Description

Technical Field

[0001] This utility model belongs to the field of equipment interface technology, and more specifically, relates to an auxiliary wiring mechanism for a monitoring instrument. Background Technology

[0002] In existing technologies, online monitoring equipment is widely used in power systems, industrial automation, environmental monitoring, and other fields. These devices need to be connected to external signal cables or power cables via wiring ports. The reliability of the wiring port connection directly affects the normal operation of the equipment and the quality of data transmission. Traditional wiring port structures often use simple plug-in connections or screw crimping methods, which frequently result in problems such as poor contact, loosening and detachment, and water ingress during actual use. Especially in harsh outdoor environments, factors such as temperature changes, vibration and impact, and rain erosion further exacerbate these problems, leading to increased equipment failure rates and higher maintenance costs. In other words, existing technologies suffer from technical problems such as insufficient clamping force, poor sealing performance, and inconvenient installation. Utility Model Content

[0003] In view of this, the present invention provides an auxiliary wiring mechanism for a monitoring instrument, which can solve the technical problems of insufficient clamping force, poor sealing performance and inconvenient installation in the auxiliary wiring mechanism of the monitoring instrument in the prior art.

[0004] This utility model is implemented as follows:

[0005] This utility model provides an auxiliary wiring mechanism for a monitoring instrument, including a base, a terminal block on the base, a wire connector inserted into the terminal block, a clamping device for fixing the wire connector, a sealing ring around the base, and a protective cover covering the terminal block. The clamping device includes a first clamping arm and a second clamping arm arranged opposite to each other, forming a clamping cavity between the two clamping arms. When the wire connector is inserted into the clamping cavity, the first clamping arm and the second clamping arm generate a clamping force of twice the distance.

[0006] The technical effects of the auxiliary wiring mechanism for a monitoring instrument provided by this utility model are as follows: the clamping cavity is formed by the first clamping arm and the second clamping arm, and a clamping force of double distance is generated when the wire connector is inserted, ensuring that a stable mechanical and electrical connection is formed between the wire connector and the terminal block, thereby improving the reliability and stability of the wiring.

[0007] Based on the above technical solution, the auxiliary wiring mechanism of the monitoring instrument of this utility model can be further improved as follows:

[0008] The first clamping arm and the second clamping arm are connected by an elastic connector. The elastic connector has an arc-shaped structure. When the wire connector is inserted, the elastic connector undergoes elastic deformation, causing the two clamping arms to generate a contact force.

[0009] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the elastic connector uses an arc-shaped structure to connect the two clamping arms. When the wire connector is inserted, the elastic connector generates elastic deformation, providing a continuous elastic resistance force to the clamping arms, keeping the clamping force stable, and avoiding poor contact caused by vibration or temperature changes.

[0010] Furthermore, the inner side of the first clamping arm is provided with a first contact protrusion, and the inner side of the second clamping arm is provided with a second contact protrusion. The two contact protrusions are arranged opposite to each other and form multi-point contact with the outer surface of the wire connector.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the contact protrusions on the inner side of the clamping arm form multiple points of contact with the outer surface of the wire connector, increasing the contact area and contact pressure, improving the stability of the electrical connection, reducing contact resistance, and preventing poor contact or overheating problems caused by single-point contact.

[0012] Furthermore, the terminal block has a guide groove inside, the width of which gradually decreases along the insertion direction, and the wire connector is guided when inserted along the guide groove.

[0013] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the width of the guide groove gradually decreases along the insertion direction, providing a guiding effect for the wire connector, enabling the wire connector to be smoothly inserted into the correct position, avoiding skewing or jamming during the insertion process, and improving the convenience and accuracy of installation.

[0014] Furthermore, the sealing ring has an annular structure with an inner diameter smaller than the outer diameter of the wire connector. When the wire connector is inserted, the sealing ring undergoes radial compression deformation, tightly fitting against the outer surface of the wire connector.

[0015] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the inner diameter of the sealing ring is smaller than the outer diameter of the wire connector, and radial compression deformation occurs when it is inserted, which tightly fits the outer surface of the wire connector, forming an effective waterproof and dustproof seal, protecting the inside of the wiring port from the influence of the external environment, and improving the environmental adaptability of the equipment.

[0016] Furthermore, the protective cover is equipped with an observation window made of transparent material, which allows observation of the connection status inside the terminal block.

[0017] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the observation window on the protective cover is made of transparent material, which allows for direct observation of the connection status inside the terminal block, facilitating installation, debugging, maintenance and inspection, timely detection of wiring problems, and improving the efficiency and accuracy of equipment maintenance.

[0018] Furthermore, the base is provided with fixing holes, and the fixing holes are threaded, so that the entire wiring structure can be fixed to the equipment housing by bolts.

[0019] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the fixing holes on the base are provided with threads, and the entire wiring port structure is fixed by bolts, ensuring the secure installation of the wiring port on the equipment housing, preventing loosening caused by vibration or external force, and ensuring the positional stability of the wiring port.

[0020] Furthermore, the distance between the first clamping arm and the second clamping arm in their natural state is greater than the outer diameter of the wire connector, and the two clamping arms rotate and deform when the wire connector is inserted.

[0021] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the spacing between the clamping arms in the natural state is greater than the outer diameter of the wire connector, and rotational deformation occurs during insertion. This design makes the wire connector insertion process smoother, and at the same time, a reliable clamp is formed after insertion, balancing the convenience of installation and the reliability of connection.

[0022] Furthermore, the elastic modulus of the elastic connector is 1000-5000 MPa, ensuring that the clamping arm generates appropriate clamping force.

[0023] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the elastic modulus of the elastic connector is controlled within the range of 1000 to 5000 MPa, ensuring that the clamping arm generates appropriate clamping force, which not only ensures sufficient contact pressure, but also avoids excessive clamping force that could cause deformation or damage to the wire connector, thus achieving the best clamping effect.

[0024] Furthermore, the inlet width of the guide groove is 1.2 times the outer diameter of the wire connector, and the outlet width is 0.95 times the outer diameter of the wire connector.

[0025] Compared with the prior art, the beneficial effects of the auxiliary wiring mechanism for a monitoring instrument provided by this utility model are as follows: This utility model forms a clamping cavity by setting up opposing first and second clamping arms, using elastic connectors to provide continuous elastic resistance, setting contact protrusions on the inner side of the clamping arms to form multi-point contact, and combining the guiding effect of the guide groove, the sealing effect of the sealing ring, and the protective function of the protective cover, thus solving the technical problems of insufficient clamping force, poor sealing performance, and inconvenient installation in the prior art, and significantly improving the connection reliability, sealing performance, and ease of use of the wiring port.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0034] like Figure 1-4As shown, this utility model provides an auxiliary wiring mechanism for a monitoring instrument, including a base 1, a terminal block 2 disposed on the base 1, a wire connector 3 inserted into the terminal block 2, a clamping device 4 for fixing the wire connector 3, a sealing ring 5 disposed around the base 1, and a protective cover 6 covering the terminal block 2. The clamping device 4 includes a first clamping arm 7 and a second clamping arm 8 disposed opposite to each other, forming a clamping cavity 9 between the two clamping arms. When the wire connector 3 is inserted into the clamping cavity 9, the first clamping arm 7 and the second clamping arm 8 generate a clamping force of double the distance. The first clamping arm 7 and the second clamping arm 8 are connected by an elastic connector 10. The elastic connector 10 has an arc-shaped structure with an arc angle of 120° to 180° and a thickness of 1 to 3 mm. When the wire connector 3 is inserted, the elastic connector 10 undergoes elastic deformation of 2 to 8 mm, causing the two clamping arms to generate a contact force. The inner side of the first clamping arm 7 is provided with a first contact protrusion 11, and the inner side of the second clamping arm 8 is provided with a second contact protrusion 12. The two contact protrusions are arranged opposite each other, with a protrusion height of 0.5-2mm, forming multi-point contact with the outer surface of the wire connector 3, and the contact pressure is 50-200N. The terminal block 2 is provided with a guide groove 13 inside. The width of the guide groove 13 gradually decreases along the insertion direction, with an inlet width of 15-25mm, an outlet width of 8-12mm, and a groove depth of 20-40mm. When the wire connector 3 is inserted along the guide groove 13, it generates a guiding effect. The sealing ring 5 is an annular structure, made of nitrile rubber or silicone rubber, with an inner diameter of 6-10mm, an outer diameter of 12-18mm, and a thickness of 2-4mm. When the wire connector 3 is inserted, the sealing ring 5 undergoes radial compression deformation with a compression rate of 10-30%, and fits tightly against the outer surface of the wire connector 3. The protective cover 6 is equipped with an observation window made of transparent polycarbonate or acrylic material, with a thickness of 2-5mm and a light transmittance greater than 85%, allowing observation of the connection status inside the terminal block 2. The base 1 has mounting holes with threads of M6-M12, which are used to fix the entire wiring structure to the equipment housing with bolts, with a fixing torque of 15-25 N·m.

[0035] The production process of this solution is as follows: First, the base 1 is manufactured by casting or machining, using aluminum alloy or stainless steel, and the surface is anodized or electroplated. The terminal block 2 is manufactured by injection molding, using flame-retardant engineering plastics such as polyamide or polycarbonate. The first clamping arm 7 and the second clamping arm 8 are manufactured by stamping, using spring steel or stainless steel, and the surface is galvanized or nickel-plated. The elastic connector 10 is manufactured by bending, using spring steel with an elastic modulus of 1000-5000 MPa. The sealing ring 5 is manufactured by vulcanization. The protective cover 6 is manufactured by injection molding or die casting. Finally, the components are assembled into a complete wiring port structure according to the design requirements. In use, the wire connector 3 is inserted along the guide groove 13, the elastic connector 10 deforms, the clamping arms 7 and 8 clamp the wire connector 3, the sealing ring 5 forms a seal, and the protective cover 6 provides protection.

[0036] Compared to existing technologies, this solution achieves reliable fixing and electrical connection of the wire connector through a mechanical structure design with double-arm clamping and elastic connection. The clamping force is evenly distributed and consistently stable, avoiding the localized stress concentration and loosening problems that can occur with traditional screw crimping methods. The multi-point contact design increases the contact area, reduces contact resistance, and improves the stability of the electrical connection. The gradient structure of the guide groove makes the insertion process smoother and reduces installation difficulty. The radial compression sealing method of the sealing ring forms a reliable waterproof and dustproof barrier, adapting to various harsh environments. The observation window design facilitates maintenance and inspection, improving the maintainability of the equipment.

[0037] Based on the above implementation method, another implementation method is obtained by changing the shape and connection method of the clamping arms: the first clamping arm 7 and the second clamping arm 8 adopt a curved plate structure with a plate thickness of 1.5-3mm, a width of 8-15mm, and a length of 25-40mm. The two clamping arms are connected by a flexible hinge with a thickness of 0.3-0.8mm and a width of 3-6mm, replacing the original elastic connector 10. The shape of the clamping cavity 9 is changed from the original circle to an ellipse or polygon to accommodate wire connectors 3 of different shapes. The shape of the contact protrusions 11 and 12 is changed from the original semicircle to a trapezoid or triangle, with a protrusion spacing of 3-8mm and a number of 3-6 protrusions. The cross-sectional shape of the guide groove 13 is changed from the original rectangle to a trapezoid or arc shape, with a groove wall inclination angle of 5°-15° to provide better guiding effect. The sealing ring 5 adopts a double-layer structure, with the inner layer being a soft material and the outer layer being a hard material. The thickness of the inner layer is 1-2 mm and the thickness of the outer layer is 1-1.5 mm, forming a double sealing effect.

[0038] The improved production or usage process is as follows: the clamping arm is manufactured using precision stamping technology to ensure the dimensional accuracy of the flexible hinge part, and the surface roughness is controlled below Ra1.6; the contact protrusion is manufactured using precision forming technology to ensure shape consistency; the double-layer sealing ring is manufactured using a secondary vulcanization process to ensure a firm bond between the inner and outer layers; special tooling is required during assembly to ensure the positional accuracy of each component; the insertion force is 20-50N and the extraction force is 30-80N during use, meeting the requirements for easy operation and reliable connection.

[0039] The improvement over the first solution lies in the flexible hinge connection, which provides a more precise center of rotation, making the movement of the clamping arm more stable and controllable, and resulting in better consistency of clamping force. The elliptical or polygonal clamping cavities can accommodate a wider variety of wire connectors, improving versatility. Trapezoidal or triangular contact protrusions offer stronger gripping ability, especially for smooth-surfaced wire connectors. Trapezoidal or arc-shaped guide grooves reduce insertion resistance and improve guiding accuracy. The double-layer sealing ring structure provides more reliable sealing performance; even if one layer fails, the other layer maintains its sealing effect. Compared to existing technologies, the improved solution further enhances connection reliability, versatility, and sealing performance, reduces failure rates and maintenance costs, and extends equipment lifespan.

[0048] Specifically, the principle of this invention is as follows: A clamping cavity is formed by the relative movement between the first and second clamping arms.

The gradient structure of the guide groove guides the wire connector to be accurately inserted into the designed position. The radial compression deformation of the sealing ring forms a circumferential seal, and the protective cover provides external protection. The entire structure achieves automatic clamping and sealing through mechanical deformation and elastic recovery, requiring no external power source. It is simple, reliable, and easy to maintain, making it suitable for online monitoring equipment in various harsh environments.
