Abstract
Description
Technical Field
[0001] This invention relates to the field of relay technology, and in particular to a coil structure adapted to a seesaw-type armature and its high-frequency relay. Background Technology
[0002] A high-frequency relay is a type of relay used to switch high-frequency circuits. A typical high-frequency relay in the prior art includes a magnetic circuit part, a base part, and a moving spring part. The magnetic circuit part includes a coil, an armature, and a magnet. The coil is formed by injection molding a U-shaped iron core into a coil frame and then winding enameled wire around the winding window of the coil frame. The injection-molded coil frame encloses the middle part of the U-shaped iron core, with only the two ends of the U-shaped iron core exposed outside the coil frame. The end faces of the two ends of the U-shaped iron core are designated as the iron core pole faces. This type of high-frequency relay has a magnet welded and fixed to the U-shaped opening of a U-shaped iron core. The armature is supported by the magnet, and a protrusion or boss is set at the center of the armature to form a pivot point. This allows the two ends of the armature to engage with the pole face of the U-shaped iron core in a seesaw manner. In this coil structure of the high-frequency relay, the magnet needs to be welded. After welding, the flatness of the magnet directly affects the support of the armature pivot, resulting in the disadvantages of difficult welding process, poor flatness, and poor consistency. In addition, the welding of the magnet requires a portion of the winding space, resulting in a reduction in the winding space of the coil and a decrease in the attraction force. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a coil structure and its high-frequency relay adapted to a seesaw-type armature. Through structural improvement, it solves the problems of difficult welding process, poor flatness and poor consistency caused by welding the magnet and the iron core, and also solves the problem of the coil winding space being squeezed and the attraction force being reduced.
[0004] The technical solution adopted by this invention to solve its technical problem is: a coil structure adapted to a seesaw-type armature, comprising a U-shaped iron core, enameled wire, and a coil frame in which a portion of the U-shaped iron core is injection molded to form an integral part; the coil frame includes two flanges at both ends of the bottom wall of the U-shape of the U-shaped iron core, and a winding window for winding the enameled wire is formed between the two flanges; the ends of the two side walls of the U-shape of the U-shaped iron core are exposed on the corresponding flanges and form corresponding pole faces; the coil frame also includes a U-shaped iron core... The third flange at the middle position of the bottom wall of the U-shaped core divides the winding window into two sections; the third flange has a protrusion that serves as the rotation fulcrum of the armature assembly of the relay, so that the armature assembly can rotate around the protrusion, and the two ends of the armature in the armature assembly can respectively engage with the pole faces of the ends of the two side walls of the U-shape of the U-shaped core to perform a seesaw-like action; the third flange also has a wire passage groove that connects the enameled wires of the two winding windows together, and the bottom of the wire passage groove is flush with one wall surface of the bottom wall of the U-shape of the U-shaped core.
[0005] The wire passage groove is a through groove, and its through direction is the same as the length direction of the bottom wall of the U-shape of the U-shaped iron core; the wire passage groove is located on the outer side corresponding to the width of the bottom wall of the U-shape of the U-shaped iron core; the bottom of the wire passage groove is flush with one side of the thickness of the bottom wall of the U-shape of the U-shaped iron core.
[0006] The opening direction of the groove is the same as the protrusion direction of the protrusion.
[0007] There are two wire passage slots, which are respectively located on the two outer sides of the bottom wall of the U-shape corresponding to the width of the U-shaped iron core.
[0008] On both sides of the width of the bottom wall of the U-shaped iron core, at the position corresponding to the third flange, there is a notch. The plastic of the injection-molded third flange is filled into the notch to enhance the strength of the third flange.
[0009] The coil structure also includes a coil lead-out end, which is assembled into the flange of the coil frame by injection molding.
[0010] The two flanges and the third flange are each provided with an independent injection molding gate structure, so that the two flanges and the third flange are not connected to each other, thereby directly exposing the bottom wall of the U-shaped iron core in the two winding windows, and the enameled wire is directly wound on the bottom wall of the U-shaped iron core in the two winding windows.
[0011] In the U-shaped iron core, extension portions are provided at the ends of the two side walls of the U-shape and at positions near the corresponding ends, extending along the width and thickness directions, so that the polar surface area of the ends of the two side walls of the U-shape of the U-shaped iron core is greater than the cross-sectional area of the bottom wall of the U-shape of the U-shaped iron core.
[0012] The coil leads are four in number and are assembled in two flanges by injection molding. Each coil lead includes a winding lead exposed on one side of the corresponding flange and a lead exposed on the other side of the corresponding flange. The lead is provided with a protrusion that is pre-positioned and interference-fitted with the corresponding slot of the relay base.
[0013] A high-frequency relay includes a magnetic circuit portion, a base portion, and a moving spring portion. The magnetic circuit portion includes an armature assembly and a coil as described above. The base portion includes a base and a stationary spring portion integrated onto the base by injection molding. The stationary spring portion includes a stationary spring sheet and a contact point for contacting the moving spring portion. The moving spring portion is movably mounted in the base and corresponds to and cooperates with the stationary spring portion. The coil is mounted on the base. The armature assembly includes an armature and a magnet stacked and fixed together. The two sides of the middle of the armature assembly are respectively provided with rotating shafts that cooperate with the base portion. The upper end of the middle of the armature assembly abuts against the protrusion of the third flange of the coil frame. The armature assembly also cooperates with the moving spring portion to drive the moving spring portion to move when the coil is working.
[0014] In the armature assembly, the magnet is located on top and the armature is located below. The upper middle end of the magnet abuts against the protrusion of the third flange of the coil frame, and the surface of the magnet is provided with a protective layer. The rotating shaft is located on both sides of the width of the armature.
[0015] The base is provided with a slot, and the lead of the coil lead is inserted into the slot of the base. The protrusion of the lead and the slot of the base are interference fit.
[0016] The base portion also includes an upper grounding shield and a lower grounding shield. The lower grounding shield is integrated into the base by injection molding. The upper grounding shield is mounted on the base and located below the magnetic circuit portion. The two end flanges of the coil frame are also provided with support feet integrally formed with the coil frame by injection molding. The support feet of the coil frame rest on the upper grounding shield and are fixed by adhesive dispensing.
[0017] In the base, a glue storage tank surrounded by a glue separator is provided at the glue dispensing position corresponding to the support foot and the upper grounding shield to prevent glue from flowing into the contact area; the upper grounding shield rests on the top surface of the glue separator.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. This invention employs a coil frame that includes a third flange formed in the middle of the bottom wall of the U-shaped iron core, dividing the winding window into two segments. The third flange has a protruding portion that serves as a rotation fulcrum for the armature assembly of the relay. This allows the armature assembly to rotate around the protruding portion, enabling the two ends of the armature in the armature assembly to engage with the pole faces of the two side walls of the U-shaped iron core, respectively, to perform a seesaw-like action. This structure of the invention utilizes the superior precision of integrated injection molding compared to component assembly structures, solving the problems of difficult welding processes, poor flatness, and poor consistency caused by welding the magnet to the iron core.
[0020] 2. This invention employs a third flange and a wire-passing groove to connect the enameled wires of the two winding windows. The bottom of the wire-passing groove is flush with one wall of the U-shaped bottom wall of the U-shaped iron core. Furthermore, two wire-passing grooves are provided, each located on one of the outer sides corresponding to the width of the U-shaped bottom wall of the U-shaped iron core. This structure, by designing the bottom of the wire-passing groove to be flush with one wall of the U-shaped bottom wall of the U-shaped iron core, avoids the drawback of the enameled wires rubbing against each other and breaking at the crossing points of the wire-passing groove. If they are not flush, the enameled wires will rub against each other once per turn of winding, easily causing breakage at the contact friction point. By providing two wire-passing grooves, it can be applied to both single-coil monostable winding and double-coil magnetically held winding.
[0021] 3. This invention employs an independently injection-molded gate structure for both the two flanges and the third flange, ensuring that the two flanges and the third flange are not connected to each other. This allows the bottom wall of the U-shaped iron core in the two winding windows to be directly exposed, and the enameled wire to be directly wound around the bottom wall of the U-shaped iron core in the two winding windows. Furthermore, the U-shaped iron core includes extensions extending along the width and thickness directions at the ends of the two side walls of the U-shape and near the corresponding ends, ensuring that the pole surface area of the ends of the two side walls of the U-shape is larger than the cross-sectional area of the bottom wall of the U-shape. This structure of the invention, by directly winding the enameled wire onto the iron core, compensates for the reduced winding space caused by the third flange occupying the winding space. Additionally, by increasing the pole surface area to increase the coil attraction, it further compensates for the reduced winding space caused by the third flange occupying the winding space.

[0037] Example
[0038] See Figures 1 to 7As shown, the present invention discloses a coil structure adapted to a seesaw-type armature. The coil structure 10 includes a U-shaped iron core 2, enameled wire 1, and a coil frame 4 in which a portion of the U-shaped iron core 2 is injection molded to form an integral part. The coil frame 4 includes two flanges 41 at both ends of the bottom wall 21 of the U-shape of the U-shaped iron core 2, and a winding window for winding the enameled wire is formed between the two flanges 41. The ends 221 of the two side walls 22 of the U-shape of the U-shaped iron core 2 are exposed on the corresponding flanges 41 and form corresponding pole surfaces 222. The coil frame 4 also includes a coil formed on the bottom wall 21 of the U-shape of the U-shaped iron core 2. The third flange 42 at the middle position divides the winding window into two sections; the third flange 42 is provided with a protrusion 421 for serving as the rotation fulcrum of the armature assembly of the relay, so that the armature assembly can use the protrusion 421 as the rotation fulcrum, so that the two ends of the armature in the armature assembly can respectively cooperate with the pole surfaces 222 of the ends of the two side walls 22 of the U-shape of the U-shaped iron core 2 to perform a seesaw-like action; the third flange 42 is also provided with a wire groove 422 for connecting the enameled wire 1 of the two winding windows together, and the bottom of the wire groove 422 is flush with one wall surface of the bottom wall 21 of the U-shape of the U-shaped iron core 2.
[0039] In this embodiment, the wire passage groove 422 is a through groove, and its through direction is the same as the length direction of the bottom wall 21 of the U-shape of the U-shaped iron core 2; the wire passage groove 421 is located on the outer side corresponding to the width of the bottom wall of the U-shape of the U-shaped iron core 2; the bottom of the wire passage groove 422 is at the same thickness as the bottom wall 21 of the U-shape of the U-shaped iron core 2 (e.g., Figure 2 The bottom surface of the U-shaped iron core 2 is flush with the bottom surface of the U-shaped bottom wall 21. The bottom of the wire groove 422 is arc-shaped, and the lowest point of the arc is flush with the thickness of one side of the bottom wall 21 of the U-shaped iron core 2.
[0040] In this embodiment, the opening direction of the groove 422 is the same as the protrusion direction of the protrusion 421.
[0041] In this embodiment, there are two wire passage slots 422, which are respectively located on the two outer sides of the bottom wall 21 of the U-shape corresponding to the width of the U-shaped iron core 2.
[0042] In this embodiment, on both sides of the width of the U-shaped bottom wall 21 of the U-shaped iron core 2, at positions corresponding to the third flange 42, a notch 211 is provided. The plastic of the injection-molded third flange 42 fills the notch 211 to enhance the strength of the third flange. This structure can prevent the plastic part of the third flange 42 from being too thin due to the presence of a through groove, thus enhancing the strength of the third flange 42. In addition, injecting the notch into the injection molded part can improve the injection molding effect.
[0043] In this embodiment, the coil structure further includes a coil lead-out end 3, which is assembled in the flange 41 of the coil frame 3 by injection molding.
[0044] In this embodiment, the two flanges 41 and the third flange 42 are respectively provided with gate structures 43 formed by independent injection molding, so that the two flanges 41 and the third flange 42 are not connected to each other, thereby allowing the U-shaped bottom wall portion 211 of the U-shaped iron core 2 in the two winding windows to be directly exposed, and the enameled wire 1 is directly wound on the U-shaped bottom wall portion 211 of the U-shaped iron core 2 in the two winding windows.
[0045] In this embodiment, in the U-shaped iron core 2, an extension portion 223 is provided at the ends 221 of the two side walls of the U-shape and at the positions near the corresponding ends, extending along the width and thickness directions, so that the area of the pole surface 222 at the ends of the two side walls 33 of the U-shape of the U-shaped iron core 2 is greater than the cross-sectional area of the bottom wall 21 of the U-shape of the U-shaped iron core.
[0046] In this embodiment, there are four coil lead-out ends 3, which are respectively assembled in two flanges 41 by injection molding. Each coil lead-out end 3 includes a winding foot 31 exposed on one side of the corresponding flange 41 and a lead-out foot 32 exposed on the other side of the corresponding flange 41. The lead-out foot 32 is provided with a protrusion 321 that is pre-positioned and interference-fitted with the corresponding slot of the relay base.
[0047] See Figures 1 to 14 As shown, a high-frequency relay of the present invention includes a magnetic circuit portion, a base portion 5, and a moving spring portion 6; the magnetic circuit portion includes an armature assembly 7 and a coil 10 as described above; the base portion 5 includes a base 51 and a stationary spring portion integrated on the base by injection molding, the stationary spring portion including a stationary spring plate 521 and a contact point 522 for contacting the moving spring portion; the moving spring portion 6 is movably mounted in the base 51 and corresponds to and cooperates with the stationary spring portion; the moving spring portion 6 includes a bridge-type moving spring plate 61, a reaction spring plate 62, and an injection-molded part 63 that combines the bridge-type moving spring plate 61 and the reaction spring plate 62 into a single integral part by injection molding; the coil assembly... On the base 51, the armature assembly 7 includes an armature 71 and a magnet 72 stacked and fixed together. The two sides of the middle of the armature assembly 7 are respectively provided with rotating shafts 73 that cooperate with the base part 5. The upper end of the middle of the armature assembly 7 abuts against the protrusion 421 of the third flange 42 of the coil frame 4, so that the armature assembly 7 can use the protrusion 421 as a fulcrum for rotation, so that the two ends of the armature 71 can cooperate with the pole surfaces 222 of the ends 221 of the U-shaped side walls 22 of the U-shaped iron core 2 to perform a seesaw-like action. The armature assembly 7 also cooperates with the moving spring part 6 to drive the moving spring part 6 to move when the coil is working.
[0048] In this embodiment, in the armature assembly 7, the magnet 72 is disposed on the top and the armature 71 is disposed on the bottom. The upper middle end of the magnet 72 abuts against the protrusion 421 of the third flange 42 of the coil frame 4. The surface of the magnet 72 is provided with a protective layer. The rotating shaft 73 is disposed on both sides of the width of the armature 71.
[0049] In this embodiment, the base 51 is provided with a slot 511, and the lead-out pin 32 of the coil lead-out end 3 is inserted into the slot 511 of the base 51. The protrusion 321 of the lead-out pin 32 and the slot 511 of the base 51 are interference fit.
[0050] In this embodiment, the base portion 5 further includes an upper grounding shield 53 and a lower grounding shield 54. The lower grounding shield 54 is integrated into the base 51 by injection molding. The upper grounding shield 53 is installed in the groove 512 of the base 51 and is located below the magnetic circuit portion. The two end flanges 41 of the coil frame 4 are also provided with support feet 44 integrally formed with the coil frame by injection molding. The support feet 44 of the coil frame 4 rest on the upper grounding shield 53 and are fixed by adhesive dispensing.
[0051] In this embodiment, the base 51 is provided with an adhesive storage tank 56 surrounded by an adhesive barrier 55 at the position corresponding to the adhesive dispensing position of the support foot 44 and the upper grounding shield 53, so as to prevent adhesive from flowing into the contact area; the upper grounding shield 53 rests on the top surface of the adhesive barrier 55.
[0052] This invention discloses a coil structure adapted to a seesaw-type armature and its high-frequency relay. The coil frame 4 includes a third flange 42 formed in the middle of the bottom wall 21 of the U-shape of the U-shaped iron core 2, dividing the winding window into two segments. The third flange 42 has a protrusion 421 serving as a rotation fulcrum for the armature assembly 7 of the relay. This allows the armature assembly 7 to rotate around the protrusion 421, enabling both ends of the armature assembly 7 (specifically, both ends of the armature 71) to engage with the pole faces of the two side walls of the U-shape of the U-shaped iron core, thus performing a seesaw-like action. This structure of the invention utilizes the superior precision of integrated injection molding compared to component assembly structures, solving the problems of difficult welding processes, poor flatness, and poor consistency caused by welding the magnet to the iron core.
[0053] The present invention discloses a coil structure adapted to a seesaw-type armature and its high-frequency relay, which employs two flanges 41 and the third flange 42, each having an independently injection-molded gate structure 43, so that the two flanges 41 and the third flange 42 are not connected to each other, thereby directly exposing the bottom wall portion 211 of the U-shaped iron core 2 in the two winding windows, and the enameled wire 1 is directly wound on the bottom wall portion 211 of the U-shaped iron core 2 in the two winding windows; and in the U-shaped iron core 2, extension portions 223 are provided along the width and thickness directions at the ends 221 of the two side walls 22 of the U-shape and near the corresponding ends, so that the area of the pole surface 222 of the ends of the two side walls 22 of the U-shape of the U-shape of the U-shaped iron core 2 is larger than the cross-sectional area of the bottom wall 21 of the U-shape of the U-shaped iron core 2. This structure of the present invention, by directly winding enameled wire onto the iron core, can compensate for the effect caused by the third flange occupying the winding space, which reduces the winding space. In addition, by increasing the pole area to increase the coil attraction, it further compensates for the effect caused by the third flange occupying the winding space, which reduces the winding space.
