Description

Technical Field

[0001] This utility model relates to connector assembly tool technology, and in particular to a fixture for accurately assembling rubber plugs into the interior of an oil-proof connector. Background Technology

[0002] Oil-resistant connectors are widely used in humid and oily working environments such as automobiles and construction machinery. The assembly quality of the internal rubber plug directly affects the connector's oil and water resistance and sealing performance. Currently, rubber plug assembly is mostly done manually. The operator needs to hold a pressing rod and the connector, and use the pressing rod to press the rubber plug, which is mounted on the wiring harness, into the connector.

[0003] This traditional assembly method has significant drawbacks: First, the connector lacks stable positioning during assembly, making it prone to displacement or wobbling, leading to misalignment of the rubber stopper and affecting the sealing effect. Second, the uneven axial force applied manually may cause deformation or damage to the rubber stopper, or leave sealing hazards due to incomplete pressing. Third, the operation relies on manual experience, resulting in low assembly efficiency and poor consistency, making it difficult to meet the needs of mass production. Therefore, there is an urgent need to design a dedicated assembly fixture to solve the problems of inaccurate positioning, uneven force distribution, and low efficiency in existing manual assembly methods. Utility Model Content

[0021] Example:

[0022] like Figure 1 As shown, in one embodiment of the present invention, the oil-proof connector plug assembly fixture includes a fixture body 1, on which a groove 2 for positioning the connector is provided. The size of the groove 2 matches the shape of the connector to ensure that the connector will not wobble laterally after being placed in.

[0023] like Figure 2 As shown, the fixture body 1 has a wedge-shaped cavity 3, a wedge-shaped cavity 4, a spring mounting cavity 5, a pressure rod insertion cavity 6, and a pressure rod insertion cavity 7 inside. The wedge-shaped cavity 3 and the wedge-shaped cavity 4 are located on the left and right sides of the groove 2, respectively. The spring mounting cavity 5 is laterally connected to the wedge-shaped cavity 3 and the wedge-shaped cavity 4. The pressure rod insertion cavity 6 is vertically connected to the wedge-shaped cavity 3, and the pressure rod insertion cavity 7 is vertically connected to the wedge-shaped cavity 4.

[0024] like Figure 2 As shown, the limiting mechanism consists of limiting rod 8, limiting rod 9, pressure rod 10, pressure rod 11, and spring 12. Limiting rod 8 is hinged within wedge cavity 3, and limiting rod 9 is hinged within wedge cavity 4. Limiting rod 8 extends from the upper end of wedge cavity 3 to form hook structure 13, and limiting rod 9 extends from the upper end of wedge cavity 4 to form hook structure 14. Hook structures 13 and 14 extend towards groove 2 to fasten the top of the connector. Spring 12 is installed in spring mounting cavity 5, with its two ends abutting against the inner bottom ends of limiting rod 8 and limiting rod 9, respectively, providing clamping force for limiting rods 8 and 9. The first pressure rod 10 is movably inserted into the first pressure rod insertion cavity 6, with its inner end abutting against the outer side of the bottom end of the first limiting rod 8. The second pressure rod 11 is movably inserted into the second pressure rod insertion cavity 7, with its inner end abutting against the outer side of the bottom end of the second limiting rod 9. The first pressure rod 10 is provided with an axial strip hole 15. The first pressure rod insertion cavity 6 is provided with a limiting shaft 16, which is inserted into the strip hole 15. The second pressure rod 11 is provided with an axial strip hole 17. The second pressure rod insertion cavity 7 is provided with a limiting shaft 18, which is inserted into the strip hole 17, thereby realizing the axial movement limitation of the first pressure rod 10 and the second pressure rod 11.

[0025] The fixture body 1 also has a push rod insertion cavity inside, which is arranged along the axial direction of the groove 2 and communicates with the groove 2. The pressing mechanism consists of a push rod 20 and a spring (not shown). The push rod 20 is movably inserted into the push rod insertion cavity. One end of the push rod 20 that extends into the groove 2 is integrally formed with a pressing block 22. The end of the pressing block 22 is provided with a pressing structure 23 that matches the connector tail end slot, and the top is provided with a wire harness positioning groove 24 that corresponds to the connector tail end wire harness. One end of the push rod 20 that extends out of the fixture body 1 is fixedly connected to a push handle 25. The spring is arranged along the insertion direction of the push rod 20 and is located between the push handle 25 and the fixture body 1. Both ends are fixedly connected to the push handle 25 and the fixture body 1, respectively.

[0026] It should be noted that the top sides of hook-shaped structure 13 and hook-shaped structure 14 are provided with oppositely arranged chamfers to facilitate the insertion of the connector into the slot 2. During the guiding process, hook-shaped structure 13 and hook-shaped structure 14 automatically overcome the elastic force of spring 12 and turn to the outside. After the connector is inserted into the slot 2, hook-shaped structure 13 and hook-shaped structure 14 automatically reset under the elastic force of spring 12 and fasten the top of the connector.

[0027] During assembly, press the connector into slot 2. Hook-shaped structure 13 and hook-shaped structure 14 clamp the connector under the elastic force of spring 12. Then, insert the wire harness into the wire harness positioning slot 24. Next, push the push handle 25, which drives the pressing block 22 to move towards the tail end of the connector through the push rod 20. The pressing structure 23 fits into the slot at the tail end of the connector, applying a uniform axial force to smoothly press the rubber plug into the inside of the connector. Release the push handle 25, and the push rod 20 returns to its original position under the action of spring 2. Finally, press the pressure rod 10 and pressure rod 11 to remove the assembled connector.

[0028] Therefore, this utility model has the following advantages:

[0029] Solving the problem of inaccurate positioning: The connector is precisely positioned by the slot, and the hook structure of the limiting mechanism clamps the connector from both sides to prevent the connector from shifting or falling off during assembly, and ensures the accurate pressing path of the rubber plug.

[0030] Solving the problem of uneven force distribution: The pressing mechanism applies axial force through the push rod. The pressing structure of the pressing block matches the connector tail slot, so as to achieve uniform force transmission, avoid deformation or damage of the rubber plug, and ensure that the pressing is in place.

[0031] Improve assembly efficiency and consistency: No need to rely on manual experience, standardized operation process, wire harness positioning groove further ensures assembly accuracy by limiting the wire harness, which can significantly improve assembly efficiency and reduce the defect rate in mass production.

[0032] Improved ease of operation: Spring 1 enables automatic limiting of the limiting mechanism, and Spring 2 enables automatic reset of the push rod, reducing operation steps and labor intensity.

[0033] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
