Description
Technical Field
The utility model relates to a rail vehicle basic unit field, concretely relates to connector connection state feedback device for locomotive.
Background
The electric locomotive adopts the reconnection line and the connector to transmit signals and electric energy between two or more sections. During the locomotive marshalling or decompiling process, the connectors between the two cars need to be connected or disconnected. One end of the connector is a male pin, and the other end of the connector is a female pin.
Connectors have widely used non-centrosymmetric structures to prevent errors, but it is unclear whether the internal male pin is well connected with the female pin after the two ends of the connector are buckled. For example, in a HXD1 locomotive, nearly 30 wires are connected in one connector, and the situation that the connection between a male pin and a female pin is poor often exists. The contact pin is deflected, the contact pin is withdrawn, even the contact pin is broken, and the like, and the locomotive communication fault is caused by poor connection. Because the bad connection can not be found in time, the fault can be cleared only by waiting for a section of the locomotive to report the fault, and the normal use of the locomotive is seriously influenced.
If when the connector is buckled, the connection state of the male contact pin and the female contact pin can be fed back quickly. The error can be corrected in time to ensure that each connection is good.
SUMMERY OF THE UTILITY MODEL
For solving the problem that the connection state can't be fed back to current connector among the background art, the utility model provides a connector connection state feedback device for locomotive, concrete technical scheme is as follows.
A connector connection state feedback device for a locomotive comprises a pin pair, wherein the pin pair comprises a male pin and a female pin, the male pin is provided with a pin body, and the female pin is provided with a pin hole into which the pin body can be inserted; further comprising:
the travel switch is arranged on the inner wall of the pinhole; the travel switch is in a first state when the needle body is inserted into the needle hole and is in a second state when the needle body is not inserted into the needle hole;
and the state display is in communication connection with the travel switch and is used for displaying the state of the travel switch.
With the above structure, when the needle body is inserted into the needle hole, the travel switch is pressed to enter the first state (communication); when the needle body is not inserted into the needle hole, the travel switch resets to enter a second state (disconnection), and the on-off state of the travel switch is displayed through the state display, so that the feedback of the connection state of the connector is realized.
Preferably, travel switch includes the travel switch body and locates the action end on the travel switch body, the travel switch body is installed on the inner wall of pinhole, the action end is followed the radial direction action of pinhole.
Preferably, the pin pairs are provided in plurality, and each pin pair is provided with the travel switch; each travel switch is in communication connection with the state display, and the state display is used for displaying the state of each travel switch.
Preferably, the device also comprises a controller and an alarm; the controller is respectively in communication connection with the state display and the alarm and is used for controlling the alarm to give an alarm when the states displayed by the state display are inconsistent. When the connector is disconnected, the state of each travel switch displayed by the state display should be the second state (disconnected). When the connectors are normally connected, the status display displays that the status of each travel switch should be the first status (on). When the states displayed by the state display are inconsistent, namely the states of part of the travel switches are displayed as the first state, and the states of part of the travel switches are displayed as the second state, the situation that the pins corresponding to the second state are connected abnormally is shown.
Owing to adopted above technical scheme, compare with prior art, the utility model discloses can the every contact pin of audio-visual feedback be to whether correctly connecting. When a certain male pin cannot be correctly inserted into the female pin due to deflection, pin withdrawal or pin breakage, the display of the state display can be quickly identified, and the alarm can remind maintenance personnel to correct the pin in time, so that good connection of each pair of pins is ensured, locomotive application faults caused by poor connection of the connector are avoided, and the utilization rate of the elevator is reduced.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Example 1
Referring to fig. 1 to 3, a connector connection state feedback device for a locomotive includes a pin pair including a male pin 1 and a female pin 2, the male pin 1 having a pin body 11, the female pin 2 having a pin hole 21 into which the pin body 11 is inserted; further comprising:
The state display 4 is in communication connection with the travel switch 3 and is used for displaying the state of the travel switch 3;
as shown in fig. 2 and 3, when the needle body 11 is inserted into the needle hole 21, the state indicator 4 indicates that the stroke switch 3 is in the first state (on). When the needle body 11 is not inserted into the needle hole 21, the state indicator 4 indicates that the stroke switch 3 is in the second state (off). In this embodiment, the status indicator represents the first status with green, and the second status with red.
In use, the status display should appear red when the connector is disconnected (i.e. the needle 11 is not inserted into the needle hole 21). When the connector is normally connected (i.e., the needle 11 is inserted into the needle hole 21), the status display shows green. When the needle body 11 is inserted into the needle hole 21 and the status indicator shows red, it indicates that the connector is abnormal.
Example 2
A connector connection state feedback device for a motorcycle, as shown in fig. 7, includes a plurality of pin pairs in embodiment 1, each of which is mounted with the stroke switch 3. Each travel switch 3 is in communication connection with the status display 4, and the status display 4 is used for displaying the status of each travel switch 3.
