Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of the present application.

[0028] In the description of the present application, it should be understood that the orientation or positional relationship indicated by terms such as "thickness", "upper", "lower", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "a plurality of" means two or more, and at least one means one, two or more, unless otherwise specifically defined.

[0029] Referring to Figures 1 to 16 , an embodiment of the present application provides an electrical connector, including a first housing 1 and a plurality of female terminals 2.

[0030] Wherein, the first housing 1 has a first cavity 10, and the first housing 1 has a reference axis 11. A plurality of female terminals 2 are arranged in the first cavity 10, and the plurality of female terminals 2 are spaced apart around the reference axis 11. The plurality of female terminals 2 include a plurality of first terminals 20 and a plurality of second terminals 21. The current-carrying cross-sectional area of the first terminals 20 is larger than that of the second terminals 21. And in the direction around the reference axis 11, at least some second terminals 21 are provided between two adjacent first terminals 20, and the minimum distance between any two first terminals 20 is not less than the minimum distance between any two second terminals 21.

[0031] It should be noted that in the embodiment of the present application, a first direction X, a second direction Y, and a third direction Z that intersect each other in pairs are introduced. Among them, the third direction Z is parallel to the extension direction of the introduced reference axis 11, and at the same time, the plane defined by the first direction X and the second direction Y is perpendicular to the reference axis 11. Specifically, in this embodiment, the contour of the plurality of female terminals 2 distributed around the reference axis 11 is generally elliptical, and the reference axis 11 is also the center of the ellipse passing through the elliptical contour line.

[0032] It is understandable that among the terminals of the same material, the terminals with larger cross-sectional areas of current flow will generate more heat in the working state. In this embodiment, by arranging the first terminal 20 and the second terminal 21 around the reference axis 11, it is avoided that multiple female terminals 2 are closely arranged in only a single direction, which is conducive to further dispersing the arrangement of the female terminals 2 on the basis of reducing the impact on the overall size of the electrical connector. At the same time, the second terminal 21 is set between at least some adjacent first terminals 20, and the minimum distance between any two first terminals 20 is not less than the minimum distance between any two second terminals 21, so as to reduce the mutual thermal influence between the first terminals 20 that generate more heat in the working state, which is conducive to improving the heat dissipation effect of the female terminal 2 and improving the safety of the electrical connector.

[0033] In some embodiments, reference Figure 2 and Figure 3 A plurality of first terminals 20 are arranged at intervals along a first direction X, and a plurality of second terminals 21 are arranged at intervals along a second direction Y. In the direction around the reference axis 11 , a second terminal 21 is provided between two adjacent first terminals 20 .

[0034] Specifically, in this embodiment, a four-position hybrid electrical connector with two first terminals 20 and two second terminals 21 is taken as an example, which ensures that the first terminals 20 and the second terminals 21 are spaced apart from each other and sufficient spacing is reserved between adjacent first terminals 20, which is beneficial to sufficient heat dissipation of the first terminals 20 and the second terminals 21, thereby improving the heat dissipation performance of the electrical connector.

[0035] In addition, in other embodiments, the number of the female terminals 2 may be flexibly increased or decreased as needed, and the number of the first terminals 20 and the second terminals 21 may be adaptively adjusted.

[0036] In some embodiments, reference Figure 3 and Figure 6 , the size of the first cavity 10 in the first direction X is greater than the size of the first cavity 10 in the second direction Y. Specifically, in this embodiment, the size of the first housing 1 in the first direction X is greater than the size in the second direction Y, thereby providing sufficient spacing space for the two first terminals 20 and improving the heat dissipation effect of the terminals with higher heat generation in the use state.

[0037] In some embodiments, reference Figure 2 and Figure 6 The first housing 1 has an opening 12 in the third direction Z that communicates with the first cavity 10 , and the female terminal 2 has a socket opening 22 facing the outside of the opening 12 in the third direction Z.

[0038] The electrical connector further comprises a first locking member 3 , which is connected to the first housing 1 and is configured to fit the female terminal 2 at least in the third direction Z to restrict the female terminal 2 from moving in the third direction Z.

[0039] It can be understood that the socket 22 of the female terminal 2 is mainly for the male terminal 5 to be plugged in and out. During the plugging and unplugging process, the female terminal 2 needs to withstand the force in the third direction Z, and the first locking piece 3 can limit the movement of the female terminal 2 in the third direction Z, thereby improving the socket stability of the female terminal 2.

[0040] Please combine Figures 9 to 12 Based on the distribution structure of the first terminals 20 and the second terminals 21, the first locking member 3 designed in this embodiment is designed with a stopper 30 corresponding to each first terminal 20 and the second terminal 21. Figure 12 In the embodiment, the first locking member 3 is also provided with a pre-locking buckle 31 and a final locking buckle 32 .

[0041] Specifically, in some embodiments, referring to Figure 6 , Figures 9 to 12 The first locking member 3 is adjustable and connected to the first housing 1, and the first locking member 3 has at least a first position and a second position. In this embodiment, the first housing 1 is provided with an introduction port 141 connected to the interior in the second direction Y, and the first locking member 3 is inserted into the first cavity 10 along the second direction Y through the introduction port 141.

[0042] Reference Figure 6 and Figure 11 In the first position, the first locking member 3 is in contact with the female terminal 2 in the third direction Z. The first position also corresponds to the final locking position of the first locking member 3. When the first locking member 3 is in the first position, the final locking buckle 32 is engaged with the first housing 1. Figure 12 The stopper 30 on the first locking member 3 includes a first portion 300 corresponding to one of the second terminals 21, a second portion 301 corresponding to the two first terminals 20, and a third portion 302 corresponding to the other second terminal 21. In the first position, the first terminal 20 and the second terminal 21 are limited in the third direction Z by the first portion 300, the second portion 301, and the third portion 302.

[0043] Reference Figure 7 and Figure 10 In the second position, the first locking member 3 is connected to the first housing 1, and the first locking member 3 is separated from the female terminal 2. The second position also corresponds to the pre-locking position of the first locking member 3. When the first locking member 3 is in the second position, the pre-locking buckle 31 is engaged with the first housing 1. Figure 12 When in the second position, the first part 300, the second part 301 and the third part 302 are mutually misaligned with the first terminal 20 and the second terminal 21 in the third direction Z. At this time, the installation of the female terminal 2 and other related structures can be flexibly adjusted to avoid the first locking piece 3 hindering the installation and adjustment of the female terminal 2 and other structures. At the same time, the pre-locking buckle 31 can ensure that the first locking piece 3 does not separate from the first shell 1, so as to facilitate pushing the first locking piece 3 again to adjust the first position or the second position.

[0044] In some embodiments, referring to Figure 2 , Figure 3 and Figure 6 , the first housing 1 includes an outer housing portion 14 and an inner housing portion 15. The outer housing portion 14 is sleeved on the inner housing portion 15. A first cavity 10 is formed inside the inner housing portion 15, and an opening 12 penetrates the inner housing portion 15. An insertion slot 16 surrounding the inner housing portion 15 is formed between the outer housing portion 14 and the inner housing portion 15. The above-mentioned inlet 141 penetrates the inner housing portion 15 and the outer housing portion 14 to ensure that the first locking member 3 can be inserted into the inner housing portion 15.

[0045] In addition, referring to Figure 3 , an observation port 151 is further formed on the side surface of the inner housing portion 15 in the third direction Z. The observation port 151 corresponds to the position of the final locking buckle 32 in the third direction Z. After the operator inserts the first locking member 3, it is convenient to directly confirm whether the first locking member 3 has been pushed into the first position, that is, whether the final locking buckle 32 is properly latched, through the observation port 151.

[0046] In some embodiments, referring to Figure 2 , Figure 4 and Figure 6 , the electrical connector further includes a second housing 4 and a plurality of male terminals 5. The second housing 4 has a first locking portion 40; the plurality of male terminals 5 include a plurality of third terminals 50 and a plurality of fourth terminals 51. The third terminals 50 and the first terminals 20 are correspondingly arranged, and the fourth terminals 51 and the second terminals 21 are correspondingly arranged. The male terminals 5 are used to be inserted into the socket 22 of the corresponding female terminal 2 to connect the corresponding female terminal 2.

[0047] Specifically, in some embodiments, referring to Figure 2 , Figure 4 and Figure 6 , the second housing 4 includes an end portion 41 and a peripheral side portion 42 connecting the end portion 41. A second cavity 43 is formed by the end portion 41 and the peripheral side portion 42. The male terminals 5 are arranged in the second cavity 43, and the male terminals 5 are connected to the end portion 41; when the male terminals 5 are connected to the corresponding female terminals 2, the peripheral side portion 42 is embedded in the insertion slot 16.

[0048] To quickly lock the first housing 1 and the second housing 4, referring to Figure 2 , Figure 4 and Figure 6 , the first housing 1 is provided with a second locking portion 13 adapted to the first locking portion 40. When the male terminals 5 are connected to the corresponding female terminals 2, the first locking portion 40 locks the second locking portion 13 to prevent the first housing 1 and the second housing 4 from being separated. In this embodiment, the second locking portion 13 adopts a locking hook structure, which can hook the side of the first locking portion 40 close to the end portion 41 during the process of pushing the peripheral side portion 42 into the insertion slot 16.

[0049] In some embodiments, referring toFigure 2 , Figure 6 , Figure 7 , Figure 13 and Figure 14 , the electrical connector further includes a second locking member 6. The second locking member 6 is connected to the first housing 1, and the second locking member 6 is configured to abut against the second housing 4 when the male terminal 5 is connected to the corresponding female terminal 2, so as to limit the second housing 4 from detaching from the first housing 1.

[0050] Specifically, in some embodiments, referring to Figure 13 , the second locking member 6 includes a main body portion 60, a third locking portion 61, and an abutting portion 62. Among them, the main body portion 60 is detachably connected to the first housing 1, the third locking portion 61 is connected to the main body portion 60, and a fourth locking portion 19 adapted to the third locking portion 61 is provided on the first housing 1 to limit the main body portion 60 from detaching from the first housing 1. The abutting portion 62 is connected to the main body portion 60. When the male terminal 5 is connected to the corresponding female terminal 2, the abutting portion 62 abuts against the second housing 4.

[0051] The main body portion 60 is formed with a slide rail 600 adapted to the structure of the outer shell portion 14, that is, the second locking member 6 can be inserted into the insertion slot 16 by the outer shell portion 14 on one side away from the opening 12 in the third direction Z. The third locking portion 61 is designed as a hook structure and can hook the fourth locking portion 19 when the second locking member 6 is inserted into the insertion slot 16, so as to limit the whole second locking member 6 from detaching from the first housing 1.

[0052] Similar to the first locking member 3, in this embodiment, the second locking member 6 is also designed with a pre-locking position and a final locking position on the first housing 1. Synchronously referring to Figure 14 , a first convex portion 601 protruding toward the outer shell portion 14 is provided on the main body portion 60, and a second convex portion 140 is correspondingly provided on the outer shell portion 14. The first convex portion 601 and the second convex portion 140 are arranged in the third direction Z. At the same time, referring to Figure 13 , the abutting portion 62 is provided with a limiting portion 63.

[0053] Synchronously referring to Figure 7 , in the pre-locking position, the limiting portion 63 abuts against the inner shell portion 15 in the third direction Z. At this time, the third locking portion 61 can hook the fourth locking portion 19, but the abutting portion 62 cannot move forward further due to the limitation of the limiting portion 63. Therefore, only the detachment of the second locking member 6 from the first housing 1 is limited.

[0054] Synchronously referring to Figure 6, in the final locked position, when the peripheral side portion 42 is inserted into the insertion slot 16, since the first locking portion 40 pushes the abutting portion 62 upward to cause it to tilt, the limiting portion 63 can be displaced from the structure on the inner housing portion 15 that obstructs the movement of the limiting portion 63 in the third direction Z. At this time, the overall second locking member 6 can be further inserted into the insertion slot 16, so that the first convex portion 601 and the second convex portion 140 cooperate, and the second convex portion 140 restricts the first convex portion 601 and the overall second locking member 6 from detaching from the first housing 1. This is beneficial to further improve the connection stability between the first housing 1 and the second housing 4.

[0055] In addition, in order to quickly position and dock the first housing 1 and the second housing 4, referring to Figure 2 and Figure 4 , a first guide block 44 extending along the third direction Z is further provided on the peripheral side portion 42, and the first guide block 44 cooperates with the groove wall of the insertion slot 16 to guide the quick docking of the first housing 1 and the second housing 4.

[0056] In order to improve the sealing performance of the docking between the first housing 1 and the second housing 4 and improve the insulation and sealing effect of the overall electrical connector in the use state of the mating of the male terminal 5 and the female terminal 2, in some embodiments, referring to Figure 2 , Figure 6 and Figure 8 , the electrical connector further includes a sealing member 7. The sealing member 7 is disposed in the insertion slot 16, and the sealing member 7 is sleeved on the inner housing portion 15. When the male terminal 5 is connected to the corresponding female terminal 2, the peripheral side portion 42 and the inner housing portion 15 abut against the sealing member 7.

[0057] The sealing member 7 can be made of insulating rubber material, etc. The sealing member 7 is connected to the inner housing portion 15 by interference fit and is sleeved by the peripheral side portion 42, thereby improving the sealing effect of the connection area between the male terminal 5 and the female terminal 2 after the connection of the first housing 1 and the second housing 4.

[0058] In some embodiments, referring to Figure 2 , Figure 6 , Figure 8 and Figure 15 , the electrical connector further includes a third locking member 70. The third locking member 70 is disposed in the insertion slot 16, and the third locking member 70 is disposed on the side of the sealing member 7 close to the opening 12. The third locking member 70 is detachably connected to the inner housing portion 15 to restrict the sealing member 7 from detaching from the inner housing portion 15.

[0059] Specifically, referring to Figure 8 and Figure 15 , the inner peripheral wall of the third locking member 70 is provided with a seventh locking portion 700, and a clamping groove 152 for the seventh locking portion 700 to be inserted is correspondingly provided on the inner housing portion 15. When the third locking member 70 is inserted into the insertion slot 16, the first housing 1 can be positioned and connected through the seventh locking portion 700, so as to prevent the sealing member 7 from detaching from the inner housing portion 15 through the overall third locking member 70.

[0060] In addition, it should be noted that for synchronous reference Figure 15 , in order to prevent the third locking member 70 from obstructing the use of the first locking member 3, a relief opening 702 is also provided in the third locking member 70, and the relief opening 702 corresponds to the above-mentioned guiding inlet 141.

[0061] In addition, in order to guide the third locking member 70 to quickly and accurately align with the insertion slot 16, referring to Figure 2 , Figure 3 and Figure 15 , the third locking member 70 is further provided with a second guiding block 701. Correspondingly, a guiding slot 150 for slidably connecting the second guiding block 701 is also provided on the inner housing portion 15.

[0062] In some embodiments, referring to Figure 2 , Figure 8 , Figure 14 and Figure 16 , the electrical connector further includes a tail cover assembly 8. The tail cover assembly 8 is sleeved on the first housing 1. The first housing 1 is provided with a plurality of wire outlet openings 17 communicating with the first cavity 10. The wire outlet openings 17 and the female terminals 2 are correspondingly arranged. The wire outlet openings 17 are used for connecting wires to the female terminals 2. The tail cover assembly 8 includes a detachable first cover portion 80 and a second cover portion 81. The first cover portion 80 and the second cover portion 81 enclose a plurality of limiting openings 82, and the limiting openings 82 communicate with the wire outlet openings 17. The wires can be led out from the wire outlet openings 17 and constrained by the limiting openings 82, improving the sealing performance of the wire leading-out position and providing stable protection for the installation of the wires. It can be understood that the wire outlet openings 17 and the limiting openings 82 can be adaptively adjusted according to the different distributions of the female terminals 2, which will not be elaborated here.

[0063] Referring to Figure 14 and Figure 16 , in this embodiment, one of the first cover portion 80 and the second cover portion 81 is provided with a fifth locking portion 84, and the other is provided with a sixth locking portion 85. The first cover portion 80 and the second cover portion 81 can be hooked to each other through the fifth locking portion 84 and the sixth locking portion 85, so as to quickly fix the two. Multiple pairs of the fifth locking portion 84 and the sixth locking portion 85 can be provided to further improve the stability of the connection between the tail cover assembly 8 and the first housing 1.

[0064] In addition, in order to further quickly dock the first cover portion 80 and the second cover portion 81, in some embodiments, referring to Figure 16 , one of the first cover portion 80 and the second cover portion 81 is provided with an engaging portion 86, and the other is provided with a matching engaging groove 87. When the first cover portion 80 and the second cover portion 81 are docked, they can be engaged with the corresponding engaging groove 87 through the engaging portion 86, so as to further improve the stability of the cooperation between the first cover portion 80 and the second cover portion 81.

[0065] In addition, in some embodiments, referring to Figure 14 andFigure 16 One of the first housing 1 and the end cap assembly 8 is provided with a positioning post 18, and the other is provided with a positioning hole 83 for inserting the positioning post 18.

[0066] In this embodiment, taking the case where the positioning post 18 is provided on the first housing 1 as an example, a plurality of positioning posts 18 are provided on the first housing 1, and a plurality of corresponding positioning holes 83 are respectively provided corresponding to the first cover portion 80 and the second cover portion 81. When the first cover portion 80 and the second cover portion 81 are sleeved on the first housing 1, the stability can be improved through the cooperation of the positioning post 18 and the positioning hole 83.
