[0002] Hot runner heaters are industrial heating devices mainly used for metal heat treatment, fuel oil pretreatment, and constant temperature heating of injection molds. They work by means of electromagnetic induction or resistance wire heating, using alternating magnetic fields to induce eddy currents inside the metal or to directly generate heat, which can reduce the viscosity of fuel oil and maintain the temperature stability of plastic runners.

[0003] Most existing hot runner heating elements lack quick-connect devices, making the connection process complex. In production scenarios requiring rapid mold changes or high-speed cycles, this can significantly impact worker efficiency, thereby reducing production efficiency and making the elements inconvenient for workers to use. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick connection device for hot runner heating elements, which solves the problem mentioned in the background that most existing hot runner heating elements lack quick connection devices, making the connection of heating elements complex. In production scenarios requiring rapid mold changes or high-speed cycles, this can significantly impact the work efficiency of staff, thereby reducing production efficiency and making the devices inconvenient for staff to use.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quick connection device for a hot runner heating element, comprising a terminal block, a power supply wire 1 fixedly connected to the left end of the terminal block, a foolproof indicator mark fixedly connected to the surface of the terminal block, a mounting slot formed on the upper surface of the terminal block, a plug-in slot formed inside the terminal block, a power supply terminal fixedly connected inside the plug-in slot, a plug connector inserted into the plug-in slot, a connector fixedly connected to the right end of the plug connector, a limit block fixedly connected to the left end of the connector, an arc-shaped locking head fixedly connected to the left end of the limit block, a reinforcing rib fixedly connected to the top right end of the limit block, a second power supply wire fixedly connected to the right end of the connector, and an electric heating coil fixedly connected to the right end of the second power supply wire. Preferably, there are two mounting slots, which are symmetrically distributed on the upper and lower surfaces of the terminal block.

[0006] Preferably, there are two limiting blocks, which are symmetrically distributed on the upper and lower sides of the connector. The positions of the two limiting blocks correspond to the positions of the two mounting slots, and the two limiting blocks are in close contact with the two mounting slots.

[0007] By adopting the above technical solution, a limit block and an installation slot are used in conjunction with an arc-shaped locking head. When the limit block is inserted into the installation slot, the arc-shaped locking head will slightly lift the limit block. When the limit block is fully inserted into the installation slot, the arc-shaped locking head will move to the left end of the connector and lock onto the connector, thereby locking the position of the connector and preventing poor contact caused by connector shaking, thus facilitating use.

[0008] Preferably, the number of power supply terminals is several, and the several power supply terminals are arranged in a linear array inside the plug slot, and the inner wall shape of the plug slot is adapted to the shape of the plug.

[0009] By adopting the above technical solution, power supply terminals, plug slots, and connectors are used in conjunction. The connector is inserted into the plug slot and comes into contact with the power supply terminal. The limit block will also lock it on the terminal, thus completing the connection. At the same time, the number and position of the power supply terminals are the same, so they can be quickly connected regardless of whether the connector is inserted in the right or wrong direction, which improves efficiency and makes it convenient for personnel to use.

[0010] Preferably, there are two arc-shaped clips, which are symmetrically distributed on one side of the two limiting blocks that are close to each other, and the side of the two arc-shaped clips that is close to the connector has a vertical cross section.

[0011] Preferably, there are two reinforcing ribs, and the two reinforcing ribs are respectively located on the right end surface of the two limiting blocks.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The quick connection device for the hot runner heating element is designed with power supply terminals, plug slots, and connectors. The connector is inserted into the plug slot and makes contact with the power supply terminal. The limit block will also lock the connector onto the terminal to complete the connection. Since the number and position of the power supply terminals are the same, the connectors can be quickly connected regardless of whether they are inserted in the correct orientation, which improves efficiency and makes it convenient for users.

[0013] 2. The quick-connect device for this hot runner heating element uses a limit block, a mounting slot, and an arc-shaped clamp head. When the limit block is inserted into the mounting slot, the arc-shaped clamp head will slightly lift the limit block. When the limit block is fully inserted into the mounting slot, the arc-shaped clamp head will move to the left end of the connector and lock onto the connector, thus locking the position of the connector and preventing poor contact caused by connector movement, making it convenient to use.

A power supply wire 2 is fixedly connected to the left end of the terminal block 1. A foolproof indicator 3 is fixedly connected to the surface of the terminal block 1. Two mounting slots 4 are symmetrically distributed on the upper and lower surfaces of the terminal block 1. A plug-in groove 5 is provided inside the terminal block 1. A power supply terminal 6 is fixedly connected inside the plug-in groove 5. A connector 7 is inserted into the plug-in groove 5. Several power supply terminals 6 are provided. Electrical terminals 6 are arranged in a linear array inside the plug slot 5, and the inner wall shape of the plug slot 5 is adapted to the shape of the plug 7. A connector 8 is fixedly connected to the right end of the plug 7, and a limit block 9 is fixedly connected to the left end of the connector 8. An arc-shaped locking head 11 is fixedly connected to the left end of the limit block 9. A reinforcing rib 10 is fixedly connected to the top right end of the limit block 9. There are two reinforcing ribs 10, and the two reinforcing ribs 10 are located on the right end surfaces of the two limit blocks 9 respectively. A second power supply line 12 is fixedly connected to the right end of the connector 8, and an electric heating coil 13 is fixedly connected to the right end of the second power supply line 12.

[0018] Working principle: When in use, if the operator needs to quickly connect the heating element, they only need to move the connector 7 through the connector head 8 and align it with the insertion slot 5 inside the terminal head 1. When the connector 7 is inserted into the insertion slot 5, it will automatically contact the power supply terminal 6. The limit block 9 will also lock it on the terminal head 1, thus completing the connection. At the same time, the number and position of the power supply terminals 6 are the same, so they can be quickly connected regardless of whether the connector 7 is inserted in the right or wrong direction, avoiding the possibility of operator misoperation. At this time, the electric heating coil 13 can be powered through the power supply line 12 and the power supply line 212. The operation is simple, greatly improving work efficiency and making it convenient for personnel to use.

[0019] Compared with related technologies, the quick connection device for hot runner heating elements provided by this utility model has the following advantages: by setting power supply terminals 6, plug slots 5, plug connectors 7 and so on, the plug connector 7 is inserted into the plug slot 5 and contacts the power supply terminal 6. The limiting block 9 will also lock it on the wiring terminal 1, thus completing the connection. At the same time, the number and position of the power supply terminals 6 are the same, so the plug connector 7 can be quickly connected regardless of whether it is inserted in the right or wrong direction, which improves efficiency and facilitates personnel use.

[0020] Example 2: Referring to Figures 1-6, the upper surface of the terminal 1 has a mounting slot 4, and the inside of the terminal 1 has a plug slot 5. A power supply terminal 6 is fixedly connected inside the plug slot 5, and a plug connector 7 is plugged into the plug slot 5. A connector head 8 is fixedly connected to the right end of the plug connector 7, and a limit block 9 is fixedly connected to the left end of the connector head 8. There are two limit blocks 9, which are symmetrically distributed on the upper and lower sides of the connector head 8.

An arc-shaped clip head 11 is fixedly connected to the left end of the limit block 9, and a reinforcing rib 10 is fixedly connected to the top right end of the limit block 9.

[0021] Working principle: When the connector 7 is inserted into the connector slot 5, the connector 8 will also drive the limit block 9 to be inserted into the corresponding mounting slot 4. At this time, the arc-shaped locking head 11 will slightly lift the limit block 9. When the limit block 9 is fully inserted into the mounting slot 4, the arc-shaped locking head 11 will move to the left end of the terminal 1 and lock onto the terminal 1, thereby locking the position of the connector 8 and preventing the connector 8 from shaking and causing poor contact, making it convenient to use.

[0022] Compared with related technologies, the quick connection device for a hot runner heating element provided by this utility model has the following advantages: by setting a limiting block 9, a mounting slot 4, etc., in conjunction with an arc-shaped locking head 11, when the limiting block 9 is inserted into the mounting slot 4, the arc-shaped locking head 11 will slightly lift the limiting block 9. When the limiting block 9 is fully inserted into the mounting slot 4, the arc-shaped locking head 11 will move to the left end of the terminal 1 and engage with the terminal 1, thereby locking the position of the connector 8 and preventing the connector 8 from shaking and causing poor contact, which is convenient to use.
