Description

Technical Field

[0001] This utility model belongs to the field of connector processing technology, and in particular relates to a connector housing punching fixture. Background Technology

[0002] Connectors, also known as electrical connectors, are devices that connect two active devices to transmit current or signals. The male and female terminals, when in contact, can transmit information or current; hence, they are called connectors.

[0003] In the prior art, the punching fixture used for connector housings involves placing the connector housing to be processed at a specific position on the lower die base. Then, driven by the power drive unit, the upper die base is pushed downwards to punch the connector housing. Since the connector housing is placed on the lower die base manually, coupled with the shaking caused by the power unit of the upper die base, the punching position is inaccurate, affecting the punching quality.

The base is provided with a clearance groove that matches the connecting plate. The connector housing is placed in the positioning groove, and the positioning plate is lifted under the action of the positioning spring, thereby positioning the connector housing in the positioning groove. The lifting drive mechanism drives the stamping column to descend and punch holes in the connector housing, ensuring the accuracy of the punching position and ensuring the processing quality of the connector housing.

[0008] Furthermore, the surface of the positioning plate that contacts the connector housing is provided with a guide slope, and the guide slope gradually slopes outward from top to bottom towards the outside of the positioning plate, thereby facilitating the upward movement of the positioning plate to position the connector housing between the positioning plate and the positioning groove.

[0009] Furthermore, the connector has a groove on its side, and the positioning plate has a limiting strip that matches the groove.

[0010] Furthermore, the base is provided with a guide groove that matches the positioning plate, the positioning plate is installed in the guide groove, and the positioning plate can move up and down along the direction of the guide groove.

[0011] Furthermore, the lifting drive mechanism includes a lifting drive cylinder, the push rod of the lifting drive cylinder is connected to the lifting plate, the lifting drive cylinder is fixed to the fixed plate, the fixed plate is connected to several guide rods, and the several guide rods pass through the lifting plate and are connected to the base.

[0012] Furthermore, the opening of the positioning groove is located on the side of the base.

[0013] Furthermore, the positioning groove is connected to the waste discharge groove, the waste discharge groove corresponds to the stamping hole, and the waste discharge groove is connected to the waste discharge cavity.

[0014] The waste discharge chamber is equipped with a waste collection trough, which has a handle to facilitate the collection of waste material after punching.
