Embodiment
Below in conjunction with drawings and Examples, the utility model is further described.
The first embodiment
This waterproof power supply adaptor, comprise the shell 1 that coordinates up and down assembling, be positioned over the electronic circuit board 4 between the upper cover 1.1 of shell and the cavity of lower cover 1.2, the power supply lead wire terminal 2 of connecting electronic wiring board 4, its upper cover 1.1 both sides corresponding power lead terminals 2 extend U-shaped wiring hole 2.2, be provided with D shape or sealing U-shaped rubber ring 3 and U-shaped wiring hole and be sealed and matched on power supply lead wire terminal 2
Referring to Fig. 7, adopt monolateral U-shaped wiring hole, only have upper cover 1.1 that U-shaped wiring hole 2.2 is set, during assembling, first sealing U-shaped rubber ring 3 is packed into the groove position of power supply lead wire terminal 2 correspondences, again power supply lead wire terminal 2 and upper cover U-shaped wiring hole 2.2 are connected, in electronic circuit board 4 connecting lead wires and placement cavity.Then close and close lower cover, lower cover is placed in to the Position Approximate of assembling, pressure a little, upper and lower covers just can be easy to coordinate assembling, and this is to be respectively arranged with angle 1.3 and limited post 1.9 due to lower cover cooperation place and inwall, closes and while closing, has positioning action; And the cooperation of proof wire clip 2.1 full-embedded types is connected to U-shaped wiring hole 2.2, not only stable but also accurate positioning.During assembling, under the effect of angle and limited post, upper and lower covers can be assembled smoothly.Finally, the connection of upper and lower covers utilizes supersonic machining process welding, and its welding track is upper and lower covers periphery, acts on flange, and bonding area is large; The shell wall thickness of non-welding reduces, and saves material.
Referring to Fig. 2, visible sealing principle of the present utility model: be sealed and matched and carry out seal protection with U-shaped wiring hole slot by sealing U-shaped rubber ring 3 and proof wire clip 2.1 between U-shaped wiring hole 2.2 and power supply lead wire terminal 2; Top planes and the groove 1.5 of sealing U-shaped rubber ring 3 are sealed and matched, proof wire clip 2.1 and the 1.7 fitted seal clampings of water-proof wire draw-in groove; Upper and lower covers cooperation place crush seal circle 5 forms and is tightly connected, and realizes sealing effect.Like this, the form of the interior external seal of the cooperation place of upper and lower covers enforcement reaches the effect of secondary seal.On outer surface, flange is used ultrasonic bonding, makes to weld contact-making surface and increases, and sealing effect is better, and sealing is stronger.Through multi-sealed protection, stronger assurance water proofing property, practicality.
Contrast prior art, technical characterictic of the present utility model specifically has following improvement: after described upper and lower covers assembling, the water inlet that upper and lower covers and proof wire clip 2.1 form is " T " font.The upper and lower covers of prior art respectively correspondence arranges wiring hole, is generally square or circular, and the water inlet that after assembling, upper and lower covers and proof wire clip form is " ten " font; And upper and lower covers is inhomogeneous to rubber ring pressure, cause rubber ring because unbalance stress is out of shape, produce larger space.Contrast prior art, the utility model has lacked a water inlet, and 3 active forces that are subject to upper cover 1.1 of sealing U-shaped rubber ring, therefore stressed evenly not yielding, guarantees to seal U-shaped rubber ring 3 and normally works.Visible, this improvement water proofing property is better, and the life-span of rubber ring is longer.
The second embodiment
Referring to Fig. 5, this waterproof power supply adaptor, it is different from the first embodiment part and is: power supply lead wire terminal 2 arranges two or more proof wire clips 2.1, so upper and lower covers is provided with U-lag and the water-proof wire draw-in groove 1.7 of respective amount simultaneously.The present embodiment is mainly applicable to lead-in wire often or thicker situation, and the increase of proof wire clip quantity makes the assembling of terminal and upper and lower covers more firm.
Other does not state part with the first embodiment.
The utility model is widely used: in daily life, for the waterproof construction that need to go between housing from internal electronic element, all can adopt the design that in this case, U-shaped wiring hole coordinates with power supply lead wire terminal.
Above-mentioned is preferred version of the present utility model, and those of ordinary skills are to its simple modification or transformation, within all dropping on protection range of the present utility model.
