The traditional line to board connector usually includes a male head shell and a female seat shell, and the male head terminal and the soldering terminal are correspondingly arranged inside. The insertion of the male head terminal and the soldering terminal realizes the connection of current and the transmission of signal.
[0003] However, with the increasing trend of miniaturization and integration of electronic devices, higher requirements are put forward for the volume and size of the connector. In particular, in some instrument-type electronic devices, due to the limited internal space, the traditional line to board connector with large volume is often difficult to assemble, thereby limiting its application in these fields.
[0004] Although there are various line to board connector products on the market at present, most of these products have large volume and cannot meet the size requirements of the connector for small electronic devices such as instruments. Specifically, the male head shell and the female seat shell of these connectors are relatively complex in design, and the buckle structure is often large, resulting in a large overall volume and making it difficult to assemble into electronic devices with limited space such as instruments.

[0007] Further, the connector further includes a waterproof structure arranged at the bottom of the male head shell, which includes a stepped protrusion and a waterproof ring sleeved outside the male head shell, and the waterproof ring is located at the upper part of the stepped protrusion.
[0008] Further, the male head shell and the female seat shell are connected and fixed through a buckle structure, and the buckle structure includes:
[0009] A clamping protrusion connected and fixed to the side of the male head shell;
[0010] The connecting fixed elastic deformation branch arm on the side of the female seat shell, the bottom end of the branch arm is connected with the hook, and the branch arm and the hook are integrated.
[0011] Further, the clamping protrusion and the branch arm are arranged on the same side, and a transition slope one is arranged on the top of the clamping protrusion.
[0012] Further, the bottom of the hook is provided with a transition slope two matched with the transition slope one, so that the hook is smoothly clamped into the clamping protrusion.
[0013] Further, the male head shell, the female seat shell, the male head terminal, the solder wire terminal, the waterproof ring, the clamping protrusion, the branch arm and the hook jointly constitute a wire-to-board connector which is compact in structure, easy to assemble and has dustproof and waterproof functions.
[0014] The utility model provides a wire-to-board connector. Compared with the prior art, the utility model has the following beneficial effects:
[0015] The wire-to-board connector successfully adapts to the assembly space of small electronic devices such as instruments by reducing the volume and size, solves the problem that the traditional wire-to-board connector cannot be applied to instruments due to the excessively large volume. In addition, the connector also meets market demand and is designed to have a style that satisfies SMT assembly, further improving its applicability and flexibility in electronic devices. This innovative design not only meets the special requirements of small electronic devices such as instruments for the size of the connector, but also provides strong technical support for the miniaturization and integration trend of electronic devices, and has important practical value and application prospect.
