DETAILED DESCRIPTION

[0026] The following is a clear and complete description of the technical solutions of the present invention in conjunction with the embodiments. Obviously, the embodiments described are only a part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0027] See Figure 2-Figure 6 , the utility model provides a technical solution:

[0028] A stable insulating gland structure for components, comprising an insulating upper cover 1, an insulating lower cover 2, an intermediate spring piece 3, a spring piece limiting frame 4, an upper anti-slip protrusion 5, a lower anti-slip protrusion 6 and a quick-connect assembly. The insulating upper cover 1 is arranged on the insulating lower cover 2 and cooperates with the insulating lower cover 2. Both ends of the insulating upper cover 1 and the two ends of the insulating lower cover 2 are connected by a quick-connect assembly. A spring piece limiting frame 4 is fixedly arranged on the middle part of the insulating lower cover 2. The spring piece limiting frame 4 is provided with an intermediate spring piece 3 with the middle part bent toward the side of the insulating lower cover 2. The lower anti-slip protrusion 6 is fixedly arranged on the insulating lower cover 2. The upper anti-slip protrusion 5 is fixedly arranged on the insulating upper cover 1, and the lower anti-slip protrusion 6 is arranged between the quick-connect assembly and the end of the spring piece limiting frame 4. The upper anti-slip protrusion 5 is arranged between the end of the spring piece limiting frame 4 and the lower anti-slip protrusion 6. Among them, the insulating upper cover 1, the insulating lower cover 2, the spring clip limit frame 4, the upper anti-slip protrusion 5, the lower anti-slip protrusion 6 and the quick-connect assembly are all made of insulating materials, generally made of plastic. The middle spring clip 3 is made of metal material. Under the action of the middle spring clip 3, the degree of deformation of the insulating upper cover 1 and the insulating lower cover 2 during operation is reduced. The spring clip limit frame 4 is a square frame, and the projection of the middle spring clip 3 on the insulating lower cover 2 is also square. The function of the spring clip limit frame 4 is to prevent the middle spring clip 3 from being fixed in position between the insulating upper cover 1 and the insulating lower cover 2, resulting in the inability to fix the electronic components. The function of the quick-connect assembly is to fix the insulating upper cover 1 and the insulating lower cover 2 together, and also to facilitate the disassembly of the insulating upper cover 1 and the insulating lower cover 2. The spring clip limit frame 4, the upper anti-slip protrusion 5 and the lower anti-slip protrusion 6 are used in combination to prevent the insulating upper cover 1 and the insulating lower cover 2 from being misaligned during operation.

[0029] In some embodiments, upper anti-slip protrusions 5 are symmetrically provided on both ends of the insulating upper cover 1, and lower anti-slip protrusions 6 are symmetrically provided on both ends of the insulating lower cover 2. Providing two sets of upper anti-slip protrusions 5 and two sets of lower anti-slip protrusions 6 can further limit relative sliding between the insulating upper cover 1 and the insulating lower cover 2, preventing the quick-connect components connecting the two ends from breaking.

[0030] In some embodiments, a limiting lower step 7 is provided on one side of the insulating lower cover 2, and a limiting upper step 8 is provided on one side of the insulating upper cover 1 to cooperate with the limiting lower step 7. A limiting outer boss 9 and a limiting inner boss 10 are provided on the other side of the insulating lower cover 2, and both ends of the limiting inner boss 10 are fixedly connected to the lower anti-slip protrusion 6. A limiting platform 11 is provided on the other side of the insulating upper cover 1, and the limiting platform 11 is provided between the limiting outer boss 9 and the limiting inner boss 10. Among them, the limiting lower step 7 cooperates with the limiting upper step 8, and the limiting outer boss 9 and the limiting inner boss 10 cooperate with the limiting platform 11, jointly limiting the sliding between the insulating upper cover 1 and the insulating lower cover 2 to the sides, making the cooperation between the insulating upper cover 1 and the insulating lower cover 2 more stable, and ensuring the stability of the electronic components when fixed. In order to prevent the upper anti-slip protrusion 5 and the lower anti-slip protrusion 6 from being broken, the two ends of the limiting inner boss 10 are fixedly connected to the two lower anti-slip protrusions 6 respectively, one end of the upper anti-slip protrusion 5 is fixedly connected to the limiting platform 11, and the other end of the upper anti-slip protrusion 5 is fixedly connected to the limiting upper step 8.

[0031] In some embodiments, the middle spring piece 3 is provided with an anti-slip hole 12, in which an anti-slip rod 13 is provided. The anti-slip rod 13 is fixedly mounted on the insulating upper cover 1 or the insulating lower cover 2. The anti-slip rod 13 is fixed to the insulating lower cover 2 and engages with the anti-slip hole 12 on the middle spring piece 3. This effectively prevents the middle spring piece 3 from rotating within the spring piece limiting frame 4 and also prevents the middle spring piece 3 from sliding a large distance within the spring piece limiting frame 4.

[0032] In some embodiments, both ends of the intermediate spring piece 3 are provided with arc-shaped end pieces 14, which are bent toward the insulating upper cover 1. Since the intermediate spring piece 3 is made of metal and the insulating lower cover 2 is made of plastic, the provision of the arc-shaped end pieces 14 prevents the ends of the intermediate spring piece 3 from being inserted into the insulating lower cover 2 during operation, thereby preventing the insulating lower cover 2 from being damaged.

[0033] In some embodiments, the quick-connect assembly includes an upper connecting buckle 15 and a lower connecting buckle 16. The upper connecting buckle 15 is fixedly mounted on the end of the insulating upper cover 1, and the lower connecting buckle 16 is fixedly mounted on the end of the insulating lower cover 2 to cooperate with the upper connecting buckle 15. Both the upper connecting buckle 15 and the lower connecting buckle 16 are made of insulating plastic. When the upper connecting buckle 15 and the lower connecting buckle 16 are fastened together, they function as a connection. When the upper connecting buckle 15 and the lower connecting buckle 16 are separated, the insulating upper cover 1 and the insulating lower cover 2 can be separated.

[0034] In some embodiments, an upper mounting hole 17 is provided in the middle of the insulating upper cover 1, a lower mounting hole 18 is provided on the insulating lower cover 2 to mate with the upper mounting hole 17, a middle mounting hole 19 is provided in the middle of the intermediate spring piece 3 to mate with the lower mounting hole 18, and a lifting ring 20 is fixedly mounted on the lower mounting hole 18 to mate with the intermediate spring piece 3. The upper mounting hole 17, the middle mounting hole 19, and the lower mounting hole 18 are used in conjunction with screws to secure the device to the desired device. The provision of the lifting ring 20 can prevent the intermediate spring piece 3 from being severely deformed and unable to return to its original state.

[0035] In some embodiments, the insulating upper cover 1 is fixedly provided with a mounting ring 21 that mates with the upper mounting hole 17. An anti-rotation protrusion 22 is fixedly provided on the outer wall of the mounting ring 21, and an anti-slip protrusion 23 is fixedly provided on the upper end of the anti-rotation protrusion 22, which does not contact the outer wall of the mounting ring 21. The side of the anti-rotation protrusion 22 is fixedly connected to the outer wall of the mounting ring 21. One end of the anti-rotation protrusion 22 is fixed to the insulating upper cover 1, and the anti-slip protrusion 23 is fixed to the other end of the anti-rotation protrusion 22. The combination of the mounting ring 21, the anti-rotation protrusion 22, and the anti-slip protrusion 23 allows other components to be installed on the insulating upper cover 1.

[0036] In some embodiments, the insulating lower cover 2 is provided with a mounting groove 25 for fixing the component 24, and the mounting groove 25 is provided with a locking buckle 26 for fixing the component 24. The mounting groove 25 is used to position the component 24, and the locking buckle 26 is used to fix the component 24 in the mounting groove 25.
