Description

Technical Field

[0001] The present application relates to the technical field of connectors, and more specifically, to a connector, a motor and a powertrain. Background Art

[0002] The powertrain is an important component of a vehicle. The powertrain includes a motor and a motor controller. The motor controller is used to control the motor. Usually, the signal transmission between the motor controller and the motor is achieved through a connector. However, the existing connectors are prone to pin debonding, making it difficult to ensure the reliable connection of the connector, which in turn affects the signal transmission between the motor and the motor controller. Utility Model Content

[0003] The present application provides a connector, a motor and a power assembly, wherein the probability of pin removal in the connector is low, and reliable connection of the connector can be ensured, thereby improving the performance of the motor and the power assembly.

[0004] In a first aspect, a connector is provided, which includes a cylindrical plug housing, a group of terminals, and a group of cantilever structures. The plug housing is used to accommodate a group of terminals and to fix a group of cantilever structures, one end of a group of cantilever structures is used to fix and connect the inner cylinder wall of the plug housing, and the other end of a group of cantilever structures is arranged with intervals from the inner cylinder wall of the plug housing along a first direction. The connector also includes a cylindrical socket housing, another group of terminals, and another group of cantilever structures, the socket housing is used to accommodate another group of terminals and to fix another group of cantilever structures, one end of another group of cantilever structures is used to fix and connect the inner cylinder wall of the socket housing, and the other end of another group of cantilever structures is arranged with intervals from the inner cylinder wall of the socket housing along the first direction. The plug housing is used to be embedded in the socket housing, two groups of cantilever structures are arranged in abutment along the first direction, two groups of terminals are arranged in abutment along the first direction, one group of cantilever structures is arranged in abutment with one group of terminals along the second direction, and another group of cantilever structures is arranged in abutment with another group of terminals along the second direction.

[0005] In the connector provided by the embodiment of the present application, a group of cantilever structures abut against a group of terminals along the second direction, and one end of a group of cantilever structures is fixedly connected to the inner cylinder wall of the plug housing, so that a group of cantilever structures in the plug housing can prevent a group of terminals from moving along the second direction. Another group of cantilever structures abut against another group of terminals along the second direction, and one end of another group of cantilever structures is fixedly connected to the inner cylinder wall of the socket housing, so that another group of cantilever structures in the socket housing can prevent another group of terminals from moving along the second direction. In addition, since the two groups of cantilever structures are arranged in abutment along the first direction, the abutment force between one group of cantilever structures and a group of terminals can be increased, as well as the abutment force between another group of cantilever structures and another group of terminals can be increased. In addition, the probability of pin withdrawal of the connector is reduced, ensuring the reliable connection of the connector.

[0006] In one implementation, the distance between one group of cantilever structures and the inner cylinder wall of the plug housing gradually increases along the second direction, the minimum distance between one group of cantilever structures and the inner cylinder wall of the plug housing is equal to the distance between another group of cantilever structures and the inner cylinder wall of the plug housing, and the length of one group of cantilever structures is smaller than the length of the other group of cantilever structures.

[0007] In this way, when one group of terminals of the plug housing is inserted into place, another group of cantilever structures can fit into the gap between one group of cantilever structures and the inner tube wall of the plug housing, and one group of cantilever structures abuts against another group of cantilever structures along the first direction, thereby realizing the plug-in of the plug housing and the socket housing. When one group of terminals of the plug housing is not inserted into place, since the gap between one group of cantilever structures of the plug housing and the inner tube wall of the plug housing gradually increases along the second direction, one group of terminals of the plug housing can lift up one group of cantilever structures along the first direction. Furthermore, when the plug housing is inserted into the socket housing, the plug housing is not inserted into place, and one group of cantilever structures of the plug housing along the second direction abuts against another group of cantilever structures of the socket housing, making it impossible for the plug housing to be inserted into the socket housing. In this way, the assembler can identify that one group of terminals of the plug housing is not inserted into place.

[0008] In one implementation, the spacing between another group of cantilever structures and the inner cylinder wall of the socket housing gradually decreases along the second direction, the minimum spacing between another group of cantilever structures and the inner cylinder wall of the plug housing is equal to the spacing between one group of cantilever structures and the inner cylinder wall of the plug housing, and the length of another group of cantilever structures is less than the length of one group of cantilever structures.

[0009] When the other group of terminals of the socket housing is inserted into place, one group of cantilever structures can fit into the gap between the other group of cantilever structures and the inner tube wall of the plug housing, and one group of cantilever structures abuts against the other group of cantilever structures along the first direction, so as to realize the plugging of the plug housing and the socket housing. When the other group of terminals of the socket housing is not inserted into place, since the gap between the other group of cantilever structures of the socket housing and the inner tube wall of the socket housing is gradually reduced along the second direction, the other group of terminals of the socket housing can lift up the other group of cantilever structures along the first direction. Furthermore, when the plug housing is inserted into the socket housing, the plug housing is not inserted into place, and one group of cantilever structures of the plug housing along the second direction abuts against the other group of cantilever structures of the socket housing, so that the plug housing cannot be inserted into the socket. In this way, the assembler can identify that the other group of terminals of the plug housing is not inserted into place.

[0010] In one implementation, the maximum distance between a group of cantilever structures and the inner wall of the plug housing along the first direction is greater than the minimum distance between a group of terminals and the inner wall of the plug housing. In this way, a group of cantilever structures of the plug housing can be embedded in a group of terminals, further reducing the probability of pin withdrawal of a group of terminals in the plug housing.

[0011] The maximum distance between the other set of cantilever structures and the inner wall of the socket housing along the first direction is greater than the minimum distance between the other set of terminals and the inner wall of the socket housing. In this way, the other set of cantilever structures can be embedded in the other set of terminals, further reducing the probability of pin withdrawal of the other set of terminals in the socket housing.

[0012] In one implementation, each group of terminals includes a plurality of terminals spaced apart along a third direction, and each group of cantilever structures includes a plurality of cantilever structures spaced apart along a third direction. One side of each cantilever structure includes a protrusion, and the protrusion of each cantilever structure is used to be embedded in the terminal abutting against each cantilever structure, and one side of each cantilever structure is the side of each cantilever structure facing the terminal abutting against each cantilever structure. In this way, by processing a protrusion on one side of each cantilever structure, not only can a group of terminals of the plug housing and another group of terminals of the socket housing not produce a pin-out phenomenon, but also the manufacturing cost of the connector can be reduced.

[0013] In addition, the size of the protrusion of each cantilever structure of a group of cantilever structures along the second direction gradually increases along the first direction. In this way, on the one hand, the probability of a group of terminals of the plug housing being unpinned can be further reduced. On the other hand, during the process of each terminal being installed into the plug housing along the second direction, it can be easily engaged with a cantilever structure of the group of cantilever structures, simplifying the assembly process of a group of cantilever structures and a group of terminals.

[0014] The size of the protrusion of each cantilever structure of the other group of cantilever structures along the second direction gradually decreases along the first direction. In this way, on the one hand, the probability of the other group of terminals of the socket housing being unpinned can be further reduced. On the other hand, during the process of each terminal being installed into the socket housing in the direction opposite to the second direction, it can be easily engaged with one cantilever structure of the other group of cantilever structures, thereby simplifying the assembly process of the other group of cantilever structures and the other group of terminals.

[0015] In one implementation, the outer cylinder wall of the plug housing includes an annular groove, the annular groove is used to embed a sealing ring, the sealing ring is used to seal and connect the plug housing and the socket housing, the size of the sealing ring along the first direction is equal to or greater than the size of the cavity of the socket housing, and the size of the sealing ring along the third direction is equal to or greater than the size of the cavity of the socket housing. In this way, the sealing ring can prevent dust, foreign matter, or coolant from entering the cavity of the socket housing, thereby making the transmission between one group of terminals of the plug housing and another group of terminals of the socket housing more reliable.

[0016] In one implementation, the connector includes a clamping member, one end of which is used to be fixed to an outer cylindrical wall of the plug housing, the other end of which is spaced apart from the outer cylindrical wall along a first direction, and the clamping member is used to abut against an inner cylindrical wall of the socket housing, wherein the spacing between the clamping member and the outer cylindrical wall decreases along a second direction.

[0017] In this way, when the plug housing is inserted into the plug housing, the clamping piece can abut against the inner wall of the socket housing to achieve clamping of the plug housing and the socket housing. In addition, the installation process of the connector is simplified, the installation time of the connector is saved, and the assembly efficiency of the connector is improved.

[0018] In one implementation, one side of the clamping member includes a protrusion, and one side of the clamping member is a side of the clamping member facing away from the plug housing. The size of the protrusion gradually decreases along the second direction. In this way, the pressing force of the clamping member can be reduced, and the assembly efficiency of the plug housing and the socket housing can be improved.

[0019] In one implementation, the socket housing includes two side panels arranged opposite to each other along a first direction, one side of one side panel includes a groove, and one side of one side panel is a side of one side panel facing the other side panel. The groove is connected to an opening of the socket housing facing the plug housing, the groove is used to accommodate a part of the clamping member, and the size of the groove along the second direction is smaller than the size of one side panel.

[0020] In this way, the plug housing and the socket housing are connected by clamping the clamping piece of the plug housing in the groove, thereby simplifying the installation process of the connector, saving the installation time of the connector, and improving the assembly efficiency of the connector.

[0021] In one implementation, the other side of one side plate includes a through hole, and the other side of one side plate is the side of one side plate away from the other side plate. The through hole is used to connect the groove, and the size of the through hole along the second direction is smaller than the size of the groove, and the size of the through hole along the third direction is smaller than the size of the groove.

[0022] In this way, the protrusion of the clamping member on the plug housing can be clamped to the through hole communicated with the groove to achieve clamping with the socket housing. Thus, not only the firmness of the clamping between the plug housing and the socket housing is increased, but also the connector is lightweight.

[0023] In one implementation, the socket housing further includes another side plate, the other side plate is arranged opposite to the other side plate along the first direction, and the other side plate is used to connect the one side plate. The spacing between the one side plate and the other side plate is greater than the spacing between the other side plate and the other side plate. In this way, the structure on the socket housing that is engaged with the plug housing protrudes from the socket housing setting and does not affect the deployment of other components in the socket housing.

[0024] In one implementation, an outer cylinder wall of the socket housing includes two groups of clamping structures spaced apart along a third direction, one end of each group of clamping structures is used to fix and connect an outer cylinder wall, and the other end of each group of clamping structures is spaced apart from an outer cylinder wall. The other end of one group of clamping structures is distributed on one side of one end of one group of clamping structures facing the other group of clamping structures.

[0025] In this way, the socket housing can be assembled with other components such as a motor housing through two sets of snap-fit ​​structures on an outer cylindrical wall of the socket housing, thereby simplifying the installation process of the connector and saving the installation time of the connector.

[0026] In one implementation, an outer cylinder wall includes at least one protrusion, and each protrusion is arranged with each group of snap-fit ​​structures along the second direction. In this way, the protrusion can prevent other components from moving along the second direction, thereby improving the firmness of the connection between the socket housing and other components.

[0027] In a second aspect, a motor is provided, comprising a motor housing, a motor stator, a connecting piece and a connector as described in the first aspect and any possible implementation of the first aspect, wherein the motor stator comprises a stator winding, the motor housing is used to accommodate the motor stator, one end of the connecting piece is used to be fixedly connected to the motor housing, and the other end of the connecting piece comprises a side plate, which is used to be embedded in the gap between the socket housing and the other end of each snap-on structure.

[0028] By providing a side plate on the connecting piece, fixing one end of the connecting piece to the motor housing, and clamping the side plate of the connecting piece to the gap between the socket housing and the other end of each clamping structure, the connector can be fixed to the motor housing, simplifying the installation process of the connector and saving the installation time of the connector.

[0029] In one implementation, the side plate includes two side surfaces arranged opposite to each other along the second direction and another side surface facing away from the connector, and the other side surface includes a groove, which is connected to one of the two side surfaces. In this way, when the side plate is pushed into the gap between the socket housing and the other end of each snap-fit ​​structure, a protrusion of an outer cylinder wall of the socket housing can be embedded in the groove of the side plate, so that the socket housing and the motor housing are firmly snap-fitted.

[0030] In a third aspect, a power assembly is provided, the power assembly comprising a motor, a motor controller, and a connector as described in any one of the first aspect and possible implementations of the first aspect, wherein the motor and the motor controller are connected via the connector.

[0031] The connector described in the first aspect has a low probability of pin removal, and reliable connection of the connector can be guaranteed, so the signal transmitted between the motor and the motor controller through the connector will not be affected, thereby improving the performance of the powertrain.

[0074] The plug housing 111 includes Figure 5 The opening L shown 11 He Ru Figure 6 The bottom plate L shown 12 , opening L 11 and bottom plate L 12 Arranged along the second direction. Figure 6 As shown, the bottom plate L 12 The two groups of through holes T1-T2 are arranged at intervals along the first direction. Each group of through holes includes at least one through hole, and multiple through holes in each group of through holes are arranged at intervals along the third direction. Each through hole in each group of through holes passes through the bottom plate L along the second direction. 12 Each through hole T1 of the set of through holes T1 is used for another set of cantilever structures 122 of the socket 120 described below to pass through, and each through hole T2 of the other set of through holes T2 is used for another set of terminals 123 of the socket 120 described below to pass through.

[0075] Among them, the first direction, the second direction and the third direction are perpendicular to each other. It should be noted that the first direction can also be understood as the up-down direction or thickness direction of the connector 100, the thickness direction of the plug 110, or the thickness direction of the socket 120. The second direction can also be understood as the left-right direction or length direction of the connector 100, the length direction of the plug 110, the length direction of the socket 120, or the direction in which the plug housing 111 of the plug 110 is inserted into the socket housing 121 of the socket 120. The third direction can also be understood as the front-to-back direction or width direction of the connector 100, the width direction of the plug 110, or the width direction of the socket 120.

[0076] like Figure 7As shown, the plug 110 further includes a group of cantilever structures 112, wherein the group of cantilever structures 112 includes at least one cantilever structure 112, and the cantilever structures 112 of the group of cantilever structures 112 are arranged at intervals along the third direction. The group of cantilever structures 112 is used to be fixed to the plug housing 111. Specifically, one end A of the group of cantilever structures 112 11 The inner cylinder wall 1111 of the plug housing 111 is used to fix the other end A of a group of cantilever structures 112 along the first direction. 12 The plug housing 111 is spaced apart from the inner cylindrical wall 1111 of the plug housing 111 .

[0077] like Figure 2 As shown, the plug 110 further includes a set of terminals 113, and the set of terminals 113 includes at least one Fig. 9 The terminals 113 shown are arranged in a group of terminals 113 at intervals along a third direction. The group of terminals 113 is used to be accommodated in the plug housing 111 .

[0078] Each terminal 113 of a group of terminals 113 involved in the embodiment of the present application is generally a structure punched into a specific shape from a metal plate.

[0079] like Fig. 9 and Fig.10 As shown, each terminal 113 includes a plug terminal base 1131 and a group of cantilever springs 1132. The group of cantilever springs 1132 includes a plurality of cantilever springs, one end of each cantilever spring is fixedly connected to the plug terminal base 1131, and the other end of each cantilever spring is a free end. Fig.10 and Fig.11 As shown, a group of cantilever spring pieces 1132 includes a cantilever spring piece 1132a and another cantilever spring piece 1132b arranged at intervals along the second direction. In this way, a group of cantilever structures 112 can be embedded in the interval between a cantilever spring piece 1132a and another cantilever spring piece 1132b.

[0080] In some embodiments, Fig.10 and Fig.11 As shown, there is an angle between one cantilever spring piece 1132a and the second direction, and the angle is an acute angle. In other words, the interval between one cantilever spring piece 1132a and another cantilever spring piece 1132b gradually decreases along the second direction. In this way, on the one hand, the probability of a group of terminals 113 of the plug 110 being unpinned can be further reduced. On the other hand, when each terminal 113 is installed into the plug housing 111 along the second direction, it can be easily engaged with a cantilever structure 112 of a group of cantilever structures 112, which simplifies the assembly process of a group of cantilever structures 112 and a group of terminals 113.

[0081] Furthermore, a group of cantilever spring pieces 1132 further includes another cantilever spring piece 1132c, which is arranged on a side of a cantilever spring piece 1132a away from a group of cantilever structures 112. In this way, another cantilever spring piece 1132c can provide a relatively large force to a cantilever structure 112 through a cantilever spring piece 1132a, so as to prevent a cantilever structure 112 from breaking a cantilever spring piece 1132a.

[0082] Along the second direction, a group of cantilever structures 112 is used to abut against a group of terminals 113. Specifically, each cantilever structure 112 of a group of cantilever structures 112 is used to abut against one terminal 113 of a group of terminals 113. In this way, a group of cantilever structures 112 can limit the movement of a group of terminals 113 in the opposite direction of the second direction, that is, a group of cantilever structures 112 of the plug 110 can reduce the probability of a group of terminals 113 of the plug 110 being unpinned.

[0083] In some embodiments, along the first direction, the maximum distance between a group of cantilever structures 112 and the inner cylinder wall 1111 of the plug housing 111 is greater than the minimum distance between a group of terminals 113 and the inner cylinder wall 1111 of the plug housing 111. In this way, a group of cantilever structures 112 can be embedded in a group of terminals 113, further reducing the probability of a group of terminals 113 of the plug 110 being unpinned.

[0084] For example, Figure 7 and Fig.11 As shown, each cantilever structure 112 includes a side S facing a group of terminals 113. 11 and another side S away from a set of terminals 113 12 Among them, one side S of each cantilever structure 112 11 It can also be understood that each cantilever structure 112 abuts against the side of the terminal 113. 11 Including protrusion P 11 , the protrusion P of each cantilever structure 112 11 The terminal 113 is embedded in the terminal 113 abutting against each cantilever structure 112, such as the protrusion P of each cantilever structure 112. 11 The space between one cantilever spring piece 1131 a and another cantilever spring piece 1131 b embedded in one terminal 113 is used.

[0085] In some embodiments, such as Figure 7 and Fig.11 As shown, along the second direction, the protrusion P of each cantilever structure 112 of a group of cantilever structures 112 11The size along the first direction gradually increases. In this way, on the one hand, the probability of a group of terminals 113 of the plug 110 being unpinned can be further reduced. On the other hand, when each terminal 113 is installed into the plug housing 111 along the second direction, it can be easily engaged with a cantilever structure 112 of a group of cantilever structures 112, simplifying the assembly process of a group of cantilever structures 112 and a group of terminals 113.

[0086] In some embodiments, Figures 5 to 8 As shown, the outer wall of the plug housing 111 includes an annular groove G 11 , annular groove G 11 For embedding Figure 2 The sealing ring 117 is used to seal the plug housing 111 and the socket housing 121. The outer surface of the sealing ring 117 includes at least one annular protrusion P 14 The outer surface of the sealing ring 117 has a plurality of annular protrusions P 14 Each annular protrusion P on the outer surface of the sealing ring 117 along the first direction 14 The size of the sealing ring 117 is equal to or greater than the size of the cavity of the socket housing 121, that is, the size of the sealing ring 117 along the first direction is equal to or greater than the size of the cavity of the socket housing 121. In addition, each annular protrusion P on the outer surface of the sealing ring 117 along the third direction 14 The size of the sealing ring 117 is equal to or greater than the size of the cavity of the socket housing 121, that is, the size of the sealing ring 117 along the third direction is equal to or greater than the size of the cavity of the socket housing 121. In this way, the sealing ring 117 can prevent dust, foreign matter, or coolant from entering the cavity of the socket housing 121, thereby making the transmission between one group of terminals 113 of the plug 110 and another group of terminals 123 of the socket 120 more reliable.

[0087] In some embodiments, in order to prevent the plug 110 from being misaligned when being inserted into the socket 120, as shown in FIG. Figure 8 As shown, the outer wall of the plug housing 111 further includes at least one protrusion P 12 , multiple protrusions P 12 The outer wall of the plug housing 111 is surrounded by the plurality of protrusions P. 12 At least one protrusion P 12 The side of the socket 120 and the protrusion P 12 The included angle between the outer cylinder walls of the plug housing 111 is an obtuse angle.

[0088] In some embodiments, Figure 3As shown, the plug 110 further includes a group of cables 114, which includes a plurality of cables 114 arranged at intervals along the third direction, one end of each cable 114 is used to electrically connect to one terminal 113 of a group of terminals 113 of the plug 110, and the other end of each cable 114 is used to electrically connect to the circuit board of the motor controller. One end of each cable 114 can be embedded in the plug terminal base 1131 of one terminal 113.

[0089] In some embodiments, such as Figure 3 As shown, the plug 110 further includes a plug end cover 115, which is used to cover the opening L of the plug housing 111. 11 .like Fig.12 As shown, the plug end cover 115 includes at least one through hole 1151, and each through hole 1151 of the plug end cover 115 penetrates the plug end cover 115 along the second direction, and each through hole 1151 of the plug end cover 115 is used to pass each cable 114. In this way, the plug end cover 115 can prevent external dust, foreign matter, or coolant from entering the plug housing 111, thereby making the transmission between the circuit board of the motor controller and a group of terminals 113 of the plug 110 more reliable.

[0090] In some embodiments, such as Figure 3 As shown, the plug 110 further includes a plug sealing member 116, which is used to seal the plug housing 111. The plug sealing member 116 is arranged on one side of the plug end cover 115 facing a group of cantilever structures 112. Fig.13 As shown, the plug sealing member 116 further includes at least one through hole 1161, and each through hole 1161 of the plug sealing member 116 penetrates the plug sealing member 116 along the second direction, and each through hole 1161 of the plug sealing member 116 is used to pass each cable 114. In this way, each cable 114 passes through a through hole 1151 of the plug end cover 115, a through hole 1161 of the plug sealing member 116, and is electrically connected to one terminal 113 of a group of terminals 113 in sequence.

[0091] In some embodiments, such as Fig.13 As shown, the outer surface of the plug sealing member 116 includes at least one annular protrusion P 13 , a plurality of annular protrusions P on the outer surface of the plug sealing member 116 13 Each annular protrusion P on the outer surface of the plug sealing member 116 along the first direction 13 The size of the plug housing 111 is larger than the size of the cavity, and each annular protrusion P on the outer surface of the plug sealing member 116 along the third direction 13The size of the plug seal 116 is larger than the size of the cavity of the plug housing 111. In this way, the plug seal 116 can prevent dust, foreign matter, or coolant from entering the cavity of the plug housing 111 on the side of the plug seal 116 away from the plug end cover 115, thereby making the transmission between the circuit board of the motor controller and a group of terminals 113 of the plug 110 more reliable.

[0092] In some embodiments, such as Figures 2 to 4 As shown, the plug 110 further includes a terminal stop structure 118, one end of which is used for clamping and connecting the inner cylinder wall 1111 of the plug housing 111, and the other end of which is used for preventing a group of terminals 113 from moving along the second direction and the third direction. In the second direction, the terminal stop structure 118 of the plug 110 is arranged on one side of a group of cantilever structures 112 away from the other end of the group of cantilever structures 112, and in the first direction, the terminal stop structure 118 of the plug 110 is arranged on one side of a group of terminals 113 facing the inner cylinder wall 1111 of the plug housing 111.

[0093] Combine the following Figures 15 to 24 The structure of the socket 120 provided in the embodiment of the present application is described in detail.

[0094] like Figures 15 to 19 As shown, the socket housing 121 includes Fig.15 The opening L shown 21 He Ru Fig.17 The opening L shown 22 , opening L 21 and opening L 22 Arranged along the second direction. Figures 15 to 19 As shown, the socket housing 121 also includes a middle partition L 23 , middle partition L 23 Used to fix the inner wall of the socket housing 121. 23 Includes at least one through hole T3, the middle partition L 23 The plurality of through holes T3 are arranged at intervals along the third direction, and the middle partition L 23 The plurality of through holes T3 penetrate the middle partition L along the second direction 23 . Middle partition L 23 Each through hole T3 is used for another set of terminals 123 of the socket 120 described below to pass through. 23 The side facing the plug 110 includes at least one groove T4, and the middle partition L 23 The plurality of grooves T4 are arranged at intervals along the third direction, and the middle partition L 23 The size of the plurality of grooves T4 along the second direction is smaller than that of the middle partition L 23 Dimensions of the middle partition L 23Each groove T4 is used to accommodate another set of cantilever structures 122 of the socket 120 described below.

[0095] like Fig.19 As shown, the socket 120 further includes another set of cantilever structures 122, the other set of cantilever structures 122 includes at least one cantilever structure 122, and the multiple cantilever structures 122 of the other set of cantilever structures 122 are arranged at intervals along the third direction. The other set of cantilever structures 122 is used to be fixed to the socket housing 121. Specifically, one end A of the other set of cantilever structures 122 21 The inner cylinder wall 1211 of the socket housing 121 is used to fix the other end A of the other cantilever structure 122 along the first direction. 22 The socket housing 121 is spaced apart from the inner cylindrical wall 1211 .

[0096] like Figure 2 As shown, the plug 110 further includes another set of terminals 123, and the other set of terminals 123 includes at least one Fig. 20 The terminals 123 shown in the figure, the multiple terminals 123 of another group of terminals 123 are arranged at intervals along the third direction. The other group of terminals 123 are used to be accommodated in the socket housing 121.

[0097] Each terminal 123 of another group of terminals 123 involved in the embodiment of the present application is generally a structure punched into a specific shape from a metal plate.

[0098] like Fig. 20 As shown, each terminal 123 includes a groove 1231 on the side facing the other cantilever structure 122, and the groove 1231 is used to embed the other cantilever structure 122. The size of the groove 1231 along the second direction is equal to the protrusion P of the other cantilever structure 122. 21 The size of the groove 1231 along the first direction is equal to the protrusion P of another group of cantilever structures 122. 21 size.

[0099] Another set of cantilever structures 122 along the second direction is used to abut against another set of terminals 123. Specifically, each cantilever structure 122 of another set of cantilever structures 122 is used to abut against one terminal 123 of another set of terminals 123. In this way, another set of cantilever structures 122 can limit the movement of another set of terminals 123 along the second direction, that is, another set of cantilever structures 122 of the socket 120 can reduce the probability of pin withdrawal of another set of terminals 123 of the socket 120.

[0100] In addition, after the plug housing 111 is inserted into the socket housing 121, one group of cantilever structures 112 and another group of cantilever structures 122 are arranged in abutment with each other in the first direction, and one group of terminals 113 and another group of terminals 123 are arranged in abutment with each other in the first direction. Since one group of cantilever structures 112 and another group of cantilever structures 122 are arranged in abutment with each other in the first direction, the abutment force between one group of cantilever structures 112 and one group of terminals 113 can be increased, and the abutment force between another group of cantilever structures 122 and another group of terminals 123 can be increased. In addition, the probability of pin withdrawal of the connector 100 is reduced, and the reliable connection of the connector 100 is ensured.

[0101] In some embodiments, the maximum distance between the other group of cantilever structures 122 and the inner cylinder wall 1211 of the socket housing 121 along the first direction is greater than the minimum distance between the other group of terminals 123 and the inner cylinder wall 1211 of the socket housing 121. In this way, the other group of cantilever structures 122 can be embedded in the other group of terminals 123, further reducing the probability of pin withdrawal of the other group of terminals 123 of the socket 120.

[0102] For example, Fig.11 and Fig.19 As shown, each cantilever structure 122 includes a side surface S facing another group of terminals 123. 21 and another side S away from another set of terminals 123 22 . Among them, one side S of each cantilever structure 122 21 It can also be understood that each cantilever structure 122 abuts against the side of the terminal 123. 21 Including protrusion P 21 , the protrusion P of each cantilever structure 122 21 The terminal 123 is used to be embedded in the terminal 123 abutting against each cantilever structure 122, such as the protrusion P of each cantilever structure 122. 21 It is used to be embedded in a groove 1231 of a terminal 123 .

[0103] In some embodiments, Fig.11 and Fig.19 As shown, the protrusion P of each cantilever structure 122 of another group of cantilever structures 122 along the second direction 21 The size along the first direction is gradually reduced. In this way, on the one hand, the probability of the other group of terminals 123 of the socket 120 being unpinned can be further reduced. On the other hand, when each terminal 123 is installed into the socket housing 121 in the opposite direction of the second direction, it can be easily engaged with one cantilever structure 122 of the other group of cantilever structures 122, which simplifies the assembly process of the other group of cantilever structures 122 and the other group of terminals 123.

[0104] In some embodiments, Figure 4 and Fig.11 As shown, the distance between one group of cantilever structures 112 and the inner cylinder wall 1111 of the plug housing 111 gradually increases along the second direction, the minimum distance between one group of cantilever structures 112 and the inner cylinder wall 1111 of the plug housing 111 is equal to the distance between another group of cantilever structures 122 and the inner cylinder wall 1111 of the plug housing 111, and the length of one group of cantilever structures 112 is smaller than the length of another group of cantilever structures 122.

[0105] In this way, when one set of terminals 113 of the plug 110 is inserted into place, the other set of cantilever structures 122 can fit into the gap between one set of cantilever structures 112 and the inner wall 1111 of the plug housing 111, and one set of cantilever structures 112 abuts against the other set of cantilever structures 122 along the first direction, thereby achieving the plug-in connection between the plug 110 and the socket 120. 11 The protrusions P embedded in one set of terminals 113 and another set of cantilever structures 122 21 By embedding another set of terminals 123 , the one set of terminals 113 of the plug 110 and the other set of terminals 123 of the socket 120 cannot be de-pinned.

[0106] When a group of terminals 113 of the plug 110 is not inserted into place, due to the protrusions P of a group of cantilever structures 112 11 Due to the presence of the one group of terminals 113, the one group of cantilever structures 112 can be lifted up along the first direction. Furthermore, when the plug 110 is inserted into the socket 120, if the plug 110 is not inserted into place, the one group of cantilever structures 112 of the plug 110 and the other group of cantilever structures 122 of the socket 120 can be lifted up along the second direction, so that the plug 110 cannot be inserted into the socket 120. In this way, the assembler can identify that the one group of terminals 113 of the plug 110 is not inserted into place.

[0107] In other embodiments, the distance between another group of cantilever structures 122 and the inner cylindrical wall 1211 of the socket housing 121 gradually decreases along the second direction, the minimum distance between another group of cantilever structures 122 and the inner cylindrical wall 1111 of the plug housing 111 is equal to the distance between one group of cantilever structures 112 and the inner cylindrical wall 1111 of the plug housing 111, and the length of another group of cantilever structures 122 is less than the length of one group of cantilever structures 112.

[0108] In this way, when the other set of terminals 123 of the socket 120 are inserted into place, one set of cantilever structures 112 can fit into the interval between the other set of cantilever structures 122 and the inner cylinder wall 1111 of the plug housing 111, and one set of cantilever structures 112 abuts against the other set of cantilever structures 122 along the first direction, thereby achieving the plug-in connection between the plug 110 and the socket 120. 11 The protrusions P embedded in one set of terminals 113 and another set of cantilever structures 122 21By embedding another set of terminals 123 , the one set of terminals 113 of the plug 110 and the other set of terminals 123 of the socket 120 cannot be de-pinned.

[0109] When the other set of terminals 123 of the socket 120 is not inserted into place, the protrusions P of the other set of cantilever structures 122 21 The other set of terminals 123 can push up the other set of cantilever structures 122 along the first direction. Furthermore, when the plug 110 is inserted into the socket 120, if the plug 110 is not inserted into place, the one set of cantilever structures 112 of the plug 110 and the other set of cantilever structures 122 of the socket 120 along the second direction will push up against each other, so that the plug 110 cannot be inserted into the socket 120. In this way, the assembler can identify that the other set of terminals 123 of the plug 110 is not inserted into place.

[0110] In some embodiments, in order to prevent the plug 110 from being misaligned when being inserted into the socket 120, as shown in FIG. Fig.15 As shown, the side of the socket housing 121 facing the plug housing 111 includes at least one groove G 22 , multiple grooves G 22 The inner wall of the socket housing 121 surrounds each groove G. 22 A protrusion P is used to be embedded in the outer wall of the plug housing 111 12 Each groove G 22 The invention comprises two openings, a groove wall and a groove bottom. One opening and the groove wall are arranged opposite to each other along the second direction, and the other opening and the groove bottom are arranged opposite to each other along the third direction. In order to improve the assembly efficiency of the plug 110 and the socket 120, a plurality of grooves G are provided. 22 At least one groove G in 22 The angle between the groove wall and the groove bottom is an obtuse angle.

[0111] In some embodiments, such as Figure 3 As shown, the socket 120 further includes another set of cables 124, which includes a plurality of cables 124 arranged at intervals along the third direction, one end of each cable 124 is used to electrically connect to a terminal 123 of another set of terminals 123 of the socket 120, and the other end of each cable 124 is used to electrically connect to the stator winding of the motor. One end of each cable 124 can be embedded in one terminal 123.

[0112] In some embodiments, such as Figure 3 As shown, the socket 120 further includes a socket end cover 125, which is used to cover the opening L of the plug housing 111. 21 .like Fig.21As shown, the socket end cover 125 includes at least one through hole 1251, and each through hole 1151 of the socket end cover 125 penetrates the socket end cover 125 along the second direction, and each through hole 1151 of the socket end cover 125 is used to pass each cable 114. In this way, the socket end cover 125 can prevent external dust, foreign matter, or coolant from entering the plug housing 111, thereby making the transmission between the circuit board of the motor controller and a group of terminals 113 of the plug 110 more reliable.

[0113] In some embodiments, Figure 3 As shown, the socket 120 further includes a socket sealing member 126, which is used to seal the socket housing 121. The socket sealing member 126 is arranged on one side of the socket end cover 125 facing the other cantilever structure 122. Fig. 22 As shown, the socket sealing member 126 further includes at least one through hole 1261, and each through hole 1261 of the socket sealing member 126 penetrates the socket sealing member 126 along the second direction, and each through hole 1261 of the socket sealing member 126 is used to pass each cable 124. In this way, each cable 124 sequentially passes through a through hole 1251 of the socket end cover 125, a through hole 1261 of the socket sealing member 126, and is electrically connected to a terminal 123 of another group of terminals 123.

[0114] In some embodiments, Fig. 22 As shown, the outer surface of the socket sealing member 126 includes at least one annular protrusion P 22 , the outer surface of the socket sealing member 126 has a plurality of annular protrusions P 22 Each annular protrusion P on the outer surface of the socket sealing member 126 along the first direction 22 The size of the socket housing 121 is larger than the size of the cavity, and each annular protrusion P on the outer surface of the socket sealing member 126 along the third direction 22 The size of the socket housing 121 is larger than the size of the cavity of the socket housing 121. In this way, the socket sealing member 126 can prevent dust, foreign matter, or coolant from entering the cavity of the socket housing 121 on the side of the socket sealing member 126 away from the socket end cover 125, thereby making the transmission between the other group of terminals 123 of the socket 120 and the motor stator winding and between the other group of terminals 123 of the socket 120 and the group of terminals 113 of the plug 110 more reliable.

[0115] In addition, due to the presence of the plug sealing member 116, the socket sealing member 126 and the sealing ring 117 in the connector 100, dust, foreign matter, or coolant outside the connector cannot enter the cavity between the plug sealing member 116 and the socket sealing member 126 of the connector, thereby making the transmission between the plug 110 and the socket 120 more reliable.

[0116] In some embodiments, Fig.23 As shown, the socket 120 further includes a terminal limiting structure 128, one end of which is used for clamping and connecting another inner cylinder wall of the socket housing 121, and the other end of which is used for preventing another group of terminals 123 from moving along the second direction and the third direction. The other inner cylinder wall of the socket housing 121 is arranged opposite to the inner cylinder wall 1211 of the socket housing 121 along the first direction. In the second direction, the terminal limiting structure 128 of the socket 120 is arranged on the side of one end of another group of cantilever structures 122 away from the other end of the other group of cantilever structures 122, and in the first direction, the terminal limiting structure 128 of the socket 120 is arranged on the side of another group of terminals 123 facing the other inner cylinder wall of the plug housing 111.

[0117] Exemplarily, the plug housing 111 and the socket housing 121 are connected by a locking structure. The locking structure includes a fixed part and a movable part, the movable part is arranged on the plug housing 111, and the fixed part is arranged on the socket housing 121.

[0118] Combine the following Figures 5 to 8 The movable part of the locking structure is described in detail as the structure of the clip described below.

[0119] like Figures 5 to 8 As shown, the connector 100 includes a card connector 119, one end A of the card connector 119 31 The other end A of the clamping member 119 is fixed to an outer tube wall 1112 of the plug housing 111 along the first direction. 32 The plug housing 111 is arranged at intervals with an outer cylinder wall 1112, and the distance between the clamping member 119 and the outer cylinder wall 1112 decreases along the second direction. The clamping member 119 is used to abut against the inner cylinder wall of the socket housing 121, such as a side surface 12121 of a side plate 1212 described below, and the plug housing 111 is clamped with the socket housing 121 through the clamping member 119.

[0120] In some embodiments, such as Figures 5 to 7 As shown, the latching member 119 includes a side surface S facing away from the plug housing 111. 31 , a side surface S of the clamping member 119 31 Including protrusion P 15 In this way, the plug housing 111 passes through the protrusion P of the clamping member 119. 15 The plug housing 111 and the socket housing 121 are connected to each other to achieve a secure connection.

[0121] In some embodiments, such as Figure 7 As shown, the protrusion P along the second direction 15In this way, the pressing force of the clamping member 119 can be reduced, and the assembly efficiency of the plug housing 111 and the socket housing 121 can be improved.

[0122] In some embodiments, the projection P 15 The protrusion size is greater than or equal to 0.7 mm and less than or equal to 1.5 mm. In this way, the strength of the clamping member 119 can be enhanced and the breakage rate of the clamping member 119 can be reduced.

[0123] In some embodiments, the clamping member 119 further includes at least one through hole, the through hole and the protrusion P 15 In this way, the plug 110 can be made lighter while ensuring the strength of the card connector 119 .

[0124] Combine the following Fig.15 and Fig.16 The structure of the fixed part of the locking structure is described in detail.

[0125] like Fig.15 As shown, the socket housing 121 includes two side plates arranged opposite to each other along a first direction, one side plate 1212 of the two side plates includes a side surface 12121 facing the other side plate 1213 and another side surface 12122 away from the other side plate 1213, and one side surface 12121 of the side plate 1212 includes a groove G 21 , Groove G 21 The opening L of the socket housing 121 toward the plug housing 111 21 Connected, groove G 21 The groove G along the second direction is used to accommodate part of the clamping member 119. 21 The size of the side plate 1212 is smaller than that of the side plate 1212. In this way, the clamping member 119 of the plug housing 111 is clamped into the groove G. 21 In the process, the plug housing 111 and the socket housing 121 are snap-fitted together.

[0126] In some embodiments, Fig.15 and Fig.16 As shown, the other side surface 12122 of the side plate 1212 includes a through hole T5, and the through hole T5 is used to connect the groove G 21 , the size of the through hole T5 along the second direction is smaller than the groove G 21 The size of the through hole T5 along the third direction is smaller than that of the groove G. 21 Thus, the protrusion P of the clamping member 119 on the plug housing 111 is 15 Can be snapped into groove G 21 The connected through hole T5 can realize the snap connection with the socket housing 121 , thereby increasing the firmness of the snap connection between the plug housing 111 and the socket housing 121 .

[0127] In some embodiments, such as Fig.15 As shown, the socket housing 121 further includes another side plate 1214, which is arranged opposite to the other side plate 1213 of the two side plates along the first direction, and the other side plate 1213 is used to connect one side plate 1212 of the two side plates.
