Description

Technical Field

[0001] This invention relates to a mating connector and an electrical connector assembly, belonging to the field of connector technology. Background Technology

[0002] Please combine Figure 1 as well as Figure 2 As shown, electrical connector assemblies in related technologies typically include a first circuit board 300", a mating connector 200" mounted on the first circuit board 300", and a first electrical connector 100 that plugs into the mating connector 200". The mating connector 200" is provided with a mating slot 8120. The first electrical connector 100" includes a first tongue plate 12", a first positioning plate 13" protruding from the first tongue plate 12", and a plurality of first cables 5". The first positioning plate 13" is used to mate with the positioning slot of the mating connector 200" at a fixed angle. Please refer to... Figure 1 As shown, when the mating connector 200” is inserted into the first electrical connector 100”, its state is as follows. Figure 1 The electrical connector assembly is shown on the left.

[0003] With the continuous increase in installation requirements, Figure 1 In some cases, the left-hand mating connector 200” needs to be rotated 180° before being mounted on the second circuit board 300”'. In other words, the structure of the mating connector 200” itself remains unchanged; only the mounting angle is rotated 180°. Those skilled in the art will understand that, in this case, correspondingly, with… Figure 1 The outgoing direction of the first cable 5” of the first electrical connector 100” to which the right-side mating connector 200” is plugged will inevitably be opposite to the outgoing direction of the first cable 5” of the first electrical connector 100” to which the left-side mating connector 200” is plugged. To arrange the first cables 5” of the two first electrical connectors 100” together as much as possible, such as... Figure 1 As shown, the related technology proposes to fold the first cable 5” of the first electrical connector 100” on the right side in the opposite direction so that the first cables 5” of the two first electrical connectors 100” are as close as possible.

[0004] However, due to the reverse folding of the first cable 5", the overall height of the electrical connector assembly is relatively high, and the reverse folding is prone to damaging the first cable 5".

[0005] Therefore, it is necessary to improve the mating connectors and electrical connector assemblies in the relevant technologies. Summary of the Invention

In this invention, the term "several" means two or more.

[0104] Please refer to Figures 3 to 17 as well as Figure 18 and Figure 19 As shown, a first embodiment of the present invention discloses an electrical connector assembly, comprising a first electrical connector 100, a mating connector 200 corresponding to the first electrical connector 100, a second electrical connector 100', and another mating connector 200' corresponding to the second electrical connector 100'. In the illustrated embodiment of the present invention, the first electrical connector 100 and the second electrical connector 100' are pull-tab connectors and cable connectors, the mating connector 200 is a board-end connector for mounting to a first circuit board 300 in a first position, and the other mating connector 200' is a board-end connector for mounting to a second circuit board 300' in a second position. Please refer to... Figure 6 As shown, the first electrical connector 100 is used to mate with the mating connector 200 along the mating direction B (e.g., from top to bottom) to enable data transmission. Please refer to... Figure 18 As shown, the second electrical connector 100' is used to mate with the other mating connector 200' along the mating direction B (e.g., from top to bottom) to enable data transmission.

[0105] In the embodiment illustrated in the present invention, the mating connector 200 and the other mating connector 200' are connectors with the same structure, except that their installation angles differ by 180°. In other words, it can be understood that the other mating connector 200' is formed by rotating the mating connector 200 by 180° in the plane where the circuit board is located.

[0106] The first circuit board 300 and the second circuit board 300' can be the same or different circuit boards. When the first circuit board 300 and the second circuit board 300' are the same circuit board, they are the same circuit board.

[0107] The following description uses the first electrical connector 100, the mating connector 200, and the first circuit board 300 as examples. Please refer to... Figures 5 to 17 As shown, the first electrical connector 100 includes a first insulating body 1, a plurality of first conductive terminals 2 fixed to the first insulating body 1, a first movable part 3 mounted on the first insulating body 1, a first elastic member 4 for abutting against the first movable part 3, a first cable 5 electrically connected to the first conductive terminals 2, a first cover plate 6 fastened to the first insulating body 1 and at least partially abutting against the first cable 5, and a first pull strap 7 connected to the first movable part 3. The first pull strap 7 is configured to drive the first movable part 3 to overcome the force of the first elastic member 4, causing the first movable part 3 to move in a direction C perpendicular to the mating direction B (see reference). Figure 5 (As shown).

[0108] In the illustrated embodiment of the present invention, the first insulating body 1 includes a first main body portion 11, a first tongue plate 12 protruding downward from the first main body portion 11 along the mating direction B, and a first positioning plate 13 further protruding downward from the first tongue plate 12 along the mating direction B. In the illustrated embodiment of the present invention, the dimensions of the first main body portion 11 along the front-rear / second direction, the dimensions of the first tongue plate 12 along the front-rear direction, and the dimensions of the first positioning plate 13 along the front-rear direction successively decrease, thereby making the first insulating body 1 substantially stepped. Please refer to the illustrated embodiment of the present invention. Figure 6 and Figure 7As shown, the first positioning plate 13 includes a first positioning piece 131 located in the middle, a second positioning piece 132 located on one side of the first positioning piece 131 and spaced apart from it, and a third positioning piece 133 located on the other side of the first positioning piece 131 and spaced apart from it. The dimension of the first positioning piece 131 in the left-right direction / first direction is larger than the dimension of the second positioning piece 132 in the left-right direction, and the dimension of the first positioning piece 131 in the left-right direction is also larger than the dimension of the third positioning piece 133 in the left-right direction. In the embodiment illustrated in the present invention, the distance between the first positioning piece 131 and the second positioning piece 132 is different from the distance between the first positioning piece 131 and the third positioning piece 133. This arrangement can play a certain role in preventing mistaken insertion, preventing the first electrical connector 100 from being inserted into the mating connector 200 at an incorrect angle.

The first main body 11 also includes a fixing plate 117 located between the first end wall 111 and the second end wall 112. In the embodiment illustrated in the present invention, the fixing plate 117 is a vertical plate. The fixing plate 117 includes a pull strap groove 1170 extending along the moving direction C and a pull strap shaft 1171 located between the edge (e.g., the upper edge) of the fixing plate 117 and the pull strap groove 1170. The first pull strap 7 extends from its connection with the first movable member 3 along the moving direction C through the pull strap groove 1170, and extends out of the first main body 11 after bending around the pull strap shaft 1171. The fixing plate 117 further includes receiving holes 1172. In the embodiment illustrated in the present invention, there are two receiving holes 1172. The receiving holes 1172 are recessed in the surface of the fixing plate 117 facing the first movable component 3, that is, the receiving holes 1172 are exposed on the surface of the fixing plate 117 facing the first movable component 3. One end of the first elastic member 4 is disposed in the receiving hole 1172, and the other end of the first elastic member 4 abuts against the first movable component 3.

In the embodiment illustrated in the present invention, the mating portion 21 is flat and exposed on the first surface 121 and the second surface 122, respectively. In one embodiment of the present invention, the first conductive terminal 2 is embedded in the first insulating body 1. Of course, in other embodiments, the first conductive terminal 2 can also be directly installed on the first insulating body 1; or the first conductive terminal 2 and the insulating block can be first combined into a terminal module and then installed on the first insulating body 1. The method of fixing the first conductive terminal 2 to the first insulating body 1 is well known to those skilled in the art, and will not be described in detail here.

[0113] In the embodiment illustrated in the present invention, the first cable 5 extends beyond the first main body portion 11 along the moving direction C.

[0114] Please refer to Figure 10 and Figure 14 As shown, the first movable component 3 is at least partially installed in the first main body portion 11. Specifically, the first movable component 3 includes a base 31 received in the receiving space 110, a first push rod 32 extending rearward from one side of the base 31 and received in the first receiving groove 113 with its rear end extending out of the first receiving groove 113, and a second push rod 33 extending rearward from the other side of the base 31 and received in the second receiving groove 114 with its rear end extending out of the second receiving groove 114. Both the first push rod 32 and the second push rod 33 can be referred to as push rods extending from the first end wall 111 to the second end wall 112 and with their rear ends protruding out of the second end wall 112.

[0115] The base 31 is provided with a first locking protrusion 301, which protrudes forward from the first end wall 111. In the illustrated embodiment of the present invention, there are two first locking protrusions 301, located on both sides of the base 31 (e.g., the left and right sides), to improve the engagement retention force. In the illustrated embodiment of the present invention, the first locking protrusion 301 is integrally formed with the first main body 11. Of course, in other embodiments, the first locking protrusion 301 can also be manufactured separately from the first main body 11 and then assembled and fixed together. In this case, the first locking protrusion 301 can be made of a different material than the first main body 11, such as a wear-resistant material with good structural strength. The base 31 is also provided with a pull strap connecting portion 312, and the first pull strap 7 is connected to the pull strap connecting portion 312. The first movable member 3 includes a through groove 311 extending through the base 31 along the moving direction C. The pull strap connecting portion 312 is located above the through groove 311. The pull strap connection portion 312 resembles a shaft portion and is located between the through groove 311 and the edge (e.g., the upper edge) of the base portion 31. One end of the first pull strap 7 passes through the through groove 311 and is sleeved around the pull strap connection portion 312.

[0116] In the embodiment illustrated in the present invention, the first elastic member 4 is a compression spring installed between the base 31 and the inner wall surface 115 of the first main body 11. Two compression springs are arranged side-by-side to improve the smoothness of movement of the first movable member 3. Furthermore, to better position the compression spring, the base 31 is also provided with a positioning post 313 that is at least partially inserted into the compression spring (see reference). Figure 12 (As shown).

[0117] The first movable component 3 also includes a second locking protrusion 302 that protrudes rearward from the second end wall 112. In the embodiment illustrated in the present invention, there are two second locking protrusions 302. One second locking protrusion 302 is located at the rear end of the first push rod 32 away from the base 31 and is located outside the first receiving groove 113 and protrudes towards the first receiving groove 113. The other second locking protrusion 302 is located at the rear end of the second push rod 33 away from the base 31 and is located outside the second receiving groove 114 and protrudes towards the second receiving groove 114, thereby improving the docking retention force. In the embodiment illustrated in the present invention, the second locking protrusion 302 and the corresponding push rod are integrally formed to save costs. Of course, in other embodiments, the second locking protrusion 302 can also be manufactured separately from the corresponding push rod and then assembled and fixed together. In this case, the second locking protrusion 302 can be made of a different material than the push rod. The first locking protrusion 301 and the second locking protrusion 302 are used to lock with the locking hole of the mating connector 200 to improve the mating retention force (details to follow).

[0118] Please refer to Figure 10 , Figure 11 and Figure 14 As shown, the first push rod 32 includes a first limiting groove 320 located in the middle, a first limiting surface 321 located at one end of the first limiting groove 320 along the moving direction C, and a second limiting surface 322 located at the other end of the first limiting groove 320 along the moving direction C. The first limiting surface 321 is closer to the first end wall 111 than the second limiting surface 322.

[0119] Similarly, the second push rod 33 includes a second limiting groove 330 located in the middle, a third limiting surface 331 located at one end of the second limiting groove 330 along the moving direction C, and a fourth limiting surface 332 located at the other end of the second limiting groove 330 along the moving direction C. The third limiting surface 331 is closer to the first end wall 111 than the fourth limiting surface 332.

[0120] Please refer to Figure 10 , Figure 11 and Figure 14As shown, the first push rod 32 further includes a first groove 324 located at its end (rear end), and the second push rod 33 further includes a second groove 334 located at its end (rear end). Both the first groove 324 and the second groove 334 can be referred to as slots. Each slot has a first baffle 303 (e.g., a rear baffle), a second baffle 304 (e.g., a lower front baffle) disposed below and facing the first baffle 303, and a third baffle 305 (e.g., an upper front baffle) disposed above and facing the first baffle 303. A large-diameter portion (unlabeled) is formed between the first baffle 303 and the lower second baffle 304, and a small-diameter portion (unlabeled) is formed between the first baffle 303 and the upper third baffle 305. As the name suggests, the size of the upper small-diameter portion in the front-rear direction is smaller than the size of the lower large-diameter portion in the front-rear direction. It should be emphasized that in this embodiment, the groove is a through groove that includes an upper small diameter portion and a lower large diameter portion, and the small diameter portion exists due to the manufacturing process of the groove. In other embodiments, the groove may not have an upper small diameter portion and may only include a lower large diameter portion, so that when the insert plate portion 8321 is received in the groove that only includes the lower large diameter portion, the groove moves in the front-back direction with the first movable component 3, so that the second locking protrusion 302 can be inserted into the second locking hole 8322 on the insert plate portion 8321 to engage.

[0121] The second latching protrusion 302 protrudes from below the first stop wall 303 toward the second stop wall 304 and is spaced a distance from the second stop wall 304. Therefore, the first latching protrusion 301 also protrudes from back to front, so that the first latching protrusion 301 and the second latching protrusion 302 in this invention have the same forward protruding direction. Figure 6 , Figure 9 and Figure 10 It can be seen that the forward protrusion direction is opposite to the direction of movement C.

[0122] The first electrical connector 100 includes a first pin 161 and a second pin 162 fixed in the first mounting hole 1161 and the second mounting hole 1162. The first pin 161 is inserted into the first limiting groove 320, and the second pin 162 is inserted into the second limiting groove 330. The dimension of the first limiting groove 320 along the moving direction C is larger than the dimension of the first pin 161 along the moving direction C. The dimension of the second limiting groove 330 along the moving direction C is larger than the dimension of the second pin 162 along the moving direction C. The first limiting surface 321 abuts against the first pin 161, and the third limiting surface 331 abuts against the second pin 162 to prevent the first movable component 3 from moving excessively along the moving direction C under the action of the first pull strap 7; the second limiting surface 322 abuts against the first pin 161, and the fourth limiting surface 332 abuts against the second pin 162 to prevent the first movable component 3 from excessively returning to its original position in the opposite direction to the moving direction C when the first elastic member 4 releases its restoring force.

[0123] The first cover plate 6 is received and fixed in the opening 1160 of the first main body 11, and the first pull strap 7 extends out of the first cover plate 6. In one embodiment of the invention, the first cover plate 6 presses against the connection between the first cable 5 and the first conductive terminal 2 (e.g., the welded part of the two) to provide protection.

[0124] Please refer to Figures 4 to 10 as well as Figure 15 As shown, the mating connector 200 includes a mating insulating body 81, a plurality of mating terminals 82 fixed to the mating insulating body 81, and a metal housing 83 covering the mating insulating body 81. The mating insulating body 81 includes a bottom wall 811 and a plurality of wall portions 812 perpendicular to the bottom wall 811. Please refer to... Figure 7 As shown, the bottom wall 811 is provided with a positioning groove 8110 for receiving the first positioning plate 13. Specifically, the positioning groove 8110 includes a first positioning groove 8111 for receiving the first positioning piece 131, a second positioning groove 8112 for receiving the second positioning piece 132, and a third positioning groove 8113 for receiving the third positioning piece 133. In the embodiment illustrated in the present invention, the first positioning groove 8111, the second positioning groove 8112, and the third positioning groove 8113 penetrate the bottom wall 811.

[0125] Please refer to Figure 15 and Figure 16As shown, the mating connector 200 further includes a terminal fixing block 84, on which the plurality of mating terminals 82 are fixed; the mating insulating body 81 further includes a terminal receiving groove 813, in which the terminal fixing block 84 is fixed. In some embodiments, the terminal fixing block 84 includes a first engaging portion 841, and one side of the terminal receiving groove 813 includes a second engaging portion 8131, the first engaging portion 841 and the second engaging portion 8131 engaging with each other, thereby fixing the terminal fixing block 84 in the terminal receiving groove 813. In some embodiments, the first engaging portion 841 is a dovetail-shaped protrusion, and the second engaging portion 8131 is a dovetail-shaped groove that matches the dovetail-shaped protrusion.

[0126] In some embodiments, there are two terminal fixing blocks 84, which are symmetrically arranged and spaced apart. The plurality of mating terminals 82 are configured in two symmetrical rows, and the two rows of mating terminals 82 are respectively fixed to the two terminal fixing blocks 84. There are two terminal receiving slots 813, which are symmetrically arranged and spaced apart. The two terminal receiving slots 813 are respectively formed between the bottom wall 811 and two opposing wall portions 812. The two terminal fixing blocks 84 are fixed in the two terminal receiving slots 813. In some embodiments, each terminal fixing block 84 includes a plurality of first engaging portions 841, and one side of each terminal receiving slot 813 includes a plurality of second engaging portions 8131 corresponding to the plurality of first engaging portions 841. Each first engaging portion 841 and its corresponding second engaging portion 8131 engage with each other, so that each terminal fixing block 84 is fixed in its corresponding terminal receiving slot 813. In some embodiments, the plurality of first snap-fit ​​portions 841 are respectively disposed on one side of the two terminal fixing blocks 84 facing each other, and the plurality of second snap-fit ​​portions 8131 are respectively disposed on opposite sides of the bottom wall 811 facing the two terminal receiving grooves 813.

[0127] Please refer to Figure 10 and Figure 15 As shown, the plurality of wall portions 812 form a mating slot 8120 for receiving the first tongue plate 12. The mating terminals 82 are arranged in two rows, and each mating terminal 82 includes a resilient mating arm 821 and a mounting tail 822 for mounting to the first circuit board 300. The resilient mating arm 821 extends into the mating slot 8120 and is used to contact the mating portion 21.

[0128] The metal casing 83 includes a first sidewall 831, a second sidewall 832 opposite to the first sidewall 831, a first connecting wall 833 connecting one side of the first sidewall 831 and one side of the second sidewall 832, and a second connecting wall 834 connecting the other side of the first sidewall 831 and the other side of the second sidewall 832. The first sidewall 831 has a first latching hole 8311 that mates with the first latching protrusion 301. The second sidewall 832 has an insert plate portion 8321 on each of its left and right sides, near the corners of the first connecting wall 833 and the second connecting wall 834, respectively. Each insert plate portion 8321 has a second latching hole 8322 that mates with the second latching protrusion 302. In the embodiment illustrated in the present invention, the insert plate portion 8321 is integrally formed on the second side wall 832. The insert plate portion 8321 and the first connecting wall 833, as well as the insert plate portion 8321 and the second connecting wall 834, are also integrally formed without gaps. Therefore, the insert plate portion 8321 is not elastic.

[0129] When the first electrical connector 100 is inserted into the mating connector 200, the first positioning plate 13 corresponds to the positioning groove 8110, the first tongue plate 12 corresponds to the mating slot 8120, and the mating portion 21 of the first conductive terminal 2 corresponds to the elastic mating arm 821 of the mating terminal 82. As the first electrical connector 100 is inserted, the inclined surfaces of the first locking protrusion 301 and the second locking protrusion 302 abut against the first sidewall 831 and the second sidewall 832, respectively. The first movable component 3 overcomes the force of the first elastic member 4 and retracts inward a certain distance along the moving direction C. When the first locking protrusion 301 and the second locking protrusion 302 move downward to correspond to the first locking hole 8311 and the second locking hole 8322, the first elastic member 4 returns to its original position, causing the first movable component 3 to return to its original position in the opposite direction to the moving direction C. At this time, the first locking protrusion 301 and the second locking protrusion 302 both protrude forward into the first locking hole 8311 and the second locking hole 8322 to achieve the locking of the first electrical connector 100 and the mating connector 200.

[0130] By providing the first locking protrusion 301 and the second locking protrusion 302 located on both sides, the present invention can achieve double-sided locking in the front-back direction / second direction, thereby improving the docking reliability and reducing the risk of loosening or tilting between the first electrical connector 100 and the docking connector 200.

[0131] When unlocking is required, an external force is applied to pull the first pull strap 7. The first pull strap 7 generates a component force along the movement direction C. This component force overcomes the force of the first elastic member 4, causing the first movable part 3 to move along the movement direction C. At this time, the first push rod 32 and the second push rod 33 move backward away from the insertion plate portion 8321, causing the second locking protrusion 302 to disengage from the second locking hole 8322, and simultaneously the first locking protrusion 301 to disengage from the first locking hole 8311. In other words, at this time, the first electrical connector 100 and the mating connector 200 are unlocked on both sides. By applying other forces or by applying an upward component force to the first pull strap 7, the first electrical connector 100 can be pulled out from the mating connector 200.

[0132] The insert plate portion 8321 is housed in the large-diameter portion of the groove. During the locking and unlocking process, when the first movable component 3 moves the second locking protrusion 302 to cooperate with the second locking hole 8322, the insert plate portion 8321 abuts against the first baffle 303 and separates from the second baffle 304. When the first movable component 3 moves the second locking protrusion 302 to disengage from the second locking hole 8322, the insert plate portion 8321 abuts against the second baffle 304 and separates from the first baffle 303.

[0133] Please combine Figure 18 as well as Figure 19 As shown, the second electrical connector 100' includes a second insulating body 1', a plurality of second conductive terminals 2' fixed on the second insulating body 1', a second movable part 3' mounted on the second insulating body 1', a second elastic member (not shown) for abutting against the second movable part 3', a second cable 5' electrically connected to the second conductive terminals 2', a second cover plate 6' fastened to the second insulating body 1' and at least partially abutting against the second cable 5', and a second pull strap 7' connected to the second movable part 3'.

[0134] The second insulating body 1' includes a second main body portion 11', a second tongue plate 12' protruding downward along the mating direction B, and a second positioning plate 13' further protruding downward along the mating direction B from the second tongue plate 12'. The second conductive terminal 2' includes a second mating portion 21' disposed on the inner and outer surfaces of the second tongue plate 12'. In the embodiment illustrated in the present invention, the dimensions of the second main body portion 11' in the front-back direction / second direction, the dimensions of the second tongue plate 12' in the front-back direction, and the dimensions of the second positioning plate 13' in the front-back direction decrease sequentially, thereby making the second insulating body 1' substantially stepped. In the embodiment illustrated in the present invention, please refer to... Figure 18 and Figure 19 As shown, the second positioning plate 13' includes a fourth positioning piece 131' located in the middle, a fifth positioning piece 132' located on one side of the fourth positioning piece 131' and spaced apart from it, and a sixth positioning piece 133' located on the other side of the fourth positioning piece 131' and spaced apart from it. The dimension of the fourth positioning piece 131' in the left-right direction / first direction is larger than the dimension of the fifth positioning piece 132' in the left-right direction, and the dimension of the fourth positioning piece 131' in the left-right direction is also larger than the dimension of the sixth positioning piece 133' in the left-right direction. In the embodiment illustrated in the present invention, the distance between the fourth positioning piece 131' and the fifth positioning piece 132' is different from the distance between the fourth positioning piece 131' and the sixth positioning piece 133'. This arrangement can play a certain role in preventing mistaken insertion, ensuring that the second electrical connector 100' can be inserted into the other mating connector 200' at a certain angle.

[0135] Those skilled in the art will understand that the second electrical connector 100' in the electrical connector assembly of the first embodiment of the present invention is substantially the same as the first electrical connector 100, wherein the same or corresponding structures can be referred to the description of the first electrical connector 100, and will not be repeated hereafter.

[0136] Please combine Figure 6 and Figure 18As shown, those skilled in the art will understand that when the mating connector 200 is mounted on the first circuit board 300 in a first position and mates with the first electrical connector 100, and when the other mating connector 200' is mounted on the second circuit board 300 in a second position and mates with the second electrical connector 10', the outgoing direction of the first cable 5 of the first electrical connector 100 is the same as the outgoing direction of the second cable 5' of the second electrical connector 100', for example, both extending along the moving direction C. This arrangement allows the first cable 5 and the second cable 5' to be arranged together, avoiding cable folding, reducing the mating height, and thus helping to reduce the overall height of the electrical connector assembly.

[0137] Please combine Figures 20 to 41 As shown, a second embodiment of the present invention discloses an electrical connector assembly, comprising a first electrical connector 100, a mating connector 200 opposite to the first electrical connector 100, a second electrical connector 100', and another mating connector 200' opposite to the second electrical connector 100'. In the illustrated embodiment of the present invention, the first electrical connector 100 and the second electrical connector 100' are cable connectors, the mating connector 200 is a board-end connector for mounting to a first circuit board 300 in a first position, and the other mating connector 200' is a board-end connector for mounting to a second circuit board 300' in a second position. The first electrical connector 100 is used to mate with the mating connector 200 along the mating direction B (e.g., from top to bottom) to achieve data transmission. Please refer to... Figure 39 As shown, the second electrical connector 100' is used to mate with the other mating connector 200' along the mating direction B (e.g., from top to bottom) to enable data transmission.

[0138] In the embodiment illustrated in the present invention, the mating connector 200 and the other mating connector 200' are connectors with the same structure, except that their installation angles differ by 180°. In other words, it can be understood that the other mating connector 200' is formed by rotating the mating connector 200 by 180° in the plane where the circuit board is located.

[0139] The first circuit board 300 and the second circuit board 300' can be the same or different circuit boards. When the first circuit board 300 and the second circuit board 300' are the same circuit board, they are the same circuit board.

[0157] In the second embodiment illustrated in the present invention, the first insertion guide 8331a, the second insertion guide 8332a, the third insertion guide 8341a, and the fourth insertion guide 8342a are all inclined surfaces or arc surfaces. When the first electrical connector 100 is inserted into the mating connector 200, the first insertion guide 8331a, the second insertion guide 8332a, the third insertion guide 8341a, and the fourth insertion guide 8342a are configured to abut against the first partition wall 1414, the second partition wall 1424, the third partition wall 1514, and the fourth partition wall 1524, respectively, so that the first locking protrusion 8331, the second locking protrusion 8332, the third locking protrusion 8341, and the fourth locking protrusion 8342 can smoothly pass over the first partition wall 1414, the second partition wall 1424, the third partition wall 1514, and the fourth partition wall 1524, respectively, and be locked in the first retaining groove 1413, the second retaining groove 1423, the third retaining groove 1513, and the fourth retaining groove 1523, respectively. In the second embodiment illustrated in the present invention, the first retaining groove 1413, the second retaining groove 1423, the third retaining groove 1513, and the fourth retaining groove 1523 are respectively adapted to the first locking protrusion 8331, the second locking protrusion 8332, the third locking protrusion 8341, and the fourth locking protrusion 8342, so as to reduce the shaking that occurs when the first locking protrusion 8331, the second locking protrusion 8332, the third locking protrusion 8341, and the fourth locking protrusion 8342 are respectively locked in the first retaining groove 1413, the second retaining groove 1423, the third retaining groove 1513, and the fourth retaining groove 1523, thereby improving the docking stability.

[0158] Similarly, in the second embodiment illustrated in the present invention, the first pull-out guide portion 8331b, the second pull-out guide portion 8332b, the third pull-out guide portion 8341b, and the fourth pull-out guide portion 8342b are all inclined surfaces or arc surfaces. When the first electrical connector 100 is pulled out of the mating connector 200, the first pull-out guide 8331b, the second pull-out guide 8332b, the third pull-out guide 8341b, and the fourth pull-out guide 8342b are configured to abut against the first partition wall 1414, the second partition wall 1424, the third partition wall 1514, and the fourth partition wall 1524, respectively, so that the first locking protrusion 8331, the second locking protrusion 8332, the third locking protrusion 8341, and the fourth locking protrusion 8342 can smoothly pass over the first partition wall 1414, the second partition wall 1424, the third partition wall 1514, and the fourth partition wall 1524, respectively, and enter the first recessed groove 1412, the second recessed groove 1422, the third recessed groove 1512, and the fourth recessed groove 1522, respectively, to achieve unlocking on both the left and right sides.

[0159] Furthermore, when the first electrical connector 100 is inserted into the mating connector 200, the first positioning plate 13 is inserted into the positioning groove 8110, the first tongue plate 12 is inserted into the mating slot 8120, and the mating portion 21 of the first conductive terminal 2 contacts the elastic mating arm 821 of the mating terminal 82. During the process of the first electrical connector 100 being inserted into the mating connector 200, the inclined surfaces of the first locking protrusion 301 and the second locking protrusion 302 abut against the first sidewall 831 and the second sidewall 832, respectively. The first movable component 3 overcomes the force of the first elastic member 4 and moves inward a certain distance along the moving direction C. When the first locking protrusion 301 and the second locking protrusion 302 move downward to correspond to the first locking hole 8311 and the second locking hole 8322, the first elastic member 4 returns to its original position, causing the first movable component 3 to return to its original position in the opposite direction to the moving direction C. At this time, the first locking protrusion 301 and the second locking protrusion 302 both protrude forward into the first locking hole 8311 and the second locking hole 8322, so as to realize the locking of the first electrical connector 100 and the mating connector 200 on the front and rear sides.

[0160] Meanwhile, during the process of the first electrical connector 100 being inserted into the mating connector 200, the first extension protrusion 141 is inserted into the first receiving groove 851 under the guidance of the first guide slope 1411, the second extension protrusion 142 is inserted into the second receiving groove 852 under the guidance of the second guide slope 1421, the third extension protrusion 151 is inserted into the third receiving groove 861 under the guidance of the third guide slope 1511, and the fourth extension protrusion 152 is inserted into the fourth receiving groove 862 under the guidance of the fourth guide slope 1521. The first locking protrusion 8331 enters the first recessed groove 1412 and, guided by the first inclined surface 1414a, crosses the first recessed groove 1412 to be engaged in the first holding groove 1413; the second locking protrusion 8332 enters the second recessed groove 1422 and, guided by the second inclined surface 1424a, crosses the second recessed groove 1422 to be engaged in the second holding groove 1423; the third locking protrusion 8341 enters the third recessed groove 1512 and, guided by the third inclined surface 1514a, crosses the third recessed groove 1512 to be engaged in the third holding groove 1513; the fourth locking protrusion 8342 enters the fourth recessed groove 1522 and, guided by the fourth inclined surface 1524a, crosses the fourth recessed groove 1522 to be engaged in the fourth holding groove 1523. Ultimately, the first electrical connector 100 and the mating connector 200 achieve a locking mechanism on the left and right sides.

[0161] Those skilled in the art will understand that when the first electrical connector 100 is inserted into the mating connector 200 and fully engaged, the first protrusion 814 and the second protrusion 815 of the mating connector 200 are respectively engaged in the first slot 143 and the second slot 153 of the first electrical connector 100. By utilizing the height of the first protrusion 814 and the second protrusion 815 in the mating direction B, the first protrusion 814 and the second protrusion 815 can prevent the first electrical connector 100 from tilting due to external forces, thereby improving mating reliability. Those skilled in the art will understand that in the second embodiment illustrated in the present invention, the first protrusion 814 and the second protrusion 815 are integrally formed with the first connecting wall portion 8123 and the second connecting wall portion 8124, respectively. Of course, in other embodiments, the first protrusion 814 and the second protrusion 815 can also be separately disposed from the mating insulating body 81 and fixed to the mating insulating body 81 and / or the metal shell 83; this will not be elaborated further in this invention.

[0162] By providing the first locking protrusion 301 and the second locking protrusion 302 located on both sides, this invention achieves dual-sided locking in the front-back direction / second direction, thereby improving docking reliability and reducing the risk of loosening or tilting between the first electrical connector 100 and the docking connector 200. Furthermore, by having the first locking protrusion 8331, the second locking protrusion 8332, the third locking protrusion 8341, and the fourth locking protrusion 8342 respectively lock into the first retaining groove 1413, the second retaining groove 1423, the third retaining groove 1513, and the fourth retaining groove 1523, dual-sided locking in the left-right direction / first direction can be achieved, further improving docking reliability and further reducing the risk of loosening or tilting between the first electrical connector 100 and the docking connector 200.

[0163] When unlocking is required, an external force is applied to pull the first pull strap 7, which generates a component force along the moving direction C. This component force overcomes the force of the first elastic member 4, causing the first movable part 3 to move along the moving direction C. At this time, the first push rod 32 and the second push rod 33 move backward away from the insert plate portion 8321, causing the second locking protrusion 302 to disengage from the second locking hole 8322, while the first locking protrusion 301 also disengages from the first locking hole 8311.

[0164] Furthermore, during the unlocking process, the first latching protrusion 8331, the second latching protrusion 8332, the third latching protrusion 8341, and the fourth latching protrusion 8342, guided by the first pull-out guide portion 8331b, the second pull-out guide portion 8332b, the third pull-out guide portion 8341b, and the fourth pull-out guide portion 8342b, respectively, pass over the first partition wall 1414, the second partition wall 1424, the third partition wall 1514, and the fourth partition wall 1524 to achieve unlocking.

[0165] In other words, at this time, the first electrical connector 100 and the mating connector 200 have completed the unlocking on both sides in the left rear direction / first direction and the front and rear direction / second direction. By applying other forces or by applying an upward component force on the first pull strap 7, the first electrical connector 100 can be pulled out from the mating connector 200.
