Description

Technical Field

[0001] This utility model belongs to the field of plug and socket technology, and more specifically, it relates to a mating structure for an anti-dislodgement plug and socket. Background Technology

[0002] Currently, the plug-socket mating structure widely used in the market relies primarily on the static friction generated between the outer wall of the plug and the inner wall of the socket after the plug is inserted. This friction-based fastening method has the advantages of simple structure and low manufacturing cost, and is the basic solution for power connections in the vast majority of household appliances, office equipment, and industrial equipment.

[0003] However, the aforementioned fastening method relying on the friction of the contact surface has significant drawbacks: its anti-detachment effect is very limited and unreliable. First, the magnitude of friction is limited by the material, smoothness, wear level, and fit tolerances of the contact surfaces, and is easily reduced due to wear, aging, or contamination with oil and dust from repeated plugging and unplugging. Second, this friction can only effectively resist slight pulling forces along the plug's axis (in the pulling direction). It is insufficient to provide enough holding force against vibrations from the appliance itself or accidental pulling of the power cord, resulting in a high risk of accidental plug detachment during use. Once the plug loosens or detaches, it not only interrupts the power supply to the device and affects normal use, but more seriously, it may cause arcing, overheating due to poor contact, and even lead to electric shock or fire, posing a significant safety hazard. Therefore, there is an urgent need for a plug-socket mating structure that is simple in structure, reliable, and can effectively prevent accidental loosening. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a mating structure for an anti-dislodgement plug and socket, which is achieved by the following specific technical means:

[0005] A mating structure for an anti-disengagement plug and socket includes a matching plug assembly and a socket. The plug assembly includes a plug and an anti-disengagement ring, which is rotatably mounted on the outside of the plug. A sliding groove is provided on the outside of the plug, and a slider is provided on the inner rear end of the anti-disengagement ring, which is slidably connected to the sliding groove. An elastic element is installed inside the sliding groove, and one end of the elastic element abuts against the slider to reset the anti-disengagement ring. A locking block is provided on the inner front end of the anti-disengagement ring, and a connecting ring is provided at the end of the socket, with a locking groove on the outside of the connecting ring for connecting with the locking block.

[0006] Furthermore, two sets of positioning strips are symmetrically arranged on the outer wall of the plug, and two sets of positioning grooves are arranged on the inner wall of the connecting ring that can slide and connect with the positioning strips.

[0007] Furthermore, two sets of slides are provided and are located on the outer side of the root of the plug; the root of the plug is provided with two sets of inlet slots that communicate with one end of the respective slides, and the inlet slots are provided with anti-reverse slopes near the point of communication with the slides.

[0008] Furthermore, there are two sets of sliders, which can slide into the groove through the corresponding inlet.

[0009] Furthermore, the locking blocks are configured in two sets and symmetrically arranged on the inner front end of the anti-detachment rotating ring; the front end of the locking block is provided with a driving slope, and the rear end is a locking plane.

[0010] Furthermore, two sets of slots are provided and symmetrically arranged on the outside of the connecting ring; a protrusion is provided at the opening of the slot, and one end of the protrusion is provided with a pressing slope parallel to the driving slope, and the inner end of the protrusion is a flat surface for engaging with the locking surface.

[0011] Furthermore, the elastic element is a spring, and two sets of protrusions for clamping the spring are symmetrically arranged at one end of the slide groove.

[0012] Furthermore, the outer side of the anti-slip ring is equipped with an unlocking indicator arrow and anti-slip texture.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This utility model employs a mechanical interlocking structure. When the plug is inserted into the socket and the anti-dislodgement ring is rotated, the locking block automatically embeds into the locking plane of the slot under the action of the elastic element, forming a firm locking state. This rigid connection method can provide a holding force far greater than friction, effectively resisting the axial tension generated by equipment operation vibration and accidental pulling of the power cord. It fundamentally solves the problem of traditional plugs being easy to loosen and accidentally fall off, ensuring the continuous and stable power supply connection. Attached Figure Description

[0027] Example:

[0028] As attached Figure 1 To be continued Figure 6 As shown:

[0029] This utility model provides a mating structure for an anti-disengagement plug and socket, including a matching plug assembly 1 and a socket 2. The plug assembly 1 includes a plug 11 and an anti-disengagement rotating ring 12, which is rotatably mounted on the outside of the plug 11. A sliding groove 112 is provided on the outside of the plug 11. A slider 121 is provided on the inner rear end of the anti-disengagement rotating ring 12, which is slidably connected to the sliding groove 112. An elastic element is installed inside the sliding groove 112, and one end of the elastic element abuts against the slider 121 to reset the anti-disengagement rotating ring 12. A locking block 122 is provided on the inner front end of the anti-disengagement rotating ring 12. A connecting ring 21 is provided at the end of the socket 2, and a locking groove 212 for connecting with the locking block 122 is provided on the outside of the connecting ring 21.

[0030] The plug 11 has two sets of positioning strips 111 symmetrically arranged on its outer side wall, and the connecting ring 21 has two sets of positioning grooves 211 that can slide and connect with the positioning strips 111. The symmetrical positioning strips 111 and positioning grooves 211 cooperate to ensure that the plug 11 has the correct angle and direction when it is inserted into the socket 2, guide the plug 11 to be inserted accurately, and avoid damage to the components caused by blind insertion.

[0031] The slide groove 112 is provided in two sets and is located on the outer side of the root of the plug 11; the root of the plug 11 is provided with two sets of inlet slots 114 that communicate with one end of the slide groove 112 respectively, and the inlet slot 114 is provided with a backstop slope near the point where it communicates with the slide groove 112. The slider 121 is provided in two sets and can slide into the slide groove 112 through the inlet slot 114 respectively. The groove 114 facilitates the quick installation of the anti-detachment rotating ring 12 during production assembly. When the slider 121 of the anti-detachment rotating ring 12 is inserted into the groove 114, it drives the anti-detachment rotating ring 12 to rotate towards the position of the slide groove 112. At this time, the slider 121 moves along the anti-reverse slope. When a "click" is heard or a vibration is felt, the slider 121 passes over the anti-reverse slope and enters the slide groove 112, thus completing the installation of the anti-detachment rotating ring 12. Due to the anti-reverse slope, the slider 121 will not easily detach after entering the slide groove 112, thus ensuring the stability of the anti-detachment rotating ring 12. The anti-detachment rotating ring 12, slider 121, and locking block 122 are an integral injection-molded structure.

[0032] The locking blocks 122 are configured in two sets and symmetrically arranged on the inner front end of the anti-detachment rotating ring 12. The front end of the locking block 122 is provided with a driving slope and the rear end is a locking plane. The slots 212 are configured in two sets and symmetrically arranged on the outer side of the connecting ring 21. The opening of the slot 212 is provided with a protrusion, and one end of the protrusion is provided with a pressing slope parallel to the driving slope. The inner end of the protrusion is a plane for engaging with the locking plane. The functions of the driving ramp and the pressing ramp are as follows: When the plug 11 is inserted into the socket 2, the driving ramp of the locking block 122 and the pressing ramp of the protrusion of the slot 212 come into contact and press against each other. As the plug 11 continues to advance, the interaction force between the ramps generates a tangential component force, forcing the anti-disengagement ring 12 to overcome the force of the spring 113 and rotate circumferentially. When the plug 11 is fully inserted into the socket 2, the driving ramp just passes the top of the pressing ramp and disengages. At this time, the pre-compressed spring 113 releases its elastic potential energy, drives the anti-disengagement ring 12 to rotate in the opposite direction and reset, thereby driving the locking plane to accurately embed into the inner end plane of the protrusion of the slot 212, forming a firm limiting engagement state. Conversely, when unlocking, it is only necessary to rotate the anti-disengagement ring 12 in the opposite direction to make the locking block 122 disengage from the slot 212 and pull it out.

[0033] Among them, the elastic element is a spring 113. Two sets of protrusions for clamping the spring 113 are symmetrically arranged at one end of the slide groove 112 to ensure that the spring 113 is stable in position during compression and reset, without tilting or falling out, thus ensuring the reliability and durability of the reset function.

[0034] The anti-slip ring 12 features an unlocking indicator arrow and anti-slip texture on its outer side. The unlocking indicator arrow provides clear and intuitive operation guidance, significantly improving the product's ease of use and preventing damage or unlocking failure due to incorrect operation direction. The anti-slip texture increases the friction between the finger and the surface of the anti-slip ring 12, making rotation operation easier and more reliable, especially in wet or slippery conditions, enhancing user experience and operational safety.

[0035] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
