Problems solved by technology

At present, smart phones and wearable devices have extremely high space requirements, and the size of components is also shrinking. The minimum height of the board-to-board plugs and sockets of first-line board-to-board manufacturers has reached an ultra-low height of 0.6mm. The spacing has also reached 0.25mm. Such a tiny connector puts forward higher requirements for the structural strength of the connector. Compared with traditional board-to-board connector components, the large-scale functional integration of existing smart phones is very important for The current carrying capacity puts forward higher requirements, such as LCD screens, etc., which require a current transmission capacity of 5A. The traditional board-to-board connector component design has been unable to meet the current market requirements for strength and current transmission.

Embodiment 1

[0043] see figure 1 As shown, the board-to-board connector assembly of the present application includes a plug A mounted on a printed circuit board and a socket B mounted on another printed circuit board, and the plug A and the socket B are interlocked and connected.

[0044] The plug A includes a plug body 10 , a plurality of plug terminals 20 formed in the plug body 10 , and plug reinforcements 30 fixed at both lateral ends of the plug body 10 . The socket B includes a socket body 40 , a socket terminal 50 installed on the socket body 40 , and socket reinforcing pieces 60 installed and fixed at both lateral ends of the socket body 40 .

[0045] see Figure 2 to Figure 6As shown, 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, and plug guides formed at both lateral ends of the plug body 10. 14 and an island receiving cavity 13 formed between the top wall 11 , a pair of p...

Embodiment 2

[0065] read on Figure 16 to Figure 18 As shown, it is the second embodiment of the board-to-board connector assembly of the present application. The board-to-board plug A of this embodiment is consistent with the first embodiment, and the only difference lies in the partial structure of the receptacle reinforcement 60 .

[0066] The difference between the second embodiment and the first embodiment is that the position of the covering portion 64 of the lateral peripheral wall corresponding to the hook portion 654 cancels the avoidance notch 643 in the first embodiment, but covers it from the lateral peripheral wall The portion 64 protrudes upwards corresponding to the hooking portion 654 to form a contact piece 644 , and the free end of the hooking portion 654 is punched into a smaller contact tip. When the plug A is inserted into the receptacle B, the elastic body arm 652 is deformed longitudinally outward to force the contact tip 655 of the hook portion 654 to extend toward ...

Embodiment 3

[0071] read on Figure 19 to Figure 22 As shown, this embodiment is one of the alternative solutions of Embodiment 2, and the difference compared with Embodiment 2 is:

[0072] The support shoulder 4421 is provided with a notch groove 4429 with a deeper recess depth at the position of the lower groove 4423 . The top of the lateral peripheral wall covering portion 64 does not need to protrude upwards to form the contact piece 644 , but instead, the longitudinal outer end of the hooking portion 654 extends outward and is at least partially located above the lateral peripheral wall covering portion 64 , and the hooking portion 654 further includes a lower contact portion 656 punched downward at a position corresponding to the notch 4429 , and an inclined contact surface 657 is formed on the bottom surface of the lower contact portion 656 . The lower contact portion 656 is formed by punching and tearing a part of the hook portion 654 downward, and tears the hook portion 654 from ...

Abstract

A board-to-board socket, including a socket body, socket terminals and socket reinforcements, the socket body includes a bottom wall, socket side walls protruding upward from both ends of the bottom wall in the longitudinal direction, and formed on the socket body laterally The socket guides at both ends protrude upward from the bottom wall to form an island, the socket guide includes a plug guide receiving cavity, a longitudinal peripheral wall located laterally outside the plug guide receiving cavity, and a wall located on the plug guide receiving cavity. A pair of transverse peripheral walls on both longitudinal sides of the receiving cavity, the socket reinforcement includes a main body covering the upper surface of the longitudinal peripheral wall, a transverse transverse extending from the main body and covering the lateral peripheral wall The outer peripheral wall covering part and the elastic arm part extending from the lateral peripheral wall covering part to the side of the lateral peripheral wall close to the receiving cavity of the plug guide part, the top of the elastic arm part is bent and extended toward the longitudinal outer side to form a hook The hooking portion on the top surface of the transverse outer peripheral wall.

Description

technical field [0001] The present application relates to the field of electrical connectors, in particular to a board-to-board socket. Background technique [0002] Board-to-board connector assemblies are widely used in consumer electronics, such as smartphones, tablets, wearable devices, etc. At present, smart phones and wearable devices have extremely high space requirements, and the size of components is also shrinking. The minimum height of the board-to-board plugs and sockets of first-line board-to-board manufacturers has reached an ultra-low height of 0.6mm. The spacing has also reached 0.25mm.
