Description

Technical Field

[0001] This utility model belongs to the field of inductor technology, specifically relating to a common-mode inductor limiting structure. Background Technology

[0002] Common-mode inductors, also known as common-mode chokes, are commonly used in computer switching power supplies to filter common-mode electromagnetic interference signals. Common-mode inductors play a crucial role in electronic devices and circuits by suppressing common-mode interference and improving the circuit's anti-interference capability. A common-mode inductor typically consists of a magnetic core and a coil wound around it; the coil is secured by structural constraints.

[0003] When existing common-mode inductors are in operation, the coil will vibrate or deviate, which will cause certain interference to the circuit. This vibration is more obvious during performance testing, especially since the inductor is not soldered to the circuit board, which will affect the accuracy of the test structure. Utility Model Content

[0004] The purpose of this invention is to provide a common-mode inductor limiting structure, which aims to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

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.

[0028] Example 1

[0029] Reference Figure 1-5 This is the first embodiment of the present invention, which provides a common-mode inductor limiting structure, including:

[0030] Inductor assembly 100 includes a base 101, a magnetic ring 102 mounted on the upper end of the base 101, a coil 103 wound in the middle of the magnetic ring 102, and a pole 104 mounted on the side wall of the base 101. The end of the coil 103 extends to the side wall of the base 101, and the end of the coil 103 is welded to the upper end of the pole 104.

[0031] The mounting assembly 200 includes a support base 201, a locking block 202 rotatably mounted on the upper side wall of the support base 201, and an pole post 203 mounted on the upper end of the support base 201. The support base 201 is inserted into the bottom of the base 101, the locking block 202 is rotatably locked onto the outer side wall of the base 101, and one end of the pole post 203 is in elastic contact with the lower end face of the pole 104.

[0032] The base 101 is used to mount a magnetic ring 102 with a coil 103. The end of the coil 103 is connected to a pole 104 mounted on the side wall of the base 101, which facilitates power supply to the coil 103 through the pole 104. When the input signal is applied to the winding simultaneously, the signal will flow through the inductor in the same direction, generating a common magnetic field, which enables the inductor to operate normally. A support base 201 with a locking block 202 is added to the bottom of the base 101. The support base 201 is used to mount the base 101. The locking block 202 can cooperate with the support base 201 to lock onto the outer side wall of the base 101, limiting the position of the base 101, maintaining the stability of the position of the base 101, and preventing the base 101 from loosening. At the same time, a pole post 203 is installed in the middle of the support base 201 to connect with the pole 104, which facilitates the connection of the inductor's pole 104 to the connector of the test equipment, making installation convenient.

[0033] Specifically, a spring piece 204 is installed in the middle of the cavity inside the support base 201, and the upper end of the spring piece 204 is connected to the bottom of the pole post 203 by bolts.

[0034] A spring clip 204 is installed inside the support base 201 to connect with the pole post 203. The spring clip 204 can keep the pole post 203 protruding from the side wall of the support base 201 and in contact with the pole 104, so as to facilitate power supply to the inductor and maintain the normal operation of the inductor.

[0035] Furthermore, a wire 205 is sealed and installed on one side of the support 201, and the end of the wire 205 is connected to the side wall of the spring piece 204 by bolts.

[0036] Among them, a wire 205 is installed on the side wall of the support base 201 to connect with the spring piece 204, so as to facilitate the connection with the test equipment through the wire 205 to test the performance of the inductor.

[0037] Furthermore, a spring 206 is engaged with the inner side of the lower end of the locking block 202, and the other end of the spring 206 is installed on the inner wall of the support base 201.

[0038] In this design, a spring 206 is added to the side wall of the locking block 202 and connected to the support base 201. The support base 201, in conjunction with the spring 206, provides an outward elastic force to the bottom of the locking block 202, thereby positioning the upper end of the locking block 202 to be stably locked onto the outside of the base 101, preventing the base 101 from loosening.

[0039] Preferably, the upper inner sidewall of the card block 202 is in contact with the base 101, and the top of the card block 202 is provided with a sloping structure that matches the base 101.

[0040] Among them, a sloping structure is added to the upper end of the locking block 202 to facilitate the insertion of the base 101 into the upper end of the support 201. The locking block 202 is used to limit the base 101 and prevent the base 101 and other components from becoming loose.

[0041] It should be noted that a support rod 207 is movably inserted into one side of the middle of the support base 201. The end of the support rod 207 is inserted into the middle of the protrusion at the lower end of the base 101, and a tension spring 208 is sleeved on the side wall of the support rod 207. The other end of the tension spring 208 is fixedly installed on the side wall of the support base 201.

[0042] Among them, a support rod 207 with a tension spring 208 is added to the side wall of the support base 201. The support rod 207 is inserted into the middle of the bottom protrusion of the base 101, which can work with the support base 201 to further limit the base 101, prevent the base 101 from loosening from the upper end of the support base 201, and maintain the stability of the connection structure between the support base 201 and the base 101.

[0043] Preferably, a gasket 105 is attached to the bottom of the magnetic ring 102, and the lower end of the gasket 105 is installed at the middle position of the upper end of the base 101.

[0044] Among them, a shim 105 is added at the connection between the magnetic ring 102 and the base 101. The shim 105 can buffer the magnetic ring 102, reduce the vibration generated by the magnetic ring 102 during operation, and also prevent the base 101 from scratching the magnetic ring 102.

[0045] In summary, the base 101 is used to mount a magnetic ring 102 with a coil 103. The end of the coil 103 is connected to a pole 104 mounted on the side wall of the base 101, facilitating power supply to the coil 103 through the pole 104. When input signals are applied to the winding simultaneously, the signals will flow through the inductor in the same direction, generating a common magnetic field, enabling the inductor to operate normally. A support base 201 with a locking block 202 is added to the bottom of the base 101. The support base 201 is used to mount the base 101. The locking block 202 can engage with the support base 201 on the outer side wall of the base 101 to limit the position of the base 101, maintain the stability of the base 101, and prevent the base 101 from loosening. At the same time, a pole post 203 is installed in the middle of the support base 201 to connect with the pole 104, facilitating the connection of the inductor's pole 104 to the connector of the test equipment, making installation convenient.
