Description
Technical Field
[0001] The utility model relates to the technical field of electrical appliances, in particular to a side-inlet terminal with a grounding function. Background Art
[0002] A wiring terminal is a fitting product specifically used to achieve electrical connection and is classified as a type of connector in the industrial field. With the continuous improvement of industrial automation levels and the increasingly strict and precise industrial control requirements, the usage amount of wiring terminals shows a gradually increasing trend. With the booming development of the electronics industry, the application scope of wiring terminals has become more and more extensive, and the types have also become increasingly diverse. Among many wiring terminals, in addition to PCB board terminals widely used on printed circuit boards (PCBs), there are also various types such as hardware terminals, nut terminals, and spring terminals, which are very common in practical applications. However, when the existing wiring terminals realize the plug-in connection of two wires, the commonly used method is to squeeze the wire through a screw so that the plug can be pressed tightly on the metal conductor inside the wiring terminal. Although this method can achieve reliable electrical connection, it is relatively cumbersome and inconvenient during the installation and disassembly processes. During installation, it is necessary to carefully adjust the screw to ensure that there is sufficient pressure between the wire and the metal conductor to ensure the stability of the connection; during disassembly, it is necessary to loosen the screws one by one, and the operation process is both time-consuming and laborious. Therefore, although wiring terminals play an important role in electrical connection, the convenience of their installation and disassembly still needs to be further improved and optimized.
[0003] In the patent "Wiring Terminal" (publication number CN214673032U, hereinafter referred to as the prior art 1), it is disclosed that the main technical principle in the prior art 1 is to form a clamping part by the end of the conductive element abutting against the end of the elastic element to clamp and fix the wire, and to drive the elastic element by pressing the pressing element to control the clamping part to clamp or loosen the wire, so as to achieve more convenient and fast wiring.
[0004] In the existing technology 1, the design of the terminal makes wiring convenient and fast. However, these wiring terminals are not equipped with a special grounding component. This lack of design may pose a safety hazard when the equipment fails. Specifically, when the equipment fails, the current may leak through the ungrounded terminal, thus causing electric shock to the operator. In this case, the operator may face the risk of electric shock because there is no effective grounding measure to ensure that the current can be safely introduced into the ground to avoid harm to personnel. Therefore, although the terminals in the prior art 1 have certain convenience in wiring, there are obvious deficiencies in terms of safety and need to be further improved to ensure the safety of the operator.

[0039] Embodiment 1
[0040] Please refer to Figure 1 , the embodiments of the present utility model provide a grounded side-inlet terminal, which is specially equipped with components dedicated to grounding. This design enables the current generated by leakage to quickly pass through these grounding components when a leakage occurs in the circuit, effectively guiding the current into the ground, thereby preventing the current from passing through the human body. In this way, when operating personnel are installing, maintaining, or overhauling electrical equipment, they can obtain more secure protection, greatly reducing the risk of electric shock and ensuring the life safety of the operating personnel. And the static electricity generated between the circuit or the conductive sheet 400 can also be introduced into the ground, extending the service life of electrical components.
[0041] Please refer to Figure 1 , a grounded side-inlet terminal, includes an insulating housing 100 and a plurality of key components, including a push block component 200, a grounding card plate 300, a conductive sheet 400, and a spring sheet 500. These components are arranged inside the insulating housing 100 to ensure the normal operation and safe use of the entire device.
[0042] Specifically, please refer to Figure 2 , the insulating housing 100 is the basic structure of the entire incoming line terminal. It not only provides an installation space for each component but also ensures the insulation performance of the entire device. The insulating housing 100 is made of insulating material, which can effectively prevent current leakage and thus avoid electric shock accidents. In addition, the design of the insulating housing 100 also takes into account heat dissipation and mechanical strength to ensure stable operation in various environments.
[0043] Please refer to Figure 3 , the push block assembly 200 is one of the core parts of the incoming line terminal. The push block assembly 200 is mainly responsible for determining whether the wire 600 at both ends of the insulating housing 100 is successfully connected after the wire 600 is inserted into the insulating housing 100.
[0044] Please refer to Figure 8 , the grounding card plate 300 is a key component responsible for safety in the incoming line terminal. Its main function is to conduct unsafe current into the ground to protect the safety of equipment and personnel. The design of the grounding card plate 300 complies with relevant safety standards to ensure its grounding function even under high current conditions. The conductive sheet 400 is the core component responsible for current transmission in the incoming line terminal. It closely cooperates with the elastic sheet 500 to ensure good electrical connection between the wire 600 and the conductive sheet 400. The conductive sheet 400 is usually made of high-conductivity material to reduce resistance and heat generation and improve the overall transmission efficiency.
[0045] Please refer to Figure 7 , the elastic sheet 500 is the component responsible for maintaining contact pressure in the incoming line terminal. It can ensure that a stable contact pressure is always maintained between the conductive sheet 400 and the wire 600, thus avoiding problems such as increased resistance and heat generation caused by poor contact; and it can reach the push block assembly 200 after the wire 600 is inserted. The elastic sheet 500 has sufficient elasticity and durability to adapt to wires 600 of different thicknesses and hardnesses; it can also maintain the rebound performance under long-term operation.
[0046] Please refer to Figure 5, on both sides of the insulating housing 100, a first wiring port 110 and a second wiring port 120 are respectively provided. These wiring ports are designed to conveniently guide the wire 600 into the internal space of the insulating housing 100. Specifically, the wire 600 can enter through the first wiring port 110, and another wire 600 enters through the second wiring port 120, thus ensuring the orderly layout and safe connection of the wire 600. In addition, in order to further enhance the installation and fixing functions of the insulating housing 100, mounting slots 130 are provided at its bottom. These slots not only provide additional mechanical strength but also allow the grounding card plate 300 to be installed inside the insulating housing 100 through these slots. The function of the grounding card plate 300 is to ensure the grounding safety of the entire device, prevent current leakage or accidental electric shock, thereby improving the overall electrical safety performance. Through this design, the combination of the insulating housing 100 and the grounding card plate 300 not only achieves the stability and reliability of electrical connection but also ensures the safe operation of the device in various working environments.
[0047] Please refer to Figure 2 and Figure 7 , the elastic piece 500 is arranged inside the insulating housing 100 through the first positioning post 140 and the second positioning post 150. During the installation process, the elastic piece 500 needs to be maintained in a very accurate position so that it can accurately trigger the push block assembly 200 after being triggered by the wire 600. This precise positioning process is crucial for observing whether the wiring is successful. Through the precise cooperation of the first positioning post 140 and the second positioning post 150, the position of the elastic piece 500 can be determined, thus ensuring that the elastic piece 500 can be correctly installed in the predetermined position. This installation method improves the reliability of the wiring.
[0048] Please refer to Figure 6 , the conductive sheet 400 is made of a metal sheet through the processes of bending and folding. The design feature of this metal sheet is that its two sides are convex, while the middle part is concave. At both ends of the conductive sheet 400, a push block assembly 200 and an elastic piece 500 are respectively installed. These two components are placed at both ends of the conductive sheet 400 to ensure that after the wire 600 is connected, the conductive sheet 400 can be in close contact with the elastic piece 500. In this way, when current passes through the conductive sheet 400, the conduction operation of the current can be smoothly carried out to ensure the normal operation of the circuit.
[0049] Within the recessed area of the conductive sheet 400, there are two outer surfaces, namely the first conductive surface 410 and the second conductive surface 420. When the wire 600 is connected and incorporated into this system, the wire 600 will come into contact with the elastic sheet 500. As the wire 600 is connected, it exerts a force on the elastic sheet 500, pushing the elastic sheet 500 to move inward. This movement enables the wire 600 to make close contact with the two conductive surfaces of the conductive sheet 400 (i.e., the first conductive surface 410 and the second conductive surface 420) through the elastic sheet 500. Through this contact, the current can flow smoothly, thereby achieving the conduction state of the circuit. This design ensures that the current can flow stably through the conductive sheet 400, and at the same time provides a good contact effect, ensuring the reliability and stability of the circuit.
[0050] Please refer to Figure 7 , at one end of the elastic sheet 500 close to the first conductive surface 410 or the second conductive surface 420, a trigger baffle 550 is specifically provided. The function of this trigger baffle 550 is to, when it is necessary to connect the wire 600 to the conductive sheet 400, by pushing the trigger baffle 550 on the elastic sheet 500, using it as a medium, thus realizing the connection between the wire 600 and the conductive sheet 400.
[0051] Please refer to Figure 6 , a bayonet 430 is provided at the recess of the conductive sheet 400. The buckle is used to snap and connect the grounding card board 300, so that a fixed connection is made between the grounding card board 300 and the conductive sheet 400 and the circuit is conducted.
[0052] Please refer to Figure 8 , the two sides of the grounding card board 300 are respectively provided with a first grounding leg 310 and a second grounding leg 320. The two sides of the grounding card board 300 respectively introduce the unsafe current into the ground through the first grounding leg 310 and the second grounding leg 320. A raised first clamping boss 330 and a second clamping boss 340 are provided in the middle part of the grounding card board 300. The grounding card board 300 is arranged in the buckle through the first clamping boss 330 and the second clamping boss 340, and the grounding card board 300 is fixed on the conductive sheet 400.
[0053] The first clamping protrusion 330 is provided with a bend; the first clamping protrusion 330 clamps the grounding clamping plate 300 with the clamping opening 430 on the conductive sheet 400 through the installation slot 130 at the bend. Generally, the distance between the first clamping protrusion 330 and the second clamping protrusion 340 should be greater than the width of the clamping opening 430, so that the clamping opening 430 can clamp the first clamping protrusion 330 and the second clamping protrusion 340, but if the distance between the first clamping protrusion 330 and the second clamping protrusion 340 is too large, the first clamping protrusion 330 cannot enter the clamping opening 430. Therefore, the bending part is provided, and a gap is provided between the first clamping boss 330 and the second clamping boss 340, so that the first clamping boss 330 and the second clamping boss 340 are brought close together through the bending part, and the width of the first clamping boss 330 and the second clamping boss 340 when they are brought close together is smaller than the width of the buckle, and when the first clamping boss 330 and the second clamping boss 340 enter the bayonet 430, since the width of the bending part is smaller than the width of the bayonet 430, the bending part is clamped through the bayonet 430. In addition, there is also an opening force at the bending part, so that the first clamping boss 330 and the second clamping boss 340 are in contact with the conductive sheet 400.
[0054] See also Figure 2 The push block assembly 200 includes a push block 210, a spring 220 and a top block 230; the push block 210 and the top block 230 are fixed by clamping. The push block 210 and the top block 230 are provided with protrusions and recesses for matching, and the installation of the push block 210 and the top block 230 is guided by the protrusions and recesses, so as to ensure the uniqueness of the installation of the push block 210 and the top block 230.
[0055] See also Figure 9 The push block 210 has a cavity inside; the top block 230 is formed by bending a metal plate and is provided with a through-hole inside, and an opening is provided on the top of the top block 230. The push block 210 and the top block 230 are provided with an internal cavity type, mainly to facilitate the installation of the spring 220, and to facilitate the compression and release of the spring 220 after installation.
[0056] See also Figure 9 , the spring 220 is arranged inside the push block 210 and the top block 230; one end of the conductive sheet 400 is arranged inside the top block 230; the two ends of the spring 220 are respectively in contact with the top of the cavity of the push block 210 and the top of one end of the conductive sheet 400. The spring 220 is arranged inside the push block assembly 200, and is covered by the top block 230 and the push block 210, and the two ends are fixed by the push block 210 and the conductive sheet 400. When the push block assembly 200 is pressed downward, the spring 220 is compressed and gathered in the position between the conductive sheet 400 and the push block assembly 200.
[0057] See also Figure 5, on both sides of the top of the insulating housing 100, a first observation groove 160 and a second observation groove 170 are respectively provided; push block assemblies 200 are provided in both the first observation groove 160 and the second observation groove 170. The push block assemblies 200 are arranged and installed through the first observation groove 160 and the second observation groove 170. The positions of the push block assemblies 200 in the grooves can also be observed through the first observation groove 160 and the second observation groove 170. When the top of the push block assembly 200 is flush with the tops of the first observation groove 160 and the second observation groove 170, it means that the wiring is successful.
[0058] Please refer to Figure 2 and Figure 3 , on one side of the push block 210, a guiding groove 211 is provided; guiding protrusions 171 are provided inside the first observation groove 160 and the second observation groove 170; the push block 210 is engaged with the guiding protrusions 171 of the first observation groove 160 or the second observation groove 170 through the guiding groove 211. When the push block assemblies 200 are arranged in the first observation groove 160 and the second observation groove 170, without the guiding protrusions 171, the positions of the push block assemblies 200 cannot be determined and they cannot move along the preset trajectory when the push block assemblies 200 are displaced. Therefore, the guiding protrusions 171 are provided. The installation and displacement paths of the push block assemblies 200 are planned. Further, first ribs and second ribs are respectively provided at the lower ends of the two observation grooves of the insulating housing 100; the first rib and the second rib interact to form a sliding track for the up-and-down movement of the top block 230, preventing the push block assemblies 200 from swinging left and right and outwards. The first positioning post 140 and the second positioning post 150 are used for installing and fixing the elastic sheet 500. At the same time, the second positioning post 150 can also prevent the hook of the elastic sheet 500 from deforming upwards when stressed.
[0059] Preferably, the elastic sheet 500 is formed by bending a metal plate inwards. The two bent portions of the elastic sheet 500 are respectively a first installation portion 510 and a second installation portion 520. The first installation portion 510 and the second installation portion 520 are respectively fitted and positioned with the first positioning post 140 and the second positioning post 150. The two ends of the elastic sheet 500 are respectively a wire clamping port 540 and a trigger baffle 550. After the wire 600 is inserted into the first wiring port 110 or the second wiring port 120, it passes through the cavity inside the top block 230 and contacts the trigger baffle 550. This contact causes the trigger baffle 550 to be pushed inwards until it is in close contact with the conductive sheet 400. During this process, the connection between the elastic sheet 500 and the top block 230 is automatically disengaged, thus achieving the purpose of wiring. Since the elastic sheet 500 itself has a certain resilience, the wire clamping port 540 uses this resilience to firmly hold the wire 600, thereby fixing the position of the wire 600. In this way, the wire 600 will not fall out of the first wiring port 110 or the second wiring port 120.
[0060] Please refer to Figure 7 , on both sides of the trigger baffle 550 are respectively a first hook 560 and a second hook 570. On both sides of the bottom of the top block 230 are respectively provided with a first hook groove 231 and a second hook groove 232; the first hook 560 and the second hook 570 are respectively arranged in the first hook groove 231 and the second hook groove 232, and limit the position of the push block assembly 200. In the present utility model, on both sides of the trigger baffle 550 are respectively equipped with the first hook 560 and the second hook 570. The function of these hooks is to ensure that the trigger baffle 550 can be stably fixed in place. Specifically, on both sides of the bottom of the top block 230 are respectively designed with the first hook groove 231 and the second hook groove 232. The setting of these two hook grooves is to cooperate with the first hook 560 and the second hook 570, so as to realize the precise position limitation of the push block assembly 200. Through this design, the first hook 560 and the second hook 570 are respectively embedded into the first hook groove 231 and the second hook groove 232, so that the push block assembly 200 will not shift in position during use, thus ensuring the stability and reliability of the entire device.
[0061] Preferably, the second mounting portion 520 is further provided with a limit baffle 530; an opening is provided on the limit baffle 530. On both sides of both ends of the conductive sheet 400 are provided with "U"-shaped notches 440; the top block 230 is arranged between the "U"-shaped notches 440 on both sides of the conductive sheet 400. On the outer sides of both sides of the bottom of the conductive sheet 400 are provided with limit support strips 450; the limit support strips 450 are arranged in the openings on the limit baffle 530. Convex protrusions 441 are provided in the "U"-shaped notches 440 of the conductive sheet 400; on both sides of the top block 230 are provided with guiding long holes 233; the convex protrusions 441 are arranged in the guiding long holes 233. On the left and right ends of the conductive sheet 400, two groups of "U"-shaped notches 440 are symmetrically arranged front and back respectively. The distance between the bottoms of each group of "U"-shaped notches 440 is less than the distance between the two straight edges of the top block 230. In the middle of the bottom of each group of "U"-shaped notches 440, a group of convex protrusions 441 are symmetrically arranged. On both sides of the bottom of the conductive sheet 400, two support strips are respectively arranged, and the two support strips are warped upwards; the top block 230 is clamped between the "U"-shaped notches 440. Through the cooperation of the convex protrusions 441 at the bottom of the "U"-shaped notches 440 and the two rectangular holes on the side of the top block 230, it is ensured that the push block assembly 200 does not come out of the insulating housing 100, but realizes a regular stroke function.
[0062] Preferably, through holes are provided on the surface of the insulating housing 100. The function of the through holes is to effectively connect the external environment with the internal grounding plate 300, thereby achieving the grounding function. In addition, the through holes are not just a simple connection channel, but also have a dual function. First, it serves as the installation hole for the grounding plate 300, enabling the grounding plate 300 to be smoothly installed on the insulating housing 100. Second, the through holes also play a role in restricting the displacement of the grounding plate 300, ensuring that the grounding plate 300 remains stable during use and does not move unnecessarily, thereby guaranteeing the reliability and safety of the entire grounding system.
[0063] Please refer to Figure 1 and Figure 4 , when the incoming line terminal is in the original state, the conductive sheet 400 and the elastic sheet 500 are first installed inside the insulating housing 100. A push block assembly 200 is respectively arranged in the first observation groove 160 and the second observation groove 170, so that the push block assembly 200 presses down the elastic sheet 500 and compresses the spring 220; the first hook groove 231 and the second hook groove 232 of its top block 230 are respectively connected to the first hook 560 and the second hook 570, fixing the position of the push block assembly 200. During use, the wire 600 is respectively connected into the insulating housing 100 through the first wiring port 110 and the second wiring port 120, passes through the cavity of the top block 230 and contacts the trigger baffle 550, pushing the trigger baffle 550 to contact the conductive sheet 400. The elastic sheet 500 rebounds and the spring 220 releases, pushing the push block assembly 200 upward to move it to the top of the insulating housing 100 and be flush with the top of the insulating housing 100, which means the wiring is completed. When installing the grounding product, the grounding plate 300 is inserted from the installation long hole 130 at the lower end of the insulating housing 100, so that the boss of the grounding plate 300 is stuck into the bayonet 430 of the conductive sheet 400, completing the assembly work of the grounding product.
