Description

Technical Field

[0001] This application relates to the field of electrical connector technology, and in particular to a mixed-assembly terminal structure and a mixed-assembly type connector. Background Technology

[0002] Electrical connectors are common connecting elements used in electromechanical equipment. They can connect two electrical components to transmit current or signals. With the continuous upgrading of electromechanical equipment, the number of electrical components included in these devices has gradually increased, resulting in numerous interfaces and messy wiring. Therefore, to reduce the number of interfaces and facilitate cable management, hybrid connectors have been proposed in traditional technology. Hybrid connectors contain a variety of different transmission terminals. After insertion, all the transmission terminals within the hybrid connector are conductive.

[0003] However, some transmission terminals in mixed-assembly connectors need to carry relatively large currents. Current mixed-assembly connectors have insufficient insulation strength, posing a risk of insulation failure when used in high-voltage environments. Utility Model Content

[0004] Therefore, it is necessary to provide a mixed-assembly terminal structure and a mixed-assembly connector to address the problem of insufficient insulation strength in current mixed-assembly connectors.

[0005] This application provides a mixed-type plug structure, which includes an insulator, a first terminal, and a second terminal. The insulator includes a body, a boss, and a cylinder. The boss is located in a portion of the end of the body, and the cylinder is connected to the end of the boss facing away from the body. The first terminal extends axially through the body, the boss, and the cylinder. The second terminal passes through the body, and its end extends out of the body from the area on the end face of the body where the boss is not located. In a direction perpendicular to the axial direction of the insulator, the radial dimension of the second terminal is smaller than that of the first terminal, so as to carry a relatively small current.

[0006] In one embodiment, the body has a first end face, the boss is disposed on the first end face, and along the axial direction of the insulator, the dimension by which the first terminal extends outward relative to the first end face is greater than the dimension by which the second terminal extends outward relative to the first end face.

[0007] In one embodiment, the body includes a head end and a tail end disposed opposite to each other, the boss is disposed at the head end, the insulator also includes partitions, a plurality of partitions are disposed at the tail end, the outer sides of the plurality of partitions are spaced apart in the circumferential direction of the body, and the inner sides of the plurality of partitions are interconnected in a relatively central region to divide the tail space after the tail end into a plurality of fan-shaped and mutually isolated distribution areas; a plurality of second terminals are arranged in the same distribution area, and a plurality of first terminals are arranged one-to-one in other distribution areas.

[0008] In one embodiment, the insulator further includes an outer sleeve disposed at the tail end, and the outer sleeve is sleeved around the outer periphery of the plurality of partitions and connected to the outer side of the plurality of partitions; along the axial direction of the insulator, the length of the first terminal extending beyond the end face of the tail end is L1, the length of the second terminal extending beyond the end face of the tail end is L2, the length of the outer sleeve to the end face of the tail end is L3, and the length of the partition to the end face of the tail end is L4, wherein L3≤L1≤L4, L3≤L2≤L4.

[0009] In one embodiment, the inner sides of the plurality of partitions are connected to each other in the central region to form a central axis portion, the central axis portion having a second hole extending along the axial direction of the insulator, the end of the second hole away from the boss communicating with the outside of the insulator.

[0010] In one embodiment, the boss has a first hole extending along the axial direction of the insulator, the first hole extending to the body and the end of the first hole away from the body communicating with the outside of the insulator.

[0011] In one embodiment, the insulator has a first mounting hole and a second mounting hole extending through it along the axial direction. The first mounting hole extends and is distributed on the body, the boss, and the cylinder. The second mounting hole is opened on the body and corresponds to the area on the body where the boss is not provided. The outer periphery of the first terminal has a first ring portion protruding from it, and the first ring portion is interference-fitted with the hole wall of the first mounting hole. The outer periphery of the second terminal has a second ring portion, and the second ring portion is interference-fitted with the hole wall of the second mounting hole.

[0012] In one embodiment, the mixed-assembly plug structure further includes a housing, the housing including a positioning block, and a positioning groove is formed on the outer periphery of the insulator, the positioning block being axially inserted into the positioning groove.

[0013] In one embodiment, the insulator further includes a positioning ring fitted around the body, the positioning groove being formed in the positioning ring, and the bottom wall of the positioning groove having the same outer diameter as the body.

[0014] Another aspect of this application provides a mixed-assembly connector, which includes the mixed-assembly terminal structure described above.

[0015] In the aforementioned mixed-type connector structure, the first terminal is used to carry a relatively large current relative to the second terminal. Therefore, the first terminal is configured to pass through the body, boss, and cylinder. The body, boss, and cylinder can fully enclose the first terminal, reducing the risk of arcing between the first and second terminals and thus breaking down the insulator. In short, this arrangement increases the creepage distance between the first and second terminals, improving the insulation strength of the mixed-type connector structure. Furthermore, the second terminal extends outward from the area of ​​the body end face where no boss is provided, meaning the second terminal is distributed in the area of ​​the body where no boss is provided. Therefore, the path length along the insulator surface from the first terminal to the second terminal is relatively extended, increasing the creepage distance and further improving the insulation strength of the connector.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0026] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0028] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0029] It should be noted that the hybrid plug-in structures provided in the embodiments of this application can enhance the insulation strength of the hybrid plug-in structure and the hybrid connector including the hybrid plug-in structure by increasing the creepage distance. The creepage distance refers to the shortest path along an insulating surface (e.g., the surface of the insulator mentioned below) from one conductive part (e.g., the first terminal mentioned below) to another conductive part (e.g., the second terminal mentioned below). The hybrid plug-in structures provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. Furthermore, the following description will take the insertion of the hybrid plug-in structure and the mating structure as an example, where one of the hybrid plug-in structure and the mating structure is the female end and the other is the male end.

[0030] See Figures 1 to 3 , Figure 1 This paper shows an isometric schematic diagram of a hybrid plug-in structure provided in an embodiment of the present application. Figure 2 for Figure 1 The exploded view of the mixed-assembly plug structure shown is as follows. Figure 3 for Figure 1 The diagram shows an isometric view of the insulator, first terminal, and second terminal in the mixed-assembly plug structure. An embodiment of this application provides a mixed-assembly plug structure 10 including a first terminal 100, a second terminal 200, and an insulator 300. Both the first terminal 100 and the second terminal 200 pass through the insulator 300. The insulator 300 includes a body 310, a boss 320, and a cylindrical body 330. The boss 320 is located in a portion of the end of the body 310, and the cylindrical body 330 is connected to the end of the boss 320 facing away from the body 310. That is, the body 310, the boss 320, and the cylindrical body 330 are axially connected end-to-end. The first terminal 100 extends along the axial direction O of the insulator 300 and passes through the body 310, the boss 320, and the cylindrical body 330. The second terminal 200 passes through the body 310, and the end of the second terminal 200 extends outward from the area of ​​the body 310 where the boss 320 is not located. In the direction perpendicular to the axial direction O of the insulator 300, the radial dimension of the second terminal 200 is smaller than that of the first terminal 100, and is used to carry a relatively small current.

[0031] In the aforementioned mixed-type connector structure 10, the first terminal 100 is used to carry a relatively large current relative to the second terminal 200. Therefore, the first terminal 100 is configured to pass through the body 310, the boss 320, and the cylindrical body 330. The body 310, the boss 320, and the cylindrical body 330 can fully enclose the first terminal 100, reducing the risk of arcing between the first terminal 100 and the second terminal 200, which could damage the insulator 300. In short, this arrangement increases the creepage distance between the first terminal 100 and the second terminal 200, improving the insulation strength of the mixed-type connector structure 10. Furthermore, the second terminal 200 extends out of the body 310 from the area on the end face where the boss 320 is not located; that is, the second terminal 200 is distributed in the area of ​​the body 310 where the boss 320 is not located. Therefore, the path length along the surface of the insulator 300 from the first terminal 100 to the second terminal 200 is relatively extended, increasing the creepage distance and further improving the insulation strength of the connector.

[0032] Please continue reading. Figure 2 and Figure 3 In one embodiment, there are multiple cylindrical bodies 330, which are connected to the bosses 320 at intervals. There are also multiple first terminals 100, which are distributed one-to-one within the multiple cylindrical bodies 330. This arrangement relatively hollows out the space between the multiple cylindrical bodies 330, thereby further increasing the creepage distance between the individual first terminals 100.

[0033] Please see Figure 3In one embodiment, the insulator 300 has a first mounting hole 301 and a second mounting hole 302 extending through it along the axial direction O. The first mounting hole 301 extends and is distributed in the body 310, the boss 320, and the cylinder 330. The second mounting hole 302 is formed in the body 310 and corresponds to the area of ​​the body 310 where the boss 320 is not provided. The outer periphery of the first terminal 100 has a first ring portion 210 protruding, which is press-fitted with the wall of the first mounting hole 301, so that the first terminal 100 can be fixedly installed in the first mounting hole 301 for easy insertion. The outer periphery of the second terminal 200 has a second ring portion 220, which is press-fitted with the wall of the second mounting hole 302, so that the second terminal 200 can be fixedly installed in the second mounting hole 302 for easy insertion.

[0034] Referring to Figure 3, in one embodiment, the body 310 includes a head end 311 and a tail end 312 disposed opposite to each other. The head end 311 is the end relatively close to the mixed-assembly plug-in structure 10 for insertion with the mating structure, while the tail end 312 is the end relatively far from the mixed-assembly plug-in structure 10 for insertion with the mating structure. A boss 320 is provided on the head end 311.

[0035] Please see Figure 3 Combined Figure 6 In one embodiment, the body 310 has a first end face 311a, and a boss 320 is disposed on the first end face 311a, that is, the first end face 311a is the end face of the head end 311. Along the axial direction O of the insulator 300, the extension dimension of the first terminal 100 relative to the first end face 311a is greater than the extension dimension of the second terminal 200 relative to the first end face 311a. That is, the ends of the first terminal 100 and the ends of the second terminal 200 are misaligned along the axial direction O of the insulator 300. Therefore, when the mixed-assembly plug structure 10 is inserted, the misaligned contact of the corresponding terminals of the mating structure can reduce interference. It should be noted that when the extension dimensions of the first terminal 100 and the second terminal 200 are the same as described above, there is a certain voltage magnetic field between them. Therefore, when the mixed-assembly plug structure 10 comes into contact with the mating structure, an arc discharge phenomenon will occur, which can easily damage the insulator 300. In this embodiment, the ends of the first terminal 100 and the second terminal 200 are axially offset, so that they do not simultaneously contact the terminals of the mating structure, which can effectively reduce the risk of the above-mentioned damage.

[0036] Please see Figures 4 to 6In one embodiment, the insulator 300 further includes partitions 340, with multiple partitions 340 disposed at the tail end 312. The outer edges of the multiple partitions 340 are spaced apart in the circumferential direction of the body 310, and the inner edges of the multiple partitions 340 are interconnected at a relatively central region to divide the tail space after the tail end 312 into multiple distribution areas 303, which are fan-shaped and isolated from each other. Multiple second terminals 200 are arranged in the same distribution area 303, and multiple first terminals 100 are arranged one-to-one in other distribution areas 303. Since the distribution areas 303 are isolated from each other, a larger creepage distance can be achieved between the distribution areas 303. Since the second terminals 200 carry relatively small currents, arranging multiple second terminals 200 in the same distribution area 303 reduces the likelihood of insulation failure. Arranging multiple second terminals 200 in the same distribution area 303 facilitates unified assembly. Since the first terminal 100 carries a relatively large current, multiple first terminals 100 are arranged one-to-one in other distribution areas 303 to increase the creepage distance between the first terminals 100, thereby giving the insulator 300 better insulation strength.

[0037] Please see Figure 4 and Figure 6 In one embodiment, the insulator 300 further includes an outer sleeve 350, which is disposed at the tail end 312 and is wrapped around the outer periphery of the plurality of partitions 340 and connected to the outer side of the plurality of partitions 340, so that the first terminal 100 or the second terminal 200 located in one distribution area 303 has a larger creepage distance with the first terminal 100 or the second terminal 200 located in another distribution area 303, thereby improving the insulation strength.

[0038] Further, along the axial direction O of the insulator 300, the length of the first terminal 100 extending beyond the end face of the tail end 312 (i.e., the second end face 312a) is L1, the length of the second terminal 200 extending beyond the end face of the tail end 312 is L2, the length of the outer sleeve 350 to the end face of the tail end 312 is L3, and the length of the partition 340 to the end face of the tail end 312 is L4. Wherein, L3≤L1≤L4, L3≤L2≤L4. That is, two adjacent partitions 340 can form a recess 304 with the arcuate region of the outer sleeve 350 located between the two partitions 340, allowing the distribution area 303 to communicate with the outside of the outer sleeve 350. Furthermore, the first terminal 100 and the second terminal 200 located within the distribution area 303 can be exposed to the outside of the outer sleeve 350 through the recess 304. It is understandable that in practical applications of the mixed-plug structure 10, the tails of the first terminal 100 and the second terminal 200 usually need to be connected to cables, for example, by soldering the cables to the tails of the first terminal 100 and the second terminal 200. Therefore, in this embodiment, the recess 304 is configured to facilitate the connection of the cables to the tails of the first terminal 100 and the second terminal 200.

[0039] Please see Figure 4 and Figure 6 In one embodiment, the boss 320 has a first hole 305 extending along the axial direction O of the insulator 300. The first hole 305 extends to the body 310, and the end of the first hole 305 away from the body 310 communicates with the outside of the insulator 300. On the one hand, since the cylindrical body 330 surrounding the first terminal 100 is provided on the boss 320, the provision of a second hole 306 on the boss 320 can further increase the creepage distance at the boss 320. On the other hand, the insulator 300 can be integrally injection molded, and the provision of the first hole 305 can reduce the overall glue thickness of the boss 320 and the body 310, reducing the risk of shrinkage and deformation during the processing and molding of the insulator 300.

[0040] Please refer to section 6. In one embodiment, the inner edges of a plurality of partitions 340 are interconnected in a central region to form a central shaft portion 341. The central shaft portion 341 has a second hole 306 extending along the axial direction O of the insulator 300, and the end of the second hole 306 away from the boss 320 communicates with the outside of the insulator 300. Similarly, the configuration of the second hole 306 can further increase the creepage distance at the tail end and reduce the risk of shrinkage deformation at the central shaft portion 341 during the processing and molding of the insulator 300.

[0041] Please see Figure 6 Combined Figure 3 and Figure 4In one embodiment, the mixed-assembly plug structure 10 further includes a housing 400, which includes a positioning block 410. A positioning groove 361 is provided on the outer periphery of the insulator 300, and the positioning block 410 is axially inserted into the positioning groove 361 to facilitate quick positioning and assembly of the housing 400 and the insulator 300.

[0042] Please see Figure 6 Combined Figure 3 and Figure 4 In one embodiment, the insulator 300 further includes a positioning ring 360. The positioning ring 360 is fitted over the body 310, and a positioning groove 361 is formed in the positioning ring 360, with the bottom wall of the positioning groove 361 having the same outer diameter as the body 310. This makes the outer periphery of the insulator 300 relatively regular, improving the smoothness of the insertion of the housing 400. For example, when the housing 400 and the insulator 300 are inserted, the positioning block 410 can slide along the outer periphery of the body 310 to the position where it is inserted into the positioning groove 361.

[0043] In one embodiment, the first terminal 100 can be configured as a socket terminal and the second terminal 200 can be configured as a pin terminal. Of course, the same applies if the first terminal 100 is configured as a pin terminal and the second terminal 200 is configured as a socket terminal.

[0044] One embodiment of this application also provides a mixed-assembly connector, which includes a mixed-assembly plug structure 10 as described in various embodiments, thus the mixed-assembly connector has better insulation strength.

[0045] Furthermore, the mixed-assembly connector may also include a mating structure, wherein the mixed-assembly mating structure 10 and the mating structure may each have one as a female end and the other as a male end. Even further, the mating structure may have a structural shape and terminal configuration corresponding to the mixed-assembly mating structure 10, to facilitate mating between the two.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
