Detailed description of the invention
Below in conjunction with the accompanying drawings embodiments of the present invention are described further.
The embodiment one of the charger of the present invention, as shown in Figure 1 to Figure 2, including housing 1, housing 1 is internal passes through insulator
Being fixed with two shell fragment terminals 3, two shell fragment terminals 3 are connected respectively the positive and negative electrode of charger voltage output.In housing 1
Also being rotatably equipped with pin 2, pin 2 has two, and two the most corresponding two shell fragment terminals 3 of pin 2, pin 2 is inserted for correspondence
Enter in the positive and negative electrode jack of socket connector and be conducting to need by electric current by shell fragment terminal 3 in the equipment of charging.
Pin 2 includes the inserted sheet extended up and down and is located at the inserted sheet mounting seat 20 of inserted sheet lower end, two inserted sheet mounting seats
20 are wholely set or fix connection so that two pins can synchronous axial system.The both sides that the left and right of two inserted sheet mounting seats 20 is opposing
Being respectively equipped with the rotating shaft 21 that left and right extends, pin 2 is rotated by the rotating shaft 21 of inserted sheet mounting seat 20 and is assemblied in housing 1.Pin 2
Be additionally provided with the electrically conducting contact being conductively connected with inserted sheet in the downside of mounting seat 20, this electrically conducting contact can be inserted sheet directly to
The lower end, one end extending protrusion inserted sheet mounting seat 20, it is also possible to be that upper end is connected with inserted sheet, inserted sheet mounting seat is stretched out in lower end
Adaptor.
Extend and be respectively correspondingly arranged in the lower section of two pins 2 before and after two shell fragment terminals 3, turn to inserted sheet at pin 2
During perpendicular or substantially vertical with shell fragment terminal 3 state, pin, by electrically conducting contact and shell fragment terminal conductive contact, is being inserted
When foot 2 turns to the inserted sheet state parallel or substantially parallel with shell fragment terminal 3, the electrically conducting contact of pin and shell fragment terminal 3 phase
Separate, realize the conducting with shell fragment terminal and disconnection with this by the rotation of pin.Correspondingly, housing is provided with inserted sheet receiving
Groove 10.When charger does not uses, inserted sheet can be turned to holding tank 10 interior so that inserted sheet to be protected, also allow for equally filling
Electrical equipment carries, and now inserted sheet disconnects with shell fragment terminal；Inserted sheet can be produced from inserted sheet holding tank 10 when needs use, this
Time being conductively connected of inserted sheet and shell fragment terminal.
As shown in Figure 3-4, including the lamellar body 30 front and back extended, the rear end of lamellar body 30 is provided with the concrete structure of shell fragment terminal 3
The terminal 31 being connected for the both positive and negative polarity electrode exported with voltage, the middle part of lamellar body 30 is provided with for the electrically conducting contact with pin
The contact elastic arm 32 being conductively connected.Specifically, punched openings the first U-shaped gap 320 backwards on lamellar body 30, the first U-shaped seam
Forming the first cantilever design that rear end is connected with lamellar body 30, front end overhangs forward in gap 320, the first cantilever design i.e. constitutes above-mentioned
Contact elastic arm 32.Contact elastic arm 32 is owing to can overturn at inserted sheet in above-below direction generation elastic deformation for cantilever design
During to or near normal state vertical with shell fragment terminal 3, the electrically conducting contact on pin pushes up downwards press contacts elastic arm 32, contact bullet
Arm 32 has the trend upwards replied due to natural resiliency, thus ensures the reliable conducting with pin；Inserted sheet turn to
Shell fragment terminal 3 is parallel or during less parallel state, electrically conducting contact separates with contact flat spring 3, and contact elastic arm 32 is by self bullet
Property reset.
Thus, it can be known that the natural resiliency that shell fragment terminal 3 is exactly based on contact elastic arm 32 ensures to electrically connect with the stable of pin
's.So, the elastic resilience of contact elastic arm 3 just determines the degree of reliability of pin and shell fragment terminal 30.
The present invention is precisely in order to the elastic resilience of the contact elastic arm 32 improved on shell fragment terminal 3 is to improve shell fragment terminal
3 degrees of reliability being conductively connected with pin and the improvement that carries out.
Specifically, in the present embodiment, the lamellar body 30 of shell fragment terminal 3 is also stamped with opening court in the front side contacting elastic arm 32
After the second U-shaped gap 330, form in the second U-shaped gap 330 that rear end is integrally connected with lamellar body 30, front end overhangs forward the
Two cantilever designs, bend this second cantilever design and make its free end to be connected to contact the downside of elastic arm 32 backward, thus
Formed and support elastic arm 33.The elastic arm 33 that supports bent backward by the second cantilever design and formed has bigger elastic force, its
The downside of contact elastic arm 32 provide support can make to be greatly improved contact elastic arm 32 when being pressed by electrically conducting contact top upwards
Elastic acting force, too increase full wafer shell fragment terminal structure anti-fatigue performance, thus ensure that contacting elastic arm 32 conducts electricity with pin
Being reliably connected of contact site.
