[0035] like Figure 2 As shown, the multi-core cable 2 includes a protective layer 21 and a plurality of inner cores 22, wherein the protective layer 21 has an inner cavity, and the plurality of inner cores 22 are arranged in the inner cavity, and the cavity wall of the inner cavity and the plurality of inner cores 22 form a glue-filled gap 2a. Due to the existence of the glue-filled gap 2a, the interior of the multi-core cable 2 cannot be sealed. When such a multi-core cable 2 is applied to equipment with high sealing requirements, it will undoubtedly bring huge risks, and outside air can enter the equipment through the glue-filled gap 2a inside the cable, affecting the sealing and insulation of the equipment.

[0036] The present application provides a glue filling device 1, which can allow sealant 4 to fill the glue filling gap 2a inside the cable, so that the multi-core cable 2 can achieve a completely sealed effect. The present application can achieve the purpose of mechanized glue filling for the multi-core cable 2, and the glue filling device 1 provided by the present application has a simple structure.

[0037] Figure 1A glue pouring device 1 provided in an embodiment of the present application is shown, the glue pouring device 1 comprises a glue pouring cylinder 11 and a pressurizing device, the glue pouring cylinder 11 is provided with a receiving chamber 11a, the receiving chamber 11a is used to receive the sealant 4; the glue pouring cylinder 11 is provided with a wiring port 11b and an air port 11c communicated with the receiving chamber 11a; the wiring port 11b is used to pass the multi-core cable 2; the pressurizing device is detachably connected to the glue pouring cylinder 11 and is connected to the air port 11c; Figure 1 As shown, a pressure joint 15 is provided at the air interface 11c of the glue filling cylinder 11, and is connected to the air pipe of the pressurizing device through the pressure joint 15. The pressure joint 15 and the glue filling cylinder 11 are detachably connected. In one embodiment, the pressure joint 15 and the glue filling cylinder 11 are threadedly connected to facilitate disassembly and assembly.

[0038] The pressurizing device inputs compressed air into the accommodating cavity 11a through the air interface 11c to squeeze the sealant 4 in the accommodating cavity 11a into the glue-filling gap 2a of the multi-core cable 2. In this embodiment, the sealant 4 fills the glue-filling gap 2a inside the cable by pressurizing, so that the multi-core cable 2 is completely sealed, the operation is simple, and the glue-filling effect is good.

[0039] The glue filling device 1 provided in the embodiment of the present application includes a glue filling cylinder 11 and a pressurizing device. The accommodating chamber 11a of the glue filling cylinder 11 is filled with sealant 4. When the multi-core cable 2 needs to be filled with sealant 4, the multi-core cable 2 is inserted into the wiring port 11b, and then compressed air is input into the accommodating chamber 11a through the pressurizing device. The sealant 4 is squeezed into the glue filling gap 2a of the multi-core cable 2 under the action of pressure, thereby achieving the purpose of filling the multi-core cable 2 with sealant 4.

[0040] In actual use, first insert one end of the multi-core cable 2 into the wiring port 11b, then pour the prepared sealant 4 into the accommodating chamber 11a, seal the glue-filling cylinder 11, and then connect the air pipe of the pressurizing device and introduce compressed air into the accommodating chamber 11a. In one embodiment, compressed air of about 0.6Mpa can be introduced. When the sealant 4 flows out from the other end of the multi-core cable 2, it means that the cable is sealed, and then the sealant 4 is solidified.

[0041] In this embodiment, the sealant 4 can be made of a two-component silicone gel. When the sealant is not solidified, the viscosity is low and the fluidity is good, so it is easy to perform potting treatment. After solidification, the sealant is soft and elastic, and does not affect the bending and use of the multi-core cable 2. The length of the potted multi-core cable 2 is affected by the fluidity and solidification time of the sealant 4. The better the fluidity of the sealant 4 and the longer the solidification time, the longer the potting length of the multi-core cable 2. In one embodiment, the potting length can exceed 10 meters.

[0042] The multi-core cable 2 encapsulated by the glue encapsulation device 1 provided in the embodiment of the present application has a good sealing effect and will not affect the use of the multi-core cable 2 itself. For equipment with strict sealing requirements and external cables, the multi-core cable 2 is first sealed and encapsulated with glue before use, which undoubtedly greatly enhances the sealing and reliability of the equipment.

[0043] like Figure 1 As shown, in the technical solution of this embodiment, the glue filling device 1 also includes a cable connector 3, which is detachably connected to the glue filling cylinder 11 and connected to the wiring port 11b. The cable connector 3 is used to seal and fix the multi-core cable 2 to the glue filling cylinder 11.

[0044] It is understandable that the cable connector 3 can be used to fix the multi-core cable 2 and the glue-filling cylinder 11 to prevent the multi-core cable 2 from falling off. The cable connector 3 has high sealing performance, which can improve the sealing performance of the glue-filling cylinder 11 during the glue-filling process and improve the glue-filling effect.

[0045] like Figure 1 As shown, in the technical solution of this embodiment, the connection port 11b is located at the lower part of the peripheral wall of the glue-filling cylinder 11. In this way, the sealant 4 in the accommodating cavity 11a can be more smoothly poured into the glue-filling gap 2a of the multi-core cable 2.

[0046] like Figure 1 As shown, in the technical solution of this embodiment, the air interface 11c is located on the top wall of the glue-filling cylinder 11. In this way, compressed air can be smoothly input into the space of the accommodating chamber 11a located above the sealing chamber, ensuring the purpose of pressurizing the accommodating chamber 11a.

[0047] In some embodiments, if the pressure in the accommodation chamber 11a is too high, it may cause safety hazards. To solve the problem of excessive pressure in the accommodation chamber 11a causing unsafe conditions, Figure 1 As shown, in the technical solution of this embodiment, the glue-filling cylinder 11 is further provided with an overflow port communicating with the accommodating chamber 11 a , and an overflow valve 12 is provided at the overflow port.

[0048] It is understandable that a pressure sensor may be provided in the accommodating chamber 11a, and the pressure sensor is connected to the relief valve 12. When the pressure sensor detects that the pressure in the accommodating chamber 11a exceeds a preset threshold, the relief valve 12 is controlled to open to achieve the purpose of pressure relief and improve safety performance. Figure 1 As shown, in this embodiment, the overflow port is located at the lower part of the peripheral wall of the glue filling cylinder 11 and is spaced apart from the wiring port 11b. When the pressure of the accommodating chamber 11a exceeds a preset threshold, the overflow valve 12 is controlled to open, and the sealant 4 flows out from the overflow port, thereby achieving the purpose of pressure relief.

[0049] like Figure 1 As shown, in the technical solution of this embodiment, the glue-filling cylinder 11 includes a cylinder body 111 and a pressure cap 112, and the cylinder body 111 is provided with the wiring port 11b; the pressure cap 112 is detachably connected to the top of the cylinder body 111, and encloses the cylinder body 111 to form the accommodating chamber 11a; the pressure cap 112 is provided with the air interface 11c. In this embodiment, the pressure cap 112 is connected to the cylinder body 111 by bolts. It can be understood that the detachable connection between the pressure cap 112 and the cylinder body 111 can facilitate the operation of injecting the sealant 4 into the accommodating chamber 11a. It only needs to open the pressure cap 112 to inject the sealant 4 into the accommodating chamber 11a. After the pork sealant 4 is completed, the pressure cap 112 is covered on the cylinder body 111 to achieve the purpose of sealing the accommodating chamber 11a.

[0050] like Figure 1 As shown, in the technical solution of this embodiment, a sealing ring 13 is provided between the gland 112 and the cylinder body 111. Thus, the sealing performance between the gland 112 and the cylinder body 111 can be improved by providing the sealing ring 13.

[0051] like Figure 1 As shown, in the technical solution of this embodiment, a sealing portion 1121 is convexly provided on the side of the gland 112 facing the accommodating cavity 11a, and the sealing portion 1121 extends into the accommodating cavity 11a. It can be understood that the sealing portion 1121 is convexly provided on the gland 112 and correspondingly inserted into the accommodating cavity 11a, so that the gland 112 and the cylinder body 111 can be quickly positioned and matched. The peripheral wall of the sealing portion 1121 is provided with an annular groove, and the sealing ring 13 is arranged in the annular groove, and the annular groove provides an installation position for the sealing ring 13.

[0052] In some embodiments, due to the existence of the filling gap of the multi-core cable 2, at the wiring port 11b, when the multi-core cable 2 is locked by the cable connector 3, the filling gap 2a will be compressed and reduced, and the process of the sealant 4 flowing from the accommodating cavity 11a to the filling gap 2a will be hindered to a certain extent, and it may even cause the filling gap 2a to be unable to be completely filled. In order to solve the above technical problems, as Figure 2As shown, in the technical solution of this embodiment, an auxiliary pin 14 is also included. The auxiliary pin 14 is made of metal and has a hollow structure. The auxiliary pin 14 is used to insert into the glue-filled gap 2a before the multi-core cable 2 is inserted into the wiring port 11b. It can be understood that in actual use, the auxiliary pin 14 is first inserted into the end of the multi-core cable 2 to be inserted into the wiring port 11b, and then inserted into the wiring port 11b and locked with the cable connector 3. At this time, since the auxiliary pin 14 is made of metal and has a certain hardness, it can play a supporting role, and since the auxiliary pin 14 is a hollow structure, it can ensure the smooth flow of the sealant 4.
