a first ramp element;
a second ramp element;
an intermediate element with two opposing ends, a first end of the intermediate element being connected to the first ramp element and a second end of the intermediate element being connected to the second ramp element; and
an articulating connection arranged between the first ramp element and the intermediate element,
wherein, in the transport state, the first ramp element and the intermediate element are folded and the second ramp element constitutes an extension of the intermediate element.
2. The bridge according to claim 1, wherein, in the transport state, the first ramp element is situated on top of the intermediate element and the first ramp element has approximately the same length as the intermediate element.
3. The bridge according to claim 1, wherein, in the transport state, the first ramp element is situated on top of the intermediate element and the first ramp element has a lesser or greater length than the intermediate element.
4. The bridge according to claim 1, wherein the first and second ramp elements have a predetermined length and the length of the intermediate element is changeable.
5. The bridge according to claim 1, wherein, in the installation state, the first ramp element and the intermediate element are unfolded.
6. The bridge according to claim 1, wherein the intermediate element and the second ramp element are connected to each other via a locking hinge.
7. The bridge according to claim 1, wherein the second ramp element has a free end connected in an articulating manner to a pivot arm of a transport vehicle.
8. An installation vehicle comprising a bridge according to claim 1.
9. The installation vehicle according to claim 8, wherein the transport vehicle has a support element on which the bridge is supported during transport.
10. The installation vehicle according to claim 8, wherein a pivot arm is provided in a front region of the vehicle.
The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. An electrical connector comprising:
an insulating housing mounting a plurality of terminals thereon;
a metallic shell comprising a pair of opposite sidewalls and a pair of endwalls interconnecting with the side walls, thereby defining a receiving space surrounding the housing, each endwall defining a pair of locking portions respectively at opposite sides thereof and a holding portion on a rear portion thereof;
a pair of retaining devices, each comprising a main body with a nut therein and an extending board extending rearwards from the main body thereof, and
wherein the main body of each retaining device defines a channel therein and leaves a stopping portion in a rear end, the corresponding locking portion being inserted into the channel and abutting against the stopping portion, and the holding portion pressing against a rear portion of the extending board.
2. The electrical connector as described in claim 1, wherein the insulating housing comprises a main body and a pair of protrusion portions extend outwardly from opposite ends of the main body along a longitudinal direction, a pair of front-protruding tabs extending forward from lateral ends of each protrusion portion to suppress the extending board of each retaining device.
3. The electrical connector as described in claim 2, wherein the holding portion of the shell is received in an aperture defined between the pair of front-protruding tabs when the insulating housing is mounted in the shell.
4. An electrical connector comprising:
an insulative housing defining an elongated main body with two opposite retaining sections at two longitudinal ends, and with a mating tongue extending forwardly from a middle portion of the main body;
a metallic shell defining opposite upper and bottom faces and opposite two end faces commonly defining a space receiving said mating tongue;
a pair of mounting ears discrete from said housing and said shell and assembled to the shell, said shell defining first and second gripping sections respectively grasping the main body and the corresponding mounting ear; wherein
said retaining section blocks rearward movement of the corresponding mounting ear therein said shell further includes an abutment section blocking backward movement of the corresponding mounting ear and sandwiched between the corresponding mounting ear and the corresponding retaining section in a front-to-back direction.
5. The electrical connector as claimed in claim 4, wherein said second gripping section defines a channel only allowing forward assembling of the mounting ear with regard to the shell, and the abutment section is bent to a final position only after the mounting ear has been filly assemble to the shell.
6. The electrical connector as claimed in claim 4, wherein said retaining section has one portion directly engaging the corresponding mounting ear and another portion directly engaging the corresponding abutment section of the shell.
7. An electrical connector comprising:
an insulative housing having a base portion and a mating tongue extending from the base portion, a plurality of contacts extending from the base portion to the mating tongue;
a metallic shell attached to the base portion and substantially enclosing the mating tongue for receiving a mating connector therein, the metallic shell having transversal end walls and each including first and second locking tabs extending face-to-face from opposite edges thereof and offset from each other, and jointly defining a retaining space therein;
a pair of retaining devices discrete from said insulating housing and said metallic shell and assembled to said metallic shell, each of said pair of retaining devices including an extending board securely retained in the retaining space and a main body projecting out of the retaining space; and
a third locking tab extending from the end wall to prevent the extending board from escaping from the retaining space.
8. The electrical connector as described in claim 7, wherein a pair of retaining sections are respectively formed at two longitudinal ends for further blocking the rearward movement of the retaining devices.
