Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and in particular to a quick-installation spring connector. Background Technology

[0002] Spring connectors are a type of electrical connection device that uses the elastic force of elastic elements to clamp, fix and conduct wires. Its core feature is that it relies on springs or elastic metal parts to generate continuous pressure, so that the wires and conductive parts maintain reliable contact, without the need to fix the wires by traditional methods such as screws or welding.

[0003] In the assembly process of existing spring-type connectors, the conductive springs are difficult to install and are not easy to align, resulting in low assembly efficiency. The conductive springs may shift or become loose, which affects the stability and safety of the wiring and increases the difficulty of assembly and maintenance. Utility Model Content

[0004] The purpose of this invention is to provide a quick-installation spring connector, in which the conductive spring can be quickly inserted into the wiring cavity and accurately positioned and reliably fixed, thereby completing a fast and stable installation.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a quick-installation spring connector, comprising a housing, at least one wiring cavity disposed within the housing, a conductive spring disposed within the wiring cavity, a busbar electrically connected to the conductive spring, and a button structure disposed on the housing. One end of the housing is provided with an inlet communicating with the wiring cavity, and the other end is provided with an installation port allowing the conductive spring to pass through. The button structure is provided with a downwardly extending limiting post, and the conductive spring is provided with a corresponding limiting hole. The limiting post and the limiting hole are inserted into each other.

[0006] By adopting the above technical solution, the conductive spring can be smoothly inserted into the wiring cavity through the installation port, and the positioning and fixing are completed by the plugging and matching of the limiting post and the limiting hole, thereby achieving fast and stable installation.

[0007] The present invention is further configured such that: the conductive spring includes a raised portion at the end, the middle of the end face of the raised portion extends upward to form a pressing protrusion, a wire-passing notch is formed between the two sides of the pressing protrusion and the upper end face of the raised portion, the button structure presses and cooperates with the pressing protrusion to drive the raised portion to elastically press down into the wiring cavity, and to make the wire-passing notch communicate with the wiring cavity.

[0008] By adopting the above technical solution, under the drive of the button structure, the raised part of the conductive spring is deformed, and the wire-passing gap between it and the busbar is enlarged, so that the wire can be easily inserted or pulled out from the inlet.

[0009] The present invention is further configured such that: the button structure includes a pressing part and a plug-in part at both ends; a pressing part is provided below the pressing part; a slot is provided on the outer shell; a pressing protrusion is provided at one end of the conductive spring; the pressing part passes through the slot and abuts against the pressing protrusion; the plug-in part is installed on the outer shell by an anti-disengagement structure.

[0010] By adopting the above technical solution, the action of the pressing part can be directly applied to the pressing protrusion of the conductive spring through the pressing part. When the pressing protrusion is pressed down, a wiring gap is formed on both sides of the pressing protrusion for the wire to pass through. The plug part is fixed to the outer shell by the anti-disengagement structure, so that the button structure is not easy to loosen during frequent operation, thus improving the reliability of the structure.

[0011] The present invention is further configured such that: the anti-detachment structure includes a limiting block disposed below the insertion part, the limiting post is disposed on the limiting block, the outer shell is provided with a mounting boss, the mounting boss is provided with a mounting groove, and the limiting block is inserted into the mounting groove.

[0012] By adopting the above technical solution, the insertion and engagement of the limiting block and the mounting groove can form a stable installation and positioning structure, ensuring that the button structure is reliably fixed inside the housing and avoiding loosening or displacement due to external forces.

[0013] The present invention is further configured such that: the limiting block is provided with a first buckle, and the first buckle forms a stop engagement with the outer periphery of the mounting groove.

[0014] By adopting the above technical solution, the first buckle can provide a further stopping function after being inserted into the mounting slot, thereby preventing the limit block from retracting and improving the installation strength.

[0015] The present invention is further configured such that: the inner wall of the mounting boss is provided with an avoidance groove that allows the first buckle to pass through.

[0016] By adopting the above technical solution, the clearance groove can provide a clearance channel for the first buckle during the installation process, so that the limit block can be smoothly inserted into the installation groove, thus improving the convenience of assembly.

[0017] The present invention is further configured such that: the clearance groove is provided with a lower mounting slope, the first buckle is provided with a corresponding upper mounting slope, and the upper mounting slope and the lower mounting slope abut against each other.

[0018] By adopting the above technical solution, the inclined surface between the buckle and the clearance groove can play a guiding role during the insertion process, so that the buckle can slide in smoothly and finally be locked, which is convenient for installation and ensures that the positioning is reliable.

[0019] The present invention is further configured such that: the pressing part is provided with a limiting protrusion, and the limiting protrusion and the pressing protrusion form a stop cooperation.

[0020] By adopting the above technical solution, the limiting protrusion can effectively limit the displacement range of the conductive spring, avoid excessive pressing that could cause the pressing protrusion to loosen, and ensure safety during use.

[0021] The present invention is further configured such that: a second buckle is provided on the limiting protrusion, and the second buckle forms a stop engagement with the outer periphery of the slot.

[0022] By adopting the above technical solution, the second buckle can cooperate with the outer periphery of the slot when the pressing part is reset, further improving the stability of the button structure and preventing it from loosening.

[0023] The present invention is further configured such that: the busbar is provided with a stepped portion, and the stepped portion forms a limiting fit with the outer shell.

[0024] By adopting the above technical solution, the stepped portion can form a limiting effect between the busbar and the housing, further preventing the busbar from shifting under external force and maintaining the stability of the electrical connection.

[0025] In summary, this utility model has the following beneficial effects: 1. The conductive spring of this utility model can be smoothly inserted into the wiring cavity through the installation port, and can be accurately positioned and reliably fixed through the plug-in cooperation of the limiting post and the limiting hole, thereby completing a fast and stable installation.

[0026] 2. Multiple anti-detachment mechanisms between the button structure and the housing prevent loosening or detachment during frequent operation; the stepped section between the busbar and the housing also provides a limit, ensuring the reliability of the overall connection.

[0027] 3. By using the beveled fit between the clearance groove and the first buckle, smooth insertion can be achieved during the assembly process, reducing the difficulty of assembly. Attached Figure Description

[0034] The present invention will be further described below with reference to the accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, the present invention provides a quick-installation spring connector, comprising a housing 1, at least one wiring cavity 11 disposed within the housing 1, a conductive spring 2 disposed within the wiring cavity 11, a busbar 3 electrically connected to the conductive spring 2, and a button structure 4 disposed on the housing 1. Each wiring cavity 11 has a wire inlet 12 and a mounting port 13 at both ends. The wire inlet 12 corresponds to an external wire, facilitating direct insertion or removal of the wire. The mounting port 13 communicates with the wiring cavity 11, and its size design allows the conductive spring 2 to be smoothly inserted and positioned.

[0036] like Figure 3 As shown, the conductive spring 2 is an elastic metal component with an arc-shaped bend. The conductive spring 2 includes a raised portion 23 at the end. The middle of the end face of the raised portion 23 extends upward to form a pressing protrusion 22. A wire-passing notch 24 is formed between the two sides of the pressing protrusion 22 and the upper end face of the raised portion 23. The button structure 4 presses and engages with the pressing protrusion 22, causing the raised portion 23 to be elastically pressed down into the wiring cavity 11, and connecting the wire-passing notch 24 with the wiring cavity 11. The busbar 3 is close to the inner wall of the housing 1, and one end extends to the outside of the mounting port 13. A conductive clip 31 is provided at the end to make reliable electrical contact with the external circuit or the busbar 3 bus. A step portion 32 is provided between the busbar 3 and the housing 1. The step portion 32 and the housing 1 form a limiting engagement to prevent the busbar 3 from displacing when subjected to external force, thus ensuring the stability of the electrical connection.

[0037] like Figure 4As shown, the button structure 4 includes a pressing part 41 and a plugging part 42 located at both ends. A pressing part 44 is provided below the pressing part 41. The pressing part 44 is connected to the lower part of the pressing part 41. The pressing part 44 passes through the slot 14 opened on the outer shell 1 and directly abuts against the pressing protrusion 22 of the conductive spring 2. When pressed, the force can be effectively transmitted to the spring. The anti-dislodgement structure includes a limiting block 45 located below the plugging part 42. The outer shell 1 is provided with a mounting protrusion 15. The limiting block 45 is inserted into the mounting groove 16 in the mounting protrusion 15 and forms a stop cooperation with the outer periphery of the mounting groove 16 through the first buckle 451, thereby ensuring that the button structure 4 will not be loosened due to frequent operation during use. The limiting block 45 is provided with a downwardly extending limiting post 43. The middle part of the conductive spring 2 is provided with a corresponding limiting hole 21. The limiting post 43 is plugged into the limiting hole 21 to prevent the conductive spring 2 from being loosened.

[0038] like Figures 1 to 5 As shown, the outer shell 1 is provided with a mounting boss 15, and a mounting groove 16 is provided inside the mounting boss 15. The limiting block 45 is inserted into the mounting groove 16. An avoidance groove 151 is provided on the inner wall of the mounting groove 16. The interior of the avoidance groove 151 is designed with a lower mounting slope 1511, which cooperates with the upper mounting slope 4511 of the first buckle 451. During the insertion process, it provides guidance for the buckle, allowing it to slide in smoothly and finally lock, simplifying the installation process and improving the reliability of the assembly.

[0039] The surface of the pressing part 41 is provided with a limiting protrusion 441, which forms a stop with the pressing protrusion 22 of the conductive spring 2, preventing the conductive spring 2 from being permanently deformed or loosened due to excessive pressure. A second buckle 4411 is also provided on the limiting protrusion 441, which forms a stop with the outer periphery of the slot 14, so that the button structure 4 can remain firmly positioned when reset, avoiding the risk of loosening due to external impact or long-term operation.

[0040] like Figure 5 As shown, the design of each wiring cavity 11 allows for at least two mounting ports 13, which can accommodate two wires of different diameters to be connected at the same time, thereby meeting different wiring requirements.

[0041] The basic working principle of this utility model is as follows: During installation, the conductive spring 2 is inserted into the wiring cavity 11 through the mounting port 13 at one end of the outer shell 1. The limiting post 43 is inserted and positioned with the limiting hole 21 on the conductive spring 2, so that the conductive spring 2 is stably fixed in the wiring cavity 11. The busbar 3 is reliably held in the predetermined position through its stepped part 32 and the limiting cooperation with the outer shell 1, maintaining an electrical connection with the conductive spring 2. During the wiring stage, the user inserts the wire to be connected from the inlet port 12 at the other end of the outer shell 1, and at the same time presses the button structure 4 on the surface of the outer shell 1. When the button moves down, it drives the pressing part 44 to move downward. The pressing part 44 moves straight down. The pressing protrusion 22 of the conductive spring 2 is applied, causing the raised part 23 of the conductive spring 2 to elastically deform, move away from the busbar 3, and widen the wire insertion gap 24. In this state, the wire smoothly slides into the space between the conductive spring 2 and the busbar 3. After the button structure 4 is released, the conductive spring 2 returns to its original position under its own elastic force, presses the wire, and forms a stable electrical contact with the busbar 3, achieving a firm conductive connection. During the wire pulling stage, simply press the button structure 4 again, and the pressing part 44 pushes the conductive spring 2 down again, releasing the wiring gap, and the wire can be easily pulled out from the wire inlet 12. The entire operation does not require the use of tools.

[0042] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
