detailed description

Below in conjunction with specific embodiment, further illustrate the present invention. It should be understood that these examples are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of the present application.

As shown in FIG. 1-4 , a pin-shearing jig for connectors includes a jig table 1 , a pressing hammer 3 and a pressing rod 4 . The jig table 1 has a square table structure as a whole, and there is a groove 2 on the table surface of the jig table 1, and the groove 2 is preferably arranged in the middle of the table top of the jig table 1. The bottom of the groove 2 is provided with several rows of jacks. Usually, the jacks are arranged in two rows or four rows, which can satisfy the simultaneous cutting of multiple connectors 9. The jacks are downward through holes. The size and position of the jacks are consistent with the The pins of the existing connectors 9 are matched, so that the connectors 9 of all specifications can pass therethrough smoothly.

The pressing hammer 3 is installed on one side of the table top of the jig table 1 through a hinge connection, and the extending direction of the pressing hammer 3 and the groove 2 are consistent and matched in shape. After inserting the connector 9 into the socket of the groove 2, lift the pressure hammer 3 by hand and place it lightly on the upper part of the connector 9, after cutting the connector 9, lift the pressure hammer 3 by hand Pull out the connector 9 smoothly. In order to press the hammer 3 on the connector 9 conveniently, the groove 2 is set as a dovetail groove, and the groove is wide at the top and narrow at the bottom.

The pressure rod 4 is a rectangular ring structure, one end is connected to the other side of the fixture table 1 through a hinge structure, and a connecting rod 5 is interspersed on the pressure rod 4, and the connecting rod 5 is parallel to the extending direction of the groove 2, and the connecting rod 5 Two ends respectively connect a connecting rod 6, and the two ends of connecting rod 6 lower ends and blade 7 are connected by hinge, and the length of blade 7 corresponds to groove 2, and is horizontally installed in the chute below fixture table 1 table top. Rotating the pressing rod 4 downwards can drive the blade 7 to perform horizontal translation, which is used to cut off the redundant part of the connector 9 . The connecting position of the connecting rod 5 and the pressing rod 4 can be set along one end of the hinge structure close to the pressing rod 4. This design utilizes the principle of leverage and saves the effort of the scissors operation. Boss 8 is provided under the table of fixture table 1, and the starting position of boss 8 is set on the other side below the groove 2 away from the starting position of blade 7. Bottom 8 can prevent blade 7 from being damaged beyond the limit position when trimming connector 9 device.
