Description

Wiring hole waterproof construction and waterproof box

Technical Field

The utility model relates to the technical field of electrical devices, in particular to a waterproof structure of a wiring hole.

Background

The electric equipment installed outdoors is internally provided with various circuit boards and instruments, and after the electronic elements are wetted by water, the conditions of short circuit, poor contact and the like can be inevitably generated. In the outdoor environment of wind and rain, in order to avoid the water vapor from entering the equipment and further affecting the electrical performance of the equipment, the opening and the connecting seam of the cabinet body or the box for installing the equipment are generally subjected to waterproof treatment. Electronic components between different electrical apparatuses often need to be connected to each other by electric wires, which requires the electric wires to be extended to the outside through wiring holes of the box or the cabinet. Generally, the waterproof treatment at the wiring hole only comprises the steps of penetrating the electric wire through a rubber plug with a through hole and then plugging the rubber plug into the wiring hole, so that the sealing and waterproof effects are achieved.

Because the rubber buffer is the direct card in the wiring hole, and is little with the area of contact on wiring hole edge, when the rubber buffer misplaces, the gap can be exposed at rubber buffer and wiring hole edge, and steam will directly get into in the electrical equipment to influence electronic component's performance.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a waterproof structure of a wiring hole and a waterproof box, which have the characteristics of good waterproof effect and convenience in installation.

In order to realize the purpose, the following technical scheme is provided:

Detailed Description

The waterproof structure of the wiring hole and the waterproof case of the utility model will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, fig. 2, fig. 6, a wiring hole waterproof construction, including wiring hole and rubber buffer 2, be equipped with first sealing washer 3 and second sealing washer 4 on rubber buffer 2's the outer wall and the inner wall respectively, be equipped with first sleeve 5 and second sleeve 6 along the outside edge circumference in wiring hole, rubber buffer 2's the outside is equipped with buckler 7, and buckler 7 suit is between first sleeve 5 and second sleeve 6, and rubber buffer 2 suit is in second sleeve 6.

A first sleeve 5 and a second sleeve 6 are arranged on the outer side of the shell wiring hole from outside to inside, and a containing cavity is formed between the first sleeve 5 and the second sleeve 6. The first sleeve 5 and the second sleeve 6 are integrally formed with a cabinet or a box body 12 for mounting electrical equipment, so that the structural strength is ensured. When using, pass the hole in rubber buffer 2 middle part earlier and stretch into the cabinet body or the box of installing electrical equipment with the electric wire, then with rubber buffer 2 suit in second sleeve 6, the intracavity is held in the suit of buckler 7 between first sleeve 5 and second sleeve 6. Because there is second sealing washer 4 rubber buffer 2 is inside, forms in close contact with between electric wire and the second sealing washer 4, can prevent in steam gets into equipment from rubber buffer 2's hole. Because the buckler 7 closely contacts with the inner wall of first sleeve 5 and the outer wall of second sleeve 6, inside the unable chamber of holding of following between first sleeve 5 and the second sleeve 6 of steam gets into the wiring hole. In addition, rubber buffer 2 constitutes double waterproof construction through the inner wall in close contact with of first sealing washer 3 with second sleeve 6, even vapor can break through buckler 7, gets into the chamber that holds between first sleeve 5 and the second sleeve 6, and first sealing washer 3 also can play waterproof effect to the water-proof effects in wiring hole has been improved greatly.

Further, as shown in fig. 1, fig. 2, fig. 3, fig. 4, fig. 6, fig. 7, and fig. 8, the front section of the waterproof cover 7 is cylindrical so as to be sleeved in the accommodating cavity between the first sleeve 5 and the second sleeve 6; the rear section is frustum shape, and rubber buffer 2 is fixed in the middle part of the rear section of buckler 7. In this embodiment, the waterproof cover 7 and the rubber plug 2 are both made of rubber and are integrally formed.

Further, as shown in fig. 2 and 6, in order to avoid the situation that the wire shakes during use and the waterproof cover 7 is accidentally loosened, the waterproof cover 7 is fixed on the first sleeve 5 through a fastening structure.

Further, as shown in fig. 2 and 5, the fastening structure is a mounting sleeve 8, and the inner wall of the rear section of the mounting sleeve 8 is matched with the shape of the rear section of the waterproof cover 7, so that the mounting sleeve 8 can be tightly attached to the frustum-shaped rear section of the waterproof cover 7; 8 anterior segments of installation sleeve are equipped with the internal thread, and the outer wall of first sleeve 5 is equipped with the external screw thread, passes through threaded connection between installation sleeve 8 and the first sleeve 5.

When using, need pass installation sleeve 8 and rubber buffer 2 with the electric wire earlier, in second sleeve 6 of rubber buffer 2 suit, when the cavity is held in the suit between first sleeve 5 and second sleeve 6 to buckler 7 suits, screws firmly installation sleeve 8 on first sleeve 5 again. Because the length of the cylindric anterior segment of buckler 7 is less than the length of first sleeve 5 and external screw thread for the inner wall of installation sleeve 8 can closely laminate with the frustum form back end of buckler 7, reaches fastening and inclosed effect.

Further, as shown in fig. 6, 7 and 8, the fastening structure includes a latch 9 fixed on the outer side of the first sleeve 5 and a bayonet 10 fixed on the waterproof cover 7, and the waterproof cover 7 is connected with the first sleeve 5 through the bayonet 10 and the latch 9. When the rubber buffer 2 suit was in second sleeve 6, when the cavity was held in the suit between first sleeve 5 and second sleeve 6 to waterproof cover 7 suit, again with waterproof cover 7 detain in the outside of first sleeve 5 can. The bayonet 10 is located the rear side of the waterproof cover 7 to ensure that the rubber plug 2 can extend into the second sleeve 6 when being clamped with the buckle 9.

Further, as shown in fig. 1, 2, 3, 4, 7, and 8, a third sealing ring 11 is provided on the outer side of the waterproof cover 7, and the waterproof cover 7 is kept sealed between the first sleeve 5 and the second sleeve 6 by the third sealing ring 11, thereby further improving the waterproof effect.

A waterproof box comprises a box cover 1 and a box body 12, wherein the box cover 1 and the box body 12 can be buckled together. The box body 12 is provided with the wiring hole waterproof structure.

Waterproof box and as before wiring hole waterproof construction assorted design, the outside in waterproof box wiring hole sets up first sleeve 5 and second sleeve 6 from the extroversion inwards, and waterproof box and first sleeve 5 and second sleeve 6 are integrated into one piece. When using, pass the hole in rubber buffer 2 middle part earlier and stretch into and install in electrical equipment box body 12, then with rubber buffer 2 suit in second sleeve 6, the intracavity is held to the water proof cover 7 suit between first sleeve 5 and second sleeve 6 can. The waterproof box greatly improves the waterproof effect of the wiring hole through multiple waterproof design, and avoids the adverse effect caused by the fact that water vapor enters the box body 12 and the equipment is affected with damp. In addition, the structural design of waterproof box is simple, and the installation of rubber buffer 2 is used also comparatively conveniently.
