Description

Technical Field

[0001] This utility model relates to the field of electrical connection technology, specifically to LDB branch terminals. Background Technology

[0002] In the field of electrical connections, branch terminals, as key components for realizing the split connection between the main cable and multiple branch lines, are widely used in various circuit systems.

[0003] Currently, branch terminals on the market come in various structural forms. Common ones consist of an insulating base, a wiring frame, and a protective cover. The wiring frame includes wire clamps, screws, nuts, and a support frame. By combining wire clamps of different shapes, double-layer wiring can be achieved, resulting in a continuous "T-shaped" connection of the trunk line. Others use a U-shaped base plate with a T-shaped rotating component. The T-shaped rotating component connects to an upper pressure plate, and the U-shaped base plate has a lower pressure plate. Wiring is achieved through the cooperation of these two components.

[0004] However, these existing branch terminals have several drawbacks in practical use. Firstly, most branch terminals lack a structure that intuitively distinguishes the phase sequence of electrical components, making it difficult for workers to quickly identify different phase sequences during wiring. This can easily lead to incorrect wiring, affecting the normal operation of the circuit and potentially causing safety accidents. Secondly, the wire sequence marking function is insufficient, failing to provide personalized markings based on the actual needs of the client. In scenarios with multiple branch connections, finding the correct wire sequence is difficult, significantly reducing wiring efficiency and increasing the difficulty of later maintenance. Thirdly, the existing branch terminals are structurally unsuitable for flexible splicing to accommodate different numbers of outgoing lines, and their installation methods are not flexible enough to adapt well to various installation environments. For example, some branch terminals only support a single installation method, or their installation structure is unstable, making them prone to detachment.

[0005] Therefore, it is necessary to study LDB branch terminals. Utility Model Content

[0006] To address the problems mentioned in the background art, the purpose of this utility model is to provide an LDB branch terminal, which has the advantages of easy and intuitive differentiation of power phase sequence and wire sequence, convenient splicing to increase the number of outgoing lines, and flexible installation method. It solves the problems of existing branch terminals having unintuitive differentiation of phase sequence and wire sequence, low wiring efficiency, difficulty in flexible splicing to adapt to different outgoing line requirements, and insufficient installation method.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an LDB branch terminal, comprising a terminal housing, a cable inlet hole at the center of one end of the terminal housing, at least six evenly arranged outlet holes at the other end of the terminal housing, a spare hole for bridging cable installation on one side of the terminal housing, an installation opening at the top of the terminal housing, and the installation opening communicating with the cable inlet hole, outlet hole and spare hole respectively, a connector being snapped into the interior of the installation opening, a cover being snapped into the top of the installation opening, a snap-fit ​​groove being opened at the top of the cover, a marking strip being snapped into the top of the snap-fit ​​groove, a snap-fit ​​hole being opened at the top of the cover, a color marking block being snapped into the top of the snap-fit ​​hole, a slot and a limiting groove being opened on one side of the terminal housing, and a buckle and a limiting point adapted to the slot and the limiting groove being fixedly connected to the other side of the terminal housing, and the buckle and the limiting point are used in conjunction with the slot and the limiting groove respectively.

[0008] As a preferred embodiment of this utility model, the bottom of the terminal housing is symmetrically fixedly connected with a mounting base, the surface of the mounting base is provided with screw holes, and the bottom of the terminal housing is fixedly connected with an elastic locking foot that can be connected to an external guide rail.

[0009] As a preferred embodiment of the present invention, one side of the connector is provided with a main connector and a spare connector, and the main connector and the spare connector are respectively provided in correspondence with the cable inlet hole and the spare hole. The other end of the connector is provided with at least six evenly arranged outlet holes, and the outlet holes are respectively in one-to-one correspondence with the outlet holes.

[0010] As a preferred embodiment of this utility model, the top of the connector is provided with several wire pressing ports, and the several wire pressing ports are respectively connected to the main connector, the spare connector and the outlet connector, and the internal thread of the wire pressing port is connected with a wire pressing screw.

[0011] As a preferred embodiment of the present invention, a fixing groove is provided on the top of one side of the terminal housing, a fixing card is fixedly connected to the bottom of the cover, and the fixing card is engaged with the fixing groove; an auxiliary groove is provided on the top of the other side of the terminal housing, an auxiliary post is fixedly connected to the bottom of the cover, and the auxiliary post is engaged with the auxiliary groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model allows customers to intuitively distinguish the phase sequence of electricity by setting color marking blocks on the top of the cover. At the same time, the cover is provided with marking strip mounting holes, and the marking strips can be printed with the customer's required numbers, which facilitates the customer's wiring and wire sequence lookup. This solves the problems of the existing branch terminal phase sequence and wire sequence not being intuitive to distinguish and the wiring efficiency being low.

[0015] 2. This utility model achieves splicing between multiple terminals by designing and installing slots, limiting slots, and matching buckles and limiting points on the side of the terminal housing. The inlet end is provided with a main cable inlet hole and a spare hole.

A snap-fit ​​groove is provided on the top of the cover 7, and the top of the snap-fit ​​groove... A marking strip 8 is attached, on which the required numbers can be printed for easy wiring. The top of the cover 7 has a snap-fit ​​hole, and a color marking block 9 is snapped onto the top of the snap-fit ​​hole. The color marking block 9 is used to visually distinguish the power phase sequence. One side of the terminal housing 1 has a slot 10 and a limiting groove 11. The other side of the terminal housing 1 is fixedly connected with a buckle 12 and a limiting point 13 that are adapted to the slot 10 and the limiting groove 11. The buckle 12 and the limiting point 13 are used in conjunction with the slot 10 and the limiting groove 11, respectively. Through the snap-fit ​​engagement of the buckle 12 with the slot 10 and the limiting point 13 with the limiting groove 11, two independent terminal housings 1 can be spliced ​​together.

[0023] refer to Figure 3 The bottom of the terminal housing 1 is symmetrically fixedly connected with a mounting base, and the surface of the mounting base is provided with screw holes 14. The bottom of the terminal housing 1 is fixedly connected with an elastic locking foot 15 that can be connected to an external guide rail.

[0024] As a technical optimization of this utility model, by setting screw holes 14 and elastic clips 15, two installation methods are provided. The client can fix the terminal on the plane by passing screws through screw holes 14, or directly use elastic clips 15 to quickly connect with the peripheral guide rail, which enhances the flexibility and adaptability of installation.

[0025] refer to Figure 4 One side of the connector 6 is provided with a main connector and a spare connector, and the main connector and the spare connector are respectively provided with the cable inlet hole 2 and the spare hole 4. The other end of the connector 6 is provided with at least six evenly arranged outlets, and the outlets are respectively provided with the outlet holes 3.

[0026] As a technical optimization of this utility model, the structural design of corresponding main wiring port with cable inlet hole 2, spare port with spare hole 4, and outlet port with outlet hole 3 ensures that the paths of cable inlet, bridging connection (spare) and branch line outlet are clear, avoids wiring confusion, and improves wiring efficiency.

This facilitates the quick installation and removal of the cover 7 (facilitating the later maintenance of the wiring component 6) and prevents the cover 7 from accidentally falling off during use, thus protecting the internal wiring structure.

[0031] refer to Figure 1 The inner wall of the spare hole 4 is fixedly connected with a detachable baffle.

[0032] As a technical optimization of this utility model, by setting a detachable baffle, when the spare hole 4 is not needed for bridging wire series connection, the baffle can close the spare hole 4 to prevent dust and debris from entering the interior and affecting the circuit; when series connection is required, the baffle can be removed to install the bridging wire, thus taking into account both protection and functionality.

[0033] The working principle and usage process of this utility model: The working principle of this LDB branch terminal is that the terminal housing 1 is used as the overall support structure. The main cable is connected to the main terminal of the connector 6 through the cable inlet hole 2. After being distributed by the connector 6, the current is transmitted to each branch through the outlet corresponding to the outlet hole 3. When multiple terminals are connected in series, the spare hole 4 is used in conjunction with the spare port of the connector 6 through the bridging wire to realize the current transmission and increase the number of outlets (e.g., a product with 6 outlets can be spliced ​​to reach 12 outlets). The removable baffle on the inner wall of the spare hole 4 can close the hole to prevent foreign objects from entering when not in use. The color marking block 9 on the cover 7 is used to... The snap-fit ​​holes are used to visually distinguish the phase sequence of the power supply. The marking strip 8 is installed through the snap-fit ​​groove of the cover 7 and can be printed with numbers to facilitate the identification of the wire sequence. The snap-fit ​​groove 10 and the limiting groove 11 on one side of the terminal housing 1 cooperate with the snap-fit ​​12 and the limiting point 13 on the other side to realize the splicing and fixing of multiple terminals. The elastic snap-fit ​​feet 15 at the bottom can be connected to the external guide rail. The screw holes 14 of the mounting base can be fixed by screws, providing two installation methods. The mounting port 5 is used to install the connector 6 and the cover 7. The cover 7 is fixed by snap-fit ​​with the fixing groove of the terminal housing 1 and the auxiliary post and the auxiliary groove through the fixing clip. The wire clamping screw in the wire clamping port of the connector 6 is used to fix the cables of each interface.

[0034] The usage process is as follows: First, according to the installation requirements, the terminal housing 1 is snapped onto the guide rail using the elastic clips 15 or fixed with screws through the screw holes 14; if multiple terminals need to be spliced, the clips 12 and limiting points 13 of one terminal housing 1 are snapped into the corresponding slots 10 and limiting slots 11 of another terminal housing 1 to complete the splicing; remove the cover 7, connect the main cable to the main wiring port of the connector 6 through the cable inlet hole 2, and tighten it with the wire clamping screw in the wire clamping port; connect each branch line to the connector through the outlet hole 3. Connect the corresponding outlet of the connector 6 and fix it with the corresponding wire clamping screw; if series splicing is required, remove the baffle of the spare hole 4, connect the bridge wire through the spare hole 4 to the spare port of the connector 6, and fix it with the wire clamping screw to realize the series connection of multiple terminals; install the color marking block 9 corresponding to the phase sequence in the snap-fit ​​hole of the cover 7, and install the marking strip 8 with the corresponding number printed in the snap-fit ​​groove; snap the fixing card of the cover 7 into the fixing groove of the terminal housing 1, and snap the auxiliary post into the auxiliary groove to complete the installation of the cover 7, and it can be put into use.
