DETAILED DESCRIPTION

[0061] The technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person skilled in the art without creative labor fall within the protection scope of the present application.

[0062] The embodiments of the present application provide a connector housing, a connector, an electrical device and a vehicle.

[0063] Figure 1 A structural schematic diagram of one embodiment of the connector provided in the embodiments of the present application. Figure 2 For Figure 1 Another angle view of the connector. Figure 3 For Figure 2 A sectional view of the connector in the connector along the A-A direction. As Figures 1 to 3 shown, the connector 100 includes a connector housing 110 and at least one terminal 120 connected with the connector housing 110. The connector housing 110 includes at least one mounting portion 111 for mounting the at least one terminal 120. The number of the terminals 120 can be one or more. As Figure 2 and Figure 3As shown, the connector housing 110 further includes a housing body 113, and the at least one mounting portion 111 is arranged at one side of the housing body 113 along the first direction X.

[0064] In some embodiments, as shown in Figure 2 and Figure 3 As shown, the connector housing 110 can further include at least one reinforcing portion 112 connected with the mounting portion 111 to improve the structural strength of the mounting portion 111. The reinforcing portion 112 can include a plurality of reinforcing ribs 1121 protruding from the mounting portion 111, and the plurality of reinforcing ribs 1121 are distributed at intervals.

[0065] The connector housing 110 provided by the embodiments of the present application can improve the structural strength of the reinforcing portion 112 by protruding the reinforcing portion 112 including a plurality of reinforcing ribs 1121 from the mounting portion 111, and the plurality of reinforcing ribs 1121 of the reinforcing portion 112 are distributed at intervals, thereby reducing the risk that the mounting portion 111 is deformed due to high temperature at the welding position of the terminal 120 and the pad during the welding of the terminal 120 and the pad, and the terminal 120 is offset, and the terminal 120 and the pad are not welded well.

[0066] In some embodiments, the plurality of reinforcing ribs 1121 of the reinforcing portion 112 can be protruded from one side of the mounting portion 111 along the second direction Y, and the second direction Y is at an angle with the first direction X, thereby further improving the reinforcing effect of the reinforcing portion 112 on the mounting portion 111.

[0067] The mounting portion 111 can extend along the third direction Z, and the plurality of reinforcing ribs 1121 of the reinforcing portion 112 are distributed at intervals along the third direction Z, thereby making the reinforcing portion 112 have a good reinforcing effect on each part of the mounting portion 111 along the third direction Z. The first direction X, the third direction Z and the second direction Y are at an angle with each other.

[0068] It should be noted that the first direction X, the third direction Z and the second direction Y can be perpendicular to each other, or the first direction X, the third direction Z and the second direction Y can form an acute angle with each other, which can be determined according to the structure of the connector housing 110.

[0069] In some embodiments, the mounting portion 111 may have a mounting hole 1111, which is used to allow the terminal 120 to pass through, so that the terminal 120 is installed on the mounting portion 111. When there are multiple terminals 120, the mounting portion 111 may have multiple mounting holes 1111, each of which is used to allow a terminal 120 to pass through, so that multiple terminals 120 are installed on the mounting portion 111. The multiple mounting holes 1111 of the mounting portion 111 can be arranged at intervals along the third direction Z. The terminal 120 is connected to the mounting portion 111 of the connector housing 110 by passing the terminal 120 through the mounting hole 1111 of the mounting portion 111.

[0070] It should be noted that the number of the plurality of terminals 120 can be equal to the number of the plurality of mounting holes 1111, and the plurality of terminals 120 can pass through the plurality of mounting holes 1111 in a one-to-one correspondence. Alternatively, the number of the plurality of terminals 120 can be less than the number of the plurality of mounting holes 1111, each terminal 120 can pass through a mounting hole 1111, and different mounting holes 1111 are provided with different terminals 120.

[0071] In some embodiments, as Figure 2 、 Figure 3 and Figure 5 As shown, in the third direction Z, the width of the multiple reinforcing ribs 1121 of at least one reinforcing portion 112 gradually decreases from the middle portion to the ends of the mounting portion 111. It is understandable that since the mounting portion 111 extends along the third direction Z, when the terminal 120 is welded to the pad, the high temperature at the welding point between the terminal 120 and the pad is more likely to cause deformation of the middle portion of the mounting portion 111 along the third direction Z. By gradually reducing the width of the multiple reinforcing ribs 1121 of at least one reinforcing portion 112 from the middle portion to the ends of the mounting portion 111, the structural strength of the middle portion of the reinforcing portion 112 relative to the mounting portion 111 can be further improved while the overall volume of the reinforcing portion 112 remains unchanged, which helps to reduce the risk of deformation of the middle portion of the mounting portion 111 under the influence of high temperature. At the same time, it also has a high reinforcing effect on other parts of the mounting portion 111.

[0072] Among them, the multiple reinforcing ribs 1121 of at least one reinforcing part 112 can be unevenly distributed along the third direction Z, so that the positions and sizes of the multiple reinforcing ribs 1121 of the reinforcing part 112 can be flexibly adjusted according to the deformation ease of various parts of the installation part 111, so that the deformation risk of various parts of the installation part 111 is relatively small while the overall volume of the reinforcing part 112 is reduced as much as possible.

[0073] In addition, reinforcing portions 112 may be provided on both sides of at least one mounting portion 111 along the second direction Y, thereby further improving the reinforcing effect of the mounting portion 111 .

[0074] Continue to refer toFigure 2 And Figure 3 The connector housing 110 can include two mounting portions 111 distributed along the second direction Y. The two mounting portions 111 respectively include a plurality of mounting holes 1111, and the plurality of mounting holes 1111 of each mounting portion 111 are arranged at intervals along the third direction Z.

[0075] In some embodiments, the plurality of reinforcing ribs 1121 of one reinforcing portion 112 can be connected between the two mounting portions 111, so that the reinforcing portion 112 can simultaneously strengthen the structural strength of the two mounting portions 111. Alternatively, the two mounting portions 111 can be respectively provided with reinforcing portions 112 on the sides away from each other, so that the two reinforcing portions 112 respectively strengthen the structures of the corresponding mounting portions 111.

[0076] It should be noted that the reinforcing portion 112 can be arranged between the two mounting portions 111, and the reinforcing portion 112 can be arranged on the side away from each other of the two mounting portions 111, or only the reinforcing portion 112 can be arranged between the two mounting portions 111, or only the reinforcing portion 112 can be arranged on the side away from each other of the two mounting portions 111. Of course, the former can further improve the strengthening effect of the two mounting portions 111.

[0077] As shown in Figures 1 to 3 The housing body 113 includes a partition plate 1131 arranged at an angle with the first direction X. The angle between the partition plate 1131 and the first direction X can be a right angle or an acute angle, which can be determined according to the structure of the connector housing 110. The mounting portion 111 and the reinforcing portion 112 can be arranged on the plate surface 1148 on one side of the partition plate 1131 along the first direction X, so as to further improve the connection strength between the mounting portion 111 and the reinforcing portion 112, and facilitate to improve the strengthening effect of the reinforcing portion 112 on the mounting portion 111.

[0078] As shown in Figure 3 The plate surface 1148 of the partition plate 1131 provided with the mounting portion 111 and the reinforcing portion 112 includes a first edge 1132 and a second edge 1133 distributed along the second direction Y, and a flange 1134 is arranged on the plate surface 1148 of the partition plate 1131, and the flange 1134 is located on the first edge 1132. In some embodiments, the plurality of reinforcing ribs 1121 of at least one reinforcing portion 112 can be connected between the flange 1134 and the mounting portion 111 close to the first edge 1132. By connecting the plurality of reinforcing ribs 1121 of the reinforcing portion 112 to the flange 1134, the structural stability of the plurality of reinforcing ribs 1121 can be further improved, and the strengthening effect on the mounting portion 111 close to the first edge 1132 can be improved.

[0079] In addition, the plurality of reinforcing ribs 1121 of the at least one reinforcing portion 112 can extend from the mounting portion 111 close to the second edge 1133 to the second edge 1133, so as to improve the structural strength of the plurality of reinforcing ribs 1121 of the reinforcing portion 112 connected to the mounting portion 111 close to the second edge 1133 as much as possible, and facilitate to improve the reinforcing effect on the mounting portion 111 close to the second edge 1133.

[0080] It should be noted that the plurality of reinforcing ribs 1121 of the at least one reinforcing portion 112 can be connected between the flange 1134 and the mounting portion 111 close to the first edge 1132, or the plurality of reinforcing ribs 1121 of the at least one reinforcing portion 112 can extend from the mounting portion 111 close to the second edge 1133 to the second edge 1133, or the plurality of reinforcing ribs 1121 of the at least one reinforcing portion 112 can be connected between the flange 1134 and the mounting portion 111 close to the first edge 1132, and the plurality of reinforcing ribs 1121 of the at least one reinforcing portion 112 can extend from the mounting portion 111 close to the second edge 1133 to the second edge 1133. Of course, the latter can have a better reinforcing effect on the strength of the two mounting portions 111.

[0081] Specifically, the plate surface 1148 of the partition plate 1131 is substantially perpendicular to the first direction X. The flange 1134 extends along the third direction Z in a plate shape. The flange 1134 is arranged in a plate shape, and the flange 1134 is substantially perpendicular to the second direction Y. The two mounting portions 111 protruding from the plate surface 1148 of the partition plate 1131 are integrally connected with the partition plate 1131. The reinforcing portion 112 protruding from the plate surface 1148 of the partition plate 1131 is integrally connected with the partition plate 1131. The surfaces of the reinforcing portion 112 and the mounting portion 111 away from the partition plate 1131 are flush. The reinforcing ribs 1121 of the reinforcing portion 112 extend along the second direction Y. The thickness direction of the reinforcing ribs 1121 is parallel to the third direction Z. One end of the reinforcing ribs 1121 of the reinforcing portion 112 between the flange 1134 and the mounting portion 111 close to the flange 1134 is integrally connected with the flange 1134, and the other end is integrally connected with the mounting portion 111 close to the flange 1134. The reinforcing ribs 1121 of the reinforcing portion 112 extending from the mounting portion 111 close to the second edge 1133 to the second edge 1133 are integrally connected with the mounting portion 111 close to the second edge 1133.

[0082] As Figure 1 and Figure 3As shown, the shell body 113 further comprises a plug cavity 1130 located on the side of the partition 1131 away from the mounting portion 111. The mounting portion 111 is provided with a mounting hole 1111 for the terminal 120 to pass through, and the partition 1131 is provided with a fixing hole 1135 communicating with the mounting hole 1111 and the plug cavity 1130, and the fixing hole 1135 is used for the terminal 120 to pass through so that the plug end of the terminal 120 opposite to the welding end is located in the plug cavity 1130. The plug cavity 1130 is used for the mating end plugged with the terminal 120 to be inserted, so that the terminal 120 and the mating end are stably plugged, and the electrical signal transmission between the terminal 120 and the mating end is realized.

[0083] The shell body 113 further comprises two side plates 1141 distributed on both sides of the plug cavity 1130 along the second direction Y, and a plurality of protrusions 1142 are protruded on the side of at least one side plate 1141 facing the plug cavity 1130, the plurality of protrusions 1142 are sequentially distributed along the third direction Z, and the protrusions 1142 extend along the first direction X. By protruding a plurality of protrusions 1142 on the side of at least one side plate 1141 facing the plug cavity 1130, the wall thickness of the first side plate 1141 can be more uniform, and the deformation amount of the shell body 113 during plastic molding can be reduced.

[0084] Specifically, the two side plates 1141 are respectively located on the first edge 1132 and the second edge 1133 of the partition 1131, and the side plate 1141 located on the second edge 1133 of the partition 1131 is provided with a plurality of protrusions 1142 on the side facing the plug cavity 1130. The shell body 113 is provided with a plug port communicating with the plug cavity 1130, and the plug port is located on the side of the plug cavity 1130 away from the partition 1131. The protrusions 1142 extend from the plug port to the partition 1131. Adjacent two protrusions 1142 form a groove extending along the first direction X.

[0085] The following table is the flatness data of the terminal 120 when the side plate 1141 located on the second edge 1133 of the partition 1131 is provided with a plurality of protrusions 1142 on the side facing the plug cavity 1130, and the flatness data of the terminal 120 when the side plate 1141 is not provided with the protrusions 1142. As can be seen from the table, when the side plate 1141 is provided with the protrusions 1142, the flatness of the terminal 120 is lower, and the consistency of the terminal 120 is better.

[0086]

[0087] In some embodiments, at least one mounting protrusion 1143 may be provided on a side of at least one side panel 1141 facing away from the insertion cavity 1130. A connection hole 1147 may be provided on the side of the partition panel 1131 facing away from the mounting portion 111.

[0088] In some embodiments, two mounting protrusions 1143 may be provided on a side of at least one side panel 1141 facing away from the insertion cavity 1130. The two mounting protrusions 1143 are distributed at both ends of the corresponding side panel 1141 along the third direction Z. Thus, the fixing piece 130 can be inserted into each of the mounting holes 1111 of the two mounting protrusions 1143, thereby further improving the connection stability between the connector 100 and the FPC or circuit board.

[0089] In some embodiments, mounting protrusion 1143 and rib 1142 are located on opposite sides of the same side panel 1141.

[0090] like Figure 1 and Figure 3 As shown, a guide portion 1146 is protruding from a side of at least one side plate 1141 facing the insertion cavity 1130 , wherein the guide portion 1146 extends along the first direction X. A key slot 1144 is defined on a side of the guide portion 1146 facing away from the corresponding side plate 1141 , and the key slot 1144 extends along the first direction X. The key slot 1144 of the guide portion 1146 can guide the mating end, allowing the mating end to be more accurately plugged into the terminal 120 .

[0091] The number of guide portions 1146 can be two, with the two guide portions 1146 distributed along the third direction Z at the ends of the corresponding side panels 1141, thereby further improving the guiding effect on the mating end. Furthermore, the guide portion 1146 and the rib 1142 can be provided on different side panels 1141 to prevent interference between the guide portion 1146 and the rib 1142. Specifically, the guide portion 1146 is provided on the side of the side panel 1141 facing the insertion cavity 1130, located at the first edge 1132 of the partition 1131.

[0092] In some embodiments, a cutout hole 1145 can be provided within the guide portion 1146. This cutout hole 1145 extends along the first direction X and has an opening formed at the end of the guide portion 1146 facing away from the partition 1131. Providing the cutout hole 1145 within the guide portion 1146 can make the wall thickness of the guide portion 1146 more uniform, thereby reducing the deformation of the housing body 113 during plastic molding near the guide portion 1146. This can also reduce the material used in the connector housing 110, thereby lowering the cost of the connector housing 110.

[0093] like Figures 1 to 4 As shown, the housing body 113 further includes a fixing hole 1135 in communication with the mounting hole 1111, and is used to allow the terminal 120 to pass through. At least one abutment portion 1138 may be provided on the inner circumference of the fixing hole 1135, and the abutment portion 1138 is used to abut against the edge 1212 of the terminal 120. Thus, when the terminal 120 passes through the fixing hole 1135, the abutment portion 1138 can flatten the terminal 120, keeping the terminal 120 straight, thereby enabling the terminal 120 to be more accurately plugged into the mating end.

[0094] The fixing hole 1135 and the abutting portion 1138 extend respectively along the first direction X, so that after the terminal 120 passes through the fixing hole 1135 , the portion of the terminal 120 used for plugging with the mating section remains straight along the first direction X, thereby better plugging with the mating end.

[0095] Specifically, if Figure 4 As shown, the inner circumference of the fixing hole 1135 includes two first inner side surfaces 1136 and two second inner side surfaces 1137. The two first inner side surfaces 1136 are distributed on both sides of the fixing hole 1135 along the third direction Z, and the two second inner side surfaces 1137 are distributed on both sides of the fixing hole 1135 along the second direction Y. The abutting portion 1138 includes an abutting surface 1139 for abutting against the edge 1212 of the terminal 120. The abutting surface 1139 can be a flat surface, a curved surface, or a concave curved surface. The abutting surface 1139 extends from one of the first inner side surfaces 1136 to the adjacent second inner side surface 1137, so that when the terminal 120 passes through the fixing hole 1135, the abutting portion 1138 can accurately abut against the edge 1212 of the terminal 120 and flatten the terminal 120.

[0096] In which, in the third direction Z, the ratio of the width of the abutment portion 1138 to the width of the fixing hole 1135 can be less than or equal to 1 / 4, and / or, in the second direction Y, the ratio of the height of the abutment portion 1138 to the height of the fixing hole 1135 can be less than or equal to 1 / 4, so that the abutment portion 1138 has a better leveling effect on the terminal 120 passing through the fixing hole 1135.

[0097] In some embodiments, as shown in Figure 4 The number of abutting portions 1138 is two, and the two abutting portions 1138 are distributed at both ends of the second inner side surface 1137 along the third direction Z. The two abutting portions 1138 can abut and flatten the two edges 1212 of the terminal 120, and can make the position of the terminal 120 after passing through the fixing hole 1135 more accurate.

[0098] The following table is a comparison of the flatness of the terminal 120 when the fixing hole 1135 is provided with the abutting portion 1138 and when the abutting portion 1138 is not provided. As can be seen from the table, when the fixing hole 1135 is provided with the abutting portion 1138, the flatness of the terminal 120 is lower, and the consistency of the terminal 120 is better.

[0099]

[0100]

[0101] With reference to Figure 3 , the inner circumferential surface of the mounting hole 1111 is used to be clamped with the clamping section 1213 of the terminal 120, thereby improving the positioning effect of the mounting hole 1111 on the terminal 120. Specifically, as shown in Figure 6 , the terminal 120 includes a clamping section 1213, and the outer circumferential surface of the clamping section 1213 is provided with a clamping protrusion 1214. The clamping section 1213 is used to be inserted into the mounting hole 1111, and the clamping protrusion 1214 is clamped with the inner circumferential surface of the mounting hole 1111 of the connector housing 110, thereby improving the connection stability of the terminal 120 and the connector housing 110.

[0102] The embodiments of the present application also provide a connector, which includes a connector housing. The specific structure of the connector housing can refer to the above-mentioned embodiments. Since the connector 100 adopts all the technical solutions of the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0103] The connector 100 includes a connector housing 110 and at least one terminal 120. The structure of the connector housing 110 can refer to the above-mentioned embodiments. The at least one terminal 120 is mounted on the mounting portion 111 of the connector housing 110, so that the terminal 120 is connected with the connector housing 110.

[0104] In some embodiments, as shown in Figure 6As shown, the terminal 120 can include a connecting segment 121, a transition segment 122 and a soldering segment 123 connected in sequence, the connecting segment 121 is connected with the connector housing 110, the transition segment 122 extends along the second direction Y, and the soldering segment 123 has a soldering surface 1231 on a side away from the connecting segment 121; in a direction in which the soldering segment 123 is away from the transition segment 122, the soldering segment 123 of the at least one terminal 120 protrudes from the side surface 1149 of the connector housing 110, so that the soldering surface 1231 of the terminal 120 can be in contact with the pad, and the risk that the soldering surface 1231 of the terminal 120 is not in good contact with the pad due to deformation of the connector housing 110 caused by high temperature is reduced.

[0105] It should be noted that the direction in which the soldering segment 123 is away from the transition segment 122 is parallel to the second direction Y and is unidirectional, so that the soldering segment 123 is not in contact with the transition segment 122. Figure 3 For example, the direction in which the soldering segment 123 is away from the transition segment 122 is a direction from top to bottom, and the side surface 1149 is located at the bottom of the connector housing 110.

[0106] In this way, the height difference between the soldering surface 1231 and the side surface 1149 can be greater than or equal to 0.075 mm and less than or equal to 0.15 mm, so as to further reduce the risk that the soldering surface 1231 of the terminal 120 is not in good contact with the pad due to deformation of the connector housing 110 caused by high temperature. The height difference between the soldering surface 1231 and the side surface 1149 can be 0.01 mm, 0.02 mm, 0.05 mm, 0.1 mm, etc., and can be determined according to the structure of the terminal 120 and the connector housing 110.

[0107] In addition, when the number of terminals 120 is multiple, the soldering surfaces 1231 of the multiple terminals 120 can respectively protrude from the side surface 1149 of the connector housing 110, so that the soldering surfaces 1231 of the multiple terminals 120 can be in stable contact with the pad.

[0108] In some embodiments, the soldering surface 1231 of the terminal 120 can be a rolled surface, so that the soldering surface 1231 of the terminal 120 has good surface quality, which is beneficial to reduce the risk of contact failure of the soldering surface 1231 of the terminal 120 and the pad and improve the soldering quality of the soldering surface 1231 of the terminal 120 and the pad. Specifically, the terminal 120 is formed by bending after being cut from copper material, so that the rolled surface of the plate material serves as the soldering surface 1231 of the terminal 120.

[0109] In some embodiments, as shown in FIG. 2, the soldering segment 123 of the terminal 120 can include a first soldering segment 1231 and a second soldering segment 1232 connected in sequence, the first soldering segment 1231 is connected with the transition segment 122, and the second soldering segment 1232 is connected with the first soldering segment 1231 and has a soldering surface 1231 on a side away from the first soldering segment 1231. Figure 6As shown, the connecting section 121 of the terminal 120 includes a plug-in section 1211 for passing through the fixing hole 1135, and at least one edge 1212 of the plug-in section 1211 abuts against the abutting portion 1138 in the fixing hole 1135, so that the plug-in section 1211 passing through the fixing hole 1135 is leveled by the abutting portion 1138 in the fixing hole 1135, and the position of the plug-in section 1211 passing through the fixing hole 1135 is more accurate.

[0110] In some embodiments, as shown in FIG. 1, the edge 1212 of the plug-in section 1211 of the terminal 120 abutting against the abutting portion 1138 can be provided with a rounded corner, so as to avoid the edge 1212 of the plug-in section 1211 being too sharp to scratch the abutting portion 1138 and affect the leveling effect of the plug-in section 1211 of the terminal 120 on the abutting portion 1138.

[0111] Continuing to refer to FIG. 1, Figure 6 The connecting section 121 and the welding section 123 of the terminal 120 extend along the first direction X, and the connecting section 121 and the welding section 123 are distributed on both sides of the transition section 122 along the first direction X. Thus, the copper material can be conveniently processed by being cut and then bent to form the terminal 120. Specifically, the copper material can be cut into a strip-shaped structure, a part of the strip-shaped structure is inserted into the mounting hole 1111 and the fixing hole 1135 of the connector housing 110, and then the part of the strip-shaped structure not inserted into the mounting hole 1111 and the fixing hole 1135 is bent once and twice to form the transition section 122 and the welding section 123, and the part of the strip-shaped structure inserted into the mounting hole 1111 and the fixing hole 1135 is the connecting section 121. In this way, the flatness of the terminal 120 of the connector 100 is better, and the risk of empty welding is lower.

[0112] The following table is a comparison table of the flatness of the terminal 120 inserted into the mounting hole 1111 and the fixing hole 1135 first and then bent (bending form) and the flatness of the terminal 120 bent first and then inserted into the mounting hole 1111 and the fixing hole 1135. As can be seen from the table, the flatness of the terminal 120 is better and the consistency of the terminal 120 is better when the terminal 120 is inserted into the mounting hole 1111 and the fixing hole 1135 first and then bent.

[0113]

[0114] In some embodiments, the connecting section 121 can include a clamping section 1213 connected between the transition section 122 and the plug-in section 1211, and the clamping section 1213 is provided with a clamping protrusion 1214 on the outer periphery surface, and the clamping protrusion 1214 is clamped with the inner periphery surface of the mounting hole 1111 of the connector housing 110, so that the connection between the connecting end of the terminal 120 and the mounting portion 111 is more firm.

[0115] In some embodiments, as Figures 7 to 9As shown, the connector 100 can be used for soldering with the FPC board 200. The FPC board 200 includes an upper cover film 210, a copper foil 220, a lower cover film 230 and a PCB board 240 arranged in layers. The hollowed region of the upper cover film 210 is the exposed copper foil 220 which is a solder pad for soldering with the soldering surface 1231 of the terminal 120 of the connector 100. The thickness of the upper cover film 210 can be 0.03-0.05mm. During the soldering process, a thin layer of tin paste is first applied on the copper foil 220, and then the semi-solid tin paste on the copper foil 220 is melted into liquid tin beads at high temperature. After that, the connector 100 is placed on the FPC board 200, and the tin beads cover the soldering surface 1231 through capillary phenomenon.
