Abstract
Description
Technical Field
[0001] This application relates to the field of electrical connector technology, specifically to an electrical connector with an anti-slip structure. Background Technology
[0002] In the field of power transmission and signal connection, pluggable electrical connectors are widely used as core components in industrial equipment, communication facilities and consumer electronics. Vibration or frequent plugging and unplugging can easily cause traditional snap-fit structures to loosen, and the direct plug-in design relies only on friction, which can easily slip out under dynamic loads.
[0003] Traditional pluggable connectors typically employ a straight-in or threaded tightening structure. Their anti-slip design mainly relies on the frictional damping force of the contact surface or a simple snap-fit structure. However, under complex operating environments such as vibration, frequent plugging and unplugging, or external pulling forces, conventional snap-fit structures are prone to loosening due to fatigue or deformation. Straight-in designs rely solely on the frictional force of the interference fit, which is prone to slippage under dynamic loads, causing signal interruption or safety hazards. Environmental factors such as humidity and corrosive gases can easily penetrate the contact interface through the connection gap, leading to decreased insulation performance or short-circuit risks. Traditional sealing rings achieve sealing only through radial compression, with limited axial tensile strength. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an electrical connector with an anti-slip structure, which has advantages such as anti-slip properties and easy adjustment of connection tightness, thus solving the problems mentioned in the background art.
[0005] To achieve the above objectives, this application provides the following technical solution: an electrical connector with an anti-slip structure, comprising a male end and an insertion end at one end, and a female end and a mating end at the other end. A threaded post is fixedly connected to the outer surface of the male end, the threaded post and the male end are on the same axis, a threaded sleeve is threadedly connected to the outer surface of the threaded post, a connecting plate is rotatably connected to the end of the threaded sleeve near the insertion end, an insertion plate is fixedly connected to the side of the connecting plate near the insertion end, the edges of the two insertion plates near the insertion end are beveled, a slot is provided on one side of each of the two insertion plates, a limit ring is fixedly connected to the outer surface of the male end, and both insertion plates are slidably inserted into the limit ring.
[0006] A mating ring is fixedly connected to the outer surface of the female end. The mating ring and the female end are on the same axis. Two symmetrically arranged U-shaped mating blocks are fixedly connected to the outer surface of the mating ring. A plug is inserted into one side of each of the two U-shaped mating blocks. The end of the plug near the female end is rounded. A spring is fixedly installed between the other end of the plug and the U-shaped mating block.
[0007] Furthermore, both the insertion end of the male end and the mating end of the female end are designed with foolproof features.
[0008] The above method ensures that the connection can only be made at one correct angle.
[0009] Furthermore, both the male and female ends, which are close to each other, are fixedly connected with sealing rings.
[0010] The above solution allows the insertion plate to pull the limiting ring, which in turn causes the two sealing rings to undergo axial compression deformation, thereby improving their sealing performance and preventing external liquid moisture from entering the internal electrical contact area of the connector.
[0011] Furthermore, a set of equally spaced anti-slip annular grooves are provided on the outer surfaces of both the male and female ends.
[0012] The above solution increases the coefficient of friction between the operator's hand and the outer surface of the connector, making it easier for the user to insert and remove the connector.
[0013] Furthermore, a moisture-proof ring is installed on the inner wall of the insertion end of the male end.
[0014] The above method utilizes the microporous structure of activated carbon materials to adsorb intruding moisture and corrosive gases.
[0015] Furthermore, the outer surface of the threaded sleeve is knurled.
[0016] The above solution increases the friction coefficient between the operator's hand and the threaded sleeve by pressing textures onto the metal surface, making it easier for the user to rotate.
[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0018] This type of electrical connector with an anti-slip structure, through the setting of the threaded sleeve, can pull the insertion plate and connecting plate to move, thereby realizing the secondary tightening function after the male end and the female end are connected. It achieves the effect of maintaining high connection strength under vibration or dynamic load, effectively solving the problem of fatigue and loosening of traditional snap-fit connectors. The inclined extrusion snap-fit design of the insertion plate and the U-shaped mating block achieves the purpose of mechanical self-locking, which can resist the effect of accidental pull-out force and significantly improve the reliability of the connector under complex working conditions. Through the bidirectional extrusion compression deformation of the sealing ring, the protection performance against liquids and moisture is greatly enhanced. The set activated carbon moisture-proof ring achieves the active interception of intruding water vapor and corrosive gases, which can delay the oxidation and corrosion of internal metal parts and extend the service life of the connector in harsh environments.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0027] Please see Figure 1 , Figure 2 and Figure 3 An electrical connector with an anti-slip structure in this embodiment includes a male end 1 and an insertion end 101 at one end, and a female end 2 and a mating end 201 at one end. The insertion end 101 of the male end 1 and the mating end 201 of the female end 2 are both designed to prevent mistaken insertion, ensuring that they can only be inserted at the one correct angle.
[0028] Please see Figure 1 , Figure 2 and Figure 3 A threaded post 3 is fixedly connected to the outer surface of the male end 1. The threaded post 3 and the male end 1 are on the same axis. A threaded sleeve 4 is threadedly connected to the outer surface of the threaded post 3. A connecting plate 5 is rotatably connected to the end of the threaded sleeve 4 near the insertion end 101. An insertion plate 6 is fixedly connected to the side of the connecting plate 5 near the insertion end 101. The edges of the two insertion plates 6 near the insertion end 101 are beveled. A slot 7 is opened on one side of each of the two insertion plates 6. A limit ring 8 is fixedly connected to the outer surface of the male end 1. Both insertion plates 6 are slidably inserted into the limit ring 8. The outer surface of the threaded sleeve 4 is knurled. By pressing the texture on the metal surface, the friction coefficient between the operator's hand and the threaded sleeve 4 is increased, making it easier for the user to rotate.
[0029] Please see Figure 1 , Figure 2 and Figure 4 A mating ring 9 is fixedly connected to the outer surface of the female end 2. The mating ring 9 and the female end 2 are on the same axis. Two symmetrically arranged U-shaped mating blocks 10 are fixedly connected to the outer surface of the mating ring 9. A plug rod 11 is inserted into one side of each of the two U-shaped mating blocks 10. The end of the plug rod 11 near the female end 2 is rounded. A spring 12 is fixedly installed between the other end of the plug rod 11 and the U-shaped mating block 10. When the male end 1 and the female end 2 are inserted and mated, the insertion plate 6 can squeeze the plug rod 11 to make room, so that it enters the slot 7 and completes the locking. Then, by rotating the threaded sleeve 4, the connecting plate 5 and the insertion plate 6 are moved. Under the limit of the limiting ring 8, the insertion plate 6 pulls the limiting ring 8 and the female end 2 to move along their axis, thereby improving the connection tightness of the male end 1 and the female end 2.
[0030] Please see Figure 1 , Figure 2 and Figure 3 Both the male end 1 and the female end 2 are fixedly connected to a sealing ring 13 at their closest points. By pulling the limiting ring 8 with the insertion plate 6, the two sealing rings 13 can undergo axial compression deformation, thereby improving their sealing performance and preventing external liquid moisture from entering the internal electrical contact area of the connector. Both the male end 1 and the female end 2 have a set of equally spaced anti-slip annular grooves 14 on their outer surfaces to increase the friction coefficient between the operator's hand and the outer surface of the connector, making it easier for the user to insert and remove the connector. A moisture-proof ring 15 is installed on the inner wall of the insertion end 101 of the male end 1. The moisture-proof ring 15 is made of activated carbon material, which uses the microporous structure of activated carbon material to adsorb intruding moisture and corrosive gases.
[0031] The working principle of the above embodiment is as follows: The operator inserts the male end 101 into the female end 201. Since both the male end 101 and the female end 201 are equipped with anti-foolproof structures, they can only be inserted at the correct angle to avoid damage to the electrical contact points due to misoperation. During the insertion process, the inclined structure at the front end of the insertion plate 6 first contacts the rounded end of the insertion rod 11 inside the U-shaped mating block 10. The inclined surface squeezes the insertion rod 11 to overcome the elastic force of the spring 12 and retract it into the U-shaped mating block 10, making room for the insertion plate 6 to insert. When the insertion plate 6 is fully inserted into the bottom of the U-shaped mating block 10, the insertion rod 11 is reset under the action of the spring 12, and its rounded end is locked into the slot 7 on the side of the insertion plate 6, forming a preliminary mechanical lock to prevent the male end 1 from accidentally disengaging from the female end 2. The operator rotates the threaded sleeve 4. Since the threaded sleeve 4 and the threaded post 3 are locked together, the threaded sleeve 4 and the threaded post 3 are locked together. Through the threaded connection, the threaded sleeve 4 pulls the connecting disc 5, causing the insertion plate 6 to move synchronously. The insertion plate 6 is constrained by the axial sliding of the limiting ring 8, and its displacement is converted into a pulling force on the limiting ring 8. This causes a controllable axial compression at the electrical contact interface between the male end 1 and the female end 2, significantly improving the connection tightness and effectively resisting loosening caused by vibration or pulling. During the axial tightening process, the sealing rings 13 at the ends of the male end 1 and the female end 2 undergo axial compression deformation due to relative movement, forming a radial sealing barrier to prevent liquid from penetrating radially along the contact surface. The activated carbon moisture-proof ring 15 on the inner wall of the insertion end 101 of the male end 1 continuously adsorbs moisture and corrosive gases that invade the inside of the connector through the microporous structure, forming a chemical adsorption protective layer. When it is necessary to separate the male end 1 and the female end 2, it is only necessary to pull out the plug 11 to separate it from the slot 7, thereby achieving the separation of the male end 1 and the female end 2.
