[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1As shown in Example 1, a multi-dimensional movable structure for correcting connector docking deviation is designed to address the problem of unstable docking of automated testing equipment fixtures during use. The structure primarily includes a connector body 1, which is floatingly mounted within a frame 3 via a front baffle 2, ensuring that the connector body can move within a small range within the frame. Elastic support members 8 are provided on the surfaces of the connector body 1 corresponding to the front baffle 2 and the frame 3. Specifically, elastic support members are provided on both the surfaces of the connector body corresponding to the front baffle and the surface of the connector body corresponding to the frame. These elastic support members increase the connector body's degree of freedom, effectively compensating for connector docking deviation and improving test consistency, stability, and reliability.

[0030] like Figure 2 As shown in Example 2, a multi-dimensional movable structure for correcting connector docking deviation is provided. Based on Example 1, in this embodiment, as a preferred solution, the frame 3 is a hollow structure. The front baffle 2 and the frame 3 are fixed to form a movable cavity that matches the connector body 1. The connector body 1 is placed between the frame 3 and the front baffle 2, so that the connector body 1 can achieve a floating centering effect between the frame 3 and the front baffle 2. An elastic support member 8 is embedded on the outer surface of the connector body 1 located within the movable cavity. That is, the connector body 1 is not directly connected to the frame, and a movable cavity is reserved, allowing the main structure to move in multiple dimensions within the cavity. At the same time, the elastic support member 8 is used to ensure that the connector body can be quickly and effectively connected to the detection component.

[0031] On the basis of the above embodiment, as a preferred embodiment, the connector body 1 is a boss structure, and the boss structure includes a large head and a small head. After the front baffle 2 is fixed to the frame 3, the boss part of the connector body 1, that is, the large head, is located in the movable cavity and is axially limited by the front baffle 2. In order to stabilize the connector body 1, the front baffle 2 limits the axial movement of the connector body 1.

[0032] On the basis of the above embodiment, as a preferred embodiment, a connecting hole I4 is provided on the upper end face of the frame 3, and a connecting hole II5 is provided on the front baffle 2. The connecting hole I4 corresponds to the connecting hole II5 and is connected by bolts to realize the detachable connection between the front baffle and the frame, and at the same time facilitates the express positioning of the connector body. A plug-in hole 6 communicating with the movable cavity is provided on the lower end face of the frame, and the setting of the plug-in hole facilitates the passage of the wiring harness.

[0033] like Figure 3 As shown, Example 3 is a multi-dimensional movable structure for correcting connector docking deviation. On the basis of Example 1 or 2, in this embodiment, the left and right ends of the front baffle 2 extend out of the frame 3 respectively, and the protruding part is provided with a fixing hole 7. This structural assembly can be made into a separate module and connected to the clamp pushing mechanism assembly, which is convenient for subsequent maintenance and product connector modification.

[0034] As a preferred embodiment, the connector body 1 is a square or rectangular boss structure; the corresponding front baffle 2 is a rectangular plate, and the frame 3 is a square or rectangular frame. It should be noted that in actual production, the connector body 1 can also be a cylindrical boss or other structure as needed, and the corresponding front baffle 2 and frame 3 are also designed to match.

[0035] In this embodiment, at least two elastic support members 8 are provided on the surfaces of the connector body 1 corresponding to the front baffle 2 and the frame 3 to prevent jamming caused by an excessive span. The elastic support members are embedded in the body. Taking the connector body 1 as an example, with a rectangular boss structure, corresponding surfaces are formed on the two surfaces (left and right) between the boss surface of the connector body 1 and the bottom surface of the front baffle 2, between the four outer surfaces of the connector body 1 and the inner side surface of the frame, and between the bottom surface of the connector body 1 and the bottom side surface of the frame. At least two elastic support members are provided between each pair of corresponding surfaces to prevent jamming or blocking of the elastic support members while ensuring the flexibility of the connector body.

[0036] like Figure 4 As shown, in this embodiment, as a preferred solution, the elastic support member 8 may include a columnar body 81, and a spherical body 82 is hinged on the top of the columnar body. The spherical body 82 is embedded in the top of the columnar body 81 in the form of a ball hinge, and the bottom of the columnar body is plugged into the hole set on the connector body 1. The columnar body can rotate in the corresponding hole, and at the same time, the ball state can rotate relative to the columnar body, thereby improving its degree of freedom and ensuring its flexibility. When docking with the detection part, it can realize relative spatial movement according to the position of the connector of the tested product to ensure that the required connection angle and size are achieved with the connector, and the connection effect is stable.

[0037] Example 4, as Figure 5 As shown, the difference between this embodiment and embodiment 3 is that the elastic support member 8 described in this embodiment includes a support column 8-1, the bottom of the support column 8-1 is connected to the hole on the connector body 1 through a spring 8-2, the support column is plugged into the hole on the connector body 1, and the top of the support column 8-1 is a hemisphere, which can be fixedly connected to the support column or can be designed as an integral molding or a ball joint connection design to ensure floating support for the connector body.

[0038] Example 5, as Figure 6As shown, the difference between this embodiment and embodiment 3 is that the elastic support member 8 in this embodiment includes a spherical body 8a and a pillar body 8b. The spherical body 8a is located in a circular hole provided on the connector body 1, and forms a ball hinge connection with the connector body 1. The pillar body 8b is fixed on the spherical body 8a and extends outward from the connector body 1. The top surface of the pillar body 8b can be designed to be a corresponding arc or hemispherical shape. The elastic support member in this embodiment can also ensure floating support for the connector body.

[0039] Example 6, as Figure 7 As shown, a multi-dimensional movable structure for correcting connector docking misalignment is described. Based on Examples 3, 4, or 5, the elastic support member 8 can also utilize other structural members with floating or elastic supports. In this embodiment, the connector body 1 can be designed as a dedicated connector block that can directly dock with the product connector. When the fixture docks with the product, this mechanism can move relative to the position of the tested product connector in space to ensure the required connection angle and dimension, stabilize the connection, and improve test consistency, stability, and reliability.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
