Abstract
Description
Technical Field
[0001] This utility model relates to a relay structure. Background Technology
[0002] Existing relays are limited by the size of the glass tubes in the reed switches. Providing multiple reed switches increases the required space due to the number of glass tubes arranged side-by-side, thus hindering the overall size and space utilization of the relay. Especially when the relay is mounted on a circuit board, the increased size due to the side-by-side arrangement of glass tubes necessitates an increase in the area occupied on the circuit board, which is detrimental to the placement of electronic components and the utilization rate of the area. Summary of the Invention
[0003] This invention provides a relay structure that achieves a more efficient space utilization through the layered and staggered arrangement of reed switch components.
[0004] This utility model discloses a relay structure, including a frame, a coil, and a plurality of reed switches. The frame has a cavity extending along an axis. The coil is disposed in the frame and surrounds the cavity. The reed switches are arranged in layers within the cavity along the axis, with adjacent layers of reed switches staggered.
[0005] In an embodiment of this utility model, the orthographic projections of the magnetic reed switches of the two adjacent layers on the plane partially overlap each other, and the axis is the normal to the plane.
[0006] In the embodiments of this utility model, each of the above-mentioned reed switches includes a glass tube and at least two leads. The glass tube is elongated along the axis, and the at least two leads extend from opposite sides of the glass tube respectively. The orthographic projections of the glass tubes of the reed switches of the adjacent two layers on the plane partially overlap each other.
[0007] In an embodiment of the present invention, the aforementioned at least two leads include three leads, which extend from opposite sides of the glass tube back to back, and the glass tube is arranged in layers within the cavity along the axis.
[0008] In an embodiment of this utility model, the aforementioned lead-out foot extends to the insertion side of the frame.
[0009] In an embodiment of the present invention, the frame forms at least one step on the wall of the chamber to form at least two layers within the chamber.
[0010] In an embodiment of the present invention, at least two leads of each of the above-mentioned reed switches are moved out from opposite ends of the chamber, and the frame has a stop at one of the opposite ends to stop the glass tube and allow at least one lead to pass through.
[0011] Based on the above, since the relay structure includes a frame and multiple reed switches, the frame has a cavity extending along an axis, and these reed switches are arranged in layers within the cavity along this axis, with adjacent layers of reed switches staggered within the cavity. Accordingly, these reed switches are compactly arranged within the cavity through this layered, staggered configuration, achieving effective space utilization. Simultaneously, the overall structure of the relay is effectively reduced in size, allowing it to occupy a smaller area when mounted on a circuit board.
[0012] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below, and detailed descriptions are provided in conjunction with the accompanying drawings. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of a relay structure according to an embodiment of the present invention. Figure 2 yes Figure 1 A partial sectional view of the relay structure. Figure 3 yes Figure 2 An internal sectional view of the reed switch. Rectangular coordinates (XYZ) are provided here for component description. Please also refer to... Figures 1 to 3 In this embodiment, the relay structure 100 includes a frame 110, a coil 120, and a plurality of reed switches 130. The frame 110 has a chamber 112 extending along an axis (Z-axis). The coil 120 is disposed on the frame 110 and surrounds the chamber 112. The reed switches 130 are arranged in layers along the Z-axis within the chamber 112, with adjacent layers of reed switches 130 staggered.
[0020] like Figure 1 , Figure 2 As shown in detail, the frame 110 of this embodiment forms at least one step on the inner wall of its chamber 112, taking step 113 as an example. Therefore, step 113 substantially forms two layers of space along the Z-axis within the chamber 112. Meanwhile, the reed switch 130 of this embodiment includes glass tubes 132A and 132B and multiple leads 131. For ease of layered description, they are referred to as glass tubes 132A and 132B. Each glass tube 132A and 132B is elongated along the Z-axis in a capsule shape, and each glass tube 132A and 132B corresponds to two leads 131, extending from opposite sides of the glass tubes 132A and 132B along the Z-axis. Through the two layered spaces formed by the aforementioned step 113, the glass tubes 132A and 132B of adjacent reed switches 130 can achieve a layered, staggered configuration. Figure 2 As shown, taking planes L1 and L2 with different layers as an example, glass tube 132A is located in plane L1, while glass tube 132B is located in another layered plane L2.
[0021] Therefore, if any plane L1 or L2 is used as a reference, the orthographic projections of glass tubes 132A and 132B onto that plane L1 or L2 will partially overlap. Both planes L1 and L2 are parallel to the XY plane. In other words, the orthographic projections of the glass tubes 132A and 132B of the layered, staggered reed switch 130 onto the XY plane will partially overlap, and the Z-axis is the normal to the XY plane (which is also planes L1 and L2).
[0022] like Figure 2 As shown, the opening of the chamber 112 of the frame 110 is wider at one end (as shown in the image). Figure 2 The right end of chamber 112) and one end is smaller (such as...) Figure 2 The frame 110 has a stop 114 at the left end of the chamber 112, which provides the same stopping effect as the step 113. This allows the operator to insert glass tubes 132B and 132A into the chamber 112 sequentially, with the step 113 providing a stop for glass tube 132A, and the stop 114 providing a stop for glass tube 132B. This allows the glass tubes 132A and 132B to be arranged in layers along the Z-axis within the chamber 112. The stop 114 in the frame 110 still has through holes for the leads 131 to pass through, allowing the leads 131 of the reed switch 130 to extend smoothly from the opposite ends of the chamber 112 after extending back-to-back from the opposite sides of the glass tubes 132A and 132B.
[0023] For example Figure 3As shown, taking glass tube 132A as an example, the aforementioned two leads 131 form reed structures 131b spaced apart within glass tube 132A. When coil 120 conducts electricity and generates a magnetic field, the magnetic force drives the reed structures 131b to contact each other, thus achieving electrical conduction. The driving characteristics of the reed switch 130 are known in the prior art. Glass tube 132B also has the same structural composition, and will not be described further here.
[0024] In addition, please refer to Figure 1 After the lead-out foot 131 extends from the opening of the chamber 112, it further extends along the external structure of the frame 110 to the insertion side of the frame 110, such as... Figure 1 As shown on the right, a pin 131a is formed, and the frame 110 also has a pin 111 located on the same plug-in side. The coil 120 and the pin 111 of the frame 110 are substantially electrically connected, so that the pins 111 and 131a located on the plug-in side can be directly plugged into the circuit board (not shown here) to control the current passing through the coil 120 and whether the circuit containing the relay structure 100 is conducting.
[0025] Figure 4 This is a comparison diagram of the relay structure of this embodiment and the existing relay structure on the circuit board. The left side corresponds to the side view of the aforementioned relay structure 100, while the right side is a simplified illustration of the prior art using a non-layered misalignment method. Please refer to... Figure 4 In this embodiment, since the glass tubes 132A and 132B are arranged in a layered, staggered manner within the chamber 112, the required space (taking dimension A1 as an example) is reduced. Conversely, if the technical features of this invention are not adopted, but instead the glass tubes 132C are arranged in the same layer side by side (i.e., the glass tubes 132C are in the same position on the Z-axis) as in the prior art, the required space is significantly larger (the required XY area is larger). Taking dimension A2 as an example, dimension A2 is larger than dimension A1. Here, the glass tubes 132A, 132B, and 132C have the same size. When the relay structures of the above two different modes are configured on the circuit board 200, their occupied areas are also different. The area occupied by the two glass tubes 132C on the right is significantly larger than the area occupied by the glass tubes 132A and 132B on the left. Therefore, from Figure 4 It allows for a clearer understanding of the different effects produced by the two different configuration modes.
[0026] Figure 5 and Figure 6 These are schematic diagrams of some components of the relay structure according to different embodiments of this utility model. Please refer to them first. Figure 5Inheriting the aforementioned layered staggered technical features, in this embodiment, glass tubes 132D are located at the same position on the Z-axis (located in the same layer, i.e., both on plane L3), while glass tubes 132E are located at the same position on the Z-axis (located in another layer, i.e., both on plane L4). Similarly, the glass tubes 132D and 132E are layered along the Z-axis, with different layers being staggered. The number of glass tubes 132D or 132E in the same layer is not limited. In another embodiment not shown, the four glass tubes 132D and 132E of this embodiment may each be on a separate layer, dividing the space into four layers along the Z-axis.
[0027] Please refer to Figure 6 The four glass tubes 132G and 132F shown are also divided into two layers along the Z-axis, but unlike... Figure 5 The difference in the illustrated embodiment is that the two glass tubes 132G and 132F are arranged coaxially (along the same Y-axis), thus forming a shape as shown. Figure 6 As shown, the arrangement results in horizontal strips on the XY plane, but what remains the same is that the glass tubes 132G and 132F of different layers are still in a state of being interspersed with each other.
[0028] Figure 7 This is a reed switch adapted to another embodiment of this utility model. Please refer to... Figure 7 Unlike the aforementioned reed switch 130, the reed switch 230 in this embodiment includes a glass tube 232 and three leads 231 extending from the glass tube 232. Similar to the previous embodiment, the elastic metal spring is sealed within the glass tube 232, forming a normally open circuit (NO) contact and a normally closed circuit (NC) contact, allowing for opposite states when the relay is operated. As with the previous embodiment, when the relay provides multiple reed switches 230, the glass tubes 232 can be stacked as in the previous embodiment to achieve a compact spatial configuration. The arrangement of the glass tubes 232 within the frame in this embodiment is the same as in the previous embodiment and will not be repeated here.
[0029] In summary, in the above embodiments of this utility model, the relay structure includes a frame and a plurality of reed switches. The frame has a cavity extending along an axis, and the reed switches are arranged in layers within the cavity along this axis, with adjacent layers of reed switches staggered within the cavity. Furthermore, each reed switch includes a glass tube and leads extending from its opposite ends. To achieve a compact spatial configuration, the orthographic projections of adjacent layers of glass tubes on a plane partially overlap, thus allowing the glass tubes to be arranged in layers within the cavity along this axis, achieving a layered, staggered configuration. Accordingly, compared to side-by-side glass tubes, the glass tubes in this invention achieve effective space utilization. Simultaneously, the overall structure of the relay is effectively reduced in size, allowing it to occupy a smaller area when mounted on a circuit board.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
