Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to a power terminal and a plug connector. Background Art

[0002] As an indispensable part of electronic products, BTB connectors (also known as board-to-board connectors) have fast and stable transmission functions and the characteristics of low loss and high fidelity, and play a bridge of communication in electronic circuits. The multifunctional modules and high-speed development of smart phones and wearable devices have promoted the development of BTB connectors. Displays, touch screens, antenna connections, battery connections, microphone connections, cameras and other modules all need to be connected using BTB connectors. Therefore, in smart devices, there are relatively high requirements for the miniaturization, stability and reliability of BTB connectors.

[0003] The small BTB connectors currently on the market include male and female connectors for plug-in mating. During the plug-in mating process, the power terminals at both ends are subjected to greater force and wear. By covering the mating surface area of ​​the power terminal with a protective steel sheet, the plastic body can be protected and the connection strength can be increased. However, a weak point is formed in the transition connection area between the adjacent mating surfaces of the power terminal, which affects the plug-in strength. After long-term use, the plastic body in the transition connection area is prone to damage and destruction. The protective steel sheet in the mating surface area is a single-piece structure, which is prone to deformation and warping, which affects the stability of the plug-in mating, resulting in poor overall reliability and stability of the BTB connector.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0040] The present utility model embodiment provides a power terminal 23 and a plug connector including the power terminal 23, such as Figure 1 and Figure 2 As shown, the plug connector includes a male connector 1 and a female connector 2, which are plugged into each other. The female connector 2 includes a plastic body 21, a signal terminal 22 and a power terminal 23. The male connector 1 includes a male power terminal 11, which is plugged into the power terminal 23 of the female connector 2. Figure 3 and Figure 4Taking the female socket 2 as an example, all signal terminals 22, power terminals 23 and the plastic body 21 are injection molded into an integrated structure by insert molding. Among them, the signal terminals 22 and the power terminals 23 are both metal parts, and the power terminals 23 are arranged at both ends of the plastic body 21, which play a role in strengthening and protecting the two ends of the plastic body 21.

[0041] In order to achieve all-round protection for both ends of the plastic body 21, the power terminal 23 provided by the utility model is arranged at both ends of the plastic body 21. The power terminal 23 is an integrated structural member. The two sides and the outer end of the power terminal 23 are respectively provided with an outer protective sheet 231 and an outer end protective sheet 232. The outer protective sheet 231 extends toward one side of the outer end protective sheet 232 to provide a corner protective sheet 233, and the corner protective sheet 233 covers the corner area of ​​the plastic body 21.

[0042] like Figure 7-Figure 9 As shown, the corner protection sheet 233 is arranged at the corner between the side and end face of the power terminal 23 along one side edge of the outer protection sheet 231. The corner protection sheet 233 is a rounded transition structure and has a certain extension at the end to achieve comprehensive protection of the corner. When the male plug 1 and the female socket 2 are plugged in, it is beneficial to improve the plug-in matching strength and feel, facilitate operation, and can reduce the wear of the corner of the power terminal 23 on the male plug 1, increase the support strength of the corner of the power terminal 23 on the female socket 2, thereby achieving protection of the corner area of ​​the plastic body 21, and helping to reduce the damage and destruction of the power terminal 23 during long-term use, extending the service life of the power terminal 23 of the male plug 1 and the female socket 2, thereby improving the overall reliability and use stability of the power terminal 23.

[0043] In some embodiments, there is a gap between the corner protection sheet 233 and the outer end protection sheet 232. Figure 7 and Fig. 9 The width of the outer end protection sheet 232 is smaller than the end width of the power terminal 23. When the corner protection sheet 233 extends to one side of the end, there is still a gap between the corner protection sheet 233 and the outer end protection sheet 232. On the one hand, the gap is beneficial to the molding process of the corner protection sheet 233, and on the other hand, it is beneficial to the folding molding of the outer end protection sheet 232, and can cooperate with the plastic body 21 for positioning injection molding.

[0044] In some embodiments, the corner protection sheet 233 is formed on one side of the outer protection sheet 231 by drawing, which helps to ensure the consistency between the outer protection sheet 231 and the corner protection sheet 233 and save material costs.

[0045] In some embodiments, the bottom ends of the outer protective sheet 231 and the outer end protective sheet 232 of the power terminals 23 at both ends of the female socket 2 are folded outward to form a solder foot 234, and the root of the solder foot 234 is filled with a filler 235 to prevent solder creep.

[0046] like Figure 5 and Figure 6 As shown, the bottom ends of the outer protective sheet 231 and the outer end protective sheet 232 are folded toward the side away from the plastic body 21 to form a solder foot 234. In order to solve the solder creeping problem of the solder foot 234, a filler 235 is filled at the root of the soldering. The filler 235 can be a sealing material with the function of preventing solder creeping. In this embodiment, the same sealing material as the plastic body 21 is used and formed in one step during the injection molding process. By filling the filler 235 at the root of the solder foot 234, the soldering strength of the solder foot 234 can also be enhanced.

[0047] In some embodiments, an inner groove 2341 is defined at the root of the solder foot 234 , and the filler 235 is filled in the inner groove 2341 and protrudes out of the notch of the inner groove 2341 .

[0048] like Figure 7-Figure 13 An inner groove 2341 is provided between the bottom end of the outer protective sheet 231 and the root of the welding foot 234. The inner groove 2341 is provided through the width direction of the welding foot 234. The inner groove 2341 preferably has a quarter arc inner concave surface. The filler 235 is filled in the inner groove 2341. Figure 5 and Figure 6 The height of the filler 235 after filling protrudes from the notch of the inner groove 2341, which is beneficial to the stability of the filler 235 and has a good effect of preventing solder from creeping.

[0049] In some embodiments, a through hole 2342 is defined at the bottom of the inner groove 2341 .

[0050] Specifically, Fig. 9 As shown in the example, a through hole 2342 is provided at the bottom of the inner groove 2341 at the bottom of the outer protective sheet 232 and the root of its welding foot 234. The through hole 2342 allows the plastic on both sides of the outer protective sheet 232 to be connected as one, thereby improving the structural strength, facilitating the sealing and fixing, and avoiding the problem of incomplete mold. The through hole 2342 is preferably a long slot along the length direction of the inner groove 2341. The number of through holes 2342 can be more than one, and the size of the through hole 2342 can be designed according to the quality of the sealing glue used to facilitate sealing. In some embodiments, a through hole 2342 can also be provided at the bottom of the inner groove 2341 at the folded connection between the outer protective sheet 231 and its welding foot 234 to increase the firmness of the filler 235.

[0051] In some embodiments, the ends of the power terminals 23 at both ends of the female socket 2 further include an inner end protective sheet 238 , and the bottom end of the inner end protective sheet 238 is arranged coplanar with the welding foot 234 .

[0052] like Figure 6 and Fig.11 As shown, the inner end protective sheet 238 and the outer end protective sheet 232 are arranged opposite to each other on the inner and outer sides of the plug hole of the power terminal 23. The inner end protective sheet 238 and the outer end protective sheet 232 have the same depth as the plug hole, that is, the bottom end of the inner end protective sheet 238 is located at the bottom of the plug hole and is arranged coplanar with multiple welding feet 234. The inner end protective sheet 238 has the function of supporting and strengthening the end structure of the power terminal 23, especially the supporting force of the end during the plugging process has a structural strengthening effect.

[0053] The utility model also provides a plug connector, including a male connector 1 and a female connector 2 for plugging and matching. The two ends of the female connector 2 are respectively provided with power terminals 23 provided by the utility model. The two power end terminals 23 match with the male power terminals 11 at the two ends of the male connector 1.

[0054] The plug connector of the present invention realizes all-round protection of the plastic body 21 by arranging the power terminals 23 provided by the present invention at both ends of the plastic body 21 of the female socket 2, especially the protection of the corner area of ​​the plastic body 21, which is beneficial to improve the overall strength and protection capability of the plastic body 21, and enhance the overall reliability and stability of use.

[0055] In some embodiments, the power terminals 23 at both ends of the female socket 2 and the male power terminals 11 at both ends of the male connector 1 are snap-fitted to facilitate smooth plugging and unplugging.

[0056] Specifically, one of the male power terminal 11 on the male connector 1 and the corresponding power terminal 23 on the female connector 2 is provided with a latching protrusion 237, and the other is provided with a latching groove 236 that cooperates with the latching protrusion 237, and there is an installation gap between the correspondingly connected mating surfaces on both sides.

[0057] like Figure 8 As shown, the power terminal 23 on the female socket 2 is provided with a slot 236 on the inner wall of the outer protective sheet 231, which is formed by the inner concave and outer convex of the inner wall of the outer protective sheet 231. Fig.14 The outer wall of the male power terminal 11 of the male connector 1 is provided with a latching protrusion 237, which cooperates with the latching groove 236 to achieve latching, thereby locking the plugging position of the male connector 1 and the female connector 2. Preferably, the latching protrusion 237 and the latching groove 236 are symmetrically arranged on the two outer protective sheets 231 of each power terminal 23 to provide balanced force. When the latching protrusion 237 and the latching groove 236 are engaged, since both sides of the outer protective sheet 231 and the male power terminal 11 are elastic metal sheets, such as Fig.14There is an installation gap between the two outer protective sheets 231 and the two side surfaces of the male power terminal 11, so as to protect the plug connector from collision in the Z direction.

[0058] Similarly, if Figure 2 As shown, in the male plug 1 of the plug connector, the end face and corners of the male power terminal 11 are both metal sheets, which can provide protection against collisions in the X direction and at the corners; the bottom surface of the male power terminal 11 (i.e., the side facing the female socket 2) is a metal sheet, which is used to provide protection against collisions in the Y direction.

[0059] It should be noted that the folded positions of the outer protective sheet 231, the outer end protective sheet 232 and the inner end protective sheet are all connected to the top surface with rounded corners, and no edges or corners are generated. It can be understood that the plug connector provided by the utility model, through the two outer protective sheets 231, the outer end protective sheet 232, the inner end protective sheet, the corner protective sheet 233 and the top surface of the power terminal 23, provides multi-faceted and multi-corner protection for the end of the plastic body 21 of the female socket 2, which is beneficial to enhancing the structural strength of the plug connector and improving the stability of use.

[0060] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
