Hereinafter, some embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the case of no conflict, the following embodiments and features in the embodiments can be combined with each other.

Referring to FIG. 1 to FIG. 17, the present disclosure discloses a connector assembly, which includes an electrical connector 100 and a mating connector 200 for matching with the electrical connector 100. In the illustrated embodiment of the present disclosure, the electrical connector 100 is a pull strap connector and a cable end connector. The mating connector 200 is a board-end connector and is configured to be mounted to a circuit board 300. Referring to FIG. 1, the electrical connector 100 is configured to mate with the mating connector 200 along a mating direction B (for example, a top-to-bottom direction) to realize data and/or power transmission.

Referring to FIG. 1, FIG. 2, and FIG. 10 to FIG. 17, the electrical connector 100 includes an insulating body 1, a plurality of conductive terminals 2 directly or indirectly fixed to the insulating body 1, a movable component 3 installed on the insulating body 1, an elastic component 4 abutting against the movable component 3, a cable 5 electrically connected to the conductive terminal 2, a cover plate 6 that is fastened on the insulating body 1 and at least partially abuts against the cable 5, and a pull strap 7 connected to the movable component 3. The pull strap 7 is configured to drive the movable component 3 to overcome the force of the elastic component 4, so that the movable component 3 is able to move along a moving direction C (as shown in FIG. 1) perpendicular to the mating direction B.

Referring to FIG. 10 to FIG. 14, in the illustrated embodiment of the present disclosure, the insulating body 1 includes a main body 11, a extension plate 12 protruding downwardly from the main body 11 along the mating direction B, and a positioning plate 13 further protruding downwardly from the extension plate 12 along the mating direction B. In the illustrated embodiment of the present disclosure, a dimension of the main body 11 in a front-rear direction/a second direction, a dimension of the extension plate 12 in the front-rear direction, and a dimension of the positioning plate 13 in the front-rear direction become smaller in sequence, so that the insulating body 1 is roughly of a stepped configuration. Referring to FIG. 14, the positioning plate 13 includes a first positioning piece 131 located in a middle, a second positioning piece 132 located on one side of the first positioning piece 131, and a third positioning piece 133 located on another side of the first positioning piece 131. The second positioning piece 132 is spaced apart from the first positioning piece 131. The third positioning piece 133 is spaced apart from the first positioning piece 131. A dimension of the first positioning piece 131 along a left-right direction/a first direction is larger than a dimension of the second positioning piece 132 along the left-right direction. The dimension of the first positioning piece 131 along the left-right direction is also larger than a dimension of the third positioning piece 133 along the left-right direction. It is known that, the left-right direction is perpendicular to both the top-bottom direction and the front-rear direction. In the illustrated embodiment of the present disclosure, a distance between the first positioning piece 131 and the second positioning piece 132 is different from a distance between the first positioning piece 131 and the third positioning piece 133. This arrangement prevents the electrical connector 100 from being inserted into the mating connector 200 at a wrong angle, so that a certain foolproof effect can be achieved.

Referring to FIG. 13 and FIG. 14, the main body 11 includes a first end wall 111 (for example, a front end wall) and a second end wall 112 (for example, a rear end wall) opposite to the first end wall 111. The main body 11 further includes a receiving space 110 extending forwardly through the first end wall 111, a first receiving groove 113 located on one side (for example, a left side) of the receiving space 110, and a second receiving groove 114 located on another side (for example, a right side) of the receiving space 110. The receiving space 110 does not extend backwardly through the second end wall 112. The main body 11 includes an inner wall surface 115 exposed to the receiving space 110. The first receiving groove 113 and the second receiving groove 114 extend through the second end wall 112 along the moving direction C.

Besides, the main body 11 includes a top surface 116, an opening 1160 extending upwardly through the top surface 116, a first mounting hole 1161 extending upwardly through the top surface 116 and located on one side of the opening 1160, a second mounting hole 1162 extending upwardly through the top surface 116 and located on another side of the opening 1160, a first assembly groove 1163 extending through the main body 11 and communicating with the opening 1160, and a second assembly groove 1164 extending through the main body 11 and communicating with the opening 1160. In the illustrated embodiment of the present disclosure, the first assembly groove 1163 and the second assembly groove 1164 are located on two sides (for example, front and rear sides) of the extension plate 12, respectively. The main body 11 further includes a fixing plate 117 located between the first end wall 111 and the second end wall 112. In the illustrated embodiment of the present disclosure, the fixing plate 117 is a vertical plate. The fixing plate 117 includes a pull strap groove 1170 extending therethrough along the moving direction C, and a pull strap shaft 1171 located between an edge (for example, an upper edge) of the fixing plate 117 and the pull strap groove 1170. The pull strap 7 extends through the pull strap groove 1170 along the moving direction C from a connection with the movable component 3, and the pull strap is bent along the pull strap shaft 1171 and then extends out of the main body 11. The fixing plate 117 further includes at least one receiving hole 1172. In the illustrated embodiment of the present disclosure, the number of the receiving holes 1172 is two. The receiving holes 1172 are exposed on a surface of the fixing plate 117 and face towards the movable component 3. One end of the elastic component 4 is disposed in the receiving hole 1172 and another end of the elastic component 4 abuts against the movable component 3.

Referring to FIG. 10 to FIG. 14, in the illustrated embodiment of the present disclosure, the electrical connector 100 includes a first terminal module M1 and a second terminal module M2. The first terminal module M1 includes a first mounting block 181, a plurality of first conductive terminals 23 fixed to the first mounting block 181 and a plurality of first cables 51 connected to the first conductive terminals 23. The first mounting block 181 is made of insulating material and is provided with a first surface 121. In the illustrated embodiment of the present disclosure, the first conductive terminals 23 are insert-molded with the first mounting block 181. Of course, it is understandable to those skilled in the art that in other embodiments, the first conductive terminals 23 can also be fixed to the first mounting block 181 through assembly or other means. The first cables 51 and the first conductive terminals 23 are fixed by soldering or welding.

Similarly, the second terminal module M2 includes a second mounting block 182, a plurality of second conductive terminals 24 fixed to the second mounting block 182 and a plurality of second cables 52 connected to the second conductive terminals 24. The second mounting block 182 is made of insulating material and is provided with a second surface 122 which is opposite to the first surface 121. In the illustrated embodiment of the present disclosure, the second conductive terminals 24 are insert-molded with the second mounting block 182. Of course, it is understandable to those skilled in the art that in other embodiments, the second conductive terminals 24 can also be fixed to the second mounting block 182 through assembly or other means. The second cables 52 and the second conductive terminals 24 are fixed by soldering or welding.

To facilitate understanding of the present disclosure, the conductive terminals 2 include the first conductive terminals 23 and the second conductive terminals 24. The cables 5 include the first cables 51 and the second cables 52.

Each conductive terminal 2 includes a mating portion 21 and a connecting portion 22 electrically connected to the cable 5. In the illustrated embodiment of the present disclosure, the mating portions 21 of the conductive terminals 2 are flat-shaped, and exposed to the first surface 121 and the second surface 122, respectively.

In the illustrated embodiment of the present disclosure, during assembly, the first mounting block 181, the first conductive terminals 23 and the first cables 51 are firstly combined into the integrated first terminal module M1. Similarly, the second mounting block 182, the second conductive terminals 24 and the second cables 52 are combined into the integrated second terminal module M2. Then, the first terminal module M1 and the second terminal module M2 are inserted into the first assembly groove 1163 and the second assembly groove 1164, respectively. The first mounting block 181 and the second mounting block 182 at least partially pass through the first assembly groove 1163 and the second assembly groove 1164, respectively, so as to be located at the front and rear sides of the extension plate 12, respectively.

In the illustrated embodiment of the present disclosure, the extension plate 12, the first mounting block 181 and the second mounting block 182 together form a tongue plate 1a for being inserted into the mating connector 200. The mating portions 21 of the first conductive terminals 23 and the mating portions 21 of the second conductive terminals 24 are exposed on two opposite surfaces of the tongue plate 1a, respectively.

Of course, it is understandable to those skilled in the art that in other embodiments of the present disclosure, the first mounting block 181 and the second mounting block 182 can be integrally formed with the extension plate 12 to form an integral tongue plate 1a. At this time, in a first embodiment of the present disclosure, the conductive terminals 2 are insert-molded with the insulating body 1. Of course, in a second embodiment, the conductive terminals 2 can also be directly mounted to the insulating body 1; or in a third embodiment, the conductive terminals 2 and an insulating block are combined into a terminal module, and then the terminal module is mounted to the insulating body 1. The fixing method of the conductive terminals 2 and the insulating body 1 is well known to those of ordinary skill in the art, and will not be described in detail in the present disclosure.

Preferably, in order to increase the transmission rate, in the illustrated embodiment of the present disclosure, the conductive terminals 2 located on the tongue plate 1a include a plurality of high-speed signal terminal pairs. Each high-speed signal terminal pair includes a first signal terminal S1 and a second signal terminal S2. The first signal terminal S1 and the second signal terminal S2 form a differential pair. The conductive terminals 2 further includes a first ground terminal G1 and a second ground terminal G2 which are disposed on two sides of each differential pair, respectively. Adjacent differential pairs may share one ground terminal (for example, the first ground terminal G1 or the second ground terminal G2). With this arrangement, the conductive terminals 2 are arranged in a G1-S1-S2-G2 arrangement, so as to increase the transmission rate and improve the quality of signal transmission.

In the illustrated embodiment of the present disclosure, the cable 5 extends beyond the main body 11 along the moving direction C.

The movable component 3 is at least partially installed to the main body 11. The movable component 3 includes a base 31, a first ejector rod 32 extending backwardly from one side of the base 31, and a second ejector rod 33 extending backwardly from another side of the base 31. The base 31 is accommodated in the receiving space 110. Most of the first ejector rod 32 is accommodated in the first receiving groove 113 except a rear end of the first ejector rod 32 which extends out of the first receiving groove 113. Most of the second ejector rod 33 is accommodated in the second receiving groove 114 except a rear end of the second ejector rod 33 which extends out of the second receiving groove 114. Both the first ejector rod 32 and the second ejector rod 33 can be referred to as ejector rods which extend from the first end wall 111 to the second end wall 112 with the rear ends thereof protruding beyond the second end wall 112.

The base 31 includes two first locking protrusions 301 located on two sides (for example, left and right sides) of the base 31, respectively, so as to improve the mating retention force. The first locking protrusions 301 are integrally formed with the main body 11 and extend forwardly beyond the first end wall 111. Of course, in another embodiment, the first locking protrusions 301 and the main body 11 can also be manufactured separately, and then assembled and fixed together. In this case, the first locking protrusions 301 can be made of a material, for example, a wear-resistant material with better structural strength, different from that of the main body 11. The base 31 further includes a pull strap connecting portion 312 to which the pull strap 7 is connected. The movable component 3 includes a transverse slot 311 extending through the base 31 along the moving direction C. The pull strap connecting portion 312 is located above the transverse slot 311. The pull strap connecting portion 312 is similar to a shaft portion, and is located between the transverse slot 311 and the edge (for example, the upper edge) of the base 31. One end of the pull strap 7 passes through the transverse slot 311 and is sleeved around the pull strap connecting portion 312.

In an alternative embodiment of the present disclosure, the number of the first locking protrusion 301 can be only one and the first locking protrusion 301 protrudes forwardly from a middle part of the first end wall 111. The first locking protrusion 301 has same distances to both the left-front side of the base 31 and the right-front side of the base 31.

In the illustrated embodiment of the present disclosure, the elastic component 4 is a compression spring installed between the base 31 and the inner wall surface 115 of the main body 11. The number of the compression springs is two, and the two compression springs are arranged side by side to improve the stability of the moving element 3 when the moving element 3 is moving. Besides, referring to FIG. 14, in order to better positioning the compression spring, the base 31 is further provided with a positioning post 313 which is at least partially inserted into the compression spring.

The movable component 3 further includes at least one second locking protrusion 302 protruding backwardly beyond the second end wall 112. In the illustrated embodiment of the present disclosure, the number of the second locking protrusions 302 is two. One of the second locking protrusions 302 is located at the rear end of the first ejector rod 32 away from the base 31. The one of the second locking protrusions 302 is located outside the first receiving groove 113 and protrudes toward the first receiving groove 113. A remaining one of the second locking protrusions 302 is located at the rear end of the second ejector rod 33 away from the base 31. The remaining one of the second locking protrusions 302 is located outside the second receiving groove 114 and protrudes toward the second receiving groove 114. The two second locking protrusions 302 are arranged in such a manner to improve an engagement force. The second locking protrusion 302 is integrally formed with a corresponding ejector rod to save cost. Of course, in another embodiment, the second locking protrusion 302 and the corresponding ejector rod can also be produced separately, and then assembled and fixed together. In this case, the second locking protrusion 302 can be made of a different material from that of the corresponding ejector rod. The first locking protrusions 301 and the second locking protrusions 302 are to lock with locking holes of the mating connector 200 to improve the mating retention force.

The two first locking protrusions 301 and the two second locking protrusions 302 are both arranged on the left side and the right side of the electrical connector, so that the present disclosure can realize a double-side locking purpose, thereby improving the mating retention force between the electrical connector and the mating connector. In an alternative embodiment, the only one first locking protrusion 301 is arranged on the middle part of the electrical connector and the two second locking protrusions 302 are arranged on the left side and the right side of the electrical connector, which can also realize the double-side locking purpose, thereby improving the mating retention force between the electrical connector and the mating connector.

Referring to FIG. 10 and FIG. 11, the first ejector 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 is located at another end of the first limiting groove 320 along the moving direction C. Compared with the second limiting surface 322, the first limiting surface 321 is closer to the first end wall 111.

Similarly, the second ejector 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 is located at another end of the second limiting groove 330 along the moving direction C. Compared with the fourth limiting surface 332, the third limiting surface 331 is closer to the first end wall 111.

The first ejector rod 32 further includes a first concave groove 324 located at a distal end (for example, a rear end) thereof, and the second ejector rod 33 further includes a second concave groove 334 located at a distal end (for example, a rear end) thereof. Both the first concave groove 324 and the second concave groove 334 are referred to as groove portions. Each groove portion has a first blocking wall 303 (for example, a rear blocking wall), a second blocking wall 304 (for example, a front lower blocking wall) and a third blocking wall 305 (for example, a front upper blocking wall). The second blocking wall 304 is located below the first blocking wall 303 to face the first blocking wall 303. The third blocking wall 305 is located above the first blocking wall 303 to face the first blocking wall 303. A large-diameter portion (not numbered) is formed between the first blocking wall 303 and the second blocking wall 304, and a small-diameter portion (not numbered) is formed between the first blocking wall 303 and the third blocking wall 305. A dimension of the small-diameter portion in the front-rear direction is smaller than a dimension of the large-diameter portion in the front-rear direction.

It should be noted that: in this embodiment, the groove portion extends vertically, and includes the small-diameter portion and the large-diameter portion. The small-diameter portion exists according to the manufacturing process of the groove portion. In another embodiment, the groove portion does not include the small-diameter portion and only includes the large-diameter portion, so that when the insertion plate portion 8321 is accommodated in the groove portion which only includes the large-diameter portion, the groove portion can move together with the movable component 3 in the front-rear direction, and the second locking protrusion 302 can be inserted into the second locking hole 8322 of the insertion plate portion 8321 for engagement.

The second locking protrusion 302 protrudes from the bottom of the first blocking wall 303 toward the second blocking wall 304. The second locking protrusion 302 is spaced from the second blocking wall 304 by a distance. Because the first locking protrusion 301 also protrudes from the rear to the front, the first locking protrusion 301 and the second locking protrusion 302 in the present disclosure have the same forward protruding direction. The forward protruding direction is opposite to the moving direction C.

The electrical connector 100 includes a first pin 151 fixed in the first mounting hole 1161 and a second pin 152 fixed in the second mounting hole 1162. The first pin 151 is inserted into the first limiting groove 320 and the second pin 152 is inserted into the second limiting groove 330. A dimension of the first limiting groove 320 is larger than a dimension of the first pin 151 along the moving direction C. A dimension of the second limiting groove 330 is larger than a dimension of the second pin 152 along the moving direction C. The first limiting surface 321 is used for engaging with the first pin 151, and the third limiting surface 331 is used for engaging with the second pin 152, so as to prevent the movable component 3 from moving excessively along the moving direction C. The second limiting surface 322 is used for engaging with the first pin 151, and the fourth limiting surface 332 is used for engaging with the second pin 152, so as to prevent the movable component 3 from returning excessively along an opposite direction of the moving direction C.

The cover plate 6 is accommodated and fixed in the opening 1160 of the main body 11, and the pull strap 7 extends out of the cover plate 6. The cover plate 6 presses against the connection between the cables 5 and the conductive terminals 2 (for example, welding portions of the cables 5 and the conductive terminals 2), so as to play a protection role.

Referring to FIG. 1 to FIG. 9, 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 shell 83 enclosing 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. The bottom wall 811 defines a positioning groove 8110 for accommodating the positioning plate 13. Specifically, the positioning groove 8110 includes a first positioning groove 8111 for accommodating the first positioning piece 131, a second positioning groove 8112 for accommodating the second positioning piece 132, and a third positioning groove 8113 for accommodating the third positioning piece 133. The first positioning groove 8111, the second positioning groove 8112 and the third positioning groove 8113 all extend through the bottom wall 811.

The mating connector 200 includes a terminal fixing block 84 to which the mating terminals 82 are fixed. The mating insulating body 81 includes a terminal accommodating groove 813 in which the terminal fixing block 84 is fixed. The terminal fixing block 84 includes a first engaging portion 841. A second engaging portion 8131 is provided on one side of the terminal accommodating groove 813. The first engaging portion 841 and the second engaging portion 8131 are engaged with each other, so that the terminal fixing block 84 is fixed in the terminal accommodating groove 813. In the illustrated embodiment of the present disclosure, the first engaging portion 841 is a dovetail-shaped bump and the second engaging portion 8131 is a dovetail-shaped groove matching the dovetail-shaped bump.

In some embodiments, the number of the terminal fixing blocks 84 is two, and the two terminal fixing blocks 84 are symmetrical and spaced apart from each other. The mating terminals 82 are arranged in two symmetrical rows and the two rows of mating terminals 82 are fixed to the two terminal fixing blocks 84, respectively. Two terminal accommodating grooves 813 are provided, and the two terminal accommodating grooves 813 are symmetrical and spaced apart from each other. The two terminal accommodating grooves 813 are respectively formed between the bottom wall 811 and the two opposite wall portions 812. The two terminal fixing blocks 84 are fixed in the two terminal accommodating grooves 813. Each of the terminal fixing blocks 84 includes a plurality of first engaging portions 841. One side of each of the terminal accommodating grooves 813 includes a plurality of second engaging portions 8131 corresponding to the plurality of first engaging portions 841 respectively. Each of the first engaging portions 841 and the corresponding second engaging portions 8131 are engaged with each other, so that each terminal fixing block 84 is fixed in the corresponding terminal accommodating groove 813. The first engaging portions 841 are respectively disposed on the sides of the two terminal fixing blocks 84 facing each other. The second engaging portions 8131 are respectively disposed on opposite sides of the bottom wall 811 facing the two terminal accommodating grooves 813.

The wall portions 812 are enclosed to form a mating slot 8120 for receiving the tongue plate 1a. The mating terminals 82 are arranged in two rows. Each mating terminal 82 includes an elastic mating arm 821 and a mounting tail 822. The mounting tail 822 is used for being mounted on a circuit board 300. The elastic mating arm 821 extends into the mating slot 8120 for being in contact with the mating portion 21.

The metal shell 83 includes a first side wall 831, a second side wall 832, a first connecting wall 833, and a second connecting wall 834. The second side wall 832 is disposed opposite to the first side wall 831. The first connecting wall 833 connects one side of the first side wall 831 and one side of the second side wall 832. The second connecting wall 834 connects another side of the first side wall 831 and another side of the second side wall 832. The first side wall 831 defines a first locking hole 8311 engaged with the first locking protrusion 301. The second side wall 832 includes two insertion plate portion 8321 at a corner adjacent to the first connecting wall 833 and at a corner adjacent to the second connecting wall 834. That is to say, each of the left and right sides of the second side wall 832 includes one insertion plate portion 8321. The insertion plate portion 8321 defines a second locking hole 8322 matched with the second locking protrusion 302. The insertion plate portion 8321 is integrally formed on the second side wall 832. The insertion plate portion 8321 and the first connecting wall 833 are integrally formed, and the insertion plate portion 8321 and the second connecting wall 834 are also integrally formed without any gap. Therefore, the insertion plate portion 8321 has no elasticity.

When the electrical connector 100 is inserted into the mating connector 200, the positioning plate 13 is correspondingly accommodated in the positioning groove 8110, the extension plate 12 is correspondingly accommodated in the mating slot 8120, and the mating portions 21 of the conductive terminals 2 correspondingly contact the elastic mating arms 821 of the mating terminals 82. With the insertion of the electrical connector 100, the inclined surface of the first locking protrusion 301 abuts against the first side wall 831, and the inclined surface of the second locking protrusion 302 abuts against the second side wall 832. The movable component 3 overcomes the force of the elastic component 4, and shrinks inward by a certain distance along the moving direction C. When the first locking protrusion 301 moves downwardly to the first locking hole 8311, and the second locking protrusion 302 moves downwardly to the second locking hole 8322, the elastic force of the elastic component 4 is released, so that the movable component 3 moves backwardly in the direction opposite to the moving direction C. The first locking protrusion 301 protrudes forwardly into the first locking hole 8311, and the second locking protrusion 302 protrudes forwardly and protrudes into the second locking hole 8322, thereby realizing the locking of the electrical connector 100 and the mating connector 200.

In the present disclosure, by providing the first locking protrusion 301 and the second locking protrusion 302 on two sides, two-side locking in the front-rear direction/the second direction can be achieved, thereby improving the mating reliability, and reducing the risk of the electrical connector 100 and the mating connector 200 becoming loose or tilted.

When the electrical connector 100 and the mating connector 200 need to be unlocked, an external force is applied to pull the pull strap 7, and the pull strap 7 generates a component force along the moving direction C, and the component force in this direction overcomes the force of the elastic component 4, so that the movable component 3 moves along the moving direction C. The first ejector rod 32 and the second ejector rod 33 move away from the insertion plate portion 8321 backwards, so that the second locking protrusion 302 and the second locking hole 8322 are disengaged from each other. The first locking protrusion 301 and the first locking hole 8311 are also separated from each other. In other words, the electrical connector 100 and the mating connector 200 are unlocked on two sides. As a result, the electrical connector 100 can be pulled out of the mating connector 200 by applying another force or by an upward component force exerted on the pull strap 7.

The insertion plate portion 8321 is accommodated in the large-diameter portion of the groove portion in both the locked state of the electrical connector 100 and the mating connector 200, and the unlocked state of the electrical connector 100 and the mating connector 200. When the movable component 3 drives the second locking protrusion 302 to move, and the second locking protrusion 302 cooperates with the second locking hole 8322, the insertion plate portion 8321 is in contact with the first blocking wall 303, and the insertion plate portion 8321 is separated from the second blocking wall 304. When the movable component 3 drives the second locking protrusion 302 to move, and the second locking protrusion 302 and the second locking hole 8322 are disengaged from each other, the insertion plate portion 8321 is in contact with the second blocking wall 304, and the insertion plate portion 8321 is separated from the first blocking wall 303.

Besides, in order to further reduce the risk of oblique insertion, the insulating body 1 of the electrical connector 100 further includes a first extension portion 14 and a second extension portion 15 which protrude downwardly beyond the main body 11 along the mating direction B.
