 can shield the wiring hole 13 and the sealing component 2, so that the function of keeping off rain is achieved, external rainwater cannot directly hit the sealing component 2 easily, the sealing component 2 is prevented from contacting water for a long time and being damaged to leak, and the sealing effect of the sealing component 2 is guaranteed.

The housing 1 may be made of plastic, such as PC + ABS. The first opening 121 is preferably opened in a side wall of the waterproof groove 12 away from the wire connection hole 13. In use, the first opening 121 is usually disposed downward, so that rainwater falling down is not easily introduced into the waterproof groove 12 from the first opening 121.

In one embodiment, the sealing assembly 2 includes a sealing compound filled in the watertight channel 12. After the cable 6 is connected, the sealant is filled into the waterproof groove 12 through the first opening 121, and the sealant is cured through heating curing or normal temperature curing after the filling is completed, so that the sealing and the waterproofing of the wiring hole 13 are realized. The sealant can be epoxy resin glue, polyurethane glue, silica gel and the like, and the curing time can be adjusted according to the type and the dosage of the specific sealant, and is usually 10-30 minutes. The sealant is a liquid material when not cured, can be filled in the uneven positions of the inner wall of the waterproof groove 12 after being injected into the waterproof groove 12, can be freely formed, is not limited by the shape of the waterproof groove 12, has a simple and convenient processing mode, can form continuous colloid after being cured, plays a reliable sealing role, and is not easy to leak. Meanwhile, the sealant has the characteristics of corrosion resistance, damage resistance and fatigue resistance, and is long in service life.

In another embodiment, as shown in fig. 3, the sealing assembly 2 includes a first sealing member 21 disposed in the wire connection hole 13, the first sealing member 21 having a through hole 211 for passing the cable 6 therethrough. Since the first sealing member 21 has a certain deformation capability, the inner diameter of the wire connecting hole 13 needs to be larger than the outer diameter of the cable 6 and smaller than the outer diameter of the first sealing member 21, and the inner diameter of the through hole 211 needs to be equal to or slightly smaller than the outer diameter of the cable 6, so as to ensure the sealing effect of the first sealing member 21. The first sealing member 21 can directly seal the wiring hole 13, and the waterproof effect at the wiring hole 13 is improved.

The outer peripheral wall of the first sealing member 21 has a catching groove 212, and the edge of the wire connection hole 13 is caught in the catching groove 212. The edge cooperation of draw-in groove 212 and wiring hole 13 can fix first sealing member 21, avoids first sealing member 21 to deviate from wiring hole 13 and influence sealed effect. Meanwhile, the diameter of the two ends of the first sealing element 21 in the axial direction can be larger than the inner diameter of the wiring hole 13, so that rainwater can be prevented from entering the wiring groove 11 from a gap between the inner wall of the wiring hole 13 and the first sealing element 21, and the sealing effect is further improved. The locking groove 212 of the first sealing element 21 may be configured as a ring groove, and the inner edge of the wire connecting hole 13 is locked into the ring groove. Alternatively, a plurality of clamping grooves 212 arranged at intervals may be formed along the outer circumferential wall of the first sealing member 21, a plurality of clamping blocks arranged corresponding to the clamping grooves 212 may be protrudingly formed on the inner side wall of the wire connecting hole 13, and when the first sealing member 21 is mounted in the wire connecting hole 13, the clamping blocks are clamped in the clamping grooves 212 to fix the first sealing member 21.

In the illustrated embodiment, the waterproof interface structure is provided with both the sealant and the first sealing member 21, so that double waterproofing is achieved, the waterproof capability of the waterproof interface structure is improved, and a high waterproof level of IP66 is achieved. Of course, in other embodiments, only one of the sealant and the first sealing member 21 may be provided as long as the sealing and waterproofing of the wiring hole 13 can be achieved, and there is no particular limitation here.
