Definitions

the invention relates to a contact piece for a electrical connector according to the preamble of claim 1 and a process for its production.
Contact pieces of the type mentioned are particularly characterized in that its contact area is that for receiving a cylindrical contact pin - the contact piece corresponding counterpart of the connector - cage-like is formed, that is, as a plug-in direction longitudinally slotted hollow body is designed, which is preferably is additionally twisted in the circumferential direction. Especially in the latter case is therefore the contact pin in the inserted Safe condition on a plurality of strip-shaped slats of the contact piece, which is why this type of connector safe even with relatively high electrical loads can be used.
a solution to this problem is known from WO 98/43321.
a contact for an electrical connector of the type mentioned discloses a connector. This is formed in one piece and in particular as made a stamped part that after the stamping process in the predetermined shape of the socket is bent.
several tongues are provided, which at the outer end the contact area of the plug socket immediately are scheduled. These tongues are around the outer end of the contact area bent around 180 ° so that it covers the outer surface form the socket in the contact area. These tongues serve to strengthen the contact area because one has obviously recognized that this and in particular the relatively sensitive twisted slats have to.
the present invention is therefore based on the object for a contact piece of an electrical connector to create a further embodiment, which are inexpensively manufactured in large series production can be, the effort for the punching and bending processes reduced and a dimensionally stable product technologically controllable to achieve with simpler tools is.
This solution has the advantage that the contact piece itself is very simple.
One is foreseen Contact element with the connection area on one and the actual contact area at the other end.
This is electrical considered, advantageous simply because in this If there are any problems with electrical contact resistance due to tolerances, mismatches and the like can occur between several components.
this contact element as a stamped and bent part can be made from a strip material. That remains the individual contact element - strapped across - on one at Punch out the remaining margins of the original Tape material hanging, what its further processing in the Series and essential simplified. The only assembly step is on the contact area of the already completed Press the contact sleeve the protective sleeve. Also for later processing until the assembly of the Plug connector remains strapped crosswise on his Carrier strips.
the socket part of the contact element one at each end of the contact area circumferential inner or outer flange, furthermore the Protective sleeve designed as a thin-walled hollow cylinder, which lies on the circumference of the inner flange with a press fit, compared to the circumference of the outer flange, however Match fit.
the protective sleeve and contact element with each other simply, mechanically are securely connected.
the socket part in the protective sleeve sufficient Play to yourself when inserting a contact pin to be able to deform elastically. This not only reduces the necessary insertion force, but also increases the electrical Operational safety, so leaves a high one without malfunction Number of mating operations too.
the contact piece according to the invention is distinguished also in that it is in accordance with the single procedural claim also on a simple one, for mass production suitably essentially as a stamped and bent part create and edit well in intermediate steps is because it is strapped crosswise with other contact pieces at predetermined intervals on a serving as a carrier Edge band of the original band material is set. Shipping is also carried out in this machine-compatible condition to the customer who does the actual connector assembly himself makes.
a in Figure 1 in a partially cut side view shown contact piece 1 for an electrical Plug connection has a connection area at one end 11 and the other end facing away from a contact area 12.
the contact piece 1 is composed of two components. One of these components is a contact element 2. As will be shown in more detail below, this is a Stamped and bent part made from a flat strip material.
this is a Stamped and bent part made from a flat strip material.
the contact element shown in FIG. 1 2 is for connecting a not shown electrical conductor provided a crimp connection.
To the contact element 2 in the connection area 11 has two pairs of connecting tabs bent upwards, between the the electrical conductor, not shown, when connecting is inserted.
connection tabs the actual crimp contact 21, from which, after crimping, the stripped free end of the shown electrical conductor is enclosed. That too external pair of connection tabs is used during the crimping process around the protective sheath of the electrical conductor, not shown bent around and thus serves as a clamp connection 22, the electrical conductor, not shown, on the contact element 2 mechanically determines that the electrical Connection in the area of the crimp contact 21 strain relieved is.
the contact element 2 has a socket part 23 on that for receiving a schematically shown Contact pin 3 of the electrical connector designed is.
the socket part 23 is as one cylindrical hollow body formed in the contact area 12 a flange 24 or 25 at both ends having. Between these two webs 24 and 25 is the socket part 23 parallel to the axis, that is, along the direction of insertion of the contact pin 3 slotted. It owns thus a plurality of web-like slats 26, which in the Final state of the contact element 2 by turning the two Flanges 24 and 25 of the socket part 23 twisted against each other are.
the twisted fins 26 of the socket part 23 are due to this torsion process in the form of hyperbolic surfaces arched inwards and in their entirety form one Plenty of local contact points when plugging in of the contact pin 3 in the socket part 23 on its circumference apply under elastic pretension.
This contact principle is well known in itself, so here is an even more detailed one Explanation for understanding no longer required is. Further details of the present embodiment are explained below in the given context.
the described socket part 23 of the contact element 2 is in mechanically a relatively sensitive structure. It must not be deformed during transport and assembly processes or otherwise damaged, on the other hand, should be permanently elastic to be even in spite of a possible variety of mating operations to function electrically safely and without errors.
the second component of the contact piece 1 is a thin-walled one Protective sleeve 4 provided over the contact area 12 of the contact element 2 is pushed.
Figure 2 illustrates that the protective sleeve 4 on her one, in the assembled state on the inner flange 24 of the Contact element 2 pushed end 41 a little has reinforced wall. This wall reinforcement serves the protective sleeve 4 with a press fit on the inner flange web 24 to be able to slide on the contact element 2.
This dimensioning of the protective sleeve 4 in relation to has the outer diameter and the length of the socket part 23 the purpose of a defined elastic deformation of the socket part 23 to allow for mating processes. So that is Protective sleeve 4 by the press fit on the inner flange 24 of the Contact element with respect to the socket part 23 of the contact element 2 defined and mechanically fixed and still allowed within a permissible tolerance range occurring elastic deformations of the socket part 23 of the Record contact element 2.
FIG. 4 it is shown on the basis of a sectional view that for the described contact element 2 as a starting material Tape material is used from which the individual contact elements 2, cross strapped, punched out.
Tape material is made up of electrical contacts made of a Cu-Sn alloy, its surface in the course the manufacture of the contact elements 2 electroplated becomes. For example, one is initially used as the adhesive layer Nickel layer, then a gold layer and optionally one covering tin layer applied.
the sectional view of the contact elements 2 shown in FIG. 4 clarifies that this at a predetermined pitch t on one when punching out the contours of the contact elements 2 stationary carrier strips 5 to its longitudinal direction set transversely over a narrow fastening web 51 are.
connection area 11 of the contact elements 2 scheduled.
FIG Connection tabs for the clamp connection that face outwards in pairs 22 and the pinch contact 21.
the contact area closes at the top 12 with the inside flange 24, the cut Slats 26 and the outer flange 25 of the socket part 23 on. Both flange webs 24 and 25 face each other in pairs each assigned a locking lug 27 or a locking recess 27 'on.
the inner flange 24 of the contact element 2 has Furthermore, one lying on the longitudinal axis of the contact element 2 Fixing bore 28 on, while the outer flange 25 on its outer edge a pair of groove-shaped Has edge slots 29. The function of these items 27 to 29 of the socket part 23 of the contact element 2 are explained in more detail below.
the contact elements 2 When manufacturing the contact elements 2, these are first corresponding to the sectional view shown in Figure 4 punched out of the strip material. Hanging on the carrier strip 5 the contact elements 2 are then in the already mentioned Wise surface finish. Then locks up Bending and rolling process in which the contact elements 2 in Connection area 11 bent from both sides or in Contact area 12 are rolled. Add in this rolling process detents 27 assigned to each other in pairs or locking recesses 27 'in each other and fix thus the socket part 23 in the circumferential and longitudinal directions. In order to then twist the socket part 23 to be able to, the fixing hole 28 is provided on the one hand.
the inner flange 24 of the twisting socket part 23 by means of a inserted therein Bearing pin of a twisting tool against twisting in Circumferential direction secured.
the real twist of the Socket part 23 is with a blade-like rotary part of the Twisting tool performed because with its tip in Direction of insertion on the outer wall of the outer flange 25 is brought up and into the groove-shaped edge slots 29 intervenes.
By turning the rotating part of the twisting tool permanent twisting occurs at a defined angle of the socket part 23 preferably by, for example, 10 ° relative to its stretched location.
