Detailed description of the invention

As follows the application scheme is further described:

Referring to accompanying drawing 1 to accompanying drawing 5, a kind of water proof and dust proof charge power supply, including power shell 1, power supply mainboard 2 and binding post 3, this power shell 1 is shape, its both ends open is closed by end cap 4 respectively, the end cap 4 of any one end of power shell 1 offers porose position wear for this binding post 3, this binding post 3 is electrically connected with power supply mainboard 2, this power shell 1 includes the upper shell 11 and the lower house 12 that cooperate, this upper shell 11 jointly encloses with lower house 12 and forms the inner chamber 10 disposing this power supply mainboard 2, this inner chamber 10 lateral symmetry is arranged with power supply source mainboard 2 in parallel and blocks the draw-in groove 101 put, these inner chamber 10 both sides are respectively provided with inclined plane 102, it is formed with cavity 104 between this inclined plane 102 and sidewall 103 of power shell 1, this inclined plane 102 offers some through holes 105 running through and connecting this cavity 104 and power shell inner chamber 10, this power supply mainboard 2 is provided with some keeper 21(and is made up of fixture 21a and movable part 21b), those keepers 21 coordinate fixing by screw with the through hole 105 in inclined plane 102.

Tradition should be arranged the through hole on power shell sidewall by such scheme change into and be arranged in an inclined plane of inner chamber, screw is directed through to cavity, power shell table side is made to have the integrity degree of the best, stop dust and steam and enter to the possibility within power shell by through hole, not only improve the protection of product I P(foreign body intrusion) raising of grade, there is again preferably aesthetics.

The bottom extension of this upper shell 11 is provided with the first card along 111, the upper opening place of this lower house 12 be provided with coordinate this first card along 111 second card along 121, and take, for the bottom margin 112 of this upper shell 11, the convex edge 122 put, this second card has bending 121a down along 121.

The bottom surface of this upper shell 11 and the first card form occlusal crib 110 between 111, push from the end face of lower house 12, the second card coordinating this lower house 12 realizes fixing along 121 and convex edge 122, utilize bending 121a structure to realize spacing more closely, it is to avoid the cooperation between upper and lower casing is loose simultaneously.

This U-shaped shape of lower house 12, the cavity 104 that between its vertical side walls 103 and inclined plane 102 of this inner chamber 10, Formation cross-section is triangular in shape, inclined plane 102 is just convenient for people to perform the tightening or unloading operation of screw at U-shaped opening part upward, make product assembling disassemble more simple, fast.

Being provided with position, flower-shape hole 13 on the end face that this power shell 1 is relative with end cap 4, this position, flower-shape hole 13 has some leaflets 131 with the distribution of center, hole divergent shape, and the cross section of this leaflet 131 is in elongate shape. This leaflet 131 can be followed when screw screws in and be deformed upon, thus by screw clamping; And the leaf 131 of debating of elongate has bigger deformation compatibility space, it is possible to realize coordinating to the screw within the scope of certain diameter, significantly reduce the chance occurring not mating situation; Meanwhile, leaflet 131 can with housing in the lump molding, it is not necessary to carries out drilling operating more individually, decreases trouble, will not increase production cost and improve the efficiency of production.

The table side of this power shell 1 is provided with some radiating fins or heat radiation fin 14, forms radiating groove 141 between two between radiating fin or heat radiation fin 14, and whole power shell 1 is exactly a radiator, meets the radiating requirements of power supply mainboard 2.

This end cap 4 is plastic end cover, and it is provided with and the flange 41 of power shell 1 matching ends, and the medial surface that this end cap 4 is relative with power shell 1 is provided with ring-shaped groove 42, is provided with sealing strip or sealing ring 5 in this ring-shaped groove 42. Traditional irony end is more become plastic end cover, not only injection mo(u)lding is convenient, and be connected cooperation between the flange of plastic end cover and power shell and also can accomplish more tight, the sealing strip simultaneously arranged or sealing ring, be conducive to IP(foreign body intrusion to protect) lifting of grade.

Described end cap 4 offers position, some holes 43, pass by this some holes position for operation button Huo and display lamp, inside end cap 4, this some holes position 43 corresponding is provided with sealed film 6, utilize sealed film 6 that this some holes position 43 is done effective closure after installing button and display lamp, the extraneous dust of isolation and steam, be conducive to IP(foreign body intrusion to protect) lifting of grade.

The position of this draw-in groove 101, higher than the bottom surface of this inner chamber 10, makes and there is space 100 between this power supply mainboard 2 and inner chamber bottom surface, the size in this space 100 according to this charge power supply EMC EMI require and design.

Above-mentioned preferred implementation should be regarded as the illustration of the application scheme embodiment, all identical with the application scheme, approximate or make based on this technology deduction, replacement, improvement etc., be regarded as the protection domain of this patent.
