[0007] Among them, the card slot includes a limiting transverse groove with an opening on the top, and the bottom of the limiting transverse groove is connected to a through groove. The welding needle includes a limiting part and a welding part connected to the bottom of the limiting part. The limiting part is correspondingly arranged in the limiting transverse groove, and the welding part passes through the through groove. The bottom of the welding part can be welded and connected to the circuit board.

[0008] Preferably, limit points are provided on both sides of the limit portion.

[0009] Preferably, both sides of the bottom of the welding portion are provided with upward inclined welding surfaces.

[0010] Preferably, an arc-shaped concave surface is arranged above the welding surface.

[0019] In order to make the technical problems solved by the utility model, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the utility model will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0020] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
