Description

Background Art

[0002] Please combine Figure 1 as well as Figure 2 As shown, the electrical connector assembly in the related art generally includes a first circuit board 300", a docking connector 200" mounted on the first circuit board 300", and a first electrical connector 100" plugged with the docking connector 200". The docking connector 200" is provided with a docking 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 match the positioning slot of the docking connector 200" at a fixed angle. Please combine Figure 1 As shown, when the docking connector 200" is plugged into the first electrical connector 100", the state is as follows Figure 1 The electrical connector assembly is shown on the left.

[0003] As installation requirements continue to increase, Figure 1 In some cases, the docking connector 200" on the left side needs to be rotated 180° before being installed on the second circuit board 300"'. In other words, the structure of the docking connector 200" itself does not change, but the installation angle is rotated 180°. Those skilled in the art can understand that at this time, correspondingly, Figure 1 The outlet direction of the first cable 5" of the first electrical connector 100" plugged with the right-side docking connector 200" is bound to be opposite to the outlet direction of the first cable 5" of the first electrical connector 100" plugged with the left-side docking connector 200". In order to arrange the first cables 5" of the two first electrical connectors 100" together as much as possible, as shown in FIG. Figure 1 As shown, the related art proposes to fold the first cable 5 ″ of the first electrical connector 100 ″ on the right side in reverse, 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 likely to damage the first cable 5 ″.

[0005] Therefore, it is necessary to improve the docking connector and the electrical connector assembly in the related art. Utility Model Content

[0115] The base portion 31 is provided with a first locking projection 301 that protrudes forward beyond the first end wall 111. In the illustrated embodiment of the present invention, there are two first locking projections 301, which are respectively located on both sides (such as the left side and the right side) of the base portion 31 to improve the docking holding force. In the illustrated embodiment of the present invention, the first locking projection 301 is integrally formed with the first main body portion 11. Of course, in other embodiments, the first locking projection 301 can also be separately manufactured from the first main body portion 11 and then assembled and fixed together. In this case, the first locking projection 301 can be made of a material different from that of the first main body portion 11, such as a wear-resistant material with better structural strength. The base portion 31 is further provided with a strap connection portion 312, and the first strap 7 is connected to the strap connection portion 312. The first movable member 3 includes a through groove 311 that penetrates the base portion 31 along the moving direction C. The strap connection portion 312 is located above the through groove 311. The strap connection portion 312 is similar to a shaft portion and is located between the through groove 311 and the edge (such as the upper edge) of the base portion 31. One end of the first strap 7 passes through the through groove 311 and is wound around the strap connection portion 312.

[0116] In the illustrated embodiment of the present invention, the first elastic member 4 is a compression spring installed between the base portion 31 and the inner wall surface 115 of the first main body portion 11. There are two compression springs arranged side by side left and right to improve the smoothness of the movement of the first movable member 3. Additionally, in order to better position the compression spring, the base portion 31 is further provided with positioning posts 313 (please refer to Figure 12 shown) that are at least partially inserted into the compression spring.

[0117] The first movable member 3 further includes a second locking projection 302 protruding rearward from the second end wall 112. In the illustrated embodiment of the present invention, there are two second locking projections 302. One of the second locking projections 302 is located at the rear end of the first ejector rod 32 away from the base 31, outside the first receiving groove 113, and protruding toward the first receiving groove 113. The other second locking projection 302 is located at the rear end of the second ejector rod 33 away from the base 31, outside the second receiving groove 114, and protruding toward the second receiving groove 114 to improve the docking holding force. In the illustrated embodiment of the present invention, the second locking projection 302 and the corresponding ejector rod are integrally formed to save costs. Of course, in other embodiments, the second locking projection 302 can also be separately manufactured from the corresponding ejector rod and then assembled and fixed together. In this case, the second locking projection 302 can be made of a material different from that of the ejector rod. The first locking projection 301 and the second locking projection 302 are used to lock with the locking holes of the docking connector 200 to improve the docking holding force (to be described in detail later).

[0118] Please refer to Figure 10 、 Figure 11 and Figure 14 As shown, the first ejector rod 32 includes a first limiting groove 320 located in the middle, a first limiting surface 321 at one end of the first limiting groove 320 along the moving direction C, and a second limiting surface 322 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 ejector rod 33 includes a second limiting groove 330 located in the middle, a third limiting surface 331 at one end of the second limiting groove 330 along the moving direction C, and a fourth limiting surface 332 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 the end (rear end), and the second push rod 33 further includes a second groove 334 located at the end (rear end). Both the first groove 324 and the second groove 334 can be referred to as groove portions. Each of the groove portions has a first blocking wall 303 (e.g., a rear blocking wall), a second blocking wall 304 (e.g., a front lower blocking wall) disposed face to face with the first blocking wall 303 below, and a third blocking wall 305 (e.g., a front upper blocking wall) disposed face to face with the first blocking wall 303 above. A large diameter portion (not numbered) is formed between the first blocking wall 303 and the second blocking wall 304 below, and a small diameter portion (not numbered) is formed between the first blocking wall 303 and the third blocking wall 305 above. As the name implies, the size of the small diameter portion located above in the front-to-back direction is smaller than the size of the large diameter portion below in the front-to-back direction. It should be emphasized that: in the present embodiment, the groove portion is a groove portion that penetrates from top to bottom and includes an upper small-diameter portion and a lower large-diameter portion, and the small-diameter portion exists in response to the manufacturing process of the groove portion; in other embodiments, the groove portion may not be provided with an upper small-diameter portion and may only include a lower large-diameter portion, so that when the plug-in plate portion 8321 is accommodated in the groove portion that only includes the lower large-diameter portion, the groove portion moves in the front-to-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 plug-in plate portion 8321 for cooperation.

[0121] The second locking protrusion 302 protrudes from the bottom of the first blocking wall 303 toward the second blocking wall 304 and is separated from the second blocking wall 304 by a distance. Therefore, the first locking protrusion 301 also protrudes from the back to the front, so that the first locking protrusion 301 and the second locking protrusion 302 in the present invention have the same forward protrusion direction. Figure 6 , Figure 9 and Figure 10 It can be seen that the forward protruding direction is opposite to the moving direction 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 greater 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 greater than the dimension of the second pin 162 along the moving direction C. The first limiting surface 321 is used to abut against the first pin 161, and the third limiting surface 331 is used to abut against the second pin 162 to prevent the first movable member 3 from moving excessively along the moving direction C under the action of the first pulling belt 7; the second limiting surface 322 is used to abut against the first pin 161, and the fourth limiting surface 332 is used to abut against the second pin 162 to prevent the first movable member 3 from excessively returning in the direction opposite to the moving direction C when the first elastic member 4 releases the restoring force.

[0123] The first cover plate 6 is received and fixed in the opening 1160 of the first main body portion 11, and the first pulling belt 7 extends out of the first cover plate 6. In an embodiment of the present utility model, the first cover plate 6 presses against the connection part (such as the welding part) of the first cable 5 and the first conductive terminal 2 to play a protective role.

[0124] Please refer to Figures 4 to 10 and Figure 15 As shown, the docking connector 200 is provided with a docking insulating body 81, a plurality of docking terminals 82 fixed on the docking insulating body 81, and a metal housing 83 coated on the docking insulating body 81. The docking 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 illustrated embodiment of the present utility model, the first positioning groove 8111, the second positioning groove 8112, and the third positioning groove 8113 penetrate through the bottom wall 811.

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

[0126] In some embodiments, there are two terminal fixing blocks 84. The two terminal fixing blocks 84 are symmetrically arranged and spaced apart from each other. The plurality of docking terminals 82 are configured into two symmetric rows, and the two rows of docking terminals 82 are respectively fixed on the two terminal fixing blocks 84; there are two terminal accommodating grooves 813. The two terminal accommodating grooves 813 are symmetrically arranged and spaced apart from each other. The two terminal accommodating grooves 813 are respectively formed between the bottom wall 811 and two opposite wall portions 812. The two terminal fixing blocks 84 are fixed in the two terminal accommodating grooves 813. In some embodiments, each terminal fixing block 84 includes a plurality of first engaging portions 841, and one side of each terminal accommodating groove 813 includes a plurality of second engaging portions 8131 corresponding to the plurality of first engaging portions 841 respectively. Each first engaging portion 841 and the corresponding second engaging portion 8131 are engaged with each other to fix each terminal fixing block 84 in the corresponding terminal accommodating groove 813. In some embodiments, the plurality of first engaging portions 841 are respectively arranged on one side of the two terminal fixing blocks 84 facing each other, and the plurality of second engaging portions 8131 are respectively arranged on two opposite sides of the bottom wall 811 facing the two terminal accommodating grooves 813.

[0127] Please refer to Figure 10 and Figure 15 As shown, the plurality of wall portions 812 enclose a docking slot 8120 for accommodating the first tongue plate 12. The docking terminals 82 are arranged in two rows. The docking terminals 82 include elastic docking arms 821 and mounting tails 822 for mounting on the first circuit board 300. The elastic docking arms 821 extend into the docking slot 8120 and are used to contact the docking portion 21.

[0128] The metal housing 83 includes a first side wall 831, a second side wall 832 disposed opposite to the first side wall 831, a first connecting wall 833 connecting one side of the first side wall 831 and one side of the second side wall 832, and a second connecting wall 834 connecting the other side of the first side wall 831 and the other side of the second side wall 832. The first side wall 831 is provided with a first locking hole 8311 that cooperates with the first locking protrusion 301. At the corners of the second side wall 832 near the first connecting wall 833 and near the second connecting wall 834, i.e., on the left and right sides of the second side wall 832, there is provided an insertion plate portion 8321 each, and the insertion plate portion 8321 is provided with a second locking hole 8322 that cooperates with the second locking protrusion 302. In the illustrated embodiment of the present invention, the insertion plate portion 8321 is integrally formed on the second side wall 832, and there is also an integral formation between the insertion plate portion 8321 and the first connecting wall 833 and between the insertion plate portion 8321 and the second connecting wall 834 without any gap. Therefore, the insertion plate portion 8321 does not have elasticity.

[0129] When the first electrical connector 100 is inserted into the docking connector 200, the first positioning plate 13 corresponds to the positioning groove 8110, the first tongue plate 12 corresponds to the docking slot 8120, and the docking portion 21 of the first conductive terminal 2 corresponds to the elastic docking arm 821 of the docking 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 are respectively abutted against the first side wall 831 and the second side wall 832; the first movable member 3 overcomes the acting force of the first elastic member 4 and contracts inward by 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 restores its elastic force to cause the first movable member 3 to return in a direction opposite 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 docking connector 200.

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

[0131] When unlocking is required, an external force is applied to pull the first pulling belt 7. The first pulling belt 7 generates a component force along the moving direction C. The component force in this direction overcomes the acting force of the first elastic member 4, causing the first movable member 3 to move along the moving direction C. At this time, the first ejector rod 32 and the second ejector rod 33 move backward away from the insertion plate portion 8321, causing the second locking projection 302 to disengage from the second locking hole 8322 while the first locking projection 301 also disengages from the first locking hole 8311. In other words, at this time, the two sides of the first electrical connector 100 and the docking connector 200 are unlocked. By applying other acting forces or by applying an upward component force on the first pulling belt 7, the first electrical connector 100 can be pulled out of the docking connector 200.

[0132] The insertion plate portion 8321 is received in the large-diameter portion of the groove portion. During the locking and unlocking process, when the first movable member 3 drives the second locking projection 302 to move to cooperate with the second locking hole 8322, the insertion plate portion 8321 abuts against the first stop wall 303 and separates from the second stop wall 304. When the first movable member 3 drives the second locking projection 302 to move away from the second locking hole 8322, the insertion plate portion 8321 abuts against the second stop wall 304 and separates from the first stop wall 303.

[0133] Please refer to Figure 18 and 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 member 3' installed on the second insulating body 1', a second elastic member (not shown) for abutting against the second movable member 3', a second cable 5' electrically connected to the second conductive terminals 2', a second cover plate 6' buckled on the second insulating body 1' and at least partially abutting against the second cable 5', and a second pulling belt 7' connected to the second movable member 3'.

[0134] The second insulating body 1' includes a second main body portion 11', a second tongue plate 12' protruding downward from the second main body portion 11' along the docking direction B, and a second positioning plate 13' protruding downward from the second tongue plate 12' further along the docking direction B. The second conductive terminal 2' includes second docking portions 21' provided on the inner and outer surfaces of the second tongue plate 12'. In the illustrated embodiment of the present utility model, the dimension of the second main body portion 11' in the front-rear direction / second direction, the dimension of the second tongue plate 12' in the front-rear direction, and the dimension of the second positioning plate 13' in the front-rear direction decrease in sequence, so that the second insulating body 1' is substantially in a stepped shape. In the illustrated embodiment of the present utility model, 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 from the fourth positioning piece 131', and a sixth positioning piece 133' located on the other side of the fourth positioning piece 131' and spaced from the fourth positioning piece 131'. The dimension of the fourth positioning piece 131' in the left-right direction / first direction is greater 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 greater than the dimension of the sixth positioning piece 133' in the left-right direction. In the illustrated embodiment of the present utility model, 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'. With such a setting, a certain anti-misconnection function can be achieved, so that the second electrical connector 100' can be inserted into the other docking connector 200' at a determined angle.

[0135] Those skilled in the art to which the present utility model pertains can understand that the second electrical connector 100' in the electrical connector assembly of the first embodiment of the present utility model is substantially the same as the first electrical connector 100. For the same or corresponding structures, reference can be made to the description of the first electrical connector 100, and the present utility model will not be elaborated herein.

With such an arrangement, the first wire 5 and the second wire 5' can be arranged together, avoiding wire folding back, reducing the docking height, and being beneficial to reducing the overall height of the electrical connector assembly.

The first electrical connector 100 is used to dock with the docking connector 200 along the docking direction B (for example, the direction from top to bottom) to achieve data transmission. Please refer to Figure 39 As shown, the second electrical connector 100' is used to dock with the other docking connector 200' along the docking direction B (for example, the direction from top to bottom) to achieve data transmission.

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

[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.

[0159] In addition, when the first electrical connector 100 is inserted into the docking connector 200, the first positioning plate 13 is correspondingly inserted into the positioning groove 8110, the first tongue plate 12 is correspondingly inserted into the docking slot 8120, and the docking portion 21 of the first conductive terminal 2 contacts the elastic docking arm 821 of the docking terminal 82; during the process of inserting the first electrical connector 100 into the docking connector 200, the inclined surfaces of the first locking projection 301 and the second locking projection 302 respectively abut against the first side wall 831 and the second side wall 832; the first movable member 3 overcomes the acting force of the first elastic member 4 and moves inward a certain distance along the moving direction C; when the first locking projection 301 and the second locking projection 302 move downward to correspond to the first locking hole 8311 and the second locking hole 8322, the first elastic member 4 restores its elastic force to make the first movable member 3 return to its original position in the direction opposite to the moving direction C. At this time, the first locking projection 301 and the second locking projection 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 docking connector 200 on the front and rear sides.

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

[0161] Those skilled in the art can understand that when the first electrical connector 100 is inserted into the docking connector 200 and is inserted in place, the first protrusion 814 and the second protrusion 815 of the docking connector 200 are respectively clamped in the first slot 143 and the second slot 153 of the first electrical connector 100. By virtue of the heights of the first protrusion 814 and the second protrusion 815 in the docking 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 the docking reliability. Those skilled in the art can 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 provided from the docking insulating body 81 and fixed to the docking insulating body 81 and / or the metal housing 83, and the present invention will not elaborate on this.

[0162] By providing the first locking protrusions 301 and the second locking protrusions 302 on both sides, the present utility model 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. Additionally, by respectively locking the first locking bumps 8331, the second locking bumps 8332, the third locking bumps 8341, and the fourth locking bumps 8342 in the first clamping grooves 1413, the second clamping grooves 1423, the third clamping grooves 1513, and the fourth clamping grooves 1523, double-sided locking in the left-right direction / first direction can be achieved, further improving the 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 strap 7. The first strap 7 generates a component force along the moving direction C, and the component force in this direction overcomes the acting force of the first elastic member 4, causing the first movable member 3 to move along the moving direction C. At this time, the first ejector rod 32 and the second ejector rod 33 move backward away from the plug 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] Additionally, during the unlocking process, the first locking bumps 8331, the second locking bumps 8332, the third locking bumps 8341, and the fourth locking bumps 8342 respectively cross over the first partition wall 1414, the second partition wall 1424, the third partition wall 1514, and the fourth partition wall 1524 under the guidance of the first extraction guiding portion 8331b, the second extraction guiding portion 8332b, the third extraction guiding portion 8341b, and the fourth extraction guiding portion 8342b to achieve unlocking.

[0165] In other words, at this time, the first electrical connector 100 and the docking connector 200 complete unlocking on both sides in the left-back direction / first direction and both sides in the front-back direction / second direction. By applying other acting forces or an upward component force applied to the first strap 7, the first electrical connector 100 can be pulled out from the docking connector 200.
