[0029] Embodiment 1

[0030] like Figure 1 As shown, the embodiment of the utility model provides an integrated cable for ultraviolet curing equipment, including a cable body 1 and two connectors respectively fixed at both ends of the cable body 1. The two connectors of the integrated cable are respectively connected to the lamp head and the system controller in the ultraviolet curing equipment to facilitate the transmission of power and communication signals between the two. In this embodiment, both connectors are male plugs 2, and correspondingly, the lamp head and the system controller in the ultraviolet curing equipment are both equipped with a female socket 3 used in conjunction with the male plug 2.

[0031] The cable body 1 includes a plurality of core wires, including a high-voltage core wire, a low-voltage core wire and a communication core wire.

[0032] like Figure 2As shown, there are two high-voltage core wires, including high-voltage wire A1 and high-voltage wire A2 for connecting the negative pole of the power supply. The high-voltage core wire also includes a high-voltage ground wire B. The high-voltage ground wire is used to connect the positive pole of the power supply. The high-voltage core wire is used to transmit, for example, 5KV (or 15KV, the specific transmission voltage is determined according to the input voltage of the UV curing system). The high-voltage wire A1, the high-voltage wire A2 and the high-voltage ground wire are arranged side by side, and then the outside of the three are wrapped and wound with Mylar 12, tinned copper winding net 15 and non-woven fabric 16 in turn to form a high-voltage sub-cable. In this way, while ensuring high insulation, high withstand voltage and leakage prevention, the uniform winding of the tinned copper winding net and the non-woven fabric can also better shield the mutual interference with other single-core wires.

[0033] There are four communication core wires, namely communication wires D1, D2, D3 and D4, which are used to transmit control signals and feedback signals between the lamp holder and the system controller. Every two communication core wires are tightly twisted to form a twisted pair. A ground wire is added during the twisting. Then the outside of the twisted pair is wrapped with Mylar 12 and aluminum foil 11 in turn to form a communication sub-cable. There are two communication sub-cables in total. In this way, while stably transmitting signals, the transmission and feedback of signals are better guaranteed by adding the aluminum foil 11 wrapping, so as to achieve the effect of being free from external radiation, static electricity and electromagnetic interference.

[0034] There are six low-voltage core wires, namely low-voltage wires C1, C2, C3, C4, C5 and C6. The six low-voltage core wires, two communication sub-cables and two ground wires 13 are evenly arranged around the above-mentioned high-voltage sub-cables, and then wrapped with non-woven fabric 16, inner sheath 14 and outer sheath 17 in turn on the outside to form a cable body 1. In this way, the three-layer protective wrapping structure formed by the non-woven fabric 16, inner sheath 14 and outer sheath 17 ensures the elongation and tensile strength of the cable body 1, improves the flame retardancy and bending rate of the cable body 1, prevents aging and wear of the cable body 1, and effectively increases the service life of the cable body 1.

[0035] like Figure 3-5 As shown, the male plug 2 includes a plug shell 21 and a plug rubber core 22 fixed in the plug shell 21, for example, the plug rubber core 22 is fixed in the plug shell 21 by adhesive; or a guide groove is provided on one of the outer wall of the plug rubber core 22 and the inner wall of the plug shell 21, and a guide ridge used in conjunction is provided on the other, so as to prevent the plug rubber core 22 and the plug shell 21 from rotating relative to each other, and then two locking rings are screwed in the plug shell 21 along the axial direction, and the two locking rings respectively limit the axial position of the plug rubber core 22 from the two sides, so as to achieve the relative position fixation of the plug rubber core 22 and the plug shell 21. Similarly, the female socket 3 equipped in the UV curing device also includes a socket shell 31 and a socket rubber core 32 fixed in the socket shell 31, and the socket rubber core 32 is fixed to the socket shell 31 in the same way as the male plug 2.

[0036] The plug rubber core 22 of the male plug 2 is provided with 13 PIN needles 4, and the arrangement of the 13 PIN needles 4 in the plug rubber core 22 is the same as the arrangement of the 13 core wires in the cable body 1, so that the 13 core wires can be easily connected with each PIN needle 4 in the plug rubber core 22. Correspondingly, for the female socket 3 equipped in the UV curing device, its socket rubber core 32 is also provided with 13 PIN needles 4, and the arrangement is the same as that of the male plug 2. In addition, the portion of the cable body 1 inserted into the plug shell 21 is pressed and fixed to the plug shell 21 by a cable clamp, and each single core wire inside the cable body 1 is respectively connected to the PIN needle 4 in the plug rubber core 22, and high-pressure resistant potting glue is injected into the plug shell 21 to fix each single core wire.

[0037] In this embodiment, 13 grooves corresponding to the PIN pins 4 are arranged on the end surface of the plug rubber core 21 of the male plug 2, that is, on the end surface of the end of the plug rubber core 21 for docking, each position where the PIN pin 4 is arranged is provided with a concentrically arranged groove 23. Correspondingly, 13 protrusions 33 corresponding to the PIN pins 4 are arranged on the end surface of the socket rubber core 31. In this way, after the male plug 2 is docked with the female socket 3, the arc distance between each pair of PIN pins 4 used in conjunction with each other can be increased, thereby better ensuring the pressure resistance effect of the cable body 1.

[0038] In this embodiment, a tinned copper winding net 15 and an aluminum foil 11 are arranged between the inner sheath and the outer sheath in sequence. Except for the high-voltage ground wire B, all the ground wires 13 are connected to the tinned copper winding net 15. In addition, shielding parts made of metal materials, such as a shielding ring 5, are fixed in the shells of the two plugs (i.e., the plug shell 21). The shielding ring 5 is connected to the tinned copper winding net 15, so that each ground wire is connected to the plug through the tinned copper winding net 15 and the shielding ring 5 in sequence, and then grounded through the ultraviolet curing equipment. In this way, while ensuring safe grounding, the interference signal can be directly introduced into the ground. In addition, by adding the aluminum foil 11 and the tinned copper winding net 15 between the inner sheath 14 and the outer sheath 17, the shielding effect can be greatly enhanced. Among them, the ground wire plays a drainage role, ensuring the continuity of the entire shielding body of the cable body 1, and can discharge the induced current generated by the shielding body in the first time to avoid the accumulation of charges to generate an electric field; in addition, the ground wire also has the function of facilitating processing and wiring and reducing shielding resistance.

[0039] The use process of the integrated cable for ultraviolet curing equipment provided by the embodiment of the utility model is as follows:

[0040] The male plugs 2 arranged at both ends of the cable body 1 are respectively connected to the female sockets 3 configured on the lamp head and the system controller of the UV curing equipment. At this time, a connection pair of the male plug 2 and the female socket 3 that cooperate with each other will be formed at the connection between the integrated cable and the lamp head and at the connection between the integrated cable and the system controller. Then, high voltage, low voltage and communication signals can be transmitted between the lamp head and the system controller through each PIN pin 4.

[0041] It is easy to understand that in other preferred embodiments, the two plugs on the integrated cable can also be female sockets 3, and correspondingly, the lamp holder and the system controller in the UV curing device are equipped with male plugs 2. Alternatively, the two plugs on the integrated cable can also be male plugs 2 and female sockets 3, respectively, and correspondingly, one of the lamp holder and the system controller in the UV curing device is equipped with male plugs 2 and the other is equipped with female sockets 3.

[0042] Embodiment 2

[0043] Based on the first embodiment, Figure 3-5 As shown, in this embodiment, further at the butt end of the female socket 3, a plug-in groove 34 is configured between the socket shell 31 and the socket rubber core 32, for example, an annular step is provided on the outer wall of the socket rubber core 32, and the annular step and the inner wall of the socket shell 31 together constitute the above-mentioned plug-in groove 34; of course, an annular step can also be provided on the inner wall of the female socket 3, so that the annular step and the outer wall of the socket rubber core 32 together constitute the plug-in groove 34. Correspondingly, at the butt end of the male plug 2, a socket shell 21 is configured with a plug-in portion 24 protruding from the plug rubber core 22, and the plug-in portion 24 is adapted to the plug-in groove 34.

[0044] Among them, a positioning protrusion 35 is provided on the plug groove 34 (that is, a positioning protrusion 35 is provided on the inner wall of the socket shell 31), and a positioning groove 25 is correspondingly provided on the outer wall of the plug part 24. The positioning groove 25 is in the shape of a long strip and parallel to the axis of the male plug 2, and the positioning groove 25 extends all the way to the butt end face of the male plug 2, so that when the male plug 2 is matched with the female socket 3, the positioning protrusion 35 can enter the positioning groove 25. It is easy to understand that the positioning groove 25 can be a through hole provided on the plug part 24, that is, through the inner and outer walls of the plug part 24. Of course, the positioning groove 25 can also be a non-through hole provided only on the outer wall of the plug part 24, which does not affect the alignment between the male plug 2 and the female socket 3.

[0045] Such arrangement enables the male plug 2 to be inserted into the female socket 3 in a position-determined manner, thereby avoiding collision of the PIN pin 4, and also enables each core wire to transmit signals between the lamp holder and the system controller in a manner matching its function, thereby avoiding docking errors. Of course, in other preferred embodiments, the male plug 2 and the female socket 3 can also be accurately docked by providing docking marks (such as color marks) on the plug housing 21 and the socket housing 31.

[0046] In addition, it is easy to understand that for the male plug 2 and the female socket 3 used in conjunction with each other, the two are fixed to each other in a detachable fixed connection. Usually, a joint nut 6 is sleeved on the outer side of the plug shell 21, and a limit ring (for example, integrally formed) is also provided on the outer wall of the plug shell 21 to prevent the joint nut 6 from falling off, and an external thread matching the joint nut 6 is correspondingly provided on the outer wall of the socket shell 31. Conversely, the joint nut 6 and the limit ring can also be provided on the socket shell 31, and the external thread can be provided on the plug shell 21, which does not affect the detachable fixed connection between the male plug 2 and the female socket 3.

[0047] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
