Technical Field

[0001] This invention relates to the field of electrical automation technology, and in particular to a wiring device for a mold temperature controller heater. Background Technology

[0002] A mold temperature controller generally refers to a mold temperature control machine. Originally used in the injection mold temperature control industry, mold temperature controllers have become increasingly widespread with the development of the machinery industry. Currently, they are generally classified as water temperature controllers, oil temperature controllers, etc. Existing mold temperature controllers typically use a direct connection between the wire and the terminal block. This wiring method prevents rapid disconnection when a short circuit occurs and the terminal block temperature rises, potentially leading to dangerous situations. Summary of the Invention

[0003] To address the aforementioned shortcomings in the prior art, this invention provides a wiring device for a mold temperature controller heater. The purpose of this invention is to solve the problems that existing mold temperature controller wiring methods typically involve directly connecting the wire to the terminal block. This wiring method cannot quickly disconnect the wire when the temperature rises due to a short circuit in the mold temperature controller, thus causing dangerous situations.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0005] A wiring device for a mold temperature controller heater includes a male plug and a female plug that mates with the male plug. The male plug includes an insulating head, one end of which is provided with a wire, and the end of the insulating head away from the wire is tapered. A conductive ring is provided on the outer side of the insulating head, and the conductive ring is electrically connected to the wire. A limiting groove is provided on the outer side of the insulating head, and the limiting groove is a trapezoidal groove.

[0006] The female plug includes an insulating sleeve, one end of which has a slot, and the outer side of the insulating sleeve has an installation groove. The bottom of the installation groove has a guide groove, and a limiting mechanism is provided inside the installation groove.

The wire two is electrically connected to the conductive ring two.

[0007] Furthermore, the limiting mechanism includes a pressure cap disposed in the mounting groove. The bottom of the outer side of the pressure cap is provided with an annular protrusion. The annular protrusion is located in the guide groove. A thermal expansion cylinder is provided between the annular protrusion and the top of the guide groove. A wedge block one and a wedge block two arranged symmetrically with the wedge block one are provided on the inner wall of the pressure cap. A limiting rod is provided inside the pressure cap. A spring two is provided between the top of the limiting rod and the top of the inner side of the pressure cap. A Z-shaped rod is slidably connected to the limiting rod. The two ends of the Z-shaped rod are respectively in contact with the wedge block one and the wedge block two. The end of the limiting rod away from the spring two is adapted to the limiting groove.

[0008] Furthermore, the thermal expansion cylinder includes a cylinder body fixedly connected to the top of the guide groove, a piston is provided inside the cylinder body, a sealing ring is provided between the piston and the inner wall of the cylinder body, a sealing cavity is formed between the piston and the bottom of the cylinder body, a piston rod is provided at the end of the piston away from the sealing cavity, and the end of the piston rod away from the piston is abutted against an annular protrusion.

[0010] The beneficial effects of this invention are as follows:

[0011] This invention discloses a wiring device for a mold temperature controller heater. It allows for quick wiring via a male and female plug. A limiting mechanism prevents the male plug from detaching. When the mold temperature controller wiring terminal short-circuits and overheats, a thermal expansion cylinder presses down the limiting mechanism, and a spring pushes the male plug outwards, separating conductive coils one and two, thus automatically cutting off power. When the wiring terminal temperature drops, the air in the sealed cavity contracts, and the spring pushes the limiting rod back into the limiting groove, bringing conductive coils one and two into contact, allowing the mold temperature controller to resume normal operation. This effectively prevents dangerous situations caused by overheating of the mold temperature controller wiring terminal. Attached Figure Description

[0019] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0020] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0021] To make the content of this invention easier to understand, the technical solutions in the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings.

[0022] like Figures 1 to 5 As shown, a wiring device for a mold temperature controller heater includes a male plug 1 and a female plug 2 that mates with the male plug 1. Through the male plug 1 and the female plug 2, the male plug 1 is inserted into the slot 22 of the female plug 2, and the first conductive ring 13 and the second conductive ring 26 are in contact, which can quickly connect the wires. The male plug 1 includes an insulating head 11, one end of which is provided with a wire 12. The end of the insulating head 11 away from the wire 12 is tapered. The outer side of the insulating head 11 is provided with a conductive ring 13, which is electrically connected to the wire 12. The outer side of the insulating head 11 is provided with a limiting groove 14, which is a trapezoidal groove.

[0023] The female plug 2 includes an insulating sleeve 21, a slot 22 is provided at one end of the insulating sleeve 21, an installation groove 23 is provided on the outer side of the insulating sleeve 21, a guide groove 24 is provided at the bottom of the installation groove 23, a limiting mechanism 25 is provided in the installation groove 23, a conductive ring 26 is provided on the inner wall of the slot 22, a spring groove 27 is provided at the bottom of the installation groove 23, a spring 28 is provided in the spring groove 27, and a wire 29 is provided at the end of the insulating sleeve 21 away from the slot 22, and the wire 29 is electrically connected to the conductive ring 26.

[0024] The limiting mechanism 25 includes a pressure cap 251 disposed in the mounting groove 23. A ring-shaped protrusion 252 is provided on the bottom of the outer side of the pressure cap 251. The ring-shaped protrusion 252 is located in the guide groove 24. A thermal expansion cylinder 253 is provided between the ring-shaped protrusion 252 and the top of the guide groove 24. A wedge block 1 254 and a wedge block 255 arranged symmetrically with wedge block 1 254 are provided on the inner wall of the pressure cap 251. A limiting rod 256 is provided inside the pressure cap 251. A spring 257 is provided between the top of the limiting rod 256 and the top of the inner side of the pressure cap 251. A Z-shaped rod 258 is slidably connected to the limiting rod 256. The two ends of the Z-shaped rod 258 are respectively in contact with wedge block 1 254 and wedge block 255. The end of the limiting rod 256 away from the spring 257 is adapted to the limiting groove 14.

[0025] The limiting mechanism 25 prevents the male plug 1 from falling off. When it is necessary to disconnect the male plug 1 and the female plug 2, press down the cap 251. The Z-shaped rod 258 slides between the first wedge block 254 and the second wedge block 255. The Z-shaped rod 258 lifts the limiting rod 256, which can disconnect the male plug 1 and the female plug 2.

[0026] The thermal expansion cylinder 253 includes a cylinder body 2531 fixedly connected to the top of the guide groove 24. A piston 2532 is provided inside the cylinder body 2531. A sealing ring 2533 is provided between the piston 2532 and the inner wall of the cylinder body 2531. A sealing cavity is formed between the piston 2532 and the bottom of the cylinder body 2531. A piston rod 2534 is provided at the end of the piston 2532 away from the sealing cavity. The end of the piston rod 2534 away from the piston 2532 is set to abut against the annular protrusion 252.

[0027] The widths of conductive coil 13 and conductive coil 26 are equal. The width of conductive coil 13 is less than the width of spring 28 extending out of spring groove 27. The width of spring 28 extending out of spring groove 27 is less than the horizontal width of trapezoidal inclined surface of limiting groove 14. The stroke of thermal expansion cylinder 253 is less than the vertical height of limiting groove 14. The vertical height of limiting groove 14 is less than the horizontal width of trapezoidal inclined surface of limiting groove 14.

[0028] When the mold temperature controller terminal short-circuit and heats up, the air in the sealed cavity expands due to heat through the thermal expansion cylinder 253. The piston 2532 drives the piston rod 2534 to press down the pressure cap 251. The Z-shaped rod 258 slides between the first wedge block 254 and the second wedge block 255. The Z-shaped rod 258 lifts the limit rod 256, and the first spring 28 pops the male plug 1 outward. The first conductive ring 13 and the second conductive ring 26 disengage, thereby achieving automatic power-off. Since the width of the first conductive ring 13 is less than the width of the first spring 28 extending out of the spring groove 27, the width of the first spring 28 extending out of the spring groove 27... The stroke of the thermal expansion cylinder 253 is less than the vertical height of the limiting groove 14, and the vertical height of the limiting groove 14 is less than the horizontal width of the trapezoidal inclined surface of the limiting groove 14. Therefore, the spring 1 28 will not push the male plug 1 out of the slot 22. When the temperature of the terminal drops, the air in the sealed cavity contracts, and the spring 257 pushes the limiting rod 256 back into the limiting groove 14. The conductive ring 13 and the conductive ring 26 come into contact, and the mold temperature controller starts to work normally, effectively avoiding the occurrence of dangerous situations caused by the overheating of the mold temperature controller terminal.

[0029] The present invention discloses a wiring device for a mold temperature controller heater. A male plug 1 and a female plug 2 are provided for quick wiring. A limiting mechanism 25 prevents the male plug 1 from detaching. When the mold temperature controller wiring terminal short-circuits and overheats, a thermal expansion cylinder 253 presses down the limiting mechanism 25, and a spring 28 ejects the male plug 1 outwards, causing conductive coils 13 and 26 to disengage, thus achieving automatic power-off. When the wiring terminal temperature drops, the air in the sealed cavity contracts, and a spring 257 pushes the limiting rod back into the limiting groove 14, bringing conductive coils 13 and 26 into contact. The mold temperature controller then resumes normal operation, effectively preventing dangerous situations caused by overheating of the mold temperature controller wiring terminal.

[0030] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
