[0043] According to a first aspect of the present invention, there is provided an insulator including a first insulating member 10 and a second insulating member 20 .

[0044] Hereinafter, specific structures of the above-mentioned components of the insulator according to the present embodiment will be described.

[0045] In this embodiment, if Figure 1 and Figure 2 As shown, the insulator is in a cylindrical structure as a whole; the insulator is formed with a through hole 30 which penetrates its main body and extends along the axis of the insulator, and connecting parts are provided on the outer wall of the insulator and the hole wall of the through hole 30, and the connecting parts are used to connect the contact terminals; in a preferred embodiment, the axis of the through hole 30 is colinear with the axis of the insulator main body.

[0046] Specifically, in this embodiment, Figures 1 to 6 As shown, there are multiple connecting parts arranged on the outer wall of the insulator, and the multiple connecting parts are arranged at equal intervals around the circumference of the side wall of the insulator. In an optional embodiment, there is only one connecting part arranged on the hole wall of the through hole 30.

[0047] More specifically, in this embodiment, if Figures 1 to 6 As shown, the connection part is formed into an annular structure with an opening 43, and the size of the opening 43 is smaller than the inner diameter of the annular structure, so that the opening 43 is formed into a constricted structure. Here, the shape of the connection part can be understood as a U-shaped structure similar to a closed end. The insulator is made of a plastic material with insulating properties and has a certain elasticity. The opening 43 is formed into a constricted structure so that when the contact terminal is assembled, the opening 43 is squeezed to deform and open so that the contact terminal can enter the annular structure of the connection part and abut against the inner wall of the annular structure, thereby ensuring that the contact terminal is installed in place. After the contact terminal abuts against the inner wall of the annular structure, the deformed and opened opening 43 returns to its original shape and the contact terminal is enclosed in the annular structure so that the connection part is surrounded by the circumferential side wall of the contact terminal, ensuring that the contact terminal is firmly installed on the connection part, which has the advantage of being easy to install and remove.

[0048] In a preferred embodiment, the connecting portion is formed into an ellipse-like structure, wherein the extending direction of the major axis of the ellipse is consistent with the direction of the force applied for assembly and disassembly of the contact terminal.

[0049] In this embodiment, if Figures 1 to 6 As shown, along the axial section of the insulator, the insulator is formed into a first insulating member 10 and a second insulating member 20 that are detachably connected, that is, the insulator of the cylindrical structure is divided into two halves along the axial section of the cylinder, so that the first insulating member 10 and the second insulating member 20 form a structure that is approximately a semi-cylindrical structure, so that the contact terminals located on the inner wall of the through hole 30 are easy to disassemble and assemble, thereby improving the assembly efficiency of the connector.

[0050] Specifically, in this embodiment, Figures 3 to 6As shown, one side of the first insulating member 10 facing the second insulating member 20 is formed as a first assembly portion 11, and one side of the second insulating member 20 facing the first insulating member 10 is formed as a second assembly portion 21. When the first insulating member 10 and the second insulating member 20 are assembled into an insulator, the first assembly portion 11 and the second assembly portion 21 are in contact with each other.

[0051] In a preferred embodiment, Figures 1 to 6 As shown, the first insulating member 10 is snap-fitted with the second insulating member 20 , which facilitates the connection and separation of the first insulating member 10 and the second insulating member 20 , thereby improving the assembly efficiency of the insulator and ensuring reliable assembly.

[0052] Specifically, in this embodiment, Figures 3 to 6 As shown, the first assembly portion 11 is formed with a protruding clamping portion 13, and the second assembly portion 21 is formed with a clamping groove 23 for the clamping portion 13 to extend into. In a preferred embodiment, the clamping portion 13 is arranged at the outer edge of the first insulating member 10, and the clamping groove 23 is correspondingly arranged at the end of the second assembly portion 21 in the width direction (i.e., in the radial direction of the insulator) to ensure that the first insulating member 10 and the second insulating member 20 are easy to disassemble and assemble. More specifically, the end of the clamping portion 13 is formed as a hook structure extending inward, so that the clamping groove 23 can be hooked to prevent the first insulating member 10 and the second insulating member 20 from loosening.

[0053] In addition, if Figure 3 and Figure 4 As shown, the clamping parts 13 on the first assembly part 11 are preferably provided in two, the clamping grooves 23 are provided corresponding to the clamping parts 13, the two clamping parts 13 are located at both ends of the first assembly part 11, and the hook structures on the two clamping parts 13 extend relative to each other, so that after the first insulating part 10 and the second insulating part 20 are assembled, the second assembly part 21 can be tightly attached to the first assembly part 11 to ensure the connection reliability of the insulator.

[0054] Furthermore, in this embodiment, if Figures 3 to 6 As shown, the outer walls of the first insulating member 10 and the second insulating member 20 are each provided with at least one connection portion, and the connection portion on the first insulating member 10 and the connection portion on the second insulating member 20 are arranged in mirror symmetry with each other to ensure that the connection portions arranged on the outer wall of the insulator are distributed at equal intervals, and at the same part volume, this structure can realize dense installation of contact terminals. In this embodiment, the first insulating member 10 and the second insulating member 20 are each provided with two connection portions, but it can also be set to one or more connection portions according to actual needs.

[0055] In addition, the clamping portion 13 and the clamping groove 23 preferably extend along the axial direction of the insulator to both end surfaces of the insulator to form a long strip structure, thereby further improving the connection reliability of the first insulating member 10 and the second insulating member 20.

[0056] Specifically, in this embodiment, Figures 1 to 6 As shown, the connecting parts on the first insulating member 10 and the second insulating member 20 include a first connecting part 41 and a second connecting part 42, wherein the first connecting part 41 is arranged on the hole wall of the through hole 30 on the first insulating member 10, a part of the first connecting part 41 extends out of the outside of the first assembly part 11, and the hole wall of the through hole 30 on the second insulating member 20 is recessed inward to form a semicircular annular groove 31 for a part of the first connecting part 41 to extend into, and the axis of the annular groove 31 is colinear with the axis of the through hole 30.

[0057] During the assembly process of the insulator, the contact terminal located in the through hole 30 can be first assembled on the first connecting portion 41, and then the first insulating member 10 and the second insulating member 20 can be assembled. In this way, the contact terminal located in the through hole 30 does not need to use additional removal tools, which has the advantage of easy removal and installation.

[0058] In addition, the second connection portion 42 is disposed on the circumferential outer wall of the insulator, and the openings 43 are disposed toward the outside of the insulator body. In this embodiment, the first connection portion 41 and the second connection portion 42 are located on the same cross section perpendicular to the axis of the insulator.

[0059] In this embodiment, if Figures 1 to 6 As shown, the first assembly portion 11 is formed with a protruding insulating rib 12, and the second assembly portion 21 is formed with an inwardly recessed assembly groove 22, so that the insulating rib 12 can be inserted when the first insulating member 10 and the second insulating member 20 are assembled. The insulating rib 12 and the assembly groove 22 are arranged between the first connecting portion 41 and the second connecting portion 42 to increase the creepage distance between the contact terminal installed on the first connecting portion 41 and the contact terminal installed on the second connecting portion 42, thereby improving the insulation performance of the connector and ensuring the safety of the electrical equipment. In addition, the insulating rib 12 and the assembly groove 22 also have the function of assembling and positioning the first insulating member 10 and the second insulating member 20, so as to ensure that the clamping portion 13 smoothly extends into the clamping groove 23.

[0060] Specifically, in the present embodiment, the insulating ribs 12 and the assembly grooves 22 are both formed into strip structures extending along the axis of the through hole 30 , and are arranged in pairs on both sides of the through hole 30 in the radial direction.

[0061] In this embodiment, if Figures 1 to 6 As shown, the outer wall of the insulator is formed with an insulating groove 50 extending along the axial direction of the through hole 30 and penetrating its main body. The connecting portion arranged on the outer wall of the insulator is embedded in the insulating groove 50 to provide space for the installation of the contact terminal and form effective insulation protection. The axial extension direction of the connecting portion of the annular structure is consistent with the extension method of the insulating groove 50.

[0062] In addition, in this embodiment, Figure 1 and Figure 2 As shown, the side wall of the insulator is provided with an identification groove 60, which extends along the axial direction of the through hole 30 and runs through the main body of the insulator, so that the insulator has an anti-misinstallation structure, thereby avoiding misoperation during the connector assembly process, and further improving the assembly efficiency of the connector. In an embodiment, the identification groove 60 can be arranged between two adjacent insulating grooves 50, and the identification groove 60 can be arranged on the second insulating member 20. It should be noted that when a positioning boss 70 is provided on the insulator, the identification groove 60 runs through the positioning boss 70.

[0063] It should be further explained that, in this embodiment, the insulator has multiple groups of mutually cooperatively connected bump-like structures and groove-like structures. In a preferred embodiment, the bump-like structures are all arranged on the first insulating member 10, and the groove-like structures are all arranged on the second insulating member 20 to improve assembly processability.

[0064] In this embodiment, if Figures 1 to 6 As shown, a positioning boss 70 protruding outward is formed at one end of the insulator in the length direction. The positioning boss 70 protrudes outward from the side wall of the insulator and protrudes outward along the end of the insulator to facilitate the assembly of the insulator with the housing of the connector.

[0065] In this embodiment, if Figures 1 to 6 As shown, the connection portion and the positioning boss 70 are located at two ends of the insulator in the length direction, that is, the connection portion is arranged on an end of the insulator away from the positioning boss 70 .

[0066] In this embodiment, the insulator is formed by injection molding. In order to avoid holes or uneven wall thickness in the insulator during the injection molding process, the outer wall of the positioning boss 70 is formed with an inwardly recessed process groove 80, so that the wall thickness of the insulator body is more uniform, thereby improving the processing processability of the part. In the embodiment, a plurality of process grooves 80 are provided, and the plurality of process grooves 80 are arranged at intervals around the circumference of the insulator. Process grooves 80 are provided on both sides of the insulation groove 50.

[0067] The insulator according to the present invention has a simple structure, low manufacturing cost, and is easy to connect and assemble. The first insulator and the second insulator that are detachably connected are provided to facilitate the removal and installation of the contact terminal without the need for additional removal tools, thereby improving the assembly efficiency of the connector. The first insulator and the second insulator are connected by a snap connection, which can further improve the assembly efficiency and ensure reliable assembly.

[0068] Secondly, by providing insulating ribs and assembly grooves, the electrical clearance and creepage distance between the contact terminal of the connecting part installed in the through hole and the contact terminal of the connecting part installed on the outer wall of the insulator body are improved, which is beneficial to improving the insulation performance of the connector; and an insulating groove corresponding to the connecting part is provided on the side wall of the insulator body to provide space for the installation of the contact terminal and form effective insulation protection.

[0069] In addition, by providing an identification groove on the outer wall of the insulator body, the insulator has an anti-mis-installation structure, thereby avoiding misoperation during the connector assembly process and further improving the connector assembly efficiency.

[0070] Finally, by setting the process groove, the wall thickness of the insulator body is made more uniform, improving the processing performance of the parts.

[0071] A second aspect of the present invention provides a connector, which is applied to the insulator described in the above embodiment. In this embodiment, Figure 7 As shown, the contact terminal 100 is assembled on the insulator 200, which has the advantage of enabling the connector to be quickly disassembled without the need for additional removal tools; in addition, due to the increase in electrical clearance and creepage distance, the insulation of the connector is effectively improved, thereby improving the safety of electrical equipment connected through the connector.

[0072] Finally, it should be noted that the above-described embodiments are only specific implementation methods of the present application, which are used to illustrate the technical solutions of the present application, rather than to limit them. The protection scope of the present application is not limited thereto. Although the present application is described in detail with reference to the above-described embodiments, ordinary technicians in the field should understand that any technician familiar with the technical field can still modify the technical solutions recorded in the above-described embodiments within the technical scope disclosed in the present application, or can easily think of changes, or make equivalent replacements for some of the technical features therein; and these modifications, changes or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, and should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
