Description

Technical Field

[0001] The utility model relates to the field of micro transformers, in particular to a micro transformer with a protection structure. Background Art

[0002] Micro transformers use the principle of electromagnetic induction to transfer electrical energy between two circuits. Their basic structure is the same as that of conventional transformers, consisting of a magnetic core and windings. Micro transformers have the advantages of high power density, high efficiency, low leakage inductance, good heat dissipation, and low cost.

[0003] For example, a miniature transformer with a protective structure, for example, patent publication number CN219916850U, includes a transformer body, a groove is provided on one side of the transformer body, a mounting plate is provided inside the groove, a connection block is fixedly installed on the top of the mounting plate, a protective plate is provided on one side of the mounting plate, and a damper is fixedly installed on one side of the mounting plate. The damper is provided to absorb the impact force, so that the impact force is not easily directly transmitted to the transformer body, which is beneficial to prevent the transformer body from being damaged due to impact. However, the above device is prone to cause the transformer body to loosen from the circuit board when impacted, thereby affecting the use.

[0004] Therefore, in order to solve the above problems, a micro transformer with a protective structure has been developed, which can prevent the conductive pins from being loosened from the circuit board when impacted and improve the plugging stability. Utility Model Content

[0005] In order to overcome the disadvantage of the existing device that the transformer body and the circuit board are easily loosened when impacted, thus affecting the use, the utility model provides a micro transformer with a protective structure that can prevent the conductive pins from loosening from the circuit board when impacted and improve the plugging stability.

[0006] The technical implementation scheme of the utility model is: a micro transformer with a protective structure, including a shell, a conductive pin, a transformer structure and a protective mechanism, a plurality of conductive pins are connected to the lower sides of the left and right parts of the shell, the transformer structure is connected to the shell, and the shell is provided with a protective mechanism for improving the stability of plugging.

[0007] Furthermore, the protective mechanism includes a protective cover, a support plate, a connecting rod, a suction cup and an elastic member. The protective cover is connected to the outer shell, and support plates are symmetrically connected to the left and right sides of the lower part of the protective cover. The support plates are slidably connected to connecting rods, and the bottoms of the connecting rods are connected to suction cups. Elastic members are connected between the connecting rods and adjacent support plates. When the conductive pins are connected to the circuit board, the outer shell moves downward to drive the protective cover to move downward. The movement of the protective cover drives the connecting rod and the suction cup downward through the support plate, so that the suction cup contacts the circuit board. The protective cover drives the support plate to continue to move downward so that the elastic member is stretched, thereby squeezing the suction cup so that it is adsorbed and fixed on the circuit board.

[0008] Furthermore, the elastic member is a telescopic spring.

[0009] Furthermore, a limit block is provided on the top of the connecting rod.

[0010] Furthermore, it also includes a shock absorbing mechanism, which includes a telescopic rod, a buffer spring and a buffer plate. The upper sides of the left and right parts of the shell are symmetrically connected with the telescopic rods, the buffer plate is connected between the telescopic ends of the telescopic rods, and the buffer spring is connected between the telescopic rods and the buffer plate. When the conductive pin accidentally loosens from the circuit board and falls, the buffer plate drives the telescopic rod to extend and retract under the action of the buffer spring, thereby buffering the impact force generated by the collision through the buffer plate, thereby avoiding damage to the transformer structure caused by the collision.

[0011] Furthermore, the buffer plate is a hollow structure, which is convenient for heat dissipation of the transformer structure.

[0012] The beneficial effects of the utility model are as follows: 1. The utility model makes the suction cup contact with the circuit board, and the protective cover drives the support plate to continue to move downward so that the telescopic spring is stretched, thereby squeezing the suction cup so that it is adsorbed and fixed on the circuit board, which can prevent the conductive pin from loosening from the circuit board when impacted, thereby improving the stability of the plug-in.

[0013] 2. The utility model uses the buffer spring to enable the buffer plate to drive the telescopic rod to extend and retract, so that the impact force generated by the collision is buffered by the buffer plate, which can achieve the effect of preventing the transformer structure from being damaged by the collision.

DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0019] A micro transformer with a protective structure, such as Figure 1 and Figure 2 As shown, it includes a shell 1, conductive pins 2, a transformer structure 3 and a protective mechanism 4. Five conductive pins 2 are connected to the lower sides of the left and right parts of the shell 1. The shell 1 is connected to the transformer structure 3, and the shell 1 is provided with a protective mechanism 4.

[0020] like Figure 1 and Figure 3 As shown, the protection mechanism 4 includes a protection cover 41, a support plate 42, a connecting rod 43, a suction cup 44 and a telescopic spring 45. The protection cover 41 is connected to the outer shell 1, and the left and right sides of the lower part of the protection cover 41 are symmetrically connected to the support plates 42, the support plates 42 are slidably connected to the connecting rods 43, the bottoms of the connecting rods 43 are connected to the suction cups 44, the connecting rods 43 are connected to the adjacent support plates 42 with telescopic springs 45, and the tops of the connecting rods 43 are provided with limit blocks.

[0021] When the utility model is in use, the conductive pin 2 needs to be plugged into the circuit board first. During the plugging process, the shell 1 moves downward to drive the protective cover 41 to move downward. The protective cover 41 moves through the support plate 42 to drive the connecting rod 43 and the suction cup 44 to move downward, so that the suction cup 44 contacts the circuit board. The protective cover 41 drives the support plate 42 to continue to move downward so that the telescopic spring 45 is stretched, thereby squeezing the suction cup 44 to make it adsorbed and fixed on the circuit board, thereby preventing the conductive pin 2 from loosening from the circuit board when impacted, thereby improving the plugging stability.

[0022] like Figure 1 and Figure 3 As shown, a shock absorbing mechanism 5 is also included, and the shock absorbing mechanism 5 includes a telescopic rod 51, a buffer spring 52 and a buffer plate 53. The telescopic rods 51 are symmetrically connected to the upper sides of the left and right parts of the shell 1, and the buffer plate 53 is connected between the telescopic ends of the telescopic rods 51. The buffer plate 53 is a hollow structure, which is convenient for heat dissipation of the transformer structure 3. The buffer spring 52 is connected between the telescopic rods 51 and the buffer plate 53.

[0023] When the shock absorbing mechanism 5 of the utility model is used, the impact force generated by the collision can be buffered and shock-absorbed. When the conductive pin 2 accidentally loosens from the circuit board and falls, under the action of the buffer spring 52, the buffer plate 53 drives the telescopic rod 51 to be extended and retracted, thereby buffering the impact force generated by the collision through the buffer plate 53, thereby preventing the transformer structure 3 from being damaged by the collision.

[0024] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
