Description

A type of heat-riveted protective cover Technical Field

[0001] This utility model relates to the field of rotary transformer technology, specifically a heat-riveted protective cover. Background Technology

[0002] The existing protective cover uses a snap-on method, as shown in Figure 1, which requires manual assembly. This can lead to issues with the pressure applied by the personnel during assembly. Furthermore, the existing protective cover does not allow direct observation of the welding area. To observe the welding area, the protective cover needs to be disassembled, which can easily cause the snaps on both sides of the protective cover to break. In addition, both the existing protective cover and the snaps are injection molded parts, which can lead to inconsistent fit due to dimensional errors. Therefore, in order to enhance the connection strength between the protective cover and the rotary transformer and facilitate the observation of the welding area, this hot-riveting protective cover was designed. Summary of the Invention

[0003] The purpose of this utility model is to provide a heat-riveting protective cover, on which a rivet insertion groove is formed. Using a hot-pressing device, pressure is applied to the rivet, causing it to deform from a slender shape to a short and thick shape. The diameter of the short and thick rivet is larger than the diameter of the circular hole, which further limits the rivet insertion groove and fixes the heat-riveting protective cover to the rotary transformer, thereby improving the stability and strength of the connection.

[0004] This utility model provides the following technical solution: a heat-riveting protective cover, which is installed on a rotary transformer. The heat-riveting protective cover includes a rivet insertion base and a PIN pin insertion base. The PIN pin insertion base is formed on one end face of the rivet insertion base. Rivet insertion grooves are formed on both ends of the rivet insertion base. A recessed plate is formed at the bottom of the rivet insertion groove. A circular hole is formed in the center of the recessed plate for inserting a rivet. A PIN pin observation hole is formed on the PIN pin insertion base.

[0005] Furthermore, a rivet insertion groove is also formed on the end face of the PIN pin insertion base away from the rivet insertion base. The three rivet insertion grooves are distributed in a triangle on the hot riveting protective cover. The triangular distribution of the rivet insertion grooves improves the connection stability between the hot riveting protective cover and the rotary transformer.

[0006] Furthermore, the height of the PIN pin insertion base is higher than that of the rivet pin insertion base, which is a foolproof design to avoid errors in the installation of the heat-riveted protective cover.

[0007] Furthermore, the rotary transformer is welded with PIN pins. The diameter of the PIN pin observation hole is larger than the diameter of the PIN pin. The number of PIN pin observation holes corresponds to the number of PIN pins. The PIN pin observation holes facilitate the observation of the welding area of ​​the PIN pins, ensuring that the PIN pins are firmly welded.

[0008] Furthermore, the PIN pin insertion base includes a top surface and a transition surface. The upper end of the transition surface is formed on the side of the top surface, and the lower end of the transition surface is formed on one end of the PIN pin insertion base. The other lower end of the transition surface has a downwardly extending shell. The PIN pin observation hole is opened on the top surface. Through the PIN pin insertion base formed by the transition surface and the top surface, the interior of the PIN pin insertion base is hollow, and the top surface of the PIN pin insertion base is located above the PIN pin, which facilitates the observation of the PIN pin.

[0009] Furthermore, symmetrically distributed side holes are provided on the bottom of both ends of the PIN pin insertion base. The side holes are located on the transition surface and the bottom of the housing. The side holes facilitate the gripping of the heat-riveted protective cover and also allow observation of the PIN pin soldering area, further ensuring the soldering is firm and stable.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] (1) Weld rivets onto the rotary transformer and form rivet insertion slots on the hot riveting protective cover. Use a hot pressing device to apply pressure to the rivets, causing them to deform from a slender shape to a short and thick shape. The diameter of the short and thick rivets is greater than the diameter of the round hole, which further limits the rivet insertion slots and fixes the hot riveting protective cover onto the rotary transformer, thus improving the stability and strength of the connection.

[0012] (2) A PIN observation hole is opened on the hot riveting protective cover to check the soldering area of ​​the PIN pin and ensure the soldering condition, making observation more convenient. At the same time, a side hole is opened because the side hole has a large area, which further improves the convenience of observing the soldering area. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 2 to 5. This utility model provides the following technical solution: A heat-riveting protective cover is mounted on a rotary transformer 1. A boss 11 is formed on the rotary transformer 1, and the shape of the boss 11 matches the shape of the heat-riveting protective cover 2 for installation and positioning. The heat-riveting protective cover 2 includes a rivet insertion base 22 and a pin insertion base 23. The pin insertion base 23 is formed on one end face of the rivet insertion base 22, and the rivet insertion base 22 wraps around one end face of the pin insertion base 23. Rivet insertion grooves 21 are formed on both ends of the rivet insertion base 22. A recessed plate 211 is formed at the bottom of the rivet insertion groove 21, and a circular hole is formed in the center of the recessed plate 211 for inserting a rivet 3. The rivet 3 is supported and limited after riveting. The rivet 3 and PIN pin 4 are welded on the boss 11. The rivet 3 is inserted into the rivet insertion groove 21. The rivet 3 is deformed by heat pressing through a pressure device, changing from a slender shape to a short and thick shape. The diameter of the short and thick rivet 3 is larger than the diameter of the round hole. The deformed rivet 3 is used to position the rivet insertion groove 21 and press the heat-riveted protective cover 2 onto the rotary transformer 1. The heat-riveted protective cover 2 is fixed, which improves the connection strength and stability between the heat-riveted protective cover 2 and the rotary transformer 1. The PIN pin insertion base 23 is provided with a PIN pin observation hole 24. The welding area of ​​the PIN pin is observed through the PIN pin observation hole 24 to ensure the welding quality.

[0022] As shown in Figure 4, a rivet insertion groove 21 is also formed on the end face of the PIN pin insertion base 23 away from the rivet insertion base 22. The three rivet insertion grooves 21 are distributed in a triangle on the hot riveting protective cover 2. The triangular distribution of rivets further improves the stability of the connection of the hot riveting protective cover 2 on the rotary transformer 1.

[0023] The height of the PIN pin insertion base 23 is higher than that of the rivet insertion base 22, which forms a foolproof design between the PIN pin insertion base 23 and the rivet insertion base 22 for the installation and positioning of the heat-riveted protective cover 2.

[0024] The rotary transformer is soldered with PIN pins 4. The diameter of the PIN pin observation hole 24 is larger than the diameter of the PIN pin 4. The number of PIN pin observation holes 24 corresponds to the number of PIN pins 4. The soldering area of ​​the PIN pin is observed through the PIN pin observation hole 24 to ensure the soldering condition of the PIN pin.

[0025] The PIN pin insertion base 23 includes a top surface 231 and a transition surface 232. The upper end of the transition surface 232 is formed on the side of the top surface 231, and the lower end of the transition surface 232 is formed on one end of the PIN pin insertion base 22. The other side of the transition surface 232 has a downwardly extending shell 233 formed at the lower end. The PIN pin observation hole 24 is opened on the top surface 231. Through the hollow PIN pin insertion base 23, it is convenient to observe the soldering area of ​​the PIN pin 4 through the PIN pin observation hole 24.

[0026] As shown in Figures 4 and 5, symmetrically distributed side holes 25 are provided on the bottom of both ends of the PIN pin insertion base 23. The side holes 25 are provided on the transition surface 232 and the bottom housing 233. The side holes 25 on both sides are on the same straight line, which makes it easy to observe the soldering area of ​​one side of the PIN pin 4 from the side of the side hole 25, ensuring the soldering status of the PIN pin 4. At the same time, the side holes 25 also make it easy for the grippers on the production line to grab the heat-riveted protective cover.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
