[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.
[0024] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0025] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.
[0026] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.
[0027] Example 1, reference Figure 1 to Figure 2 , which is the first embodiment of the present invention, provides a low-voltage wire end insulation device, including a connecting mechanism 100, including a support block 101 and a clamping member 102 arranged on the support block 101; a wire end 200, which is plugged into the connecting mechanism 100; and the connecting mechanism 100 is made of insulating material.
[0028] Specifically, the support block 101 includes an end surface and a first side surface, and the end surface and the first side surface are both provided with a first groove.
[0029] Furthermore, the end surface of the support block 101 is connected to the upper cover 103 , and a through hole is opened at the center of the upper cover 103 .
[0030] It should be noted that the entire connection mechanism 100 is made of insulating material to ensure electrical safety and prevent electric shock accidents. The support block 101 is designed with an end face and a first side face, both of which are provided with a first groove. This arrangement not only enhances the stability of the structure, but also provides installation space for internal components such as springs 102c. The end face of the support block 101 is connected to an upper cover 103. The through hole in the center of the upper cover 103 allows the wire head 200 to pass through and be inserted into the first space 102d inside the device. This space is composed of a pressing block 102a and a wire pressing plate 102b, which work together to clamp the wire head 200. The upper cover 103 is provided with a through hole so that the wire head 200 can be easily inserted and fixed in place, while maintaining the sealing and integrity of the insulating device, ensuring the insulation effect and ease of operation.
[0031] Example 2, reference Figures 1 to 3 This embodiment is different from the first embodiment in that the clamping member 102 includes a pressing block 102a and a wire pressing plate 102b disposed on the pressing block 102a, and the pressing block 102a and the wire pressing plate 102b cooperate to clamp the wire head 200.
[0032] Specifically, the side wall of the pressing block 102a is in contact with the inner wall of the supporting block 101, and through grooves are formed on both sides of the pressing block 102a.
[0033] Furthermore, the through grooves on both sides of the wire pressing plate 102b penetrate through both sides of the pressing block 102a and are connected to the inner wall of the supporting block 101, and the cross section of the wire pressing plate 102b is arc-shaped.
[0034] It should be noted that the pressing block 102a and the wire pressing plate 102b are used together to clamp and fix the wire head 200, ensuring that the wire head 200 is firmly fixed inside the insulating device to achieve effective insulation protection. The collaborative work of the pressing block 102a and the wire pressing plate 102b provides a mechanical clamping mechanism, so that the wire head 200 can be tightly clamped after insertion to prevent loosening due to external force or vibration, thereby ensuring the stability and safety of the electrical connection.
[0035] The side wall of the pressing block 102a fits with the inner wall of the supporting block 101, so that the pressing block 102a can move stably in the supporting block 101, while providing sufficient supporting force to clamp the wire head 200. The through grooves on both sides of the pressing block 102a allow the wire pressing plate 102b to pass through and connect with the inner wall of the supporting block 101. Such a structural design not only enhances the mechanical strength of the clamping member 102, but also enables the wire pressing plate 102b to effectively apply pressure to the wire head 200 under the guidance of the pressing block 102a.
[0036] The cross section of the wire pressing plate 102b is designed to be arc-shaped, which is conducive to evenly distributing the pressure on the wire head 200. No matter how the cross section of the wire head 200 changes, the arc-shaped wire pressing plate 102b can fit it tightly, ensuring that the wire head 200 will not be damaged during the insertion and clamping process, while also improving the insulation effect. The arc design also makes the wire head 200 smoother when inserted and removed, reducing friction and damage risks during operation.
[0037] The rest of the structure is the same as that of Example 1.
[0038] Example 3, reference Figures 1 to 3 This embodiment is different from the above embodiments in that: the pressing block 102a is provided with an inserting slot from the top to the bottom, and the inserting slot is used to insert the wire head 200.
[0039] Specifically, the surface of the pressing block 102a located in the first groove of the supporting block 101 is the first side surface, and the surface of the pressing block 102a away from the first groove is the second side surface.
[0040] Furthermore, a spring 102c is provided between the first side surface and the first groove, and a phase sequence mark is provided on the second side surface.
[0041] Furthermore, a first space 102d is formed between the pressing block 102a and the wire pressing plate 102b, and the wire head 200 enters the first space 102d through the through groove of the upper cover 103; after the wire head 200 enters the first space 102d, its outer wall simultaneously conflicts with the pressing block 102a and the wire pressing plate 102b; the cross-section of the first space 102d changes following the cross-section of the wire head 200.
[0042] It should be noted that the pressing block 102a is provided with a plug-in groove from the top to the bottom. This groove is specially designed for the wire head 200, allowing the wire head 200 to be smoothly inserted and fixed in place. The pressing block 102a enables the wire head 200 to be directly inserted and clamped, providing a quick and reliable connection method.
[0043] One side (first side) of the pressing block 102a is located in the first groove of the supporting block 101, while the other side (second side) is away from the groove, so that the pressing block 102a can move stably in the supporting block 101. At the same time, the spring 102c arranged between the first side and the first groove provides the necessary elastic force for the pressing block 102a, so that the pressing block 102a can automatically return to its original position after being released, thereby achieving the tightening of the wire head 200.
[0044] A phase sequence mark is provided on the second side of the pressing block 102a, which helps the staff to quickly identify and distinguish wires of different phase sequences, avoid errors during connection, and improve the accuracy and safety of construction.
[0045] The first space 102d formed between the pressing block 102a and the wire pressing plate 102b is the key area for the wire head 200 to be inserted and clamped. The wire head 200 enters this space through the through slot of the upper cover 103, and when the wire head 200 is fully inserted, its outer wall will collide with the pressing block 102a and the wire pressing plate 102b to achieve clamping. The cross-section of this space is designed to change with the cross-section of the wire head 200, which means that the first space 102d of most wire heads 200 can adapt and ensure that the wire head 200 is evenly and firmly clamped, thereby providing a good insulation effect.
[0046] The rest of the structure is the same as that of Example 2.
[0047] Operation process: During power construction, when it is necessary to insulate the exposed conductor part of the wire head 200, first press the pressing block 102a on the support block 101 in the direction of the first groove. At this time, the cross-section of the first space 102d becomes larger, and then insert the wire head 200 into the first space 102d through the through hole of the upper cover 103 until the wire head 200 is inserted into the bottom end of the first space 102d. At this time, release the pressing block 102a. The pressing block 102a will move away from the first groove under the elastic force of the spring 102c until the wire head 200 simultaneously conflicts with the pressing block 102a and the wire pressing plate 102b. At this time, the insulation work of the wire head 200 is completed.
[0048] Compared with the existing method of wrapping the wire head 200 with insulating tape, the present invention is simple to operate and easy to implement.
