Description

Technical Field

[0001] This application relates to the field of automotive connector technology, and more particularly to a male connector and connector assembly. Background Technology

[0002] The primary function of automotive connectors is to enable the transmission of electrical energy and signals between various components in a vehicle's electrical system. They ensure the connection between the power source and electrical equipment, and are also responsible for transmitting digital and analog signals. As automobiles evolve towards intelligence and electrification, connectors play a crucial role in in-vehicle entertainment systems, navigation systems, vehicle networking systems, sensor connections (such as temperature sensors, radar, and cameras), and battery management systems.

[0003] Currently, automotive connectors are often locked together by snap-fit ​​on the male and female ends. However, when the vehicle is in operation, the connector may come loose, causing connection failure and functional problems. Utility Model Content

[0004] This application provides a male connector and connector assembly to solve the problem of connection failure caused by automotive connector tripping.

[0005] Firstly, this application provides a male connector, comprising:

[0006] A housing, the housing including a connecting channel and an injection hole, the connecting channel penetrating the housing, the injection hole being formed in the housing and communicating with the connecting channel; and

[0007] A male connector, wherein the male connector is disposed within the connection channel, and the male connector has a recessed portion;

[0008] The injection hole and the recessed portion are interconnected.

[0009] Secondly, embodiments of this application also provide a male connector, wherein the male connector is used to engage with a female connector, comprising:

[0010] A housing, the housing including a connecting channel extending through the housing;

[0011] A male connector, wherein the male connector is disposed within the connection channel;

[0012] Wherein, the end face of the housing that mates with the female connector is called the insertion surface, the height of the center position of the male connector is E, the height of the insertion surface is Y, and E≤0.5Y.

[0013] Thirdly, this application also provides a connector assembly, including:

[0014] Female connector, the female connector including a socket; and

[0015] As described above, male connector;

[0016] The male connector is inserted into the slot of the female connector.

[0017] The technical solutions provided in this application have the following advantages compared with the prior art:

[0018] The male connector provided in this application embodiment fills the connection channel inside the housing with glue through the injection hole. Since the injection hole and the recessed part are connected, the glue injected into the connection channel through the injection hole will flow directly to the recessed part. The glue-filling structure connects the housing and the male connector, making the connection between the housing and the male connector more stable, increasing the connection strength between the housing and the male connector, and effectively avoiding the problem of connector disengagement and connection failure during vehicle operation.

[0101] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0102] The following disclosure provides numerous different embodiments or examples for implementing various structures of the present invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0103] For ease of description, spatial relative terms may be used in the text to describe the relative position or movement of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "front," "back," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure undergoes a positional flip, orientation change, or change of motion, these directional indications will change accordingly. For instance, an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0104] like Figures 1 to 16 As shown, this application provides a housing for a female connector. At least as Figure 1 and Figure 13 As shown, in this embodiment, the outer cover 11 is used for an automotive connector. The outer cover 11 has a mating slot 111, and a retaining structure 115 is provided on the bottom of the slot 111. The retaining structure 115 extends along a first direction a1 (e.g., the insertion direction), such as... Figure 3 The slot 111 is configured to be inserted into the male connector 2, and the retaining structure 115 is embedded and engaged with the male connector 2 in the first direction a1.

[0105] At least as Figure 5 and Figure 17 As shown, in this embodiment, the female connector 13 of the female connector 1 is disposed in the slot 111, the slot 111 is configured to be inserted into the housing 21 of the male connector 2, the housing 21 is provided with a male connector 23, the male connector 23 is inserted into the female connector 13; the housing 21 is provided with a mating structure 211, the mating structure 211 is embedded in the retaining structure 115 in the first direction a1.

[0106] When the female connector 1 and the male connector 2 are inserted and mated, the housing 21 moves along the first direction a1, thereby inserting into the mating slot 111 of the outer cover 11. During the insertion process, the retaining structure 115 on the outer cover 11 and the mating structure 211 on the housing 21 are interlocked to achieve positioning, guiding, and supporting functions. Figure 16 After insertion, the male connector 23 on the housing 21 is inserted into the female connector 13 on the outer cover 11, thereby achieving electrical connection and signal transmission, such as... Figure 15 .

[0107] At least as Figure 3 and Figure 17 As shown, in this embodiment, the retaining structure 115 is disposed in the slot 111. The retaining structure 115 extends along the first direction a1 to ensure the insertion depth of the housing 21 relative to the outer cover 11, so that the connection strength can be ensured after the two are docked.

[0108] At least as Figure 5 and Figure 17 As shown, in some embodiments, the female connector 13 is disposed within the outer casing 11 and within the mating slot 111. Under normal circumstances, after the female connector 13 and the male connector 23 are inserted and mated, if the entire device shakes, the female connector 13 and the male connector 23 may experience damage, breakage, or loosening at the connection point. However, the fixing structure 115 reduces the shaking of the housing 21 and the outer casing 11, minimizing the impact on the female connector 13 and the male connector 23, thus solving the problem of potential damage, breakage, or loosening at the connection point. Figure 15 and Figure 16 .

[0109] At least as Figure 1As shown, in some embodiments, in order to further improve the support effect of the holding structure 115, the holding structure 115 is integrally formed on the outer cover 11.

[0110] At least as Figure 1 , Figures 14 to 17 As shown, in some embodiments, the retaining structure 115 includes a support member 1151, which extends along a second direction a2 (e.g., the width direction), perpendicular to the first direction a1. In this embodiment, a guide portion 11511 is formed on the support member 1151; the mating structure 211 includes a first groove structure 2111, which is configured to fit into the support member 1151 to achieve a supporting effect. The guide portion 11511 guides the support member 1151 during its fitting with the first groove structure 2111, making the mating of the female connector 13 and the male connector 23 smoother and reducing interference and collisions between components during assembly. Furthermore, by extending the support member 1151 along the second direction a2, the size of the support member 1151 can be maximized within the limited space of the mating slot 111, further enhancing the connection strength between the retaining structure 115 and the mating structure 211.

[0111] At least as Figures 1 to 6 As shown, in some embodiments, the support member 1151 can be elongated, U-shaped, inverted U-shaped, or U-shaped from the perspective of the first direction a1. When the support member 1151 is elongated, the female end connector 13 can be located on one side of the support member 1151 in a third direction a3 (e.g., the height direction), wherein the third direction a3, the second direction a2, and the first direction a1 are perpendicular to each other, that is, the female end connector 13 is located above or below the support member 1151. When the support member 1151 is U-shaped or inverted U-shaped, the female end connector 13 can be disposed on the side facing the opening of the support member 1151, or on the side away from the opening of the support member 1151. Similarly, when the support member 1151 is U-shaped, the female end connector 13 can be disposed inside the U-shape of the support member 1151, or outside the U-shape of the support member 1151. When the support member 1151 is of other shapes, the setting position of the female end connector 13 can be deduced similarly, and will not be described again.

[0112] Since the shape of the support member 1151 can be set to different shapes, in some embodiments, the support member 1151 covers at least part of the female end connector 13, so that the support member 1151 can protect the female end connector 13 and improve the connection strength during the insertion process.

[0113] At least as Figure 6 As shown, in some embodiments, the length of the support member 1151 in the second direction a2 is C, and the length of the female end connector 13 in the second direction a2 is X, where C = (1.5... ～ 1.8)X, that is, C can be between 1.5 and 1.8 times X. In some embodiments, C can be 1.5, 1.6, 1.7, or 1.8 times X. By setting the length of the support member 1151 to be greater than the length of the female connector 13, the support member 1151 is ensured to provide more stable mechanical support, reducing the swaying of the female connector 13 under vibration or impact, thereby improving the overall stability of the female connector 1.

[0114] At least as Figure 1 , Figures 15 to 17 As shown, in some embodiments, the retaining structure 115 includes a guide member 1152 or a guide hole. When the retaining structure 115 includes a guide member 1152, the docking structure 211 includes a second groove structure 2113 formed on the housing 21. The guide member 1152 is embedded in the second groove structure 2113 to achieve the embedded engagement between the retaining structure 115 and the docking structure 211. In some embodiments, the guide member 1152 can be replaced with a guide hole, and the second groove structure 2113 can be replaced with a guide member formed on the housing 21. The guide member is embedded in the guide hole to achieve the embedded engagement between the retaining structure 115 and the docking structure 211. In this embodiment, the retaining structure 115 is used as an example to describe the guide member 1152. Furthermore, this embodiment does not limit the shape of the guide member 1152 from the perspective of the first direction a1; the shape of the guide member 1152 can be circular, rectangular, or rhomboid, etc. In some embodiments, to ensure the supporting connection effect, multiple guide members 1152 may be provided. Additionally, in some embodiments, the guide member 1152 can be a block-shaped or columnar structure.

[0115] In some embodiments, the guide member 1152 may also be provided with rounded corners or chamfers at each corner. Rounded corners or chamfers can effectively disperse stress and avoid stress concentration caused by sharp edges. In the embedded fit, the design of rounded corners or chamfers can reduce the risk of deformation or cracking of the guide member 1152 due to stress concentration during machining, assembly and use.

[0116] At least as Figure 1 and Figure 16As shown, in some embodiments, the retaining structure 115 includes both a support member 1151 and a guide member 1152, with the guide member 1152 and the support member 1151 spaced apart along a third direction a3; the docking structure 211 includes both a first groove structure 2111 and a second groove structure 2113, the first groove structure 2111 being configured to engage with the support member 1151, and the second groove structure 2113 being configured to engage with the guide member 1152. The guide member 1152, in coordination with the support member 1151, further enhances the connection strength between the outer cover 11 and the housing 21.

[0117] In some embodiments, the structure of the guide member 1152 may be the same as that of the support member 1151, with the increased number of guide members enhancing the connection strength between the outer cover 11 and the housing 21. In some embodiments, the structure of the guide member 1152 may also differ from that of the support member 1151. For example, the support member 1151 may be a strip-shaped structure, while the guide member 1152 may be a block-shaped structure, which increases the connection strength and also prevents misalignment. In some embodiments, the strip-shaped structure includes, but is not limited to, rectangular or rounded rectangular shapes, and the block-shaped structure includes, but is not limited to, circular or square block structures.

[0118] At least as Figure 1 , Figure 2 and Figure 13 As shown, in some embodiments, the support member 1151 extends along the second direction a2, and the guide member 1152 is distributed at intervals with the support member 1151 along the third direction a3, thereby strengthening the connection between the outer cover 11 and the housing 21 in both the second direction a2 and the third direction a3.

[0119] In some embodiments, at least two guide members 1152 are provided, and the two guide members 1152 are spaced apart along the second direction a2. The guide portions 11511 are formed at both ends of the support member 1151; wherein each guide member 1152 and each guide portion 11511 are aligned. By providing two guide members 1152 to symmetrically distribute stress, and aligning the two guide members 1152 with the ends of the support member 1151 respectively, the balance of the relevant holding forces after the outer cover 11 and the housing 21 are connected is ensured.

[0120] At least as Figure 6 As shown, in some embodiments, in the second direction a2, the length of the support 1151 is C, and the farthest distance between the two guides 1152 is D, where D = (1.02) / 2. ～1.15)C, that is, D can be between 1.02 and 1.15 times C. In some embodiments, D can be 1.02, 1.03, 1.04, 1.05, 1.06, 1.07, 1.08, 1.09, 1.10, 1.11, 1.12, 1.13, 1.14, or 1.15 times C. By setting the furthest distance between the two guides 1152 to be different from the length of the support 1151, the accuracy of mating can be better guided during the insertion process with the male connector 2, which helps to reduce the error during mating and improve the reliability and stability of the connection.

[0121] Furthermore, in some embodiments, the furthest distance between the two guides 1152 is slightly greater than the length of the support 1151, thereby increasing the width of the connection between the retaining structure 115 and the docking structure 211, thus providing higher mechanical strength, reducing deformation or damage in vibration and shock environments, and also providing better electrical isolation and signal integrity to meet higher performance requirements; and reducing costs while ensuring higher mechanical strength.

[0122] At least as Figures 5 to 7 As shown, in some embodiments, the height of the center position of the female connector 13 is A, and the height of the outer cover 11 is H, where A ≤ 0.5H, that is, A is less than or equal to 0.5 times H. In some embodiments, A can be 0.1 times, 0.15 times, 0.2 times, 0.25 times, 0.3 times, 0.35 times, 0.4 times, 0.45 times, or 0.5 times H. By setting the center position of the female connector 13 at 0.5 times or less than the height of the outer cover 11, and installing the female connector 13 in the middle or below the middle of the outer cover 11, the center of gravity of the female connector 1 can be lowered, thereby improving the overall mechanical stability; it can also reduce the shaking caused by vehicle vibration or impact, ensuring the reliability of the female connector 1 under complex working conditions. In addition, the lower installation position can disperse the mechanical stress transmitted by the outer cover 11, reduce the impact of stress concentration on the female connector 13, and help extend the service life of the female connector 1. Especially during long-term use, it can effectively reduce damage caused by stress fatigue.

[0123] In addition, by setting the center position of the female end connector 13 at the middle or below the height of the outer cover 11, a reasonable layout can be made inside the outer cover 11. By arranging the female end connector 13 in the middle or lower area of ​​the outer cover 11, the space above the female end connector 13 can be expanded, and the components located inside the outer cover 11 can be reasonably arranged, thereby improving space utilization.

[0124] At least as Figures 5 to 7 As shown, in some embodiments, the height of the center position of the female connector 13 is A, and the height of the outer cover 11 is H, where A ≤ 0.4H, that is, A is less than or equal to 0.4 times H. In some embodiments, A can be 0.1 times, 0.15 times, 0.2 times, 0.25 times, 0.3 times, 0.35 times, or 0.4 times H. By further lowering the center of gravity of the female connector 1, its overall mechanical stability is improved. The lower installation position allows for better utilization of the protective function of the outer cover 11, reducing the entry of dust, moisture, and other contaminants into the interior of the female connector 13, which helps to improve the electrical performance and service life of the female connector 13.

[0125] At least as Figures 5 to 7 As shown, in some embodiments, the height of the center position of the female connector 13 is A, and the height of the outer cover 11 is H, where A ≤ 0.3H, that is, A is less than or equal to 0.3 times H. In some embodiments, A can be 0.1 times, 0.15 times, 0.2 times, 0.25 times, or 0.3 times H. While further lowering the center of gravity of the female connector 1 and further improving the overall mechanical stability, the lower installation position also facilitates assembly and maintenance, reduces interference with the internal structure during assembly, and facilitates quick inspection and replacement of relevant components when needed.

[0126] At least as Figures 5 to 7 As shown, in some embodiments, the height of the center position of the female connector 13 is A, and the height of the outer cover 11 is H, where A = (0.1) / H. ～ 0.3)H, that is, A can be between 0.1 and 0.3 times H. In some embodiments, A can be 0.1, 0.15, 0.2, 0.25, or 0.3 times H. In this embodiment, the female connector 13 is positioned with its center located between 0.1 and 0.3 times the height of the outer cover 11, thereby ensuring that the female connector 13 is at the lowest possible height on the outer cover 11, thus ensuring that the electrical clearance and creepage distance of the female connector 13 meet the design requirements and avoiding short circuits or electrical breakdowns.

[0127] At least as Figure 6 and Figure 7 As shown, in some embodiments, the height of the lowest point of the female connector 13 is B, where B > 0.15 mm. This further ensures the electrical clearance and creepage distance of the female connector 13, guaranteeing safety and reliability.

[0128] At least as Figure 6 and Figure 7As shown, in some embodiments, the support member 1151 of the retaining structure 115 is located at the middle of the outer cover 11, the guide member 1152 of the retaining structure 115 is located above the support member 1151, and the female end connector 13 is located below the support member 1151; the female end connector 13 is located below the middle of the outer cover 11, and the retaining structure 115 is located at the middle and above the middle of the outer cover 11. After the female end connector 13 and the male end connector 23 are inserted and engaged, as... Figure 15 and Figure 16 By interlocking the retaining structure 115 of the outer cover 11 with the mating structure 211 of the housing 21, a portion of the weight of the housing 21 can be transferred to the outer cover 11 during use and assembly. In other words, the outer cover 11 bears a portion of the weight of the housing 21, reducing the problem of uneven force distribution at the upper and lower contact points during connector mating, which could lead to inaccurate matching of functions at the contact points. Furthermore, this arrangement allows for better space utilization within the mating slot 111 of the outer cover 11, offering advantages in versatility and enhanced functionality.

[0129] Furthermore, the setting of the retaining structure 115 on the outer cover 11 in this embodiment does not affect the characteristics of the female connector 13, which can meet the requirements for mating with male connectors 2 of different product heights and specifications, ensuring the scope of use. That is to say, the female connector 13 can be selected with appropriate specifications according to actual usage needs, and the corresponding male connector 2 can be selected for mating.

[0130] At least as Figure 1 and Figure 3 As shown, in some embodiments, the length of the support member 1151 in the first direction a1 is greater than or equal to half the length of the slot 111 in the first direction a1, the support member 1151 extends in the second direction a2, and by setting the length of the support member 1151 in the first direction a1 to be longer, the connection effect between the outer cover 11 and the housing 21 can be guaranteed.

[0131] At least as Figure 3 and Figure 16As shown, in some embodiments, the length of the guide member 1152 in the first direction a1 is less than or equal to the length of the support member 1151 in the first direction a1. This can improve the connection strength based on the support member 1151 and also reduce costs. Furthermore, the length of the guide member 1152 in the first direction a1 is greater than or equal to half the length of the support member 1151 in the first direction a1, which can ensure connection strength after the guide member 1152 is assembled. In addition, by setting the length of the support member 1151 in the first direction a1 to be different from the length of the guide member 1152 in the first direction a1, the assembly time of each component can be staggered during the assembly of the outer cover 11 and the housing 21, avoiding the problems of high alignment difficulty and long alignment time caused by simultaneously aligning multiple components. Furthermore, when multiple components need to be assembled simultaneously, the connection accuracy between the components will decrease, and the reliability of the assembled connection will also decrease. This device, however, can improve connection accuracy and efficiency while achieving orderly assembly.

[0132] At least as Figure 2 and Figure 13 As shown, in some embodiments, the slot 111 has two inner sidewalls 112 arranged opposite to each other, and at least one positioning structure is provided on the inner sidewall 112. The positioning structure includes a positioning groove 116 or a positioning block, and the positioning structure is configured to play a positioning role when the outer cover 11 is connected to the housing 21.

[0133] At least as Figure 2 , Figure 5 and Figure 17 As shown, in this embodiment, taking the positioning groove 116 as an example, when the positioning structure is the positioning groove 116, the housing 21 is provided with a positioning block 212 at the corresponding position of the positioning groove 116. The positioning connection is achieved through the interlocking and cooperation of the positioning groove 116 and the positioning block 212. In other embodiments, when the positioning structure is a positioning block, the housing 21 is provided with a positioning groove at the corresponding position of the positioning block. The positioning connection is achieved through the interlocking and cooperation of the positioning block and the positioning groove.

[0134] At least as Figure 2 , Figure 5 and Figure 17As shown, in this embodiment, the positioning structure on the outer cover 11 adopts a positioning groove 116. The positioning structure has at least one such groove, so at least one positioning block 212 is provided on each of the opposite sides of the housing 21. A positioning guide 2121 is formed at the end of each positioning block 212, and the positioning guide 2121 is configured to insert into the positioning groove 116 of the female connector 1. The positioning guide 2121 is configured to guide the insertion of the positioning block 212 into the positioning groove 116, and also facilitates injection molding.

[0135] At least as Figure 17 As shown, in some embodiments, the positioning guide 2121 includes a rounded corner structure or a chamfered structure to achieve a guiding function. The rounded corner structure includes a full rounded corner structure and a semi-rounded corner structure. In this embodiment, the positioning guide 2121 adopts a full rounded corner structure, meaning that the shape of the positioning guide 2121 is semi-circular when viewed from the second direction a2. This is beneficial for injection molding and allows for automatic alignment during the insertion process.

[0136] At least as Figure 2 and Figure 17 As shown, in some embodiments, the positioning structure may be provided in two or more to improve the positioning effect. In this embodiment, the inner sidewall 112 is provided with two positioning grooves 116, and the housing 21 is provided with two positioning blocks 212 at intervals on the same side.

[0137] In some embodiments, the positioning structures on the two inner sidewalls 112 can be symmetrically arranged, which facilitates production and preparation while achieving the positioning effect. Figure 2 In some embodiments, the positioning structures on the two inner sidewalls 112 may also be staggered to achieve a foolproof effect.

[0138] At least as Figure 1 and Figure 2 As shown, in some embodiments, among the positioning structures on the inner sidewall 112, at least one positioning structure has a different size from the other positioning structures in the first direction a1. The different sizes include different shapes, different areas, etc. The positioning structures with different structures can not only achieve the positioning effect, but also the error prevention effect.

[0139] At least as Figure 2 and Figure 6As shown, in some embodiments, the outer cover 11 has two outer side walls 114, which are aligned with two inner side walls 112. In the second direction a2, the length between the inner side wall 112 and its corresponding outer side wall 114 is R, and the length of the positioning structure is P, where P ≥ R / 2, that is, P is greater than or equal to half of R. By setting the length of the positioning structure in the second direction a2 to be greater than or equal to half the thickness of the wall surface where the positioning structure is located, a more stable docking effect can be ensured. In some embodiments, R is 2 mm and P is 1 mm.

[0140] At least as Figure 2 and Figure 17 As shown, in some embodiments, an inner top wall 113 connects the two inner sidewalls 112. A through groove 117 is provided on both the inner sidewall 112 and the inner top wall 113, or both the inner sidewall 112 and the inner top wall 113 may have through grooves 117. In other embodiments, the through groove 117 may be provided only on the inner sidewall 112 or only on the inner top wall 113. The through groove 117 effectively avoids deformation caused by excessive plastic wall thickness and area during the manufacturing process, preventing proper matching with the housing 21. Simultaneously, the through groove 117 can also provide venting, ensuring smooth demolding during manufacturing and guaranteeing the reliability of production.

[0141] like Figures 8 to 12 As shown, in some embodiments, the female connector 1 includes a joining member 17 configured to connect the outer cover 11 and the female connector 13. The female connector 13 can be assembled onto the outer cover 11 and then electrically connected to the circuit board.

[0142] like Figure 8 and Figure 9As shown, in some embodiments, the joining component 17 includes a first joining member 171 and a second joining member 173, wherein the first joining member 171 is aligned with the head of the female end connector 13, and the second joining member 173 is aligned with the tail of the female end connector 13; the outer cover 11 is provided with a first joining hole 118 and a second joining hole 119, the first joining hole 118 being configured to engage with the first joining member 171, and the second joining hole 119 being configured to engage with the second joining member 173. Therefore, after the female end connector 13 is assembled onto the outer cover 11 under the action of the joining component 17, the positional reliability of the female end connector 13 can be ensured, preventing the head of the female end connector 13 from sinking. Furthermore, since the female connector 13 needs to be connected to the circuit board after being assembled to the outer cover 11, the setting of the joining component 17 eliminates the need for additional auxiliary structures when connecting to the circuit board to avoid misalignment of the female connector 13. The joining component 17 also facilitates the operation with the circuit board.

[0143] The first coupling member 171 includes a first bent portion 1711 and a first extension portion 1713 connected at an angle, and the second coupling member 173 includes a second bent portion 1731 and a second extension portion 1733 connected at an angle; the extension direction of the first extension portion 1713 is the same as or perpendicular to the extension direction of the second extension portion 1733. Wherein, when the extension direction of the first extension portion 1713 is the same as the extension direction of the second extension portion 1733, the first coupling hole 118 and the second coupling hole 119 can communicate with each other, such as... Figures 10 to 12 As shown.

[0144] Furthermore, the engaging member 17 can have various configurations, which are described below. For example... Figure 9 As shown, in some embodiments, the female connector 13 includes a female connector shell 131 and a female connector body 133. The female connector body 133 is disposed within the female connector shell 131, and the engaging member 17 is disposed on the female connector shell 131, thereby connecting the female connector 13 to the outer cover 11. In this embodiment, the engaging member 17 and the female connector shell 131 are integrally formed, which reduces material costs and weight.

[0145] like Figure 10 As shown, in some embodiments, the female connector 1 includes an auxiliary housing 15, the female connector 13 includes a female connector shell 131 and a female connector body 133, and the first connector 171 and the second connector 173 in the connecting member 17 can be simultaneously disposed on the female connector shell 131. Figure 11As shown, in some embodiments, the first coupling member 171 and the second coupling member 173 of the coupling member 17 may also be simultaneously disposed on the auxiliary housing 15. For example... Figure 12 As shown, in some embodiments, one of the first connector 171 and the second connector 173 may be disposed on the auxiliary housing 15, and the other may be disposed on the female end connector 131. In some embodiments, the female end connector 13 is fixed in the auxiliary housing 15, for example, the female end connector 13 and the auxiliary housing 15 may be fixed by laser welding.

[0146] In addition, such as Figure 11 As shown, in some embodiments, the female connector 13 is disposed inside the auxiliary housing 15, and the connecting member 17 is disposed on the auxiliary housing 15 to connect the auxiliary housing 15 and the outer cover 11, thereby connecting the female connector 13 to the outer cover 11.

[0147] In other embodiments, the female connector 1 may not have a mating part 17. In this case, the female connector 13 can be assembled onto the circuit board first, and then the outer cover 11 can be placed on the female connector 13.

[0148] like Figures 8 to 12 As shown, in some embodiments, the female connector 1 includes guide members 19, two of which are spaced apart along a second direction a2, and the guide members 19 extend along a first direction a1. In some embodiments, the guide members 19 are disposed on the auxiliary housing 15, and one end of the guide member 19 near the head of the female connector 13 is connected to the auxiliary housing 15 by a rounded corner transition, such as... Figures 10 to 12 As shown; in some embodiments, the guide member 19 may also be disposed on the female end connecting shell 131, and the end of the guide member 19 near the head of the female end connector 13 is connected to the female end connecting shell 131 by a rounded transition, such as... Figure 9 As shown. In the above embodiment, the rounded corners serve a guiding function.

[0149] like Figure 9 As shown, in some embodiments, the guide member 19 is integrally formed onto the female end connecting shell 131. For example... Figures 10 to 12 As shown, in some embodiments, the guide member 19 is integrally formed on the auxiliary housing 15. In some embodiments, the guide member may also be integrally formed on the support member 1151, which extends along a third direction a3 to form the guide member described above, with the two guide members located on opposite sides of the female end connector 13 in the second direction a2. Figure 46 As shown, in some embodiments, after the guide component 19 is integrally formed onto the support member 1151, the whole can form an inverted U-shaped structure. The guide component 19 serves a guiding function during the insertion process.

[0150] like Figure 6 As shown, in some embodiments, in the second direction a2, the minimum distance between the support member 1151 of the retaining structure 115 and the inner wall 112 of the opposite outer cover 11 is K, and the minimum distance between the guide member 19 and the inner wall 112 of the opposite outer cover 11 is M, where K = (0.3) / M. ～ 0.5)M, that is, K can be between 0.3 and 0.5 times M. In some embodiments, K can be 0.3, 0.35, 0.4, 0.45, or 0.5 times M. In some embodiments, K is 1.2 mm and M is 3.1 mm.

[0151] like Figure 13 As shown, this application also provides a connector assembly, including a male connector 2 and a female connector 1, wherein the male connector 2 is engaged with the female connector 1.

[0152] like Figures 13 to 46 As shown, this application provides a male connector 2. At least as Figures 17 to 36 As shown, in this embodiment, the male connector 2 includes a housing 21 and a male connector 23. A connecting channel 213 is formed through the interior of the housing 21, and an injection hole 214 is formed on the housing 21, connecting the connecting channel 213 to the outside. The male connector 23 is disposed within the connecting channel 213, and a recess B2 is formed on the male connector 23. The injection hole 214 is aligned with and communicates with the recess B2.

[0153] like Figure 19 and Figure 37 As shown, in this embodiment, the male connector 23 is first placed inside the connection channel 213, and then glue is injected into the connection channel 213 inside the housing 21 through the injection hole 214. Since the injection hole 214 is connected to the recessed portion B2, the glue injected into the connection channel 213 through the injection hole 214 will flow directly to the recessed portion B2. After the glue cures, a potting structure 25 is formed. The potting structure 25 connects the housing 21 and the male connector 23, making the connection between the housing 21 and the male connector 23 more stable, increasing the connection strength between the housing 21 and the male connector 23, and effectively avoiding the problem of connector disengagement and connection failure during vehicle operation.

[0154] In some embodiments, the male connector 23 may be arranged in an I-shaped or similar structure when viewed from a side view (e.g., along the second direction a2) or a top view (e.g., along the third direction a3). The housing 21 covers the outer periphery of the male connector 23 and can protect the male connector 23.

[0155] At least as Figure 19 , Figure 30 as well as Figure 36 As shown, in some embodiments, the potting structure 25 is potted and molded into the injection hole 214 and the recess B2. The potting structure 25 includes a main body 251 and at least one protrusion 253. The main body 251 is formed at the recess B2, and each of the protrusions 253 is aligned and formed within each of the injection holes 214. The protrusions 253 hold the housing 21 in place, and the main body 251 holds the male connector 23 in place, thereby ensuring the connection effect after potting.

[0156] At least as Figure 13 , Figure 19 as well as Figure 30 As shown, in some embodiments, the male connector 23 includes an insulator 231 and a male connector body 233; the male connector body 233 is embedded in the insulator 231, and one end of the male connector body 233 protrudes from the insulator 231 and is configured to plug into the female connector body 133 of the female connector 1; the other end of the male connector 23 is connected to a cable 27.

[0157] At least as Figure 30 As shown, in some embodiments, the insulator 231 includes a first insulating portion 2311 and a second insulating portion 2313, which are arranged in a stepped shape; the end of the male terminal connecting body 233 protrudes from the first insulating portion 2311; the stepped structure ensures connection strength while reducing cost.

[0158] At least as Figure 31 and Figure 32 As shown, in some embodiments, the second insulating portion 2313 includes a first insulating segment 2313A, a second insulating segment 2313B, and a third insulating segment 2313C, with the second insulating segment 2313B disposed between the first insulating segment 2313A and the third insulating segment 2313C. The first insulating segment 2313A has a first insulating segment outer surface A1, the second insulating segment 2313B has a second insulating segment outer surface B1, and the third insulating segment 2313C has a third insulating segment outer surface C1.

[0159] At least as Figure 31 , Figure 32 and Figures 35 to 37 As shown, in some embodiments, the second insulating segment 2313B includes a recess B2, meaning the recess B2 is disposed on the second insulating segment 2313. The recess B2 has two spaced-apart sidewalls B21, with a bottom surface B22 connecting the two sidewalls B21. The top end of one sidewall B21 connects to the outer surface A1 of the first insulating segment, and the top end of the other sidewall B21 connects to the outer surface C1 of the third insulating segment. The top end of the sidewall B21 refers to the end of the sidewall B21 away from the center of the second insulating segment 2313. The bottom ends of the two sidewalls B21 connect to the bottom surface B22, and the bottom ends of the sidewalls B21 refer to the ends of the sidewalls B21 closer to the center of the second insulating segment 2313. After potting, the potting structure 25 fills the recess B2, achieving a fixed connection between the male connector 23 and the housing 21.

[0160] At least as Figure 16 , Figure 29 , Figure 36 and Figure 44 As shown, in this embodiment, the two sidewalls B21 can act as a barrier during glue pouring, effectively preventing the glue from flowing freely inside the connection channel 213 and affecting other components of the male connector 2.

[0161] At least as Figures 31 to 37 As shown, in some embodiments, the recess B2 surrounds the second insulating segment 2313B in the circumferential direction, and the second insulating segment 2313B has at least one second insulating segment outer surface B1; when the shape of the recess B2 in the cross section perpendicular to the first direction a1 is U-shaped, the second insulating segment 2313B has one second insulating segment outer surface B1, two ends of the second insulating segment outer surface B1 are coplanar with the first insulating segment outer surface A1 and the third insulating segment outer surface C1 respectively, and the other two ends of the second insulating segment outer surface B1 are connected to the two ends of the bottom surface B22 respectively.

[0162] In some embodiments, one end of the outer surface B1 of the second insulating segment is coplanar with the outer surface A1 of the first insulating segment, and the other end of the outer surface B1 of the second insulating segment forms a step difference with the outer surface C1 of the third insulating segment.

[0163] In some embodiments, one end of the outer surface B1 of the second insulating segment is coplanar with the outer surface C1 of the third insulating segment, and the other end of the outer surface B1 of the second insulating segment forms a step difference with the outer surface A1 of the first insulating segment.

[0164] In some embodiments, when the concave portion B2 is U-shaped in a cross section perpendicular to the first direction a1, the two vertical sides of the U-shape have different heights. The second insulating segment 2313B has two outer surfaces B1 of the second insulating segment connected at an angle. The two outer surfaces B1 of the second insulating segment connected at an angle are in the shape of an inverted L-shape in the cross section of the first direction a1. The inverted L-shape and the aforementioned U-shape are combined to form a ring.

[0165] In some embodiments, when the concave portion B2 is U-shaped in a cross section perpendicular to the first direction a1, the two vertical sides of the U-shape are at the same or different heights. The second insulating segment 2313B has three outer surfaces B1 of the second insulating segment connected at an angle. The three outer surfaces B1 of the second insulating segment connected at an angle are in the shape of an inverted U-shape in a cross section of the first direction a1. The two vertical sides of the inverted U-shape are at the same or different heights. The inverted U-shape and the aforementioned U-shape are joined together to form a ring.

[0166] At least as Figures 38 to 42 As shown, in some embodiments, the recessed portion B2 completely surrounds the second insulating segment 2313B circumferentially, and the recessed portion B2 has an annular shape in a cross-section perpendicular to the first direction a1, such as... Figure 42 After potting, the potting structure 25 fills the recessed portion B2, and the potting structure 25 completely covers the second insulating segment 2313B, improving the connection effect between the second insulating segment 2313B and the housing 21, and ensuring the overall connection strength.

[0167] In some embodiments, the shape of the recessed portion B2 in the cross section perpendicular to the first direction a1 can also be L-shaped or elongated, that is, in this case, there can be multiple recessed portions B2. After potting, the potting structure 25 fills these multiple recessed portions B2 and connects the male connector 23 and the housing 21.

[0168] At least as Figure 34 and Figure 36 As shown, in some embodiments, the length of the first insulating segment 2313A is Q, and the length of the third insulating segment 2313C is Z, where Q = (0.8... ～1.2) Z, that is, Q can be between 0.8 and 1.2 times Z. In some embodiments, Q can be 0.8, 0.9, 1.0, 1.1, or 1.2 times Z. This ensures the opening position of the recessed portion B2, ensures the stable opening of the recessed portion B2, and also ensures the overall strength of the second insulating portion 2313.

[0169] At least as Figure 23 and Figure 34 As shown, in some embodiments, the length of the second insulating segment 2313B is N, and the total length of the second insulating portion 2313 is W, where N = (0.1... ～ 0.5)W, that is, N can be between 0.1 and 0.5 times W. In some embodiments, N can be 0.1, 0.2, 0.3, 0.4, or 0.5 times W. By ensuring the length of the second insulating segment 2313B, the length of the recessed portion B2 is also ensured, thereby ensuring the bonding force and bending resistance between the potting structure 25 and the housing 21 and the male connector 23.

[0170] At least as Figure 19 , Figure 22 , Figure 33 as well as Figure 45 As shown, in some embodiments, the male connector 23 may also have an auxiliary hole 2313D. The auxiliary hole 2313D, the recessed portion B2, and the injection hole 214 are interconnected. After the housing 21 and the male connector 23 are glued together, one of the protrusions 253 fills the auxiliary hole 2313D, the main body 251 fills the recessed portion B2, and one of the protrusions 253 fills the injection hole 214, further enhancing the connection strength between the housing 21 and the male connector 23. In this embodiment, the auxiliary hole 2313D is located in the second insulating section 2313B.

[0171] In some embodiments, two or more auxiliary holes 2313D are provided to improve the connection strength; after the housing 21 and the male connector 23 are connected by potting, each auxiliary hole 2313D is filled with the protrusion 253.

[0172] At least as Figure 19 and Figure 34As shown, in some embodiments, two or more injection holes 214 are spaced apart. When there are two or more injection holes 214, each injection hole 214 can be used for simultaneous glue filling, improving glue filling efficiency. In other embodiments, some injection holes 214 can be configured for glue filling, while others can be configured for venting. Venting can effectively remove air bubbles in the glue, preventing defects such as local depressions, pinholes, and cracks after curing. Venting can also ensure the sealing and insulation after glue filling, avoiding poor sealing or decreased electrical performance caused by air bubbles. Furthermore, by setting two or more injection holes 214, the connection strength between the housing 21 and the male connector 23 can be further improved.

[0173] At least as Figure 19 , Figures 25 to 29 As shown, in some embodiments, the housing 21 has an outer surface 216, and each of the injection holes 214 is formed on the same surface of the outer surface 216. For example, such as... Figure 19 As shown, the outer surface 216 of the housing has a lower surface in the third direction a3, and each of the injection holes 214 is opened on the lower surface to facilitate the preparation of the injection holes 214 and the injection of adhesive.

[0174] In other embodiments, each of the injection holes 214 is respectively opened on two different surfaces of the outer surface 216 of the housing. For example, the outer surface 216 of the housing has a left side surface and a right side surface that are oppositely arranged in the second direction a2, and each of the injection holes 214 is respectively opened on the left side surface and the right side surface to ensure connection strength.

[0175] At least as Figure 24 and Figure 25 As shown, in some embodiments, the outer surface 216 of the housing has an upper surface and a lower surface that are disposed opposite to each other in the third direction a3, and each of the injection holes 214 is respectively opened on the upper surface and the lower surface, which can improve the connection strength between the housing 21 and the male end connector 23.

[0176] At least as Figure 13 , Figures 19 to 21As shown, in some embodiments, the housing 21 is configured such that the end face that mates with the female connector 1 is a mating surface 215. The height of the center position of the male connector 23 is E, and the height of the mating surface 215 is Y, where E ≤ 0.5Y, that is, E is less than or equal to 0.5 times Y. In some embodiments, E can be 0.1 times, 0.15 times, 0.2 times, 0.25 times, 0.3 times, 0.35 times, 0.4 times, 0.45 times, or 0.5 times Y. By setting the center position of the male connector 23 to 0.5 times or less of the height of the mating surface 215, the center of gravity of the male connector 2 can be lowered, thereby improving the overall mechanical stability and reducing swaying caused by vehicle vibration or impact, ensuring the reliability of the male connector 2 under complex working conditions.

[0177] At least as Figure 13 , Figures 19 to 21 As shown, in some embodiments, the height of the center position of the male connector 23 is E, and the height of the mating surface 215 is Y, where E ≤ 0.4Y, that is, E is less than or equal to 0.4 times Y. In some embodiments, E can be 0.1 times, 0.15 times, 0.2 times, 0.25 times, 0.3 times, 0.35 times, or 0.4 times Y. This further lowers the center of gravity of the male connector 2, thereby improving its overall mechanical stability. In addition, the lower mounting position can disperse the mechanical stress transmitted by the housing 21, reduce the impact of stress concentration on the male connector 23, and help extend the service life of the male connector 2, especially during long-term use, effectively reducing damage caused by stress fatigue.

[0178] At least as Figure 13 , Figures 19 to 21 As shown, in some embodiments, the height of the center position of the male connector 23 is E, and the height of the insertion surface 215 is Y, where E = (0.1... ～ 0.3)Y, that is, E can be between 0.1 and 0.3 of Y. In some embodiments, E can be 0.1 times, 0.15 times, 0.2 times, 0.25 times, or 0.3 times Y. In this embodiment, the male connector 23 is positioned with its center located between 0.1 times and 0.3 times the height of the insertion surface 215 of the housing 21, ensuring the minimum height of the male connector 23 relative to the insertion surface 215 of the housing 21, thereby ensuring that the electrical clearance and creepage distance of the male connector 23 meet the design requirements and avoid short circuits or electrical breakdowns.

[0179] At least as Figure 20 and Figure 23As shown, in some embodiments, the height of the lowest point of the male connector 23 is F, where F > 0.15 mm. This further ensures the electrical clearance and creepage distance of the male connector 23, guaranteeing safety and reliability. It should be noted that the relevant heights of the male connector 23 mentioned above (e.g., the heights E and F mentioned above) are compared with the insertion surface 215 as a reference.

[0180] At least as Figure 13 , Figure 26 as well as Figure 27 As shown, in some embodiments, in each of the outer surfaces 216 of the housing, the circumferential surface of the housing 21 that is configured to be mated with the female connector 1 is a mating surface 2161. An extension groove 217 is provided on each of the opposite sides of the housing 21. The extension groove 217 is provided on the mating surface 2161 of the housing 21 and extends along the insertion direction of the housing 21. The extension groove 217 can reduce the contact area after insertion, making the insertion process smoother. It can also achieve uniform glue thickness and reduce the risk of defects in appearance after molding.

[0181] At least as Figure 20 , Figure 26 as well as Figure 27 As shown, in some embodiments, the mating surface 2161 has two side mating surfaces 2161A arranged opposite each other along the second direction a2. Each of the two side mating surfaces 2161A is provided with a protruding post 218, which is respectively located on one side of the two side mating surfaces 2161A facing each other.
