[0023] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0024] The following is for reference. Figure 1 and Figure 2 This invention describes an extruder terminal block and an extruder according to an embodiment of the present invention.

[0025] like Figure 1 and Figure 2 As shown, the extruder terminal block of this embodiment includes a copper post 1 and a first set screw 2.

[0026] The copper column 1 has a fixed end 11 and a terminal 12. The fixed end 11 is provided with a threaded hole 13. The internal thread of the threaded hole 13 is adapted to the external thread on the terminal of the extruder heating block so that the fixed end 11 is used to connect the terminal. The terminal 12 is provided with a wire hole 14 for inserting a cable. The first set screw 2 passes through the wall of the terminal 12 and can move radially along the copper column 1, thereby squeezing and releasing the cable in the wire hole 14.

[0027] like Figure 1 and Figure 2 As shown, the copper column 1 extends in the left and right direction. The left end of the copper column 1 is the wiring terminal 12, and the right end of the copper column 1 is the fixing terminal 11.

[0028] The fixed end 11 is provided with a threaded hole 13 preferably, but not limited to, arranged in the left-right direction. The inner circumferential surface of the threaded hole 13 is provided with an internal thread. The internal thread of the threaded hole 13 is adapted to the external thread on the terminal of the heating block of the extruder, so that the fixed end 11 can be detachably threadedly connected to the terminal of the heating block through the threaded hole 13.

[0029] Terminal 12 is provided with a through hole 14, preferably but not limited to being arranged in a left-right direction, for inserting a cable. A first set screw 2 passes through the wall of terminal 12 and is movable radially relative to the copper post 1. In other words, the wall of terminal 12 of copper post 1 is provided with a first mounting hole that passes through and communicates with the through hole 14. The first set screw 2 is threadedly connected to the first mounting hole and is movable along the first mounting hole. This allows the first set screw 2 to compress and release the cable in the through hole 14, thereby detachably connecting the cable to terminal 12 via the first set screw 2.

[0030] In this embodiment of the extruder terminal block, the fixed end 11 of the copper pillar 1 is provided with a threaded hole 13 to thread-connect the terminal block of the extruder heating block, so that the copper pillar 1 and the terminal block of the heating block can be quickly and easily detached and connected, while ensuring the connection area and connection stability. The terminal end 12 of the copper pillar 1 is provided with a wire hole 14 and a first set screw 2 to connect the cable, so that the copper pillar 1 and the cable can be quickly and easily detached and connected, while ensuring the connection area and connection stability. Thus, the terminal block of the heating block and the cable are connected and conductive through the copper pillar 1 and the first set screw 2, which has high connection stability and large current carrying capacity.

[0031] In some embodiments, the copper pillar 1 is provided with a through hole that extends axially. The portion of the through hole located at the terminal 12 forms a wire hole 14, and the portion of the through hole located at the fixed end 11 is provided with an internal thread and forms a threaded hole 13.

[0032] like Figure 1 and Figure 2 As shown, the copper pillar 1 has a through hole extending through it in a left-right direction. The left end of the through hole forms a wire hole 14 located at the terminal 12, and the right end of the through hole has an internal thread forming a threaded hole 13 located at the fixed end 11. In other words, the wire hole 14 and the threaded hole 13 extend in the same direction and are connected. This facilitates the connection of the copper pillar 1 between the cable and the terminal of the heating block, making it convenient for users to operate.

[0033] In some embodiments, the outer diameter of the copper column 1 is greater than or equal to 9 mm, such as 9 mm, 10 mm, 12 mm, 15 mm, etc., to ensure the cross-sectional area of ​​the copper column 1, thereby ensuring that the copper column 1 has a high current carrying capacity and a high heat dissipation capacity.

[0034] In some embodiments, the standard diameter of the internal thread of the threaded hole 13 is 4.2mm to 6.0mm, such as 4.2mm, 5.0mm, 6.0mm, etc., preferably 5.0mm. This ensures a stable connection between the heating block's terminals and the fixed end 11, with a large contact area for conductivity, while also ensuring the fixed end 11 has a large cross-sectional area to guarantee high current carrying capacity and high heat dissipation capability.

[0035] In some embodiments, the diameter of the wire hole 14 is 3.4 mm to 5.1 mm, such as 3.4 mm, 3.5 mm, 4.2 mm, 4.8 mm, 5.1 mm, etc., preferably 3.5 mm, to facilitate the insertion of the cable into the wire hole 14.

[0036] In some embodiments, there are at least two first set screws 2, and the at least two first set screws 2 are arranged at axial intervals along the thread hole 14.

[0037] like Figure 1 and Figure 2As shown, the first set screw 2 is preferably, but not limited to, two arranged at intervals in the left-right direction to ensure that the cable in the wire hole 14 is fully squeezed to fix the cable in the wire hole 14 and to ensure the connection stability between the cable and the terminal 12.

[0038] In some embodiments, the center distance between adjacent first set screws 2 is 6mm to 8mm, such as 6mm, 7mm, 8mm, etc. This ensures that adjacent first set screws 2 fully compress the cable without causing mutual interference.

[0039] In some embodiments, the extruder terminal block further includes a second set screw 3, which passes through the wall of the fixed end 11 and can move radially along the copper post 1, thereby squeezing and releasing the terminal block in the threaded hole 13.

[0040] like Figure 1 and Figure 2 As shown, a second setter screw 3 passes through the wall of the fixed end 11, and the second setter screw 3 can move radially relative to the copper pillar 1. In other words, the wall of the fixed end 11 of the copper pillar 1 is provided with a second mounting hole that passes through and communicates with the threaded hole 13. The second setter screw 3 is threadedly connected to the second mounting hole and can move along the second mounting hole. This allows the second setter screw 3 to press and release the terminal in the threaded hole 13, thereby further ensuring a stable connection between the terminal of the heating block and the fixed end 11.

[0041] In some embodiments, the ends of the first set screw 2 and the second set screw 3 facing the axis of the copper pillar 1 are both closed, and the other ends of the first set screw 2 and the second set screw 3 away from the axis of the copper pillar 1 are both provided with internal hexagonal holes 4.

[0042] like Figure 1 and Figure 2 The first set screw 2 and the second set screw 3 preferably extend in a vertical direction, but are not limited to this. The bottom ends of the first set screw 2 and the second set screw 3 are located inside the copper pillar 1, and the top ends of the first set screw 2 and the second set screw 3 are located outside the copper pillar 1. The bottom end of the first set screw 2 is used to squeeze and release the cable, and the bottom end of the second set screw 3 is used to squeeze and release the terminal block. The top ends of the first set screw 2 and the second set screw 3 are provided with hexagonal holes 4, so that the first set screw 2 and the second set screw 3 can be rotated by an hexagonal wrench to adjust the position of the first set screw 2 and the second set screw 3 in the radial direction of the copper pillar 1, thereby realizing the squeezing and releasing action.

[0043] The extruder of this utility model embodiment includes an extrusion pipe, a heating block, extruder terminals, and cables.

[0044] The extruder terminal block is the extruder terminal block of this utility model embodiment. The heating block is located in the extrusion pipe. The heating block has a terminal post. The terminal post has an external thread and fits in the threaded hole 13. One end of the cable is located in the wire hole 14, and the other end of the cable is connected to the power supply device.

[0045] Specifically, a heating block is provided on the outer periphery of the extrusion pipe. The heating block has a protruding terminal post. The terminal post is cylindrical and has an external thread on its outer periphery so that it fits into the threaded hole 13 and is threadedly connected to the fixed end 11 of the copper pillar 1. One end of the cable extends into the wire hole 14 of the terminal 12 of the copper pillar 1, and one end of the cable is pressed and fixed by the first set screw 2. The other end of the cable is connected to a power supply device, thereby supplying power to the heating block through the copper pillar 1 to generate heat.

[0046] The extruder of this utility model embodiment connects the heating block's terminals to the cable through the extruder's wiring terminals, thus achieving high connection stability and a large current carrying capacity.

[0047] Furthermore, the terminal block fits into the threaded hole 13 and is pressed and fixed by the second set screw 3 to ensure a stable connection between the terminal block and the fixed end 11 of the copper post 1.
