Description

Technical Field

[0001] This utility model relates to the field of link testing fixture technology, and in particular to a single-board link testing fixture. Background Technology

[0002] Single-board link testing is a key technical step in the research, development, production, and maintenance of electronic equipment. It is mainly used to verify the integrity and reliability of high-speed signal links on a single circuit board (single board).

[0003] In the existing technology, single-board link test fixtures are usually dedicated fixtures designed for specific machine models. They cannot be changed to other machine models for testing, nor can they be reused in whole or in part on other machine models. As a result, different machine models need to be made with separate dedicated single-board link test fixtures for testing. In particular, the cost of the test probe mold is high, resulting in a large overall investment cost for the fixture.

[0004] In addition, in the single-board link test fixture, the test probe mold is usually installed and locked on the mounting plate by equal-height screws. The cable at the tail of the test probe mold passes through the through slot in the middle of the mounting plate and enters the electrical cabinet. When the test probe mold needs to be disassembled for maintenance or other reasons, tools are needed to unscrew the equal-height screws and remove the test probe mold. However, at this time, due to the limited space, disassembly and assembly are often very inconvenient. Utility Model Content

[0005] This utility model provides a single-board link test fixture to solve at least one of the problems in the prior art, such as the inability to reuse multiple machine models and the difficulty in disassembling the pin mold.

[0006] According to one aspect of the present invention, a single-board link test fixture is provided, including a base, on which a product positioning component and a pin mold mounting component are provided. The product positioning component is used to install the product to be tested. The base is provided with a pin mold mounting pin hole. The pin mold mounting component is provided with a pin mold positioning pin hole corresponding to the pin mold mounting pin hole. The pin mold mounting component is detachably provided with a pin mold component.

[0007] The single-board link test fixture of this utility model detachably installs the pin mold onto the pin mold mounting assembly. The pin mold mounting assembly and the base are provided with pin mold mounting pin holes and pin mold positioning pin holes. Thus, the installation and removal of the pin mold mounting assembly on the base can be completed simply by inserting and removing the pins, realizing the function of simple and quick installation and removal of the pin mold assembly.

[0008] In some embodiments, the needle mold mounting assembly includes a needle mold base plate and a slot disposed on the needle mold base plate, and the bottom of the needle mold assembly is provided with a boss that matches the slot.

[0009] Therefore, by using this configuration, the engagement between the boss and the slot can be used to quickly install the needle mold assembly onto the needle mold mounting assembly, thus enabling simpler and faster installation and removal of the needle mold.

[0010] In some embodiments, a spring plunger structure is provided on one side of the boss, and a positioning hole adapted to the spring plunger structure is provided on the slot, the positioning hole penetrating the needle die base plate.

[0011] Therefore, by using this design, the spring plunger structure and the positioning hole work together to ensure that after the boss on the needle mold assembly is inserted into the groove, the spring plunger structure automatically engages with the positioning hole, preventing the needle mold from easily detaching and improving the structural connection stability during testing. When it is necessary to disassemble the needle mold assembly, simply press the spring plunger structure from one side of the positioning hole to retract it, disengaging it from the positioning hole, allowing the needle mold assembly to be easily removed. The entire process is simple and quick.

[0012] In some embodiments, the needle mold mounting assembly is further provided with a limiting platform for abutting against the side of the needle mold assembly.

[0013] Therefore, by setting it up in this way, the pin mold assembly can be supported by the limiting platform, thereby improving the structural connection stability of the pin mold assembly when the fixture is being tested.

[0014] In some embodiments, the needle mold assembly includes a housing and a needle, the needle being disposed on one side of the housing, and the limiting platform being configured to abut against a side of the housing of the needle mold assembly opposite to the side where the needle is disposed.

[0015] Since the connector needs to be inserted into the needle on the needle mold assembly during testing, the limiting platform can be set on the side of the needle mold assembly opposite to the side with the needle, thereby effectively supporting the needle and improving the structural connection stability of the needle mold assembly during use.

[0016] In some embodiments, the plane height on which the needle mold assembly is not mounted on the needle mold base plate is lower than the plane height on which the needle mold assembly is mounted on the needle mold base plate.

[0017] Therefore, this design effectively reduces the thickness of the needle mold base plate, thereby lowering costs.

[0018] In some embodiments, the base is provided with a needle mold mounting positioning post, and the needle mold base plate is provided with a needle mold mounting hole corresponding to the needle mold mounting positioning post.

[0019] Therefore, this design allows for the initial positioning of the needle mold base plate during installation, utilizing the needle mold mounting positioning posts and needle mold mounting clip holes.

[0020] In some embodiments, the product positioning component is detachably mounted on the base.

[0021] Therefore, this configuration allows the product positioning components of the overall single-board link test fixture to be replaced and installed according to the model that needs to be tested, thus enabling the single-board link test fixture to be universally adapted to various different models and to test various different models.

[0022] In some embodiments, the base is provided with product mounting pin holes, and the product positioning component is provided with product positioning pin holes corresponding to the product mounting pin holes.

[0023] Therefore, with this setup, the product positioning component can be installed and removed from the base simply by inserting and removing the pin, achieving a simple and quick function for installing and removing the product positioning component.

[0024] In some embodiments, a companion testing component is also included, which is detachably mounted on the base.

[0025] Therefore, this setup allows for the installation of the testing components (such as the testing board) via the testing component, and the detachable design makes it easier to maintain the testing component.

[0026] In some embodiments, an adapter assembly is also included, which is detachably mounted on the base.

[0027] Therefore, this configuration allows for the adapter to be used to connect the product's main connector pin-shaped cable, and the detachable design makes it easier to maintain the adapter. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] The present invention will now be described in further detail with reference to the accompanying drawings.

[0037] Figure 1 The schematic diagram illustrates the overall composition of a single-board link test fixture according to an embodiment of this utility model, with reference to... Figure 1 As shown, the single-board link test fixture of this utility model includes a base 1, on which a product positioning component 4 and a pin mold mounting component 2 are disposed. The product positioning component 4 is a structure for mounting the product, and the pin mold mounting component 2 is a structure for mounting the pin mold component 3. The pin mold mounting component 2 is detachably mounted on the base 1, thereby allowing the pin mold to be detachably mounted onto the base 1.

[0038] Specifically, the base 1 is provided with a needle mold mounting pin hole 11, and the needle mold mounting assembly 2 is provided with a needle mold positioning pin hole 23 corresponding to the needle mold mounting pin hole 11, so that the needle mold mounting assembly 2 can be positioned and installed on the base 1 by inserting a pin.

[0039] Reference Figure 2 As shown, the needle mold mounting assembly 2 includes a needle mold base plate 21, which is a quadrilateral structure. Four needle mold mounting pin holes 11 are provided on the upper surface of the base 1. Correspondingly, four needle mold positioning pin holes 23 are also provided on the needle mold mounting assembly 2. The four needle mold positioning pin holes 23 are located at the four corners of the needle mold base plate 21. Therefore, the needle mold mounting assembly 2 can be positioned and installed by inserting pins, achieving quick installation. At the same time, because the needle mold mounting pin holes 11 on the base 1 are located on the upper surface of the base 1, operators can more easily insert or remove pins during operation to install the needle mold mounting assembly 2.

[0040] In addition, a needle mold mounting positioning post 13 can be provided on the base 1, and a needle mold mounting hole 14 corresponding to the position of the needle mold mounting positioning post 13 can be provided on the needle mold base plate 21, so that when the needle mold base plate 21 is installed on the base 1, the initial positioning can be achieved by the design of the needle mold mounting positioning post 13 and the needle mold mounting hole 14, and then the pin can be used for further installation.

[0041] Reference Figure 2 As shown, the base 1 is provided with two needle mold mounting positioning posts 13, and two needle mold mounting holes 14 are also provided. The needle mold mounting holes 14 are located on the needle mold base plate 21 near both sides. Thus, through the design of the two sets of needle mold mounting positioning posts 13 and needle mold mounting holes 14, the initial positioning of the needle mold base plate 21 can be achieved.

[0042] In addition to the needle mold base plate 21, the needle mold mounting assembly 2 also includes a slot 22 provided on the needle mold base plate 21. The bottom of the needle mold assembly 3 is provided with a boss 33 that matches the slot 22, so that the needle mold assembly 3 can be installed and positioned on the needle mold base plate 21 through the insertion of the slot 22 and the boss 33.

[0043] Furthermore, to improve the stability of the needle mold assembly 3 mounted on the needle mold mounting assembly 2, a spring plunger structure 34 can be provided on one side of the boss 33, and a positioning hole 25 adapted to the spring plunger structure 34 is provided at a corresponding position on the slot 22. Thus, when the boss 33 is inserted into the slot 22, the spring plunger structure 34 on the boss 33 will also engage with the positioning hole 25, thereby limiting the boss 33 from disengaging from the slot 22.

[0044] Specifically, the spring plunger structure 34 can be configured as a structure formed by a combination of a convex ball and a spring, so that the convex ball moves beyond the protrusion 33 under the drive of the spring, thereby achieving the corresponding locking function. Of course, the spring plunger structure 34 can also be configured with other commonly used structures, and this utility model does not limit it in this regard.

[0045] In addition, to facilitate the removal of the needle mold assembly 3 from the needle mold mounting assembly 2, the positioning hole 25 on the needle mold base plate 21 can also be designed to penetrate the inner wall of the slot 22 to the side of the needle mold base plate 21. With this design, when it is difficult for the operator to remove the needle mold assembly 3 by external force alone, a thin object such as a toothpick can be inserted into the positioning hole 25 to apply pressure to the convex ball, thereby removing the needle mold assembly 3 from the needle mold mounting assembly 2.

[0046] For example, refer to Figure 3 and Figure 4 As shown, in Figure 3 and Figure 4 In the illustrated embodiment, a slot 22 is provided on the top surface of the needle mold base plate 21, while a boss 33 of matching size is provided on the bottom of the needle mold assembly 3. A spring plunger structure 34 is provided on the side of the boss 33 facing the front of the needle mold assembly 3, and the spring plunger structure 34 is a combination of a convex ball and a spring. Similarly, a positioning hole 25 corresponding to the spring plunger structure 34 is provided on the side of the slot 22 facing the front of the needle mold assembly 3. Since the slot 22 is a structure formed on the needle mold base plate 21, the positioning hole 25 is set to penetrate the needle mold base plate 21.

[0047] Reference Figure 5 As shown, when the needle mold assembly 3 needs to be installed onto the needle mold mounting assembly 2, simply insert the boss 33 on the needle mold assembly 3 into the slot 22 provided on the needle mold base plate 21, and let the spring plunger structure 34 engage with the positioning hole 25 to complete the installation of the needle mold assembly 3. When it is necessary to disassemble the needle mold assembly 3, the operator can apply external force to the needle mold assembly 3 to make the convex ball retract and disengage from the positioning hole 25 against the spring force, thereby achieving the disassembly of the needle mold assembly 3. The operator can also insert a thin, long object such as a toothpick into the positioning hole 25 to apply pressure to the convex ball, thereby removing the needle mold assembly 3 from the needle mold mounting assembly 2.

[0048] Understandably, when performing single-board link testing, the pin molds that need to connect to the connectors on the device under test may have various structural styles. (Refer to...) Figure 3 As shown, in Figure 3In the illustrated embodiments, the needle mold assembly 3 has five different structural styles. In some possible embodiments, the dimensions of the corresponding boss 33 and slot 22 are also set differently for different structural styles of the needle mold assembly 3. This arrangement allows operators to directly install the needle mold assembly 3 according to the dimensions of the boss 33 and slot 22, effectively improving the ease of installation and reducing the probability of incorrect installation of the needle mold assembly 3.

[0049] In addition, in some possible embodiments, the needle mold mounting assembly 2 may also be provided with a limiting platform 24 for abutting against the side of the needle mold assembly 3. The limiting platform 24 can support the needle mold assembly 3, making the needle mold assembly 3 more stable during actual use after being mounted on the needle mold mounting assembly 2. Specifically, the needle mold assembly 3 includes a housing 31 and a needle 32. The needle 32 is located on one side of the housing 31, and the limiting platform 24 can be located on the side of the housing 31 opposite to the side where the needle 32 is located, thus supporting the back of the needle mold assembly 3. The above arrangement allows the limiting platform 24 to be located on the back of the needle mold assembly 3 during use, thereby preventing it from falling off due to excessive force when mating with the connector.

[0050] For example, refer to Figure 3 As shown, in Figure 3 In the illustrated embodiment, the limiting platform 24 is configured as a rectangular boss 33 and is located behind the position on the needle mold base plate 21 where the needle mold assembly 3 is mounted. Thus, when the needle mold assembly 3 is mounted on the needle mold base plate 21, the limiting platform 24 abuts against the back of the needle mold assembly 3, thereby supporting the back of the needle mold assembly 3 during use and improving the connection stability of the needle mold assembly 3 during operation.

[0051] In some possible implementations, the needle mold base plate 21 may also be configured such that the height of the plane on which the needle mold assembly 3 is not mounted is lower than the height of the plane on which the needle mold assembly 3 is mounted. Specifically, refer to... Figure 3 As shown, in Figure 3 In the illustrated embodiment, the position on the needle mold base plate 21 corresponding to the bottom contour of the needle mold assembly 3 is higher than other planes on the needle mold base plate 21 where the needle mold assembly 3 is not located. This arrangement reduces the overall thickness of the needle mold base plate 21, thereby lowering the overall cost.

[0052] The product positioning component 4 can be detachably mounted on the base 1. Specifically, the base 1 can have product mounting pin holes 12, and the product positioning component 4 can have product positioning pin holes corresponding to the product mounting pin holes 12. This method is consistent with the detachable connection method between the needle mold mounting component 2 and the base 1 described above, thereby unifying the installation and disassembly method of the overall structure and improving the convenience of operation for operators.

[0053] Reference Figure 1 and Figure 2 As shown, in Figure 1 and Figure 2 In the illustrated embodiment, the product positioning component 4 includes a product base plate 41, which has a quadrilateral structure. Four product positioning pin holes are provided at the four corners of the product base plate 41. Similarly, four product mounting pin holes 12 are provided at corresponding positions on the base 1. Additionally, the base 1 is provided with product mounting positioning posts 15, and the product base plate 41 is provided with product mounting locking holes 16, allowing for initial positioning of the product base plate 41 through the engagement of the product mounting positioning posts 15 and the product mounting locking holes 16. Subsequently, the product positioning component 4 can be positioned and installed by inserting pins, enabling rapid installation.

[0054] The top surface of the product base plate 41 is provided with four product mounting posts 42, which are used to connect with the mounting holes on the corresponding models. When it is necessary to test other different models, the product positioning component 4 can be quickly replaced to adapt to different models and test the corresponding models.

[0055] Additionally, refer to Figure 1 and Figure 2 As shown, in some possible implementations, the overall fixture may further include a test assembly 5, which is also detachably mounted on the base 1. Specifically, the test assembly 5 is used to mount the structure and modules of the test section. The test assembly 5 can be mounted on the base 1 using studs, enabling quick replacement.

[0056] Continue to refer to Figure 1 and Figure 2 As shown, in some possible embodiments, the overall fixture may further include an adapter component 6, which is also detachably mounted on the base 1. Specifically, the adapter component 6 is used for the main connector pin-type cable adapter. The adapter component 6 can be mounted on the base 1 via studs for quick replacement.

[0057] This utility model's single-board link test fixture detachably mounts the pin mold onto the pin mold mounting assembly 2. The pin mold mounting assembly 2 and the base 1 are connected by pin mold mounting pin holes 11 and pin mold positioning pin holes 23. Therefore, the installation and removal of the pin mold mounting assembly 2 on the base 1 can be completed simply by inserting and removing the pins, achieving a simple and quick installation and removal function for the pin mold assembly 3. Simultaneously, the product positioning assembly 4 is also detachably connected to the base 1, allowing for replacement of the corresponding product positioning assembly 4 according to the model to be tested, achieving adaptability to different models and improving the overall fixture's versatility. The detachable connection method, using pins and pin holes for insertion, is convenient and quick to operate, effectively reducing fixture changeover time.

[0058] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
