[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1 to 7As shown, this utility model proposes a press-fit junction box, including a housing. The housing includes a lower cover and an upper cover 2. The lower cover includes at least one wiring station 1, which is snapped into the upper cover 2. The wiring station 1 is used to place the terminal wire to be wired. At least one spring 24 is installed inside the upper cover 2. The spring 24 is used to pierce the wire insulation and core of the terminal wire to achieve the function of conducting electricity. In use, the terminal wire to be wired is placed in the wiring station 1 of the lower cover, and then the upper and lower covers and the upper cover 2 are connected and snapped in place. When the upper cover 2 is combined with the lower cover, the spring 24 will correspondingly pierce the wire insulation to reach the core, thereby completing the electrical connection without the need for professional tools in traditional wiring methods. The entire process relies on the pressing action of the mechanical structure to achieve electrical connection, simplifying the wiring process. This design greatly improves wiring efficiency, reduces the skill requirements of the operator, and allows personnel without professional knowledge to easily complete wiring tasks. At the same time, by eliminating the traditional steps of stripping wires and tightening screws, not only is the required time reduced, but safety hazards or wiring errors caused by improper use of tools are also avoided, thus improving the safety and reliability of the work.

[0031] Furthermore, as a preferred embodiment of this utility model and not a limitation, the wiring station 1 is provided with a side wall portion 12, the side wall portion 12 is provided with a first mating portion 13, and the upper cover 2 is provided with a first connecting portion 22 that engages with the first mating portion 13. This structural optimization makes the assembly process simpler and faster, allowing even untrained personnel to easily assemble the junction box. The engaging mechanism between the first mating portion 13 and the first connecting portion 22 not only simplifies the fixing process of the upper and lower covers but also ensures the stability of the junction box during use, effectively preventing accidental opening or damage due to vibration or other external forces, and enhancing the practicality and reliability of the press-connect junction box.

[0032] Optionally, in some embodiments, the first mating part 13 is a locking block, and the first connecting part 22 is a locking groove, with the first connecting part 22 engaging with the locking block. This locking block and locking groove design achieves a stable connection between the wiring station 1 and the upper cover 2 through mechanical locking, ensuring that the junction box remains tightly fitted when closed.

[0033] Optionally, in some embodiments, the locking block is provided with an inclined portion. The inclined portion design reduces the initial contact resistance between the locking block and the slot, making the closing operation of the upper and lower covers smoother.

[0034] Furthermore, as a preferred embodiment of this utility model and not a limitation, a PCB board 23 is installed inside the upper cover 2. The PCB board 23 has a groove 231, and the spring contact 24 is installed in the groove 231. This design, through the positioning and support of the groove 231, ensures the stability and accuracy of the spring contact 24, enabling it to accurately pierce the wire insulation of the terminal wire and make contact with the wire core during pressing, thereby achieving a reliable electrical connection. The introduction of the groove 231 simplifies the assembly process of the spring contact 24, reduces the assembly difficulty and cost in the production process, and also facilitates later maintenance and upgrades.

[0035] Furthermore, as a preferred embodiment of this utility model and not a limitation thereof, the spring 24 is provided with a second connecting portion 241, and the PCB board 23 is provided with a second mating portion 232 that engages with the second connecting portion 241. This design not only ensures the precise positioning of the spring 24 on the PCB board 23, but also enhances the stability of the spring 24, preventing displacement or loosening during pressing or use. Through the snap-fit ​​structure of the second connecting portion 241 and the second mating portion 232, the spring 24 can be firmly installed in the slot 231, thereby ensuring the accuracy of its force and position when piercing the terminal wire insulation, further improving the reliability of the electrical connection. The snap-fit ​​structure simplifies the assembly process of the spring 24, allowing installation to be completed without additional welding or complex tools, significantly improving production efficiency and reducing manufacturing costs.

[0036] Optionally, in some embodiments, the second connecting part 241 is a locking block, and the second mating part 232 is a locking groove.

[0037] Optionally, in some embodiments, the second connecting part 241 is a slot and the second mating part 232 is a locking block.

[0038] Furthermore, as a preferred embodiment of this utility model and not a limitation, the spring 24 is provided with at least one insertion portion 242, one end of which is a sharp angle. The insertion portion 242 is used to pierce the wire sheath of the terminal wire and make contact with the wire core. The purpose of this design is to effectively pierce the wire sheath of the terminal wire using the sharp angle end of the insertion portion 242, and directly contact the internal wire core, thereby achieving the function of electrical connection. The sharp angle design of the insertion portion 242 ensures sufficient penetration force, enabling accurate penetration of the wire sheath under relatively low pressure, while avoiding damage to the wire core, ensuring the safety and reliability of the electrical connection. By providing multiple insertion portions 242, the number of contact points with the wire core can be increased, which not only improves the stability and efficiency of current transmission, but also disperses pressure to a certain extent, reducing the risk of damage caused by single-point stress concentration.

[0039] Furthermore, as a preferred embodiment of this utility model and not a limitation, the lower cover is provided with a lower wire groove 11, which is used to limit the terminal wire. The upper cover 2 has an upper wire groove 21 that matches the lower wire groove 11, which is also used to limit the terminal wire. When the lower cover is provided with a lower wire groove 11 specifically for limiting the terminal wire, the terminal wire can be accurately placed in a predetermined position, ensuring that the direction and position of each cable are correct. Then, when the upper cover 2 and the lower cover are closed, the upper wire groove 21 on the upper cover 2 is precisely aligned with the lower wire groove 11 and works together to firmly limit the connected terminal wire from both the top and bottom, preventing problems such as wire crossing or misalignment during the closing of the upper and lower covers or puncturing the connection.

[0040] Furthermore, as a preferred embodiment of this utility model and not a limitation, the PCB board 23 has a slot 233, and the upper cover 2 is provided with a plug that matches the shape of the slot 233. Through the precise fit between the plug and the slot 233, a stable connection between the PCB board 23 and the upper cover 2 is achieved. During assembly, the plug is accurately inserted into the slot 233, ensuring the precise positioning of the PCB board 23 inside the junction box and avoiding functional failure or performance degradation due to positional deviation. This structure not only enhances the mechanical stability of the overall device but also provides additional protection for electrical components, preventing damage caused by vibration or other physical interference. In addition, the design of the plug and slot 233 simplifies the assembly process and improves production efficiency.

[0041] Furthermore, as a preferred embodiment of this utility model and not a limitation, the upper cover 2 has a groove 25 for accommodating the side wall portion 12 of the wiring station 1. When the upper and lower covers are closed, the side wall portion 12 can be perfectly embedded in the groove 25, thereby achieving a more stable and tighter assembly effect. In addition, this matching design of the groove 25 and the side wall portion 12 simplifies the assembly process, making it easier for the upper and lower covers to be aligned and closed, reducing the possibility of misoperation. At the same time, this design also optimizes the utilization efficiency of the internal space, making the entire device more compact.

Meanwhile, by eliminating the traditional steps of stripping wires and tightening screws, not only is the required time reduced, but safety hazards or wiring errors caused by improper tool use are also avoided, thus improving the safety and reliability of the work. The spring contact 24 is provided with at least one insertion part 242, one end of which is a sharp angle. The insertion part 242 is used to pierce the wire insulation of the terminal wire and make contact with the wire core. The purpose of this design is to effectively pierce the wire insulation of the terminal wire using the sharp end of the insertion part 242, directly contacting the internal wire core, thereby achieving the function of electrical connection. The sharp angle design of the insertion part 242 ensures sufficient penetration force, accurately penetrating the wire insulation under relatively low pressure, while avoiding damage to the wire core, ensuring the safety and reliability of the electrical connection. By providing multiple insertion parts 242, the number of contact points with the wire core can be increased, which not only improves the stability and efficiency of current transmission, but also disperses pressure to a certain extent, reducing the risk of damage caused by single-point stress concentration.

[0044] The wiring station 1 is equipped with a side wall portion 12, and the side wall portion 12 is equipped with a first mating portion 13. The upper cover 2 is equipped with a first connecting portion 22 that engages with the first mating portion 13. This structural optimization makes the assembly process simpler and faster, allowing even untrained personnel to easily assemble the junction box. The engagement mechanism between the first mating portion 13 and the first connecting portion 22 not only simplifies the fixing process of the upper and lower covers but also ensures the stability of the junction box during use, effectively preventing accidental opening or damage due to vibration or other external forces, and enhancing the practicality and reliability of the press-connected junction box. The first mating portion 13 is a locking block, and the first connecting portion 22 is a locking groove, with the first connecting portion 22 engaging with the locking block. This locking block and groove design achieves a stable connection between the wiring station 1 and the upper cover 2 through mechanical locking, ensuring that the junction box remains tightly fitted when closed. The locking block is equipped with an inclined portion. The inclined portion design reduces the initial contact resistance between the locking block and the locking groove, making the closing operation of the upper and lower covers smoother.

[0045] A PCB board 23 is installed inside the upper cover 2. The PCB board 23 has a groove 231, and the spring contact 24 is installed in the groove 231. This design, through the positioning and support of the groove 231, ensures the stability and accuracy of the spring contact 24, enabling it to accurately pierce the wire insulation and make contact with the wire core during pressing, thereby achieving a reliable electrical connection. The introduction of the groove 231 simplifies the assembly process of the spring contact 24, reduces the assembly difficulty and cost in the production process, and also facilitates later maintenance and upgrades.

[0046] The spring contact 24 is provided with a second connecting part 241, and the PCB board 23 is provided with a second mating part 232 that engages with the second connecting part 241. The second connecting part 241 is a locking block, and the second mating part 232 is a locking groove. This design not only ensures the precise positioning of the spring contact 24 on the PCB board 23, but also enhances the stability of the spring contact 24, preventing displacement or loosening during pressing or use.

The locking structure simplifies the assembly process of the spring contact 24, allowing installation to be completed without additional soldering or complex tools, significantly improving production efficiency and reducing manufacturing costs.

[0047] The lower cover has a lower wire groove 11 for limiting the terminal wire. The upper cover 2 has an upper wire groove 21 that matches the lower wire groove 11, and the upper wire groove 21 is also used to limit the terminal wire. When the lower cover has a lower wire groove 11 specifically for limiting the terminal wire, the terminal wire can be accurately placed in the predetermined position, ensuring that the direction and position of each cable are correct. Then, when the upper cover 2 and the lower cover are closed, the upper wire groove 21 on the upper cover 2 is precisely aligned with the lower wire groove 11 and works together to firmly limit the connected terminal wire from both the top and bottom, preventing problems such as wire crossing or misalignment during the closing of the upper and lower covers or puncturing the connection.

[0048] The PCB board 23 has slots 233, and the upper cover 2 has inserts that match the shape of the slots 233. Through the precise fit between the inserts and slots 233, a stable connection is achieved between the PCB board 23 and the upper cover 2. During assembly, the inserts accurately insert into the slots 233, ensuring precise positioning of the PCB board 23 inside the junction box and preventing functional failure or performance degradation due to positional deviations. This structure not only enhances the mechanical stability of the overall device but also provides additional protection for electrical components, preventing damage caused by vibration or other physical interference. Furthermore, the design of the inserts and slots 233 simplifies the assembly process and improves production efficiency. The upper cover 2 has a recess 25 to accommodate the side wall portion 12 of the wiring station 1.

[0049] Specifically, the working principle of this utility model is as follows:

[0050] In use, the terminal wire is placed in the wiring station 1 of the lower cover. The wiring station 1 is provided with a lower wire groove 11 for fixing and limiting the position of the terminal wire. Subsequently, the upper and lower covers are joined together and securely closed by the snap-fit ​​mechanism between the first mating part 13 and the first connecting part 22. A PCB board 23 is installed inside the upper cover 2, on which a spring piece 24 is provided. When the upper and lower covers are closed, the insertion part 242 on the spring piece 24 uses a sharp angle design to pierce the wire insulation of the terminal wire and reach the wire core, completing the electrical connection process.

[0051] During assembly, the PCB board 23 precisely engages with the slot 233 inside the upper cover 2 via the insert block, ensuring the accurate positioning and stability of the PCB board 23. Simultaneously, the spring 24 engages with the second mating part 232 on the PCB board 23 via the second connecting part 241, further enhancing the stability of the spring 24 and ensuring that it accurately pierces the terminal wire insulation and contacts the wire core during pressing. This design not only guarantees the reliability of the electrical connection but also simplifies the assembly process, making the entire device more compact and efficient.

[0052] The upper cover 2 has a groove 25 to accommodate the side wall portion 12 of the wiring station 1. When the upper and lower covers are closed, the side wall portion 12 is embedded in the groove 25, ensuring a tight fit between the upper and lower covers. Furthermore, this groove-side wall design simplifies the assembly process, making it easier to align and close the upper and lower covers, reducing the possibility of misoperation. Simultaneously, this design optimizes the utilization efficiency of internal space, making the entire device more compact. The combined use of the upper and lower wire slots (upper slot 21 and lower slot 11) securely limits the accessed terminal wires from both upper and lower directions, preventing wire crossing or misalignment during the closing of the upper and lower covers or puncturing the connection.

[0053] In summary, this utility model solves the problems of complex wiring, the need for professional tools, and low wiring efficiency of traditional junction boxes.
