Description

The waterproof construction of shell wire casing

Technical field

It the utility model is related to a kind of waterproof construction of shell wire casing, wire casing on more particularly to a kind of power adapter shell Waterproof construction.

Background technology

At present, known wire casing structure is mostly smooth plane or curved surface, when line card assembles with wire casing, mutual amount of interference It is more difficult to more greatly assemble, but the water resistance of the waterproof power supply assembled is better, it is seen that convenient for assembly with water resistance is mutually right Vertical, equalization point between the two is the difficult point of the art.Chinese patent literature CN202475996U was in 2012 10 The moon discloses a kind of waterproof construction of power supply adaptor on the 3rd, specifically discloses the power supply including housing and positioned at housing both ends and draws Line, housing corresponding power lead are provided with wiring hole, and power supply lead wire is provided with seal member, power supply lead wire with wiring hole connecting place One end through wiring hole and being tightly connected therewith；The other end of power supply lead wire is exposed on housing；It is provided with the groove position The convex glue of line card, the convex glue of line card are integrated setting with proof wire clip；The left and right sides of the convex glue of line card is provided with the assembling that can accommodate housing Space.The waterproof construction between housing and line card in the structure is realized by convex glue and assembling space, but waterproof effect is poor, Therefore, it is necessary to it is further improved.

Utility model content

It is low that the purpose of this utility model aims to provide a kind of simple and reasonable, easy to assembly, good sealing effect, cost The waterproof construction of shell wire casing, to overcome weak point of the prior art.

By a kind of waterproof construction of shell wire casing of this purpose design, including shell, shell, which is provided with, is used for clamping line card Wire casing, it is characterised in that：The wire casing inwall is inwardly protruding more than a circle annular waterproof convex tendon, and waterproof convex tendon closely squeezes Wire fastener.

The waterproof convex tendon matter is hard, and there are tip or arc tips in section, and tip or arc tips are squeezed on the soft line card of matter.

Outwards depression has annular neck to the wire casing inwall, and line card is provided with tongue, and tongue is correspondingly embedded in neck.

The shell includes the upper lid and lower cover mutually assembled, and the wire casing is mutually assembled by upper lid and lower cover.

The upper lid is provided with U-lag, has the opening of planar section closing U-lag on lower lid, forms wire casing.

The inwardly protruding waterproof convex tendon for having U-shaped of the U-lag inwall, lower cover plane corresponding with U-lag are provided with linear Waterproof convex tendon, the waterproof convex tendon of U-shaped and linear waterproof convex tendon collectively form the waterproof convex tendon of annular.

The waterproof convex tendon of the U-shaped coordinates with linear waterproof convex tendon dislocation.

The utility model makes waterproof convex tendon realize interference fit with line card, and lead to by setting waterproof convex tendon in wire casing Assembly method up and down is crossed, makes the hard waterproof convex tendon of matter that elasticity extruding occur with the soft line card of matter, makes line card even closer with wire casing Coordinate, so as to improve water resistance；This structure is improved on original structure, and manufacturing cost is low, easy to assembly.

Embodiment

Below in conjunction with the accompanying drawings and embodiment is further described to the utility model.

Referring to Fig. 1-Fig. 6, the waterproof construction of this shell wire casing is used for power supply adaptor, and it includes shell 1,1 liang of shell Side is respectively provided with the wire casing 2 of clamping line card 5, the inwardly protruding waterproof convex tendon 2.1 for having two ring shapes of the inwall of wire casing 2, waterproof The squeezed tight line card 5 of convex tendon 2.1.Waterproof convex tendon 2.1 realizes interference fit with line card 5, is specifically, the hard waterproof convex tendon 2.1 of matter Elastic extruding occurs for soft line card 5 with matter, line card 5 and 2 even closer cooperation of wire casing is made, so as to improve water resistance.

Furtherly, waterproof convex tendon 2.1 is by the integrated injection molding of shell 1, therefore matter is hard, and its section is in class triangle, institute To there is tip, the tip is squeezed on the soft line card 5 of matter, to reach waterproof purpose.

Furtherly, outwards depression has annular neck 2.2 to the inwall of wire casing 2, and the end of line card 5 is provided with tongue 5.1, tongue 5.1 are correspondingly embedded in neck 2.2, and firm clamping line card 5, structure is reliable.

Furtherly, shell 1 includes the upper lid 3 and lower cover 4 mutually assembled up and down, and wire casing 2 is mutual by upper lid 3 and lower cover 4 It is assembled.

Furtherly, upper lid 3 is provided with U-lag, has the opening of planar section closing U-lag on lower cover 4, forms wire casing 2, It is easy to assembly simple in the U-lag embedded first of line card 5 during assembling.

Furtherly, the inwardly protruding waterproof convex tendon 2.1 for having U-shaped of U-lag inwall, in the plane corresponding with U-lag of lower cover 4 Provided with linear waterproof convex tendon 2.1, the waterproof that the waterproof convex tendon 2.1 of U-shaped collectively forms annular with linear waterproof convex tendon 2.1 is convex Muscle 2.1, during assembling, line card 5 extrudes with the phase of waterproof convex tendon 2.1 of U-shaped first, is then squeezed again with the linear phase of waterproof convex tendon 2.1 Pressure, makes the surface of line card 5 obtain annular extrusion, it is ensured that waterproof effect.

Furtherly, the waterproof convex tendon 2.1 of U-shaped coordinates with the linear dislocation of waterproof convex tendon 2.1, makes lid 3 and lower cover 4 Can close fit.

Furtherly, the waterproof convex tendon 2.1 of two ring shapes is set and the both sides of neck 2.2, raising waterproof effect respectively.

Above-mentioned is preferred scheme of the present utility model, and general principle of the present utility model, principal character has been shown and described And the advantages of the utility model.Those skilled in the art should be recognized that the utility model is not restricted to the described embodiments, on State and simply illustrate principle of the present utility model described in embodiment and specification, do not departing from the spirit and scope of the utility model On the premise of the utility model also have various changes and modifications, it is new that these changes and improvements both fall within this claimed practicality In the range of type.The utility model requires protection scope is defined by appended claims and its equivalent.
