[0023] Please refer to Figure 1 , Figure 2 and Figure 3The connector assembly 100 provided in the first embodiment of this application is used in an electrical control box 200. The connector assembly 100 includes a connector 10 and a mating connector 20. The connector 10 is fixedly connected to and electrically connected to the electrical control box 200, and the connector 10 is used to mate with the mating connector 20. The connector 10 includes a mounting base 11, a first core 12, a first terminal 13, a first snap-fit member 14, and a second snap-fit member 15. The first core 12 is disposed on one side of the mounting base 11 along the X-axis direction, and the first terminal 13 is disposed inside the first core 12. The first snap-fit member 14 is fixedly connected to the mounting base 11 to connect to the first core 12. The second snap-fit member 15 is fixedly connected to the mounting base 11 to connect to the first core 12. The first snap-fit member 14 and the second snap-fit member 15 are spaced apart from each other in the circumferential direction of the first core 12, and are spaced apart along the Y-axis direction. One end of the first core 12 is located between the first snap-fit member 14 and the second snap-fit member 15. The width (dimension along the Z-axis) of the first snap-fit member 14 is different from the width (dimension along the Z-axis) of the second snap-fit member 15. In this embodiment, the mounting base 11, the first adhesive core 12, the first snap-fit member 14, and the second snap-fit member 15 are integrally formed. In other embodiments, the mounting base 11, the first adhesive core 12, the first snap-fit member 14, and the second snap-fit member 15 can also be processed separately.
[0024] Understandably, the X-axis direction is the insertion direction of connector 10. The Y-axis direction is the width direction of connector 10, and the Y-axis is perpendicular to the X-axis. The Z-axis direction is the length direction of connector 10, and the Z-axis is perpendicular to both the X-axis and the Y-axis.
[0025] Please refer to Figure 2 and Figure 5 The connector 20 to be mated includes a second core 21, a second terminal 22, a first latching portion 23, a second latching portion 24, and a first overlay 25. The second terminal 22 is disposed within the second core 21. The first latching portion 23 and the second latching portion 24 are disposed on the outer peripheral surface of the second core 21. The first overlay 25 covers the end of the second core 21 away from the first latching portion 23 and the second latching portion 24.
[0026] Connector 10 is inserted into connector 20 to be mated. A second adhesive core 21 is fitted onto the first adhesive core 12. A second terminal 22 is inserted into the first terminal 13. A first snap-fit member 14 and a second snap-fit member 15 are inserted into connector 20 to be mated in one direction. The first snap-fit member 14 engages with the first latching part 23, and the second snap-fit member 15 engages with the second latching part 24. Connector 10 is a socket, and connector 20 to be mated is a plug. In other embodiments, connector 10 may also be a plug, and connector 20 to be mated may also be a socket.
[0027] In this embodiment, the first snap-fit member 14 snaps into the first snap-fit part 23, and the second snap-fit member 15 snaps into the second snap-fit part 24, thereby realizing the insertion of the first adhesive core 12 and the second adhesive core 21. The structure is simple and easy to assemble. Furthermore, the width of the first snap-fit member 14 is different from the width of the second snap-fit member 15. Users can determine the direction of connector 10 insertion by the width of the first snap-fit member 14 and the width of the second snap-fit member 15, which helps to prevent mistaken insertion and facilitates insertion and removal.
[0028] Please refer to Figure 2 , Figure 3 and Figure 4 In this embodiment, the mounting base 11 is plate-shaped and has a mounting surface 111, which is one end face of the mounting base 11 along the X-axis. The mounting surface 111 is provided with a boss 112, which includes a first connecting block 1121 disposed on the mounting surface 111 and two second connecting blocks 1122 connected to opposite sides of the first connecting block 1121. The side of the mounting base 11 facing away from the boss 112 is provided with a waterproof groove 113, and the mounting base 11 is provided with an adhesive filling hole 114 communicating with the waterproof groove 113.
[0029] One end of the first adhesive core 12 is connected to the first connecting block 1121 of the boss 112, and a waterproof step 1123 is formed between the first adhesive core 12 and the first connecting block 1121 of the boss 112. The other end of the first adhesive core 12 is located in the waterproof groove 113. Specifically, the first adhesive core 12 includes a first insertion end 121 and a first connecting end 122. The first insertion end 121 is connected to the first connecting block 1121 of the boss 112, and a waterproof step 1123 is formed between the first insertion end 121 and the first connecting block 1121. The outer peripheral surface of the first insertion end 121 of the first rubber core 12 is provided with a first sealing groove 1211 and a second sealing groove 1212. The first sealing groove 1211 and the second sealing groove 1212 are both arranged around the outer peripheral surface of the first insertion end 121 of the first rubber core 12. The first sealing groove 1211 and the second sealing groove 1212 are spaced apart in the axial direction (X-axis direction) of the first rubber core 12. The second sealing groove 1212 is closer to the waterproof step 1123 than the first sealing groove 1211.
[0030] The first connecting end 122 is partially located within the waterproof groove 113, and the end face of the first connecting end 122 facing away from the first plug-in end 121 has an inner cavity 1221. The outer peripheral surface of the first connecting end 122 has an adhesive inlet notch 1222, which connects the inner cavity 1221 and the waterproof groove 113. One end of each of the plurality of first terminals 13 is located within the first plug-in end 121, and the other end of each of the plurality of first terminals 13 is partially located within the inner cavity 1221 of the first connecting end 122.
[0031] In this embodiment, after the connector 10 is assembled, waterproof adhesive is filled from the potting hole 114 into the waterproof groove 113 and the inner cavity 1221 of the first adhesive core 12. Specifically, the waterproof adhesive flows from the potting hole 114 into the waterproof groove 113, and the waterproof adhesive that enters the waterproof groove 113 then flows into the inner cavity 1221 from the injection notch 1222, thereby improving the waterproof performance of the connector 10.
[0032] A foolproof key 1223 is provided on the end face of the first connecting end 122 facing away from the first plug-in end 121. Multiple baffles 115 are also provided on the side of the mounting base 11 facing away from the first plug-in end 121. These baffles 115 surround the mounting base 11 and are used to insert into the external electrical control box 200, thereby fixing the connector 10 to the electrical control box 200. The foolproof key 1223 prevents the connector 10 from being fixedly connected to the electrical control box 200.
[0033] The first snap-fit component 14 includes a flexible first cantilever 141 and a first buckle 142. One end of the first cantilever 141 is connected to one of the second connecting blocks 1122. The first buckle 142 is located at the end of the first cantilever 141 away from the boss 112, and is situated on the side of the first cantilever 141 facing the first rubber core 12. The second snap-fit component 15 includes a flexible second cantilever 151 and a second buckle 152. One end of the second cantilever 151 is connected to another second connecting block 1122. The second buckle 152 is located at the end of the second cantilever 151 away from the boss 112, and is situated on the side of the second cantilever 151 facing the first rubber core 12.
[0034] The connector 10 also includes a first sealing ring 16 and a second sealing ring 17. The first sealing ring 16 is sleeved on the outer peripheral surface of the first rubber core 12, and the second sealing ring 17 is sleeved on the outer peripheral surface of the first rubber core 12. Specifically, the first sealing ring 16 is positioned in the first sealing groove 1211, and the second sealing ring 17 is positioned in the second sealing groove 1212, with the second sealing ring 17 facing the waterproof step 1123. By positioning the first sealing ring 16 in the first sealing groove 1211 and the second sealing ring 17 in the second sealing groove 1212, the first sealing ring 16 and the second sealing ring 17 can be more stably installed on the first rubber core 12, thereby improving the sealing performance.
[0035] Please refer to Figure 2 and Figure 5 In this embodiment, the second core 21 includes a second plug-in end 211 and a second connecting end (not shown in the figure, the second connecting end is covered by the first adhesive 25) that are fixedly connected. The end face of the second plug-in end 211 opposite to the second connecting end is provided with a plug-in cavity 2111. One end of a plurality of second terminals 22 is located in the plug-in cavity 2111, and the other end of the plurality of second terminals 22 is located in the second connecting end.
[0036] In this embodiment, both the first latching part 23 and the second latching part 24 are block-shaped. The first latching part 23 is disposed on the outer peripheral surface of the second insertion end 211 of the second adhesive core 21, and the second latching part 24 is disposed on the outer peripheral surface of the second insertion end 211 of the second adhesive core 21. The first latching part 23 and the second latching part 24 are arranged opposite to each other along the Y-axis direction, and are symmetrically arranged. The circumferential length of the first latching part 23 along the second insertion end 211 of the second adhesive core 21 is different from the circumferential length of the second latching part 24 along the second adhesive core 21.
[0037] The outer peripheral surface of the second insertion end 211 of the second core 21 is also provided with a first guide structure 212 and a second guide structure 213, which are arranged opposite to each other along the Y-axis. The first guide structure 212 is provided with a first guide groove 2121 facing the first snap-fit part 23, and the second guide structure 213 is provided with a second guide groove 2131 facing the second snap-fit part 24. The width (dimension along the Z-axis) of the first guide groove 2121 is different from the width (dimension along the Z-axis) of the second guide groove 2131.
[0038] Specifically, the first guide structure 212 includes a first guide plate 2122 and a second guide plate 2123 spaced apart along the Z-axis, with the gap between the first guide plate 2122 and the second guide plate 2123 forming a first guide groove 2121. The second guide structure 213 includes a third guide plate 2132 and a fourth guide plate 2133 spaced apart along the Z-axis, with the gap between the third guide plate 2132 and the fourth guide plate 2133 forming a second guide groove 2131.
[0039] Please refer to Figure 4 , Figure 5 and Figure 6 In this embodiment, when the connector 10 is inserted into the connector 20 to be mated, the first snap-fit member 14 can snap onto the first snap-fit part 23 along the first guide groove 2121, and the second snap-fit member 15 can snap onto the second snap-fit part 24 along the second guide groove 2131. Specifically, the first snap-fit 142 of the first snap-fit member 14 abuts against the first snap-fit part 23 and moves toward the connector 20 to be mated. The first cantilever 141 expands outward under force. The first snap-fit 142 moves to the side of the first snap-fit part 23 away from the connector 10. The first cantilever 141 rebounds, so that the first snap-fit 142 snaps into the side of the first snap-fit part 23 away from the connector 10. The second latch 152 of the second latching member 15 abuts against the second latching part 24 and moves toward the connector 20 to be mated. The second cantilever 151 expands outward under force. The second latch 152 continues to move to the side of the second latching part 24 away from the connector 10. The second cantilever 151 rebounds, so that the second latch 152 is engaged in the side of the second latching part 24 away from the connector 10.
[0040] Meanwhile, the second insertion end 211 of the second rubber core 21 is sleeved on the first insertion end 121 of the first rubber core 12, the first terminal 13 and the second terminal 22 are inserted into each other, and the second insertion end 211 of the second rubber core 21 and the first insertion end 121 of the first rubber core 12 sealably clamp the first sealing ring 16. The second insertion end 211 of the second rubber core 21 and the waterproof step 1123 seal the second sealing ring 17. The first rubber core 12 and the second rubber core 21 have a two-stage waterproofing, resulting in better waterproofing performance. Furthermore, when the second sealing ring 17 is compressed, it generates elastic forces on the connector 10 and the connector 20 to be mated, respectively. The two elastic forces are in opposite directions, causing the connector 10 and the connector 20 to have a tendency to move in opposite directions. This keeps the first latch 142 of the connector 10 and the first latch portion 23 of the connector 20 to be mated in abutting state, and the second latch 152 of the connector 10 and the second latch portion 24 of the connector 20 to be mated in abutting state. This prevents the connector 10 and the connector 20 from loosening when they are in the insertion state, and improves the stability of the insertion of the connector 10 and the connector 20.
[0041] In this embodiment, by setting a first guide structure 212 and a second guide structure 213, the first guide structure 212 and the second guide structure 213 respectively guide the first snap-fit member 14 and the second snap-fit member 15, which facilitates insertion.
[0042] In this embodiment, the width (dimension along the Z-axis) of the first latching member 14 is different from the width (dimension along the Z-axis) of the second latching member 15. The circumferential length of the first latching portion 23 along the second insertion end 211 of the second adhesive core 21 is different from the circumferential length of the second latching portion 24 along the second adhesive core 21. The width (dimension along the Z-axis) of the first guide groove 2121 is different from the width (dimension along the Z-axis) of the second guide groove 2131. The width of the first latching member 14 is smaller than the width of the first guide groove 2121, and the width of the second latching member 15 is smaller than the width of the second guide groove 2131. Furthermore, the width of the first latching member 14 is greater than the width of the second guide groove 2131, so that the first latching member 14 can only pass through the first guide groove 2121 and cannot pass through the second guide groove 2131. This limits the direction of insertion of the connector to be mated 20 and the connector 10, which is beneficial for preventing mistaken insertion.
[0043] In this embodiment, the mounting surface 111 can be used to set the logo. By setting the first snap-fit 14, the second snap-fit 15 and the first adhesive core 12 on the boss 112, the first snap-fit 14, the second snap-fit 15 and the first adhesive core 12 are all isolated from the mounting surface 111. When the mold processes the first snap-fit 14, the second snap-fit 15 and the first adhesive core 12, it will not affect the appearance of the logo.
[0044] Please refer to Figure 6 In this embodiment, if it is necessary to remove the connector 20 to be mated, a disassembly jig 300 can be used to assist in disassembly. For example, in Figure 1 In confined spaces such as the electrical control box 200, when users cannot reach into the confined space to disassemble the device by hand, a disassembly jig 300 can be used to assist in disassembly. Specifically, the disassembly jig 300 is U-shaped and includes a main body 310, a first abutment plate 320, and a second abutment plate 330. Both the first abutment plate 320 and the second abutment plate 330 are fixedly connected to one side of the main body 310 along its thickness direction. The first abutment plate 320 and the second abutment plate 330 are spaced apart.
[0045] When disassembling the connector 20 to be mated, the disassembly jig 300 is fitted onto the first adhesive 25. The end of the first abutment plate 320 away from the main body 310 faces the first snap-fit member 14, and the end of the second abutment plate 330 away from the main body 310 faces the second snap-fit member 15. The main body 310 is pushed toward the connector 10, so that the first abutment plate 320 abuts against the first snap 142 of the first snap-fit member 14, and the second abutment plate 330 abuts against the second snap 152 of the second snap-fit member 15. The first cantilever 141 and the second cantilever 151 are forced to expand outward, thereby causing the first snap 142 and the second snap 152 to disengage from the first snap-fit part 23 and the second snap-fit part 24, respectively. At this time, the connector 20 to be mated can be pulled out.
[0046] Please refer to Figure 7 The connector assembly 100 provided in the second embodiment of this application has a structure similar to that of the connector assembly 100 provided in the first embodiment. The main difference is that the mounting base 11 of the connector 10 in the second embodiment does not have a baffle 115, and the connector 10 also includes a second coating 18, which covers the first connecting end 122 of the first core 12 and extends along the X-axis. The technical effects of the connector assembly 100 in the second embodiment are similar to those in the first embodiment, and will not be described in detail here. Both can meet the needs of different application scenarios. For example, in the connector assembly 100 of the first embodiment, the connector 10 is used to be installed in the electrical control box 200, and the connector to be paired 20 is used to connect with external cables. When the connector 10 and the connector to be paired 20 are plugged in, an electrical connection between the external cables and the electrical control box 200 can be achieved. In the connector assembly 100 of the second embodiment, the connector 10 and the connector to be paired 20 are respectively used to connect with two external cables. When the connector 10 and the connector to be paired 20 are plugged in, an electrical connection between the two external cables can be achieved.
[0047] Please refer to Figure 8 and Figure 9The connector assembly 100 provided in the third embodiment of this application has a similar structure to the connector assembly 100 provided in the first embodiment. The main difference is that in the connector 10 of the third embodiment, the mounting base 11 does not have a boss 112. The first insertion end 121 of the first core 12, the first snap-fit member 14, and the second snap-fit member 15 are all disposed on the mounting surface 111 of the mounting base 11. The first snap-fit 142 is disposed on the side of the first cantilever 141 away from the first core 12, and the second snap-fit 152 is disposed on the side of the second cantilever 151 away from the first core 12. The mounting base 11 also has two first isolation members 116 and two second isolation members 117. The two first isolation members 116 are respectively located on both sides of the first snap-fit member 14 along the Z-axis direction, and the two second isolation members 117 are respectively located on both sides of the second snap-fit member 15 along the Z-axis direction. The two first isolation members 116 protect the first snap-fit member 14, and the two second isolation members 117 protect the second snap-fit member 15.
[0048] In addition, the first latching part 23 of the third embodiment includes a first support body 231, a first mating body 232, and a first pressing body 233. The first support body 231 is disposed on the outer peripheral surface of the second adhesive core 21, the first mating body 232 is disposed on the side of the first support body 231 facing the first latching member 14, and the first pressing body 233 is disposed on the side of the first support body 231 away from the first mating body 232. Specifically, both the first support body 231 and the first pressing body 233 are plate-shaped. The first mating body 232 includes a third cantilever 2321 and a third latch 2322. One end of the third cantilever 2321 is fixedly connected to the first support body 231, and the third latch 2322 is fixedly connected to the end of the third cantilever 2321 away from the first support body 231. The third latch 2322 is located on the side of the third cantilever 2321 facing the second adhesive core 21.
[0049] The second latching part 24 of the third embodiment includes a second support body 241, a second mating body 242, and a second pressing body 243. The second support body 241 is disposed on the outer peripheral surface of the second core 21, the second mating body 242 is disposed on the side of the second support body 241 facing the second latching member 15, and the second pressing body 243 is disposed on the side of the second support body 241 away from the second mating body 242. Specifically, both the second support body 241 and the second pressing body 243 are plate-shaped. The second mating body 242 includes a fourth cantilever 2421 and a fourth latch 2422. One end of the fourth cantilever 2421 is fixedly connected to the second support body 241, and the fourth latch 2422 is fixedly connected to the end of the fourth cantilever 2421 away from the second support body 241. The fourth latch 2422 is located on the side of the fourth cantilever 2421 facing the second core 21.
[0050] When connector 10 is inserted into connector 20, the first latching member 14 latches with the first mating body 232, and the second latching member 15 latches with the second mating body 242. Specifically, the first latch 142 of the first latching member 14 abuts against the third latch 2322 of the first mating body 232 and moves toward connector 20. The first cantilever 141 contracts inward under force, and the third cantilever 2321 expands outward under force. When the first latch 142 moves to the side of the third latch 2322 facing away from connector 10, both the first cantilever 141 and the third cantilever 2321 spring back, causing the first latch 142 to engage with the side of the third latch 2322 facing away from connector 10.
[0051] The second latch 152 of the second latching member 15 abuts against the fourth latch 2422 of the second mating body 242 and moves toward the connector 20 to be mated. The second cantilever 151 is forced to retract inward, and the fourth cantilever 2421 is forced to expand outward. When the second latch 152 moves to the side of the fourth latch 2422 facing away from the connector 10, both the second cantilever 151 and the fourth cantilever 2421 spring back, causing the second latch 152 to engage with the side of the fourth latch 2422 facing away from the connector 10.
[0052] In this embodiment, if the user needs to remove the connector 20 to be mated, they can first press the first pressing body 233 and the second pressing body 243, and then remove the connector 20 to be mated. Specifically, pressing the first pressing body 233 and the second pressing body 243 causes the third cantilever 2321 and the fourth cantilever 2421 to expand outwards, the third latch 2322 to move away from the first latch 142, and the fourth latch 2422 to move away from the second latch 152, at which point the connector 20 to be mated can be removed.
[0053] In this embodiment, by setting the first snap-fit member 14 to snap-fit with the first mating body 232, and the second snap-fit member 15 to snap-fit with the second mating body 242, a fixed connection between the connector 10 and the connector to be mated 20 is achieved, making assembly convenient. Furthermore, the connector to be mated 20 can be easily removed by pressing the first pressing body 233 and the second pressing body 243.
[0054] Please refer to Figure 10 , Figure 11 and Figure 12 The connector assembly 100 provided in the fourth embodiment of this application has a similar structure to the connector assembly 100 provided in the third embodiment. The main difference is that in the connector 20 to be mated in the fourth embodiment, the first snap-fit portion 23 is cylindrical, and the first snap-fit portion 23 is provided with a first snap-fit hole 234 and a first snap-fit groove 235. The first snap-fit hole 234 penetrates the first snap-fit portion 23 along the insertion direction (X-axis direction) of the connector 10. The first snap-fit groove 235 is provided at one end of the first snap-fit portion 23 away from the first snap-fit member 14, and the first snap-fit groove 235 communicates with the first snap-fit hole 234.
[0055] The second latching part 24 is symmetrically arranged with the first latching part 23. The second latching part 24 is cylindrical and has a second latching hole 244 and a second latching groove 245. The second latching hole 244 passes through the second latching part 24 along the insertion direction (X-axis direction) of the connector 10. The second latching groove 245 is located at one end of the second latching part 24 away from the second latching member 15 and communicates with the second latching hole 244.
[0056] When connector 10 is inserted into connector 20 to be mated, first snap-fit member 14 passes through first snap-fit hole 234 and snaps into first snap-fit groove 235; second snap-fit member 15 passes through second snap-fit hole 244 and snaps into second snap-fit groove 245. Specifically, the first latch 142 of the first snap-fit member 14 abuts against the side wall of the first snap-fit hole 234 and moves toward connector 20 to be mated. The first cantilever 141 of the first snap-fit member 14 is forced to retract inward. When the first latch 142 moves to the area of the first snap-fit groove 235, the first cantilever 141 springs back, and the first latch 142 snaps into the first snap-fit groove 235, with the first latch 142 abutting against the bottom surface of the groove 235.
[0057] The second latch 152 of the second latching member 15 abuts against the side wall of the second latching hole 244 and moves toward the connector 20 to be mated. The second cantilever 151 of the second latching member 15 is forced to retract inward. When the second latch 152 moves to the area of the second latching groove 245, the second cantilever 151 rebounds and the second latch 152 is engaged in the second latching groove 245. The second latch 152 abuts against the bottom surface of the groove of the second latching groove 245.
[0058] In this embodiment, by setting the first latching part 23 and the second latching part 24 as a cylindrical structure, when the connector 10 is inserted into the connector 20 to be paired, the first latching member 14 is housed in the first latching part 23 and the second latching member 15 is housed in the second latching part 24. The structure is compact and conducive to the miniaturization design of the product.
