Translation of "Metal bush" in German

According to the invention it is optionally provided that the hollow-cylindrical main body is made as a metal bush insert-molded in a plastics material.

In order to ensure reliable guiding inside the parts made from plastics material in this embodiment it is also advantageous to insert a metal bush into the stepped bore 35 of the rotary actuating knob 26 while an approximately plate-shaped metal insert 37 with a square hole for the external square 25 is inserted in the lower portion of the rotary actuating knob which receives the external square 25 of the journal pin 24 (FIG. 1).

In the vicinity of the entry to the casing 221 of the catalytic converter, a metal bush 259 is inserted into the wall of the exhaust manifold 212 and is welded tightly to a pair of shells of this wall and the inner collection and/or inlet wall 245 .

A metal bush 59, which is made from steel, has a continuous axial hole with an internal screw thread, projects through holes, which are arranged upstream of the catalyst means 41, in the shells 25, 26 and 46 and is tightly welded to these shells.

The invention relates to a round plug connector for screened electric cables, the said connector having an insulating body disposed in a carrier body and a cable screw fitting consisting of a pressing/clamping part and a metal screw bush, wherein the pressing/clamping part presses against the insulating body when the screw bush is screwed onto the carrier body.

Under these circumstances, the bent-over, resilient contact end is shaped in such a way that it comes into contact with a metal screw bush surrounding the plug connector.

This is followed by a metal screw bush 40, with the aid of which the plug connector is held together after the said bush has been screwed onto the carrier housing 3, and also by a shielding bush 45 which, with suitable positioning, passes on the electrical contact from the screw bush 40 to the metal plug part 2 via the insulating carrier body 3 .

According to another feature of the invention, the inserted tongue can have a plastic base section with a wedge-shaped cross section, which longitudinally is divided approximately in half, one side having a forked region with a longitudinal slot forming the leg of the spring clip and the other side having a bore-receiving region equipped with a metal insert bush, which contains the threaded bore.

In principle, the metal insert bush can be fastened in the plastic base section also in other ways, by clamping or by appropriate gluing.

It consists of one plastic base section 1 with an essentially wedge-shaped cross section and of a metal bush 2 inserted therein, which has a threaded bore 3.

The plug connection according to the present invention exhibits a tube shaped plug part 1 and an also tube shaped metal bush 2, which form the plug connection casing.

In addition, the metal bush 2 exhibits on the outside a ring shaped stop collar 7, wherein the stop collar 7 can be furnished about in the region between the end of the receiver part 3 and the beginning of the guide part 4 and wherein the stop collar 7 is furnished with a preferably trough shaped receiver 8 on the side disposed remote to the receiver part 3, wherein a seal not illustrated here can be positioned in the trough shaped receiver 8 .

Advantageously, the metal bush 2 can be spatially fixedly mounted at a wall of a distributor or transmitter casing not illustrated here by inserting the tubular piece 6 from the outside through a hole or, respectively, threaded hole formed in the wall into the casing until the stop collar 7 with the seal comes to rest at the outer face of the casing wall.

The snap in connection assures a safe and nevertheless easily disengageable coupling connection and a comparatively light and nevertheless very reliable plug connection is given, which connection exhibits a high functioning capability even under rough operating conditions and under large impact loads, based on the high impact strength of the metal bush 2 with the integrated stop collar 7 and the metal sleeve 12 as well as with the stable casing jacket 20 and the actuating ring 29, which casing jacket 20 and actuating ring 29 are made out of an impact resistant plastic.

The high safety against outer impact loads is in particular also reached or, respectively, favored by having the outer diameter of the bearing part 15 substantially free of play supported in the inner diameter of the receiver part 3 of the metal bush 2 with a fitting.

For this purpose, a sleeve 10b is shaped into seat shell 10 which itself is lined by a metal bush 25.

To minimise the transfer of heat between the cap nut 6 and the bearing bush 20 screwed onto the outer conductor of the coaxial line in a plug-connector part of this kind, a synthetic-material ring 30 is placed onto the metal bearing bush, thereby thermally decoupling the bearing bush 20 from the metal bearing cover 23 screwed into the cap nut 6 .

Additionally, a synthetic-material ring 31 is inserted into a corresponding groove on the outer circumference of the annular flange 26 of the metal bearing bush, so that this flange 26 is also thermally decoupled from the externally surrounding internal wall of the cap nut 6 .

For this purpose a collar 28 is formed on at the opening of the protective cap 26. The collar 28 has a hexagon receptacle 29 at theinside in which the metal bush 27 is axially guided and secured with respect to rotation by a hexagonal outer contour.

To prevent the metal bush 27 from falling out of the hexagon receptacle 29 of the protective cap 26, three radially directed projections 30 which are uniformly distributed along the circumference are formed on at the protective cap 26at the front end of the hexagon receptacle 29 and an additional three radially inwardly directed projections 31 are provided in the rear area ofthe hexagon receptacle 29.
