Definitions

  • the present invention relates to a connecting device according to the
  • a connecting device according to the preamble of claim 1 is known from the older, not previously published German patent application DE 10 2012 205 932.6.
  • This Verbtndungs consists essentially of two elements, namely a clip element and a fuse element,
  • the object of the invention is to provide an improved connecting device, which is particularly suitable for mass production, as well as to provide a method for the production of such a connecting device.
  • the starting point of the invention is a connecting device with a clip element, which has a section that is elastic in a radial direction and that can be clipped onto a male control element with elastic widening.
  • the connecting device further comprises a securing element, which in a Aufschiebecardi on the clip element is pushed, especially if the clip element on a male
  • the Fuser is clipped.
  • the securing element has a sleeve-like portion, which abuts in a pushed onto the clip element state from the outside to the elastic portion of the clip member.
  • the sleeve-like portion has the task of complicating or preventing that the clip element can expand in the radial direction, i. that it can be inadvertently removed from the male fixing element. When removed from the Cüpelement or deducted fuse element but the clip element can very well be deducted again from the male fixing.
  • the essence of the invention is that the clip element and the securing element are injection-molded from a plastic material or plastic materials differing from one another.
  • the clip element and the securing element are therefore injection-molded parts.
  • a lower end of the securing element is integrally connected to an upper end of the clip element by way of a separable connecting web which can be separated or torn off during assembly of the connecting device.
  • the clip element and the securing element are captively connected to one another via the tear-off during assembly connecting web, which is particularly for large-scale production of advantage.
  • an injection molding tool or an injection molding tool is first provided, which has a first cavity complementary to the shape of the clip element and a second cavity that is complementary to the shape of the securing element.
  • the two Kav 'rt2011en are arranged to one another such that a lower end of the fuse element to be sprayed to be sprayed to an upper end of the Clipelement facing or overlapped with this.
  • the two cavities are connected to each other via a connecting cavity.
  • the injection molding tool further has a first channel, via which the first cavity is filled with a plastic material. Accordingly, the second cavity has a second channel, via which it is filled with Kunststoffmatertal.
  • the filling of the two cavities is controlled so that the two cavities are completely filled at about the same time, with the result that plastic material from the two cavities enters the connecting cavity at about the same time.
  • the plastic material penetrating from each of the two cavities into the connecting cavity has already cooled down at least somewhat during the spraying process, with the result that the connecting web connecting the clip element and the securing element forms a "naturally weak point", which during assembly of the connecting device by hand can be torn off or torn apart.
  • the connecting web has in the unassembled state of the connecting device the function of a captive, which ensures that the clip element and the fuse element remain connected to each other.
  • first cavity in a first tool part of the injection molding tool and the second cavity in a second tool part of the injection molding tool is injected.
  • the connecting cavity can be provided in the region of the parting plane of the two tool parts of the injection molding tool.
  • Figure 4 shows an alternative embodiment of a connecting device according to the invention
  • FIG. 5 further embodiments of a connecting device according to the invention.
  • FIG. 7 shows an injection molding tool for producing a connecting device according to the invention.
  • FIG. 1 shows a first sheet-metal component 1 onto which a ball 2, which acts as a male fixing element, is welded on.
  • the sheet metal component 1 is intended to be connected to a second sheet metal component 3.
  • the second sheet metal construction 3 has a through hole 4.
  • a connecting device is provided, which is formed by a clip element 5 and a securing element 6 cooperating therewith.
  • the clip member 5 has a lower, radially-elastic portion 5a and an upper, substantially inelastic portion 5b.
  • a substantially complementary to the ball 2 designed spherical recess 5c is provided in the lower portion 5a substantially complementary to the ball 2 designed spherical recess 5c is provided.
  • the upper inelastic portion 5b has a circumferential recess 5d, resulting in a circumferential protruding edge 5e.
  • the securing element 6 has a sleeve-like lower portion 6a, the inner diameter of which essentially corresponds to the outer diameter of the elastic portion 5a of the clip element 5.
  • Upwardly upstanding from the sleeve-like portion 6a are spring-like elements 6b, 6c.
  • Radially outwardly from the sleeve-like portion 6a is a mushroom or hat-like Andrückrand 6d, which is in a Aufschiebecardi 7 or opposite to bending elastic.
  • the clip element is first brushed onto the ball 2, which is shown in FIG. Before or after clipping the clip element 5 onto the ball 2, the second component 3 is placed on the first component 1. Subsequently, the securing element 6 is pushed in Aufschiebecardi 7 on the clip element until, as can be seen from Figure 3, the spring-like elements 6b, 6c are engaged in the recess 5d of the clip element. The pressing edge 6d engages over the hole 4 provided in the second component 3 and presses the second component 3 against the first component 1. The spring-like elements 6b, 6c prevent an automatic or unintentional removal of the securing element 6 from the clip element 5.
  • the sleeve-like section 6a of the sealing element is essentially inelastic, in particular in the radial direction. A radial widening of the elastic portion 5a of the clip element and thus an automatic release of the second component 3 from the first component 1 is thus excluded as long as the securing element 6 is pushed onto the clip element 5.
  • FIG 4 shows an embodiment in which on the inside of the recess 5c, a corrosion-inhibiting material 8a is applied.
  • the corrosion-inhibiting materials 8a, 8b may be an expandable material, ie, a material that is exposed to heat (eg, during painting or spraying) Drying process) swells and possibly between the clip element 5 and / or the securing element 6 and / or the components 1, 3 remaining cavities closes or seals, which significantly reduces the risk of corrosion in these areas.
  • Figure 5 shows an embodiment in which in addition to the provided on the securing element 6 spring-like elements 6b, 6c on the clip element 5 spring-like elements 6b ' , 6c ' are provided, which engage with the spring-like elements 6b, 6c.
  • FIG. 6 shows an exemplary embodiment in which, in addition to the spring-like elements 6b, 6c provided on the securing element 6, spring-like elements 6b ', 6c' are also provided on the clip element, which engage with the spring-like elements 6b, 6c, in which case the pressure edge 6d is provided above the spring-like element 6c ' .
  • FIG. 7 shows an injection tool 10, consisting of an upper tool 10a and a lower tool 10b.
  • Kavrt2011 1 1a is provided in the upper tool 10a .
  • Kavtt2011 1 1a is provided in the lower tool 10b a complementary to the clip element 5 second Kavtt2011 1 1b is provided in the lower tool 10b .
  • the two cavitites 1a, 11b are arranged so that a lower end of the fuse element 6 to be sprayed faces an upper end of the clip element 5 to be sprayed.
  • the two Kavititen 11 a, 11 b are connected via a connection kungsktician 12 together.
  • Plastic material can be introduced into the first cavity 11a via a first sprue 13a provided in the upper tool 10a. About one Plastic material can be introduced into the second cavity 11 b provided in the lower die 10 b in the lower die 10 b.
  • the filling of the two cavities 11a, 11b is controlled with plastic material so that the two cavities 11a, 1b are completely filled at about the same time and plastic material approximately simultaneously from the two cavities 11 a, 1 1 b in the Connecting cavity 12 occurs.
  • the connecting device If the connecting device is to be mounted, then first the clip element 5 can be clipped onto a male fixing element (not shown). If the securing element 6 is pressed further “downwards", the connecting web between the clip element 5 and the securing element 5 ruptures when a predetermined force is exceeded, so that the securing element 6 can be pushed onto the clip element 5 from the outside.
  • the clip element 5 can be injection-molded from the same plastic material as the securing element 6.
  • the two elements 5, 6 can also be injection-molded from different plastic materials.
