When the insertion member is fired and moved in the insertion direction, the elastic section rubs against the surrounding member as the insertion member moves.

This card guide is interrupted for a section, downwards and in the direction of insertion (3).

The inlet surface (31) contains a grooved structure (R), at least in sections, which is oriented in such a manner that it has a direction component in the direction of introduction (E).

When seen in the direction of insertion of said contact, the block seal is divided into at least two insertion areas in the region of each respective electric contact.

An essential feature value class is computed, and the insertion direction corresponding to the feature value is computed.

Formed at the rear end, in the plug-in direction (E), of the outer contour (17), is a circumferential stop (20, 21).

The at least one snap connection (5) holds the headlight (1) between two bearing surfaces (9, 10) in and counter to the direction of insertion (8) without any slack.

The guide groove (4) can be tapered in the direction of advancement of the circuit board (5) in a continuous or partial manner.

The actual position of the tool (19), particularly in the direction of the longitudinal axis of the tool (19) or in the direction of insertion, is determined before and/or during the insertion of the tool (19) into the clamping chuck (18).

The feed mechanism (5) comprises a threaded rod (15) with a rotational axis (20) in the insertion direction (25) of the storage medium (10).

Said tie bolt comprises fixing means (4) and an anchoring section (5) having a cross-sectional enlargement (6) in the direction of insertion.

The clip (1) has a holding mouth (11) and a socket mouth (12) inside which notches are formed at required intervals in the insertion/removal direction.

The variable intake passage (16) has a cross section that gradually increases from an upstream side to a downstream side in the air introducing direction.

For both plug-in connections (3,4), the individual bearing surfaces (9,10) of the snap connection are the only surfaces which are used to hold the headlight (1) in and counter to the direction of insertion (8).

The wall (4) of said polygonal recess (3) is provided with a window (5) in which a pressure piece (6) is disposed that can be displaced in the direction of insertion (E).
