Definitions

  • the invention relates to a connector consisting of two connectors, of which preferably the first is a plug-side connector (plug) and the second connector is preferably called a jack-side connector (socket), according to the preamble of claim 1.
  • plug plug-side connector
  • jack jack-side connector
  • the connector according to the invention is particularly suitable for use in photovoltaic systems.
  • the plug has a contact body with contact pins in the respective socket body or pen body.
  • connectors are regularly under electrical load or under electrical voltage. It is therefore usually difficult and dangerous for a fitter or for persons who typically maintain the system to replace or install such connectors.
  • a special claim on the safety of such connectors is given by a VDE requirement, namely the finger safety, which is checked with the VDE test finger. When touching the connector in the area of the contacts, the VDE test finger must not touch it in an electrically conductive manner. It is therefore necessary to choose a design that meets this requirement.
  • the contact pins with the length L reach to the front end of the plug, they can be touched very easily, if due to the size of the socket with a length Lb and a diameter Db the opening diameter Ds is then so large and the aforementioned VDE Test finger can come into contact with the tip of the contact pin.
  • the contact pin is to have the length Ls of the socket length Lb, contact with the VDE test fingers can only be prevented when the enclosing Plug body or contact body is constructed longer, namely greater than Ls plus the penetration depth of the test finger.
  • the contact pin could also be chosen shorter, so that it lies with its reachable end deep enough in the contact body; but then the effective contact surface would be reduced and this is to avoid it.
  • the invention is therefore based on the task of creating a finger-proof and sealed connector, which on the one hand on site or on site can be assembled, with conventional tools without the use of special tools, while requesting the tightness of the connector, which without much effort in plugged and unplugged state is to be produced.
  • Fig. 1 is a perspective view of a connector 1 according to the invention, formed by the connector 2, 3.
  • the connector 2 is formed as a socket and the connector 3 as a plug. Since the connector 1 consists essentially of two corresponding connectors 2, 3, in the following the connector 2 (socket) is described as an embodiment of the invention.
  • the connector (2) is formed from a housing (4) in which contacts (19) are arranged.
  • the housing (4) is integrally formed from a socket body (6) a housing center body (4a) and a connection body (12), which are formed from any non-conductive insulating material.
  • the socket body (6) has contact openings (8) which extend substantially as cylindrical passages through the entire connector housing (4) therethrough. In the present case two pairs spaced contact openings (8) in the connector (2) are formed, to which from the opposite side each electrical lines can be attached connected.
  • On the housing center body (4a) by means of a connecting element (10) which is integrally connected to the housing (4), a lid (9) attached.
  • the connecting element (10) is formed by means of film hinge (11a) on the housing center body (4).
  • the lid is captively connected to the connector (2).
  • the lid geometry and the receiving geometry of the lid (9) is adapted to the geometry of the socket body (6).
  • the socket body (6) protrudes from the housing middle body (4a) as a plug contour out with a length which is geometrically designed so that the socket contacts therein (19) with the VDE-contact fingers are no longer touchable.
  • the distance between the two domes (21a, 21b) is chosen geometrically such that the VDE test finger can not penetrate as far as the pin contact (20).
  • connection body (12) integrally connects as part of the housing (4).
  • the locking groove (22) is formed as a recess or as a groove in the housing (4).
  • the task of the locking groove (22) is on the one hand the locking of the still to be described Gleit Whylementes (14) and at the same time Dicht.- and Fixiemut or receiving contour for the sealing contour (15) of the Gleit Whylementes (14).
  • connection body (12) there are two screw terminals (13a, 13b), which are arranged accessible from the outside and protrude into the receiving space (23) of the connection body (12).
  • the receiving space (23) is designed so that a conventional stripped cable at its end or a suitably prepared line can be accommodated therein. This can then be connected with conventional screwdriver on the female contact (19) or the connector (3) to the pin contacts (20) accordingly.
  • a sliding, elastic sealing element (14) is used as the sliding sealing element (14), which has cable passages (18a, 18b) through which the cable to be connected passes, as in FIG Fig. 1 and Fig. 2 clearly visible.
  • the cable passages (18a, 18b) are adapted to the line to be connected in accordance with their diameter and seal in consequence of the selection of the material of the Gleitêtlementes (14) radially on the line (24).
  • flat cable can be used by accordingly the cable passages (18a, 18b) to be connected lines (24) or their outer contour are adjusted.
  • the sliding seal element (14) has a sealing space (25), which is formed corresponding to the outer geometry of the connection body (12).
  • the connection body (12) has an approximately cap-like construction in that the two passage openings or cable passages (18a, 18b) are located at the substantially closed end.
  • the elastic sliding sealing element (14) is in a mounting position, which is accomplished by sliding the sliding sealing element against the direction of insertion, as it were, to the rear over the lines (24) to be mounted.
  • the fitter can insert the cables into the recesses (23) of the optional socket contacts (19) or pin contacts (20). Since the sliding sealing element (14) has a sealing contour (15), which is arranged circumferentially at the inner opening end to the sealing space (25), after connecting the lines (24) to the screw connections (13a, 13b), the sliding sealing element can be placed over the outer contour of the Connection body (12) are pushed. When the sealing position is completely reached, the sealing contour (15) slides with its fixing lip (16) into the latching groove (22). It comes insofar to the radial sealing of the aforementioned screw terminals (13a, 13b) and the cable entries and recesses (23) of the connector (2, 3).
  • the sliding sealing element (14) with its sealing space (25) is formed so that a displacement along the connecting body (12) is easily possible.
  • a relatively soft, elastic material for the sealing contour (15) is used, so that this can dive easily with its fixing lip (16) in the locking groove (22).
  • the sealing and insulation is based on the one hand in the area of the plug contour via a likewise attached sealing contour (15) and in the region of the connection body (12) exclusively upper the Gleitêtlement (14) in conjunction with the locking groove (22).
  • a plurality of sealing lips in the region of the sliding sealing element (14) in the sealing space (25) may be arranged, which are spaced in pairs.
  • a second sealing lip in the sealing space (25) could be arranged so that this water inlet between the cable and the cable passages (18a, 18b) which would enter into the gap towards the screw terminals (13a, 13b), keeps away from them ,
  • first sliding sealing element (14) It could also be pushed beyond the first sliding sealing element (14) also a further second sliding seal, designed as a sliding element, so that substantially the entire connector would find space in a second surrounding sliding seal.
