Then, the positioning posts 522 of the fixing member 5 are inserted into the through holes 2' of the circuit board B, and the lower surface of the second locking portion 52 is welded to the upper surface of the circuit board B, so that the second locking portion 52 is fixed on the circuit board B. Then, the limiting portion 81 of the connecting member 8 is fixed in the positioning groove 75, so that the supporting body 7 is connected and fixed with the connecting member 8. After that, the connecting piece 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 piece 5 through the connecting piece 8. Then, the insulating body 1 fixed to the metal shell 4 and the terminals 2 is mounted on the circuit board B, so that the abutting element C is disposed above the supporting body 7. Finally, the fixing piece 5 is fixed to the metal housing 4 by 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 to the circuit board B, the supporting body 7 can stably support the docking element C, and the contact portion 21 of the terminal 2 can stably dock with the docking element C.
In summary, the connector assembly a of the present invention has the following advantages:
(1) The electrical connector 1000 is fixed above the circuit board B, the supporting body 7 is disposed above the circuit board B, and the supporting body 7 is disposed below the docking element C to support the docking element C upwards, and the supporting body 7 is fixedly connected with the electrical connector 1000 through the connecting piece 8. This makes it possible to stably fix the support body 7 above the circuit board B without providing a fixing portion below the support body 7 to interfere with the fixing hole 85 of the circuit board B. Thus, the processing procedure of the circuit board B is saved, and the requirement of the connector assembly A on universality is met. But also the positioning of the supporting body 7 can be facilitated, when the electric connector 1000 is shaken by an external force, the supporting body 7 does not deviate on the circuit board B, so that the supporting body 7 can stably support the abutting element C, thereby ensuring that the abutting element C can stably abut against 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 accommodated in the positioning groove 75, so that the connecting member 8 can limit the supporting body 7 in the front-rear direction, further prevent the supporting body 7 from displacing 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 moving in the left-right direction, and further the supporting body 7 can be prevented from moving in the left-right direction.
(3) In the arrangement direction of the plurality of terminals 2, the fixing member 5 is limited between the first limiting portion 732 and the second limiting portion 733, the first limiting portion 732 and the second limiting portion 733 are limited between the first connecting portion 82 and the second connecting portion 83, and the first connecting portion 82 and the second connecting portion 83 are limited between the third limiting portion 742 and the fourth limiting portion 743. In this way, not only the fixing member 5 may limit the movement of the first positioning portion 73 in the left-right direction, but also the first connecting portion 82 and the second connecting portion 83 may further limit the movement of the first positioning portion 73 and the second positioning portion 74 in the left-right direction, so as to avoid the movement of the supporting body 7 in the left-right direction, so that the situation that the supporting body 7 drives the abutting element C to move in the left-right direction, so that the abutting element C cannot be stably abutted with the contact portion 21 occurs.
(4) The arc portion 84 is disposed opposite to the limiting portion 81, and the arc portion 84 is disposed around one side of the fixing member 5 away from the abutting element C, along the front-rear direction, the first positioning portion 73 is located between the fixing member 5 and the limiting portion 81, and the first positioning portion 73 is disposed in a concave manner with respect to the fixing member 5, where the arc groove 731 is disposed, and the fixing member 5 extends into the arc groove 731. In this way, the arc-shaped portion 84 and the arc-shaped groove 731 not only can give way to the second locking portion 52 of the fixing member 5, but also can limit the fixing member 5 in the front-rear direction, and the first positioning portion 73 is located between the fixing member 5 and the limiting portion 81, so that the first positioning portion 73 can be limited in the front-rear direction, and further, the movement of the supporting body 7 in the front-rear direction can be prevented, so that the situation that the supporting body 7 drives the abutting element C to move in the front-rear direction, and the abutting element C cannot be stably abutted with the contact portion 21 is avoided.
(5) The bending angle of the bending portion 24 is an acute angle and the second fixing portion 23 extends obliquely from one end near the bending portion 24 toward the side near the contact portion 21. In this way, when the abutting portion 25 abuts against the circuit board B, the displacement amount of the second fixing portion 23 and the abutting portion 25 in the front-rear direction is small when being pressed again, so that the abutting portion 25 can accurately abut against the circuit board B.
(6) The bending portion 24 has the first bending beam 241 and the second bending beam 242, the first fixing portion 22 is connected to one end of the first bending beam 241 and one end of the second bending beam 242, the second fixing portion 23 is connected to the other end of the first bending beam 241 and the other end of the second bending beam 242, and the bending hole 243 is provided between the first bending beam 241 and the second bending beam 242. In this way, the bent portion 24 has a double beam structure, which not only increases the width of the terminal 2 at the bent portion 24 and thus reduces the characteristic impedance of the terminal 2 at the bent portion 24, but also prevents the contact portion 25 from having an excessive contact force with the circuit board B due to the forward force of the terminal 2 at the bent portion 24.
The above detailed description is merely illustrative of the preferred embodiments of the invention and is not intended to limit the scope of the invention, so that all equivalent technical changes that can be made by the present specification and illustrations are included in the scope of the invention.
