Specifically, the elastic clamping component includes the first clamp arm 3 and the second clamp arm 4 of fixed pcb board, described
First clamp arm 3 includes the fixing end being arranged on fixed frame 2 and the elastic clamping extended to form is tilted down by fixing end
End, in the present embodiment, the elastic clamping end is formed by opening up a notch on the first clamp arm 3, when pcb board card
When entering between the first clamp arm 3 and the second clamp arm 4, pcb board jacks up the elastic clamping end of the first clamp arm 3, and first clamps
Elastic deformation will occur according to the size of pcb board for the elastic clamping end of arm 3, and coordinate with the second clamp arm 4 and clamp pcb board admittedly
It is scheduled on fixed frame 2, wherein, 3 elastically-deformable range of the first clamp arm is the dimensional tolerance of pcb board that can be compatible with, and is led to
It crosses using the above structure, card is put or to dismantle pcb board convenient, fast.
Further, several first blocks 31 are also provided on first clamp arm 3, first block 31 can
Blocking pcb board run-off the straight is fallen, and in the present embodiment, the end at 3 elastic clamping end of the first clamp arm is integrally formed with first
Block 31, when preventing the card from putting the pcb board of minimum dimension, due to the insufficient clamping force between the first clamp arm 3 and the second clamp arm 4
It falls.
In the present embodiment, second clamp arm 4 is equipped with several second blocks 41, effect and 31 phase of the first block
Together, this will not be repeated here.
In addition, the quantity of clamp arm can be multiple, and being not limited in the present embodiment two in elastic clamping component, make
For another embodiment of the utility model, elastic clamping component includes the first fixing piece and can be slided with respect to the first fixing piece
The second dynamic fixing piece, the first fixing piece can be connected with spring between the second fixing piece, be stretched by the reset of spring by pcb board
It is clamped between the first fixing piece and the second fixing piece, certainly, elastic clamping component can also be by having deposited in the prior art
The mode of realization elastic clamping realize, and be not limited to the above embodiment.
The bindiny mechanism include being molded over rotary connector 5 on fixed frame 2 or connector 6 and with the rotation
What connector 5 or connector 6 matched, the connector 6 or rotary connector 5 being molded on backboard 1, the rotary connector 5
