Description

Technical Field

[0001] This application relates to the field of cable connector technology, specifically to a cable connector that is easy to plug in and unplug. Background Technology

[0002] Cable connectors are widely used in the assembly of electronic products, and they are key products to ensure the correctness and reliability of electrical signal transmission.

[0003] An existing patent (publication number: CN209217269U) discloses a cable connector, including a base, which solves the problem that the cable is prone to loosening and damage at the connector connection when subjected to external bending force. The base is provided with a top cover, and a first connector and a second connector are provided on the base. A mating unit is provided between the first connector and the second connector for docking and fixing. Both the first connector and the second connector are provided with fixing units for fixing to the base. The base is also provided with a fastening device, which is connected and fixed to the cable. By setting the base and fixing units to fix the first connector and the second connector, the cable is distributed and connected to the first connector and the second connector. The first connector and the second connector are fixed to each other to realize the cable connection. At the same time, the fastening device tightly fastens to the cable, which strengthens the strength of the entire device and prevents the cable from detaching due to external force.

[0004] The aforementioned connectors are fastened to the cables by a fastening device, which strengthens the overall strength of the device and prevents the cables from coming off due to external forces. However, some equipment needs to be moved, and the length of the cables may be limited during the movement. The aforementioned cable connectors are not easy to separate after connection and have poor flexibility. Utility Model Content

[0005] In view of the shortcomings of the prior art, this application provides a cable connector that is easy to plug and unplug, and has the advantages of one-handed separation, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a cable connector that is easy to insert and remove, comprising a male component and a female component, wherein the male component and the female component respectively include a male sleeve and a female sleeve, an annular limiting groove is provided on the inner wall of the female sleeve near the male sleeve, a plurality of circumferentially arranged cavities are provided on the male sleeve near the female sleeve, a connecting rod is provided inside each cavity, a locking block is fixedly connected to the left end of each connecting rod, each locking block is slidably inserted along the radial direction of the male sleeve, the right end of each connecting rod is slidably inserted along the radial direction of the male sleeve, a compression ball is fixedly connected to the top of the right end of each connecting rod, a spring is installed between each compression ball and the male sleeve, the spring is sleeved with the right end of the adjacent connecting rod, and a reset ring is fixedly connected to the outer surface of the male sleeve;

[0007] The outer surface of the male sleeve is slidably fitted with a separation sleeve. A compression spring is fixedly installed between the right inner sidewall of the separation sleeve and the reset ring. The left inner sidewall of the separation sleeve has an arc-shaped cross-section, and its arc-shaped inner wall contacts each compression ball.

[0008] Furthermore, a terminal block is fixedly connected to the middle of the inner wall of both the male and female sleeves. Three terminal rods arranged in a circle are fixedly connected inside each of the two terminal blocks. The left end of the three terminal rods on the leftmost side and the right end of the three terminal rods on the rightmost side are fixedly connected to terminal lugs.

[0009] The above solution facilitates connection to the live, neutral, and ground wires in external cables.

[0010] Furthermore, the right ends of the three leftmost connecting rods are provided with connection holes, the left ends of the three rightmost connecting rods are rounded, and the outer surfaces of the three rightmost connecting rods are provided with a set of circumferentially arranged elastic pieces, each elastic piece being integrally formed with its adjacent connecting rod.

[0011] The above scheme utilizes the radial tension of the elastic sheet to form multi-point surface contact, which ensures both the conductive cross-sectional area and the self-locking and anti-loosening function.

[0012] Furthermore, cables are fixedly installed at the ends of the male and female sleeves that are far apart from each other, and the live wire, neutral wire and ground wire of each cable are respectively connected to their adjacent terminal lugs.

[0013] The above solution utilizes the crimping structure of the connector lug to achieve a reliable electrical connection between the cable core and the conductive rod, while the modular design enables the connector to have plug-and-play characteristics.

[0014] Furthermore, both the male and female sleeves are provided with a moisture-proof cavity at their middle ends. Each moisture-proof cavity has a set of circumferentially arranged vent holes on its inner wall, and each moisture-proof cavity is filled with porous silica gel desiccant particles.

[0015] The above solution utilizes vents to create air convection channels, allowing desiccant particles to continuously absorb intruding moisture and construct a moisture barrier to protect internal conductive components.

[0016] Furthermore, the side of each card block away from the male sleeve is set as a slope that is lower on the left and higher on the right.

[0017] Through the above scheme, the inclined guide design enables the automatic compression of the locking block when the male sleeve is inserted, realizing one-handed blind insertion operation. When separating, the inclined surface and the annular limiting groove form a mechanical wedge effect to enhance the holding force.

[0018] Furthermore, the outer surface of the separating sleeve is provided with an anti-slip texture.

[0019] The above method increases the coefficient of friction during operation, ensuring that precise separation can still be achieved even when wearing insulating gloves.

[0020] Furthermore, both the male and female sleeves have a replacement head threadedly connected to their opposite ends, and the inner wall of the replacement head is provided with a sealing ring.

[0021] The above scheme and settings allow for the replacement of the head according to different cable diameters, thus making it suitable for cables of different diameters.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This easy-to-plug cable connector features a beveled guide design with a male sleeve retaining block and a female sleeve annular limiting groove, enabling one-handed blind insertion. During insertion, the edge of the female sleeve automatically compresses the retaining block, and after insertion, a spring drives the retaining block to reset and lock. During separation, only one finger needs to pull the anti-slip separation sleeve, and the arc-shaped inner wall drives the compression ball to retract the retaining block, effectively improving assembly and disassembly efficiency. The connector adopts an interference fit design between the elastic sheet and the connection hole. When the male and female parts are mated, the elastic sheet contracts radially, and after insertion, it elastically recovers to form multi-point surface contact, effectively resisting the risk of contact failure under vibration conditions.

[0032] 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.

[0033] Please see Figure 1 , Figure 2 and Figure 3 This embodiment provides a cable connector that is easy to plug and unplug, including a male component 1 and a female component 2. The male component 1 and the female component 2 each include a male sleeve 101 and a female sleeve 201. The inner wall of the female sleeve 201 near the male sleeve 101 is provided with an annular limiting groove 202. The male sleeve 101 near the female sleeve 201 is provided with a plurality of circumferentially arranged cavities 102. Each cavity 102 is provided with a connecting rod 103. The left end of each connecting rod 103 is fixedly connected to a locking block 104. Each locking block 104 is slidably inserted into the male sleeve 101 radially. The right end of each connecting rod 103 is slidably inserted into the male sleeve 101 radially. The top of the right end of each connecting rod 103 is fixedly connected to a compression ball 105. A spring 106 is installed between each compression ball 105 and the male sleeve 101. The spring 106 is sleeved with the right end of its adjacent connecting rod 103. A reset ring 107 is fixedly connected to the outer surface of the male sleeve 101.

[0034] Please see Figure 2 , Figure 3 and Figure 4 Both male sleeve 101 and female sleeve 201 have a terminal block 3 fixedly connected to their inner wall center. The terminal block 3 is made of insulating material. Inside each of the two terminal blocks 3, three terminal rods 4 arranged in a circle are fixedly connected. The left end of the three leftmost terminal rods 4 and the right end of the three rightmost terminal rods 4 are fixedly connected to terminal lugs 5. This arrangement facilitates connection with the live wire, neutral wire, and ground wire in external cables. The right end of the three leftmost terminal rods 4 is provided with a connection hole 6, and the left end of the three rightmost terminal rods 4 is rounded. The corner is set, and the outer surface of the three rightmost connecting rods 4 is provided with a set of elastic plates 7 arranged in a circle. Each elastic plate 7 is integrally formed with its adjacent connecting rod 4. When the male part 1 and the female part 2 are connected, the three right connecting rods 4 are inserted into the connecting hole 6. The left end of the right connecting rod 4 contacts the inner bottom wall of the connecting hole 6. At the same time, the elastic plate 7 is in close contact with the inner wall of the connecting hole 6, which can achieve the purpose of conducting electricity. Through the above arrangement, the radial tension of the elastic plate 7 is used to form multi-point surface contact, which not only ensures the conductive cross-sectional area, but also achieves the self-locking and anti-loosening function.

[0035] Please see Figure 1 , Figure 2 and Figure 3The male sleeve 101 is slidably fitted with a separating sleeve 108. A compression spring 109 is fixedly installed between the right inner sidewall of the separating sleeve 108 and the reset ring 107. The left inner sidewall of the separating sleeve 108 has an arc-shaped cross-section, and its arc-shaped inner wall contacts each compression ball 105. With the above arrangement, when the male sleeve 101 is inserted into the female sleeve 201, the right edge of the female sleeve 201 compresses the locking block 104, causing the locking block 104 to enter the cavity 102. When the locking block 104 reaches the annular limiting groove 202, it loses pressure and engages with the annular limiting groove 202, completing the quick connection. When it is necessary to separate the male part 1 and the female part 2, by pulling the separating sleeve 108 to the right, the arc-shaped inner wall of the separating sleeve 108 compresses the compression ball 105, which in turn drives the locking block 104 into the cavity 102 through the connecting rod 103, releasing the limitation with the annular limiting groove 202, thereby achieving the purpose of quick insertion and removal.

[0036] Please see Figure 1 , Figure 2 and Figure 3 Both male sleeve 101 and female sleeve 201 have cables 8 fixedly installed at their far ends. The live wire, neutral wire, and ground wire of each cable 8 are connected to their adjacent lugs 5. The crimping structure of the lugs 5 ensures a reliable electrical connection between the core wires of the cable 8 and the conductive rod. The modular design allows the connectors to be plug-and-play. Both male sleeve 101 and female sleeve 201 have a moisture-proof cavity 9 at their middle ends. Each moisture-proof cavity 9 has a set of circumferentially arranged vent holes 10 on its inner wall. Each moisture-proof cavity 9 is filled with porous silica gel desiccant particles. The vent holes 10 create air convection channels, allowing the desiccant particles to continuously absorb intruding moisture, thus constructing a moisture barrier to protect the internal conductive parts. The component has a beveled surface on the side of each locking block 104 away from the male sleeve 101, with the left side lower than the right side. The beveled guide design allows the locking block 104 to be automatically compressed when the male sleeve 101 is inserted, enabling one-handed blind insertion. When separating, the beveled surface and the annular limiting groove 202 form a mechanical wedge effect to enhance the holding force. The outer surface of the separating sleeve 108 is textured with anti-slip material to increase the coefficient of friction during operation, ensuring accurate separation even when wearing insulated gloves. The ends of the male sleeve 101 and the female sleeve 201 that are away from each other are threaded with a replacement head 11. The inner wall of the replacement head 11 is provided with a sealing ring 12. Through the above settings, the replacement head 11 can be replaced according to the different diameters of the cable 8, thus making it suitable for cables of different diameters.

[0037] The working principle of the above embodiment is as follows: The operator holds the male sleeve 101 with one hand and inserts it with the front end aligned with the opening of the female sleeve 201. The right edge of the female sleeve 201 first contacts the inclined surface of the locking block 104, generating an axial force that forces the locking block 104 to retract radially into the cavity 102 along the male sleeve 101. During the insertion of the male sleeve 101, the three connecting rods 4 with elastic pieces 7 on the female sleeve 201 terminal block 3 are gradually inserted into the connection holes 6 opened on the connecting rods 4 of the male sleeve 101 terminal block 3. After being inserted into place, the elastic pieces 7 restore their deformation and form multiple contact points with the inner wall of the connection holes 6 to ensure a conductive path. When the ambient humidity changes, the moisture-proof cavity 9 is connected to the outside through the vent holes 10. Micro-air exchange, porous silica gel desiccant particles absorb intruding moisture, and the sealing ring 12 on the inner wall of the replacement head 11 can be replaced with a replacement head 11 with a different inner diameter when replacing cables 8 of different diameters. During separation, the operator pulls the separation sleeve 108, which overcomes the resistance of the compression spring 109 and slides axially along the male sleeve 101. Its arc-shaped inner wall forms a wedge fit with the extrusion ball 105, converting the axial tension into radial extrusion force. After being compressed, the extrusion ball 105 pushes the connecting rod 103, causing the locking block 104 to fully retract into the cavity 102, releasing the mechanical connection with the annular limiting groove 202, and achieving rapid separation.
