Network connector structure

Technical Field

The present application relates to a connector, and more particularly, to a network connector structure.

Background

In order to avoid interference from external electric waves in signal transmission, conventional network connectors such as RJ45 (Registered Jack 45) are protected by electronic components such as filters and their circuits. The filter in the early stage is mainly formed by soldering electronic components such as coils to a circuit board, which has the disadvantage that the filter is not easy to process, and occupies a large volume, so that the network connector cannot be miniaturized. The filter device composed of electronic devices such as integrated circuit can effectively reduce the occupied volume to achieve the purpose of miniaturization.

However, in the simplified process, the filter element is mainly soldered on the circuit board, and terminals and pins required by the network connector are disposed on the circuit board. Therefore, the terminals and the pins themselves are liable to lose sufficient structural strength so as to provide the capability of plugging or soldering the network connector.

In view of the above, the present application provides a method for effectively improving the above-mentioned deficiencies, and the method is a research and study that is applied in combination with the theory.

Furthermore, the two engaging portions 31 extend upward from the rear side of the circuit board 1 to correspond to the two vertical slot seats 22 of the assembling portion 21, and respectively have sliders 310 for engaging in the vertical slots 220; in the embodiment of the present application, the sliding block 310 may be in a shape of a "convex" with a wider lower protrusion 311 and a narrower upper protrusion 312, and the vertical groove 220 has a lower groove 221 matching with the lower protrusion 311 and an upper groove 222 matching with the upper protrusion 312, so that the combination strength between the two can be improved by the matching design in shape. While in other possible embodiments, for example: the sliding block 310 may also be a dovetail type, and the vertical slot 220 is a dovetail slot matching with the sliding block.

In addition, in order to make the two engaging portions 31 capable of being preliminarily positioned with the rear side of the circuit board 1, notches 13 corresponding to the two engaging portions 31 may be formed on the rear edge of the circuit board 1 in a concave manner.
