Description

Technical Field

[0001] This utility model belongs to the technical field of pin transformers, and in particular relates to a pin anti-detachment structure for pin transformers. Background Technology

[0002] Pin-type transformers are common electronic components in electronic devices. They have advantages such as flexible adjustment of input and output voltage ratios, convenient installation and disassembly, and high reliability. They are widely used in power supply products such as televisions, computers, and mobile phone chargers, as well as audio equipment, to solve power interference problems. They are made by connecting multiple coils in series or parallel through pins, so that the input and output voltage ratios of the transformer can be adjusted at any time to meet different circuit requirements.

[0003] However, due to the small size and light weight of pin-type transformers, the pins on them may fall off during installation if bumped or knocked, rendering the pin-type transformer unusable. To address this issue, we provide a pin-locking structure to prevent pin detachment. Utility Model Content

[0004] The purpose of this utility model is to provide a pin anti-detachment structure for a pin transformer. The anti-detachment sleeve is used to put the threaded strip plate on the corresponding pin to achieve the function of preventing the pin from detaching. At the same time, the anti-detachment sleeve can be removed from the pin to disassemble and replace it.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a pin anti-detachment structure for a pin-type transformer, comprising a transformer body; an electrical contact plate is fixed to the end face of the transformer body, and multiple pins are fixed to the electrical contact plate opposite to the end face of the transformer body in a linearly evenly distributed manner; each pin is fitted with an anti-detachment sleeve plate, and a circular plate fitted onto the pin is fixed to the end face of the anti-detachment sleeve plate; multiple threaded strips are fixed to the circular plate opposite to the end face of the anti-detachment sleeve plate; two elastic plates are fixed to the periphery of the anti-detachment sleeve plate in a circular evenly distributed manner, and a retaining strip is fixed to the opposite face of the two elastic plates of each anti-detachment sleeve plate.

[0007] The present invention is further configured such that a notch is provided on the upper surface of the electrical contact plate at the position between two adjacent pins, and each elastic plate is inserted into the corresponding notch.

[0008] The present invention is further configured such that an assembly port is provided at the position of the corresponding card strip on the end face of the electrical connection plate, and each card strip is respectively set in the corresponding assembly port.

[0009] The present invention is further configured such that a stop block is fixed at the end of each threaded strip, and a friction pad that is in contact with the pin surface is fixed on the inner wall of the threaded strip.

[0010] The present invention is further configured such that a locking sleeve is fitted on a plurality of threaded plates evenly distributed in a ring, and an inner threaded ring that is helically connected to the plurality of threaded plates is fixed at the end of the locking sleeve relative to the anti-loosening sleeve plate.

[0011] The present invention is further configured such that a conical ring block is fixed on the inner side wall of the locking sleeve, and the narrow end of the conical ring block is opposite to the position of the stop block.

[0012] The present invention is further configured such that multiple stops are located inside the locking sleeve between the inner threaded ring and the conical ring block, and are in contact with the inside of the locking sleeve.

[0013] This utility model has the following beneficial effects:

[0014] 1. Place the anti-detachment sleeve plate and the circular plate on the corresponding pins, thereby controlling multiple threaded strip plates evenly distributed in a ring to be placed on the pins, so that the threaded strip plates clamp the pins. At the same time, use the elastic plate in combination with the electrical connection plate through the clamping strip to install the anti-detachment sleeve plate on the transformer body. Therefore, through the compression and dragging of the pins by the threaded strip plates, the pins are prevented from detaching.

Detailed Implementation

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Example 1

[0027] Please see Figures 1 to 6 This utility model is a pin anti-detachment structure for a pin transformer. The threaded strip 202 is fitted onto the corresponding pin 101 by the anti-detachment sleeve 2 to achieve the function of preventing the pin 101 from detaching. At the same time, the anti-detachment sleeve 2 can be removed from the pin 101 to disassemble and replace it.

[0028] Specifically, the transformer body 1 has an electrical connection plate 102 fixed on its end face. The electrical connection plate 102 has multiple pins 101 arranged linearly and evenly on the opposite end face of the transformer body 1. Each pin 101 is fitted with an anti-detachment plate 2. The end face of the anti-detachment plate 2 is fixed with a circular plate 201 fitted on the pin 101. Each circular plate 201 has multiple threaded strips 202 arranged in a ring on the opposite end face of the anti-detachment plate 2. Two elastic plates 203 arranged in a ring are fixed on the periphery of the anti-detachment plate 2. Each anti-detachment plate 2 has a retaining strip 204 fixed on the opposite face of the two elastic plates 203.

[0029] The operation process of this embodiment is as follows: the anti-detachment plate 2 and the circular plate 201 are placed on the corresponding pin 101, thereby controlling multiple threaded strips 202 arranged in a ring to be placed on the pin 101, so that the threaded strips 202 clamp the pin 101. At the same time, the elastic plate 203 is used in combination with the electrical connection plate 102 through the clamping strip 204, so that the anti-detachment plate 2 is installed on the transformer body 1. Therefore, through the compression and dragging of the pin 101 by the threaded strips 202, the pin 101 is prevented from detaching. At the same time, when disassembling the anti-detachment plate 2, the anti-detachment plate 2 can be disconnected from the electrical connection plate 102, so as to facilitate the removal of the anti-detachment plate 2 from the pin 101 for disassembly and replacement.

[0030] Example 2

[0031] Please see Figure 2 and Figure 6Based on Example 1, the assembly port 104 limits the locking strip 204, thereby improving the assembly stability of the anti-detachment plate 2.

[0032] Specifically, the upper end face of the electrical connection plate 102 is provided with a notch 103 at the position between two adjacent pins 101, and each elastic plate 203 is inserted into the corresponding notch 103. The end face of the electrical connection plate 102 is provided with an assembly port 104 at the position corresponding to the locking strip 204, and each locking strip 204 is respectively set in the corresponding assembly port 104.

[0033] The operation process of this embodiment is as follows: by inserting the elastic plate 203 into the corresponding recess 103, the retaining strip 204 on the side wall of the elastic plate 203 will be directly inserted into the assembly port 104. The retaining strip 204 is limited by the assembly port 104 to ensure the stable connection between the elastic plate 203 and the electrical connection plate 102.

[0034] Example 3

[0035] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5 Based on Example 1, the locking sleeve 3 rotates along the threaded strip 202 via the inner threaded ring 301, and the conical ring block 302 squeezes the multiple threaded strips 202, thereby increasing the clamping degree of the threaded strip 202 on the pin 101.

[0036] Specifically, each end of the threaded strip 202 is fixed with a stop 205, and the inner wall of the threaded strip 202 is fixed with a friction pad 206 that is in contact with the surface of the pin 101. A locking sleeve 3 is fitted on a plurality of threaded strips 202 evenly distributed in a ring. The end of the locking sleeve 3 relative to the anti-disengagement plate 2 is fixed with an inner threaded ring 301 that is spirally connected to the plurality of threaded strips 202. A conical ring block 302 is fixed on the inner side wall of the locking sleeve 3, and the narrow end of the conical ring block 302 is opposite to the position of the stop 205. The plurality of stop blocks 205 are all located inside the locking sleeve 3 between the inner threaded ring 301 and the conical ring block 302, and are in contact with the inside of the locking sleeve 3.

[0037] The operation process of this embodiment is as follows: With the above structure, when it is necessary to improve the tightness between the threaded plate 202 and the pin 101, the locking sleeve 3 can be controlled to rotate along the threaded plate 202. As a result, the locking sleeve 3 will drive the conical ring block 302 to move towards the stop block 205. As the locking sleeve 3 gradually goes deeper, the conical ring block 302 will compress the stop block 205, thereby driving the threaded plate 202 to be relatively squeezed, so that the friction pad 206 on the inner side of the threaded plate 202 is tightly attached to the pin 101, thereby improving the clamping degree of the threaded plate 202 on the pin 101.
