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

[0075] Please refer to Figures 1 to 4 As shown, a first embodiment of the present invention discloses an electrical connector assembly, comprising an electrical connector 100 and a mating connector 200 corresponding to the electrical connector 100. In the illustrated embodiment, the electrical connector 100 is a pull tab connector and a cable connector, and the mating connector 200 is a board-end connector for mounting on a circuit board (not shown). Please refer to... Figure 3 As shown, the 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 and / or power transmission.

[0076] Please refer to Figures 7 to 24 As shown, the electrical connector 100 includes an insulating body 1, a plurality of conductive terminals 2 directly or indirectly disposed on the insulating body 1, a movable part 3 mounted on the insulating body 1, an elastic element 4 for abutting the movable part 3, a cable 5 electrically connected to the conductive terminals 2, a cover plate 6 fastened to the insulating body 1 and at least partially abutting the cable 5, and a pull strap 7 connected to the movable part 3. The pull strap 7 is configured to drive the movable part 3 to overcome the force of the elastic element 4, causing the movable part 3 to move in a direction C perpendicular to the mating direction B (see reference). Figure 3 (As shown).

[0077] In the illustrated embodiment of the present invention, the insulating body 1 includes a main body 11, an extension plate 12 protruding downward from the main body 11 along the mating direction B, and a positioning plate 13 further protruding downward from the extension plate 12 along the mating direction B. In the illustrated embodiment of the present invention, the dimensions of the main body 11 along the front-back direction / second direction, the dimensions of the extension plate 12 along the front-back direction, and the dimensions of the positioning plate 13 along the front-back direction decrease sequentially, thereby making the insulating body 1 substantially stepped.

[0079] Furthermore, the main body 11 also includes a top surface 116, an opening 1160 extending upward through the top surface 116, a first mounting hole 1161 extending upward through the top surface 116 and located on one side of the opening 1160, a second mounting hole 1162 extending upward through the top surface 116 and located on the other side of the opening 1160, a first mounting groove 1163 extending through the main body 11 and communicating with the opening 1160, and a second mounting groove 1164 extending through the main body 11 and communicating with the opening 1160. In the embodiment illustrated in the present invention, the first mounting groove 1163 and the second mounting groove 1164 are respectively located on both sides (e.g., the front and rear sides) of the extension plate 12. The 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 pull strap 7 extends from its connection with the movable member 3 along the moving direction C through the pull strap groove 1170, and extends out of the main body 11 after bending around the pull strap shaft 1171. The fixing plate 117 also 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 movable member 3, that is, the receiving holes 1172 are exposed on the surface of the fixing plate 117 facing the movable member 3. One end of the elastic member 4 is disposed in the receiving hole 1172, and the other end of the elastic member 4 abuts against the movable member 3.

In the illustrated embodiment of the present invention, the first conductive terminals 23 are embedded in the first insulating block 171. Of course, those skilled in the art will understand that in other embodiments, the first conductive terminals 23 may also be assembled and fixed to the first insulating block 171.

[0081] In the embodiment illustrated in the present invention, the first conductive mounting block 181 is made of a metal material to provide better shielding. The first conductive terminal 23 is not in contact with the first conductive mounting block 181 via the first insulating block 171, thereby preventing short circuits. The first conductive mounting block 181 includes a first base 1810 and a first protrusion 1811 extending from the first base 1810. The first base 1810 is provided with a plurality of first recessed grooves 1810a arranged at intervals in the left-right direction, and a first ridge 1810b and a second ridge 1810c respectively located on both sides of each first recessed groove 1810a. The first recessed groove 1810a is a U-shaped groove. The first ridge 1810b is provided with a first outer surface 1810d (e.g., a first upper surface), and the second ridge 1810c is provided with a second outer surface 1810e (e.g., a second upper surface).

The first rib 1811b is provided with a first surface 1811d, and the second rib 1811c is provided with a second surface 1811e. The first rib 1811b and the second rib 1811c serve as grounding terminals to mate with the mating connector 200. In addition, to improve the grounding shielding effect, the first surface 1811d of the first rib 1811b and the second surface 1811e of the second rib 1811c can both be provided with a plating layer. The plating layer is a gold plating layer or a plating layer of other metals to form good conductivity with the mating end.

[0083] The first insulating block 171 has a first end portion 1711 received in the first recessed groove 1810a and a first insertion portion 1712 extending from the first end portion 1711, the first insertion portion 1712 being inserted into the first assembly groove 1811a. In the embodiment illustrated in the present invention, the first end portion 1711 has an upper surface 1711a, which is flush with the first outer surface 1810d of the first protrusion 1810b and the second outer surface 1810e of the second protrusion 1810c when the first end portion 1711 is received in the first recessed groove 1810a and installed in place.

[0084] Preferably, to improve the transmission rate, in the embodiment illustrated in the present invention, there are two first conductive terminals 23 located on the same first insulating block 171, namely a first signal terminal S1 and a second signal terminal S2, wherein the first signal terminal S1 and the second signal terminal S2 form a differential pair. The first rib 1811b and the second rib 1811c are respectively located on both sides of the differential pair to improve the signal transmission quality. In the embodiment illustrated in the present invention, by providing a U-shaped first recessed groove 1810a, the first conductive mounting block 181 can surround the differential pair on three sides, thereby improving the signal transmission quality. In the embodiment illustrated in the present invention, each conductive terminal 2 is generally L-shaped, including a mating portion 21 and a connecting portion 22 electrically connected to the cable 5, wherein the connecting portion 22 is perpendicular to the mating portion 21. The mating portion 21 includes a mating surface 211, which is exposed on one surface of the first insertion portion 1712. The connecting portion 22 includes a welding surface 221, which is exposed at the first end portion 1711. In the embodiment illustrated in the present invention, the mating portion 21 is flat.

[0085] The first cable 51 includes a first core 511, a second core 512, a first insulating layer 513 wrapped around the first core 511, a second insulating layer 514 wrapped around the second core 512, a first grounding cable 515 located outside the first insulating layer 513, a second grounding cable 516 located outside the second insulating layer 514, and an outermost insulating sheath 517.

[0086] In the embodiment illustrated in the present invention, the first core 511 and the second core 512 are respectively welded and fixed to the welding surface 221 of the first signal terminal S1 and the welding surface 221 of the second signal terminal S2. The first grounding cable 515 and the second grounding cable 516 are respectively welded and fixed to the first outer surface 1810d of the first protrusion 1810b and the second outer surface 1810e of the second protrusion 1810c. Those skilled in the art will understand that by providing the first conductive mounting block 181, the welding of the first grounding cable 515 and the second grounding cable 516 is greatly facilitated. In other words, the first grounding cable 515 and the second grounding cable 516 are not limited to specific welding positions, as long as an electrical connection between the first grounding cable 515 and the second grounding cable 516 and the first conductive mounting block 181 can be achieved.

[0087] Please combine Figure 23 as well as Figure 24As shown in the illustrated embodiment of the present invention, the first conductive mounting block 181 has a first inclined surface 1813 exposed in the first assembly groove 1811a and a second inclined surface 1814 exposed in the first assembly groove 1811a. The first inclined surface 1813 and the second inclined surface 1814 form a V-shape, making the first assembly groove 1811a a dovetail groove that is narrower on the outside and wider on the inside. Correspondingly, the first insulating block 171 has a third inclined surface 1713 and a fourth inclined surface 1714 located on both sides respectively. The third inclined surface 1713 and the fourth inclined surface 1714 form a V-shape. When the first insulating block 171 is installed on the first conductive mounting block 181, the third inclined surface 1713 cooperates with the first inclined surface 1813, and the fourth inclined surface 1714 cooperates with the second inclined surface 1814, thereby preventing the first insulating block 171 from falling off the first conductive mounting block 181.

[0088] In the embodiment illustrated in the present invention, the first surface 1811d of the first rib 1811b and the second surface 1811e of the second rib 1811c are flush with the mating surface 211 of the first conductive terminal 23.

Each second terminal module 20 includes a second insulating block 172 and a plurality of second conductive terminals 24 disposed on the second insulating block 172. The second terminal module M2 has the same structure as the first terminal module M1, and will not be described in detail here.

[0090] Please combine Figures 25 to 31As shown, in a second embodiment of the electrical connector 100 of the present invention, in order to prevent the first insulating block 171 of the first terminal module M1 from falling off the first conductive mounting block 181, the first conductive mounting block 181 is provided with a first limiting block 1815 and a second limiting block 1816 located outside the first assembly groove 1811a, and the first insulating block 171 is provided with a first extending protrusion 1715 located at its bottom end. When the first insulating block 171 is installed on the first conductive mounting block 181, the first extending protrusion 1715 is inserted into the inner side of the first limiting block 1815 and is laterally blocked outward by the first limiting block 1815. At the same time, the first insulating block 171 is also laterally blocked outward by the second limiting block 1816. With this configuration, the first insulating block 171 can also be prevented from falling off the first conductive mounting block 181. In the second embodiment of the electrical connector 100 of the present invention, the first assembly groove 1811a does not penetrate downward through the end face 1812 of the first protrusion 1811.

[0091] In the embodiment illustrated in the present invention, during assembly, the first conductive mounting block 181, the first terminal module 10, and the first cable 51 are firstly combined into an integral first terminal module M1; similarly, the second conductive mounting block 182, the second terminal module 20, and the second cable 52 are combined into an integral second terminal module M2; then, the first terminal module M1 and the second terminal module M2 are respectively inserted into the first mounting groove 1163 and the second mounting groove 1164, with the first conductive mounting block 181 and the second conductive mounting block 182 at least partially extending out of the first mounting groove 1163 and the second mounting groove 1164, respectively located on the front and rear sides of the extension plate 12.

[0092] In the embodiment illustrated in the present invention, the extension plate 12, the first conductive mounting block 181, the first insulating block 171, the second conductive mounting block 182, and the second insulating block 172 together form a tongue plate 1a for insertion into the mating connector 200, and the mating portion 21 of the first conductive terminal 23 and the mating portion 21 of the second conductive terminal 24 are respectively exposed on two opposing surfaces of the tongue plate 1a.

[0093] In the embodiment illustrated in the present invention, the cable 5 extends beyond the main body 11 along the moving direction C.

[0094] Please refer to Figures 9 to 11As shown, the movable component 3 is at least partially installed in the main body 11. Specifically, the 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.

[0095] 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 main body 11. Of course, in other embodiments, the first locking protrusion 301 can also be manufactured separately from the 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 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 pull strap 7 is connected to the pull strap connecting portion 312. The movable component 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 is similar to 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 pull strap 7 passes through the through groove 311 and is sleeved around the pull strap connection portion 312.

[0096] In the embodiment illustrated in the present invention, the elastic element 4 is a compression spring installed between the base 31 and the inner wall surface 115 of the main body 11. Two compression springs are arranged side-by-side to improve the smoothness of movement of the movable part 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 10 (As shown).

[0097] The movable component 3 also includes a second locking protrusion 302 that protrudes rearward from the second end wall 112. In the illustrated embodiment of 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 illustrated embodiment of 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).

[0098] 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.

[0099] 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.

[0100] 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 a slot. 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-back direction is smaller than the size of the lower large-diameter portion in the front-back 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 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.

[0101] The second latching protrusion 302 protrudes from below the first stop wall 303 toward the second stop wall 304 and is spaced apart from the second stop wall 304 by a certain distance. 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 protrusion direction. The forward protrusion direction is opposite to the direction of movement C.

[0102] The 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 movable part 3 from moving excessively along the moving direction C under the action of the 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 movable part 3 from excessively returning to its original position in the opposite direction to the moving direction C when the elastic member 4 releases its restoring force.

[0103] The cover plate 6 is received and fixed in the opening 1160 of the main body 11, and the pull strap 7 extends out of the cover plate 6. In one embodiment of the invention, the cover plate 6 presses down on the connection between the cable 5 and the conductive terminal 2 (e.g., the welded part of the two) to provide protection.

[0104] Please refer to Figures 3 to 6 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 5 As shown, the plurality of wall portions 812 include a first wall portion 8121, a second wall portion 8122 disposed opposite to the first wall portion 8121, a first connecting wall portion 8123 connecting one side of the first wall portion 8121 and one side of the second wall portion 8122, and a second connecting wall portion 8124 connecting the other side of the first wall portion 8121 and the other side of the second wall portion 8122. The bottom wall 811 is provided with a positioning groove 8110 for receiving the 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.

[0105] 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.

[0106] 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.

[0107] The plurality of wall portions 812 form a mating slot 8120 for receiving the tongue plate 1a. 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 circuit board 300. The resilient mating arm 821 extends into the mating slot 8120 and is used to contact the mating portion 21.

[0108] 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.

[0109] When the electrical connector 100 is inserted into the mating connector 200, the positioning plate 13 corresponds to the positioning groove 8110, the tongue plate 1a corresponds to the mating slot 8120, and the mating portion 21 of the conductive terminal 2 corresponds to the elastic mating arm 821 of the mating terminal 82. As the 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 movable part 3 overcomes the force of the 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 elastic member 4 returns to its original position, causing the movable part 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 electrical connector 100 and the mating connector 200.

[0110] 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 of the electrical connector 100 and the docking connector 200.

[0111] When unlocking is required, an external force is applied to pull the pull strap 7. The pull strap 7 generates a component force along the movement direction C. This component force overcomes the force of the elastic element 4, causing the 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 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 pull strap 7, the electrical connector 100 can be pulled out from the mating connector 200.

[0112] The insert plate portion 8321 is housed in the large-diameter portion of the groove portion. During the locking and unlocking process, when the movable component 3 drives the second locking protrusion 302 to move 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 movable component 3 drives the second locking protrusion 302 to move 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.
