In one possible implementation, the groove 3021 is hemispherical, see the groove shown in fig. 3, where the female contact 302 is a female round contact.

Because the elastic contact is of an elastic structure, when the motor train unit is reconnected, an elastic contact mode is adopted, so that bending deformation and even fracture of a contact pin caused by the inclination of connecting noodles of the electric coupler connector can be prevented, the possibility of signal loss in the electric coupler connector is reduced, and the operation reliability of the heavy-duty car unit is improved.
Based on the electrical coupler connector provided by the foregoing, the embodiment of the application further provides a heavy-duty train unit, which includes a first motor train unit and a second motor train unit, and the first motor train unit and the second motor train unit are reconnected through the electrical coupler connector provided by the corresponding embodiment of fig. 3.
Based on the description of the corresponding embodiment of fig. 3, the electrical coupler connector includes two parts, namely, the elastic contact 301 and the concave contact 302, which are close to each other to form elastic contact, so that reconnection of the motor train unit can be achieved. Thus, in general, the spring contact 301 and the female contact 302 included in one of the electrical coupler connectors are mounted on the first and second motor train units, respectively, and if the spring contact 301 included in one of the electrical coupler connectors is mounted on the first motor train unit, the female contact 302 included therein is required to be mounted at a corresponding position on the second motor train unit so that the two can be elastically contacted. If the female contact 302 included in one air coupler connector is mounted on a first motor train unit, then the resilient contact 301 included therein needs to be mounted at a corresponding location on a second motor train unit so that the two can be resiliently contacted.
It is understood that in order to achieve a heavy linkage of the first and second motor train units, a plurality of electrical coupler connectors may be mounted on the first and second motor train units. The manner in which the electrical coupler connectors are mounted on the first and second motor train units may include a variety of types.
In one possible implementation, the spring contacts 301 or the female contacts 302 may all be mounted on the same motor train unit. For example, the first motor train unit includes a first number of elastic contacts 301, the second motor train unit includes a first number of concave contacts 302, and the first number of elastic contacts 301 corresponds to the first number of concave contacts 302 one by one.
In one possible implementation, both the spring contact 301 and the female contact 302 may be mounted on the same motor train unit. For example, the first motor train unit includes a first number of elastic contacts 301 and a second number of concave contacts 302, the second motor train unit includes a first number of concave contacts 302 and a second number of elastic contacts 301, the first number of elastic contacts 301 are in one-to-one correspondence with the first number of concave contacts 302, and the second number of concave contacts 302 are in one-to-one correspondence with the second number of elastic contacts 301. The first number and the second number may be the same or different, and this embodiment is not limited thereto.
Referring to fig. 3, in fig. 3, taking an example that the first motor train unit is motor train unit 1 and the second motor train unit is motor train unit 2, elastic contacts 301 and concave contacts 302 are simultaneously installed on the motor train unit 1 and the motor train unit 2. The upper rectangular box in fig. 3 shows the distribution of the elastic contacts 301 and the concave contacts 302 on the motor train unit 1, the circles marked 1, 2, 4, 5, 7, 8 in the area marked a in fig. 3 show the elastic contacts 301, and the circles marked 1, 2, 4, 5, 7, 8 in the area marked B in fig. 3 show the concave contacts 302, where the first number is 6 and the second number is also 6; the rectangular box below in fig. 3 shows the distribution of the elastic contacts 301 and the concave contacts 302 on the motor train unit 2, the circles marked 1, 2, 4, 5, 7, 8 in the area marked C below in fig. 3 show the concave contacts 302, and the circles marked 1, 2, 4, 5, 7, 8 in the area marked D below in fig. 3 show the elastic contacts 301, where the first number is 6 and the second number is also 6.
The elastic contacts 301 in the area marked by A and the concave contacts 302 in the area marked by C correspond to each other one by one to form an electric coupler connector; the female contacts 302 in the area identified by B and the resilient contacts 301 in the area identified by D are in one-to-one correspondence to form an electrical coupler connector.
By installing the elastic contact 301 and the concave contact 302 on the same motor train unit, the elastic reliable contact of the electric coupler connector can be improved, and the operation reliability of the heavy-duty motor train unit can be further improved.
When the first motor train unit and the second motor train unit are required to be reconnected, one motor train unit is controlled to be stationary through the control room, and the other motor train unit approaches to the stationary motor train unit until the elastic contact 301 and the concave contact 302 are in elastic contact, and particularly the springs in the elastic contact 301 are in a compressed state, so that the contact is ensured.
Taking the example that the first motor train unit is the motor train unit 1 and the second motor train unit is the motor train unit 2, when the motor train unit 1 and the motor train unit 2 are reconnected through the electric coupler connector, the elastic contact 301 and the concave contact 302 included in the electric coupler connector are in a connection state through elastic contact, and the connection state is shown in fig. 4.
It should be noted that, in this embodiment, in the reconnection process of the motor train unit, the electrical coupler connector formed by the elastic contact 301 and the concave contact 302 may be used for transmitting signals. The transmitted signals may include traction signals, braking signals, door control signals, pantographs, safety loops, network signals, passenger information system (Passenger Information System, PIS) signals, etc., and may enable a control room to safely control the heavy train consist.
In one possible implementation, the electrical coupler connectors for reconnecting the first and second motor train units include a plurality of different electrical coupler connectors for transmitting different signals, i.e., each electrical coupler connector may be used to transmit a single signal at that time. For example, in fig. 4, two elastic contacts 301 on the motor train unit 1 and two concave contacts 302 on the motor train unit 2 may respectively implement elastic contact, where, from the left side in fig. 4, a first elastic contact 301 on the motor train unit 1 and a first concave contact 302 on the motor train unit 2 may transmit a signal 1; the second elastic contact 301 on the motor train unit 1 and the second concave contact 302 on the motor train unit 2 can transmit signals 2; from the right side in fig. 4, the first concave contact 302 on the motor train unit 1 and the first elastic contact 301 on the motor train unit 2 can transmit the signal 3; the second female contact 302 on EMUs 1 and the second resilient contact 301 on EMUs 2 can transmit signal 4.
In one possible implementation, the electrical coupler connectors for reconnecting the first and second motor train units include a plurality. In order to avoid signal loss in the electric coupler connectors and further lead to grouping signal faults in the heavy linkage vehicle group and influence the operation reliability of the heavy linkage vehicle group, in the embodiment, a plurality of electric coupler connectors are symmetrically arranged, and two mutually symmetrical electric coupler connectors are used for transmitting the same signal. The double-path redundant signal transmission mode is adopted, and even if one path of signal is lost, the safety control of the heavy linkage vehicle group can be realized through the other path of signal, so that the grouping signal fault in the heavy linkage vehicle group caused by the signal loss in the electric coupler connector is avoided, and the operation reliability of the heavy linkage vehicle group is improved.
In some cases, since the electrical coupler connector can also transmit network signals, and in the electrical coupler connector formed by the elastic contact 301 and the concave contact 302, since the elastic contact 301 includes the spring 3011, the spring 3011 corresponds to an inductance in a signal transmission process, and may affect a frequency of the network signals. In order to reduce the influence on the network signals, in one possible implementation manner, the first motor train unit can further comprise a third number of pins, the second motor train unit can further comprise a third number of jacks, the third number of pins are in one-to-one correspondence with the third number of jacks, and the first motor train unit and the second motor train unit are further reconnected through an electric coupler connector formed by the pins and the jacks; and/or, the first motor train unit further comprises a fourth number of jacks, the second motor train unit further comprises a fourth number of contact pins, the fourth number of contact pins and the fourth number of jacks are in one-to-one correspondence, and the first motor train unit and the second motor train unit are further reconnected through an electric coupler connector formed by the contact pins and the jacks.
Referring to fig. 4, taking the example that the first motor train unit is the motor train unit 1 and the second motor train unit is the motor train unit 2, the motor train unit 1 and the motor train unit 2 can be reconnected through an electric coupler connector formed by the contact pin 101 and the jack 102 in addition to the electric coupler connector formed by the elastic contact 301 and the concave contact 302. In fig. 4, the third number and the fourth number are both 1. At this time, the electrical coupler connector formed by the pin 101 and the jack 102 is used for transmitting network signals.
It should be noted that, the signal transmission of the electrical coupler connector is realized by adopting the signal transmission mode with two-way redundancy, which can be seen in fig. 5, the first motor train unit is the motor train unit 1, the second motor train unit is the motor train unit 2, the motor train unit 1 includes two elastic contacts 301, one jack 102, one contact pin 101 and two concave contacts 302, and the motor train unit 2 includes two concave contacts 302, one contact pin 101, one jack 102 and two elastic contacts 301. The elastic contact 301 marked as 1 on the motor train unit 1 and the concave contact 302 marked as 1 on the motor train unit 2 form an electric coupler connector for transmitting signals 1; the female contact 302 identified as 1 on EMUs 1 and the resilient contact 301 identified as 1 on EMUs 2 form an electrical coupler connector, which is also used for transmitting signal 1. An elastic contact 301 marked as 2 on the motor train unit 1 and a concave contact 302 marked as 2 on the motor train unit 2 form an electric coupler connector for transmitting signals 2; the female contact 302 identified as 2 on EMUs 1 and the resilient contact 301 identified as 2 on EMUs 2 form an electrical coupler connector, which is also used for transmitting signals 2. Jack 102 marked 3 on EMUs 1 and pin 101 marked 3 on EMUs 2 form an electric coupler connector for transmitting signal 3; pin 101 on EMUs 1, labeled 3, and jack 102 on EMUs 2, labeled 3, form an electrical coupler connector, also used to transmit signal 3.
The electric coupler connector shown in fig. 5 is used for reconnecting the motor train unit, and as the electric coupler connector formed by the contact pin and the jack is adopted in the middle and the electric connectors formed by the elastic contact and the concave contact are adopted at two sides, the middle electric coupler connector is stressed less, so that the contact pin can be prevented from bending or deforming as much as possible, and meanwhile, the normal transmission of network signals can be ensured. In addition, the signal transmission mode based on the double-circuit redundancy realizes the signal transmission of the electric coupler connector, can prevent the signal loss caused by poor contact of a single-circuit signal, and further improves the operation reliability of the heavy linkage vehicle group.
