Description

Technical Field

[0001] The present application relates to the technical field of tooling and fixtures, and in particular to an electrical connector installation tooling. Background Art

[0002] The electrical connector needs to be installed in the mounting hole of the filter housing, and the electrical connector and the mounting hole of the filter housing need to be interference fit. Currently, there are two commonly used installation methods for interference fit: press-in assembly method and temperature difference assembly method. Since electronic components cannot withstand high temperatures, only press-in assembly method can be selected.

[0003] In the related art, the electric connector is first placed at the mounting hole of the filter housing, a flat plate is placed on top of the electric connector, and then the flat plate is hammered with a rubber hammer to press the electric connector into the mounting hole of the filter housing, thereby realizing the press-in assembly of the electric connector and the filter housing.

[0004] However, when using a rubber hammer to hit the flat plate, it is easy to make mistakes and injure the operator. The force of the hammer cannot be accurately controlled. When the force is small, the electrical connector cannot be installed properly. When the force is large, the electrical connector is easily deformed. It is difficult to accurately guide the movement of the electrical connector during the hammering, which can easily cause the electrical connector to be installed improperly. During the hammering process, the vibration generated by the hammering causes the housing and the connector to move relative to each other, which can easily cause assembly difficulties. Bumps are likely to occur during the movement, affecting the appearance quality of the product. Utility Model Content
