Description

Technical Field

[0001] This invention relates to the field of electrical connector technology, and in particular to a high-density connector pick-and-place tool. Background Technology

[0002] With the increasing demand for miniaturization and high density in aerospace equipment, the contact size of electrical connectors is gradually decreasing, and the spacing is becoming more compact. Traditional plastic pick-and-place tools lack sufficient strength due to their thin walls, failing to meet actual pick-and-place requirements. Furthermore, while plastic tools have good elasticity, they are prone to breakage under high-intensity operation, leading to contact pick-and-place failure or damage. Therefore, we propose a high-density connector pick-and-place tool. Summary of the Invention

[0003] The main objective of this invention is to provide a high-density connector pick-and-place tool that can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A high-density connector delivery tool includes an infeed end, an outfeed end, and a handle; the infeed end and the outfeed end are respectively fixedly connected to the handle by adhesive; the infeed end and the outfeed end are both integrally formed from a metal sheet by a stamping process, and are used to respectively deliver the contact after crimping the wire into the connector or remove it from the connector. The feeding end has a three-section structure, which includes, from the front end to the rear end, a first rear end that adapts to the size of the contact part, a first front end that enhances the overall strength, and a first middle part that connects the first front end and the first rear end. The extraction end has a three-section structure, consisting of a second rear end, a second front end for enhancing overall strength, and a second middle section connecting the second front end and the second rear end, from front to rear.

[0005] Preferably, the feed end and the take-out end are made of stainless steel material for springs.

[0006] By adopting the above technical solution, the stainless steel material for the spring has excellent elastic deformation ability and fatigue resistance. It can effectively rebound and reset during repeated insertion into narrow cavities, avoiding plastic deformation or breakage, thereby significantly improving the adaptability and overall service life of the tool in the narrow space of high-density connectors.

[0007] Preferably, the contact area of ​​the first rear end portion is provided with a first rounded corner.

[0008] By adopting the above technical solution, the first rounded corner can reduce stress concentration and frictional resistance between the feed end and the contact or connector inner wall, achieve a smooth transition during the pushing process, prevent scratching the contact surface or jamming, and improve the smoothness and reliability of the feeding operation.

[0009] Preferably, the middle part of the second rear end portion is provided with an opening groove, and the outer surface of the second rear end portion away from the second middle portion is provided with a second rounded corner that is open on both sides.

[0010] By adopting the above technical solution: the opening groove gives the front end of the extraction end the necessary elastic opening ability, so that it can open the internal claws to unlock the contact when the connector is inserted, while the second rounded corners of the opening on both sides facilitate alignment and guide the end into the cavity, while reducing the risk of scratching during the extraction process and improving the success rate of extraction.

[0011] Preferably, the handle is made of plastic material and has a non-slip texture on its surface.

[0012] By adopting the above technical solutions, the plastic handle is lightweight and has good insulation. Combined with the anti-slip texture on the surface, it can enhance the operator's grip stability, especially in confined or high-altitude working environments, effectively preventing the tool from slipping and improving operating safety and comfort.

[0013] Preferably, the handle has an internal mounting groove, and the rear end of the feed end or take-out end is inserted into the mounting groove and fixed by adhesive.

[0014] By adopting the above technical solution, the mounting groove and the rear end of the metal end form a mating structure, and are further fixed with adhesive. This not only ensures the connection strength between the metal functional components and the handle, but also facilitates manufacturing and assembly. At the same time, it avoids stress concentration or protrusion caused by riveting or welding, keeping the tool compact and aesthetically pleasing overall.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By designing the feed end and take-out end as three-section metal stamping structures with specific functions, and using stainless steel material for springs in one piece, the structural strength and elastic recovery capability of the tool under small size are significantly improved. Among them, the first rear end of the feed end is provided with a first rounded corner to facilitate the smooth pushing of the contact; the second rear end of the take-out end is provided with an opening groove and a second rounded corner with openings on both sides, which can open the connector claws to unlock during insertion, effectively solving the problems of easy damage and poor adaptability of traditional plastic tools, making the tool suitable for connectors with smaller apertures and higher density.

[0016] 2. The handle is made of plastic with anti-slip texture and has an internal mounting groove. The metal end is firmly fixed by a plug-in adhesive method, which not only ensures grip comfort and operational stability, but also achieves a reliable combination of metal functional components and ergonomic handle. At the same time, the feed and take-out functions are located on separate ends, which can be flexibly selected according to actual working conditions, greatly improving assembly and maintenance efficiency and reducing the risk of operational errors.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0022] Please see Figure 1-5 The present invention provides a technical solution: A high-density connector delivery tool includes an infeed end 1, an outfeed end 2, and a handle 3; the infeed end 1 and the outfeed end 2 are respectively fixedly connected to the handle 3 by adhesive; the infeed end 1 and the outfeed end 2 are both integrally formed from metal sheets by stamping process, and are used to respectively deliver the contact 5 after crimping the wire into the connector or remove it from the connector.

[0023] In this embodiment, the feeding end 1 has a three-section structure, which includes, from the front end to the rear end, a first rear end 13 adapted to the size of the contact member 5, a first front end 11 for enhancing the overall strength, and a first middle part 12 connecting the first front end 11 and the first rear end 13; the taking end 2 has a three-section structure, which includes, from the front end to the rear end, a second rear end 23, a second front end 21 for enhancing the overall strength, and a second middle part 22 connecting the second front end 21 and the second rear end 23; the feeding end 1 and the taking end 2 are made of stainless steel material for springs; the contact area of ​​the first rear end 13 is provided with a first rounded corner 14; the middle part of the second rear end 23 is provided with an opening groove 24, and the outer surface of the second rear end 23 away from the second middle part 22 is provided with a second rounded corner 25 that is open on both sides.

[0024] The above solution significantly improves the structural strength and elastic recovery of the tool in its small size by designing the infeed end 1 and the take-out end 2 as three-section metal stamping structures with specific functions and using stainless steel material for springs in one piece. The first rear end 13 of the infeed end 1 is provided with a first rounded corner 14 to facilitate the smooth pushing of the contact 5. The second rear end 23 of the take-out end 2 is provided with an opening groove 24 and a second rounded corner 25 with openings on both sides, which can open the connector claws to unlock during insertion.

[0025] In this embodiment, the handle 3 is made of plastic material and has anti-slip texture on its surface; the handle 3 has an installation groove inside, and the rear end of the end 1 or the end 2 is inserted into the installation groove and fixed by adhesive.

[0026] The above solution involves using a plastic handle with anti-slip texture and an internal mounting groove to securely fix the metal end with a plug-in adhesive method. This ensures both grip comfort and operational stability, while also achieving a reliable combination of the metal functional components and the ergonomic handle. Furthermore, the feed and take-out functions are located on separate ends, allowing for flexible selection based on actual working conditions. This significantly improves assembly and maintenance efficiency and reduces the risk of operational errors.

[0027] It should be noted that this invention is a high-density connector delivery tool, which is divided into two types during use: a delivery tool and a delivery tool, used for installation and maintenance scenarios respectively.

[0028] Insertion process: When using the insertion tool, place the contact body 5 with the crimped wire in the front end area of ​​the insertion end 1, and push the tool axially along the connector cavity by holding the handle 3; the front end of the insertion end 1 pushes the tail platform of the contact body 5, while the transition section and rear end of its three-section structure provide support strength, the rounded corner of the front end guides it to enter smoothly, and with the cooperation of the internal claw 4 structure of the connector, push the contact body 5 to the locking position; after it is in place, remove the insertion tool to complete the installation; Removal process: When using the removal tool, align the front opening slot of the removal end 2 with the tail end of the installed contact body 5 and push it in along the cavity; when the end contacts the platform of the contact body 5, the structure of its front opening slot 24 will elastically expand under the action of the pushing force, opening the internal claw 4 of the connector and releasing the lock; continue to push and pull out at the same time, and the contact body 5 along with the wire can be completely removed, which is convenient for subsequent maintenance or replacement. Throughout the process, the elasticity and precise dimensional design of the metal end ensure a good match with the contact part 5 and the cavity, while the handle 3 and the metal end are firmly connected by a plug-in adhesive, taking into account both ease of operation and structural reliability.
