Description

Technical Field

[0001] The utility model relates to the technical field of single - pole single - throw switches, and specifically relates to a miniaturized modular single - pole single - throw switch. Background Technique

[0002] A knife - switch is a switch device mainly used for "isolating power sources, performing switching operations, and connecting and disconnecting small - current circuits" without an arc - extinguishing function. When the knife - switch is in the off position, there is an insulating distance that meets the specified requirements and an obvious disconnection mark between the contacts; when in the on position, it can carry the current under normal circuit conditions and the current under abnormal conditions within a specified time.

[0003] The integral design of traditional switches makes them inflexible in maintenance and replacement. Once a switch fails, it usually needs to be replaced as a whole, rather than being able to replace only the damaged part, which increases the complexity and cost of maintenance. Secondly, the design of traditional switches at the wiring terminals often lacks stability and reliability. The connection between the cable and the switch is prone to loosening or displacement, resulting in poor contact or open - circuit problems, seriously affecting the stability and safety of the circuit system. In view of the above situation, we have introduced a miniaturized modular single - pole single - throw switch. Content of the Utility Model

[0004] The purpose of the utility model is to provide a miniaturized modular single - pole single - throw switch to solve the problems of inconvenient modular design of equipment and poor wiring stability mentioned in the above background technique.

[0005] The technical solution of the utility model is as follows:

[0006] A bottom plate, on the upper end surface of which there is a connecting plate. On the left side of the lower end surface of the connecting plate, there is a positioning block fixedly connected. A threaded bolt is connected inside the positioning block and the connecting plate. On the left - hand edge of the upper end surface of the bottom plate, there is a positioning groove, and the positioning block is located inside the positioning groove;

[0007] The lower end of the connecting plate is fixedly connected with a vertical plate. Inside the inner wall of the vertical plate, there is a first fixing plate. A threaded rod is threadedly connected inside the first fixing plate. The lower end of the threaded rod is rotatably connected with a contact piece. The front end of the contact piece is fixedly connected with an insulating rod, and the end of the insulating rod is fixedly connected with a clamping ring, and the connecting plate is rotatably connected with the threaded rod.

[0008] Furthermore, below the contact piece, on the inner wall of the vertical plate, there is a second fixing plate. On the front - end wall of the second fixing plate, there is a support rod fixedly connected. On the upper - end surface of the support rod, there is a support ring fixedly connected.

[0009] When the contact piece fits with the second fixed plate, the connection of the butt joint wire end is realized, and the operation is simple and convenient. At this time, the insulating rod and the clamping ring fixedly connected to the contact piece move downward, approach the support rod and the support ring fixed on the second fixed plate and the clamping ring, and clamp the cable at the butt joint wire end, providing a stable cable clamping force, and can also ensure good contact between the wire end and the contact piece, and can ensure the stability of the cable during the connection process.

[0010] Furthermore, a rubber ring is fixedly connected to the edge of the upper end surface of the clamping ring.

[0011] Due to the soft and elastic rubber material of the rubber ring, it can reduce the damage to the cable surface when clamping the cable.

[0012] The present utility model provides a miniaturized modular single-pole single-throw switch through improvement. Compared with the prior art, it has the following improvements and advantages:

[0013] First: In the present utility model, the connecting plate is positioned and connected with the bottom plate through the snap connection of the positioning block and the positioning groove, reducing the possibility of loosening and poor contact, thereby improving the reliability of the switch. Then, by rotating the threaded bolt, the wiring seat at the upper end of the connecting plate can be detachably operated, making each part of the switch more modular, facilitating production and maintenance. When a certain part has a problem, that part can be replaced separately.

[0014] Second: In the present utility model, the threaded rod rotatably connected inside the first fixed plate enables the contact piece to slide downward along the vertical plate. When the contact piece fits with the second fixed plate, the connection of the butt joint wire end is realized, and the operation is simple and convenient. At this time, the insulating rod and the clamping ring fixedly connected to the contact piece move downward, approach the support rod and the support ring fixed on the second fixed plate and the clamping ring, and clamp the cable at the butt joint wire end, providing a stable cable clamping force, and can also ensure good contact between the wire end and the contact piece, and can ensure the stability of the cable during the connection process, reducing problems of poor contact or open circuit caused by cable loosening or displacement, and the limiting plate installed on the inner wall of the contact seat can limit the moving range of the contact blade, preventing it from moving excessively or being misaligned, thereby improving the stability and reliability of the switch.
