Description

Technical Field

[0001] The utility model relates to the technical field of switch structures, in particular to a terminal connection structure for a rotary switch. Background Art

[0002] At present, most switches on the market realize the control of the on and off functions of the switch by pressing a button to control the opening / closing of the contacts of the terminals. The internal terminal structure generally has two contacts, one contact is fixed, and the other contact is controlled by the button to abut against or separate from the fixed contact, so as to realize the function of the switch. The arrangement of the terminal structure is relatively simple, and the current is also disconnected instantaneously after it is turned off, which has a relatively large impact on the use performance of the product.

[0003] Therefore, there is an urgent need to provide a terminal connection structure for a rotary switch to overcome the above-mentioned defects. Contents of the Utility Model

[0004] The main purpose of the utility model is to provide a terminal connection structure for a rotary switch, and the reasonable layout contributes to assisting the realization of the AC-DC integration function of the rotary switch, effectively improving the performance and service life of the product.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows: A terminal connection structure for a rotary switch, comprising a bottom shell, a pair of fixed terminal groups and a pair of elastic terminal groups, wherein the pair of fixed terminal groups are symmetrically distributed on the bottom shell, and each of the fixed terminal groups is provided with two conductive contacts A; the elastic terminal groups are symmetrically mounted on the bottom shell, and each of the elastic terminal groups is provided with an elastic conductive sheet whose two ends extend and guide toward one conductive contact A of the two fixed terminal groups respectively, and both ends of the elastic conductive sheet are provided with conductive contacts B that close / disconnect correspondingly with the conductive contacts A as the rotating shaft on the rotary switch rotates, so as to realize the switch function.

[0006] Preferably, each of the elastic conductive sheets is in a shape of a Chinese character "几".

[0007] Preferably, the middle part of the elastic conductive sheet is clamped and fixed on one side surface of a pin.

[0008] Preferably, a through hole through which the rotating shaft passes is formed in the middle part of the bottom shell.

[0009] Preferably, the two fixed terminal groups are mounted on the left and right sides of the through hole, and the two elastic terminal groups are mounted on the upper and lower sides of the through hole.

[0010] Preferably, each of the fixed terminal groups includes: pin two and conductive contact A, and a second fixing plate extends from both sides of each pin two, and the conductive contact A is fixed on the second fixing plate.

[0011] Preferably, the terminal connection structure for the rotary switch further includes: a switch that is snapped onto the bottom shell by a rotating shaft, and presses against a group of conductive contacts A and B located diagonally when rotated, or presses / releases each group of conductive contacts A and B.

[0012] Preferably, the switch is rectangular.

[0013] Preferably, each corner of the switch is designed to be chamfered.

[0014] This utility model discloses a terminal connection structure for a rotary switch. A pair of fixed terminal groups are mounted on the bottom shell, and a pair of axially symmetrical elastic terminal groups are installed between the fixed terminals. An elastic conductive sheet extends two conductive contacts B to a conductive contact A directly opposite the two fixed terminal groups. This allows the product to be installed on a rotary switch, and rotating the shaft enables the corresponding conductive contacts A and B to be switched on and off, thus achieving the switching function. This structure facilitates the integration of AC and DC buttons when used with AC / DC rotary control keys. Furthermore, the product's rational layout effectively improves switching performance when assisting in the switching function, thereby extending the product's lifespan. Attached Figure Description

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] It should be noted that when a component is referred to as "connected to" or "set on" another component, it can be directly on the other component or indirectly on that other component.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0023] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0024] Please see Figures 1 to 2 The terminal connection structure 100 for a rotary switch in this embodiment includes: a base shell 1, a pair of fixed terminal groups 2, and a pair of elastic terminal groups 3. The base shell 1 has a through hole 11 formed through a rotating shaft. The pair of fixed terminal groups 2 are symmetrically distributed on the base shell 1 and located on the left and right sides of the through hole 11. The pair of elastic terminal groups 3 are symmetrically mounted on the base shell 1 and located on the upper and lower sides of the through hole 11. Each fixed terminal group 2 is equipped with a double conductive contact A. Each elastic terminal group 3 is equipped with an elastic conductive sheet b1, with both ends extending and guided towards one of the conductive contacts A of the two fixed terminal groups 2. Each end of the elastic conductive sheet b1 is equipped with a conductive contact B that, according to the rotation of the rotating shaft on the rotary switch, corresponds to the conductive contact A and closes / opens to realize the switching function.

[0025] In a preferred embodiment, the middle part of the elastic conductive sheet b1 is snapped onto one side of the pin b0, and a straight line connecting the two elastic terminal groups 3 and the through hole 11 is perpendicular to another straight line connecting the two fixed terminal groups 2 and the through hole 11.

[0026] In a preferred embodiment, each fixed terminal group 2 includes: a second pin a1 and a conductive contact A. A second fixing piece a2 extends from both sides of each second pin a1, and a conductive contact A is mounted on each second fixing piece a2. Specifically, the two conductive contacts A of each fixed terminal group 2 correspond to one conductive contact B of each of the two elastic terminal groups 3. Under no external force, a gap is designed between each conductive contact A and its corresponding conductive contact B.

[0027] When this product is installed on a rotary switch, the rotary switch's shaft drives the switch to engage a diagonally opposite set of conductive contacts B. Rotating the switch until each conductive contact A connects to its corresponding conductive contact B, and then rotating the switch again, the first set of conducting conductive contacts A and B at the diagonal position disconnects, while the other diagonally opposite set of conductive contacts A and B remains conducting. This ensures circuit stability when the product is used in a rotary switch, improving product performance and extending its lifespan. The product's structure is also well-designed. Furthermore, the design facilitates the integration of AC and DC switching functions, resulting in a rational structural layout.

[0028] Please combine again Figure 3 The difference between this embodiment and the above embodiment is that this embodiment further includes: a switch 4 that is snapped onto the bottom shell 1 by a rotating shaft, and presses against a set of the conductive contacts A and B arranged diagonally when rotated, or that presses / releases each set of the conductive contacts A and B. Specifically, the switch 4 is cuboid in shape, and all four apex corners are designed to be chamfered.

[0029] In the off state, the two ends of the switch 4 along its length abut against the elastic conductive sheets b1 of the two elastic terminal groups 3. When the switch 4 is rotated, a set of diagonally opposite conductive contacts A and B located on one diagonal line are connected, while the other diagonal conductive contacts A and B are disconnected. When the switch 4 is rotated to face the two fixed terminal groups 2 along its length, each conductive contact A connects to its corresponding conductive contact B, and the product achieves the switch-on function. Upon further rotation, the first set of conductive contacts A and B that were connected disconnects, while the other diagonal conductive contacts A and B connect.

[0030] This structural design enables the product to achieve the function of rotating and conducting when used as a rotary switch, thus facilitating the integration of AC and DC power. Simultaneously, during rotation, a set of diagonally opposite conductive contacts A and B remain conductive, effectively improving the stability of circuit performance during use and consequently extending the product's lifespan.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
