## Abstract

The invention concerns a device for absorbing electrical noise on lines, with a housing having two housing parts, wherein each housing part is provided for receiving an element of a noise-absorbing material, wherein in the closed state, the housing has a passage opening in each of two opposing end walls for one or more lines, wherein the elements in the housing parts in the closed state of the housing form a passage for one or more lines, wherein the passage openings in the housing and the passage formed by means of the elements define a passage direction for the at least one line, and wherein a locking device is provided for locking the housing parts in the closed state of the housing, wherein the housing parts are configured such that by means of a relative movement of the housing parts with respect to each other, wherein a main component of the relative movement runs parallel to the passage direction, the housing parts can be moved into the closed state of the housing and locked together in the closed state.

## Claims

### Claim 1

A device for absorbing electrical noise on lines, comprising:
a housing having two housing parts,
wherein each housing part is provided for receiving an element of a noise-absorbing material,
wherein in the closed state, the housing has a passage opening in each of two opposing end walls for one or more lines,
wherein the elements in the housing parts in the closed state of the housing form a passage for one or more lines,
wherein the passage openings in the housing and the passage formed by means of the elements define a passage direction for the at least one line,
wherein a locking device is provided for locking the housing parts in the closed state of the housing,
wherein the housing parts are configured such that by means of a relative movement of the housing parts with respect to each other,
wherein a main component of the relative movement runs parallel to the passage direction, the housing parts can be moved into the closed state of the housing and locked together in the closed state, and
wherein the housing is divided obliquely to the passage direction by means of the housing parts.

### Claim 2 (depends on 1)

A device according to claim 1, wherein the two housing parts are formed identically.

### Claim 3 (depends on 1)

A device according to claim 1, wherein in the closed state of the housing, the elements are divided obliquely to the passage orientation.

### Claim 4 (depends on 1)

Device A device according to claim 1, wherein the housing parts are provided with a sliding guide.

### Claim 5 (depends on 4)

A device according to claim 4, wherein the sliding guide is formed as a sliding block guide.

### Claim 6 (depends on 4)

A device according to claim 4, wherein the sliding guide is configured as a linear guide by means of guide strips.

### Claim 7 (depends on 1)

A device according to at least one of the preceding claim 1, wherein the locking device comprises latching means with latching protrusions and latching recesses.

### Claim 8 (depends on 7)

A device according to claim 7, wherein the latching means are arranged separately from the sliding guide.

### Claim 9 (depends on 7)

A device according to claim 7, wherein the latching means have sprung latching arms.

### Claim 10 (depends on 7)

A device according to claim 7, wherein the latching means are arranged on the sliding guide.

### Claim 11 (depends on 10)

A device according to claim 10, wherein the latching means have at least one latching recess in the sliding guide.

### Claim 12 (depends on 1)

A device according to claim 1, wherein at least one of the elements is provided with at least one approach chamfer, wherein the approach chamfer runs on the respective other element during the relative movement from the open state to the closed state of the housing.

### Claim 13 (depends on 1)

A device according to claim 1, wherein a spring device is provided between a respective element and the assigned housing part in order to pretension the element in the direction of the element in the other housing part when the housing is closed.

### Claim 14 (depends on 13)

A device according to claim 13, wherein the spring device comprises a leaf spring.

### Claim 15 (depends on 1)

A method for arranging a device according to claim 1 on at least one electrical line, comprising:
moving of the two housing parts of the housing of the device into the closed state of the housing by means of a relative movement of the two housing parts with respect to each other.
