Description

Technical Field

[0001] This utility model relates to the field of connecting line testing technology, specifically to a quick assembly and disassembly tooling for the connecting lines of the CR200J EMU. Background Technology

[0002] The connecting lines of high-speed trains bear critical functions such as signal transmission and power supply, and the correctness of their connection status directly affects the operational safety and performance of the high-speed trains. Accurate and efficient alignment work is crucial for timely detection and elimination of connecting line faults, ensuring the reliable operation of the high-speed trains.

[0003] The CR200J EMU has numerous and complexly distributed connecting wires, encompassing various types such as control connecting wires, multiple-unit connecting wires, and network connecting wires. Different types of connecting wires have different specifications and functions; for example, control connecting wires have 60 cores, multiple-unit connecting wires have 40 cores, and network connecting wires have 32 cores. Furthermore, there is one set of connecting wires between every two carriages, resulting in 48 connecting wires per train, increasing the time and difficulty of inspection. Inspection work requires accurately determining the correctness of the connection relationship of each connecting wire, including the conductivity of the wire cores and the relative positional relationships between different wires. At the same time, to avoid affecting the normal operation of the EMU, the inspection process should be as efficient as possible to minimize maintenance time.

[0004] When using a connection cable detection device to perform point detection on a connection cable, the connection cable needs to be connected to the connection cable detection device. However, since the connection cable has many core wires, it can cause problems such as inconvenience in connecting the connection cable to the connection cable detection device and difficulty in plugging and unplugging.

[0005] Therefore, a quick assembly and disassembly tooling for connecting cables is needed to reduce the difficulty of connecting cables to connecting cable detection devices and improve connection efficiency. Utility Model Content

[0006] To address the aforementioned issues, this utility model provides a quick assembly and disassembly tooling for the CR200J EMU connecting cable, which solves the problem of difficult cable insertion and can effectively improve the efficiency and accuracy of cable insertion.

[0007] Specifically, this utility model is implemented as follows:

[0008] A quick assembly and disassembly tooling for the connecting line of a CR200J EMU includes:

[0009] The first housing is installed on the signal line of the connection detection device;

[0010] A positioning component, detachably mounted at one end of the first housing, is used to position the connecting line;

[0011] A quick clamp, disposed on the first housing, is used to clamp the connecting wire so that the signal wire and the connecting wire can be plugged together.

[0012] Furthermore, the positioning component includes:

[0013] The positioning plate is detachably connected to the first housing.

[0014] The first positioning post is disposed on the positioning plate and is used to mate with the positioning hole on the connecting line. There are two first positioning posts, which are located on both sides of the positioning plate and are arranged diagonally.

[0015] Furthermore, the quick assembly and disassembly tooling for the CR200J EMU connecting line also includes a second housing, which is located inside the first housing and connected to the positioning plate;

[0016] The positioning component also includes:

[0017] A fixed plate is detachably connected to the second housing, and the signal line interface is connected to the fixed plate.

[0018] The first positioning cylinder is disposed at the interface of the signal line;

[0019] The second positioning post is located at the interface of the signal line. There are two of each of the first positioning cylinder and the second positioning post, which are symmetrically arranged on both sides of the interface of the signal line.

[0020] Furthermore, the quick clamp is a push-pull quick clamp, which is located on both sides of the first housing.

[0021] Furthermore, the push-pull quick clamp includes: a handle, a linkage mechanism, a clamping arm, and a chuck. The handle is connected to the clamping arm via the linkage mechanism. The chuck is located at the bottom of the clamping arm and is used to clamp the connector housing. A stop block is provided on the clamping arm. The stop block and the chuck are located at both ends of the connector housing, respectively.

[0022] Working principle:

[0023] The connector is male, and the signal cable is female. The fixture is located at the female connector of the signal cable. It is secured by a first housing and a positioning assembly. A first positioning post aligns with a hole on the connector, aligning the left and right positions of the connector and signal cable cores. Then, a first positioning cylinder and a second positioning post align with the positioning cylinder and post on the connector, ensuring the front and back of the connector and signal cable cores are aligned. After the connector is initially inserted into the signal cable, the chuck of the push-pull quick-release clamp presses against the end of the connector housing. Pulling the handle moves the chuck upwards, fully inserting the connector into the signal cable. Conversely, to remove the cable, pull the handle downwards, causing the chuck to move away from the signal cable. This allows for quick insertion and removal of the connector.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] (1) The quick-connect and disconnect tooling for the CR200J EMU connecting line provided by this utility model can realize the quick plugging and unplugging of the connecting line and the detection signal line, thereby improving the efficiency during detection.

[0026] (2) This utility model adopts a dual positioning method of horizontal positioning and positive and negative positioning, which effectively solves the problem caused by inaccurate positioning of the connecting line and the detection signal line and incorrect positive and negative positioning during docking, and can effectively improve the connection accuracy of the connecting line and the detection signal line.

Detailed Implementation

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0036] Example 1

[0037] like Figure 1-2 As shown, this embodiment provides a quick assembly / disassembly fixture for the connecting lines of a CR200J EMU, including: a first housing 1, a second housing 2, a positioning component, and a quick clamp (push-pull quick clamp 3). The first housing 1 has a rectangular structure with protruding ears on both sides for mounting the push-pull quick clamp 3. The first housing 1 is mounted entirely on the signal line 5 of the connecting line detection device, serving as the main frame of the fixture. The second housing 2 is located inside the first housing 1 and is connected to the positioning component, serving as a component for fixing the port of the signal line 5.

[0038] The positioning assembly includes: a positioning plate 41, a fixing plate 43, a first positioning cylinder 44, and a second positioning post 45. The positioning plate 41 is detachably connected to the first housing 1 by bolts. A first positioning post 42 is provided on each side of the positioning plate 41. The two first positioning posts 42 are arranged diagonally and correspond to the positioning holes on the connection interface housing 61 of the connecting line 6, respectively, to determine the unique assembly angle for the connection line 6 and the signal line 5 to be inserted, thereby ensuring the correctness of the insertion. The second housing 2 is nested inside the positioning plate 41, and the fixing plate 43 is nested inside the second housing 2. The interface of the signal line 5 is fixed to the fixing plate 43 by the first positioning cylinder 44 and the second positioning post 45. The ends of the first positioning cylinder 44 and the second positioning post 45 are both threaded and connected to the fixing plate 43 by the threads. There are two of each of the first positioning cylinder 44 and the second positioning post 45, which are symmetrically arranged along the interface axis. The first positioning cylinder 44 and the second positioning post 45 are respectively connected to the positioning components on the interface housing 61 of the connecting line (including the insertion post corresponding to the first positioning cylinder 44 and the insertion cylinder corresponding to the second positioning post 45), thereby realizing the positive and negative positioning of the connecting line 6 and the signal line 5, avoiding the problem of positive and negative errors. Together with the first positioning post 42, they form a double positioning structure to improve the accuracy of insertion.

[0039] like Figure 3As shown, the push-pull quick clamp 3 includes a handle 31, a linkage mechanism 32, a clamping arm 33, and a chuck 34. The handle 33 is connected to the clamping arm 33 via the linkage mechanism 32. The chuck 34 is located at the bottom of the clamping arm 33, and a stop block 35 is provided on the clamping arm 33. The stop block 35 and the chuck 34 are located at opposite ends of the connector interface housing 61. The linkage mechanism 32 converts the movement of the handle 31 into the displacement of the clamping arm 33, thereby displacing the stop block 35 and the chuck 34, causing the connector interface housing 61 to move accordingly, facilitating the insertion and removal of the connector cable 6 and the signal cable 5. It should be noted that during use, the push-pull quick clamp 3 needs to be rotated so that the chuck 34 overlaps with the connector interface housing 61 to ensure effective clamping of the connector interface housing 61 by the chuck 34.

[0040] Specifically, such as Figure 4-5 As shown, when connecting the cable 6 and the signal cable 5, first check the positioning component on the cable interface housing 61 to align it with the first positioning cylinder 44 and the second positioning post 45. Then, align the cable interface housing 61 with the positioning plate 41 and insert the first positioning post 42 into the positioning hole of the cable interface housing 61. Next, press down the handle 31 of the push-pull quick clamp 3. The clamping arm 33 is driven to move through the linkage mechanism 32, causing the clamp 34 to move upward and move the cable interface housing 61 closer to the positioning plate 41. At the same time, the pin of the cable 6 is inserted into the female end of the signal cable 5, completing the quick connection between the cable 6 and the signal cable 5.

[0041] When the two are separated, such as Figure 6 As shown, by turning the handle 31, the stop block 35 is driven to push the connector housing 61, forcing the female end of the signal line 5 to separate from the connector pin.

[0042] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
