Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and more particularly to a device for realizing modular connections. Background Technology

[0002] With the improvement of intelligence, drawer-type switchgear is widely used in the market. Drawer units in drawer-type switchgear generally have three position states: when the drawer unit is in the separated position, both the primary and secondary circuits are disconnected, and communication is interrupted; when the drawer unit is in the test position, the primary circuit is disconnected, and the secondary circuit is connected, and communication is connected; when the drawer unit is in the working position, both the primary and secondary circuits are connected, and communication is connected. While existing connection devices can move the switchgear between the separated, test, and working positions, they are not compatible with different specifications of ferrule combinations. If different ferrule combinations are required, corresponding brackets need to be redesigned, resulting in cost waste. Replacing ferrules in existing switchgear requires replacing the brackets simultaneously, making the process cumbersome and inefficient. Furthermore, the connection devices in existing switchgear are relatively large, wasting internal cabinet space. Summary of the Invention

[0003] This invention provides a device for realizing modular connection. This device is used in the drawer unit of a drawer-type switch cabinet and is compatible with modular connectors composed of different specifications and models of ferrules, enabling quick replacement of ferrules and improving work efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A device for enabling modular connection in a drawer unit of a drawer-type switch cabinet, the drawer unit having three position states: detached position, test position, and working position.

[0006] Includes: a first bracket, the first bracket including a first bracket body and a first socket housing mounted on the first bracket body, the first bracket being mounted on the cabinet of the switch cabinet;

[0007] The second bracket includes a second bracket body and a movable component. The second bracket body is mounted on the drawer unit, and the movable component is mounted on the second bracket body and is movable relative to the second bracket body. It also has a second socket housing.

[0008] A floating limit mechanism is provided between the second support body and the movable part, which prevents the movable part from moving relative to the second support body. When the drawer unit moves from the separated position to the working position, the second support body moves together with the drawer unit to reach the test position first. At this time, the movable part is connected to the first support. Then the drawer unit continues to move into the cabinet. The unlocking part on the first support body cooperates with the floating limit mechanism to unlock the movable part, so that the movable part moves together with the first support relative to the second support body and finally reaches the working position.

[0009] Furthermore, the floating limiting mechanism includes stop members disposed on both sides of the second bracket body and second protrusions on both sides of the movable component; one end of the stop member is pivotally mounted on the second bracket body, and the other free end is provided with a first protrusion. When the drawer unit is in the test position, a floating stroke is provided between the first protrusion and the second protrusion to achieve floating limiting.

[0010] Furthermore, the floating stroke between the first protrusion and the second protrusion is ≤4mm.

[0011] Furthermore, the first support body is provided with an unlocking component, the free end of which is configured as an inverted triangular structure. By pushing open the first protrusion with the unlocking component, the stop can be pivotally rotated to unlock the movable component, thereby enabling the movable component to continue moving relative to the second support body.

[0012] Furthermore, guide rods are provided on both sides of the first socket housing, and guide holes that cooperate with the guide rods are provided on both sides of the second socket housing.

[0013] Furthermore, the first socket housing is provided with a first slot for installing a first ferrule; the second socket housing is also provided with a second slot for installing a second ferrule; the first ferrule and the second ferrule are plugged together to form a modular connector.

[0014] Furthermore, the modular connectors are two or more, and the ferrules between each pair of modular connectors can be configured with different specifications and models.

[0015] Furthermore, the second bracket body is provided with sliding grooves on both sides without stoppers, and the movable part is provided with sliding pieces that match the sliding grooves. When the movable part is unlocked, as the drawer unit moves toward the cabinet, the sliding pieces slide and advance in the sliding grooves so that the drawer unit reaches the working position.

[0016] Furthermore, the movable component is provided with guides on both sides inside the second support body, and the end of the second support body is provided with guide holes that cooperate with the guides, and a spring is sleeved on the guide.

[0017] Furthermore, guide portions are provided on both sides of the second bracket body, and a bent portion is provided on the side of the guide portion away from the stop member. The guide portion and the bent portion cooperate with each other to guide the unlocking member to unlock the floating limit mechanism.

[0018] Furthermore, a return spring is also provided at one end of the stop member fixed to the second bracket body.

[0019] The beneficial effects of this invention are:

[0020] This invention provides a device for modular connection in a drawer unit of a drawer-type switchgear. By setting a floating limiting mechanism between the second support body and the movable part, it enables modular connectors compatible with different specifications and models of ferrules, ensuring conductivity in both the test and working positions even when the height, thickness, and other specifications of the modular connectors are inconsistent. This invention enables rapid assembly, replacement, and installation of modular connectors of different specifications and models, greatly improving work efficiency. The floating limiting mechanism of this invention has a compact structure and a miniaturized design, effectively saving cabinet space and reducing production costs. Attached Figure Description

[0035] Reference Figures 1 to 4This invention relates to a device for implementing a modular connector, comprising a first bracket 1 and a second bracket 2. The first bracket 1 includes a first bracket body 10 and a first socket housing 11 mounted on the first bracket body 10. The first socket housing 11 is fitted with a first ferrule 12 of the modular connector. The mounting surface of the first bracket body 10 has multiple first mounting holes 14. Screws pass through the first mounting holes 14 to fix the first bracket body 10 to the cabinet of a switchgear. The mounting surface of the first bracket body 10 has a square hole for accommodating the first socket housing 11. A first slot 111 of the first socket housing 11 passes through this square hole, and screws pass through a third mounting hole 15 to fix the first socket housing 11 to the side facing away from the mounting surface of the first bracket body 10. The first ferrule 12 is installed in the first slot 111. First spring arms 121 are provided on both sides of the first ferrule 12, and the first spring arms 121 engage with the first slot 111 to fix the first ferrule 12. A guide rod 112 is provided on the side of the first socket housing 11 facing away from the mounting surface of the first bracket body 10.

[0036] The second bracket 2 is fixedly installed in the drawer unit and can move together with the drawer unit. The second bracket 2 includes a second bracket body 20 and a movable component 21, which can move relative to the second bracket body 20. Specifically, a second mounting hole 209 is provided on one side of the second bracket body 20. The second bracket body 20 is fixedly installed to the side wall of the drawer unit by screws passing through the second mounting hole 209. The side of the second bracket body 20 with the second mounting hole 209 and the opposite side are provided with slide grooves 203. The movable component 21 has outwardly extending slide pieces 212 on both sides. The slide pieces 212 and the slide grooves 203 form a sliding pair. In this invention, the slide pieces 212 and the slide grooves 203 form four sets of sliding pairs. The bottom of the second support body 20 is provided with a guide hole 204. The movable part 21 is provided with a guide 213 that matches the position of the guide hole 204, facing the interior of the second support body 20. A compression spring 214 is sleeved on the guide 213. One end of the guide 213 is fixed to the mounting plate of the movable part 21, and the other end passes through the guide hole 204 with the extension and retraction of the compression spring 214, and can move repeatedly within the guide hole 204.

[0037] like Figure 1 and Figure 4The movable component 21 has a square hole on its mounting surface to accommodate the second socket housing 22. The second slot 221 of the second socket housing 22 passes through this square hole, and a screw passes through the fourth mounting hole 210 to fix the second socket housing 22 onto the mounting surface of the movable component 21. The second insert 23 is installed in the second slot 221. Second spring arms 231 are provided on both sides of the second insert 23, and the second spring arms 231 engage with the second slot 221 to fix the second insert 23. The second socket housing 22 has a guide hole 222 corresponding to the guide rod 112 in the first socket housing 11.

[0038] like Figure 3 As shown, unlocking components 13 are provided on both sides of the first bracket body 10, and the free end of the unlocking component 13 is configured as an inverted triangular structure. Figure 4 As shown, a floating limiting mechanism is provided between the second support body 20 and the movable part 21. The floating limiting mechanism includes a stop 201 provided on both sides of the second support body 20 and a second protrusion 211 provided on both sides of the movable part 21. One end of the stop 201 is pivotally mounted on the second support body 20, and a first protrusion 202 is provided at the free end. The extension direction of the free end of the first protrusion 202 is perpendicular to the extension direction of the free end of the second protrusion 211. A floating stroke of 0-4mm is provided between the first protrusion (202) and the second protrusion (211) to achieve floating limiting.

[0039] The following will describe in detail how the device of the present invention achieves floating limit.

[0040] In one embodiment of the present invention, see Figures 5 to 7 This provides an application scenario that can accommodate two modular connectors of the same specifications, meaning that both modular connectors are formed by mating the first ferrule 12 and the second ferrule 23 of the same specifications. Figure 7 It can be seen that when the entire device is in the test position, the first protrusion 202 and the second protrusion 211 in the floating limit mechanism do not directly abut against each other, and there is a certain floating space between them. The maximum floating stroke of the second protrusion 211 in this floating space is 4mm.

[0041] In another embodiment of the invention, see Figures 8 to 10 It provides application scenarios for two different specifications and models of modular connectors. For example, one modular connector is formed by interlocking communication ferrules, and the other modular connector is formed by interlocking power ferrules, but it is not limited to this combination. Figure 10 It can be seen that when the entire device is in the test position, the first protrusion 202 and the second protrusion 211 in the floating limit mechanism directly abut against each other, and the floating stroke of the second protrusion 211 is 0mm.

[0042] It is understood that, in other embodiments of the present invention, the floating stroke of the floating limit mechanism can be adaptively adjusted according to the specifications of the ferrule, and can be 3mm, 2mm or 1mm.

[0043] However, it should be understood that the present invention can reasonably design the number of modular connectors that can be accommodated according to the spatial size requirements of the drawer unit, thereby meeting different needs.

[0044] Working principle of the device of the present invention:

[0045] When the drawer unit is in the separated position, the movable part 21 of the second bracket 2 is locked on the second bracket body 20 by the floating limit mechanism. Thus, when the second bracket 2 moves towards the cabinet along with the drawer, the guide rod 112 and the guide hole 222 cooperate to guide the second bracket 2 to move relative to the first bracket 1, realizing the function of one-time guidance and position correction. During this process, the first insert 12 and the second insert 23 are flexibly inserted into the position to achieve connection and fixation. At this time, the communication device reaches the test position, and the movable part 21 in the second bracket 2 forms a reliable connection with the first bracket 1. At this time, the second protrusion 211 in the floating limit mechanism can float relative to the first protrusion 202 and abut against it to achieve floating limit, preventing the movable part 21 from moving relative to the second bracket body 20. At the same time, the free end of the unlocking part 13 is exactly against one side of the first protrusion 202.

[0046] As the drawer unit continues to move into the cabinet, the unlocking member 13 on the first support body 10 cooperates with the floating limit mechanism to unlock the movable part 21. Specifically, the unlocking member 13 pushes open the first protrusion 202, allowing the stop member 201 to pivotally rotate and unlock the movable part 21. The slide 212 slides and advances within the slide groove 203, compressing the compression spring 214. The guide member 213 passes through the guide hole 204 and moves in the opposite direction, enabling the movable part 21 to drive the first support 1 to continue moving relative to the second support body 20, ultimately reaching the working position.

[0047] Specifically, as an embodiment of the present invention, when the device contains two modular connectors of the same specifications and models, the second protrusion 211 has a floating stroke of 4mm relative to the first protrusion 202. When the drawer unit is in the test position, the first protrusion 202 and the second protrusion 211 do not contact each other. As the drawer unit moves further into the cabinet, the movable part first drives the second protrusion 211 to move towards the first protrusion 202 until the second protrusion 211 and the first protrusion 202 are misaligned and abutted to achieve a limit. At the same time, the free end of the unlocking part 13 is exactly against one side of the first protrusion 202. Then, the unlocking part 13 cooperates with the floating limit mechanism to unlock the movable part 21, so that the movable part 21 drives the first bracket 1 to continue to move relative to the second bracket body 20, and finally reaches the working position.

[0048] In another embodiment of the present invention, when the device contains two modular connectors of different specifications and models, the second protrusion 211 directly abuts against the first protrusion 202 to achieve a limit, and at the same time, the free end of the unlocking member 13 abuts against one side of the first protrusion 202. As the drawer unit moves further into the cabinet, the unlocking member 13 cooperates with the floating limit mechanism to unlock the movable part 21, so that the movable part 21 drives the first bracket 1 to continue to move relative to the second bracket body 20, and finally reaches the working position.

[0049] By adjusting the limiting gap of the floating limiting mechanism, this invention not only solves the problem that existing connection devices cannot be compatible with modular connectors of different specifications and models at the same time, but also ensures that the ferrules of multiple modular connectors can form reliable conduction in the test position and the working position. It can be understood that the modular connector here is compatible with ferrule combinations of the same specification and model as well as ferrule combinations of different specifications and models.

[0050] The connecting device of this invention can be reduced in size to 96mm*112mm*40mm, while the size of existing connecting devices is 111mm*123mm*53mm. This shows that the size of the connecting device of this invention can be reduced to 60% of that of existing connecting devices. Because existing connecting devices often use multiple parts riveted together to form a support, more bending sections are usually required at the bottom and other stress-bearing parts to meet strength requirements, thus failing to meet the needs of miniaturization. However, the second support body of the connecting device of this invention is a single piece formed by bending, eliminating the need for additional riveting parts while meeting strength requirements. This reduces the number of parts, achieves miniaturization, and effectively saves cabinet space. Furthermore, the connecting device of this invention also enables quick replacement of the ferrule; simply disengaging the ferrule's spring arm from the slot in the socket housing completes the replacement of the modular connector, allowing for rapid combination of different modular connectors.

[0051] In another embodiment of the present invention, a guide portion 205 is provided on the side of the second bracket body 20 where the stop member 201 is located, and a bent portion 206 is provided on the side of the guide portion 205 away from the stop member 201. The guide portion 205 and the bent portion 206 cooperate to guide the unlocking member 13 to unlock the floating limit mechanism. A return spring 207 is also provided at one end of the stop member 201 fixed to the second bracket body 20. Third protrusions 208 are provided on both sides of the second bracket body 20. One end of the return spring 207 is fixed to the third protrusion 208, and the other end is fixed to the stop member 201. The present invention does not limit the fixing method of the return spring. The guide portion 205 and the bent portion 206 provide secondary guiding and position correction functions for the unlocking member 13, making the force on the ferrule more stable and uniform, and effectively preventing the ferrule from being damaged due to uneven force.

[0052] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
