## Abstract

A mounting method for a circuit board. The circuit board is formed with pilot holes that are placed onto pilot pins of a tool such that the pilot pins protrude through and beyond the circuit board. Then the tool is displaced toward a circuit board holder of the housing whereupon the pilot pins engage with a form fit in corresponding centering holes of the circuit board holder. After fixing the circuit board in the housing, the tool is withdrawn by detaching the pilot pins from the pilot holes, the circuit board remaining in the circuit board holder. The tool has an upper plate with associated pilot pins and a lower plate with a housing holder for positioning the housing. The circuit board, with the pilot pins engaging the pilot holes, is displaced by moving the upper plate toward the lower plate.

## Claims

### Claim 1

A method of mounting a circuit board in a housing, the method which comprises:
providing a circuit board with at least one pilot hole and placing the circuit board onto a mounting tool having a number of pilot pins, wherein each of the number of pilot pins protrudes through and projects beyond the circuit board on a side facing away from the mounting tool;
displacing the mounting tool toward a circuit board holder of the housing to cause the pilot pins or at least one of the pilot pins to engage in a corresponding centering hole of the circuit board holder;
fixing the circuit board in the housing; and
withdrawing the mounting tool by detaching each pilot pin from the corresponding pilot hole, with the circuit board remaining in the circuit board holder.

### Claim 2 (depends on 1)

The mounting method according to claim 1, wherein said at least one pilot hole is one of a plurality of pilot holes formed in the circuit board and the mounting tool is provided with a plurality of pilot pins disposed at locations corresponding to locations of the pilot hoes of the circuit board.

### Claim 3 (depends on 1)

The mounting method according to claim 1, which comprises, during an introduction of the circuit board into the circuit board holder, closing a press-contact connection by causing a press-contact pin of an electrical terminal conductor disposed in the housing to penetrate into a corresponding contact hole of the circuit board, and thereby forming a force closure.

### Claim 4 (depends on 3)

The mounting method according to claim 3, which comprises fixing the circuit board in the housing exclusively by the press-contact connection.

### Claim 5 (depends on 3)

The mounting method according to claim 3, which comprises fixing the circuit board in the housing primarily by the press-contact connection.

### Claim 6 (depends on 1)

The mounting method according to claim 1, wherein, when the circuit board is placed onto the mounting tool, the or each pilot pin forms with the circuit board a connection holding the circuit board on the mounting tool counter to a weight thereof.

### Claim 7 (depends on 6)

The mounting method according to claim 6, wherein the connection between the mounting tool and the circuit board is a friction closure or a form fit connection.

### Claim 8 (depends on 6)

The mounting method according to claim 6, which comprises, during or after the insertion of the circuit board into the housing, forcibly releasing the connection between each pilot pin and the circuit board by moving a detaching mechanism relative to the pilot pin.
