Description

electrical connector

【Technical field】

The utility model relates to an electric connector, in particular to an electric connector with a terminal protection component.

【Background technique】

With the development trend of the electronic industry, in order to fully reduce the area of the circuit board occupied by the electrical connector, the industry often adopts the method of stacking several electrical connectors up and down; however, when the electrical connectors are stacked up and down, the electrical connectors on the upper layer The conductive terminals of the connector must be lengthened, so when the electrical connector is assembled on the circuit board, due to the long conductive terminals, it is easy to be moved upward by the upward resistance force of the circuit board, resulting in deformation of the conductive terminals. The collision of the upper layer is also likely to cause deformation of the upper conductive terminal and cause installation troubles.

Since the first conductive terminal is installed in the first socket on the upper layer of the insulating body, the length of the first conductive terminal is longer. In order to prevent the conductive terminal from moving upward, the electrical connector is arranged on the horizontal part of the uppermost conductive terminal. There is an insulating block installed on the insulating body, and the insulating block prevents the uppermost conductive terminal from moving upward.

However, the horizontal portions of the first conductive terminals are arranged in two rows along the vertical direction of the insulating body, and the insulating block can only prevent the uppermost horizontal portion from moving upwards. When the electrical connector is installed on the circuit board, the first The horizontal part of a conductive terminal located on the lower layer will inevitably move upward due to the abutment of the circuit board, so it is easy to cause deformation of the first conductive terminal located on the lower layer; in addition, the upward movement of the first conductive terminal located on the lower side is easy to resist to the first conductive terminal located on the upper layer to cause signal crosstalk between the upper and lower rows of terminals.

Therefore, it is necessary to modify the existing electrical connectors to overcome the above defects.
