After that, the connecting member 8 is sleeved outside the second locking portion 52, so that the second locking portion 52 is limited in the fixing hole 85, and the supporting body 7 is connected and fixed with the fixing member 5 through the connecting member 8. Then, the insulating body 1 fixed to the metal shell 4 and the terminals 2 is mounted on the circuit board B such that the mating member C is disposed above the supporting body 7. Finally, the fixing member 5 and the metal shell 4 are fixed by the cooperation of the first locking portion 51 and the second locking portion 52, so that the supporting body 7 and the electrical connector 1000 can be stably fixed on the circuit board B, the supporting body 7 can stably support the butting element C, and the contact portion 21 of the terminal 2 can stably butt with the butting element C.
In summary, the connector assembly a of the present invention has the following advantages:
(1) the electric connector 1000 is fixed above the circuit board B, the supporting body 7 is arranged above the circuit board B, the supporting body 7 is located below the docking element C and used for supporting the docking element C upwards, and the supporting body 7 is fixedly connected with the electric connector 1000 through the connecting piece 8. In this way, the supporting body 7 can be stably fixed above the circuit board B without providing a fixing portion below the supporting body 7 to interfere with the fixing hole 85 of the circuit board B. Therefore, the processing procedure of the circuit board B is saved, and the requirement of the universality of the connector assembly A is met. And the positioning of the supporting body 7 is more convenient, when the electric connector 1000 is shaken by external force, the supporting body 7 will not shift on the circuit board B, so that the supporting body 7 can stably support the butting component C, thereby ensuring that the butting component C can be stably butted with the contact portion 21 of the terminal 2.
(2) The first positioning portion 73 is closer to the fixing member 5 than the second positioning portion 74, the positioning groove 75 is disposed between the first positioning portion 73 and the second positioning portion 74, and the limiting portion 81 of the connecting member 8 is received in the positioning groove 75, so that the connecting member 8 can limit the supporting body 7 in the front-rear direction, and further prevent the supporting body 7 from being displaced in the front-rear direction, and the first positioning portion 73 extends into and is limited in the fixing hole 85, so that the first positioning portion 73 can be prevented from being displaced in the left-right direction, and further the supporting body 7 can be prevented from being displaced in the left-right direction.
(3) The fixing member 5 is held between the first and second restricting portions 732, 733 and 82, and the first and second connecting portions 82, 83 and 83 are held between the third and fourth restricting portions 742, 743, respectively, in the arrangement direction of the plurality of terminals 2. In this way, not only the movement of the first positioning portion 73 in the left-right direction can be limited by the fixing member 5, but also the movement of the first positioning portion 73 and the second positioning portion 74 in the left-right direction can be further limited by the first connecting portion 82 and the second connecting portion 83, so as to avoid the movement of the support main body 7 in the left-right direction, and thus avoid the situation that the support main body 7 drives the docking element C to move in the left-right direction, so that the docking element C cannot be stably docked with the contact portion 21.
(4) The arc portion 84 and the limiting portion 81 are disposed opposite to each other, the arc portion 84 is disposed around one side of the fixing member 5 away from the docking element C, in the front-back direction, the first positioning portion 73 is located between the fixing member 5 and the limiting portion 81, the first positioning portion 73 is recessed into the arc groove 731 corresponding to the fixing member 5, and the fixing member 5 extends into the arc groove 731. Thus, the arc portion 84 and the arc groove 731 not only can move the second locking portion 52 of the fixing element 5, but also can limit the fixing element 5 in the front-rear direction, and the first positioning portion 73 is located between the fixing element 5 and the limiting portion 81, so that the first positioning portion 73 can be limited in the front-rear direction, and further the support body 7 can be prevented from moving in the front-rear direction, thereby preventing the support body 7 from driving the docking element C to move in the front-rear direction, and further preventing the docking element C from being unable to be stably docked with the contact portion 21.
(5) The bending angle of the bending portion 24 is an acute angle, and the second fixing portion 23 extends from one end close to the bending portion 24 to one side close to the contact portion 21 in an inclined manner. In this way, when the abutting portion 25 abuts against the circuit board B, the displacement amount in the front-rear direction when the abutting portion 25 and the second fixing portion 23 are pressed again is made small, so that the abutting portion 25 can accurately abut against the circuit board B.
(6) The bending part 24 has the first bending beam 241 and the second bending beam 242, the first fixing part 22 respectively with the one end of the first bending beam 241 and the one end of the second bending beam 242 are connected, the second fixing part 23 respectively with the other end of the first bending beam 241 and the other end of the second bending beam 242 are connected, the bending hole 243 is arranged between the first bending beam 241 and the second bending beam 242. In this way, the double-beam structure provided in the bent portion 24 not only can increase the width of the terminal 2 at the bent portion 24 and further reduce the characteristic impedance of the terminal 2 at the bent portion 24, but also can avoid the positive force of the terminal 2 at the bent portion 24, so that the abutting force between the abutting portion 25 and the circuit board B is too large.
The above detailed description is only for the purpose of illustrating the preferred embodiments of the present invention, and not for the purpose of limiting the scope of the present invention, therefore, all technical changes that can be made by applying the present specification and the drawings are included in the scope of the present invention.
