Patent No. 202010176952.4 of the People's Republic of China is a board-to-board connector component product that has been applied for research and development. Through structural improvement, the product has been able to adapt to the current transmission capacity of more than 5A. To be precise, both the socket and the plug can meet the current transmission of 10A. , but as the current transmission between the PCB main board and the battery is larger, the existing requirement proposes that the transmission current reaches 15A, and the plug structure of the patent application No. 202010176952.4 can no longer meet the transmission of such a large current, and needs to be improved

Embodiment 1

[0060] see figure 2 , Figure 8 to Figure 12 As shown, it is a schematic diagram of Embodiment 1 of the board-to-board plug A of the present application.

[0061] The plug body 10 of the plug A includes a top wall 11 , a pair of plug side walls 12 extending downward from both longitudinal sides of the top wall 11 , plug guides 14 formed on the lateral ends of the plug body 10 , and The island portion receives the cavity 13 between the top wall 11 , the pair of plug side walls 12 and the plug guide portion 14 .

[0062] The plug terminals 20 are integrally formed on a pair of plug side walls 12 in two rows in the lateral direction, and the plug guide portion 14 includes a bottom surface 141 , a lateral outer side surface 142 , a pair of longitudinal outer side surfaces 143 , and a pair of longitudinal outer sides 143 facing the island. The part receives the inclined surface 144 of the cavity 13 . An insertion groove 145 is formed extending along the bottom surface 141 , the...

Embodiment 2

[0075] see figure 2 , Figures 13 to 15 As shown, it is a schematic diagram of Embodiment 2 of the board-to-board plug A of the present application.

[0076] Compared with the first embodiment, the difference between the second embodiment is that the joint of the extension base 331 covering the top 33 of the plug reinforcement 30 and the welding leg 332 is bent upward to form a bent portion 334 , and the bent portion 334 makes the The horizontal position of the welding leg 332 is higher than the horizontal position of the extending base 331 . Finally, the extension base 331 is completely wrapped in the top wall 11 , that is, the extension base 331 is not exposed to the outside world. The guiding slope 323 is bent inward and wrapped in the plug guiding portion 14 .

[0077] At the same time, the solder pins 332 of the plug reinforcement 30 of the first embodiment and the second embodiment are in the same direction as the plug terminal solder pins 24 of the plug terminal 20 ...

Embodiment 3

[0080] please continue Figures 16 to 20 As shown, it is a schematic diagram of Embodiment 3 of the board-to-board plug A of the present application.

[0081] The plug body and the plug terminals of the board-to-board plug A in the third embodiment are the same as those in the first and second embodiments, and will not be repeated here.

[0082] The main difference is that the plug reinforcement 30 of the third embodiment includes a cover bottom 32 covering the bottom surface 141 of the plug guide portion 14 , and is bent downward from the longitudinal ends and the lateral outer side of the cover bottom 32 and covers the bottom surface 141 of the cover bottom 32 . The peripheral wall 31 on the longitudinal outer side surface 143 and the lateral outer side surface 142 and the connecting portion 34 formed by bending upward from the transverse inner side of the cover bottom 32 are formed.

[0083] The cover bottom 32 extends and covers the bottom surface 141 along the longitudin...

Abstract

The invention discloses a plug reinforcer. Comprising a covering bottom, a transverse peripheral wall formed by upward bending from the transverse outer side of the covering bottom, a longitudinal peripheral wall formed by upward bending from the longitudinal outer side of the covering bottom, a connecting part formed by upward bending and extending from the transverse inner side of the covering bottom, and weld legs formed by extending from the two longitudinal sides of the connecting part, and the connecting part and the covering top part are not overlapped when being observed in the vertical direction. The invention further comprises a board-to-board plug and a board-to-board connector assembly.

Description

technical field [0001] The present application relates to the field of electrical connectors, and more particularly, to a plug reinforcement, a board-to-board plug and a board-to-board connector assembly. Background technique [0002] Board-to-board connector assemblies are widely used in consumer electronics, such as smartphones, tablets, wearable devices, and more. At present, smartphones and wearable devices have extremely high space requirements, and the size of components is also shrinking. The spacing has also reached a distance of 0.25mm. Such a tiny connector puts forward higher requirements for the structural strength of the connector. Compared with the traditional board-to-board connector assembly, the large-scale functional integration of existing smartphones has The current carrying capacity puts forward higher requirements. The Patent No. 202010176952.4 of the People's Republic of China is a board-to-board connector component product that has been applied for ...
