[0029] The present invention provides a method and system for producing a connector, and a connector. To make the objectives, technical solutions, and effects of the present invention clearer and more specific, the present invention is further described in detail below with reference to the accompanying drawings and examples.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and should not be understood as limitations on the present invention. In addition, the terms "installation", "connection", etc. should be understood in a broad sense. For ordinary technicians in this field, they can understand the specific meanings of the above terms in the present invention according to specific circumstances.

[0031] See also Figure 1 The present invention provides a method for producing a connector, comprising the following steps:

[0032] 101. Remove at least a portion of the outer insulation layer on the electric wire, and remove at least a portion of the outer insulation layer on the copper wire;

[0033] 102. Apply sealant to the copper wire in the copper wire;

[0034] 103. Place at least part of the wire with the outer insulation layer removed into a fixture, and fix the copper wire in the packaging cavity of the fixture;

[0035] 104. Inject glue into the packaging cavity and vibrate the fixture so that the copper wire and the electric wire are wrapped in the packaging cavity by the glue;

[0036] 105. Cooling the fixture to obtain the connector.

[0037] In actual application, at least part of the outer insulating layer on the electric wire is removed, and at least part of the outer insulating layer on the copper wire is removed, sealant is applied to the copper wire in the copper wire, the sealant is allowed to penetrate into the gaps between the copper wires, and the gaps between the copper wires are sealed. The copper wire is fixed through the packaging cavity of the fixture, and glue is injected into the packaging cavity so that the electric wire with the outer insulating layer removed is covered with glue. The fixture is vibrated to compact the glue in the packaging cavity, and the fixture is left at room temperature to solidify the glue, thereby obtaining a connector with a dual water vapor or water mist blocking function. The connector produced by this method is applied to electrical appliances, which can more effectively prevent water vapor or water mist from penetrating into the interior of the electrical appliances from the gaps between the copper wires, thereby greatly improving the service life of the electrical appliances.

[0038] In an actual production embodiment, the outer insulation layer within a first preset range is removed from the middle of the wire to expose the copper wire in the wire; the outer insulation layer within a second preset range is removed from the middle of the exposed copper wire to facilitate the coating of the copper wire in the copper wire with sealant; wherein the first preset range is 25mm-35mm, and the second preset range is 4mm-6mm.

[0039] Furthermore, if Figure 2 As shown, after at least part of the wire with the outer insulation layer removed is placed in a fixture and the copper wire is fixed in the packaging cavity of the fixture, the method further includes:

[0040] 1031. Perform pre-vibration treatment on the fixture to allow the sealant to penetrate into the gaps between the copper wires;

[0041] 1032. Apply a secondary sealant to the copper wires from which the outer insulation layer has been removed;

[0042] In this embodiment, after the copper wires from which the outer insulating layer is removed are coated with sealant, the copper wires are pre-vibrated to further allow the sealant to more evenly penetrate into the gaps between the copper wires, and the copper wires are coated with sealant a second time, so that the gaps between the copper wires are filled more tightly with sealant.

[0043] Furthermore, at least a portion of the wire, with the outer insulation layer removed, is placed in a fixture, and the copper wire is secured in the fixture's encapsulation cavity, including: at least two copper wires are present, and adjacent copper wires are spaced apart in the fixture's encapsulation cavity. In actual production, there may be multiple wires within a wire. After the outer insulation layer of the copper wire is removed, adjacent copper wires are spaced apart in the fixture's encapsulation cavity to prevent cross-contact between the copper wires within the wire. This ensures that the copper wires within the wire do not contact each other, thereby ensuring that the produced connector can conduct properly.

[0044] Furthermore, if Figure 3 As shown, after the fixture is cooled to obtain the connector, the following steps are also included:

[0045] 201. Soak the connector;

[0046] 202. After the connector has been immersed for a preset time, the connector is dried;

[0047] 203. Connect the dried connector to a power source and check whether its conductivity is normal;

[0048] 204. If the test result is abnormal, the connector is marked as a non-conforming product and placed in a non-conforming area;

[0049] 205. If the test result is normal, the connector is marked as a qualified product and is packaged and put into storage.

[0050] In this embodiment, the connectors are tested for air tightness after production, i.e., the connectors are immersed in water, and then the connectors are electrically tested, i.e., the connectors are connected to a power source and tested for normal conductivity, thereby greatly improving the production quality of the connectors. In addition, unqualified products are placed in an unqualified area so that they can be uniformly recycled, thereby saving production costs.

[0051] like Figure 4 As shown, the present invention also provides a connector production and manufacturing system, which is used to implement the connector production and manufacturing method in the above embodiment, and includes: a wire stripping unit 301, used to remove at least part of the outer insulation layer on the wire 10, and remove at least part of the outer insulation layer on the copper wire 20; a glue coating unit 302, used to apply sealant to the copper wire in the copper wire 20; an injection molding unit 303, used to place the wire 10 in a fixture, and fix the copper wire 20 in the packaging cavity of the fixture; a vibration unit 304, used to inject glue into the packaging cavity and vibrate the fixture so that the copper wire 20 and the wire 10 are wrapped in the packaging cavity by the glue.

[0052] In certain embodiments, in combination Figure 5 and Figure 6As can be understood, the fixture 1 includes a shell 11 and a top cover 12. The shell 11 is provided with a packaging cavity. The bottom of the packaging cavity is provided with a plurality of separators 111 for separating the copper wires 20. The separators 111 are spaced apart. End caps 13 are provided at the two side ports of the packaging cavity. The end caps 13 are used to fix the wires 10 in the packaging cavity. The top cover 12 is connected to the top opening of the packaging cavity. In actual application, two or more copper wires 20 are separated by the separators 111, thereby ensuring that the copper wires 20 do not cross-contact with each other after the glue is injected into the packaging cavity. In addition, the gaps between the copper wires 20 are made more uniform, so that the glue can fill the gaps between the copper wires 20 more evenly.

[0053] In certain embodiments, as Figure 7 As shown, at least one glue injection hole 131 is provided on the top of the end cap 13, a first glue injection groove 132 corresponding to the glue injection hole 131 is provided on the bottom of the end cap 13, and a second glue injection groove 112 corresponding to the first glue injection groove 132 is provided on the inner wall of the packaging cavity. In the actual production process, a gap is formed after a portion of the outer insulation layer of the wire 10 is removed, and a portion of the copper wire 20 is exposed through the gap. By injecting glue into the glue injection hole 131, the glue fills the first glue injection groove 132 and the second glue injection groove 112, so that the outer insulation layer at both ends of the gap on the wire 10 can be covered and sealed by the glue in the first glue injection groove 132 and the second glue injection groove 112, thereby preventing water vapor or water mist from entering the wire 10 through the gaps on both sides of the gap.

[0054] Preferably, if Figure 10 As shown, in some embodiments, a plurality of spaced-apart ring portions 133 are provided at the bottom of the end cap 13. The ring portions 133 are used to wrap the outer insulation layer around the ends of the notch on the wire 10. When the tooling fixture 1 is injection-molded, the end cap 13 is bonded to the wire 10. The sealing effect of the ring portions allows the notch on the wire 10 to be sealed more tightly, further improving the blocking effect of the connector.

[0055] Further preferably, in an actual production implementation, the glue injection hole 131 can be omitted at the top of the end cover 13. During assembly, the end cover 13 is first spliced ​​together with part of the outer insulation layer at both ends of the notch on the wire 10 by injection molding, that is, part of the outer insulation layer at both ends of the notch on the wire 10 is completely surrounded and sealed by the end cover 13, and then the wire 10 with the spliced ​​end cover 13 is placed in the packaging cavity of the shell 11 for glue injection, so that the exposed copper wire 20 and the copper wire in the notch of the wire 10 are sealed by glue, so that the wire 10 can be prevented from sliding in the packaging cavity of the shell 11 during the glue injection process, thereby ensuring the accuracy of the position between the end cover 13 and the wire 10, and further improving the production quality of the connector.

[0056] In certain embodiments, as Figure 5and Figure 8 As shown, at least one positioning portion 134 is provided on each of the two outer side walls of the end cap 13, and a positioning groove 113 corresponding to the positioning portion 134 is provided on the inner side wall of the packaging cavity. The positioning portion 134 is slidably connected to the positioning groove 113. The positioning portion 134 and the positioning groove 113 are connected to each other to position the end cap 13, thereby preventing the end cap 13 from sliding out of the two side ports of the packaging cavity.

[0057] In certain embodiments, in combination Figure 5 、 Figure 8 and Figure 9 It can be understood that a number of positioning posts 121 are provided at the bottom of the top cover 12, a first groove 114 is provided on the inner wall of the packaging cavity, and a second groove 135 is provided on the outer wall of the end cover 13. The first groove 114 and the second groove 135 constitute a positioning hole, and the positioning post 121 is slidably connected to the positioning hole. Through the positioning function of the positioning post 121 and the positioning hole, the top cover 12 and the top opening of the packaging cavity are precisely connected. At the same time, by forming a positioning hole through the first groove 114 and the second groove 135, the thickness of the side wall of the packaging cavity can be made thinner, reducing the material loss in manufacturing the shell 11, thereby saving the manufacturing cost of the fixture 1. It should be noted that the length of the positioning post 121 can be set according to actual needs, so Figure 5 Although there are differences in the lengths of the positioning posts 121 shown in the figures, the normal use of the positioning posts 121 is not affected.

[0058] Preferably, the bottom of the top cover 12 is provided with a plurality of spaced-apart reinforcing ribs 122. In actual use, after the packaging cavity is injected with glue, the top cover 12 and the shell 11 are pressed together. The reinforcing ribs 122 can increase the compressive strength of the top cover 12, further improving the service life of the top cover 12.

[0059] The present invention also provides a connector, which is manufactured using the connector manufacturing method described in any of the above embodiments.

[0060] In summary, the present application removes at least part of the outer insulating layer on the electric wire 10, and removes at least part of the outer insulating layer on the copper wire 20, applies sealant to the copper wires in the copper wire 20, allows the sealant to penetrate into the gaps between the copper wires, and seals the gaps between the copper wires, fixes the copper wire 20 through the packaging cavity of the fixture 1, injects glue into the packaging cavity so that the electric wire 10 with the outer insulating layer removed is covered with glue, vibrates the fixture 1 so that the glue in the packaging cavity can be compacted, and then leaves the fixture 1 at room temperature to solidify the glue, thereby obtaining a connector with dual water vapor or water mist blocking function. The connector produced by this method is applied to electrical appliances, which can more effectively prevent water vapor or water mist from penetrating into the interior of the electrical appliances from the gaps between the copper wires, thereby greatly improving the service life of the electrical appliances.

[0061] It is understandable that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of the present invention, and all such changes or substitutions should fall within the scope of protection of the present invention.
