Definitions
- the invention relates to a contact piece for an electrical Plug connection according to the preamble of the 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, 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.
- the patent US 5,921,822 discloses a female end piece a connector according to the preamble of claim 1 with clamping sections for one Wire and its sheathing and with a cylindrical Contact section.
- the contact section has a rear and a front hexagonal end ring between which three or five contact rods or springs extend.
- a protective hood is arranged over the contact area.
- the publication FR 2 754 639 A1 discloses methods for Manufacture of socket contacts for electrical plugs, the a tubular contact area for receiving a contact pin and a connection area for an electrical Have conductors.
- a number of lead wires are attached, which forms an elastic cage for the contact pin.
- a sheet metal part is punched out in the form of a parallelogram, of which an elongated strip along a central axis protrudes.
- the row of lead wire pieces attached at their ends On one side of the sheet metal part is parallel to its central axis, the row of lead wire pieces attached at their ends.
- the parallelogram rolled up into a hollow cylinder, the on their End pieces of wire attached to the surface of a single-shell Nestle hyperboloids.
- the hollow cylinder forms the contact area, while the strip the connection area of the socket contact.
- 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. There is only one 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. It is advantageous further that 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 significantly simplified. The only assembly step is there in it, on the contact area of the already completed Contact element to press the protective sleeve. Also for later further processing until the assembly of the The connector remains taped across its carrier strip.
- 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 Match to become elastic when inserting a contact pin to be able to deform. 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 stands out also characterized in that it is according to the only procedural claim also on a simple one, for mass production suitably essentially as a stamped and bent part lets create and edit well in intermediate steps is because it crosses with other contacts taped at predetermined intervals on a serving as a carrier Margins of the original tape material set is. It also happens in this machine-compatible condition for shipping to the customer who does the actual connector assembly itself.
- 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 at 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 illustrated 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 illustrated 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 has a flange 24 or 25 at both ends.
- the socket part is between these two flange webs 24 and 25 23 parallel to the axis, that is, along the direction of insertion of the Contact pin 3 slotted. It therefore has one A plurality of web-like lamellae 26, which in the final state of the contact element 2 by turning the two flange webs 24 and 25 of the socket part 23 are twisted against each other.
- the twisted slats 26 of the socket part 23 are through this torsion process in the form of hyperbolic surfaces arched inside and form a multitude in their entirety from local contact points that occur when the contact pin is inserted 3 in the socket part 23 at its circumference Apply elastic pre-tension.
- This contact principle is on well known, so here is an even more detailed one Explanation for understanding is no longer required. Further Details of the present embodiment will be given in the following 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, should on the other hand be permanently elastic to be 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 its one, in the assembled state on the inner flange 24 of the Contact element 2 pushed end 41 slightly has reinforced walls. 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.
- FIG. 4 it is shown on the basis of a sectional diagram that for the contact element 2 described 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 over 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 illustrates that this is 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. At this is the connection area 11 of the contact elements 2 scheduled.
- 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.
