Description

Technical Field

[0001] The utility model relates to the technical field of terminal insulation, in particular to a terminal block anti-miscontact insulation cover capable of being inflated. Background Art

[0002] A terminal block anti-miscontact insulation cover is an insulation cover used to protect the terminal block from being miscontacted and touched. It is usually made of insulating material and can cover the terminal block to prevent external objects or fingers from contacting the conductive parts on the terminal block, thereby reducing the risk of electric shock. The terminal block anti-miscontact insulation cover is widely used in industrial and household electrical equipment;

[0003] However, the existing terminal block anti-miscontact insulation covers either adopt soft materials or hard materials. The soft-material terminal block anti-miscontact insulation cover lacks the collision buffering function, while the hard-material terminal block anti-miscontact insulation cover is prone to damage its own structure when being collided, resulting in the loss of the insulation protection function. For this reason, a soft-material terminal block anti-miscontact insulation cover with an inflation function is proposed, which not only maintains the characteristic that the structure of the soft material is not damaged during expansion, but also has an effective protection function for the terminal.

[0022] To make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will provide a detailed description of the specific implementation modes of the present utility model in conjunction with the accompanying drawings of the specification.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0024] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation mode of the present utility model. The "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an embodiment that is separate from or mutually exclusive of other embodiments selectively.

[0025] Embodiment

[0026] Referring to Figures 1 to 4 , which is an embodiment of the present utility model. This embodiment provides an anti-misoperation insulation cover for a terminal block, including a main cover 100 and a lining cover 200 connected to the main cover 100. It is characterized in that: the main cover 100 is divided into an outer surface layer 100a and an inner surface layer 100b, and there is a cavity between the two. When a medium is injected into the cavity, the outer surface layer 100a expands outward and separates from the inner surface layer 100b;

[0027] The main cover 100 is used to cover the terminal block, playing functions such as insulation protection, anti-collision, dust prevention, and waterproofing. The lining cover 200 is used to provide insulation protection for the wiring part of the terminal and the part extending to the wire, and is an integrally formed structure with the main cover 100. Among them, the main cover 100 has a structure with an outer surface layer 100a, an inner surface layer 100b, and a hollow in the middle. Therefore, the main cover 100 has triple insulation functions. When the terminal is collided, the main cover 100 with a hollow structure has a good effect of absorbing the collision, and at the same time, the main cover 100 is not easily damaged in structure;

[0028] Specifically, an air nozzle 101 is communicated and provided on the outer surface layer 100a. The thickness of the outer surface layer 100a is less than the thickness of the inner surface layer 100b. The air nozzle 101 has the function of inflating / deflating the hollow structure between the outer surface layer 100a and the inner surface layer 100b to adjust the buffering performance of the main cover 100. The thickness of the outer surface layer 100a is less than the thickness of the inner surface layer 100b, mainly to make the outer surface layer 100a bulge outward and the inner surface layer 100b bulge slightly, so as not to occupy the space for protecting the terminal block. Sufficient space is beneficial to the heat dissipation of the terminal block and has more space for collision defense;

[0029] In order to make the protrusion of the main cover 100 more uniform, and when the main cover 100 is collided, the energy absorption is more uniform and it is not easy to be damaged. Specifically, a mesh structure 100c is provided between the outer surface layer 100a and the inner surface layer 100b. Through holes 100c-1 are opened through the mesh structure 100c. By setting the perforated mesh structure 100c between the outer surface layer 100a and the inner surface layer 100b, the hollow of the main cover 100 is divided into uniform blocks, making the originally soft main cover 100 stronger after inflation, and its structure more like a rigid structure and having the flexible energy absorption characteristics of anti-collision. Therefore, the above setting has a better effect on insulating and protecting the terminal block and anti-collision;

[0030] Specifically, a first adhesive 102 is provided at the bottom of the main cover 100 where the outer surface layer 100a is located, and a second adhesive 201 is provided at the opening of the lining cover 200. The main cover 100 and the lining cover 200 are mainly installed on the terminal block. The number of lining covers 200 provided on the main cover 100 is one or several, and the number of insulating cover lining covers 200 is determined according to the wiring direction and quantity;

[0031] It should be noted importantly that the structures and arrangements of the present application shown in multiple different exemplary embodiments are only illustrative. Although only several embodiments are described in detail in this disclosure, those who refer to this disclosure should easily understand that many modifications are possible on the premise of substantially not deviating from the novel teachings and advantages of the subject matter described in this application (for example, the sizes, scales, structures, shapes and proportions of various components, and parameter values (such as temperature, pressure, etc.), installation arrangements, use of materials, changes in color, orientation, etc.). For example, an element shown as integrally formed can be composed of multiple parts or elements, the position of the element can be inverted or changed in other ways, and the nature, number or position of discrete elements can be changed or altered. Therefore, all such modifications are intended to be included within the scope of the present utility model.
