Description

Technical Field

[0001] This utility model belongs to the technical field of pin transformers and their accessories, and in particular relates to a pin protection structure for a pin transformer. Background Technology

[0002] A pin transformer is a type of miniature transformer used in electronic devices. It is mounted on the circuit board of an electronic device via pins and mainly consists of three parts: the housing, the coil assembly, and the pins. The housing has a split design, facilitating replacement of damaged components. Because the pins are exposed on the outside of the housing, they are easily damaged by contact with other objects, necessitating the addition of pin protection structures.

[0003] Patent application CN220441084U discloses a GaN device with pin protection, relating to the field of GaN device technology. The device includes a device body with eight fixing rings sleeved on its outer wall, arranged in a linear array. A reinforcing rod connects two adjacent fixing rings. Slots are formed on opposite sides of the two outermost fixing rings. A surrounding plate is connected to the opposite sides of the two outermost fixing rings. A fixing block is connected to the inner wall of the eight fixing rings. In this invention, pulling one fixing plate causes a sleeve to slide on the outer wall of a T-shaped rod, moving a pressure block upwards. The device body is then inserted into the eight fixing rings. Releasing the fixing plate causes the sleeve and pressure block to move downwards, pressing the device body firmly. The surrounding plate and protective plate enclose the pins of the device body, preventing them from bending or breaking due to compression.

[0004] The aforementioned GaN device with pin protection features a retaining ring at the bottom of the device body, which is then fixed above the retaining ring by a clamping assembly. However, the clamping assembly is fixed at both ends of the retaining ring, meaning its position is not adjustable. Different types of device bodies have different length and width specifications, so using a uniform retaining ring and clamping assembly for fixation would result in incompatibility. Furthermore, the retaining ring has protective plates, surrounding plates, and fixing plates on both sides. After the device body is fixed above the retaining ring, the surrounding plates and fixing plates protect the pins. While this protects the front of the pins, the sides and top remain exposed. The distance between the protective plate and the pins is adjusted by a telescopic rod, which is an elastic component with a certain degree of resilience. When it rebounds, the protective plate can impact the pins, further damaging them. Therefore, we provide a pin protection structure for a pin-type transformer to solve the problems mentioned above.

The fixing component 203 includes a spring 203c fixed in the rod groove 202b. The other end of the spring 203c is fixedly connected to the push plate 203a, and one end of the push plate 203a is rotatably connected to the rod groove 202b through the plate shaft 203b. A fixing block 203d is fixed to the front side wall end of the push plate 203a. The sliding rods 202a are slidably inserted into the sliding slots 201a, and the fixing block 203d cooperates with the fixing holes 201b.

Then, the adjusting bracket 202 is pushed so that the sliding rod 202a on it is inserted into the sliding slot 201a. At the same time, the fixing block 203d moves from the fixing hole 201b at the outermost end of the sliding slot 201a until the adjusting bracket 202 is fixed on the other side of the pin transformer body 1 and the pushing of the adjusting bracket 202 is stopped, thus completing the fixing effect of the fixing component 2 on the pin transformer body 1.

[0034] Example 2

At this time, the pin sleeve 304 is away from the pin body 102. Then, the rotating ear 302a is held and rotated, which drives the stud 302 to rotate on the top of the mounting bracket 301. The abutment plate 303 on the end of the stud 302 gradually approaches the pin transformer body 1. At the same time, the pin sleeve 304 on the abutment plate 303 also approaches the pin body 102 until the pin sleeve 304 is fitted onto the outside of the pin body 102.
