Definitions

  • the invention relates to the assembly of a multi-core, in particular two-core, sheathed cable to an electrical plug and an electrical plug with a sheathed cable connected to it.
  • the second embodiment of the EP 0696827 A2 discloses the preamble of claim 4.
  • the invention is based on the object of enabling the simplest possible assembly of a plug with a sheathed cable connected therein and at the same time ensuring a good sealing effect.
  • the invention is further solved by an electrical plug with a multi-core sheathed cable connected to it according to claim 4.
  • the plug is arranged on a multi-core sheathed cable which extends in a longitudinal direction and has a plurality of cores surrounded by a cable sheath.
  • the procedure is such that the sealing element made of a sealing material is first applied to the wires, in particular pushed on.
  • the sealing element has an individual feedthrough for each wire through the sealing element.
  • the sheathed cable prepared in this way with the arranged sealing element is then inserted from behind into a plug housing of the plug and mounted therein.
  • the sealing element is inserted into a rear receptacle of the plug housing until the sealing element lies in the receptacle in a particularly sealing manner.
  • the sealing element is preferably moved along the wires into the receptacle.
  • a sealing jacket is then attached, which extends from the rear end of the connector housing to the cable jacket.
  • the sealing element is a one-piece, i.e. monolithic part, which lies sealingly in the receptacle of the plug housing. Because the sealing element is made in one piece, the sealing element can be manufactured easily and cost-effectively. Furthermore, due to the one-piece nature of the sealing element, a better sealing effect is achieved than, for example, in comparison to a multi-part sealing element.
  • the sealing element is first applied to the plurality of wires and then - then after attaching the sealing element - a contact element is attached to the end of each wire, for example crimped.
  • the contact elements are used to mount the wires in the plug housing of the plug.
  • automated methods are preferably used, through which advantages with regard to the assembly process are achieved. Assembly can be done easier and faster.
  • the casing is preferably applied in particular by a casting or spraying process.
  • a casting or spraying process for example, known casting or spraying processes are used, which further simplify and accelerate the assembly process.
  • the sealing behavior of the sealing element can be influenced by the injection force. This means that the greater the press-in force, the stronger the sealing element is pressed into the receptacle and the better the sealing behavior. Sealing behavior is understood to mean a sealing effect of the sealing element, for example longitudinal watertightness.
  • the sealing element is expediently designed in the manner of a cone element, i.e. it tapers in the longitudinal direction.
  • the injection process and the associated press-in force improve the sealing effect between the sealing element and the wall of the receptacle on the one hand and between the sealing element and the individual wires on the other hand, so that a reliable seal is guaranteed.
  • the cone shape creates a simple geometry of the sealing element, which enables simple production.
  • the sealing element generally has a circumferential lateral surface on, whereby this encloses an acute angle to the longitudinal direction. This is, for example, in the range of 5° - 35° and preferably in the range of 10° - 20°.
  • the entire lateral surface of the sealing element is preferably smooth and in particular designed without circumferential ribs or grooves.
  • the sealing element is generally a prefabricated one-piece component which - apart from the bushings for the individual wires - has no further openings or slots or the like.
  • the sealing element is also made of a softer material than the plug housing. In other words, the sealing element has a lower hardness than the plug housing.
  • the sealing element has a thermoplastic polyurethane material (TPU material). This has the advantage that the sealing element fits into the plug housing in a form-fitting manner due to the press-in force and thus increases the sealing effect.
  • the sealing element By designing the sealing element as a one-piece component, a significantly simplified assembly is achieved in particular. No complicated handling of two half-shells is required. Rather, it is possible to simply slide the sealing element onto the wires. This is conveniently done automatically. The displacement of the sealing element along the wires into the receptacle is also preferably carried out automatically, for example with the help of an auxiliary tool.
  • the sealing effect of the sealing element on the one hand to the wall of the receptacle of the plug housing and on the other hand to the individual wires is preferably further influenced and adjusted by the choice of injection pressure during injection molding.
  • the sheathed cable is preferably a two-core sheathed cable with two cores.
  • Fig. 1 a perspective exploded view of a pre-assembled plug 2 is shown, which is assembled onto a sheathed cable 4.
  • the sheathed cable 4 is designed as a two-core sheathed cable with two wires 10 which are surrounded by a cable sheath 12.
  • the wires 10 are each stripped of insulation at their front end (i.e. the end with which they are arranged in the plug 2).
  • a contact element 14 is attached to the stripped point of the wires 10.
  • a sealing element 16, which consists of a soft, elastic plastic material, in particular TPU, is pushed onto the two wires 10.
  • the sealing element 16 is designed as a cone element, i.e. has a lateral surface 18 which tapers with respect to a longitudinal direction 20 at an acute angle to this longitudinal direction 20. In order to push the sealing element 16 onto the wires 10, the sealing element 16 has an individual feedthrough 17 for the wires 10.
  • the sealing element 16 has an at least approximately oval base area.
  • the base area has two opposite rectilinear sections, each connected to one another via a (circular) arc are.
  • the base area can also be circular.
  • the lateral surface 18 is therefore designed in particular in the manner of a conical lateral surface.
  • the plug 2 has a plug housing 6.
  • the plug housing 6 is preferably a plastic housing and has a receptacle 22 on its rear end facing the sheathed cable 4, which is designed to receive the sealing element 16.
  • this receptacle 22 also has a conical design complementary to the sealing element 16.
  • the plug housing 6 has webs 24 or ribs on its outer wall 21 in the area of the receptacle 22.
  • the webs 24 are designed all around, with a central web 24 being interrupted in the exemplary embodiment.
  • the webs 24 create a positive connection with a casing 8 (cf. Fig. 3 ) is formed, which is effective in and against the longitudinal direction 20.
  • the interruption of the middle web 24 also creates a positive connection that is effective in the circumferential direction.
  • the webs 24 are delimited by a circumferential collar 26.
  • a sprayed or cast-on sheath 8 is applied, which extends to the cable jacket 12 of the sheathed cable and thus ensures a reliable and secure seal.
  • Fig. 2 the plug 2 is shown in an assembled state.
  • the wires 10 provided with the contact elements 14 were inserted into the plug housing 6.
  • the sealing element 16 pushed onto the wires 10 is arranged in the receptacle 22 of the plug housing 6, preferably in a form-fitting manner.
  • Fig. 3 the finished plug 2 is shown with the attached sheathed cable 4.
  • the plug 2 has the plug housing 6 and a sprayed-on casing 8, which encloses the area into which the sheathed cable 4 is inserted into the plug housing 6.
  • the casing 8 extends to the collar 26 and lies against the front side of it. It is poured or sprayed on and is solid. Due to the pressure generated during application, the sealing element 16 is pressed into the receptacle 22 in the longitudinal direction 20, so that the sealing effect is improved.
