[0002] Silicone wire (also known as silicone cable) is a common conductive part. It can be used in a long-term humid environment. It has excellent electrical performance and waterproof and mildew-proof properties. It has excellent bending performance, and the minimum bending radius is 16 times the outer diameter of the cable. It can be used in mobile applications. It is used in various mobile motors, steel, aviation, power plants, petrochemicals and other high-temperature environments with an AC rated voltage of 300 / 500V and below.

[0003] The end of the silicone wire needs to be provided with a connector, which is used to connect the silicone wire to the current or signal receiving part of the device. The connector is generally made of metal to have a good conductive effect.

[0004] In general connection technology, the connector is mainly put on the conductor, and then the connector is squeezed and deformed by stamping equipment so that the connector can clamp the conductor. However, the silicone wire and connector stamped by ordinary equipment have a small stamping contact area and are prone to loosening after long-term use or bending and twisting, affecting subsequent safety.

[0033] The following is combined with Figure 1 -Attached Fig.10 , further details of this application are given.

[0034] The embodiments of the present application disclose a silicone wire metal joint structure and a crimping machine.

[0035] A silicone wire metal joint structure 1, reference Figure 1 As shown, it includes a silicone wire 11, a fastener 12 and a fastening insulating layer 13; the surface of the silicone wire 11 is wrapped with a silicone insulating layer 112, and a metal inner core 111 is exposed at one end; the fastener 12 is made of metal, the fastening insulating layer 13 is wrapped around the fastener 12, and the fastening insulating layer 13 is cylindrical after being wrapped, and the interior is a connecting cavity. The fastener 12 can be a metal terminal, which is connected to a circuit board or circuit device of other equipment through the fastener 12. The cylindrical inner diameter of the fastening insulating layer 13 is greater than or equal to the diameter of the silicone insulating layer 112, so that it can be plugged with the silicone insulating layer 112 and the metal inner core 111.

[0036] The fastener 12 is sleeved on the silicone wire 11 through the fastening insulating layer 13, so that the silicone wire 11 is plugged into the fastening insulating layer 13, and the fastener 12 is in contact with the metal inner core 111, and the metal inner core 111 and part of the silicone insulating layer 112 are both located in the connecting cavity. The plugged silicone wire 11 and the fastener 12 are then placed on a crimping machine 2 and crimped into shape by the crimping machine 2.

[0037] After crimping, the fastening insulating layer 13 at the connection between the metal inner core 111 and the fastener 12 is crimped into a hexagonal column shape, and the fastening insulating layer 13 and the silicone insulating layer 112 are wrapped into a cylindrical joint structure 1.

[0038] The diameter of the metal inner core 111 is smaller than the outer diameter of the silicone insulating layer 112. When the fastening insulating layer 13 is crimped into a hexagonal column by the crimping machine 2, the metal inner core 111 is wrapped in the hexagonal columnar fastening insulating layer 13. The metal inner core 111 is wrapped and pressed by the hexagonal columnar structure. The hexagonal columnar structure can increase the pressing area between the metal inner core 111 and the fastening insulating layer 13, thereby increasing the stability of the crimping between the fastener 12 and the silicone wire 11. The fastening insulating layer 13 and the silicone insulating layer 112 are partially cylindrical, so that the two insulating layers are overlapped to increase the insulation effect. When the user takes or removes the electrical connection of the silicone wire 11, the use of two layers of insulating layers can increase safety.

[0039] For further reference, Figure 1 As shown, after the fastening insulating layer 13 is crimped, an annular fastening groove 131 is crimped to form the covering silicone insulating layer 112. The fastening groove 131 formed by crimping allows the silicone insulating layer 112 to be simultaneously pressed into the fastening groove 131, that is, the fastening groove 131 simultaneously applies pressure to the silicone insulating layer 112, so that the silicone insulating layer 112 is simultaneously pressed out of the groove, so that both insulating layers are located in the annular groove, and the limiting effect provided by the fastening groove 131 pressing on the silicone insulating layer 112 is used to increase the stability of the connection between the silicone insulating layer 112 and the fastening insulating layer 13.

[0040] Further, refer to Figure 1 As shown, a plurality of fastening grooves 131 are provided, so that the silicone insulating layer 112 is fixed by a plurality of crimped fastening grooves 131 , thereby increasing the pressing area and further improving the stability of the connection between the silicone insulating layer 112 and the fastening insulating layer 13 .

The first crimping piece 24 can abut against the upper half of the joint structure 1, and the second crimping piece 25 abuts against the lower half of the joint structure 1. The driving end of the first crimping piece 24 and the crimping driving piece 221 enables the crimping driving piece 221 to provide a driving force for the first crimping piece 24 to move along the limiting cavity 231. The end of the first crimping piece 24 away from the crimping driving piece 221 abuts against the second crimping piece 25.

The moving direction can be moving toward the second crimping member 25, or moving away from the second crimping member 25. When moving toward the second crimping member 25, the first crimping portion 242, the second crimping portion 243 and the third crimping portion 244, as well as the three crimping portions of the second crimping member 25 are pressed down synchronously, thereby driving the six-sided crimping interface 26 to close synchronously, so as to crimp the fastening insulating layer 13 of the joint structure 1 into a six-sided columnar shape.

[0048] Further, refer to Figure 5 As shown, an extension groove is further provided on the first crimping portion 242 and the second crimping portion 243, and the extension groove is located inside the first crimping portion 242 and the second crimping portion 243, so it is not shown in the figure. A fixing rod 246 is provided in the extension groove, and a clamping block 2461 is provided at one end of the fixing rod 246. A reset portion 247 is wrapped around the surface of the fixing rod 246, one end of the reset portion 247 is connected to the clamping block 2461, and the other end extends into the extension groove and is connected to the groove wall, so that when the crimping drive member 221 drives the sliding plate 241 to slide along the limiting cavity 231, the first crimping portion 242 and the second crimping portion 243 are pressed to move toward the direction of the second crimping member 25, and the fixing rod 246 is inserted into the extension groove synchronously.

[0054] When the crimping drive 221 drives the first crimping member 24 to crimp, the first pressing block 281 is synchronously driven to move toward the second pressing block 282, so that the pressing groove 283 is closed, and the two semicircular pressing rings 284 are respectively pressed against the outer wall of the fastening insulation layer 13 in the vertical direction. When the semicircular pressing rings 284 are continuously subjected to force, the fastening insulation layer 13 is continuously squeezed to press the fastening insulation layer 13 toward the silicone insulation layer 112, so that grooves are formed on the fastening insulation layer 13 and the silicone insulation layer 112, and the grooves are used to limit the connection ends of the silicone insulation layer 112 and the fastening insulation layer 13 to improve the connection stability between the two.

[0055] Further, refer to Figure 8As shown, a plurality of semicircular pressing rings 284 are provided at preset intervals. The figure takes the first pressing block 281 and three semicircular pressing rings 284 as an example, so that when the first pressing block 281 and the second pressing block 282 are pressed together, a plurality of fastening grooves 131 can be pressed together simultaneously, so as to increase the number of fastening grooves 131, increase the number of limit stops, and further improve the connection stability between the silicone insulation layer 112 and the fastening insulation layer 13.

[0056] Furthermore, an elastic spacer 285 is provided between adjacent semicircular pressing rings 284. The elastic spacer 285 can be a semicircular rubber ring. The semicircular rubber ring is filled between the semicircular pressing rings 284, thereby preventing the semicircular pressing rings 284 from being damaged due to uneven force during the pressing process, providing a certain buffering and pressure resistance effect, and ensuring stability during pressing.

[0057] In another embodiment, reference Fig. 9 and Fig.10 As shown, the receiving member 27 is also provided with a positioning ring 272 with a top opening, and the position of the positioning ring 272 is staggered from the first pressing block 281, that is, it is located outside the pressing range of the first pressing block 281, so that when the first pressing block 281 and the second pressing block 282 are fitted together, the first pressing block 281 will not press on the positioning ring 272, and a wedge block 273 is provided at the bottom of the positioning ring 272, and a sliding groove is also provided on the receiving member 27, and the wedge block 273 is slidably connected to the sliding groove.

[0058] The semicircular pressing ring 284 is connected to the first pressing block 281 and the second pressing block 282 in a sliding connection. A limiting groove is provided in the pressing groove 283, and a plurality of protrusions are provided in the semicircular pressing ring 284. The protrusions are inserted into the limiting grooves so that the semicircular pressing ring 284 can be slidably connected along the limiting grooves, and the adjacent semicircular pressing rings 284 are spaced apart by the elastic spacer 285. The limiting grooves and protrusions are not shown in the figure.

[0059] The first pressing block 281 is connected to the lower pressing wheel 274, which contacts the wedge block 273. When the first pressing block 281 is pressed toward the second pressing block 282, the lower pressing wheel 274 contacts the wedge surface of the wedge block 273, so that the wedge block 273 drives the positioning ring 272 to move toward the pressing opening.

[0060] Since the top of the positioning ring 272 is open, the silicone insulating layer 112 and the fastening insulating layer 13 can be embedded in the positioning ring 272 to provide the silicone wire 11 with a positioning and anti-deviation effect. After the pressing is completed, the silicone wire 11 can be pulled out from the opening to separate from the positioning ring 272.

[0061] The inner diameter of the positioning ring 272 is larger than the inner diameter of the pressing opening formed when the first pressing block 281 and the second pressing block 282 are fitted together, so that the positioning ring 272 pushes the semicircular pressing ring 284 during the movement of the wedge block 273, so that the semicircular pressing ring 284 is pushed and moves toward the elastic spacer 285, so that when the fastening groove 131 is formed, the pressing effect between adjacent fastening grooves 131 is tighter, and the semicircular pressing rings 284 are pressed against each other and cooperate with the grooves formed synchronously with the silicone insulation layer 112, so that the connection between the two is more stable.

[0062] Furthermore, a heating source can be set in the first pressing block 281 and the second pressing block 282. The heating source can be a heating wire or a heating tube, which can generate heat. The heat is transferred to the semicircular pressing ring 284, which can temporarily soften part of the insulating layer, making the fastening groove 131 easier to form, and can also cooperate with the pressing of the positioning ring 272 to make the pressing effect more stable. The heating source is located in the first pressing block 281 and the second pressing block 282, so it is not shown in the figure.

[0063] When the heating source is provided, the elastic spacer 285 needs to be made of a high temperature resistant elastic material.

[0064] Furthermore, the wedge block 273 may be connected to a return spring, and the return spring may be disposed in the slide groove to provide a return effect. The slide groove and the return spring are not shown in the figure.

[0065] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
