Embodiment
Below in conjunction with embodiments some shown in accompanying drawing to the utility model based on theory be described further:
Fig. 1 illustrates the embodiment of one plugging type connector, and this plug-in connector has as the contact element 1 of the first plug-in connector parts and the corresponding contact element 2 as the second plug-in connector parts.Contact element 1 can be such as the part of charging plug, and corresponding contact element is the part of the charging socket for described charging plug insertion of attaching troops to a unit.But this embodiment is not formed restriction of the present utility model.In principle, contact element 1 and corresponding contact element 2 can be the parts of the distinct execution mode of plug-in connector parts.
Contact element 1 has the socket 11 that can insert along direction of insertion E by contact pilotage 20 for corresponding contact element 2.Contact pilotage 20 through rounding, therefore can be inserted socket 11 by most advanced and sophisticated 200 by the tip 200 of contact pilotage 20 easily, and snaps in socket 11 in the mode inserting rear generation electrical contact.
Contact element 1 has a cylinder segment 14, and some contact chips 12 extend from this cylinder segment along direction of insertion E.Contact element 1 integral type contact 10 is made, and the contact chip 12 of cylinder segment 14 and extension from this cylinder segment is the part of this contact.
Contact chip 12 is spaced by some gaps 13.
Contact 10 such as can be made by brass or another electric conducting material (such as copper) integral type.
Fig. 2 A to 2D is the different execution modes of the contact element 1 comprising contact 10 in a state of nature.The concrete manufacture of contact element 1 is: in originally for columniform contact 10, arrange the socket 11 being embodied as boring.By arranging gap 13 by spaced for contact chip 12, thus produce the contact 10 be in its reset condition as shown in Fig. 2 A to 2D.
