[0043] Next, in combination with the implementation manners of the present utility model, the technical solutions in the implementation manners of the present utility model will be clearly and completely described. Obviously, the described implementation manners are only a part of the implementation manners of the present utility model, rather than all of the implementation manners. Based on the implementation manners in the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0044] As Figures 1 to 7 shown, the guiding structure for the plug-in connectors of the present utility model includes a plug-in body 1, an alignment plate 2, a bottom plate 3, a cage 4, a first guide rod 5, a first spring 6, a bolt 7, a second guide rod 8, and a second spring 9, which are used to connect the connector 200 on the product for electrical performance detection;

[0045] The EOL detection tooling for vehicle parts of the present utility model includes the above-mentioned guiding structure for the plug-in connectors.

[0046] As Figures 1 to 5 shown, the plug-in body 1 is an electrical connection member, and electrical interfaces 101 are provided at both ends of the plug-in body 1; the alignment plate 2 and the bottom plate 3 are oppositely arranged at both ends of the plug-in body 1, and through holes 100 are provided in the alignment plate 2 and the bottom plate 3 corresponding to the electrical interfaces 101; both the alignment plate 2 and the bottom plate 3 are slidably connected to the plug-in body 1 to realize the relative approach or separation of the alignment plate 2 and the bottom plate 3;

[0047] In the above structure, in some electronic products, there are plug-in components. Therefore, when performing electrical detection, the connector of the detection wire harness cannot be directly plugged into the connector 200 of the product. A plug-in component is required to connect the detection wire harness and the connector of the product. Therefore, this guiding structure is provided.

[0048] During application, the connector at the end of the detection wire harness is plugged into the through hole 100 of the bottom plate 3, so that the connector at the end of the detection wire harness is plugged into an electrical interface 101 of the plug-in component body 1. Then, the detection wire harness and this guiding structure are moved towards the product together. At this time, the guiding plate 2 will first contact the product, and the connector 200 of the product will enter the through hole 100 of the guiding plate 2. As the wire harness moves, the connector 200 of the product will be plugged into another electrical interface 101 of the plug-in component body 1, thus realizing the electrical connection of the detection wire harness, the plug-in component body 1, and the product, and then performing electrical detection.

[0049] As Figure 6 shown, the through hole 100 on the guiding plate 2 is a tapered groove, and the diameter of the through hole 100 gradually decreases from the side away from the plug-in component body 1 to the side close to the plug-in component body 1.

[0050] In the above structure, by setting the through hole 100 on the guiding plate 2 as a tapered groove, it is convenient for guiding, so that the connector 200 of the product can slide into the through hole 100 to ensure the convenience of connection.

[0051] In some embodiments, the through hole 100 on the bottom plate 3 is also set as a tapered groove.

[0052] In some embodiments, the shape of the through hole 100 on the bottom plate 3 can be set to imitate the shape of the connector at the end of the wire harness.

[0053] Specifically, the cross-sectional area of the through hole 100 on the guiding plate 2 is smaller than the area of the end of the plug-in component body 1 facing the guiding plate 2.

[0054] In the above structure, after the distance between the guiding plate 2 and the plug-in component body 1 becomes smaller, the guiding plate 2 will abut against the end face of the plug-in component body 1, so that the connector 200 of the product can be directly guided into the electrical interface 101 to ensure accuracy.

[0055] As Figure 1 and Figure 2 shown, the cage 4 surrounds and is fixed to the plug-in component body 1; one end of the first guide rod 5 is slidably connected to the cage 4, and the other end is fixedly connected to the guiding plate 2; the first spring 6 is sleeved on the first guide rod 5.

[0056] In the above structure, by providing the cage 4, it facilitates the installation of the first guide rod 5 to connect the alignment plate 2, so that after the alignment plate 2 contacts the product surface, as the detection wire harness moves, the plug-in body 1 and the cage 4 can slide towards the alignment plate 2, enabling the connector 200 to be inserted into the electrical interface 101 of the plug-in body 1;

[0057] During the plugging process, the first spring 6 can play a buffering role to avoid plugging impact. At the same time, after the detection is completed, the first spring 6 is used for the self-resetting of the alignment plate 2.

[0058] As Figure 7 shown, the first guide rod 5 includes a threaded section 51, a connecting section 52 and a stop head 53 that are connected to each other. The diameters of the threaded section 51, the connecting section 52 and the stop head 53 increase in sequence. Among them, the threaded section 51 is threadedly connected to the alignment plate 2; the connecting section 52 is inserted into the cage 4; the stop head 53 is assembled in the cage 4 with a counterbore;

[0059] In the above structure, when connecting the alignment plate 2 and the cage 4, the first guide rod 5 is passed through the cage 4 and the first spring 6 in sequence, and then threadedly connected to the alignment plate 2. This makes the assembly have the advantages of convenient disassembly and assembly, which is beneficial to forming, disassembly and maintenance;

[0060] To ensure the regular and beautiful overall appearance, the stop head 53 is sunk into the cage 4.

[0061] As Figure 2 shown, the length of the part of the plug-in body 1 located between the cage 4 and the alignment plate 2 is less than the maximum extension length of the first spring 6;

[0062] In the above structure, by setting the length of the part of the plug-in body 1 located between the cage 4 and the alignment plate 2 to be less than the maximum extension length of the first spring 6, it makes the alignment plate 2 not contact the plug-in body 1 before detection, leaving space for the subsequent movement of the alignment plate 2, so that the alignment plate 2 can play a certain buffering effect during the detection plugging process and avoid plugging impact.

[0063] As Figure 2 shown, the bolt 7 passes through the cage 4 and is connected to the plug-in body 1. With such a structure, when connecting the cage 4 and the plug-in body 1, since the cage 4 is located outside the plug-in body 1, it can be serially fixed using fasteners such as bolts.

[0064] As Figure 2 shown, one end of the second guide rod 8 is fixedly connected to the plug-in body 1, and the other end passes through the bottom plate 3; the second spring 9 is sleeved on the second guide rod 8;

[0065] In the above structure, in some cases, it is necessary to first connect the plug-in body 1 to the connector 200 of the product, and then connect the connector of the detection wire harness to the plug-in body 1. Therefore, a second guide rod 8 and a second spring 9 are provided to buffer the insertion of the detection wire harness end. Especially for automated insertion equipment, the problem of insertion impact can be effectively avoided.

[0066] As Figure 3 shown, the plug-in body 1 includes a probe plug 11 and a profiling seat 12. Among them, the profiling seat 12 is arranged on the probe plug 11, and the probe of the probe plug 11 extends into the profiling seat 12; both the probe plug 11 and the profiling seat 12 are provided with electrical interfaces 101;

[0067] In the above structure, when integrating the plug-in body 1, relevant electrical components such as probes are integrated in the probe plug 11, and then the probe plug 11 is connected to the profiling seat 12 and the probe extends into the profiling seat 12. In this way, the probe plug 11 is used for electrical connection, and the profiling seat 12 is only used to limit the connector 200 at the product end;

[0068] Specifically, the probe plug 11 and the profiling seat 12 can be connected by bolts for easy disassembly and assembly. After a single component is damaged, it can be disassembled and replaced.

[0069] Specific implementation steps:

[0070] First, move the plug-in body 1 towards the product until the alignment plate 2 is docked to the connector 200. At this time, the connector 200 passes through the through hole 100 of the alignment plate 2, and then the alignment plate 2 abuts against the product. Under the guidance of the first guide rod 5, the cage 4 and the plug-in body 1 continue to move towards the product until the connector 200 of the product is inserted into the electrical interface 101 of the plug-in body 1. Then, the connector at the detection wire harness end is passed through the through hole 100 of the bottom plate 3 and connected to another electrical interface 101 of the plug-in body 1;

[0071] According to different application scenarios, the plug-in body 1 can also be first connected to the detection wire harness end and then to the product end.

[0072] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
