Definitions

  • Plugs of the type in question are also referred to in particular as built-in plugs, i.e. the plugs are not attached to the ends of electrical lines or cables, but rather are firmly installed in an electrical device, in particular in the housing of an electrical device.
  • Plugs of the type in question here represent in particular the male part of the electrical connector that they form with the complementary coupling.
  • the coupling forms in particular the female part of the electrical connector.
  • a contact protection element can be designed such that it extends finger-like against the first direction.
  • the contact protection element preferably protrudes, at least essentially, parallel to the contacting areas of the contact elements into the receiving space.
  • These finger-like contact protection elements preferably extend further into the receiving space against the first direction than the contacting areas of the contact elements.
  • a plurality of contact protection elements can form a barrier of individual, in particular at least essentially punctiform, barriers for an penetrating body part.
  • the at least one touch protection element or at least one further touch protection element is part of the receiving element. This means in particular that the corresponding contact protection element with the receiving element is inserted into the housing when the electrical plug is assembled. As a result, the contact protection elements do not take up any space inside the housing until the receiving element is inserted into the housing. therefore do not represent an obstacle, especially when it comes to assembly work.
  • the contact protection elements in one piece with the receiving element, for example as a one-piece injection molded part and / or plastic part.
  • the receiving element can, for example, have a wall pointing toward the contact carrier element, on which at least one contact protection element is received or with which at least one contact protection element is formed in one piece.
  • This wall can expediently have openings through which the contacting areas of the contact elements can enter the receiving space.
  • the contact protection elements can also be formed as a component of the contact carrier element and / or in one piece with the contact carrier element.
  • Such a design offers the particular advantage that when the receiving element is installed in the housing, its position relative to the housing and contact carrier element can be determined along the first direction relative to the housing. This can be done, for example, by means of a stop which prevents further insertion of the receiving element into the housing beyond a certain position along the first direction. Any tolerances in the relative position of the contact carrier element and housing along the first direction to one another can be compensated for by the design of the plug with the plug-in section and plug-on section. Depending on the position of the actual relative position in the tolerance field, it is possible, for example, that the plug-in section penetrates further or less far into the plug-on section.
  • the first sealing element or the second sealing element can be an O-ring.
  • This can consist in particular of a rubber-elastic material.
  • This can in particular consist of consist of a rubber-elastic material.
  • Such O-rings have the advantage that they are available as standard parts and can therefore be used inexpensively. Surprisingly, it has been shown that a simple seal can also be achieved with simple O-rings if the sealing function, as described above, is divided between the two sealing elements.
  • the contact carrier element and / or the receiving element in particular the push-on section and / or the push-in section, can have a groove for receiving the second sealing element.
  • a groove can prevent slipping in or on the respective component.
  • the groove can in particular run at right angles to the first direction. In such a case, the groove ensures that the second sealing element remains in its intended position relative to the receiving element and / or contact carrier element when the two elements are brought into engagement with one another.
  • the electrical device can be a converter and / or an inverter.
  • it can be a converter and / or inverter for use in a motor vehicle.
  • FIG. 1 shows an exemplary connector with a suitable coupling in a perspective view
  • FIG. 5 shows a perspective illustration of an alternative receiving element
  • the connector shown as an example can have a first sealing element 34 and a second sealing element 36.
  • the first sealing element 34 is arranged between the housing 18 and the receiving element 14. As in the example shown, it can be squeezed there along the first direction 28.
  • a first sealing element 34 designed as an O-ring as shown in FIG. 5, can also be arranged in the region of the contact surface 38, as shown in FIG. 5, so that it can be pressed onto the housing 18 by this.
  • a circumferential groove is particularly advantageously provided, in which the first sealing element 34 configured as an O-ring is arranged.
  • FIGS. 6 to 9 An exemplary connector is shown in FIGS. 6 to 9, the illustration only showing the contact elements 10, contact carrier element 12 and receiving element 14 in an exempted illustration.
  • the exemption makes the at least one touch protection element visible in particular.
  • the receiving element 14 can have touch protection elements 46 which extend finger-like into the receiving space against the first direction 28.
  • the touch protection elements 46 form individual, essentially punctiform obstacles against the penetration of a body part.
  • a point-shaped obstacle is not only to be understood as a dimensionless point in the mathematical sense, but rather an obstacle that acts as an obstacle - quasi punctually - only in a small spatial part of the recording space.

Abstract

L'invention concerne un connecteur électrique destiné à former une connexion électrique enfichable avec un accouplement (16) complémentaire du connecteur, comportant une pluralité d'éléments de contact métalliques (10) destinés à établir un contact électrique avec un dispositif électrique disposé dans un boîtier (18), un élément de support de contact (12) et un élément de réception (14) destinés à recevoir l'accouplement (16) dans un espace de réception entouré par l'élément de réception (14). L'élément de réception (14) peut être inséré dans le boîtier (18) par une ouverture dans le boîtier (18) selon une première direction (30). L'élément de réception (14) pour former le connecteur peut être mis en prise avec l'élément de support de contact (12) le long de la première direction (30), les éléments de contact (10) étant passés à travers l'élément de support de contact (12) et présentant des zones de contact (30) qui, lorsque l'élément de réception (14) est mis en prise avec l'élément de support de contact (12), s'étendent à l'opposé de la première direction (30) en s'éloignant de l'élément de support de contact (12) dans l'espace de réception. Le connecteur comporte au moins un élément de protection contre les contacts (46, 48) qui, lorsque l'élément de réception (14) est mis en prise avec l'élément de support de contact (12), est disposé dans l'espace de réception et est conçu pour empêcher qu'une partie du corps humain, en particulier un doigt, qui pénètre dans l'espace de réception, ne touche les zones de contact.
