Electrical plug connection

The invention relates to an electrical connector, consisting of a socket contact and one in this with electrical contact axially insertable pin contact according to the preamble of protection claim 1 »

Such a plug connection has become known from German patent application DE-OS-22 18 751. In this plug connection, both contacts, socket and pin, are radially expandable due to the arrangement of longitudinal slots, one in the socket and four longitudinal slots in the pin in the contact area. With a corresponding material thickness, this arrangement leads to high push-on forces without the electrical contact being significantly improved.

The invention is based on the object that

Plug connection according to the state of the art so |

to improve that on the one hand the slip-on j

forces are low, on the other hand the elec- »

tric contact is improved so that |

I higher currents can be transmitted.

This actually contradicting goal is achieved in a surprising manner by the invention characterized in protection claim 1, with the further protection claims
represent advantageous embodiments of the invention. The training according to protection claim 9 shows a plug connection with a particularly high current-carrying capacity.

FIG. 2 shows the plug connection according to FIG. 1 in plan view and with the contact area broken away.

FIG. 3 shows a partial view according to FIG. 1. FIG. 4 shows the section A-A in

Figure 3, but without pin contact.

The pin contact 1 is pushed into the socket contact 2. Both parts are stamped and bent parts manufactured *

The pin contact 1 comprises a conductor claw 3 and an insulating claw 4 for connection to an electrical conductor, not shown, by means of the crimping technique or the like. A holding area 5 adjoins the ladder claw 3, which has a stop collar 6 and includes two punched-out retaining lugs 7. The holding area 5 is used for lockable storage of the pin contact 1 in a connector housing, not shown.

The actual tubular Koht-Aktbereich 9 of the Stiftköntäktes 1 connects via a conical tapering section 8. The sections or parts with the Bezuys numbers 3 to 9 are made of tin-plated CUFe2 sheet metal . The inner liner 10 is made of Ver-zinntem CuCoBe sheet metal and comprises two tubular rim portions 11 and a plurality of axially disposed between this · after innsn deflected Kon clock fins 12 alternating '} with slots. 13

The inner sleeve 10 is adapted to the inner diameter of the contact area 9 with slight radial play (sliding fit). In the axial direction, the inner bushing 10 is held on the inside by an annular bead 14 and on the outside by a curl 15 at the end of the contact area 9, with a small axial clearance S ^ for
the socket 10 remains, which is reduced by the plugging together.

The socket contact 2 also comprises a jj O conductor claw 3 ¹ and an insulating ^{claw 4 1}

for connection to an electrical conductor. A retaining collar is attached to the ladder claw 3 ' 6 ', on which the tubular contact area 16 of the socket contact 2 adjoins. Inside the Contact area 16 is mounted a central inner pin contact 17, which is chamfered via a Head plate 18 is anchored in the region of the retaining collar 6 '. The inner pin contact 17 extends through the inner socket 10 and forms the first via the contact blades 12 Current path.

'Outer sleeve 19 with radial and axial play with a sliding fit. Axially the outer sleeve 19 is held inwardly by the head plate 18 and outwardly by sheared lugs 20. The outer socket 19 is supported on the contact area 9 of the pin contact 1 via a large number of lamellas, between which slots are arranged, as described for the inner socket OK, and forms the second current path; The tabs 20 are sheared radially outward from the socket 19 and engage in recesses 21 in the contact area 16 of the socket contact 2. Since the recesses 21 are arranged on both sides of the longitudinal slot 22 of the socket contact 2, this causes? When the tabs 20 engage, a rigid bridging of the longitudinal slot 22 in the sense of a closure of the socket contact 2, which is now prevented from radial expansion when the pin contact 1 is inserted. An insertion funnel 23 arranged on the outer socket 19 serves to facilitate the insertion of the pin contact 1.
