Description
Technical field
The utility model relates to a kind of power supply adaptor, is specifically related to a kind of waterproof power supply adaptor structure.
Background technology
At present, LED driver or power supply adaptor usually adopt and fill with fluid sealant or utilize the mode of sealing ring to seal, to reach the effect of waterproof.Although adopt aforesaid way can reach good waterproof effect, there is production cost higher, and generative process is comparatively complicated, causes the quality of product to be difficult to management and control.Therefore, be necessary to improve prior art.
Utility model content
For overcoming the deficiencies in the prior art and Problems existing, the utility model provides a kind of waterproof construction of power supply adaptor, utilizes this waterproof construction, while reaching effective waterproof, effectively can also enhance productivity and save production cost.
The utility model is achieved through the following technical solutions: a kind of waterproof construction of power supply adaptor, comprise the housing of power supply adaptor, be positioned at the power supply lead wire at housing two ends, described housing two ends are provided with stretches into for power supply source lead-in wire the wiring hole be connected with the circuit board in housing in housing, described housing comprises upper cover and lower cover, the place of covering of upper cover and lower cover is provided with the Supersonic line for ultrasonic fusing, and described upper cover and lower cover two ends are respectively arranged with the U-lag cooperatively interacting to form described wiring hole, described power supply lead wire is provided with two or more line card for the one end be connected with described circuit board, the draw-in groove for fixing described line card is provided with in each U-lag, and the sidewall contacted with power supply lead wire in described each U-lag is provided with the latch of multiple evagination.
Further, the Supersonic line that the place of covering of described upper cover and lower cover is arranged is at least three layers.
Preferably, the latch in described each U-lag is triangular in shape; Described line card is that entirety is square structure.
The waterproof construction of the power supply adaptor that the utility model provides, by the sidewall that contacts with power supply lead wire in the U-lag of power shell being arranged the leg-of-mutton latch of multiple evagination, and the place of covering of the upper cover of housing and lower cover is provided with multilayer Supersonic line, after by ultrasonic fusing upper cover and lower cover, good sealing effectiveness can be reached, thus without the need to carrying out filling fluid sealant to power supply adaptor again or pad sealing ring carries out encapsulation process and can reach good waterproof effect, and effectively can also enhance productivity and save production cost.

Embodiment
For the ease of the understanding of those skilled in the art, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in accompanying drawing 1-5, a kind of waterproof construction of power supply adaptor, comprise the housing of power supply adaptor, be positioned at the power supply lead wire 20 at housing two ends, described housing two ends are provided with stretches into for power supply source lead-in wire the wiring hole be connected with the circuit board (each described circuit board not shown in FIG.) in housing in housing, described housing comprises upper cover 11 and lower cover 12, the place of covering of upper cover and lower cover is provided with the Supersonic line 13 for ultrasonic fusing, and described upper cover and lower cover two ends are respectively arranged with the U-lag 14 cooperatively interacting to form described wiring hole, described power supply lead wire is provided with two or more line card 21 for the one end be connected with described circuit board, the draw-in groove 15 for fixing described line card is provided with in each U-lag, and the sidewall contacted with power supply lead wire in described each U-lag is provided with the latch 16 of multiple evagination.
Due in power supply adaptor, the wiring hole at housing two ends and the sealing effectiveness covering contact position of power supply lead wire poor, thus cause the waterproof effect of power supply adaptor poor.Therefore by the sidewall that contact with power supply lead wire in described each U-lag being provided with the latch of multiple evagination, so that described upper cover is after covering with lower cover, described U-lag and power supply lead wire is made to reach the tight effect fastened.In the present embodiment, the latch in described each U-lag is triangular in shape (as shown in Figure 5), so that described U-lag and power supply lead wire reach better sealing effectiveness.In the present embodiment, the triangle latch magnitude setting in each U-lag is four layers, and described line card is that entirety is square structure, and the quantity of each power supply lead wire is set to two.
Further, in order to the waterproof effect making described power supply adaptor reach better on the whole, the Supersonic line that the place of covering of described upper cover and lower cover is arranged is at least three layers, obtains better sealing effectiveness to make described upper cover and lower cover after carrying out ultrasonic fusing; In the present embodiment, Supersonic line is preferably set to three layers.
Certainly, the waterproof construction that the present embodiment provides not only is applicable to power supply adaptor, also can be applied in LED driver, or in other power supplys.
The waterproof construction of the power supply adaptor utilizing the present embodiment to provide, directly carrying out ultrasonic fusing to the housing of power supply adaptor can reach preferably waterproof effect, do not need to carry out the measure such as filling fluid sealant or pad sealing ring to power supply adaptor again, thus effectively improve production efficiency and save production cost.
Above-described embodiment is preferably implementation of the present utility model, is not to restriction of the present utility model, and under the prerequisite not departing from inventive concept of the present utility model, any apparent replacement is all within protection range of the present utility model.
