- the contact elements 108 are designed as crimp contacts. These contact elements 108 include a crimpable contact portion 110 and an elastically pluggable
- the crimped crimping portion 110 has a different material from the elastically pluggable portion 112 and may be formed of a different material thickness than the elastically pluggable portion 112.
- the vibration-proof mechanical fuse is formed as a pair of locking clips 114 attached to opposite lateral end portions of the housing 104.
- the locking clips 114 are manually operable by a user by means of a corresponding pair of grips 116 in an upper end portion of the housing 104.
- the locking clips 114 are adapted to engage in correspondingly formed locking receiving openings 116 of the printed circuit board 28.
- FIG. 22 shows the connector assembly 100 in a mated condition
- Fig. 23 shows the connector assembly 100 in a disconnected condition shows.
- FIG. 24 shows the connection arrangement 100 in a cross-sectional view. In this is shown how the elastically pluggable portions 112 are resiliently received by the corresponding holes 54, at the same time a reliable electrical contact is made.
- connection arrangement 100 With the connection arrangement 100 according to FIGS. 22 to 24, a direct insertion using latching clips 114 is thus made possible.
- the plug element 102 is inserted into the circuit board 28 and locked there by means of the latching clip 114.
- a tolerance compensation of the blanket can be done via a deep milling on the underside of the board or circuit board 28.
- connection assembly 130 according to another exemplary embodiment will be described
- Embodiment of the invention in a first operating state (Fig. 25) described, in which a plug-in element 132 is inserted into a printed circuit board 28, and described with reference to FIG. 26 in a state in which the plug-in element 132 is not inserted into the circuit board 28.
- a vibration proof mechanical fuse is formed as a pair of screw members 134 disposed on laterally opposite lower end portions of the housing 104 and adapted to engage with a respective corresponding threaded bushing 136 of the printed circuit board 28.
- a threaded bushing 136 is pressed into the printed circuit board 28 at two points, which has an internal thread, which corresponds to an external thread of the respective screw member 134.
- the threaded bushes 136 may also be bolted to the board or printed circuit board 28 or alternatively be pressed. Thickness tolerances of the board or printed circuit board 28 can be compensated by a screw-in depth.
- FIGS. 27 to 29 show different views of a connection arrangement 150 according to yet another exemplary embodiment of the invention, in which again a
- Vibration robustness and optionally a high current capability is enabled.
- FIG. 27 shows a plug-in element 152 in a printed circuit board 28 in the inserted state, whereas according to FIG. 28 the plug-in element 152 is shown in a non-plugged state with respect to the printed circuit board 28.
- FIG. 29 shows a partial cross section through the connection arrangement 150, by means of which the resiliently elastic receiving characteristic of the electrically pluggable sections 112 of the plug element 152 can be recognized.
- the vibration-resistant mechanical fuse is realized using a pair of expansion rivets 154, 154 'that can be actuated by actuators 138 and inserted into correspondingly provided rivet receiving openings 156 in the circuit board 28.
- the direct insertion is realized by means of expansion rivets 154, 154 ', whereby the respective rivet bolts can be pressed in and variably spread. Tolerances of the board thickness, that is, the thickness of the circuit board 28 can be compensated.
- Fig. 28 shows a active expansion rivet 154 and an inactive expansion rivet 154 ⁇ In the interior of the housing 104, the associated expansion rivet bolts are arranged.
- FIGS. 30 to 32 show a detailed view of the contact elements 108 configured as crimp contacts.
- FIG. 30 shows that the crimpable crimping portion 110 and the elastically pluggable portion 112 are realized with each other mechanically and electrically using a combined embossing and riveting joint 170.
- a fork contact for holes with a diameter of 2.3 mm to 2.5 mm is provided.
- Wieland K55 or Wieland K88 with a material thickness of 0.8 mm can be used as material for the elastically pluggable section 112.
- the crimpable crimping portion 110 includes a crimping zone 172 for a cable receptacle having a cross-sectional area between 1.5 mm 2 and 2.5 mm 2 .
- bronze CuSn 6 having a material thickness of 0.4 mm can be used.
- FIG. 30 shows that the sections 110, 112 overlap in an overlapping region 176 and are connected to one another there by means of the embossing and riveting connection 170.
- FIG. 31 shows another spatial view and FIG. 32 shows a side view of the contact element 108.
- “having” does not exclude other elements or steps and "a” or “an” does not exclude a multitude.
