Definitions
- the invention relates to a plug contact element for producing an electrically conductive one
- Connection comprising a crimping section for producing an electrically conductive
- connection with a line and at least one plug contact mandrel for establishing a detachable electrically conductive connection with a contact box.
- Socket or plug contact elements can be designed as crimp contacts.
- crimp contacts are designed as elements with tabs, the tab ends of which are bent around the electrical conductor and at the same time pressed with it. This available
- connection technology is known as crimping.
- Compression processes are often impressed on a semi-finished product that has been prepared for this purpose, which is available as an uncrimped or pre-crimped starting material and which later forms the contact element.
- the semi-finished product is often placed on the anvil of a crimping tool.
- the electrical conductor or a stripped section of the electrical conductor is then placed on the contact element.
- the at least one crimp tab is bent around the stripped section and pressed with it in order to produce a mechanically stable and electrically conductive contact between the contact element and the electrical conductor.
- crimp connections Depending on the area of application, different, sometimes cumulative, requirements are placed on crimp connections. Examples: mechanical strength, fatigue strength, low-resistance transmission of electrical energy, corrosion resistance, gas and liquid tightness.
- mechanical strength In addition to the crimp contacts with their functional task, supply lines, cables or
- Known methods for producing contacting components are, in particular, stamping and forming processes.
- a sheet is separated from a sheet metal sheet or sheet material by a punching step or, more generally, by a separation step.
- the flat is provided in a suitable manner with contours that shape towards the
- the flat semi-finished product made available in this way is then further developed in one or more forming steps. Possible forming processes can be implemented by folding, edging, pressing, deep drawing or the like.
- the combination of the punching and reshaping of a flat starting material is an economical and reliable way to provide contacting components in large numbers, but limits the integration of various functions in one-piece contacting components and in particular socket contact elements due to the restricted geometric shape.
- plug-in contact elements have disadvantages that include economic production, plug and / or contact reliability, mechanical strength, structural integrity, fatigue strength, shock and / or vibration resistance, corrosion resistance,
- the invention proposes a one-piece plug contact element for making an electrically conductive connection, which is equipped with a crimp section for making an electrically conductive connection with a line and a plug contact, contact blade, plug contact mandrel for making a detachable electrically conductive connection with a contact box. Furthermore, the invention proposes an arcuate semifinished product for the production of a plug contact element and the production method by forming.
- the invention recognizes that the geometric complexity of the flat material as a semifinished product for one-piece plug contact elements and / or the forming sequence is suitable for at least partially reducing the disadvantages present in the prior art and also providing further advantages.
- the invention proposes, starting from a curved flat material with an edge geometry adapted to the plug contact element, to generate a contact design, preferably by forming, that in the plug zone, ie in the area of the plug contact, contact blade, plug contact mandrel, a sandwich fold is sufficient with the result that the plug contact cross section after the Folding is three times the thickness of the material.
- the cavity formed on the inside by the contact blade geometry is, according to the invention, filled or occupied by a tongue, so that the outer material of the plug contact mandrel is supported on the inside.
- Triple material strength and / or supporting effect increase the strength significantly.
- Crimping section or section for cable fixing are integral parts of the
- the first connection is realized by the contact blade outer area, the second connection by the tongue element. This double connection results in a high stability of the structure and the
- the invention preferably provides that a symmetrical fold and a symmetrical cross section are formed in the contact knife area. This means that the tongue is axially or point-symmetrically encompassed by the outer contact blade area.
- the joint of the outer material is preferably located in a plane of symmetry. Designs deviating from the symmetrical geometrical situation are also from the
- the construction supports the one-piece design of the plug-in contact element, so that this can be produced by a circuit board, arcuate flat material with an outer edge geometry according to the invention. This also results in the advantage of efficient, high-volume manufacturing.
- the plug-in contact element is implemented in a sandwich fold so that the strength of the plug-in element as well as of the overall component is increased due to the triple or two- and / or three-layer material structure.
- the double connection situation of the contact blade to the plug contact element increases the strength and structural integrity significantly.
- the outer material of the plug contact mandrel is folded around the inner tongue element so that very small corner radii can be formed in the folded areas. In this way, the invention supports an increased surface with a flat expression of the plug contact pin, which is preferably square in cross section and which is available as a contact surface. The result is an increased contact area, so that the contact quality for the electrically conductive connection is increased.
- FIG. 1 a, 1 b a perspective view of an exemplary embodiment of the
- 3a, 3b are further perspective views of the exemplary embodiment of the
- FIG. 1a comprises the perspective view of an exemplary embodiment of the plug contact element 100 with its various sections 10 to 60 as well as the contact blade 90 fixed on the contact box 70 via the connecting section 80.
- the primary elements of the plug contact mandrel 90 are the inside tongue 91 and the
- FIG. 1 b shows the plug contact area 90, shown enlarged, with contact boxes 70, which are coupled to one another by the connecting section 80. Both that
- Contact knife 90 with its primary components tongue 91 and outer area 92 as well as their connecting section 80, formed by their respective connecting tabs 81, 82, are constructed in one piece on a semi-finished flat 100 '.
- Contact blade outer area 92 comprises, preferably implemented by the
- This joint 93 can be designed with or without an air gap.
- the outer contact blade area 92 can have a radius, bevel 94 on at least one longitudinal edge and / or be deformed by a folding process.
- a bevel, tip 95 is optionally possible on the front side in order to support the threading into the counterpart of the plug contact 90.
- the end face 95 can be flush with the embraced tongue 91 or also set back and protrude over the tongue 91.
- Plug contact element 100 with connection section 80 to plug contact mandrel 90 The front view of the plug contact element 100 is shown in Figure 2b. The
- Tongue connection tab 81 of this embodiment is made waisted, i. H. in the longitudinal extension L in the direction of the contact blade 90, the strap width decreases. It is also possible to provide the tab with a constant width in the longitudinal direction L.
- Tongue connection tab 81 on contact box 70 and / or on tongue element 91 can be shaped in a soft arc, for example formed by radii, so that the
- the connecting tab 82 of the contact blade outer area can, as shown, also be tapered and spatially curved, in that it is formed both parallel out of the plane relative to the attachment on the contact box 70 and out of this plane.
- the invention preferably provides that the connecting tab 82 of the contact blade outer area on the
- Contact box 70 is designed partially circumferentially on its outer contour and / or partially circumferentially in the connection area to the contact blade outer area 92. In this way, the construction according to the invention achieves a special shape and flexural strength in this connection area, which is further increased by the interaction of the tongue connection tab 81.
- FIG. 3a illustrates the exemplary embodiment of the plug contact element 100 in two perspective views with differing spatial orientations.
- the longitudinal extent of the plug contact mandrel 90 is approximately the same as the longitudinal extent of the contact box 70
- Plug contact socket possible and supported by the invention.
- the three-dimensional plug contact area 90 shown enlarged compared to FIG. 3a, with connecting section 80 is the subject of FIG. 3b.
- Contact blade outer area 92 is shown in its three-dimensional extent.
- the contact mandrel tip 95 can be designed at least partially as a rounding R.
- Figure 4 shows the top view of a possible embodiment of the arcuate
- one-piece flat material 100 ‘as a semi-finished product for a plug contact element 100 after a contour-forming manufacturing step, for example a stamping process and before
- the geometric design of this example provides that the contact blade outer region 92 is designed with an offset to the longitudinal axis L. This offset and the distance to the tongue 91 realized in the transverse direction to the longitudinal axis L, together with the edge length of the contact box 70 to be molded, determine the type of enclosure of the outer contact blade area 92 enveloping the tongue 91.
- the variant shown supports the symmetrical folding with joint 93 according to FIGS 3.
- Folding situations require changes in shape and position in terms of connection area 80, stop positions of tabs 81, 82, width ratios of contact blade elements 91, 92 and the relationship of the contact box edge length.
- the deformation processes for the formation of the plug contact element 100 can be roughly divided into four zones of the semi-finished surface 100 ‘:
- the central area MB is not or only marginally deformed in the handling area 10 and in the area of the contact box 70, so that a substantially flat structure is obtained.
- the other areas there is a spherical or spatial deformation in different forms, for example in the manner of a cylinder section.
- the respective outer areas can be the subject of folding measures, folding processes or free deformations.
- the area of the contact box 70 can be any suitable material.
- the plug contact area 80, 90 is molded in: a. Centering of the tongue 91 in that the tongue 91 is at least approximated parallel to the longitudinal axis L of the central axis M with deformation of the tongue element connecting tab 81;
- Step b. can be supplemented by a centering of the outer contact blade area 92, which is required depending on the approximate centering of the tongue 91, by deforming its connecting tab 82.
