Specific embodiments

[0025] The following further Figures 1-6 describes the present application in detail with reference to the attached

[0026] The embodiments of the present application disclose an insulating protection switch terminal.

[0027] Referring to Figures 1-6 , an insulating protection switch terminal includes an insulating housing 101, an insulating cover plate 102 is installed on the top of the insulating housing 101 through a detachable structure, a wiring port 103 is arranged on the front side of the insulating housing 101, a U-shaped insulating side plate 202 is slidably installed on the front side of the insulating housing 101, and the U-shaped insulating side plate 202 is adapted to the wiring port 103. T-shaped guide seats 201 are fixedly installed on both sides of the insulating housing 101. Two T-shaped guide holes 204 are opened at the top of the U-shaped insulating side plate 202, and one side where the two T-shaped guide holes 204 are close to each other is an opening. The T-shaped guide seat 201 is slidably connected to the T-shaped guide hole 204. Limit seats 203 are fixedly installed on both sides of the insulating housing 101, and the U-shaped insulating side plate 202 is adapted to the limit seats 203.

[0028] In this embodiment, a threaded hole 401 is formed in the inner wall of the T-shaped guide hole 204 on the side far from its opening. A locking mechanism for fixing the U-shaped insulating side plate 202 is provided in the threaded hole 401. The locking mechanism includes a locking screw 402 and a knob 403. The locking screw 402 is threadedly installed in the threaded hole 401. The locking screw 402 is adapted to the T-shaped guide seat 201. A knob 403 is fixedly installed at one end of the locking screw 402. With this design based on the simple principle of threaded connection, the user only needs to rotate the knob 403 to easily achieve the close contact or separation between the locking screw 402 and the T-shaped guide seat 201. When it is necessary to adjust the shielding of the U-shaped insulating side plate 202 for wiring ports 103 at different positions, the operator can quickly complete the operation, improving the work efficiency. Moreover, the stable fixing method ensures that the U-shaped insulating side plate 202 will not slide randomly due to external force collision or other factors during use, enhancing the stability of the entire insulation protection structure.

[0029] In this embodiment, two adjusting plates 301 are slidably installed on the top of the U-shaped insulating side plate 202. The adjusting plates 301 are adapted to the corresponding wiring ports 103. A guiding mechanism is provided between the adjusting plates 301 and the U-shaped insulating side plate 202. The guiding mechanism includes a connecting seat 501, a connecting rod 502 and a sliding hole 503. Two connecting seats 501 are fixedly installed on the top of the U-shaped insulating side plate 202. The same connecting rod 502 is fixedly installed between the two connecting seats 501. A sliding hole 503 is formed in the adjusting plate 301, and the connecting rod 502 is slidably connected to the sliding hole 503. The setting of this guiding mechanism enables the adjusting plates 301 to slide smoothly and precisely on the U-shaped insulating side plate 202. When facing multiple wiring ports 103 and it is necessary to provide targeted protection for a single or some of the ports, the operator can conveniently move the adjusting plates 301 in front of the specified wiring ports 103. The design that the adjusting plates 301 are adapted to the wiring ports 103 can precisely shield the unused wiring ports 103 individually, effectively preventing impurities such as dust and water vapor from entering through a single unused port, further improving the insulation protection performance of the switch terminals. Moreover, this structure is simple and reliable, reducing the risk of equipment failure.

[0030] In this embodiment, a plurality of hemispherical grooves 601 are formed at the top of the connection base 501, and a moving groove 602 is formed at the top of the sliding hole 503. A latching mechanism adapted to the hemispherical groove 601 is provided in the moving groove 602. The latching mechanism includes a convex block 603 and a fixing spring 604. The convex block 603 is slidably installed in the moving groove 602. The convex block 603 is adapted to the corresponding hemispherical groove 601. A fixing spring 604 is fixedly installed at the top of the convex block 603, and the top end of the fixing spring 604 is fixedly installed on the inner wall of the top of the moving groove 602. This latching mechanism provides a clever and reliable way for fixing the adjusting plate 301. When the adjusting plate 301 moves to a suitable position, the convex block 603 automatically falls into the hemispherical groove 601 under the elastic force of the fixing spring 604, realizing the locking of the adjusting plate 301. The operator can complete the fixing operation only by pushing the adjusting plate 301 without the aid of additional tools, and the operation process is simple and easy to understand. Moreover, the arrangement of a plurality of hemispherical grooves 601 enables the adjusting plate 301 to be fixed at different positions, increasing the flexibility of adjustment. According to the actual use situation of the wiring port 103, the position of the adjusting plate 301 can be flexibly adjusted, so as to better meet the diverse insulation protection requirements.

[0031] In this embodiment, a first rubber strip 205 in contact with the insulating housing 101 is installed on the front inner wall of the U-shaped insulating side plate 202, and a second rubber strip 302 in contact with the insulating housing 101 is fixedly installed on the rear side of the adjusting plate 301. The first rubber strip 205 and the second rubber strip 302 play a role of double-sealing insulation. The first rubber strip 205 closely adheres to the insulating housing 101, effectively blocking impurities such as dust and water vapor that may enter from the connection between the U-shaped insulating side plate 202 and the insulating housing 101, and further improving the protection effect on the lower wiring port 103. The second rubber strip 302 seals the contact part between the adjusting plate 301 and the insulating housing 101 to prevent impurities from entering through the gap between the adjusting plate 301 and the insulating housing 101. At the same time, the rubber strip has a certain elasticity, which can buffer the impact force generated by the adjusting plate 301 and the U-shaped insulating side plate 202 on the insulating housing 101 during the moving process while ensuring the sealing effect, protecting the insulating housing 101 from damage, prolonging the service life of the entire switch terminal, and greatly enhancing the safety and reliability of the switch terminal.

[0032] In the present utility model, when covering the unconnected wiring port 103, by sliding the U-shaped insulating side plate 202 upward, the U-shaped insulating side plate 202 can cover a plurality of wiring ports 103 located below. By rotating the knob 403 and the locking screw 402, under the action of the threaded hole 401, the locking screw 402 can rotate and move at the same time. The locking screw 402 can be in close contact with the T-shaped guide seat 201, and the purpose of fixing the U-shaped insulating side can be achieved. By moving the adjusting plate 301, the convex block 603 can be extruded and move upward. The convex block 603 can be received in the moving groove 602 and compress the fixing spring 604. When the adjusting plate 301 moves to the front side of the corresponding wiring port 103, at this time, the fixing spring 604 can push the convex block 603 into the hemispherical groove 601, and the purpose of fixing the adjusting plate 301 can be achieved. By the adjusting plate 301, the unconnected wiring port 103 located above can be covered.

[0033] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
