Technical Field

[0001] The utility model relates to the field of connectors, and particularly to a positioning tool for connector pins. Background Art

[0002] A connector is also called a plug-in unit, a plug, and a socket, generally referring to an electrical connector, that is, a device used to connect two active devices to transmit current or signals. The elastic contact member in the connector is a key part, and its structure directly affects the contact performance of the connector.

[0003] Currently, when connecting a wire harness to a connector, it is mostly done by manual wiring. During mass production, it is inevitable that the staff will experience visual fatigue after staring at the wiring for a long time, resulting in holding the connector backwards and all the wire harness pin positions being inserted backwards. Such defective products are also inconvenient to identify, leading to the outflow of defective products to the client. If the client assembles the wire harness with incorrect pins onto the equipment, it will cause incorrect signal transmission or power short circuit in the equipment, burning out the equipment and causing serious safety accidents. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the defect that in the existing technology during the connector wiring process, reverse insertion is likely to occur, resulting in defective products flowing into the market and causing serious harm to customers, and to provide a positioning tool for connector pins.

[0005] The purpose of the utility model can be realized by the following technical solutions:

[0006] A positioning tool for connector pins is used for positioning the connector when the wire harness is connected to the connector. The tool includes a fixed base and a cover plate connected to each other. The fixed base is provided with a receiving groove, and a plugging hole blind pin is provided at the bottom of the receiving groove. The cover plate is located above the receiving groove, and a wire passing hole is provided on the cover plate. The wire passing hole is matched with the wire harness.

[0008] Preferably, guiding grooves are provided on both sides of the receiving groove, and the guiding grooves are matched with guiding blocks on both sides of the connector.

[0009] Preferably, the height of the plugging hole blind pin extending from the bottom of the receiving groove is 0.5 - 0.7 times the depth of the pin hole on the connector.

[0010] Preferably, the plugging blind pin is embedded in the receiving groove, and the plugging blind pin is perpendicular to the bottom of the receiving groove.

[0011] Preferably, a lock catch is provided on the fixed base. The lock catch is located on one side of the fixed base. One side of the cover plate is rotatably fixed to the side of the fixed base away from the lock catch, and the lock catch is interconnected with the cover plate.

[0012] Preferably, a hinge is provided between the fixed base and the cover plate. One side of the hinge is fixed to the fixed base, and the other side is fixed to the cover plate.
