Description

Technical Field

[0001] This invention relates to the field of plug-in pressure plate technology, and more particularly to a connector fixing device for plug-in pressure plate terminals. Background Technology

[0002] A plug-in type pressure plate is a common type of hard pressure plate for relay protection devices and a common electrical circuit break point. Existing plug-in type pressure plates have a pair of terminals for connecting external lines. The terminals consist of an insulating base, a metal washer, and a wiring screw. When wiring, the wiring screw on the terminal needs to be unscrewed, the external terminal is inserted into the terminal, and then the wiring screw is screwed into the terminal to complete the line connection.

[0003] However, when using existing plug-in pressure plates for wiring, not only is the wiring efficiency low due to repeated screw tightening, but also the narrow wiring space makes it easy to accidentally touch the plate when the pressure plate is energized. This can affect the normal operation of the protection device and even threaten the personal safety of the operator, posing a significant safety hazard. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a pluggable pressure plate terminal block wiring fixer, which can effectively improve wiring efficiency, reduce operational hazards, ensure normal operation of the device, and improve personal safety.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a pluggable pressure plate terminal block fixing device, including an insulating claw fixing seat, a wiring screw, a conductive spring and an insulating screw cap. The insulating claw fixing seat is provided with a connecting part and a supporting part. The connecting part is provided with a mounting hole, and the supporting part is provided with a plurality of wire channels. The wiring screw is installed in the mounting hole. One end of the wiring screw facing the supporting part is connected to the conductive spring, and the insulating screw cap is installed on the other end of the wiring screw.

[0006] Furthermore, the support portion includes a plurality of support claws, each of which is spaced apart on the connecting portion, and the gap between two adjacent support claws forms the wire channel.

[0007] Furthermore, the support claw is provided with a powerful magnet for attracting the wiring fastener to the mounting surface.

[0008] Furthermore, the support claw includes a vertical support and a horizontal support, the vertical support and the horizontal support forming an L-shaped structure, the vertical support being connected to the connecting part, and the horizontal support having an installation groove, in which the powerful magnet is installed.

[0009] Furthermore, the sidewall of the vertical support member facing the conductive spring is an arc-shaped concave surface.

[0010] Furthermore, the connecting portion is provided with a clearance portion.

[0011] Furthermore, the insulating screw cap is provided with an anti-slip structure.

[0012] Furthermore, the insulating screw cap is provided with a first wire hole.

[0013] Furthermore, the wiring screw is provided with a fixing washer, and the end of the conductive spring used to connect with the wiring screw is fixed between the wiring screw and the fixing washer.

[0014] Furthermore, an insulating rubber sleeve is provided between the insulating claw fixing seat and the insulating screw cap, and the insulating rubber sleeve is installed on the wiring screw.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] This invention provides a connector for a pluggable pressure plate terminal block, comprising an insulating claw fixing seat, a wiring screw, a conductive spring, and an insulating screw cap. The insulating claw fixing seat has a connecting part and a supporting part. The connecting part has a mounting hole, and the supporting part has a plurality of wire channels. The wiring screw is installed in the mounting hole. One end of the wiring screw facing the supporting part is connected to the conductive spring, and the insulating screw cap is installed on the other end of the wiring screw.

[0017] When using the wiring fastener of this invention, first wrap the external wire around the wiring screw and fix it with the insulating screw cap. After the installation of the external wire and the wiring screw is completed, the wiring fastener can be directly installed around the terminal block of the pressure plate using the insulating claw fixing seat, so that the conductive spring and the terminal block directly abut against each other, and the connection between the external wire and the terminal block is completed by means of the conductive spring and the wiring screw.

[0018] Compared to existing technologies, this invention eliminates the need for repeated disassembly and reassembly of metal screws and terminals for installation. A single connection step allows for seamless connection of external wires to the terminals, improving work efficiency. Furthermore, the invention utilizes the wire channel on the insulating claw mounting base to provide installation space for the existing conductive wiring on the terminals, preventing interference with the original wiring of the pressure plate terminals. Moreover, this invention separates the wiring process from the installation process. During wiring, i.e., while winding the external wire around the terminal screw, there is no need to contact the existing electrical circuit on the terminals. This avoids impacting the original electrical circuit, ensuring equipment operation, and also prevents electric shock to operators, improving operational safety. Attached Figure Description

Detailed Implementation

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The present invention will be described in one embodiment below with reference to specific embodiments. The accompanying drawings are for illustrative purposes only and represent schematic diagrams, not actual pictures, and should not be construed as limiting the present patent. In order to better illustrate the embodiments of the present invention, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the actual product size. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0040] like Figure 1 As shown, this embodiment provides a connector for a pluggable pressure plate terminal block, including an insulating claw fixing seat 1, a wiring screw 2, a conductive spring 3, and an insulating screw cap 4. The insulating claw fixing seat 1 is provided with a connecting part 110 and a supporting part. The connecting part 110 is provided with a mounting hole 7, and the supporting part is provided with a plurality of wire channels 140. The wiring screw 2 is installed in the mounting hole 7. One end of the wiring screw 2 facing the supporting part is connected to the conductive spring 3, and the insulating screw cap 4 is installed on the other end of the wiring screw 2.

[0041] It should be noted that the insulating claw fixing seat 1 is used to support the wiring screw 2 and the conductive spring 3. The wiring screw 2 and the conductive spring 3 are used to connect the external wire 18 and the metal screw 15 respectively, thus conducting the connection circuit. The wiring screw 2 is connected to the external wire 18, and the insulating screw cap 4 is used to fix the external wire 18 to the wiring screw 2 to prevent the external wire 18 from being loosely connected to the wiring screw 2. The conductive spring 3 is used to contact the metal screw 15, and the external wire 18 is connected to the metal screw 15 through the wiring screw 2 and the conductive spring 3. The wire channel 140 on the insulating claw fixing seat 1 is used to leave installation space for the original wiring on the pressure plate terminal to avoid interfering with the original wiring. In this embodiment, in order for the wiring fixer to be fully connected to the pressure plate terminal, the wiring screw 2 and the conductive spring 3 are made of highly conductive metal.

[0042] Meanwhile, in this embodiment, in order to facilitate the external wire 18 to be wound around the wiring screw 2, the wiring screw 2 is provided with a threaded end that extends out of the mounting hole 7 on the insulating claw fixing seat 1 and is set opposite to the support part, so that the external wire 18 can be wound around the wiring screw 2. Then, the insulating screw cap 4 is installed to improve the connection stability between the external wire 18 and the wiring screw 2.

[0043] Furthermore, to ensure sufficient contact between the wiring fastener and the metal screw 15, a conductive spring 3 is installed at the end of the wiring screw 2 located within the support portion of the insulating claw mounting base 1. The conductive spring 3 abuts against the metal screw 15, such as... Figure 7-8 As shown, in order to improve the connection stability between the conductive spring 3 and the metal screw 15 and avoid poor connection, when the conductive spring 3 is not in contact with the metal screw 15, the conductive spring 3 is in its natural state and the length of the conductive spring 3 extends out of the support part of the insulating claw fixing seat 1. When the insulating claw fixing seat 1 is installed around the insulating base 14 of the pressure plate terminal block, the gap between the insulating base 14 of the pressure plate terminal block and the insulating claw fixing seat 1 is much smaller than the length of the conductive spring 3 when it is in its natural relaxed state. At this time, the conductive spring 3 is compressed and firmly pressed against the metal screw 15, so that the external wire 18 is connected to the metal screw 15 through the terminal screw 2 and the conductive spring 3, and the circuit is completed.

[0044] Compared to Figure 16-18 The prior art shown in the figure requires that when wiring the pressure plate terminal, the metal screw 15 must first be loosened and removed, the terminal 16 of the external wire 18 be inserted into the metal screw 15, and then the removed metal screw 15 be tightened and installed back to complete the connection between the terminal 16 of the external wire 18 and the metal screw 15 on the pressure plate terminal. The prior art is not only cumbersome to operate and has low wiring efficiency, but it is also very easy to accidentally touch when working in a confined space, which will affect the normal operation of the protection device and even threaten the personal safety of the operator, posing a great safety hazard.

[0045] The wiring fastener provided by this invention uses a plug-in connection method to replace the wiring method of repeated screw adjustment in the prior art. When using the wiring fastener in this embodiment, the external wire 18 is first wrapped around the wiring screw 2 and fixed with the insulating screw cap 4. This step does not require contact with the live pressure plate, and the external wire 18 can be wrapped in an open working space in advance to avoid accidental contact. After the external wire 18 and the wiring screw 2 are installed, the wiring fastener can be directly installed around the pressure plate terminal insulating base 14 using the insulating claw fixing seat 1, so that the conductive spring 3 and the metal screw 15 directly abut against each other. The external wire 18 and the terminal 14 are connected by the conductive spring 3 and the wiring screw 2.

[0046] In use, this invention allows for one-step connection between the external wire 18 and the metal screw 15, eliminating the need for repeated disassembly and reassembly of the metal screw 15 and its connection to the terminal block 16, thus improving work efficiency. Furthermore, as... Figure 6 As shown, this invention utilizes the wire channel 140 on the insulating claw fixing seat 1 to reserve installation space for the original wiring conductivity on the terminal block 14, avoiding interference with the original wiring of the pressure plate terminal block. At the same time, this invention can separate the wiring process from the installation process. During the wiring process, that is, when the external wire 18 is wrapped around the wiring screw 2, it is not necessary to contact the original electrical circuit on the pressure plate terminal block. This can avoid affecting the original electrical circuit, ensure equipment operation, and prevent electric shock to operators, thus improving operational safety. Furthermore, in this invention, the outer shell of the wiring fixing device is insulated, further improving operational safety.

[0047] In one embodiment, such as Figure 2-5 As shown, in order not to interfere with the wiring on the original pressure plate terminal block, and at the same time to meet the structural strength and fixing strength of the insulating claw fixing seat 1, the support part in this embodiment includes a number of support claws. Each support claw is spaced apart on the connecting part 110, and the gap between two adjacent support claws forms a wire channel 140.

[0048] It should be noted that in this embodiment, the support part is preferably designed with three support claws, and the connecting part 110 is preferably designed as a disc shape. The three support claws are equidistantly distributed on the connecting part 110. The gap between two adjacent support claws forms a wire channel 140, which is convenient to accommodate the original wires on the terminal. At the same time, in order to avoid electric shock, the support claws are made of insulating material.

[0049] In one embodiment, such as Figure 2-4As shown, in order to increase the connection area between the support claw and the mounting surface 17 around the pressure plate terminal and improve the connection stability, in this embodiment, the support claw includes a vertical support 120 and a horizontal support 130. The vertical support 120 and the horizontal support 130 form an L-shaped structure. The vertical support 120 is connected to the connecting part 110, and the horizontal support 130 is used to connect to the mounting surface 17 around the pressure plate terminal.

[0050] In one embodiment, such as Figure 4 As shown, in order to facilitate the connection between the insulating claw fixing seat 1 and the mounting surface 17 around the pressure plate terminal 14, and to improve the connection stability, the support claw is provided with a strong magnet 9 for adsorbing the terminal fixing device onto the mounting surface 17.

[0051] It should be noted that in this embodiment, the magnetic attraction of the strong magnet 9 is used to facilitate a stable connection between the insulating claw fixing seat 1 and the mounting surface 17 around the terminal block, and to facilitate flexible disassembly. At the same time, the strong magnet 9 is preferably set on the transverse support 130 to improve the wiring stability. Alternatively, adhesive can be directly set on the transverse support 130 to achieve the connection between the insulating claw fixing seat 1 and the mounting surface 17.

[0052] In one embodiment, such as Figure 4 As shown, in order to hide the powerful magnet 9 inside the horizontal support 130 and make the connecting surface of the horizontal support 130 flat, the horizontal support 130 is provided with a mounting groove 8 in this embodiment, and the powerful magnet 9 is installed in the mounting groove 8.

[0053] It should be noted that the mounting groove 8 facilitates the disassembly and replacement of the powerful magnet 9, and also ensures a smooth connection of the transverse support 130, which helps to improve connection stability, while not changing the compression deformation distance of the conductive spring 3.

[0054] In one embodiment, such as Figure 2-4 As shown, in order to further reduce the space occupied by the insulating claw fixing seat 1, and at the same time improve the connection stability by utilizing the abutment between the side wall of the insulating claw fixing seat 1 and the side wall of the terminal insulating base 14, in this embodiment, the side wall of the vertical support member 120 facing the conductive spring 3 is an arc-shaped concave surface. By using the arc-shaped concave surface to match the side wall shape of the terminal insulating base 14, the connection area between the side wall of the insulating claw fixing seat 1 and the side wall of the terminal insulating base 14 is increased. With the help of friction, the connection stability is further improved. At the same time, in order to adapt to different shapes of terminal insulating bases 14, the side wall of the vertical support member 120 facing the conductive spring 3 can be designed with other adaptable shapes.

[0055] In one embodiment, such as Figure 2-4As shown, in order to avoid positional interference between two adjacent terminals, in this embodiment, the connecting part 110 is provided with a clearance part 13. In this embodiment, the clearance part 13 is preferably designed as an arc-shaped structure to reserve installation space for the structure around the terminal, so as to facilitate the smooth installation of the insulating claw fixing seat 1 around the terminal.

[0056] In one embodiment, such as Figure 10-12 As shown, in order to facilitate the turning of the insulating screw cap 4 and save effort, the insulating screw cap 4 in this embodiment is provided with an anti-slip structure 10.

[0057] It should be noted that the anti-slip structure 10 can be a raised anti-slip strip. Several raised anti-slip strips are evenly distributed around the insulating screw cap 4, so that the operator can turn the insulating screw cap 4 by hand, which is convenient for adjusting the installation position. At the same time, the anti-slip structure 10 can also be a recessed anti-slip groove, which has the same design principle as the raised anti-slip strip. Furthermore, in order to ensure the safety of the operator, the insulating screw cap 4 is made of insulating material.

[0058] In one embodiment, such as Figure 6 As shown, in order to facilitate the connection between the wiring screw 2 and the conductive spring 3, and to ensure that the wiring screw 2 and the conductive spring 3 can make full contact and fix, a fixing washer 5 is provided on the wiring screw 2. The end of the conductive spring 3 used to connect with the wiring screw 2 is fixed between the wiring screw 2 and the fixing washer 5. The fixing washer 5 is made of metal material.

[0059] It should be noted that in this embodiment, one end of the wiring screw 2 has a round head, the other end of the wiring screw 2 is a threaded rod, the fixing washer 5 is installed on the wiring screw 2, and one end of the conductive spring 3 is fixed between the round head of the wiring screw 2 and the fixing washer 5.

[0060] In one embodiment, such as Figure 1 As shown, in order to adjust the distance between the insulating screw cap 4 and the insulating claw fixing seat 1, and at the same time to avoid the exposed high-conductivity metal wiring screw 2, in this embodiment, an insulating rubber sleeve 6 is provided between the insulating claw fixing seat 1 and the insulating screw cap 4, and the insulating rubber sleeve 6 is installed on the wiring screw 2.

[0061] It should be noted that, as Figure 13-15 As shown, the insulating rubber sleeve 6 in this embodiment has a cylindrical structure and is elastic. The insulating rubber sleeve 6 is installed on the wiring screw 2 to prevent the wiring screw 2 from being exposed, thereby further improving operational safety. At the same time, it is set between the insulating screw cap 4 and the insulating claw fixing seat 1, which can adjust the distance between the insulating screw cap 4 and the insulating claw fixing seat 1.

[0062] In one embodiment, such as Figure 10-12As shown, in order to facilitate the connection and winding of the external wire 18 with the wiring screw 2, in this embodiment, the insulating screw cap 4 is provided with a first wire hole 11.

[0063] It should be noted that in this embodiment, the insulating screw cap 4 has a cylindrical structure, and the anti-slip structure 10 is provided on the side wall of the insulating screw cap 4. The two ends of the insulating screw cap 4 are an open end and a closed end, respectively. The first wire hole 11 is preferably provided at the closed end of the insulating screw cap 4. In use, the external wire 18 is passed through the first wire hole 11 and wound around the wiring screw 2. While improving the connection stability between the external wire 18 and the wiring screw 2, the first wire hole 11 can prevent the external wire 18 from being damaged due to excessive bending during the wiring process, thus affecting the connection stability. Correspondingly, when the insulating rubber sleeve 6 is installed, the two ends of the insulating rubber sleeve 6 are also an open end and a closed end, respectively. The closed end of the insulating rubber sleeve 6 is provided with a second wire hole 12. The external wire 18 passes through the first wire hole 11 and the second wire hole 12 in sequence and is wound around the wiring screw 2.

[0064] Working principle:

[0065] like Figure 7-9 As shown, a fixing washer 5 is installed on the wiring screw 2, and one end of the conductive spring 3 is fixed between the wiring screw 2 and the fixing washer 5. The wiring screw 2 is installed in the mounting hole 7 of the insulating claw fixing seat 1, so that the conductive spring 3 is located in the support part of the insulating claw fixing seat 1, and the wiring screw 2 protrudes out of the mounting hole 7. The wiring screw 2 and the support part are set opposite to each other. The external wire 18 is passed through the first wire hole 11 on the insulating screw cap 4 and the second wire hole 12 on the insulating rubber sleeve 6 and then wound around the wiring screw 2. The insulating rubber sleeve 6 and the insulating screw cap 4 are installed on the wiring screw 2 in sequence to fix the external wire 18 to the wiring screw 2. When connecting the external wire 18 to the metal screw 15, the insulating claw fixing seat 1 is simply attached to the mounting surface 17 around the terminal insulating base 14 by the strong magnet 9, which can squeeze the conductive spring 3 so that the conductive spring 3 abuts against the metal screw 15, thus completing the connection between the external wire 18 and the metal screw 15.

[0066] This invention eliminates the need for repeated disassembly of the metal screw 15 and installation with the terminal block 16. The external wire 18 can be connected to the metal screw 15 in one step, improving work efficiency. At the same time, this invention can connect the external wire 18 to the metal screw 15 without affecting the original wiring of the pressure plate terminal block, reducing operational risks and improving operational safety.
