Detailed Implementation

[0028] The present invention will now be further described in conjunction with the accompanying drawings and embodiments:

[0029] Example 1:

[0030] This embodiment provides the following: Figure 1-3 The diagram shows a quick-connect press-type connector, comprising a top cover 1, a plurality of conductive pins 2, and a base 3; the base 3 is provided with a top cover groove 31, the top cover 1 is disposed in the top cover groove 31, a plurality of lower pin grooves 32 are arranged in the top cover groove 31, and the top cover 1 is provided with an upper pin groove 11 corresponding to the lower pin grooves 32; one end of the conductive pin 2 passes through the lower pin groove 32 and is disposed on the base 3, and the other end of the conductive pin 2 passes through the upper pin groove 11 and is disposed on the top cover 1.

[0031] In this embodiment, the top cover 1 is installed in the top cover groove 31 provided on the base 3. Then, one end of the conductive pin 2 is placed in the lower pin groove 32 provided in the top cover groove 31, thereby fixing the conductive pin 2 in the base 3. Further, the other end of the conductive pin 2 is placed in the upper pin groove 11 provided in the top cover 1, corresponding to the conductive pin 2, thereby completing the installation of the three components. The conductive pin 2 is fixed by the upper pin groove 11 and the lower pin groove 32 to prevent the conductive pin 2 from wobbling horizontally on the top cover 1 and the base 3. The conductive pin 2 is further fixed by the top cover 1 above the conductive pin 2 to prevent the conductive pin 2 from wobbling vertically.

[0032] In this embodiment, the conductive pins 2 are arranged in a straight line. Multiple sets of linearly arranged conductive pins 2 can be set as needed, so that several conductive pins 2 are arranged in an array. The structure of the base 3 and the cover plate is then modified accordingly to install the conductive pins 2. In use, the two ends of the assembled push-button plug are grasped by both hands, moved above the array terminal block 4, and the conductive pins 2 are aligned with the wiring holes of the array terminal block 4. The plug is then pressed vertically, so that the base 3 fits against the terminal block, thereby achieving a reliable electrical connection and enabling current conduction.

[0033] In this embodiment, current can be directly conducted through the conductive pin 2. To further ensure current conduction, a conductive post 12 is provided at the top of the upper pin groove 11. The lower end of the conductive post 12 is in contact with the conductive pin 2, and the upper end of the conductive post 12 is connected to a wire. This connection between the conductive post 12 and the conductive pin 2 further enables current conduction.

[0034] In this embodiment, the conductive post 12 can be configured as a cylindrical or cuboid shape or other shape that can be connected to the wire.

[0035] Example 2:

[0036] This embodiment provides the following: Figure 1-3The diagram shows a quick-connect press-type connector, comprising a top cover 1, a plurality of conductive pins 2, and a base 3. The base 3 has a top cover groove 31, and the top cover 1 is disposed within the top cover groove 31. A plurality of lower pin grooves 32 are arranged within the top cover groove 31. The top cover 1 has upper pin grooves 11 corresponding to the lower pin grooves 32. One end of each conductive pin 2 passes through the lower pin groove 32 and is disposed on the base 3, while the other end of the conductive pin 2 passes through the upper pin groove 11 and is disposed on the top cover 1. A conductive post 12 is disposed at the top of the upper pin groove 11, the lower end of which contacts and connects to the conductive pin 2, and the upper end of which is connected to a wire.

[0037] This embodiment is based on Embodiment 1. To further increase the stability of the top cover 1 and the conductive pin 2, and to prevent poor contact between the conductive post 12 on the top cover 1 and the conductive pin 2, and to prevent the top cover 1 from falling off, a fixing component 5 is provided above the top cover 1. The lower end of the fixing component 5 is connected to the base 3. Therefore, the fixing component 5 can securely hold the top cover 1 above the conductive pin 2, ensuring stable contact between the conductive post 12 and the conductive pin 2.

[0038] The fixing component 5 in this embodiment will be described in further detail, as shown in the attached document. Figure 3 As shown, the fixing component 5 includes a first fixing part 51 and a second fixing part 52. The first fixing part 51 is horizontally disposed on the top cover 1, and both ends of the first fixing part 51 are perpendicularly connected to one end of the second fixing part 52. The other end of the second fixing part 52 is connected to the base 3. The first fixing part 51 is used to press the top cover 1 into the top cover groove 31 of the base 3, while the second fixing part 52, which is perpendicularly connected to both ends of the first fixing part 51, pulls the first fixing part 51 down through its fixed connection with the base 3, thus securing it more stably to the base 3.

[0039] In this embodiment, the fixing component 5 may use only the first fixing part 51, with through holes provided at both ends of the first fixing part 51, the middle part of the first fixing part 51 abutting against and pressing the top cover 1, and both ends of the first fixing part 51 being directly fixed to the base 3 by screws or other fasteners.

[0040] Furthermore, in the fixing component 5, two second fixing parts 52 vertically arranged at both ends of the first fixing part 51 can be pulled down, and through holes are provided on the second fixing parts 52, so that the second fixing parts 52 can be directly fixed to the base 3 by bolts or other fasteners.

[0041] To increase the ease of assembly and disassembly of the fixing component 5 and to facilitate the assembly and disassembly of the overall tooling, a fixing buckle 521 can be provided at the other end of the second fixing part 52, and a buckle groove 33 is provided on the base 3 corresponding to the position of the fixing buckle 521. This allows for direct locking via the fixing buckle 521 and the buckle groove 33, and disassembly can be performed simply by opening the buckle.

[0042] Example 3:

[0043] This embodiment provides the following: Figure 1-7 The diagram shows a quick-connect press-type connector, comprising a top cover 1, a plurality of conductive pins 2, and a base 3. The base 3 has a top cover groove 31, and the top cover 1 is disposed within the top cover groove 31. A plurality of lower pin grooves 32 are arranged within the top cover groove 31. The top cover 1 has upper pin grooves 11 corresponding to the lower pin grooves 32. One end of each conductive pin 2 passes through the lower pin groove 32 and is disposed on the base 3, while the other end of the conductive pin 2 passes through the upper pin groove 11 and is disposed on the top cover 1. A conductive post 12 is disposed at the top of the upper pin groove 11, with its lower end contacting the conductive pin 2 and its upper end connected to a wire. A fixing component 5 is disposed above the top cover 1, and the lower end of the fixing component 5 is connected to the base 3. The fixing component 5 includes a first fixing part 51 and a second fixing part 52; the first fixing part 51 is arranged laterally on the top cover 1, and both ends of the first fixing part 51 are perpendicularly connected to one end of the second fixing part 52, and the other end of the second fixing part 52 is connected to the base 3 through a fixing buckle 521.

[0044] Furthermore, in this embodiment, to ensure the accuracy and stability of the connection of the conductive pin 2, the structure of the conductive pin 2 is further improved, as shown in the attached figure. Figure 4-5 As shown, the conductive pin 2 includes a conductive protrusion 21, an insulating sleeve 22, a first metal piece 23, and a second metal piece 24. The top end of the conductive protrusion 21 is connected to the conductive post 12, and the bottom end of the conductive protrusion 21 is provided with the first metal piece 23 and the second metal piece 24. The first metal piece 23 and the second metal piece 24 are arranged in a mirror image symmetrically. The conductive protrusion 21 is used to contact the conductive post 12 on the top cover 1 to achieve electrical conductivity, while the first metal piece 23 and the second metal piece 24 are used for accurate docking with the array terminal block 4. The insulating sleeve 22 is used to further prevent electrical leakage and loss of the first metal piece 23 and the second metal piece 24 during use. Simultaneously, the shape and structure of the insulating sleeve 22 ensure that the entire conductive pin 2 can be stably engaged in the lower pin groove 32 of the base 3 and the upper pin groove 11 of the top cover 1.

[0045] The structure of the first metal sheet 23 and the second metal sheet 24 in this embodiment will be described in further detail, as shown in the attached figure. Figure 5 As shown, the tails of the first metal sheet 23 and the second metal sheet 24 bend and arch outwards, then narrow, forming an olive-shaped space 25. The middle portions of the first metal sheet 23 and the second metal sheet 24 extend close together, penetrating the insulating sleeve 22 and connecting to the conductive protrusion 21. The outward bending and arching of the tails of the first metal sheet 23 and the second metal sheet 24 allows for smooth insertion into the internal spring contacts of the terminal block. The olive-shaped space supports the spring contacts, while the close extension of the middle portions ensures the olive-shaped space and connection to the conductive protrusion 21. This arrangement ensures a stable connection between the two metal sheets and the internal spring contacts of the terminal block.

[0046] The upper pin groove 11 in this embodiment will be described in further detail, as shown in the attached figure. Figure 7 As shown, the upper pin groove 11 includes a protruding groove 111 and an insulating sleeve groove 112. The protruding groove 111 is located at one end near the conductive post 12, and the insulating sleeve groove 112 is located at the bottom of the protruding groove 111. The protruding groove 111 is used to set the conductive protrusion 21, and the insulating sleeve groove 112 is used to set the upper part of the first insulating portion 221 of the insulating sleeve 22. Similarly, the diameter of the conductive protrusion 21 is smaller than the diameter of the first insulating portion 221, which helps to stabilize the conductive pin 2.

[0047] The lower insertion pin groove 32 in this embodiment will be described in further detail, as shown in the attached figure. Figure 6 As shown, the lower insertion pin groove 32 includes a first insulating groove 321 and a second insulating groove 322. The second insulating groove 322 is disposed below the first insulating groove 321, and the diameter of the first insulating groove 321 is larger than the diameter of the second insulating groove 322. The first insulating groove 321 is used to accommodate the lower portion of the first insulating portion 221 of the insulating sleeve 22, and the second insulating groove 322 is used to accommodate the second insulating portion 222 of the insulating sleeve 22.

[0048] The insulating sleeve 22 in this embodiment will be described in further detail, as shown in the attached figure. Figure 4-5 As shown, the insulating sleeve 22 includes a first insulating part 221 and a second insulating part 222. The second insulating part 222 is disposed below the first insulating part 221, and the diameter of the first insulating part 221 is larger than the diameter of the second insulating part 222. Combined with the upper pin groove 11 and the lower pin groove 32, this ensures that a portion of the first insulating part 221 is disposed in the upper pin groove 11 of the top cover 1, while the other portion of the first insulating part 221 and the second insulating part 222 are disposed in the lower pin groove 32 of the base 3, ensuring that the entire conductive pin 2 is positioned correctly without erroneous displacement.

[0049] Detailed description of the invention:

[0050] Assembly process: First, the conductive pins 2 are placed into the lower pin grooves 32 of the base 3 in sequence. Then, the top cover 1 is spliced ​​onto the base 3. The fixing buckle 521 of the fixing component 5 above the top cover 1 needs to be locked with the buckle groove 33 of the base 3. When you hear a "click", the top of the conductive pin 2 is tightly attached to the inner wall of the conductive post 12 of the top cover 1, so as to achieve a reliable electrical connection.

[0051] Using the push-button type connector: Hold both ends of the assembled quick-connect tool (mine-clearing connector) with both hands, align the pins with the wiring holes of the connector plate 4, and press vertically to make the base 3 fit against the connector plate. At this time, the spring in the wiring hole is pushed open, and the spring's rebound force will clamp the pins, achieving a reliable electrical connection.

[0052] Current signal passes through Conductive transmission is achieved. The wires can then be plugged into the electrical control cabinet or various control systems for quick connection. To remove it, simply grasp the entire plug and pull it out vertically upwards.

[0053] Top Cover 1: The cylindrical portion at the top of the top cover 1 is a conductive post 12, which is embedded in the hole of the top cover 1. It contacts the conductive pin 2 internally and is used to connect wires externally. The pin groove is used to fix the end of the conductive pin 2, keeping it stable inside. The fixing buckles 521 on both sides of the top cover 1 are clamp-type structures, and their barbs can be locked into the buckle grooves 33 of the base 3. By pinching the short protruding side of the top of the clamp, due to the lever principle, the clamp opens slightly, allowing it to be separated from the base 3.

[0054] Conductive pin 2: Conductive pin 2 is composed of two layers of metal sheets, with its tail curved in an arc shape. The two layers of metal sheets are bent and arched outwards, forming an olive-shaped space in the middle. The cross-section of the metal sheets narrows, allowing them to be inserted into the internal spring contacts of the terminal block. The curved surface of the front metal sheet opens the spring contacts, and the spring contacts spring back under force to press the pin metal sheets together. The two layers of metal sheets are joined together in the middle, extending backwards through the insulating sleeve 22, and connecting to a cylindrical conductive protrusion 21 at the end.

[0055] Base 3: The lower pin grooves 32 of base 3 are independently insulated from each other, and the spacing between them is the same as that between the upper pin grooves 11 of top cover 1. The conductive pin 2 can be inserted into the upper pin groove 11 and the lower pin groove to achieve pin positioning and fixation. The buckle groove 33 is used to cooperate with the fixing buckle 521 on the top cover 1 to fasten and lock it in place.

[0056] The main function of this invention is to enable accurate and rapid insertion of multi-pin connectors into a terminal block. The pins can be arranged in different numbers and intervals as needed. The narrow tip and curved surface of the pins ensure a secure and effective connection to the terminal block.

[0057] In summary, after reading this invention document, those skilled in the art can make various other corresponding modifications to the technical solutions and concepts based on this invention without creative mental effort, and all of these modifications fall within the scope of protection of this invention.
