The utility model content
For the deficiencies in the prior art, the utility model provides a kind of brand-new charger fuse structure, it has abandoned the structure that traditional employing welding manner can not conveniently be installed, remove, in case fuse damages or fusing, the consumer only needs realizing self disassembling and changes fuse.
For achieving the above object, the utility model adopts following technical scheme:
A kind of charger construction of conveniently replaced fuse, it comprises shell, printed circuit board (PCB), heating panel, the lower end of described shell is provided with mounting groove, heating panel is fixedly installed on the described mounting groove, heating panel and shell form an accommodation space, printed circuit board (PCB) is located in this accommodation space and is fixedly installed on the medial surface of heating panel, described charger construction also comprises a fuse component, described fuse component comprises the fuse body, the upper end is provided with the swing arm of nut and is welded in protective tube base on the printed circuit board (PCB), the swing arm installing hole that swing arm and shell are provided with is complementary, and the lower end of swing arm is passed the swing arm installing hole and is connected with the protective tube whorl of base, the fuse body is fixed in the lower end of swing arm, and the two ends of fuse body are electrically connected by protective tube base and printed circuit board (PCB).
Preferably, swing arm and swing arm installing hole be by being threaded of being complementary, and this kind connected mode can guarantee closely to be connected between swing arm and the shell, in fact, in the utility model, only needs a swing arm installing hole can guarantee that the lower end of swing arm is by getting final product.
Preferably, for water proof and dust proof and play effect attractive in appearance, the upper end of described swing arm is fixedly connected with a nut, and the upper end of described swing arm installing hole is provided with a depressed part, and described nut is arranged in this depressed part.
Preferably, be provided with a seal washer between described nut and the depressed part.When swing arm screwed, seal washer is crimp in depressed part, plays sealing function.
The charger construction of a kind of conveniently replaced fuse that the utility model is set forth, compared with prior art, its beneficial effect is: the fuse body is connected that no-welding type connects with printed circuit board (PCB) in the utility model, in case the fuse body damages or fusing, the consumer just can screw out shell with protective tube by swing arm easily and dismantle, self-changeable fuse body, needn't whole charger open or take away specialized maintenance even scrap, save cost, the control wasting of resources, it is convenient also to bring to use.
Description of drawings
Accompanying drawing 1 is the structural representation of the charger construction of a kind of conveniently replaced fuse of the utility model;
Accompanying drawing 3 is the structural representation of fuse component.
Embodiment
Below, by reference to the accompanying drawings and embodiment, the charger construction of a kind of conveniently replaced fuse of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
Shown in Fig. 1 ~ 3; a kind of charger construction of conveniently replaced fuse; it comprises shell 6; printed circuit board (PCB) 4; heating panel 5; the lower end of shell 6 is provided with mounting groove; heating panel 5 is fixedly installed on this mounting groove; so that heating panel 5 and shell 6 form an accommodation space; printed circuit board (PCB) 4 is located in this accommodation space and is fixedly installed on the medial surface of heating panel 5; abandoning existing fuse is fixed in and plays the over-current over-voltage protection effect on the printed circuit board (PCB) 4; in the utility model; removably connect between fuse component and the printed circuit board (PCB) 4; particularly; fuse component comprises fuse body 2; swing arm 1 and be welded in protective tube base 3 on the printed circuit board (PCB) 4 by two the PIN pins in bottom; swing arm 1 is complementary with the swing arm installing hole 61 that shell 6 is provided with; and the lower end of swing arm 1 is passed swing arm installing hole 61 and is threaded with protective tube base 3; fuse body 2 is fixed in the lower end of swing arm 1; when swing arm 1 is screwed down; fuse body 2 is placed in the space of swing arm 1 and fuse seat 3 formation; and the lower end of fuse body 2 realizes being electrically connected by the PIN pin that protective tube base 3 and its bottom are provided with at this moment; and its upper end is by swing arm 1; realize being electrically connected through protective tube base 3 and another PIN pin; realized that with this two ends of fuse body and printed circuit board (PCB) 4 are electrically connected; it is to the overcurrent-overvoltage protective effect; when needing to change; only need back out swing arm 1 and fuse body 2 be extracted namely replaceable, load and unload very convenient.
