Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of silver contact structure, specifically relating to a silver contact structure for a thermostat switch assembly. Background Technology
[0002] The contacts in traditional thermostat switch assemblies are mostly made of copper or silver alloys, but under long-term high temperature and high current environments, they are prone to oxidation and wear, which affects the reliability and service life of the switch. Silver contact structures are gradually replacing traditional contacts due to their excellent overall performance. However, existing silver contact structures have certain drawbacks. For example, Chinese patent CN221726991 U discloses a silver-based composite electrical contact structure, which includes a detachably connected lower housing and an upper housing. The lower housing has a stationary contact and a moving contact. The moving contact includes a fixed end and a bent end. A pressing mechanism is slidably provided inside the upper housing. A rotating frame is rotatably connected to the pressing mechanism. A second spring is connected between the bottom of the rotating frame and the bent end of the moving contact. The bending end of the moving contact is connected or disconnected from the stationary contact by sliding the pressing mechanism. Although this device can realize the switching function, the connection structure is made of metal. However, metal is fatigue-prone. With the increase of bending times, the metal structure cannot return to its normal position after switching. Therefore, the metal electrode needs to be replaced regularly. However, this device requires complete disassembly to replace the metal electrode, making the replacement of the metal electrode difficult and inefficient. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1-5 As shown, this utility model provides the following technical solution:
[0021] A silver contact structure for a thermostat switch assembly includes a housing 1. The housing 1 includes a housing portion, one side of which is recessed to form a hollow cavity. A conductive portion for connecting two wires is installed inside the hollow cavity. The conductive portion includes a connecting electrode 12 and a metal electrode 16 for connecting the two wires. The connecting electrode 12 is located on one side of the metal electrode 16. A limiting block 15 is also fixedly connected inside the hollow cavity. The limiting block 15 is located between the metal electrode 16 and the connecting electrode 12. A pressing head 2 for pushing the metal electrode 16 is installed above the housing portion.
[0022] With the above technical solution, when personnel install the device, the housing is fixed. After the housing is fixed, the two wires that need to control the circuit are connected to the two connecting electrodes 12 and the metal electrode 16 respectively. The metal electrode 16 is squeezed by the pressing head 2, thereby deforming the metal electrode 16 and connecting it to the connecting electrodes 12, thus connecting the circuit. When personnel need to replace the metal electrode 16, they pull the metal electrode 16 to move it from the hollow cavity inside the housing to the outside of the housing. Then, the metal electrode 16 is inserted into the hollow cavity inside the housing. The limiting block 15 limits the metal electrode 16, thereby completing the installation of the metal electrode 16.
[0023] After the personnel install the metal electrode 16, in order to make the metal electrode 16 more stable, such as Figure 4 As shown, a limiting plate 18 is rotatably connected inside the hollow cavity, and a spring 19 is connected between the top of the limiting plate 18 and the hollow cavity.
[0024] In this embodiment, after the metal electrode 16 is installed, the spring 19 presses and pushes the limiting plate 18, causing the limiting plate 18 to contact the metal electrode 16, thus making the metal electrode 16 more secure after installation. When personnel need to replace the metal electrode 16, they press the limiting plate 18 to rotate until the limiting plate 18 separates from the metal electrode 16, and personnel can then remove the metal electrode 16 for replacement.
[0025] In order to shield the opening of the hollow cavity, such as Figures 1-4 As shown, a baffle 13 for shielding the hollow cavity is rotatably connected to one side of the shell portion, and the outer side of the baffle 13 is recessed to form a first groove 14.
[0026] In this embodiment, after the personnel install the metal electrode 16, they can rotate the baffle 13 to block the opening of the hollow cavity, thereby blocking the hollow cavity. When it is necessary to expose the hollow cavity, the baffle 13 is pulled by the first pull groove 14 to expose the hollow cavity.
[0027] Specifically, in one embodiment, regarding the aforementioned housing portion, such as Figures 1-4 As shown, the shell part includes an outer shell 11, and side plates 17 are fixedly connected to both sides of the outer shell 11 adjacent to the opening of the hollow cavity. Screws 110 are screwed onto the side plates 17.
[0028] In this embodiment, when a person needs a fixing device, the outer casing 11 is placed at the position where it needs to be fixed, and then the screw 110 is inserted into the side plate 17 and rotated. The screw 110 abuts against the side plate 17, thereby fixing the outer casing 11.
[0029] Furthermore, in this invention, to facilitate the connection between the metal electrode 16 and the connecting electrode 12, such as... Figures 1-3 As shown, two connectors 3 are fixedly connected to the outside of the outer casing 11 for connecting the metal electrode 16 and the connecting electrode 12, respectively. Connecting grooves 32 for connecting cables are formed on both connectors 3.
[0030] Specifically, in one embodiment, regarding the aforementioned connector 3, as... Figures 1-3 and Figure 5 As shown, the connector 3 includes a connector frame 31, a connector groove 32 formed on one side of the connector frame 31, a conductive plate 33 fixedly connected inside the connector groove 32, a top groove 34 formed by the top opening of the connector frame 31, a bendable top plate 35 fixedly connected to one side of the inner wall of the top groove 34, a plurality of protruding plates 37 formed by the bottom protrusion of the top plate 35, and a second pull groove 36 formed by the indentation of the top of the top plate 35.
[0031] In this embodiment, when it is necessary to connect the cable to the device, the top plate 35 is pulled by the second pull groove 36, causing the top plate 35 to rotate around the top groove 34, thereby separating the convex plate 37 from the conductive plate 33. Then, the wire is inserted into the connecting groove 32, the top plate 35 is released, the top plate 35 is reset, thereby driving the convex plate 37 to move, so that the convex plate 37 abuts against the wire onto the conductive plate 33, thus connecting the device with the guide.
[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
