Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a device for quick connection of mining terminal blocks. Background Technology

[0002] The electrical connections of all terminal blocks must be manually made externally using cables, which consumes a significant amount of manpower, especially in the confined space of the control box, where manual wiring is extremely time-consuming and labor-intensive. Normally, the inspection after the control box is manufactured is an indispensable part of the entire production process and is crucial for ensuring the quality of the control box. Therefore, the commissioning of the control box is inefficient due to the large amount of manpower and time required by the externally connected terminal block debugging cables, necessitating improvements in wiring efficiency to ensure efficient commissioning. Summary of the Invention

[0003] This invention is based on the inventor's discovery and understanding of the following facts and problems: the efficiency of connecting and debugging cables with terminal blocks is low. This invention aims to at least partially solve one of the technical problems in the related art. To this end, embodiments of this invention propose a device for quick connection of mining terminal blocks, which has the advantages of rapid and stable connection.

[0004] According to an embodiment of the present invention, a device for quick connection of mining terminal blocks includes a probe base, a sealing member, and a positioning mechanism. One end of the probe base is provided with multiple probe holes, with each probe corresponding to one of the probe holes. A first end of each probe protrudes from the probe hole, and a second end of each probe is connected to a lead-out cable. Each probe is slidably connected to the probe base via an adjusting member. The probe base is provided with multiple slots along its circumferential direction. The inner wall of the sealing member is provided with multiple elastic tabs along its circumferential direction. At least a portion of the elastic tabs enter the slots and abut against the probe base. A clamping space is formed between the sealing member and the probe base. The positioning mechanism includes a magnetic element and multiple latching elements. The latching elements are arranged along the circumferential direction of the probe base, and each latching element corresponds to a positioning hole on the side of the terminal block. The latching elements enter the positioning holes to fix the probe base. The magnetic element is arranged within the clamping space to magnetically attract and fix the probe base and the terminal block.

[0005] The device for quick connection of mine terminals according to embodiments of the present invention has the advantages of rapid and stable connection. This application has the following advantages: Dual fixation is achieved through the cooperation of a snap-fit ​​component and a magnetic component, improving the stability of the connection between the probe holder and the terminal, and allowing for quick disassembly and installation. The magnetic component enables pre-positioning of the terminal and the probe holder, while the snap-fit ​​component provides mechanical fixation, resisting the impact of vibration on both. The snap-fit ​​component and the magnetic component work together to fix the terminals, and the snap-fit ​​process slows down the magnetic adsorption speed through friction, preventing the terminal from impacting the probe holder. The barbed structure of the snap-fit ​​component copes with strong vibration environments, improving the locking effect compared to conventional snap-fits, and mitigating the impact risk from strong magnetic adsorption. The resistance of the snap-fit ​​entering the positioning hole forms a buffer, preventing probe collision damage—a feature not considered in conventional snap-fits. The snap-fit ​​component, combined with magnetic pre-positioning, allows for quick engagement without visual inspection, adapting to confined underground spaces and operation with gloves.

[0006] The magnetic attraction of the magnetic components allows for rapid pre-positioning, and the arrangement of the magnetic components within the clamping space reduces the risk of dust entering through gaps and causing poor contact.

[0007] In some embodiments, the end of the elastic paddle away from the closure is inclined toward the axis of the closure, and the closure is provided with a transparent viewing window corresponding to the paddle.

[0026] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0027] According to an embodiment of the present invention, a device for quick connection of mining terminal blocks is provided. The device includes a probe base 1, a sealing member 3, and a positioning mechanism. One end of the probe base 1 is provided with a plurality of probe holes 13, and probes 2 correspond one-to-one with the probe holes 13. The first end of each probe 2 protrudes from a probe hole 13, and the second end of each probe 2 is connected to a lead-out cable 6. The probes 2 are connected to the lead-out cable 6 via an adjusting member 7. The probe base 1 is slidably connected. The probe base 1 is provided with multiple slots along the circumferential direction. The inner wall of the sealing member 3 is provided with multiple elastic tabs along the circumferential direction. At least some of the elastic tabs enter the slots and abut against the probe base 1. A clamping space is formed between the sealing member 3 and the probe base 1. The positioning mechanism includes a magnetic member 4 and multiple latching members. The multiple latching members are arranged in the circumferential direction of the probe base 1. The latching members are arranged one-to-one with the positioning holes on the side of the terminal block. The latching members enter the positioning holes to fix the probe base 1. The magnetic member 4 is arranged in the clamping space to magnetically attract and fix the probe base 1 and the terminal block.

[0028] Multiple probes 2 are arranged at the end of the probe holder 1, ensuring multi-point contact with the terminal block and improving the stability and reliability of the connection. The first end of the probe 2 protrudes from the probe hole 13 of the probe holder 1, facilitating quick insertion into the hole of the terminal block for rapid connection. The protrusion length of the probe 2 can be adjusted by sliding relative to the probe holder 1 via the adjusting piece 7, which can adapt to the wiring requirements of different specifications of terminal blocks, ensuring a full connection and avoiding incomplete connections.

[0029] The elastic lever and the locking slot work together to lock the closure 3 to the probe seat 1. The elastic lever can be an arc-shaped piece or an L-shaped bent piece. One end of the elastic lever is connected to the inner wall of the closure 3, and the other end is a free end. The elastic lever has a certain elastic deformation allowance. When the closure 3 is tightened with the probe seat 1, the lever can be bent by the outer surface of the probe seat 1. When rotated to the locking slot position, it quickly resets and locks into the slot under its own elastic force. The cross-section of the slot in the axial direction of the probe seat 1 is triangular. The side of the slot facing the rotation direction of the closure 3 is an inclined plane, and the other side is a vertical plane. The elastic lever slides into the slot from the inclined plane and abuts against the vertical plane, thereby preventing the closure 3 from rotating in the opposite direction. Assembly requires no additional tools. The closure 3 rotates to the preset position and automatically triggers the lever to lock into the slot. During disassembly, a sheet plate is used to gently press along the free end of the lever to disengage it from the slot, at which point the closure 3 can be removed. The elastic lever can be a thin metal sheet with elasticity.

[0030] The positioning mechanism uses magnetic component 4 to magnetically attract the steel plate containing the wiring terminals. The latching component secures the wiring segment to the side by fixing it with the positioning hole on the side of the wiring terminal. The magnetic attraction and latching component form a double fixation, ensuring a firm connection between the probe holder 1 and the wiring terminal and preventing loosening due to vibration or external force. The positioning mechanism enables quick connection between the probe holder 1 and the wiring terminal, facilitating rapid verification of the wiring and reducing wiring time. The connection between the cable and the probe 2 of the probe holder 1 does not require repeated disassembly and installation. The cooperation between magnetic component 4 and the latching component ensures a stable connection of the probe holder 1, ensuring safety. The latching component can be a plastic or metal part with a certain mechanical strength and elasticity.

[0031] The device for quick connection of mining terminals according to embodiments of the present invention has the advantages of fast connection and stable connection.

[0032] In some embodiments, the end of the elastic lever away from the closure member 3 is inclined toward the axis of the closure member 3, and the closure member 3 is provided with a transparent observation window corresponding to the lever.

[0033] Specifically, the free end of the elastic lever is inclined towards the axis of the sealing member 3 at an angle of 15°-25°. The free end naturally points towards the center. When the sealing member 3 is connected to the probe base 1, the free end of the lever first contacts the outer surface of the probe base 1. As the sealing member 3 rotates and tightens, the lever undergoes elastic deformation due to the pressure exerted by the probe base 1 surface at the inclined angle, accumulating elastic potential energy during the deformation process. A transparent observation window is located on the outer wall of the sealing member 3, corresponding one-to-one with the elastic lever, facilitating observation of the deformation and position of the elastic lever and making it easier to align the elastic lever during subsequent disassembly. The lever's "automatic alignment - compression deformation - spring into the slot" action can be achieved by rotating the sealing member 3, eliminating the need for mechanical assistance, reducing assembly difficulty, and improving assembly efficiency. The observation window, made of highly transparent material, allows for direct visualization of whether the lever is fully inserted into the slot, enabling users to determine if the working status is normal without disassembling the device.

[0034] In some embodiments, the adjusting member 7 includes a first spring 71 and a spring cover 70. At least a portion of the spring cover 70 enters the probe hole 13 and is connected to the probe seat 1. The two ends of the first spring 71 are respectively connected to the second end of the probe 2 and the spring cover 70. The spring cover 70 is provided with an internal thread in the circumferential direction. At least a portion of the first end of the spring cover 70 enters the probe hole 13 and is threadedly connected to the probe hole 13.

[0035] Specifically, the threaded connection between the spring cover 70 and the probe hole 13 allows the extension length of the probe 2 to be precisely adjusted by rotating the spring cover 70. By rotating the spring cover 70, the pushing distance of the spring on the probe 2 can be adjusted. The elastic support of the first spring 71 can provide a certain preload, ensuring a tighter contact between the probe 2 and the terminal block and reducing the occurrence of loose connections. Rotating the spring cover 70 can adjust the preload of the first spring 71.

[0036] In some embodiments, an axial reference line is provided at the end of the spring cover 70 away from the probe 2, and a fixed reference line is provided around the edge of the probe hole 13.

[0037] Specifically, the axial reference line on the spring cover 70 and the fixed reference line on the probe holder 1 facilitate the user's judgment of the rotation angle and number of rotations of the spring cover 70. Different colored scales are set on the axial reference line to facilitate the user's judgment of distance. The range of the digital scale can be designed according to the maximum and minimum extension length of the probe 2 to ensure that the operator can make precise adjustments throughout the adjustment range. By observing the axial reference line in conjunction with the surface of the probe holder 1, the protrusion dimension of the spring cover 70 can be obtained. By observing the number of rotations of the spring cover 70 relative to the fixed reference line, the tightening depth of the spring cover 70 can be determined. By observing the alignment of the two reference lines, the operator can quickly determine whether the extension length of the probe 2 has reached the expected value.

[0038] In some embodiments, a barb is provided at the end of the latching member away from the probe base 1, and at least part of the barb enters the positioning hole and hooks onto its hole wall, and the axial direction of the positioning hole intersects with the axial direction of the probe base 1.

[0039] Specifically, the barbs on the latching components allow them to securely hook onto the positioning hole wall of the terminal block, providing additional mechanical locking force and ensuring a stable connection between the probe holder 1 and the terminal block under various harsh conditions (such as vibration and impact). The barbs reduce errors caused by manual operation, ensuring that each latching component accurately enters the positioning hole and hooks onto the terminal block, thus improving the overall quality of the connection.

[0040] The axial direction of the positioning hole intersects with the axial direction of the probe base 1, making the positioning hole an oblique hole on the terminal block, which facilitates the hook of the fastener to be hooked onto the positioning hole.

[0041] The buckle is made of elastic material. Moving the buckle separates the barb from the positioning hole, allowing for quick disassembly and easy maintenance and replacement. The hook-and-positioning mechanism reduces relative movement between the buckle and the positioning hole, thus reducing wear and extending the lifespan of both. The elastic material of the barb allows it to adjust its angle when inserted into the positioning hole, ensuring reliable engagement at various insertion angles.

[0042] In some embodiments, a sheath is also included, which is fitted over the first end of the probe 2 and is slidably connected to the probe seat 1 to change the exposed length of the probe 2.

[0043] Specifically, the sheath effectively protects the first end of probe 2 from damage caused by collisions or scratches during transportation, storage, or operation. The sheath reduces oxidation and contamination on the surface of probe 2, thereby lowering contact resistance and reducing infrequent connections. The slidable connection between the sheath and probe holder 1 allows the exposed length of probe 2 to be adjusted according to actual connection requirements. This increases the flexibility of the device, enabling it to adapt to different specifications of wiring terminals. When not connected, the sheath completely covers the first end of probe 2, preventing accidental contact with live parts by operators and improving operational safety.

[0044] In some embodiments, a second spring is provided at one end of the sheath adjacent to the probe seat 1. The second spring is connected to the probe seat 1 to push the sheath away from the probe seat 1.

[0045] Specifically, the spring's elastic deformation allows the sheath to automatically return to its original position when not in use, that is, it automatically slides to the end of the probe holder 1, completely covering the first end of the probe 2. This prevents the probe 2 from being exposed when not connected, improving operational safety and convenience. It reduces the need for operators to manually adjust the sheath position, lowering the risk of connection errors or damage due to misoperation. Driven by the spring's elasticity, the sheath always tightly covers the first end of the probe 2, maintaining protection even in environments of vibration or impact, preventing wear and contamination of the probe 2's surface.

[0046] The sheath is a hollow tubular component with an inner diameter slightly larger than that of probe 2, allowing the sheath to move relative to probe 2. One end of the second spring is fixedly connected to the probe holder, and the other end is fixedly connected to the end of the sheath. The free end of the sheath points towards the terminal block. The second spring maintains a certain preload, and when it recovers its deformation, it pushes the sheath towards probe 2 and the terminal block. Understandably, at least a portion of the second spring and probe 2 are within the probe holder, with the second spring positioned in the gap between the probe holder and the probe.

[0047] The relationship between the movement of the sheath and the second spring: When not in use, probe 2 is not connected to the terminal block; the second spring extends, pushing the sheath towards the side of the probe holder adjacent to the terminal block. Figure 1 Slide it to the right as shown in the diagram until the front end of the sheath completely covers the first end of probe 2, at which point probe 2 is not exposed at all; In use: The operator presses the sheath towards the probe seat by hand or with the help of the end face of the terminal block. The second spring is compressed, and the sheath slides backward and retracts into the gap between the probe seat and the probe 2. The first end of the probe is gradually exposed until it can be inserted into the hole of the terminal block. After the terminal block is removed, the sheath will move on its own under the drive of the second spring to cover the surface of the probe 2.

[0048] After connection: When probe 2 is inserted into the terminal block, the free end of the sheath is blocked by the terminal block's outer shell and cannot move or reset (the second spring remains compressed). At this time, the sheath fits between the terminal block and the probe holder, neither affecting probe contact nor obstructing the connection between the probe and the terminal. In the dusty environment of underground mines, probes are exposed for extended periods, which can easily lead to poor contact due to dust accumulation, and may also cause electric shock or probe bending damage due to accidental contact. The sheath automatically resets, passively exposing probe 2 under external force, thus improving safety.

[0049] In some embodiments, the probe holder 1 includes a first cylinder 10 and a second cylinder 11 that are coaxial. The first cylinder 10 and the second cylinder 11 are joined together in the axial direction. The diameter of the first cylinder 10 is larger than the diameter of the second cylinder 11 to form a stepped boss. The first cylinder 10 is provided with an external thread in the circumferential direction. The closure 3 includes a first ring 30 and a second ring 31. The diameter of the first ring 30 is larger than the diameter of the second ring 31. The inner wall of the first ring 30 is provided with an internal thread to mate with the external thread of the first cylinder 10.

[0050] Specifically, the stepped boss formed by the first cylinder 10 and the second cylinder 11 provides additional mechanical support, enhancing the overall strength and stability of the probe holder 1. The external thread on the first cylinder 10 is used for connection with the closure 3, and the probe hole 13 on the second cylinder 11 is used for mounting the probe 2, enabling the probe holder 1 to perform different functions and improving the flexibility and versatility of the device.

[0051] The sealing component 3 is strengthened by the cooperation of the first ring 30 and the second ring 31. The second ring 31 is arranged on the inner wall of the first ring 30, and one end face of the second ring 31 is flush with the end face of the first ring 30. The cooperation of the two rings makes it easy for personnel to identify the direction and ensures that the sealing component 3 can be tightened correctly during installation. The operation is simple. The two rings play different functions. The first ring 30 is used for connection and fixation, and the second ring 31 is used for sealing to effectively prevent dust, moisture and other impurities from entering the clamping space between the sealing component 3 and the probe seat 1.

[0052] Optionally, a sealing ring mounting groove is provided on the inner wall of the second ring 31 for mounting the sealing ring. The sealing ring can further improve the sealing performance of the device and prevent dust and moisture from entering.

[0053] In some embodiments, the probe hole 13 includes a first segment and a second segment, the diameter of the first segment being smaller than the diameter of the second segment, the first segment being arranged on the first cylinder 10, and the second segment being arranged on the second cylinder 11. The probe 2 includes a third cylinder 20 and a fourth cylinder 21. The third cylinder 20 and the fourth cylinder 21 are joined together in the axial direction. The diameter of the third cylinder 20 is smaller than the diameter of the fourth cylinder 21 to form a stepped boss. The third cylinder 20 enters the first section, and the fourth cylinder 21 enters the second section. The plane of the end of the fourth cylinder 21 away from the third cylinder 20 is connected to the lead cable 6. The spring cover 70 includes a fifth cylinder 701 and a sixth cylinder 702, which are joined together in the axial direction. The diameter of the fifth cylinder 701 is smaller than that of the sixth cylinder 702, forming a stepped boss. The fifth cylinder 701 is provided with external threads in the circumferential direction. The sixth cylinder 702 is provided with a first groove 72 and a second groove 73 that are connected to each other at the end away from the fifth cylinder 701. The depth of the first groove 72 is greater than that of the second groove 73. The fifth cylinder 701 and the sixth cylinder 702 are provided with through holes 5.

[0054] Specifically, the segmented probe 2 ensures structural strength while allowing for more precise installation within the probe hole 13, reducing poor contact or intermittent connection caused by improper installation.

[0055] The external thread on the fifth cylinder 701 of the spring cover 70 is used to connect with the probe holder 1, and the groove on the sixth cylinder 702 is used to install the adjustment tool. This segmented design allows the spring cover 70 to perform different functions, improving the flexibility and versatility of the device. The groove facilitates cable routing within the groove and secures the spring cover 70. The groove is a straight groove. The through holes 5 on the fifth cylinder 701 and the sixth cylinder 702 facilitate the entry and exit of the probe 2 and the lead cable 6, and the diameter of the through holes 5 is adapted to the diameter of the lead cable 6.

[0056] The first groove 72 and the second groove 73 are perpendicular to each other. The first groove 72 is used for cable routing, and the second groove 73 is used to fix the spring cover 70. The spring cover 70 can be rotated using a screwdriver or other tools. The deeper grooves can protect and limit the cable movement. The through hole 5 passes through the intersection of the first groove 72 and the second groove 73, facilitating cable entry and exit and reducing connection failures caused by loose cables or slippage of the spring cover 70. Different colors can be used to mark grooves of different depths for quick identification by operators.

[0057] In some embodiments, the outer surface of the first ring 30 is provided with anti-slip texture, and the outer surface of the first ring 30 is provided with a plurality of protrusions, which are arranged in a triangle to indicate the direction of rotation.

[0058] Specifically, the anti-slip texture significantly increases the friction between the operator and the first ring 30, preventing slippage due to wetness during operation and ensuring operational stability and safety. Multiple protrusions arranged in a triangular pattern visually indicate the direction of rotation, helping operators quickly identify tightening and loosening directions, reducing errors and improving work efficiency. The triangular array of protrusions refers to multiple rows of protrusions arranged circumferentially, with one protrusion in the first row, and the number of protrusions increasing sequentially from the second row. The arrangement direction is the width of the anti-slip texture, with the apex of the triangle pointing in the direction of rotation. The protrusions provide tactile feedback, allowing the operator to determine the direction of rotation by touch. This eliminates the need for visual judgment, reducing errors. The anti-slip texture uses a full-circumference distributed diamond pattern or vertical stripes, with a depth of 1-2 mm to increase friction between the glove and the first ring 30.

[0059] In some embodiments, a sealing ring is also included, which is arranged between the closure 3 and the probe seat 1 to increase the sealing performance, and the sealing ring is in contact with the second ring 31.

[0060] Specifically, the sealing ring effectively prevents dust, moisture, and other impurities from entering the clamping space between the sealing component 3 and the probe holder 1, protecting internal components and improving the reliability and durability of the device. The sealing ring creates a uniform pressure distribution between the sealing component 3 and the probe holder 1, ensuring a tight and stable connection and reducing direct friction between them. The sealing ring is made of wear-resistant rubber, silicone, or other materials to enhance sealing performance. Through elastic deformation, the sealing ring prevents fine dust from entering the clamping space, affecting the magnetic attraction of the components and the cleanliness of the probe surface, and prevents moisture intrusion, thus preventing internal metal components from rusting.

[0061] In some embodiments, the first end of the probe 2 is a spherical protrusion, and a wear indicator mark is provided on the probe 2.

[0062] Specifically, the spherical protrusion concentrates the pressure at the contact point, resulting in a tighter contact between probe 2 and the terminal block, preventing incomplete connections caused by poor contact. The spherical protrusion design also reduces the contact area, lowers contact resistance, and improves conductivity. The curvature of the spherical protrusion surface allows for automatic centering after insertion.

[0063] Wear indicator marks are provided on probe 2. When probe 2 wears to a certain extent, the marks will appear, reminding the operator to replace probe 2 in time. This effectively avoids poor contact caused by probe 2 wear and extends the service life of probe 2. The wear indicator marks can be scale lines at predetermined intervals on probe 2, or a coating color, etc. When probe 2 wears to the scale line or the color disappears, probe 2 needs to be replaced.
