Problems solved by technology

Although there is a mechanical emergency release, a locking pin thus secured may not be unlocked or may only be unlocked with great effort
In order to solve the above-mentioned problems, only expensive protection of charging sockets against moisture has hitherto been possible
Furthermore, the locking pins used hitherto have relatively high wear and possibly insufficient mechanical strength, thereby adversely affecting the function of the locking device and, in extreme cases, leading to failure of the locking device

Abstract

The invention relates to a charging socket (1) with a locking device for an electric vehicle. The charging socket is used for receiving a charging plug of a charging device and comprises a charging socket-side contact bushing (5) for inserting a charging plug-side contact pin and at least one charging socket-side locking pin (7), wherein the locking pin (7) can be moved into and out of a receiving space region (4) of the charging socket (1) transversely to the insertion direction by means of a controllable locking drive (6). The locking pin (7) in the locking position when the charging plug is inserted is engaged in the associated locking structure in order to prevent the charging plug from being accidentally disconnected. According to the invention, the locking pin (7) is made of polyphthalamide (PPA).

Description

Technical field [0001] The present invention relates to an electric vehicle having a charging socket having a locking device for receiving a charging plug of a charging device having a contact bushing having a charging socket side for inserting a contact pin on the charging plug side and at least A locking pin on a charged socket side, the locking pin through the controlled lock driver to move into and remove the accommodating space area of ​​the charging socket in the insertion direction, wherein the locking pin in the locked position is inserted when the charging plug is inserted. This is embedded to the matching structure to prevent the charging plug from being disconnected unexpectedly. The term electric vehicle is used herein as a collective of all vehicles with rechargeable traction batteries. Background technique [0002] A charging sleeve having a locking device having a locking device for an electric vehicle according to the present invention is known from DE 10201 20044...
