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

[0050] 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.

[0051] 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 .

[0052] see Figure 2 to Figure 6 As 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 ...

Embodiment 2

[0072] 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 .

[0073] 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

[0078] see Figure 19 to Figure 25 As shown, the plug A of the third embodiment is the same as that of the first embodiment, and the difference of the socket B is that the socket guide part 44 is partially different, and the structure of the socket reinforcing member 60 is inconsistent.

[0079] The supporting shoulders 4421 of the socket guiding part 44 of the socket body 40 of the third embodiment are respectively formed with avoidance slopes 4429 on both longitudinal sides, so that the tops of the supporting shoulders 4421 are relatively sharp supporting tops, and the installation steps 4425 and the elastic escape portion 4424 do not need to communicate through the communication step 4426 , that is, the communication step 4426 is eliminated. The rest of the structure of the socket step portion 44 is consistent with that of the first embodiment.

[0080] The socket reinforcement 60 of the third embodiment includes the same main body portion 61 , the central guide portion 63...

Abstract

Provided is a board-to-board socket. The board-to-board socket comprises a socket body, a socket terminal and a socket reinforcer; the socket body comprises a bottom wall, socket side walls formed byprotruding upwards from the two longitudinal ends of the bottom wall, and socket guide parts formed at the two transverse ends of the socket body. The socket guide part comprises a plug guide part receiving cavity, a longitudinal peripheral wall positioned on the transverse outer side of the plug guide part receiving cavity, and a pair of transverse peripheral walls positioned on the two longitudinal sides of the plug guide part receiving cavity; the socket reinforcer comprises a main body part covering the surface of the longitudinal peripheral wall, a transverse peripheral wall covering partextending from the two longitudinal sides of the main body part in the transverse direction to cover the transverse peripheral wall, and an elastic arm part extending from the transverse peripheral wall covering part to the side, close to the plug guide part receiving cavity, of the transverse peripheral wall. The top of the elastic arm part is bent and extends towards the longitudinal outer sideto form a hanging part hung on the top surface of the transverse 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. Such a tiny connector puts forward higher requirements for the structural strength of the connector.
