Description

Technical Field

[0001] The utility model relates to the technical field of electric transmission equipment, in particular to an electric connector, electrically connected electric equipment and electrically driven rotating equipment. Background Art

[0002] In the prior art, carbon brushes or conductive slip rings equipped with carbon brushes are usually used to supply power or conduct electricity to devices on rotating shafts. In order to avoid the defect of poor contact between the carbon brush and the power-consuming electrode caused by the wear of the carbon brush, an elastic element, such as a spring, is often provided on the side of the carbon brush away from the power-consuming electrode and the spring is compressed. However, the rebound force of the spring increases the pressure between the carbon brush and the power-consuming electrode or the motor shaft, which easily causes greater wear.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0055] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0056] Embodiment 1

[0057] The utility model provides an electrical connector 100, such as Figure 1 to Figure 5 As shown, including:

[0058] A support frame, the support frame having a receiving gap;

[0059] Conductive fiber 2, the conductive fiber 2 is clamped in the accommodating gap and both ends of the conductive fiber 2 extend out of the accommodating gap;

[0060] A protruding portion 4 is fixedly disposed in the accommodating gap, one protruding portion 4 corresponds to one conductive fiber 2 , and part of the conductive fibers 2 surrounds a side of the protruding portion 4 that is away from the conductive fibers 2 .

[0061] When in use, the support frame is arranged on the stationary part on one side of the rotating part 10. When it is necessary to supply power to the electric load 14 arranged on the rotating part 10 (the electric load 14 rotates with the rotating part 10), it is necessary to make the end of the conductive fiber 2 contact with the electrode strip 11 on the rotating part 10 (the electrode strip 11 is preferably a ring structure, which is sleeved on the rotating part 10 and electrically connected to the electric load 14). The support frame is made of conductive material, and the external power supply is electrically connected to the support frame. The current is transmitted to the electric load 14 through the support frame, the conductive fiber 2 and the electrode strip 11 in sequence; when it is necessary to conduct electricity and ground the rotating part 10 itself, the conductive fiber 2 is made to contact with the rotating part 10 itself.

[0062] The electrical connector 100 provided by the utility model adopts a clamping method to fix the conductive fiber 2, abandoning the traditional gluing method. The clamping fastening method is more reliable. More importantly, a protrusion 4 is provided on one side of the conductive fiber 2 to limit the outward movement of the conductive fiber 2, so as to further improve the stability of the fixation of the conductive fiber 2, thereby improving the service life. Compared with the carbon brush structure, the utility model reduces the output resistance to the motor.

[0063] In the above embodiment, the support frame is used to fix and support the conductive fiber 2. Therefore, it only needs to have an accommodating gap and a protruding portion 4. It can be understood that the present invention does not limit the specific structure of the support frame, as long as it can achieve the purpose of clamping the conductive fiber 2 and restricting its outward movement.

[0064] However, in order to facilitate clamping, the present invention provides a support frame that can be implemented. In the embodiment of the present invention, the support frame includes a support plate 3 and a cover plate 1. The cover plate 1 is arranged on one side of the support plate 3 and there is a gap between the two. The gap between the cover plate 1 and the support plate 3 forms a receiving gap. When in use, after the conductive fiber 2 is placed in place, the conductive fiber 2 can be clamped by using the cover plate 1 and the support plate 3.

[0065] In some embodiments, a plurality of conductive fibers 2 are provided and the plurality of conductive fibers 2 are evenly arranged.

[0066] In some embodiments, the circumferential edge of the support plate 3 is provided with an outer ring 6 extending toward the cover plate 1 to cover the conductive fiber 2, thereby protecting the conductive fiber 2 and reducing the possibility of impurities falling into the accommodating gap.

[0067] In some embodiments, the cover plate 1 and the support plate 3 are connected by a fixing structure, and the fixing structure may be one of a rivet, an outer hoop, an anti-slip hook 8, an anti-slip ring and a welding structure.

[0068] Specifically, when an outer hoop is used, the outer hoop is made of metal material, and is put on the outer periphery of the cover plate 1 and the support plate 3 to tighten the two. Of course, the top and bottom of the outer hoop can also be bent toward the center of the cover plate 1 and the support plate 3 to wrap the edge structure of the cover plate 1 and the support plate 3, thereby achieving a better tightening effect.

[0069] When an anti-slip ring is used, the outer ring 6 extends beyond the plane where the surface of the cover plate 1 is located, and the portion that exceeds the plane is bent inward to limit the cover plate 1, forming a buckling surface 5, and the entire outer ring 6 forms an anti-slip ring structure to prevent the cover plate 1 from falling off. It can be understood that the outer ring 6 needs to be made of metal material, and the metal material can be bent. During the manufacturing process, the cover plate 1 is first set on the inner side of the outer ring 6, and then the edge of the outer ring 6 is machined to bend and press the cover plate 1.

[0070] When the anti-slip hook 8 is used, a plurality of anti-slip hooks 8 are provided, and the plurality of anti-slip hooks 8 are arranged at the edge of the support plate 3 along the circumference of the support plate 3, one end of the anti-slip hook 8 is fixedly connected to the support plate 3, and the other end extends toward the cover plate 1 to exceed the end surface of the cover plate 1 and then bends toward the center of the cover plate 1. Similar to the outer ring 6, the anti-slip hook 8 needs to be placed in the outer ring 6 before being machined to be bent and pressed against the outer surface of the cover plate 1. In a preferred embodiment, the plurality of anti-slip hooks 8 are evenly arranged along the circumference.

[0071] In addition, if Figure 6 to Figure 9 As shown, the anti-slip hook 8 can also be used in combination with the outer ring 6. It can be understood that in this solution, the outer ring 6 does not need to extend beyond the plane where the outer surface of the cover plate 1 is located. One end of the anti-slip hook 8 is fixedly connected to the outer ring 6, preferably as an integral structure, and the other end extends toward the center of the cover plate 1 to hook the cover plate 1 to prevent it from falling off.

[0072] In some embodiments, the raised portion 4 is fixedly disposed on a side of the cover plate 1 facing the support plate 3 or a side of the support plate 3 facing the cover plate 1 .

[0073] In the present embodiment, there are many ways of setting the raised portion 4 in the prior art, and the present invention can adopt any one of them. However, in order to make the entire component lightweight, in the present embodiment, the raised portion 4 is preferably stamped. For example, by stamping on one side of the cover plate 1, a groove can be formed on one side, and the above-mentioned raised portion 4 structure is formed on the other side. Therefore, there is no need to additionally set up a solid block to serve as the raised portion 4 structure, thereby achieving the purpose of lightweighting.

[0074] All the above embodiments are provided with only one layer of conductive fibers 2. However, when the required voltage is large, it is necessary to provide multiple layers of conductive fibers 2 along the axial direction of the product, such as Figure 10-11As shown, therefore, in the embodiment of the utility model, a plurality of cover plates 1 are provided, and the plurality of cover plates 1 are sequentially stacked on one side of the support plate 3, and conductive fibers 2 are also sandwiched between any two adjacent cover plates 1. Preferably, a convex portion 4 is stamped on each cover plate 1, so that each conductive fiber 2 in each layer of conductive fibers 2 is pulled by the convex portion 4, so as to prevent the conductive fibers 2 from being pulled out of the support frame and damaged when subjected to external force.

[0075] Considering that the conductive fiber 2 extending from the support frame may be warped when squeezed, which may easily lead to the production of defective products, in order to solve the above problem, in the embodiment of the utility model, the support plate 3 and the cover plate 1 are both annular plates, and the surface of the support plate 3 facing the cover plate 1 is divided into an inner annular surface 7 and an outer annular surface 6 from the inside to the outside, the inner annular surface 7 and the outer annular surface 6 are coaxial, the outer annular surface 6 is sleeved on the outer side of the columnar structure where the inner annular surface 7 is located, the inner annular surface 7 is located on the side of the outer annular surface 6 away from the cover plate 1, and the spacing between the inner annular surface 7 and the cover plate 1 is greater than the cross-sectional size of the conductive fiber 2. And the spacing is not easy to be too large, preferably slightly larger than the width size or radial size of the conductive fiber 2, thereby, the gap between the inner annular surface 7 and the cover plate 1 can play a certain limiting role on the conductive fiber 2 without squeezing the conductive fiber 2, thereby improving the yield rate during production. It can be understood that the good product described in this part means that the end of the conductive fiber will not be far away from the originally set position due to warping.

[0076] In some embodiments, the end of each conductive fiber 2 is located on the same annular trajectory, which may be a circular ring, a square ring, etc. The specific annular structure needs to be determined according to the shape of the rotating component 10 or the electrode strip 11, so that each conductive fiber 2 has the same contact state with the rotating component 10 or the annular electrode strip 11, thereby improving the stability of the current.

[0077] In some embodiments, the conductive fibers 2 are a cluster structure formed by bundling a plurality of single fibers, and the ends of the plurality of fibers in each conductive fiber 2 are flush.

[0078] In some embodiments, positioning holes 9 are provided on both the support plate 3 and the cover plate 1, and the positioning holes 9 on the support plate 3 and the positioning holes 9 on the cover plate 1 are provided one by one, so as to facilitate the relative positioning of the two during assembly processing. Preferably, a plurality of positioning holes 9 are provided along the circumference.

[0079] In some embodiments, the conductive fiber 2 is carbon fiber, metal fiber, polymer conductive fiber 2 or fiber mixed with metal and polymer materials, and the diameter of the fiber is 5-2000 microns. The above fibers have good wear resistance and long service life.

[0080] Embodiment 2

[0081] This embodiment provides an electrically connected electrical device, such as Figure 12 to Figure 15 As shown, including:

[0082] Electric drive rotating equipment, the rotating part 10 in the electric drive rotating equipment needs to be powered by a power source or the electricity is led out to the ground;

[0083] The electrical connector 100 includes a support frame having a receiving gap;

[0084] Conductive fiber 2, the conductive fiber 2 is clamped in the accommodating gap and both ends extend out of the accommodating gap; a protrusion 4 is fixedly arranged in the accommodating gap, one protrusion 4 corresponds to one conductive fiber 2, and part of the conductive fiber 2 surrounds the side of the protrusion 4 away from the conductive fiber 2;

[0085] The support frame is fixed to the stationary part of the electrically driven rotating device and is electrically connected to a power source or ground; the end of the conductive fiber 2 is in contact with the rotating component 10 or the electrode strip 11 on the rotating component 10 .

[0086] When in use, the support frame is arranged on the stationary part on one side of the rotating part 10. When it is necessary to supply power to the electric load 14 arranged on the rotating part 10 (the electric load 14 rotates with the rotating part 10), it is necessary to make the end of the conductive fiber 2 contact the electrode strip 11 on the rotating part 10 (the electrode strip 11 is preferably a ring structure, which is sleeved on the rotating part 10 and electrically connected to the electric load 14). The support frame is made of conductive material, and the external power supply is electrically connected to the support frame. The current is transmitted to the electric load 14 through the support frame, the conductive fiber 2 and the electrode strip 11 in sequence. This embodiment does not limit the number of electrical connectors 100. It can be understood that the number of electrical connectors 100 is determined according to the number of electrodes, and can be multiple, for example, two, three, four, etc. When two electrical connectors 100 are provided, the two electrical connectors 100 can be provided on the rotating part 10 on the same side of the electric load 14, or they can be provided on the rotating part 10 on both sides of the electric load 14.

[0087] The rotating part 10 (working shaft) in this embodiment needs to be insulated from the bearing or the bearing and the housing. A ceramic ball bearing can be used for insulation or an insulating shaft can be used. A non-conductive insulating coupling is required to connect the rotating shaft that provides power to the working shaft. During operation, the electrical connector 100 is inactive and is only connected to the power source, which can be AC ​​or DC, or a path can be added to connect to 380V power. The type of the electrical load 14 can be a light-emitting lamp, a heating wire, or a device with a single-chip microcomputer.

[0088] When the rotating member 10 itself needs to be electrically conductive and grounded, the conductive fibers 2 can be brought into contact with the rotating member 10 itself.

[0089] The electrically connected electrical equipment provided by the utility model adopts a clamping method to fix the conductive fiber 2, abandoning the traditional gluing method. The clamping fastening method is more reliable. More importantly, a protrusion 4 is provided on one side of the conductive fiber 2 to limit the outward movement of the conductive fiber 2, so as to further improve the stability of the fixation of the conductive fiber 2, thereby improving the service life. Compared with the carbon brush structure, the utility model reduces the output resistance to the motor.

[0090] In this embodiment, the support frame is used to fix and support the conductive fiber 2. Therefore, it only needs to have an accommodating gap and a protruding portion 4. It can be understood that the present invention does not limit the specific structure of the support frame, as long as it can achieve the purpose of clamping the conductive fiber 2 and restricting its outward movement.

[0091] However, in order to facilitate clamping, the present invention provides a support frame that can be implemented. In the embodiment of the present invention, the support frame includes a support plate 3 and a cover plate 1. The cover plate 1 is arranged on one side of the support plate 3 and there is a gap between the two. The gap between the cover plate 1 and the support plate 3 forms a receiving gap. When in use, after the conductive fiber 2 is placed in place, the conductive fiber 2 can be clamped by using the cover plate 1 and the support plate 3.

[0092] In some embodiments, the cover plate 1 and the support plate 3 are connected by a fixing structure, and the fixing structure may be one of a rivet, an outer hoop, an anti-slip hook 8, an anti-slip ring and a welding structure.

[0093] Specifically, when an outer hoop is used, the outer hoop is made of metal material, and is put on the outer periphery of the cover plate 1 and the support plate 3 to tighten the two. Of course, the top and bottom of the outer hoop can also be bent toward the center of the cover plate 1 and the support plate 3 to wrap the edge structure of the cover plate 1 and the support plate 3, thereby achieving a better tightening effect.

[0094] When an anti-slip ring is used, the outer ring 6 extends beyond the plane where the surface of the cover plate 1 is located, and the portion that exceeds the plane is bent inward to limit the cover plate 1, forming a buckling surface 5, and the entire outer ring 6 forms an anti-slip ring structure to prevent the cover plate 1 from falling off. It can be understood that the outer ring 6 needs to be made of metal material, and the metal material can be bent. During the manufacturing process, the cover plate 1 is first set on the inner side of the outer ring 6, and then the edge of the outer ring 6 is machined to bend and press the cover plate 1.

[0095] When the anti-slip hook 8 is used, a plurality of anti-slip hooks 8 are provided, and the plurality of anti-slip hooks 8 are arranged at the edge of the support plate 3 along the circumference of the support plate 3, one end of the anti-slip hook 8 is fixedly connected to the support plate 3, and the other end extends toward the cover plate 1 to exceed the end surface of the cover plate 1 and then bends toward the center of the cover plate 1. Similar to the outer ring 6, the anti-slip hook 8 needs to be placed in the outer ring 6 before being machined to be bent and pressed against the outer surface of the cover plate 1. In a preferred embodiment, the plurality of anti-slip hooks 8 are evenly arranged along the circumference.

[0096] In addition, the anti-slip hook 8 can also be used in combination with the outer ring 6. It can be understood that in this solution, the outer ring 6 does not need to extend beyond the plane where the outer surface of the cover plate 1 is located. One end of the anti-slip hook 8 is fixedly connected to the outer ring 6, preferably an integrated structure, and the other end extends toward the center of the cover plate 1 to hook the cover plate 1 to prevent it from falling off.

[0097] All the above embodiments are provided with only one layer of conductive fibers 2. However, when the required voltage is large, it is necessary to provide multiple layers of conductive fibers 2 along the axial direction of the product, such as Figure 10-11 As shown, therefore, in the embodiment of the utility model, a plurality of cover plates 1 are provided, and the plurality of cover plates 1 are sequentially stacked on one side of the support plate 3, and conductive fibers 2 are also sandwiched between any two adjacent cover plates 1. Preferably, a convex portion 4 is stamped on each cover plate 1, so that each conductive fiber 2 in each layer of conductive fibers 2 is pulled by the convex portion 4, so as to prevent the conductive fibers 2 from being pulled out of the support frame and damaged when subjected to external force.

[0099] In some embodiments, the conductive fiber 2 is a carbon fiber, a metal fiber, a polymer conductive fiber 2 or a fiber mixed with a metal and a polymer material, and the diameter of the fiber is 5-2000 microns. This facilitates the relative positioning of the two during assembly processing. Preferably, a plurality of positioning holes 9 are provided along the circumference.
