Pin connector

Affiliated technical field

The utility model relates to a kind of pin connector, relate in particular to a kind of reach with dock socket connector really, the pin connector that reliably electrically conducts.

Background technology

Be to simplify the power connector structure and improve the fail safe that power connector is pegged graft at present, some connector manufacturers are designed to the electrical and magnetic connection of the supply socket connector corresponding with existing attaching plug connector.

Usually, the existing power supply pin connector comprises plurality of conductive terminals, when described pin connector and described socket connector are pegged graft mutually, be bonded together by the two mutual magnetic attraction, the conducting terminal of pin connector replaced simultaneously and by the socket connector terminal and realized mutual electrically conducting.

Yet, because the needs of transmission power supply signal, the conducting terminal of general existing pin connector all has bigger contact surface behind bending forming long-pending, and meaning is along the plane perpendicular to the grafting direction these conducting terminals to be sectioned, and institute's source terminal cross-sectional width of disconnecting is bigger.When this attaching plug connector and supply socket connector are pegged graft,, so make that easily being in two connectors that magnetic connects separates, and can't reach really, electrically conduct reliably because the bigger elastic force that power supply terminal provided of cross section is also bigger.

The utility model content

The purpose of this utility model is to provide a kind of pin connector at the defective that above-mentioned prior art exists, and can realize and dock between socket connector really, electrically conduct reliably.

For achieving the above object, the utility model provides a kind of pin connector, and pegging graft with a socket connector cooperates, and comprising: plug casing offers some plug end pilot trench that vertically run through plug casing inside; Plurality of conductive terminals is contained in the corresponding plug end pilot trench, and each conducting terminal cross section is bigger, has first substrate, and first substrate extends back first weld part, extends first contact site forward; And plurality of elastic terminal, also be contained in the corresponding plug end pilot trench and be positioned at described conducting terminal top, each flexible terminal cross section is less, have second substrate, second substrate extends to form a forearm forward, and front arm tip oppositely is bent to form an arched arm backward, arched arm front end and forearm junction form the top, to replace with the corresponding terminal of described socket connector, the arched arm bottom forms second contact site, to replace with first contact site of described conducting terminal.

As mentioned above, the utility model provides this pin connector and described socket connector to carry out signal required transmission path of when transmission by the bigger conducting terminal of cross section, required elasticity is replaced power when providing this two connector to peg graft by the less flexible terminal of cross section, thereby, provided thus between two connectors really, electrically conducted reliably in guaranteeing that signal stabilization transmission time and the elasticity that reduces between two connectors replaces power.
