However, when the electronic device falls, the connection between the welding terminal and the circuit board is subjected to impact force, that is, the welding terminal is subjected to impact force, which may easily cause the position of the welding terminal to crack and disconnect the electrical connection, thereby causing the electronic components of the electronic device to fail to function. Summary of the invention

It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.
[0013] In the following, in conjunction with the accompanying drawings, the board-to-board connector and its socket, and the electronic device provided in the embodiments of the present application are described in detail through specific embodiments and their application scenarios.
[0014] Please refer to Figure 1-Figure 6 The socket of the board-to-board connector disclosed in the embodiment of the present application includes a socket body 100 and a welding terminal 200 arranged on the socket body 100, wherein the socket body 100 serves as the main component of the socket, and the socket body 100 is used to support the welding terminal 200; the welding terminal 200 is used to connect the welding area of the circuit board 30 to realize the electrical connection between the welding terminal 200 and the circuit board 30.
[0015] Optionally, the welding terminal 200 may be in a block shape, a sheet shape, etc. The embodiment of the present application does not limit the specific structure of the welding terminal 200. The welding terminal 200 is connected to the socket body 100 by assembly or integral molding. The welding terminal 200 is used for welding with the circuit board 30, and the welding terminal 200 is connected to the surface of the circuit board 30 by welding.
[0016] The socket body 100 is further provided with a supporting protrusion 300, and the welding terminal 200 and the supporting protrusion 300 are located on the same side of the socket body 100. Moreover, the surface of the welding terminal 200 facing away from the socket body 100 is the first surface 210, and the supporting protrusion 300 is provided protruding relative to the first surface 210. In this way, when the supporting protrusion 300 contacts the circuit board 30 for support, the welding terminal 200 is welded to the circuit board 30.
[0017] Optionally, the material of the support protrusion 300 may be but is not limited to plastic, the support protrusion 300 may be a block-shaped protrusion, a strip-shaped protrusion, etc., the block-shaped protrusion may be a square, circular or other structure, and the embodiment of the present application does not limit the specific structure of the support protrusion 300.
[0018] Specifically, when the support protrusion 300 is protruding relative to the first surface 210, when the electronic device falls, the force borne by the welding terminal 200 is transferred to the support protrusion 300, that is, the contact position between the support protrusion 300 and the circuit board 30 bears most of the impact force, thereby reducing the impact force borne by the welding terminal 200.
[0019] In the embodiment of the present application, a support protrusion 300 is additionally provided on the socket of the board-to-board connector. Since the support protrusion 300 is protruding relative to the first surface 210 of the welding terminal 200, when the electronic device falls, the contact position between the support protrusion 300 and the circuit board 30 will bear the impact force, sharing the impact force borne by the connection between the welding terminal 200 and the circuit board 30, which is beneficial to reduce the impact force borne by the welding terminal 200, avoid cracking of the welding terminal 200 and disconnection of the electrical connection, and further avoid functional failure of the electronic components of the electronic device.
[0020] In an optional embodiment, along the extension direction of the socket body 100 , the socket body 100 has a first end 100 a and a second end 100 b , and the first end 100 a or the second end 100 b of the socket body 100 is provided with a supporting protrusion 300 .
[0021] In another embodiment, reference Figure 5 As shown, the first end 100a and the second end 100b of the socket body 100 are both provided with a support protrusion 300, and the welding terminal 200 is located between the support protrusion 300 provided at the first end 100a and the support protrusion 300 provided at the second end 100b. Optionally, along the extension direction of the socket body 100, a plurality of welding terminals 200 are arranged at intervals, and the structures of each welding terminal 200 can be the same or different.
[0022] With this embodiment, the number of supporting protrusions 300 is increased, so at least two supporting protrusions 300 respectively share the impact force borne by the welding terminal 200, and the impact force borne by the welding terminal 200 is further reduced, which can more effectively avoid cracking at the welding terminal 200; moreover, at least two supporting protrusions 300 are respectively located on both sides of the welding terminal 200, which is conducive to the force of each supporting protrusion 300 being consistent, thereby ensuring the balance of the socket.
[0023] In an optional embodiment, the socket body 100 is an insulating body, the support protrusion 300 is an insulating protrusion, and the insulating body and the insulating protrusion are an integrated structure. Optionally, the socket body 100 and the support protrusion 300 are both made of plastic, and the socket body 100 and the support protrusion 300 can be formed into an integrated structure by injection molding. Of course, the socket body 100 and the support protrusion 300 can also be made of other insulating materials besides plastic.
[0024] In this embodiment, the socket body 100 and the support protrusion 300 are both insulating structures, and the two adopt an integrated structure. The support protrusion 300 is directly produced when the socket body 100 is produced, and there is no need to set the support protrusion 300 separately, which is conducive to simplifying the production and design process; moreover, there is no need to perform a connection operation between the socket body 100 and the support protrusion 300, and there is no connection gap between the two, so the connection stability between the two is stronger.
[0025] Of course, in other embodiments, the support protrusion 300 and the socket body 100 may be a split structure, and the support protrusion 300 may be separately disposed on the socket body 100 .
[0026] In the scheme of this application, reference is made to Figure 2 and Figure 4 As shown, the socket further includes a fixing sheet 400, which is disposed on the socket body 100. Optionally, the fixing sheet 400 and the socket body 100 can be a split structure, and the two are connected together by assembly or the like, or the fixing sheet 400 and the socket body 100 are injection molded into an integral structure. The fixing sheet 400 and the supporting protrusion 300 are located on the same side of the socket body 100, and the fixing sheet 400 is used to connect the circuit board 30. In this way, when the fixing sheet 400 faces the circuit board 30 and is connected to the circuit board 30, the supporting protrusion 300 contacts the circuit board 30, and the welding terminal 200 is further welded to the circuit board 30.
[0027] In this embodiment, the fixing sheet 400 is connected to the circuit board 30 to determine the relative position of the circuit board 30 and the socket, thereby achieving relative fixation between the two and avoiding position displacement of the socket relative to the circuit board 30. At the same time, the connection area between the socket and the circuit board 30 is increased, thereby improving the connection stability between the socket and the circuit board 30.
[0028] In a further embodiment, the fixing piece 400 is protruded relative to the surface of the supporting protrusion 300 facing away from the socket body 100, so that the protruding portion of the fixing piece 400 extends into the slot 301a of the circuit board 30.

In addition, the plug-in connection method can avoid floating and false welding problems, and avoid cracking at the connection between the welding terminal 200 and the circuit board 30.

[0032] Optionally, the fixing plate 400 also includes a fixing plate body 410, which is disposed on the socket body 100, and is connected to a welding plate 420, and the welding plate 420 is bent relative to the fixing plate body 410 so that the plane where the welding plate 420 is located is parallel to the first surface 210.

Then, the welding plate 420 occupies less space on the circuit board 30, which is beneficial to reducing the space occupied by the socket on the circuit board 30.

[0041] In this embodiment, the first end 100a and the second end 100b of the socket body 100 are connected to the circuit board 30 through the fixing piece 400, so the relative position of the first end 100a of the socket body 100 and the circuit board 30 is determined, and the relative position of the second end 100b of the socket body 100 and the circuit board 30 is determined, which is more conducive to fixing the position of the socket as a whole relative to the circuit board 30, and further avoiding the position displacement of the socket relative to the circuit board 30.
