- 11 shows an assembly 1 (also referred to as a header core) with a first receiving device 2 for an electrode plug and a second receiving device 13 for a further electrode plug.
- the first receiving device 2 has a front opening 6 through which the electrode plug can be inserted.
- the first receiving device 2 has a first section 3, a second section 4 and a third section 5.
- the diameter of the first section 3 is larger than the diameter of the second section 4.
- the diameter of the second section 4 is again larger than the diameter of the third section 5.
- the first receiving device 2 is from the front opening 6 towards the end gradually tapered.
- a first connection element is formed between the first section 3 and the second section 4 (that is to say in a front region of the first receiving device 2).
- a second connection element 8 is formed between the second section 4 and the third section 5 (in a rear region of the first receiving device 2).
- Both the first connection element 7 and the second connection element 8 have at least two flat side surfaces. This enables the assembly 1 to be gripped easily during assembly and enables the assembly steps to be automated.
- the first connection element 7 and the second connection element 8 are essentially cuboid.
- the second connection element 8 has a bevelled edge 17, which serves to save material and to take into account the flow direction of the epoxy resin.
- On a back of the first Connection element 7, a recess 12a is formed in the plastic coating.
- a rear opening 12b is formed on a rear side of the second connection element 8.
- the assembly is partially surrounded by a plastic 11.
- the assembly is partially extrusion-coated with polysulfone.
- Recesses for a first contact surface 9 and a second contact surface 10 are formed in the plastic 11.
- the first and second contact areas are formed as circular areas.
- a guide 16 is formed adjacent to the first and second contact surfaces 9, 10.
- the guide 16 serves to receive a connection element (e.g. a wiring tape).
- the guides on the contact surfaces prevent connection elements from different contact surfaces from touching each other.
- the second receiving device 13 is constructed analogously to the first receiving device 2. For reasons of clarity, the components of the second receiving device (an opening, the three tapering sections and the two connecting elements) are not provided with reference numerals.
- the second receiving device also has two contact surfaces (third contact surface 14 and fourth contact surface 15) for connections. Guides are again formed adjacent to the contact surfaces.
- a positioning device 18b is formed, which is designed as a pin with a tapered end.
- the pointed end of the positioning device 18b can be inserted into a receptacle of the housing in order to facilitate the fitting of the assembly on the housing.
- the assembly can also be designed without a positioning device 18b.
- Positioning pins 18a are formed on an underside of the assembly (see FIG. 12).
- the positioning pins can be arranged in associated receptacles when the assembly is arranged on the housing of the implant. In the embodiment shown, two positioning pins are shown, however other numbers of positioning pins are possible.
- the first receptacle 2 and the second receptacle 13 each have a spring sleeve and a plug receptacle.
- the first receptacle 2 and the second receptacle 13 can be designed as IS-1 connectors.
- a spring element 20 is arranged in the first receiving device 2 and fastened there (left side of FIG. 13).
- the recess 12a in the plastic is used to weld the spring element 20 arranged in the interior of the first receiving device 2 into the first connection element 7 by means of resistance welding.
- a further spring element is arranged and fastened in the second receiving device 13 (not shown).
- the openings of the assembly 1 are then closed and sealed with potting aids 21, 22, 23 (right side of FIG. 13).
- FIG. 14 A further assembly step is shown in FIG. 14.
- a wire tape 24 is attached (e.g. welded) to the third contact surface 14.
- the wire band 24 has a wire band connection 25 which can be connected to a pin contact of a bushing 30 (cf. FIG. 4) and can be plugged onto the pin contact, for example. Further wire strips are connected to the other contact surfaces 9, 10, 15.
- An antenna 26 is attached to the assembly 1.
- the antenna 26 partially encompasses the first section 3 of the first receiving device 2 and is clipped onto it.
- the antenna 26 has a U-shaped section 27. This forms a recessed grip that can be used, for example, with an automated gripper to hold and transport the assembly.
- an antenna connector 28 is formed for connection to the feedthrough 30.
- the assembly with the wire straps and the antenna is then arranged in a casting mold (e.g. a silicone mold) (not shown).
- the wire band connections and the antenna connection 28 are plugged into assigned pins of the feedthrough 30 and connected to the pins (for example welded).
- the mold will sealed and filled with a synthetic resin 31 (e.g. epoxy resin).
- the electrode connection device is molded (cf. FIG. 16).
- the potting aids 21, 22, 23 are removed and, if necessary, excess resin is removed from the outer surfaces, e.g. B. by grinding and / or polishing.
- the implant with the electrode connection device is now fully assembled (Fig. 17).
- the electrode connection device 53 is attached to a cover 121.
- the energy store 62 is accommodated in a housing 120.
- the housing 120 can be provided as a deep-drawn shape.
- the cover 121 is welded to the housing 120 along a circumferential weld 122 to close the housing 120.
- a support frame 69 is arranged on the energy store.
- the support frame 69 receives the electronics module.
- the electrode connection device 53 can be formed, for example, according to the embodiment shown in FIGS. 11 to 17.
- the bushing 65 with the pins 70 is welded into the cover 121.
- the internal structure of the electronic implant is significantly simplified, so that manufacturing costs are reduced.
- the number and complexity of the manufacturing processes required also decrease, so that the scalability of manufacturing is favored (e.g. the simplified transfer to other locations, less training requirements for employees, lower requirements for the required manufacturing environment and accompanying engineering).
- Reworking is also possible or simplified if releasable connection techniques are used.
- the implant With the form factor of the electronic module, the implant can be reduced in size or the volume obtained can be used to increase the battery capacity and thus to extend the life of the implant.
- the manufacture of the electronic module in uBGA technology enables an increase in the benefits on the Panel and the associated savings in production costs.
- the vertical mounting of the electronics module (parallel to the front of the energy storage device) enables electrical connections without angles and thus a simpler, cheaper construction of the implant optimized for automatic production in one axis.
