Detailed implementation manners

[0021] The following detailed implementation manners will further illustrate the present invention in conjunction with the above-mentioned drawings.

[0022] Figure 1-9 The first embodiment of the electrical connector 100 of the present invention is disclosed. Figures 10-13 The second embodiment of the electrical connector 100A of the present invention is disclosed. The structures of the two are substantially the same, and the main difference lies in the gripping plate members 30, 30A. Refer Figure 1 , Figures 10-13 As shown, the electrical connector 100 / 100A of the present invention is mounted on the circuit board 900, which includes an insulating body 10 and a plurality of conductive terminals. In a specific embodiment, the conductive terminals include power terminals 20P and a plurality of signal terminals 20S. The power terminals are larger in size and are mainly used to transmit large currents. The signal terminals are generally in a needle-like structure and are used to implement functions such as detection or device management. Since some of the conductive terminals are larger in structure, the insertion and extraction force required for them is relatively large. Gripping plate members 30 / 30A and a locking plate member 40 are provided to stably mount the electrical connector on the circuit board 900. The main improvement point of the present invention is to optimize the structure of the gripping plate member and improve the assembly of the electrical connector on the circuit board.

[0023] Refer Figure 1-9As shown, it shows the first embodiment of the present invention. The electrical connector 100 includes an insulating body 10, a plurality of conductive terminals, and a catch plate member 30. The insulating body at least includes an installation portion 11. The installation portion 11 is provided with a bottom surface 111 facing the circuit board 900, a top surface 112 opposite to the bottom surface, and a vertical surface 113 connecting the bottom surface and the top surface. The installation portion 11 is provided with a lock plate hole 12. The lock plate hole 12 penetrates the bottom surface 111, the top surface 112, and the vertical surface 113 to form a vertical surface opening 114. The catch plate member 30 is made of a metal plate and includes a fixing portion 31, a catch plate portion 32, and a blocking portion 33. The fixing portion 31 is fixed to the installation portion 11. The catch plate portion 32 is used to be fixed to the circuit board 900. The blocking portion 33 is attached to the vertical surface 113 and blocks the vertical surface opening 114. The blocking portion 33 further has an extension portion 333 at its lower edge.

[0024] For a similar structure, refer Figures 10-13 As shown, the catch plate member 30A in the second embodiment includes a blocking portion 32 and a catch plate portion 33. The catch plate member 30A is provided with a fixing opening 361. The installation portion is provided with a protruding fixing block 18. The fixing opening 361 is fixedly installed on the fixing block 18 by hard interference, thereby forming a fixing relationship. The fixing opening 371 constitutes the fixing portion.

[0025] Combined with Figure 13 As shown, the blocking portion 33 blocks the vertical surface opening 114 of the lock plate hole 12. When the lock plate member 40 is inserted into the lock plate hole 12 from the top surface 112, due to the existence of the blocking portion 33, even if the lock plate member 40 has a tendency to tilt outward, it is blocked by the blocking portion 33 and guided and adjusted. In this way, the blocking portion 33 can prevent the lock plate member 40 from tilting during the process of being installed into the lock plate hole 12. The blocking portion 33 made of metal has a certain elasticity and will not cause damage to the direction of the lock plate member 40. The extension portion 333 is lengthened in the up and down direction, which is beneficial to restricting the lock plate member 40. In this embodiment, the lock plate member is a bolt structure.

[0026] Furthermore, refer Figure 1-9 As shown, the blocking portion 33 includes an inner surface 331 facing the lock plate hole 12 and an opposite outer surface. The inner bottom surface is provided with a recessed portion 332. The recessed portion 332 penetrates in the up and down direction. The bolt is generally cylindrical. The recessed portion 332 can match a part of the surface of the lock plate member, which can better position and guide the installation of the lock plate member.

[0027] In this embodiment, the vertical surface 113 of the mounting portion includes a first vertical surface 1131 and a second vertical surface 1132 that are orthogonal to each other, and the vertical surface opening 114 is provided in the first vertical surface 1131. In this embodiment, the electrical connector 100 is a bent-angle electrical connector. The insulating body 10 is provided with a forward docking portion 13, and its docking direction is parallel to the circuit board 900. The lock plate hole 12 penetrates through two opposite side surfaces 141 of the insulating body. The first vertical surface 1131 is located on the side surface 141, and the second vertical surface 1132 is the rear end surface 142 opposite to the docking portion 13.

[0028] In this embodiment, the mounting portion 11 is provided with a fixing slot 15 that penetrates through the second vertical surface 1132, and the fixing portion 31 is inserted and fixed in the fixing slot 15. It can be seen that the fixing slot 15 is recessed forward from the rear end surface 142, and it extends in the horizontal direction, while the lock plate hole 12 extends in the up and down direction, and the two are perpendicular to each other.

[0029] Furthermore, the grasping plate member 30 includes a base portion 34. The grasping plate portion 32 extends downward from the base portion 34. An ear piece 351 is stamped out on the base portion and an opening 352 is reserved. The ear piece 35 is bent forward to form the fixing portion 31. The grasping plate member 30 is assembled into the mounting portion 11 from the rear forward. Its ear piece 351 is inserted into the fixing slot 15, thereby fixing the grasping plate member 30 to the mounting portion 11. The blocking portion 33 is bent from a side edge of the base portion 34, and the blocking portion is vertically arranged. The vertical blocking portion is attached to the first vertical surface 1131, and the increased dimension is very small.

[0030] Furthermore, the second vertical surface 1132 of the mounting portion 11 is provided with a protruding bump 16, and the bump 16 passes through and is fixed in the opening 352. The grasping plate portion 32 is a double-forked foot structure. The second vertical surface 1132 of the mounting portion is provided with a protruding vertical rib 18, and the vertical rib 18 is clamped between the double-forked feet, thereby further fixing the grasping plate member 30. The mounting portion 12 has a downward limiting surface 115. The blocking portion 33 abuts against the insulating body forward and abuts against the limiting surface 115 upward. In this way, the grasping plate member 30 is resisted by the limiting surface 115 upward and restricted by the vertical rib 18 downward.

[0031] Refer Figures 11-13 As shown, the circuit board 900 is provided with a first board hole 901 and a second board hole 902. After the electrical connector is mounted on the circuit board 900, the welding feet of the terminals are inserted into the terminal holes, and the grasping plate portion 32 is inserted into the first board hole 901. Further, the lock plate member 40 is inserted into the lock plate hole 12, and the nut is rotated and fixed at the end of the lock plate member 40. The top cap of the lock plate member abuts against the top surface 112 of the mounting portion, thereby further locking the electrical connector to the circuit board.

[0032] In some other embodiments, the lock plate hole 12 may be disposed adjacent to the rear end face 142 of the insulating body. The vertical surface opening 114 is located at the rear end face 142. The first vertical surface is the rear end face, and the second vertical surface is the side face orthogonal to the rear end face.

[0033] In some other embodiments, the electrical connector may be of a vertical type, with its docking portion extending upward and its docking direction being perpendicular to the circuit board. It can be understood that in the above embodiments, the surface on which the insulating body is seated on the circuit board is the bottom surface, and the opposite is the top surface.

[0034] Those of ordinary skill in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
