[0146] Example embodiments will now be described more fully with reference to the accompanying drawings. However, the example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments described herein; rather, these embodiments are provided so that this application will be comprehensive and complete and will fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their repeated description will be omitted. "Or" and "or" in the specification may both mean "and" or "or". Although the terms "above", "below", "between", etc. may be used in this specification to describe different exemplary features and elements of the present application, these terms are used herein only for convenience, for example, according to the directions of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of this application. Although "first", "second", or "third" are used in this specification to represent certain features, they are only used to represent the function and are not intended to limit the number and importance of specific features.

[0147] In order to solve the above technical problems, the embodiments of the present application provide an electrical connector and an electrical connector combination including the electrical connector. The electrical connector includes: a front mating portion, which can be received in the cutout of the mounting panel and includes a mating surface; a flange, which extends outward from the front mating portion and has a size larger than the size of the cutout of the mounting panel; a mounting component, which is arranged opposite to the flange, and the two together capture the mounting panel; and a rear portion, which is provided with a terminal receiving cavity extending inward to the mating surface from its rear surface; wherein the flange forms an angle with the longitudinal axis of the terminal receiving cavity, and the flange is parallel to the mating surface. The electrical connector combination includes a first electrical connector and a second electrical connector, and the first electrical connector adopts the structure of the aforementioned electrical connector. After the first electrical connector is connected to the second electrical connector, since the flange of the first electrical connector is parallel to the mating surface and the mating surface of the first electrical connector is parallel to the mounting panel, water vapor or condensation flows out along the direction of gravity and is not easily accumulated on the mating surface of the second electrical connector, thereby improving the moisture-proof effect.

[0148] Figures 1 to 19 The structure of the electrical connector assembly of the first embodiment of the present application is shown. Figure 1 and Figure 2As shown, the electrical connector assembly includes a first electrical connector 1 and a second electrical connector 4. The first electrical connector 1 can be received in a cutout 91 of a mounting panel 9. Figure 1 As shown, the front end of the first electrical connector 1 is mated with the front end of the second electrical connector 4. Figure 6 As shown, for the first electrical connector 1, the side of the first mating surface 1111 is the front side, and the side where the first conductor 16 extends is the rear side. The first conductor 16 can be a cable or other conductive material crimped with the first terminal. Figure 16 As shown, for the second electrical connector 4, the side of the second mating surface 4111 is the front side, and the side where the second conductor 43 extends is the rear side. The second conductor 43 can be a cable or other conductive material crimped with the second terminal.

[0149] like Figures 2 to 11 As shown, in the first embodiment, the first electrical connector 1 includes a first shell 11, a plurality of first terminals 15 and a plurality of first conductors 16 connected to the first terminals 15. The first shell 11 includes a front mating portion 111, a flange 112, a mounting component 113 and a rear portion 114. The front mating portion 111 can be received in the cutout 91 of the mounting panel 9, and the front mating portion 111 includes a first mating surface 1111. The flange 112 extends outward from the front mating portion 111, and the size of the flange 112 is larger than the size of the cutout 91 of the mounting panel 9. A sealing component, such as a sealing ring or a sealant, can be provided between the flange 112 and the mounting panel 9 to seal the contact surface between the flange 112 and the mounting panel 9. As shown Figure 3 As shown, optionally, a sealing member mounting portion 1121 may be provided at the flange 112, and the sealing member is arranged at the position of the sealing member mounting portion 1121. The mounting component 113 is arranged opposite to the flange 112, and the mounting component 113 and the flange 112 jointly capture the mounting panel 9. A terminal receiving cavity 115 extending inwardly to the first mating surface 1111 is provided from the rear surface of the rear portion 114, and the terminal receiving cavity 115 is used to accommodate a plurality of first terminals 15. The rear surface of the rear portion 114 is sealed by a sealing member 13, and a first rear cover 14 is provided to prevent the sealing member 13 from falling off, and to further squeeze the sealing member 13 to improve the sealing and waterproof effect of the rear surface of the rear portion 114. In this embodiment, there are two sealing members 13, and in other embodiments, these two sealing members 13 can be integrated into one sealing member.

[0150] like Figure 6 As shown, the S1 direction is the extension direction of the flange 112. The S2 direction is the longitudinal axis of the terminal receiving cavity 115. The S3 direction is the extension direction of the first mating surface 1111. In this embodiment, the longitudinal axis of the terminal receiving cavity 115 extends in a straight line. The flange 112 forms an angle a with the longitudinal axis of the terminal receiving cavity 115. Figure 1 and Figure 6As can be seen, flange 112 is parallel to first mating surface 1111. After first electrical connector 1 is installed on mounting panel 9 and mated with second electrical connector, both first mating surface 1111 of first electrical connector 1 and second mating surface of second electrical connector are parallel to mounting panel 9. Water vapor or condensation will flow out in the direction of gravity and will not easily accumulate on the second mating surface of second electrical connector, thus improving the waterproof and moisture-proof performance of the electrical connector assembly. Furthermore, flange 112 forms an angle a with the longitudinal axis of terminal receiving cavity 115. To facilitate mating, the terminal mating portions 412 located on the second mating surface 4111 side of second electrical connector 4 have different lengths in their upper and lower rows. This serves as a foolproofing measure when second electrical connector 4 is mated to first electrical connector 1.

[0151] like Figures 2 to 11 As shown, the mounting component 113 includes at least one locking elastic arm 1131 and at least one blocking member 1132. In this embodiment, the mounting component 113 includes a pair of locking elastic arms 1131 and a pair of blocking members 1132. The locking elastic arm 1131 includes a fixed end and a movable end, and the movable end is the distal end of the locking elastic arm 1131. The blocking member 1132 is arranged opposite to the movable end of the corresponding locking elastic arm 1131. The locking elastic arm 1131 and the flange 112 jointly capture the mounting panel 9, and the distance between the movable end of the locking elastic arm 1131 and the flange 112 varies with the thickness of the mounting panel 9. During installation, first insert the first electrical connector 1 into the cutout 91 of the mounting panel 9. At this time, the protrusion 92 of the mounting panel 9 and the blocking member 1132 are separated and do not form an abutment. Then, rotate the first electrical connector 1 relative to the mounting panel 9 until the blocking member 1132 abuts against the protrusion 92 of the mounting panel 9. The protrusion 92 prevents the first electrical connector 1 from continuing to rotate, completing the installation process of the first electrical connector 1 on the mounting panel 9. This embodiment ensures the installation reliability of the first electrical connector 1 and the mounting panel 9 by cooperating the locking elastic arm 1131, the blocking member 1132, the flange 112 and the mounting panel 9. In addition, the distance between the locking elastic arm 1131 and the flange 112 is adjustable, so that the first electrical connector 1 is compatible with mounting panels 9 of various thicknesses. Figure 8 As shown, the installation component 113 also includes at least one arc-shaped guide member 1133, which is located on the inner side of the locking elastic arm 1131 and the blocking member 1132, providing a guiding function for the rotation process of the first electrical connector 1 relative to the installation panel 9, so that the installation process of the first electrical connector 1 is smoother.

[0152] Combine Figure 3 、 Figures 8 to 15It can be seen that the first electrical connector 1 also includes a terminal stopper 12, the first terminal 15 is at least partially installed inside the terminal receiving cavity 115, and the terminal stopper 12 is located on the front side of the first terminal 15. The terminal stopper 12 cooperates with the structure inside the first shell 11 to block the displacement of the first terminal 15, preventing the first terminal 15 from being excessively inserted forward when inserted into the terminal receiving cavity 115, and also preventing the first terminal 15 from being withdrawn to the rear side after being inserted into the terminal receiving cavity 115. In this embodiment, the terminal stopper 12 includes an end 121, a plurality of protrusions 123 extending rearward from the end 121, and two extension sections 122 extending rearward from both sides of the end 121, and the two extension sections 122 have a certain degree of elasticity. The first shell 11 also includes mounting cavities 117 located on both sides of the terminal receiving cavity 115, and the two extension sections 122 of the terminal stopper 12 are inserted from the front side into the interior of the mounting cavity 117. As shown Figure 9 As shown, a protrusion 1171 is provided on one side wall of the installation cavity 117, and the upper and lower sides of the protrusion 1171 are formed into inclined guide surfaces. The upper and lower side walls of the installation cavity 117 are also provided with a raised first stop portion 116. The outer side of the extension section 122 of the terminal stopper 12 is provided with a second stop portion 1221 that cooperates with the first stop portion 116, and the rear end of the extension section 122 is provided with a third stop portion 1222 that cooperates with the protrusion 1171. Figure 10 and Figure 11 As shown, a stop arm 1151 is provided in the terminal receiving cavity 115 of the first housing 11. The stop arm 1151 has a certain degree of elasticity. The first terminal 15 is provided with a terminal groove 151. The stop arm 1151 cooperates with the terminal groove 151 to prevent displacement of the first terminal 15. The front end of the first housing 11 is also provided with a mating groove 118 for accommodating the boss 123.

[0153] The following combination Figures 8 to 15 The process of installing the first terminal 15 and the terminal stopper 12 into the first housing 11 is described below. Figures 8-11 As shown, first, the terminal stopper 12 is inserted from the front side of the first housing 11 to the front end of the first housing 11. During the insertion, the guide surface of the protrusion 1171 can guide the insertion of the extension section 122. The third stopper 1222 moves to the rear side of the protrusion 1171, and the second stopper 1221 is blocked by the first stopper 116, thereby keeping the terminal stopper 12 in place. Figure 9 The status shown. Figure 11As shown, the terminal stopper 12 is not yet fully installed and is in the pre-assembly position. The boss 123 has not yet been installed in the mating groove 118, and the boss 123 does not block the inward movement of the stop arm 1151. At this time, the seal 13 is installed, and the first terminal 15 is inserted from the rear end of the first housing 11. The stop arm 1151 is moved inward by the force of the first terminal 15 to make way for the first terminal 15, so that the first terminal 15 is fully installed and the terminal groove 151 of the first terminal 15 is engaged with the stop arm 1151.

[0154] like Figures 12-15 As shown, when the first terminal 15 is installed in place and the terminal stopper 12 is in the pre-assembly position, the terminal stopper 12 is further pressed toward the rear side so that the second stopper 1221 passes over the first stopper 116 and moves to the rear side of the first stopper 116, as shown in FIG. Figure 13 As shown, the terminal stopper 12 is now installed in place and reaches the assembly completion position, as shown in FIG. Figure 15 As shown, at this time, the boss 123 enters the mating groove 118, and the boss 123 is located on the inner side of the stop arm 1151, blocking the movement of the stop arm 1151 toward the inside, thereby maintaining a stable engagement between the stop arm 1151 and the terminal groove 151, and the first terminal 15 is maintained in the current position by the stop arm 1151, thereby improving the position stability of the first terminal 15.

[0155] When the terminal stopper 12 is installed, a first buffer zone is formed between the end 121 and the first mating surface 1111 of the first housing 11. When moisture or condensation infiltrates through the front mating portion 111, this first buffer zone and the angled relationship between the flange 112 and the longitudinal axis of the front mating portion 111 prevent the moisture or condensation from infiltrating into the first terminal 15. The terminal stopper 12 of this embodiment can also be used with other types of housings and is not limited to the structure of the first housing 11 defined in this embodiment. For example, in an alternative embodiment, the terminal stopper 12 is inserted from the front side of a housing without a flange, and a stopper arm, a protrusion, and a mating groove are provided within the housing to mate with the terminal stopper 12. This can also achieve the terminal position stability and waterproof sealing effects of the terminal stopper 12. Alternatively, in another alternative embodiment, the housing flange can be non-parallel to the front mating surface at a certain angle, and the stopper arm, protrusion, and mating groove provided within the housing can also mate with the terminal stopper 12, forming another technical solution.

[0156] like Figure 13 and Figure 16 As shown, a first locking portion 1112 is provided on a side wall of the front mating portion 111 of the first electrical connector 1 for interlocking with the latch mechanism 413 of the second electrical connector 4 . Figures 16-19The structure of the second electrical connector 4 in the first embodiment is shown. The second electrical connector 4 includes a second housing 41, a plurality of second terminals 42, a plurality of second conductors 43, and a second rear cover 44. The second conductors 43 are connected to the rear of the second terminals 42. The second housing 41 includes a body 411 and a terminal mating portion 412 provided on the front side of the body 411. The front side of the body 411 is a second mating surface 4111. Figure 1 、 Figure 3 and Figure 16 It can be seen that when the second electrical connector 4 is connected to the first electrical connector 1, the second mating surface 4111 mates with the first mating surface 1111 of the first electrical connector 1. A latch mechanism 413 is provided above the body 411. The latch mechanism 413 includes at least one cantilever 4133, at least one support portion 4135 connected to the side of the cantilever 4133, and a pressing portion 4131 extending upward and rearward from the cantilever 4133. A second locking portion 4134 is provided on the front side of the cantilever 4133. The pressing portion 4131 is suspended relative to the upper surface of the body 411, and a space is formed between the pressing portion 4131 and the body 411 to accommodate the downward movement of the pressing portion 4131 under force. When the first electrical connector 1 and the second electrical connector 4 are mated, the first locking portion 1112 and the second locking portion 4134 lock with each other, maintaining the mating stability of the first electrical connector 1 and the second electrical connector 4.

[0157] like Figures 16-19 As shown, the latch mechanism 413 includes two cantilever arms 4133 and two connecting arms 4132. The second electrical connector 4 also includes a blocking frame 415 disposed above the body 411. The blocking frame 415 includes a front baffle 4151 and two side baffles 4152 connected to either side of the front baffle 4151. The front baffle 4151 is disposed in front of the latch mechanism 413, and the two side baffles 4152 are disposed on either side of the latch mechanism 413 and outside the two cantilever arms 4133. The blocking frame 415 can prevent external cables from becoming entangled in the latch mechanism 413 and affecting its operation. It can also prevent the latch mechanism 413 from being damaged by excessive force when attempting to remove an entangled cable. The first end of the connecting arm 4132 is connected to the side of the cantilever 4133 to form a rotation fulcrum 4136 , and the second end is connected to the side baffle 4152 to form a support portion 4135 . The support portion 4135 provides support and fixation for the cantilever 4133 .

[0158] When plugging the first electrical connector and the second electrical connector 4, the second locking portion 4134 of the cantilever 4133 first hits the first locking portion, causing the cantilever 4133 to tilt up. After the second locking portion 4134 leaves the first locking portion due to continued movement in the plugging direction, the front end of the cantilever 4133 falls down, and the second locking portion 4134 and the first locking portion are locked with each other, preventing the second electrical connector 4 from accidentally separating from the first electrical connector, thereby improving the connection stability between the two. When the first electrical connector and the second electrical connector 4 need to be separated, the pressing portion 4131 of the second electrical connector 4 is pressed to move it downward, and the second locking portion 4134 on the front side tilts up and can be separated from the first locking portion. Figure 19 As shown, because the pivot point 4136 and support portion 4135 of cantilever 4133 are located at different positions, the forces applied to cantilever 4133 during pressing and locking are dispersed, thereby improving the service life of latch mechanism 413. The second end of connecting arm 4132 extends rearward relative to the first end, such that the extension direction of connecting arm 4132 is substantially parallel to the extension direction of cantilever 4133. The first end of connecting arm 4132 can be connected to cantilever 4133 as needed. Optionally, the first end of connecting arm 4132 is connected to the center of cantilever 4133 in the longitudinal direction. Therefore, by providing connecting arm 4132 between cantilever 4133 and blocking frame 415, the moment arm of cantilever 4133 can be extended, resulting in a longer elastic distance for cantilever 4133 during forced movement, better elasticity, and less likely to break during deformation.

[0159] Figures 20-34 The structure of the electrical connector assembly of the second embodiment of the present application is shown. In the second embodiment, the first electrical connector 2 includes a first shell 21, a plurality of first terminals 25 and a plurality of first conductors 26 connected to the first terminals 25. The first shell 21 includes a front mating portion 211, a flange 212, a mounting component 213 and a rear portion 214. The front mating portion 211 can be received in the cutout of the mounting panel 9, and the front mating portion 211 includes a first mating surface 2111. The flange 212 extends outward from the front mating portion 211, and the size of the flange 212 is larger than the size of the cutout of the mounting panel 9. A sealing component, such as a sealing ring or a sealant, can be provided between the flange 212 and the mounting panel 9 to seal the contact surface between the flange 212 and the mounting panel 9. The mounting component 213 is arranged opposite to the flange 212, and the mounting component 213 and the flange 212 jointly capture the mounting panel 9. A terminal receiving cavity 215 extending inwardly to the first mating surface is provided from the rear surface of the rear portion 214. The terminal receiving cavity 215 is used to accommodate a plurality of first terminals 25. The rear surface of the rear portion 214 is sealed by a sealing member 23. In this embodiment, the longitudinal axis of the terminal receiving cavity 215 extends in a straight line. The flange 212 forms an angle with the longitudinal axis of the terminal receiving cavity 215. The flange 212 is parallel to the first mating surface 2111, as shown in FIG. Figure 22 As shown, a first buffer zone 219 is formed between the side of the terminal receiving cavity 215 near the first mating surface 2111 and the first mating surface 2111 of the first housing 21. After the first electrical connector 2 is installed on the mounting panel 9 and mated with the second electrical connector, the first mating surface 2111 of the first electrical connector 2 and the second mating surface of the second electrical connector are both parallel to the mounting panel 9. Water vapor or condensation will flow out in the direction of gravity and will not easily accumulate on the second mating surface of the second electrical connector, thereby improving the waterproof and moisture-proof performance of the electrical connector assembly. At the same time, the flange 212 forms an angle with the longitudinal axis of the terminal receiving cavity 215. To achieve mating, the terminal mating portions located on the second mating surface side of the second electrical connector have different lengths in the upper and lower rows, which serves as a foolproofing measure when the second electrical connector is mated to the first electrical connector.

[0160] like Figure 21 and Figure 22 As shown, in this embodiment, the mounting component 213 includes at least one mounting arm 2131, with a plurality of ridges 2132 provided at the distal end of the mounting arm 2131. The mounting arm 2131 and the flange 212 jointly capture the mounting panel 9, with the inner wall of the cutout of the mounting panel 9 being retained by a ridge 2132 of the mounting arm 2131. The plurality of ridges 2132 can adapt to mounting panels 9 of varying thicknesses. When the first electrical connector 2 is mounted on the mounting panel 9, mounting panels 9 of varying thicknesses will engage with different ridges 2132, making the first electrical connector 2 compatible with mounting panels 9 of varying thicknesses.

[0161] like Figure 23 As shown, the first housing 21 further includes mounting cavities 218 located on both sides of the terminal receiving cavity 215. Figures 25-32As shown, the first electrical connector 2 also includes a terminal position assurance mechanism 22. The first terminal 25 and the terminal position assurance mechanism 22 are at least partially mounted within the terminal receiving cavity 215. The terminal position assurance mechanism 22 can prevent the first terminal 25 from moving in the front-to-back direction. Specifically, the first terminal 25 includes a terminal slot 251 and a first mating portion 252. The terminal position assurance mechanism 22 includes two elastic arms 223 and a plurality of second mating portions 221 located between the two elastic arms 223. Each second mating portion 221 mates with the first mating portion 252 of a first terminal 25. Each elastic arm 223 also has a third mating portion 222. The inner wall of the mounting cavity 218 of the first housing 21 is provided with at least one first protrusion 216 that mates with the third mating portion 222, and at least one second protrusion 217 corresponding to the first protrusion 216. The second protrusion 217 is located in front of the corresponding first protrusion 216. The first housing 21 is also provided with at least one stop arm 2151 and at least one stop portion 2152. When installing the sealing member 23, the first terminal 25 and the terminal position ensuring mechanism 22, first insert the terminal position ensuring mechanism 22 into the first housing 21 from the rear to the front. Figure 26 and Figure 28 The pre-assembly position is shown, where the third mating portion 222 is mated with the first protrusion 216 in the first housing 21. The first protrusion 216 helps the assembler understand the pre-assembly position when inserting the terminal position assurance mechanism 22. The seal 23 and the first terminal 25 are then inserted into the terminal receiving cavity 215 from the rear to the front. Figure 28 The figure shows a state where the first terminal 25 is not installed in place. The terminal groove 251 of the upper first terminal 25 is located behind the stop arm 2151, the first mating portion 252 is located behind the stop portion 2152, and the second mating portion 221 is located behind the first mating portion 252 and is spaced apart from the first mating portion 252 without applying any force. Then, the terminal position assurance mechanism 22 is further pushed forward. The second mating portion 221 of the terminal position assurance mechanism 22 moves forward and contacts the first mating portion 252. By mating with the first mating portion 252, the first terminal 25 is pushed into place. Figure 30 and Figure 32 In the assembled position shown, the third mating portion 222 is mated with the second protrusion 217 in the first housing 21, the terminal groove 251 is engaged with the stop arm 2151, and the first mating portion 252 is stopped by the rear side of the stop portion 2152. The design of the terminal position assurance mechanism 22 in this embodiment solves the problem in the prior art that the terminal position assurance mechanism 22 cannot be used due to the addition of the sealing member 23. Figure 30 and Figure 32In the state, the terminal position assurance mechanism 22 and the first terminal 25 are both installed in place, and under the cooperation and stopping action of the third mating portion 222 and the second protrusion 217, the position stability of the terminal position assurance mechanism 22 is maintained. Under the cooperation and stopping action of the second mating portion 221 and the first mating portion 252, the cooperation and stopping action of the first mating portion 252 and the stopping portion 2152, and the interlocking action of the terminal groove 251 and the stop arm 2151, the position stability of the first terminal 25 is ensured, and the sealing effect is achieved at the same time.

[0162] In the second embodiment, the first electrical connector 2 includes a first locking portion 2112 that mates with the second electrical connector. The second electrical connector can employ the same structure as the second electrical connector in the first embodiment, but the present application is not limited thereto. In other alternative embodiments, the second electrical connector can employ other electrical connector structures that can mate with the first electrical connector 2 to achieve the function of an electrical connector combination, and all such structures fall within the scope of protection of the present application.

[0163] The terminal position assurance mechanism 22 of this embodiment can also be used in conjunction with other forms of housings, and is not limited to the structure of the first housing 21 defined in this embodiment. For example, in an alternative embodiment, the terminal position assurance mechanism 22 is inserted from the rear side of a housing without a flange, and a first protrusion and a second protrusion that cooperate with the terminal position assurance mechanism 22 are provided inside the housing. This can also achieve the terminal position stability and waterproof sealing effect of the terminal position assurance mechanism 22. Alternatively, in another alternative embodiment, the flange of the housing can also be non-parallel to the front mating surface and form a certain angle, and the first protrusion and the second protrusion are provided inside the housing, which can also cooperate with the terminal position assurance mechanism 22 to form another technical solution.

[0164] Figures 35-43The structure of an electrical connector assembly according to a third embodiment of the present application is shown. In the third embodiment, the first electrical connector 3 includes a first housing 31, a plurality of first terminals 35, and a plurality of first conductors 36 connected to the first terminals 35. The first housing 31 includes a front mating portion 311, a flange 312, a mounting member 313, and a rear portion 314. The front mating portion 311 is receivable in a cutout of a mounting panel and includes a first mating surface 3111. The flange 312 extends outward from the front mating portion 311 and is larger than the cutout of the mounting panel. A sealing member may be provided between the flange 312 and the mounting panel to seal the contact surface between the flange 312 and the mounting panel. The mounting member 313 is disposed opposite the flange 312, and the mounting member 313 and the flange 312 jointly capture the mounting panel. A terminal receiving cavity 315 is defined from the rear surface of the rear portion 314, extending inwardly to the first mating surface 3111. The terminal receiving cavity 315 is configured to accommodate the plurality of first terminals 35. The rear surface of the rear portion 314 is sealed by the seal 33. In this embodiment, the longitudinal axis of the terminal receiving cavity 315 extends in a straight line. The flange 312 forms an angle with the longitudinal axis of the terminal receiving cavity 315. The flange 312 is parallel to the first mating surface 3111, as shown in FIG. Figure 38 As shown, a first buffer zone 319 is formed between the side of the terminal receiving cavity 315 near the first mating surface 3111 and the first mating surface 3111 of the first housing 31. After the first electrical connector 3 is installed on the mounting panel and mated with the second electrical connector, the first mating surface 3111 of the first electrical connector 3 and the second mating surface of the second electrical connector are both parallel to the mounting panel. Water vapor or condensation will flow out in the direction of gravity and will not easily accumulate on the second mating surface of the second electrical connector, thereby improving the waterproof and moisture-proof performance of the electrical connector assembly. At the same time, the flange 312 forms an angle with the longitudinal axis of the terminal receiving cavity 315. To achieve mating, the terminal mating portions located on the second mating surface side of the second electrical connector have different lengths in the upper and lower rows, which serves as a foolproofing measure when the second electrical connector is mated to the first electrical connector.

[0165] like Figures 35-38As shown, the mounting component 313 includes at least one mounting arm 3131. The mounting arm 3131 includes a fixed end 3131b fixed to the front mating portion 311 and a movable end 3131a disposed opposite the flange 312. The movable end is the distal end of the mounting arm 3131. The movable end of the mounting arm 3131 is provided with multiple ridges 3132. The mounting arm 3131 and the flange 312 jointly capture the mounting panel, with the inner wall of the cutout of the mounting panel being retained by a ridge 3132 of the mounting arm 3131. The multiple ridges 3132 can adapt to mounting panels of different thicknesses. When the first electrical connector 3 is mounted on the mounting panel, mounting panels of different thicknesses will engage different ridges 3132, allowing the first electrical connector 3 to adapt to mounting panels of different thicknesses. Mounting arms 3131 are provided above and below the front mating portion 311.

[0166] like Figures 35-43 As shown, the first electrical connector 3 further includes a terminal position assurance mechanism 32. The first terminal 35 and the terminal position assurance mechanism 32 are at least partially mounted within the terminal receiving cavity 315. The terminal position assurance mechanism 32 engages with the first terminal 35 to prevent the first terminal 35 from moving in the front-to-back direction. Specifically, a mounting groove 3113 extending inward is defined in the sidewall of the first housing 31. The mounting groove 3113 communicates with the terminal receiving cavity 315, and the terminal position assurance mechanism 32 is mounted within the mounting groove 3113.

[0167] like Figures 36-43 As shown, the terminal position assurance mechanism 32 is a cross-shaped structure comprising a longitudinal beam and a transverse beam arranged crosswise. The first terminal 35 is provided with a first mating portion 351, and the longitudinal beam of the cross-shaped structure is provided with a second mating portion 321 that engages with the first mating portion 351. In this embodiment, the first mating portion 351 is a groove, and the position of the longitudinal beam of the cross-shaped structure corresponding to the first mating portion 351 forms the second mating portion 321, which is embedded in the groove of the first terminal 35.

[0168] like Figures 42-43 As shown, the mounting groove 3113 is connected to the first side wall 31a and the second side wall 31b of the first housing 31, and the second end of the terminal position ensuring mechanism 32 is provided with a pair of elastic support arms 323, which are supported on the inner wall of the mounting groove 3113 near the second side wall 31b to keep the second end of the terminal position ensuring mechanism 32 inside the mounting groove 3113. Here, the first side wall 31a and the second side wall 31b of the first housing 31 refer to Figure 36The left and right walls of the front mating portion 311 of the first shell 31 from the perspective of . A protrusion 3231 is provided on the outer side of the elastic support arm 323, and the protrusion 3231 abuts against the inner wall of the mounting groove 3113. The first side wall 31a of the first shell 31 is provided with at least one first stop portion 316, and the first end of the terminal position ensuring mechanism 32 is provided with at least one second stop portion 322, and the first stop portion 316 abuts against the second stop portion 322 to prevent the terminal position ensuring mechanism 32 from falling outward from the first side wall 31a of the first shell 31. Therefore, the first and second ends of the terminal position ensuring mechanism 32 form a stable fit with the first shell 31, maintaining the stability of the terminal position ensuring mechanism 32 installed in the first shell 31. The terminal position ensuring mechanism 32 in this embodiment can be directly inserted into the first shell 31 at one time, and the installation operation is simpler. The second end of the terminal position ensuring mechanism 32 is also provided with an operating portion 324. When the terminal position ensuring mechanism 32 needs to be removed from the installation groove 3113 , a tool can be used to clamp the operating portion 324 and pull the terminal position ensuring mechanism 32 outward.

[0169] In the third embodiment, the first electrical connector 3 includes a first locking portion 3112 that mates with the second electrical connector. The second electrical connector can employ the same structure as the second electrical connector in the first embodiment, but the present application is not limited thereto. In other alternative embodiments, the second electrical connector can also employ other electrical connector structures that can mate with the first electrical connector to achieve the function of an electrical connector combination, and all such structures fall within the scope of protection of the present application.

[0170] The terminal position assurance mechanism 32 of this embodiment can also be used in conjunction with other forms of housings, and is not limited to the structure of the first housing 31 defined in this embodiment. For example, in an alternative embodiment, the terminal position assurance mechanism 32 is inserted from the front side of a housing without a flange, and a mounting groove is provided on the housing to cooperate with the terminal position assurance mechanism 22, which can also achieve the terminal position stability and sealing and waterproofing effects of the terminal position assurance mechanism 22. Alternatively, in another alternative embodiment, the flange of the housing can also be non-parallel to the front mating surface and form a certain angle, and a mounting groove is provided inside the housing, which can also cooperate with the terminal position assurance mechanism 22 to form another technical solution.

[0171] like Figure 37 and Figure 38As shown, in the third embodiment, the upper and lower mounting arms 3131 are connected at the distal ends of the movable ends 313a by a connecting arm 3133 to enhance the stability and rigidity of the mounting arms 3131. The mounting arms 3131 are fixed to the fixed arms 3134 at the fixed ends 3131b. It should be noted that the location where the mounting arms 3131 are connected is not limited, as long as the stability and rigidity of the mounting arms 3131 are enhanced. For example, the connecting arm 3133 may be positioned between the fixed ends 3131b and the movable ends 3131a, or near the fixed ends 3131b.

[0172] Figures 44-48 FIG. 4 shows the structure of the first electrical connector according to the fourth embodiment of the present application. Figures 44-46 As shown, in the fourth embodiment, the first shell 51 of the first electrical connector 5 includes a front mating portion 511 and a flange 512. The front side of the front mating portion 511 includes a first mating surface 5111. A plurality of mounting components 513 are provided on the side of the front mating portion 511. The mounting component 513 includes a mounting arm 5131 and a fixed arm 5134. A connecting arm 5133 is provided between the movable end 5131a and the fixed end 5131b of the mounting arm 5131 to improve the stability and rigidity of the mounting arm 5131. Compared with the design of providing a connecting arm at the movable end in the third embodiment, this design can increase the space for the movable end to move up and down. The movable end 5131a of the mounting arm 5131 is provided with a ridge 5132, and the fixed end 5131b is fixed to the fixed arm 5134. And, as shown in FIG. Figure 46 As shown, there is a certain distance between the fixed end 5131b and the fixed arm 5134 in the height direction, which further increases the space for the movable end 5131a to move up and down.

[0173] like Figures 44-48 As shown, a mounting groove is provided in the first housing 51, which is connected to the first side wall and the second side wall of the first housing 51, and a terminal position ensuring mechanism 52 is inserted into the groove. Figure 45From the perspective of , the first side wall of the first shell 51 refers to the left side wall of the first shell 51, and the second side wall refers to the right side wall of the first shell 51. The terminal position ensuring mechanism 52 is cross-shaped, and is provided with an elastic support arm 523 and a second stop portion 522 that cooperate with the inner wall of the first shell 51, and a second matching portion 521 that cooperates with the first terminal. The elastic support arm 523 is provided at the second end of the terminal position ensuring mechanism 52. The second stop portion 522 is provided at the first end of the terminal position ensuring mechanism 52, and the first side wall of the first shell 51 is provided with a first stop portion (not shown in the figure), and the second stop portion 522 abuts against the first stop portion. The cooperation between the inner wall of the first shell 51 and the elastic support arm 523 can be referred to in the third embodiment and will not be repeated here. The second end of the terminal position ensuring mechanism 52 is also provided with an operating portion 524, and the operating portion 524 is exposed outside the mounting groove. Optionally, the size of the operating portion 524 is larger than the size of the mounting groove and will not enter the mounting groove. Unlike the third embodiment where the terminal position assurance mechanism is completely inserted into the installation slot and requires a tool to be removed, the terminal position assurance mechanism 52 of the fourth embodiment can be pulled out by directly grasping the operating portion 524, making the operation more convenient. The operating portion 524 does not protrude from the mounting component 513 in the width direction, avoiding interference with the mounting panel when the first electrical connector 5 is installed on the mounting panel. The width direction here refers to the width direction of the mounting panel. Figure 44 The left and right directions in the viewing angle. Figure 45 As shown, in the fourth embodiment, the shapes of the fixing arms 5134 of the left and right mounting components are different, which can achieve foolproofing. It should be noted that the cutouts of the mounting panels in each embodiment match the electrical connectors, which will not be described in detail here.

[0174] Figures 49-53 FIG. 5 shows the structure of the first electrical connector according to the fifth embodiment of the present application. Figure 49 and Figure 50 As shown, in the fifth embodiment, the first electrical connector 6 includes a first housing 61, a plurality of first terminals (not shown), and a plurality of first conductors 66 connected to the first terminals. The first housing 61 includes a front mating portion 611 and a flange 612. The front side of the front mating portion 611 includes a first mating surface 6111. The side surfaces of the front mating portion 611 are provided with a plurality of mounting components 613. The mounting components 613 include mounting arms 6131 and fixed arms 6134. A connecting arm 6133 is provided between the movable end 6131a and the fixed end 6131b of the mounting arm 6131. ​​The movable end 6131a of the mounting arm 6131 is provided with a ridge 6132, and the fixed end 6131b is fixed to the fixed arm 6134.

[0175] like Figures 49-52 As shown, a mounting groove is provided in the first housing 61, which is connected to the first side wall and the second side wall of the first housing 61, and a terminal position ensuring mechanism 62 is inserted into the groove. Figure 50From the perspective of , the first side wall is the left side wall of the first shell 61, and the second side wall is the right side wall of the first shell 61. The terminal position ensuring mechanism 62 is cross-shaped, and is provided with a second mating portion 621 that cooperates with the first terminal.
