Description

Technical Field

[0001] The utility model belongs to the technical field of wire harness assembly, and in particular relates to a lifting and pulling type wire plugging fixture. Background Art

[0002] In the wiring harness assembly, a common assembly method is to insert the wire into a plastic connector with a metal conductive sleeve, and then press the plastic connector sideways to fix the wire. Since there is a metal contact at the head end of the wire, and there are barbs on the metal contact, under normal circumstances, after the metal contact is inserted into the metal conductive sleeve of the plastic connector, the barbs will limit the position, so that the wire will not be easily pulled out. This can effectively avoid unstable wire connection or loose metal contacts caused by incomplete insertion. After pressing on the side, poor contact is likely to occur, or the wire will fall off directly.

[0003] However, in actual operation, although there are barbs on the metal contacts, when the wire is inserted into the metal contacts, if the insertion depth is not enough, the barbs may not be firmly fixed, and the wiring harness assembly requirements will not be met. The current assembly auxiliary fixture only has a side pressing structure, which cannot determine whether the metal contacts of the wire are plugged in place. Utility Model Content

[0004] In view of the above problems, the purpose of the present utility model is to provide a lifting and pulling wire insertion fixture, aiming to solve the above technical problems.

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0019] like Figure 1-3As shown, the pull-type wire insertion fixture provided in this embodiment includes a base 2 and a top seat 1, the top seat 1 is connected to the base 2 through an elastic component 3, a pressure component 4 is installed on the top seat 1, and the pressure component 4 includes a lower pressure plate 41, a storage groove 11 and an avoidance groove 12 are opened on the top seat 1, the storage groove 12 is located below the lower pressure plate 41, and a pressing component 5 is also provided on one side of the top seat 1, and the pressing component 5 is arranged toward the storage groove 11 through the avoidance groove 12, and a detection sensor 13 is also provided in the storage groove 11.

[0020] This plug-in fixture is used to assist the plugging and pressing and fixing of wires and plastic connectors. The head end of the wire has a metal connector with barbs, and the plastic connector has a metal conductive sleeve. Under normal assembly requirements, after the wire is inserted into the plastic connector, the metal connector of the wire and the metal conductive sleeve of the plastic connector are limited, and finally the metal connector and the metal conductive sleeve are clamped by pressing from the side of the plastic connector.

[0021] The method of using this plug-in fixture is as follows: first, place the plastic connector in the storage slot. The opening shape of the storage slot matches the plastic connector and can be set to be compatible with a variety of plastic connectors without shaking; at this time, the detection sensor (the type of detection sensor is not limited in this embodiment) detects that the plastic connector is in place, and automatically triggers the pressing component to press and fix the plastic connector; then the operator inserts the wire into the plastic connector from top to bottom, and then pulls the wire upward. Due to the limiting effect of the barb, under normal circumstances, the top seat will be lifted up together, indicating that the metal contact of the wire has been inserted in place and meets the assembly requirements; then release the wire and the top seat automatically returns to its position, and finally triggers the pressing component to press the side of the plastic plug to complete the assembly. This embodiment adopts a manual foot-operated triggering method. If the metal connector of the wire is not inserted into place, the wire will fall off the plastic connector when the wire is pulled, so this method can ensure that the composite quality requirements of each plug-in assembly.

[0022] In the figure, as a specific structure, the pressure assembly 4 includes a hollow support 42 arranged on the top of the top seat 1, the lower pressure plate 41 is hinged to the hollow support 42, the tail end of the lower pressure plate 41 has a short slot 43, and the pressure assembly 4 also includes a small cylinder 44 installed in the top seat 1, and the driving end of the small cylinder 44 has a connecting pin and the connecting pin is located in the short slot 43. When the detection sensor detects that the plastic joint is in place, the small cylinder automatically drives its driving end to push up, and the connecting pin slides in the end slot, thereby completing the downward pressing operation of driving the lower pressure plate. In addition, there is a stop pin on the hollow support 42, which is used to limit the maximum pushing distance of the small cylinder to avoid crushing the plastic joint.

[0023] The function of the elastic component 3 is to apply a pulling force to the top seat when the wire is pulled. Under standard assembly requirements, when the wire is pulled, the top seat will be lifted together, which can overcome the force of the elastic component. If no elastic component is provided, it is difficult to control the pulling force on the wire and it is not easy to operate. Figure 4 As shown, the elastic component 3 provided in this embodiment includes a guide rod 31, and the two ends of the guide rod 31 are limit blocks 32. The top seat 1 and the base 2 are both provided with corresponding through stepped holes, wherein a spring 33 is arranged on the guide rod 31 located in the stepped hole of the base. The lifting wire is spring compressed, and the guide rod moves stably.

[0024] After the wires are inserted, the pressing assembly presses the side of the plastic connector from the avoidance groove to press and fix the plug-in position. In the figure, the pressing assembly 5 includes a mounting block 51 fixed to one side of the base 2, and a pressing cylinder 52 is fixed to the mounting block 51. A cushion block 54 is fixed to the output end of the pressing cylinder 52 through a pair of nuts 53, and a push block 55 is provided on the cushion block 54 facing the storage groove. In this structure, the pressing cylinder drives the push block 55 to press. In addition, an adjustment groove is provided on the cushion block 54. The pair of nuts 53 pass through the adjustment groove 56 and are locked to the output end of the pressing cylinder 52, which can conveniently adjust the position of the push block 55 to adapt to different types of plastic connectors.

[0025] Finally, the pull-type wire insertion fixture also includes a counter 6 located on one side of the base, which can count the number of times the cylinder is pressed, that is, the number of wire insertion operations completed in the current time period.

[0026] In summary, the utility model can ensure that the wire insertion operation meets the assembly requirements and improve the yield rate of the wiring harness product by designing a wire insertion fixture. The structure design is simple and practical.

[0027] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
