Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically a universal changeover switch. Background Technology

[0002] In existing technologies, such as those with publication numbers CN207651376U and CN217485317U, when the moving contact assembly is connected to the housing, the moving contact and the bracket in the moving contact assembly are both attached to the inner wall surface of the housing. Since there is no reliable limiting between the moving contact, the bracket, and the housing, when the spring is installed, the spring will bounce the bracket or the spring itself away during the pressing process. In addition, even if the moving contact assembly is assembled into the housing, once the housing is vibrated, the spring will bounce the bracket or itself away again, resulting in low assembly efficiency of the moving contact assembly and the housing. Utility Model Content

[0003] The purpose of this invention is to provide a universal changeover switch to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a universal changeover switch, comprising a middle section assembly, the middle section assembly comprising a housing, and the bottom surface of the housing being provided with a guide groove, a stationary contact and a moving contact assembly; the moving contact assembly comprising a moving contact, a bracket and a spring; wherein, the side of the bracket is further provided with a sliding groove, and the sliding groove is slidably engaged with a guide block provided on the side of the guide groove.

[0005] As a preferred technical solution of this utility model: the housing is further provided with a socket, and the stationary contact is connected to the socket.

[0006] As a preferred technical solution of this utility model: the middle part of the socket is further provided with a protrusion, and the stationary contact is fastened to the protrusion through a provided slot.

[0007] As a preferred technical solution of this utility model: a partition is also provided in the guide groove, and the bracket slides on the upper surface of the partition.

[0008] As a preferred technical solution of this utility model: one side of the bracket is provided with a first guide surface, and the other side of the bracket is provided with a second guide surface.

[0009] As a preferred technical solution of this utility model: the number of guide blocks is two, and the two guide blocks are symmetrically arranged on both sides of the guide groove.

[0010] As a preferred technical solution of this utility model, the bracket is secured to the moving contact via a provided slot.

[0011] As a preferred technical solution of this utility model: the slot is provided with a pin, and one end of the pin passes through the moving contact and is exposed on one side of the moving contact.

[0012] The beneficial effects of this utility model by adopting the above technical solution are: 1. The device uses the guide groove to guide the slide of the bracket, so that the moving contact and the stationary contact can make reliable and smooth contact. At the same time, when the moving contact component is assembled into the housing, the sliding groove on the bracket is connected to the guide block, so the bracket can be limited, thereby avoiding the phenomenon that the spring and the bracket are bounced away when the spring is installed or when the equipment is vibrated.

[0013] 2. Because the bracket will not easily move inside the housing due to the action of the slide and guide block, the bracket and spring can remain stably located inside the housing when the entire middle section assembly moves or is subjected to vibration, thus providing feasibility for the next step of automated assembly.

[0020] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. In the description of this utility model, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and 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, and therefore should not be construed as limiting this utility model.

[0021] Please see Figure 1-5 The present invention provides an embodiment of a universal changeover switch, comprising a middle section assembly 1, wherein the middle section assembly 1 includes a housing 10, and the bottom surface of the housing 10 is provided with a guide groove 11, a stationary contact 12 and a moving contact assembly 16; the moving contact assembly 16 includes a moving contact 14, a bracket 13 and a spring 15; wherein the side of the bracket 13 is also provided with a sliding groove 112, and the sliding groove 112 is slidably engaged with a guide block 19 provided on the side of the guide groove 11.

[0022] In summary, the device uses the guide groove 11 to guide the sliding of the bracket 13, thus enabling reliable and smooth contact between the moving contact 14 and the stationary contact 12. At the same time, when the moving contact assembly 16 is assembled into the housing 10, the sliding groove 112 on the bracket 13 is connected to the guide block 19, thus limiting the bracket 13 and preventing the spring 15 and the bracket 13 from being bounced off when the spring 15 is installed or when the device is vibrated.

[0023] In particular, because the bracket 13 does not easily move inside the housing 10 due to the action of the slide groove 112 and the guide block 19, the bracket 13 and the spring 15 can be stably located inside the housing 10 when the entire middle section assembly moves or is subjected to vibration. At the same time, the cooperation between the slide groove 112 and the guide block 19 can limit the assembly method of the bracket 13, that is, change the original two or three actions of selecting the direction into a single vertical pressing action, thus providing feasibility for the next step of automated assembly.

[0024] Furthermore, since the housing 10 is also provided with a socket 17, and the stationary contact 12 is connected to the socket 17, the stationary contact 12 only needs to be inserted during assembly, thus simplifying the assembly steps. Simultaneously, the socket 17 also has a protrusion 111 in the middle, and the stationary contact 12 is secured to the protrusion 111 via a slot 18. Therefore, the cooperation between the slot 18 and the protrusion 111 ensures that the stationary contact 12 can be assembled smoothly, and that its position is accurate and reliable after assembly.

[0025] Based on the above solution, a partition 110 is also provided in the guide groove 11, and the bracket 13 slides on the upper surface of the partition 110. Therefore, by using the partition 110 to support the bracket 13, the phenomenon of positional deviation of the bracket 13 due to the bracket 13 moving downwards towards the housing 10 can be avoided.

[0026] Furthermore, since one side of the bracket 13 is provided with a first guide surface 113 and the other side of the bracket 13 is provided with a second guide surface 115, the combination of the two guide surfaces can be used to guide the assembly of the devices. Specifically, when the cam is assembled, the first guide surface 113 can reduce the resistance during cam assembly, and when the spring 15 is installed, it can slide smoothly downwards along the second guide surface 115 to reduce the resistance experienced by the spring 15 during assembly.

[0027] Furthermore, since there are two guide blocks 19, and the two guide blocks 19 are symmetrically arranged on both sides of the guide groove 11, the two guide blocks 19 are used to ensure the directional movement of the bracket 13. At the same time, the guide blocks 19 on both sides can be used to lock in the slide groove 112 to further improve the stability of the bracket 13 after it is connected to the housing 10, thereby improving the shock resistance of the device.

[0028] At the same time, since the bracket 13 is secured to the moving contact 14 through the provided slot 114, the bracket 13 and the moving contact 14 can be stably and reliably combined.

[0029] Furthermore, the slot 114 is provided with a pin 116 inside, and one end of the pin 116 passes through the moving contact 14 and is exposed on one side of the moving contact 14.

[0030] Based on this, when the pin 116 is inserted into the moving contact 14, the slot 114 is locked onto the moving contact 14, thus making the connection between the moving contact 14 and the bracket 13 stable and reliable.

[0031] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
