Abstract
Description
Technical Field
[0001] This utility model relates to the field of plug technology, specifically to a plug that is easy to assemble and disassemble. Background Technology
[0002] Existing plugs mainly consist of a lower shell and a top cover. Most of these use a straight-cover connection, requiring users to loosen the top cover screws and place it aside during wiring. However, the top cover is easily lost during wiring or maintenance. Furthermore, the use of pull-tab terminals during wiring means that the force applied to the terminal screws can easily deform the pin, affecting its subsequent use. Utility Model Content
[0003] The technical problem this invention aims to solve is that straight-cap plugs are inconvenient to maintain, components are easily lost during maintenance, and the tail of the pin is easily deformed, affecting subsequent use.
[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a plug that is easy to assemble and disassemble, including a lower shell and an upper cover that cooperate with each other. The upper cover and the lower shell are hinged at one end, and the upper cover and the lower shell cooperate to form a wiring cavity. One end of the wiring cavity is provided with a through hole for cable to be inserted, and the other end is provided with a plug. The lower shell is provided with fasteners on both sides near the plug for stable fastening of the cable.
[0005] Furthermore, the lower shell has hinge posts on both sides of its top, and the upper cover has hinge grooves that mate with the hinge posts.
[0006] Furthermore, the semi-circular end face of the hinged column is chamfered to form a guide chamfer.
[0007] Furthermore, the fastener includes an inner pressure block that can be connected to the lower shell for positioning. A terminal block is slidably provided between the inner pressure block and the lower shell. A pin is slidably provided inside the terminal block. A terminal screw is provided on the pin that is threadedly engaged with the terminal block. The terminal screw extends out of the inner pressure block.
[0008] Furthermore, the lower shell is provided with guide ribs on both sides of the wiring terminal, the wiring terminal slides between the guide ribs, and the lower shell is provided with support ribs below the wiring terminal.
[0009] The advantages of this utility model compared with the prior art are as follows:
[0010] 1. The hinged design of the lower shell and upper cover allows for a flip-type rotating fit, facilitating wiring and maintenance while preventing component loss; the hinged installation of the lower shell and upper cover ensures that the damaged surface is located on the inside, maintaining an aesthetically pleasing appearance.
[0011] 2. The fasteners facilitate stable positioning of the cable conductors, ensuring the stability of the plug during use. Attached Figure Description

[0017] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0018] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 3 A plug that is easy to assemble and disassemble includes a lower shell 1 and an upper cover 2 that cooperate with each other. The upper cover 2 and the lower shell 1 are hinged at one end. The lower shell 1 has hinge posts 5 on both sides of its top. The free end face of the hinge post 5 is chamfered into a guide chamfer. The upper cover 2 has hinge grooves 6 that cooperate with the hinge posts. The upper cover 2 and the lower shell 1 cooperate to form a wiring cavity 3. One end of the wiring cavity 3 has a through hole for cable to be inserted, and the other end has a plug core 4.
[0019] Combined with appendix Figure 1 The existing plug mainly consists of a lower shell 1 and an upper cover 2. The lower shell 1 and the upper cover 2 are mostly connected by a straight cover. When wiring, people need to loosen the screws of the upper cover 2 and place it aside. During wiring or maintenance, the upper cover 2 is easy to lose.
[0020] The plug of this application adopts a flip-top connection. When wiring, after loosening the screws, the upper cover 2 is flipped around the hinge point with the lower shell 1, exposing the internal fasteners. This facilitates wiring and inspection and maintenance of the cable conductors. Wiring is convenient and quick, without the need to completely separate the upper cover 2 from the lower shell 1, and also avoids the loss of components during the maintenance of the upper cover 2.
[0021] However, most flip-top designs have a hinge post 5 on the upper cover 2 and a hinge groove 6 on the lower cover 1. During installation, the hinge post 5 of the upper cover 2 needs to be pressed down so that it is rigidly embedded into the hinge groove 6 of the lower cover 1 and cooperates with it to ensure that the upper cover 2 rotates smoothly and does not fall off. During this installation process, the hinge post 5 is prone to damaging the appearance of the lower cover 1, which often makes consumers both love and hate it, and it is a shortcoming.
[0022] To avoid affecting the appearance, this application provides a hinge groove 6 on the upper cover 2 and a hinge post 5 on the lower shell 1. During installation, the upper cover 2 is pressed down, causing the hinge post 5 of the lower shell 1 to be guided from the hinge groove 6 near the inside of the upper cover 2. This causes the plastic wear to shift from the outside to the inside, resulting in a more uniform and aesthetically pleasing appearance. The free end face of the hinge post 5 is chamfered into a guide chamfer, making it easier for the hinge post 5 to engage with the hinge groove 6 from the guide chamfer side, while also preventing step differences or damage that could affect its use.
[0023] Combined with appendix Figure 4 The lower shell 1 is provided with fasteners on both sides near the core 4 to stabilize and limit the position of the cable conductor. The fasteners include an inner pressure block 7 that can be connected to the lower shell 1 for limiting. The inner pressure block 7 is provided with a screw flange 8. A terminal screw 9 is rotatably passed through the screw flange 8. The terminal screw 9 passes through the inner pressure block 7 and has a pin 10 at its end between the inner pressure block 7 and the lower shell 1. A terminal 11 is slidably provided outside the pin 10.
[0024] Most of the fasteners use a pull-tab terminal wiring method. The pull-tab wiring method means that when the user inserts the wire into the terminal 11, he turns the terminal screw 9 clockwise. The screw flange 8 is held in place by the inner pressure block 7, and the bottom of the terminal screw 9 is held in place by the pin 10. The terminal screw 9 passes through the terminal 11 through the thread. By turning the terminal screw 9, the terminal 11 is moved upward, thereby pressing the wire and limiting it between the terminal 11 and the pin 10.
[0025] Combined with appendix Figure 4 The lower shell 1 is provided with guide ribs 12 on both sides of the terminal 11. The terminal 11 slides between the guide ribs 12, and the top of the guide ribs 12 abuts against the bottom of the screw flange 8.
[0026] In daily use, when tightening the terminal screw 9, there will be a downward force pressing against the pin 10. If the tail of the pin 10 lacks support, the tail of the pin 10 will deform, which will reduce the size of the wiring hole between the pin 10 and the terminal 11. This will make it difficult for wires to enter during subsequent wiring, and there will still be gaps when the screw is tightened, resulting in unstable wiring and easy detachment.
[0027] To prevent deformation of the tail of the plug 10 during use, which could affect subsequent wiring, this application uses a larger screw flange 8 and adds a guide rib 12 to increase the contact area between the screw flange 8 and the guide rib 12. This not only provides stable support for the screw flange 8 but also guides the terminal 11 through the guide rib 12. When tightening the terminal screw 9, the force on the terminal screw 9 is applied to the guide rib 12, ensuring that the plug 10 can be driven up and down while preventing deformation of the tail of the plug 10, thus extending the service life of the plug.
