Description

Technical Field

[0001] The utility model relates to the technical field of structural application in the machinery industry, in particular to a plug used for socket jack detection. Background Art

[0002] At present, in the production process of sockets, front-end assembly workers frequently miss the socket sleeves or the socket sleeves are deformed due to the smaller opening. Previously, visual inspection was mainly done by employees, but they may be tired or inattentive, so this method cannot be 100%, and customers frequently complain about this problem. In addition, the existing test plugs are made of copper, which is not wear-resistant and has a service life of only 100,000 times. If the production line is not replaced in time, the product will be damaged, and even the safety protection door structure will be damaged, bringing safety risks to the product. At the same time, frequent plugging and unplugging during the test process will generate a large amount of copper chips, which will accumulate in the dead corners of the equipment test movement mechanism and cause equipment failure. Utility Model Content

[0005] Further: In the above-mentioned plug for socket jack detection, the conductive sheet is in the shape of a kitchen knife, and the conductive sheet includes a knife body and a knife handle. The knife handle and the vertical end of the wear-resistant sheet are arranged on both sides of the conductive surface, and the exposed insulating isolation sheet between the conductive sheet and the wear-resistant sheet is Z-shaped. This smooth track-changing structural design protects the insulating isolation sheet from wear and effectively prevents internal short circuit of the plug.

[0006] The non-conductive load-bearing structure, the insulating spacer and the conductive sheet are connected by plastic screws, which fully ensure a secure connection and ensure that the conductive sheet is completely insulated from the insulating spacer and the non-conductive load-bearing structure.

[0007] The top of the conductive sheet is provided with an inclination angle for crimping the wire, and the inclination angle is 60 degrees, so as to ensure that the wire and the conductive sheet are connected smoothly and keep the appearance neat.

[0008] Alternatively: the outermost layer of the insulating spacer is provided with a recess for accommodating the conductive sheet, and the upper end of the outermost layer of the insulating spacer is provided with a wire groove, which is communicated with the wire groove on the upper end of the conductive surface.

[0009] The top of the entire plug is provided with a limit head for insertion limit, the cross-sectional area of ​​the limit head is larger than the cross-sectional area of ​​the top of the non-conductive load-bearing structure, and the plug is inserted into place during the detection process. The limit head is provided with a wire storage hole to maintain a good appearance.

[0010] Of course, the conductive sheet and L-shaped wear-resistant sheet of the plug of the utility model can also be made of high-strength steel, and the surface is polished. Combined with the track-changing design, the whole process greatly reduces the generation of metal debris, and also greatly improves the service life of the plug of the utility model. The L-shaped wear-resistant sheet and the non-conductive load-bearing structure can be integrally formed or assembled separately.

[0011] Compared with the prior art, the plug for socket detection includes a strip-shaped non-conductive load-bearing structure, and any wide side of the non-conductive load-bearing structure is set as a conductive surface, that is, only one side is a conductive surface, and the other sides are insulating surfaces. A wire groove is provided at the upper end of the conductive surface, and an L-shaped wear-resistant sheet is provided at the lower end of the conductive surface. An insulating spacer is spread between the upper and lower ends of the conductive surface, and a conductive sheet is provided on the outermost layer of the insulating spacer. The area size of the conductive sheet is smaller than the area size of the insulating spacer, and the insulating spacer is exposed around the periphery of the conductive sheet; the conductive sheet is connected to a wire connected to the tester, and the wire is clamped on the wire groove. The plug ensures that the missing socket / deformed socket defective products can be tested out during the test process. It eliminates the visual inspection work of employees and reduces the work intensity of employees. The plug is applied to the production and testing process of electrical socket products, improves the quality of product shipments, reduces the difficulty of quality management, has a good fool-proof and error-proofing effect, and meets the needs of automated production.

The top of the conductive sheet is provided with an inclination angle for crimping the wire. The inclination angle is 60 degrees. The outermost layer of the insulating spacer 4 is provided with a pit 8 for accommodating the conductive sheet. The upper end of the outermost layer of the insulating spacer 4 is provided with a wire groove 2. The top of the entire plug is provided with a limit head 9 for inserting and limiting, and the cross-sectional area of ​​the limit head is larger than the cross-sectional area of ​​the top of the non-conductive load-bearing structure. The limit head is provided with a wire receiving hole 10.

[0020] The working principle of the plug test process of this embodiment is as follows Figure 3As shown: the ground electrode sheet 11 on the socket jack is in a folded shape, the socket 12 is in a U shape, and there is a bent contact spring on the left side of the U shape. Under normal product conditions, a socket is installed in the socket jack. During testing, the plug of this embodiment is directly inserted into the U-shaped socket 12. The current coming out of the tester passes through the wire 6 crimped with the conductive sheet 5--> conductive block sheet 5--> socket contact spring on the socket jack--> socket 12--> ground electrode sheet 11--> back to the tester PLC control circuit to form a test loop. If the socket 12 is missing or the socket 12 is deformed, such as the contact spring is not in the correct position, the contact spring of the socket 12 will not be able to contact the conductive sheet 5 of the plug, so that the current loop cannot be formed.
