Clamping structure of plug-in inductor framework

Abstract

The utility model discloses a clamping structure of a pluggable inductor framework, which comprises a shell and an embedded socket communicated with the shell, a magnetic core is inserted in the socket, an elastic piece is arranged on the inner wall of the socket, and the abutting end of the elastic piece is connected with a convex column on the magnetic core. According to the inductor disclosed by the utility model, the magnetic core can be inserted into the shell to be in contact with the coil in the shell and can also be pulled out of the socket through the arrangement of the socket, so that the inductor is more suitable for some special use environments. After the magnetic core is inserted into the socket, the position of the magnetic core is limited due to the fact that the elastic piece abuts against the protruding column on the magnetic core, namely the magnetic core is located in the center of the shell and does not generate eccentricity, and frequent faults caused by eccentricity of the magnetic core are avoided.

[0020] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the following will make a detailed description of the specific embodiments of the present application in combination with the drawings of the specification.

[0021] In the following description, a lot of specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can be practiced in other ways different from those described herein, and those skilled in the art can make similar generalizations without departing from the spirit of the present application, therefore, the present application is not limited to the specific embodiments disclosed below.

[0022] Secondly, the "one embodiment" or "embodiment" referred to herein means that the specific features, structures or characteristics can be included in at least one implementation of the present application. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent of or mutually exclusive with other embodiments.

[0023] Embodiment

[0024] Reference Figs. 1-3 For the embodiment of the present application, the embodiment provides a clamping structure of a plug-in inductor skeleton, as shown in Fig. 1 The shell 10 and the socket 20 embedded in the shell 10 are communicated, the magnetic core 30 is inserted into the socket 20, the elastic member 21 is arranged on the inner wall of the socket 20, and the abutting end of the elastic member 21 is in contact with the protruding column 31 on the magnetic core 30. The opening of the socket 20 enables the magnetic core 30 to be inserted into the shell 10 and in contact with the coil in the shell 10, and the magnetic core 30 can also be pulled out in the socket 20, so that the inductor is more suitable for some special use environment. After the magnetic core 30 is inserted into the socket 20, the position of the magnetic core 30 is limited due to the abutment of the elastic member 21 on the protruding column 31 on the magnetic core 30, that is, the magnetic core 30 is located in the center of the shell 10 and cannot be eccentric, so as to avoid frequent failures caused by the eccentricity of the magnetic core 30.

[0025] Illustratively, the elastic member 21 includes a baffle 211 arranged on the outer side edge of the socket 20, and the baffle 211 is in contact with the protruding column 31. The baffle 211 is inclined, and the baffle 211 fixed on the socket 20 is inclined towards the magnetic core 30, so that when the magnetic core 30 moves, the protruding column 31 can press the baffle 211, the baffle 211 elastically deforms and the protruding column 31 passes through the baffle 211 with the magnetic core 30, and when the baffle 211 passes through the baffle 211, if the user pulls the magnetic core 30 out of the socket 20, the baffle 211 abuts against the protruding column 31 to limit the movement of the magnetic core 30, and then the magnetic core 30 connected with the shell 10 is aligned left and right and located in the center of the shell 10.

[0026] Illustratively, the displacement space 22 is arranged between the baffle 211 and the end wall of the socket 20. With the opening of the displacement space 22, the user can make the baffle 211 close to the end wall of the socket 20 by pressing the baffle 211, and leave a space for the protruding column 31 to move out of the socket 20.

[0027] The displacement space 22 is provided with a stretching strip 23, one end of which is in contact with the outer wall of the shell 10 through the blocking piece 211. In order to facilitate the user to pull out the magnetic core 30 connected to the shell 10, the stretching strip 23 is fixed on the side of the blocking piece 211 close to the end wall of the socket 20, and one end of the stretching strip 23 extends to the outside through the blocking piece 211, so that the operator can move the blocking piece 211 in contact with one end of the convex column 31 and close to the end wall of the socket 20 by pressing or pulling the stretching strip 23.

[0028] The stretching strip 23 is divided into a first part 231 connected with the blocking piece 211 and a second part 232 bent after passing through the blocking piece 211, and one end of the second part 232 away from the first part 231 is in contact with the outer wall of the shell 10. In order to avoid that the blocking piece 211 is displaced to close to the socket 20 and the position of the magnetic core 30 is deviated due to the accidental contact of the stretching strip 23 by other objects when the shell 10 is used, the stretching strip 23 is provided with the first part 231 and the second part 232, the first part 231 is located in the displacement space 22, and the first part 231 is fixed on the side of the blocking piece 211 close to the end wall of the socket 20, the fixed position of the first part 231 is close to the convex column 31, the second part 232 is integrally formed with the first part 231, and the second part 232 is bent after passing through the blocking piece 211, and the bent end of the second part 232 corresponds to the outer wall of the shell 10, so as to reduce the occupied space of the second part 232 and avoid that the second part 232 moves under the elastic reset of the blocking piece 211 and moves into the displacement space 22, thereby affecting the separation of the magnetic core 30 and the shell 10.

[0029] The shell 10 is provided with an inner recessed shielding groove 40, and one end of the second part 232 away from the first part 231 is in contact with the inner wall of the shielding groove 40. In order to further avoid the accidental contact of the stretching strip 23, the shielding groove 40 is provided on the shell 10, and the second part 232 is located in the shielding groove 40. Since the shielding groove 40 is an inner recessed arc shape, the second part 232 located in the shielding groove 40 of the shell 10 is not easy to be accidentally contacted when the shell 10 is used.

[0030] The convex column 31 is not less than two and is arranged longitudinally on the magnetic core 30 at equal intervals.
