[0029] In view of the deficiencies in the prior art, the inventor of this case has proposed the technical solution of the utility model after long-term research and extensive practice. The technical solution, its implementation process and principle will be further explained as follows.

[0030] The present utility model embodiment provides an auxiliary testing device for high-density connectors, such as Figure 1 As shown, the auxiliary testing device for high-density connectors includes a base 1, a sample holder 2, a fixing holder 4 and a transmission structure 3.

[0031] A guide structure extending in a selected direction is provided on the working surface of the base 1; specifically, the guide structure includes a guide rail 5 and a slider 6 movably matched with the guide rail, the guide rail is fixedly provided on the working surface of the base 1, and the sample holder 2 is fixedly connected to the slider 6. Preferably, a guide groove is provided on the working surface of the base 1, and the guide rail is provided in the guide groove. The slider 6 drives the sample holder 2 to move along the guide rail 5 to ensure that the sample holder 2 moves in a straight line, and prevents the sample holder 2 from swinging while moving horizontally, thereby causing the connector pin to be unable to be accurately inserted into the mating end.

[0032] The sample holder 2 is used to carry the connector to be tested. The connector is the product to be tested in the utility model. During the test, the pin of the connector is inserted into the mating end and tested. The sample holder 2 is arranged on the working surface of the base 1. The sample holder 2 is movably matched with the guide structure and can move along the track defined by the guide structure so that the connector pin and the mating end are in the same plane, avoiding the pin from tilting relative to the mating end and causing distortion, thereby affecting product quality. At the same time, the connector pin and the mating end are in the same plane so that the connector pin can be inserted into the mating end in a straight line, thereby improving test efficiency. Figure 2 As shown, the sample holder 2 has a bearing table, and a plurality of limit blocks 22 are fixedly arranged on the bearing table, and the plurality of limit blocks 22 enclose a fixed space that matches the shape of the connector. Specifically, the side of the limit block 22 facing the fixed space is an inclined slope. The utility model fixes the connector in a space enclosed by a plurality of limit blocks 22. Compared with other fixing methods (such as fixing by screws and fixing plates), this fixing method is simple to operate, saves time in fixing the connector, and improves test efficiency.

[0033] More specifically, the plurality of limit blocks 22 include a first limit block, a second limit block and a third limit block, the first limit block and the second limit block are located on the same side of the bearing table, the first limit block and the second limit block are spaced apart along the first direction, the third limit block is spaced apart and relatively arranged with the first limit block and the second limit block along the second direction, the width of the third limit block in the second direction is the same as the width of the bearing table, the first limit block has a first guide surface, the second limit block has a second guide surface, the third limit block has a third guide surface, the first guide surface and the second guide surface are relatively arranged and are inclined in directions tending to each other, the third guide surface faces the first limit block and the second limit block, and the third guide surface as a whole is arranged at an angle to the first direction or the second direction, wherein the first direction and the second direction intersect vertically.

[0034] The fixing seat 4 is used to fix the mating end of the test device. The fixing seat 4 is fixedly arranged on the base 1, and the fixing seat 4 is arranged on the first side of the sample holder 2 along the selected direction. Specifically, the fixing seat 4 has a through positioning hole 41, and the positioning hole 41 allows the mating end of the test device to extend into or pass through, and the positioning hole 41 faces the sample holder 2. The mating end of the test device is fixed in the positioning hole 41, so that the mating end of the test device is in a fixed position. The width of the positioning hole 41 in the first direction is smaller than the spacing between the first limit block and the second limit block.

[0035] The transmission structure 3 is fixedly arranged on the working surface of the base 1 and is located at the second side of the sample holder 2. The transmission structure 3 is connected to the sample holder 2 and can convert the external force applied to itself into a driving force to drive the sample holder 2 to move along the guide structure. Figure 4 As shown, the transmission structure 3 includes a base 31, a guide rod 32, a connecting rod and a handle 33. The base 31 is fixed on the work surface of the base 1. The base 31 is provided with a guide hole. The guide rod 32 movably passes through the guide hole. One end of the guide rod 32 is fixedly connected to the sample holder 2, and the other end is pivotally connected to the handle 33 via the connecting rod. The handle 33 is also pivotally connected to the base 31. When the handle 33 is driven to rotate relative to the base 31, the guide rod 32 can be driven to make a linear motion along the guide hole. Figure 4As shown, when the handle 33 is pulled upward, the guide rod 32 moves toward the direction close to the fixed seat 4, thereby driving the connector pin to move toward the direction close to the mating end, and then the pin is inserted into the mating end; when the handle 33 is pulled downward, the guide rod 32 moves away from the fixed seat 4, thereby driving the connector pin to move away from the mating end, and then the connector pin is pulled out from the mating end. The utility model uses the handle 33 to drive the sample holder 2 to move forward and backward, and the speed of driving the sample holder 2 forward or backward can be artificially controlled according to the situation. At the same time, since the pins are numerous and relatively soft, if the speed of driving the sample holder 2 is fast, the pins may be twisted and deformed.

[0036] In some embodiments, Figure 2 As shown, the base 1 is provided with a connecting hole 7, through which the base 1 can be fixed on the work surface. The connecting hole 7 can be a pin hole, and the pin is inserted into the pin hole to fix the base 1 on the work surface. The connecting hole 7 can also be a threaded hole, and the screw and the threaded hole are threadedly connected to fix the base 1 on the work platform.

[0037] It should be understood that the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
