Description

Technical Field

[0001] This utility model relates to the field of spring contact technology, and in particular to a current-carrying spring contact that prevents loosening. Background Technology

[0002] Spring contact fingers are special mechanical connectors that combine elasticity and conductivity. The coils are elliptical and arranged at an angle. When compressed, each coil deforms independently, ensuring uniform load on all contact points and providing a nearly constant elastic force. They can carry strong current in a small space, have excellent current carrying capacity, and are suitable for high-voltage electrical equipment.

[0003] Traditional spring contacts are used to attach to equipment via their elasticity. However, this connection method relies on the elasticity of the spring contacts for traction. When displacement occurs at the electrical connection point, compressing the spring contacts, the spring contacts will deform, changing the direction of the elastic force and causing them to loosen.

[0004] Therefore, this application proposes an anti-loosening current-carrying spring contact finger to improve the stability of the spring contact finger connection. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a current-carrying contact finger that is not loosened, so as to solve the problem of easy detachment of the spring contact finger mentioned in the prior art.

[0006] To achieve the above and other related objectives, this utility model provides an anti-loosening current-carrying spring contact finger, comprising multiple anti-loosening connection mechanisms, wherein a first spring body and a second spring body are sleeved on the outer surface of the anti-loosening connection mechanism; Each of the anti-detachment connection mechanisms includes an arc-shaped constraint body. The upper and lower sides of the outer surface of the arc-shaped constraint body are provided with spring body constraint grooves. The first spring body and the second spring body are respectively disposed inside the spring body constraint grooves on the upper and lower sides, and the first spring body and the second spring body are limited by the spring body constraint grooves. All the aforementioned bow-shaped constraint bodies are assembled and installed on the electrical equipment under the elastic pressure of the first spring body and the second spring body.

[0007] Preferably, the first spring body and the second spring body have the same diameter, the same pitch, and the same material, and the outer surfaces of both the first spring body and the second spring body extend to the outside of the spring body constraint groove.

[0008] Preferably, the inner surface of all the bow-shaped constraint bodies is provided with anti-slip texture, which abuts against the surface of the electrical equipment.

[0009] Preferably, all of the bow-shaped constraint bodies have a positioning groove on their inner surface, and a traction spring is provided in the positioning groove.

[0010] Preferably, the positioning groove is located between the two spring body constraint grooves.

[0011] Preferably, a damping strip is provided at the vertical axis of the opening of the positioning groove, and the damping strip passes through the traction spring.

[0012] Preferably, the outer surface of the traction spring does not exceed the outer surface of the positioning groove.

[0013] Preferably, the bow-shaped constraint body is made of metal material, and the outer surface of the bow-shaped constraint body is provided with an electroplated layer.

[0014] As described above, the current-carrying spring contact finger for preventing loosening of this utility model has the following beneficial effects: 1. This utility model sets up multiple bow-shaped constraint bodies in a circumferential array, and sets two spring constraint grooves on the front of the bow-shaped constraint bodies to install and constrain the first spring body and the second spring body respectively. During use, the bow-shaped constraint bodies are fixed to the electrical equipment by the elastic pressure of the first spring body and the second spring body. When the bow-shaped constraint bodies, the first spring body and the second spring body are subjected to pressure and traction, the bow-shaped constraint bodies, the first spring body and the second spring body will provide mutual restraint through elasticity, so that the first spring body and the second spring body are difficult to fall off, thus achieving the effect of preventing loosening.

[0015] 2. This utility model provides a positioning groove on the back of the bow-shaped constraint body and a traction spring in the positioning groove. The traction spring is sleeved on the electrical equipment, and the cooperation between the traction spring and the positioning groove can limit the installation position of the bow-shaped constraint body and prevent it from shifting.

[0016] 3. This utility model provides a damping strip at the opening of the positioning groove and makes the damping strip pass vertically through the traction spring, so that the distance between two adjacent bow-shaped constraint bodies is similar, preventing the bow-shaped constraint bodies from sliding along the traction spring and changing the distance between the bow-shaped constraint bodies. At the same time, the damping strip can also improve the effect of the traction spring in limiting the position of the bow-shaped constraint bodies.

[0017] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value. Attached Figure Description

[0024] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0025] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0026] like Figure 1 and Figure 3As shown, this utility model provides an anti-loosening current-carrying spring contact finger, including multiple anti-loosening connection mechanisms 1. The outer surface of the anti-loosening connection mechanism 1 is fitted with a first spring body 2 and a second spring body 3. In use, the inner surfaces of all anti-loosening connection mechanisms 1 are attached to the outer surface of the internal electrical equipment by the elastic pressure of the first spring body 2 and the second spring body 3, while the surfaces of the first spring body 2 and the second spring body 3 are in contact with the interior of the external electrical equipment. When the two electrical equipment are displaced, the anti-loosening connection mechanism 1 can constrain the relative position of the first spring body 2 and the second spring body 3 and prevent the first spring body 2 and the second spring body 3 from loosening. At the same time, when the force on either the first spring body 2 or the second spring body 3 is uneven, the other component pulls the unevenly stressed component through the elastic force applied to the bow-shaped constraint body 11, thereby further preventing loosening. Moreover, by increasing or decreasing the number of anti-loosening connection mechanisms 1, the inner diameter of the anti-loosening connection mechanism 1 can be changed, thereby adapting to the electrodes of electrical equipment with different diameters. Specifically, such as Figure 4 As shown, each anti-detachment connection mechanism 1 includes an arc-shaped constraint body 11. Spring constraint grooves 12 are provided on the upper and lower sides of the outer surface of the arc-shaped constraint body 11. A first spring body 2 and a second spring body 3 are respectively disposed inside the spring constraint grooves 12 on the upper and lower sides, and are limited by the spring constraint grooves 12. All arc-shaped constraint bodies 11 are closed and installed on the electrical equipment under the elastic pressure of the first spring body 2 and the second spring body 3. When the electrical equipment is connected, the first spring body 2 and the second spring body 3 are limited between the two electrical devices by the spring constraint grooves 12 and are blocked by the upper and lower walls of the spring constraint grooves 12, preventing the first spring body 2 and the second spring body 3 from moving up and down. At this time, stable power can still be supplied between the two electrical devices through the arc-shaped constraint body 11, the first spring body 2, and the second spring body 3.

[0027] like Figure 2 As shown, in some embodiments, the first spring body 2 and the second spring body 3 of this invention have equal diameters, equal pitches, and are made of the same material. During use, the first spring body 2 and the second spring body 3 apply the same elastic pressure to the bow-shaped constraint body 11, which allows the bow-shaped constraint body 11 to be stably placed on the electrical component, and the traction forces received by the first spring body 2 and the second spring body 3 are equivalent. The outer surfaces of both the first spring body 2 and the second spring body 3 extend to the outside of the spring body constraint groove 12 for contact with the conductive electrodes of external electrical equipment, thereby realizing the electrical connection between the two electrical devices.

[0028] like Figure 1 and Figure 5As shown, in some embodiments, the inner surface of all the bow-shaped constraint bodies 11 of this utility model is provided with anti-slip textures 13. The anti-slip textures 13 abut against the surface of the electrical equipment to increase the friction between the bow-shaped constraint body 11 and the electrical equipment, so as to increase the constraint effect of the elastic pressure of the first spring body 2 and the second spring body 3 on fixing the position of the bow-shaped constraint body 11.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, in some embodiments, all the bow-shaped constraint bodies 11 of this invention are provided with positioning grooves 14 on their inner surfaces. A traction spring 4 is provided in the positioning groove 14. The traction spring 4 can provide outward elastic pressure to the bow-shaped constraint body 11. When the bow-shaped constraint body 11 is subjected to external pressure, the traction spring 4 will deform as a whole. The pressure of the deformation will be transmitted to the bow-shaped constraint body 11, so that the distance between all the bow-shaped constraint bodies 11 remains stable. Moreover, the traction spring 4 can be clamped to the electrical equipment by its own elastic pressure, and by cooperating with the positioning groove 14, it can prevent a single bow-shaped constraint body 11 from moving up and down.

[0030] like Figure 5 As shown, in some embodiments, the positioning groove 14 of this utility model is located between two spring body constraint grooves 12, so that when the bow-shaped constraint body 11 is constrained by the traction spring 4, all forces at the upper and lower ends of the bow-shaped constraint body 11 are the same.

[0031] like Figure 1 and Figure 5 In some embodiments, a damping strip 15 is provided at the vertical axis of the opening of the positioning groove 14 of this utility model. The damping strip 15 passes through the traction spring 4. Through the cooperation of the damping strip 15 and the traction spring 4, the horizontal position of the bow-shaped constraint body 11 can be further limited, so as to prevent the bow-shaped constraint body 11 from sliding along the axis of the traction spring 4, and the spacing between all bow-shaped constraint bodies 11 can be kept the same.

[0032] like Figure 2 As shown, in some embodiments, the outer surface of the traction spring 4 of this invention does not exceed the outer surface of the positioning groove 14, so that when the entire spring contact finger is installed, the inner wall surface of the bow-shaped constraint body 11 can fit tightly with the outer surface of the electrical equipment to improve the stability of power supply.

[0033] It is worth noting that the bow-shaped constraint 11 is made of metal to achieve electrical conductivity; the outer surface of the bow-shaped constraint 11 is provided with an electroplating layer, which can effectively improve the friction resistance, corrosion resistance and rust prevention of the bow-shaped constraint 11.

[0034] In summary, the anti-loosening current-carrying spring contact finger of this utility model is constructed by setting multiple bow-shaped constraint bodies 11 in a circumferential array, and providing two spring body constraint grooves 12 on the front of the bow-shaped constraint bodies 11 to respectively install and constrain the first spring body 2 and the second spring body 3. During use, the bow-shaped constraint bodies 11 are fixed to the electrical equipment by the elastic pressure of the first spring body 2 and the second spring body 3. When the bow-shaped constraint bodies 11, the first spring body 2 and the second spring body 3 are subjected to pressure and traction, the bow-shaped constraint bodies 11, the first spring body 2 and the second spring body 3 will provide mutual restraint through elasticity, thereby making it difficult for the first spring body 2 and the second spring body 3 to fall off, thus achieving the effect of preventing loosening.

[0035] This utility model provides a positioning groove 14 on the back of the bow-shaped constraint body 11, and a traction spring 4 is provided in the positioning groove 14. The traction spring 4 is sleeved on the electrical equipment, and the installation position of the bow-shaped constraint body 11 can be limited by the cooperation between the traction spring 4 and the positioning groove 14, so as to prevent the bow-shaped constraint body 11 from shifting.

[0036] This invention provides a damping strip 15 at the opening of the positioning groove 14, and the damping strip 15 passes vertically through the traction spring 4, thereby making the distance between two adjacent bow-shaped constraint bodies 11 similar, preventing the bow-shaped constraint bodies 11 from sliding along the traction spring 4 and changing the distance between the bow-shaped constraint bodies 11. At the same time, the damping strip 15 can also improve the effect of the traction spring 4 in limiting the position of the bow-shaped constraint bodies 11.

[0037] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0038] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
