Specific embodiment

The utility model is further described in more detail below with reference to embodiment.

Power supply adaptor 100 provided by the embodiment of the utility model, as described in Figure 1, comprising: shell 110, by input power Input voltage be converted to the conversion circuit plate 120 of output voltage, more than two pins 130 connecting with the input power； Wherein, shell 110 can have multi-section to be grouped as, and a part is only shown in Fig. 1；Conversion circuit plate 120 may include electric bridge, become The circuits such as depressor and voltage regulator circuit, commonly used in the input powers such as alternating current are converted to 12V, 24V that electric tool etc. uses Equal DC voltages；For the pin 130 for being inserted into AC outlet, Xiang Suoshu conversion circuit plate 120 provides alternating current, described to insert The number of foot 130 can be two or three etc., can such as be existed according to the AC outlet standard setting of different countries and regions China can be set to two, may be set to be three；

The pin 130 can be fixedly connected on the shell 110 by modes such as hot melts, and the of the pin 130 The shell 110 is stretched out in one end 131, connect with external communication electrical socket, and the second end 132 of the pin 130 stretches to shell 110 Inside is connect with conversion circuit plate 120；Setting can have elasticity corresponding with each pin 130 on the conversion circuit plate 120 Clamping terminal 121, each resilient clamp terminal 121 distinguish the second end 132 of the corresponding pin 130 of resilient clamp, are formed Electrical connection.The resilient clamp terminal 121, which can be, to be made of metal, by the modes such as welding and conversion circuit plate 120 Other circuit connections；When the conversion circuit plate 120 is assembled into the shell 110,121 resilient clamp of resilient clamp terminal The second end 132 of the pin 130 forms electrical connection.The resilient clamp terminal 121 can be set in the conversion circuit plate 120 sides towards the pin 130；

The resilient clamp terminal 121 may include a metab and two elastic clip gripping arms, and metab is used for It is welded with the route on the conversion circuit plate 120；Two elastic clip gripping arms can be set in the metab two sides, metal Pedestal and two elastic clip gripping arm sections can be triangular in shape, and two elastic clip gripping arms are mutually supported；The conversion circuit plate 120 When being assembled into the shell 110, the second end 132 of the pin 130 struts described two elastic clip gripping arms, described two elasticity The second end 132 of pin 130 described in gripping arm；

In this way, no longer need to connect pin 130 and conversion circuit plate 120 by modes such as welding with conducting wire when assembling, from And production stage is saved, and then saved cost；Connection pin 130 and conversion circuit plate can be easily separated in maintenance 120。

As a kind of implementation, Fig. 2 is the 3-D view of an angle of Fig. 1, and Fig. 3 is the three of conversion circuit plate 120 Dimensional view；As shown in Figures 2 and 3, usual conversion circuit plate 120 is close to shell towards the one side of pin 130, no longer placement electronics Element, electronic component are all disposed within backwards to the bottom surface of pin 130, therefore, the resilient clamp terminal 121 can be arranged in institute State bottom surface of the conversion circuit plate 120 backwards to the pin 130；It can be arranged in the conversion circuit plate 120 and correspond to each insert The through hole 122 of foot 130, the resilient clamp terminal 121 are set to bottom surface of the conversion circuit plate 120 backwards to the pin 130, The second end 132 of each pin 130 penetrates through hole 122 and connect with corresponding resilient clamp terminal 121.

It, can be on the metab of resilient clamp terminal 121 by taking section is the resilient clamp terminal 121 of triangle as an example Same that through hole is arranged, the through hole on metab is connected to the through hole 122 of conversion circuit plate 120；The second of pin 130 End 132 penetrates the through hole 122 of through hole and conversion circuit plate 120 on metab, struts two elastic clip gripping arms, is formed Connection.

Resilient clamp terminal 121 is set backwards to the bottom surface of the pin 130 in conversion circuit plate 120, may be implemented to convert 120 single side layout elements of circuit board reduce 120 complexity of conversion circuit plate.

The above, the only most preferred embodiment of the utility model, are not intended to limit the protection of the utility model Range, any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention etc., should be included in Within the protection scope of the utility model.
