Description

Technical Field

[0001] This utility model relates to the field of adapter technology, and in particular to an adapter mechanism and a measurement interface adapter device. Background Technology

[0002] Electrical testing instruments, calibrators, and other field testing devices require frequent plugging and unplugging of voltage and current lines for voltage and current measurements during field use. This process can damage voltage and current jacks, affecting normal testing and the user experience for operators. Furthermore, operators need to send the products back to the manufacturer for re-inspection, increasing the workload of maintenance.

[0003] In existing technologies, wear-resistant materials and gold plating are commonly used to manufacture sockets to improve durability; alternatively, the structural design of the sockets is optimized to make them more robust and less prone to damage; or detailed operating procedures are developed to guide operators in correctly plugging and unplugging voltage and current lines, improving operators' awareness of equipment protection, and ensuring regular maintenance. However, plating that is too thin cannot provide sufficient protection, while plating that is too thick or uneven will affect the overall durability of the socket, and complex interface designs may increase potential points of failure and maintenance difficulty.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0031] Example 1, referring to Figure 1 This is the first embodiment of the present invention, which provides a transfer mechanism.

[0032] Specifically, it includes a conversion mechanism 100, which includes a wiring component 101. The wiring component 101 includes a terminal head 101a, which is an insulated interface and is used for connecting an external test terminal. One end of the terminal head 101a is welded to a terminal post 101b inside the supporting structure, and the end of the terminal post 101b away from the terminal head 101a is welded to an internally threaded connecting post 101d.

[0033] The adapter 102 includes a self-springing terminal head 102a, which can be connected to the measuring terminal of the field testing device. A connecting screw 102b is welded to one end of the self-springing terminal head 102a near the internal threaded connecting post 101d. The connecting screw 102b can be screwed into the internal threaded connecting post 101d to fix the self-springing terminal head 102a to the terminal 101b.

[0034] It should be noted that the internal threaded connecting post 101d and the connecting screw 102b are made of pure copper to ensure the transmission of electrical signals. At the same time, the threaded connection method of the internal threaded connecting post 101d and the connecting screw 102b can be adjusted according to the distance between the tester interface and the connection length.

[0035] Specifically, the terminal block 101b has threads on its surface; the wiring component 101 also includes a fixing nut 101c, which can be screwed onto the terminal block 101b. When the adapter mechanism 100 is assembled with the support mechanism 200, the fixing nut 101c can fix the terminal head 101a onto the front baffle 202a.

[0036] Example 2, refer to Figure 1 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a stop nut insertion limit for the adapter mechanism.

[0037] Specifically, the adapter 102 also includes a stop nut 102c, which is screwed onto the connecting screw 102b and abuts against one end of the self-spring-loaded terminal head 102a. When the self-spring-loaded terminal head 102a is connected to the testing device, the stop nut 102c can limit the insertion depth of the self-spring-loaded terminal head 102a.

[0038] The rest of the structure is the same as in Example 1.

[0042] Furthermore, the front baffle assembly 202 includes a front baffle 202a, which is made of an insulating plate and has a voltage transfer area and a current transfer area.

[0043] The front baffle assembly 202 also includes a voltage converter 202b, a current converter 202c, a direct current input interface 202d, a clamp-on current input interface 202e, and a first connection hole 202f;

[0044] Among them, voltage converter 202b is located in the voltage conversion area, and current converter 202c, direct current connection interface 202d, and clamp-on current connection interface 202e are located in the current conversion area; the number of the aforementioned interfaces can be set according to actual usage requirements.

[0045] Based on the requirements of commonly used testing equipment, several front baffle assemblies 202 and corresponding rear baffle assemblies 204 are also provided. When testing different equipment, different front baffle assemblies 202 and rear baffle assemblies 204 can be replaced and connected as needed.

[0046] The rear baffle assembly 204 includes a rear baffle 204a, which is an aluminum alloy metal plate. The rear baffle 204a has several adapter holes 204c, which correspond to voltage adapter 202b, current adapter 202c, direct current interface 202d, and clamp-on current interface 202e, respectively. The rear baffle 204a also has a third connection hole 204b.

[0047] The top plate assembly 203 includes a top plate 203a, which is an aluminum alloy metal plate, and a second connecting hole 203b is provided on the top plate 203a.

[0048] The bottom shell assembly 201 includes a bottom shell 201a, which is formed by bending an aluminum alloy metal plate. The bottom shell 201a has a U-shaped cross section. The top ends of both sides of the U-shape are bent to form a side plate 201b. A first fixing hole 201c is provided on the side plate 201b. Internal threaded posts 201d are provided on the four inner side ribs of the bottom shell 201a.

[0049] It should be noted that the first connecting hole 202f is opposite to the internal threaded hole on the front side of the internal threaded post 201d, and the front baffle 202a can be fixedly connected to the bottom shell 201a using bolts; the third connecting hole 204b is opposite to the internal threaded hole on the rear side of the internal threaded post 201d, and the rear baffle 204a can be fixedly connected to the bottom shell 201a using bolts; the second connecting hole 203b is opposite to the first fixing hole 201c, and the top plate 203a can be fixedly connected to the bottom shell 201a using bolts.

[0050] To facilitate the installation of this device, the aforementioned bolts are of a uniform specification.

[0051] The rest of the structure is the same as in Example 2.

[0052] In use, select the appropriate front baffle assembly 202 and rear baffle assembly 204 according to the on-site testing equipment, and combine them together with the top plate assembly 203 and the bottom shell assembly 201 to form a support mechanism 200. Taking the adapter mechanism 100 for installing the voltage adapter interface 202b as an example, insert the terminal 101b along the voltage adapter interface 202b, and then screw the fixing nut 101c onto the terminal 101b to make the wiring component 101 firmly connected to the front baffle 202a. Then, insert the connecting screw 102b into the corresponding adapter through hole 204c and screw it onto the internal threaded connecting post 101d. Install the adapter mechanism 100 for all other interfaces in the same way. After installation, plug the self-springing terminal head 102a of this device into the testing equipment. When testing, simply plug the end to be tested into the terminal head 101a of this device to avoid wear and damage to the plug-in port of the testing equipment.

[0053] The threaded connection between the connecting screw 102b and the internal threaded connecting post 101d allows the adapter mechanism 100 to adapt to different distances between the front baffle 202a and the rear baffle 204a.

[0054] Furthermore, this device is assembled from front, rear, upper, and lower baffles. If the front baffle assembly is damaged, simply unscrew the bolts to replace the front baffle assembly.

[0055] In summary, the design of this device not only reduces wear and tear on field testing equipment, but also makes it easy to use, install, and maintain, and has good reliability.
