Description

Technical Field

[0001] This utility model relates to the field of power accessory technology, and in particular to a modular quick-connect box. Background Technology

[0002] In electrical equipment such as distribution cabinets, it is usually necessary to distribute the power from the upstream circuit breaker (such as the main switch) to multiple downstream branch circuit breakers or electrical equipment through busbars. The traditional connection method is to directly fix the bare busbar, which has been cut to the correct length, into the cabinet and use insulators for support and isolation.

[0003] This traditional busbar connection method presents significant safety hazards and inconveniences: First, exposed live parts of the busbars are easily touched by workers during installation, commissioning, or subsequent maintenance, potentially causing electric shock. Second, accidental contact between exposed busbars due to tools, wire ends, or other foreign objects can easily lead to phase-to-phase short circuits, generating electric arcs and causing equipment damage or even fires. Furthermore, the traditional method lacks flexibility; if the power distribution scheme needs to be changed or expanded, the busbars must be remeasured, cut, and reinstalled, resulting in cumbersome construction, long cycles, and difficulty in achieving standardized production.

[0004] This has resulted in a lack of standardized connection components in power distribution systems that require compactness, flexibility, and safety. Utility Model Content

[0013] Preferably, the locking component includes a matching bolt and nut, the connector access portion is provided with a bolt hole for the bolt to pass through, and the nut is engaged in a nut slot inside the insulating shell.

[0014] Preferably, the insulating shell includes a base and a cover that are fixed together; the left end and / or the right end of the insulating shell forms an insertion hole between the base and the cover for the tap to pass through.

[0015] Preferably, the base is provided with a positioning post, and the main conductive busbar is provided with a positioning hole at a corresponding position that interlocks with the positioning post.

[0016] Preferably, a baffle is installed on the left side wall and / or right side wall of the insulating shell, and the front and rear edges of the baffle are respectively provided with a first opening and a second opening.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] The modular quick-connect box structure in this embodiment of the utility model is as follows: Figures 1 to 6As shown, it includes an insulating shell 1, and a main conductive bus 2 and a tap conductive bus 3 disposed within the insulating shell 1; the upper end of the main conductive bus 2 is provided with a main connector 21 extending upward from the insulating shell 1; the lower end of the main conductive bus 2 is provided with a connector access portion 22, the position of the connector access portion 22 on the insulating shell 1 corresponding to the main connector 21, so that when at least two junction boxes are spliced ​​vertically, the connector access portion 22 of the upper junction box can be aligned and connected with the main connector 21 of the lower junction box (see reference). Figure 7 The tap conductor 3 is electrically connected to the main conductor 2 and has a tap 31 that extends at least laterally out of the insulating shell 1. The tap 31 extends outward from the left end and / or right end of the insulating shell 1 (the tap conductor 3 can be set on the left, right, or both sides of the insulating shell 1 according to actual needs). During installation and use, the tap 31 can be connected to the circuit breaker installed on the corresponding side of the junction box. This utility model encapsulates the main conductor 2 and the tap conductor 3 through the insulating shell 1, eliminating the risk of electric shock and short circuit caused by exposed busbars in the background technology. Its modular design allows multiple junction boxes to be quickly expanded by splicing them up and down. The connector access part 22 of the main conductor 2 corresponds to the position of the main connector 21, realizing the alignment connection, simplifying the installation process, solving the drawbacks of traditional busbars that require custom cutting and are cumbersome to install, and providing a safe, flexible and standardized connection solution for the power distribution system.

[0030] See Figure 2 and Figure 4 As shown, the lower front of the insulating shell 1 is provided with a recessed portion 10, and the connector access portion 22 is provided in the recessed portion 10. By providing the recessed portion 10 at the lower front of the insulating shell 1 and accommodating the connector access portion 22 therein, the corresponding components of the connector access portion 22 can be installed and necessary locking operations can be performed.

[0031] See Figure 1 The lower end of the insulating shell 1 is provided with a cover 5 at the recess 10. The cover 5 covers the front of the connector access part 22, which can enhance the protection effect and enhance the safety of use.

[0032] See Figure 2 and 4 The connector access part 22 has an interface 23 suitable for the insertion of the main connector 21. Thus, when the junction boxes are spliced ​​together, the main connector 21 on the next junction box is inserted into the interface 23 on the connector access part 22 on the previous junction box, and electrical conduction is achieved by contacting the side wall of the interface 23. The connection is fast and reliable.

[0033] Continue reading Figure 2 and Figure 4The connector access portion 22 includes a first clip 24 and a second clip 25 fixed and spaced apart from the main conductive busbar 2. The interface 23 is formed between the first clip 24 and the second clip 25. This arrangement allows the main connector 21 to simultaneously contact both clips 24 and 25 on both sides after insertion into the interface, thereby increasing the contact area and ensuring electrical conductivity. The first clip 24 and the second clip 25 can be fixedly connected to the main conductive busbar 2 by riveting, welding, or other methods.

[0034] like Figure 4 As shown, in this embodiment, the connector access portion 22 is further provided with a locking member 4. The locking member 4 acts on the clamping piece 1 24 and / or clamping piece 25 to reduce the size of the interface 23. In actual use, after the main connector 21 is inserted into the interface 23, the clamping piece 1 24 and clamping piece 25 effectively clamp the inserted main connector 21 when the locking member 4 is tightened, thereby ensuring that the electrical connection remains reliable and stable during long-term use. Preferably, the locking member 4 includes a matching bolt 41, nut 42 and washer. The connector access portion 22 is provided with a bolt 41 through hole for the bolt 41 to pass through. The nut 42 is inserted into the nut slot 11 in the insulating shell 1. Inserting the nut 42 into the nut slot 11 can effectively prevent the nut 42 from rotating when the bolt 41 is tightened. After the main connector 21 is connected to the connector access portion 22, the bolt 41 is tightened, thereby pressing the main connector 21 and the connector access portion 22 together.

[0035] In some embodiments, the insulating shell 1 includes a base 12 and a cover 13 that are fixed together. The insulating shell 1 adopts a split structure in which the base 12 and the cover 13 are fixed together, which facilitates the assembly of the internal conductive busbars (including the main conductive busbar 2 and the tap conductive busbar 3). At the same time, the left end and / or the right end of the insulating shell 1 forms an insertion hole 14 between the base 12 and the cover 13 for the tap 31 to pass through. Preferably, the base 12 is provided with a positioning post 121, and the main conductive busbar 2 is provided with a positioning hole 26 at a corresponding position, so that the positioning post 121 and the positioning hole 26 are used to strengthen the positioning of the main conductive busbar 2 and prevent it from shaking.

[0036] See Figure 5 and Figure 6As shown, a baffle 15 is installed on the left side wall and / or right side wall of the insulating shell 1. The front and rear edges of the baffle 15 are respectively provided with a first opening 151 and a second opening 152. The baffle 15 is configured to be installed on the insulating shell 1 in different orientations, so that the first opening 151 or the second opening 152 serves as a through hole 14 to accommodate taps 31 of different shapes and widths. By setting the baffle 15 to be installed in different orientations, the requirement of one component to accommodate taps 31 of different shapes is met. The first opening 151 and the second opening 152 can respectively accommodate taps 31 of different shapes and widths, such as round pins and flat pins (of different widths), improving the application flexibility and versatility of the product and reducing production costs. Furthermore, a bayonet can be provided on the left side wall and / or right side wall of the insulating shell 1, and the baffle 15 is installed by engaging with the edge of the bayonet.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
