[0002] When assembling multiple components, the first component is usually placed in the carrier first, followed by the second component, to complete the assembly of the two components. However, when assembling the third component with the second component, the assembly of the third component may fail because the first and second components lack positioning and clamping. Alternatively, the first component may detach during the assembly of the second and third components, leading to assembly failure and affecting assembly efficiency. Utility Model Content

[0027] In some embodiments of this application, a clamping fixture 100 is provided, as shown in the reference... Figures 1-9 The clamping fixture 100 includes: a base 10, a first push block 20, and a second push block 30.

[0028] Reference Figures 1-3 as well as Figures 7-9 The base 10 has three intersecting directions: a first direction X, a second direction Y, and a third direction Z, as shown in the details. Figures 1-8 In the embodiment shown, the first direction X, the second direction Y, and the third direction Z are all orthogonal to each other, specifically as follows: Figures 1-3 as well as Figures 7-9 In the embodiment shown, the base 10 is square in shape, with the first direction X parallel to the length direction of the base 10, the second direction Y parallel to the width direction of the base 10, and the third direction Z parallel to the height direction of the base 10. (Refer to...) Figure 4 The base 10 has a receiving cavity 101 extending through the base 10 in the first direction X. The base 10 has a bearing surface 102 intersecting the third direction Z. That is, the base 10 has two surfaces arranged opposite each other in the third direction Z, one of which is the bearing surface 102. (Refer to...) Figures 7-9 The bearing surface 102 is used to support the first component 200 and the second component 210, and the first component 200 and the second component 210 can be assembled on the bearing surface 102.

[0029] Reference Figures 1-2 as well as Figure 9 The first pusher block 20 is inserted into the receiving cavity 101, as shown in the reference. Figure 9 The first push block 20 can cooperate with the base 10 to clamp the first component 200.

[0030] Reference Figures 1-2 as well as Figures 7-8 The second pusher block 30 is inserted into the receiving cavity 101. The second pusher block 30 and the first pusher block 20 are stacked along the third direction Z, as shown in the reference. Figures 6-7 The second pusher 30 can cooperate with the base 10 to clamp the second component 210.

[0031] The first push block 20 can move along the first direction X, so that the first push block 20 can release or restore its clamping on the first component 200. Specifically, the first push block 20 can move forward or backward along the first direction X. The first push block 20 and the base 10 cooperate to form a clamping on the first component 200. Since the base 10 is fixed, the first push block 20 moves forward along the first direction X, the first push block 20 releases its clamping on the first component 200, the first push block 20 moves backward along the first direction X, and the first push block 20 restores its clamping on the first component 200.

[0032] The first push block 20 can drive the second push block 30 to move along the first direction X, so that the second push block 30 releases or restores its clamping on the second component 210. Specifically, the first push block 20 can drive the second push block 30 to move forward or backward along the first direction X. The second push block 30 cooperates with the base 10 to form a clamping on the second component 210. Since the base 10 is fixed, the second push block 30 moves forward along the first direction X, the second push block 30 releases its clamping on the second component 210, the second push block 30 moves backward along the first direction X, and the second push block 30 restores its clamping on the second component 210.

[0033] When assembling multiple components, the first component is typically placed in the carrier first, followed by the second, completing the assembly of those two components. However, when assembling the third component with the second, the lack of positioning and clamping between the already assembled first and second components can lead to assembly failure of the third component. Alternatively, the first component may detach during the assembly process, causing further assembly failure and impacting assembly efficiency. Even if existing carriers have clamping functions for the first and second components, these functions make it difficult to remove the assembled components from the carrier after assembly, and the presence of clamping functions poses a risk of components falling off the assembled parts.

[0034] Specifically, taking the assembly of automotive connectors as an example, multiple TPAs ​​(Terminal Position Assurances) need to be assembled on the HSG (housing) of an automotive connector. During assembly, the first TPA is usually placed in the carrier first, followed by the HSG, completing the assembly of the first TPA and HSG. When assembling the HSG with the second TPA, the lack of clamping and positioning for the HSG and the already assembled first TPA makes the assembly of the second TPA with the HSG prone to failure due to HSG shaking. Moreover, there is a possibility that the already assembled first TPA may fall off due to the shaking of the HSG, leading to assembly failure and affecting assembly efficiency. Even if the carrier is equipped with clamping and fixing components, it still makes the placement and removal of the HSG and the first TPA inconvenient, affecting assembly efficiency and assembly success rate.

[0035] The clamping fixture 100 provided in this application embodiment has a receiving cavity 101 extending through the base 10 in a first direction X. The base 10 has a bearing surface 102 for supporting a first component 200 and a second component 210. The first component 200 and the second component 210 can be assembled on the bearing surface 102. A first push block 20 is inserted into the receiving cavity 101, and one end of the first push block 20 in the first direction X can cooperate with the base 10 to clamp the first component 200. A second push block 30 is inserted into the receiving cavity 101, and the second push block 30 and the first push block 20 are stacked in a third direction Z. One end of the second push block 30 in the first direction X can cooperate with the base 10 to clamp the second component 210. This ensures the stability of the first component 200 during assembly with the third component 220 and the first component 200, as well as the stability between the first component 200 and the assembled second component 210, thus guaranteeing assembly efficiency and success rate. Furthermore, the first push block 20 can move along the first direction X, allowing it to release or restore its grip on the first component 200, facilitating the placement and removal of the first component 200 on the bearing surface 102. The first push block 20 can also drive the second push block 30 to move along the first direction X, allowing it to release or restore its grip on the second component 210, thereby facilitating the placement and removal of the second component 210 on the bearing surface 102, improving assembly convenience and efficiency.

[0036] In some embodiments, the first component 200 can be an HSG in an automotive connector, the second component 210 can be a TPA, and the third component 220 can be a TPA, thereby ensuring the assembly efficiency and assembly success rate between the HSG and multiple TPAs ​​through the clamping fixture 100 provided in this application embodiment.

[0037] In some embodiments, refer to Figures 2-3 as well as Figures 5-6 One of the first push block 20 and the second push block 30 has a protruding insertion part 31, and the other has an insertion hole 21. The insertion hole 21 has a hole wall 211 surrounding the insertion hole 21 in the circumferential direction. The insertion part 31 is inserted into the insertion hole 21 and can move in the insertion hole 21 along the first direction X. That is, the insertion hole 21 is a strip hole, and the insertion part 31 can move forward or backward in the insertion hole 21 along the first direction X. The first push block 20 moves along the first direction X until the insertion part 31 abuts against the hole wall 211. The first push block 20 drives the second push block 30 to move along the first direction X. Specifically, the first push block 20 moves forward along the first direction X until the insertion part 31 abuts against one end of the hole wall 211 along the first direction X. Next, the first push block 20 drives the second push block 30 to move forward along the first direction X. The first push block 20 then moves backward along the first direction X until the insertion part 31 abuts against the other end of the hole wall 211 along the first direction X. The first push block 20 then drives the second push block 30 to move backward along the first direction X. Thus, after the first push block 20 moves a certain distance along the first direction X, it drives the second push block 30 to move along the first direction X. Therefore, the first push block 20 can be clamped or released by moving alone, and the first push block 20 and the second push block 30 can be clamped or released by moving together. This allows the operator to choose which part to use, making assembly more flexible and improving assembly efficiency.

[0038] In some embodiments, refer to Figure 3 and Figure 5 The first push block 20 has a first receiving groove 201 on the side facing the bearing surface 102 along the third direction Z. The first receiving groove 201 extends through the first push block 20 along the first direction X to form a through groove structure. The first receiving groove 201 includes two groove walls 202 arranged opposite each other along the second direction Y. The insertion hole 21 is formed on the groove wall 202, specifically as follows: Figure 5 In the embodiment shown, two slot walls 202 are respectively provided with insertion holes 21, and the insertion holes 21 penetrate the slot walls 202 along the second direction Y, as shown in the figure. Figure 3 and Figure 6 The second push block 30 is embedded in the first receiving groove 201, and the insertion part 31 protrudes from the second push block 30, as shown in the following figure. Figure 6 In the embodiment shown, the plug-in part 31 is in the shape of a rod. The plug-in part 31 passes through the second push block 30 along the second direction Y. The two opposite ends of the plug-in part 31 along the second direction Y are respectively inserted into the adjacent plug holes 21. The first push block 20 moves along the first direction X until the hole wall 211 of the plug hole 21 abuts against the plug-in part 31, thereby driving the second push block 30 to move along the first direction X.

[0039] In some embodiments, the insertion hole 21 is formed on the second push block 30, and the insertion hole 21 passes through the second push block 30 along the second direction Y to form a through hole structure, or the insertion hole 21 is a slot structure. The insertion part 31 is disposed on the first push block 20 and inserted into the insertion hole 21. The first push block 20 drives the insertion part 31 to move along the first direction X until the insertion part 31 abuts against one end of the hole wall 211 of the insertion hole 21 along the first direction X, so as to drive the second push block 30 to move along the first direction X.

[0040] In some embodiments, refer to Figures 1-2 , Figure 4 , Figure 7 as well as Figure 9 The base 10 includes a first end 11 and a second end 12 disposed opposite to each other along the first direction X. A first protrusion 1021 is provided on the bearing surface 102 protruding from the end adjacent to the first end 11 along the first direction X. (Refer to...) Figures 1-3 , Figure 5 as well as Figure 7 and Figure 9 The first push block 20 has a second protrusion 22 protruding from one end of the second end 12 along the first direction X. Part of the second protrusion 22 extends along the third direction Z to the top of the bearing surface 102. The second protrusion 22 and the first protrusion 1021 are spaced apart along the first direction X. The first protrusion 1021 and the second protrusion 22 cooperate to clamp the first component 200, so that the first component 200 can be stably placed on the bearing surface 102, ensuring the smooth progress of subsequent assembly. The first push block 20 moves along the first direction X, and the second protrusion 22 moves away from the first protrusion 1021 along the first direction X to release the clamping of the first component 200, so as to facilitate placing the first component 200 on the bearing surface 102 or removing the first component 200 from the bearing surface 102.

[0041] In some embodiments, refer to Figure 4 A third receiving groove 121 is provided on the end face of the second end 12 of the base 10. The third receiving groove 121 extends along the first direction X and communicates with the receiving cavity 101. The third receiving groove 121 has a first bottom wall 1211. A second protrusion 22 is inserted into the third receiving groove 121 and abuts against the first bottom wall 1211. The second protrusion 22 can move along the first direction X in the third receiving groove 121, so that the second protrusion 22 and the first protrusion 1021 cooperate to clamp or release the first component 200.

[0042] In some embodiments, refer to Figures 1-2 , Figure 4 , Figure 7 as well as Figure 9There are two first protrusions 1021, which are spaced apart along the second direction Y. One first protrusion 1021 is bent at one end away from the other first protrusion 1021 along the second direction Y to form a bent portion 1022. The bent portion 1022 extends along the first direction X. The two bent portions 1022 cooperate to limit the first component 200 along the second direction Y. The setting of the bent portion 1022 makes the first protrusion 1021 L-shaped and set on the bearing surface 102. While the first protrusion 1021 cooperates with the second protrusion 22 to clamp the first component 200 along the first direction X, the bent portion 1022 can also limit the first component 200 along the second direction Y, so as to prevent the first component 200 from shaking during the assembly process, ensure the smooth assembly, and improve the assembly efficiency.

[0043] In some embodiments, refer to Figures 1-2 , Figure 4 as well as Figures 7-8 A second receiving groove 13 for accommodating the second component 210 is provided on the bearing surface 102. Specifically, the second receiving groove 13 is provided at the end of the bearing surface 102 away from the first protrusion 1021 along the first direction X. The end of the second receiving groove 13 adjacent to the second end 12 along the first direction X passes through the second end 12. The second receiving groove 13 has a groove bottom 131. (Refer to...) Figure 7 and Figure 8 The second component 210 is embedded in the second receiving groove 13. (Refer to...) Figures 1-3 as well as Figures 6-8 The second push block 30 has a third protrusion 32 protruding from one end of the second end 12 along the first direction X. Part of the third protrusion 32 extends along the third direction Z to the top of the bearing surface 102. The third protrusion 32 cooperates with the bottom of the groove 131 to form a clamping grip on the second component 210. The first push block 20 drives the second push block 30 to move along the first direction X. The third protrusion 32 moves away from the bottom of the groove 131 to release the clamping grip on the second component 210, so that the second component 210 can be placed in the second receiving groove 13 or removed from the second receiving groove 13.

[0044] In some embodiments, refer to Figures 1-2 as well as Figure 4A fourth receiving groove 122 is provided on the first bottom wall 1211 of the third receiving groove 121. The fourth receiving groove 122 extends along the first direction X and communicates with the receiving cavity 101. The fourth receiving groove 122 has a second bottom wall 1221. A third protrusion 32 is inserted into the fourth receiving groove 122 and abuts against the second bottom wall 1221. The third protrusion 32 can move along the first direction X in the fourth receiving groove 122 and the third receiving groove 121, so that the third protrusion 32 cooperates with the bottom 131 of the second receiving groove 13 to clamp or release the second component 210.

[0045] In some embodiments, refer to Figure 4 The bearing surface 102 is provided with a through hole 1023 that communicates with the receiving cavity 101. Specifically, the third receiving groove 121 and the fourth receiving groove 122 are respectively connected to the receiving cavity 101 through the through hole 1023. The opening of the through hole 1023 makes the distance between the third protrusion 32 and the groove bottom 131 along the first direction X adjustable, thereby adapting to the second component 210 of different lengths and improving the space utilization in the first direction X, making the overall structure of the clamping carrier compact.

[0046] In some embodiments, refer to Figures 1-2 , Figure 7 and Figure 9The clamping fixture 100 also includes a first elastic member 40 and a support portion 14. The support portion 14 is disposed on the side of the second end 12 of the base 10 away from the first end 11 along the first direction X. The first elastic member 40 extends along the first direction X, with one end connected to the support portion 14 and the other end connected to a first push block 20. The first push block 20 can move along the first direction X toward the support portion 14 and squeeze the first elastic member 40, thereby releasing the clamping of the first component 200 by the first push block 20. Specifically, the first push block 20 squeezes the first elastic member 40, and the second protrusion 22 moves away from the first protrusion 1021 along the first direction X, thereby releasing the clamping of the first component 200. The clamping of component 200 involves the first elastic member 40 pushing the first push block 20, causing the first push block 20 to move away from the support portion 14 along the first direction X, until the first push block 20 cooperates with the base 10 to clamp the first component 200. Specifically, the first elastic member 40 pushes the first push block 20 by its own elastic deformation, causing the second protrusion 22 to move along the first direction X toward the first protrusion 1021, until the second protrusion 22 abuts against the second end 12 of the base 10. Specifically, the second protrusion 22 is embedded in the third receiving groove 121 opened at the second end 12, and the second protrusion 22 and the first protrusion 1021 cooperate to form a clamping of the first component 200. The cooperative design of the first elastic element 40 and the support portion 14 provides power for the first push block 20 to move along the first direction X. This allows the first push block 20 to regain its grip on the first component 200 after it releases its grip, through the elastic deformation of the first elastic element 40. This improves the automation level of the clamping fixture 100 and increases assembly efficiency. Furthermore, the pushing action of the first elastic element 40 on the first push block 20 ensures that the second protrusion 22 maintains its grip on the first component 200, preventing the first component 200 from loosening during assembly and ensuring assembly success rate and efficiency.

[0047] In some embodiments, refer to Figures 1-2 as well as Figures 7-8The clamping fixture 100 also includes a second elastic member 50, which extends along a first direction X. One end of the second elastic member 50 is connected to the support portion 14, and the other end is connected to the second push block 30. The first push block 20 can drive the second push block 30 to move along the first direction X toward the support portion 14, so that the second push block 30 squeezes the second elastic member 50, and the second push block 30 releases the clamping of the second component 210. Specifically, the second push block 30 squeezes the second elastic member 50, and the third protrusion 32 moves away from the bottom 131 of the second receiving groove 13 along the first direction X, so as to release the clamping of the second component 210. The second elastic member 50 pushes the second elastic member 50. The second push block 30 moves away from the support part 14 along the first direction X until the second push block 30 cooperates with the base 10 to clamp the second component 210. Specifically, the second elastic member 50 pushes the second push block 30 by its own elastic deformation, causing the third protrusion 32 to move along the first direction X toward the bottom of the groove 131 until the third protrusion 32 abuts against the second end 12 of the base 10. Specifically, the third protrusion 32 enters the fourth receiving groove 122 through the third receiving groove 121 and abuts against the second bottom wall 1221, so that the third protrusion 32 cooperates with the bottom 131 of the second receiving groove 13 to clamp the second component 210. The design of the second elastic element 50 and the support portion 14 provides power for the second push block 30 to move along the first direction X. This allows the second push block 30 to regain its grip on the second component 210 after it releases its grip, through the elastic deformation of the second elastic element 50. This improves the automation level of the clamping fixture 100 and increases assembly efficiency. Furthermore, the pushing action of the second elastic element 50 on the second push block 30 ensures that the third protrusion 32 maintains its grip on the second component 210, preventing the second component 210 from loosening during assembly and ensuring assembly success rate and efficiency.

[0048] In some embodiments, refer to Figure 2 The second elastic element 50 is inserted into the first elastic element 40, and the second elastic element 50 is coaxial with the first elastic element 40, thereby improving the space utilization of the clamping fixture 100 in the third direction Z, making the overall structure compact.

[0049] In some embodiments, refer to Figures 1-2 , Figure 7 as well as Figure 9 The end of the support part 14 facing away from the bearing surface 102 along the third direction Z is connected to the base 10 through the connecting part 15, thereby ensuring the stability of the support part 14 and ensuring the stable support of the support part 14 for the first elastic member 40 and the second elastic member 50.

[0050] In some embodiments, refer to Figures 1-2 , Figure 4 , Figure 7 as well as Figure 9The base 10 has a mounting part 16 at one end opposite to the support part 14 along the first direction X. The mounting part 16 extends along the first direction and has a mounting hole 161 to facilitate the installation and fixation of the clamping fixture 100.

[0051] In some embodiments, refer to Figure 6 The second push block 30 has an insertion hole 301 at one end adjacent to the support part 14 along the first direction X. The end of the second elastic member 50 away from the support part 14 is inserted into the insertion hole 301 to ensure the connection stability between the second elastic member 50 and the second push block 30.

[0052] Taking the assembly of HSG and TPA in automotive connectors as an example, combined with Figures 1-9 The following describes the usage of the clamping fixture 100 provided in the embodiments of this application:
