- a cable 16 emerges centrally from the linkage 11 and in a central bore in the rod connection 15 a. Via an outlet opening 18 in the wall of the linkage connection 15 is the cable 16 from the drive adapter 10 led out.
- the outlet opening 18 is with a sealing screw 19 against the escape of drilling fluid sealed.
- the cable 16 is from the sealing screw 19 led to a slip ring terminal 20.
- the slip ring terminal 20 is in direct contact with the slip ring 14 and rotates with this the rod axis.
- the slip ring 14 is axially displaceable or adjustable stored on the rod connection 15 and in his Width dimensioned so that the contact with the pantograph 12 even with an axial displacement of the slip ring persists.
- the linkage adapter 100 has in the region of the linkage connection 103 a rod socket 104 with electrical Plugs 105.
- the plug 105 connect within the Rod sections 101,102 running on its axis electrical lines 106, 107 (coaxial cable). Furthermore
- the rod sections have 101,102 different Channels 108, 109 (annular gap for conduction medium) for various Media.
- the electrical connector 105 is against the e.g. Channels 108, 109 containing liquid media sealed. The media can also be transferred use of impulses.
- the electrical connector consists of a Plug 111 and a box 112, which when connecting Sliding into each other and thus a safe make electrical contact.
- This connection can be designed as a swirl coupling.
- the electrical connectors are through a seal 113th and a seal 114 sealed against its environment.
- the connectors or cables are with cable locks 115,116 fixed so that the flow of media in the channels 108,109 is not hindered.
- the additional Ring channel 109 allows the separate transport of two different media.
- the linkage member preferably has on one side an outer and on the other side preferably one Inner thread. So a drill string can consist of several Be composed of single rods.
- a measuring device arranged in the region of the drill head can Therefore, for example, when the drill head a specific Has traveled and whose position is determined is to be connected to a power source by the rod protruding from the bore (Fig. 1, Item 11) to the machine or data recycling unit or power source is connected.
- the consumer adapter is in the housing 205 of a drill (not shown) a transmitter 215 in a cylindrical Chamber 210 arranged.
- the transmitter 215 has cylindrical housing, whose outer diameter is less than the inner diameter of the chamber 210. With the help of slip rings 220, the transmitter 215 is in the chamber 210 stored that it is axially displaceable.
- the axial movement of the transmitter 215 within the cylindrical Chamber 210 is in a damper mount 225th arranged damper 230 buffered, which is connected to a metallic Plugs 235 abut.
- the Connection consists of a ground spring 296, which is supported on the metallic plug 235 and is slidably mounted.
