[0002] Currently, in the traditional rail passenger car manufacturing process, after the operator connects a terminal larger than 10 square meters to the socket, if the terminal needs to be removed due to material quality problems or terminal crimping errors, conventional manual needle extraction tools cannot meet the requirements. Moreover, if the operator uses brute force to remove the terminal, the terminal and the socket are easily damaged due to uneven force. Therefore, the conventional solution is for the operator to cut off the terminal, discard the socket, re-crimp and install it. This operation not only wastes materials and increases vehicle manufacturing costs, but also reduces production efficiency and prolongs the vehicle completion cycle, which is not in line with the lean concept.

[0003] Therefore, based on the above problems, it is necessary for the present invention to provide a large-wire needle extraction tool for solving the problem of needing to extract the needles after crimping terminals on cables with a size of more than 10 square meters. Utility Model Content

[0038] The push rod 101 includes a propulsion end and a free end exposed outside the tool body 1. A clamping area 5 for receiving a cable socket is formed between the propulsion end and a stopper 103 provided at the end of the bracket 102.

[0039] The pushing end of the push rod 101 is fixedly connected to a needle withdrawal pipe joint 2 that can cover the outside of the terminal, and the stopper 103 of the bracket 102 is fixedly connected to a positioning block 3 that can engage with the cable socket;

[0040] During use, the cable socket with the terminal (pin) to be removed is placed in the clamping area 5 and engaged with the positioning block 3 , and the push rod 101 provides a horizontal thrust to push the cable socket and the needle withdrawal pipe connector 2 to separate.

[0041] See also Figure 3 、 7 As shown:

[0042] Preferably, a positioning hole 301 is formed in the middle of the positioning block 3, and a notch portion 302 communicating with the positioning hole 301 is formed on the side of the positioning block 3. The diameter of the positioning hole 301 is larger than the outer diameter of the terminal and smaller than the diameter of the cable socket. During assembly, the positioning block 3 contacts the end of the cable socket through the positioning hole 301, thereby engaging with the cable socket and preventing the cable socket from being pushed from the direction of the push rod 101 and being separated from the positioning block 3. During installation, the cable socket can be quickly placed in the positioning hole 301 through the notch portion 302, thereby achieving quick connection.

[0043] See also Figure 2 As shown:

[0044] Preferably, both sides of the positioning block 3 extend toward the bracket 102 , and mounting holes 303 are provided on both sides of the positioning block 3 . The mounting holes are detachably fixedly connected to the block 103 through connectors, which are bolts or pins in the prior art.

[0045] See also Figure 3 、 4 As shown:

[0046] Preferably, a receiving channel 201 is provided at one end of the needle withdrawal connector 2 , and the receiving channel 201 extends along the extension direction of the push rod 101 , and the terminal in the cable socket is covered by the receiving channel 201 .

[0047] join Figure 4 、 6 As shown:

[0048] Preferably, it further includes a base 4, with through holes 402 formed on both sides of the base 4. The base 4 is fixedly connected to the connecting hole formed on the end of the push rod 101 by a connecting piece passing through the through hole 402. The connecting piece is a screw or a hexagon socket bolt in the prior art. When assembled, the connecting piece passes through the through hole 402 on the base 4 and is threadedly connected to the connecting hole on the end of the push rod 101.

[0049] A joint positioning hole 401 is provided in the middle of the base 4 , and is connected to the needle withdrawal tube joint 2 through the joint positioning hole 401 .

[0050] Preferably, the base 4 and the needle withdrawal pipe joint 2 are both made of metal. A magnet is provided at the end of the needle withdrawal pipe joint 2, which is adsorbed on the joint positioning hole 401 by the magnet, making it easy to disassemble.

[0051] See also Figure 5 、 6 As shown, the needle withdrawal pipe connector 2 is located at the end of the base 4 and has a circular raised column 202. The raised column 202 and the connector positioning hole 401 are transitionally matched to avoid radial displacement when the needle withdrawal pipe connector 2 is used, so that the terminal is pushed out of the cable socket with balanced force. Of course, the connector positioning hole 401 can also be a threaded hole, and the raised column 202 has an external thread. The raised column 202 and the connector positioning hole 401 are fixedly connected in the form of a threaded connection.

[0052] In the above technical solution, the utility model provides a large thread needle withdrawal tool;

[0053] Directions:

[0054] First, assemble the tool by connecting the base 4 to the needle withdrawal pipe joint 2. Then, use the connector to install the assembled base 4 and needle withdrawal pipe joint 2 to the push rod 101 of the tool main body 1. Finally, install the positioning block 3 to the stopper 103 of the bracket 102 of the tool main body 1 through the connector.

[0055] During the needle withdrawal operation: place the assembled cable socket in the clamping area 5, that is, insert it between the positioning block 3 and the needle withdrawal pipe connector 2, confirm that the cable and the metal connector, and the metal connector and the socket are loose, wrap the needle withdrawal pipe connector 2 around the terminal in the socket, and then operate the switch of the tool host 1 to make the needle withdrawal pipe connector 2 move forward with the push rod 101, enter the cable socket and push the terminal in the cable socket at a uniform speed, and finally successfully separate the terminal from the socket.

[0056] The large-wire needle extraction tool effectively solves the problem that after the terminals of cables larger than 10 square meters are installed on the socket, the force applied is large and the manual needle extraction tool cannot be used for extraction. Moreover, the terminals are unevenly stressed and both the terminals and the socket are easily damaged when brute force is used to extract the terminals. The needle extraction tool utilizes the tool main body in combination with the positioning block 3 and the needle extraction pipe joint 2, and uses the push rod 101 to provide electric thrust to realize electric needle extraction, so that the socket is subjected to uniform force when the terminal is withdrawn, thereby achieving the effect of socket reuse.
