Description
Technical Field
The invention belongs to the technical field of electric vehicle power supply, and particularly relates to a feed connector of a segmented continuous ground power supply system of an electric vehicle.
Background
The electric vehicle is supplied with electricity on the ground continuously in a segmented mode, and the electricity is supplied for over one hundred years since the first time the german patent 12593 is proposed in 1900. Although this solution has many advantages such as canceling overhead network cable, facilitating safe access, and being beneficial to urban landscape, it still has some technical problems that are not solved, thereby hindering practical application. For a long time, efforts have been focused on how to ensure the safety of the power feeding equipment to the surrounding environment. In the last 90 s of the century, european patent EP-B-0761493 proposed a modular feeding scheme, which better solved this problem. The contribution of this scheme is: when the vehicle approaches, the conductor element of the module is disconnected from the ground potential by means of the action of a magnetic pickup device on the vehicle, and the positive feeder is connected with the conductor element of the module; when the vehicle moves away, the magnetic pickup device on the vehicle is lost, the feeder is disconnected from the conductor element of the module, and the conductor element of the module is restored to the ground potential. Even so, the segmented continuous ground power supply for electric vehicles has not reached a large-scale commercial application until now. One important reason for this is that the connection of the feeder module to the bus cable is not solved. In the prior art, the connection between the bus cable and the feeder module is generally implemented by arranging a pin on the bus cable and a socket on the feeder module. However, the installation of the contact pin on the field cable not only has extremely strict requirements on the position, but also has extremely poor effect of field waterproof insulation treatment. Therefore, the underground bus cable is laid only by adopting a sectional connection mode. The cable is segmented corresponding to the distance between adjacent feed modules, a contact pin for connecting the feed modules is fixed on the cable segment under factory conditions, and waterproof insulation treatment is performed; and then abutting the adjacent cable sections through the terminals on site, and performing waterproof insulation treatment on the connecting points. By adopting the scheme, the field construction process is complex, the cost is consumed, and the number of fault points is increased due to excessive cable contacts; more seriously, during the operation of the vehicle, the pins on the cable sections are often loosened by the vibrations of the feeder module. Thus, in the underground severe environment, faults such as electric leakage, smoke generation and the like are often caused by moisture and water, and the normal operation of the vehicle is affected. In addition, the time and difficulty of maintenance are also increased.
Disclosure of Invention
The present invention is directed to overcome the above-mentioned deficiencies of the prior art and to provide a feeding connector for a sectionally continuous ground power supply system of an electric vehicle.
The purpose of the invention is realized as follows: the utility model provides an electric vehicle segmentation continuous type ground power supply system feed connector, includes that one is just, negative contact pin, positive, negative contact pin can realize the electricity with positive, negative socket butt joint on the feed module and be connected, its characterized in that positive, contact pin draw back the distance through telescopic flexible transition cable respectively and are connected with positive, negative bus cable.
Furthermore, the inner surface of the connecting end of the flexible transition cable is an arc surface with the same radius as the outer surface of the bus cable core, the coupling block structure with the insulating layer on the inner surface surrounds the bus cable core, and the inner surface of the connecting end is pressed on the outer surface of the bus cable core through a bolt so as to realize electric connection.
Furthermore, the insulating layer is made of silicon rubber materials, and the shapes of the two ends of the inner surface of the insulating layer are matched with the fracture of the protective layer of the bus cable.
According to the technical scheme, the bus cable does not need to be installed in a segmented mode corresponding to each feeder module, butt joints of the bus cable are greatly reduced, and the bus cable feeder is convenient to install and simple in process. The looseness phenomenon of the contact pin on the cable section caused by the vibration of the feed module is avoided. The distance between the positive connecting point and the negative connecting point can be properly enlarged, and faults of electric leakage, smoke generation and the like caused by moisture and water soaking are greatly reduced.
