Description

Technical Field

[0001] This utility model belongs to the field of plug technology, and in particular relates to a plug insulator that is easy to plug and unplug. Background Technology

[0002] A plug is a common electrical accessory, typically consisting of an insulated shell, metal contacts, and connecting wires. It connects electrical devices to a power source, enabling the transmission of current. Plugs are designed with safety, ease of use, and durability in mind, and come in different sizes and types to accommodate various electrical devices and power outlets. When using plugs, safety guidelines must be followed to ensure proper connection and insertion / removal.

[0003] In common plug designs, the insulator typically uses a simple cylindrical, square, or spindle-shaped structure. Users often need to apply considerable force when unplugging the plug, which can easily damage the plug and socket. In addition, common insulator designs are prone to slipping during insertion and removal, causing inconvenience and potentially leading to the operator's fingers slipping, causing them to lean backward, or even resulting in a safety accident due to excessive force. Utility Model Content

[0004] The purpose of this invention is to provide a plug insulator that facilitates insertion and removal, in order to solve the common problem of plugs slipping during insertion and removal.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: it includes an insulator, two contacts are provided on the inner side of the insulator, a connecting wire is provided at the other end of the insulator, the connecting wire is electrically connected to the contacts, recessed clamping grooves are provided on both sides of the insulator, a finger-blocking protrusion is provided on one side of the clamping groove, a through groove is provided in the middle of the finger-blocking protrusion, and the contact surface between the finger-blocking protrusion and the clamping groove is an arc-shaped surface.

[0006] Furthermore, the clamping groove is provided with several anti-slip strips, the height of which is not higher than the height of the clamping groove, and the edges and corners of the anti-slip strips are all rounded.

[0007] Furthermore, there is a height difference between the through groove and the clamping groove, the contact surfaces between the two sides of the through groove and the finger-blocking protrusion are all arc-shaped surfaces, and the surface of the through groove is provided with anti-slip stripes.

[0008] Furthermore, the two contacts are covered with mounting bodies, which are fixed to the contacts and then connected to the insulator.

[0009] Furthermore, the insulator is a one-piece design.

[0010] Beneficial effects: This utility model is reasonably designed and has the following beneficial effects:

[0011] In this utility model, the operator's index finger is in the clamping groove below the insulator, and the thumb is in the through groove above the insulator. When the operator pulls the insulator out backward, the finger-blocking protrusion abuts against the inside of the index finger, and the height difference angle between the through groove and the clamping groove abuts against the thumb pad. At the same time, the part of the index finger and thumb that falls into the clamping groove contacts the anti-slip strip. There are also anti-slip stripes between the thumb pad and the through groove to increase friction. With the cooperation of these elements, more force points and greater friction are provided to facilitate the removal of the plug. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Combination Figures 1 to 2 The plug insulator shown includes an insulator 1, with two contacts 2 on the inner side of the insulator 1 and a connecting wire 3 at the other end of the insulator 1. The connecting wire 3 is electrically connected to the contacts 2. Both sides of the insulator 1 are provided with recessed clamping grooves 4. One side of the clamping groove 4 is provided with a finger-blocking protrusion 5. The middle of the finger-blocking protrusion 5 is provided with a through groove 6. The contact surface between the finger-blocking protrusion 5 and the clamping groove 4 is an arc-shaped surface.

[0017] The clamping groove 4 is provided with several anti-slip strips 7. The height of the anti-slip strips 7 is not higher than the height of the clamping groove 4, and the corners of the anti-slip strips 7 are all rounded.

[0018] There is a height difference between the through groove 6 and the clamping groove 4. The contact surfaces between the two sides of the through groove 6 and the finger-blocking protrusion 5 are all arc-shaped surfaces. The surface of the through groove 6 is provided with anti-slip stripes.

[0019] The two contacts 2 are wrapped with mounting bodies 8. The mounting bodies 8 are fixed to the contacts 2 and then connected to the insulator 1.

[0020] Insulator 1 is a one-piece design.

[0021] Working principle: During use, the recessed clamping grooves 4 on both sides of the insulator 1 provide a convenient gripping point for the operator's fingers (especially the index finger). When the operator grips the recessed clamping groove 4 with the index finger, the finger-blocking protrusion 5 can abut against the inside of the index finger, thereby increasing the stability and force transmission efficiency during insertion and removal.

[0022] The through groove 6 prevents the thumb from being blocked by the finger-blocking protrusion 5, making it difficult to apply force. The height difference design between the through groove 6 and the clamping groove 4 allows the thumb pad to naturally fall on the corner formed by the height difference when the operator grips it with their thumb. This corner provides an additional support point and increases the force when inserting or removing the thumb.

[0023] The anti-slip strip 7 on the clamping groove 4 increases the friction between the fingers and the insulator 1, preventing the fingers from slipping during insertion and removal. The anti-slip strip 7 texture on the surface of the through groove 6 also increases the friction between the thumb and the through groove 6, further improving the stability and efficiency of insertion and removal.

[0024] When the operator holds the clamping groove 4 with their index finger and the through groove 6 with their thumb, the index finger and thumb can form a stable grip posture due to the design of the finger-blocking protrusion 5 and the height difference. When pulling the insulator 1 out backward, the index finger and thumb act together on the insulator 1 through the friction provided by the anti-slip strip 7 and the anti-slip strip 7 texture, as well as the support points provided by the clamping groove 4 and the through groove 6, thereby generating sufficient pulling force.

[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
