Description

Technical field:

[0002] The utility model relates to the field of connector products, in particular to a socket for connecting keyboard keys. Background technology:

[0004] Connectors are primarily used in transportation, communications, networking, IT, healthcare, home appliances, aviation, and military electronics. Rapid technological advancements in these areas, along with rapid market growth, are driving the development of connector technology. To date, electrical connectors have evolved into a series of specialized products with a comprehensive range of product types, diverse specifications, diverse structural types, specialized product lines, distinct industry characteristics, and a standardized system of standards.

[0005] Generally speaking, connectors that cooperate with each other include sockets and plugs. Only when the sockets and plugs are coupled together can they achieve a circuit-breaking connection between them. For example, computer electronic equipment is widely used in various fields. Computer electronic equipment usually includes a keyboard device, which can quickly achieve input and output functions. Each key of a mechanical keyboard has an independent switch to control the closure. This switch is called a key switch. The key switch includes a keycap, an upper cover, a base, a moving contact piece, a static contact piece, a shaft and a reset spring. The keycap is connected to the top of the shaft, the upper cover is located above the base, and the shaft is located between the upper cover and the base. The upper and lower ends of the reset spring are respectively against the shaft and the base. The moving contact piece and the static contact piece are located on the side of the shaft. The feet of the moving contact piece and the static contact piece are welded through the holes in the circuit board, and then a connecting socket is used to realize the switch conduction.

[0006] The existing socket for connecting the keyboard includes a terminal and an insulating seat. The terminal is welded under the circuit board. After the keyboard switch is inserted into the circuit board, the pins of the keyboard switch are plugged into the socket of the keyboard to realize circuit conduction.

[0007] The keyboard key switch connection socket disclosed in Chinese announcement number CN205509070U has certain disadvantages. When the connection terminals are soldered on the circuit board and installed in the insulating seat of the connector, they need to be aligned and positioned first, and then the terminals are snapped into the grooves of the insulating seat. The terminals are deformed due to repeated contact with the keyboard pins, which shortens the service life of the keyboard socket. At the same time, due to the asymmetric structure of the connection socket, customers need to identify the direction correctly during assembly and patching, which causes trouble. Alternatively, they need to control the direction by designing anti-mistake fixtures, which makes the operation extremely inconvenient and has low assembly efficiency.

[0008] In view of this, the inventors aim at the limitations of the prior art and propose an improved socket for connecting keyboard keys to overcome the above-mentioned technical problems. Utility model content:
