Description

Technical Field

[0001] This invention relates to the field of terminal blocks, and more particularly to a terminal block that is easy to plug in and unplug. Background Technology

[0002] Terminal blocks are commonly used for electrical connections, improving the convenience of wiring connections through plug-in connections. With the development of the electronics industry, the application of terminal blocks is becoming increasingly widespread.

[0003] During the use of terminal blocks, screws or screw sleeves can be installed to lock them in place to prevent the socket and plug from separating after plugging and unplugging. However, the installation and removal of screws is time-consuming, which affects the convenience of plugging and unplugging the terminal blocks. Moreover, screws are easy to lose during the installation and removal process, which affects subsequent use. Improvements are needed. Summary of the Invention

[0004] The purpose of this invention is to provide a terminal block that is easy to plug and unplug, allowing for quick plugging and locking, thereby improving the convenience of assembly and disassembly.

[0005] To achieve this objective, the present invention adopts the following technical solution: A plug-in / plug-out terminal block includes: a plug and a matching socket. The plug has conductive pins spaced apart at its front end. The socket has conductive sleeves corresponding to the conductive pins. Each conductive pin has a recessed first groove. After the conductive pin is inserted into the conductive sleeve, the first groove is located in front of the conductive sleeve within the socket. The socket has a V-shaped spring piece located on one side of the conductive sleeve with its opening pointing forward. The socket also has stops on both sides of the tip of the V-shaped spring piece. The V-shaped spring piece has a first arc-shaped flange located on the front side of the conductive socket near one end. A locking block corresponding to the first slot is provided on the outer side of the first arc-shaped flange. A positioning post is inserted into the first arc-shaped flange inside the wiring socket. A second arc-shaped flange is provided on the other end of the V-shaped spring piece. A sliding groove is provided in the wiring plug. A lever is provided in the sliding groove. An insert extending to the front of the wiring plug and parallel to the conductive pin is provided in the lever. A second slot corresponding to the second arc-shaped flange is provided on the side of the insert.

[0006] The conductive socket has symmetrically arranged rearward-extending square grooves at its front end.

[0007] The positioning post is provided with a first mounting hole.

[0008] The stop block is provided with a second mounting hole.

[0009] The locking block has a cylindrical structure.

[0010] The first slot is an annular groove, and the second slot is a V-shaped groove.

[0011] The insert has a chamfered front end.

[0012] During the process of inserting the conductive pin into the conductive sleeve, the insert is pushed forward by the lever and comes into contact with the second arc-shaped flange. The insert drives the V-shaped spring to flip towards the conductive sleeve, forcing the locking block into the first slot. The second arc-shaped flange then enters the second slot to achieve self-locking.

[0013] The front end of the wiring socket is provided with a guide sleeve that corresponds to each of the conductive pins.

[0014] The front end of the wiring socket is provided with a socket corresponding to the plug.

[0015] The beneficial effects of this invention are as follows: A terminal block that is easy to plug and unplug. During the plug-in and socket-in process, the V-shaped spring is driven by pushing the plug forward with a lever. The conductive pin is locked by the V-shaped spring and the locking block, which improves the stability after plugging and avoids the problem of loosening. When disassembling, the plug is pulled outward by the lever. The V-shaped spring loses the limit of the plug and releases the limit of the locking block on the conductive pin, which facilitates the plug-in to be pulled out. No screws are required for disassembly and assembly, and the operation is simple. Attached Figure Description

[0016] Figure 1 This is a schematic diagram of the structure of the present invention; Figure 2 yes Figure 1 A schematic diagram of the structure after the connector plug and connector socket are separated. Detailed Implementation

[0017] The following is combined Figures 1 to 2 The technical solution of the present invention will be further illustrated through specific embodiments.

[0018] like Figure 1 and Figure 2 The connector shown includes a connector plug 2 and a matching connector socket 1. The connector plug 2 has conductive pins 14 spaced apart at its front end. The connector socket 1 has a guide sleeve 7 at its front end that corresponds one-to-one with the conductive pins 14, which facilitates the guidance during insertion.

[0019] The wiring socket 1 is provided with conductive sleeves 9 corresponding to the conductive pins 14 one by one. In this embodiment, the conductive pins 14 and the conductive sleeves 9 are interference-fitted, and the electrical connection is stable. The front end of the conductive sleeve 9 is symmetrically provided with rearwardly extending square grooves 10, which facilitates the elastic expansion of the conductive sleeve 9 when the conductive pins 14 are inserted, and the conductive sleeves 9 achieve elastic clamping of the conductive pins 14.

[0020] like Figure 2 As shown, the conductive pin 14 has a recessed first slot 15, which in this embodiment is an annular slot. Figure 1 As shown, after the conductive pin 14 is inserted into the conductive sleeve 9, the first slot 15 is located in front of the conductive sleeve 9 inside the wiring socket 1, which facilitates locking.

[0021] A V-shaped spring piece 3 is provided inside the wiring socket 1, located on one side of the conductive sleeve 9 with its opening pointing towards the front of the wiring socket 1. The V-shaped spring piece 3 can be made of an elastic metal material with good elasticity. The wiring socket 1 is provided with a stop block 12 and a stop post 11 located on both sides of the tip of the V-shaped spring piece 3 to limit the left and right rotation of the tip of the V-shaped spring piece 3.

[0022] A first arc-shaped flange 6 is provided at one end of the V-shaped spring piece 3 near the conductive sleeve 9, located on the front side of the conductive sleeve 9. A positioning post 4 is provided inside the wiring socket 1, which is inserted into the first arc-shaped flange 6 to position the first arc-shaped flange 6, so that the V-shaped spring piece 3 swings around the positioning post 4 as the center. In addition, a first mounting hole is provided in the positioning post 4, and a second mounting hole 13 is provided on the stop block 12 to facilitate the assembly of the wiring socket 1 housing.

[0023] like Figure 1 As shown, a locking block 8 corresponding to the first slot 15 is provided on the outer side of the first arc flange 6. In this embodiment, the locking block 8 adopts a cylindrical structure, which fits tightly with the first slot 15 and has good self-locking performance after insertion.

[0024] A second arc-shaped flange 5 is provided at the other end of the V-shaped spring 3. A sliding groove 19 is provided in the connector 2. A lever 18 is provided in the sliding groove 19. A plug 17 is provided in the lever 18, extending to the front of the connector 2 and parallel to the conductive pin 14. The plug 17 can be made of insulating plastic material for safe operation.

[0025] A second slot 16 corresponding to the second arc-shaped flange 5 is provided on the side of the insert 17. In this embodiment, the second slot 16 is a V-shaped slot to facilitate engagement with the second arc-shaped flange 5. For easy insertion, a chamfer is provided at the front end of the insert 17, and a corresponding socket hole is provided at the front end of the wiring socket 1 for easy insertion. During the process of inserting the conductive pin 14 into the conductive sleeve 9, the operator's thumb pushes the insert 17 forward through the lever 18 to contact the second arc-shaped flange 5. The insert 17 drives the V-shaped spring 3 to flip towards the conductive sleeve 9, forcing the locking block 8 into the first slot 15 to axially lock the conductive pin 14. The second arc-shaped flange 5 then enters the second slot 16 to achieve self-locking, preventing the insert 17 from moving outward at will.

[0026] During disassembly, the insert 17 is pulled outward by the lever 18, and the V-shaped spring 3 loses the limit of the insert and releases the lock block 8 from the limit of the conductive pin 14, which makes it easier to pull out the connector 2. Moreover, no screws are required to disassemble or assemble during the plugging and unplugging process, making the operation simpler.

[0027] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
