Description

Technical Field

[0001] This invention relates to the field of PTH connector assembly technology, and in particular to an assembly fixture for preventing connector screws from rotating. Background Technology

[0002] During the assembly of PTH connectors, screws need to be installed on both sides of connectors of different sizes according to requirements.

[0003] To meet assembly requirements, holes need to be drilled on the assembly fixture according to the dimensions of each PTH connector for assembly. However, current assembly fixtures still have the following problems:

[0004] 1. Since the positioning pins on the PTH connector are crimped, if a normal-hole assembly fixture is used to assemble the screws, the positioning pins of the connector will rotate, causing the screws to not be assembled in place.

[0005] 2. Since PTH connectors come in different sizes, the sizes of the connector openings on the fixtures must also correspond one-to-one, which means that multiple fixtures with different opening sizes are needed, increasing costs. Summary of the Invention

The positioning connecting groove is provided with a clamp positioning block latch that movably connects with the positioning post slot on the connector to prevent the positioning post from rotating during screw installation.

[0010] The fixing screw hole is located at the bottom of the fixture positioning block, the positioning adjustment groove is located on the fixture seat, the positioning block locking screw is movably located in the positioning adjustment groove, and the upper end of the positioning block locking screw is movably connected to the fixing screw hole to lock or unlock the fixture positioning block, thereby adjusting the position of the fixture positioning block according to the size and distance of the positioning posts on both sides of the PTH connector.

[0011] In a preferred embodiment of the present invention, the positioning connection groove includes a positioning post connection groove body for placing the lower part of the connector positioning post and a guide groove body, wherein the guide groove body is disposed above the positioning post connection groove body.

[0012] In a preferred embodiment of the present invention, the diameter of the guide groove is larger than the diameter of the positioning post connecting groove.

[0013] In a preferred embodiment of the present invention, the clamp positioning block buckle is vertically disposed in the positioning post slot, and its top does not exceed the top surface of the positioning post connecting groove.

[0014] In a preferred embodiment of the present invention, the fixture seat is provided with a guide groove, the positioning adjustment groove is provided at the bottom of the guide groove, and the fixture positioning block is movably disposed within the guide groove.

[0015] In a preferred embodiment of the present invention, the fixture seat below the positioning adjustment groove is provided with a movable groove for facilitating the installation of the positioning block locking screw.

[0016] The beneficial effects of this invention are: by using the positioning connection groove and the clamp positioning block buckle to fix the connector positioning post, the assembly efficiency and accuracy are improved, and the spacing between the clamp positioning blocks can be adjusted by adjusting the positioning block locking screws to adapt to connectors with different positioning post spacing sizes, thereby improving the practicality of the clamp.

[0024] The fixture positioning block is movably mounted on the fixture base, and the positioning connecting groove is located on the upper part of the fixture positioning block for connecting the positioning post 10 of the PTH connector 9, thereby positioning the assembly position of the connector. The positioning connecting groove is provided with a fixture positioning block buckle that is movably connected to the positioning post slot on the connector, so that the positioning post slot is locked on the fixture positioning block buckle to prevent the positioning post from rotating when the screw 11 is installed.

[0025] More preferably, the positioning connection groove includes a positioning post connection groove for placing the lower part of the connector positioning post and a guide groove, wherein the guide groove is disposed above the positioning post connection groove.

[0026] More preferably, the diameter of the guide groove is larger than the diameter of the positioning post connecting groove.

[0027] More preferably, the clamp positioning block buckle is vertically disposed in the positioning post slot, and its top does not exceed the top surface of the positioning post connecting groove.

[0028] The fixing screw hole is located at the bottom of the fixture positioning block, and a pair of positioning adjustment slots are arranged opposite to each other on the fixture seat. The positioning block locking screw is movably disposed in the positioning adjustment slot, and the upper end of the positioning block locking screw is movably connected to the fixing screw hole to lock or unlock the fixture positioning block. This allows the position of the fixture positioning block to be adjusted according to the size and distance of the positioning pins on both sides of the PTH connector, thereby improving the adaptability of the fixture.

[0029] More preferably, the fixture base is provided with a guide groove 8, the positioning adjustment groove is provided at the bottom of the guide groove, and the fixture positioning block is movably disposed in the guide groove, so as to limit and guide the position adjustment of the fixture positioning block and improve the assembly accuracy.
