Description

Technical Field

[0001] The utility model relates to the technical field of inductor assembly tools, in particular to a fixture convenient for testing inductors. Background Art

[0002] A reactor, also called an inductor, is an electrical component widely used in the power system. The reactor is assembled by a coil and an iron core. After the inductor is produced, a wiring terminal needs to be welded to each of the head and tail ends of the inductor coil. The current welding method is to fix the inductor and the wiring terminal on the fixture. One end of the wiring terminal overlaps with the end of the coil. Since the other end of the wiring terminal has a connection hole, a positioning pin matching the connection hole is provided on the fixture to limit the wiring terminal. After the wiring terminal is welded to the inductor coil, the inductor needs to be tested.

[0003] However, the positioning pin is usually fixedly connected to the fixture. After welding, the two ends of the inductor coil are connected in series. When testing, the inductor needs to be removed from the fixture to separate the connection hole of the wiring terminal from the positioning pin so that the two ends of the inductor coil are no longer in series before the inductor can be tested, which is rather troublesome. Summary of the Utility Model

[0004] Aiming at the above defects, the purpose of the utility model is to provide a fixture convenient for testing inductors, which solves the problem that the positioning pin is usually fixedly connected to the fixture and it is rather troublesome to remove the inductor from the fixture before the inductor can be tested after welding.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The following combines the drawings Figures 1 to 3 and further illustrates the technical solution of the present invention through specific implementation modes.

[0027] As Figures 1 - 3 shown, a jig for conveniently testing an inductor includes a base 1, a first carrier 2, a second carrier 3, and a lifting assembly 6;

[0028] The first carrier 2 and the second carrier 3 are fixed on both sides of the top end of the base 1. An inductor 4 is installed on the first carrier 2, and two terminals 5 are installed on the second carrier 3;

[0029] Two positioning pins 31 are movably inserted into the second carrier 3. A connection hole matching with the positioning pin 31 is provided at one end of each terminal 5. The lifting assembly 6 is installed on the second carrier 3. One ends of the two positioning pins 31 are installed at the lifting end of the lifting assembly 6. The lifting assembly 6 is used to drive the two positioning pins 31 to lift, so as to drive the two positioning pins 31 to be inserted into or separated from the corresponding connection holes.

[0030] In this solution, the lifting assembly is provided to drive the two positioning pins 31 to lift. When testing the inductor, it can avoid the two positioning pins 31 contacting the connection holes of the two terminals 5, so as to prevent the two ends of the coil of the inductor after welding from being connected in series and affecting the test.

[0031] It should be noted that the user installs the inductor 4 and the terminals 5 on the first carrier 2 and the second carrier 3 respectively. The connection hole of the terminal 5 is sleeved outside the positioning pin 31. The other end of the terminal 5 is lapped on the coil end of the inductor 4. Then, the other end of the terminal is connected to the coil end of the inductor by welding.

[0032] As Figure 3 shown, the lifting assembly 6 includes a pressure rod 61, a connecting block 62, a connecting plate 63 and a spring 64;

[0033] The pressure rod 61 is movably inserted into the second carrier 3. Connecting blocks 62 are respectively fixedly connected to the bottom end of the pressure rod 61 and the bottom ends of the two positioning pins 31. The three connecting blocks 62 are fixedly installed on the connecting plate 63. A spring 64 is connected between the bottom end of the connecting plate 63 and the top end of the base 1.

[0034] Specifically, since the three connecting blocks 62 are all fixed to the connecting plate 63, when pressing the pressure rod 61, the pressure rod 61 will drive the connecting plate 63 connected to the connecting block 62 to move downward. The spring 64 is compressed by the connecting plate 63. At the same time, the connecting plate 63 drives the two positioning pins 31 connected to the connecting block 62 to move downward, so that the two positioning pins 31 are moved out of the connection holes, avoiding the two ends of the coil of the inductor after welding from being connected in series. Then, the inductor can be tested. After the test is completed, release the pressure rod 61, and the spring 64 returns to its original state, thereby driving the pressure rod 61 to move upward, so that the positioning pins 31 are reset, which is convenient for the installation of the terminals that need to be welded later.

[0035] As Figure 3 shown, a slider 65 is fixed to one side of the connecting plate 63. A guide rail 66 is slidably installed on the side of the slider 65 away from the connecting plate 63. The guide rail 66 is fixed to the top end of the base 1.

[0036] Specifically, by the way that the slider 65 is slidably connected to the guide rail 66, the connecting plate 63 can drive the positioning pin 31 to lift more stably and smoothly.

[0037] As Figures 1 - 2 shown, an installation groove 21 is formed at the top end of the first carrier 2, and the bottom end of the inductor 4 is clamped in the installation groove 21.

[0038] Specifically, by the way that the inductor 4 is clamped in the installation groove 21, the disassembly and assembly between the inductor 4 and the first carrier 2 can be facilitated.

[0039] As Figures 1 - 2 shown, baffles 22 are provided on both the adjacent and opposite sides of the first carrier 2 and the second carrier 3, and the inductor 4 is located between the two baffles 22.

[0040] Specifically, the two baffles 22 are provided to limit and fix the inductor 4. Since during welding, the welding end of the welding device will apply force to the coil of the inductor 4, by providing the two baffles 22 to limit and fix the inductor 4, the phenomenon that the inductor 4 is skewed during welding and affects the welding quality can be avoided.

[0041] As Figures 1 - 2 shown, a first avoidance notch 23 is formed at the top end of the baffle 22 located between the first carrier 2 and the second carrier 3, and the first avoidance notch 23 is used to avoid the coil of the inductor 4.

[0042] Specifically, the provided first avoidance notch 23 can avoid interference of the baffle 22 with the coil of the inductor 4 when the inductor 4 is installed on the first carrier 2.

[0043] As Figure 3 shown, a support plate 32 is installed on the side wall of the second carrier 3, and two second avoidance notches 33 are formed at the top end of the support plate 32. The two wiring terminals 5 respectively penetrate through the corresponding second avoidance notches 33, and each wiring terminal 5 is in contact with the inner wall of the corresponding second avoidance notch 33.

[0044] Specifically, the second avoidance notches 33 provided at the top end of the support plate 32 are used to support the wiring terminals 5, and the wiring terminals 5 are in contact with the inner walls of the second avoidance notches 33 to avoid the deviation of the wiring terminals 7. And by the way that the positioning pin 31 cooperates with the connection hole, when the wiring terminal is placed in the second avoidance notch 33, the other end of the wiring terminal 5 just overlaps on the coil end of the inductor 4, which is convenient for the user to assemble and avoids the phenomenon that the wiring terminal 5 is deviated during welding and affects the welding quality.

[0045] As Figure 1As shown, a storage slot 7 is installed on the top of the base 1, and the storage slot 7 is used to store the wiring terminal 5.

[0046] Specifically, the storage slot 7 is provided to store the wiring terminal 5, so that the user can conveniently take the wiring terminal 5 for assembly.

[0047] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
