The beneficial effects of the utility model have:
This connector is provided with contact cylinder mould in socket, using the contact pin on contact cylinder mould cooperation plug, guarantees socket
With plug stable connection, adapt to the connection of high current, avoid high current by when therefore poor contact generate a large amount of heat.
First connector and contact head include cooling fin and the contact chip equipped with several pins, and contact chip can effectively be dissipated
Heat, while being attached using pin thereon, the design of contact chip can radiate and be electrically connected, cooling fin
Setting can prevent two neighboring contact chip from generating eddy current effect because of gap-contact.
Detailed description of the invention
With reference to the accompanying drawing and specific embodiment the utility model is described in further detail, in which:
