In the design process of the test fixture 10, if the auxiliary board 200 is directly connected to the main body, the auxiliary board 200 and the main body form a strong binding relationship, which inevitably causes the following defects:
firstly, when the software of the board 20 to be tested is changed or upgraded, the software of the auxiliary board 200 also needs to be changed or upgraded accordingly in order to ensure the testing accuracy. Generally, when the auxiliary board 200 is fixedly connected with the main body to form a binding relationship with strong dependence, it is difficult to change or upgrade the software of the auxiliary board 200 through the upper computer while the auxiliary board 200 and the main body are not detached. In such a situation, it is inevitable to forcibly detach the original auxiliary board 200 from the main body, and then change or upgrade the software of the auxiliary board 200 and then bind and install the auxiliary board 200 with the main body again. Or, the detached auxiliary board 200 is discarded, a new auxiliary board 200 that is matched with the board 20 to be tested after the software is changed or upgraded is additionally designed, and then the new auxiliary board 200 is bound with the body in a welding connection manner and is installed and connected. Therefore, when the old auxiliary board 200 is forcibly detached from the main body, the operation process is complicated, and the auxiliary board 200 is easily damaged, so that the test of the board 20 to be tested is delayed, thereby affecting the working efficiency of the test fixture 10. Meanwhile, when the auxiliary board 200 after software change or upgrade or the newly designed auxiliary board 200 is bound with the body again, the welding connection process is also complicated, and the work efficiency of the test fixture 10 is also affected by the test delay of the board 20 to be tested.
Secondly, when the material of the board 20 to be tested is changed, or the test items need to be added and modified, or the auxiliary board 200 itself has a hardware fault, the auxiliary board 200 needs to be replaced. During replacement, the original auxiliary single board 200 is first forcibly detached from the main body, and then the new auxiliary single board 200 is bound and installed on the main body again, similarly, the forcible detachment of the auxiliary single board 200 and the binding and installation of the new auxiliary single board 200 are both cumbersome, time and labor are wasted in the forcible detachment and binding installation, which results in that the test of the single board 20 to be tested cannot be performed in time and a certain delay exists, thereby affecting the working efficiency of the test fixture 10. And when the new auxiliary veneer 200 is connected with the body by welding, the new auxiliary veneer 200 may be damaged. When the new damaged auxiliary board 200 needs to be replaced again, the testing cost of the testing fixture 10 will be undoubtedly increased, and the testing of the board 20 to be tested is further delayed, which further affects the working efficiency of the testing fixture 10.
For the test fixture 10 of this embodiment, when the software of the board 20 to be tested is changed or upgraded, the upper computer may directly change or upgrade the software of the auxiliary board 200 connected to the adaptor 100, so as to be suitable for testing the board 20 to be tested after the software is changed or upgraded. Therefore, the auxiliary board 200 does not need to be disassembled and assembled, thereby saving the workload and the working time generated by disassembling and assembling, enabling the test fixture 10 to be suitable for testing the new board 20 to be tested in a short time, and further improving the working efficiency of the test fixture 10. Of course, the second thimble 220 of the auxiliary board 200 may also be directly pulled out from the jack of the adaptor 100, and then the pulled-out auxiliary board 200 is subjected to software change or upgrade and then inserted into the adaptor 100 again. Due to the simple plugging of the second thimble 220 relative to the jack, the auxiliary board 200 can be quickly mounted and dismounted on the adaptor 100, so that the replacement speed of the auxiliary board 200 is increased, the test of the board 20 to be tested is prevented from being delayed for a long time, and the test fixture 10 is ensured to have higher working efficiency. In addition, in the process of inserting and pulling the second thimble 220 into and out of the jack, the auxiliary board 200 can be effectively prevented from being damaged.
When the material of the board 20 to be tested is changed, or the test items need to be added and modified, or the auxiliary board 200 itself has a hardware fault, the auxiliary board 200 needs to be replaced. When replacing, the second thimble 220 is firstly pulled out from the jack, so that the auxiliary single board 200 is detached from the adaptor 100, and then the second thimble 220 of the new auxiliary single board 200 is directly inserted into the jack of the adaptor 100, so that the new auxiliary single board 200 is installed on the adaptor 100 to be suitable for the test of the single board 20 to be tested again. Similarly, due to the simple insertion and extraction of the second thimble 220 with respect to the jack, the auxiliary board 200 can be quickly mounted and dismounted on the adaptor 100, so as to increase the replacement speed of the auxiliary board 200, avoid the delay of the test of the board 20 to be tested due to the long waiting time, compress the replacement time of the auxiliary board 200 as much as possible, and increase the working efficiency of the test fixture 10 to the maximum extent. In addition, in the process of inserting and pulling the second thimble 220 into and out of the jack, the auxiliary board 200 can be effectively prevented from being damaged, so that the additional material cost caused by the damage of the auxiliary board 200 can be prevented, and the testing cost of the testing fixture 10 can be reduced to a certain extent.
Therefore, the test fixture 10 of this embodiment effectively eliminates the binding relationship between the auxiliary board 200 and the main body, prevents the forced detachment and welding connection generated during the replacement of the auxiliary board 200, greatly reduces the time and difficulty of detaching the auxiliary board 200, and also reduces the damage generated during the detaching process of the auxiliary board 200. When the board 20 to be tested next time is changed, the new board 20 to be tested can be adapted by plugging and pulling the new auxiliary board 200.
