Abstract
The utility model discloses a cable waterproof plug. The cable waterproof plug (10) comprises a first half part (112) and a second half part (114); the first half part (112) and the second half part (114) form in a matching mode a central hole (140) in interference fit with the cable (200) and an annular groove (120) matched with a mounting hole of a cabinet wall (300); and the width of the annular groove (120) is smaller than the thickness of the cabinet wall (300). Thus, the cable can be tightly attached to the hole wall of the central hole, and sealing between the cable waterproof plug and the cable is realized; and as the width of the annular groove is smaller than the wall thickness, the cable waterproof plug is deformed as squeezed by the cabinet wall, faces at two sides of the annular groove are tightly attached to the two faces of the cabinet wall, and sealing between the cable waterproof plug and the cabinet is realized.
Description
Technical field
The utility model relates to a kind of cable waterproof end plug, and it especially can introduce or draw for outdoor cabinet the waterproof construction of cable.
Background technology
Outdoor cabinet is widely used in the systems such as communication, electric power, broadcasting and TV, and its inner dress various device, is connected by cable with the external world.Because outdoor cabinet works in outdoor climatic environment, internal unit is generally all charged, and rainwater causes equipment short circuit after entering in cabinet, causes equipment performance to lose efficacy, and even sets off an explosion and fire.Therefore in the time of design outdoor cabinet, all to consider the waterproof of cable.
At present, cable waterproof mainly adopts glue sealing.Use glue sealing, human factor is larger, high to operative employee's competency profiling, and reliability is not fine, has the possibility of cracking after the glue solidifies, causes easily leaking.
Utility model content
The purpose of this utility model is, a kind of cable waterproof end plug is provided, and its waterproof is reliable.
The utility model is achieved through the following technical solutions: a kind of cable waterproof end plug, described cable waterproof end plug comprises the first half portions, the second half portions, described the first half portions and described the second half portions coordinate and are formed with the cannelure coordinating with the centre bore of cable interference fit with the installing hole in cabinet walls, and the width of described cannelure is less than the wall thickness of described cabinet walls.
As the further improvement of technique scheme, described cable waterproof end plug also comprises connection part, and described the first half portions are connected by described connection part with described the second half portions.
As the further improvement of technique scheme, the diameter on the face of cylinder that the diapire of described cannelure forms equals the diameter of the installing hole in cabinet walls.
As the further improvement of technique scheme, described cable waterproof end plug is rubber parts.
As the further improvement of technique scheme, described cable waterproof end plug is silica gel part.
The beneficial effects of the utility model are: cable waterproof end plug of the present utility model comprises the first half portions, the second half portions, described the first half portions and described the second half portions coordinate and are formed with the cannelure coordinating with the centre bore of cable interference fit with cabinet walls installing hole, the width of described cannelure is less than the wall thickness of described cabinet walls, thus, can make the hole wall of cable and centre bore fit tightly, realize the sealing between cable waterproof end plug and cable, and the width of cannelure is less than wall thickness, cable waterproof end plug is subject to described cabinet walls extruding to produce distortion, the face of cannelure both sides is close on the two sides of cabinet walls, realize the sealing between cable waterproof end plug and rack.
Brief description of the drawings
Fig. 1 is according to the schematic diagram of the deployed condition of the cable waterproof end plug of a specific embodiment of the present utility model;
Fig. 2 is the schematic diagram at the top of the merging phase of the cable waterproof end plug of Fig. 1;
Fig. 3 is the schematic diagram of the sidepiece of the merging phase of the cable waterproof end plug of Fig. 1;
Fig. 4 is the schematic diagram of the use state of the cable waterproof end plug of Fig. 1;
Number in the figure implication is as follows: 10-cable waterproof end plug; 112-the first half portions; 114-the second half portions; 140-centre bore; 120-cannelure; 300-cabinet walls; 200-cable; 132-connection part; 110-cylindrical portion; 130-plug portion.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is further detailed.
As shown in Figures 1 to 3, the cable waterproof end plug 10 of the present embodiment comprises the first half portions 112 and the second half portions 114.Described the first half portions 112 and described the second half portions 114 coordinate and are formed with the cannelure 120 coordinating with the centre bore 140 of cable 200 interference fit with the installing hole in cabinet walls 300.
As shown in Figure 2, the diameter d of centre bore 140 is less than the external diameter of cable 200.And, in described cable waterproof end plug 10, also comprise connection part 132.Described the first half portions 112 are connected by described connection part 132 with described the second half portions 114.And, in the present embodiment, between described the first half portions 112, described the second half portions 114, described connection part 132 threes, can not be split.Thus, between described the first half portions 112 and described the second half portions 114, can launch relative to each other and merge.Under the state merging in described the first half portions 112 and described the second half portions 114, cable waterproof end plug 10 is roughly the rotary body of column.
As shown in Figure 3 and Figure 4, the width L of described cannelure 120 is less than the wall thickness of described cabinet walls 300.And the diameter D1 on the face of cylinder that the diapire of described cannelure 120 forms equals the diameter of the installing hole in cabinet walls 300.The diameter D2 of the conus portion (not label) of the diameter of plug portion 130 and cannelure 120 1 sides is all greater than the diameter of the installing hole in cabinet walls 300.
Described cable waterproof end plug 10 can be flexible rubber parts or flexible silica gel part.The cable waterproof end plug of the present embodiment is a kind of waterproof end plug taking silicon rubber as design of material.Rely on the design feature of cable waterproof end plug and the elasticity of silicon rubber to realize the function of waterproof.
In the time of assembling cable, first cable 200 is put into the centre bore 140 of cable waterproof end plug 10, then, cable waterproof end plug 10 ecto-entads are packed in cabinet walls 300 along direction of insertion X, cabinet walls 300 is snapped in the cannelure 120 of cable waterproof end plug completely.
Because the width L of cannelure 120 is less than the wall thickness of described cabinet walls 300, cable waterproof end plug is squeezed and produces distortion, and the face of cannelure both sides is close on the two sides of cabinet walls, realizes the sealing between cable waterproof end plug and rack.And the diameter d of centre bore 140 is less than the external diameter of cable 200, can make the hole wall of cable and centre bore fit tightly, realize the sealing between cable waterproof end plug and cable.
The cable waterproof end plug of the present embodiment provides a kind of easy cable waterproof end plug, has avoided the impact of human factor, workable, has increased the reliability of waterproof, and volume is little, and cost is low.Meanwhile, this waterproof end plug volume is little, installs simply, is applicable in the rack of compact conformation.
Above embodiment has been described in detail the utility model, but these not form restriction of the present utility model.Protection range of the present utility model is not limited with above-mentioned execution mode, as long as the equivalence that those of ordinary skill in the art do according to the utility model institute disclosure is modified or changed, all should include in the protection range of recording in claims.
