Definitions

  • the present invention relates to a contact sleeve for electrical plug devices according to the preamble of claim 1.
  • Plug devices of this type are known from DE 93 05 881 and US 4 985 004 A and have a stamped, sleeve-shaped contact body which has a diameter constriction in one area.
  • the narrowing of the diameter results in a contact plane normal to the axis of the contact sleeve.
  • this results in two to four undefined contact points along the narrowing of the diameter.
  • it is always very important to have precisely defined contact points. For example, the thermal load is different if only two are available instead of four contact points.
  • the narrowing of the diameter also forms an inner bulge which, in the case of heavily soiled contacts, helps to ensure that contact safety is no longer ensured.
  • Contact sleeves are also known which are manufactured from solid round material by drilling and slitting.
  • the contact elements are produced by multiple, usually six times slitting of the sleeve, which provide contact security by means of an additional, separately attached spring with radial effect on the spring elements.
  • the problem of creating a precisely defined contact zone also arises here.
  • the manufacturing-related offset of the bore diameter in the contact sleeve and the not always the same position of the slots result in different spring elements with an inhomogeneous mode of action on the plug pin. Complemented by normal wear and tear. This results in undefined contact points and high contact uncertainties during the plugging and pulling process.
  • contact sleeves are known, the base body of which is produced from a full round material and a resilient contact lamella is manufactured separately as a stamped part and the Basic body is fed.
  • this type of production is very complex to produce and therefore leads to high production costs.
  • the special display of the contact elements from the sleeve jacket creates at least one defined contact point at which the electrical current is transmitted from the contact sleeve to the plug pin.
  • the display of three contact elements results in three defined contact points and the plug pin is additionally centered when the same is inserted.
  • the distribution of the contact elements over the sleeve according to the characterizing features of claim 2 enables an additional improvement of the contact.
  • the contact zones are cleaned during the insertion of the plug pin into the contact sleeve. Any dirt that would adversely affect the contact can thus be removed before the end position of the plug pin in the contact sleeve is reached.
  • the guide section enables the plug pin to be inserted easily into the contact sleeve, with the contact elements being slightly pushed apart radially.
  • the features of claim 4 allow precise centering of the connector pin. Due to the features of claim 5, a radially inward pressure is exerted on the contact elements, by means of which pressure is pressed onto the plug element. This ensures that even after repeated insertion and removal of the connector pin in the contact sleeve, the contact elements are pressed sufficiently firmly onto the connector pin.
  • Fig.l is an axonometric view of a contact sleeve
  • FIG. 3 shows an axonometric view of a contact sleeve with a spring ring
  • FIG. 5 shows an axonometric view of an alternative embodiment of a contact sleeve
  • FIG. 6 shows a further axonometric view of an alternative embodiment of a contact sleeve
  • Fig.l shows a one-piece stamped and bent part 1 whose front section is bent into a sleeve-shaped contact element 2 and one end portion of which forms a flat tapered connecting part 3, which enables connection to the intended conductor by means of additional clamping elements (not shown).
  • the sleeve-shaped contact element 2 has two regions spaced apart in the axial direction of the sleeve (Contact planes) 4a, 4b, in which parts of the sleeve jacket are cut free or punched out and bent inwards and thus form precisely defined contact elements 5a-5c, 6a-6c (see also FIG. 2).
  • Three contact elements are preferably provided. However, one or more than three contact elements can also form the defined contact points.
  • the contact elements can spring through the free cutting or punching in the radial direction of the sleeve.
  • Each individual contact element 5a-5c, 6a-6c has a guide section 7a, 7b and a contact edge 8a, 8b
  • the guide section is first arranged in the insertion direction 11 of the plug pin, not shown, and has a guide edge inclined to the axis of the contact sleeve 2 and converging thereon.
  • the subsequent contact edge forms an edge aligned parallel to the axis of the contact sleeve 2.
  • the clearances or free punchings visible in the sleeve casing serve to improve the spring action of the contact elements 5a-5c, 6a-6c in the radial direction.
  • the contact sleeve 2 furthermore has on the outside thereof in the area of the inwardly projecting contact elements 5a-5c, 6a-6c in each case a groove 10a, 10b which extends over the circumference of the contact sleeve 2 and which is provided for receiving an additional annular spring element 9a, b is.
  • the mode of operation of the contact sleeve 2 can be described as follows: When the cylindrical connector pin (not shown here) is inserted, the tip of the connector pin meets the guide edges 7a of the contact elements 5a-5c and is centered on these edges, as a result of which a defined three-point support of the contact plane 4a is created becomes. As the depth of penetration progresses, the cylindrical contact pin radially pushes the individual contact elements 5a-5c apart, the force of the additional spring element 9a counteracting the expansion as a spring force. When the straight contact edge 8a is reached, the contact pin is pushed under permanent pressure of the additional one Spring element 9a parallel to the axis and linearly over the contact edge 8a of the contact elements 5a-5c. By pushing the plug pin over the contact elements 5a-5c, the contact edge 8a is self-cleaning.
  • This contacting process is repeated in the subsequent contact plane 4b, with the difference that the individual contact elements 6a-6c are arranged radially offset from the contact elements 5a-5c of the contact plane 4a and thus represent a completely independent further contact plane (see FIG. 2).
  • FIG. 5 and 6 show an alternative form of a contact sleeve according to the invention.
  • the contact elements 5a, 5b; 6a, 6b are cut out of the sleeve casing to such an extent that it is practically in an area 12 with the contact elements 5a, 5b; 6a, 6b is identical.
  • this has the additional advantage of increased elasticity of the contact sleeve, which makes the system insensitive to inaccurately fitting plug pins.
  • the webs marked with 13 are anti-rotation devices which position the contact sleeve according to the invention in a chamber of a plastic contact carrier (not shown).

Abstract

L'invention concerne un connecteur femelle pour dispositif de raccordement électrique, comportant un élément de contact (2) en forme de douille pour réceptionner une pointe de contact, et une pièce de raccordement (3), de préférence plate, disposée dans la prolongation axiale d'une extrémité de l'élément de contact pour le raccordement de conduites électriques. L'invention vise à réaliser une douille de contact de fabrication aisée et dotée de points de contact définis de manière précise pour assurer un bon contact. A cet effet, au moins sur un niveau (4a, 4b) perpendiculaire à l'axe de la douille (2), celle-ci est pourvue, sur au moins un emplacement et de préférence sur trois emplacements, d'éléments de contact (5a-5c, 6a-6c) espacés vers l'intérieur et dégagés sur trois côtés hors de l'enveloppe de douille. Ces éléments de contact sont disposés de façon décalée sur différents niveaux (4a, 4b) perpendiculaires à l'axe de la douille (2), sur le pourtour de ladite douille.
