Description

Technical Field

[0001] The present invention relates to the technical field of high and low voltage power distribution cabinets, and in particular to a high and low voltage power distribution cabinet wiring assembly and a high and low voltage power distribution cabinet. Background Art

[0002] In the field of electrical design, terminal blocks are commonly used connection components, which are used to connect and conduct wires and electronic components. One end of the wire in the cable is connected to the terminal block; at this time, the wire in the cable is conductively connected to the electronic component. As the name suggests, high and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Terminal blocks are an accessory product used to achieve power connection. The terminal blocks are installed on the base and then installed with the distribution cabinet.

[0003] In a mobile mounting base for high and low voltage distribution cabinet terminal blocks that is easy to install with application number CN202321302859.9, a convenient moving component is provided, including through holes opened on both sides of the base body, a receiving groove opened in the base body, an extension hole opened on the side of the base body, a first rotating shaft installed in the through hole, a rotating handle installed on the first rotating shaft, a rotating rod installed at the bottom of the first rotating shaft, an extension rod installed on the rotating rod, and a second rotating shaft installed on the extension rod. Through the mutual cooperation of the main structure and the convenient moving structure, the operation steps are simple and efficient, and the movement and disassembly are convenient, which makes it convenient for the base to change its position according to the needs of wire connection, and the installation is firm.

[0004] However, when this type of terminal is used for cable wiring, the terminal block generally adopts screws and base holes to cooperate to fix the conductive sheet of the terminal, and the on-off state of the line is controlled by tightening or loosening the screws. However, once the screws are loosened, they are easy to fall off and lost because there is no limit on the screws. In addition, the conductive sheet of the terminal is also easy to shake after being loosened. When installing the cable end, it is necessary to manually press the conductive sheet to reposition it, then install the cable end, and then tighten the screws. However, when installing the cable connector, it is easy for the conductive sheet to slide and shift due to the insertion of the cable connector, and there is a risk of poor contact after tightening the screws.

[0019] Technical effects and advantages of the present invention:

[0020] 1. The wiring unit on the terminal block of the present invention can ensure the orderliness and independence of cable connection. When installing cables without copper noses, the copper wire inner core is inserted into the cable between the limit ring and the terminal post along the wire groove. The limit ring can have a guiding and bending effect on the copper wire inner core, so that the copper wire inner core moves along the inner wall of the limit ring until it is wrapped around the outer wall of the terminal post. In this way, the cable without copper nose can be naturally sleeved on the terminal post, which improves the convenience of cable wiring. At the same time, it does not affect the contact surface of the cable wiring, and can avoid poor contact when wiring cables without copper noses. At the same time, the terminal post and the guide seat are integrally formed, and the limit ring is fixed to the top of the guide seat, so that the terminal is integrated, avoiding the situation that the conductive sheet slips and dislocates after loosening, and can fundamentally solve the defect of incomplete wiring caused by loosening and sliding of the conductive sheet during cable connector wiring.

[0021] 2. When the pressure plate in the present invention moves downward to pressurize the limit ring, it will first squeeze the pressure sleeve, which can prompt the gas inside the pressure sleeve to be introduced into the second corrugated sleeve through the gas pipe. Therefore, in the process of the pressure plate continuously squeezing the pressure sleeve, the copper nose or the copper wire inner core of the cable can be tightly pressed on the conductive seat to achieve pressurized fixation and self-locking of the cable, thereby completing the wiring operation of the cable, with high safety, ensuring that the cable will not be detached, and preventing poor contact of the cable joints.

[0022] 3. When the present invention needs to inspect and repair the wiring unit, the second electric control valve is opened, and the gas inside the first corrugated sleeve is introduced into the second corrugated sleeve through the air guide tube, causing the second corrugated sleeve to expand, which can produce a pushing effect on the slide plate, so that after the slide plate overcomes the rebound force of the reset spring, it drives the baffle plate, the connecting plate and the slide plate to be synchronously stored in the guide groove, completing the storage of the baffle plate, facilitating the inspection and repair operation of the connection between the cable and the wiring unit, and improving the operating convenience.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0035] Embodiment 1:

[0036] This embodiment provides Figures 1 to 10 A high and low voltage distribution cabinet wiring assembly shown includes multiple groups of terminal blocks 20 with the same structure, which is convenient for adjusting the number of terminal blocks 20 according to actual cable installation needs, and is easy to operate. Each group of terminal blocks 20 includes an insulating base 22, and a linearly arranged wiring port 23 is opened on the insulating base 22. A wire groove 24 corresponding to the wiring port 23 is opened on the insulating base 22, and a wiring unit 30 is fixedly installed in each group of wiring ports 23. The wiring unit 30 is convenient for installing cables with or without copper noses, and the wire groove 24 can complete the storage of cables to ensure the orderliness and independence of the cables.

[0037] See also Figure 3-Figure 5 Each group of wiring units 30 includes a conductive seat 31 fixed at the bottom of the wiring port 23, a terminal post 32 is fixed in the middle of the top of the conductive seat 31, a limiting ring 33 fixed to the top of the conductive seat 31 is arranged on the outer coaxial center line of the terminal post 32, a terminal screw 34 is connected to the internal thread of the terminal post 32, a threaded hole adapted to the terminal screw 34 is provided on the terminal post 32, a pressing plate 35 is rotatably sleeved on the terminal screw 34, the pressing plate 35 is slidably assembled in the wiring port 23, a limiting rib 36 is fixed on the top of the side wall of the wiring port 23, the size of the pressing plate 35 is adapted to the cross-sectional size of the wiring port 23, an annular groove is provided on the outer wall of the wiring screw 34, and the pressing plate 35 is rotatably assembled in the annular groove, and the limiting rib 36 and the pressing plate 35 correspond to each other.

[0038] When wiring, the wiring screw 34 is turned upward to make the wiring screw 34 and the wiring post 32 disengage. At this time, since the pressure plate 35 is slidably assembled in the wiring port 23, it can have a good limiting effect on the wiring screw 34 to prevent the wiring screw 34 from falling off, and the limiting rib 36 is limited above the pressure plate 35, so that the wiring screw 34 will not fall off from the wiring port 23 after loosening from the wiring post 32. At the same time, the verticality of the wiring screw 34 can be ensured, so that the wiring screw 34 can be quickly turned after the cable is installed to complete the cable wiring operation and avoid the situation where the wiring screw 34 does not correspond. Therefore, when installing a cable with a copper nose, it is only necessary to put the copper nose on the wiring post 32 and then tighten the wiring screw 34, which can simultaneously drive the pressure plate 35 to squeeze the limiting ring 33. During the downward movement, the limiting ring 33 can be continuously squeezed, and then the copper nose is squeezed so that the copper nose is tightly installed on the conductive seat 31, thereby improving safety. The cable without a copper nose is installed at the end of the cable so that the inner core of the copper wire is exposed. Then, the cable is inserted between the limit ring 33 and the terminal post 32 along the wire groove 24. During the insertion of the inner core of the copper wire, since the limit ring 33 is annular, it can guide and bend the inner core of the copper wire, so that the inner core of the copper wire moves along the inner wall of the limit ring 33 until it is wrapped around the outer wall of the terminal post 32. In this way, the cable without a copper nose can be naturally sleeved on the terminal post 32, thereby improving the convenience of cable wiring. At the same time, it does not affect the contact surface of the cable wiring, and can avoid poor contact when wiring the cable without a copper nose. At the same time, the terminal post 32 and the conductive seat 31 are integrally formed, and the limit ring 33 is fixed to the top of the conductive seat 31, so that the terminal is integrated, avoiding the situation that the conductive sheet slips and dislocates after loosening, and can fundamentally solve the defect of incomplete wiring caused by loosening and sliding of the conductive sheet during cable connector wiring.

[0039] It is worth mentioning that please refer to Figure 8 The limiting ring 33 includes an annular seat 331 fixed to the top of the conductive seat 31. The annular seat 331 is used to limit the cable and realize the conductive operation at the same time. A wire notch 333 corresponding to the wire groove 24 is opened on the rear side of the annular seat 331 to facilitate the guiding of the cable. A pressurizing sleeve 332 is fixed on the top of the annular seat 331. An inwardly concave arc groove 334 is opened at the bottom of the inner side wall of the annular seat 331, and the arc groove 334 corresponds to the terminal 32. The height of the annular seat 331 is lower than the terminal 32, and the height of the pressurizing sleeve 332 is higher than the terminal 32.

[0040] When installing a cable without a copper nose, the copper wire core of the cable is inserted into the limit ring 33 and the terminal 32 along the wire groove 24 and the wire notch 333, and during the insertion of the copper wire core, the copper wire core and the arc groove 334 fit together, and the arc groove 334 can guide and bend the copper wire core, so that the copper wire core moves along the arc groove 334 until it is wrapped around the wire notch 333. In this way, the cable without a copper nose can be naturally put on the terminal 32, thereby improving the convenience of cable wiring.

[0041] See also Figure 7 and Fig.10 The left, front and right side walls of the terminal 32 are all slidably assembled with limiters 50. The terminal 32 includes a receiving groove 51 arranged on its outer side wall corresponding to the limiter 50. The limiter 50 is fixed with a second corrugated sleeve 52 on the side of the receiving groove 51 away from the opening. The other end of the second corrugated sleeve 52 is fixed with a slide seat 53, and the slide seat 53 is slidably assembled in the receiving groove 51. The pressurization sleeve 332 and the second corrugated sleeve 52 are both pressure-bearing air bags. The pressurization sleeve 332 is connected to the second corrugated sleeve 52 through an air supply pipe, and a first electric-controlled valve is fixedly assembled on the air supply pipe.

[0042] After the cable is positioned and installed, start tightening the wiring screws 34. When the wiring screws 34 drive the pressure plate 35 to move downward to pressurize the limit ring 33, the pressurization sleeve 332 will be squeezed first. At this time, the first electric control valve is opened, which can prompt the gas inside the pressurization sleeve 332 to be introduced into the second corrugated sleeve 52 through the gas pipe. Therefore, in the process of the pressure plate 35 continuously squeezing the pressurization sleeve 332, the copper nose or the copper wire core of the cable can be tightly pressed on the conductive seat 31 to achieve pressurized fixation, thereby completing the wiring operation of the cable, which has high safety and ensures that the cable will not be detached, while preventing poor contact of the cable joints.

[0043] See also Fig.10 The two sets of flexible clamping ridges 55 are fixed to the top and bottom of the clamping seat 54. The clamping seat 54 is an arc-shaped seat. Two sets of flexible clamping ridges 55 are symmetrically mounted on the upper and lower sides of the clamping seat 54, and arc-shaped clamping grooves are opened on the side walls of the two sets of flexible clamping ridges 55 on the opposite sides. When gas is introduced into the second corrugated sleeve 52, the second corrugated sleeve 52 expands, thereby generating a thrust on the sliding seat 53, pushing the clamping seat 54 to extend out of the receiving groove 51. When the two sets of flexible clamping ridges 55 extend out of the receiving groove 51, the flexible clamping ridges 55 flip outward and reset, so that the clamping seat 54 and the two sets of flexible clamping ridges 55 are used to pressurize and limit the inner side of the copper nose, thereby preventing the copper nose from sliding on the outside of the terminal 32, improving the centering of the copper nose sleeve on the outside of the terminal 32, improving the tightness of the cable installation, and preventing the cable from detaching.

[0044] It should also be noted that when the copper wire core of the cable is sleeved on the outside of the terminal 32, the extended clamping seat 54 and the two sets of flexible clamping ridges 55 will squeeze the copper wire core to prevent the copper wire core from loosening. Therefore, the limiting ring 33 cooperates with the squeezing effect of the clamping seat 54 and the two sets of flexible clamping ridges 55 to make the copper wire core tightly fit on the inner wall of the limiting ring 33, thereby realizing self-locking of the cable. In addition, the downward pressure of the pressure plate 35 can improve the tightness of the cable installation and prevent the cable from detaching.

[0045] Embodiment 2:

[0046] This embodiment provides Figures 1 to 10 The high and low voltage distribution cabinet wiring assembly shown includes the technical features disclosed in Example 1, please refer to Figure 6 and Fig. 9 Guide grooves 25 are provided on the left and right side walls of the wire groove 24, and each group of guide grooves 25 is equipped with a protective member 40, and two groups of protective members 40 are arranged opposite to each other and encapsulated in the wire groove 24, and each group of protective members 40 is flush with the pressure plate 35. The protective member 40 can cover the cables stored in the wire groove 24 to prevent dust accumulation, and at the same time prevent foreign objects from being stuck on the wiring unit 30 and affecting the contact of the cable during wiring.

[0047] For details, please refer to: Figure 6 and Fig. 9 Each group of protective members 40 includes a slide plate 41 slidably assembled inside the guide groove 25, and the side of the guide groove 25 away from the opening and the slide plate 41 are connected by a return spring 43, and the other side of the slide plate 41 and the inner wall of the guide groove 25 are connected and assembled with a first corrugated sleeve 44, and the return spring 43 and the second corrugated sleeve 52 correspond to each other one by one, and the number is set according to actual installation needs, and a connecting plate 42 is fixed in the middle of the outer wall of the slide plate 41, and the connecting plate 42 extends out of the guide groove 25 and is hingedly assembled with a baffle 45 through a hinge spring, the size of the guide groove 25 matches the slide plate 41, and a guide channel matching the thickness of the connecting plate 42 is opened near the opening of the guide groove 25, and the thickness of the connecting plate 42 is the same as that of the baffle 45, and the connecting plate 42 and the baffle 45 are both lightweight insulating plastic plates.

[0048] The first corrugated sleeve 44 is a strip-type pressure-bearing air bag, and the first corrugated sleeve 44 is connected to the second corrugated sleeve 52 through an air duct, and a second electrically controlled valve is fixedly installed on the air duct. When the cable passes through the wire groove 24, the baffle 45 in the protective member 40 is encapsulated in the wire groove 24. When the cable is connected to the wiring unit 30, the baffle 45 is flush with the pressure plate 35. In this way, the baffle 45 and the pressure plate 35 are used to shield the connection between the cable connector and the wiring unit 30, thereby improving the dustproof effect.

[0049] After a period of actual use, when the wiring unit 30 needs to be inspected and repaired, the second electrically controlled valve is opened, and the gas inside the second bellows sleeve 52 is introduced into the first bellows sleeve 44 through the air duct, causing the first bellows sleeve 44 to expand, which can produce a pushing effect on the slide plate 41, so that the slide plate 41 overcomes the rebound force of the reset spring 43, and drives the baffle plate 45, the connecting plate 42 and the slide plate 41 to be synchronously stored in the guide groove 25, completing the storage of the baffle plate 45, facilitating the inspection and repair operations on the connection between the cable and the wiring unit 30, and improving the operating convenience.

[0052] It should be noted that the number of indicator lights 13 is the same as the number of wiring units 30, and a single group of indicator lights 13 corresponds to a single group of wiring units 30. When in use, when the wiring unit 30 is in a powered-on state, the second electrically controlled valve is closed, so that the protective member 40 is encapsulated in the wire groove 24, and the wiring unit 30 and the cable are dust-proofed. When the wiring unit 30 is powered off, the second electrically controlled valve is opened synchronously, and the gas inside the second corrugated sleeve 52 is introduced into the first corrugated sleeve 44 through the air guide pipe, pushing the protective member 40 to shrink inside the guide groove 25, thereby The wiring unit 30 is then inspected and repaired. At the same time, the indicator light 13 on the cabinet door 12 corresponding to the group of wiring units 30 lights up, reminding the staff to inspect the wiring unit 30 on the terminal block 20 that is in the power-off state. When the electrical equipment connected by the cable does not work and the wiring unit 30 is in the power-on state, it indicates that the cable is not conductive and the cable corresponding to the electrical equipment needs to be replaced.
