Description

Technical Field

[0001] This invention relates to the field of relay technology, and in particular to a moving spring portion for high-frequency signal transmission and a high-frequency relay thereof. 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 section, a base section, and a moving spring section. The stationary spring section is integrated into the base section, forming the base itself. The magnetic circuit section is mounted on top of the base section. The armature in the magnetic circuit section has a seesaw structure and cooperates with the moving spring section installed in the base. The base has a groove. The moving spring section includes a moving spring assembly and a return spring. The moving spring assembly is mounted in the base via the return spring. When one end of the armature moves downwards, pressing down on the moving spring assembly, the moving spring assembly overcomes the elastic force of the return spring, causing the bridge-type moving spring in the moving spring assembly to move downwards in the groove, allowing the two ends of the bridge-type moving spring to contact the contact points on the two stationary springs. This completes the circuit connected to the two stationary springs. When one end of the armature moves upwards, the moving spring assembly, under the action of the elastic force of the return spring, moves the bridge-type moving spring in the moving spring assembly upwards in the groove, causing the two ends of the bridge-type moving spring to separate from the contact points on the two stationary springs. This disconnects the circuit connected to the two stationary springs. In existing technologies, the moving spring assembly and the reaction spring are two separate parts, resulting in a large number of parts in the moving spring section, poor assembly stability, low material utilization, and high manufacturing costs. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a moving spring part for high-frequency signal transmission and its high-frequency relay, which has the characteristics of fewer parts, good structural strength, good assembly stability, high material utilization and low manufacturing cost.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a moving spring part for high-frequency signal transmission, including a first sheet, a second sheet, and a plastic body in which the middle part of the first sheet and the second sheet are not connected to each other to form an integral structure by injection molding; the first sheet is set as a bridge-type moving spring of the moving spring part; the two ends of the second sheet are bent into downward protrusions to form a reaction spring of the moving spring part.

[0005] The first sheet and the second sheet are formed on the same strip by stamping; the first sheet is stamped at both ends to form the bridge-type moving spring; the second sheet is stamped and bent at both ends to form the reaction spring.

[0006] The plastic body is elongated and perpendicular to the first sheet on the same horizontal plane.

[0007] The plastic body has a protrusion on its surface for engaging with the armature portion of the relay.

[0008] The strip is rectangular in shape, and the first and second pieces are arranged side by side in the same direction along the length or width of the rectangle.

[0009] There are two first pieces and one second piece; in the side-by-side arrangement, the second piece is in the middle and the two first pieces are on both sides; the second piece and the plastic body form a cross-shaped structure.

[0010] The first piece consists of one piece, and the second piece consists of two pieces; in the side-by-side arrangement, the first piece is in the middle, and the two second pieces are on both sides; the two second pieces and the plastic body form an I-shaped structure.

[0011] The second piece is frame-shaped, and the plastic body fills a portion of the central through-hole of the frame-shaped second piece.

[0012] A high-frequency relay includes a magnetic circuit portion, a base portion, and the aforementioned moving spring portion; the magnetic circuit portion is mounted on the base portion; the base portion has a groove for fitting the moving spring portion into which it is inserted, the moving spring portion is inserted into the groove by the elastic characteristics of the reaction spring, and the bridge-type moving spring of the moving spring portion is limited between the contact point of the stationary spring of the base portion and the upper baffle; the armature portion of the magnetic circuit portion mates with the plastic body of the moving spring portion.

[0013] The base portion has a groove with multiple support blocks, which form a cross-shaped or I-shaped groove that fits the plastic body of the moving spring portion and the second piece of the body.

[0014] The magnetic circuit section also includes a coil section that mates with the armature section; the coil section is mounted on the base section, and the armature section mates with the coil section in a seesaw manner.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] This invention utilizes a first sheet, a second sheet, and a plastic body formed by injection molding, with the middle portions of the first and second sheets not connected to each other, to create a single integral structure for the moving spring portion used for high-frequency signal transmission. The first sheet serves as a bridge-type moving spring within the moving spring portion; the second sheet, with its ends bent to form downward protrusions, constitutes a reaction spring within the moving spring portion. This structure of the invention offers advantages such as fewer components, higher structural strength, better assembly stability, higher material utilization, and lower manufacturing costs.

[0035] In this embodiment, there are two first sheet bodies 11 and one second sheet body 12; in the side-by-side arrangement, the one second sheet body 12 is in the middle, and the two first sheet bodies 11 are on both sides; the one second sheet body 12 and the plastic body 2 form a cross-shaped structure. After stamping, the moving spring part 3 contains two bridge-type moving spring sheets 4, one reaction spring sheet 5, and a plastic body 2 that is injection molded into an integral structure of the two bridge-type moving spring sheets 4 and the reaction spring sheet 5. Two protrusions 21 are provided on the plastic body 2 to cooperate with the armature part of the relay.

[0036] In this embodiment, the second sheet 12 is frame-shaped, and the plastic body 2 fills a portion of the central through hole 121 of the frame shape of the second sheet 12.

[0037] See Figures 1 to 11 As shown, a high-frequency relay of the present invention includes a magnetic circuit portion 6, a base portion 7, and the aforementioned moving spring portion 3. The base portion 7 includes a base 71, a stationary spring 72 containing a stationary contact 721, and an upper baffle 73, wherein the stationary spring 72 is embedded in the base 71 by injection molding. The magnetic circuit portion 6 is mounted on the base portion 7. The base portion 7 is provided with a groove 711 for fitting the moving spring portion 3, that is, the base 71 is provided with a groove 711 for fitting the moving spring portion 3. The moving spring portion 3 is fitted into the groove 711 by the elastic characteristics of the reaction spring 5, and the bridge-type moving spring 4 of the moving spring portion 3 is limited between the contact point 721 of the stationary spring of the base portion and the upper baffle 73. The armature portion 61 of the magnetic circuit portion 6 cooperates with the plastic body 2 of the moving spring portion 3.

[0038] In this embodiment, the groove 711 of the base portion 7 is provided with a plurality of support blocks 712, that is, the groove 711 of the base 71 is provided with a plurality of support blocks 712, and the plurality of support blocks 712 form a cross-shaped groove 713 adapted to the plastic body 2 of the moving spring portion 3 and the reaction spring 5.

[0039] In this embodiment, the upper baffle 73 is a whole grounding shield. The upper baffle 73 is installed in the groove 711 of the base 71.

This invention features a structure in which a moving spring (i.e., a bridge-type moving spring 4) and a springback mechanism (i.e., a reaction spring 5) are mounted on the same strip. The moving spring and the springback mechanism are oriented in the same direction, making full use of the scrap material between the moving spring strips to form a reaction spring structure. This structure is then injection molded together with the moving spring, reducing the number of assembly parts and improving material utilization. Because the moving spring and the springback mechanism are oriented in the same direction, the springback mechanism is planar after the strip is punched and injection molded. It is then bent using the space on both sides of the injection molded part (i.e., the plastic body 2) to form a springback mechanism with springback force. This invention has the advantages of fewer parts, better structural strength, better assembly stability, higher material utilization, and lower manufacturing cost.
