Description

Technical Field

[0001] This utility model relates to the field of electrical machinery technology, and in particular to a power supply cable for an analog instrument. Background Technology

[0002] The simulator is a dedicated piece of equipment equipped on a certain type of launch vehicle. It is primarily used to realize all functions of the launch vehicle during training and is a crucial and indispensable piece of equipment for completing the entire launch process. The simulator is mounted on the launch pad of the launch vehicle, which is mounted on the launch vehicle's rotating platform. During launch process training, the simulator rotates in the same direction and at the same speed as the launch pad and rotating platform. The cable supplying power to the simulator on the roof, which is located in the vehicle, also moves left, right, up, and down with the simulator. Because the currently used cable is a linear cable without telescopic capability, it cannot be retracted or extended in time during the simulator's movement, often getting stuck at the launch pad or rotating platform, causing the cable to break.

[0003] The cable plugs at both ends of the simulator's power supply cable are ordinary cable plugs, which are not strong enough to fix the connected cable. Furthermore, because the cable moves with the simulator, the tension between the cable and the plug increases, causing the solder joints between the cable and the plug pins to frequently detach.

[0004] A single launch procedure training session on the launch vehicle takes approximately 5 minutes. To ensure operators master the skills, frequent and repeated training is necessary. However, each training session requires powering the simulator on and off. Since the simulator is mounted on the roof of the launch vehicle, this requires trainees to climb from inside the vehicle to the roof, which is time-consuming and laborious. Therefore, a solution is urgently needed.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0027] Example

[0028] See Figure 1-5 As shown: This utility model provides a power supply cable for an analog instrument, including: a power supply cable 10, a connector 20, a line switch 12, and a line control component.

[0029] There are two connectors 20, which are connected to both ends of the power supply cable 10 respectively. The two connectors 20 are respectively connected to the power interface on the simulator and the power socket in the launch vehicle compartment to supply power to the simulator.

[0030] The line switch 12 is installed on the power supply cable 10 to control the power supply cable 10 to be energized and de-energized. The line switch 12 is located near the connection between the power socket and the connector 20 inside the launch vehicle.

[0031] In practical applications, operators do not need to leave the launch vehicle. They only need to press the circuit switch 12 to turn the power supply cable 10 on or off, thereby quickly controlling the power supply and de-energization of the simulator. After the launch vehicle completes a launch procedure training, the simulator is first de-energized by the circuit switch 12 and then re-energized to prepare for the next training session, which is convenient and efficient.

[0032] The line control component is installed on the power supply cable 10 and the connector 20 to adjust the length of the power supply cable 10 and to reinforce the connection between the power supply cable 10 and the connector 20.

[0033] The line control component includes a spiral coil section 11; the spiral coil section 11 is disposed on the power supply cable 10 and is close to the connector 20 and the power interface on the simulator. The spiral coil section 11 is provided with a memory alloy coil that can be automatically reset. The memory alloy coil is used to automatically extend or retract the bus length of the power supply cable 10 during the movement of the simulator.

[0034] In practical applications, due to the setting of the spiral coil section 11, the length of the power supply cable 10 can be adjusted by itself, so that the entire power supply cable 10 has elasticity, avoiding the problem of cable jamming and breakage caused by the power supply cable 10 not being retracted or extended in time when the simulator rotates with the rotary platform.

[0035] The line control assembly also includes a fixed latching part and a movable latching part. The fixed latching part is disposed on the connector 20 and forms a latching connection with the power supply cable 10, which is used to reinforce the connection point between the power supply cable 10 and the connector 20; the movable latching part forms a sliding connection with the power supply cable 10 and a detachable connection with the outer shell of the launch vehicle.

[0036] The connector 20 mainly consists of a socket 21, a connector housing 22, a cable connection housing 23, and a cable clamp housing 24. One end of the socket 21 is plugged into the power interface on the simulator and the power socket inside the launch vehicle, while the other end is threaded into one end of the connector housing 22. The connector housing 22 protects the electrical connection between the power cable 10 and the socket 21, and the other end of the connector housing 22 is threaded into one end of the cable connection housing 23; the other end of the cable connection housing 23 is fixedly connected to one end of the cable clamp housing 24.

[0037] The fixed locking part includes an upper semi-circular arc card 241 and a lower semi-circular arc card 242. The cable locking housing 24 is fitted onto the power supply cable 10; one side of the lower semi-circular arc card 242 is fixedly connected to the end of the cable locking housing 24, and one end of the lower semi-circular arc card 242 is hinged to one end of the upper semi-circular arc card 241; a bolt 243 is installed on the other end of the upper semi-circular arc card 241; the bolt 243 and the through hole provided on the other end of the lower semi-circular arc card 242 form a threaded connection, and the upper semi-circular arc card 241 and the lower semi-circular arc card 242 form a locking connection with the power supply cable 10.

[0038] In practical application, the operator first passes the end of the power supply cable 10 through the cable clip housing 24, the cable connection housing 23, and the connector housing 22 in sequence and then makes an electrical connection with the socket 21. Then, the cable connection housing 23, the connector housing 22, and the socket 21 are connected to each other in sequence by means of threaded connection. Finally, the upper semi-circular card 241 and the lower semi-circular card 242 are clipped onto the power supply cable 10 and fixed with bolts 243.

[0039] The movable latching part includes a flexible kit 30 and a hook 40; the flexible kit 30 is fitted onto the power supply cable 10 and can move along the length of the power supply cable 10; one end of the hook 40 is plugged into the flexible kit 30, and the other end is latched onto the outer shell of the launch vehicle.

[0040] The elastic kit 30 includes a soft rubber sleeve 31 and a plug-in rubber sleeve 32. The soft rubber sleeve 31 has a cable hole 311 in the middle for the power supply cable 10 to pass through; one side of the plug-in rubber sleeve 32 is connected to one side of the soft rubber sleeve 31, and the middle of the plug-in rubber sleeve 32 has a compression hole 321 for the end of the hook 40 to be inserted.

[0041] The mounting component 40 includes a plug block 41, a connecting rope 42, and a hook 43; the diameter of the plug block 41 is larger than the diameter of the compression hole 321, and it is inserted into the plug sleeve 32; the two ends of the connecting rope 42 are respectively connected to the hook 43 and the plug block 41; the hook 43 is engaged with the outer shell of the launch vehicle.

[0042] In practical application, after the power supply cable 10 is installed, the operator adjusts the position of the soft rubber sleeve 31 on the power supply cable 10 according to the distribution of the power supply cable 10 on the outer shell of the launch vehicle. Then, the plug block 41 is inserted into the plug rubber sleeve 32. The plug block 41 in the plug rubber sleeve 32 squeezes the soft rubber sleeve 31, so that the soft rubber sleeve 31 can no longer slide along the length direction of the power supply cable 10. Thus, after the hook 43 is engaged with the outer shell of the launch vehicle, the position of the power supply cable 10 can be fixed.

[0043] Alternatively, the movable snap-fit ​​part can be configured as a nylon self-adhesive cable tie wrapped around the outside of the power supply cable 10.

[0044] The movable snap-fit ​​part can provide multiple stress points for the power cable 10, thereby reducing the tension of the power cable 10 on the connector 20 during use, preventing the power cable 10 from falling off the connector 20, and improving the durability of the power cable 10.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
