Definitions
- the invention relates to a plug part for an electrical plug connection according to the preamble of patent claim 1.
- an electrical connector equipped with a protective conductor contact which consists of a two-part insulating body that receives and holds a number of contact elements and a metallic outer housing that accommodates this.
- the contact elements connected to the associated electrical lines are fixed in the insulating body by plugging the two parts into one another.
- a device permanently arranged in the outer housing of the plug housing which automatically contacts when the contact element of the protective conductor is inserted into the insulating body and which produces an electrically conductive connection to the outer housing.
- the device is formed by a radially expandable spring sleeve which is arranged coaxially with the protective conductor contact in the insulating body and by means of radially directed webs which are connected to the spring sleeve and are curved coaxially to the longitudinal axis of the plug housing.
- the spring sleeve contacts the inner circumferential surface of the outer housing via the spring clip.
- the invention is therefore based on the object of developing a plug part of the type mentioned at the outset in such a way that a safe and simple electrically conductive connection between the plug housing and the protective conductor contact can be ensured with simultaneous current transmission.
- the object is achieved according to the invention by a plug part of the type mentioned at the outset with the features of the characterizing part of patent claim 1.
- the protective conductor contact makes direct electrical contact with the plug housing
- additional intermediate connecting means between the protective conductor contact and the plug housing are dispensed with, thereby reducing the Installation effort is limited to the insertion of the protective conductor contact.
- the direct contacting according to the invention increases the contact reliability between the protective conductor contact and the plug housing, which improves the overall safety of the plug part when the insulating body burns down.
- the protective conductor contact has contact springs which are turned outwards and bear on the connector housing under bending stress. This achieves a contact force that is reproducible in terms of production technology and can be defined in a defined manner via the material and structural design of the contact springs.
- the contact springs extend approximately in the plug-in direction and are arranged in a rotationally symmetrical manner with respect to a central axis of the protective conductor contact.
- the contact springs under bending stress each generate a force directed towards the central axis of the protective conductor contact, which, due to the symmetrical arrangement of the contact springs, the protective conductor contact in a cylindrical recess receiving the latter centered.
- the centering effect largely eliminates a so-called insertion during the plug-in process, that is, insertion of the pin contact of a mating plug into the annular gap outside the socket contact and within its recess receiving it.
- the protective conductor contact has a sleeve part with webs which extend parallel to the central axis between two end rings at the end, at least part of the webs being designed as contact springs.
- the part of the protective conductor contact which has the contact springs can be produced separately in terms of production technology and then firmly connected to the other part of the protective conductor contact, so that the protective conductor contact can be inserted completely into the plug part with integrated contact springs.
- the sleeve part also exerts a reinforcing effect on the area of the protective conductor contact over which it extends, and a protective effect for any sensitive areas of the protective conductor contact arranged within the sleeve part.
- the contact springs are connected at least to the plug-side end ring. Regardless of whether the externally parked contact springs are only connected to the plug-in end ring in an open configuration or also to the conductor-side end ring in a closed configuration, this measure ensures easy and safe insertion of the protective conductor contact into the plug part. Since the plug-side end ring of the sleeve part, with which the contact springs are at least connected, precedes the conductor-side end ring when the protective conductor contact is inserted, the contact springs do not act as Barb, but slides resiliently over the edges of the recess in the plug part that contacts the protective conductor contact.
- the contact springs are not connected to the conductor-side end ring and their free ends are curved inwards.
- the bend at its free ends creates an outwardly facing convex surface that serves as the defined contact surface of the contact springs on the connector housing.
- the rounded shape of the free ends of the contact springs prevents additional hooking when inserting the supporting conductor contact, so that the inserted protective contact piece can perform its function undamaged.
- the plug housing has a bore which receives the protective conductor contact and on whose inner wall the contact springs bear.
- the connector housing preferably designed as a cast metal part, takes the in its bore in this way
- FIG. 1 shows a partial section of a plug part according to the invention in the area of the protective conductor contact
- Protective conductor contact in perspective. 1 in a partial section for a detachable electrical plug connection comprises a number of electrically conductive contact pieces, in particular a protective conductor contact 1, which can be inserted into cylindrical recesses 2 of an insulating body 3 provided for this purpose.
- a mother plug-in part is shown here, in which the contact pieces, in particular also the protective conductor contact 1, are designed as socket contacts.
- the cylindrical recesses 2 and these through holes 4 in the insulating body 3 which extend on the plug side extend in the plug-in direction S.
- the insulating body 3 which receives the contact pieces 1 is arranged in an outer metallic plug housing 5 with a union nut 6 which can be freely rotated relative thereto.
- connection When the connection is elongated, through the through holes 4 of the insulating body 3, pin contacts, not shown, designed as mating contacts of a mating connector, also not shown, protrude, which are received by the contact pieces designed as socket contacts for producing an electrical contact.
- the union nut 6 of the nut part can be screwed to an external thread formed on the associated father part.
- One of the contact pieces, the only one shown here, serves as a protective conductor contact 1 and is therefore connected to the metallic connector housing 5 in an electrically conductive manner. This is achieved according to the invention in that the protective conductor contact 1 makes direct electrical contact with the plug housing 5.
- the protective conductor contact 1 has contact springs 7 which are turned outwards and which bear against the plug housing 5 under bending stress.
- the plug housing 5 has a bore 8 which receives the protective conductor contact 1 and on the inner wall 9 of which the contact springs 7 rest due to their bending stress.
- the contact piece 1 is composed of a socket part 12 and a sleeve part 13 firmly connected thereto.
- the socket part 12 is made as a stamped or bent part from a flat strip material.
- a crimp connection is provided for connecting the contact piece 1 to an electrical conductor (not shown).
- the socket part 12 in the connection area 10 has two pairs of connection lugs each bent upwards, between which the electrical conductor (not shown) is inserted when connecting.
- the wider, inner pair of connection lugs forms the actual crimp contact, from which, after crimping, the stripped free end of the electrical conductor (not shown) is enclosed.
- the outer pair of connection tabs is also bent during the crimping process around the protective sheath of the electrical conductor (not shown) and thus serves as a clamping connection which mechanically fixes the electrical conductor (not shown) on the socket part 12 of the contact piece 1 in such a way that the electrical connection in the region of the Squeeze contact is strain relieved.
- the socket part 12 is designed as a cylindrical hollow body which, in the contact area 11, as shown schematically in FIG. 1, has a plurality of web-like lamellae 14, which are formed in shape by rotating the socket part 12 in the contact area 11 about a central axis 15 of the contact piece 1 hyperbolic surfaces are curved inwards and in their entirety forms a large number of local contact points which, when a contact pin is inserted into the socket part 12, lie on the circumference thereof under elastic prestress.
- the sleeve part 13 is pushed over the socket part 12 in order to reinforce and protect the lamella 14 in the contact area 11 and is firmly connected to the latter, for example by laser welding.
- the contact springs 7, which are turned outwards, are fixed and extend approximately in the plug-in direction S, so that the contact piece 1 easily and without risk of the contact springs 7 getting caught in its recess 2 in the insulating body 3 or through the bore 8 in the connector housing 5 is insertable.
- the sleeve part 13 of the contact piece from FIG. 2, which is designed in particular as a protective conductor contact 1, has two end rings 16 and 17 between which 15 webs extend parallel to the central axis, at least some of the webs, in the exemplary embodiment shown three, as contact springs 7 is trained.
- the webs designed as contact springs 7 are firmly connected to the plug-side end ring 16 and are bent inwards at their free ends 18 facing the conductor-side end ring 17.
- the three contact springs 7 are placed radially outward with respect to the central axis 15 at an angle of approximately 3 ° to 10 ° and are distributed in a rotationally symmetrical manner, namely offset in the circumferential direction by an angle of 120 ° in each case.
- a web Arranged between each two contact springs 7 is a web which firmly connects the end rings 16 and 17 and is designed as a supporting wall 19 of the sleeve part 13.
- the contact piece according to the invention enables the electrical contact to corresponding mating contacts of a mating connector of the electrical plug connection via a pin-socket contact for proper appropriate current or signal transmission can be produced.
- the sleeve part which has the contact springs has only a centering function apart from the protective and reinforcing effect.
- electrical contact can be made directly via the contact springs of the sleeve part to the plug housing, for example, as a metal casting.
- one and the same contact piece can be used for each of the poles of the plug part according to the invention in a cost-reducing manner.
