Line connector for transmitting electric signals

A line connector for transmitting electric signals, comprising:

• a housing;
• a first electric connection configured to transmit a first electric signal;
• a second electric connection configured to transmit a second electric signal;
• and
• a diagnostic device configured to monitor the first electric signal and detect a first status of the first electric connection, and further configured to monitor the second electric signal and detect a second status of the second electric connection,
• wherein the housing has a housing wall with a first optical indicator and a second optical indicator, wherein the first optical indicator is configured to generate a first optical signal which represents the first status, and wherein the second optical indicator is configured to generate a second optical signal which represents the second status, and
• wherein the first optical indicator comprises a scattering element configured to transmit an optical signal of the first optical indicator starting from a surface normal axis of the housing wall with a scattering angle of up to 90°.
