Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0029] Please see Figure 1 and Figure 2 , Figure 1 This is a three-dimensional structural schematic diagram of the test module 100 according to one embodiment of the present utility model; Figure 2 yes Figure 1 A cross-sectional view of the test module 100 through the snap hole 1201 is shown in the figure. This invention provides a test module 100, which includes a mounting mechanism 10 and a test connector 20. The mounting mechanism 10 includes a mounting block 11, a connecting structure 12, and a first elastic member 13. The mounting block 11 and the connecting structure 12 are slidably connected relative to each other. The first elastic member 13 is in a compressed state, and its two ends are respectively connected to the mounting block 11 and the connecting structure 12. The connecting structure 12 has a snap hole 1201. The test connector 20 includes a test body 21 and a snap-fit ​​block 22. One end of the snap-fit ​​block 22 is connected to the test body 21, which is used for electrical connection with signal lines and test products. When the test body 21 passes through the connecting structure 12 and the mounting block 11 in sequence, the connecting structure 12 compresses the snap-fit ​​block 22, causing the other end of the snap-fit ​​block 22 to deform close to the test body 21 and engage with the snap hole 1201. When the other end of the fastening block 22 is subjected to force to deform close to the test body 21, the fastening block 22 can disengage from the fastening hole 1201.

[0030] Specifically, the first elastic element 13 is a spring, and the extension direction of the spring is parallel to the relative sliding direction of the mounting block 11 and the connecting structure 12. It can be understood that the presence of the first elastic element 13 provides cushioning for the test product, preventing it from being damaged by impact.

[0031] By opening a snap hole 1201 on the mounting block 11 and setting a snap block 22 on the connecting structure 12, the tester can quickly install the test connector 20 by pushing and inserting the test body 21, and quickly disassemble the test connector 20 by pressing the snap block 22. The disassembly and assembly of the test connector 20 is relatively simple, which reduces the replacement time of the test connector 20 and improves the testing efficiency.

[0032] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The test body 21 includes a first test head 211, a connecting plate 212, and a second test head 213. One end of the connecting plate 212 passes through the mounting block 11 and is connected to the first test head 211. The other end of the connecting plate 212 passes through the connecting structure 12 and is connected to the second test head 213. One of the first test head 211 and the second test head 213 is used for electrical connection with a signal line, and the other is used for electrical connection with the test product. A fastening block 22 is disposed on the second test head 213. Specifically, the first test head 211 extends relative to the mounting block 11, and the second test head 213 extends relative to the connecting structure 12 to facilitate electrical connection with the signal line and the test product, respectively. With this configuration, the signal line and the test product can be electrically connected through the test body 21 to provide the electrical signals required for testing the test product.

[0033] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The fastening block 22 includes a connecting portion 221 and a fastening portion 222. The connecting portion 221 is elastic and connects the second test head 213 and the fastening portion 222. The fastening portion 222 and the second test head 213 are spaced apart. This arrangement, with the fastening portion 222 spaced apart from the second test head 213, provides movement space for the fastening portion 222. Simultaneously, the elasticity of the connecting portion 221 allows it to deform elastically under the pressure of the connecting structure 12, causing the fastening portion 222 to move towards the second test head 213. Furthermore, the elasticity of the connecting portion 221 allows the fastening portion 222 to engage within the fastening hole 1201 through restoring deformation, thus achieving rapid installation.

[0034] In one embodiment of this implementation, please refer to Figure 1 and Figure 2The direction in which the mounting block 11 slides relative to the connecting structure 12 is defined as the first direction 91. The connecting portion 221 is bent. A part of the connecting portion 221 is connected to the side of the second test head 213 facing the mounting block 11 and extends along the first direction 91. The other part of the connecting portion 221 extends along a second direction 92 perpendicular to the first direction 91 and is connected to the fastening portion 222. This arrangement allows the connecting portion 221 to undergo sufficient elastic deformation.

[0035] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The fastening part 222 has a first protrusion 2221 on the side facing away from the second test head 213. The first protrusion 2221 can be engaged with the fastening hole 1201. The side of the first protrusion 2221 facing the mounting block 11 has an inclined surface 22211. It can be understood that during the installation process, the connecting structure 12 can slide along the inclined surface 22211 to compress the fastening part 222, causing the connecting part 221 to undergo elastic deformation, driving the fastening part 222 towards the second test head 213, so as to realize the quick installation of the test connector 20.

[0036] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The fastening block 22 has a second protrusion 2222 on the side facing away from the second test head 213. The second protrusion 2222 and the first protrusion 2221 are spaced apart and together clamp the connecting structure 12. This arrangement allows the test connector 20 to be securely installed with the connecting structure 12.

[0037] In one embodiment of this implementation, please refer to Figure 1 and Figure 3 , Figure 3 yes Figure 1 The diagram shows a cross-sectional view of the test module 100 through the connecting column 124. The connecting structure 12 includes a first floating block 121, a second floating block 122, and a second elastic member 123. The first floating block 121 is fixedly connected to the first elastic member 13 and connected to the second floating block 122 through the second elastic member 123. A snap-fit ​​hole 1201 is formed in the second floating block 122. This arrangement, in conjunction with the first elastic member 13, provides two levels of cushioning for the test product, further reducing the risk of the test product being damaged by impact.

[0038] In one embodiment of this implementation, please refer to Figure 1 and Figure 3The connecting structure 12 includes a connecting post 124, a second elastic element 123 sleeved on the connecting post 124, one end of the connecting post 124 fixed to a second floating block 122, and the other end of the connecting post 124 engaging with the conical surface of a first floating block 121, so that the first floating block 121 and the second floating block 122 can move relative to each other along a deformation direction perpendicular to the second elastic element 123. With this configuration, the second floating block 122 can drive the second test head 213 to move relative to the first floating block 121 along a deformation direction perpendicular to the second elastic element 123, facilitating smooth insertion of the test product and reducing the risk of damage to the test product. Furthermore, under the elastic action of the second elastic element 123, the second floating block 122 can reset after the test product is inserted, which helps improve the reliability of the test.

[0039] In this embodiment, the insertion direction of the test product is parallel to the first direction 91, and the deformation direction of the second elastic element 123 is parallel to the first direction 91.

[0040] In one embodiment of this implementation, please refer to Figure 1 and Figure 3 The mounting mechanism 10 includes a guide post 14, one end of which is fixedly connected to the first floating block 121, and the other end of which is slidably connected to the mounting block 11. The guide post 14 and the first elastic element 13 are arranged in parallel. This arrangement separates the guide post 14 and the first elastic element 13, saving space.

[0041] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 The second floating block 122 has a mounting hole 12201, and the test body 21 is housed in the mounting hole 12201. Specifically, the second test head 213 is housed in the mounting hole 12201. This arrangement allows the test connector 20 to be securely installed with the connection structure 12.

[0042] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
