Definitions

  • the invention relates to a contact protection pin for a contact sleeve, having a shank and a tip at the end. Furthermore, the invention relates to a contact carrier with a contact protection pin and an electrically conductive, detachable plug connection with at least one such contact carrier.
  • plug connectors are used in a wide variety of configurations and variants.
  • Plug connection solutions are available in a large number of different designs, for example with regard to the number of poles, electrical performance and the conditioning of a wide variety of external influences such as moisture, temperature, corrosive media or mechanical loads.
  • Plug connections in particular in the area of high electrical power must, among other things, meet the highest standards of safety, reliability and personal protection. This applies not only to the intended use of the plug-in connections, but above all in situations during assembly, before plugging the connection together and last but not least with regard to unintentional disconnection of the plug-in connection or incorrect handling in general.
  • plug connections are known whose live elements and contact elements are insulated and/or provided with protection against accidental contact, so that the live components cannot be touched both when they are plugged in and when they are unplugged condition as well as in assembly situations is prevented.
  • DE 10 2018 127 720 B3 presents a high-current connector that has an insulating body.
  • the insulator has a polarization element to determine the orientation of the mating connector on the insulator, as well as a coding element to prevent incorrect connections.
  • the coding element can bring about a specific coding due to its position relative to the polarization element.
  • the plug contact in particular the pin contact, can have a protection against accidental contact at the free-standing end of its plug-in area, which consists of an electrically insulating material such as plastic.
  • the available, reduced contacting surface of the contact elements can be problematic with this contact protection solution.
  • each plug-in opening is provided with a protection against accidental contact. This contributes to a further increase in safety when handling the housing in the event of maintenance work and the like.
  • the contact protection is formed by the clear width of the plug-in opening and/or by a locking mechanism, in that the clear width of each plug-in opening is selected in such a way that the fingers of a service technician cannot get through the plug-in opening and touch a plug-in contact arranged under the plug-in opening.
  • a locking mechanism can be designed in the manner of a spring-loaded cover that automatically closes the plug-in opening, similar to a child safety lock. What is unfavorable with this solution is not only the limited accessibility due to the reduced clear width of the plug connection, but also the general vulnerability and reduced reliability of the locking mechanism with its moving parts. The cost-effectiveness is also unfavorable due to the expense for the moving parts.
  • a contact protection sleeve which, in the extended position, surrounds the current-carrying plug contact section so that it cannot be accidentally touched.
  • the contact protection sleeve is longitudinally displaceable in an insulating material housing, ie displaceably mounted in the insertion direction.
  • the contact protection sleeve has linear guide elements, which are arranged in a linear guide arrangement on the insulating material housing are stored and can be moved longitudinally therein.
  • the contact protection sleeve is subjected to a force by a compression spring arranged in the insulating material housing.
  • the compression spring is supported on part of the insulating housing, on a busbar or on a connecting section.
  • the contact protection sleeve is prestressed in the insertion direction by the compression spring. This contact protection solution is cost-intensive due to the large number of moving parts and not reliable with regard to the movement mechanics that are essential for the protective function.
  • WO 2013/091990 A1 describes a protection against accidental contact for electrically conductive connecting elements in an arrangement with a plug pin and a shield.
  • the connector pin is protected against accidental contact in the form of a non-conductive protective cap.
  • the non-conductive shield and the pin portion are separated by a slotted opening.
  • the technical teaching presented in the publication DE 102018 109 557 A1 relates to protection against accidental contact for an electrical connector on the plug-in side with at least two flat electrical contact elements arranged parallel next to one another, which are located in a housing of the connector in the plug-in direction of the connector for connection to a corresponding socket-side connector Connector extend towards an opening of the housing.
  • a plastic tip is formed at one end of a contact area of the contact elements, and at least one dome-like contact protection body is also provided in the housing, which extends adjacent to the contact elements in the plugging direction and has a predetermined height that corresponds at least approximately to the height of the contact area of the contact elements.
  • the height of the contact protection body can be such that the contact protection body protrudes beyond the contact area of the contact elements by a predetermined amount.
  • DE 202014 011 405 U1 shows a contact protection solution on the male side of a plug connection with an electrically conductive pin contact element, the contact protection solution of which is formed by a contact protection device that partially encompasses the pin contact element.
  • a contact protection device that partially encompasses the pin contact element.
  • contact protection pins can be used, ie a centrally arranged pin which extends inside the socket contact and protrudes in the axial direction of the socket contact. This prevents a user from reaching and touching the live inside of the socket contact.
  • the corresponding contact pin for realizing the electrically conductive connection with the contact socket must have an axial longitudinal bore, in which the pin, contact protection pin, can be accommodated when the plug connection is plugged in.
  • Such a contact protection pin is either made of plastic or metal with a plastic tip.
  • the contact protection pins are usually pressed or screwed into the connector housing. Configurations are also conceivable in which the contact protection pin is implemented as an integral part of a connector cover or the connector housing.
  • the contact protection pin is designed as an integral part of a connector cover manufactured by injection molding or of the connector housing based on a metallic material, the contact protection pin must, for example, be equipped with an insulating element at the end at its tip or at least partially have a non-conductive coating on its outer surface. It is the object of the invention to further develop the existing contact protection solutions for plug connections, connector systems in the form of contact protection pins and to improve them in such a way that the contact protection pin can be installed easily and reliably, high protection against contact is guaranteed and the disadvantages occurring in the prior art are at least partially reduced.
  • the invention proposes a contact protection pin that has a round flange at one end, through which the contact protection pin is clamped with its flange between socket contact, lamellar sleeve, contact sleeve in the receiving bore of the contact sleeve and with the shank of the pin protrudes through the contact sleeve on the inside.
  • the solution according to the invention not only provides a very simple and cost-effective construction, but the assembly is carried out safely and reliably in one operation and with only one press-in tool together with the pressing of the socket contact, lamellar sleeve, contact sleeve into the receiving bore.
  • the receiving bore can be within a contact carrier, a connector housing or a housing cover of the plug connection.
  • the contact protection pin with its end flange can be made entirely of an electrically non-conductive plastic and is preferably in one piece.
  • 3 shows the three-dimensional exploded view of the contact carrier
  • 4 shows the front view (left) and sectional side view (right) of the contact carrier with mounted contact sleeve, socket contact, lamellar sleeve and contact protection pin.
  • Figure 1 shows a perspective view of contact protection pin 1 with a tip 2 at the end and a flange 4 at the end opposite tip 2.
  • the actual pin body between the two ends is formed by a shaft 3, which preferably has a round cross-sectional area and is cylindrical. As shown here, the tip 2 can be rounded.
  • the area between the shank 3 and the flange 4 can have a recess 5 which reduces notch effects, i. H. Geometry-related stress peaks in the sense of internal material loads due to external forces are reduced.
  • flange 4 can be supplemented by a shoulder 6 .
  • FIG. 2 includes the three-dimensional representation of the contact carrier 10 with the assembled contact sleeve, socket contact, lamellar sleeve 11 and contact protection pin 1.
  • the contact carrier 10 has a receiving bore into which the contact protection pin 1 and the contact sleeve 11 are pressed.
  • FIG. 3 illustrates the three-dimensional exploded view of the contact carrier 10.
  • the contact protection pin 1 and the socket contact 11 are pressed into the receiving bore in the sequence shown.
  • Figure 4 shows the front view (left) and sectional side view (right) of the contact carrier 10 with the assembled contact sleeve, socket contact, lamellar sleeve 11 and contact protection pin 1.
  • the contact protection pin 1 protrudes beyond the front end of the contact carrier 10 in the axial direction by approximately one to two times its shank diameter and is arranged in front of the contact sleeve 11 in the direction of the blind hole of the receiving bore. To a good approximation, this also applies to the lamella sleeve 11.
  • the contact protection pin 1 is fixed by pressing with its concentric contact shoulder formed by a shoulder 6 and the flange 4 on the side of the contact protection pin 1 and a concentric annular shoulder in the receiving bore formed by a bore diameter jump between the contact sleeve 11 and the contact carrier 10.
  • the geometric configuration of the pressed elements contact protection pin 1 and contact sleeve 11 ensures that the shank 3 of the contact protection pin 1 is positioned both centrically and perpendicularly and thus aligned with the central axis of the contact carrier 10 and the socket contact 11 .
  • the contact protection pin 1 is centered with the cylindrical outer surface of the shoulder 6 opposite the blind hole.
  • a free cut 12 in the receiving bore prevents double centering, which would otherwise result from the flange 4 resting against the blind bore with its outer cylindrical surface.
  • the shoulder 6 can have a recess 7 on the end face of the contact protection pin 1, so that material is saved on the one hand and the ability of the shoulder 6 to deform elastically in the radial direction is increased on the other hand.
  • the contact protection pin 1 has no device for a tool to pull it out, for example an undercut or a corresponding contact surface, so that the contact protection pin 1 cannot be dismantled without destroying it, since the lamellar bushing 11 is firmly pressed into the receiving bore of the contact carrier 10.
  • the exemplary embodiment shown in Figures 2, 3 and 4 is formed with a contact carrier 10. It is also possible to arrange contact protection pin 1 and socket contact 11 in a receiving bore of a plug contact housing, a connector housing or a housing cover of the plug connection.
