Abstract

The invention relates to a vehicle-side socket of a charging connector, in particular for industrial vehicles, comprising a first main contact and a second main contact, which are adapted to be connected to a charging connector, as well as an auxiliary contact, which, in the operating condition of the vehicle, with the charging connector removed, is electrically connected to one of the main contacts via a contact bridge, the contact bridge having a first end captively connected to the auxiliary contact and being adapted to be transferred from a first position, at which said main contact is free for attaching the charging connector thereto, to a second position, at which the contact bridge connects the auxiliary contact to said main contact.

Claims

1. A vehicle-side socket (1) of a charging connector, in particular for industrial vehicles, comprising a first main contact (2) and a second main contact (3), which are adapted to be connected to a charging connector, as well as an auxiliary contact (5) which, in the operating condition of the vehicle, with the charging connector removed, is electrically connected to one of the main contacts (2, 3) via a contact bridge (4), characterized in that the contact bridge (4) has a first end (15) captively secured to the auxiliary contact (5) and is adapted to be transferred from a first position, at which said main contact (2, 3) is free for attaching the charging connector thereto, to a second position, at which the contact bridge (4) connects the auxiliary contact (5) to said main contact.

2. A vehicle-side socket (1) according to claim 1, characterized in that the first end (15) of the contact bridge (4) merges with a first contact pin (14) connected to the auxiliary contact (5), and/or that, for contacting said one of the main contacts (2, 3) at the second position, a second end (17) of the contact bridge (4) merges with a second contact pin (16).

3. A vehicle-side socket (1) according to claim 2, characterized in that the first and second main contacts (2, 3) are configured as two contact bushings arranged, with respect to their longitudinal axes (6, 7), substantially in parallel side by side and/or parallel to a longitudinal axis (23, 25) of the first contact pin (14) and/or of the second contact pin (16).

4. A vehicle-side socket (1) according to claim 2, characterized in that, for switching from the first position to the second position, the contact bridge (4) is adapted to be displaced axially along the longitudinal axis (23) of the first contact pin (14) to a first intermediate position and to be rotated to a second intermediate position, the second contact pin (16) being displaceable from said second intermediate position to the second position.

5. A vehicle-side socket (1) according to claim 1, characterized in that the auxiliary contact (5) is secured in position by means of a spring element (18) at the second position and at the first position.

6. A vehicle-side socket (1) according to claim 2, characterized in that the contact bridge (4) includes a flange portion (20) between the first and second ends (15, 17), said flange portion (20) being oriented transversely to the longitudinal axis (23, 25) of the first and/or second contact pin (14, 16).

7. A vehicle-side socket (1) according to claim 2, characterized in that the contact bridge (4) is supported such that it is rotatable about the longitudinal axis (23) of the first contact pin (14), and that, for switching the contact bridge (4) from the first position to the second position, said contact bridge (4) is rotated about the longitudinal axis (23) of the first contact pin (14).
