Description

Technical Field

[0001] This utility model relates to connectors for wire harnesses, specifically to production equipment for female connectors. Background Technology

[0002] Cables consist of several wire bundles. The female connector is used for electrical connection between cables or between a cable and electrical equipment. Female connectors are mass-produced as standard parts with a fixed number of sockets, such as ten. In practical applications, the number of wire bundles in a cable varies, requiring a different number of sockets. For example, only six sockets of the female connector may be needed, leaving the other four unused. Furthermore, even if the number of unused sockets is the same for different cables, their positions may differ. Workers often use plastic parts to seal the unused sockets. Over time, workers' ability to identify these sockets decreases, and when faced with a cluster of female connector sockets, they may insert the plastic parts into the required sockets instead of the unused ones, resulting in defective female connectors. Utility Model Content

[0003] The technical problem solved by this utility model is that due to long working hours, workers' identification ability decreases, and they may block the required sockets in the female plug instead of the unused sockets, resulting in defective female plugs.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a sealing mechanism for unused female connector holes in a wire harness, including a slide rail mounted on a frame, a female connector positioning seat fitted on the slide rail, and a vertical cylinder mounted on the frame. The frame is provided with a feeding station and a pressing station. The female connector positioning seat can linearly move between the feeding station and the pressing station. The vertical cylinder is located at the pressing station and is connected to a pressing block. The female connector positioning seat is equipped with a blockage identification cover. The female connector is positioned in the female connector positioning seat. The blockage identification cover is closed on the top of the female connector. The blockage identification cover has the same number of identification holes as the unused female connector holes. The identification holes are aligned one by one with the unused female connector holes. The inner diameter of the identification holes is smaller than the inner diameter of the unused female connector holes.

[0005] According to the above technical solution, at the loading station, the female plug is positioned in the female plug positioning seat. The worker inserts a colored plug (cylindrical plastic part) into an unused socket. The plug is not completely submerged in the socket; some of it protrudes upwards. Then, the worker places the plug identification cover on top of the female plug, also on top of the plug. Since the number of identification holes is the same as the number of unused holes on the female plug and they are aligned vertically, the worker can determine whether the plug is inserted into the correct unused hole by observing whether the color of the plug is present in all the identification holes. If not, the worker can immediately remove the plug identification cover and correct the plug.

[0006] If the worker can see the color of the blockage material by observing all the identification holes, it indicates that the blockage material is inserted into the correct unused hole. The worker then pushes the female connector positioning seat from the loading station to the pressing station. The vertical cylinder activates, driving the pressure block to descend. The pressure block presses onto the blockage material identification cover, pressing the blockage material into place so that it is completely submerged in the unused hole of the female connector. After the vertical cylinder rises and resets, the worker pulls the female connector positioning seat back from the pressing station to the loading station, removes the blockage material identification cover, and then removes the female connector.

[0007] The female connector positioning seat has a countersunk hole with a cylindrical protrusion inside. A square recessed groove is located at the top of the countersunk hole. The female connector fits into the countersunk hole, the cylindrical protrusion fits into the cavity of the female connector, and the flange of the female connector fits into the square recessed groove. A plugging clearance hole is located at the top of the cylindrical protrusion. When the plugging material is fully pressed into the unused position of the female connector, the front end face of the female connector is flush with the front end face of the plugging material. However, the rear end face of the plugging material protrudes backward from the rear end face of the unused position. The plugging clearance hole accommodates the plugging material protruding backward from the rear end face of the unused position. The flange of the female connector fits into the square recessed groove, ensuring accurate positioning of the female connector on the female connector positioning seat.

[0008] The material blockage identification cover has a cavity for receiving the top of the female connector, and a square structure at the bottom. An identification hole is located at the top of the cover and communicates with the cavity for receiving the top of the female connector. When the material blockage identification cover is closed on the top of the female connector, the top of the female connector, protruding upwards from the positioning seat, is received in the cavity for receiving the top of the female connector. The square structure is aligned vertically with the flange of the female connector, thus positioning the material blockage identification cover.

[0009] The top of the cylindrical protrusion is provided with a positioning hole, and the top cavity of the female plug is provided with a positioning pin that mates with the positioning hole. The blockage identification cover is placed on the top of the female plug, the top of the female plug mates with the top cavity of the female plug, and the positioning pin is inserted into the positioning hole, so the blockage identification cover is accurately positioned.

[0010] The female connector positioning seat is mounted on a sliding plate. The bottom of the sliding plate has a slider that cooperates with the slide rail. A handle is installed on the sliding plate. The handle makes it easy for workers to push and pull the female connector positioning seat between the loading station and the pressing station.

[0011] The frame includes a bottom plate, a vertical plate fixed to the bottom plate, and a top plate fixed to the top of the vertical plate. A slide rail is mounted on the bottom plate, and a vertical cylinder is mounted on the top plate. Vertical guide rails are provided on the vertical guide rails, and lifting blocks are slidably fitted onto these guide rails. Pressure blocks are mounted on the lifting blocks. Driven by the vertical cylinder, the lifting blocks move up and down along the vertical guide rails.

[0012] Limiting blocks are installed on the upright plate. These blocks abut against the lifting block, limiting its minimum height; they also abut against the female insertion positioning seat, limiting its backward displacement. When the pressing block presses the blockage identification cover into place, the top surface of the lifting block abuts against the limiting block. When the female insertion positioning seat is pushed into place, it abuts against the front surface of the limiting block.

[0013] Transparent panels are installed on the front, left and right sides of the rack, and a female plug positioning seat clearance channel is opened on the transparent panel at the front of the rack.

[0014] This utility model's blockage identification cover helps workers quickly and effectively identify whether the blockage is properly installed. If the blockage is installed correctly, the pressure block helps the worker fully press the blockage into the unused hole of the female connector. If the blockage is not installed correctly, the worker can correct it immediately. This utility model can effectively improve the yield rate of female connectors and avoid rework.
