Description

Technical Field

[0001] The utility model relates to the technical field of sensor manufacturing, in particular to a rotating transformer skeleton structure. Background Art

[0002] The reluctance rotary transformer is a type of signal motor, mainly used as a sensor to measure speed, angle, and position. Due to its simple structure and good stability, the reluctance rotary transformer has a good application in new energy vehicles. With the continuous development of new energy vehicles, the requirements for the threading method and reliability of the threading of the rotary transformer are more stringent.

[0003] Chinese patent document CN209233671 U discloses a rotating transformer skeleton, including: a skeleton body; a wire clamping mechanism, the wire clamping mechanism is arranged on the skeleton body; wherein the wire clamping mechanism includes: a base, the base is arranged on a magnetic yoke; a wire clamping plate, the wire clamping plate is arranged on the base, and a wire clamping hole is arranged on the wire clamping plate; a threading plate, the threading plate is arranged on the base, and a threading hole is arranged on the threading plate; the wire clamping hole corresponds to the threading hole. Compared with the prior art, the rotating transformer skeleton of the utility model has the following advantages: the wire clamp and threading hole structure of the insulating skeleton realizes the radial threading method of the product; the insulating skeleton has a simple structure, low manufacturing cost, and high reliability.

[0004] However, the part of the rotating transformer frame that fixes the signal line has no clamping ribs, and the friction is small, so the signal line is easy to fall off. At the same time, the surface of the signal line and the square part expand and contract due to heat or cold, which may cause the signal line to fall off, making the stability of the rotating transformer frame relatively low when in use. In addition, when the square part is covered with sealant, it may enter the circular part and then flow into the coil, making it more difficult to clean the rotating transformer frame. Utility Model Content

[0005] The main purpose of the utility model is to provide a rotating transformer skeleton structure, which can effectively solve the problems of relatively low stability and difficulty in cleaning during use.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A rotating transformer skeleton structure comprises a circular portion and a square portion, wherein a plurality of winding mounting portions are fixedly mounted in an annular array on the inner surface of the circular portion, a plurality of terminal posts are fixedly mounted on the side of the upper end of the square portion close to the circular portion, a plurality of jacks are provided on the side of the upper end of the square portion away from the circular portion, a plurality of vertically arranged clamping ribs are fixedly mounted on the side walls of the jacks, and a guide groove is provided on the upper end of the square portion.

[0008] Preferably, the outer surface of the square portion is sealed using a seal.

[0009] Preferably, the guide groove is located on a side of the insertion hole close to the circular portion.

[0010] Preferably, the terminal is connected to the stator winding on the outer surface of the winding mounting portion.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The skeleton structure of this rotary transformer adopts the design of clamping ribs. After the signal line is installed, the friction can be increased, making the signal line not easy to fall off. At the same time, the clamping ribs can increase the deformation space of the signal line. After the temperature change causes the skin and square part of the signal line to expand, the skin part can enter the gap of the clamping ribs, making the signal line more firmly fixed.

[0013] 2. The skeleton structure of the rotary transformer adopts a guide groove design, so that when the surface of the square part is covered with sealant, the guide groove can prevent the sealant from entering the circular part, so that the sealant can be cured in a predetermined direction.

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1 - Figure 4As shown, a rotating transformer skeleton structure includes a circular portion 1, a plurality of winding mounting portions 2 are fixedly installed in a circular array on the inner surface of the circular portion 1, the winding mounting portion 2 is a prior art, and the stator winding is wound on the outer surface of the winding mounting portion 2 when in use, a square portion 3 is also fixed on the outer surface of the circular portion 1, and a plurality of terminal posts 4 are also fixed on the upper end of the square portion 3 close to the circular portion 1. The terminal posts 4 are connected to the stator winding wound on the outer surface of the winding mounting portion 2 when in actual use, so as to further facilitate the connection with the signal line.

[0021] In addition, a plurality of sockets 5 are provided on the side of the upper end of the square portion 3 away from the circular portion 1. The sockets 5 are responsible for the installation of the signal line in actual use. A plurality of vertically arranged clamping ribs 6 are fixed to the side walls of the sockets 5. The plurality of clamping ribs 6 can clamp the signal line. At the same time, the clamping ribs 6 can increase the friction between the signal line and the clamping ribs 6 after the signal line is installed, so that the signal line is not easy to fall off. At the same time, the deformation space of the signal line is also increased. After the temperature change causes the skin of the signal line and the square portion 3 to expand, the skin part can enter the gap between the clamping ribs 6, thereby making the signal line more firmly fixed.

[0022] Specifically, a guide groove 7 is further provided on one side of the upper end of the square portion 3 close to the circular portion 1, and the outer surface of the square portion 3 is sealed with a sealant (such as silicone, latex, etc.). The design of the guide groove 7 can prevent the liquid resin glue from flowing onto the stator winding wound on the outer surface of the winding mounting portion 2, thereby causing the connecting wire to malfunction and affecting the normal operation of the device. At the same time, the sealant can prevent the signal lines from being connected during use, thereby causing a short circuit. The use of sealant for sealing can prevent oxidation, rust, etc. from occurring at the connection, thereby extending the service life of the device.

[0023] In addition, when the sealant is filled on the outer surface of the square portion 3, the guide groove 7 can prevent the sealant from entering the circular portion 1, allowing the sealant to solidify in a predetermined direction. At the same time, the guide groove 7, the insertion hole 5, and the clamping rib 6 can increase the friction between the seal and the square portion 3, allowing the sealant to be better adsorbed on the outer surface of the square portion 3, preventing the sealant from falling off from the outer surface of the square portion 3 after the device is vibrated, affecting the normal operation of the device.

[0024] The specific implementation of this embodiment is as follows: when the skeleton structure is in use, the stator winding is first wound on the outer surface of the winding mounting portion 2, and then the multiple stator windings are connected to the terminal 4, and then the signal line is fixed in the jack 5 and connected to the terminal 4. Due to the design of the clamping ribs 6, the signal line can be clamped. At the same time, the clamping ribs 6 can prevent the skeleton structure from expanding when heated and clamping off the connecting line, or shrinking when the skeleton structure is cooled and the signal line falls off, thereby affecting the normal operation of the skeleton structure;

[0025] After the signal line is installed, fill the outer surface of the square part 3 with sealant (from the side of the square part 3 away from the circular part 1 to the side close to the circular part 1). When the sealant flows into the guide groove 7, it will no longer flow to the side close to the circular part 1. It is only necessary to control the flow rate and filling thickness of the sealant to allow the sealant to seal the connecting line. At the same time, the guide groove 7 can prevent the sealant from flowing to the stator winding wound on the outer surface of the winding mounting part 2, thereby causing the stator winding to malfunction.

[0026] It should be noted that the specific installation method, circuit connection method and control method of the circular part 1, the stator winding and the square part 3 in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
