Electric car coupler connector and reconnected motor train unit

Abstract

The invention discloses an electric car coupler connector and a heavy linkage car set. The electric car coupler connector comprises an elastic contact and a concave contact. The elastic contact comprises a spring, a spring fixing seat and a shell, the spring is located in the shell, the first end of the spring and the first end of the shell are inserted into the spring fixing seat, the spring fixing seat is used for fixing the first end of the spring, and the length of the first end of the shell inserted into the spring fixing seat is changed along with stretching of the spring; the concave contact is provided with a groove, and the groove is used for being in elastic contact with the elastic contact through the second end of the spring and the second end of the shell so that reconnection between motor train units can be achieved; and as the elastic structure is adopted in the elastic contact, an elastic contact mode is adopted during reconnection of the motor train units, bending deformation and even breakage of a contact pin caused by inclination of a connection surface of the electric car coupler connector can be prevented, the possibility of signal loss in the electric car coupler connector is reduced, and the operation reliability of the reconnected motor train unit is improved.

Description

technical field [0001] The present application relates to the field of EMUs, in particular to an electric coupler connector and reconnected EMUs. Background technique [0002] The reconnection of EMUs is a common operation mode of EMUs, that is, two EMUs of the same model are connected to each other, and the first EMU is responsible for the operation in the forward direction, and the second EMU is operated according to the first EMU. The group transmits the control signal to operate. [0003] As the main body of the electrical connection between the EMUs and the carriages, the electrical coupler connector adopts the form of fixed pins and jacks, which leads to the loss of signal in the electrical coupler connector, and causes the failure of the reconnection marshalling signal of the EMU. [0004] At present, in order to overcome these defects, the method of increasing the contact depth of the pins and sockets of the electric coupler connector is mainly used to improve the c...

[0003] As the main body of electrical connection between EMUs and carriages, the electrical coupler connector adopts the form of fixed pins and jacks, which leads to the loss of signal in the electrical coupler connector and causes the failure of the reconnection marshalling signal of the EMU

[0004] At present, in order to overcome these defects, the method of increasing the contact depth of the pins and sockets of the electric coupler connector is mainly used to improve the contact reliability. However, because the electric coupler connector has many contacts, it is easy to Causes the pins to bend and deform, causing the pins of the electrical coupler connector to break
