Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, specifically to a measurement switch that is easy to wire. It can be widely used in power systems, industrial control equipment, and civil electrical equipment to realize circuit on / off control and electrical parameter measurement functions, while simplifying the wiring operation process. Background Technology

[0002] As an electrical component that combines circuit control and parameter monitoring functions, measuring switches are widely used in various power consumption scenarios.

[0003] However, existing measurement switches present numerous problems during wiring. First, most traditional measurement switches employ a screw-fastening wiring structure, requiring the use of a screwdriver to secure each wire individually. This cumbersome process, especially in multi-circuit wiring scenarios, is time-consuming and significantly impacts installation efficiency. Furthermore, installers often lack an effective initial positioning structure for the wiring, requiring them to hold the wire with one hand while operating the screwdriver with the other, increasing the difficulty and the risk of wire misalignment, further complicating the wiring process. Second, improper torque control in screw-fastening methods can easily lead to loose wires and poor contact, affecting both measurement accuracy and circuit safety.

[0004] Therefore, it is necessary to design a measurement switch that is easy to wire to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of existing measuring switches, such as difficulty in wiring positioning and cumbersome installation operations, and to provide a measuring switch that is easy to wire. By adding an elastic clamping component, the initial positioning of the circuit is achieved, and the wiring convenience and stability are improved in combination with the existing screw fastening structure.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A measuring switch for easy wiring includes a switch body with wiring grooves on its upper and lower sides. These grooves accommodate wires to be connected, ensuring the wires remain neatly arranged during wiring. A terminal block is fixedly installed inside each wiring groove, with a through-hole that mates with a terminal at the end of the wire, allowing for a secure connection between the wire and the terminal block via screw tightening.

[0007] Furthermore, an elastic clamping assembly is provided on one side of the terminal block corresponding to the wiring hole position. The elastic clamping assembly includes a fixed sleeve, a torsion spring, an elastic connecting piece, and an arc-shaped clamping sleeve. The fixed sleeve is detachably installed on the side of the terminal block by screws, providing a mounting base for the entire assembly. One end of the torsion spring is fixed inside the lower part of the fixed sleeve, and the other end is connected to one side of the elastic connecting piece, providing a continuous clamping force through the elastic deformation of the torsion spring. The other side of the elastic connecting piece is fixedly connected to the outer wall of the arc-shaped clamping sleeve. The arc-shaped clamping sleeve has a semi-enclosed structure, and its curvature is adapted to the outer contour of common circuits, used for preliminary clamping and positioning of the circuit before it is inserted into the wiring hole.

[0008] Furthermore, the inner wall of the arc-shaped clamping sleeve is lined with a soft pad made of insulating elastic material. This pad increases the friction between the clamping sleeve and the wire to enhance the positioning effect, while also preventing damage to the outer insulation layer of the wire during clamping. The arc-shaped clamping sleeve is made of copper alloy, which combines good structural strength and elastic recovery, adapting to the clamping needs of wires of different diameters and maintaining stable clamping performance even after long-term use.

[0009] Furthermore, a sealing cover is fitted onto the outside of the wiring trough. The sealing cover is made of insulating material and is detachably connected to the wiring trough via a snap-fit ​​structure. This provides protection for the internal wiring structure and facilitates later maintenance and repair. The inner wall of the wiring trough is coated with an insulating coating, further enhancing the overall insulation performance of the switch and preventing leakage between the wiring and the switch body.

[0010] Furthermore, a conductive plate is fixedly installed on the terminal block. One end of the conductive plate is connected to the inside of the wiring hole, and the other end extends into the switch body and is electrically connected to the measuring circuit, ensuring that after the line is connected, electrical parameters such as voltage and current can be monitored through the measuring circuit. A control switch is provided on the front of the switch body, which can be used to switch the circuit on / off state.

[0011] This utility model, through the coordinated design of the elastic clamping component and the screw fastening structure, first uses the elastic clamping component to initially position and fix the circuit, freeing the installer's hands from operation, and then uses screws to fasten the wiring terminals to the wiring holes. This simplifies the wiring process and ensures the stability of the circuit connection, effectively solving the problems of difficult positioning and cumbersome operation when wiring traditional measuring switches.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This utility model, by providing a convenient wiring measurement switch, achieves the following effects: 1. By incorporating an elastic clamping component, the inserted wire can be initially positioned. Installers no longer need to hold the wire with one hand and operate other components with the other, simplifying the operation, reducing wiring difficulty, minimizing installation hassle, and improving wiring convenience. 2. The elastic clamping component initially positions the wire, which is then further secured by screws. This combination effectively avoids difficulties in screw tightening or loosening of the wire after fixation due to wire misalignment, ensuring more stable and reliable wire fixation and guaranteeing measurement accuracy and circuit safety. 3. The elastic clamping component can adapt to wires of different diameters within a certain range, exhibiting good versatility. This reduces the need for additional matching accessories due to wire diameter mismatch during installation, facilitating installation. 4. Because the elastic clamping component achieves initial wire positioning, it simplifies wiring operations, making the wiring process smoother for installers. Compared to traditional measurement switches without an initial positioning structure, wiring efficiency is significantly improved, helping to shorten overall installation time.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete. Example

[0017] Please see Figure 1 This embodiment provides a measurement switch that is easy to wire, which is mainly used for circuit on / off control and electrical parameter measurement in industrial control equipment; The measuring switch includes a switch body 1, which is made of flame-retardant ABS material, possessing excellent high-temperature resistance and insulation properties, and can adapt to complex environments in industrial settings. Two wiring slots 2 are symmetrically provided above and below the switch body 1 for placing the wiring 21. The width of the slot opening 2 is adapted to the outer diameter of common industrial control wiring 21, ensuring that the wiring 21 does not easily wobble after placement. Simultaneously, the inner wall of the wiring slot 2 is uniformly coated with an insulating coating made of epoxy resin, which has uniform thickness and strong adhesion, effectively preventing leakage between the wiring 21 and the switch body 1, ensuring industrial electrical safety. Example

[0018] Please see Figure 2 , Figure 3 , Figure 4 as well as Figure 5Based on Embodiment 1, this embodiment further specifies that each wiring slot 2 is fixedly equipped with a terminal block 3. The terminal block 3 is made of copper and has excellent conductivity. A wiring hole 4 is opened through the terminal block 3. The diameter of the wiring hole 4 matches the outer diameter of the terminal 22 at the bottom of the line 21. The terminal 22 can be inserted into the wiring hole 4 and fastened to the terminal block 3 by screws to achieve stable fixation of the line 21 and the terminal block 3. On one side of the terminal block 3, a set of elastic clamping components 5 for clamping the line 21 is fixedly installed at the position corresponding to the wiring hole 4. The elastic clamping components 5 include a fixing sleeve 51, a torsion spring 52, an elastic connecting piece 53, and an arc-shaped clamping sleeve 54. The fixing sleeve 51 is made of stainless steel and is detachably fixed to the side of the terminal block 3 by two cross screws. The interior of the fixing sleeve 51 is reserved with installation space to accommodate the torsion spring 52. Made of 65Mn spring steel, one end of the spring is fixedly installed inside the lower part of the fixing sleeve 51 by welding, and the other end is fixedly connected to one side of the elastic connecting piece 53 by a snap-fit. The elastic coefficient of the torsion spring 52 has been optimized to ensure that it can provide sufficient clamping force without damaging the circuit 21. The elastic connecting piece 53 is made of phosphor bronze, which has good elasticity and conductivity. Its other side is fixed to the outside of the arc-shaped clamping sleeve 54 by laser welding. The arc-shaped clamping sleeve 54 is made of copper alloy, specifically tin bronze alloy. This material not only has good elastic recovery ability, but also maintains a stable clamping shape after long-term use. The inner curvature of the arc-shaped clamping sleeve 54 is designed to be 120°, which completely fits the outer contour of the industrial control circuit 21. On the inner side of the arc-shaped clamping sleeve 54, a layer of soft pad 55 is also attached with high-temperature resistant adhesive. The soft pad 55 is made of silicone rubber and has a fine anti-slip texture on the surface, which can enhance the grip on the circuit 21. The clamping friction prevents the line 21 from shifting during initial positioning and protects the outer insulation layer of the line 21 from being scratched by the arc-shaped clamping sleeve 54. Example

[0019] Please see Figure 1 as well as Figure 2Based on Embodiment 1, this embodiment further specifies that a sealing cover 6 is fitted and installed on the outside of each wiring trough 2. The sealing cover 6 is made of transparent polycarbonate insulating material, allowing workers to observe the wiring inside the wiring trough 2 through the sealing cover 6. At the same time, the sealing cover 6 and the wiring trough 2 are detachably connected by a snap-fit ​​structure. The snap-fit ​​structure includes elastic claws set on the inside of the sealing cover 6 and slots set on the outside of the wiring trough 2. Pressing the sealing cover 6 will cause the elastic claws to engage with the slots, thus fixing the sealing cover 6. Pulling the sealing cover 6 outward will disassemble it, facilitating future maintenance and repair of the line 21. Example

[0020] Please see Figure 1 as well as Figure 2 Based on Embodiment 1, this embodiment further specifies that a conductive plate is fixedly installed on the terminal block 3 by screws. The conductive plate is made of brass, with one end extending into the wiring hole 4 and tightly fitting against the inner wall of the wiring hole 4, and the other end extending into the switch body 1 through a wire and electrically connected to the measurement circuit inside the switch body 1. The measurement circuit includes a voltage sensor and a current sensor, which can monitor the voltage and current parameters of the line 21 in real time and transmit the data to an external industrial control display through a wire. A control switch 7 is also provided in the middle of the front of the switch body 1. The control switch 7 is a rotary switch, which can realize the on / off control of the circuit by rotating the knob. The surface of the knob is provided with anti-slip texture for easy operation by the operator.

[0021] In the above embodiment, the operator first removes the sealing cover 6 from the outside of the wiring slot 2, then places the wire 21 into the wiring slot 2, and pushes the wire 21 to bring the terminal 22 closer to the wiring hole 4. At this time, the wire 21 will first contact the arc-shaped clamping sleeve 54. The arc-shaped clamping sleeve 54 opens outward under the pushing force of the wire 21, and the torsion spring 52 undergoes elastic deformation. After the wire 21 is placed in place, the torsion spring 52 returns to its original position, driving the arc-shaped clamping sleeve 54 to clamp the wire 21, completing the initial positioning of the wire 21. After that, the operator only needs to use a screwdriver to tighten the terminal 22 to the terminal block 3 with screws to complete the wiring. Finally, the sealing cover 6 is installed back on the outside of the wiring slot 2, and the circuit is controlled by the control switch 7. At the same time, the measuring circuit can monitor the electrical parameters in real time to meet the needs of industrial control equipment.

[0022] The working process of this utility model is as follows: When using this easy-to-wire measuring switch, the operator first prepares the measuring switch by holding the sealing cover 6 on the outside of the wiring slot 2 with both hands. Using the snap-fit ​​structure between the sealing cover 6 and the wiring slot 2, the operator pulls or presses the sealing cover 6 outward to remove it from the outside of the wiring slot 2, so that the wiring base 3, wiring hole 4 and elastic clamping assembly 5 inside the wiring slot 2 are fully exposed, leaving space for subsequent wiring operations. Then, the wire 21 to be connected is aligned with the exposed wiring slot 2, and the wire 21 is slowly placed into the wiring slot 2. The wire 21 is pushed so that the wiring terminal 22 at the bottom of the wire 21 moves closer to the wiring hole 4 on the wiring base 3. During this process, the wire 21 first contacts the arc-shaped clamping sleeve 54 in the elastic clamping assembly 5 on one side of the wiring base 3. The arc-shaped clamping sleeve 54 opens outward under the pushing force of the wire 21, driving the elastic connecting piece 53 fixedly connected to the outside of the arc-shaped clamping sleeve 54. The deformation causes the torsion spring 52 fixed on one side of the elastic connecting piece 53 (the other end is fixed inside the lower part of the fixing sleeve 51) to undergo elastic deformation. After the line 21 is placed in the preset position (the terminal 22 is aligned with the wiring hole 4), the pushing of the line 21 is stopped, the torsion spring 52 releases its elastic force, causing the elastic connecting piece 53 to return to its original position, and the arc-shaped clamping sleeve 54 clamps the line 21. At this time, the soft pad 55 on the inner side of the arc-shaped clamping sleeve 54 enhances the friction with the line 21 through the anti-slip texture, completing the initial positioning of the line 21 and preventing the line 21 from shifting. After the line 21 is initially positioned, the operator does not need to hold the fixed line 21. Instead, the operator can directly use a screwdriver to fasten the terminal 22 at the bottom of the line 21 to the wiring hole 4 on the terminal block 3 with screws, so that the terminal 22 and the inner wall of the wiring hole 4 are tightly fitted. At the same time, the conductive piece on the terminal block 3 that is connected to the wiring hole 4 simultaneously contacts the terminal 22, laying the foundation for the subsequent power supply of the measurement circuit, achieving the dual fixing effect of "preliminary positioning + screw tightening", ensuring the connection stability of the line 21. After the terminal 22 is tightened to the wiring hole 4, the removed sealing cover 6 is reinstalled on the outside of the wiring groove 2, and the sealing cover 6 is fixedly attached to the wiring groove 2 by the snap-fit ​​structure.At this time, the sealing cover 6 can protect the internal terminal block 3, line 21 and elastic clamping assembly 5, preventing dust and moisture from entering. At the same time, the insulating coating on the inner wall of the wiring groove 2, together with the insulating sealing cover 6, further prevents leakage between line 21 and switch body 1, improving safety. After the protective installation is completed, the circuit can be controlled by operating the control switch 7 on the switch body 1. When the circuit is on, the conductive plate on the terminal block 3 transmits the current / voltage signal of line 21 to the measurement circuit (including voltage sensor and current sensor) inside the switch body 1. The measurement circuit monitors the electrical parameters. The monitoring data can be output through external devices, allowing operators to monitor the circuit operation status in real time and complete the core function of "control + measurement".
